BASE FOR PHOTOFLUOROGRAPHY

摘要

PROBLEM TO BE SOLVED: To provide an under tube table type X-ray photofluorography base which enables vertically sliding of a snap shooting device and a balance weight smoothly by securing geometric and dimensional accuracy. SOLUTION: A counter weight 2 for balancing the gravity of a snap shooting device is placed into a hollow strut 203 with a rectangular cross section, members facing each other which form rails 205 and 204 for a guide inside and outside the strut 203 are made of an extruding material or a drawing material 206 and both the members and a plate metal 207 are fixed to form the strut 203. A snap shooting support 4 and the counter weight 2 are made slidable along the rails 205 and 204 for the guide thereby facilitating the advancing or retraction of the snap shooting device to the subject while achieving a lower working cost of the strut part.
