<Overview of inkjet recording apparatus>
FIG. 1 is a perspective view showing an ink jet recording apparatus according to an embodiment of the present invention. As shown in FIG. 1, the ink jet recording apparatus 11 of this embodiment includes a paper feed unit 101, a transport unit 102, a recording mechanism unit 103, and a recovery mechanism unit 104. The paper supply unit 101 supplies a sheet (recording medium) into the apparatus main body. The transport unit 102 transports the recording medium supplied from the paper feed unit 101. The recording mechanism unit 103 operates based on image information and records an image on a recording medium. The recovery mechanism unit 104 maintains or recovers the ink ejection performance of the recording head in order to maintain the quality of the recorded image.

  The recording mechanism unit 103 includes a carriage 12 that can reciprocate in the main scanning direction, and a recording head 5 that is detachably mounted on the carriage 12. The carriage 12 is guided and supported so as to be capable of reciprocating along a guide rail installed in the apparatus main body. The reciprocating movement of the carriage 12 is performed by transmitting the driving force of the carriage motor via the carriage belt 124, and the position of the carriage 12 and the position of the carriage 12 are measured by an encoder sensor mounted on the carriage and an encoder scale stretched on the apparatus main body side. It is controlled by detecting the speed. An image or the like can be recorded on a recording medium by ink ejection from the recording head 5 performed in synchronization with the movement of the carriage 12.

  In addition to the recording head 5, a sub tank (not shown) that temporarily stores ink to be supplied to the recording head 5 is mounted on the carriage 12.

<Recovery mechanism 104>
FIG. 4 is a perspective view showing the recovery mechanism unit 104 according to the first embodiment of the present invention. The slider 7 is provided with an abutting portion 7 a that contacts the side surface of the carriage 12. Accordingly, the slider 7 can move within a predetermined range following the movement of the carriage 12. On the slider 7, wipers 8, 9 and caps 1A, 1B are provided. By moving the slider 7 as described above, the wipers 8 and 9 and the caps 1 </ b> A and 1 </ b> B can take their respective retracted positions away from the recording head 5. Further, from the retracted position, a wiper position where the discharge port surfaces 51 and 52 of the recording head 5 can be wiped off by the wipers 8 and 9 and a discharge port surface 51 and 52 of the recording head 5 by the caps 1A and 1B. Can be moved to a capping position capable of covering.

  On the side surface of the slider 7, there are provided four protrusions 7 b that protrude in a direction orthogonal (crossing) to the moving direction of the carriage 12. These protrusions 7b are in contact with a slider cam 13a provided in the apparatus main body. Further, the slider 7 is attached with one end of a slider spring 17 stretched between the apparatus main body side and the slider 7, and is urged so as to move to the retracted position. The slider 7 is moved along the cam surface of the slider cam 13a provided on the apparatus main body by sliding the four projecting portions 7b (retracted position, wiping position, capping position) along the carriage moving direction. The position is controlled to be a predetermined height with respect to the discharge port surface. A wiper 8 for wiping the discharge port surface of the recording head 5 that discharges color ink and a wiper 9 for wiping the discharge port surface of the recording head 5 that discharges black ink are attached to the slider 7. . Further, caps 1A and 1B for capping the discharge port surface are attached to the cap holders 2A and 2B, and these cap holders 2A and 2B are attached to the slider 7 by four claw portions. Cap springs are arranged between the cap holders 2A and 2B and the slider 7, and the cap holders 2A and 2B to which the caps 1A and 1B are attached are urged toward the discharge port surface. The wipers 8, 9 and the caps 1A, 1B are arranged in the order of the wiper 8, the cap 1A, the wiper 9, and the cap 1B from the recording area side.

  As shown in FIG. 4, the slider 7 includes a lock lever 16 as a locking member that operates to lock (lock) the slider 7 to the wiping position at the downstream side in the conveyance direction at the recording region side end. Is attached. The lock lever 16 is rotatably attached to a locking position for locking the slider 7 at the wiping position and a release position for releasing the locked state of the slider 7. Specifically, the lock lever 16 is supported so as to be able to rotate and move within a plane orthogonal to (intersects with) the moving direction of the carriage 12, and can rotate around the support shaft 16e. The lock lever 16 is subjected to a spring biasing force in the radial direction. As a result, the position of the lock lever 16 is a position rotated by the urging force unless an external force torque of a predetermined value or more is applied. The position is a position where the protrusion 16 f of the lock lever 16 is in contact with a part of the slider 7 as shown in FIG. 5.

  The lock lever 16 having the above configuration locks the slider 7 to the apparatus main body side when the slider 7 moves to the wiping position in order to wipe the discharge port surface of the recording head 5 by the movement of the carriage 12. The movement of the slider 7 is restricted.

