It is to provide a torque driver capable of bringing a marker into direct contact with a surface of a fastener member such as a screw to perform marking.A torque driver 1 is configured such that a case 10 is rotated relative to a main shaft 20 when a tightening force applied to the case 10 is transmitted to the main shaft 20 through a torque limiter section 30 and a tightening torque on a screw 80 engaged with a bit 70 attached to a coupler 60 fixed at a tip portion of the main shaft 20 reaches a torque value set in the torque limiter section 30. The torque driver 1 includes: a marker 54 extending from an inside of the coupler 60 to a tip portion of the bit 70 along a side surface of the bit 70; and a marker activating section 40 that allows the marker 54 to move forward by utilizing rotation of the case 10 relative to the main shaft 20 so that a marker tip portion 53 is brought into contact with the screw 80 to perform marking.

Provided is an X-ray fluoroscopic system capable of highly accurately performing tilting tracking or rotational tracking by a simple operation in an observation work without inputting a distance from the surface of a table and an observed point of an object of fluoroscopy and without performing a calibration operation for obtaining the distance in advance.In the X-ray fluoroscopic system having a tracking function of obtaining a moving amount of the table 2, which is necessary for performing tilting or rotational tracking, and moving the table, based on an arithmetic operation using a distance h obtained by totalizing a distance d from the surface of the table 2 to an observed point V, and a distance z from the surface of the table 2 to an X-ray focal point 1a, a defined value or arbitrary input value is used as an initial value of the distance h, and a shift amount of the observed point V occurred from tracking is used to update the distance h by specifying the observed point V on a screen after tracking, thereby tilt (rotation) tracking accuracy is gradually improved.
