Abstract

An image recording apparatus, including: a drive source rotatable forwardly and reversely; a first roller rotatable in a first direction by the forward rotation of the drive source to convey a conveyed medium and rotatable in a second direction reverse to the first direction by the reverse rotation of the drive source; a recording device; a second roller; a first power transmitter which transmits a first-direction driving power to the second roller and not to transmit a second-direction driving power to the second roller, wherein the first-direction driving power is a rotational driving power of the first roller rotating in the first direction, and the second-direction driving power is a rotational driving power of the first roller rotating in the second direction; and a second power transmitter which transmits the second-direction driving power to the second roller and not to transmit the first-direction driving power to the second roller.

Claims13

Dependent claims

A conveying apparatus, comprising:

a drive source configured to perform forward rotation and reverse rotation;
a first roller rotatable in a first direction to convey a conveyed medium in a conveying direction and in a second direction reverse to the first direction;
a second roller disposed downstream of the first roller in the conveying direction, the second roller being rotatable in a third direction to convey the conveyed medium in the conveying direction and in a fourth direction reverse to the third direction;
a first drive mechanism configured to transmit a forward rotational driving power of the drive source to the first roller to rotate the first roller in the first direction and transmit the forward rotational driving power of the drive source to the second roller to rotate the second roller in the third direction, the first drive mechanism being configured to transmit a reverse rotational driving power of the drive source to the first roller to rotate the first roller in the second direction and not to transmit the reverse rotational driving power of the drive source to the second roller;
and
a second drive mechanism configured not to transmit the forward rotational driving power of the drive source to the second roller and configured to transmit the reverse rotational driving power of the drive source to the second roller to rotate the second roller in the fourth direction.
