Input apparatus for computer

Abstract

An input apparatus for computers is interposed between a keyboard and the computer. This apparatus comprises: an area designating device on which a desired visible information sheet having predetermined visible information can be disposed and which outputs a designation area signal indicative of the designated area of the visible information; a receiver to receive registration data comprising the area of the visible information and the key code of one or a series of plurality of keys corresponding to this area, the registration data being sent from an external system; a registering memory to store the registration data received by the receiver; a data fetching circuit to take out the corresponding key code from the registering memory by reference to the registration data in response to the designation area signal which is given from the area designating device; and a transmitter to transmit the fetched key code to the computer. With this apparatus, by previously making a desired visible information sheet and the registration data of the sheet, the registration data can be easily registered in the input apparatus, so that the operator can easily operate the input apparatus and input the key code to the computer by designating the area on the sheet.
