[Ink cartridge insertion]
Next, the operation will be described separately for each state of insertion, loading, and ejection of the ink cartridge 211.
First, the ink cartridge 211 is inserted into the insertion opening 271 from the state where the ink cartridge 211 shown in FIG. At this time, a guide surface 363d is provided on the lever projection 363c of the knob portion 363a formed on the distal end side of the arm main body 363b of the lever arm 363, and the guide surface 363d allows the user to insert the ink cartridge 211 into the opening. The ink cartridge 211 is provided to guide the insertion opening 271 when the ink cartridge 211 is inserted into the insertion opening 271. Specifically, the guide surface 363d is an ink cartridge so that the ink cartridge 211 protruding from the entry path A extending in the direction facing the insertion opening 271 is gradually pushed back to the entry path A as it approaches the insertion opening 271. Inclined with respect to the loading direction 211.
Here, the “loading direction” refers to a direction in which the ink cartridge 211 enters the insertion opening 271 toward the ink supply needle 411 at the back. Specifically, it is a direction from the lower side to the upper side indicated by the arrow in FIG.

When the leading end side of the ink cartridge 211 is inserted into the insertion opening 271, the leading end of the ink cartridge 211 hits the discharge lever 385 provided at the back of the insertion opening 271. The discharge lever 385 is provided so as to rotate about the discharge lever shaft 386 as a fulcrum and to be urged in a discharge direction in which the ink cartridge 211 is discharged by a spring (not shown).
Here, the “discharge direction” refers to a direction opposite to the loading direction.

  And the state which stopped for a while is a state shown in FIGS. In this state, since the side surface of the ink cartridge 211 blocks the trajectory of the lever protrusion 363c, the lever arm 363 at the “reset position” cannot be rotated to the “set position” side. Therefore, an operation in which the user pushes the ink cartridge 211 in the loading direction with the lever protrusion 363c, that is, a so-called erroneous operation (abnormal operation) can be prevented.

FIG. 8 is a plan view showing the attachment / detachment device of the “reset position” of the lever arm when the ink cartridge is completely inserted, and FIG. 9 is a side perspective view of FIG. 10 shows a cross-sectional side view of the main part of FIG.
When the ink cartridge 211 is further pushed in against the urging force of the discharge lever 385 from the state shown in FIGS. 5 to 7 and inserted for the first predetermined stroke S1, insertion of the ink cartridge 211 shown in FIGS. 8 to 10 is completed. It becomes a state.

  Specifically, when the ink cartridge 211 is further pushed in from the states shown in FIGS. 5 to 7, the leading end portion of the ink cartridge 211 protrudes downward through the second slider opening portion 247 of the slider portion 240. It comes into contact with 250 claw portions 251 and 251. The leading end of the ink cartridge 211 pushes up the claw portions 251 and 251 against the urging force of the latch plate spring 256, and the two claw portions 251 and 251 and the two concave portions 211a and 211a on the ink cartridge side. And engage. That is, the slider portion 240 integrally holds the ink cartridge 211 via the latch plate 250. This state is a state where the ink cartridge 211 is completely inserted.

  Note that the two claw portions 251 and 251 of the latch plate 250 are formed integrally with the latch plate 250. The two claw portions 251 and 251 of the latch plate 250 are provided so as to engage with the two concave portions 211 a and 211 a provided at substantially the center in the width direction with respect to the loading direction of the ink cartridge 211. . Therefore, even if the orientation of the ink cartridge 211 is inclined to some extent with respect to the loading direction, the two claw portions 251 and 251 can engage with the two concave portions 211a and 211a. Further, since the two claw portions 251 and 251 are synchronized by being formed integrally, only one of them engages with the recesses 211a and 211a, and the other does not engage with the recesses 211a and 211a, so-called There is no risk of one-side latching.

  8 to 10, even if the ink cartridge 211 is pushed by hand further from the position of the ink cartridge 211 shown in FIGS. 8 to 10, the tip side of the ink cartridge 211 is restricted by the contact portion 243 provided in the slider portion 240. Is done. At this time, the slider portion 240 is provided so as not to move unless the lever arm 363 is rotated by the shape of the cam portion 235 (see FIG. 25) described later.

