Abstract
A power supply device in which a device shaft provided with a power receiver is inserted in a through-hole of a port site, which is capable of supplying electric power to the power receiver at a low cost and enabling fine operation of the device shaft. The power supply includes a port site; first terminals provided on an inner surface of the through-hole; wires that connect the first terminals and a power source; a device shaft that is insertable into the through-hole; a power receiver provided on the device shaft; second terminals provided on an outer surface of the device shaft; and wires that connect the power receiver and the second terminals. Electric power from the power supply can be supplied to the power receiver by inserting the device shaft into the through-hole to thereby bring the first terminals and the second terminals into contact with each other.
