Abstract
An image reading device and a method for manufacturing the same are provided, where the image reading device is capable of being assembled more efficiently. The image reading device includes: an optical part, extending long in a direction; a case, having an accommodating portion for accommodating the optical part; and a light receiving component, accommodated in the case. The optical part is fixed in the accommodating portion through a first adhesive and a second adhesive with hardening time longer than that of the first adhesive.
Claims16
An image reading device, comprising:
- an optical part, comprises:
- a linear light source, extending long in a first direction;
- and
- a lens array, enabling light to converge on the light receiving component;
- a case having an accommodating portion for accommodating the optical part, the accommodating portion comprises:
- a lens accommodating portion for accommodating the lens array;
- and
- a light source accommodating portion for accommodating the linear light source, the light source accommodating portion comprises:
- a strip-shaped bottom surface overlapping with the linear light source when viewed from a third direction orthogonal to the first direction and a second direction;
- and
- a strip-shaped plane adjacent to the strip-shaped bottom surface in the second direction and not overlapping with the linear light source when view from the third direction;
- and
- a light receiving component accommodated in the case;
- wherein the optical part is fixed in the accommodating portion through a first adhesive and a second adhesive, a hardening time of the second adhesive is longer than a hardening time of the first adhesive, the strip-shaped s lane is coated with the first adhesive, and the strip-shaped bottom surface is coated with the second adhesive.
