Claims

[Claims for Utility Model Registration] (a) A plunger that operates at different timings when switching from a stop mode to a forward or reverse regeneration mode; (b) a drive gear driven by a motor; (c) (d) a response lever and a trigger lever that respond to the operation of the plunger; (e) a driven gear that has a toothless portion and rotates once in mesh with the drive gear; (d) a response lever and a trigger lever that respond to the operation of the plunger; (f) a switching slide for head switching and traveling reversal provided movably in the left-right direction on the head support substrate; (g) formed on the driven gear; an engaging portion with which the trigger lever engages and disengages; a first cam portion that controls the back and forth movement of the head support substrate; and a second cam portion that selectively moves the switching slide for switching and reversing the head; (h) an actuation lever that is actuated by the responsive lever only when the operation timing of the plunger is long and moves the head switching/travel reversal switching slide from a first position to a second position through a second cam portion of the driven gear; i) A locking means for locking the switching slide for switching the head and reversing the running in the first position or the second position, and when the operation timing of the plunger is long, the head supporting board is stopped by one revolution of the driven gear. At the same time, the switching slide for head switching and traveling reversal is moved from the first position to the second position by the operating lever and locked to set the forward playback mode, and the operation timing of the plunger is adjusted. When the playback is short, one revolution of the driven gear moves the head support board forward from the stop position to the playback position, and locks the head switching/travel reversal switching slide in the first position to set the reverse direction playback mode.
