The auger 2 is configured to be rotatable to transport a developer as an example of powder. A drop path 3 as an example of a conveyance path is connected to the downstream end (rear end) of the discharge path 1.

  At the lower end of the falling path 3, a main body shutter 4 as an example of an opening and closing member is supported. The main body shutter 4 is supported movably in the front-rear direction with respect to the outlet 3 a at the lower end of the falling path 3. Therefore, the body shutter 4 is configured to be able to open and close the outlet 3a. An elastic seal 4a as an example of a sealing member is supported on the body shutter 4 of the first embodiment in order to seal the outlet 3a in a state where the outlet 3a is closed. The elastic seal 4a is made of rubber as an example, but may be made of sponge or the like. Further, the main body shutter 4 of the first embodiment is always urged toward a position where the outlet 3 a is closed by a spring 4 b as an example of an urging member.

At the lower end of the falling path 3, a waste toner box 6 as an example of a storage unit is supported. The waste toner box 6 is accommodated in the main body of the copying machine U in a detachable manner with respect to the drop path 3.
At the upper end of the waste toner box 6, an inlet 6a connected to the outlet 3a is formed.
In the waste toner box 6 according to the first embodiment, a vibration receiving portion 6 b is formed on the bottom outer surface. The to-be-vibrated part 6b is comprised by the uneven | corrugated shape where hemispherical protrusion was located in a line with the front-back direction.
At the upper end of the waste toner box 6, a box shutter 7 as an example of an opening and closing member is supported. The box shutter 7 is supported so as to be able to open and close the inlet 6 a. The box shutter 7 is configured in the same manner as the main body shutter 4 and has an elastic seal 7 a and a spring 7 b.

Behind the waste toner box 6, an open / close cover 11 as an example of an open / close member is disposed. The open / close cover 11 is rotatably supported centering on a rotation shaft 11 a at the lower end. Therefore, the opening and closing cover 11 is configured to be able to open and close the space for accommodating the waste toner box 6 provided at the rear of the copying machine U. Therefore, when the operator opens and closes the opening and closing cover 11, the internal waste toner box 6 is configured to be removable and replaceable.
A gear 12 as an example of an interlocking member is supported on the rotation shaft 11 a of the opening / closing cover 11. Therefore, the gear 12 is also configured to be able to rotate and move as the opening and closing cover 11 rotates. In the first embodiment, the gear 12 is supported by the rotation shaft 11a. However, a gear train having a plurality of gears can be changed to a gear train.

A vibrating device 13 is disposed below the gear 12. The vibration device 13 according to the first embodiment includes a rack 13a as an example of a moving body. The rack 13a is formed in a plate shape extending in the front-rear direction. The rack 13a is movably supported by the main body of the copying machine U in the front-rear direction. Further, the rack 13a has a front portion extending downward of the waste toner box 6, and extends to a position facing the vibration receiving portion 6b.
At the rear of the rack 13a, a gear portion 13b that meshes with the gear 12 is formed. Therefore, as the gear 12 rotates in the forward and reverse directions, the rack 13a moves in the front-rear direction.
A vibrating portion 13c is formed at the front of the rack 13a. The vibrating portion 13c is disposed to be opposed to and in contact with the portion to be vibrated 6b. The vibrating portion 13c of the first embodiment is configured to have a concavo-convex shape in which hemispherical projections that project toward the portion to be vibrated 6b are arranged in the front-rear direction. Therefore, when the rack 13a moves in the front-rear direction, the vibrating portion 13c sequentially contacts the vibrated portion 6b.

(Operation of Example 1)
In the copying machine U according to the first embodiment having the above-described configuration, the developer flows into the waste toner box 6 and is accumulated in accordance with the image forming operation. When the waste toner box 6 becomes full and is replaced, the open / close cover 11 is first opened. Therefore, the rack 13 a moves via the gear 12 in accordance with the opening operation of the open / close cover 11. Therefore, the vibrating portion 13 c of the rack 13 a sequentially contacts the vibrated portion 6 b of the waste toner box 6. Therefore, the state in which the apexes of the projections are in contact with each other and the state in which the projections of the vibrating portion 13c enter between the projections of the portion 6b to be vibrated are repeated, and the waste toner box 6 is vibrated. Therefore, vibration is applied to the outlet 3 a and the vicinity of the inlet 6 a, which are connection portions between the drop path 3 and the waste toner box 6. Thus, the vibration is applied to the connection portion in conjunction with the opening of the opening and closing member. The width of the vibration (in the present embodiment, the width of the vertical movement of the portion 6b to be vibrated) is set in such a range that the inlet 6a and the outlet 3a do not deviate.

