When the operator grips the box handle 44 and pulls it forward, the waste toner box 31 is pulled out to the disengaged position where it is removed from the image forming apparatus main body U2.
At this time, in FIG. 5, the discharge port 1 a of the discharge path 1 is closed by the shutter 2 that moves to the closed position by the tension spring 4, and the inlet 34 a of the container body 32 moves to the closed position by the coil spring 38. The shutter 36 closes. Further, when the coupling 6 is separated from the box coupling 39, the coupling 6 moves from the connection position to the front separation position.

Here, in a configuration in which the latch 19 does not move from the lock position to the release position in conjunction with the movement of the box handle 44 from the standby position to the pull-out position, an operation for releasing the latch 19 and the holding of the box handle 44 Two operations of pulling out the waste toner box 31 are required.
On the other hand, in the first embodiment, when the waste toner box 31 is pulled out, the latch 19 is automatically released simply by moving the box handle 44 from the standby position toward the pull-out position. As compared with the configuration in which the latch 19 is not interlocked, the operation procedure is reduced.
In particular, in the first embodiment, the release protrusion 48 is formed integrally with the box handle 44, and a simple configuration with a reduced number of parts compared to the case where the box handle 44 and the release protrusion 48 are configured separately. Thus, the movement of the latch 19 is interlocked with the movement of the box handle 44.

In addition, when the waste toner box 31 moves forward from the mounting position in a state where the latch is released, the latch 19 contacts the release protrusion 48 and the container protrusion 42 in order to maintain the release position. When the container projecting portion 42 is moved forward from the position of the latch 19, the container projecting portion 42 is moved from the locking position to the projecting position when released by the urging force of the latching coil spring 21. Therefore, the spring receiving portion 19 a of the latch 19 closes the boss passage port 18.
At this time, if the front cover U2b is moved from the open position toward the normal position without mounting the waste toner box 31, the cover boss 26 comes into contact with the spring receiving portion 19a that closes the boss passage opening 18. The movement of the front cover U2b to the normal position is restricted and the front cover U2b cannot be closed. Therefore, forgetting to attach the waste toner box 31 is prevented.

When the waste toner box 31 is attached to the box attaching / detaching portion U2a, the waste toner box 31 is inserted into the box insertion port 11 from the rear end side and moved backward. At this time, the container projecting portion 42 of the container body 32 contacts the box contact member 13 and receives a forward biasing force by the push coil spring 14 before moving to the mounting position. The waste toner box 31 is moved rearward as it is against the urging force of the extrusion coil spring 14 and moved to the mounting position.
At this time, the latch guiding surface 42c of the container projecting portion 42 contacts the guided surface 19d1 of the latch 19 held at the projecting position at the time of separation. As the waste toner box 31 moves to the mounting position, the latch 19 is pushed by the latch guide surface 42c and moves from the protruding position at the time of separation shown in FIG. 10D to the release position shown in FIG. 10C. When the waste toner box 31 moves to the mounting position, the latch 19 protrudes into the box attaching / detaching portion U2a by the urging force of the latching coil spring 21, and moves to the locking position accommodated in the latch accommodating portion 42b. Thereby, the mounting of the box attaching / detaching portion U2a of the waste toner box 31 is completed.

In FIG. 5, the shutter 2 that closes the discharge port 1a is pushed by the waste toner box 31 and moves to the closing member opening position, and the shutter 36 that closes the inflow port 34a is pushed by the discharge port 1a. As a result, the discharge port 1a and the inflow port 34a are opened and connected. Further, the coupling 6 held in the separated position is engaged with the box coupling 39 and pushed rearward, and moves to the coupling position.
When the front cover U2b is closed after the installation of the waste toner box 31 is completed, the cover boss 26 passes through the boss passage port 18. Then, in a state where the cover boss 26 is housed in the boss housing recess 19f of the latch 19, the front cover U2b is held at the normal position, and an image forming operation is performed.

