[0077] Hereinafter, embodiments of the present invention will be described with reference to the drawings. figure 1 It is a front perspective view showing the configuration of the inkjet printer 100 including the transport device 115 . figure 2 It is a rear perspective view showing the configuration of the inkjet printer 100 including the transport device 115 . image 3 Yes figure 1 The sectional view along the I-I line.

[0078] In this specification, "medium" includes paper such as plain paper, various recording media made of resin materials such as PVC and polyester, and various materials such as aluminum, iron, and wood.

[0079] In this specification, the width direction of the medium 300 is appropriately referred to as a "main scanning direction". Furthermore, the direction perpendicular to the main scanning direction is appropriately referred to as a "sub-scanning direction".

[0080] In this specification, "inkjet method" includes conventionally known inkjet pri...

no. 2 approach

[0164] like Figure 12 As shown, the inkjet printer 100 also includes a sensor 58 . The sensor 58 is provided on the left side of the ink head 130 . The sensor 58 moves in the X-axis direction together with the ink head 130 . The sensor 58 acquires an X-coordinate value of an end portion of the medium 300 on the platen 122 in the X-axis direction (main scanning direction) when the ink head 130 moves in the X-axis direction. In addition, the sensor 58 may also be disposed on the right side of the ink head 130 .

[0165] like Figure 13 As shown, the microcomputer 60 includes: a storage unit 62 for storing various data such as input print image data; a first print unit 64 for performing predetermined printing on the medium 300 based on the print image data; The second printing unit 66 for adjusting the scale of the medium 300 is printed using the setting value of the storage unit 62 .

[0166] The storage unit 62 stores various types of data, such as data for printing image...

Abstract

A carrier device includes a medium accommodating section configured to accommodate a roll medium, a carrying section configured to carry a medium in a secondary scanning direction, a re-rolling section configured to re-roll the medium having been carried, a dancer roller configured to apply a predetermined tension on the medium being carried from the carrying section toward the re-rolling section, a first bar-shaped member disposed between the medium accommodating section and the carrying section configured to press the medium so as to alter the carrying path of the medium; and a second bar-shaped member disposed between the carrying section and the re-rolling section configured to press the medium so as to alter the carrying path of the medium.

Description

technical field [0001] The present invention relates to a transport device, an inkjet printer equipped with the transport device, and a transport method. Background technique [0002] Conventionally, there are known a conveyance device that conveys a long medium, and an inkjet printer that prints a desired image by ejecting ink from an ink head onto the medium conveyed by the conveyance device. [0003] As a conveying device, the conveying device of a roll-to-roll (roll to roll) system is mentioned, for example. In the roll-to-roll system, a long medium wound into a roll is unwound and conveyed, and the conveyed medium is wound into a roll. [0004] In an inkjet printer including a roller-to-roll conveyance device, the ink head moves in a direction perpendicular to the conveyance direction of the medium (sub-scanning direction) to eject ink onto the medium to perform desired printing. [0005] like Figures 27A-27C As shown, an inkjet printer 200 including a roll-to-roll t...
