Abstract
PURPOSE: To make possible applying of exposure evenly for the specified time to a sheet form photoreceptor superposed on the original by turning the tubular shield body provided with a slit form gate opening in one direction.
CONSTITUTION: The light source device is constituted by a tubular light source 8 such as high pressure mercury vapor lamp and a reflecting plate 13 which reflects the rays emitted from said light source 8 toward a top cover 4 which is openable from the housing 3 placed with the sheet-form photoreceptor 6. A tubular shield body 12 which is so turnably disposed as to enclose this light source device is provided with a slit form gate opening 22 along the axial direction to become its turning center so that the sheet-form photoreceptor 6 is exposed when it opposes to the slit-form gate opening 22 by turning the shield body 12 in the fixed direction. Hence, the occurrence of uneven exposure is obviated and the device may be constituted compactly.
