摘要： PURPOSE:To enable uniform grinding, by providing an elastic plate, the tip of the lower portion of which is put in pressure contact with the inside of the guide groove of an electric sharpener for a cutting tool and which forms an acute V- groove in cooperation with the inside of the guide groove, to stabilize the guiding of the cutting tool and keep the contact pressure between a grindstone and the cutting tool constant. CONSTITUTION:A motor 10 and a grindstone 11, which is rotated by the motor, are provided in the case 9 of an electric sharpener for a cutting tool. The sharpener has a guide groove 12 on a portion at the grindstone 11. The cutting tool is inserted into the guide groove 12. The sharpener also has an elastic plate 13, the tip of the lower portion of which is put in pressure contact with the inside 15 of the guide groove 12 and which forms an acute V-groove in cooperation with the inside 15. When a kitchen knife is inserted in the guide groove 12, the cutting edge of the cutting tool is pushed on the inside 15 of the guide groove by the oblique portion 13a of the elastic plate 13 so that the cutting edge does not unstably move. When the kitchen knife is pulled along the guide groove 12, the cutting edge is neatly ground by the edge of the grindstone 11 so that the angle of the cutting edge is made uniform.

摘要： PURPOSE:To prevent the folding of recording paper at the terminal part thereof, by attaching a dust protective cover to an apparatus internal mechanism to the contour of an apparatus in a revolvable manner and making it possible to use the same as the guide of recording paper in an open state. CONSTITUTION:A pivot shaft 11 is attached to the cont our 10 of an apparatus as the center of rotation in a revolvable manner and a dustproof cover 9, which prevents dust from penetrating into the apparatus when the apparatus is not operated, is provided to said shaft 11. The pivot shaft 11 is set so that a part of the dustproof cover 9 is contacted with the contour 10 but the revolution beyond that is limited when the dustproof cover 9 is revolved and brought to a state almost flushing with a paper guide table 12. When the printing apparatus is used, the dustproof cover 9 is revolved while recording paper 1 is inserted between a platen roller 2 and a roller 4 and a platen is rotated to perform the feed of the recording paper 1 and, thereafter, a pen 5 is protruded and retracted, while the platen is rotated to the A-direction, to perform printing on the recording paper. At this time, the terminal part of the recording paper 1 is held by the aforesaid dustroof cover 9 to be prevented from folding.

摘要： PURPOSE:To prevent damage from occurring due to the loss or dropping-off of the cover of an electric sharpener, by supporting the cover on the body of the sharpener so that the cover can be optionally turned back, and by providing a pushing operator for a power switch, on the surface of the sharpener body, with which the cover is placed in contact. CONSTITUTION:A grindstone is housed inside one side of the body 5 of an electric sharpener and a guide groove 6 is provided over the grindstone so that a sharpening section 7 is constructed. The rear end of a cover 8 for the sharpening section 7 is pivotally coupled to the body 5 by a shaft 9 so that the cover can be turned back around the shaft as a fulcrum and overlaid on a surface 10 of the body 5. A pushing operator 11 is protruded from the surface 10, on which the cover 8 can be overlaid, so that the operator is put into operation by the cover. When the sharpener is not in use, the cover 8 is placed over the sharpening section 7 to protect it. When the sharpener is put in use, the cover 8 is turned back to function as a switching panel.