[Loading ink cartridges]
FIG. 11 is a plan view showing the attachment / detachment device in the middle of loading of the ink cartridge, and FIG. 12 is a sectional side view of the main part of FIG.
As shown in FIG. 11, when the lever arm 363 is rotated counterclockwise from the “reset position” shown in FIG. 8 with the lever support shaft 364 as a fulcrum, the first gear 231 moves to the second gear 232 as described above. Power is transmitted, and a third gear 233 provided integrally with the second gear 232 transmits power to the fourth gear 234. A cam portion 235 provided integrally with the fourth gear 234 contacts and presses the first surface 246a of the first slider opening 246 to move the slider portion 240 in the loading direction. At this time, guide slits 241a and 241b are provided in the slider portion 240 at two locations in series along the loading direction. Then, shafts 262a and 262b provided on the base 387 are inserted into the guide slits 241a and 241b, whereby the moving direction of the slider portion 240 is restricted.

  At this time, the cam portion 235 is configured to press the central portion in the width direction with respect to the loading direction of the slider portion 240. Further, regarding the positional relationship with the latch plate 250, the position of the cam portion 235 where the slider portion 240 is pressed is the position on the approximate center line of the two claw portions 251, 251 of the latch plate 250 in the width direction. It is comprised so that. Furthermore, as shown in FIG. 12, the surfaces of the claw portions 251 and 251 that press the ink cartridge 211 are provided so as to be orthogonal to the loading direction. Accordingly, the postures of the ink cartridge 211, the latch plate 250, and the slider portion 240 can be stabilized, and the power of the cam portion 235 can be efficiently transmitted to the ink cartridge 211.

  When the slider portion 240 moves in the loading direction, the ink cartridge 211 held by the claw portions 251 and 251 of the latch plate 250 also moves together. At this time, due to the weight of the ink cartridge 211, the engagement between the slider engaging portion 245 as the first engaging means and the latch plate engaging portion 254 is loosened, and in the second engaging means, the latch plate slit 255 and The engaging slider protrusion 242 presses the surface of the latch plate slit 255 on the loading direction side. This pressing force moves the ink cartridge 211 in the loading direction via the claw portions 251 and 251. As the ink cartridge 211 moves, the ink supply needle 411 provided on the leading end side in the loading direction gradually pierces the ink cartridge 211.

  At this time, in order to pierce the ink supply needle 411 into the ink cartridge 211, a large pressing force is required. Therefore, since the slider protrusion 242 is provided by bending in a direction orthogonal to the loading direction as described above, there is no possibility of bending or deformation even when a large force is applied. That is, the slider protrusion 242 can be in surface contact with the surface of the latch plate slit 255 on the loading direction side and reliably transmit the pushing force to the ink cartridge 211 via the latch plate 250. Further, since the slider protrusion 242 is not deformed, the position of the latch plate 250 can be determined with high accuracy, so-called rigid.

  The reason why the latch plate 250 is engaged with the slider portion 240 by the first engagement means and the second engagement means in this manner is that if a support shaft is provided to swing the latch plate 250, When the ink cartridge 211 is loaded, a large pressing force necessary for loading the ink cartridge 211 is concentrated on the support shaft, and the support shaft may be deformed, so that the accuracy of the pressing force and the pressing distance when the ink cartridge 211 is pressed may not be ensured. This is because it occurs. Therefore, by changing the engagement position by the operation of the latch plate 250 without providing the support shaft, the pushing force and the pushing distance (second predetermined stroke S2) can be surely provided with the swing function of the latch plate 250 being provided. ) Can be secured.

  Furthermore, the slider engaging portion 245 and the latch plate engaging portion 254 as the first engaging means, and the slider protrusion 242 and the latch plate slit 255 as the second engaging means are provided to the claw portions 251 and 251. Therefore, the positions of the claw portions 251 and 251 of the latch plate 250 can be determined more accurately and rigidly. Further, since the pair of the first engaging means and the second engaging means are provided in the width direction with respect to the loading direction, the posture of the latch plate 250 can be stabilized. Furthermore, since the second engaging means is provided in series with the claw portions 251 and 251 in the loading direction, the pushing force can be transmitted to the claw portions 251 and 251 more efficiently. .

