Abstract: PROBLEM TO BE SOLVED: To provide a position probing device that detects the identifier of an object whose position is to be probed, and has a probing system for sending a signal corresponding to the identifier. SOLUTION: An object whose position is to be probed has an object position- indicating device 10 with a display 1. When a receiver 4 of an object-probing device receives a signal for information that the position of the object regarding the receiver 4 itself is searched, a controller 3 changes the display state of the display 1, thus optically displaying the reception of the signal. The object- probing device has a power supply 2 using periphery energy as power, and the display 1 is a bi-stable display such as rotary element display device.
