Abstract: Selecting switches are provided near a converter for converting an optical image into an electric signal, thereby enabling the electric signal before or after it was stored to be effectively selected. A plurality of convertors are provided and when an electric signal is not output from one of the convertors, the other convertors can be used. The analog electric signal output from the converter is binarized by a reference level signal before it fluctuates. An electric power consumption when the apparatus is not used is prevented by a power controller arranged near a sensing display.
