Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention provides an electric razor of a type in which a scraping blade is movable along the side surface of a main body case, and the scraping blade can be protruded and stored in conjunction with the movement. Regarding.

(Prior art) In general, the closer to the end of the main case the scraper blade is placed, or the closer it is to the end of the main case, the less the case will get in the way, and when not in use, the main body case will not be in the way. The further inward from the edge of the case, the less likely it will be affected by a shock, such as when dropped, and damage can be prevented.

However, as shown in FIG.
1 is housed below the end of the main body case 63 where the main blade 62 is located, and the scraping blade 61 is configured to protrude below the main blade 62.

In addition, as shown in Figure 6 B, when using the scratching blade 6
4 is located near the end of the main body case 63.

However, in the former electric razor, the scraping blade 61 is located below the main body case 63 when protruding, that is, it is located considerably inward from the end of the main body case 63. The problem was that the edges of the device got in the way and made it difficult to use.

In addition, in the latter type, the scraping blade 64 can be placed close to the main blade 62, so it does not have the drawbacks like the one in Figure A, but since the scraping blade 64 is always protruded to the outside. , there was a risk of damaging the blade.

Therefore, as shown in Japanese Patent Application Laid-Open No. 56-57477,
A device has been proposed in which the scratching blade is slidable and is projected above the main blade when in use.

(Problem to be Solved by the Invention) However, since this electric razor is cantilever supported by a plate-shaped support member, there is a problem in supporting the scraping blade when it projects upward, and the scraping blade may wobble when used. , difficult to use,
Additionally, there is a risk of damage due to contact with other objects.

In addition, since the kerf blade is structured so that the kerf blade is exposed both when it is extended and when it is stored, it is easy for the scraps cut when the main blade is used to get into the support part of the kerf blade.
If there is significant adhesion, there is a problem that the scraping blade may not be able to move smoothly.

The present invention was proposed in view of the above circumstances, and its objectives are to reduce the wobbling of the scraping blade, reduce damage caused by contact with other objects, and prevent hair from entering and moving. We are here to provide you with a smooth electric razor.

(Means for Solving the Problems) The present invention provides an electric razor in which the scraping blade is movable along the side surface of the main body case, and in conjunction with the movement, the scraping blade can be protruded and stored. A scuffing blade case is slidably provided on the side surface of the main body case, and includes a scuffing blade storage portion for storing the scuffing blade and a driving means for protruding and driving the scuffing blade. The above object is achieved by configuring the device so that when the blade case is moved toward the end of the main case, the scraping blade protrudes laterally from the scraping blade housing.

(Function) In the present invention, when the scraping blade is not in use, the scraping blade is housed in the scraping blade case, and when the scraping blade case is moved from this state toward the end of the main case, the scraping blade moves laterally. By supporting the scraping blade within the scraping blade case, it reduces the wobbling of the scraping blade, makes it difficult for hair to adhere to the scraping blade, and makes the movement of the scraping blade smooth. .
