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.

A card feeding system that feeds cards from a stack to a conveyor system beneath product being carried. A card feed path arranged between a feed conveyor and the outfeed conveyor includes a fixed feed pinch roll and a pivot arm with a pivoting pinch roll and a pair of delivery rolls. A card stack receiving platform is located beneath a picker arm. An elevator is provided for raising the platform with the card stack. The picker arm has suction cups, and is pivotable from a card pick-up position to a feed position in which the card is positioned between the pivoting and fixed pinch rolls. A controller actuates the elevator, the picker arm, the pivot arm, the fixed and delivery pinch rolls to deliver single ones of the cards as product to be placed on the card transitions from the feed conveyor to the outfeed conveyor.

An image forming apparatus includes: a pair of rollers for conveying paper; a rocking mechanism for rocking the pair of rollers in a second direction orthogonal to a first direction, the first direction being a paper conveying direction; an upstream pair of rollers provided upstream of the pair of rollers in the paper conveying direction for conveying the paper; an upstream rocking mechanism corresponding to the upstream pair of rollers for rocking the upstream pair of rollers in the second direction; a first paper detector for detecting an end position of the paper in the second direction; and a controller controlling the rocking mechanism based on the paper end position to effect first rocking correction in which the pair of rollers is rocked, wherein the controller controls the upstream rocking mechanism to effect second rocking correction in which only the upstream pair of rollers is rocked.

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.

A paper sheet feeding unit includes: a plurality of feed rollers; a plurality of gate rollers respectively disposed opposite to the plurality of feed rollers in a one-to-one relationship; a biasing member that biases the plurality of gate rollers individually in a direction of the plurality of feed rollers; and a supporting member that supports the plurality of gate rollers and the biasing member.

A compacting machine for compaction a fabric including a feed roller, a retarding roller and a blade element configured to introduce the fabric to be treated between the feed roller and the retarding roller. The compacting machine also comprises a positioning device provided with at least one drive member configured to move one of the rollers with respect to the other of the rollers.

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.

The present invention is to provide a sheet stacking device for stacking sheets on which an image is formed, in which an initial operation time at the time the device is turned on is shortened, and, at the same time, the initial operation is simplified. This configuration enables reduction in operation noise and a prompt start at the time when the device is started.

A sheet conveying apparatus includes: a supply unit for supplying a sheet; a first switching unit disposed on a conveyance path of the sheet and configured to switch between a state of nipping the sheet supplied by the supply unit and a state of releasing the nipping of the sheet; a first tension applying unit disposed on one side of the first switching unit in a conveyance direction of the conveyance path and configured to apply tension to the sheet; and a detection unit disposed on the other side of the first switching unit in the conveyance direction of the conveyance path and configured to detect the tension of the sheet, wherein, in a state where the nipping of the sheet is released by the first switching unit, the first tension applying unit adjusts the tension of the sheet while the detection unit detects the tension of the sheet.

A sheet conveyance device includes a pair of separable contact rollers configured to convey a sheet, a contact/separation mechanism configured to support the pair of separable contact rollers in such a manner that the pair of separable contact rollers are able to come into separable contact with each other, and a solenoid configured to operate the contact/separation mechanism. The solenoid is driven so that the contact/separation mechanism causes the pair of separable contact rollers to come into pressure contact with each other, and driving of the solenoid is cancelled so that the contact/separation mechanism causes the pair of separable contact rollers to be separated from each other. Pulse width modulation duty control is performed on the solenoid while the pair of separable contact rollers are in pressure contact with each other when a plurality of the sheets are conveyed one by one at an interval.
