Abstract
This invention relates to a mode changing system for a cassette tape recorder in which operating members such as a head base plate and a pinch roller are selectively moved to one of various modes such as stopping, fast forwarding, rewinding, pausing, cueing and playing. This system comprises control means to control the movable components so as to move them to a position corresponding to a selected one of the modes. The control means is actuated by a control electric motor. The system further comprises a mode selective switch group to select one of the modes, a reference signal generating circuit to generate a reference signal corresponding to the selected one of the modes in accordance with the selection of the modes by means of the mode selective switch group, a variable signal generating circuit to generate a variable signal which continuously varies with the rotation of the control electric motor and an operational circuit to receive both of the reference and variable signals so as to rotate the control electric motor for moving the movable components toward the position corresponding to the selected mode.
