Fast-forward, rewind of cassette tape recorders

摘要

The present invention relates to a fast-forwarding and rewinding apparatus for a cassette tape recorder, wherein a transmission gear transfers the rotational force of the drive gear to the first intermediate gear according to the degree of movement of the moving plate when the cam gear rotates using the cam gear. In addition, by transmitting to the second intermediate gear to reduce the power consumption due to the overload protection of the motor and to improve the reliability of the operation by the non-use of the spring.;To this end, the present invention is hinged to be rotated to receive the driving force of the motor to the main base cam cam is formed in the upper surface, the hinge is coupled to the main base is rotated as one end is guided to the cam groove when the cam gear is rotated A moving plate which is connected to a lever and the other end of the pivoting lever and is moved left and right according to the pivoting of the pivoting lever, and is formed on the main base and is formed on the movable plate to guide the left and right movements of the movable plate. Means, a pin-gear hinged to the main base and engaged with the first intermediate gear, and hinge-coupled to the movable plate to transfer the rotational force of the drive gear to the second intermediate gear and the pin gear according to the left and right movements of the movable plate. Transfer gear that transmits selectively, and attached to the main base in the selected mode according to the left and right movement of the moving plate It is configured including the switch to recognize the conversion.
