The printing apparatus includes a first holder (3) for holding a roll-shaped medium (R), and the first holder (3) includes: a base (4); and a spindle (41) supported on the base (4), and the roll-shaped medium (R) is fixed by moving in the axial direction; the split nut part (54) is provided on the base (4) and can be divided into two; bolts (42), which moves the main shaft (41) in the axial direction; the handle (45), which makes the bolt (42) rotate; (54) In the closed state, the bolt (42) is screwed together, the bolt (42) rotated by the handle (45) is moved in the axial direction, and the split nut part (54) is in the open state. )freed.

Description

technical field [0001] The invention relates to a printing device. Background technique [0002] Conventionally, there has been known a large-scale printing device configured in a so-called roll-to-roll (roll-to-roll) system in which a roll-shaped A recording medium is supplied as a roll medium, and the printed recording medium is wound into a roll and collected. Such a printing device includes a medium support unit that supports the roll medium from both sides. For example, Patent Document 1 discloses a printing device in which a user rotates a handle provided on one side of the roll medium holder device (medium support unit) to move from one side to the other side. A printing device that presses a roll medium to fix the roll medium. [0003] However, in the printing device of Patent Document 1, when replacing the roll medium, the user needs to turn the handle in the opposite direction to that of the installation to return the medium support portion to the initial state....
