A transport apparatus includes a speaker and a mike disposed at respective positions between which a transport path of a medium is interposed, where the speaker and the mike face each other, a drive circuit that outputs a drive signal to the speaker, an amplifier circuit formed by coupling a plurality of amplifiers in series, where the amplifier circuit amplifies and outputs an output signal of the mike, a processor to which the output signal of the amplifier circuit is input, an attenuation circuit disposed in a stage preceding a predetermined amplifier, where the attenuation circuit attenuates an input signal and outputs the input signal to the predetermined amplifier, and a switch that switches an attenuation factor by the attenuation circuit.

A method, apparatus and program product may utilize packaging material quality compensation to sense changes in certain characteristics of a packaging material that can be associated with increased risks of film breaks, and automatically make certain changes in machine settings to mitigate the impact of those enhanced risks.

A medium conveying apparatus includes a floating sensor located on an upstream side of a first roller in the medium conveying direction to detect a floating of the medium placed on a medium tray, a skew sensor located on a downstream side of a second roller in the medium conveying direction to detect a skew of the medium conveyed by the second roller, and a processor to determine whether the floating of the medium has occurred based on an output signal from the floating sensor, determine whether the skew of the medium has occurred based on an output signal from the skew sensor, and determine that a conveyance abnormality of the medium has occurred when the processor determines that the floating of the medium has occurred and the processor determines that the skew of the medium has occurred.

A processing system includes a stacker on which at least one medium recorded with an image is stacked, a holding unit configured to hold the medium, a processing path extending from the stacker to the holding unit, a pick roller configured to transport the medium from the stacker to the processing path, a reading unit configured to read the medium transported through the processing path, and a control unit configured to store indication data indicating an index of whether to transport a medium to the holding unit, wherein, when receiving a processing instruction from a user, the control unit is configured to cause the pick roller to transport a medium from the stacker to the processing path, and determine whether to transport the medium to the holding unit, based on read data and the indication data, the read data being acquired by reading the medium by the reading unit.

A method, apparatus and program product may evaluate a packaging material to determine various metrics associated with the packaging material. A test apparatus may be used to evaluate packaging material using a take up drum capable of sensing containment force imparted upon the drum by packaging material applied thereto, and in some instances, simulated flaws may be formed in a web of packaging material to evaluate a packaging materials response to such flaws when under tension.

Provided are a medium conveying apparatus, a control method, and a control program is to enable further reduction in the time required for conveying the medium while suppressing the occurrence of the conveyance abnormality of the medium. A medium conveying apparatus includes a conveying mechanism to convey a medium, a determination module to determine whether a conveyance abnormality of the medium has occurred, and a control module to control the conveying mechanism so as to increase a conveyance speed of the medium to be conveyed thereafter, or reduce a conveyance interval of the medium to be conveyed thereafter if the conveyance abnormality of the medium has not occurred when a predetermined number of medium is conveyed.

A sheet conveyance apparatus includes a sheet conveyor configured to convey a sheet, a guide configured to form a conveyance path through which the sheet is conveyed by the sheet conveyor, and a sensor disposed on a same side as the guide with respect to the conveyance path. The guide includes a retracted portion disposed over a first region in a sheet width direction perpendicular to a sheet conveyance direction, the retracted portion being retracted with respect to a second region of the guide in the sheet width direction so as not to come into contact with the sheet passing through the conveyance path, the first region including a detection region of the sensor in the sheet width direction, the second region being a sheet passing region of the sheet in the sheet width direction excluding the first region.

A recording apparatus includes a recording section capable of recording on a medium, a transport belt that is provided with adhesive capable of adhering with the medium and that is capable of transporting the medium, an ultrasonic sensor that transmits ultrasonic waves to the surface of the adhesive and that receives ultrasonic waves reflected from the surface, and a controller capable of determining the state of the surface based on the detection result of the ultrasonic sensor.

Provided is a method of manufacturing a glass roll (GR), including: a conveying step of conveying a band-shaped glass film (G2) in a lateral conveying direction by a conveying device (4); and a roll-up step of rolling up the glass film (G2) into a roll shape. The conveying step includes an inspection step of measuring a state of each of end portions (Gd, Ge) in a width direction of the glass film (G2) by a detection unit (19a, 19b) under a state in which a tension is applied to the glass film (G2) that passes through an intermediate conveying region (MS) of the conveying device (4) by a tension applying portion.

A sheet processing device separates a two-ply sheet in which two sheets are overlapped and partially bonded and sandwich a sheet medium between the two sheets. The sheet processing device includes a relay conveyance path, a sheet loader, and control circuitry. The sheet medium is fed from an image forming apparatus connected upstream of the sheet processing device through the relay conveyance path. The sheet loader loads at least one of the two-ply sheet and the sheet medium. The control circuitry performs a mixing mode to feed the two-ply sheet or the sheet medium from the sheet loader.
