Claims

[Scope of utility model registration request]

An X-ray photographic device in which a cassette holder for attaching a cassette can be slid between a fluoroscopy position and an imaging position along a rail provided in the housing of the X-ray photographic device attached to the X-ray photographing device, the slide a first detector for detecting whether or not the cassette holder is in the fluoroscopic position; a second detector for detecting whether or not the cassette holder is in the imaging position and controlling the X-ray irradiation circuit intermittently; , a third detector detects whether or not a cassette is attached to the cassette holder located at the fluoroscopic position; and a third detector detects the attachment state of the cassette; A memory circuit that stores the state and controls the on/off of the X-ray irradiation circuit is provided, and when X-ray imaging is completed with the cassette holder in the imaging position, it stores that the cassette is in the attached state. This X-ray machine is equipped with a double exposure prevention mechanism that prevents double exposure on a cassette film that has already been exposed to X-rays by clearing the memory contents of the memory circuit and controlling the opening of the X-ray irradiation circuit. Line speedgraph device.
