Embodiment 1
[0032] [Example 1]( Figure 1 to Figure 10 )
[0033] First, refer to figure 1 , the outline of the recording device 1 of the first embodiment will be described.
[0034] figure 1 It is a schematic perspective view of the recording device 1 according to this embodiment.
[0035] In addition, in figure 1 In , in order to make the structure easier to understand, some structural components are omitted for illustration.
[0036] Here, the X direction in the figure is a horizontal direction and is a direction in which the shaft portion 4 of the medium support device 2 extends, the Y direction is a horizontal direction and is a direction perpendicular to the X direction, and the Z direction is a vertical direction. In addition, in the following, the direction marked by an arrow is referred to as a + direction, and the direction opposite to the direction marked by an arrow is referred to as a − direction. For example, let the vertical upward direction be +Z direction, and let t...

Abstract
The invention relates to a medium support device and a recording device. The medium support device suppresses deformation of a support portion, which supports a roll body around which a sheet-like medium is wound, with respect to a shaft portion. A medium support device (2) is provided with a support unit (3) that supports a roll body (R) around which a sheet-like medium is wound; a shaft part (4)which constitutes a rotating shaft of the roll body (R) and to which the support part (3) is fixed; a drive unit (10), and a rotating part (4) for rotating the roll body (R) supported by the supportpart (3). The shaft part (4) and the support part (3) are fixed together using a metal plate (32) having a flat surface (32b) in which an insertion hole (32a) through which the shaft part (4) is inserted is provided, and the outer peripheral part (32c) of the metal plate (32) is restricted in the rotational direction of the roll body (R) with respect to the inner peripheral part (33a) of the support part (3).
Description
technical field [0001] The invention relates to a medium supporting device and a recording device. Background technique [0002] A wide variety of media support devices have been used heretofore. Among them, there is a medium support device that supports a roll body on which a sheet-shaped medium is wound. Various structures are disclosed as such a medium support device. [0003] For example, Patent Document 1 discloses a core tube holding device (medium support device) that supports a recording medium wound into a roll (a roll body wound with a sheet-like medium). The core tube holding device of Patent Document 1 includes: a flange portion (support portion) that supports a recording medium wound into a roll; and a shaft portion that constitutes the recording medium wound into a roll. axis of rotation and fix the flange. [0004] However, in such a conventional medium support device as disclosed in Patent Document 1, the support portion and the shaft portion are fixed by...
