Abstract

Provided is a radiation image detecting system including a cassette type radiation image detecting apparatus capable of being driven by electric power supplied from a built-in battery; a charge controlling circuit to control charging of the battery; a cradle supplying electric power to the radiation image detecting apparatus; and a cable supplying electric power to the radiation image detecting apparatus, wherein the radiation image detecting apparatus includes a connection section being electrically connected to each of the cradle and the cable to receive the electric power; the battery is charged by the cradle being connected to the connection section and by the cable being connected to the connection section; and the charge controlling circuit switches a charging current between a time when the cradle is connected to the connection section and a time when the cable is connected to the connection section.

Claims

1. A radiation image detecting system comprising:

a cassette type radiation image detecting apparatus capable of being driven by electric power supplied from a built-in battery which supplies the electric power to each of function sections;

a charge controlling circuit to control charging of the battery;

a cradle supplying electric power from an outside to the radiation image detecting apparatus by placing the radiation image detecting apparatus thereon; and

a cable capable of supplying electric power from the outside to the radiation image detecting apparatus by being connected to the radiation image detecting apparatus, wherein

the radiation image detecting apparatus includes a connection section being electrically connected to each of the cradle and the cable to receive the electric power;

the battery is charged by the cradle being connected to the connection section and by the cable being connected to the connection section; and

the charge controlling circuit switches a charging current between a time when the cradle is connected to the connection section and a time when the cable is connected to the connection section.

2. The radiation image detecting system according to claim 1, wherein the charge controlling circuit is provided inside the cradle.

3. The radiation image detecting system according to claim 1, further comprising:

detection section for detecting which of the cradle and the cable is connected to the connection section, wherein

the charge controlling circuit switches the charging current according to a detection result of the detection section.

4. The radiation image detecting system according to claim 1, wherein

the radiation image detecting apparatus can select a driven state from two driven states of a battery-driven state in which the radiation image detecting apparatus is driven by obtaining the electric power from the battery and an external feeding-driven state in which the radiation image detecting apparatus is driven by receiving the electric power supplied from the outside through the cradle or the cable, and

the battery is charged in the external feeding-driven state.

5. The radiation image detecting system according to claim 1, wherein

the battery is a lithium ion capacitor.
