Abstract

An information input apparatus is constituted of an operation panel that inputs various types of information and an operation panel board that controls the operation panel. The operation panel includes an LCD that is the displaying unit that displays the information input screen for inputting various types of information, and a touch panel that is the input instructing unit that executes an input instruction from an input region (virtual keys) provided on the information input screen. The LCD displays on the virtual keys information different from information previously assigned to the virtual keys on the information input screen.

Claims

1. An information input apparatus, comprising:

a displaying unit that displays an information input screen for inputting various types of information through at least one virtual key, the at least one virtual key being a number, a character, or a symbol; and

an input instructing unit that executes an input instruction from an input region provided on the information input screen,

wherein upon selection of a special settings mode by an operator, the displaying unit automatically displays to the operator who continues to operate the information input apparatus, on the at least one virtual key in the input region on the information input screen, a different number, character, or symbol, without requiring intervention by the operator to display the different number, character, or symbol.

2. The information input apparatus according to claim 1, wherein the displaying unit displays, in the input region on the information input screen, information different from information previously displayed in the input region.

3. The information input apparatus according to claim 1, wherein the displaying unit can display an authentication information input screen for inputting authentication information set in the information input apparatus before displaying a setting information input screen for predetermined functions and displays, in the input region on the authentication information input screen, information different from information previously assigned to the input region.

4. The information input apparatus according to claim 3, including a unit that permits an operation input to the information input apparatus when an input region corresponding to the authentication information is designated on the authentication information input screen, wherein the setting information input screen of the predetermined functions is displayed after the operation input has been permitted.

5. The information input apparatus according to claim 1, wherein the input instructing unit is constructed of a touch panel that can input a coordinate position of an input region on the information input screen.

6. An image forming apparatus including the information input apparatus according to claim 1.
