PURPOSE:To enable a necessary number of batteries to be connected beforehand or an additional battery to be installed during use without enlarging the space for batteries, and enable an electronic apparatus to be used continuously for a long period of time by providing a battery case with a means of electrically connecting the battery case to either the power source terminal of the electronic apparatus or the electrode of another battery case, and a means of mechanically connecting the battery case to either said electronic apparatus or another battery case. CONSTITUTION:A pack 41 is mechanically and electrically connected to a VTR1 by screwing the screw thread 9 of a bolt 6 into a screw hole 2. Since the flanged part 6a of the bolt 6 touches an electrode 10 with pressure, the voltage of a battery is supplied to the VTR1 from the electrode 10. On the other hand, a pack 42 is mechanically and electrically connected to the pack 41 by screwing the screw thread 9 of a bolt 6 into the screw hole 8 of the bolt 6 of the pack 41. Here, since the flanged part 6a of the screw 6 of the pack 42 touches an electrode 10 with pressure, the battery voltage of the pack 42 is supplied from the electrode 10 to the VTR1. The battery of the pack 41 and the battery of the pack 42 are connected parallel to one another. An additional pack 4 can be connected to the pack 42. |
