[0002]
[Prior art]
Conventionally, in a financial institution such as a bank, a passbook slip printer is connected to an online terminal, and printing is performed on a medium such as a passbook or slip by the passbook slip printer.
2 is a perspective view of a conventional passbook slip printer, FIG. 3 is a view showing the internal structure of the conventional passbook slip printer, and FIG. 4 is a view showing the periphery of the print head of the conventional passbook slip printer.
[0003]
In the figure, 101 is a main body of a passbook slip printer, 102 is an insertion slot for inserting a passbook (not shown), 103 is an insertion slot for inserting a slip (not shown), and 104 conveys a medium 109 such as the passbook or slip. A plurality of conveying roller pairs 105, which are disposed at the junctions of the conveying paths a1 to a3 of the medium 109, and blades for selectively connecting the conveying paths a1 and a3 and the conveying paths a2 and a3; 106 is a print head for printing characters, numbers, symbols, etc. on the medium 109, 107 is a platen for pressing the medium 109 against the tip of the print head 106, and 108 is fixed to the print head 106, and the print head 106 , 110a and 110b are guides for guiding the medium 109. .
[0004]
In the passbook slip printer configured as described above, when the medium 109 is inserted into the insertion ports 102 and 103, a series of processing of the passbook slip printer is automatically started. When the medium 109 is conveyed by the conveyance roller pair 104 and is sent to a portion where printing is performed on the medium 109, that is, a position where the print position is opposed to the tip portion of the print head 106, the state shown in FIG. Become.
[0005]
As shown in the figure, the guide surface S1 for guiding the medium 109 of the protector 108 is slightly protruded into the transport path a3 from the guides 110a and 110b, and slightly transported from the front end portion of the print head 106. Since it is positioned on the a3 side, a slight gap is formed between the surface of the medium 109 that passes therethrough and the front end portion of the print head 106.
[0006]
In this state, when printing is performed, the platen 107 is moved forward (moved upward in FIG. 4), and the medium 109 is pressed against the tip portion of the print head 106. The conveyance roller pair 104 is stopped while printing is being performed. However, when printing for a plurality of lines on the medium 109, the conveyance roller pair 104 is intermittently linked to the operation of the print head 106. The medium 109 is conveyed one line at a time.
[0007]
When printing is completed, the platen 107 is moved backward (moved downward in FIG. 4), the conveyance roller pair 104 resumes rotation, and the medium 109 is conveyed rightward in FIG. It is discharged out of the main body 101.

There is a gap between them. As described above, the guide surface S1 is slightly protruded into the transport path a3 from the guides 110a and 110b.
[0010]
Therefore, when the medium 109 passes through the gap, the front end of the medium 109 is easily locked to the side end surface S2 of the protector 108, and the medium 109 is wrinkled when the front end of the medium 109 is locked to the side end surface S2. In the worst case, the medium 109 cannot be removed while being locked in the gap, and a paper jam occurs, that is, a jam occurs.
[0011]
Further, even when the medium 109 that has passed through the print head 106 hits the end P1 of the guide 110b on the print head 106 side, the print position changes due to wrinkles on the medium 109 or the amount of conveyance of the medium 109 changes. Or cause jamming.

[0021]
In the figure, 16 is a print head, 20 is a sensor, 30 is a main control unit, 31 is a medium transport control unit, 32 is a pulse motor, 34 is a print control unit, 35 and 45 are magnetic head control units, and 36 and 46 are magnetic. Head.
In the passbook slip printer configured as described above, when the medium 22 (FIG. 1) is inserted into either the insertion slot 12 (FIG. 5) or 13, the series of processing of the passbook slip printer is automatically performed by the main control unit 30. Be started. In response to the command from the main control unit 30, the medium conveyance control unit 31 drives the pulse motor 32.
[0022]
At this time, the protector 18 is rotated by the urging force of the urging means, and the guide surface S1 is inclined at a predetermined inclination angle with respect to the conveyance path a3. In the present embodiment, the inclination angle is set to about 5 [°] with respect to the transport path a3.
The medium 22 is transported along the transport paths a1 and a2 by the transport roller pair 14 driven by the pulse motor 32, and then transported to the transport path a3.
[0023]
Next, when the medium 22 passes through the magnetic head 36 disposed in front of the print head 16, data written in the magnetic stripe formed on the medium 22 is read by the magnetic head 36. The read data is sent to the main control unit 30 via the magnetic head control unit 35.
