Switch 23, down switch
24, an emergency stop button 25, etc. are provided.

Further, a caster 26 is attached to a lower portion of the bottom plate 1a of the casing 1.

Next, the usage will be described. The casing 1 is moved to an arbitrary position in an office, for example, by a caster 26, and installed as a trash can. In this case, handle
By manually turning 19, the gear shaft 16 is rotated via the bevel gear 18, and all the hooks 14 fixed thereto are simultaneously rotated upward to lock the locking claw 14a and the frame 20. To release.

As a result, the lid 2 becomes free with respect to the casing 1, so that the lid 2 is rotated upward by hand with the hinge 13 as a pivot, thereby opening the upper opening 1b of the casing 1. . In this state, the compression member 5 by the link mechanism is in a contracted state, and a space for accommodating dust is formed above the press plate 4 in the cylinder 3. Therefore,
The garbage bag 27 is put into the cylinder 3 through the opening 1b and set in the space above the press plate 4.

The garbage bag 27 is set in the cylinder 3 in this manner, and the apparatus is used as a trash box with the lid 2 opened, and trash such as paper is put into the trash bag 27 through the opening 1b. When the door 22 is opened and it is confirmed that the garbage bag 27 is full of garbage, the lid 2 is closed by hand, and then the handle 19 is turned in the opposite direction to when the lid 2 is opened. The hook 14a of the hook 14 is framed by the opposite operation.

If another empty garbage bag 27 is set in the cylinder 3 on the garbage bag 27 and garbage is put into the garbage bag 27 in the same manner as described above, and the garbage bag 27 is full of garbage, ,
In the same manner as described above, the compression member 5 is extended by the link mechanism, and the press plate 4 is pressed against the lid 2 to compress the dust together with the dust bag 27.

In this way, the garbage is pressed two to three times, for example, and when the inside of the cylinder 3 is filled with the two or three compressed garbage bags 27, the opening / closing door 22 is opened and the garbage is opened. The garbage for the second to third compressions is all taken out simultaneously with the garbage bag 27.

In the first embodiment, the link mechanism constituting the compression member 5 is raised and extended to a nearly vertical state at the lower center of the press plate 4 in the extended state. In the second embodiment, the entirety of the compression member 5 constituted by the link mechanism can be raised so as to approach one of the right and left sides, in the illustrated example, to the right side, to be in the expanded state.

In this case, the lower and upper 2
One lower end of the arm 5a is fixed to the side of the cylinder 3, and the other lower end moves to the other side. In particular, the lower arm 5a is the same as in the first embodiment. There is no need to provide a screw shaft provided with a screw portion in the opposite direction and synchronize the two arms 5a and simultaneously move them to the center side. It is only necessary to install a mechanism for moving the other arm 5a, so the structure is simple. And the movement is more reliable.

In the second embodiment, a handle 28 is provided on the upper portion of the lid 2 to facilitate opening and closing of the lid 2.

In both the first and second embodiments, a combination of a shredder and a shredder may be considered. In this case, the shredder may be opened by opening the lid 2 to open the upper opening 1b of the casing 1, and the shredder may be placed on the shredder.
Here, the discharge port of the shredder may be made to face. In this case, it is conceivable to provide an opening / closing means such as a shutter in the through hole so that the lid 2 can withstand the pressing pressure.

In any case, the trash cut by the shredder can be reliably and automatically put into the trash bag 27.
