Paper stock processing device

A paper stock processing device, comprising:

• a storage unit having a storage space in which paper stock is layered and stored;
• a conveyance mechanism for conveying paper stock to the storage unit;
• a movable piece extending in a direction perpendicular to a conveyance direction in which paper stock is conveyed by the conveyance mechanism, the movable piece being configured to emerge and sink with respect to the storage space;
• a hole formed on a wall part of the storage unit, in which hole the movable piece emerges and sinks;
• a guide piece facing the movable piece, which moves integrally with the movable piece;
• a drive source for causing emerging and sinking operation of the movable piece;
• and
• a control unit configured to control the drive source,
• wherein the paper stock processing device is configured such that after conveyance of paper stock to the storage unit by the conveyance mechanism stops in a position where a trailing end part of paper stock faces the movable piece, the movable piece is caused to emerge and sink in the hole so that the rear end part of the paper stock, which is in the position to face the movable piece, is moved toward the storage space, thereby layering and storing the paper stock in the storage space,
• wherein the movable piece, while being positioned on a side of the storage space of the storage unit, forms an import space through which paper stock being conveyed by the conveyance mechanism passes on its way to the storage space;
• and
• wherein the control unit is configured to control the drive source so that the movable piece is moved toward the storage space to close the hole with the guide piece, and after conveyance of paper stock to the storage unit by the conveyance mechanism stops in the position where the trailing end part of the paper stock faces the movable piece, an emerging/sinking operation is executed in which operation the movable piece is moved in a direction from the storage space toward an import space so that the movable piece enters a sunk state with respect to the hole and then the movable piece in the sunk state is moved back toward the storage space.

A paper stock processing device, comprising:

• a storage unit having a storage space in which paper stock is layered and stored;
• a conveyance mechanism for conveying paper stock to the storage unit;
• a movable piece extending in a direction perpendicular to a conveyance direction in which paper stock is conveyed by the conveyance mechanism, the movable piece being configured to emerge and sink with respect to the storage space;
• and
• an insertion slot through which the paper stock is inserted into the paper stock processing device,
• wherein the paper stock processing device is configured such that after conveyance of paper stock to the storage unit by the conveyance mechanism stops in a position where a trailing end part of paper stock faces the movable piece, the movable piece is caused to emerge and sink so that the rear end part of the paper stock, which is in the position to face the movable piece, is moved toward the storage space, thereby layering and storing the paper stock in the storage space,
• wherein the storage unit is disposed in a position to face the movable piece and includes a pressing plate configured to pinch the layered and stored paper stock between the movable piece and the pressing plate, and
• the pressing plate has, at a surface in contact with the layered and stored paper stock, a first regulating member whose friction force is larger when the paper stock moves toward the storage unit than when the paper stock moves toward the insertion slot.

A paper stock processing device, comprising:

• a storage unit having a storage space that is sized and configured to receive and store therein, in a layered manner, paper stock having a predetermined length;
• a conveyance mechanism that is configured to transport paper stock along a conveyance surface in a conveyance direction and to the storage unit;
• a first slot formed in the conveyance surface and extending transverse to the conveyance direction;
• a stacking member extending generally parallel to the first slot, which stacking member is supported and positioned so as to reciprocate translationally into and out of the first slot;
• and
• a pressing member extending generally parallel to the stacking member and being disposed on an opposite side of the stacking member than the first slot;
• wherein the paper stock processing device is configured such that paper stock comes to rest in the storage unit, at the end of a conveying-in process, with a trailing end of the paper stock located in the vicinity of the first slot;
• and
• wherein the stacking member is configured such that as it reciprocates into the first slot, it presses against a first surface of the paper stock near the trailing end thereof and causes the trailing end of the paper stock to be deflected in the direction of travel of the stacking member, and the stacking member moves to an opposite side of the paper stock as it travels farther into the first slot and the trailing end of the paper stock returns to a non-deflected position;
• and
• wherein the stacking member is configured such that as it reciprocates out of the first slot, it presses against a second surface of the paper stock, on said opposite side of the paper stock and near the trailing end thereof, so as to press the trailing end of the paper stock toward the pressing member.
