The invention relates to a loading mechanism in a tape deck of a magnetic-tape-cassette apparatus, for moving a magnetic-tape cassette from an eject position of the loading mechanism into a play position of the loading mechanism. The mechanism comprises a cassette holder for holding the magnetic-tape cassette and a first lift plate, by means of which the cassette holder is movable between an intermediate position of the loading mechanism and the play position of the loading mechanism substantially in a vertical loading direction. The first lift plate and the cassette holder are movable from the eject position into the intermediate position in a horizontal loading direction, and a lift element is arranged on a frame so as to be rotatable and so as to be movable in the horizontal loading direction. The cassette holder, the lift element and the first lift plate are movable from the intermediate position into the eject position and vice versa in the horizontal loading direction. When the first lift plate is moved in the horizontal loading direction it exerts a force on the cassette holder and the lift element in such a manner that the cassette holder is moved substantially in the vertical loading direction, during which movement the lift element performs a rotary movement.
摘要:
A magnetic tape cassette apparatus which has a magnetic head switchable between two groups of channels, respectively for forward and reverse play. Music searching, which detects pauses of at least a minimum duration in a group of recording tracks, is operable during fast forward or fast reverse along the track previously selected. In the fast winding mode the switching member for channel group selection is held in the position it occupied prior to actuation of fast winding.

A flywheel in a magnetic tape apparatus includes preferably identical, flat discs (3a, 3b) which are joined to one another and each have a bevelled portion (11a, 11b) at their circumferences (9a, 9b). The bevelled portions (11a, 11b) define a circumferential groove (17) for a belt (19) and the two discs (3a, 3b) are joined to one another in mirror-inverted relationship.

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.
