发明名称 DOUBLE OPERATION PREVENTING DEVICE
摘要 <p>PURPOSE:To prevent double operations surely by providing a means of absorbing the more than fixed load applied to the fast feed operation button side when a recording operation button is depressed in a fast feed state, to the recording operation side. CONSTITUTION:The absorbing lever 5 provided to a recording operation button 2 is energized leftward by a dragonfly spring 6 and likewise a stopper 7 blocks more than fixed rotation of the lever 5. A stopper 12 which is provided to a mechanical chassis 8 blocking more than fixed sliding of the lever 2 is in the position of blocking the sliding of the lever 2 by engaging to the lever 5 only when it is in the position turned rightward in the position before the lever 2 changes over the recording switch 3. When the recording operation button 1 is pushed while a fast feed operation button 11 is held depressed, the lever 9 is slided in the direction of the button 11 by the lever 5 but is blocked by abutting against the side face of the button 11. When the button 1 is pushed further, the lever 5 slides and engages to the stopper 12 in the fixed position where the switch 3 does not change, thereby blocking the sliding of the lever 2. Hence, the double operations are surely prevented.</p>
