1. An object recognition device, comprising:
a pair of holding bodies extending in one direction, and facing each other via a space located on a side of the pair of the holding bodies which across with the one direction;
a plurality of light sources that is attached to at least one of the holding bodies along the one direction, and applies light toward at least a part of the space, a front of the space, and a back of the space;
an optical sensor that is attached to at least another of the holding bodies, and has at least a part of a visual field facing in at least a part of the space, the front of the space, and the back of the space; and
a pair of guide members that can expand and contract for alignment of the pair of holding bodies,
wherein one end and another end of one of the pair of guide members are each fixed to an upper end of one of the pair of holding bodies and a lower end of another of the pair of holding bodies,
one end and another end of another of the pair of guide members are each fixed to an upper end of the another of the pair of holding bodies and a lower end of the one of the pair of holding bodies,
the pair of guide members are provided as to intersect each other at a center of each of the one and the another of the pair of guide members.
