Abstract

The recording device includes an adhesive belt extending across a plurality of rotating bodies configured to support and convey a recording medium, a first sensor configured to detect that the recording medium is separated relative to the adhesive belt in a first range, a second sensor configured to detect that the recording medium P is separated relative to the adhesive belt in a second range within the first range, a take-up unit configured to take up the recording medium, and a control unit configured to control the take-up unit so as to take up the recording medium when the first sensor detects that a separation position of the recording medium is within the first range, and control the rotating body to stop movement of the adhesive belt when the second sensor detects that the separation position of the recording medium is within the second range.

First claim

What is claimed is:

1. A recording device, comprising:
an adhesive belt extending across a plurality of rotating bodies that are arranged apart from each other in a first direction, the adhesive belt being configured to support and convey a rolled medium;
a take-up unit configured to take up the rolled medium;
a first sensor configured to detect, in a first range, a separation position where the rolled medium is separated relative to the adhesive belt;
a second sensor configured to detect the separation position in a second range; and
a control unit configured to control the rotating bodies to stop movement of the adhesive belt based on a detection result of at least one of the first sensor and the second sensor, when the control unit performs a take-up control in which the take-up unit and the rotating bodies are both driven.

2. The recording device according to claim 1 , wherein
the control unit is configured to control the rotating bodies and the take-up unit to start the take-up control based on the detection result of the first sensor.

3. The recording device according to claim 1 , wherein
the control unit is configured to control the rotating bodies to stop the movement of the adhesive belt based on the detection result of the second sensor.

4. The recording device according to claim 1 , wherein
the control unit is configured to stop the take-up control based on the detection result of the first sensor.

5. The recording device according to claim 1 , wherein
the first sensor and the second sensor irradiate light from a direction intersecting a surface of the rolled medium, and detect that the rolled medium is separated relative to the adhesive belt by using the light reflected from the surface.

6. The recording device according to claim 1 , further comprising
a recording head configured to move back and forth in a direction intersecting a conveyance direction of the rolled medium and perform recording, wherein
the control unit controls the rotating bodies so that the rotating bodies are intermittently driven according to back and forth movement of the recording head in the direction intersecting the conveyance direction, and
when, during the recording by the recording head, the second sensor detects that the separation position of the rolled medium is within the second range, after the recording has ended according to a movement in one direction among the back and forth movement during the recording, the control unit controls a movement mechanism of the recording head so as to move the recording head to a home position.

7. The recording device according to claim 1 , further comprising
a recording head configured to move back and forth in a direction intersecting a conveyance direction of the rolled medium and perform recording, wherein
the control unit controls the rotating bodies so that the rotating bodies are intermittently driven according to back and forth movement of the recording head in the direction intersecting the conveyance direction, and
when the second sensor detects that the separation position of the rolled medium is within the second range, the control unit controls the rotating bodies so as to stop the movement of the adhesive belt to match a timing when the rotating bodies are not driven according to intermittent driving of the rotating bodies.

8. The recording device according to claim 1 , further comprising
a recording head configured to move back and forth in a direction intersecting a conveyance direction of the rolled medium and perform recording, wherein
the control unit
controls the rotating bodies so that the rotating bodies are intermittently driven according to back and forth movement of the recording head in the direction intersecting the conveyance direction,
controls the second sensor so as to detect whether or not the separation position of the rolled medium is within the second range before the rotating bodies are driven according to intermittent driving of the rotating bodies,
controls the rotating bodies to maintain stopping of the movement of the adhesive belt when the separation position is within the second range, and
controls the rotating bodies so that the rotating bodies are driven to match the drive timing of the rotating bodies according to the intermittent driving when the separation position is not within the second range.
