Recording apparatus and recording method
A recording apparatus includes a recording section that performs recording on a recording medium, a rotation section that sends out the recording medium by rotating a roll of the recording medium or rolls up the recording medium into a roll, and a roll diameter estimation section that estimates the roll diameter of the recording medium present in the rotation section. The roll diameter estimation section is capable of estimating the roll diameter during the recording performed by the recording section. The thus-configured recording apparatus estimates the roll diameter of the recording medium in real time during recording.
1. A recording apparatus comprising:
a recording section including a recording head that performs recording on a recording medium;
a rotation section that rotates the recording medium in a rolled state;
a roll diameter estimation section that estimates a roll diameter of the recording medium present in the rotation section, the roll diameter estimation section being capable of estimating the roll diameter during the recording performed by the recording section; and
a rotation load estimation section capable of estimating a rotation load on the rotation section during the recording performed by the recording head based on the roll diameter estimated by the roll diameter estimation section,
wherein the roll diameter estimation section estimates if the roll of the recording medium has rotated at least a predetermined amount of rotation in a rotation direction prior to estimating the roll diameter.
2. The recording apparatus according to claim 1 , further comprising a transport section that transports the recording medium,
wherein the roll diameter estimation section is capable of estimating the roll diameter based on an amount of transport of the recording medium caused by the transport section and an amount of rotation of the rotation section.
3. The recording apparatus according to claim 1 , wherein the rotation section is a send-out section that sends out the recording medium.
4. The recording apparatus according to claim 1 , wherein the rotation section is a take-up section that rolls up the recording medium.
5. A recording method for a recording apparatus that includes
a recording section including a recording head that performs recording on a recording medium, and
a rotation section that rotates the recording medium in a rolled state, the recording method comprising:
estimating if a roll of the recording medium has rotated at least a predetermined amount of rotation in a rotation direction prior to estimating a roll diameter of the recording medium;
estimating the roll diameter of the recording medium during the recording performed by the recording head of the recording section; and
estimating a rotation load on the rotation section during the recording performed by recording head, based on the roll diameter estimated in the estimating of the roll diameter.
6. The recording method according to claim 5 ,
wherein the recording apparatus further includes a transport section that transports the recording medium, and
wherein the estimating of the roll diameter is performed based on an amount of transport of the recording medium caused by the transport section and an amount of rotation of the rotation section.
