<p>PURPOSE: To prevent a cassette from being taken out without permission. CONSTITUTION: One end of a takeout lever 13 is borne by a lower surface part of a horizontal carrier and is also supported by a torsion spring 14, so as to take out the cassette from a cassette holder 10 to the outside. Then, a middle part of a locking lever 15 is borne by the lower surface part of the horizontal carrier 12, so as to oscillate the takeout lever 13 in the forward and backward directions to be locked or unlocked. A safety lever 2 is borne to be adjacent to the locking lever 15 by the lower surface of the horizontal carrier 12, and is energized and supported by a coil spring 8, so as to prevent reverse oscillation of the takeout lever 13.</p> |
