Abstract
A document reading apparatus includes a sensor configured to receive light from a document, an imaging lens configured to form an image of light from the document on the sensor, a first holding member to which the imaging lens is fixed, and a second holding member to which the sensor is fixed, wherein the first holding member and the second holding member are fixed using an adhesive and solder.
Claims10
A document reading apparatus comprising:
- an optical unit comprising:
- a sensor configured to receive light from a document;
- an imaging lens configured to form an image of light from the document on the sensor;
- a first holding member to which the imaging lens is fixed;
- a sensor substrate on which the sensor is mounted;
- a second holding member to which the sensor substrate is fixed;
- and
- an optical unit frame to which the first holding member is fixed,
- wherein the first holding member and the second holding member are made of metal, and
- wherein the first holding member and the second holding member are fixed using an adhesive and solder.
A method for assembling an image reading apparatus, the image reading apparatus including an imaging lens configured to form an image of light from a document, a solid-state image sensor configured to receive light from the document via the imaging lens, a first holding member to which the imaging lens is fixed, a sensor substrate on which the solid-state image sensor is mounted, a second holding member to which the sensor substrate is fixed, and an optical unit frame to which the first holding member is fixed, wherein the first holding member and the second member are fixed using an adhesive and solder, the method comprising:
- fixing the first holding member and the second holding member to each other using the adhesive;
- and
- fixing, after the adhesive has hardened, the first holding member and the second holding member to each other using the solder.
