BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile X-ray apparatus for performing X-ray photography by visiting a hospital.

[0002]

2. Description of the Related Art In a conventional mobile device of this type, a storage battery (battery) built in the device is used as a power source for easy handling.

[0003]

However, in a device using a storage battery as a power source, power consumption in a state where the power source is turned on becomes a problem. In particular, in recent years, an apparatus equipped with a microcomputer or the like consumes a large amount of power while not actually taking a picture, and the use time per charge of the battery is shortened. In addition, there is a problem that if the power is forgotten to be turned off, the battery is over-discharged and the life of the battery is shortened.

An object of the present invention is to solve the above-mentioned problems and to provide a mobile X-ray imaging apparatus in which power is turned on only during X-ray imaging.

[0005]

Means for Solving the Problems To solve the above problems, the first configuration of the present invention is as follows. That is, in a mobile X-ray imaging apparatus in which a motor drive circuit and an X-ray controller are connected in parallel to a DC power supply, when the X-ray tube apparatus is running,
Or is fixed to the storage position, or away from the retracted position
And a circuit for opening and closing the power source of the X-ray control device based on the output.

In a second configuration, in addition to the first configuration, a delay operation circuit to which power is supplied when the X-ray tube device is at an imaging position , and the delay operation circuit is operated by operating a panel or a hand switch or the like. And resetting the supply of power to the X-ray controller after the elapse of the delay time.

[0007]

When the X-ray tube device is in the fixed position, no power is supplied to the control circuit, and the power consumption is very small. In addition, the operation of the delay operation circuit automatically turns off the power unless X-ray imaging is performed for a certain period of time, so that there is no overdischarge of the battery due to forgetting to switch off.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to an embodiment shown in the drawings.

In FIG. 1, a battery 1 as a DC power supply is shown.
2, the motor drive circuit 13 and the X-ray controller 1 are connected in parallel. 8 is a power switch and 15 is a running switch. Here, a timer circuit 14 is connected to the X-ray controller 1 in parallel, and a timer contact 14a is connected to the X-ray controller 1 in series. Also, when the contact 11a of the microswitch 11 is X
The X-ray controller 1 and the timer circuit 14 are connected in series, and the microswitch 11 is provided on the side of the X-ray controller 1 at a position where the arm 3 is folded up and down along the side.

Next, an operation state will be described. The mobile X-ray imaging apparatus normally travels through the X-ray tube apparatus 4 as shown in FIG.
It is stored in a fixed state at the storage position . here,
The power ON / OFF switch 8 on the panel (not shown)
FF, and power is not supplied from the battery 12 at all. When the operator turns on the power ON / OFF switch 8, power is supplied to the motor drive circuit 13, and the motor can be moved by operating the handle. At this point, no power is supplied to the X-ray controller 1 and the power supply from the battery 12 is slight.

When the device reaches the vicinity of the subject, the operator removes the gripping rod 16 from the hook 17 and pulls it up. The arm 3 extends forward and horizontally, removes the X-ray tube device 4 from the storage position, and sets the X-ray tube device 4 at the imaging position. . By this operation, the microswitch 11 separated from the arm 3 has its contact 11a
Is closed, and power is supplied to the timer circuit 14 and the X-ray controller 1.

A panel (not shown) displays KV (voltage) and mAs (tube current time product) indications, and displays KV and mA.
Setting of imaging conditions and X-ray imaging by an s setting device (not shown) can be performed.

When the predetermined imaging is completed, the X-ray tube device 4
To the storage position. By this operation, the contact 11a of the micro switch 11 is opened, and the power supply to the timer circuit 14 and the X-ray controller 1 is cut off.

As described above, since power is supplied to the X-ray controller 1 only at the time of radiography, there is no wasteful power consumption of the battery 12. The timer circuit 14 starts counting at the same time as the power is supplied, but is reset by operating a hand switch (not shown) for X-ray imaging. Start counting. If the hand switch is not operated for a predetermined time (for example, 30 minutes), the contact of the timer circuit is opened, and the power supply to the X-ray controller 1 is cut off.

The detection means such as the microswitch 11 may be provided on the upper surface of the X-ray controller 1 corresponding to the storage position of the X-ray tube device 4. In the above embodiment, the reset of the timer 14 is performed by the operation of the hand switch. However, various switches (for example, KV, mAs
(Setting switch).

The present invention is not limited to the above-described embodiments and embodiments, but includes various modifications without departing from the spirit and scope of the utility model registration request.

[0017]

[Effect of the Invention] When the X-ray tube device is in the storage position, no power is supplied to the control circuit, and the power consumption is extremely small. If the X-ray imaging is not performed for a certain period of time, the power is automatically turned off, and there is no overdischarge of the battery due to forgetting to turn off the switch.
