Title: Printing machine
Inventor: SHINNO KEIJIROU
IPC: B41F33/14
Filed: 1981-07-31
Abstract: PURPOSE:To enable quiet and high speed printing by operating an electromagnetic type spring clutch with outputs of first and second monostable circuits for determining the position and time of printing which is triggered by a sheet paper detection signal of a photoelectric conversion element. CONSTITUTION:When a sheet paper gets in contact with a detection contactor 14 and turns a shielding plate 29 to intercept the optical path, negative pulses are generated from the photoelectric conversion element. This signal triggers a monostable circuit via an amplifier and outputs pulses corresponding to the delay time for the specified width, namely the printing position. With the rising of the pulses, another monostable circuit is triggered to operate an electromagnetic spring clutch for a specified time. This allows a lever 44 to be pulled with a coil 49 and the tip thereof separates from a step 42b of a cylindrical cam 42. A coil spring 43 winds around a power shaft and a rotary shaft 18 and a print wheel turns for a specified time and then, returns to dump the printed sheet paper into a box. This makes possible a simple construction and the performance of quiet and high speed operation.
