Abstract: In the case of the conductor film (4) resting on a base the contact conductor tracks are arranged on a tab attachment (5) so as to run parallel to each other. Furthermore, in the base an open shaft (6) which runs obliquely downward is provided, on whose obliquely sloping bottom surface the tab attachment (5) with the contact conductor tracks which are free at the top comes to rest. For making contact, a plug socket, together with its contact spring element (8) passed outward and facing the bottom surface of the shaft (6), is inserted into the shaft (6) in the direction of the free tab end and is fastened in the end position in a locking manner.

Abstract: An adjustable keyboard support device is provided having a tubular bearing element (1), secured to a housing bottom (5) of a keyboard. A generally L-shaped stand (2) is provided with two bearing pins (3, 4) which fit respectively into tube ends of the bearing element. The stand includes two U-brackets (6, 7) placed perpendicularly to one another. The two jointly pivotable U-brackets (6, 7) of different lengths. A locking element (8) extends from one of the U-brackets, engaging in the bearing element (1) for fixing the position in one of the two inclination angle settings.