As shown in FIG. 4, when vibration is applied to the connection portion of the waste toner box 6, the developer 21 attached to the edge of the outlet 3 a or the inlet 6 a is dropped by vibration during drop transportation, and the waste toner box 6 is dropped. It is easy to fall inside.
When the opening and closing cover 11 is opened, the waste toner box 6 can be removed, and can be taken out from the rear surface of the copying machine U opened by the opening and closing cover 11 and replaced. When the waste toner box 6 is removed from the drop path 3, the shutters 4 and 7 close the outlet 3 a and the inlet 6 a by the elastic force of the springs 4 b and 7 b.
Therefore, in the copying machine U according to the first embodiment, when the waste toner box 6 is removed, the connection portion is vibrated before the inflow port 6 a and the flow outlet 3 a as the connection portion are detached. Therefore, when the waste toner box 6 is removed, the leakage of the developer 21 attached to the inlet 6 a and the outlet 3 a is reduced.

  In the first embodiment, the waste toner box 6 is vibrated in conjunction with the opening of the opening / closing cover 11, and the vibration is applied even if the waste toner box 6 is not actually detached. The opening and closing cover 11 of the first embodiment is a cover dedicated to replacing the waste toner box 6, and the situation in which the opening and closing cover 11 is opened is a situation where the waste toner box 6 is likely to be replaced. Accordingly, the waste toner box 6 is vibrated in a situation where the waste toner box 6 is likely to be removed from now.

  Although the open / close cover 11 exemplifies a configuration dedicated to replacement of the waste toner box 6, the present invention is not limited to this, and other replacement members, such as toner cartridges Ky to Kk, photoreceptor units UY to UK, belt module BM, etc. It is also possible to use a dual-purpose cover that is also opened and closed when replacing the That is, even if the waste toner box 6 is not actually replaced, if the developer is dropped by applying vibration, it is possible to reduce the developer adhering to the vicinity of the inflow port 6a etc., and leakage can be suppressed. is there. When the dual purpose opening / closing cover is opened, the possibility that the waste toner box 6 is replaced is low compared to when the dedicated opening / closing cover 11 is opened, but the open / close cover is closed when it is opened. It is also possible to adopt a configuration in which vibration is given as the possibility of the waste toner box 6 being replaced being increased compared to the situation described above.

Next, a second embodiment of the present invention will be described. In the description of the second embodiment, components corresponding to the components of the first embodiment are denoted by the same reference numerals, and the detailed description thereof is omitted. Do.

This embodiment is different from the first embodiment in the following points, but configured in the same manner as the first embodiment in the other points.

FIG. 9 is an explanatory view of a vibration device of a sixth embodiment, which corresponds to FIG. 3 of the first embodiment.
In FIG. 9, in the copying machine U according to the sixth embodiment, the gear 12 is not provided on the opening / closing cover 11. An eccentric cam 61, which is an example of a vibration device and is an example of an eccentric member, is disposed on the front side of the waste toner box 6. The eccentric cam 61 is disposed to face the front wall surface of the waste toner box 6. The drive is transmitted to the eccentric cam 61 from a motor M1 as an example of a drive source.
Further, the bottom surface of the waste toner box 6 is supported by a conveyance belt 62 as an example of a conveyance member.
Further, on the front side of the upper surface of the waste toner box 6, a recess 6c as an example of a controlled portion is formed. A lock 63 as an example of a regulating member is movably supported by the recess 6 c between a fitted state shown by a solid line and a detached state shown by a broken line.
In the sixth embodiment, an open / close detection sensor SN1 as an example of a detection member for detecting the opening of the open / close cover 11 is installed.

  The eccentric cam 61, the conveyance belt 62, and the lock 63 are controlled by the control unit C. The control unit C includes an input / output interface I / O that performs input / output of signals with the outside. Further, the control unit C has a ROM: read only memory in which a program for performing necessary processing, information, and the like are stored. In addition, the control unit C has a random access memory (RAM) for temporarily storing necessary data. Further, the control unit C includes a central processing unit (CPU) that performs processing according to a program stored in a ROM or the like. Therefore, the control unit C of the first embodiment is configured by a small information processing apparatus, a so-called microcomputer. Therefore, the control unit C can realize various functions by executing the program stored in the ROM or the like.

