A gear driving mechanism for driving a power cam, etc. for a tape recorder, in which a power cam driving working elements by its normal rotation is driven by a motor and the rotation direction of the motor is reversed for the purpose of loading, eject, etc. The mechanism is so constructed that a pivoting gear pivoting depending on the rotation direction of the motor is disposed at the motor side; a normal and a reverse rotation gear engaging with each other is disposed at the gear side; the pivoting gear at the motor side is engaged with one of the normal and the reverse rotation gear when the motor rotates in the normal direction, and with the other when it is pivoted by the reverse of the rotation of the motor.

A loading and ejection mechanism in a tape player includes a link mechanism which transmits a motor power to a tape pack transport mechanism to drive same for loading or ejection of a tape cassette. The link mechanism includes at least one resilient connection member which normally maintains a power transmitting relationship of the link mechanism and a connection releasable arrangement which releases the power transmitting relationship of the link mechanism against the energy of the resilient connection member when an excessive load is applied to and locks the mechanism.

Releasable connection arrangement of a loading and/or ejection mechanism

A loading and ejection mechanism includes an inversion gear rotated by a motor in the opposite directions, an eject plate having a rack engageable with the inversion gear, and a mechanism to bring the rack into engagement with the inversion gear, so that the eject plate is moved back and forth by rotation of the inversion gear during loading and ejection so as to move a pack guide up and down and move an eject arm back and forth.

Loading and ejection mechanism for tape player

An optical data communication system using an optical star repeater which converts an optical signal transmitted from a terminal unit into an electric signal, amplifies the electric signal, reconverts the amplified electric signal into an optical signal, and then distributes the optical signal to respective terminal units inclusive of the terminal unit which transmitted the optical signal. The star repeater includes collision detector means for detecting a collision condition in communication, and output control means for interrupting the distribution of the optical signal to the terminal units. The output control means is controlled by an output of collision detector means so that, in response to a collision, it is caused to cut off the signal distribution to the terminal units. Simultaneously with the cut-off of the signal distribution, a collision signal indicating the occurrence of a collision is distributed to the respective terminal units, whereby the terminal units can accurately and immediately detect the collision condition.
