Description

  The present invention relates to an ink jet recording apparatus.

  2. Description of the Related Art Conventionally, some inkjet recording apparatuses feed and convey a sheet-like recording medium wound in a roll shape.

The ink jet recording apparatus described above can be used by appropriately replacing recording media of various materials, thicknesses, lengths, etc., and is used for properly recording images. Various information regarding the recording medium to be recorded is required.
Specifically, for example, when a roll-shaped recording medium is fed out, the recording medium is loosened due to elongation of the recording medium due to excessive tension, uneven tension in the width direction of the fed recording medium, or the like. Since wrinkles or the like may occur and the recording quality may deteriorate due to a paper jam or a decrease in the plane accuracy of the recording medium during image recording, the distance between the recording head and the recording medium is maintained at a predetermined interval. There is a need to. For this purpose, it is necessary to control the rotation speed of the roll according to the outer diameter of the roll of the storage medium.
In order to control the rotation speed of the roll, it is necessary to grasp the outer diameter of the roll that changes due to feeding, in addition to information on the material, thickness, and width of the storage medium.
However, if the roll-shaped recording medium is used again after being exchanged during use, the outer diameter of the roll is not known and the rotation speed of the roll cannot be controlled appropriately.

Therefore, for example, a detection means such as an ultrasonic sensor for detecting the rotation state of the roll is provided on the end surface side of the roll shaft on which the recording medium is wound in a roll shape, and the radius of the roll is detected using this detection means. By doing so, an image forming apparatus that controls conveyance of a recording medium is known (see, for example, Patent Document 1).
As described above, various kinds of information relating to the recording medium are indispensable when performing image recording properly.

However, since the recording medium is used after being changed many times during use, it is necessary to input and set necessary information every time the recording medium is replaced. There has been a problem that replacement of a recording medium for which conditions are not set is restricted.
Further, in the conveyance control of the recording medium, the rotational speed of the roll is calculated in time series based on the detection signal from the detection means such as the ultrasonic sensor as in the above-mentioned Patent Document 1, and the control of the drive motor is performed. Since the drive voltage and the number of pulses related to the above are calculated, there has been a problem in design restriction that the detection means must be provided.

Thus, the rotational speed and drive torque of the drive motor 113b are controlled.
That is, the recording medium S held in the recording medium holding unit 112 is shortened in length as the image recording operation by the inkjet recording apparatus 100 progresses, and the recording medium S wound around the paper tube R is reduced. As the outer diameter of the roll decreases, the weight of the recording medium S held by the recording medium holding unit 112 decreases.

The medium weight data d2 stored in the IC tag 116 can be corrected.
The CPU 7 can appropriately transport the recording medium S by controlling the rotational speed and driving torque of the driving motor 113b based on the corrected roll diameter data d1 and medium weight data d2. That is, the length and weight of the recording medium S held by the recording medium holding unit 112 are reduced as the recording medium S is transported, and the outer diameter and weight of the roll of the recording medium S are reduced. Even in this case, by correcting the roll diameter data d1 and the medium weight data d2, it is possible to appropriately control the rotational speed and the driving torque by the driving motor 113b. The conveying operation of the recording medium S can be performed appropriately without providing any means.
