  • Patent number: 9248670
    Abstract: A conveyor device is disposed opposite to a recording head. The conveyor device includes a conveyor belt and a suction section. The suction section sucks on a recording medium through the conveyor belt. The suction section includes an air flow chamber and a guide member. The air flow chamber is disposed opposite to one surface of the conveyor belt, and negative pressure for sucking the recording medium onto another surface of the conveyor belt is created in the air flow chamber. The guide member covers the air flow chamber and supports the conveyor belt. The air flow chamber includes a partition wall dividing the air flow chamber into first and second spaces. The first space includes a third space overlapping with the recording head with the conveyor belt and the guide member therebetween. Pressure in the first space is less negative than pressure in the second space.
