PURPOSE: An apparatus for exchanging a backup battery for a communication station terminal is provided to decrease the number of process for an exchanging work and minimize human/material damage generated in the exchange work process by automating a work process for inserting and ejecting the backup battery in a backup battery chamber. CONSTITUTION: A spiral flute(11) is formed at an internal one side of a battery chamber(120) along an external circumference surface, and a cylindrical axis(10) in which a driven gear(12) is installed is vertically installed along a lower side. A driving gear(21) combined with the driven gear(12) is installed at one-side wall of the battery chamber(120) along one end, and a rotation axis(20) in which a knob(22) is installed is horizontally installed along the other end. A backup battery(100) is safely received in an external circumference surface of the cylindrical axis(10), and a vertical moving board(30) is spirally combined in a horizontal direction to be risen along the spiral flute(11). |