Next, when the end of the medium 22, that is, the front end (the right end in FIG. 1) reaches the position of the sensor 20, the sensor 20 detects the medium 22 and sends the detection signal via the medium transport control unit 31. The data is sent to the control unit 30. When the main control unit 30 receives the detection signal, the main control unit 30 starts control for printing processing.
[0024]
Therefore, the main control unit 30 starts counting the number of pulses sent to the pulse motor 32 for driving the conveying roller pair 14 from the time when the detection signal is received, and the count value becomes a set value. When the print position on the medium 22 is sent to a position facing the tip portion of the print head 16, the pulse motor 32 is stopped. In this way, the print position of the medium 22 is determined.
[0025]
When the printing position adjustment is completed, the platen 17 is advanced to press the medium 22 against the tip portion of the print head 16. As a result, the protector 18 is pushed by the platen 17, is rotated counterclockwise in FIG. 7, and is made parallel to the transport path a3.
In this state, characters, numbers, symbols, and the like are printed on the medium 22 by the print head 16, and printing processing is performed.
[0026]
The transport roller pair 14 is stopped while printing is being performed. However, when a plurality of lines are printed on the medium 22, it is intermittently rotated in conjunction with the operation of the print head 16. The medium 22 is conveyed one line at a time.
Subsequently, when the printing process is completed, the platen 17 is retracted. At this time, the protector 18 is rotated clockwise in FIG. 7 by the urging force of the urging means and placed in the state shown in FIG.
[0027]
Next, the conveyance roller pair 14 resumes rotation, and the medium 22 is further conveyed along the conveyance path a3 and discharged out of the main body 11 from the discharge port 41 (FIG. 6).
In the middle of the discharge, when the medium 22 passes through the magnetic head 46 disposed on the discharge port 41 side from the print head 16, data is written to the magnetic stripe of the medium 22 by the magnetic head 46.
[0028]
In the case of a passbook slip printer in which the medium 22 can be discharged from the insertion ports 12 and 13, the transport roller pair 14 is rotated in the reverse direction, and the medium 22 is transported from the transport path a3 to the transport path a1. , A <b> 2 are conveyed and discharged from the insertion ports 12 and 13. In the case of this type of passbook slip printer, data is written to the magnetic stripe of the medium 22 by the magnetic head 36. In this case, in general, the medium 22 on which printing has been completed once (once) passes completely through the print head 16, and after the rear end of the medium 22 has moved away from the print head 16, the transport roller pair 14 is reversed. Rotated.
[0029]
Thus, in the present embodiment, the protector 18 is urged by the urging means, and the guide surface S1 is inclined with respect to the transport path a3 and is directed to the front end of the medium 22. When the front end of 22 passes through the gap between the guide 23 and the protector 18, the front end of the medium 22 is not locked to the side end surface S <b> 2 of the protector 18. Therefore, the medium 22 is not wrinkled, the conveyance amount of the medium 22 is not changed, and the actual printing position is not changed, or a jam is not caused.
[0030]
Further, since the medium 22 is curved toward the platen 17 along the guide surface S1 when passing through the print head 16, the medium 22 does not hit the end 23a of the guide 23.
Next, a flowchart will be described.
Step S1: The medium 22 is inserted.
Step S2: Read the magnetic stripe data of the medium 22.
Step S3 Print position is determined.
Step S4 Print processing is performed.
Step S5: Write data to the magnetic stripe.
Step S6: The medium 22 is discharged.
[0031]
Next, a second embodiment of the present invention will be described.
FIG. 10 is a control block diagram of the passbook slip printer according to the second embodiment of the present invention. In addition, about what has the same structure as 1st Embodiment, the description is abbreviate | omitted by providing the same code | symbol.
In this case, the protector 18 (FIG. 1) is rotated by driving a protector rotating solenoid 33 serving as a protector rotating means.
[0032]
When the medium 22 is inserted into one of the insertion ports 12 (FIG. 5) and 13, a series of processing of the passbook slip printer is automatically started by the main control unit 30. Next, upon receiving a command from the main control unit 30, the medium transport control unit 31 drives the pulse motor 32 and the protector rotating solenoid 33.
