Abstract: Provided are a medium conveying device and an inkjet printer that can convey a medium stably. In a case where a paper P is conveyed along a plane in a conveying unit 40, a posture of the paper P is corrected by a posture correction unit 20, and then the paper P is delivered to the conveying unit 40 by a delivery unit 30. The delivery unit 30 holds a leading end portion of the paper P of which the posture is corrected by the posture correction unit 2 with a paper holding bar 31, and delivers the paper P to the conveying unit 40 by moving the paper holding bar 31 linearly along a conveying direction of the paper P by the conveying unit 40.

Abstract: A liquid supplying mechanism includes a control unit that controls a first pressure adjusting unit and a second pressure adjusting unit by control parameters each having a given initial value on the basis of a supply pressure detected by a first detecting unit and a discharge pressure detected by a second detecting unit, respectively, so that the supply pressure is higher than the discharge pressure while a back pressure at a nozzle surface is maintained at a given value, and when deviations of the detected supply pressure and the detected discharge pressure with respect to the corresponding target pressure value exceed a given reference value, controls each of the first pressure adjusting unit and the second pressure adjusting unit by changing the control parameters from the initial values.

Abstract: A sheet stacking device (77) is provided with a sheet discharge platform (76) on which image forming sheets (P), which have been subjected to heating and drying processing after images are formed using ink, are stacked; and a nozzle (162) that blows air to a side surface of a sheet bundle in a horizontal direction. Air is blown to the sheet bundle stacked on the sheet discharge platform (76) while the height of the sheet discharge platform (76) is adjusted by a sheet discharge platform raising and lowering device (100) so that a gap is formed between the sheets in the vertically middle portion of the sheet bundle. According to the sheet stacking device (77), a plurality of image forming sheets (P) can be efficiently cooled on the sheet discharge platform. Accordingly, the occurrence of blocking can be suppressed.

Abstract: There is provided a print medium-conveying device and an inkjet printing device that can convey a print medium without causing wrinkles, float and damage. In an embodiment, the front surface of paper passed to an image recording drum is pressed by a pressure roller, and is made to contact the peripheral surface of the image recording drum. The front surface of paper is sucked by a suction unit in a position immediately before it enters between the image recording drum and the pressure roller, and back tension is given. The back tension giving is turned on/off according to the thickness of the paper, and the back tension giving is turned off for paper whose thickness is equal to or greater than a threshold. It is possible to prevent paper with stiffness from strongly contacting an adsorption holding surface of the suction unit and the front surface from being damaged.

Abstract: A thickness of a recording medium to be held in a holding region of an outer circumferential part of a cylindrical portion having plural suction holes and a suction position positioned in a predetermined direction from a position of a shaft is acquired. In a case where the thickness of the recording medium is equal to or greater than a first threshold value, a suction flow rate of each suction hole disposed in a subsequent region other than a leading edge of the recording medium is set as a first suction flow rate, and a suction flow rate of each suction hole disposed in the leading edge is set as a second suction flow rate which is smaller than the first suction flow rate. In a case where the thickness of the recording medium is smaller than the first threshold value, a suction flow rate of each suction hole disposed in the holding region is set as a third flow rate which is smaller than the first flow rate.
