A pair of elastic strips are provided in order to hold sheet material to be measured in thickness. Each of the elastic strips includes of one or more elastic films. Ends of the elastic strips are supported by support portions, and the other ends of the elastic strips are provided with respective coils, opposed to push each other, and kept in contact with each other. When the sheet material is held between support portions, the inductances of the coils are changed and the thickness of the sheet material is detected as an electric signal representative of the changed inductance.

An image scanning section has an optical system for scanning an original in a two-dimensional manner, and a photoelectric converter for converting an optical image obtained by the optical system into an electrical signal. A binary coding section performs simple binary coding of the electrical signal supplied from the photoelectric converter in such a manner as not to accompany pseudo-gray scale coding, and performs pseudo-gray scale binary coding of the electrical signal supplied from the photoelectric converter in such a manner as to accompany pseudo-gray scale coding. An area designating section designates an area on the original. A scanning mode designating section designates image scanning modes within and outside an area designated by the area designating section and has at least a first scanning mode designating section which does not accompany pseudo-gray scale coding and a second scanning mode designating section which accompanies pseudo-gray scale coding. A controller controls an output or outputs from the binary coding section in accordance with designation by the area and mode designating sections.
