According to the information recorded on the recording object 100 , the magnetic data reading unit 40 moves along the longitudinal direction of the main body front portion 17 again, and writes magnetic information into the magnetic stripe 110 . Then, the transport unit 30 transports the object to be recorded 100 to the front side, and ejects the object to be recorded 100 from the insertion port 18 .

FIG. 5 is a perspective view showing the main body front portion 17 provided with the magnetic data reading unit 40 . The magnetic data reading portion 40 has: two magnetic head guide shafts 470, 472 arranged in parallel with the longitudinal direction of the main body front portion 17, supported on the above-mentioned magnetic head guide shafts 470, 472, along the longitudinal direction of the main body front portion 17 (in the figure The head unit 400 that reciprocates, a part of the head drive belt 480 that is fixed on the head unit 400, the head motor 420 that drives the head drive belt 480 in order to reciprocate the head unit 400, near the head motor 420 The control board 440 provided at the lower part of the front part 17 of the main body is electrically connected to the magnetic head unit 400 and the flexible cable 450 of the control board 440 .

The magnetic head unit 400 has a magnetic head 410 that scans the magnetic stripe 110 of the recording object 100 by being driven by the magnetic head driving belt 480 . The magnetic head 410 reads information from the magnetic stripe 110 by scanning the magnetic stripe 110 .

FIG. 6 is an enlarged perspective view showing the vicinity of the magnetic head unit 400 in FIG. 5 , and FIG. 7 is a bottom perspective view of the portion shown in FIG. 6 viewed from the bottom. The magnetic head unit 400 has a substantially U-shaped shape, and magnetic head guide shafts 470 and 472 are inserted into a pair of opposing parallel side surfaces. On the upper surface of the magnetic head unit 400 , a magnetic head 410 is sandwiched between a pair of side surfaces facing upward. A substrate 432 is mounted on the bottom surface of the magnetic head unit 400 . A decoder 430 for converting information read by the magnetic head 410 into a digital signal, and a connector 460 for outputting the digital signal converted by the decoder 430 to the flexible cable 450 are mounted on the substrate 432 . Furthermore, the magnetic head unit 400 holds and fixes a part of the magnetic head driving belt 480 on the bottom surface.

According to the above structure, when the magnetic data reading part 40 reads the information of the magnetic stripe 110 arranged on the bottom surface of the object 100 to be recorded, first, the conveying part 30 conveys the object to be recorded 100 to the side where the magnetic stripe 110 is positioned at the front of the magnetic head 410. read position above. In this state, the head motor 420 rotates and drives the head drive belt 480 , so that the head unit 400 is pulled by the head drive belt 480 and reciprocated along the longitudinal direction of the front body 17 while being guided by the head guide shafts 470 and 472 . Thereby, the magnetic head 410 reads information from the magnetic stripe 110 while contacting and scanning the magnetic stripe 110 from below. At this time, the substrate 432 arranged on the magnetic head unit 400 and the decoder 430 mounted on the substrate 432 reciprocate together with the magnetic head 410, and the amplifying circuit of the decoder 430 amplifies the signal read by the magnetic head 410 from several mV to The A/D conversion circuit converts the amplified signal into a digital signal, and the demodulation circuit demodulates the digital signal and outputs it to the flexible cable 450 . The flexible cable 450 is bent by elastic deformation, following the reciprocating movement of the magnetic head unit 400 . Furthermore, the flexible cable 450 receives the digital signal from the decoder 430 and transmits it to the control board 440 . The control circuit provided on the control board 440 controls the magnetic head data reading unit 40 and the recording unit 20 based on digital signals from the flexible cable 450 .

After recording such as printing is performed on the recording object 100 by the recording unit 20 , the head data reading unit 40 writes the key point and the like into the magnetic stripe 110 . At this time, the flexible cable 450 transmits the analog signal from the control board 440 to the magnetic head 410 , and the magnetic head 410 writes to the magnetic stripe 110 while scanning the magnetic stripe 110 based on the analog signal.

As described above, the information read from the magnetic head 410 is converted into a digital signal by the decoder 430 installed near the magnetic head 410 and sent to the flexible cable 450, so even if there is noise in the middle of the transmission by the flexible cable 450, it is possible to prevent setting The control circuit on the control substrate 440 misreads the signal. In particular, noise is easily generated from the head motor 420 , but digital signals are transmitted through the flexible cable 450 near the head motor 420 , so it is easy to distinguish noise from signals, and erroneous reading of signals in the control board 440 can be suppressed.

In addition, in the embodiments shown in FIG. 5 to FIG. 7 , the decoder 430 is mounted on the substrate 432 , wherein the substrate is disposed on the bottom surface of the magnetic head unit 400 . However, the position where the decoder 430 is installed is not limited thereto. As another example, when the magnetic head 410 has a magnetic pole 412, a coil (not shown), and a magnetic shield 416 surrounding the magnetic pole 412 and the coil, the decoder 430 may also be It is surrounded by the magnetic shield 416 and incorporated into the magnetic head 410 . Accordingly, noise is less likely to be trapped between the magnetic head 410 and the decoder 430 , and the digital signal converted by the decoder 430 is output from the magnetic head 410 . Therefore, it is possible to prevent the control circuit provided on the control board 440 from misreading the signal.

Both ends of the pressure roller 310 are inserted into a shaft support portion 382 which rotatably pivotally supports the pressure roller unit 304 .

As shown in FIGS. 9 and 10 , the pushing unit 340 has: a correction pushing torsion bar 342 that pushes the pressure roller shaft 312 downward, and pushes the pressure roller downward with a force greater than that of the correction pushing torsion bar 342 . The shaft 312 is conveyed with a torsion bar 344 . In the present embodiment, the correction pushing torsion bar 342 is a metal wire, and is folded halfway at a substantially right angle. One end of the correction pushing torsion bar 342 is attached to the spring mounting portion 346 , and the other end is in contact with the pressure roller shaft 312 . The bent portion of the correction pushing torsion bar 342 is locked to the locking portion 347 . The torsion bar 342 for correction pushing is twisted about the axis, and pushes the pressing roller shaft 312 downward. The conveying torsion bar 344 is a metal wire having a larger diameter than the correction pushing torsion bar 342 , and is folded halfway at a substantially right angle. One end of the conveyance torsion bar 344 is attached to the spring mounting portion 346 , and the other end is in contact with the pressure roller shaft 312 . The bent portion of the transport torsion bar 344 is locked to the locking portion 348 . The conveyance torsion bar 344 is twisted about its axis, and pushes the pressure roller shaft 312 downward.

The correction pushing torsion bar 342 always pushes the pressure roller shaft 312 downward in order to press the pressure roller 310 against the object 100 including when the object 100 is aligned in the transport direction. Moreover, the transport torsion bar 344 is pushed by the pushing mechanism 350 shown in FIG. Pressing the pressure roller 310 pushes the pressure roller shaft 312 downward. The pressure roller shaft 312 has a V-shaped groove 314 substantially in the center where the pair of pressure rollers 310 are provided, and the transport torsion bar 344 pushes the pressure roller shaft 312 in the V-shaped groove 314 of the pressure roller shaft 312 . In addition, one end of the torsion bar 344 for conveyance is inserted into a vertically long groove 355 provided in the spring-side pushing member 354 . In addition, the pushing unit 340 is also an example of the roller pressing device of the present invention.

Thus, the torsion bar 342 for correction push and the torsion bar 344 for conveyance press the pressure roller unit 304 to the object 100 in two stages with different strengths, so it is different from using two coil springs and a sleeve pushed by the coil springs. Compared with the case of the tube, the mechanism for pushing the pressure roller unit 304 can be reduced.

Further, the correction pushing torsion bar 342 and the conveying torsion bar 344 push the pressure roller shaft 312 connecting the pair of pressure rollers 310 in each group having the pair of pressure rollers 310 . Accordingly, the correction pushing torsion bar 342 and the conveyance torsion bar 344 can uniformly push each pressure roller 310 in a set of pressure rollers 310 .

In addition, as shown in FIG. 10 , a pressure-side transmission gear 311 is connected to the right end of the pressure roller unit 304 , and the pressure roller 310 is rotationally driven by transmitting the driving force from the front conveyance unit 320 . The pressure roller unit 304 is pivotally supported by the U-shaped shaft support portion 382 so that the pressure-side transmission gear 311 can integrally rotate and drive the pressure roller unit 304 .

11 is a time chart showing the operation of the recording device 10 transporting the object 100 inserted into the recording device 10 to the front of the platen section 50 , performing calibration thereafter, and transporting the object 100 inserted into the recording device 10 to the platen section 50 after calibration.

