Abstract

PURPOSE: To decide whether the print head moves accurately or not, by comparing the actual movement quantity of the print head with the designated movement quantity determined by the number of pulses input to the pulse motor.
CONSTITUTION: Pulses to drive pulse motor 15 are supplied to counter 14 through sluing circuit 11. In this counter 14, the number of pulses required for movement of the print head of a prescribed distance is set previously. The actual movement quantity of the print head which is detected by sensors SL and SR provided at both ends of the movement range of the print head is counted by counter 14. This count value is compared with the set value of counter 14; and if they coincide with each other, it is decided that the print head has moved accurately by a prescribed distance. Thus, it is decided whether the print head moves accurately or not.
