  • Publication number: 20220379648
    Abstract: An image forming apparatus includes: a pretreatment section that applies a precoat liquid to a printing surface of a continuous recording medium to be transported; a printing section that sprays ink onto the continuous recording medium to which the precoat liquid is applied; and a transport section that transports the continuous recording medium along a predetermined path. The transport section includes at least one pass roller that is disposed between the pretreatment section and the printing section, the pass roller transporting the continuous recording medium to which the precoat liquid is applied toward the printing section and coming into contact with the printing surface of the continuous recording medium. A surface of the pass roller is subjected to water-repellent finishing for the precoat liquid.

  • Publication number: 20220370014
    Abstract: A biological signal detection device is capable of accurately and simply measuring biological signals and promotes daily health care. A body abutting-side cushioning member 10 formed of a three-dimensional knitted fabric is substantially circular in plan view. A base cushioning member 20 is also substantially circular in plan view. A square one tends to undergo deformation such as turning-up or folding of its edges around the corners when, for example, a person sits thereon. Such deformation tends to distort detection data. Moreover, the folding and the like give a feeling of something foreign. In contrast, a substantially circular one less undergoes such folding and the like.

  • Publication number: 20220351092
    Abstract: A space staging method includes a reservation information acquisition step, an entry detection step, a determination step, and a staging execution step. The reservation information acquisition step is a step of acquiring reservation information about a reservation of a target space of a facility from a server. The entry detection step is a step of detecting whether a user specified by the reservation information has entered a specific space in the facility. The determination step is a step of determining a number of times of entry of the user into the specific space upon detection of entry of the user into the specific space in the entry detection step. The staging execution step is a step of causing a staging system generating a stimulus to at least one of five senses of human in the facility to execute staging processing.

  • Publication number: 20220317604
    Abstract: An image forming apparatus includes a fixing section, a detection section, and a controller. The detection section detects a passing range of a recording medium in terms of a direction intersecting with a conveyance direction of the recording medium. A heating section of the fixing section includes a first heater and a second heater. The first heater has a longitudinal direction extending in an axis direction. The second heater has a longitudinal direction extending in terms of the axis direction from each of opposite ends of the first heater in terms of the axis direction. When a result of detection by the detection section indicates that the passing range of the recording medium does not overlap with a specific range of the second heater, the controller restricts heat generation by the second heater.
