Patent attributes
An image information detecting cassette accommodating an image information detecting section capable of reducing its power consumption when not used. When the handle of the cassette is gripped by the operator for carrying, the handle grip signal is outputted from the handle grip detecting section. If the readout signal from the scan/readout section, X-ray ready signal from the external system controller, and release signal from the release switch are not outputted, that is, when the cassette is carried and not used, it is determined to be the out-of-use state by the out-of-use determining means. The low power consumption mode is set by the control section, and the power supply to the image information detecting section, reading light emitting section, detecting section driving section, nonvolatile memory, X-ray buzzer, and matrix indicator is discontinued by the power supply suppressing section.
