することにある。[Problems to be Solved by the Invention] In the prior art, insufficient consideration has been given to sensor diagnosis, and no effort has been made to reduce the amount of light emitted during the check. Furthermore, even if this is taken into consideration, the light emission level of each sensor is reduced by a certain amount. In other words, since cleaning was performed at the same level for both heavily soiled and lightly soiled sensors, it was not possible to accurately determine the cleaning cycle. An object of the present invention is to correctly determine the cleaning cycle depending on the dirt on the sensor.

A plurality of light emitting elements driven by the light emitting circuit, a plurality of light receiving elements corresponding to the light emitting elements, and an output of the light receiving element are
It consists of a light-receiving circuit that converts light into a value, and when checking the margin for reducing the amount of light emitted from a normal level, this is achieved by diagnosing the sensor by setting each light emitting element to a different light emitting level.

路６よりアラームを発生する。In sensor A, during normal use, the light emission amount variable circuit 1
, the light emitting circuit 2 causes the light emitting element 3 to emit light at the light emitting level (10). The light receiving circuit 5 outputs a binary level indicating that there is a paper sheet if the optical axis is blocked by a paper sheet, and that there is no paper sheet if the optical axis is not blocked. Next, during sensor diagnosis, the light emitting element 3 is caused to emit light at the light emission level (9). At that time, if the light receiving circuit 5 detects that there is a paper sheet even though there is no paper sheet, it is determined that the detection is erroneous due to adhesion of dust, etc., and an alarm is generated from the maintenance information and output circuit 6.

よる障害を減らすことができる。According to this embodiment, the margin check level can be adjusted by varying the light emission level during sensor diagnosis for each sensor used in a different usage environment, so that each sensor can be cleaned and replaced at an optimal time. Moreover, this makes it possible to reduce failures caused by false detection by the sensor.
