摘要： An X-ray diagnostic device has an attachment-and-detachment detection element that detects an attachment-and-detachment of the attachment-and-detachment member, a rotation detection element that detects the rotation of the motor, a torque adjustment element that adjusts the torque of the motor, and a torque detection element that detects the torque when the rotation of the motor suspends; wherein when attachment-and-detachment is detected, the brake is released; when the brake is released, the rotation of the motor due to an out of balance condition between the up-and-down moving element and the counterweight is detected and the motor torques is adjusted so as to suspend the detected rotation of the motor; the torque when the rotation of the motor suspends is continuously provided, so that the balance between the up-and-down moving element and the counterweight can be kept positioned.

摘要： 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.

摘要： An X-ray imaging apparatus includes an X-ray source, a detector for detecting X-rays, an imaging unit, an operation unit, a notification unit, and a control unit. The control unit generates an image of an inside of an examination room. Further, when detecting that a person other than a subject is present in the examination room based on the image of the inside of the examination room, the control unit performs control to issue caution information indicating that a person other than a subject is present in the examination room.

摘要： 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.

摘要： 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.

摘要： Provided is an X-ray imaging apparatus equipped with an LED driver circuit capable of properly and safely lighting an LED lamp even when an LED driver circuit is connected to any one of a plurality of internal power supplies different in voltage in the case of using an LED lamp as a collimator lamp. The LED driver circuit is provided with a rectifier circuit, a smoothing circuit, an input voltage level detector, a power connection switching unit for switching a change-over switch, and a DC-DC converter circuit. The DC-DC converter circuit is composed of a current control type DC chopper circuit and configured to measure the current from the voltage of both ends of a resistor and perform ON/OFF control of a transistor on the basis of the current to thereby function as a step-up/down chopper circuit or step-down chopper circuit.

摘要： A mobile X-ray imaging apparatus has an angle sensor and a movement calculation circuit that controls the driving of drive wheels based on the turning angle of auxiliary wheels relative to a straight moving direction of the base unit when a fine movement switch instructs movement of the base unit in the fine movement mode. The turning angle of auxiliary wheels is detected by a turning angle sensor and the rotation of the pair of drive wheels is controlled by the movement calculation circuit as the auxiliary wheels turns to the straight moving direction.
