<p>PURPOSE:To prevent the erroneous erasure of a B-face channel and to enable a dubbing action between the channels of the faces A by providing the 1st and 2nd detecting members detecting the presence or absence of an erroneous erasure preventing lag and operating forcibly the 2nd detecting member in the state where the presence of a corresponding lag is detected when an operation is switched in a normal dubbing mode. CONSTITUTION:The 1st and 2nd detecting members 28 and 29 are turned and energized counterclockwise. When one detecting piece 29a detects the absence of the lag 11 and is inserted into a recessed part 12, its inhibiting piece 29b inhibits the operation and shift of a recording lever 22. A control piece 29d is formed integrally on the 2nd detecting member 29, and is faced downward a step part 16a formed on the operational lever 16 of a selection switch 13. When the operational lever 16 is pressed and operated to set in the normal dubbing mode of the selection switch 13, the 2nd detecting member 29 is forcibly turned at the position where the presence of the lag 11 is detected through the step part 16a and the control piece 29d.</p> |
