Abstract
An image information processing apparatus having a multi-function switch includes an image information reader for reading image information, wherein the reading frequency of the reader can be varied. A first switch is provided for switching between a first reading mode in which the image information printed on a sheet is read by the reader, and a second reading mode in which image information displayed on a screen is read by the reader. A second switch is provided for selecting between a plurality of different reading frequencies in the second reading mode. Control circuitry is provided for controlling the reader to read the image information at a predetermined reading frequency higher than the plurality of reading frequencies in the first mode, and to read the image information at one of the plurality of reading frequencies selected by the second switch in the second reading mode. The control circuitry tests whether a power supply of the apparatus is sufficient when the second switch is actuated in the first reading mode.
