Such magnetic tape cassettes, which have been on the market for several years, are enjoying excellent results Conception not only with regard to the possibility of being used quickly and conveniently in recording and playback devices to be able to be, but also with regard to the possibility of finished music recordings made by a specialist reproduce, growing in popularity.

An advantageous feature of these cassettes and the corresponding commercially available recording and / or Playback devices consists in the fact that they can play or record in both directions of rotation on different tracks or groups of tracks.

When recording or playback is finished in one direction, the cassette is used to drive the Tape in the opposite direction and for recording or playback on one or more other tracks over the Simply put the entire length of tape in reverse on the recording and playback device.

Thanks to these various devices developed in recent years that allow the removal and insertion the cassette in the recording or playback devices as well as the maintenance of these devices, the manual

handles when reversing the cassette to scan the track or group of tracks on which the one just ended Tape running in the opposite direction, recordings made, are reduced to a minimum. This is particularly true for that described in Belgian patent specification 671 7 ^ 9 Device to, in which the cassette is only to be pushed into guides in order to accommodate them with organs or reproduction of the volume contained in it to engage and to put these organs into action and with the furthermore the cassette by a device for controlling the tape run, as it is for example in the Belgian Patents 672,351 "and 683,865 connected is described will be, if the band is interrupted, especially when it is reached the end of the tape, is tightly released by every block.

However, it is convenient to make these handgrips as simple they may be, to completely suppress and achieve that the device after it is loaded with a cassette the tracks recorded in both directions of travel one after the other before releasing and ejecting the Automatically scans the cassette.

Devices in which recordings are made and played back on a tape in both running directions may have been known for many years, but they are

not for the use of stored in standardized cassettes Tapes suitable and do not allow insertion of the tape by simply sliding the cassette in a single, through Guided tours specific level.

The aim of the invention is to create a device the tracks with recordings after a single movement of the cassette in a single plane determined by guides automatically scans one after the other in both running directions of the tape stored in the cassette and the cassette after scanning the track or tracks in the second direction of tape travel automatically releases and ejects.

A second object of the invention is to provide a device in which, after the cassette has been inserted in the working position the tracks are scanned in a predetermined order of the running directions, the first this direction of movement corresponds to the direction of movement of similar devices, that can only play in one direction.

A third object of the invention is to provide a device which, depending on the position of a user easy-to-use control unit the cassette after scanning the track on the recordings in the first direction of travel recorded or after scanning the tracks,

A fourth object of the invention is to provide a device which sequentially the tracks of a scanned tape stored in a cassette, on which recordings are recorded in both directions, with devices are provided, which allow the user to scan the tracks with recordings in one direction to switch directly to scanning the tracks with recordings in the other running direction.

A fifth object of the invention is to provide a device which, when the cassette is inserted into a position in which the tape is at the end of its run in the first direction, automatically tracks this The tape with the recording in the second running direction is scanned.

A sixth object of the invention is to provide a reliable due to its simplicity and small apparatus whose lower Herstellungqr-ice allows a mass production.

A seventh object of the invention is to provide a device in which a single drive member

An eighth object of the invention is to provide an apparatus in which means are provided for preventing the cassette from being ejected prior to reversing the direction of tape travel.

A ninth object of the invention is to provide an apparatus in which means are provided which show the user the direction of travel of the tape inside the cassette.

For this purpose, this device according to the invention is primarily characterized in that an on the movable plate fixed element during the longitudinal movement this movable plate for inserting the cassette in the working position a slide against the action of elastic Moves elements that serve to drive the tape in a first direction, both on the stationary housing as also brings organs fixed on the movable plate into working position that a lever by the action of a device disengages from the blockage by the element attached to the movable plate to control the belt run and releases the slider for actuation by the resilient elements which move the slider in an opposite direction

Simultaneously with this longitudinal movement of the movable plate 2, the plane of this plate approaches the plane of movement of the cassette, as described in the Belgian patent lur. 671 7 ^ 9 is described; this causes the belt drive mandrels 10-10 and the drive shafts 6-7 of the tape reel spool and the tape unwind reel is inserted into the cassette and the elements fixed on the movable plate for locking the cassette occur in the working position gradually in action.

Furthermore, in this position of the slide from the inclined edge 43 on the bolt 50 attached to the fork 51 no effect, so that the pressure roller 11 presses the tape 4 under the action of the spring 58 against the tape drive mandrel 10 and the drive of the tape through causes this tape drive mandrel in the direction of arrow F. Since the inclined edge 44 has no effect on the end 60 of the lever 61 either, the intermediate roller 13 is pushed elastically between the roller 14 of the belt drive shaft 10 and the roller 12, which drives the axle 6 by friction, under the action of the spring 67; as a result, this axis is driven in the direction of the arrow (Pig · 1) and the tape is rolled up onto the reel &% r cassette into which the axis 6 «la» engages and which is driven by this axis.
