An image sensor unit (1) includes: a plurality of first light guide bodies (22) that linearize light emitted by light sources (21, 31) and project, onto a reading object (P), such linear light which is longitudinally long; a plurality of holding members (4) that hold, on a frame (16), each of the plurality of first light guide bodies (22); and an image sensor (141) that detects light from the reading object (P). The plurality of first light guide bodies (22) are disposed parallel to each other. Within a range, in the longitudinal direction of the first light guide bodies (22), in which the image sensor (141) detects light from the reading object (P), the main scanning-direction center position of the plurality of holding members (4) that hold one of the first light guide bodies (22) and the main scanning-direction center position of the plurality of holding members (4) that hold another light guide body different from such one light guide body (22) are mutually offset. |
