Abstract
A plurality of edges of sensor substrates are connected in a longitudinal direction in a sensor substrate unit. Farthest tips of sensor chips at the edges of the sensor substrates are positioned inside of farthest edges of the edges in the longitudinal direction. The edges of the connected sensor substrates overlap each other in a thickness direction of the sensor substrates in plan view.
Claims10
An image sensor unit comprising:
- a light source configured to illuminate an object to be read;
- a sensor substrate unit connecting a plurality of sensor substrates comprising a plurality of sensor chips arranged and mounted in a line in a longitudinal direction;
- a light condenser that focuses light from the object to be read on the sensor substrate unit;
- and
- a supporting body that supports the light source, the sensor substrate unit, and the light condenser, wherein
- edges of the connected sensor substrates are brought into close contact with each other in the sensor substrate unit,
- farthest tips of the sensor chips at the edges are positioned inside of farthest edges of the edges in the longitudinal direction of the sensor substrates,
- the edges of the connected sensor substrates overlap each other in a thickness direction of the sensor substrates in plan view, and
- the edges are formed to protrude from substrate bodies of the sensor substrates, parallel to mounting surfaces of the sensor substrates, and the edges are thinner than a thickness of the substrate bodies.
