The handle is a rod-shaped member laid in the left-right direction, and its support is provided at the center. That is,
The handle of the device of the present invention is in the form of a bicycle handle which is extremely ordinary in the operation method, and its both ends are completely opened. Therefore, when it is easier to move the handlebars to the left and right by gripping the left and right ends of the handlebars, this can be done, and the operation for the lateral movements is generally simplified. In addition, the handle is like a bicycle handle for straight forward / backward operation (one center-supported handle laid horizontally)
In addition, since it can be tilted in the front-rear direction or horizontally moved, the left and right wobbles do not occur during traveling, and the operation becomes simple. As a result, the entire traveling operation can be carried out smoothly and smoothly, and the burden on the operator during traveling is reduced. In addition, the pair of detectors detects the direction and magnitude of tilting in the front-rear direction or horizontal movement of the upper end side of the handle support rod and rotation around the axis (including twisting) or tilting in the left-right direction, and outputs an electrical signal. And outputs them separately to the drive control system of the pair of motors for driving the main wheels. Thereby, it can be applied to the existing drive control circuit. Here, the above-described movement of the upper end side of the handle support rod also means movement of the handle when the handle is operated, and therefore the detector detects the handle operation (direction, etc.) and its operation amount. It will be.

FIG. 3 is a perspective view showing a third embodiment of an operating device for an electric carriage for a mobile X-ray device according to the present invention.
In FIG. 3, reference numeral 83 is a bar-shaped handle laid in the left-right direction, 93 is a handle support rod composed of a torsion bar 32 having an upper end connected to a central portion of the handle 83 and a lower end fixed to a predetermined handle mounting portion, Reference numeral 11 is a front-back motion detector including a front-back motion detection strain gauge 33 that detects an operation force in the front-back direction of the handle 83, and 12 is a handle 8.
3 is a rotational motion detector composed of a rotational motion detection strain gauge 34 for detecting a rotational (twisting) operation force in the left-right direction.
Front-back motion detection strain gauge 3 which constitutes the front-back motion detector 11
3 is stretched linearly in the axial direction (vertical direction in the figure) of the torsion bar 32 (handle support rod 93),
The operation force in the front-back direction causes the torsion bar 32 to expand and contract due to a slight bend, thereby changing the resistance value and detecting the front-back movement. Further, the rotational movement detecting strain gauge 34 constituting the rotational movement detector 12 is wound around the torsion bar 32 in the axial direction (vertical direction in the drawing) in a spiral shape and stretched by the torsional force of the handle 38 in the lateral direction. Bar 3
2 is expanded and contracted due to a slight twist to generate a resistance value change, and the rotational movement is detected. According to this, when the handle 83 is pushed and pulled in the front-rear direction (arrow N direction) to move the electric carriage (not shown) forward and backward, the torsion bar 32 receives an operation force in the front-rear direction with the fixed portion 100 as a fulcrum. The forward / backward movement detection strain gauge 33 detects the change in the resistance value to detect that the handle 83 has been operated in the front-rear direction and the operation amount thereof. Further, when the handlebar 83 is rotated about the torsion bar 32 as shown by an arrow mark in order to change the course of the electric carriage (not shown) in the left-right direction, the torsion bar 32 rotates around the axis around the fixed portion 100 as a fulcrum. When the rotational movement detection strain gauge 34 detects the change in the resistance value due to the operation force, the operation of the handle 83 in the left-right direction and the operation amount thereof are detected. According to this configuration, even if the operator operates the handle 83, only a very small displacement can be obtained because the torsion bar 32 is used. In other words, the displacement of the handle 83 is very small, and when the handle is operated, the discomfort that occurs in the conventional device in which the handle 83 greatly moves in the escape direction is not generated.

FIG. 4 is a perspective view for explaining a handle support rod 93 having the same function as the torsion bar 32 in FIG.
Here, the handle 83 is supported similarly to the torsion bar 32 by using the spring member 35. According to this supporting method, the spring member 35 flexes freely in the front-rear direction, the left-right direction, or the rotation direction around the lower end fixing portion 100, and the operation direction and the operation amount of the handle 83 by the strain gauges 33 and 34 are detected. The arrow w indicates the operation of the handle 83 in the front-rear direction, which causes the handle 83 to flex and move forward and backward as indicated by the chain double-dashed line.
