摘要： An inkjet printer includes a plurality of rollers, an endless transportation belt, a belt rotating mechanism, a recording unit, a printing medium supply mechanism, and a control unit. The transportation belt is laid on the rollers and defines a first recess portion, which extends in a direction perpendicular to a printing medium transporting direction, in an outer circumferential surface thereof. The belt rotating mechanism applies a rotating force to the transportation belt. The recording unit is disposed to face the transportation belt and forms an image. The printing medium supply mechanism supplies a printing medium onto the transportation belt. The control unit controls at least one of the belt rotating mechanism and the printing medium supply mechanism so that when the printing medium is on the transportation belt, one of front and rear end portions of the printing medium is located in the first recess portion.

摘要： An ink-jet recording apparatus comprises rollers, an endless conveyor belt, a nip roller, and an ink-jet head. The endless conveyor belt is stretched between the rollers. The nip roller cooperates with an outer surface of the conveyor belt to sandwich a recording medium. The ink-jet head has nozzles from which ink is ejected to the recording medium that is conveyed in a predetermined conveyance direction by the conveyor belt. The conveyor belt has a base member, an elastic layer formed on an outer surface of the base member, and an adhesive layer formed on an outer surface of the elastic layer and holding thereon the recording medium. The elastic layer deforms in its thickness direction when the recording medium is sandwiched between the adhesive layer and the nip roller.

摘要： A liquid ejecting apparatus has a movement mechanism, a pressurized purge unit, and a liquid discharge restriction mechanism. The movement mechanism moves at least one of a liquid ejecting head and a cap so as to allow the cap to take a capping position where the cap covers a liquid ejection face of the head or an uncapping position where the cap is spaced away from the liquid ejection face and capable of receiving liquid ejected from nozzles formed on the liquid ejection face. The pressurized purge unit makes liquid forcibly ejected from the nozzles into the cap. The liquid discharge restriction mechanism restricts liquid from being discharged through a discharge port of the cap when the cap is in the capping position, and permits liquid to be discharged through the discharge port when the cap is in the uncapping position.
