  • Publication number: 20230391107
    Abstract: A supporting structure for a temperature sensor, and a drying device provided with the supporting structure. The supporting structure includes a front panel, a rear panel, a first supporting member having both ends in a longer-side direction of the first supporting member, and a second supporting member attachable to and detachable from the first supporting member. In the supporting structure, both ends of the first supporting member are removably supported by the front panel and the rear panel. In the supporting structure, the temperature sensor is disposed on the second supporting member, and the temperature sensor detects a surface temperature of a heating roller disposed between the front panel and the rear panel.

  • Publication number: 20220174159
    Abstract: A liquid discharge apparatus includes a first detection unit to detect a first movement amount of a recording medium. The apparatus includes a first liquid discharge unit, a first image capturing unit to capture a first image of the medium in a capturing range between the first detection unit and the first liquid discharge unit, a second image capturing unit to capture a second image of the medium in the capturing range between the first discharge unit and the first capturing unit, a second detection unit to detect a second movement amount of the medium based on the first and second images, a first determining unit to determine a discharge timing of the first discharge unit based on the first and second movement amounts, and a second determining unit to determine a capturing timing of the second capturing unit based on the first and second movement amounts.

  • Publication number: 20220143971
    Abstract: A droplet discharge apparatus includes a control device, a discharge device, and a measuring device. The control device sets conditions for a recording medium or a process using droplets. The discharge device discharges the droplets onto the recording medium. The measuring device measures landing positions of the droplets on the recording medium. The control device calculates a correction amount based on the landing positions, stores the correction amount for each of the conditions, and correct a timing at which the discharge device performs discharge with correction amounts that match the conditions, to correct the landing positions.
