Patent ID: 7762547

Claim:
A bill processing apparatus, comprising: a skew correction mechanism, wherein the skew correction mechanism includes: base parts to be driven by a driving source toward a center of a bill traveling route through which a bill is conveyed; movable pieces which are supported at a fixed angle by the base parts in a movable manner toward a center of the bill traveling route and regulate side edges of the conveyed bill, the base parts being axially movable with respect to guide members extending in a direction perpendicular to the bill traveling route and inserted into through-holes formed in respective pairs of flanges of the base parts; and springs pushing the movable pieces toward the center of the bill traveling route, each of the springs being interposed between one of the respective pairs of flanges of the base parts and a flange of each of the movable pieces, wherein the base parts move against a pushing force of the springs when a reaction force of the bill is applied to the driving force as the base parts are driven toward the center of the bill traveling route such that the movable pieces hit side edges of the bill.