The control unit C of the sixth embodiment has the following functions.
The open / close determination unit C1 determines whether the open / close cover 11 is opened based on the detection result of the open / close detection sensor SN1.
The vibration control means C 2 controls the eccentric cam 61 to apply vibration to the waste toner box 6. The vibration control means C2 of the sixth embodiment rotates the eccentric cam 61 for a preset period when it is detected that the open / close cover 11 is open. Therefore, with the rotation of the eccentric cam 61, the eccentric cam 61 intermittently contacts the side surface of the waste toner box 6 to apply vibration.

The loading and unloading control means C3 rotates the motor M2 as an example of the driving source forward and reverse according to the input to the operation unit UI to rotate the transport belt 62 forward and reverse to load and eject the waste toner box 6. Therefore, when it is input that the waste toner box 6 is attached on the operation unit UI with the open / close cover 11 open, the transport belt 62 is rotated forward to connect the waste toner box 6 to the drop path 3 Move it. In addition, when the user is instructed to remove the waste toner box 6 at the operation unit UI, the conveyance belt 62 is reversely rotated to convey the waste toner box 6 to a preset position near the opening / closing cover 11.
The lock control means C4 controls the lock 63 so that the lock 63 can be engaged with the lock 63 and the recess 6c of the waste toner box 6 in a fitted state (locked state) or in a disengaged state (unlocked state). Move it. The lock control means C4 of the sixth embodiment brings the lock 63 into the lock state when the waste toner box 6 is attached, and brings the lock 63 into the unlock state when an input for removing the waste toner box 6 is made.

Therefore, even in the copying machine U according to the sixth embodiment, the developer 21 attached to the outlet 3a and the like can be dropped by vibration.
Further, in the configuration of the sixth embodiment, the waste toner box 6 is taken in and out by the conveyance belt 62 in accordance with the input from the operation unit UI. Therefore, the replacement operation of the waste toner box 6 becomes easier than when the waste toner box 6 is manually put in and out. In particular, the transport belt 62 is operated in a state in which the open / close cover 11 is open, that is, after the waste toner box 6 is vibrated by the eccentric cam 61. Therefore, the waste toner box 6 is prevented from being removed before the vibration is applied, and the leakage of the developer is suppressed.

  Further, in the configuration of the sixth embodiment, when the lock 63 is in the locked state, the lock 63 is fitted in the recess 6 c, and the waste toner box 6 can not be taken out. Therefore, in a state where the power of the copying machine U is not turned on, the operator can not open the opening / closing cover 11 and can not take out the waste toner box 6 even when trying to take it out. That is, if the copying machine U is not powered on, the eccentric cam 61 does not operate even if the open / close cover 11 is opened, and if the waste toner box 6 is taken out as it is, the developer may leak out. In Example 6, the lock is locked, and the waste toner box 6 is prevented from being removed before vibration is applied.

The configuration for locking is not limited to the configuration exemplified in the sixth embodiment, and any configuration capable of restricting the removal of the waste toner box 6 may be employed. Moreover, although it is desirable to provide a lock mechanism, it is also possible to set it as the structure which does not provide a lock mechanism.
Moreover, although the eccentric cam 61 as an example of a vibration apparatus was used in Example 6, it is not limited to this. In the configurations of the first to fifth embodiments, the gears 12, 23, and 42 may be driven by a motor. Also, instead of the configuration of the eccentric cam 61, it is possible to repeat the on / off of the solenoid to apply vibration.

In FIG. 11, unlike the sixth embodiment, the vibration control means C2 of the seventh embodiment is different from the sixth embodiment in that the waste toner box 6 is not removed when the opening and closing cover 11 is detected. The eccentric cam 61 is operated in a preset period until it comes out of the dropping path 3.

(Operation of Example 7)
In the copying machine U according to the seventh embodiment having the above-described structure, the bellows 71 is disposed in the falling path 3 and the waste toner box 6 is moved even in the direction of disengaging as compared with the first to sixth embodiments. Only by the expansion and contraction of the bellows 71, there is a grace period until the waste toner box 6 is removed from the drop path 3. In the seventh embodiment, the waste toner box 6 is vibrated by the eccentric cam 61 during this grace period. Therefore, when the waste toner box 6 is removed, vibration is applied to the waste toner box 6 during conveyance by the conveyance belt 62 and before the waste toner box 6 is removed from the drop path 3. Therefore, in the seventh embodiment, as in the first to sixth embodiments, vibration is applied to the waste toner box 6 before the connection portion between the waste toner box 6 and the drop path 3 is removed. Therefore, the developer 21 attached to the outlet 3a and the like can be dropped by vibration, and the leakage of the developer is reduced.
