PROBLEM TO BE SOLVED: To eliminate the need for a storage place at the time of nonuse of a stool by moving a supporting means to the front surface side of a setting means at the time of use and moving and retreating this supporting means to and from the flank or inside part of a setting means at the time of nonuse. SOLUTION: The stool 114 is mounted via a hinge unit 113 on the X-axis side of a radiographing base top plate 107. This hinge unit 113 which is easily rotatable on in one direction and has a locking mechanism like the hinge unit used for a back rest portion of, for example, a folding type legless chair is used. A rotation resisting means is disposed to prevent the casual change in the angle of the stool 114 by the raising and falling motion to an upright position, horizontal position and inverted tilting position of a table section 108. As a result, if the stool 114 is put to the upright position, this stool acts as the stool of the examinee 104 and if the stool is put to the horizontal position, the stool is usable as an auxiliary table for the table section 108. Further, if the stool is put to a hanging position, the stool may be put into a storage position. The need for a specific storage place may be eliminated. |
