摘要： An intelligent copier for readily performing image enlargement, reduction, synthesis, and editing. In the intelligent copier, an SIT (Static Induction Transistor) image sensor in which a plurality of SIT image cells are arranged two-dimensionally pixel by pixel in the same substrate is used as an image sensor for picking-up the image of a document. It is not necessary to use an expensive mass storage memory for storing the image information, because the SIT image sensor can perform a nondestructive readout, so that the copier can be made small in size and inexpensive in cost.

摘要： In a chemical analyzing apparatus of a colorimetric type in which a light flux transmitted through a test liquid is made incident upon a light receiving element through an optical filter having a predetermined transmission spectrum range and a measurement signal is obtained by processing a photoelectrically converted signal, a plurality of optical filters having different transmission spectrum ranges and arranged side by side and a solid state image sensor having a plurality of light receiving elements each having a photoelectric converting element and a static induction transistor are arranged one upon the other. An analytical result is obtained by calculating output signals selectively derived from light receiving elements which are arranged behind a particular optical filter having a transmission spectrum range related to a wavelength determined by a test item to be studied. Since use is made of a static induction transistor, it is not necessary to change the optical filters mechanically and is possible to read out the necessary output signals having high S/N selectively in a prompt manner, while the levels of output signals can be monitored.