As shown in FIG. 11 , in the standby state before the object to be recorded 100 is inserted into the recording apparatus 10 , the pressure roller 310 and the transport roller 324 are in a stopped state. In this standby state, both the correction plate 360 and the pushing member 351 of the pushing mechanism 350 to be described later are positioned upward, and the conveying torsion bar 344 does not push the pressure roller shaft 312 . In addition, the correction pushing torsion bar 342 is in a state of pushing the pressure roller shaft 312 .

After the object to be recorded 100 is inserted into the recording device 10 from the above-mentioned standby state, the pressure roller 310 and the transport roller 324 rotate to sandwich the object to be recorded 100 and transport it to a position where it comes into contact with the correction plate 360 . At this time, when the object to be recorded 100 is inclined relative to the conveying direction, a part of the object to be recorded 100 is in contact with the correction plate 360 first, and other parts of the object to be recorded 100 are not in contact with the correction plate 360 yet. In this state, after the pressing roller 310 and the conveying roller 324 rotate further, the portion of the object to be recorded 100 that has not yet been in contact with the correction plate 360 is conveyed by the pressing roller 310 and the conveying roller 324 arranged near the portion to the point where it is in contact with the correction plate 360 . The position where the correction plate 360 is in contact, and the portion that has been in contact with the correction plate 360 before, is not conveyed further. At this time, since the pressure roller 310 is pushed toward the object 100 by the correction pushing torsion bar 342 having a weaker urging force, the pressure provided near the part of the object 100 that has been in contact with the correction plate 360 before is The roller 310 and the transport roller 324 idle on the object 100 to be recorded. After the optical sensor (not shown) provided near the correction plate 360 determines that the object to be recorded 100 has been corrected, the rotation of the pressure roller 310 and the transport roller 324 is stopped.

After the recorded object 100 is calibrated, the pushing member 351 descends. As a result, the pushing member 351 brings the pushed up transport torsion bar 344 into contact with the V-shaped groove 314 of the pressure roller shaft 312 . Then, the correction plate 360 is also lowered in conjunction with the continued lowering of the pushing member 351 after it has been lowered to a predetermined position. After the correction plate 360 descends to a position retracted from the conveyance path of the object to be recorded 100 , it stops at this position, and the pushing member 351 also stops descending accordingly.

After the correction plate 360 and the pushing member 351 stop, the pressure roller 310 and the conveying roller 324 rotate again to sandwich the object 100 to be recorded and convey it to the platen portion 50 for recording by the recording portion 20 . At this time, the pressure roller 310 is pushed toward the object to be recorded 100 with a strong pushing force via the pressure roller shaft 312, the correcting pushing torsion bar 342 and the conveying torsion bar 344, so the pressure roller 310 and the conveying roller 324 can reliably grip and transport the object to be recorded 100 .

FIG. 12 is a partial sectional view of the pushing mechanism 350 . In FIG. 12 , a state in which the correction plate 360 retreats from the conveyance path of the object 100 to be recorded and the pressure roller 312 is pushed by the conveyance torsion bar 344 is shown.

As shown in FIG. 12 , the pushing mechanism 350 has a spring-side pushing member 354 provided with a groove 355 into which the torsion bar 344 for conveyance is inserted, and a follower side that contacts the lower surface of the spring-side pushing member 354 The pushing member 352, the plate-shaped following member 368 extending in the vertical direction integrally with the follower side pushing member 352, and the cam shaft 394 is rotatably supported on the main body portion 11, so that the following member 368 acts as a follower. The first cam 390 that reciprocates up and down. The spring-side pushing member 354 and the follower-side pushing member 352 constitute the pushing member 351 .

As described above, the follower member 368 is integrally formed with the follower-side pushing member 352 at the upper part. Further, a correction plate 360 is provided on the upper portion of the follower member 368 via a coil spring 362 . At a substantially central position in the vertical direction of the follower member 368 , a vertically long elongated hole 364 is provided, and a cam shaft 394 of the first cam 390 is inserted into the elongated hole 364 . In addition, a notch 366 opening downward is provided at a lower portion of the follower member 368 , and a follower fixing shaft 396 fixed to the main body portion 11 is inserted into the notch 366 . A cam follower pin 398 penetrates between the long hole 364 and the notch 366 of the follower member 368 .

The first cam 390 has a substantially disc shape, and has a spiral cam groove 392 on the side facing the follower member 368 . One end of a cam follower pin 398 inserted through the follower member 368 is inserted into the cam groove 392 .

In the state shown in FIG. 12 , the cam follower pin 398 is at a downward position away from the cam shaft 394 in the swirl-shaped cam groove 392 . Accordingly, the follower member 368 is positioned at the lowest position in the movable range with respect to the main body portion 11 supporting the camshaft 394 . When the follower member 368 is at the lowermost position, the correction plate 360 provided above the correction plate 360 is located below the conveyance path of the object 100 to be recorded and avoided from the conveyance path. Similarly, the follower side push member 352 connected to the upper part of the follower member 368 is also at the lowest position, and the spring side push member 354 in contact with the follower side push member 352 allows the torsion bar 344 for conveying to push the pressure roller shaft. 312.

In order to change from this state to the standby state, the first cam 390 is rotationally driven in the direction of the arrow of the solid line in FIG. 12 by a drive mechanism not shown. When the first cam 390 rotates in the arrow direction, the cam follower pin 398 moves up relative to the first cam 390 along the cam groove 392 . At this time, because the camshaft 394 and the follower fixing shaft 396 are inserted into the long hole 364 and the notch 366, when the first cam 390 rotates in the direction of the arrow, the follower 368 can be moved relative to the camshaft 390 without being skewed to the left and right. The main body part 11 rises.

13 is a partial cross-sectional view showing a state where the correction plate 360 enters the conveyance path of the object to be recorded 100 and the conveyance torsion bar 344 is separated from the pressure roller shaft 312. From the state shown in FIG. 12 , when the first cam 390 rotates and the follower member 368 rises, the upper end of the correction plate 360 comes into contact with the bottom surface 384 of the pressure roller side frame 380 as shown in FIG. 13 . Thus, the correction plate 360 enters the conveyance path of the object 100 to be recorded.

After the first cam 390 rotates further from this state, since the correction plate 360 is in contact with the bottom surface 384, it will not continue to rise, but because the coil spring 362 is arranged between the correction plate 360 and the follower member 368, the follower member 368 Continue to rise while overcoming the impelling force of the coil spring 362 . Along with this, the follower-side pushing member 352 connected to the upper portion of the follower member 368 also rises, pushing the spring-side pushing member 354 in contact with the follower-side pushing member 352 . Accordingly, the spring-side pushing member 354 pushes one end of the conveying torsion bar 344 inserted into the groove 355 , moves the conveying torsion bar 344 above the pressure roller shaft 312 , and releases the pushing force on the pressure roller shaft 312 . Thereby, when the object to be recorded 100 is corrected in the conveying direction, the push of the conveying torsion bar 344 can be released from the pressure roller shaft 312 . This state is the standby state shown in FIG. 11. After the object to be recorded 100 is inserted into the recording device 10, the object to be recorded 100 is pinched and rotated by the pressure roller 310 and the conveying roller 324, and the object to be recorded 100 is conveyed to contact with the calibration plate 360. Correction.

After the calibration of the object to be recorded 100 is completed in the state shown in FIG. 13 , the first cam 390 is rotationally driven in the direction of the dotted arrow shown in FIG. 13 by the above-mentioned drive mechanism. When the first cam 390 rotates in the direction of the arrow, the cam follower pin 398 descends relative to the first cam 390 along the cam groove 392 . As a result, the follower member 368 descends relative to the main body 11 . At this time, first, since the follower-side pushing member 352 integrally formed with the correction plate 360 descends, the spring-side pushing member 354 in contact with the follower-side pushing member 352 also descends. One end of the conveyance torsion bar 344 pushed by the spring-side pushing member 354 descends downward, and the conveyance torsion bar 344 is inserted into the groove 314 of the pressure roller shaft 312 again to push the pressure roller shaft 312 downward. As shown in FIGS. 9 and 10, since the torsion bar 344 for conveyance pushes the pressure roller shaft 312 in the V-shaped groove 314 provided on the pressure roller shaft 312, even if the pressure roller shaft 312 temporarily rises and separates, it can be moved every time. Each time, the pressure roller shaft 312 is pushed at substantially the same position. Also, even when the pressure roller shaft 312 is rotationally driven, it is possible to push the pressure roller shaft 312 in a direction perpendicular to the rotation shaft while rotationally driving the pressure roller shaft 312 .

And, when the first cam 390 rotates in the arrow direction of the dotted line, the follower member 368 further descends, and along with it, the correcting plate 360 also descends to escape from the conveyance path of the object to be recorded 100, and returns to the state shown in FIG. 12 .

