Single-key input system

摘要

A single key input system for an apparatus such as a facsimile machine having a plurality of operations. A set sequence of functions each of which would normally require the entering of a separate key may be executed by a single key. A coordinate input unit has operator designatable areas. The set sequence of operations is programmed into the apparatus and executed by indicating a designated area. Therefore, the operator can both create a set sequence of functions which are executable through a single key and can designate the location of that key.