  On the apparatus main body side, there is provided an engaging portion 13d that can be engaged with the distal end portion 16a of the lock lever 16 when the protruding portion 16f of the lock lever 16 and the slider 7 come into contact with each other as described above. (See FIG. 6). Wiping is performed in a state where the front end portion 16a of the lock lever 16 is engaged with the engaging portion 13d. On the other hand, the carriage 12 is provided with an unlocking protrusion (not shown) that can come into contact with the upper end 16 b of the lock lever 16. When the carriage 12 moves toward the recording area, the unlocking protrusion comes into contact with the upper end portion 16b of the lock lever 16, thereby rotating the lock lever 16 clockwise. As a result, the distal end portion 16a of the lock lever 16 is separated from the engaging portion 13d, and the locked state by the lock lever 16 is released.

  As shown in FIG. 7, a locking release portion 13 g for releasing the locked state (wiper lock) of the slider 7 fixed at the wiping position is provided on the apparatus main body side. As a result, when the lock lever 16 comes into contact with the locking release portion 13g, the lock lever 16 is rotated to the release position.

  As shown in FIGS. 6 and 7, the lock lever 16 is provided with a release lever (regulating member) 18 for releasing the locked state of the slider 7 fixed at the wiping position. The release lever 18 is provided so as to be able to rotate and move in a plane orthogonal to (crossing) the moving direction of the carriage. That is, the release lever 18 has a support shaft 18e, and is supported so as to be rotatable about the shaft. In addition, by applying a spring biasing force in the radial direction to the release lever 18, the position moved by the spring biasing force is maintained unless an external force torque of a predetermined value or more is applied.

  A restricting portion 13h is provided on the apparatus main body side, so that when the slider 7 moves to the wiping position, the tip end portion 18a of the release lever 18 cannot move the lock lever 16 to the locking position. The release lever 18 rotates from the lock avoidance position to the lockable position where the lock lever 16 can be moved to the lock position, or the release lever from the lockable position to the lock avoidance position. It can regulate that 18 rotates. When the slider 7 moves to a position beyond the wiping position, the tip end portion 18a of the release lever 18 is released from the restriction by the restriction portion 13h. Thereby, the front-end | tip part 18a of the cancellation | release lever 18 rotates to the latching avoidance position from the latching possible position with a spring biasing force. When the slider 7 is moved toward the recording area in this state, the movement of the distal end portion 18a of the release lever 18 to the lockable position at the wiping position is restricted by the restriction portion 13h. The wiper can be returned to the retracted position without performing the wiping operation.

  The release lever 18 is made of a material different from that of the lock lever 16 and the restricting portion 13h. This avoids an increase in sliding load due to the same material.

<Operation when performing wiping operation>
Next, the operation when the wiping operation is performed will be described in detail. FIG. 8 is a perspective view showing a state where the slider 7 is in the retracted position. When the carriage 12 does not move to the capping region of the recovery mechanism 104 during a recording operation or the like, the slider 7 is in the retracted position, and the lock lever 16 is in the release position that is rotated clockwise from the locking position. ing. FIG. 9 is a perspective view showing a state in which the slider 7 has moved to the wiper trigger position. FIG. 10 is a front view showing a state in which the slider 7 has moved to the wiper trigger position. FIG. 11A is a flowchart showing an operation when a wiping operation is performed. In particular, the movement control of the carriage shown in this flowchart is performed by the MPU 201 controlling the drive of the carriage motor 204 via the carriage motor driver 208. The carriage movement control shown in FIG.

  As the carriage 12 moves from the recording area toward the recovery mechanism unit 104, the abutting portion 7 a of the slider 7 contacts the side surface of the carriage 12. As a result, the slider 7 follows the carriage 12 and moves together with the carriage 12 in the direction of arrow A shown in FIG. As the slider 7 moves in the direction of the arrow A, the slider 7 rises along the cam surface of the slider cam 13a.

  When the slider 7 makes this movement (step 401; FIG. 8), the lock lever 16 is rotated counterclockwise as shown in FIG. 8 by the spring biasing force. And the front-end | tip part 16a of the lock lever 16 latches to the engaging part 13d of the apparatus main body side, and the attitude | position is hold | maintained. Subsequently, the carriage 12 reverses the moving direction before the front end portion 18a of the release lever 18 is released from the restriction by the restriction portion 13h (step 402; FIG. 9). Here, the inversion position is referred to as “wiper trigger position”. When the carriage 12 reverses the moving direction, the slider 7 moves along the slider cam 13a by the spring biasing force of the slider spring 17, and starts to descend. When the slider 7 is lowered by a predetermined amount, the distal end portion 16a of the lock lever 16 comes into contact with the engaging portion 13d on the apparatus main body side. As a result, the slider 7 stops at the wiping position.

