Description

Detailed Description of the Invention

The present invention relates to a recording and / or reproducing apparatus as defined in the preamble of claim 1 of the claims.

Such a recording and / or reproducing device is known, for example, from the patent document WO98 / 44499A1. In this known device, the pull-out tape is fixedly connected at its first end to the take-up reel in the area of the take-up reel hub.

In such types of recording and / or reproducing devices, it is important that the length of the pull-out tape between the take-up reel and the pull-out element matches the predetermined nominal value as accurately as possible. This is because once the draw-out tape is wound onto the reel hub of the take-up reel and the draw-out element engages in the recess of the take-up reel reel, it is guaranteed that the draw-out element is located in the nominal position as accurately as possible. Because.
This is important. Otherwise, the improperly positioned and improperly arranged extraction elements adversely affect the proper winding of the record carrier, which is in the form of a tape, drawn from the cassette onto the take-up reel. Because it affects.

In the known device described in patent document WO 98 / 44499A1, the exact length required for the draw-out tape is obtained by precisely manufacturing the draw-out tape and mounting it exactly on the take-up reel. However, this requires relatively high manufacturing and mounting precision and a corresponding cost. Furthermore, there is no means to correct any possible changes in the length of the draw-out tape between the take-up reel and the draw-out element. Such changes, which may overly incorrectly position the pull-out element with respect to the take-up reel, may be due to temperature and moisture effects depending on the material used for the pull-out tape.

It is an object of the present invention to eliminate the above mentioned problems, or reduce them at least to a practically insignificant level, and to provide an improved recording and / or reproducing apparatus.

According to the invention, in order to achieve the above object, the characteristic configuration defined in the characterizing part of claim 1 is provided in the recording and / or reproducing apparatus defined in the preamble of claim 1.

If necessary, a simple adjustment of the length of the pull-out tape between the take-up reel and the pull-out element with the aid of the length adjusting means is achieved in a simple manner.
Such adjustment of the length of the pull-out tape may first be carried out during the manufacture of the recording and / or reproducing device of the invention. However, this length adjustment may be carried out later in order to compensate for length changes caused, for example, by aging effects, temperature influences or moisture influences.

In the recording and / or reproducing apparatus of the present invention, the length adjusting means can be configured in various ways. For example, a rotatably attached anchoring element is provided inside the reel hub of the take-up reel and the second end of the pulling tape is fixedly connected to said anchoring element to provide more or less pulling tape. Is wrapped around the anchoring element to allow length adjustment. However, it has proved to be very advantageous when the recording and / or reproducing apparatus according to the present invention is further provided with the characteristic structure defined in claim 2. This is advantageous because it makes it possible to achieve a very fine adjustment of the draw-out tape.

In the recording and / or reproducing apparatus of the present invention having such an adjustable length adjusting element,
Furthermore, it has proved to be very advantageous with the features defined in claim 3. As a result of doing so, the length of the pull-out tape is adjusted particularly easily and evenly.

The recording and / or reproducing device according to the invention with an adjustable length-adjusting element has proved to be very advantageous when it is further equipped with the features defined in claim 4.
It allows the length adjustment element to be firmly fixed in the position it occupies after the length adjustment process.
