5. 5. A printing device as claimed in claim 2, wherein, The lower wall is less rigid than the upper wall.
6. 6. A printing device as defined in claim 5, wherein, The lower wall is formed from a different raw material than the upper wall.
7. 7. A printing device as claimed in claim 1, wherein, The lower end portion is deformable in the up-down direction, The edge of the opening has a step part which overlaps the lower end part in a direction crossing the up-down direction in a state where the opening-closing cover is closed, The length of the step portion in the up-down direction is smaller than the deformation amount of the lower end portion.
8. 8. A printing device as claimed in claim 1, wherein, The lower end portion is deformable in the up-down direction, The edge of the opening has a step part which overlaps the lower end part in a direction crossing the up-down direction in a state where the opening-closing cover is closed, The length of the step portion in the up-down direction is greater than the deformation amount of the lower end portion.
9. 9. A printing device as claimed in claim 1, wherein, The edge of the opening has a step portion overlapping the lower end portion in the up-down direction in a state where the opening-closing cover is closed, The step portion is movable in the up-down direction.

Description

Printing device Technical Field The present invention relates to a printing apparatus. Background Conventionally, various printing apparatuses have been used. There is a printing apparatus having a structure in which an opening/closing cover is provided to be opened and closed in the up-down direction with respect to a housing. For example, patent document 1 discloses a liquid ejecting apparatus including a shield that can be opened and closed in the vertical direction. In a conventional printing apparatus including an openable cover that can be opened and closed in the vertical direction, when the openable cover is closed, the openable cover may be strongly closed by gravity, and there is a possibility that the openable cover collides with an opening of a casing strongly or a finger of a user or the like is pinched between the openable cover and the opening of the casing. That is, the user may need to take care with the opening and closing of the opening and closing cover, and the opening and closing of the opening and closing cover may become a load for the user. On the other hand, if a damper mechanism, a large spring mechanism with a strong elastic force, or the like is provided so that the open-close cover is gradually closed when the open-close cover is closed, there are cases of high cost, cases of a small space inside the open-close cover, and the like. Patent document 1 Japanese patent application laid-open No. 2020-104426 Disclosure of Invention The printing apparatus according to the present invention for solving the above-described problems is characterized by comprising a printing unit that prints on a medium, a housing that houses the printing unit and has an opening configured to be partially openable, and an opening/closing cover that covers the opening and opens and closes in the vertical direction, wherein the opening/closing cover has a side wall that extends in the vertical direction in a closed state, and at least one of a lower end portion of the side wall and an edge of the opening that faces the lower end portion in the vertical direction in the closed state is deformable. Drawings Fig. 1 is a schematic perspective view of a printing apparatus according to embodiment 1 of the present invention. Fig. 2 is a perspective view showing the periphery of the opening/closing cover of the printing apparatus of fig. 1, and is a view showing a state in which the opening/closing cover is fully opened. Fig. 3 is a perspective view showing the periphery of the opening/closing cover of the printing apparatus of fig. 1, as viewed from a different angle from fig. 2, and is a view showing a state in which the opening/closing cover is moved further in the closing direction than the state shown in fig. 2. Fig. 4 is a perspective view showing the periphery of the opening/closing cover of the printing apparatus of fig. 1, and is a view showing a state in which the opening/closing cover is moved further in the closing direction than the state shown in fig. 3.
