WIPO Patent Application WO/2023/204050
Kind Code:
A1
Abstract:
In order to improve the planarity of the surface of an image sensor for forming a conveyance path for paper sheets, the present invention involves manufacturing an image sensor having a configuration in which a case having accommodated therein a light source part for emitting light to an imaging subject and a light reception part for receiving light from the imaging subject is furnished with a cover that includes a transmission member allowing transmission therethrough of light emitted from the light source part and light received by the light reception part and that includes a frame member which supports the transmission member, the manufacturing comprising: a placement step for placing, on an adhesive tape fixed on a plane, the transmission member and the frame member in a prescribed positional relationship; a first pressure-bonding step for pressing the transmission member onto the adhesive tape and making the same tightly adhere to the adhesive tape; a second pressure-bonding step for pressing the frame member onto the adhesive tape and making the same tightly adhere to the adhesive tape; a bonding step for filling a bonding agent in a gap between the frame member and the transmission member tightly adhered to the adhesive tape; and a releasing step for releasing the adhesive tape from the transmission member, the frame member, and the bonding agent.
