Abstract

A recording apparatus includes a conveyance roller for conveying a recording medium to a recording area; a drive source for generating a drive force for driving the conveyance roller; a feeding roller for feeding the recording medium to the conveyance roller, the feeding roller being driven by the drive source; a switching unit for selectively switching between a state in which the drive force is transmitted to the feeding roller, and a state in which the drive force is shut off from the feeding roller; and a control unit for controlling a switching operation performed by the switching unit under a predetermined condition. In the recording apparatus, when a recording operation on the recording medium is continuously performed by the recording head, if the predetermined condition is satisfied, the control unit controls the switching unit so that the drive force is transmitted from the drive source to the feeding roller.

Claims

1. A recording apparatus comprising:

a conveyance roller configured to convey a recording medium to a recording area in which recording is performed by a recording head;

a drive source configured to generate a drive force for driving the conveyance roller;

a feeding roller configured to feed the recording medium to the conveyance roller, the feeding roller being driven by the drive source;

a switching unit configured to selectively switch between a state in which the drive force is transmitted from the drive source to the feeding roller, and a state in which the drive force is shut off from the feeding roller; and

a control unit configured to control a switching operation performed by the switching unit under a predetermined condition,

wherein even when a recording operation on the recording medium is continuously performed by the recording head, if the predetermined conditions are satisfied, the control unit controls the switching unit so that the drive force is transmitted from the drive source to the feeding roller.

2. The recording apparatus according to claim 1, wherein the switching unit includes a solenoid configured to perform the switching operation.

3. The recording apparatus according to claim 1, further comprising:

a carriage mounted with the recording head and configured to make a reciprocating motion in a direction orthogonal to a direction of conveyance of the recording medium,

wherein the switching unit includes an operation portion abutting the carriage, and

wherein the switching unit performs the switching operation in accordance with an operation of the operation portion by the carriage.

4. The recording apparatus according to claim 1, wherein the switching unit performs the switching operation when the conveyance roller is rotated by a predetermined amount in a direction opposite to an ordinary direction of conveyance of the recording medium.

5. The recording apparatus according to claim 1, wherein the predetermined conditions include a length of the recording medium in the direction of conveyance of the recording medium, and

information related to the length of the recording medium in the direction of conveyance of the recording medium is included in data input into the recording apparatus from an external apparatus.

6. The recording apparatus according to claim 1, further comprising:

an edge detection unit configured to detect an edge of the recording medium conveyed by the conveyance roller,

wherein the predetermined conditions include the length of the recording medium in the direction of conveyance of the recording medium, and

wherein the information related to the length of the recording medium is obtained by the edge detection unit which detects an edge of the recording medium conveyed by the conveyance roller.
