PROBLEM TO BE SOLVED: To provide a device for taking out efficiently an article discriminable by ID from a storage place therefor, and to provide a power-saving circuit used therefor.SOLUTION: In a detection circuit waiting with weak power at a normal time in the state where a capacitor is connected in series between an input terminal on one side of a comparator circuit and a +terminal of a power source, and sensing means is connected in series between the ground side and the capacitor, and checking agreement/disagreement of ID by starting by reception of a prescribed infrared ray, intensity of a reception wavelength is amplified substantially only during its recognition period.SELECTED DRAWING: Figure 3 |
