Claims

[Scope of utility model registration request]

(1) A cam member having a cam portion and rotated by a control motor, an operating member that engages with the cam portion and moves in response to rotation of the cam member to perform each mode conversion, and the cam member The cam member is made up of a contact piece integrally provided on the bottom surface of the cam member, and a wiring board that faces the bottom surface of the cam member and has a plurality of contacts arranged at rotation locus positions of the contact piece. When the operation member reaches the desired mode conversion position by rotation, the contact piece contacts the contact point on the wiring board at a position corresponding to the rotation position of the cam member, so that the operation member changes according to the mode conversion position. A control mechanism of a tape recorder configured to output an electrical control signal.

(2) The control mechanism for a tape recorder according to claim 1, wherein the output electric control signal stops the rotation of the control motor.
