ABSTRACT:
A cassette loading and unloading device has a guiding element for positioning a cassette either in an ejected position or in an inserted position, a spring for urging the guiding element towards the ejected position and a locking element for locking the guiding element in the inserted position. The locking element is held in a locked position by the energization of an electromagnet which is effected during the closure of a switch. The release of the guiding element from the locking element and the movement of the guiding element to the ejected position are established when the switch is turned off to de-energize the electromagnet.
