<p>PURPOSE:To miniaturize a device by providing a miniature cam mechanism part in respect to the magnetic recording/reproducing device for recording/ reproducing a signal while running a magnetic tape in the manner of winding it around a cylinder furnished with a rotary magnetic head. CONSTITUTION:Two cam followers 23, 24 provided in the device are arranged on a driving plate 21 which is mounted so as movable to left and right, and cam gears 27, 28 provided with cam grooves 29, 30 transmitting the driving force to these cam followers 23, 24 are arranged at different rotation center positions. Thus, the driving plate 21 is driven by large stroke while combining the cam gears 27, 28 having small diameters.</p> |
