Abstract
An automatic locking apparatus for a movable module in a device uses device's weight and position to lock the movable module. It includes an input unit located on a bottom wall of the device to detect if the device is positioned on a support plane under a normal state, a transfer unit for receiving input from the input unit to generate a response, and an output unit for receiving the response to actuate a lock or unlock action on the movable module. When the input unit detects the device being properly positioned on the support plane, the transfer unit will be triggered to make the output unit disengaged with the movable module for normal operation. When the input unit detects the device being removed from the support plane at an abnormal state, the transfer unit will be triggered to make the output unit locking the movable module inside the device at a selected location.