14 and 15 are cross-sectional views showing the rear pressurizing portion 302 cut along a plane perpendicular to the rotation axis. FIG. 14 is cut with a plane through slot 314 , and FIG. 15 is cut with a plane through shaft support 332 of rear frame 330 . 14 and 15, the pressure roller unit of the rear pressure unit 302 has the same structure as the pressure roller unit 304 of the front pressure unit 300, so the same symbols as the pressure roller unit 304 are used for description.

As shown in FIGS. 14 and 15 , the rear pressure unit 302 has a pressure roller unit 304 , a rear frame 330 that rotatably supports the pressure roller unit 304 , and pushes the pressure roller unit 304 downward toward the object 100 to be recorded. The pushing part 334. On the rear frame 330, a shaft support portion 332 having a U-shape is provided. The pressure roller shaft 312 is inserted into the shaft support portion 332 , and the pressure roller shaft 312 is rotatably supported. By pivotally supporting the pressure roller unit 304 on the shaft support portion 332 , the pressure roller unit 304 can be rotationally driven integrally.

The pushing portion 334 is a metal wire, and pushes the pressure roller unit 304 downward toward the recording object 100 in the V-shaped groove 314 . Since the pressing roller shaft 312 is formed of resin and the pushing portion 334 is formed of metal, even if the pressing roller shaft 312 is rotated, the pushing portion 334 can move in a direction perpendicular to the rotation axis by sliding the pushing portion 334 relative to the pressing roller shaft 312. direction to push the pressure roller 312 more reliably. Therefore, the mechanism for pressing the pressure roller unit 304 can be reduced compared to the case where the pressure roller shaft 312 on both sides of each pressure roller 310 is pressed by a coil spring and a bush pushed by the coil spring.

FIG. 16 is a partial rear view showing an operation in which the front pressurization unit 300 and the front transport unit 320 sandwich and transport the object to be recorded 100 . In addition, since the rear pressurization part 302 and the rear conveyance part 322 carry out the same operation|movement also when the object to be recorded 100 is conveyed, the description is abbreviate|omitted.

As shown in FIG. 16 , the pressure roller 310 corresponding to the width of the object 100 in the pressure roller unit 304 after the object 100 to be recorded is arranged between the pressure roller unit 304 and the front conveying part 320 just leans against the object to be recorded. Record 100 on. In this state, by rotationally driving the pressure roller shaft 312 , the pressure roller unit 304 is rotationally driven via the conveyance-side transmission gear 321 and the pressure-side transmission gear 311 . Therefore, not only when the object to be recorded 100 has the narrowest width or the widest width conceivable, but also in the case of any width, the pressure roller 310 will abut on the object to be recorded 100, The object to be recorded 100 is accurately conveyed by pinching the object to be recorded 100 between the front conveying part 320 in a state where the pressure roller unit 304 as a whole is not inclined relative to the object to be recorded 100 . In particular, among the pair of pressure rollers 310 , even if one of the pressure rollers 310 abuts, the pusher 340 can push both pressure rollers 310 evenly. Moreover, since the universal joint 370 in the pressure roller unit 304 is not directly pushed and does not receive a force in the radial direction, when the pressure roller unit 304 is rotated by applying a driving force, the pressure roller unit 304 It can rotate smoothly without shaking, suppresses the vibration of the object 100 to be recorded, and improves recording accuracy.

FIG. 17 is an enlarged cross-sectional view showing the vicinity of the table portion 50 in FIG. 4 , and FIG. 18 is a cross-sectional view viewed from above by cutting the part of FIG. 17 along a horizontal plane indicated by X. In addition, the cut surface of FIG. 17 is inside (the left side in FIG. 18 ) compared to the cut surface of FIG. 4 .

As shown in FIGS. 17 and 18 , the platen portion 50 has: a platen 500 disposed below the recording head 200, a support spring 550 pushing and supporting the platen 500 from below, and a support spring 550 that pushes and supports the platen 500 from below, and is provided in a direction opposite to that in which the recording head 200 reciprocates. The support spring 550 is at the same position, the table height limiter 560 that limits the upper limit of the height of the table 500 , the table guide members 532 and 534 that guide the movement of the table 500 in the vertical direction, and the vibration absorbing member provided under the table 500 540. On the recording head 200 , a roller serving as a gap maintaining portion 220 is attached rotatably with respect to the recording head 200 .

The platen 500 has a plate-shaped platen body 510 extending in the moving direction of the recording head 200 , and a pair of platen legs 520 extending downstream of the platen body 510 in the transport direction of the object 100 to be recorded. . The top body 510 and the top leg 520 are integrally formed, for example, by injection molding elastic resin. At both ends of the platen body 510 in the moving direction of the recording head 200 , pins 515 , 516 protruding outward in the moving direction of the recording head 200 are also provided.

The platen main body 510 has an upper portion 512 with a flat upper surface facing the recording head 200 , and a lower portion 514 narrower than the upper portion 512 in the conveyance direction of the object 100 to be recorded. Accordingly, the cross section of the table main body 510 has an umbrella shape as shown in FIG. 17 . While the gap maintaining unit 220 rotates on the upper surface of the upper part 512 and on the object to be recorded 100 conveyed thereon, the gap maintaining unit 220 and the recording head 200 move along the longitudinal direction of the upper part 512 . At this time, the gap maintaining part 220 presses down the upper surface of the upper part 512 directly or through the object to be recorded 100 , thereby maintaining the gap between the object to be recorded 100 and the recording head 200 . The table leg portion 520 regulates the upper limit of the height of the table 500 pushed by the support spring 550 by contacting the table height regulating portion 560 described later.

The platen guide members 532 and 534 are provided on both ends of the platen 500 in the direction in which the recording head 200 reciprocates, and stand vertically upward from the main body 11 . The platen guide members 532 and 534 each have guide grooves 533 and 535 in the vertical direction. The guide grooves 533 , 535 guide the vertical movement of the table 500 by inserting the pin 515 of the table 500 into the guide groove 533 and inserting the pin 516 of the table 500 into the guide groove 535 . In addition, the lower limit of the height of the table 500 is regulated by contacting the bottom surfaces of the table guide members 532 and 534 with the pins 515 and 516 . Moreover, the height of the bottom surface is set so that even when the platen 500 is pressed by the thickest object to be recorded 100 conceived for recording, the pins 515, 516 do not interfere with the platen guide members 532, 534. bottom surface contact.

The shock-absorbing member 540 is formed of a sound-absorbing and elastic material such as sponge, and is provided between the correction plate 360 and the back side in the direction in which the object to be recorded 100 is transported so as to cover the lower part 514 of the platen 500 and a part of the side surface. Between the conveying parts 322 . The vibration absorbing member 540 is in close contact with the platen leg portion 520 of the platen 500 and sandwiches the object 100 to be recorded from both sides in the conveying direction. And, the vibration absorbing member 540 pushes the table top 500 toward the table guide members 532 and 534 . In the embodiment shown in FIGS. 17 and 18 , the upstream side of the vibration absorbing member 540 in the conveyance direction of the object 100 is inserted in a state of being more deeply crushed than the downstream side in the direction along the conveyance direction. The lower portion 514 of the deck 500 . Accordingly, in the vibration absorbing member 540 , the urging force applied to the lower portion 514 of the platen 500 from the upstream side in the conveyance direction is stronger than the urging force applied from the downstream side. Therefore, the entire platen 500 is pushed downstream, and the pins 515 and 516 of the platen 500 are pressed against the downstream side walls of the object to be recorded 100 in the guide grooves 533 and 535 , respectively. Accordingly, the vibration absorbing member 540 can push the table 500 in a direction perpendicular to the vertical direction in which the table 500 vibrates, and absorb the vibration of the table 500 more reliably.

Here, between the lower surface 513 of the upper portion 512 of the table 500 and the upper surface 542 of the vibration absorbing member 540, there is provided a gap G that is smaller than the movement width of the table 500 in the vertical direction. Accordingly, when the vertical movement amount of the table 500 is small, the vibration absorbing member 540 absorbs the vibration by the thrust force in the direction perpendicular to the direction in which the table 500 vibrates. Furthermore, when the vertical movement amount of the table 500 is large, the vibration absorbing member 540 contacts the upper part 512 of the table 500 and absorbs the vibration of the table 500 also in the vertical direction. Therefore, the platen 500 can follow the downward pressing of the recording head 200 , and the subsequent vibration of the platen 500 can be more reliably absorbed by the vibration absorbing member 540 .

19 and 20 are schematic diagrams illustrating a state in which the platen 500 is bent when pressed downward by the gap maintaining portion 220 . FIG. 19 shows the state where the recording head 200 is close to the standby position, and FIG. 20 shows the state where the recording head 200 is located at the approximate center of the reciprocating movement. In addition, arrows in the figure indicate positions where the height of the table top 500 is restricted by the table height regulating portion 560 .

