Abstract
An encoder sensor is mounted on a printhead and optically reads an encoder film. And a number of pulses of a pulse signal proportional to a moving amount of a printhead is counted and stored as a count value in a memory within multiple ICs. The count value stored in the memories is reset while the pulse signal outputted from the encoder sensor is blocked by a gate or while a region other than near a boundary between a penetration region and a non-penetration region of the encoder film is being read.
