Inventor: MASUDA KAZUMI
IPC: G03B27/72
Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To provide an original edge sensor that can surely detect the tip of a moving original. SOLUTION: A groove 41, nearly in parallel with a moving direction A1 of an original, is formed on the surface of a rear member 21 located opposite to a light-receiving section 23 and a light source 24 in the case of viewing a reference position PR, in an original reader provided with the original edge sensor 1. A sensing section 24 senses the shadow of an original tip produced in the groove 41 on the basis of data of a reflected luminous quantity from a light-receiving element 26 for receiving reflected light from the groove 41 on the rear member 21 in the light-receiving section 23 to detect a timing, when the original tip reaches the reference position PR on the basis of the sensing result of the shadow. Thus, the original tip can be detected surely.  A data storage section 31 controls a storage start timing of the data of the reflected luminous quantity from all light-receiving elements 26 of the light- receiving section 23, in response to the arrival timing of the sensed original tip to the reference position. Accordingly, the shadow of the original tip can be eliminated from an image that is the result of reading the original.

Title: Information read and/or input device
Inventor: SHINJO KATSUHIKO
IPC: G11B9/00
Filed: 1990-09-19
Abstract: PURPOSE:To more accurately read and/or input information by controlling a probe not to generate angular parts in its turn-around scanning course on a sample surface. CONSTITUTION:A driving means 107 is controlled not to generate angular parts in the turn-around scanning course on the sample surface (recording layer) 101 by the probe (electrode) 102. That is, a scanning locus 101b of the probe electrode 102 on recording pits 101a by an XY-direction scan driving circuit 109 is smoothly turned around at scanning turning points. Since no angular parts take place in the locus of reciprocating motion of the probe, there are no spots of sudden changes in speed in the scanning locus, and the occurrence of minute vibration that is apt to occur in such speed suddenly change parts is prevented. Consequently, a linear scan is feasible without any distortion and deviation in the course on both outward and return routes, and more accurate recording and reproducing can be carried out. By this method, the accurate read and/or input of information is realized.
