  • Patent number: 4792650
    Abstract: A module mounting system for an electronic device capable of mounting a pair of electronic components each including a locking groove. The mounting system includes an operation switch having an engaging member to be engaged with the locking groove in each of the electronic components mounted on the electronic device. The operation switch provides a locking position to make the engaging member fit in the locking grooves simultaneously and a plurality of unlocking positions for unlocking one of the components selectively. The operation switch shuts off power supply to the electronic device when set at any of the unlocking positions, or supplies power to the electronic device when set at the locking position.
