ABSTRACT:
An optical reading apparatus includes an optical scanning unit for emitting upward a scanning light beam to be used to optically read information on an article; and a supporting mechanism for supporting the optical scanning unit so that the optical scanning unit is maintained in a space over a surface of a counter in a state where a distance between the optical scanning unit and the surface of the counter is a predetermined length. An optical reading apparatus includes an optical scanning unit for emitting upward a main-scanning light beam to be used to optically read information on an article, and for emitting a sub-scanning light beam in a direction different from a direction in which the main-scanning light beam travels, the sub-scanning light beam being used to optically read information on an article, and a supporting mechanism for supporting the optical scanning unit so that the optical scanning unit is maintained in a space over a surface of a counter in a state where a distance between the optical scanning unit and the surface of the counter is a predetermined length.
