Claims

[Scope of utility model registration request]

a mode switching operation section that switches and operates the tape recorder mechanism section to a predetermined mode; a signal generator that generates a pulse signal in conjunction with the mode switching operation section; a reference pulse generator that generates a reference pulse when the signal generator moves to the reference pulse generator; and a count number and mode selection input section of a counter that counts the number of pulses output from the signal generator with reference to the reference pulse from the reference pulse generator. and a control circuit that gives a command to the mode switching operation section to operate the tape recorder mechanism section to switch to a mode corresponding to the mode signal by comparing and calculating the mode signal from the tape recorder. Mode switching device for tape recorders.
