Abstract

PURPOSE: To make it possible that operation modes are switched by one or two switches, by determining the shift direction of a shift register, which shifts operation modes successively each time a clock pulse is inputted, by a single-pole double throw switch.
CONSTITUTION: By turning on a power source switch, stopping D-FF44 is set to light display equipment 28. Next, when switch 11 is closed, the output of OR gate OR4 becomes high-level, and oscillator circuit 19 is operated to generate a single pulse at a prescribed-time period while switch 11 is closed, and this pulse is applied to shift registers 41W44. Q output signals of DFFs41W43 and 45 for recording, fast- feeding, reproducing and rewind are inverted to a high level successively each time this pulse is applied, and corresponding display equipments 25W27 and 29 are lit successively. When switch 11 is opened after confirming that the display equipment corresponding to a desired operation mode is lit, a high-level signal is applied to output part 3 through inverter I to open a corresponding gate of AND gates A9W A12, thus performing a prescribed operation.
