Abstract:
The main power source unit of an image read-out device supplies power to an laser diode (LD) power supply unit of an electronic cassette through a contact. The LD power supply unit supplies the supplied power to a laser diode (LD), as power used for emitting laser light, and also supplies a portion of the supplied power to an LD power supply unit of the image read-out device through a contact. The power supplied to the LD power supply unit of the image read-out device is supplied as power for emitting laser light to an LD of the image read-out device. When there is a change in the relative position of the casings of the electronic cassette and the image read-out device, the contact and electrical continuation of the contacts breaks and laser light stops being emitted from the LDs.
