A locking mechanism that provides fast and easy locking and unlocking of a battery in a wireless detector is disclosed. The locking mechanism prevents battery from falling out of detector housing when a user forgets to lock the battery manually. The locking of battery is accomplished by pressing the battery into a back cover of the detector. A left lock automatically switches to lock position due to a spring mechanism on the left lock. The easy unlocking of battery requires only one spring lock which is handled by one hand to hold the unlock position, and the other hand is free to pick up the battery at the same time.

The present invention relates generally to a wireless detector employed in a radiographic imaging system, and more particularly, to a lock mechanism for locking battery of the wireless detector.

A radiation detector may be a stationary detector or a portable or cassette type detector. The stationary detector is generally installed as a part of a radiographic imaging system at a predetermined position, whereas the portable detector is freely carried to a desired location. Both stationary and cassette type radiation detectors generally have a built-in battery when driven as independent detector. The battery is required to be locked and fixed in the detector to prevent the battery from loosening due to vibration and shock.

A conventional lock mechanism includes a nail-like member which is driven by an actuator, such as, a solenoid.  The nail-like member is movable between a state projecting into an opening and a state retracting inside housing. The lock mechanism projects into the opening when the actuator is energized, and is retracted inside the housing when the actuator is released from an operation. When a battery is accommodated inside the housing and the lock mechanism projects, the battery is locked in a state in which the battery is not removable. When the lock mechanism is retracted, the battery is released from a locked state and becomes removable.

Another conventional lock mechanism includes a button for releasing the battery. The mechanism requires a small stick to touch the lock which is tiny and hidden deep as depicted in Figure 1.

One other conventional lock mechanism includes two buttons for releasing battery of the detector. However, the mechanism requires both hands for operating the mechanism. Figure 2 depicts the above mentioned lock mechanism having two buttons.

It would be desirable to have a lock mechanism that does not require manual locking of the battery.