The operation of the table portion 50 will be described using the configuration shown in FIGS. 17 to 20 . First, the transport unit 30 transports the object to be recorded 100 corrected in the transport direction onto the flat upper surface of the upper portion 512 of the platen 500 . Then, the recording head carriage 230 is guided and moved on the recording head guide shaft 260 provided along the longitudinal direction of the main body upper part 16 by driving the timing belt 250 described later by the carriage motor 240 . Thus, the recording head carriage 230 moves the recording head 200 and the gap maintaining portion 220 in the longitudinal direction of the platen 500 . In this case, in the area where the object 100 to be recorded is not placed on the upper portion 512 of the platen 500 , the gap maintaining unit 220 directly rotates on the upper portion 512 . In addition, in the area where the object to be recorded 100 is placed on the upper part 512 of the platen 500, the gap holding part 220 rides on the object to be recorded 100 and rotates on the object to be recorded 100, so that the gap holding part 220 is pressed by the object to be recorded 100. The upper surface of the upper portion 512 of the deck 500 . Thus, the gap maintaining unit 220 maintains a desired gap between the recording head 200 and the object to be recorded 100 provided on the upper portion 512 of the platen 500 . Even in the state where the gap maintaining part 220 is directly rotated from the upper part 512 of the platen 500, when the platen 500 is suddenly pressed by being placed on the object 100 to be recorded, the lower part 514 of the platen 500 and the vibration absorbing member 540, and the sliding load that the pins 515, 516 of the platen 500 are pressed against the side wall on the downstream side of the object 100 in the guide grooves 533, 535, can also attenuate the vibration of the platen 500. , quickly and reliably absorb the vibration of the platen 500 .

As described above, the gap maintaining part 220 rotates on the object to be recorded 100, and while the desired gap is maintained between the object to be recorded 100 and the recording head 200, the ink ribbon of the ink ribbon cassette 60 passes by the recording head 200 on the object to be recorded. A plurality of metal wires are struck on the 100 to record dots, thereby recording characters and the like on the object 100 to be recorded. In the present embodiment, the vibration absorbing member 540 is abutted against the lower portion 514 of the platen 500, so even if the vibration of striking the wire onto the object 100 to be recorded is transmitted to the platen 500, the platen can be absorbed. 500 vibrations.

As shown in FIGS. 19 and 20 , a support spring 550 pushing and supporting the table 500 from below and a table height restricting portion 560 restricting the upper limit of the height of the table 500 are provided at the same position in the longitudinal direction. The platen 500 has elasticity as described above, and is pressed down by the object 100 to be recorded, and bends as indicated by a dotted line in the figure. However, for convenience of explanation, the curvature is exaggerated and shown by a dotted line. In addition, the dotted lines in the figure will be described later.

FIG. 21 is a side view of the platen 500 viewed from the direction in which the recording head 200 reciprocates. The deck 500 has the deck body 510 and the deck legs 520 as described above. The platen foot portion 520 has a vertical portion 522 extending vertically downward from two places of the platen body 510, and a horizontal portion 524 horizontally extending from the lower end of the vertical portion 522 to the downstream in the conveying direction of the object 100 to be recorded. L shape. The upper surface 525 of the horizontal portion 524 is in contact with a contact portion 564 of a table height regulating portion 560 to be described later, thereby restricting the upper limit of the height of the table 500 pushed by the support spring 550 .

FIG. 22 is a perspective view of the platen height limiting portion 560 . The platen height limiting portion 560 has a flat plate-shaped spring support portion 562 in contact with the lower end of the support spring 550 that pushes the platen 500, protrudes from the spring support portion 562, and is inserted into the support spring 550 to guide and lock the support in the vertical direction. The spring lock portion 563 of the spring 550 is provided at the contact portion 564 downstream of the spring lock portion 563 in the transport direction of the object 100 to be recorded, and at one end side of the platen height limiting portion 560 in the direction in which the recording head 200 reciprocates ( The right side in the figure), the shaft portion 568 extending along the transport direction of the object to be recorded 100 .

The contact portion 564 has a lower surface 565 that has a gap between the lower surface 565 and the spring support portion 562 and is positioned higher than the spring support portion 562 . The contact portion 564 is provided with a long hole 566 that penetrates the contact portion 564 and is long in the reciprocating direction of the recording head 200 . Furthermore, a threaded hole 567 is provided at a position farther from the shaft portion 568 than the elongated hole 566 in the platen height regulating portion 560 .

23 to 26 are schematic diagrams illustrating the platen height regulating unit 560 and the height adjusting unit 570 . FIG. 23 is a perspective view of the vicinity of the platen height regulating portion 560 viewed from the conveying direction of the object to be recorded 100 . FIG. 24 is a cross-sectional view showing the part of FIG. 23 taken along a plane perpendicular to the moving direction of the recording head 200 . FIG. 25 is a cross-sectional view showing a section in FIG. 24 by cutting A. FIG. FIG. 26 is a cross-sectional view showing the part of FIG. 24 taken along a section B. FIG.

As shown in FIG. 23 , the spring support portion 562 of the table height regulating portion 560 supports the support spring 550 by contacting the lower end of the support spring 550 . Accordingly, the support spring 550 pushes the platen 500 toward the recording head 200 relative to the platen height restricting portion 560 . In addition, the lower surface 565 of the contact portion 564 of the table height regulating portion 560 contacts the upper surface 525 of the horizontal portion 524 of the table leg 520 of the table height regulating portion 560 to restrict the upward movement of the table leg 520 . Accordingly, the table height limiting portion 560 limits the upper limit of the height of the table 500 pushed by the support spring 550 . Further, in the contact portion 564 , a penetration portion 569 having a rectangular through hole penetrating to the main body portion 11 is provided below the insertion horizontal portion 524 . Thereby, when the table top 500 is pressed by the gap maintaining portion 220 , the table leg portion 520 of the table top 500 can retract into the through portion 569 .

The shaft portion 568 of the table height regulating portion 560 rotatably pivotally supports the height regulating portion holding portion 580 fixed to the main body portion 11 . As a result, the table height regulating portion 560 rotates around the shaft portion 568 , and the heights of the spring support portion 562 and the contact portion 564 provided on the table height regulating portion 560 relative to the main body portion 11 can be adjusted.

As shown in FIGS. 24 to 26 , in the elongated hole 566 of the contact portion 564 of the platen height limiting portion 560 , there is a gap between the contact portion 564 and a pressing screw 574 is inserted. The upper surface of the contact portion 564 contacts, and the front end portion of the pressing screw 574 is screwed into a screw hole 576 provided on the body portion 11 . Thereby, the pressing screw 574 presses the table height restricting part 560 with respect to the main body part 11, and the upper limit of the height of the table height restricting part 560 is defined. In addition, a push-up screw 572 is screwed into the threaded hole 567 of the platen height regulating portion 560 , and the tip of the push-up screw 572 comes into contact with the main body portion 11 . Thereby, the push-up screw 572 pushes the table height restricting part 560 relative to the main body part 11, and the lower limit of the height of the table height restricting part 560 is defined. The aforementioned pushing screw 572 and pressing screw 574 are an example of the height adjustment unit 570 in the present invention.

In the above configuration, by rotating the pushing screw 572 in the direction of pushing in the table height regulating part 560 and rotating the pressing screw 574 in the direction of floating from the main body part 11, the contact part 564 of the table height regulating part 560 The following 565 moves up. As a result, the upper limit of the height of the platen 500 moves upward, and the height of the platen 500 relative to the recording head 200 becomes higher when the gap holding portion 220 of the recording head 200 is not in contact. In addition, by rotating the pushing screw 572 in the direction of floating from the table height regulating part 560 and rotating the pressing screw 574 in the direction of pressing in the main body part 11, the lower surface 565 of the contact part 564 of the table height regulating part 560 Move Downward. As a result, the upper limit of the height of the platen 500 moves downward, and the height of the platen 500 relative to the recording head 200 becomes lower when the gap holding portion 220 of the recording head 200 is not in contact. Through the above operations, the height adjusting part 570 can adjust and fix the height of the platen height restricting part 560 relative to the recording head 200 . In this case, even if the upper limit of the height of the platen 500 relative to the recording head 200 is changed, the relative position between the spring support portion 562 of the platen height limiting portion 560 and the platen 500 does not change, so the spring support portion 562 of the platen height limiting portion 560 can be set at the spring support. The supporting spring 550 between the portion 562 and the platen 500 pushes the platen 500 with a substantially constant driving force.

As shown in FIG. 25 , the pushing screw 572 is provided farther from the shaft portion 568 than the pressing screw 574 . As a result, when the platen 500 is pressed down by the gap maintaining portion 220 and a downward force acts on the platen height regulating portion 560 , the platen height regulating portion 560 is stably supported by the shaft portion 568 of the pressing screw 574 and the pushing screw 572 . part 560, so it is possible to prevent deformation or damage of the platen height restricting part 560.

