8. The image recording device according to claim 1 , wherein the return guide is pivotable about an axis parallel to the pivot shaft for the feed arm.
9. The image recording device according to claim 1 , wherein the second tray is configured to, when at the second position, support the return guide.
10. An image recording device comprising:
a first tray including a first sheet support surface configured to support sheets thereon;
a second tray including a second sheet support surface configured to support sheets thereon, the second tray being configured to move, relative to the first tray, between a first position and a second position;
a pivot shaft;
a sheet feeder configured to feed a sheet from one of the first tray and the second tray, the sheet feeder including:
a feed arm pivotable about the pivot shaft passing through one end portion of the feed arm: and
a feed roller supported by the other end portion of the feed arm, the feed roller being configured to, when the second tray moves from the first position toward the second position, move away from the first sheet support surface and toward the second sheet support surface;
a recording unit configured to record an image on the sheet fed by the sheet feeder;
a return guide including:
a first guide surface defining a part of a return path and extending over at least a portion of the sheet feeder and configured to guide the sheet having the image recorded thereon along the return path back toward the recording unit;
a surface opposite to the first guide surface; and
a support portion supporting the pivot shaft such that the feed arm is pivotable toward and away from the surface opposite to the first guide surface,
wherein the first sheet support surface of the first tray and the second sheet support surface of the second tray extends horizontally, and the first guide surface of the return guide is parallel to the first sheet support surface and the second sheet support surface, and
wherein when the second tray is at the second position, the sheet feeder is located between the surface opposite to the first guide surface of the return guide and the second sheet support surface of the second tray.
11. The image recording device according to claim 10 , wherein the return guide further includes a second guide surface located downstream of the first guide surface in a direction in which the sheet is guided, the second guide surface being inclined upward relative to the first guide surface.
