Abstract: A radiographic apparatus includes a radiation source for emitting radiation, a radiation source control unit for instructing the radiation source to emit the radiation, and a radiation detector for detecting the radiation. The radiation detector outputs real-time detection data when the radiation source emits the radiation intermittently or continuously, and outputs quiescence detection data when the radiation source emits still radiation. The quiescence detection data is acquired by the radiation source control unit controlling the radiation source to start emitting the radiation at a time earlier than a predicted point of time by a predetermined time calculated based on an estimated irradiation time.

Abstract: An X-ray equipment includes a movable carriage, an X-ray tube for irradiating an X-ray on a subject, and a cassette storage box for storing a cassette with a radiographic storage medium such as a film. In the X-ray equipment, when the cassette storage box is pulled and tilted, a gateway for the cassette is opened. When the cassette storage box is pushed back, the gateway is closed. The X-ray equipment further includes a storage box locking device for locking the cassette storage box in a state where the gateway is closed and for unlocking the cassette storage box when the locked state is released, and a locking release holding device for holding the storage box locking device in a released state.

Abstract: An X-ray device includes a cart, a pole vertically provided on the cart, and a telescopic-type extendable supporting arm. The extendable supporting arm is formed of a hollow first arm with one end attached to the pole, a hollow second arm inserted in the first arm to be horizontally movable therein, and a third arm inserted in the second arm to be horizontally movable therein. Also, an X-ray tube device is provided on one end of the third arm. The extendable supporting arm has a synchronous moving mechanism for horizontally moving the third arm according to a horizontal movement of the second arm, and an extension/contraction operating handle attached to the second arm.

Abstract: A mobile X-ray apparatus for a circuit examination, which includes an X-ray tube with a collimator, a mobile base having a pair of driven wheels, a holder attached and movable to the base, the holder holds the X-ray tube. A motor driver is disposed in the base which drives the wheels. An operation handle bar is disposed in the base providing a signal for driving the motor driver. An input means, separated from the handle bar, provides a signal for driving the motor driver slightly. A controller controls the motor driver according to the signal from the handle bar or the input means.

Abstract: In a mobile type X-ray apparatus, an input shaft of a cyclo-decelerator is connected to one end of a rotational shaft of a motor, and the other end of the rotational shaft is connected to an encoder and an electromagnetic brake. The cyclo-decelerator is attached to a frame. Also, a bearing is fitted in the frame, and a wheel hub is fitted between the bearing and a motor output shaft. A wheel is fixed to the wheel hub. By the cyclo-decelerating mechanism, a transmission of power is carried out among contact surfaces of an eccentric cam, epitrochoid teeth and rollers, so that the apparatus has a compact structure with a low noise and no backlash.
