Title: Stencil printing apparatus
Inventor: IROKAWA SHIGENOBU
IPC: B41L13/18
Filed: 1992-02-21
Abstract: PURPOSE:To supply a moderate amount of ink to an ink supply device and to properly print by providing a receiver on a plate cylinder in such a manner that it faces the printer body to transfer a light, radio wave or magnetic signal for control. CONSTITUTION:During the prescribed print, ink in an ink reservoir 32 is being gradually spent and decreased so that an ink detection pointer 71 in an ink sensor section 54 becomes non-contact with the ink in the ink reservoir 32. Consequently, electrostatic capacity detected by the pointer 71 decreases and a pulse width of an output signal from monostable circuit 54B in an ink sensor section 54 becomes short, thereby the level of an output signal from a phase comparator section 54C becomes lower. In response to this, an emission controller circuit 56B in a transmitter section 56 outputs an emission drive signal and an emission device 56A emits the light. When a receiver device 57A receives the light signal, a receiver circuit 57B receives the receiving signal and outputs a control signal for controlling a drive circuit 82 to set it on-state. Upon receiving the control signal, the drive circuit 82 outputs a drive signal to a electromagnetic clutch 72 via a pair of electric connecters 78b, 78a.
