Ribbon cassette that can be changed as required with standardized spools

Modern devices, especially in the wide field of data processing, are very often at the same time as one A writing unit or a "printer" is equipped to show the user the result of his input immediately Include "black on white". In such devices, as in conventional typewriters, ink ribbons are used needed, which expire from a coil core and on wound another, initially empty bobbin will.

In many cases, one has now developed its own cassette for each type of such machine, which is the ribbon and next to it an empty reel to hold the overwritten tape. It has to be shown that it is necessary to select the "correct" one each time a ribbon runs out (consumed) To have the cassette at hand. That is not infrequently very difficult. It is much easier if you know the well-known standardized ribbon reels could alternately be used with such cassettes, so that one could use both the one can use as well as the other.

The present innovation solves the problem here, which consists in an arbitrarily exchangeable ribbon cassette with standardized reels for writing To create machines, which is characterized in that for the tape guide pins present in the machine There are recesses on the cassette.

The attached sketch illustrates the subject the innovation:

The cassette body (1) has two cassette arms (2) in the circular arc-shaped recesses (3) as Recordings for the bolt (6) are provided. There are recesses (4) for the other fastening bolts (7) intended.

There are two spool cores in the cassette body (1) (5) for unwinding or receiving the ribbon (10). These coil cores (5) sit on receiving axes (8), which like the bolts (6, 7) are arranged on the machine side. The ribbon fastener (9) on the spool core can take place in any form. The arrows (11) indicate the direction of the ribbon. With (14) it is closed marked descriptive paper, the type roller (15) moves around its longitudinal axis in the direction of the arrow (16), while the pressure roller or counter-pressure roller (12) moves in the direction of the arrow (13) against the rear of the to be written on.
