Title: Paper feeder
Inventor: KITAZAWA MASAHIRO
IPC: B65H1/14
Filed: 1982-01-27
Abstract: PURPOSE:To bring paper and a paper feed roller into contact with each other under predetermined pressure in the paper feeder of a copier or the like, by  causing first and second magnets to face each other to repulse each other as a  paper feed tray is set in the body of the copier or the like. CONSTITUTION:When a tray 1 is inserted to a set position, first magnets 6 provided on the bottom plate 2 of the tray face second magnets 11 on a base plate 10 so that the tray integrally fitted with the first magnets is inclined about the rear end of the tray by the repulsive force between the first and the second magnets. Consequently, the top of paper P comes into contact with a paper feed roller 14 under pressure necessary to sequentially feed the paper by the rotation of the roller. The prescribed contact pressure is surely applied between the paper P and the feed roller 14 by such a simple construction that the magnets 6, 11 are provided on the tray 1 and the base plate 10. As a result, malfunctions do not occur.

Title: Carrier vehicle
Inventor: SUESHIGE HIROSHI
IPC: B60B37/00
Filed: 1999-01-19
Abstract: PROBLEM TO BE SOLVED: To provide a carrier vehicle having no differential gear, permitting an easy change of direction of travel by hand in a condition where an electric motor or an engine thereof is stopped. SOLUTION: Upon engagement of a head portion 53b of a headed pin 53 with a bolt 66, a front wheel 2R starts to rotate together with a front axle 44 as indicated by an arrow 2. This permits a carrier vehicle to travel forward. As a result, the front wheel 2R can rotate as indicated by an arrow 3 keeping the front axle in a standstill. Namely, within the range of an angle θ (approximately 300 deg.) until the bolt 66 comes in contact with the head portion 53b, the front wheel can rotate counterclockwise. Since driving wheels can idle within a predetermined angle, turning or a change in direction of travel is permitted by idling the driving wheels. As a result, operability of the carrier vehicle can be greatly improved.
