BATTERY PACK LOADING/UNLOADING MECHANISM

PURPOSE:To reduce the size and the weight of a battery pack loading/unloading mechanism by providing a rotary lever, a latch spring and a latch member at the side of an equipment main body and providing a latch groove part at the side of a battery pack. CONSTITUTION:When a battery pack 2 is attached to a battery pack loading part 11 of an equipment main body 1, a projection part 51, of a latch member 5 is pushed into the main body 1 through an equipment main body loading part 21. Then the member 5 revolves. When the pack 2 is completely loaded in the part 11, the part 51 is energized toward E by a latch spring 4 and fitted into a latch groove part 23 of the part 21. Thus the pack 2 is fixed. When the pack 2 is unloaded, a rotary lever 3 is turned against the force of the spring 4. Thus the part 51 is released out of the part 23. Then the pack 2 is slided in the side direction and then removed out of the main body 1. In such a constitution, the number of parts can be decreased and the attachment space can be reduced for a bettery pack loading/unloading mechanism.
