Abstract
A pulse signal is detected from an encoder signal of a rotary encoder. The detected pulse signal is used as a signal for controlling a light exposure timing of a line type light exposure head and is used for detecting a transport speed of an instant film. The light exposure head sequentially performs light exposure for a line image on the transported instant film in synchronization with each pulse signal detected from the encoder signal, and a density correction unit corrects an amount of light emission of the light exposure head depending on the transport speed of the instant film.