  Further, the slider protrusion 242 and the latch plate slit 255 of the second engagement means regulate the position of the latch plate 250 in the width direction with respect to the slider portion 240. Therefore, when the ink cartridge 211 is inserted, the concave portions 211a and 211a of the ink cartridge 211 and the claw portions 251 and 251 of the latch plate can be reliably opposed to each other.

  The positions where the claw portions 251 and 251 engage with the recesses 211a and 211a are closer to the position where the ink supply needle 411 sticks into the ink cartridge 211 in the height direction of the ink cartridge 211 (the vertical direction in FIG. 12). In addition, the posture of the ink cartridge 211 can be stabilized, and the pushing force, which is the power of the cam portion 235 at the time of loading, can be efficiently transmitted to the ink cartridge 211. Although there is a relationship with the trajectory of the lower end of the claw portions 251 and 251 when the latch plate 250 swings upward at the time of ejection described later, the engagement positions of the claw portions 251 and 251 and the recesses 211a and 211a are as follows. In the height direction of the ink cartridge 211, it is desirable that the ink supply needle 411 is disposed in a positional relationship.

  When the lever arm 363 is continuously rotated to the “set position” side, the shoulder portion 252 provided on the slider portion 240 is brought into contact with the tip of the cancel arms 260a and 260b as the slider portion 240 moves in the loading direction. Abutting on the portion 260c, the cancel arms 260a and 260b are rotated against the urging force of the cancel arm spring 261 with the shaft 262c inserted through the slit 241c and the shaft 262a inserted through the guide slit 241a as fulcrums, respectively. (See FIG. 11). At this time, since the shoulder portion 252 receives a pressing force from the tip contact portion 260c, the contact between the slider protrusion 242 and the surface of the latch plate slit 255 on the loading direction side can be further ensured. That is, the posture of the latch plate 250 can be stabilized by the biasing force of the cancel arm spring 256.

Further, when the slider portion 240 moves in the loading direction and the shoulder portion 252 passes the tip contact portion 260c of the cancel arms 260a and 260b, the cancel arms 260a and 260b are returned to the original state by the urging force of the cancel arm spring 261. Return to FIG. 5, FIG. 8, and FIG. The cancel arms 260a and 260b are members that act on the latch plate 250 when the ink cartridge 211 is discharged, and will be described later.
When the lever arm 363 is rotated counterclockwise and operated to the “set position”, the ink cartridge 211 is completely loaded.

FIG. 13 is a front perspective view showing the attachment / detachment device in which the ink cartridge is completely loaded and the lever arm is in the “set position”. FIG. 14 is a plan view of FIG. 13 and FIG. FIG. 13 is a side perspective view of FIG. 13, and FIG. 16 is a side sectional view of the main part of FIG.
As shown in FIGS. 13 to 16, when the lever arm 363 is further rotated from the state of FIGS. 11 and 12 to the “set position”, the ink cartridge 211 is inserted into the ink cartridge 211 (FIGS. 8 to 8). 10), the ink supply needle 411 is completely stuck into the ink cartridge 211, that is, the ink cartridge 211 is completely loaded.

Further, immediately before the ink cartridge 211 is completely loaded, the ink remaining amount information terminal 212 provided on the front right side surface of the ink cartridge 211 is electrically connected to the connector portion 412 provided on the attachment / detachment apparatus main body side. Is provided. The connector portion 412 is provided so as to be movable by a fixed distance in the loading direction, and the ink cartridge 211 is completely loaded by the contact surface that contacts the tip side surface of the ink cartridge 211 and the connector spring 413 on the leading end side of the connector portion 412 in the loading direction. The ink cartridge 211 is provided so as to be able to follow the movement of the ink cartridge 211 for a slight stroke from immediately before the completion of loading.
Note that friction occurs between the connector portion 412 and the ink cartridge 211 when the connector portion 412 is electrically connected to the ink remaining amount information terminal 212 and when the connection is released.

