PURPOSE:To simplify attachment and detachment of a storage battery by causing a socket, in which the battery is installed, to be freely installed and ejected. CONSTITUTION:A storage-battery attaching device 100 is constituted of storage battery socket bases 9 and 10 made of a synthetic resin. When the socket base 10 is slid in counter-A direction and A direction, respectively, connection terminals 9c and 10c are connected to and severed from a control circuit 11, and a storage battery 12 is connected to and severed from the control circuit 11. By thus fitting the storage battery 12 in the storage battery socket so as to enable the socket to be attached and detached from the front side of an electric measuring instrument, the battery 12 can be installed, ejected and exchanged without using any special tools and parts. |
