装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a one-dimensional photoelectric conversion device used in a high-speed contact type one-dimensional image sensor such as a facsimile IJ or a copying machine.
(従来例の構成とその問題点)
従来、ファク7ミリ等に用いられる1次元イメージセン

王とl、て用いられて来た。(Structure of Conventional Example and Problems Therewith) Conventionally, a thin film light-receiving element made of Cd5Se has been used in one-dimensional image sensors used in 7mm facsimile and the like.

なる。By using a material with a large change in photocurrent, the light resistance of the photodetector is small (approximately 1.2MΩ at 100A!x illumination), the external switching circuit can be easily configured, and the element electrode It has the advantage of being compact and inexpensive by using matrix-connected multilayer wiring with a large stray capacitance between them. However, in the photoresponse, when CdSSe is used, 5 m, 8ec/l i'ne (however, 1
It is said that the reading speed of 728 elements and 8 elements is the limit, and for this reason, amorphous Se-Te with fast photoresponse is used.
-As, hydrogenated amorphous silicon (hereinafter a-8i:
Write it as H. ) as a light-receiving element has been attempted. Many of these have diode characteristics, and many attempts have been made to accumulate photocurrent in a capacitor and read out the accumulated charge using a switching element, etc.
The results of the above-mentioned number of elements have been obtained. However, although these charge storage type sensors have improved sensitivity, their high resistance circuits allow noise from external switching to enter through stray capacitance, requiring circuit processing to remove noise and switching each element one by one. Since it requires an element, it is difficult to implement. Further, in increasing the speed to 2 m Bec/line or more, problems arise such as a decrease in the integration time and a decrease in the S/N ratio due to an increase in switching noise due to the increase in frequency.

However, COD arrays multiple chips to create a one-dimensional sensor, and there are limits to optical adjustment and compactness of the @ placement, so a close-contact, high-speed sensor using a thin film has been desired.

If the resistance is 0.5Kg including the human resistance of the device, an input voltage of 10mV will be obtained, and the pulse rise at this time will be approximately 12
