    • An acceleration sensor is installed in an electronic cassette. The acceleration sensor detects a shake. When magnitude of the shake, measured using the acceleration sensor, is greater than or equal to a shake detection threshold value, a judging circuit of a shake detecting section turns off a switching element. An operation switching section is disconnected from an irradiation detecting section that detects a start of X-ray irradiation. Thus, an irradiation detection function of the irradiation detecting section is disabled. After a predetermined time, the judging circuit outputs an ON signal to the switching element to turn on the switching element. Thereby, the irradiation detecting section resumes the irradiation detection.
    • 加速度传感器安装在电子盒中。 加速度传感器检测到振动。 当使用加速度传感器测量的振动大小大于或等于抖动检测阈值时,抖动检测部分的判断电路关断开关元件。 操作切换部分与检测X射线照射开始的照射检测部分断开。 因此,照射检测部的照射检测功能被禁用。 在预定时间之后,判断电路向开关元件输出ON信号以接通开关元件。 由此,照射检测部恢复照射检测。

    • A radiographic image capturing system includes a radiographic image capture device, a radiation irradiation device, and a control device. The radiographic image capture device is capable of wired and wireless communications, and is capable of fluoroscopic imaging in which radiographic images are successively captured at notified synchronization timings or at a predetermined frame rate. The radiation irradiation device irradiates radiation toward the radiographic image capture device during fluoroscopic imaging, with continuous irradiation or pulse irradiation. The control device includes a wireless communication unit, a wired communication unit, and a controller that, if communication with the radiographic image capture device is performed by the wireless communication unit, prohibits fluoroscopic imaging with pulse irradiation in which the synchronization timings are notified to the radiographic image capture device and radiation is irradiated from the radiation irradiation device in pulses matching the notified synchronization timings.

    • When a first image capturing apparatus installed in an image capturing room is selected and a power supply switch of a radiation converter used in the first image capturing apparatus is turned on, a controller generates an image capturing apparatus identification signal for specifying the image capturing apparatus, and sends the identification signal together with ID information of the selected image capturing apparatus stored in an ID memory to a console in the image capturing room via a transceiver by wireless communications. The console reads image capturing conditions for the selected image capturing apparatus from an image capturing condition storage unit, and supplies the conditions to a radiation generator for recording a radiographic image in the radiation converter. The radiation generator controls a radiation source according to the supplied conditions to emit radiation for recording a desired radiographic image on a radiation conversion panel of the radiation converter.

    • An electronic cassette has a casing that houses a radiation converter thereinside. The radiation converter detects radiation from a radiation source that has been transmitted through a subject, and converts the radiation into radiographic image information. Plural handles are disposed on the casing of the electronic cassette, so that a person can grip the plural handles and carry the electronic cassette. Thus, the person can grip and carry the electronic cassette while dispersing the weight of the electronic cassette, so carrying the electronic cassette becomes easy. Further, when the person loads the electronic cassette into a shooting table or the like, the person can grip either of the plural handles and load the electronic cassette. For this reason, handling of the electronic cassette becomes easy.
