In a medical diagnostic device such as a radiation CT device, a radiation source and a radiation detector that face each other around the patient are rotated around the body axis of a subject placed on a bed, such as a patient. tomographic images can be obtained. In this case, if the top plate of the bed on which the patient is placed bends due to the patient's weight, and the patient's body protrudes from the radiation irradiation area, an accurate tomographic image cannot be obtained. Therefore, it is necessary that the top plate of the bed does not sag even under the load imposed by the patient. However, increasing the thickness of the top plate in order to eliminate deflection due to load not only reduces the transmittance of radiation but also increases the cost when manufacturing the bed.

に近い点で支持することが可能となる。 In FIG. 2, a patient as a subject is placed on the top plate 1. The top plate 1 on which the patient is placed is moved toward the examination position (to the left in the figure). Then, the tip of the top plate 1 is connected to the roller 1 attached to the lever 13.
5. The lever 13 is given a force to rotate counterclockwise around the pin 14, but the lever 13
The roller 16 attached to the middle part of the guide 18
Since it is located above, the roller 16 runs on the guide 18. At the same time, the support member 8 to which the lever 13 is attached is moved to the left against the tension spring 11. When the top plate 1 travels a certain distance, that is,
When the roller 16 attached to the middle part of the lever 13 that is in contact with the top plate 1 travels a certain distance on the guide 18, the roller 16 moves to the inclined part 19 of the guide 18.
drive along. Then lever 13 is connected to pin 14
The roller 15 provided at the tip of the lever 13 and the top plate 1 no longer come into contact with each other, and the lever 13 and the top plate 1 no longer engage with each other.
When the top plate 1 further moves to the left, the top plate 1 rests on a roller 9 provided at the tip of the support member 8. As a result, the roller 9 inspects the top plate 1 using an inspection device (not shown).
It becomes possible to support at a point close to .

元の状態に戻る。 Next, when the top plate 1 returns to its original state after the inspection is completed, first only the top plate 1 moves to the right. When the top plate 1 returns a certain distance, the top plate 1 that has been holding down the head of the roller 15 disappears, and the roller 16 starts moving up the slope 19 of the guide 18 due to the tension spring 11, that is, the lever 13 moves clockwise. The roller 15 contacts the end of the top plate 1. Further, as the top plate 1 returns, the support member 8 also returns to its original state due to the tension spring 11.
