  • Patent number: 11045158
    Abstract: When a control unit 30 detects that the apparatus becomes a traveling mode, the control unit 30 stops the power supply from a power supply circuit 52 to an opening-degree sensor S2 of a collimator leaf and a distance sensor S3 for detecting the distance between an X-ray tube 11 and a subject. On the other hand, for an acceleration sensor S1 for measuring the acceleration of a collimator 12, power supply from the power supply circuit 52 is stopped. When the control unit 30 determines that the apparatus is not in the traveling mode, electric power is supplied to all of the acceleration sensor S1, the opening-degree sensor S2, and the distance sensor S3. As a result, power consumption can be reduced by constantly supplying electric power to the acceleration sensor S1 required to perform constant monitoring, and in the traveling mode, power supply to the opening-degree sensor S2 and the distance sensor S3 used when performing X-ray imaging is stopped, so that power consumption can be reduced.

  • Patent number: 10918349
    Abstract: In a first scenario, a third switch is opened when a first switch is opened to turn off the power supply provided to a device main body and a second switch is short-circuited. The third switch is opened as a result of the power supply provided to the main body controller being stopped. In a second scenario, the third switch is opened when the device main body is in a running state, the first and second switches are short-circuited, when a trolley is moved between hospital rooms. Whether or not the device main body is in a running state is recognized as a result of a lock unit sending a signal to the main body controller, said signal indicating that an arm has come in contact with the lock unit and the arm is arranged at a fixed position where the arm should be arranged when moving the trolley.

  • Patent number: 10893841
    Abstract: The radiography apparatus of the present invention includes a CPU 71 having a function of a lighting time limitation means to control the lighting time of light sources in such a way as to maintain a temperature at or below a predetermined temperature. In order to discriminate the type of light source connected to the device body, the setting of No. 5 pin on the CPU 71 to a high logic state or a low logic state is detected. This enables the detection of whether the light source connected to a control board 70 is a halogen lamp H or a light emitting diode (LED) L. Thus, the type of the light source is discriminated. The CPU 71 changes the controlled limiting lighting time based on the result of discrimination. This prevents the risk of incorrectly carrying out settings and enables the automatic setting for switching light sources.

  • Publication number: 20200330060
    Abstract: When a control unit 30 detects that the apparatus becomes a traveling mode, the control unit 30 stops the power supply from a power supply circuit 52 to an opening-degree sensor S2 of a collimator leaf and a distance sensor S3 for detecting the distance between an X-ray tube 11 and a subject. On the other hand, for an acceleration sensor S1 for measuring the acceleration of a collimator 12, power supply from the power supply circuit 52 is stopped. When the control unit 30 determines that the apparatus is not in the traveling mode, electric power is supplied to all of the acceleration sensor S1, the opening-degree sensor S2, and the distance sensor S3. As a result, power consumption can be reduced by constantly supplying electric power to the acceleration sensor S1 required to perform constant monitoring, and in the traveling mode, power supply to the opening-degree sensor S2 and the distance sensor S3 used when performing X-ray imaging is stopped, so that power consumption can be reduced.
