Conveyor Device and Image Recording Apparatus

An image recording apparatus comprising:

• a first conveyor unit comprising:
• a first roller configured to contact a first surface of a sheet and to be movable in a first radial direction;
• and
• a second roller configured to contact a second surface of the sheet,
• wherein the first roller and the second roller are configured to nip and convey the sheet along a conveyance path in a conveyance direction;
• a second conveyor unit disposed along the conveyance path and comprising:
• a third roller configured to contact the second surface of the sheet and to be movable in a second radial direction;
• and
• a fourth roller configured to contact the first surface of the sheet,
• wherein the third roller and the fourth roller are configured to nip and convey the sheet in the conveyance direction;
• a recording head disposed along the conveyance path between the first conveyor unit and the second conveyor unit and configured to record an image onto the sheet being conveyed along the conveyance path between the first conveyor unit and the second conveyor unit;
• and
• a movable member configured to be movable between a first position and a second position, wherein when the movable member is located in the first position, the first roller is in contact with the second roller and the third roller is in contact with the fourth roller, and when the movable member is located in the second position, the first roller is separated from the second roller and the third roller is separated from the fourth roller,
• wherein a distance from the third roller to the recording head in the second position is greater than a distance from the third roller to the recording head in the first position while a distance from the second roller to the recording head is the same in the first position and the second position.

A conveyor device comprising:

• a first conveyor unit comprising:
• a first roller configured to contact an upper surface of a sheet and to be movable;
• and
• a second roller configured to contact a lower surface of the sheet,
• wherein the first roller and the second roller are configured to nip and convey the sheet along a conveyance path in a conveyance direction;
• a second conveyor unit disposed along the conveyance path and comprising:
• a third roller configured to contact the lower surface of the sheet and to be movable;
• and
• a fourth roller configured to contact the upper surface of the sheet,
• wherein the third roller and the fourth roller are configured to nip and convey the sheet in the conveyance direction;
• and
• a movable member configured to be movable between a first position and a second position, wherein when the movable member is located in the first position, the first roller is in contact with the second roller and the third roller is in contact with the fourth roller, and when the movable member moves to the second position, the first roller is moved away from the second roller while the second roller remains in a static position and the third roller is moved away from the fourth roller while the fourth roller remains in a static position.
