PURPOSE:To simplify the operation of fitting a DC power supply device into a charging-type electric apparatus and improve the convenience in using the apparatus by making a plug blade sink into the plug installation part of the DC power supply device during the time when the device is attached to the apparatus and making the plug blade protrude during the time when the device is detached from the apparatus. CONSTITUTION:When a charged DC power supply device 5 is attached to a charging-type electric apparatus, a plug blade 12 which protrudes above a top plate 14 is fixed by the connection between a connection part 13a and a connection groove 19b. When the device 5 is inserted into an installation space 1a, a plug handle 13 is pushed inward by the projection 3a of a current feeding metallic member 4 to disconnect the part 13a from groove 19b enabling the plug handle 13 to vertically move in a guide groove 19a. As a result, the plug blade 12 gradually sinks into a plug installation part 18 and is finally completely installed in the part 18. When the device 5 is further pushed into the space 1a, the plug handle 13 pushes a bottom plate 6 into the lower end of the housing 1 of the electric apparatus. |