Here, when the latch 19 is pushed to the release position and the latching coil spring 21 is compressed while the waste toner box 31 is pushed toward the mounting position, the elastic restoring force of the latching coil spring 21 increases. Then, the waste toner box 31 is pushed by the increased restoring force, which becomes a resistance of the pushing operation. Further, the coil spring 7 of the coupling 6 and the springs 4 and 38 of the shutter 2 and the box shutter 34 also serve as resistances for the operation of pushing the waste toner box 31.
Therefore, while the operator is pushing the waste toner box 31 toward the mounting position, it may be misunderstood that the movement to the mounting position is completed even though the load is felt and it is in the half-mounted state.

Here, in the conventional configuration in which the box extruding member 13 + 14 is not provided, even if a force that pushes back the waste toner box 31 by the coil spring 7 of the coupling 6 or the springs 4 and 38 of the shutter 2 and the box shutter 34 is acting. The waste toner box 31 is not pushed back by being pressed by the latch 19 due to the elastic restoring force of the latching coil spring 21, and the semi-mounted state may not be recognized.
In such a case, when the image forming operation is performed, the waste toner conveyed from the image recording apparatus U3 is discharged from the discharge port 1a without completing the connection between the discharge port 1a and the inflow port 34a, and the box is attached / detached. There is a risk that it will flow into the portion U2a and stain the image forming apparatus main body U2.

On the other hand, in the first embodiment, the waste toner box 31 is urged forward by the box extruding member 13 + 14. In the half-mounted state, the waste toner box 31 is pushed forward, and the latch 19 Moves to the protruding position when leaving. Therefore, in the first embodiment, compared with the configuration in which the box extruding member 13 + 14 is not provided, the waste toner box 31 pops forward by being pushed by the box extruding member 13 + 14, and the waste toner box 31 is half-mounted to the operator. Is easily recognized.
Here, in the first embodiment, the box contact member 13 is in contact with the container protruding portion 42 with which the latch 19 is in contact, and urges the waste toner box 31 to the front side. If the box contact member 13 is urged by contacting a position away from the container projecting portion 42, for example, if the box contact member 13 is urged by contacting the rear end of the waste toner box 31, the shape error of the waste toner box 31 may occur. Box contact member 13 absorbs the force pushing the waste toner box 31 by the box contact member 13 due to accumulation, elastic deformation, rattling, etc., or the relationship between the direction in which the box contact member 13 pushes and the direction of the force of the latch 19 13, the waste toner box 31 is not pushed out but is pressed by the latch 19, and a semi-mounted state may occur.

On the other hand, in the first embodiment, the box contact member 13 pushes the waste toner box 31 forward in the vicinity of the latch 19, and is less affected by the accumulation of shape errors and the like, so that the half-mounted state is reduced. ing.
The box extruding member 13 + 14 of the first embodiment moves along the front-rear direction, which is the moving direction of the waste toner box 31, and biases the waste toner box 31, and does not move along the front-rear direction. In comparison, the waste toner box 31 is pushed forward by the pushing coil spring 14 having a small elastic force.

  FIG. 13 is an explanatory view when the front cover moves from the open position toward the normal position when the waste toner box is held at the first half insertion position, and FIG. 13A is a view where the front cover is held at the open position. FIG. 13B is a continuation of FIG. 13A, an illustration of the front cover moving from the open position and the first rib contacting the rib receiving recess, and FIG. 13C is a continuation of FIG. 13B. FIG. 13D is an explanatory diagram continued from FIG. 13C and is an explanatory diagram showing a state in which the front cover is restricted by the box handle.

  In FIG. 13, with the waste toner box 31 in a semi-attached state, the operator releases his / her hand, and the waste toner box 31 pushed by the box push-out member 13 + 14 moves forward, so that the attachment position and the separation position are separated. There is a case in which a first half insertion position as an example of a first restriction position set in advance, which is a position between them, may move. At this time, if the operator removes his / her hand from the box handle 44, the box handle 44 is held at the standby position by its own weight. Then, when the operator moves the front cover U2b from the open position to the normal position without noticing half-mounting, the first rib 23 comes into contact with the inside of the rib housing recess 49a as shown in FIG. 13B.