As shown in FIG. 26 , in the direction in which the recording head 200 reciprocates, the support spring 550 and the platen height restricting portion 560 are provided at the same position. Therefore, when the table top 500 is not pressed by the gap maintaining part 220, it is possible to reduce the gap between the position pushed by the support spring 550 on the table top 500 and the position whose height is restricted by the table height regulating part 560. The bending moment can suppress plastic deformation and creep of the platen 500 over time.

Furthermore, as shown in FIG. 24 , the pressing screw 574 is provided near the contact portion 564 in the conveying direction of the object to be recorded 100 . Thereby, the bending moment generated between the position pressed by the pressing screw 574 and the contact portion 564 pushed by the table leg 520 in the table height restricting portion 560 can be reduced, and the deformation of the table height restricting portion 560 over time can be suppressed. resulting in plastic deformation and creep.

FIG. 27 is a schematic diagram illustrating the amount of displacement of the table 500 when the gap maintaining portion 220 is moved onto the table 500 . In FIG. 27 , assuming that the platen 500 is a rigid body, when the gap maintaining portion 220 presses the platen 500 downward with a certain force, the position of the platen 500 pressed by the gap maintaining portion 220 is fixed by the support spring 550 . The amount of displacement, expressed as "spring-based displacement". In addition, in this figure, assuming that the platen 500 is supported by a rigid body instead of the support spring 550, when the gap maintaining portion 220 presses the platen 500 downward with a certain force, the portion held by the gap of the platen 500 will The amount of displacement of the pressed position of the platen 500 by the elastic deformation of the platen 500 is expressed as "displacement due to elasticity".

When the gap maintaining portion 220 presses down on the platen 500 with a certain force, its positional displacement is the sum of the aforementioned spring-based displacement and elastic-based displacement. As shown in FIG. 27 , between a pair of support springs 550 , the sum of the spring-based displacement and the elastic-based displacement of the platen 500 is substantially constant. Therefore, the force required for the gap maintaining portion 220 to press the platen 500 with a constant displacement is substantially constant between the pair of support springs 550 . Thereby, when the gap maintaining part 220 reciprocates on the table 500 , it can stably press the table 500 .

28 and 29 are schematic diagrams illustrating the amount of displacement of the table 500 when the gap maintaining portion 220 moves on the table 500 in Comparative Example 1. FIG. 19 and 20, the same symbols are given to the same configurations, and description thereof will be omitted. In Comparative Example 1 shown in FIGS. 28 and 29 , unlike the present embodiment shown in FIGS. 19 and 20 , the platen height restriction parts 560 are provided at both ends of the platen 500 in the longitudinal direction. The upper limit of the height of the platform 500 is limited by the platform 500 .

In this comparative example 1, when the recording head 200 is in the state close to the standby position and at the approximate center of the reciprocating movement, the platen 500 is curved as indicated by dotted lines in FIGS. 28 and 29 , respectively. However, in the above-mentioned figures, the curvature is shown exaggeratedly for convenience of description. In FIG. 29 , the platen 500 is pressed downward near the center by the gap maintaining portion 220 and bent upward, both sides thereof are pushed upward by the support springs 550 , and both ends are bent downward. In addition, even in the state where the gap maintaining part 220 is not pressing the table top 500, since the position where the height is restricted by the table height restricting part 560 is closer to the end side than the position pushed by the support spring 550, it may occur on the table 500. The bending moment in the direction of the overall upward bulge. As mentioned above, the platen 500 of Comparative Example 1 may undergo plastic deformation or creep over time. In addition, for comparison, the curvature of this comparative example 1 is shown by the dotted line in FIG. 19 and FIG. 20 .

30 and 31 are schematic diagrams illustrating the amount of displacement of the table 500 when the gap maintaining portion 220 moves on the table 500 in Comparative Example 2. FIG. In Comparative Example 2 shown in FIGS. 30 and 31 , unlike the present embodiment shown in FIGS. 19 and 20 , the platen height regulating portion 560 is provided closer to the center than the support spring 550 in the longitudinal direction.

In this comparative example 2, when the recording head 200 is near the standby position and at the approximate center of the reciprocating movement, the platen 500 is curved as indicated by dotted lines in FIGS. 30 and 31 , respectively. However, in the above-mentioned figures, the curvature is shown exaggeratedly for convenience of description. In addition, for comparison, the curvature of the platen 500 in the present embodiment shown in FIGS. 19 and 20 is shown by dotted lines in FIGS. 30 and 31 , respectively. For example, as shown in FIG. 30 , the right end of the platen 500 is greatly deformed upward when the recording head 200 is positioned on the left. Moreover, even in the state where the gap maintaining part 220 is not pressing the table top 500, since the position where the height is restricted by the table height regulating part 560 is closer to the center side than the position pushed by the support spring 550, the table top 500 may be stuck. The bending moment in the direction of the overall downward bulge. As mentioned above, the platen 500 of Comparative Example 2 may also undergo plastic deformation or creep over time.

Compared with Comparative Example 1 and Comparative Example 2, in this embodiment, the support spring 550 and the platen height limiting portion 560 are provided at the same position in the longitudinal direction of the platen 500 , so when pressed by the gap holding portion 220 The bending time is small. In addition, even when the gap holding part 220 is not pressed, the bending generated between the position pushed by the support spring 550 and the position where the height is restricted by the table height regulating part 560 on the table 500 can be reduced. The torque can suppress plastic deformation and creep of the platen 500 over time.

In addition, in this embodiment, the support spring 550 may be located below the gap holding portion 220 at the standby position of the recording head 200 . Thus, even if the platen 500 is pressed down by the gap holding portion 220 while the recording head 200 is on standby, the bending moment generated between the position pushed by the support spring 550 and the position where the height is restricted by the gap holding portion 220 can be reduced. , it is possible to suppress plastic deformation and creep of the platen 500 over time.

FIG. 32 is an enlarged perspective view showing the vicinity of the ribbon winding unit 600 of the recording device 10 in an enlarged manner. In addition, in FIG. 32, the state which removed the ink ribbon cassette 60 from the recording apparatus 10 is shown for convenience of description. In addition, from FIG. 32 to FIG. 36 described later, the teeth of the gear are omitted for simplification of the drawings.

As shown in FIG. 32 , the ribbon winding unit 600 is disposed near the belt drive pulley 610 that drives the timing belt 250 , and has a ribbon winding shaft 660 that cooperates with the reel of the ribbon cassette 60 . The belt drive pulley 610 is a gear fixed to the rotation shaft 242 of the carriage motor 240 shown in FIG. 3 . The belt drive pulley 610 rotates forward and reverse in order to drive the timing belt 250 back and forth, and the ribbon winding unit 600 rotates the ribbon winding shaft 660 in a certain direction when the belt drive pulley 610 rotates forward and reversely. , to wind the ribbon of the ribbon cassette 60.

FIG. 33 is a front view of the ribbon winding unit 600 . FIG. 34 is a perspective view of the planetary rod 620 and the planetary gear 700 . FIG. 35 is a perspective view of the ribbon winding unit 600 with the planetary lever 620 and the planetary gear 700 removed. FIG. 36 is a rear perspective view of the ink ribbon winding unit 600 viewed from the downstream side in the transport direction of the object to be recorded 100 . In addition, in FIG. 34, the planetary drive gear 710 is partially cut away for convenience of description, and the planetary driven gear 730 is shown floating from the planetary drive gear 710. FIG.

As shown in FIG. 33 , the ribbon winding unit 600 has: a sun gear 612 provided on the shaft of the rotating shaft 242, a planetary lever 620 meshed with the rotating shaft 242, a planetary gear 700 provided on the planetary lever 620, and When the planetary gear 700 meshes with the forward rotation driven gear 630 and the counter driven gear 640 that rotate with the planetary gear 700, the intermediate gear 650 that meshes with the counter driven gear 640 is always in contact with the forward rotation driven gear 630 and the intermediate gear 650. Engage the aforementioned ribbon take-up shaft 660. The ribbon winding unit 600 further includes a case 670 for accommodating the planetary lever 620 , the planetary gear 700 , the forward driven gear 630 , the counter driven gear 640 , the intermediate gear 650 , and the ribbon winding shaft 660 .

The sun gear 612 is integrally provided with the belt drive pulley 610 and has a smaller diameter than the belt drive pulley 610 , and is located closer to the carriage motor 240 than the belt drive pulley 610 in the axial direction of the rotation shaft 242 . Accordingly, the sun gear 612 rotates forward or reverse along with the rotation shaft 242 forward or reverse.

