Abstract:
1. An X-ray apparatus for X-raying a subject, comprising (A) a top board for supporting, or contactable by, the subject; (B) an X-ray emitting device for emitting X rays toward the subject on the top board; (C) an X-ray detecting device opposed to the X-ray emitting device across the top board for detecting X rays emitted from the X-ray emitting device and transmitted through the subject; (D) a storage device for storing X-raying conditions indicating conditions of X-ray emission from the X-ray emitting device; (E) a radiography start instruction input device for receiving X-ray radiography start inputs; (F) a drive instruction input device for receiving instruction inputs for driving at least one of the X-ray emitting device and the X-ray detecting device, and the top board; (G) a drive control device for performing drive control of at least one of the X-ray emitting device and the X-ray detecting device, and the top board, based on an instruction from the drive instruction input device; (H) an input detecting device for detecting a start instruction from the radiography start instruction input device or a drive instruction from the drive instruction input device during a sequential shooting; (I) an automatic exposure control device for starting, based on an input detection by the input detecting device, an X-ray emission from the X-ray emitting device on X-raying conditions read from the storage device, and for stopping the X-ray emission from the X-ray emitting device when an amount of transmitted X rays detected by the X-ray detecting device reaches a predetermined value; and (J) an X-raying condition fixing control device for carrying out controls to cause an X-ray emission from the X-ray emitting device on X-raying conditions effective when the X-ray emission is stopped by the automatic exposure control device, and turning off the automatic exposure control by the automatic exposure control device, until a next input is detected by the input detecting device.
