Title: Printing device
Inventor: KASHIWAGI TAKASHI
IPC: B41J19/18
Filed: 1988-09-16
Abstract: PURPOSE:To ensure that the abnormal action of a carrier is detected even during printing by providing an identification device which compares a count value which is read by a count value reading device with a setting value established in advance and identifies the normality or abnormality of a carrier action. CONSTITUTION:An incremental and decremental counter 24c is incremented by a pulse to be connected to a carrier motor 27 in response to the movement of the carrier 36 in one direction. At the same time, the incremental and decremental counter is decremented by a pulse to be connected to the carrier motor in response to the movement of the carrier in the other direction. If the carrier operates normally, the physical position of the carrier matches the count value of the counter constantly. This matching is determined when the carrier passes through a position detected by a home position sensor 31. That is, the home position sensor reads the count value of the incremental and decremental counter when the sensor detects the passage of the carrier, and compares the count value with a setting value established in advance. If the difference between the count value and the setting value is wide, the abnormality of the carrier action is identified.

Abstract: PROBLEM TO BE SOLVED: To increase the sampling frequency of data lines and to incorporate drivers into the active matrix substrate by providing plural series of data side driving circuits and properly shifting the phases of the input signals to these circuits. SOLUTION: A shift resister 501 controls the opening and the closing of analog switch groups 320, 323 and 327.
