Description of the Related Art FIG. 9 is a schematic diagram showing a basic configuration of a conventional X-ray fluoroscope used in a medical facility such as a hospital on a fluoroscopic table side. As shown in FIG. 9A, a conventional X-ray fluoroscope has a subject (patient) M placed thereon, and a top 51 whose position and posture can be changed, and a top 51 facing the top 51 sandwiched therebetween. An X-ray tube 53 and an image intensifier (I / I tube) 54 as an X-ray detector, and an X-ray imaging mechanism 52 installed on a top plate 51 are provided on the see-through table side. Then, this X-ray fluoroscopic apparatus is shown in FIG.
As shown in (b), by changing the position and posture of the top 51, the top 51 is moved up and down, and the X-ray tube 53 is moved.
A transmission X-ray image of the subject M, which is generated by X-rays irradiating the subject M from, is detected by the I / I tube 54 and output to the subsequent stage as X-ray detection data, while being output from the I / I tube 54 An X-ray fluoroscopic image is created and displayed based on the X-ray detection data.

従来のＸ線透視装置の場合、天板５１に被検体を乗り降

５１に楽に乗り降りさせられないと、Ｘ線透視がスムー
ズに進められない。However, in the case of the above-mentioned conventional X-ray fluoroscope, there is a problem that it is not easy for the subject to get on and off the top board 51. Unless the subject can easily get on and off the top board 51, the X-ray fluoroscopy cannot proceed smoothly.

のである。Specifically, when the subject M is a healthy adult, for example, even if the state of the tabletop 51 and the X-ray imaging mechanism 52 is not suitable for getting on and off, there is no inconvenience. However, when the subject M is a care recipient such as an elderly person or an injured person or a child, if the state of the table 51 or the X-ray imaging mechanism 52 is inappropriate for getting on and off, getting on and off the table 51 becomes difficult. . In other words, it is impossible for the care recipient or child to get on and off the top 51 whose height is not appropriate, and the X-ray imaging mechanism 52 installed on the top 51 helps the care recipient and child to get on and off. It interferes with the caregiver's work.

である。Of course, if the state of the table 51 or the X-ray imaging mechanism 52 is inappropriate for getting on and off the table 51, the operator operates the console (not shown) by manual operation (manual operation).
To adjust the height of the top board 51 and the position of the X-ray imaging mechanism 52, but this adjustment is not easy for the operator. In the case of an X-ray fluoroscopy apparatus in which the position and posture of the top 51 are greatly changed for the purpose of raising and lowering, the state of the top 51 and the X-ray imaging mechanism 52 when the subject M gets on and off the top 51 is constant. The operation of manually changing the state of the top board 51 and the X-ray imaging mechanism 52 to a state just suitable for getting on and off the next subject M takes a lot of time and labor, and is considerably troublesome for the operator. It is a burden.