  Furthermore, immediately before the completion of the loading of the ink cartridge 211, the front end side of the ink cartridge 211 has a valve lever (not shown) for switching opening and closing of an ink flow path valve (not shown) provided on the attachment / detachment apparatus main body side. Abut. The valve lever is provided so as to urge the ink cartridge 211 in the discharge direction by a spring (not shown) in the same manner as the discharge lever 385. When the front end side of the ink cartridge 211 is not in contact with the valve lever, the ink flow path valve is in a closed state. On the other hand, when the ink cartridge 211 is completely loaded, the front end side of the ink cartridge 211 comes into contact with the valve lever and is biased. When the valve lever is moved against this, the ink flow path valve is opened.

[Eject ink cartridge]
FIG. 17 is a plan view showing the attachment / detachment device in the middle of discharging the ink cartridge, and FIG. 18 is a sectional side view of the main part of FIG.
When the ink cartridge 211 is discharged, the lever arm 363 is rotated clockwise from the “set position” shown in FIG. 13 to the “reset position” shown in FIGS. 5 and 8. At this time, since the operation of the attachment / detachment device 201 is complicated, it will be described below in stages.

  As shown in FIGS. 17 and 18, when the lever arm 363 is slightly rotated from the “set position” to the “reset position” side, the rotation power of the lever arm 363 is transmitted to the cam portion 235 as described above. . The cam portion 235 contacts and presses the second surface 246b of the first slider opening 246 provided in the slider portion 240, and slightly moves the slider portion 240 in the discharge direction. At this time, since the ink supply needle 411 is pierced, the ink cartridge 211 does not move until it comes into contact with the contact portion 243 provided on the leading end side in the loading direction of the slider portion 240 (see FIG. 18). Then, as the slide portion moves slightly in the discharge direction, the latch plate 250 also moves slightly in the discharge direction. At this time, the engagement between the claw portions 251 and 251 of the latch plate 250 and the recesses 211a and 211a of the ink cartridge 211 is loosened, and a clearance, so-called clearance, is generated between the claw portions 251 and 251 and the recesses 211a and 211a. .

Accordingly, the claw portions 251 and 251 are not subjected to any force from the ink cartridge 211. Then, when the latch plate spring 256 acts on the latch plate 250, the leading end side in the loading direction of the latch plate slit 255 abutted at the time of loading is separated from the slider protrusion 242 and the latch plate 250 is The slider portion 240 is engaged by the engaging means.
Since the biasing force of the discharge lever 385 is smaller than the frictional force between the ink cartridge 211 and the ink supply needle 411, the ink cartridge 211 does not move.

FIG. 19 is a side cross-sectional view of the main part showing the attachment / detachment device in the middle of discharging the ink cartridge.
As shown in FIG. 19, when the lever arm 363 is gradually rotated further to the “reset position” side from the state of FIGS. 17 and 18, the slider portion 240 further gradually moves to the left side of the drawing, which is the discharging direction. At this time, the contact portion 243 provided on the slider portion 240 is in contact with and pressed against the tip portion of the ink cartridge 211. Therefore, against the frictional force between the ink cartridge 211 and the ink supply needle 411, the contact portion 243 gradually moves the ink cartridge 211 to the left side in the drawing, which is the discharge direction. At this time, the contact portion 243 is provided at a position facing the two claw portions 251 and 251. Similarly to the fact that the claw portion is pushed in while stabilizing the posture of the ink cartridge 211 during loading, the two contact portions 243 and 243 are in the discharging direction while stabilizing the posture of the ink cartridge 211 during discharging. The ink cartridge 211 can be moved.

  Further, as the slider portion 240 moves in the discharging direction, the pair of inclined portions 253 and 253 of the latch plate 250 gradually rides on the tip contact portions 260c and 260c of the cancel arms 260a and 260b. At this time, the tip contact portions 260c and 260c urge the latch plate 250 to be engaged by the first engaging means via the inclined portions 253 and 253, and latch via the inclined portions 253 and 253. The plate 250 is pushed upward. Then, the latch plate 250 starts to swing upward with the position where the slider engaging portion 245 and the latch plate engaging portion 254 as the first engaging means are engaged with each other.

