  • Publication number: 20190240975
    Abstract: An inkjet recording apparatus (1) includes an image forming section (40), a decurler (20), a changing section (50), a first calculating section (72), storage (60), a second calculating section (73), and a controller (75). The image forming section (40) ejects ink onto a sheet (S). The decurler (20) bends the sheet (S). The changing section (50) changes a bending amount of the sheet (S). The first calculating section (72) calculates an ink ejection rate (?) to the sheet (S) for each of areas of the sheet (S). The storage (60) stores therein first bending information (62) indicating a first target bending amount (?) of a specific area of the sheet (S) corresponding to the ink ejection rate (?) to the specific area. The second calculating section (73) calculates a second target bending amount of each of the areas. The controller (75) controls the changing section (50) based on the second target bending amounts.

  • Patent number: 10350909
    Abstract: A decurling device includes a first conveyance path, a second conveyance path, a first switch, a decurler, and a controller. A sheet is conveyed along the first conveyance path or the second conveyance path. The first switch switches a route of conveyance of the sheet to the first conveyance path or the second conveyance path. The sheet has a first main surface and a second main surface. The decurler is located in the second conveyance path. The decurler corrects curl of the sheet. In a situation in which a weight per unit area of the sheet is smaller than a first threshold value, the controller controls the first switch such that the sheet is conveyed along the second conveyance path.

  • Publication number: 20150246560
    Abstract: Provided is a recording material discharge device including a recording material discharge member that discharges recording materials, and a recording material accommodating unit that accommodates the plural recording materials which are discharged from the recording material discharge member, wherein a discharge velocity of a first recording material discharged by the recording material discharge member is lower than a discharge velocity of each of second and subsequent recording materials.

  • Patent number: 8613437
    Abstract: A sheet identification device includes plural detecting units, an estimating unit, and an output unit. The plural detecting units are provided along a transport path along which a sheet is transported by a transport unit, and detect passing of the sheet. The estimating unit estimates a length in a transport direction of the sheet as a detection target on the basis of individual detection results generated by the plural detecting units. The output unit outputs, if the length estimated by the estimating unit on the basis of at least one of the detection results is not a predetermined length, a signal indicating that a sheet having a length in the transport direction different from the predetermined length is being transported.

  • Publication number: 20090164068
    Abstract: A vehicle behavior control device to control a yawing movement of a vehicle during a circling movement thereof, the device comprising a control start decision means 38 that starts a vehicle behavior control by starting a control as to a braking force difference between vehicle wheels when a value of a yaw angular velocity deviation ?? that is a deviation between a command yaw angular velocity and an actual yaw angular velocity, and a value of a steering wheel angular velocity ?v exceed a prescribed standard thresholds; wherein the control start decision means 38 starts or stops the control as to the braking force difference by determining whether a threshold is greater or smaller than a standard threshold when the yaw angular velocity deviation ? is estimated as being on the increase or decrease based on the steering wheel angular velocity ?v.

  • Patent number: 6543923
    Abstract: A vehicle lamp such as a rear combination lamp comprising: a reflex reflector lens that is fitted in a front lens of the lamp so as to reflect the light from the outside the vehicle lamp back to the outside, and a light reflector that is formed in the front lens so as to face the reflex reflector lens and to entirely reflect the light from a light source toward the light source. The vehicle reflex reflector lens is made of a material that has a lower heat resistance than the front lens.
