Abstract

PURPOSE: To ensure a uniform luminous intensity for the area to be illuminated by a lamp, by turning the lamp having a light transmission part to give an illumination in one direction in order to simplify the mechanical constitution as well as to miniaturize the main body of an illuminating device and at the same time adjusting the lamp light.
CONSTITUTION: The original 3 on the transparent platen is illuminated by the illuminating lamp 9 and then irradiated onto a photoreceptor via the rotary mirror 72 and the fixed mirror 82. The lamp 9 consists of the part having the reflecting film 10 inside the glass tube 9a and the opening part 9b having a degree of 90°, and installed with the part 9b turned to the original 3. Then the lamp is turned in synchronization with the mirror 72 provided the opening part 9b toward the original 3 and illuminates the originals successively. The light exposed from the original is reflected by the mirror 82 to be supplied to the luminous intensity sensor 11. With the detection of the sensor 11, the lamp 9 is controlled to secure a fixed level of luminous intensity.