  At this time, since the claw portions 251 and 251 extend downward, the diameter of the orbit at the lower end of the claw portions 251 and 251 is larger than the other portions, but the claw portions 251 and 251 and the recesses 211a and 211a described above The claw portions 251 and 251 are provided so as to be able to rise without receiving frictional resistance. Here, the gap is very small, but the first engagement means is in surface contact and the positions and trajectories of the claw portions 251 and 251 can be determined rigidly, so that the latch plate 250 swings upward. When moving, there is no possibility of friction between the claw portions 251 and 251 and the recesses 211a and 211a.

FIG. 20 is a side perspective view showing the attachment / detachment device in the middle of discharging the ink cartridge, and FIG. 21 is a side sectional view of the main part of FIG.
As shown in FIGS. 20 and 21, when the lever arm 363 is gradually rotated further to the “reset position” side from the state shown in FIG. 19, the slider portion 240 is gradually moved further in the discharging direction. At this time, the inclined portions 253 and 253 of the latch plate 250 completely ride on the tip contact portions 260c and 260c of the cancel arms 260a and 260b. Therefore, the latch plate 250 reaches the highest point of swinging upward, and the claw portions 251 and 251 are completely disconnected from the recesses 211a and 211a, and the engagement is released.
Here, since the upward swing of the latch plate 250 requires a gap between the claw portions 251 and 251 and the recesses 211a and 211a, the contact portions 243 and 243 move the ink cartridge 211 in the discharge direction. It is configured to be performed during

On the other hand, the contact portions 243 and 243 move the ink cartridge 211 in the discharge direction until the ink supply needle 411 is almost completely removed from the ink cartridge 211 and the relatively large frictional resistance between the ink cartridge 211 and the ink supply needle 411 disappears. Let
After the frictional resistance between the ink cartridge 211 and the ink supply needle 411 disappears, the push lever 401 provided with the slider portion 240 acts to move the ink cartridge 211 against the slider portion 240 which is the cartridge holding means 210. Forcibly move in the discharge direction. The push lever 401 is provided to move the ink cartridge 211 against the relatively small frictional resistance between the ink cartridge 211 and the connector portion 412 described above.

  Here, the push-out lever 401 comes into contact with an extruding portion 401b (see FIG. 22) that pushes out and pushes the ink cartridge 211 at one end, and a protrusion (not shown) provided on the base 387 of the detachable device 201 at the other end. A contact portion 401a (see FIG. 22) to be engaged is provided, and the slider portion 240 is provided so as to rotate about a fulcrum. The rotated push lever 401 returns to its original position (position shown in FIG. 17) by the push lever spring 402 when the engagement between the protrusion (not shown) and the contact portion 401a is released. It is configured. As for the specific operation, when the slider part 240 moves in the discharging direction, the contact part 401a of the push lever 401 that moves together with the slider part 240 engages with a protrusion (not shown) of the base body 387, thereby making contact. The part 401a becomes the power point of the lever principle, and the push-out lever 401 rotates. Then, the push-out portion 401b becomes an action point of the lever principle, and the ink cartridge 211 is forcibly moved with respect to the slider portion 240 in the third predetermined stroke S3 (see FIGS. 22 and 23) discharge direction.

At this time, the push lever 401 moves the ink cartridge 211 in the ejecting direction with respect to the slider portion 240 by the third predetermined stroke S3, so that the lever arm 363 is rotated in the reverse direction to the “set position” side, so-called erroneous operation. Even when the latch plate 250 swings downward due to the (abnormal operation), there is no possibility that the claw portions 251 and 251 and the concave portions 211a and 211a are engaged again.
Here, the “third predetermined stroke S3” is a moving distance of the ink cartridge 211 with respect to the slider portion 240, from a position where the claw portions 251 and 251 and the concave portions 211a and 211a are engaged to a position where they are not engaged. The distance traveled.

In FIG. 21, the ink supply needle 411 appears to pierce the ink cartridge 211, but is completely removed from the packing (not shown) in the opening through which the ink supply needle 411 on the ink cartridge side is inserted. The friction resistance between the ink cartridge 211 and the ink supply needle 411 is already absent.
In this embodiment, the push lever 401 is configured to act against a relatively small frictional resistance between the ink cartridge 211 and the connector portion 412, but the ink cartridge 211 and the ink supply needle 411 Of course, it may be configured to act against a relatively large frictional resistance.

