Description

  The present invention relates to a mobile X-ray apparatus having an operation handle that is gripped by an operator when moved.

  In a conventional round-trip X-ray imaging apparatus, a cart having a plurality of wheels is equipped with an X-ray tube, a motor that drives the wheels, and a control unit that controls the driving of the motors. The carriage is provided with an operation handle that is held by an operator when the carriage is moved. When it is detected by the sensor that the operator has pushed the operation handle forward, the motor is driven by the control unit and the carriage moves forward.

  Further, when the operator holds the operation handle and operates the brake release switch, the brake is released and the carriage is allowed to travel. When the operator releases his / her hand from the operation handle, the brake release switch is turned off, and traveling of the carriage is prohibited (for example, see Patent Document 1).

JP 2008-173256 A

  In the conventional X-ray imaging apparatus for round trips as described above, since the carriage is prohibited from traveling when the operator removes his / her hand from the operation handle (deadman system), the operation is required to run the carriage. It is necessary for the person to hold the operation handle and keep pressing the brake release switch. On the other hand, since the thickness of the operation handle is designed according to the average hand size, an operator handle with a relatively large hand size can be used when the cart is running. It will be a burden to keep gripping. In particular, when a reciprocation of several km or more is required, it is a heavy burden to continue to hold an operation handle that does not fit the size of the operator's hand.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a mobile X-ray apparatus that can reduce the burden on the operator during traveling and improve operability. To do.

  A mobile X-ray apparatus according to the present invention includes a carriage having a plurality of wheels, an X-ray apparatus body mounted on the carriage, a traveling motor mounted on the carriage and driving the wheels, a handle body, and the carriage. A brake release switch for releasing the brake that prevents the vehicle from traveling, and has an operation handle provided on the carriage, and the operation handle has a cross-sectional size perpendicular to the length direction of the handle body. A size adjusting mechanism for changing the height is provided.

  In the mobile X-ray apparatus of the present invention, the size adjustment mechanism for changing the size of the cross section perpendicular to the length direction of the handle body is provided on the operation handle, so the burden on the operator during traveling is reduced. In addition, operability can be improved.
