Title: Structure for preventing rolling of keyboard
Inventor: SUZUKI AKIHIRO
IPC: G10H1/34
Filed: 1998-10-20
Abstract: PROBLEM TO BE SOLVED: To effectively prevent rolling of a key board, and to compactify a keyboard device as the whole. SOLUTION: A pair of guide parts 103, 104 projected in a laid direction of plural keyboards 20 and extended bandlikely to a hight direction are provided in a front part and a rear part of both side walls in a shaft supporting member 101 provided to be protruded in a rear end part of a chassis body 11. Respective sliding faces of the guide parts 103, 104 are brought into contact with inner side faces of a pair of flange parts in the keyboard 20 respectively to guide oscillation of the keyboard 20. Since rolling of the keyboard 20 is prevented to some extent in the rear end side of the keyboard 20 by this constitution, a guide area in the rear end is made smaller than conventional one. As a result thereof, front end heights of the keyboard 20 and the chassis are suppressed low to compactify the whole size of a keyboard device.

Title: Method for approximating positional data
Inventor: MORIYAMA HIROSHI
IPC: G06T5/00
Filed: 1990-11-05
Abstract: PURPOSE:To smooth a connection state between a straight line and a curve by adopting only a boundary point candidate for setting up the approximation accuracy of approximate position data to a certain positional data to a prescribed value as a boundary point when a dot shape has a boundary point on which a straight line is connected to a curve. CONSTITUTION:All of connection points between a straight line and a curve are adopted as boundary point candidates, and whether the value of a narrow angle be tween the curve and the straight line on the boundary point candidates is a prescribed value or not is decided and an element P2 more than the prescribed value is removed from the boundary point candidates. Whether the ratio of length of segments between the curve and straight line on the boundary point candidates is a prescribed value or not is decided and an element P4 more than the prescribed value is removed from the boundary point candidates. Furthermore, whether the whole shape formed by the straight line and the curve through the boundary candidate is a projected shape or not is decided, and a point P7 having no projected shape is removed from the boundary point candidates. Consequently, approximate position data in adjacent approxi mate sections can be smoothly joined, and while holding the approximate accuracy of an original graphic to the position data at a prescribed value, the original graphic can be reproduced.

Abstract: PURPOSE:To accomplish the uniformity of electrostatic charging and to prolong the life of an electrostatic charging device by comparatively simple constitution. CONSTITUTION:Magnetic particles Mgp are attracted and held on the outer peripheral surface 2a of a non-magnetic sleeve 2 by magnetic force of fixed magnets 5A-5D in the sleeve, and rotated in a direction shown by an arrow A in such a state. Then, the magnetic particles Mgp are carried to an opposed area 4 to a photosensitive body 3(electrostatic latent image carrier), and voltage is supplied from a power source 6 to the sleeve 2 in a state where the particles Mgp are uniformly brought into contact with the photosensitive body 3 by small contact force, thereby uniformly electrostatically charging the photosensitive body 3. It is also good to make it possible to rotate the magnet by which the particles Mgp are attracted in the sleeve 2 or to directly magnetize the outer peripheral surface of the sleeve. In the case that it is made possible to exchange the magnetic particles, the life is prolonged.