With the start of a series of processes by the main control unit 30, the protector 18 is rotated clockwise by a protector rotating solenoid 33, as shown in FIG. 1, and the guide surface S1 is a predetermined distance with respect to the transport path a3. It is inclined at an inclination angle.
[0033]
The medium 22 is transported to transport paths a1 and a2 by a transport roller pair 14 as transport means driven by a pulse motor 32. Then, when the medium 22 passes through the magnetic head 36 disposed in front of the print head 16, data written in the magnetic stripe of the medium 22 is read by the magnetic head 36. The read data is sent to the main control unit 30 via the magnetic head control unit 35.
[0034]
When the front end (right end in FIG. 1) of the medium 22 reaches the position of the sensor 20, the sensor 20 detects the medium 22 and sends a detection signal to the main control unit 30 via the medium transport control unit 31. . When the main control unit 30 receives the detection signal, the main control unit 30 starts control for printing processing. That is, the main control unit 30 starts counting the number of pulses sent to the pulse motor 32 for driving the conveying roller pair 14 from the time when the detection signal is received, and the count value becomes a set value. When the print position on the medium 22 is sent to a position facing the tip portion of the print head 16, the pulse motor 32 is stopped and the print position of the medium 22 is determined.
[0035]
When the printing position of the medium 22 is determined, the main control unit 30 drives the protector rotating solenoid 33 so that the protector 18 is parallel to the transport path a3 as shown in FIG. Put on. In this embodiment, the protector rotating solenoid 33 is driven to place the protector 18 in a state parallel to the transport path a3. However, the protector 18 is moved by a biasing force such as a return spring. 18 can also be placed in a state parallel to the transport path a3.
[0036]
Then, the platen 17 is moved forward (moved upward in FIG. 7), and the medium 22 is pressed against the front end portion of the print head 16, and in this state, the print head 16 converts characters, numbers, symbols, and the like into the medium. 22 is printed, and the printing process is performed.
The transport roller pair 14 is stopped while printing is being performed. However, when a plurality of lines are printed on the medium 22, it is intermittently rotated in conjunction with the operation of the print head 16. The medium 22 is conveyed one line at a time.
[0037]
Subsequently, when the printing process is completed, the platen 17 is retracted, the conveyance roller pair 14 resumes rotation, and the medium 22 is further conveyed along the conveyance path a3 and is moved out of the main body 11 from the discharge port 41 (FIG. 6). Discharged.
In the middle of the discharge, when the medium 22 passes through the magnetic head 46 disposed on the discharge port 41 side from the print head 16, data is written to the magnetic stripe of the medium 22 by the magnetic head 46.
[0038]
Thus, in the present embodiment, when the front end of the medium 22 passes through the gap between the guide 23 and the protector 18, the protector rotating solenoid 33 is driven to rotate the protector 18, and the guide surface S1 is moved. Since it is inclined with respect to the transport path a3 and is directed to the front end of the medium 22, the front end of the medium 22 is not locked to the side end surface S2 of the protector 18. Therefore, the medium 22 is not wrinkled, the conveyance amount of the medium 22 is not changed, and the actual printing position is not changed, or a jam is not caused.
[0039]
Further, since the medium 22 is curved toward the platen 17 along the guide surface S1 when passing through the print head 16, the medium 22 does not hit the end portion 23a of the guide 23.
Incidentally, since the passbook slip printer handles the passbook, it is often equipped with a page turning device for page breaks.
[0040]
Next, a third embodiment of the present invention provided with a page turning apparatus will be described.
FIG. 11 is a control block diagram of the passbook slip printer in the third embodiment of the present invention. In addition, about the thing which has the same structure as 2nd Embodiment, the description is abbreviate | omitted by providing the same code | symbol.
[0041]
In this case, the page turning device 40 is disposed on the insertion port 12 (FIG. 5) or 13 side or the discharge port 41 (FIG. 6) side from the print head 16 in the transport path a3 (FIG. 1), and is used for main control. The page of the passbook as the medium 22 is turned by the instruction of the unit 30.
When the page turning device 40 is disposed closer to the discharge port 41 than the print head 16, the passbook that has finished printing a certain page passes completely through the print head 16 in the transport path a3, and the page After being sent to the page turning device 40 and the page turning is performed in the page turning device 40, the page turning device 40 is conveyed toward the insertion ports 12 and 13 side. Then, the passbook is stopped when it completely passes through the print head 16 and the front end of the passbook (the right end in FIG. 1) is separated from the print head 16, and then the transport path a3 is directed again toward the discharge port 41. The next page is printed.
