<p>PURPOSE:To display all modes of a mechanism capable of reciprocal travel by three display means by installing a display means for displaying normal and reverse rotations and recoding in accordance with the output of a logic circuit. CONSTITUTION:The logic circuit is installed which inputs action instructions such as recording, reproducing and stop and outputs a display output in accordance with said instructions. The action displaying light emitting diode of the mechanism 1 includes a normal rotation display LED 17, a reverse rotation display LED 18 and a recording display LED 19. When any of operation command switches 20-25 is pressed, the pressing is inputted to a microcomputer 13 to execute the pressing logically. (In order to obtain the desired action mode), the reproduction plunger 5 or quick traverse-rewinding plunger 6 of the mechanism 1 is attracted for a specified period, and the desired action mode is obtained. Simultaneously the display output corresponding to the action mode is outputted to the display means 4 by the microcomputer 13, and the action mode of the mechanism 1 is displayed.</p> |
