A displacement amount calculation part in a base material processing apparatus calculates the degree of matching between an upstream data section and a downstream data section included in a first and a second detection results, which indicate time-varying changes in the positions of an edge of a base material in the width direction at an upstream and a downstream detection positions. This calculation uses calculation results obtained by sequentially calculating the degrees of matching between sub-data sections in the upstream data section and downstream sub-data sections in the downstream data section. This reduces the amount of computation and enables highly accurate detection of the amount of displacement of the base material in the transport direction on the basis of an identification result of the downstream data section that is highly matched with the upstream data section.

An apparatus for splicing comprises a first web support surface configured to support a traveling web thereon and a second web support surface configured to support a replacement web thereon. The first traveling web travels in a machine direction. The splicing assembly also comprises a first web sensor and a web joiner. A controller is configured to determine, via the first web sensor, a position of a trailing end of the traveling web and to, in response to determining the position of the trailing end, cause a leading end of the replacement web to be positioned adjacently to the trailing end. The computer is also configured to control the web joiner to create a joint coupling the trailing end to the leading end.

A displacement amount calculation part in a base material processing apparatus calculates the degree of matching between an upstream data section and a downstream data section included in an upstream and a downstream detection results, which indicate time-varying changes in the positions of an edge of the base material in the width direction at an upstream and a downstream detection positions. This calculation uses the results of comparison between signals in a predetermined frequency band extracted from the upstream detection result and signals in the predetermined frequency band extracted from the downstream detection result. Accordingly, a downstream data section that is highly matched with the upstream data section can be identified with high accuracy, and the amount of displacement of the base material in the transport direction can be detected with high accuracy on the basis of an identification result.

An image forming device including an optical sensor, an ultrasound sensor, and a conveyance guide. The optical sensor and the ultrasound sensor are disposed alongside a conveyance path of a sheet and are used to determine sheet type. The conveyance guide guides the sheet along the conveyance path. The conveyance guide is structured such that, on the conveyance path between the optical sensor and the ultrasound sensor, the sheet is in contact with the conveyance guide while a portion of the sheet is in a light irradiation range of the optical sensor and a different portion of the sheet is in an ultrasound irradiation range of the ultrasound sensor.

Provided is a recording medium detection device which prevents the decline in productivity. The recording medium detection device comprises a first detecting section and a second detecting section. The first detecting section performs a first adjustment process and makes a detection of a recording medium being transported. The second detecting section is located more downstream than the first detecting section in the transportation direction of the recording medium, performs a second adjustment process which takes a longer time than the first adjustment process, and makes a detection of the recording medium being transported.

A sheet feeder includes a sheet tray, a feed roller, a sheet feed frame, a contact element, a guide frame, a photosensor, a shield, and a linkage. The feed roller feeds a sheet on the sheet tray. The sheet feed frame holds the feed roller. The contact element is pivotable relative to the sheet feed frame. The guide frame is disposed below the sheet feed frame. The photosensor includes a light emitter and a light receiver. The shield is movable between a light transmission position and a light shield position. The linkage connects the contact element and the shield such that the shield is movable as the contact element pivots. The light receiver receives the light emitted from the light emitter when the shield is at the light transmission position. The shield at the light shield position shields the light receiver from the light emitted from the light emitter.

A post-processing apparatus includes a movable portion and an opposing portion that are arranged to be opposite to each other with a conveyance path through which a sheet is conveyed interposed between the movable portion and the opposing portion, and a restricting member that has a holding surface including an abutment surface against which a sheet abuts, is capable of changing a posture between a first posture in which the holding surface closes the conveyance path and a second posture in which a clearance is formed in at least part of the conveyance path and is attached to a side where the opposing portion is located with respect to the conveyance path, wherein the movable portion processes a sheet positioned at the abutment surface by the restricting member having the first posture by moving toward the opposing portion.

A sensing apparatus can be configured to detect an edge of a paper that is received by an automated transaction machine (ATM). The paper can move along a path located inside the ATM, the path having opposite first and second sides. The sensing apparatus can include a light emitter and a light detector on the first side of the path, with the light emitter positioned so that it can emit light across the path to the second side. The light detector can be configured to detect light from the light emitter and can emit a signal corresponding to an amount of detected light. The sensing apparatus can also include a control circuit that can control a flow of power to the light emitter, and the control circuit can also receive the signal emitted by the sensor.

In a medium conveying device, a projector projects light, a projection light amount of the light changes, at every fixed time, to a first projection light amount and a second projection light amount less than the first projection light amount, a receiver receives the light projected from the projector, a processor determines, at fixed sampling timings, whether a reception light amount of the receiver is at a first reception light level or a second reception light level smaller than the first reception light level, determines, when the reception light amount alternately changes to the first reception light level and the second reception light level, that a medium is not present on a conveying path, and determines, when the reception light amount is fixed to either the first reception light level or the second reception light level, that the medium is present on the conveying path.
