With continued reference to fig. 1-2, the carbon ribbon support frame 200 is provided with a force receiving portion 201 at either end in the first direction, and when the carbon ribbon support frame 200 is mounted in the inner cavity 110, a force application space is provided below the force receiving portion 201, specifically, the force application space is located between the force receiving portion 201 and a cavity wall of the inner cavity 110, and the force application space is configured to allow a force application object to extend into the force application space and collide with the force receiving portion 201. Therefore, the user can extend into the force application space and prop against the force receiving portion 201 through the force application object, so as to apply force to the force receiving portion 201, and the disassembly and replacement of the carbon ribbon support frame 200 are completed. The force application object can be a finger or a plurality of columnar structures. Meanwhile, because the extending direction of the force receiving portion 201 forms an included angle with the second direction, the user can apply force to the force receiving portion 201 along the second direction, that is, apply force along the detaching direction of the carbon ribbon support 200, so that the detachment and replacement of the carbon ribbon support 200 can be completed with a smaller force. In addition, the axis of the carbon ribbon installed on the carbon ribbon support frame 200 is parallel to the first direction, and the stress portion 201 is disposed at any end of the carbon ribbon support frame 200 along the first direction, instead of one end of the carbon ribbon support frame 200 along the carbon ribbon conveying direction, so as to avoid interference with the printing medium and influence on normal conveying of the printing medium.

Optionally, the angle between the extending direction of the force receiving portion 201 and the second direction is 90 °, that is, the extending direction of the force receiving portion 201 is perpendicular to the second direction, it is understood that the larger the angle between the extending direction of the force receiving portion 201 and the second direction is, the smaller the force applied by the user to the force receiving portion 201 for disassembling the carbon ribbon supporting stand 200 is, and when the extending direction of the force receiving portion 201 is perpendicular to the second direction, that is, the angle is 90 °, the force applied by the user to the force receiving portion 201 is the smallest.

Optionally, the force receiving portion 201 has a contact surface on a side close to the force application space, and when the force application object is a finger, the finger directly contacts the contact surface, so that the contact surface is arc-shaped to adapt to the shape of the finger. In this embodiment, the force receiving portion 201 is in an inverted L shape and has two force receiving sides, so that the force application object can abut against the force receiving portion 201 along at least two directions. Alternatively, the two stress edges are in contact with the carbon ribbon support frame 200, so that the two stress edges can be mutually reinforced ribs, and the stress portion 201 is prevented from being deformed or broken due to stress, so that the connection structural strength between the stress portion 201 and the carbon ribbon support frame 200 is enhanced.

Optionally, the force-receiving portions 201 are provided in plurality, and part of the force-receiving portions 201 are located at one end of the carbon ribbon support frame 200 along the first direction, and the other part of the force-receiving portions 201 are located at the other end of the carbon ribbon support frame 200 along the first direction. Therefore, the force-applying objects can respectively abut against the force-receiving portions 201, for example, the force is applied to the force-receiving portions 201 by different fingers of a user, so as to further facilitate the disassembly of the carbon ribbon support frame 200.

Specifically, the following scheme may be adopted, where an opening is formed on a side of the force receiving portion 201 facing the force application space, and the opening of the force receiving portion 201 located at one end of the carbon ribbon support frame 200 is facing away from the opening of the force receiving portion 201 located at the other end of the carbon ribbon support frame 200. Therefore, the force application objects can be abutted against the force receiving portions 201 at two ends of the carbon ribbon support frame 200 along different directions, the force application objects can apply force along the second direction, and the force application objects can apply force with opposite directions to the force receiving portions 201, so that the two ends of the carbon ribbon support frame 200 along the first direction are balanced in force.

In another alternative, an opening is formed on one side of the force receiving portion 201 facing the force application space, two force receiving portions 201 are respectively arranged at two ends of the carbon ribbon support frame 200 along the first direction, and the openings of the two force receiving portions 201 at the same end face away from each other. Therefore, a user can act on the two stress parts 201 at the same end through two fingers respectively, and in addition, the opening directions of the two stress parts 201 at the same end are deviated, so that the force application of the user is facilitated.

Alternatively, two schemes may be combined, specifically, two force receiving portions 201 are disposed at two ends of the carbon ribbon support frame 200 along the first direction, one of the two force receiving portions 201 at the same end is disposed near the axis of the winding shaft, and the other is disposed near the axis of the releasing shaft. In addition, the opening orientations of the two stress portions 201 at the same end are opposite, and the opening orientations of the stress portions 201 at different ends are also opposite. So that the stress parts 201 at the two ends of the carbon ribbon support frame 200 are symmetrically arranged, the two fingers of the hands of a user can apply force simultaneously while the appearance is neat, and the stress of the carbon ribbon support frame 200 is balanced.

Optionally, since the force-receiving portion 201 is disposed on the carbon ribbon support 200, it may interfere with the normal paper feeding of the printer, and in order to reduce the influence on the paper feeding of the printer as much as possible, the force-receiving portion 201 is disposed at the end of the carbon ribbon support 200, so that a user can more easily insert a finger into the force-applying space to contact with the force-receiving portion 201 when taking and placing the carbon ribbon support 200.
