Abstract

Arrangement for keyboards of the optoelectronic type which exhibit a surface area (1) in the form of a prism (16) divided up into fields (17). Each of the fiels is allocated an individual control function. They are intended to be contacted at the respective control function by a surface such as the surface of a finger tip. This causes a deflection of light, which is produced in the field, in relation to the luminous flux in the prism when there is no contact with the surface. The variation in luminous flux is supplied to a light-detecting sensor (19) by means of which an adequate command signal is generated. A control means (20) is so arranged as to produce a signal specific to each field (17) and capable of being selected from the signals from other fields. A single element or a small number of elements is/are provided as the sensor element (19). A signal processing means is also so arranged as to select the signal received from the sensor element in accordance with the specific signal characteristics for each of the fields, and as to transmit an adequate command signal for each field in accordance with said selection.