FIG. 22 is a plan view showing the attachment / detachment device in the middle of discharging the ink cartridge, and FIG. 23 is a sectional side view of the main part of FIG.
As shown in FIGS. 22 and 23, when the lever arm 363 is gradually rotated further to the “reset position” side from the state shown in FIGS. 20 and 21, the slider part 240 further gradually moves in the discharging direction. Then, after the push lever 401 moves the ink cartridge 211 relative to the slider portion 240 against the relatively small frictional resistance between the ink cartridge 211 and the connector portion 412, the ink cartridge 211 and the attachment / detachment device 201 are moved. There is almost no frictional resistance. Accordingly, the urging force of the discharge lever 385 tries to push the ink cartridge 211 in the discharge direction.

  FIG. 24 is a side cross-sectional view of the main part showing the attachment / detachment device in the middle of discharging the ink cartridge. As shown in FIG. 24, when the lever arm 363 is gradually rotated further to the reset side from the state shown in FIGS. 22 and 23, the slider 240 further gradually moves in the discharging direction. At this time, the ink cartridge 211 is pushed out in the discharge direction by the urging force of the discharge lever 385. Thereafter, the inclined portions 253 and 253 of the latch plate 250 get over the tip contact portions 260c and 260c of the cancel arms 260a and 260b. Accordingly, the latch plate 250 swings downward after the ink cartridge 211 is moved in the discharge direction by the discharge lever 385.

The ink cartridge 211 that has moved in the discharging direction by the urging force of the discharging lever 385 jumps out of the insertion opening 271 by about half of its body, and comes into contact with the lever protrusion 363 c of the lever arm 363 and stops.
When the lever arm 363 is completely rotated to the “reset position” (see FIGS. 4 to 6, 8 and 9) and the lever protrusion 363 c is moved to the outside of the entry path A, the ink cartridge 211 is inserted. It can be taken out from the opening 271.

FIG. 25 is a plan view showing the shape of the cam portion according to the present invention.
As shown in FIG. 25, the cam portion 235 is provided so as to rotate about the cam shaft 235c, an eccentric cam portion 235a eccentric with respect to the cam shaft 235c, and a concentric cam portion concentric with the cam shaft 235c. 235b. As described above, when the lever arm 363 is rotated from the “reset position” to the “set position”, the cam portion 235 is rotated counterclockwise as shown in FIG. At this time, since the eccentric cam portion 235a presses the first surface 246a of the first slider opening 246, the slider portion 240 is guided by the guide slits 241a and 241b and the shafts 262a and 262b in the loading direction of the arrow. Moving.

  When the lever arm 363 is at a position immediately before the “set position”, the concentric cam portion 235b comes into contact with the first surface 246a. When the lever arm 363 is further rotated to the “set position”, the state shown in FIG. That is, when the lever arm 363 is at a position immediately before the “set position”, the slider 240 has already been moved by the second predetermined stroke S2 necessary for loading. Thereafter, even if the lever arm 363 is rotated from the position immediately before the “set position” to the “set position”, the concentric cam portion 235b is in contact with the first surface 246a, so that the slider portion 240 moves. There is no. That is, even if the lever arm 363 is further rotated, the moving distance of the slider portion 240 does not become a so-called overstroke.

  Accordingly, the slider 240 can be configured not to follow the position (phase) of the lever arm 363 within a certain range. That is, by providing “play” of about several degrees, the slider 240 can be moved in the second predetermined stroke S2 loading direction without completely turning the lever arm 363 to the “set position”. In this case, even if the slider portion 240 is completely rotated to the “set position”, the moving distance of the slider portion 240 remains the second predetermined stroke S2. Therefore, the moving distance of the slider portion 240 when the ink cartridge 211 is loaded can be easily managed.

  For example, when the ink cartridge 211 is loaded, even if the user stops the operation at a position immediately before the “set position” without accurately rotating the lever arm 363 to the “set position”, the slider 240 Can be reliably moved by the second predetermined stroke S2. That is, even if the position where the user stops the operation of the lever arm 363 is varied, the ink cartridge 211 can be loaded by reliably moving the slider portion 240 by the second predetermined stroke S2.

