モード切換機構。 A circular cam for mode detection that has a cam plate for driving the head base, a cam plate for driving the tape reel, and a plurality of cams for operating switches formed at predetermined positions on the peripheral edge that rotates coaxially and integrally with these cam plates. A detection switch that is turned on and off by a cam that operates the switch by rotating the circular cam plate for mode detection, and a detection switch that turns on and off the power supply and changes the polarity of the power supply by turning the detection switch on and off. A mode switching mechanism for a tape recorder, comprising: a motor for rotating each of the cam plates.
