Description

Recording apparatus and recording method Technical Field The present invention relates to a recording apparatus such as a printer and a recording method. Background An example of a conventional technology of such a device is disclosed in patent document 1. When the fabric is directly printed, stretching and contraction are likely to occur, and the fabric is likely to be deformed. As means for suppressing the expansion and contraction, there is a method of adhering a fabric to an adhesive sheet and printing the fabric. However, when the user performs a work of adhering the fabric to the adhesive sheet, the pressing force for adhering varies depending on the user, and it is difficult to always obtain a predetermined adhesive force. Patent document 1 discloses an image forming apparatus including an adhesion unit for adhering a print substrate (film) fed from a roll to an adhesion surface of a support substrate (film) fed from a roll-shaped feed roll to form a composite substrate. The adhesive on the adhesive surface has a difference in predetermined adhesion force depending on compatibility with the fabric. Therefore, the pressing force of the adhesion unit needs to be adjusted according to the kind of the adhesive and the kind of the fabric, however, in the above-mentioned patent document 1, no consideration is given to the adjustment of the pressing force. When the fabric is pressed with a force smaller than a predetermined adhesive force, the fabric may be peeled off from the adhesive sheet to cause printing failure when the fabric passes through a portion of a buckling path or a conveying roller and when printing is performed by ejecting ink onto the fabric. In addition, when the fabric is pressed with a force larger than a predetermined adhesive force, a load more than necessary may be applied to the fabric to cause damage to the fabric when the fabric is peeled from the adhesive sheet. Patent document 1 Japanese patent application laid-open No. 2013-6315 Disclosure of Invention In order to solve the above-described problems, a recording apparatus according to the present invention includes an unreeling portion for unreeling a roll-shaped medium formed by adhering a fabric to a support member having an adhesive surface in a transport direction, a recording portion for recording on the medium, a pressing portion that is located upstream in the transport direction from the recording portion and that clamps and presses the medium moving in the transport direction, and an adjusting portion that can adjust a pressing force against the medium generated by the pressing portion. Further, a recording method according to the present invention is characterized in that a roll-shaped medium formed by adhering a fabric to a support member having an adhesive surface is unwound in a transport direction, the unwound medium is sandwiched and pressed by a pressing portion, a pressing force against the medium by the pressing portion is adjusted according to a type of the medium, and recording is performed on the medium by a recording portion at a position downstream in the transport direction from the pressing portion.
