Title:
METHOD NOT CAUSING SHIFT OF SCANNING LINE OF INPUT/OUTPUT SEPARATING SCANNER
Document Type and Number:
Japanese Patent JPS6048660
Kind Code:
A
Abstract:

PURPOSE: To prevent the shift of scanning line of an input/output separation scanner by using a capacity storing ≥3 scanning lines to a storage device storing a picture signal as to conduct sequentially write and read.

CONSTITUTION: An input cylinder 1 and an output cylinder 2 are turned respectively by driving motors 9, 10 via pulleys 3∼6 and belts 7 and 8. A picture signal of an original A wound on the input cylinder 1 enters an output head 14 via an input head 13, picture signal operating device 19 and the storage device 20, and a copy B is recorded and exposed on a film wound on the output cylinder 2. The storage unit of the device 20 is formed as ≥3 scanning lines, and after both the cylinders are turned in equal speed in synchronizing with power, the storage unit for write is designated based on a pulse from rotary encoders 11, 12 turned coaxially on each cylinder, the write/read is conducted sequentially so as to prevent the scanning line shift of the input/output separating scanner.
