Abstract
A magnetic-tape-cassette apparatus includes a deck, a reel-drive mechanism forming part of the deck, and a head support which carries a magnetic head and is movable between a play position, in which the head can be applied to a magnetic tape accommodated in a magnetic-tape cassette, and an eject position. The head support is spring-loaded towards the eject position and is movable towards the play position by a traction mechanism. A drive wheel of the traction mechanism is rotatable by a drive device of the deck. The traction mechanism further includes a segmental toothed wheel which has a toothless portion and which can be driven by the drive wheel of the reel-drive mechanism, the toothless portion facing the drive wheel in the play and the eject position of the head support through the action of a latching device. The segmental toothed wheel further includes a wholly toothed segment which meshes with a traction wheel having a pin which can act upon the head support in such a manner that it either presses said support into the play position or blocks the rotation of the traction wheel in a position in which the toothless portion faces the drive wheel and is consequently not in mesh with said drive wheel.
