Title: Copying machine
Inventor: YOSHIUCHI KATSUHIRO
IPC: B41J15/16
Filed: 1995-01-10
Abstract: PURPOSE: To carry a copying sheet without being skew by aligning the tip of the copying sheet sent on a carrying path on a line orthogonally crossing its carrying direction and by rotating this at a circumferential speed slower than that of a carrying roller during carrying of the copying sheet. CONSTITUTION: The tip of a copying sheet is first stopped by a register roller 39 provided in a bypass carrying path D4 and the tip of the copying sheet is aligned on a line orthogonal to its carrying path. During carrying of the copying sheet, the roller 39 is rotated at a circumferential speed slower by a specified amount than that of a carrying roller 33 and a specified tension is always applied to the copying sheet between the carrying roller 33 and the register roller 39. Thus, skew shifting of the copying sheet from its carrying direction, that is, skew advancing of the copying sheet during being carried, is prevented. Therefore, jamming of the copying sheet is difficult to occur in a copying machine. Particularly, when a copying sheet is a large size cut sheet, the frequency of jamming is reduced.

IPC: F16H1/00
Filed: 1988-01-12
Abstract: PURPOSE:To make rotation transmissible with noncontact and prevent dust from occurring as well as to dispense with any lubricant by constituting two gears with a base made up of a nonmagnetic material and a permanent magnet where all tooth parts set their addendums down to the same type magnetic pole. CONSTITUTION:Either of two gears 10a, 10b consists of bases 11a, 11b and tooth parts attached to these bases, and all tooth parts are constituted of permanent magnets 12a, 12b setting their addendums down to the same type magnetic pole N. Consequently, an addendum in a tooth part of the gear 10a on one side and that of the gear 10b on the other being engaged with the former both are of the same type magnetic pole N, whereby there is produced repulsive force between these addendums, and thus rotational transmission is achieved without direct contact between tooth parts themselves. Therefore there is no fear that any dust attributable to the direct contact between these gears 10a and 10b might be produced, and at the same time, use of any lubricant for preventing this dust from occurring is not required at all. Accordingly, it is effectively adoptable to such a vacuum filming device or the like that is apt to degrade a product due to the dust and the lubricant.