  Then, as shown in FIGS. 13B to 13C, the box handle 44 receives an upward force and a backward force as the front cover U2b rotates to the normal position, and the handle shaft 44a is centered. While rotating, the waste toner box 31 is pushed backward. As shown in FIG. 13D, when the waste toner box 31 is moved to the mounting position, even if the box handle 44 receives a backward force, the waste toner box 31 does not move backward, and the box handle 44 is attached to the front cover U2b. Restricts rotational movement to the normal position.

Here, in the conventional configuration as described in Patent Document 1, the holding member that is movable or disabled in conjunction with the attachment / detachment of the toner storage portion contacts the abutting member of the opening cover, and the opening cover The opening and closing of is regulated. In other words, the attachment / detachment of the toner storage unit and the opening / closing of the opening cover are regulated via a separate member called a holding member.
On the other hand, in the first embodiment, when half-mounted, the rotation of the front cover U2b can be performed with a simple configuration in which the waste toner box 31 and the front cover U2b are in contact without using a member such as a holding member. The movement is restricted, and the incomplete mounting, that is, the half mounting state is determined.

Further, in a configuration in which the movement of the front cover U2b to the normal position is not restricted by contacting the waste toner box 31, the waste toner box 31 held at the first half insertion position has the front cover U2b in the normal position. If it moves toward, it will contact the front cover U2b and will move back.
If the waste toner box 31 is moved to the mounting position along with the movement of the front cover U2b, it is necessary to have strength against the urging force of the coil spring 7 of the coupling 6 and the box pushing member 13 + 14. The cost of U2b increases.
Further, in the front cover U2b having a low strength, the waste toner box 31 receives a front force due to the urging force of the coil spring 7 of the coupling 6 and the front cover U2b is deformed, and the front surface of the front panel 11, the front cover U2b, May be held in a semi-mounted state.

  On the other hand, in the first embodiment, when the waste toner box 31 is held at the first half insertion position, the front cover U2b is in contact with the waste toner box 31 so that the rotation is restricted and the front cover U2b is closed. Absent. Therefore, in the first embodiment, the worker can recognize the half-mounted state with a simple configuration of contact of members.

In the first embodiment, the hinge shaft 22a of the front cover U2b is configured to have stronger strength than the hinge shaft 44a of the box handle 44. Accordingly, if the operator attempts to close the front cover U2b with a strong force in a state where the rotational movement of the front cover U2b is restricted by the box handle 44, compared to the hinge shaft 22a on the image forming apparatus main body U2 side, The handle shaft 44a on the side of the waste toner box 31 that is a detachable body is easily damaged.
Therefore, in the first embodiment, the handle shaft 44a of the waste toner box 31 is easily damaged as compared with the configuration in which the hinge shaft 22a is easily damaged, and the replaceable waste toner box 31 side, not the image forming apparatus body U2, is damaged. It is easy to repair and replace even if it is damaged.

FIG. 14 is an explanatory diagram when the front cover moves from the open position toward the normal position when the waste toner box is held in the second half insertion position, and FIG. 14A is a diagram in which the front cover is held in the open position. FIG. 14B is an explanatory diagram continued from FIG. 14A, an explanatory diagram when the front cover moves from the open position and the second rib contacts the rib receiving recess, and FIG. 14C is a continuation of FIG. 14B. FIG. 14D is a continuation of FIG. 14C and is an explanatory view showing a state in which the front cover is restricted by the box handle.
In FIG. 14, when the operator releases his hand while the waste toner box 31 is half-mounted, the waste toner box 31 pushed by the box pushing member 13 + 14 moves forward and is collected in the waste toner box 31. Depending on the amount of waste toner and the momentum of movement, the toner moves to a second half insertion position as an example of a preset second restriction position that is a position between the mounting position and the first half insertion position. Sometimes.

