Abstract

A paper transporting apparatus includes a pair of transport rollers including a first transport roller (6), a second transport roller (7), a first roller shaft (951) inserted through the first transport roller (6), a second roller shaft (952) inserted through the second roller (7), an urging member (97) which urges the second roller shaft (952) towards the first roller shaft (951), and a cover member (5) arranged to be opened and closed. The urging member (97) is attached to the inner face of the cover member (5) to support the second roller shaft (952), and urge the second roller shaft when the cover member (5) is closed.
