Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an improvement in a shredder used for shredding unnecessary documents and the like into chips.

BACKGROUND ART AND PROBLEMS There is a conventionally used shredder in which paper shredding cutters are disposed between substantially parallel opposing walls and substantially parallel to each wall. In this type of shredder, the distance between the opposing wall and the cutter is made as small as possible in order to reduce the overall size of the shredder. As a result, due to the action of static electricity applied to the paper waste when it is shredded by the cutter, the paper waste adheres to the opposing wall, which in turn causes the paper waste to become stuck between the cutter and the opposing wall, reducing the shredding ability of the cutter. There was a problem with getting it done.

SUMMARY OF THE INVENTION An object of the present invention is to provide a shredder that solves these problems and allows a cutter to operate smoothly without becoming clogged with paper waste after shredding.

Means and Effects for Solving the Problems The object of the present invention is to provide the above-mentioned shredder, that is, a shredder in which a paper shredding cutter is disposed between substantially parallel opposing walls and substantially parallel to the walls. , is achieved by adding a member between the opposing wall and the cutter that can be easily deformed or vibrated. That is, according to the present invention, a shielding member is disposed between each of the opposing walls and the cutter to shield at least a portion of the opposing walls from the cutter,
The shielding member has a main body made of a flexible material and a part fixed to the main body and made of a rigid material, and the upper end of the shielding member is located above the lower end of the cutter. A shredder is provided which is characterized by: When such a shredder of the present invention is used, the paper waste shredded by the cutter does not adhere to the opposing wall but to the shielding member covering the opposing wall, so that the paper waste is By deforming or vibrating the shielding member, the attached paper waste can be easily removed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings in order to further clarify the structure, operation, and effects of the shredder of the present invention.

Embodiment FIGS. 1 and 2 show a typical embodiment of the shredder of the present invention. In the figure,
Reference numeral 1 denotes a housing that defines the entire shredder, and a paper shredding cutter 3 is disposed approximately parallel to the opposing walls 2 and 2' of a chassis provided within the housing. (See especially Figure 2). Below this cutter 3,
A waste storage member 4 is arranged to store paper waste that falls after being shredded by the cutter. As shown in the figure, a sensor 5 is generally installed in this waste storage member 4 to stop the operation of the cutter 3 when paper waste 6 is received to a predetermined position and the waste storage member is full. It's summery.

Here, the feature of the shredder of the present invention is that, as shown in the figure, there is a shield between each of the opposing walls 2, 2' and the cutter 3 to shield at least a part of those opposing walls from the cutter 3. The member 7 is provided. More specifically, this shielding member has a main body part 8 made of a flexible material such as plastic film, and an overhang part 9 fixed to the main body part and made of a rigid material such as hard plastic or metal. In the embodiment shown in the figure, the upper end of the shielding member 7 is attached to the upper end of the opposing walls 2, 2' via the clip 10, and this embodiment is advantageous in that the shielding member can be easily attached. It is. However, the upper end of the shielding member 7 may also be joined to the opposing walls 2, 2' at a lower position. However, the upper end of the shielding member 7 should be located above the lower end of the cutter 3. Note that the lower end of the shielding member 7 is as shown in the figure.
Preferably, it is located within the debris storage member 4.

When the shredder configured as described above is operated, the paper waste shredded by the cutter 3 adheres to the shielding member 7 due to static electricity when the cutter is reversed (in the conventional shredder, it directly adheres to the opposite wall), and finally , the paper waste 5 is removed from the shielding member 7
This will clog the gap between the cutter 3 and the cutter 3. However, in this case, when the overhang 9 is moved by hand, the main body 8 to which the overhang is fixed is easily deformed or vibrated. At this time, since the upper end of the shielding member is above the lower end of the cutter, the paper waste stuck between the cutter and the shielding member is swung by the deformation or vibration of the shielding member, and the paper scraps are swung into the waste storage member 4. be dropped into the

Effects of the Invention As can be understood from the above explanation, in the shredder of the present invention, paper waste accumulated on both sides of the cutter is easily removed by moving the shielding member and stored in the waste storage member. . Therefore, even if the distance between the opposing walls on which the cutters are disposed is small, the shredding ability of the cutters can be effectively demonstrated. In addition, if the distance between the opposing walls is small, and therefore the width of the waste storage member is small, paper waste may get on the full sensor (such as the one shown at 5 in Figure 1), and as a result, Although a bridge of paper waste may be formed across the top of the waste storage member before the paper waste is sufficiently accommodated in the waste storage member, the shielding member of the present invention also functions to press down the full sensor from above. , it also has the effect of preventing the formation of such debris bridges.
