A paper aligning mechanism and an image generating device having the same are provided, the paper aligning mechanism is arranged on a calibration path of the image generating device, the calibration path is arranged between a paper assigning mechanism and a paper-feeding mechanism of the image generating device, and the paper aligning mechanism has at least two calibrating swingarms arranged spacedly. Each of the calibrating swingarms has an arm portion and a pivoting axle portion arranged on the arm portion to pivotally connect the arm portion to the image generating device. The arm portion has an extending segment and a limiting segment extended from the extending segment, the limiting segment is downward extended along the calibration path toward an exit of the calibration path to be swingable and to block the exit of the calibration path.

There is provided a feed apparatus including a support unit, a feed roller, a swingable arm to support the feed roller, a guide unit, a movable member movable to a retracted position and a protruding position at which the movable member can abut against the sheet supported by the support unit, a driving source, driving transmission units; and a contact-separating mechanism to move the feed roller to a separated position and an abutment position at which the feed roller abuts against the sheet supported by the support unit. In a state in which the movable member is the protruding position and the feed roller is the separated position, a time required to start feeding of the sheet by the feed roller moved from the separated position to the abutment position is longer than a time required to shift the movable member from the protruding position to the retracted position.

A document sheet conveyance device includes an inner guide and an outer guide defining a curved sheet conveyance passage for allowing conveyance of a document sheet from a document sheet feeding section to a predetermined document reading position, and a movable guide projectable into the sheet conveyance passage. The outer guide includes an outer curved guide surface defining an outer surface of the sheet conveyance passage. The inner guide includes an inner curved guide surface defining an inner surface of the sheet conveyance passage, and a first flat part. The movable guide includes a projecting portion projectable into the sheet conveyance passage, and a second flat part provided in the projecting portion. The movable guide is attached to the outer guide in such a way as to allow the first and second flat parts to face each other with the projecting portion projecting in the sheet conveyance passage.

A slider moving in a sliding direction between first and second positions shifts a second path-defining member, relative to a first path-defining member, between first and second states. A pair of movable members each disposed on a corresponding side of a slider in a width direction is movable individually in the sliding direction to shift between third and fourth states. The movable members, when both in the third state, position the slider to the first position and, when both in the fourth state, position the slider to the second position. Each movable member supports a corresponding widthwise end of the slider immovably in the sliding direction and movably in the width direction. A support frame supporting the second path-defining member supports a widthwise central portion of the slider movably in the sliding direction and rotatably on a plane parallel to the sliding direction and the width direction.

The sheet conveyance apparatus includes a frame supporting first and second bearing portions, and a restricting portion. The frame supports the first and second bearing portions such that a movable amount with respect to the frame, in a direction along a sheet conveying direction, of the first bearing portion is larger than that of the second bearing portion. The restricting portion is provided with a predetermined gap from the first bearing portion in the direction along the sheet conveying direction, and configured to restrict the first bearing portion from moving in the direction along the sheet conveying direction in a case when the first bearing portion abuts with the restricting portion.

A sheet conveying apparatus includes: a first pair of conveying rollers for conveying a sheet; a second pair of conveying rollers against which the leading edge of the sheet conveyed by the first pair of conveying rollers is hit and which conveys the sheet together with the first pair of conveying rollers by rotating after a loop is formed on the sheet; a separating portion for separating the first pair of conveying rollers; a first conveyance path for guiding the sheet; a second conveyance path which is a path different from the first conveyance path and guides the sheet; and a controller which changes a separation timing at which the first pair of conveying rollers is separated after the loop is formed on the sheet, depending on whether the sheet is guided by the first conveyance path or by the second conveyance path.

A conveyor includes: a supporting member which supports the first and second roller units to allow the first and second rollers to take one of a first conveyance position and a first retracted position; a movable member which is movable between a first position where the first roller and the second roller take the first conveyance position and a second position where the rollers take the first retracted position; a cover member which is switchable between a closed state where the cover member is a part of the conveyance passage and an open state where a part of the conveyance passage is open; and an interlocking mechanism which is configured to move the movable member to the second position when the cover member is in the open state and moves the movable member to the first position when the cover member is in the closed state.

Provided is a paper sheet processing apparatus capable of distinguishing a counterfeit bill or a paper sheet suspicious to be a counterfeit bill from bills inserted through an insertion slot to stop a wrongdoing. A storage unit stores information on a paper sheet read by a bill reader and a verification unit verifies the paper sheet using the information on the paper sheet stored in the storage unit. If the paper sheet is determined to be counterfeit in the verification, a conveyance unit conveys the paper sheet toward the insertion slot. A comparison unit compares the image data of the inserted paper sheet with image data of a previously inserted paper sheet and if the image data of the inserted paper sheet is determined to be identical to the image data of the previously inserted paper sheet in the comparison, a control unit sends a signal to a host apparatus.

Provided is a paper sheet processing system capable of collecting a wrong paper sheet put in a bill processing apparatus to examine the collected paper sheet without making the supplier feel doubt. A paper sheet processing apparatus verifies a paper sheet using image data acquired by a bill reader when the bill is being conveyed. If the paper sheet is determined to be counterfeit in the verification, the paper sheet processing apparatus holds the paper sheet within the paper sheet processing apparatus and sends a signal from a controller of the paper sheet processing apparatus to instruct a report device to report a result different from the result of the verification. The report device reports a result irrelevant to use of a wrong paper sheet.

Provided is a paper sheet processing system capable of preventing a large number of wrong paper bills put in a paper sheet processing apparatus at one time from being exchanged with clean money. A bill processing apparatus sends information on a total amount of the bills supplied to the bill processing apparatus incorporated in a gaming machine and the number of games played by a player counted by a counter to a management server. The management server compares the total amount with a predetermined amount and if the total amount is higher than the predetermined amount, compares the counted number of games with a predetermined number. If the counted number of games is smaller than the predetermined number, the management server sends a report signal to a management apparatus.
