The light passing path connecting the paper is arranged so that it is inclined with respect to the vertical line or along the horizontal plane, and the transparent dust-proof glass that covers each of the light emitting elements and the light receiving element is arranged so that the light passing path connecting the paper passing side is inclined with respect to the vertical line or along the horizontal plane. Place it horizontally or tilted so that the paper passing side faces downward,
A dustproof device for an optical sensor, characterized in that paper dust from paper sheets does not adhere to the dustproof glass surface. (2) In the device described in claim (1) of the above utility model registration, each optical element and dustproof glass arranged across the paper path are opaque glass with only the straight portion connecting the light emitting element and the light receiving element open. A dustproof device for an optical sensor, characterized in that it is covered with a cover.
