Abstract

A recording apparatus has a battery as a driving power source of the recording apparatus, a holding portion for holding the battery, and a connecting device for electrically connecting the recording apparatus and the battery to each other when the battery is held in the holding portion. A biasing device biases the battery on a side opposed to a mounting direction of the battery when the battery is held in the holding portion, and a fixing device fixes the battery held in the holding portion against the biasing force of the biasing device.
