摘要:
An electronic board, e.g. a planning board, has a plurality of rows and columns of mechanical coupling means (see fig. 10) and electrically conducting contact areas, respectively, and moreover comprises a plurality of marking elements (70-74, P, S, H, J, E, L, M) adapted to be secured mechanically to the board in a large number of various positions and also adapted to provide electric contact between the electric identification circuits in the marking elements and a plurality of contact areas in the board, so that electric information may be transferred in both directions between the marking elements and the board. This entails that the electronic board enables visualization of data information in the form of a spatial position on the board as well as in the form of individual marking, and conversion of visual information of the latter type into data information signals. The electronic scanning of the board can be established rapidly in that a plurality of contact areas in the board, disposed in the same row and column, respectively, are interconnected to a respective terminal on an X and Y circuit, respectively.

In a preferred embodiment (fig. 6), an identification circuit comprises an input terminal (40), an output terminal (43), a combined counter and comparator circuit (39) with counter input terminals (38), an OR gate circuit (42) and a trigger circuit consisting of an inverter (44) and a multivibrator (41). The said components are connected as appears from Fig. 6, so that rapid identification of an identification code represented by the signals on the counter input terminals (38) can be obtained with just a single input and a single output terminal. The output terminal on the gate circuit (42) may be kept at a high impedance by means of a signal on the input terminal (40) so that a signal may be applied to the output terminal (43), said signal resetting the counter via the trigger circuit (44, 41). After resetting of the counter, the output signal from the gate circuit (42) follows an input signal on the input terminal (40) until reception of a number of input signals corresponding to the identification code on the code terminals (38). The invention also concerns an integrated circuit, in particular for use in connection with a plate having rows and columns of mechanical coupling means for cooperation with a plurality of elements which can be mounted in various positions on the plate. The circuit is characterized in that the housing of the circuit is formed as such a building element and is moreover provided with electric contact areas to provide electric contact with electrically conducting areas in the plate.

A coupling plate with a plurality of electric coupling points comprises, in a preferred embodiment, a pair of plane plates (10, 12), between which there is provided an electrically insulating carrier layer (11), on which a pattern of electrically conducting areas (21-26) is provided. In the preferred embodiment, an electric coupling point is provided for each mechanical coupling stud (15) projecting from the upper side of the top plate (10). The studs (15) are hollow and flush with projections (19) on the lower plate (12) so that punched parts of the electrically conducting areas (20, 22, 24, 26) are just moved up into the hollow coupling studs by means of the projections (19) on the lower plate (12), thus making the conducting areas accessible through cuts (16) in the coupling studs (15). The invention also concerns a method of producing such a plate and a board consisting of a plurality of interconnected plates of said type.
