Claims (1)

[Claims for Utility Model Registration] (1) A sensor section having a light emitting element and a light receiving element inside a main casing formed by combining a pair of split pieces, and a spring member for setting the reference position of the sensor section; An electric processing circuit unit electrically connected to both of the above elements is housed, and a tip cap is attached to the tip of the main casing, and the light emitting element is transmitted through the light transmission hole of the tip cap. In the barcode scanner configured such that light from the barcode scanner is emitted to the outside and reflected light is guided to the light receiving element through the light transmission hole, a rib is provided on either the main body casing or the tip cap. The tip cap is fixed to the main body casing by providing a rib-shaped ridge and a locking groove on the other side, and fitting these rib-shaped ridges and the locking groove to each other,
A barcode scanner characterized in that a plate spring is used as the spring member, and the sensor section is brought into elastic contact with the tip cap by the spring force of the plate spring. (2) Inside the main body casing, which is made up of a pair of split pieces, there is a sensor section that has a light emitting element and a light receiving element, a spring member for determining the reference position of this sensor section, and electrical connection to both of the above elements. In addition, a tip cap is attached to the tip of the main casing, and light from the light emitting element is emitted to the outside through a light transmission hole of the tip cap. , in a barcode scanner configured such that the reflected light is guided to the light receiving element through the light transmission hole, the tip cap is fitted to the main body casing in a bayonet mount type, and A barcode scanner characterized in that a plate spring is used as the spring member, and the sensor section is brought into elastic contact with the tip cap by the spring force of the plate spring. (3) In the statement of claim (2), a recess is provided in the inner wall of the tip of the main body casing for press-fitting the protrusion formed on the outer wall of the tip cap, and
A barcode scanner characterized in that a notch is provided on the tip surface of the main body casing for inserting the protrusion and guiding it to the recess when attaching the tip cap.
