Abstract

A recording apparatus includes a recording portion that records an image on a sheet, a first conveyance path in which a cut sheet serving as the sheet is conveyed toward the recording portion, a second conveyance path in which a continuous sheet serving as the sheet is conveyed toward the recording portion, a common conveyance path in which the sheet is conveyed in a conveying direction from a junction point at which the first conveyance path and the second conveyance path join together to the recording portion, and a control portion that controls the conveyance of the sheet. When the sheet is not detected in the second conveyance path after a sheet conveyance abnormality is detected, while the sheet is detected in the common conveyance path, the control portion performs a discharge operation of conveying the cut sheet from the first conveyance path toward the recording portion.

First claim

What is claimed is:

1. A recording apparatus comprising:
a recording portion that records an image on a sheet;
a first conveyance path in which a cut sheet serving as the sheet is conveyed toward the recording portion;
a second conveyance path in which a continuous sheet serving as the sheet is conveyed toward the recording portion;
a common conveyance path in which the sheet is conveyed in a conveying direction from a junction point at which the first conveyance path and the second conveyance path join together to the recording portion; and
a control portion that controls conveyance of the sheet,
wherein, in a case where the sheet is not detected in the second conveyance path after a sheet conveyance abnormality is detected, the control portion performs a discharge operation of conveying the cut sheet from the first conveyance path toward the recording portion.

2. The recording apparatus according to claim 1 , further comprising:
a first detecting unit disposed in the common conveyance path to detect the sheet; and
a second detecting unit disposed in the second conveyance path to detect the sheet.

3. The recording apparatus according to claim 1 ,
wherein, in a case where the sheet is detected in the second conveyance path after the sheet conveyance abnormality is detected, the control portion conveys the continuous sheet in a direction reverse to the conveying direction.

4. The recording apparatus according to claim 1 ,
wherein the continuous sheet is a roll sheet in which the continuous sheet is wound,
wherein the recording apparatus further comprises a holding portion that holds the roll sheet, and
wherein the continuous sheet is fed from the roll sheet held by the holding portion to the second conveyance path.

5. The recording apparatus according to claim 1 ,
wherein the control portion stops the discharge operation in a case where the sheet is detected in the common conveyance path even after a lapse of a predetermined period after the discharge operation is started.

6. The recording apparatus according to claim 1 , further comprising:
a cutter disposed downstream of the recording portion in the conveying direction to cut the continuous sheet.

7. The recording apparatus according to claim 6 ,
wherein, after the continuous sheet is cut, the control portion performs a returning operation of conveying the continuous sheet in a direction reverse to the conveying direction, and stops the returning operation in a case where the sheet is detected in the second conveyance path after a lapse of a predetermined period.

8. The recording apparatus according to claim 1 , further comprising:
a notifying portion that notifies a sheet conveyance abnormality to a user.

9. The recording apparatus according to claim 8 , further comprising:
an input portion that receives an input of completion of conveyance abnormality handling from the user, and
wherein the control portion performs the discharge operation in a case where, after the notifying portion performs notifying to encourage the user to perform the conveyance abnormality handling and the input portion receives the input, a recording paper is not detected in the second conveyance path, while the recording paper is detected in the common conveyance path.

10. The recording apparatus according to claim 9 ,
wherein, in a case where the recording paper is detected in the second conveyance path after the notifying portion performs the notifying and the input portion receives the input, the notifying portion performs the notifying again.

11. The recording apparatus according to claim 9 ,
wherein, in a case where the recording paper is detected in the second conveyance path after the notifying portion performs the notifying and the input portion receives the input, the control portion performs a returning operation of conveying the continuous sheet in a direction reverse to the conveying direction.

12. The recording apparatus according to claim 11 , further comprising:
a detecting unit that detects a load occurring in a drive unit that conveys the continuous sheet in the returning operation, and
wherein, in a case where a magnitude of the load detected by the detecting unit in the returning operation exceeds a predetermined magnitude, the control portion stops the returning operation, and the notifying portion performs the notifying again.

13. The recording apparatus according to claim 12 ,
wherein the drive unit includes a motor that generates a drive force for conveying the continuous sheet,
wherein the detecting unit detects a value of a current flowing in the motor, and
wherein, in a case where the current value detected by the detecting unit in the returning operation exceeds a predetermined threshold, the control portion stops the returning operation.

14. The recording apparatus according to claim 13 ,
wherein the continuous sheet is a roll sheet in which the continuous sheet is wound,
wherein the recording apparatus further comprises a holding portion that holds the roll sheet,
wherein the drive force generated by the motor is a drive force for rotating the roll sheet held by the holding portion, and
wherein the returning operation is a rewinding operation of rotating the roll sheet in a direction reverse to that of rotation in a case where the continuous sheet extending from the roll sheet is conveyed toward the recording portion and winding the continuous sheet into the roll sheet.

15. The recording apparatus according to claim 1 , wherein after the sheet conveyance abnormality is detected and the sheet is detected in the common conveyance path, the control portion perform the discharge operation.

16. The recording apparatus according to claim 1 , further comprising:
an input portion that receives an input of completion of conveyance abnormality handling from a user,
wherein after the input portion receives the input, the control portion performs the discharge operation.
