摘要
In an optical position detection device, the XY coordinates of a target object are detected based on received light intensity of a light receiving section by forming a light intensity distribution, in which the intensity changes in a radiation angle range of detection light, with first and second light source modules. The first and second light source modules are separated from each other in the Z-axis direction, and the position of the target object in the Z-axis direction is detected based on the received light intensity of the light receiving section when forming the light intensity distribution in which the intensity is fixed in the radiation angle range of detection light.
