Title: Solid-state image pickup device
Inventor: AWAMOTO KENJI
IPC: H04N5/372
Filed: 1990-03-15
Abstract: PURPOSE:To secure a high resolution without extending the area of photodetectors by specifying intervals of photodetectors in the column direction with respect to the scan distance for one photodetector in the column direction. CONSTITUTION:Intervals of photodetectors in the column direction are set to (1+1/n)d where (d) is the scan distance for n-number of photodetectors in the column direction. When a photodetector 111 receives incidence light from a specific point at a specific time T1 and a photodetector 112 receives incident light from the specific point at a specific time T2, the photodetector 112 is d/4 short of the aperture position in the first T2/4 period of the time T2 which is the electric charge storage time of the photodetector, and the photodetector 112 is placed in the position, where reception of incident light from the specific point of the photodetector 111 is started at the time T1, in the second T2/4 period of the time T2, namely, at the time when a switch 212 corresponding to the photodetector 112 is turned on and electric charge storage of the photodetector 112 is started. Thus, the essential photodetector area is kept and a distinct image is obtained.

Abstract: PURPOSE:To accurately detect the direction of movement by providing photosensors and a grounding rod apart from and opposite to each other on a reflection roller which interlocks with a revolving roller which comes into contact with the floor and detects the direction of the movement, the distance between the grounding rod and the reflection roller being shorter than that between the photosensors and the reflection roller. CONSTITUTION:A reflection roller 53 is provided, which interlocks with a roller 36 which, in a suction opening substance 11, revolves in contact with the floor and detects the direction of movement. The reflection roller 53 has a shaft 48, which is rotatably held by bearings 48a, 48b. The roller 53 is also provided with photosensors 57a, 57b which are installed apart from and opposite to each other and a grounding rod 59 as a non-contact conductor. The distance L2 between the grounding rod 59 and the reflection roller 53 is shorter than that between the photosensors 57a, 57b and the roller 53. The static electricity in the reflection roller 53 is discharged by the grounding rod 59. Thus, discharge is prevented between the photosensors and the reflection roller, and the direction of movement is accurately detected without contact.
