no. 1 approach

[0031] Hereinafter, a first embodiment of the printer will be described with reference to the drawings.

[0032] Such as figure 1 As shown, the printer 11 of the present embodiment includes a substantially rectangular box-shaped housing portion 12 . The housing part 12 includes a first storage part 13 , a second storage part 14 arranged on the -Z side in the vertical direction Z of the first storage part 13 , and a third storage part 14 arranged on the rear side of the first storage part 13 . Storage section 15 .

[0033] The drawer unit 16 is accommodated in the case portion 12 so as to be extractable through an opening portion 25 formed near the center in the width direction X of the first accommodation portion 13 . In the present embodiment, the drawer unit 16 has a front plate portion 35 whose outer surface is exposed as a front surface when it is housed in the case portion 12 .

[0034] The storage container 17 is detachably attached to a position parallel to the front...

no. 2 approach

[0182] Hereinafter, a second embodiment of the printer will be described with reference to the drawings. In the first embodiment, if figure 2 As shown, the inner peripheral surface of the medium P is the second surface. In contrast, in the second embodiment, as Figure 20 As shown, the point that the inner peripheral surface of the medium P is the first surface is different from the above-mentioned first embodiment. In other points, since the second embodiment is substantially the same as the first embodiment, the same reference numerals are assigned to the same structures to omit repeated descriptions.

[0183] Such as Figure 20 As shown, the path forming member 45 supports a positioning member 47 movable in the width direction X along a guide hole (not shown). The positioning member 47 has a protrusion that protrudes further in the drawing direction D1 than the guide hole (not shown). In addition, it is different from the first embodiment in that the path forming membe...

Abstract

The invention provides a printer and a control method of a printer. The printer includes: a transport unit that transports, in a transport direction, a medium unwound from a state in which the medium is wound into a roll; a printing unit that can be moved to a position where a nozzle surface does not face the medium; and a control unit. In inner circumferential surface printing for performing printing on an inner circumferential surface of the medium, which is positioned inside in the state of being wound up in a roll shape, the control unit causes the transport unit to position a leading end of the medium at a printing start position being a position downstream of a position facing a most downstream nozzle of the nozzle surface in a transport direction, in a state in which the printing unit is at a position at which the nozzle surface does not face the medium being transported by the transport unit, and causes the printing unit to start formation of a printing region on the medium having the leading end positioned at the printing start position.

Description

technical field [0001] The present invention relates to a printer for printing by ejecting liquid onto a medium and a control method for the printer. Background technique [0002] Conventionally, a structure that prints on the inner surface of a roll body is known as a device for printing and cutting a roll paper. In the printer described in Patent Document 1, there is disclosed a configuration in which printing is performed with the inner side of a long medium wound into a roll as the back side in double-sided printing. [0003] In the printer described in Patent Document 1, since the medium is long and rolled into a roll, when the inner surface is positioned on the side of the printing section, it is wound up when it is wound into a roll. Curls in the direction toward the printing section side occur at the leading end of the medium. In an inkjet printer, it is assumed that there is a gap between the printing unit and the medium. Therefore, when a carriage mounted with a...
