ONE SHEET DRAWING CLIP WITH SENSOR, METHOD FOR HOLDING AND SPECIAL PURPOSE SHEET

摘要

PROBLEM TO BE SOLVED: To orderly draw only an uppermost sheet from a plurality of held sheets in the state of closing a holder by forming an upper one side of the holder in a two-step structure of a front contact sheet part and a rear contact sheet part formed in a rotatable roller, a hard cylindrical shape, a round bar shape or the like having a small frictional resistance. ;SOLUTION: A front contact sheet part roller 1 having a sensor 8 mounted by a rotary switch unit and a rear contact sheet part roller 2 are supported in parallel to an upper one side D of a holder 5 by axial bars 1a, 2a. At the time of drawing one uppermost sheet, the sheet is grasped and drawn in the state the holder 5 remains closed in the state that a clip body is fixed. Then, the rollers 1, 2 are simultaneously rotated. Further, when the sheet is further drawn so that the sheet is released from the roller 2, the roller 2 is stopped rotating. The roller 2 becomes a stopper for urging a second sheet and retaining it in the holder 5. Thus, only the uppermost sheet can be orderly drawn.;COPYRIGHT: (C)1999,JPO
