Filed: 1990-09-21
Abstract: PURPOSE:To enable time for switching operation to be shortened by a method wherein means which makes operation for switching to an ordinary adjacent specific position omit a duplicate operation is provided to the switching operation to be performed at an adjacent specific position. CONSTITUTION:Pressure contact of a slide gear 44 is released by 10 steps reverse rotation and 3 steps normal rotation under a state in which a carriage is at a preliminary discharge position (D), and the side gear 44 and the carriage 2 come capable of being transferred. Then, the carriage 2 is transferred to a cap position (C) and thereafter, reverse rotation and normal rotation of a drive motor are omitted. This is because the slide gear 44 is engaged with a sheet feeding output gear both at the preliminary discharge position (D) and at the cap position (C), and the state performed at said preliminary discharge position (D), in which pressure contact of the slide gear was released is maintained. Then operation for releasing again the pressure contact at the cap position (C) becomes unnecessary.

Inventor: ISHIKAWA MASAAKI
IPC: B21B3/02
Filed: 1995-09-28
Abstract: PROBLEM TO BE SOLVED: To manufacture a dull finished stainless steel sheet excellent in antidazzle characteristic and uniformity of color tone by rolling a stainless sheet using work rolls on which random pattern without directivity is applied and only the surfaces of projecting parts of the pattern is dull worked. SOLUTION: First, the random pattern without dirctivity is formed on the surface of the work rolls by photoetching method. Next, the surface is roughened by applying dull working only to the projecting part 2 of the random pattern of the work roll, for example, by electric discharge machining. And, its mean surfaceroughness is ranged in 2-15μm and the depth of the recessed part 1 of the pattern provided on the surface by an etching method is ranged in 20-200μm. Because the ruggedness by etching is imparted to the dullfinished stainless steel sheet which is manufactured using such work rolls, antidazzle characteristic is greatly improved and, because the ruggedness by etching are enough deep, the change in the projecting and recessing shape and the change in the color tone which are transferred on the surface of sheet are small even when roll wear progresses to some extent.

Title: Document separating mechanism of automatic document feeding device
Inventor: HARADA HIROYUKI
IPC: G03G21/00
Filed: 1997-09-02
Abstract: PROBLEM TO BE SOLVED: To prevent curl of the document front end, and reduce a driving load by intermittently driving an actuating lever installed on a rotary shaft of a driving roller through a one-way clutch, by a cam. SOLUTION: A one-way clutch 56 transmits driving force so that a rotary shaft 451 of a driving roller 45 rotates in the arrow direction when an actuating lever 57 is actuated in the arrow direction, but does not transmit the driving force to the rotary shaft 451 of the driving roller 45 when the actuating lever 57 is actuated in the opposite direction of the arrow direction. On the other hand, since a cam 55 has an elliptic circular cam surface 551, when a separating roller 41 rotates once, the actuating lever 57 swings twice. Therefore, the rotary shaft 451 of the driving roller 45 connected to the actuating lever 57 through the one-way clutch 56, intermittently rotates in the arrow direction. Therefore, a separating belt 47 is intermittenly actuated in the arrow direction, and intermittenly changes a contact surface with a separating roller 43.
