Description

  The present invention relates to a shredder capable of shredding processed products such as paper sheets.

  Conventionally, waste can be inserted into and removed from a housing that has a blade storage chamber that stores blades for shredding workpieces and a waste storage chamber that faces the shredder outlet of the blade storage chamber. Various shredders have been proposed. In such a shredder, the shredded material adhering to the inner surface of the blade or blade housing chamber may fall out of the shredded product when the shredded product is removed from the housing when the shredded product is discarded. The conventional shredder has an interlock system that allows the blade to operate only in the inserted state in which the waste is inserted so that the user can safely remove shredded waste adhering to the blade housing chamber. Many things have been devised.

And in order to prevent shredded scraps from falling further, it is also proposed to provide a movable body such as a shutter that shields shredded waste outlets from the shredded storage chamber when the scrap insert operates from the inserted state. Has been. Such a movable body can be configured to include a shutter having an L-shaped side view that rotates in accordance with the operation of scrapping, or by providing a lock member or spring near the shutter or the shutter. There has been known a structure (for example, see Patent Document 1) that constitutes a lock mechanism for locking the door in the closed position.

  However, what is set so that the blade can operate only in the inserted state with the waste inserted is certainly safe and effective for removing shredded waste, It is not something that can be prevented and the removed shredded waste must be cleaned in the same manner as shredded shredded waste.

  And when the shutter which can be rotated like a side view as described above is provided, when the shutter is rotated, it comes into contact with shredded waste or attached to the blade housing chamber, and the shredded waste May be dropped. In addition, the structure described in Patent Document 1 not only makes the mechanism vigorous and complicated, but also has a configuration in which the spring is always held in a pulled state when the shutter is maintained at the closed position. If the lock mechanism is damaged when the shutter is in the closed position, the shredder itself cannot be used.

  The present invention focuses on such problems, and provides a shredder that can effectively prevent unexpected dropping of shredded waste with a simple configuration.
