Abstract
PURPOSE:To make it possible to detect the widthwise position of a sheet without using marking, by laying a projection lens facing the sheet and a sensor so as to sufficiently cover variations in the travel position of the sheet. CONSTITUTION:An illumination lamp 14 is located being shifted from the optical axis of a lens 19 and irradiates light onto a sheet 11 through an window 12a in an upper plate 12. Reflected light from the sheet 11 is received by a linear image sensor array 16 through a projection lens 15, and a signal processing circuit 20 processes a signal delivered from the sensor array 16. Thus processed signal is fed, on one hand, from two output terminals 21, 22 as two detection signals S1, S2 and is fed, on the other hand, from a terminal 23 as an illumination lamp light adjusting signal S3 which is applied to a light adjusting drive circuit 24, and accordingly, the drive circuit 24 controls a power applied to the lamp 14.
