- the buffer member 22C When the buffer member 22C is disposed, the load applied to the glass substrate 213 and the like is dispersed. However, when a sudden impact is applied from the side of the cassette type detector 1, the glass substrate 213 is easily displaced from the base 22. Therefore, by disposing the buffer member 22C and providing a gap T between the end of the glass substrate 213 and the side wall 22A of the base 22 in the same manner as in FIG. 6, dispersion of the load applied to the glass substrate 213 and the glass substrate It is possible to achieve both prevention of damage of 213.

Sudden impact may be applied to. After an impact is applied to the cassette type detector 1, the user may not be able to determine whether or not the cassette type detector 1 can operate normally. For example, even if a part of the detection unit 212 is damaged by an impact, a radiographic image detection operation is possible as long as the detection unit 212 does not have an electrical failure. Will continue to perform detection without recognizing a failure.
- the manufacturer specifies the cumulative number of impacts applied to the cassette type detector 1 (for example, the number of drops) from the viewpoint of durability, how many times the impact is applied to the cassette type detector 1.

When the power supply unit 105 is turned off, the sub power supply unit 106 supplies power to the control unit 101, the acceleration sensor 107, and the like.
- the acceleration sensor 107 is, for example, a two-axis type that detects acceleration in the X-axis direction and the Y-axis direction, or a three-axis type that detects acceleration in the X-axis direction, the Y-axis direction, and the Z-axis direction. Based on the waveform of the output signal from the acceleration sensor 107, it is possible to detect that an impact has been applied to the cassette type detector 1. Specifically, the peak value of the waveform of the output signal in the acceleration sensor 107 is low unless an impact is applied to the cassette type detector 1, but the peak value of the waveform increases when an impact is applied to the cassette type detector 1. By detecting this change in peak value, it is possible to detect that an impact has been applied to the cassette type detector 1.
- the number of times when the peak value of the waveform is greater than or equal to the reference value is counted, and the number of times is stored in the storage unit 104.

- the power supply unit 105 of the cassette type detector 1 When the power supply unit 105 of the cassette type detector 1 is turned on, the cumulative number of impacts (history information) stored in the storage unit 104 is checked. If the cumulative number is less than the reference number, the power supply unit 105 is turned on as it is. If the cumulative number is equal to or greater than the reference number, the cassette-type detector 1 has a high probability of failure. A warning is displayed on a device that is communicating through the communication unit 4, and the power supply unit 105 is turned off.
- the power supply unit 105 of the cassette type detector 1 When the power supply unit 105 of the cassette type detector 1 is ON, the waveform of the output signal from the acceleration sensor 107 is monitored. If it is determined that the peak value of the waveform is greater than or equal to the first reference value, it is determined that a considerably large impact has been applied to the cassette type detector 1, and the probability that the cassette type detector 1 has failed is high, so the indicator 53 is warned.
- the power supply unit 105 is turned off by displaying a color or displaying a warning on a device communicating via the wireless communication unit 4.
- the cassette type detector 1 performs self-analysis, and if a failure is found somewhere, a warning color is similarly displayed on the indicator 53. Or a warning is displayed on a device communicating via the wireless communication unit 4 to turn off the power supply unit 105. If no failure is found, the power supply unit 105 is turned on as it is.
- the cumulative number of impacts applied to the cassette type detector 1 is increased by 1 and the cumulative number Is less than the reference number of times, the probability that the cassette type detector 1 has failed is low, so the power supply unit 105 is turned on as it is, and if it is greater than the reference number, the probability that the cassette type detector 1 has failed is high.
- a warning color is displayed on 53, or a warning is displayed on a device communicating via the wireless communication unit 4, so that the power supply unit 105 is turned off.
