<p>PURPOSE:To simplify an entire device structure and to attain a compact and light-weight VTR together with reduction of cost by providing a motive power switch mechanism which can transmit alternately the driving force of a single motor so as to perform both zooming and loading operations of a video lens with a single motor. CONSTITUTION:A photographing/recording mode, a bar 45 is driven toward an arrow (a) by an actuator 44 and a swing arm gear 43 is revolved toward an arrow (b). Thus the driving force of a motor 40 is transmitted to a zoom transmission gear 50 from a zoom transmission gear 48 to drive a video lens zoom mechanism. When a recorder mode switch signal is inputted in a photographing mode, the bar 45 is driven toward an arrow (c) and the gear 43 is revolved toward an arrow (d). Thus the driving force of the motor 40 is transmitted to a loading gear 47 from a loading gear 46 in order to drive a video recorder loading mechanism. In such a way, the driving force is properly switched in each mode. Then both video lens zoom and video recorder loading mechanisms can be driven with a single motor.</p> |
