Description

[Detailed Description of the Invention] The present invention relates to a pencil sharpener and its shavings case. Conventional pencil sharpeners, especially small electric pencil sharpeners with vertical pencil insertion, are equipped with a shavings case that can be attached and removed from the side of the main body. The blade holder is separated from the bottom plate, and when the shavings case is removed, the shavings remaining at the bottom of the blade holder may be scattered, which is a major cause of reduced usability.

The present invention has been improved in view of the above-mentioned drawbacks, and includes a bottom plate extending from the shavings case that covers the back surface of the scrap receiving plate at the bottom of the blade holder, and a scrap receiving plate on the edge of the bottom plate in the extending direction. By forming ribs extending toward the back surface of the plate, all the shavings remaining on the shavings receiving plate are stored in the shavings case, and scattering of shavings when the shavings case is removed is minimized. This is the purpose.

The present invention will be explained below with reference to an embodiment of a small electric pencil sharpener. 1 is the main body of the pencil sharpener;
It consists of a cutting part 2 having a substantially cylindrical shape and a power supply driving part 3 having a substantially rectangular parallelepiped shape. A blade holder 5 equipped with a cutting blade 4 rotated by a driving electric motor (not shown) is installed inside the cutting part 2, and a blade holder 5 is installed inside the cutting part 2.
is provided with a shavings case 6 which is detachably attached to one side and covers the blade holder 5.

A scrap receiving plate 7 is formed at the lower part of the blade holder 5 to prevent cutting debris from entering the drive unit, and the bottom plate 8 of the scraping case 6 wraps around to cover the back surface of the scrap receiving plate 7. It is formed to extend. That is, a substantially semicircular notch 9 having a width B is provided in a part of the bottom plate 8, and the notch 9 is made to match the back surface of the circular waste receiving plate 7 having a diameter A. A rib 10 extending toward the back surface of the waste receiving plate 7 is formed at the end edge of the bottom plate 8 in the extending direction, including the periphery of the notch 9. Of course, the width B and the diameter A satisfy the relationship A>B.

Next, to explain the function of this invention, after cutting is completed,
Before detaching the shavings case 6 from the main body 1, the shavings accumulated on the swarf receiving plate 7 are moved toward the bottom plate 8 of the shavings case 6 by lightly vibrating the main body 1. and then the main body 1
When the shavings case 6 is removed from the shavings case 6 and the shavings are dumped outside, the ribs 10 provided on the bottom plate 8 prevent the shavings from scattering from the shavings case 6, and the shavings are not disposed of inside the main body 1 as in the conventional case. There is no need to worry about flying shavings.

As described above, the present invention has a blade holder equipped with a cutting blade rotated by a driving electric motor, a semi-cylindrical shavings case that covers the blade holder and is detachable from one side of the main body, and a lower part of the blade holder. A pencil sharpener comprising a circular shavings receiving plate formed on the shavings case, and a bottom plate extending from the shavings case to cover the back surface of the shavings receiving plate, wherein a substantially semicircular notch is formed in the bottom plate. The width of the notch of the lever is smaller than the diameter of the scrap receiving plate, and a U extending toward the back surface of the scrap receiving plate is provided at the end edge of the bottom plate in the extending direction.
By forming the letter-shaped ribs, we can improve the shavings collection mechanism with a simple structure and provide a pencil sharpener that is extremely easy to use. This has the effect of increasing the shavings storage capacity of the shavings case itself.
