? A protrusion 10'-1 on the hook 10' projects beyond the hole 11-2 and presses a portion of the movable short-circuit contact 5' as shown in Figure #g5 (b). As a result, the movable short-circuit contact 5' is fixed at the fixed part t.
Since it bends around i-i as a fulcrum and its contact portion 5'-1 contacts the short-circuit contact portion 6', a short circuit between the resistance element 3 and the (+) contact 7' is performed, and the N1cdt4tsuku10 as described above is established.
' becomes available. Furthermore, when the N1cd pack 10' is removed from the battery compartment 12, the suppression by the projections 10'-1K is released, and the movable short-circuiting contact 5' returns to its original state with its elasticity, thereby canceling the above-mentioned short circuit. In addition, when the N1cd power supply unit 10' is not in use, it can be powered by dry batteries 8 and an AC adapter in the same way as the conventional power supply unit described above.
It goes without saying that you can use the power supply.
