摘要： A direction indicator for use in apparatus which includes a rotary member whose direction of rotation is determined by a command signal, the direction indicator providing an indication of the commanded direction just as, or momentarily prior to, the rotary member commences rotation in the commanded direction. A frequency generator generates a signal whose frequency is representative of the actual speed of the rotary member. A speed detector coupled to the frequency generator produces a pulse signal when the speed of the rotary member is less than a predetermined speed. A circuit is responsive to the direction command signal and is actuated by the pulse signal to provide an indicating signal corresponding to the direction of rotation determined by the command signal. The resultant indicating signal corresponds substantially to the actual direction of rotation of the rotary member.

摘要： A video recording and/or reproducing apparatus of the type having a tape guide drum with at least one rotary magnetic head associated therewith, a cassette holding device spaced from the drum and including a holder movable between an elevated position for receiving and discharging a tape cassette and a lowered position for operatively positioning the cassette therein, a tape loading and unloading device effective, in a loading operation, to withdraw tape from the operatively positioned cassette and to wrap the withdrawn tape about the guide drum for the recording or reproducing of video signals thereon by the rotary head and, in an unloading operation, to unwrap the tape from the guide drum and return the tape to the operatively positioned cassette, and a motor energized for operating the apparatus, for example, driving the rotary head and the capstan by which the tape is advanced during recording and reproducing operations; is further provided with a cassette ejecting device which includes a holder displacing mechanism operative, in response to rotation of a drive member, to return the cassette holder to its elevated position for discharging or ejecting the cassette therefrom, a transmission assembly having an operative state for rotating the drive member by the motive force of the above mentioned motor and an inoperative state in which the drive member is disconnected from the motor, and a control for such transmission assembly which permits the establishment of the operative state of the latter only when the tape loading and unloading device is in the condition thereof characteristic of the completion of a tape unloading operation. In a preferred embodiment, the tape loading and unloading device includes a support member moved from a starting position to an operative position during the loading operation and being returned to its starting position at the completion of the unloading operation, and the control for the transmission assembly is responsive to the positioning of such support member to hold driving and driven transmission members disengaged from each other so long as the support member is displaced from its starting position.
