The lock arm 50 is attached to a moving mechanism 68 shown in FIG. 7, for example, and is housed so as to be movable in a direction parallel to the connection terminals 15B1 to 15B3 (direction of the arrow P2). That is, an operation portion 66 is provided at a corner portion of the casing 16, and when the operation portion 66 is pushed in the direction in which the operation portion 66 is pushed (the direction of the arrow P1), the L-shaped member 70 rotates around the fulcrum 71 (rotation direction R1). ). Since the end portion of the L-shaped member 70 is joined to the rotation node a1, the end portion of the L-shaped member 70 moves the rotation node a1 in the direction of the arrow P3. Since the rotation node a2 is attached to the housing 16 and does not move, the rotation node a3 is moved in the direction of the arrow P2. A lock arm 50 is attached to the rotation node a3.
As a result, the lock arm 50 moves in the direction of the arrow P2. A spring 69 is provided between the rotation node a2 and the rotation node a3. When the hand is released from the operation unit 66, the lock arm 50 returns to the position before the movement.

That is, it is possible to prevent a third party from taking away the electronic cassette 12 from the storage location during storage.

  When releasing the lock function, a wireless communication function with the console 64 is used. That is, the solenoid 56 is controlled from the console 64, the pin 58 is moved, and is extracted from the through hole 54. Thereafter, the operation unit is pushed in the direction of the arrow P1, and the lock arm 50 is moved in the direction of the arrow P2. Thereby, the nail | claw part 52 remove | deviates from the nail | claw receiving part 80S. In this state, the lock connector 15 may be extracted from the electronic cassette 12.

The cut-out portion 92 is used. The following description will focus on the differences.

As shown in FIG. 12A, the lock connector 94 according to the second embodiment is formed by providing a notch 92 at an end 94S on the connection part 23 side. That is, since the notch 92 has an open end on the connecting portion 23 side, when the lock connector 94 is connected to the electronic cassette 12, the open end is closed by the side wall 94 </ b> S of the electronic cassette 12. The connecting hole is formed.
The connection method and locking method between the lock connector 94 and the electronic cassette 12 are the same as those in the first embodiment, and a description thereof will be omitted.

As shown in FIG. 12B, the electronic cassette 12 is connected with a wire 86 in a state where the lock connector 94 is locked. Alternatively, the lock connector 94 is attached to the electronic cassette 12 with the wire 86 attached.
One end of the wire 86 is attached using the notch 92 of the lock connector 94, and the other end is attached to the fixing portion 88.

As a result, the lock connector 94 is connected to the fixing portion 88, and the portable range of the electronic cassette 12 is limited to the length of the wire 86. That is, it is possible to prevent a third party from taking away the electronic cassette 12 during storage.
In addition, the notch part 92 can be used as a strong attachment part by forming near the center of the lock connector 94.
