Zusammenfassung:PROBLEM TO BE SOLVED: To perform a high speed call to a stored camera angle position by providing a document presenting device with a pan/tilt mechanism to perform pan/tilt operation of a camera for a table surface and a call function part to move the camera to the stored camera angle position at the highest speed. SOLUTION: The document presenting device is provided with a preset function by which the camera part is moved faster than conventional moving speed and reaches a preset and stored position at the highest speed. When information on a rotation angle of a preset and stored pan potentiometer 52 is executed, when preset switches 92a or 92b is depressed, data in an EEPROM 116 are read, after that, output of a pulse modulation signal is made to be maximum and outputted to a pan motor driving circuit 114 by a main CPU 112 in the device. The pulse modulation signal is converted into DC voltage and a pan DC motor 48 is driven at the highest speed by the pan motor driving circuit 114.