The transmission of the rotational driving force and the rotational direction of the ribbon winding unit 600 will be described using FIG. 33 . When the rotating shaft 242 rotates forward (in the direction of the dotted arrow in FIG. 33 ), the sun gear 612 arranged on the rotating shaft 242 also rotates forward. Along with this, the planetary lever 620 moves in the direction of the dotted arrow, and the planetary gear 700 provided on the planetary lever 620 revolves on the sun gear 612 , so that the planetary gear 700 meshes with the forward rotation driven gear 630 . In this state, when the sun gear 612 rotates forward, the planetary gear 700 also rotates forwardly, and the forward driven gear 630 rotates along with the planetary gear 700 to rotate in the direction of the dotted arrow in the figure. With this rotation of the forward rotation driven gear 630, the ribbon winding shaft 660 rotates in the direction of the dotted arrow in the figure.

In addition, when the rotation shaft 242 is reversed (in the direction of the solid arrow in FIG. 33 ), the sun gear 612 provided on the rotation shaft 242 is also reversed. Along with this, the planetary lever 620 moves in the direction of the solid arrow, the planetary gear 700 provided on the planetary lever 620 revolves on the sun gear 612 , and the planetary gear 700 meshes with the counter driven gear 640 . In this state, when the sun gear 612 is reversed, the planetary gear 700 is also reversed along with the rotation, and the counter driven gear 640 is rotated in the direction of the solid arrow in the figure along with the rotation of the planetary gear 700 . With this rotation of the counter driven gear 640, the intermediate gear 650 rotates in the direction indicated by the solid line in the figure. As the intermediate gear 650 rotates, the ribbon winding shaft 660 rotates in the direction of the solid arrow in the figure.

As shown in FIG. 34 , the planetary rod 620 has a generally plate-shaped body 622 , and a rotating shaft 720 is pierced near one end of the body 622 to hold the planetary gear 700 . At the other end of the main body 622 , there are provided a notch 623 in the shape of an arc concentric with the rotary shaft 242 and meshed with the rotary shaft 242 , and a convex portion 624 provided around the notch 623 . The convex portion 624 extends toward the carriage motor 240 along the axial direction of the rotation shaft 242 . Thus, the planetary rod 620 maintains the distance between the sun gear 612 and the planetary gear 700 . The notch 623 has an arc shape cut away from one end of the planetary rod 620 toward the planetary gear 700 side. Thus, even when the planetary gear 700 receives meshing pressure from the forward rotation driven gear 630 and the counter driven gear 640, the notch 623 of the planetary rod 620 contacts the rotation shaft 242, thereby preventing the planetary rod 620 from Come off from the rotating shaft 242 .

The planetary gear 700 has: a planetary driving gear 710 arranged on the planetary rod 620, meshing with the sun gear 612 and rotating with the sun gear 612; The driving gear 730 , the pushing member 740 that pushes the planetary driving gear 710 and the planetary driven gear 730 toward each other, passes through the planetary driving gear 710 , the planetary driven gear 730 and the rotation shaft 720 of the planetary rod 620 .

The planetary drive gear 710 has an approximately disk-like shape, and teeth 712 meshing with the teeth of the sun gear 612 are provided on the outer circumference. At the center of the planetary drive gear 710, a through hole for receiving a lower portion of the rotation shaft 720 is provided. On the outside of the through hole, a hole having a plurality of slopes 714 inclined with respect to the circumferential direction and the axial direction is provided.

The planetary driven gear 730 has a substantially cylindrical shape with a smaller diameter than the planetary drive gear 710 . On the upper portion of the outer periphery of the planetary driven gear 730 , teeth 732 that mesh with the normal rotation driven gear 630 and the counter rotation driven gear 640 are provided. A plurality of inclined surfaces 734 inclined with respect to the circumferential direction and the axial direction are provided on the lower portion of the outer periphery of the planetary driven gear 730 . The pushing member 740 pushes the planetary driven gear 730 toward the planetary driving gear 710 so that in a general state, the planetary driving gear 710 and the planetary driven gear 730 mesh with each other at the aforementioned plurality of slopes 714 , 734 .

The rotating shaft 720 has an approximately cylindrical shape with a flange 722 at its upper end. At the lower end 724 of the rotating shaft 720, a groove, not shown, is provided around the shaft, into which a stop ring is inserted. Accordingly, the lower end 724 of the rotating shaft 720 does not come out of the planetary rod 620 .

The pushing member 740 contacts the flange 722 of the rotating shaft 720 , and pushes the planetary driving gear 730 toward the planetary driving gear 710 and pushes the planetary driving gear 710 toward the planetary rod 620 . Thus, the pushing member 740 applies a load torque to the planetary drive gear 710 with respect to the planetary rod 620, so the driving force applied from the sun gear 612 to the planetary drive gear 710 is transmitted to the planetary rod 620, and the driving force is switched to The driving force to rotate the planetary rod 620. An example of the pushing member 740 is a coil spring.

In the above configuration, when a torque equal to or less than the reference value is applied between the planetary drive gear 710 and the planetary driven gear 730 , the planetary drive gear 710 and the planetary driven gear 730 rotate integrally. In addition, when a torque greater than the reference value is applied between the planetary drive gear 710 and the planetary driven gear 730, the inclined surface 734 of the planetary driven gear 730 moves along the planetary drive gear 710 against the pushing force of the pushing member 740. Sliding along the engaging ramp 714. As a result, the planetary driven gear 730 floats relative to the planetary drive gear 710 and freely rotates relative to the planetary drive gear 710 . Thus, the torque applied to the planetary driven gear 730 is limited. Thus, when a large torque is applied to the planetary driven gear 730 when the ink ribbon is tangled in the ink ribbon cassette 60 or the ink ribbon is locked, it is possible to prevent the ink ribbon winding unit 600 from being damaged. .

As described above, since the torque is restricted between the planetary driving gear 710 and the planetary driven gear 730 of the planetary gear 700 , there is no need to provide a torque limiting mechanism separately from the planetary gear 700 , and the number of parts can be reduced. Also, since the planetary driven gear 730 is pushed by the pushing member 740 in the above-mentioned order, even in the case where the planetary driven gear 730 freely rotates relative to the planetary drive gear 710, the meshing of the planetary drive gear 710 and the sun gear 612 can be maintained. . Furthermore, the torque as a reference value can be set by the inclination of the inclined surfaces 714 and 734 . For example, when the slopes 714 and 734 with small inclinations standing upright in the axial direction are provided, the reference value of the torque at which the planetary driven gear 730 starts to rotate freely with respect to the planetary drive gear 710 becomes large. In addition, when the slopes 714 and 734 are provided with a gentle slope and a large slope along the axial direction, the above-mentioned reference value of the torque becomes small. Moreover, in the present embodiment, the slopes 714, 734 are inclined symmetrically with respect to the rotation directions of the planetary drive gear 710 and the planetary driven gear 730, so when the planetary drive gear 710 and the planetary driven gear 730 rotate forward and reverse In the case of rotation, the reference value of the torque can be made the same. In addition, it should be noted that by making the inclinations of the slopes 714, 734 asymmetrical, the reference value of the torque can be set when the planetary drive gear 710 and the planetary driven gear 730 rotate forward and reverse. into different values.

As shown in FIG. 35 , the forward rotation driven gear 630 has a large-diameter gear portion 632 meshing with the planetary driven gear 730 , and is integrally formed with the large-diameter gear portion 632 above the large-diameter gear portion 632 and has a large diameter ratio. The diameter gear portion 632 is smaller than the small diameter gear portion 634 . The large-diameter gear portion 632 meshes with the planetary driven gear 730 when the planetary rod 620 rotates around the rotation shaft 242 when the sun gear 612 switches from reverse rotation to forward rotation. In addition, when the sun gear 612 reverses, the large-diameter gear portion 632 is out of mesh with the planetary driven gear 730 . The small-diameter gear portion 634 is constantly engaged with the ribbon winding shaft 660 . Therefore, when the large-diameter gear portion 632 rotates together with the planetary driven gear 730 , the small-diameter gear portion 634 transmits the rotational driving force to the ribbon winding shaft 660 to rotate the ribbon winding shaft 660 .

Similarly, the counter driven gear 640 has a large-diameter gear portion 642 that meshes with the planetary driven gear 730, is integrally formed with the large-diameter gear portion 642 above the large-diameter gear portion 642, and has a larger diameter than the large-diameter gear portion. 642 is a small diameter gear part 644 . The counter driven gear 640 meshes with the planetary driven gear 730 when the planetary rod 620 rotates around the rotation shaft 242 when the sun gear 612 switches from forward rotation to reverse rotation. In addition, when the sun gear 612 rotates forward, the large-diameter gear portion 642 is out of mesh with the planetary driven gear 730 . The small-diameter gear portion 644 always meshes with the intermediate gear 650 . Also, the intermediate gear 650 is always meshed with the ribbon winding shaft 660 . Therefore, the large-diameter gear portion 642 rotates with the planetary driven gear 730, and the small-diameter gear portion 644 transmits the rotational driving force to the intermediate gear 650, and the intermediate gear 650 further transmits the rotational driving force to the ribbon winding shaft 660, Rotate the ribbon take-up shaft 660.

