Claims

[Scope of utility model registration request]

A sensor body with a built-in light-emitting element and a light-receiving element is placed inside a housing formed by combining a cap with a window hole at the tip and a cylindrical outer case, and the light-emitting and receiving element is connected to the rear of the sensor body. an electrically connected circuit board, and the light receiving element receives reflected light of light emitted from the light emitting element through the window hole to an external medium through the window hole. In the reading device, the sensor body is held between a pair of holders that engage with each other, one end of both holders is engaged with the cap, and the other end of both holders is engaged with the outer case. Features of optical reading device.
