摘要 PURPOSE: To prevent error pusshing of a key switch or simultaneous pushing of neighboring switches by a method wherein respective resistors and key switches are unitized respectively, the respective units are made free separable by unit, the units are made able to be arranged in an optionable order to the key input device and the resistors inside the respective units are in series connected at the time of arrangement.
CONSTITUTION: A key unit 20A is provided with a key switch 22A with and a resistor 24A in parallel further being provided with the terminals 26A, 28A connected thereto. The key unit 20B to 20F are similarly constituted to the key unit 20A while the resistors 24A to 24F are set at different resistance values respectively. A recessed part (key switch housing part) 32A is formed on the key input device main body 32 so as to enable the key unit 20A to 20F to be arranged in optional positions also to enable resistors inside the respective units to be in series connected. Accordingly, since the key switches can be changed to a convenient arrangement for a user, an error pushing and simultaneous pushing of neighboring other key switches can be prevented.