Here, the large-diameter gear portion 632 of the positive rotation driven gear 630 and the large-diameter gear portion 642 of the counter driven gear 640 have a function even when the planetary driven gear 730 floats from the planetary drive gear 710 against the urging force of the urging member 740 . The height in the axial direction that also meshes with the planetary driven gear 730 in the raised state. Thus, even when the planetary driven gear 730 floats from the planetary driving gear 710 when receiving a torque equal to or greater than the reference value, it is possible to prevent the planetary driven gear 730 from colliding with the normal rotation driven gear 630 or the counter driven gear. The engagement of 640 is disengaged. Therefore, it is possible to smoothly return to the original position where the lower portion of the planetary driven gear 730 enters the planetary drive gear 710 .

The ribbon winding shaft 660 has a large-diameter gear portion 662 that is always meshed with the small-diameter gear portion 634 of the positive rotation driven gear 630 and the intermediate gear 650, and is smaller in diameter than the large-diameter gear portion 662, and is inserted into the ribbon cassette 60, and The reel fitting portion 664 of the ink ribbon cassette 60 fits. Thus, as described above, the sun gear 612 receives the rotational driving force from the forward rotation driven gear 630 when rotating forward, and receives the rotational driving force from the intermediate gear 650 when rotating reversely. In any case, the ribbon winding shaft 660 Both rotate in the same direction.

As shown in FIGS. 34 and 36 , the planetary rod bearing 672 of the housing 670 has a U-shaped cutout that contacts the protrusion 624 of the planetary rod 620 . As a result, the planetary rod 620 can smoothly and reliably rotate around the rotation shaft 242 relative to the housing 670 . Furthermore, since the notch 623 of the planetary lever 620 is arc-shaped, the ribbon winding unit 600 can be assembled more easily than when the planetary lever 620 is provided with a through hole and inserted into the rotating shaft 242 . Furthermore, since the sun gear 612 and the planetary lever 620 can be easily attached and detached, when the ribbon winding unit 600 breaks down, the ink ribbon winding unit 600 can be easily replaced. Furthermore, since the sun gear 612 is integrally formed with the belt drive pulley 610, there is no need to separately provide the sun gear 612 meshing with the belt drive pulley 610 to transmit the rotational driving force from the belt drive pulley 610, and the parts of the ribbon winding unit 600 can be reduced. quantity.

FIG. 38 is a plan view showing FIG. 37 , FIG. 39 is a left side view showing FIG. 38 , and FIG. 40 is a cross-sectional view showing A-A of FIG. 38 .

The motor 811 rotates the first cam 390 via a motor pinion 812 , a gear 813 , and a gear 814 . The rotation of the first cam 390 drives the above-mentioned following member 368 to move the correction plate 360 up and down ( FIGS. 4 , 12 , and 13 ). At the same time, the rotation of the first cam 390 actuates the first cam follower 817, the second cam 820, and the second cam follower 831, and through the end portion fixed to the second cam follower 831 The pushing pin 833 moves the object pressing portion 32 up and down. At this time, the second cam 820 opens and closes the movable paper guide 851 via the cam shaft 821 (see FIG. 41 ).

The recording device 10 according to this embodiment switches the postures of the correction plate 360 , the movable paper guide 851 , and the object pressing portion 32 according to the operating state. Hereinafter, the correction plate 360 , the movable paper guide 851 , and the recording object pressing portion 32 driven by the first cam 390 are referred to as a cam link mechanism. There are mainly three kinds of action states of the cam linkage mechanism, that is, the first state from inserting the object 100 to correct the skew, the second state when the object 100 is conveyed after the skew is corrected, and then the magnetic head 410 scans. The third state when the magnetic strip is 110.

41 and 42 are a side view and a perspective view showing the state of the cam link mechanism in the first state, respectively. In this figure, components other than the mechanism elements driven by the motor 811 are omitted for the sake of explanation. In the first state, the movable paper guide 851 enters the conveyance path of the object to be recorded 100 to support the object to be recorded 100 . The object pressing portion 32 avoids upward without hindering the movement of the object to be recorded 100 . In addition, the correction plate 360 enters a position that blocks the conveyance path of the object 100 to be recorded.

The first cam 390 is a disc-shaped cam member that rotates around the cam shaft 394 , and has cam grooves or cam ribs on both surfaces in the direction of the cam shaft 394 . In this embodiment, a pair of first cams 390 are arranged at both ends of the cam shaft 394, facing the recording device 10, the first cam 390 on the left side has a cam groove 392 on the inside, a cam auxiliary rib 391 on the outside, and the right The first cam 390 on the side has a cam groove 392 inside. The cam rib 391 is provided on the first cam 390 on the left side facing only the recording device 10 . The first cam 390 moves the correction plate 360 up and down by using the cam groove 392 provided on the inside, and moves the object pressing part 32 and the movable paper guide 851 by using the cam auxiliary rib 391 provided on the outside. In this way, by using the same first cam 390 to move the correction plate 360 , the object pressing portion 32 and the movable paper guide 851 , space saving and component cost reduction can be realized. In addition, since the cam link mechanism of this embodiment can be arranged along the left and right frames, the layout efficiency is high for the structure of the recording device 10 .

Hereinafter, a structure in which the first cam 390 moves the object pressing portion 32 and the movable paper guide 851 will be described. The cam follower pin 819 of the first cam follower 817 moves along the contour of the cam auxiliary rib 391 . Accordingly, the first cam follower 817 oscillates around the cam follower shaft 818 as the first cam 390 rotates forward and reverse. A gear provided on a part of the outer circumference of the first cam follower 817 meshes with a gear provided on a part of the second cam 820 . Therefore, the swing of the first cam follower 817 causes the second cam 820 to swing around the camshaft 821 . The cam shaft 821 is fixed to the second cam 820, and can transmit the swing of the second cam 820 to the second cam 822 fixed at the other end. One end of the second cam 822 is engaged with the movable paper guide 851 via a coil spring, and the movable paper guide 851 is opened and closed by the rotational force transmitted from the cam shaft 821 .

In addition, the second cam 820 and the second cam 822 have the same cam profile, and the left and right second cam followers 831 move up and down at the same time by swinging. On the upper portion of the object pressing portion 32 , a compression coil spring 836 pushes the object pressing portion 32 downward, wherein the upper end of the compression coil spring 836 is fixed on the frame of the front pressing portion 300 . At the end of the second cam follower 831 on the left and right, push pins 833 that push the two ends of the recording object pressing part 32 are fixed. As the second cam follower 831 rises, the recording pressing part 32 overcomes the pressure. The urging force of the coil spring 836 is compressed to rise. Accordingly, the pressing of the object to be recorded 100 by the object to be recorded pressing portion 32 is released.

Here, the cam link mechanism comprising the cam auxiliary rib 391, the first cam follower 817, the second cam 820, the second cam follower 831 and the pushing pin 833 is assembled so that the cam follower pin 819 is in the When the cam profile of the cam rib 391 is at the farthest position from the cam shaft 394, the object pressing portion 32 avoids upward from the transport path of the object 100, and the movable paper guide 851 enters the object 100. the delivery path.

When the cam follower pin 819 approaches the camshaft 394 along the cam rib 391 from this state, the above-mentioned cam link mechanism is interlocked to lower the recording object pressing part 32 to the conveyance path of the recording object 100 . At this time, the second cam 822 moves to avoid the movable paper guide 851 from the transport path of the object to be recorded 100 . The structure in which the correction plate 360 moves up and down by the rotation of the first cam 390 is as described in FIG. 11 , FIG. 12 , and FIG. 13 .

FIG. 43 is a diagram showing the relationship between the first cam 390 and the cam follower pin 819 in the first state on the left side. The cam auxiliary rib 391 has a swirl cam profile, and is located on the outermost circumference of the first cam 390 at about half a circle from the outermost peripheral end, and its front end gradually approaches the direction of the cam shaft 394 . Furthermore, the cam rib 391 is formed so as to be closest to the camshaft 394 after passing one turn from the outermost peripheral end.

The cam follower pin 819 swings so as to draw an arc-shaped track obliquely above the camshaft 394 . The cam follower pin 819 is located near the end of the outermost periphery of the cam auxiliary rib 391 as shown in the figure. It should be noted that, regarding the rotation of the first cam 390, the direction of the arrow in the figure is the positive direction. During the 1/2 rotation of the first cam 390 in the positive direction from the first state, the cam follower pin 819 is located at the farthest position obliquely above the camshaft 394 . Thereafter, when the first cam 390 further rotates in the forward direction, the cam follower pin 819 gradually moves toward the camshaft 394, that is, descends, and approaches the camshaft 394 after about one turn from the first state.

