Claims (6)

1. A cartridge for housing therein a core around which a tape-like medium is wound in a roll, The cartridge includes, in order from the inside of the cartridge, the core, a spacer, an elastic member receiving portion, an elastic member, and one surface constituting the outer surface of the cartridge, The elastic member presses the core in the width direction of the medium through the elastic member receiving portion.
2. The cartridge of claim 1, wherein the cartridge comprises a housing, The elastic member receiving portion, the core, and the spacer are surrounded by the elastic member receiving portion, the core, and the spacer in a state deformed by the pressing of the elastic member.
3. The cartridge of claim 2, wherein the cartridge comprises, The elastic member is restricted to a position inside the outer periphery of the gap in a plane parallel to the surface.
4.A cartridge according to any one of claim 1 to 3, The elastic member is a leaf spring formed in a ring shape in a plane parallel to the surface.
5. The cartridge of claim 4, wherein the cartridge comprises a housing, In a plane parallel to the face, the centre of the elastic member and the centre of the core are both on a coaxial line.
6. A method for manufacturing a cartridge in which a core of a medium in a roll form is housed, the medium being wound in a tape form, The core is rotatably supported on the inner side constituting one of the outer surfaces of the cartridge, An elastic member receiving portion and an elastic member are mounted in this order from the spacer side between a spacer provided on the side surface of the core in the width direction of the medium and the inner surface of the case, so that the elastic member presses the core in the width direction of the medium through the elastic member receiving portion.

Description

Cartridge and method for manufacturing cartridge Cross-reference to related applications The present application claims priority from Japanese patent application No. 2024-193437, filed on 5/11/2024. Throughout this specification, reference is made to and reference is made to the specification, claims, and drawings of Japanese patent application No. 2024-193437. Technical Field The present disclosure relates to a cartridge (cartridge) that houses a rolled medium and a method of manufacturing the cartridge. Background Japanese patent application laid-open publication No. 2019-151063 discloses a printing apparatus in which a medium in a roll form (for example, a tape as a printing medium) is accommodated in a cassette, and a predetermined process (for example, printing) is performed on the medium while the medium is fed out from the cassette. In order to properly process the medium, it is necessary to convey the medium fed out from the cassette without being inclined. As a countermeasure, in the cartridge, a force for pulling out the medium from the core is stabilized by applying a load by pressing the core around which the medium is wound in the width direction of the medium by a biasing member such as a ring spring. However, since the force applied by the urging member to press the core is liable to vary, there is a problem in that the medium may travel obliquely when the medium is conveyed. The present disclosure has been made to solve the problems in such a situation, and an object of the present disclosure is to suppress the oblique travel of a medium when the medium is conveyed from a cassette. Disclosure of Invention A cartridge according to an aspect of the present disclosure includes a core in which a medium in a tape form is wound in a roll, the core, a spacer, an elastic member receiving portion, an elastic member, and one surface of an outer surface constituting the cartridge in this order from an inner side of the cartridge, the elastic member pressing the core in a width direction of the medium through the elastic member receiving portion. In one embodiment of the present disclosure, a method for manufacturing a cartridge that accommodates a core around which a medium in a tape form is wound in a roll is provided, wherein the core is rotatably supported on the inner side of one of outer surfaces constituting the cartridge, and an elastic member receiving portion and an elastic member are mounted in this order from the spacer side between a spacer provided on a side surface of the core in a width direction of the medium and the inner surface of the cartridge so that the elastic member presses the core in the width direction of the medium through the elastic member receiving portion. Drawings Fig. 1 is a perspective view of the cartridge in an exploded state. Fig. 2 is a perspective view of the cartridge in a completed state. Fig. 3 is a plan view showing the internal structure of the cartridge. Fig. 4 is a cross-sectional view of the holding structure of the tape roll before the cover is mounted to the base member of the cartridge. Fig. 5 is a cross-sectional view of a holding structure of the tape roll in a state where the cover is mounted on the base member of the cartridge. Fig. 6 is a graph showing the experimental results of carrying a belt using the cassette of the example and the cassette of the comparative example. Detailed Description In the embodiment described below, the cartridge 10 (tape cartridge) for housing the tape T, which is a medium (print medium) printed by a printing apparatus, is applied as an example of a cartridge for housing a core in which a tape-like medium is wound into a roll. The X-axis direction, the Y-axis direction, and the Z-axis direction shown in each figure are directions perpendicular to each other. The Z-axis direction is the thickness direction of the cartridge 10, and is the width direction of the belt T in the belt shape. The cartridge 10 has a base member 11 and a cover 12 mounted to the base member 11. The base member 11 and the cover 12 are assembled (see fig. 2 and 5) so as to be movable in the Z-axis direction from a separated state (see fig. 1 and 4), and the assembled base member 11 and cover 12 constitute the outer surface of the box 10. The base member 11 has a bottom surface portion 11a located on the-Z direction side and a side surface portion 11b protruding from the outer edge of the bottom surface portion 11a toward the +z direction side, and the +z direction side on the opposite side of the bottom surface portion 11a is opened. The cover 12 has an upper surface 12a, and the upper surface 12a is attached to the front end side of the side surface 11b to close the opening of the base member 11 in the +z direction. That is, the upper surface portion 12a of the cover 12 is one surface (+z-direction side surface) of the outer surface constituting the cartridge 10. The base member 11 has a plurality of fitting holes 11c open toward the +z direction
