Medium intake device

摘要

A lower pressure plate (43) is disposed upon a paper currency pressing part (34) of a paper currency intake part (5) below an upper pressure plate (41) with a spring (44) interposed therebetween, and the paper currency pressing part (34) presses the lower pressure plate (43) upon stacked paper currency (BLC). Thus, when the stacked paper currency (BLC) oscillates vertically with the rotation of a picker roller (23), the paper currency pressing part (34) absorbs by the spring (44) an upward force which is applied from the stacked paper currency (BLC). Furthermore, the paper currency pressing part (34) presses the lower pressure plate (43) by a restoring force of the spring (44) with respect to the falling stacked paper currency (BLC). Accordingly, the paper currency pressing part (34) continues to make the lower pressure plate (43) make contact with the uppermost part of the stacked paper currency (BLC), allowing the intake of the paper currency (BL) to continue without misalignment of the paper currency in the stacked paper currency (BLC) to occur.

主权项

1. A media feeding device comprising:
a floor guide on which paper sheet-like media are stacked and placed into a stack, and which is inclined in such a way that a feed direction side thereof, that feeds the media in the lowermost portion of the stack, is lower than another side of the floor guide; rollers, each of which has a roller base portion formed in a substantially cylindrical shape and a picker portion that is disposed on part of a peripheral side surface of the roller base portion and causes frictional force to act on the media, with the rollers rotating in such a way that the picker portions project toward the stacked media from a lower side of picker holes formed in the floor guide; a mask guide that supports the stacked media on the feed direction side of the floor guide; a pressing member that has a predetermined mass and utilizes the force of gravity to press the stacked media against the floor guide; an auxiliary pressing member that is interposed between the pressing member and the stacked media; absorbing members that absorb force applied to the auxiliary pressing member from the media; regulating bodies disposed at left and right side edges of the pressing member at positions near a front of the pressing member and near a rear of the pressing member; and regulated bodies that extend upward and are disposed on the auxiliary pressing member at left and right side edges of the auxiliary pressing member near a front of the auxiliary pressing member and a rear of the auxiliary pressing member, each of the regulated bodies having a hole portion formed in a center of the regulated body, the regulating bodies being disposed in the hole portions, the media feeding device being configured to be able to move the auxiliary pressing member in upward and downward directions relative to the pressing member, to rotate the auxiliary pressing member in rightward and leftward directions, or to rotate the auxiliary pressing member in frontward and rearward directions.
