Title: Device for detecting tilted original
Inventor: TANI MASATO
IPC: G06K9/20
Filed: 1985-09-05
Abstract: PURPOSE:To detect a tilted original by supervising the time/length or the number of picture elements from the read start point on a main scanning line until the beginning of the original or from the end of the original until the read end point. CONSTITUTION:Since actual read width a'b' by an image sensor 5 in an optical reader is selected wider than the width ab of the original 4 by 2l, the presence of tilted feed is supervised by supervising the change in the left or right side length (l). The fluctuation of the time from the read start point on the main scanning line until the left end of the original and when the value exceeds a threshold value, an original tilt feed detection signal is generated. As the original 4, white paper is adopted and a read roller 7 is provided at the back of the read section of the original, then the start (left end) of the original or the tail end (right end) is detected easily in the reading in the main scanning direction by applying no reflection processing on the surface.

Filed: 1981-12-09
Abstract: PURPOSE:To surely perform the disk loading operation, by projecting and driving a controlling member which corresponds to the size of the disk in accordance with the output of a disk size judging circuit. CONSTITUTION:A fixed blocking plate 24 is installed to the central part of an opening and both ends of the opening is set in such a way that, when disk guide members 4 and 4' move to the closing direction and reach a prescribed location, they block the optical path of optical sensors and determine the minimum width of the opening.

When the disk guide members 4 and 4' reach a prescribed location and the blocking plate 24 blocks the optical path of either one of the optical sensors, the output of both gates becomes ''L'' level and the movement of the disk guide members 4 and 4' is stopped, and thus, the minimum width of the opening is determined.
