The invention relates to a device for recording a take-up reel for ribbons in writing or similar machines, which are pocket-shaped Has container with an Emschubschhtz for the take-up reel.

By the German Offenlegungsschrift 1611469 is a pocket-shaped container with an insertion slot for a cassette-free supply reel known. In order to insert this supply reel into the container, there is an additional holder with a recording dome required. This pocket-shaped container is for holding only

Between the drive pulley 9 and the holding means 11 there is one arranged on the axis 8 Compression spring 12, while a locking washer 8 ″ is attached to the free end of the axle 8 is. The locking washer 8 a serves to stop for the holding means 11.

The hub 13 α of the take-up reel 13, which is known per se and can be inserted into the container 3, has on one side a hole-like recess 13 ft in which a cam 14 is located. On the opposite side, the hub 13 of the take-α 13 having a cylindrical projection 13 provided c, which comes to rest in the slot 4 a of the container. 3 On the side provided with the cam 14, the hub 13 α has a conical collar 13 d which acts on the driver lift when the take-up reel 13 is inserted into the Behalter3 such that the holding means 11 as such deflects towards the compression spring 12. The lift drivers thus get into the recess 13 ft, the Nockeri 14 coming to lie between two of the four lift drivers.

For inserting the take-up reel 13 is inserted, this only in the bag-like container 3, namely so far that the conical shaped collar 13 d on the carriers 11 ft initially comes to rest. Then the carbon ribbon, which is known per se and is not shown in the drawing, is inserted into the take-up reel 1.3, the beginning of the ribbon being pulled through the catching slot 15 and fixed outside the container 3 by the operator. The take-up reel 13 can now

after which it then inevitably refers to the hub 13 "

uer iranspuu of the carbon ribbon takes place in well-known Way by a transport device, which only effects a step-by-step transport wohei -llerdines a relatively large tensile force is exerted on the tape while driving the take-up reel 13 is carried out by a spring belt 10 acting as a slip clutch. The task of Take-up reel 13 consists in winding up the carbon ribbon after it has passed through the transport device, however, only a small amount of torque is required for this.

The device according to the invention serves not only as a recording and drive of the winding reel 13 but it also fulfills the essential functions by inserting and securing the Carbon ribbon on the take-up reel 13 can be done in a simple manner and without replacement Soiling of the operator's hands is possible. In addition, the individual The drive and the resulting sequence of movements causes the take-up reel 13 to spin over prevented.
