Abstract: A first data taking section takes first detection results from a first wireless tag reader which detects the come and go of an electronic cassette into and out of a first service zone, and also takes second detection results from a second wireless tag reader which detects the come and go of an electronic cassette into and out of a second service zone. A first alert controller drives a first speaker to start an alert when the first alert controller determines on the basis of the first detection results that the electronic cassette has gone out the first service zone. After the start of alerting, the first alert controller stops driving the first speaker to interrupt the alert when first alert controller determines that the electronic cassette has come in either the first service zone or the second service zone.

Abstract: A monocoque-structured housing accommodates a photoelectric conversion panel, a scintillator, and a circuit board in this order from an X-ray incidence side. The scintillator contains cesium iodide and converts X-rays into visible light. The scintillator is vapor-deposited on the photoelectric conversion panel. A plurality of pixels that photoelectrically convert the visible light into charges are formed in the photoelectric conversion panel. A signal processor, which reads out the charge from each pixel and generates image data, is mounted on the circuit board. A gap layer is formed between the scintillator and the circuit board.

Abstract: Disclosed is a radiographic image detection device which prevents electrostatic charging without causing absorption loss of radiation. The radiographic image detection device has a solid-state detector 20, a wavelength conversion layer 21, and a support 22 arranged in this order from the incidence side of radiation. The wavelength conversion layer 21 converts radiation transmitted through the solid-state detector 20 to visible light. The solid-state detector 20 detects visible light to generate image data. The support 22 has a light reflection layer 22b and an antistatic resin film 22a. The antistatic resin film 22a prevents the support 22 from being electrostatically charged by friction or the like.
