or recordable data is limited to a given coding system. For example, a conventional data punch can only provide data punched strips which have a combination of perforations in accordance with a predetermined coding system. The combination of the perforations and therefore the specified coding system cannot be changed in any way in such conventional machines. ¹ Therefore, it has hitherto been necessary to additionally provide a code converter in order to be able to switch from one given coding system to another. In terms of operability and economy, this "additional effort is of course extremely disadvantageous. Another disadvantage of the conventional machines is that a number of code rods that differ from one another in their shape are required, which makes the production of the machine extremely inefficient.

A key mechanism has already been proposed which contains electrical equipment and in which one can switch from one coding system to another. here However, it is disadvantageous that the stability or accuracy of the Operation is affected and also the manufacturing costs are high.

It is an important object of the invention to provide a key mechanism while avoiding the disadvantages of conventional designs to create for the control of a data input device, with which this is variably controllable, so that data can be recorded according to any desired code on the recording medium. The device

should in particular by a simple manual adjustment process be convertible and conveniently made from as few as possible. adjustable and mountable parts exist, so that series production is possible at reduced costs. The invention is also directed to a data punch, with the input data for computer-carrying punched tape according to any Codes3> -stem can be generated, so that there is no need to used an additional code converter together with d'em Computer to be provided or built into it.

In a key mechanism of the type specified at the outset, the invention provides that a number of first Elements are each arranged on a key-operated organ that a number of second elements with the data input device are connected and that at least one of the elements of the two groups is manually in an active position and can be moved into an inactive position with respect to an element of the other group.

"With such a key mechanism, it is possible to control a data input device in the manner that between first and second elements mechanical active or Attack positions are established. A change the control can easily be effected by the active or Attack position according to the code system of a used Data reading device or machine changed. When a key is pressed, data can then be transferred mechanically entered with the selected code. ·