[0042]
At this time, the protector 18 is rotated, and the guide surface S1 is inclined at a predetermined inclination angle with respect to the transport path a3.
As described above, in the present embodiment, when the front end of the bankbook passes through the gap between the guide 23 and the protector 18, the protector rotating solenoid 33 as the protector rotating means is driven to rotate the protector 18. Since the guide surface S1 is inclined with respect to the transport path a3 and directed toward the front end of the bankbook, the front end of the bankbook is not locked to the side end surface S2 of the protector 18. Therefore, there is no wrinkling of the bankbook, no change in the carrying amount of the bankbook, and no change in the actual printing position or jamming.
[0043]
Further, since the bankbook is curved toward the platen 17 along the guide surface S1 when passing through the print head 16, the bankbook does not hit the end 23a of the guide 23.
Next, a fourth embodiment of the present invention will be described.
FIG. 12 is a diagram showing a first state of the protector according to the fourth embodiment of the present invention, FIG. 13 is a diagram showing a second state of the protector according to the fourth embodiment of the present invention, and FIG. The figure which shows the 3rd state of the protector in 4th Embodiment of this invention, FIG. 15 is a control block diagram of the passbook slip printer in the 4th Embodiment of this invention, FIG. 16 is 4th Embodiment of this invention. It is a flowchart which shows the operation | movement of the passbook slip printer in the form. In addition, about the thing which has the same structure as 3rd Embodiment, the description is abbreviate | omitted by providing the same code | symbol.
[0044]
In this case, a first sensor 51 is disposed on the insertion port 12 (FIG. 5) and 13 side from the print head 16 in the conveyance path a3, and a second sensor 52 is disposed on the discharge port 41 (FIG. 6) side. The passbook as the medium 22 is detected by the first and second sensors 51 and 52. The first and second sensors 51 and 52 can be optical, contact type or the like.
[0045]
Next, the operation of the passbook slip printer having the above configuration will be described.
When a passbook is inserted into one of the insertion ports 12 and 13, a series of processing of the passbook slip printer is automatically started by the main control unit 30. In response to the command from the main control unit 30, the medium conveyance control unit 31 drives the pulse motor 32 and the protector rotating solenoid 33 as the protector rotating means.
[0046]
With the start of a series of processes by the main control unit 30, the protector 18 is rotated clockwise by the protector rotating solenoid 33, as shown in FIG. 12, and the guide surface S1 is a predetermined distance with respect to the transport path a3. It is inclined at an inclination angle.
The bankbook is transported along transport paths a1 and a2 by a transport roller pair 14 serving as transport means driven by a pulse motor 32, and then transported to a transport path a3.
[0047]
Next, when the passbook passes through the magnetic head 36 disposed in front of the print head 16, the data written in the magnetic stripe of the passbook is read by the magnetic head 36. The read data is sent to the main control unit 30 via the magnetic head control unit 35.
Next, when the front end of the bankbook (the right end in FIG. 12) reaches the position of the first sensor 51, the first sensor 51 detects the bankbook and controls the detection signal via the medium conveyance control unit 31. Send to part 30. When the main control unit 30 receives the detection signal, the main control unit 30 starts control for printing processing.
[0048]
Therefore, the main control unit 30 starts counting the number of pulses sent to the pulse motor 32 for driving the conveying roller pair 14 from the time when the detection signal is received, and the count value becomes a set value. When the printing position on the bankbook is sent to a position facing the front end portion of the print head 16, the pulse motor 32 is stopped. In this way, the printing position of the passbook is determined.
[0049]
The protector rotating solenoid 33 can also be driven at this time. That is, when the first sensor 51 detects the bankbook, the protector 18 can be rotated to incline the guide surface S1 with respect to the transport path a3 at a predetermined inclination angle.
When the passbook print position is determined, the main control unit 30 drives the protector rotating solenoid 33 so that the protector 18 is parallel to the transport path a3 as shown in FIG. Put. In this embodiment, the protector rotating solenoid 33 is driven to place the protector 18 in a state parallel to the transport path a3. However, the protector 18 is moved by a biasing force such as a return spring. 18 can also be placed in a state parallel to the transport path a3.
