Abstract
An identification code input board for activating electrical equipment such as an electrical lock includes: a display panel crosswise arranged in the form of M lines X N rows while including a plurality of display sections to display a group of codes of which number is represented by a numeral of m X n, a transparent key switch sheet superimposed on the front surface of the display panel while including a plurality of switches arranged corresponding to the display sections, a display converter for selecting one of plural kinds of display formats, of which number is represented by a numeral of (M-m+1) X (N-n+1), every time the electrical equipment is actuated, and a code reader adapted to output a digitized code signal for distinguishing a selected code, wherein each of m and n is a positive integral number of two or more and each of M X N is a positive integral number larger than that of m and n respectively. In response to a coordinate signal outputted from the transparent key switch sheet superimposed on the front surface of the display panel, a microcomputer is activated to properly actuate an electromagnetic actuator for actuating the electrical equipment.