  At this time, as in the case where the waste toner box 31 is moved to the first half insertion position, when the operator moves the front cover U2b from the open position to the normal position without noticing half-loading, as shown in FIG. 14B. In addition, the second rib 24 contacts the inside of the rib housing recess 49a. Then, as shown in FIGS. 14C to 14D, the box handle 44 rotates the front cover U2b to the normal position while in contact with the second rib 24, as in the case of contacting the first rib 23. regulate.

Therefore, even when the waste toner box 31 is moved to the second half insertion position, the operator recognizes the half-mounted state similarly to the case where the waste toner box 31 is moved to the first half insertion position.
In the first exemplary embodiment, when the waste toner box 31 is held on the detachment position side of the first half insertion position, the waste toner box 31 is hinged more than the first rib 23 when the front cover U2b is closed. 22 is in contact with the inner surface of the front cover U2b, which is remote from the front cover U2. Therefore, the component of the force for pushing the waste toner box 31 is small, and the rotational movement of the front cover U2b is restricted with little movement of the waste toner box 31.

  FIG. 15 is an explanatory diagram when the front cover moves from the open position toward the normal position when the waste toner box is held between the first half insertion position and the second half insertion position. Fig. 15B is an explanatory diagram when the front cover is held in the open position, and Fig. 15B is an explanatory diagram continued from Fig. 15A. The front cover moves from the open position and the guide edge of the first rib contacts the box handle. 15C is a continuation explanatory view of FIG. 15B, an explanatory view when the second rib comes into contact with the rib receiving recess, FIG. 15D is a continuation explanatory view of FIG. 15C, and FIG. 15E is a continuation view of FIG. It is a continuation explanatory drawing, and is an explanatory view of the state where the front cover was regulated by the box handle.

In FIG. 15, when the operator releases his hand while the waste toner box 31 is half-mounted, the waste toner box 31 pushed by the box pushing member 13 + 14 or the like moves forward and is collected in the waste toner box 31. Depending on the amount of waste toner and the momentum of movement, the toner may move to a position between the first half insertion position and the second half insertion position.
At this time, when the front cover U2b is moved from the open position to the normal position without noticing half-mounting, the front end side of the rib accommodating recess 49a of the box handle 44 is moved to the first rib as shown in FIG. 15B. 23 is in contact with the guide edge 23b.

  If the front cover U2b is moved toward the normal position as it is, the box handle 44 is pushed backward by the guide edge 23b while being held at the standby position, and the waste toner box 31 is moved to the second half insertion position. To do. Then, at the second half insertion position, the second rib 24 comes into contact with the inside of the rib accommodating recess 49 a of the box handle 44. 15C to 15E, the front cover U2b is restricted from rotating to the normal position in a state where the box handle 44 is in contact with the second rib 24.

Here, it is assumed that the first rib 23 and the second rib 24 are formed as one rib so as to contact the waste toner box 31 moved between the first half insertion position and the second half insertion position. In this case, it may be difficult to be caught inside the rib housing recess 49a, and the rotational movement of the front cover U2b may not be restricted. If the width in the front-rear direction of the rib receiving recess 49a is increased accordingly, the box handle 44 is enlarged.
Further, if another rib is provided between the first rib 23 and the second rib 24, the waste toner box 31 moved between the first half insertion position and the second half insertion position is brought into contact with the first rib 23 and the second rib 24. In this case, the length of each rib in the front-rear direction is shortened, the strength of the rib is reduced, and the rib is easily damaged when contacting with the box handle 44.

  On the other hand, in the first embodiment, the guide edge 23 is provided on the first rib 23, and the waste toner box 31 moved between the first half insertion position and the second half insertion position is replaced with the second half insertion. Moved to position. Therefore, even when the waste toner box 31 moves between the first half insertion position and the second half insertion position in a state where the strength of the rib is secured without the box handle 44 being enlarged, the contact of the members With this simple configuration, the rotational movement of the front cover U2b is restricted.
