The accessory holding groove 12 includes a compression band for fixing the patient, an irrigator table as a hook for performing infusion, a cassette holder for side photographing, a head photographing table for photographing the head, a shoulder rest, a backrest, and the like. A groove for fixing the accessory device to an arbitrary position on the top plate 2, and is provided on a side surface of the grip portion 13 so that liquid or the like flowing on the top plate 2 does not enter. The cross-sectional shape of the grip 13 is substantially quadrilateral,
Its size is such that the fingertips are slightly separated from each other when the fingertips are gripped by the palm of a person's hand. Therefore, when the patient on the top plate 2 unknowingly holds the grip 13, the tip of the index finger or little finger comes into contact with the root 14 of the grip 13. A switch holding groove 16 is formed on the lower surface of the upper flat portion 8, at a position where the tips of the fingers gripped by the patient cannot reach, and further deeper than the root portion 14.

FIG. 6 is a partial sectional view showing a state in which the side frame member 7 is fixed to the side edge of the mounting plate 6. A groove into which the flange 9 of the side frame member 7 bites is formed on the side surface of the mounting plate 6, and the flange 9 is fitted into the groove. The lower edge 6 ′ of the mounting plate 6 extends into the space 15 of the side frame member 7.

A brake operation switch 17 is provided in the switch holding groove 16 over the entire length of the side frame member 7. The operator operates the brake operation switch 17 so that the operator turns his hand to the lower side of the gripper 13 and consciously touches the fingertip.
It is provided at a portion where the fingertip reaches when the fingertip is further extended than 4. When the fingertip slightly presses any part of the brake operation switch 17, any type of switch may be used as long as the switch operates, but the membrane switch is inexpensive and easy to handle. Can be mentioned.

The membrane switch is configured as follows. That is, fixed contacts are formed in a comb-like shape by, for example, gold plating on almost the entire surface of a synthetic resin plate serving as a fixed substrate which is cut into an elongated shape so as to be inserted into the switch holding groove 16. A spacer made of a synthetic resin plate having a hole through which the fixed contact can be seen is overlaid on the surface of the substrate on which the fixed contact is printed. On the upper surface of the spacer, a movable plate in which a movable contact facing the fixed contact formed on the fixed substrate is formed by gold plating is overlapped, and the fixed substrate, the spacer and the movable plate are bonded.

Since the membrane switch provided in the switch holding groove 16 is normally held flat by the elastic force of the movable plate and the spacer is interposed, the movable contact of the movable plate and the fixed contact of the fixed substrate are not in contact with each other. It is in the state of. Then, when the operator's finger slightly presses the movable plate, the movable plate protrudes, and the movable contact of the movable plate comes into contact with the fixed contact of the fixed substrate through the window of the spacer, and the switch is turned on. Of course, the electric brake is released by this switch-on, and the top board 2 can move freely.

When the operator's finger leaves the movable plate,
Due to this elasticity, the movable plate returns to the flat state, the contact between the fixed contact and the movable contact is released, the electric brake is applied,
The top plate 2 is fixed.

When a patient placed on the top 2 seeks to support the body, such as when trying to move the patient's own body or when getting up, the patient holds the patient. Clamp the part 13. As described above, the size of the cross section of the grip portion 13 is, when gripped by the palm of a human hand,
Since the fingertips are formed in such a size that the fingertips are slightly separated from each other, when the patient on the top plate 2 unknowingly grips the gripping portion 13, the tip of the index finger or the little finger becomes the root 1 of the gripping portion 13.
The fingertip does not reach the brake operation switch 17 only by touching the brake operation switch 4. Therefore, there is no possibility that the patient accidentally releases the electric brake and the top board 2 moves unexpectedly.

When the operator intends to move the top board 2, the operator first turns the palm up, turns it up, and inserts a fingertip over the back side of the grip 13. For this reason, the fingertip reaches the brake operation switch 17 and can be operated with the fingertip. Then, the top plate 2 is moved to a desired position while pressing the brake operation switch 17 with a fingertip to release the electric brake.
, The electric brake is operated to fix the top board 2, and X-ray imaging is performed.

In the above embodiment, the narrowed entrance edges of the accessory holding groove 12 having a convex cross section are parallel to each other. In this mode, when a large amount of liquid flows from the top surface of the top plate, there is a possibility that the liquid flows into the accessory holding groove. In order to remedy such inconvenience, in another embodiment of the present invention, for example, as shown in FIG. 7, the upper edge and the lower edge of the narrowed entrance of the accessory holding groove 12 are provided from the inside to the outside. The tapers 18 and 19 are provided so as to prevent liquid flowing from the upper surface of the top plate from flowing into the accessory holding groove 12. Further, as shown in FIG. 8, the upper tapered portion may be formed as a liquid cutting groove 18 ', or as shown in FIG. 9, a liquidproof ridge 19' may be used instead of the lower tapered portion. Such a taper, a liquid cut groove, and a liquid prevention ridge are referred to as a liquid blocking portion.
