"Provision of booking machines, typing machines or the like«, for processing account cards or the like, "

The subject of the present innovation is a device for booking, typing machines or the like. for editing of account cards, magnetic account cards or the like 4

In the field of data processing, more and more people have switched to magnetic account cards !! to be used as a data carrier. The magnetic account card consists of a cardboard material with a weight per unit area of approx. 160 g / m². The magnetic account card has a glued-on magnetic tape or printed magnetic ink on the side. By means of a read-write head and an erase head may be any data content -On the tracks - are d§s magnetic tape od stored, deleted - usually several juxtaposed.

The problems with magnetic writing and reading of the magnetic stripe can be seen in the fact that the Always position the read / write head in relation to the magnetic stripe the same, i.e. it must be reproducible. A lateral offset or tilting of the account card and thus the Magnetic stripe inevitably has a wrong record As a consequence,

In the case of those used in the aforementioned area, As a state-of-the-art push-fit device, the required guidance of the gastro-account card became necessary solved with the help of a sprocket od, friction gear, in such a way that the sprocket the sprockets in one on both sides

engage the perforation arranged on the account card. In addition, the account card is guided laterally through metal sheets in card pockets. The disadvantage of this type of card guide that with \ ^r different widths debit cards drafting the map pockets and with them the Staohelräder according to the account card format must be moved sideways.

The basic structure of a friction wheel transport is in like with the sprocket drive, only so-called friction wheels occur here instead of the sprocket wheels, which means the side perforations in the account card can be omitted. But also with a friction wheel transport for account cards the above-described disadvantage arises with regard to the lateral displacement.

Another disadvantage is that the account card can only be transported back and forth it is desired that the account card only in one direction; from head to toe, is processed magnetically, i.e. in the order "read - erase and write on the magnetic strip", you must inevitably use the account card Either move an empty step back during forward or return transport and consequently conditional Loss of time. Furthermore is from the drive motor

both a start stop and a reversing function drove required. In this context it was already proposed that the account card be clamped on a rotating drum in order to avoid empty steps. It has been shown, however, that the management of the account cards is very difficult.

The inventor, in recognition of the aforementioned shortcomings, set himself the task of disclosing a device in which the previously known shortcomings related to the management of magnetic account cards are avoided a circular path and for guidance in the same on the circumference of the casing in the form of a lattice-like drum, which is formed from longitudinal bars distributed around the circumference, which are held by spaced-apart hangings for guiding the account card, with the guide rings being distributed on both sides of the circumference of the casing Veichenfltigel are arranged laterally offset from each other and that one of the end sides of the drum, a rigid ring suwie board in the region of the annular circuit board arranged distributed drive and counter pressure rollers aufwei * t.Zur pivoting of the diverter vane are magnets or the like "means provided.

The drive rollers are arranged on the outside and the counter-rollers on the inside, with the axes of the drive rollers running horizontally and those of the counter-rollers in one
¥ angles of about 10 ° to the same. The drive

rollers are driven by an electric motor with one direction of rotation.

Inside the drum-like device in the area of the circular path, the reading- Write head and the erase head arranged.

Furthermore, the object of the innovation is characterized in that the drive rollers are made of an abrasion-resistant material » rial, such as rubber, plastic or the like «are made.

Finally, it should be mentioned that the one with the drive rollers cooperating counter rollers are resiliently mounted and made of metal.

The following description serves to explain the according to the innovation, of which an exemplary embodiment is shown in the drawing; show it:

According to the innovation, the magnetic account card is guided in a circular path by the pivotable WeiohenflUgel 1 and rigid guide rings 2, which are laterally offset from one another. By pivoting a switch with the help of a magnet or the like. the magnetic account card can be let into the circle at 1 'or let out at I ¹¹ ; will. The position of the switch wing 1 for letting the account card in or out of the circular path is shown in Fig. shown in dashed lines ^{at L 1} and I ^11. A switch includes several, spaced apart pivotable switch wings 1. Since the entire outer magnetic account card guide is formed by the switch wings 1, the magnetic account cards can leave the circuit at different, predeterminable points after the magnetic processing. The account card can optionally be circulated once or several times. After leaving, it is easy to sort the account card and then transport it to the appropriate storage compartments. A new account card is withdrawn as soon as the base of the previous account card has passed a light barrier and this passes a signal on to the program. Since the light barrier is a well-known device, it will not be considered in more detail.

The transport and management of the magnetic account card

takes place after the collection by means of the drive rollers and the associated, resiliently mounted Gegenrollan k. The counter rollers k form an angle of approx. _{10 to the axes of the drive rollers 3 and thus generate a lateral guiding force K g} on the account card such that the account card is always guided on a rigid side plate 5 regardless of its width. The read / write head 6 and the erase head 7 are arranged between two counter rollers k within the troramel-like devices in the region of the circular path. Because the read / write head 6 and the erase head 7 are in the inner circle, the result is that the account card is wrapped around the heads 6 and 7 with a natural angle and consequently a high amplitude ratio is given when reading and writing

The advantage of the subject of the innovation over the known is to be seen in the fact that through the leadership the account cards on a circle and through the appropriate »interpretation of the diameter of the circle, the ones mentioned at the beginning Lost time can be avoided. Another advantage is that only one Direction of rotation of the continuously rotating drive motor is required. It is also to be regarded as an advantage that after the innovation account cards different

Opposite #en previously used Magnet-Accounts-VerarbeituBgseinbfciNNft there is another advantage that the account card is very is transported precisely and without lateral offset or tilting over the read / write head and erase head. strip of information written or read by the same. The information density (bit density) can according to the innovation are higher than is the case with the known processing devices.

Finally, it should be mentioned as an advantage that, since no drum that is closed on all sides in the sense of the conventional is used, no great weight— mass must be moved «Also with the subject of the innovation there are no account card clamps, like this one up to now Case is required.
