Record repetitve playback type universal position control system

Claim 1

A record- repetitive-playback position control system, comprising a. at least one continuous servomechanism control shaft (28); b. an on-off servomechanism control shaft (35); c. information processing means, including 1. memory means for storing digital data; 2. a read-write unit (2); 3. a decoder (3); 4. an arithmetic unit (4); 5. an input-output information register (5); 6. an input-output control unit 6; and 7. means connecting between said memory and said input-output control unit said read-write unit in series succession said decoder, said arithmetic unit and said input-output register; d. control means for controlling the operation of said information processing means, including 1. an external interruption control unit (9); 2. a read-write control unit (8); 3. a read-out selection counter unit (7); and 4. means connecting between said external interruption control unit and said information read-write unit in series succession said read-write control unit and said read-out selection counter; e. means for storing in said memory in synchronism with the operation of said control shafts information corresponding with the instantaneous position of said control shafts, including 1. means including a first manually operable positioning means (24) for selectively positioning said continuous control shaft in a number of selected positions; 2. position detector means (29) responsive to the instantaneous position of said continuous control shaft connected with said input-output control unit for recording in said memory detected position signals (B) corresponding with said continuous control shaft position; 3. means including a second manually operable positioning means (32) fr operating said on-off control shaft to one of its on and off conditions; 4. means including an on-off information register (33) connected with said input-output control unit for recording in said memory on-off signals (C) corresponding with the instantaneous condition of said on-off control shaft; and 5. means including a command data information encoding unit (40) connected with said input-output control unit for recording in said memory in synchronism with said detected position signals and said on-off signals a command signal (D); 6. switch means (23, 31) operable from a store condition to a playback condition for disconnecting the positioning means of said continuous control shaft from first and second manually operable positioning means, respectively, and for connecting said shaft positioning means with said input-output control unit; and 7. means (10) operable when said switch means is in the playback condition for transmitting to the positioning means of said servomechanism control shafts selected detected position and on-off signals stored in said store means, whereby repetitive reproduction may be obtained at a speed having a predetermined ratio to the information storage speed.
