Magnetic recording and reproduction apparatus

Abstract

A rotating shaft section of a rotation cam gear supported on the chassis side and transmitting the driving force of a driving motor can be inserted into and removed from a rotating shaft section of a mode detection switch for detecting a mode from the rotating position of the rotating cam gear. A protruding pointed portion and a groove that are fitted to each other to transmit the rotational force of the rotating cam gear are formed in these rotating shaft sections. Output terminals of the mode detection switch are coupled and attached to the circuit section of a circuit substrate, and the rotating shaft section of the mode detection switch is inserted into the rotating shaft section of the rotating cam gear supported on the chassis side to engage the protruding portion with the groove. This constitution enables easy and smooth insertion and fitting of the rotating shaft sections, thereby improving working efficiency.
