Abstract
A picture reading apparatus is disclosed which comprises a camera which converts a picture to be read to an electric signal, a supporting member for supporting the camera movably, and a voice input unit. A control device serves to minimize the output from the voice input unit during movement of the supporting member. Thus while a mechanism for moving the camera is in operation, the output from the voice input unit is minimized to suppress the output of operational noise.
