In an optical coordinate input apparatus, a body includes an opening portion adjacent to a reflective surface, and a circuit board is installed in the body. An optical sensor module is installed in the body adjacent to the opening and separately from the circuit board, and has a light-receiving surface, of which an incident optical axis is inclined with respect to the reflective surface, and a light source, of which an exiting optical axis is inclined with respect to the incident optical axis. Accordingly, the circuit board is easily positioned in the body irrespective of optical and mechanical characteristics of the optical sensor module. |