  When the carriage 12 moves further from the wiping position toward the recording area, the carriage 12 moves away from the slider 7. When the carriage 12 further moves toward the recording area, the wipers 8 and 9 provided on the slider 7 are brought into sliding contact with the discharge port surface of the recording head 5 mounted on the carriage 12 to perform a wiping operation (step) 403).

  When the carriage 12 further moves toward the recording area and the wiping operation of the discharge port surface by the wipers 8 and 9 is completed, the protrusion provided on the carriage 12 comes into contact with the upper end portion 16b of the lock lever 16. The lock lever 16 rotates about the support shaft 16e in the clockwise direction shown in FIG. As a result, the distal end portion 16a of the lock lever 16 is separated from the engaging portion 13d, and the locked state of the lock lever 16 is released. The released slider 7 is moved by the spring biasing force of the slider spring 17 to the lowest position near the recording area along the slider cam 13a and returned to the retracted position shown in FIG.

<Operation when wiping operation is not executed>
Next, the operation when no wiping operation is performed will be described. FIG. 11B is a flowchart showing the operation when the wiping operation is performed. FIG. 12 is a perspective view showing a state in which the slider 7 moves toward the capping position.

  As shown in FIG. 9, when the carriage 12 is moved to the wiper trigger position (step 501; FIG. 9), the lock lever 16 is rotated clockwise by coming into contact with the locking release portion 13g. As a result, the lock lever 16 rotates and moves to a release position in which the distal end portion 16a is separated from the engaging portion 13d. At this time, the distal end portion 18a of the release lever 18 is restricted from moving to the locking avoidance position by the restricting portion 13h (step 501; FIG. 9). When the carriage 12 moves to a position deeper than the wiper trigger position with respect to the recording area, the distal end portion 18a of the release lever 18 is released from the restriction by the restriction portion 13h (step 502; FIG. 12). As a result, the distal end portion 18a of the release lever 18 is rotated and moved clockwise as shown in FIG. 12 by the spring biasing force, and moves from the lockable position to the lock avoidance position (step 502; FIG. 12). When the slider 7 that moves together with the carriage 12 reaches the uppermost value (capping position), the caps 1A and 1B on the slider 7 are pressed against the ejection port surfaces of the recording heads 5A and 5B, and the capping covers the ejection port. Is done.

  The carriage 12 reverses the moving direction from the capping position and starts moving toward the recording area (step 503). When the carriage 12 reverses the moving direction, the slider 7 moves along the slider cam 13a by the spring biasing force of the slider spring 17, and starts to descend. At this time, the release lever 18 is kept in the latch avoidance position.

  As the carriage 12 further moves toward the recording area, when the slider 7 moves to the wiping position, the tip end portion 18a of the release lever 18 can be rotated to the lockable position by the restricting portion 13h. It is regulated (step 504; FIG. 13). Thereby, when the slider 7 moves to the wiping position, it passes through the wiping position without being locked and returns to the retracted position. Finally, the release lever 18 returns to the retracted position shown in FIG. 8 through a route different from that when wiping is performed.

  As described above, presence / absence of the wiping operation can be selectively switched, and unnecessary wiping operation can be avoided.

(Second Embodiment)
As shown in FIGS. 14 (a) and 15 (a), in the first embodiment of the present invention described above, the distal end portion of the release lever 18 that is rotatably attached to the lock lever 16 at the wiper trigger position. The movement of the lock 18a from the lockable position to the lock avoidance position is restricted by the restricting portion 13h, and thereby rotates counterclockwise with respect to the lock lever 16. In the capping position, the distal end portion 18a of the release lever 18 is released from the restriction by the restriction portion 13h, rotates clockwise with respect to the lock lever 16, and moves from the lockable position to the lock avoidance position.

  On the other hand, in the second embodiment of the present invention, as shown in FIGS. 14 (b) and 15 (b), the lock lever 16 has an elastic deformation portion 16f, and the elastic deformation portion at the wiper trigger position. 16f is restricted from moving from the lockable position to the lock avoidance position by the restricting portion 13h and elastically deformed, and released from the restriction at the capping position, the deformation is eliminated, and the lock is released from the lockable position. It is set as the structure which moves to an avoidance position. In this case, since the release lever 18 and the urging member for urging the release lever 18 are unnecessary, the number of parts can be reduced and the cost can be reduced accordingly.

(Other embodiments)
In the above-described embodiment, the ink tank that stores the ink to be supplied to the recording head is provided at a location different from the carriage (front surface of the apparatus main body), but the application of the present invention is not limited to this configuration. The present invention can also be applied to an embodiment in which an ink tank (ink cartridge) is detachably mounted on the carriage.
