Abstract

PURPOSE: To simplify the structure without a through hole, by superposing each other two printed board on which a parallel electric conductor group is disposed, so that each parallel electric conductor group crosses at right angles.
CONSTITUTION: The first printed board 9 having the first electric conductor group 10 whose conductors are disposed in parallel respectively on the surface, the second printed board having the second electric conductor group 12 which is disposed on the surface in the direction crossing at right angles with the electric conductor group 10, a spacer 14, a conductive elastic body 16, and a character board 17 are superposed each other. As for the printed board 11 and the spacer 14, the windows 13, 15 are made around each crossing point of the electric conductor groups 10 and 12, respectively. When the position of the window 15 of the spacer 14 is depressed from on the character board 17, the contacts 18 and 19 are short-circuited by the conductive elastic body. When an electric conductor containing the contacts 18, 19 which are short-circuited is discriminated from in the electric conductor groups 10, 12 by a detection circuit, the information given to the crossing point of the depressed position can be input.