FIG. 44 is a diagram showing the relationship between the first cam 390 and the cam follower pin 398 in the first state. This figure corresponds to the opposite side showing the same posture as that of the first cam 390 shown in FIG. 43 . The cam groove 392 has a spiral cam profile, and is located on the outermost circumference of the first cam 390 at about half a circle from the end of the outermost circumference, and its front end gradually approaches the direction of the cam shaft 394 . Further, the cam groove 392 is formed so as to be closest to the cam shaft 394 after passing one turn from the outermost peripheral end. A wall-shaped stroke end portion 393 that contacts the cam follower pin 398 is formed at the end portion of the cam profile on the side closer to the camshaft 394 .

A cam follower pin 398 moves up and down below the camshaft 394 . In the first state, the cam follower pin 398 is located near the stroke end portion 393 , that is, at a position closest to the upper limit of the camshaft 394 . And as the first cam 390 rotates in the positive direction, the cam follower pin 398 moves toward the direction away from the camshaft 394, that is, descends, and reaches the farthest lower limit position from the camshaft 394 when it rotates about 1/2 turn. Afterwards, during a further 1/2 turn in the positive direction, the cam follower pin 398 is located at the lower limit position farthest from the camshaft 394 .

In the first state, both the cam follower pin 819 and the cam follower pin 398 are located at the upper limit positions of their movable ranges. When the first cam 390 rotates 1/2 turn in the positive direction from this state, the cam link mechanism of this embodiment changes to the second state.

45 and 46 are diagrams showing the relationship among the first cam 390, the cam follower pin 819, and the cam follower pin 398 in the second state. FIG. 46 corresponds to the opposite side showing the same posture as that of the first cam 390 shown in FIG. 45 . During the transition from the above-mentioned first state to the second state, the cam follower pin 819 is located at the upper limit of the movable range and does not move. On the other hand, the cam follower pin 398 gradually descends as the first cam 390 rotates, and reaches the lower limit of the movable range when it rotates about 1/2 turn from the first state.

Fig. 47 is a side view showing an example of the cam link mechanism in the second state. The position of the cam follower pin 819 does not change from the first position, and is at the position farthest from the camshaft 394 . Accordingly, the object pressing portion 32 avoids upward from the conveyance path of the object to be recorded 100 , and the movable paper guide 851 enters the conveyance path of the object to be recorded 100 .

On the other hand, the cam follower pin 398 is located at the lower limit position farthest from the camshaft 394 as shown in FIG. 46 , and presses the follower 368 and the pushing member 351 . Accordingly, the correction plate 360 avoids downward from the conveyance path of the object 100 to be recorded. When the first cam 390 further rotates 1/2 turn in the positive direction from this state, the cam link mechanism of this embodiment changes to the third state.

48 and 49 are diagrams showing the relationship among the first cam 390, the cam follower pin 819, and the cam follower pin 398 in the third state. FIG. 49 corresponds to the opposite surface showing the same posture as that of the first cam 390 shown in FIG. 48 . In the process of changing from the above-mentioned second state to the third state, the cam follower pin 819 descends slowly, and reaches the lower limit of the movable range when it rotates about 1/2 turn from the second state, that is, it reaches the closest to the camshaft 394. s position. During this period, the cam follower pin 398 is at the lower limit position of the movable range and does not move.

Fig. 50 is a side view showing an example of the cam link mechanism in the third state. Cam follower pin 819 is located closest to camshaft 394 . Thereby, the recording object pressing part 32 descends to the position where the recording object 100 abuts against the magnetic head 410, and the movable paper guide 851 avoids downward from the transport path of the recording object 100, and opens the scanning path of the magnetic head 410. .

On the other hand, the cam follower pin 398 is located at the lower limit position farthest from the camshaft 394 as shown in FIG. 49 , and presses the follower 368 and the pushing member 351 . Accordingly, the correction plate 360 avoids downward from the conveyance path of the object 100 to be recorded.

FIG. 51 is a timing chart showing the operations of the correction plate 360 , the object pressing portion 32 and the movable paper guide 851 . Through a series of operations in this time chart, the recording device 10 sequentially performs calibration, printing, and magnetic recording on the inserted object 100 , and finally ejects it.

In the standby state before the object to be recorded 100 is inserted, the pressure roller 310 and the transport roller 324 stop. In this standby state, the cam link mechanism of this embodiment is in the first state. That is to say, the correction plate 360 rises to the position of blocking the conveyance path of the object to be recorded 100, the object to be recorded pressing part 32 avoids to the upper side that does not hinder the movement of the object to be recorded on the part 32, and the movable paper guide 851 The scanning path of the magnetic head 410 is closed. In addition, since the pushing member 351 is located on the upper side, the pushing force of the pressure roller 310 is weak.

Here, the initial position setting of the first cam 390 is performed by rotating the motor 811 until the cam follower pin 398 hits the stroke end 393 shown in FIG. 44 , and rotating the first cam 390 until the motor 811 is disengaged. Accordingly, the end portion of the cam groove 392 can be reliably engaged with the cam follower pin 398 . In this case, since a detector for detecting the posture of the first cam 390 is unnecessary, cost reduction and miniaturization of the recording device 10 can be easily achieved.

When the recorded object 100 is inserted from the above-mentioned standby state, the pressure roller 310 and the conveying roller 324 rotate to convey the recorded object 100 while pinching it with a weak urging force. Then, after the front end of the object to be recorded 100 contacts the correction plate 360, the pressure roller 310 and the transport roller 324 are further rotated, so that the object to be recorded 100 is corrected.

After the object to be recorded 100 is calibrated, the first cam 390 rotates forward about 1/2 turn, and the cam link mechanism changes from the first state to the second state. That is, the pushing member 351 descends. Accordingly, the pushing force of the pressure roller 310 becomes stronger, and the object to be recorded 100 is sandwiched by the pressure roller 310 and the transport roller 324 with a strong force. In addition, in conjunction with the lowering of the pushing member 351 , the correction plate 360 is also lowered to avoid the conveyance path of the object to be recorded 100 . At this time, since the posture of the first cam follower 817 does not change from the first state, the object pressing portion 32 and the movable paper guide 851 are also in the same state as the first state. In this state, the pressure roller 310 and the transport roller 324 rotate in the normal direction, and the object to be recorded 100 is transported to the recording position. When the recording is completed, the object to be recorded 100 is conveyed to the magnetic reading and writing position by the reverse rotation of the pressure roller 310 and the conveyance roller 324 .

After the object to be recorded 100 is transported to the magnetic read/write position, the first cam 390 further rotates 1/2 turn forward. Accordingly, the cam link mechanism changes from the second state to the third state. That is to say, the recording object pressing part 32 descends to the position where the recording object 100 abuts against the magnetic head 410, the movable paper guide 851 avoids downward from the transport path of the recording object 100, and the scanning of the magnetic head 410 is opened. path. At this time, since the position of the pushing member 351 does not change from the second state, the position of the correction plate 360 and the pushing force of the pressure roller 310 also do not change from the second state. In this state, the magnetic head 410 scans the magnetic stripe 110 to read and write magnetic data.

After the magnetic head 410 scans the magnetic stripe 110, the first cam 390 rotates 1/2 turn in the reverse direction. Accordingly, the cam link mechanism changes from the third state to the second state. In other words, the object to be recorded pressing portion 32 releases the object to be recorded 100 and avoids upward. At the same time, the movable paper guide 851 rotates upwards to enter the transport path of the object 100 to be recorded, thereby closing the scanning path of the magnetic head 410 . At this time, since the position of the pushing member 351 does not change from the third state, the position of the correction plate 360 and the pushing force of the pressure roller 310 also do not change from the third state. In this state, the pressure roller 310 and the transport roller 324 rotate in reverse, and the object to be recorded 100 is discharged from the recording device 10 . Through the above operations, a series of operations in this time chart ends.

As can be seen from the above, when the first cam 390 rotates in the same direction, it starts to drive the correction plate 360 , the object pressing portion 32 , and the movable paper guide 851 at different timings. Thus, the load given to the motor 811 which is the power source is distributed. Accordingly, the motor 811 can be configured with a minimum size. In addition, the three conveying states formed by the combination of the states of the correction plate 360, the object pressing portion 32 and the movable paper guide 851 shown in FIG. The first state, the second state, and the third state), the cam link mechanism can be miniaturized. Accordingly, it is possible to provide a small and low-cost recording device 10 that reads and writes the magnetic stripe 110 with high precision.
