[0022] Outline of recording device

[0023] figure 1 This is a perspective view of the recording device viewed from above.

[0024] The recording device 200 according to the present application rotatably holds a roll medium 1 formed by winding a sheet around a core member, and discharges An inkjet large-format printer that prints with ink. A large-format printer refers to a printer capable of printing and recording on a relatively large-sized sheet such as A0 (841 mm) in short-side width, for example. The roll medium 1 is a roll of paper formed by winding a sheet around a cylindrical core member, and has a plurality of sizes. In addition, as the sheet, paper, resin films, fabrics, and sheet members combining them can be used.

[0025] Such as figure 1 As shown, the recording device 200 is composed of a recording unit 150, a supply device 100, and the like. The recording device 200 has a substantially rectangular parallelepiped shape, and has a structure in which the su...

Abstract

The invention provides a roll medium supply device and a recording apparatus. The roll medium supply device is provided with a pull-out type lower holding part which supports a roll medium shaft and holds the roll medium, and is provided with a guide member which presses and abuts against the roll medium held in the lower holding part from below in the direction of the shaft. And displaces in accordance with a change in the outer diameter of the roll medium. Moreover, the lower holding part can be pulled out from the main body of the supply device in the first direction, and when the pulled-out lower holding part is stored in the main body of the supply device, the guide part abuts against the roll medium and moves downwards from the moving path of the lower holding part against the pressing force from the lower part to the upper part.

Description

technical field [0001] The present invention relates to a supply device of a roll medium and a recording device provided with the supply device. Background technique [0002] Conventionally, there is known a recording device that includes a roll medium such as roll paper and prints on continuous paper supplied from the roll medium. [0003] For example, Patent Document 1 discloses a printing device in which roll paper is set in two sections, one above the other. According to this document, a roll paper is set on a feeder of sheets provided in a printing device. The supply device includes an arm member and a swing member provided at the tip thereof, and is configured to place the roll paper on the arm member from obliquely above. In addition, as the literature Figure 4 As shown in FIG. 2 , the swing member at the tip of the arm member extends substantially horizontally, and its tip is drawn sharply. [0004] According to the description in Patent Document 1, it is presume...
