Claims

A recording apparatus for recording on the recording material while conveying the recording material,
A conveyance drive roller that rotates when a rotational driving force is applied;
A conveyance driven roller that rotates around the recording material with the conveyance drive roller;
A drive unit that applies a rotational drive force to the transport drive roller,
The drive unit is
It includes at least one plate-like piezoelectric element and a pair of electrodes sandwiching the piezoelectric element in the plane direction, and a periodical voltage is applied between each pair of electrodes so that it is perpendicular to the rotation axis of the transport driving roller. A vibrating body that comes into contact with and separates from a flat surface in the surface direction of the piezoelectric element;
A recording apparatus comprising: a vibrating body holding unit that supports the vibrating body with a surface direction of the piezoelectric element parallel to a rotation axis of the transport driving roller.

A frame that pivotally supports the transport drive roller;
A shaft stopper that defines a distance that the transport drive roller can move in the axial direction with respect to the frame;
With
An urging unit that urges the vibrating body against the conveyance drive roller;
The distance that the conveyance drive roller defined by the shaft stopper can move in the axial direction with respect to the frame is smaller than the distance that the vibrating body can move by the urging portion. The recording device described in 1.

The recording apparatus according to claim 2 , further comprising an urging unit that urges the vibrating body and a surface perpendicular to a rotation axis of the transport driving roller in a direction in which the surfaces are pressed against each other.

A liquid ejecting apparatus that ejects liquid onto the recording material while conveying the recording material,
A conveyance drive roller that rotates when a rotational driving force is applied;
A conveyance driven roller that rotates around the recording material with the conveyance drive roller;
A drive unit that applies a rotational drive force to the transport drive roller,
The drive unit is
It includes at least one plate-like piezoelectric element and a pair of electrodes sandwiching the piezoelectric element in the plane direction, and a periodical voltage is applied between each pair of electrodes so that it is perpendicular to the rotation axis of the transport driving roller. A vibrating body that comes into contact with and separates from a flat surface in the surface direction of the piezoelectric element;
A liquid ejecting apparatus comprising: a vibrating body holding portion that supports the vibrating body so that a surface direction of the piezoelectric element is parallel to a rotation axis of the transport driving roller.

A frame that pivotally supports the transport drive roller;
A shaft stopper that defines a distance that the transport drive roller can move in the axial direction with respect to the frame;
With
An urging unit that urges the vibrating body against the conveyance drive roller;
The distance that the conveyance drive roller defined by the shaft stopper can move in the axial direction with respect to the frame is smaller than the distance that the vibrating body can move by the biasing portion. The liquid ejecting apparatus according to 1.

The liquid ejecting apparatus according to claim 5, further comprising an urging unit that urges surfaces that are perpendicular to a rotation axis of the vibrating body and the transport driving roller to press each other.
