Bill processing apparatus
View Patent ↗A bill processing apparatus comprising: movable pieces that are movable toward a center of a bill traveling route through which a bill is conveyed by a driving source, and regulate side edges of the bill to be conveyed so as to make the bill aligned in parallel with a conveyance direction, and a control device that controls driving of the driving source is provided. Here, the control means drives the driving source to move the movable pieces toward the center of the bill traveling route from a position at which the movable pieces touch the side edges of the bill after the bill passes the movable pieces.
1. 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.
2. The bill processing apparatus according to claim 1 , wherein
the movable pieces comprise regulation walls to contact side edges of the conveyed bill, and
the movable pieces are driven by the driving source via a pinion positioned between the guide members and racks formed on the base parts.
3. The bill processing apparatus according to claim 2 , wherein an upward projection is disposed on a top end of at least one of the regulation walls.
