ABSTRACT:
A tape recorder wherein a control transistor is connected between a power source and a load circuit involving, for example, a motor circuit, mechanism control circuit and amplifier; and automatic shut-off circuit is connected in parallel to the load circuit. The automatic shut-off circuit is arranged to render the control transistor conductive at the time of power supply; and nonconductive when a terminal end of the tape is detected. A single-pole double-throw switch is provided which is only required to have a small current capacity, and has a movable contact connected to a power source, a first stationary contact connected to the voltage-detecting terminal of the automatic shut-off circuit and a second stationary contact connected to the base of the control transistor.
