<p>PURPOSE:To improve the reliability of cue review action by providing a lock stroke difference between the 1st and 2nd operation levers, forming a staircase- shaped part at the lock part of the 1st operation lever and engaging the 1st operation lever with the staircase-shaped part of a lock plate when the 2nd operation lever is pressed. CONSTITUTION:A cue review action is performed by pushing in a rapid traverse operation lever 6 and a rewind operation lever 5 after locking a reproduction operation lever 3 by a lock plate 16. A lok stroke difference (a) is secured between a reproduction lock part 16a and the rewind/rapid traverse lock parts 16d/ 16f. This difference (a) is equal to the value obtained by subtracting a release stroke (c) of levers 5 and 6 from a releases stroke (b) of the lever 3. While a staircase-shaped part 16h is formed at the part 16a, and the lever 3 is engaged with either one of stage parts 16c in a cue review mode. Then the plate 16 is held at a position where the locking is impossible for both levers 5 and 6.</p> |
