A conveying apparatus includes: a first roller and a second roller configured to convey a print sheet while nipping the print sheet at a nip pressure; an adjustor supporting the first roller and the second roller in a manner capable of adjusting an inter-axial distance between the first roller and the second roller, the adjustor being configured to apply a biasing force biasing the second roller toward the first roller and capable of adjusting the biasing force; and a controller configured to control the nip pressure by driving the adjustor to adjust the biasing force.

An image forming apparatus includes: a conveyance section configured to convey a sheet in a direction opposite to a first conveyance direction during image formation, the direction being a second conveyance direction; and a distortion correction section disposed on an upstream side of a transfer nip in the first conveyance direction and configured to correct, when the sheet is conveyed by the conveyance section in the second conveyance direction, distortion of the sheet generated when the sheet passes through a fixing nip.

A method of manufacturing a glass roll, includes: a forming step (S1) of forming, while conveying a glass film, the glass film by a downdraw method; a temporary rolling step (S3) of rolling the glass film while superposing a protective film on the glass film at a downstream end of a path of the conveying in the forming step (S1), to thereby manufacture a source glass roll; and a main rolling step (S4) of unrolling, while conveying the glass film to a downstream side, the glass film from the source glass roll, and then rerolling the glass film while superposing a protective film on the glass film at a downstream end of a path of the conveying, to thereby manufacture a glass roll. Higher tension in a rolling direction is applied to the glass film in the main rolling step (S4) than in the temporary rolling step (S3).

A system includes a component inspection system having a radiation source configured to generate radiation and a radiation detector configured to detect the radiation after the radiation passes through components to be inspected. The system also includes a fixture configured to receive multiple reels that are each configured to receive a tape in or on which the components are located. The fixture includes a base configured to be secured to a support, a shaft, one or more motors mounted to the shaft and configured to rotate the reels, and one or more joints coupling the shaft and base. The one or more joints are configured to allow (i) rotation of the shaft about a longitudinal axis of the shaft to change an orientation of the shaft with respect to the base and (ii) rotation of the shaft to change a direction at which the shaft extends away from the base.

A slitter device includes a first tension detecting unit for obtaining a raw-cloth tension value which is a tension value of a sheet material fed out from a let-off mechanism, a second tension detecting unit for obtaining a divided material tension value which is the sum of the tension values of each of divided sheet materials, and a drive control device which includes a comparator to which the first tension detecting unit and the second tension detecting unit are connected, and which compares the raw-cloth tension value and the divided material tension value with each other; and a drive controller which controls an operating state of a roll driving motor such that the raw-cloth tension value and the divided material tension value coincide or substantially coincide with each other based on the comparison result of the comparator.

A winding device includes a first roller that winds label roll paper that is composed with a continues base sheet, a plurality of labels and a marginal portion, a second roller that winds the marginal portion peeled off the label roll paper, a drive part that generates a driving force for the second roller to rotate, a drive transmission control part that is provided between the drive part and the second roller such that the driving force is transmitted to the second roller from the driving part, and stops transmitting the driving force to the second roller if a load placed on the second roller exceeds a prescribed load, a detection part that detects a rotation of the second roller, and a control part that determines a cutoff of the marginal portion based on the rotation of the second roller detected by the detection part.

A printing apparatus includes: a ribbon supply roll; a thermal head that heats an ink ribbon fed out from the ribbon supply roll and thereby transfers an ink onto an image receiving body; a ribbon take-up roll that takes up the ink ribbon after transfer of the ink; a supply side guide member disposed to be displaced in a direction orthogonal to an axial direction, so as to changeably apply tension to the ink ribbon by biasing force of a supply side spring member; and a take-up side guide member disposed to be displaced in a direction orthogonal to an axial direction, so as to changeably apply tension to the ink ribbon by biasing force of a take-up side spring member. A spring constant of the supply side spring member is different from a spring constant of the take-up side spring member.

A slit-cutting device includes a first holder, a second holder, a first contactable member a second contactable member, and a protrusion member. The first holder includes a medium faceable area and a first contactable member. The second holder holds a blade and includes a second contactable member. A cutting edge of the blade may cut a medium between the first holder and the blade. The first contactable member and the second contactable member contact each other and defined a closest approach distance between the cutting edge and the first holder. The closest approach distance is longer than zero and below a thickness of the medium. The protrusion member protrudes more than the closest approach distance from a part of the medium faceable area. The cutting edge may make a cut line includes at least a part of a slit-cut and a full-cut in a cutting edge direction in the medium.

The present disclosure is a sheet producing device for producing a multi-layer sheet by applying a coating material to a sheet material. The sheet producing device includes a radiation light source that emits radiation light, a division part that divides the radiation light into measurement light to be incident on the multi-layer sheet and reference light with which a reference surface is to be irradiated, and an optical member that emits the measurement light onto the multi-layer sheet and receives the measurement light reflected by the multi-layer sheet. An interference detector that detects interference light between the measurement light reflected by the multi-layer sheet and the reference light reflected by the reference surface, and a thickness calculator that calculates a thickness of the sheet material and a thickness of the coating material of the multi-layer sheet based on the detected interference light are further included. As a result, the tact time from the production of the multi-layer sheet to the calculation of the thickness can be shortened.