  Here, the “position immediately before the set position” is an intermediate position between the “reset position” and the “set position”, and is a position biased toward the “set position” side. It is desirable that the degree of deviation is such that the concentric cam portion 235b is already in contact with the first surface 246a at a position where the user tends to stop the lever arm 363 when the ink cartridge 211 is loaded.

  Further, in a state where the slider portion 240 is moved in the loading direction by the second predetermined stroke S2, the first surface 246a is always in contact with the concentric cam portion 235b. In this state, the urging force is applied to the ink cartridge 211 so that the discharge lever 385 and the valve lever move the ink cartridge 211 in the discharge direction as described above. Furthermore, there is a possibility that a force that causes the ink cartridge 211 to come out of the ink supply needle 411 is generated, and the ink cartridge 211 is moved in the discharge direction. Therefore, a force that always moves the slider portion 240 in the discharging direction is applied. In this embodiment, since the concentric cam portion 235b is always in contact with the first surface 246a in the state where the loading movement is completed, even if the first surface 246a presses the concentric cam portion 235b, There is no possibility of generating a force to rotate about the cam shaft 235c. Therefore, even when an external force is applied, the slider portion 240 does not move unless the lever arm 363 is rotated to the “reset position” side.

  In the present embodiment, when the lever arm 363 is rotated from the “set position” to the “reset position” side, the lever arm 363 is immediately before the “reset position” in the same manner as when the lever arm 363 is rotated to the “set position” side. The concentric cam portion 235b comes into contact with the second surface 246b at the position. In other words, the slider 240 can be moved in the discharging direction of the second predetermined stroke S2 without completely rotating the lever arm 363 to the “reset position”. Even if it rotates, the moving distance of the slider portion 240 in the discharging direction remains the second predetermined stroke S2.

  Further, when the lever arm 363 is in the “reset position”, the concentric cam portion 235b is in contact with the second surface 246b. Therefore, as described above, the ink cartridge 211 is inserted from the insertion opening 271 for the first predetermined stroke S1, and the ink cartridge 211 is further pushed in with the ink cartridge 211 held by the cartridge holding means 210. Even in this case, the slider portion 240 cannot be moved in the loading direction unless the lever arm 363 is rotated to the “set position” side. That is, even when the ink cartridge 211 is to be pushed beyond the first predetermined stroke S1, the position of the ink cartridge 211 is regulated by the contact portion 243 of the slider portion 240.

Of course, the shape and type of the cam portion of the present invention is not limited to the above embodiment, and may be a groove cam or the like.
In the present embodiment, two claw portions are provided, but one claw portion extending in the width direction may be provided, or, of course, three or more claw portions may be provided in the width direction.
Furthermore, in the present embodiment, the swing fulcrum of the latch plate is provided on the upstream side of the claw portion in the loading direction, but it may of course be on the downstream side.

Next, the lid member that opens and closes the insertion opening 271 will be described.
FIG. 26 is an enlarged perspective view of a main part showing an erroneous detection preventing means of the ink cartridge attaching / detaching device. FIGS. 27A and 27B are side sectional views showing the erroneous detection preventing means. Among these, (A) is a state in which the lid member is closed, while (B) is a state in which the lid member is open.

  As shown in FIGS. 26, 27A, and 27B, a lid member 454 that can open and close the insertion opening 271 is provided at the entrance of the insertion opening 271 of the ink cartridge 211. The lid member 454 rotates with the lid shaft 455 as a fulcrum. When the lid member 454 shown in FIG. 27A is closed, the lid lever 456 provided on the lid member 454 has a sensor opening provided in a slit shape. The sensor lever 452 of the open / close sensor 451 provided on the recording apparatus main body side is brought into contact with and pressed through the portion 453. The open / close sensor 451 is configured to detect that the lid member 454 is closed and send a signal to the control unit 457. Further, the ink cartridge attaching / detaching device 201 is provided with an erroneous detection preventing means 450, and the erroneous detection preventing means 450 includes a sensor opening 453 and a lid lever 456. The sensor opening 453 is provided above the vicinity of the lid shaft 455 as shown in FIGS.

