Title:
PROGRAM SIGNAL GENERATING DEVICE
Document Type and Number:
Japanese Patent JPS59189408
Kind Code:
A
Abstract:
PURPOSE:To generate a program signal by using an image sensor such as a CCD, and eliminating a movable part. CONSTITUTION:A rotary drum 1 is driven by a pulse motor controlled by a microcomputer of an arithmetic part 7, and an area 30 placed at right angles to a time base of a program sheet 3 is formed imagewise successively on an image sensor 5 through an optical system 4. Each element of the image sensor 5 generates successively a signal of a high level or a low level of a time series corresponding to brightness and darkness of each point of this area 30. This output signal becomes an on-or off-signal corresponding to a high or low level by a level detecting part 6, and stored in a storage part of an operating part 7. As for the program sheet 3, plural program patterns 3a are formed on the sheet so that plural program signals can be generated.
