Title: Password input device
Inventor: TAJIMA TAKASHI
IPC: G06Q20/40
Filed: 1993-05-10
Abstract: PURPOSE:To obtain a device by which the password is scarcely known to a third person by an input operation of the password by switching a numeral array of the numeral display surface to another numeral array, whenever a series of operations are finished and displaying it by a display and input means. CONSTITUTION:When a power source is turned on, a display control means 1, first of all, reads out a first numeral array from a numeral array group 11 to a display numeral array 12 and holds it, and also, this numeral array is given to a display and input means 2 and displayed thereby. When an operator's operation is finished, the display control means 1 selects the next numeral array from the numeral array group 11 for the operator and writes it in the display numeral array 12, and on a display screen of the display and input means 2, a numeral by a second numeral array is displayed. In such a way, as for a numeral display on the display and input means 2, whenever the operator finishes inputting a series of password, the numeral array is replaced successively, and the operator executes a touch switch by this numeral array. Accordingly, even if it is used repeatedly, the specific switch surface is not worn, and there is no fear that the identification number is specified by a third person.
