Abstract: PURPOSE:To surely remove both a level H noise overlapping with the level L of an input signal and a level L noise overlapping with a level H by setting or resetting a 1st latch circuit according to the input signal and the logic of an output signal from a 2nd latch circuit. CONSTITUTION:When both the input signal (b) and the output signal (d) are at level H, a setting gate 6(AND circuit) setting the latch circuit 3 is provided. When the input signal (b) changes from H to L level and a clock signal (a) falls during a level L session, the output signal (c) of the latch circuit 3 also changes to level L.

Title: Paper retainer for paper aligning device
Inventor: MIURA ISAMU
IPC: B41J13/10
Filed: 1985-09-20
Abstract: PURPOSE:To prevent paper sheets from being wrinkled due to rubbing thereamong, by swingably journalling a slide plate secured onto the lower surface thereof with a lead spring-like retainer piece to the upper end of a swing support arm through the intermediary of a hinge structure. CONSTITUTION:After the paper retaining position being adjusted, paper sheets (b) is slid down along a slide plate 13 onto the paper feed surface A of a paper aligning device 1. When a sheet detector 18 detects the presence of paper sheets (a), a control motor 16 rotates a cam 15 so that the slide plate 13 lowers a retainer piece 17, and therefore, when the paper sheets (a) slide on the upper surface of stacked paper sheets, the retainer piece 17 checks one end of paper sheets therebelow, and therefore, no defects such as, for example, paper slips and paper creases occur due to paper sheets sliding thereamong. Then, when the sheet detector 18 detects no pressure of paper sheets (a), the cam 15 raises the paper retanier piece 17 so that trailing ends of newly set paper sheets (a) are dropped below the paper retainer piece 17, and then one edge section of the paper sheets are retained when the detector 18 detects the presence of paper sheets at the next time, thereby it is possible to stack the paper sheets (a), uniformly, with the repetition of the above-mentioned steps.
