<p>PURPOSE:To attain the automatic changeover of 3 modes by providing a switching turn piece turned by a mode switching arm and slided by the movement of a head switching plate and a release arm operated selectively by the head switching mechanism and the release mechanism at each position of the mode switching arm. CONSTITUTION:The mode switching arm 1 is supported freely slidably in forward/reverse direction between chassises 10 and 11 and pressed to a pin 12 by a waving shape of spring 1C. when a manual level 1b is selected and moved to the 1st position (1), the 'continuous reproduction repetitive mode' is obtained, and when a pin 2b of the release arm 2 pushes up a circular arc face 4a of a switching trigger 4, the head switching mechanism is inverted. When the level is selected and moved to the 2nd position (2), the 'forward/ reverse recording/reproduction mode' is obtained and even when the pin 2b pushed up the switching trigger 4 before operation stop, the head switching mechanism is not activated. When the 3rd position (3) is selected, the 'one side recording/reproduction mode' is obtained, and when the release arm 2 is moved forward by a pin 3a of a sensor arm 3, a release lever 14 is lifted and the operation is stopped. Thus, the 3 modes are actuated surely.</p> |