  In the state where the lid member 454 shown in FIG. 27A is closed, if the ink cartridge 211 is normally loaded as described above, the ink remaining amount information terminal 212 on the ink cartridge side and the recording device side A connector portion 412 is provided to be connected. When the control unit 457 recognizes the closure of the lid and the connection between the ink remaining amount information terminal 212 and the connector unit 412, that is, judges with AND, the recording apparatus 100 is configured to be operable. Accordingly, the ink remaining amount information terminal 212 is not connected to the connector portion 412 before the ink cartridge 211 is inserted, and therefore the recording apparatus 100 does not operate even when the lid member 454 is closed.

On the other hand, when the lid member 454 shown in FIG. 27B is opened, the lid lever 456 is separated from the sensor lever 452 of the open / close sensor 451 as the lid member 454 rotates counterclockwise. At this time, a part of the lid lever 456 is formed in a fan shape with a lid shaft 455 provided in the attachment / detachment device 201 as a fulcrum. Specifically, the sensor opening 453 is closed at a portion connecting the arc from the fan-shaped fulcrum (455), and the sensor lever 452 is abutted and pressed at the end of the arc. Therefore, the lid lever 456 can always maintain the state where the sensor opening 453 is closed. As a result, there is no possibility that foreign matter enters the sensor opening 453 and comes into contact with the sensor lever 452. Further, even when the lid member 454 in which dust easily enters the inside of the recording apparatus is open, the lid lever 456 blocks the sensor opening 453, which is also a dust-proof measure. As a result, it is possible to prevent the open / close sensor 451 from erroneously detecting the lid closing of the lid member 454 when the lid member 454 is opened.
Here, the state in which the lid lever 456 “closes the sensor opening 453” means that there is a slight gap (clearance) that does not hinder the rotation of the lid member 454, but hardly transmits light from the outside to the inside. It means a state that is closed to some extent.

  In the present embodiment, the rotation range of the lid member 454 is about 90 degrees, but may be 90 degrees or more. Of course, the open / close sensor 451 may be a non-contact type sensor. In the present embodiment, the insertion opening 271 and the sensor opening 453 are provided independently, but they may be integrated.

An ink cartridge attaching / detaching device 201 according to the present embodiment is an ink cartridge attaching / detaching device 201 for inserting an ink cartridge 211 as a member to be attached into an insertion opening 271 provided in the attachment / detachment device main body. A lid member 454 that pivots so as to be opened and closed, an open / close sensor 451 as a detecting means for detecting the closure of the lid member 454 on the attachment / detachment apparatus main body side, and the lid member 454 in a state where the lid member 454 is not closed. And erroneous detection preventing means 450 for preventing erroneous detection of erroneously detecting the blockage of 454. The erroneous detection prevention means 450 is provided on the lid member side and is detected by the open / close sensor 451 when the lid member 454 is closed. A lid lever 456 as a member to be detected, and a lid lever 456 that is provided on the side of the detachable device main body and is inserted when the lid lever 456 rotates. And a sensor opening 453 of the member to be detected through the opening, the lid lever 456, at least when the lid member 454 is opened, characterized in that it is configured to block the sensor aperture 453.
Here, an example of the attachable / detachable member is the ink cartridge 211, but it is needless to say that the ink cartridge is not limited thereto.

  In this embodiment, the member to be attached / detached is the ink cartridge 211, and an electrical connection terminal portion provided on the ink cartridge side and a connector portion 412 that can contact the connection terminal portion on the attachment / detachment device main body side. The connecting terminal portion and the connector portion 412 are in electrical contact with each other, and when the opening / closing sensor 451 as the detecting means detects the closure of the lid member 454, the recording device 100 including the attachment / detachment device 201 is activated. It is comprised by these.

The lid shaft 455 may be provided inside the attachment / detachment device, that is, inside the sensor opening 453. In such a case, the lid lever 456 can block the sensor opening 453 from the inside. Therefore, the lid lever 456 can counter an external force applied to a foreign object that is about to enter the sensor opening 453.
Further, the present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say.
