Provided is an image exposure device capable of recording a favorable image and capable of decreasing the size of the device. An image exposure device (10) includes an image display device (12) having pixels (13), a photosensitive recording medium support portion (21) that supports a photosensitive recording medium (14) for recording an image of the image display device (12) in a state in which an exposure surface (14A) of the photosensitive recording medium (14) faces the image display device (12), and a transmitted light control portion (16) that is provided between the image display device (12) and the photosensitive recording medium support portion (21) and is formed by laminating three or more layers of transmission members (100) that have a plurality of openings (102) formed therein and transmit only light incident on the openings (102).

A film cover covers an exposure surface of a film unit to lighttightly block an exposure opening and is ejected from a discharge port. A bending guide groove is formed on the outside of an accompanying prevention rib in a width direction of a cover member along the accompanying prevention rib. The bending guide groove tilts a side edge portion, which is a distal end portion of the film cover, and the portion outside the accompanying prevention rib, in a protruding direction of the accompanying prevention rib. Since the side edge portion is bent by the bending guide groove, the both side edges portions do not engage with the discharge port, and the film cover can be ejected smoothly from the discharge port.

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.
