<p><P>PROBLEM TO BE SOLVED: To provide an optical position detection device capable of optically and accurately detecting a sinking depth when an object body presses a translucent member, and to provide a hand device including the same and a touch panel. <P>SOLUTION: In the optical position detection device 10, a light source device 11 emits detection light L2 from a second surface 42 side opposite a first surface 41 side where the object body Ob is located in a translucent member 40, and the reflected light L3 reflected on the object body Ob and transmitted to the second surface 42 side of the translucent member 40 is detected by a photodetector 30. The first surface 41 of the translucent member 40 has elasticity and sucking properties to the object body Ob. Thus, in the optical position detection device 10, a sinking depth at the moment when the object body Ob and the translucent member 40 are brought into contact with each other and when the object body Ob presses the translucent member 40 is detected accurately. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
