Abstract
A video tape recorder includes a pinch roller mechanism driven by a capstan motor to closely fit to a capstan a tape running from a rotary head. The tape is driven in a selected mode by a reel mechanism driven by a tape loading motor. Different mechanisms and members of the recorder are activated at proper relative timings which are established by a timing control mechanism driven by the capstan motor.
Claims3
A cassette tape reproducing apparatus driving power changeover mechanism comprising:
- a reversable rotary driving source;
- a major power transmission mechanism connected to said driving source;
- and movable in response to said driving source to produce a driving power;
- a cassette loading mechanism responsive to movement of said power transmission mechanism for loading or unloading a cassette to or from a predetermined reproducing position;
- a first subordinate power transmission mechanism for transmitting said driving power from said major power transmission mechanism to said cassette loading mechanism;
- a tape loading mechanism responsive to movement of said power transmission mechanism for partly pulling out the tape from a cassette into a predetermined tape path and retracting said tape therefrom;
- a second subordinate power transmission mechanism for transmitting said driving power from said major power transmission mechanism to said tape loading mechanism;
- and
- a driving power switching mechanism including a sun gear reversibly driven by the driving power from said major power transmission mechanism and a satellite gear engaging said sun gear for movement therearound, means for selectively moving said satellite gear between a first position for engagement with said first subordinate power transmission mechanism and a second position for engagement with said second subordinate power transmission mechanism, wherein at least one of said first and second subordinate power mechanisms is disposed for grazing tangential engagment by said satellite gear so that release of said satellite gear from engagement with said one of said subordinate power mechanisms will allow it to move therepast to engage the other of said subordinate power mechanisms.
