## Abstract

A diagnostic device system has a weight-reduced rechargeable battery. When a portable radiographic apparatus and a portable X-ray source are carried to and used for imaging at a private home or a care home, the portable radiographic apparatus and the portable X-ray source are loaded on an automobile. When the charge amount of rechargeable batteries for operation housed in the portable radiographic apparatus or the portable X-ray source loaded on the automobile is low, or when there are plural destinations and the charge amount of the rechargeable batteries becomes low, a rechargeable battery for charging mounted on the automobile is used to charge the rechargeable batteries for operation while traveling. Because the rechargeable batteries for operation are charged while traveling, a large number of rechargeable batteries for operation does not need to be charged in advance, whereby the weight of the rechargeable batteries for operation can be reduced.

## Claims

### Claim 1

A diagnostic device system comprising:
a diagnostic device that is supplied with electric power for operation and is used for diagnosing diseases of humans or animals;
a rechargeable battery for operation that is charged by a rechargeable battery for charging, wherein the rechargeable battery for charging is mounted on a vehicle and is used to charge the rechargeable battery for operation and to realize the functions of the vehicle and the rechargeable battery for operation supplies electric power to the diagnostic device to operate the diagnostic device; and
an accommodating unit that houses the rechargeable battery for operation therein and corn rises an electric cable for supplying electric power from the housed rechargeable battery for operation to the diagnostic device.

### Claim 2 (depends on 1)

The diagnostic device system of claim 1, wherein the diagnostic device is at least one of a portable radiographic apparatus for recording a radiological image expressed by irradiated radiation or a portable X-ray source for irradiating radiation on the portable radiographic apparatus.

### Claim 3 (depends on 1)

The diagnostic device system of claim 1, wherein the vehicle on which the rechargeable battery for charging is mounted is an automobile.

### Claim 4 (depends on 2)

The diagnostic device system of claim 2, wherein the vehicle on which the rechargeable battery for charging is mounted is an automobile and the rechargeable battery for charging is used to realize the functions of the automobile.

### Claim 5 (depends on 1)

The diagnostic device system of claim 1, wherein the capacity of the rechargeable battery for operation is smaller than the capacity of the rechargeable battery for charging.

### Claim 6 (depends on 1)

The diagnostic device system of claim 1, wherein the rechargeable battery for operation has a larger self-discharging rate than the rechargeable battery for charging.

### Claim 7 (depends on 1)

The diagnostic device system of claim 1, wherein the rechargeable battery for operation is attachable to and detachable from the diagnostic device.