[0050]
Then, the platen 17 is moved forward (moved upward in FIG. 13), and the passbook is pressed against the tip of the print head 16, and in this state, characters, numbers, symbols, etc. are transferred to the passbook by the print head 16. Printing is performed and printing processing is performed.
The transport roller pair 14 is stopped while printing is being performed. However, when a plurality of lines are printed on the passbook, the transport roller pair 14 is intermittently rotated in conjunction with the operation of the print head 16. The bankbook is conveyed line by line.
[0051]
Subsequently, when the printing process is completed, the platen 17 is retracted (moved downward in FIG. 13), the conveyance roller pair 14 resumes rotating, and the bankbook is further conveyed along the conveyance path a3. Then, after the passbook has completely passed through the print head 16 and the rear end of the passbook (the left end in FIG. 13) has moved away from the print head 16, the passbook is sent to the page turning device 40. After being performed, the transport path a3 is transported toward the insertion ports 12 and 13 side.
[0052]
On the other hand, when the rear end of the passbook reaches the position of the second sensor 52, the passbook is detected by the second sensor 52, and a detection signal of the passbook is sent to the main control unit 30 via the medium conveyance control unit 31. It is done. At this time, as shown in FIG. 14, the main control unit 30 rotates the protector 18 counterclockwise by the protector rotating solenoid 33, and the guide surface S1 with a predetermined inclination angle with respect to the transport path a3. Tilt.
[0053]
The passbook is stopped when it completely passes through the print head 16 and the front end of the passbook (the right end in FIG. 14) is separated from the print head 16, and then the transport path a3 is directed again toward the discharge port 41. Then, the next page is printed.
Thus, when the printing process is completed for all pages, the conveyance roller pair 14 is rotated in the reverse direction, and the bankbook is conveyed toward the insertion ports 12 and 13 along the conveyance path a3.
[0054]
Thus, in this embodiment, when the passbook reciprocates the print head 16, when the front end of the passbook passes through the gap between the guide 23 and the protector 18, the protector rotating solenoid 33 is driven and the protector 18 is moved. Since the guide surface S1 is rotated and tilted at a predetermined angle in both directions with respect to the transport path a3, the front end of the bankbook is not locked to the side end surfaces S2 and S3 of the protector 18. Therefore, there is no wrinkling of the bankbook, no change in the carrying amount of the bankbook, and no change in the actual printing position or jamming.
[0055]
Further, since the bankbook is curved toward the platen 17 along the guide surface S1 when passing through the print head 16, the bankbook does not hit the end portions 23a and 23b of the guide 23.
Next, a flowchart will be described.
Step S11 Insert a bankbook.
Step S12: Read the magnetic stripe data of the bankbook.
Step S13: Print position is determined.
Step S14 Print processing is performed.
Step S15: It is determined whether or not to perform a page break. If a page break is to be performed, the process proceeds to step S16. If no page break is to be performed, the process proceeds to step S18.
Step S16: Perform page break.
Step S17: It is determined whether the page break is completed. If the page break is completed, the process proceeds to step S18. If the page break is not completed, the process returns to step S16.
Step S18: Write data to the magnetic stripe.
Step S19: The bankbook is discharged.
[0056]
In addition, this invention is not limited to the said embodiment, It can change variously based on the meaning of this invention, and does not exclude them from the scope of the present invention.

As described above in detail, according to the present invention, in the passbook slip printer, the transport means for transporting the medium, the print head that is disposed in the transport path of the medium and performs printing on the medium, A guide that is disposed at least on the print head side in the transport path and guides the medium in the vicinity of the print head; Cover the substantially tip portion of the print head, centering on a fulcrum set at a predetermined location of the tip portion of the print head A protector that is supported in a swingable manner, protects the tip portion of the print head, and has a guide surface for guiding the medium, and rotates the protector so that the guide surface is inclined with respect to the transport path. , And a protector rotating means for directing the end of the medium passing through the gap between the guide and the print head.
[0058]
In this case, when the end of the medium passes through the gap between the guide and the protector, the guide surface of the protector is inclined and directed toward the end of the medium, so that the front end or the rear end of the medium is related to the side end surface of the protector. There is no stopping. Therefore, there is no wrinkling of the medium, and the actual printing position does not change due to a change in the conveyance amount of the medium or a jam occurs.
[0059]
Further, since the medium is curved toward the platen side along the guide surface when passing through the print head, the medium does not hit the end of the guide on the print head side.
