Abstract

A reflection case is attached to respective LEDs of an exposure head. An inner wall of the reflection case is formed with a first low-reflection area (reflectance is 0.1), a high-reflection area (reflectance is 0.9), and a second low-reflection area (reflectance is 0.1). These reflection areas are formed in an optical-axis direction from a side of the LED. The reflection case is disposed such that a middle point between the LED and a photosensitive surface of an instant film is positioned within the high-reflection area. The light emitted from the LED is reflected on the inner wall of the reflection case to be applied to the photosensitive surface of the instant film without dispersion. Owing to this, the effective exposure head may be produced.
