The storage box 5 has four free wheels 10 and can be moved by the storage box 5 alone. In addition, the storage box 5 is formed in a U shape as shown in FIG. 2, and the storage position of the cassette is provided at a location located on the side of the operator when the operator moves the apparatus. A loading port 21 and a taking-out port 22 for the cassette to the storage box 5 are provided in each storage unit. In the X-ray apparatus constituted by these, the movable carriage 1 is moved manually or electrically into a hospital room where a subject is present, and X-ray imaging is performed there.
[0010]
Next, a mechanism for connecting and releasing the movable carriage 1 and the storage box 5 will be described with reference to FIG.
[0011]
In FIG. 3, the storage box 5 is provided with a pin 13 for coupling the storage box 5 and the movable carriage 1, and the movable carriage 1 is provided with a groove for receiving a pin and whether the pin 13 has entered. A detector 6 is provided for detecting whether or not. A lever 11 is attached near the handle of the storage box 5, and the lever 11 and the pin 13 are connected by a wire 12. Therefore, by moving the lever 11, the pin 13 that connects the movable carriage 1 and the storage box 5 can be removed. Conversely, the movable carriage 1 and the storage box 5 can be connected.

[0013]
As a specific example of improving operability, the storage box unit is separated from the moving carriage, the storage box unit is moved to the dark room, and a film is loaded into a plurality of cassettes. The cassettes are inserted into the storage box unit, and the storage box unit is moved to the standby position of the movable carriage and connected.
Thereafter, the patient moves to the hospital room in a state where the moving cart and the storage box unit are connected to each other through the hospital corridor.
[0014]
When trying to take a picture with the device in the bed side of the hospital room, if the bed side is narrow and the mobile cart cannot be positioned with the mobile cart and the storage box unit connected, the mobile cart and the storage box The unit is disconnected, the storage box unit is disconnected, and only the main body is moved between the beds. At this time, the storage box unit is stopped in a large space in the hallway or hospital room.
[0015]
As a result, since the movable carriage and the storage box unit can be moved independently, the X-ray apparatus can be linearly moved or turned in a small moving room in a narrow hospital room or the like, so that the operability in a narrow place such as a bedside is possible improves.
[0016]
In addition, since the mobile X-ray apparatus in which the storage box is integrally attached to the conventional mobile carriage has a large size, the forward visibility of the operator is poor, but the mobile X-ray apparatus of the present invention Has a structure in which the storage box unit is attached to the side of the operator, so that the operator can approach the front of the moving carriage, so that the visibility in the moving direction of the moving carriage is improved.
