Embodiment 1

[0032] [Example 1]( Figure 1 to Figure 6 )

[0033] First, the outline of the printing apparatus according to Embodiment 1 of the present invention will be described.

[0034] figure 1 This is a schematic side view of the printing apparatus 1 according to this embodiment.

[0035] In the printing apparatus 1 of the present embodiment, the medium M is transported in the transport direction A. As shown in FIG. In addition, the printing apparatus 1 of the present embodiment includes a holding unit 15 capable of holding the medium M for printing. The holding part 15 has the support shaft 2 holding the roll R1 of the roll-shaped medium M. In addition, the holding portion 15 has a structure capable of holding the paper tube 16 on which the medium M is wound from both sides in the width direction B (the direction intersecting the conveyance direction A), and is provided on the deep side and the front side in the drawing. two. But when figure 1 In the figure, the holding part ...

Embodiment 2

[0066] [Example 2]( Figure 7 to Figure 10 )

[0067] Figure 7 It is a perspective view showing the part from the leg part 21 to the lower side including the holding mechanism 19 which is the main part of the printing apparatus 1 of this Example. also, Figure 8 It is a side view of the holding mechanism 19 which is the main part of the printing apparatus 1 of this embodiment. also, Figure 9 as well as Figure 10 It is a side view of the holding mechanism 19 which is the main part of the printing apparatus 1 of this Example, and shows the state which made the position of the rail part 20 in the direction Z different. here, Figure 7 to Figure 10 In this case, it is a diagram showing a part of the structure is omitted, and it is a diagram showing a part of the component parts.

[0068] In addition, in the printing apparatus 1 of this Example, the structure other than the part from the leg part 21 to the lower side is the same structure as that of the printing apparatus...

Abstract

According to the present invention, the posture of the holding portion capable of holding the roll-shaped medium is held with high precision. The printing device (1) includes: a printing unit (4) that prints on a medium (M) conveyed in a conveying direction (A); The direction (B) is formed; the holding part (17) is installed on the track part (20), and can hold the medium (M) in the shape of a roll, and the track part (20) has at least as The polyhedron of the first track surface (20c), the second track surface (20d) and the third track surface (20e) of the plane in the width direction (B), the holding part (17) has a The first abutting portion (24) abutting against the second track surface (20d), the second abutting portion (25) abutting against the second track surface (20d), the third abutting portion (26) abutting against the third track surface (20e) .

Description

technical field [0001] The present invention relates to a printing device. Background technique [0002] Conventionally, various printing devices have been used. Among them, there is a printing device that holds a roll-shaped medium by a holding portion and prints on a medium conveyed from the holding portion, or a printing device that can wind up the printed long medium into a roll. A printing apparatus having a holding section capable of holding a medium in a roll shape, such as a printing apparatus with a cylindrical holding section. [0003] For example, Patent Document 1 discloses a recording apparatus (printing apparatus) including a holder portion as a holding portion. [0004] The holding portion capable of holding the roll-shaped medium needs to move in the width direction intersecting with the conveying direction of the medium along with the attachment and detachment of the medium. In a conventional printing apparatus such as the recording apparatus of Patent Do...
