Abstract: In this diagnostic X-ray apparatus (1), a radius of a spiral pulley (63) is set to a radius that differs from a radius of an Archimedes' spiral so that a tensile force of the spring member (61) applied to a second wire rope (67b) and a weight on an X-ray generation unit (50) side applied to a first wire rope (67a) are balanced.

Abstract: The axial direction B of the spindle 64 for supporting the movable pulleys 58 and 59 is arranged at a position rotated about the axis of the shaft relative to the axial direction of the spindle 56. The axial direction B of the spindle 64 is arranged in a state of being inclined by a predetermined angle with respect to the axial direction A when the movable pulleys 58 and 59 are in the lifted position. This allows the movable pulleys 58 and 59 to be automatically moved to a position at which no stress is applied to the first wire rope 54.

Abstract: This X-ray apparatus for rounds includes an X-ray generator capable of moving up and down in a vertical direction, a holding frame that holds a compression spring or a tension spring that expands and contracts as the X-ray generator moves up and down such that the compression spring or the tension spring is expandable and contractable, that holds a wire rope that transmits an elastic force of the compression spring or the tension spring to the X-ray generator and a pulley around which the wire rope is wound and which rotates, and that supports the X-ray generator such that the X-ray generator is movable up and down, and a support column that extends in the vertical direction and houses the holding frame such that the holding frame is detachable and upwardly exposable.

Abstract: A portable radiation imaging apparatus improves visibility while moving by arranging the supporting column in the low-position. A base 46 is at a bottom end of a supporting column 41 and is fixed to turntable 78. A surface holding bearing 60 has an inner ring 61 and an outer ring 62 between the turntable 78 and a bottom plate 79. The inner ring 61 of the surface holding bearing 60 is fixed to the turntable 78 and the outer ring 62 is fixed to the bottom plate 79. The turntable 78 revolves with the supporting column 41 around the revolving center C, as the center, of the supporting column 41 and the turntable 78. An idler element 65 has a first circumference 63 and a second circumference 64 is installed to a circumference of the surface holding bearing 60. The revolving-side stopper 81 and the fixing-side stopper 82 regulate the idler element 65.

Abstract: In a state in which a ferrule 10 is sandwiched and fixed between a ferrule receiving part 20 and a ferrule pressing part 30, the ferrule 10 is urged toward the ferrule receiving part 20 side by an urging member 33. With this structure, without configuring such that the ferrule pressing part is screwed in the ferrule receiving part by rotating several times, the ferrule 10 can be pressed toward the ferrule receiving part 20 side by a sufficient pressing force by the urging force of the urging member 33. Therefore, the attaching work of the column 2 can be performed more easily.

Abstract: According to the present invention, a highly safe moving-type radiation device can be provided. In the case of a conventional configuration using tension springs, if a spring is severed, the fragments will separate from each other permanently. Therefore, the present invention uses compression spring 8a and 8b instead. According to the spring mechanism of the present invention, even if a shaft is about to move largely in accordance with the severing of a spring, fragments of the spring, which has become stuck each other and immovable, interfere and prevent the movement of the shaft. What has been devised in the present invention is a junction spring seat that links a plurality of compression springs 8a and 8b. With this, even in cases where the compression springs 8a and 8b are linked in series, the compression springs 8a and 8b will not be buckled.

Abstract: The present invention provides a moving type radiation device improved in usability. The stroke of an intermediate member in a conventional configuration can be increased when an effective diameter of a pinion with respect to an effective diameter of a lower sprocket is determined so that a magnitude of a relative movement that occurs when a lower sprocket and the pinion between an X-ray tube and the intermediate member becomes larger than the magnitude of the relative movement between the X-ray tube and the intermediate member. In the device according to the present invention, the intermediate member moves further toward the floor side than in a conventional device. The operator can move the device while feeling high operability in a state in which the visibility is not interrupted by the intermediate member.

Abstract: A ferrule container 1 is provided with a ferrule accommodating part 11 and a first column guide part 12. A ferrule is accommodated in the ferrule accommodating part 11. The first column guide part 12 guides a column so as to insert the column into the ferrule accommodated in the ferrule accommodating part 11. Guiding of the column by the first column guide part 12 enables the column to be smoothly and reliably inserted into the ferrule accommodated in the ferrule accommodating part 11. Consequently, unlike a case in which an operator inserts a column while pinching a ferrule with hand, the work of inserting a column into a ferrule can easily be performed.
