8-6-2 Mode Sensor Drive
The mode sensor converts each mode of the mechanism into an electrical signal and transmits it to the microcom-
puter. The FL cam gear is rotated by the loading motor, and the cam slider slides after operation of the cassette
holder.
Then the mode switch also rotates synchronized with the cam slider and outputs a signal corresponding to each
mode. This signal is transmitted to the microcomputer and the microcomputer stops the cam slider at a specified
angle, thus establishing each mode.
The IC601 controls Capstan Motor Drive IC for each mode to make the loading motor rotate in forward or reverse
direction, thereby setting the mechanism at a specified position.
The mode switch develops three outputs A, B and C.
The circuit configuration of the mode sensor drive is shown in Fig. 8-22.
