Can be approached without being disturbed by the console 30. FIGS. 5 and 6 show a second embodiment of the present invention. The difference from the above embodiment lies in the structure of attaching the console 30 to the mounting table 10. The same parts as those in the first embodiment are denoted by the same reference numerals, and differences will be described. That is, the discs 51 are fixed to both ends of the support shaft 34 welded to the lower end of the support plate 33. Lock grooves 51a and 51b are formed at two positions 180 degrees apart on the outer periphery of each disk 51. The support shaft 34 penetrates each disk 51, and a connecting block 52 is rotatably attached to each penetrating end about the axis of the support shaft 34. The console 30 is fixed to both connecting blocks 52. Each connecting block 52 has a portion facing the outer periphery of the disc 51, and a lock pin 53 is inserted into a guide hole 52a formed in the facing portion so as to be able to reciprocate in the radial direction of the disc 51. Have been. Insert each lock pin 53 into the disk 5
A spring 54 for imparting elasticity toward the outer periphery of the spring 1 is inserted into the guide hole 52a. The lock pin 53 is inserted into one of the lock grooves 51a and 51b by its elasticity, and the rotation of the connection block 52 about the support shaft 34 is locked by this insertion. A connecting pin 61 is attached to each lock pin 53 in parallel with the support shaft 34. A long hole 52b communicating with the guide hole 52a is provided in each connection block 52 with the radial direction of the disk 51 as the longitudinal direction. The swing arm 55 is connected to each of the connection pins 61 protruding from each of the long holes 52b. Each swing arm 55 is connected to the connecting block 5.

It is preferable that the console can be disposed at a position where the console projects left and right from the mounting table to the other side and a position below the mounting table. Thereby, it is difficult to approach the mounting table from one of the left and right sides because both arms and the main body are in the way, and even if the console is provided on the left and right sides of the mounting table,
The elderly or critically ill patient on the bed can be easily transferred to the mounting table, and the left and right sides of the mounting table can approach the subject without being disturbed by the console. It becomes possible. In the present invention, the console rotates around an axis along the longitudinal direction of the mounting table, so that the console can be disposed at a position extending laterally from the mounting table and at a position below the mounting table. A guard that rotates along with the console is located on the inner side of the mounting table below the console when the console projects sideways from the mounting table, and is mounted above the console when the console projects below the mounting table. It is preferably provided so as to be located on the outer side of the table. Thus, in a state where the console is arranged below the mounting table, even if a part of the bed for carrying a patient or the like enters under the mounting table, it hits the guard first, and the console is moved from the side of the mounting table. In the overhanging state, even if a person on the mounting table moves and the limbs or the like jump out of the mounting table, the guard hits the guard first, so that the console lever and switch are protected without being damaged.
