Abstract

A paper sheet separation transport device and a paper sheet handling device designed for improved paper jam processing work and other internal maintenance. A feed roller, frictional separating member, drawing transport part that draws out one separated paper sheet, and an axis support part supports at least a set-out roller and the feed roller about an axis to be rotationally movable between a processing enable position and a processing disable position, and the feed roller is at a position adjacent to the drawing transport part when the set-out roller and the feed roller are at the processing enable position, and the feed roller is separated away from the drawing transport part when the set-out roller and the feed roller are retracted to the processing disable position.

First claim

What is claimed is:

1 . A paper sheet separation transport device comprising:
a first module in which a paper sheet reception processing unit is fixed to a paper sheet storage processing unit, a downstream module removably coupled to the first module, and a controller that controls various control targets; wherein the paper sheet reception processing unit includes a frame including an opening on a front surface to receive paper sheets, a paper feed tray removably attached to the frame, a set-out roller that sets out paper sheets from a paper sheet bundle on the paper feed tray, a feed roller and a frictional separating member including a separating part that separates paper sheets set out by the set-out roller in a multi-fed state into one sheet, a drawing transport part that draws out one paper sheet separated by the separating part to send the paper sheet downstream, and an axis support part that supports at least the set-out roller and the feed roller on the frame about an axis pivotable between a processing enable position and a processing disable position; and wherein the feed roller is at a position adjacent to the drawing transport part when the set-out roller and the feed roller are at the processing enable position, and the feed roller is separated away from the drawing transport part when the set-out roller and the feed roller are at the processing disable position.

2 . The paper sheet separation transport device according to claim 1 , wherein:
the paper sheet reception processing unit includes a first transport mechanism that transports a paper sheet having been sent from the drawing transport part toward the paper sheet storage processing unit, and a second transport mechanism that performs return transport to a return paper sheet accumulating part that receives paper sheets having been reversely sent from the paper sheet storage processing unit; the axis support part includes a first axis support part that supports a first movable base about an axis to be rotationally movable with respect to the frame, and a second axis support part that supports a second movable base about an axis to be rotationally movable with respect to the first movable base; at least one or more components forming the second transport mechanism are mounted on the first movable base; and at least the set-out roller and the feed roller of the first transport mechanism are mounted on the second movable base.

3 . The paper sheet separation transport device according to claim 2 , further comprising:
a latch mechanism that causes the set-out roller and the feed roller to be caught at the processing enable position in an initial state and that cancels the catch to allow the set-out roller and the feed roller to rotationally move to the processing disable position when a cancelling operation is performed; and wherein the latch mechanism comprises a first cancel mechanism that enables a canceling operation from front only in a state where the paper feed tray is removed from the paper sheet reception processing unit, and a second cancel mechanism that enables a cancelling operation from a direction other than the front in a state where the paper feed tray is attached to the paper sheet reception processing unit.

4 . The paper sheet separation transport device according to claim 3 , wherein:
the latch mechanism comprises a latch member that is provided on the second movable base to be capable of advancing or retracting and that is caught on or released from a fixed-side catch part provided at a fixed part, an elastic member that biases the latch member in a direction to be caught on the fixed-side catch part, a first cancel operation part that is provided on the latch member and that moves the latch member in a direction to be released from the fixed-side catch part by an operation from front, and a second cancel operation part that is provided on the fixed part to be capable of advancing and retracting and that moves the latch member in a direction to be released from the fixed-side catch part by an operation in a direction different from the front, and the latch mechanism keeps a state where the latch member is caught on the fixed-side catch part when the set-out roller and the feed roller supported by the second movable base are at the processing enable position, and allows the set-out roller and the feed roller to move to the processing disable position when a cancelling operation is performed to the first cancel operation part or the second cancel operation part.

5 . The paper sheet separation transport device according to claim 1 further comprising:
a lock mechanism that removably couples the first module to the downstream module, wherein
the lock mechanism includes a release operation piece that is supported by a fixed part of the paper sheet reception processing unit to be capable of advancing and retracting in a front-back direction, an operated piece that is supported about an axis by a shaft, which is provided on a fixed part of the paper sheet storage processing unit, to be rotationally movable and that is operated by the release operation piece to rotationally move, and a lock piece that is supported about an axis by a shaft, which is provided at a fixed part of the paper sheet storage processing unit, to be rotationally movable and that rotationally moves between a locked attitude where the lock piece is caught on a fixed part of the downstream module and an unlocked attitude where the catch is canceled; and
the operated piece actuates the lock piece in a direction of unlock by pushing backward of the release operation piece or pulling frontward thereof.

6 . A paper sheet handling device comprising the paper sheet separation transport device according to claim 1 .

7 . A paper sheet handling device comprising the paper sheet separation transport device according to claim 2 .

8 . A paper sheet handling device comprising the paper sheet separation transport device according to claim 3 .

9 . A paper sheet handling device comprising the paper sheet separation transport device according to claim 4 .

10 . A paper sheet handling device comprising the paper sheet separation transport device according to claim 5 .

11 . A paper sheet separation transport device comprising:
a first module in which a paper sheet reception processing unit is fixed to a paper sheet storage processing unit, a downstream module removably coupled to the first module, and a controller that controls various control targets; wherein the paper sheet reception processing unit includes a frame including an opening on a front surface to receive paper sheets, a paper feed tray removably attached to the front surface of the frame, a set-out roller that sets out paper sheets from a paper sheet bundle on the paper feed tray, a feed roller and a frictional separating member comprising a separating part that separates paper sheets set out by the set-out roller in a multi-fed state into one sheet, a drawing transport part that draws out one paper sheet separated by the separating part to send the paper sheet downstream, and an axis support part that supports at least the set-out roller and the feed roller on the frame about an axis to be pivotable between a processing enable position where paper sheet transport processing is enabled and a processing disable position where paper sheet transport processing is disabled, and wherein the feed roller is at a position adjacent to the drawing transport part when the set-out roller and the feed roller are at the processing enable position, and the feed roller is separated away from the drawing transport part when the set-out roller and the feed roller are retracted to the processing disab
