Abstract
A tape rewinding apparatus for the video cassette comprising a built-in tape end detecting member which will detect the tape end and generate an electric signal; an ejecting solenoid actuated by said electric signal to start the cassette eject operation; and an electronic control circuit for automatically cutting the power supply.
Claims2
An electrically operated tape rewinding apparatus for a video cassette including a cassette compartment lid member, the apparatus comprising a tape end detecting member adapted to send an electric signal as the end of a tape appears, and means for ejecting the cassette upon receipt of the electric signal;
- characterized in that
- said ejecting means comprises a catch which locks the cassette compartment lid at closed position, and a solenoid for releasing the catch to open the lid upon receipt of the electrical signal;
- and wherein
- said ejecting means further comprises a controlling member driven by said solenoid, and a crank arm urging said lid to an open position.
A tape rewinding apparatus for a video cassette having a cassette compartment lid, the apparatus comprising a tape-end detecting member which sends an electric signal as the end of a tape appears, and means for ejecting the cassette on receipt of the electric signal;
- characterized in that
- said ejecting means comprises a catch for locking the cassette compartment lid at closed position, and a solenoid for releasing said catch to open the lid upon receipt of said electric signal;
- and wherein
- said tape end detecting member is a centrifuge-type actuator, said apparatus further comprising a motor driving a winding spindle by means of a transmission belt, said actuator being rotatably driven, and, said apparatus further comprising a switch in circuit with said solenoid;
- and said centrifuge-type actuator is driven to rotate by the transmission belt, whereby the centrifuge-type actuator can activate or inactivate said switch through the the centrifugal force acting on said actuator.
