Abstract
Abstract In a battery charging device, terminals for supplying a charging current to a battery to be charged are provided on one side wall of the device body, and a closure member is provided to be movable like a drawer. When the closure member is drawn out, at least one opening is defined between the closure member and said one side wall so that the battery can be inserted and held therein to be charged.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
182 words
A battery charging device adapted for charging a battery having a pair of connecting terminals provided on and exposed at the outer surface thereof, comprising: a drawer-like closure member provided to be movable between a first position where said closure member is disposed in close contact with or adjacent to one side wall of the device body wherein said closure member is retracted with respect to said body and said device is reduced in size, and a second position where the closure member is spaced apart from said one side wall, so that the device is enlarged in size, wherein when said closure member is made to assume said second position, at least one opening is defined between said closure member and said one side wall so that the battery can be inserted and held therein; and at least one pair of connecting terminals provided on said one side wall and adapted, when the battery is inserted and held in said opening, to be disposed in electrical contact with the connecting terminals of the battery so that the latter can be charged.
Claim 2
Dependent Claim
182 words
A battery charging device adapted for charging a battery having a pair of connecting terminals provided on and exposed at the outer surface thereof, comprising: a drawer-like closure member provided to be movable between a first position where said closure member is disposed in close contact with or adjacent to one side wall of the device body wherein said closure member is retracted with respect to said body and said device is reduced in size, and a second position where the closure member is spaced apart from said one side wall, so that the device is enlarged in size, wherein when said closure member is made to assume said second position, at least one opening is defined between said closure member and said one side wall so that the battery can be inserted and held therein; and at least one pair of connecting terminals provided on said one side wall and adapted, when the battery is inserted and held in said opening, to be disposed in electrical contact with the connecting terminals of the battery so that the latter can be charged.
Claim 3
Dependent Claim
37 words
A battery charging device according to claim 1, wherein said closure member is mounted on a bottom plate which can be drawn out of said device body at right angles with respect to said one side wall.
Claim 4
Dependent Claim
183 words
A battery charging device adapted for charging a battery having a pair of connecting terminals provided on and exposed at the outer surface thereof, comprising: a closure member provided to be movable between a first position where said closure member is disposed in close contact with or adjacent to one side wall of the device body, and a second position where the closure member is spaced apart from said one side wall, said closure member being mounted on two side plates which can be drawn out of the device body at right angles with respect to said one side wall, wherein when said closure member is made to assume said second position, at least one opening is defined between said closure member and said one side wall so that the battery can be inserted and held therein; and at least one pair of connecting terminals provided on said one side wall and adapted, when the battery is inserted and held in said opening, to be disposed in electrical contact with the connecting terminals of the battery so that the latter can be charged.
