Thus, the statements "in one embodiment", "in some embodiments", "in other some embodiments", "in still other embodiments" etc. that appear in different places in this specification do not necessarily all refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "comprising", "including", "having" and their variants all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0048] In the related art, a receipt printer includes a printer core and a roll of printing paper, and the storage space required for the roll of printing paper is relatively large, resulting in that the receipt printer is usually difficult to be adapted to a relatively small cash register bracket. To solve the above technical problems, the embodiments of the present utility model provide a paper bin structure for a receipt printer. Specifically:

[0049] A paper bin structure for a receipt printer is arranged on a bracket and includes a paper bin body, and the paper bin body is in a whistle shape; the bracket includes a side plate and a bottom plate;

[0050] One end of the side plate is obliquely connected to the bottom plate and forms an included angle space with the bottom plate;

[0051] The paper bin body is arranged in the included angle space, and the shape of the paper bin body fits the included angle space;

[0052] One side of the paper bin body is fixed to the side plate.

[0053] As can be seen from the above description, the beneficial effects of the present utility model are as follows: The paper bin body of the receipt printer is arranged in the included angle space between the support side plate and the bottom plate, and the shape of the paper bin body is set to fit the included angle space, while reducing the volume of the paper bin, ensuring the accommodation space for the paper roll. One side of the paper bin body is fixed to the side plate to ensure that the paper bin body fits the side plate and avoid the existence of gap space, thereby realizing the rational use of the limited space between the side plate and the bottom plate to assemble the paper bin, enabling the receipt printer to adapt to a small-volume support.

[0054] In an embodiment of the present application, the paper bin body is in a whistle shape;

[0055] The planar side of the paper bin body is fixed to the side plate;

[0056] A first window is provided on the planar side of the paper bin body;

[0057] A second window is provided in the overlapping area between the side plate and the first window.

[0058] As can be seen from the above description, by providing a first window on the paper bin body and a second window in the corresponding area between the side plate and the first window, an open channel is formed between the paper bin body and the outside through the side plate, realizing the assembly of the paper roll in the paper bin without occupying the included angle space of the support.

[0059] In an embodiment of the present application, it further includes a paper bin cover;

[0060] One side of the paper bin cover is rotatably connected to the edge of the first window;

[0061] The shape and size of the paper bin cover are the same as those of the second window.

[0062] As can be seen from the above description, by providing the paper bin cover, the sealing performance of the paper bin body is ensured, and at the same time, the paper bin cover is rotatably connected to the paper bin body, facilitating the control of the opening and closing of the first window.

[0063] In an embodiment of the present application, a U-shaped notch is provided at the edge of the paper bin cover opposite to the rotatable connection, so that a slit is formed when the paper bin cover is closed with the second window.

[0064] As can be seen from the above description, by providing a U-shaped notch at the paper bin cover, a slit is formed when the paper bin cover is closed with the second window, serving as the paper outlet for the printing paper, eliminating the need for an additional paper outlet space and effectively simplifying the paper bin structure.

[0065] In an embodiment of the present application, a paper guiding member is provided near the U-shaped notch of the paper bin cover;

[0066] There is a gap space between the paper guide component and the U-shaped notch, and the gap space is used for the paper cutting blade to cut paper and reserve a cutting space.

[0067] As can be seen from the above description, by arranging a paper guide component at the U-shaped notch of the paper bin cover to guide the printing paper to be discharged from the U-shaped notch, the space on the paper bin cover is reasonably utilized to arrange the component, and excessive paper bin space is avoided from being occupied. At the same time, a paper cutting blade is arranged in the gap space to provide sufficient activity space for the paper cutting blade, so as to facilitate paper cutting.

[0068] In one embodiment of the present application, the paper guiding member includes a paper guiding platform and a paper guiding roller;

[0069] One side of the paper guide platform is fixed to the paper bin cover near the U-shaped notch;

[0070] The paper guide roller is arranged on the other side of the paper guide platform, and the straight line where the rotation axis of the paper guide roller is located is parallel to the slit.

[0071] It can be seen from the above description that by setting a paper guide platform to guide and support the printing paper to be discharged from the U-shaped notch, and setting a paper guide roller to reduce the friction of the printing paper, it is convenient to transport the printing paper.

[0072] In one embodiment of the present application, an extension platform is provided between the U-shaped notch and the paper guiding member, and the extension platform is perpendicular to the paper bin cover.

[0073] It can be seen from the above description that by providing an extension platform at the U-shaped notch to receive the printing paper, the paper output process is smoother and the problem of paper jam is avoided.

[0074] In one embodiment of the present application, a first rubber roller is provided on the bottom side of the cavity wall of the paper bin body;

[0075] A second rubber roller is arranged on one side of the paper bin cover plate close to the paper bin body.

[0076] As can be seen from the above description, by arranging rubber rollers in the area where the paper bin body and the paper bin cover plate contact the paper roll, the friction of the paper roll during the rolling process is reduced, thereby ensuring a smooth paper discharging process.

[0077] In one embodiment of the present application, a third window is provided in an area of ​​the paper bin body corresponding to the paper guide member;

[0078] The third window is used to install the printing mechanism of the receipt printer.

[0079] It can be seen from the above description that by providing the third window, the printer mechanism can be assembled using the suspended space of the bracket side plate, thereby improving the utilization rate of the bracket accommodating space.

[0080] Another embodiment of the present utility model provides an electronic device, including the above paper bin structure for a receipt printer.

[0081] In an embodiment of the present application, the electronic device may be a cash register, a self-service terminal, a payment device, etc.

[0082] The paper bin structure for a receipt printer provided by the present utility model can be applied to scenarios such as a relatively small cash register bracket. The following is an illustration through specific embodiments:

[0083] Embodiment 1

[0084] As Figure 1 shown, a paper bin structure 1 for a receipt printer is arranged on a bracket 2 and includes a paper bin body 11. The bracket 2 includes a side plate 21 and a bottom plate 22; one end of the side plate 21 is obliquely connected to the bottom plate 22 and forms an included angle space with the bottom plate 22. The paper bin body 11 is arranged in the included angle space, and the shape of the paper bin body 11 fits the included angle space; one side of the paper bin body 11 is fixed to the side plate 21. Among them, the side plate 21 includes a first side plate 211 and a second side plate 212, and the first side plate 211, the second side plate 212 and the bottom plate 22 are sequentially connected end to end to form a triangular prism structure. An included angle space is respectively formed between the first side plate 211 and the bottom plate 22 and between the second side plate 212 and the bottom plate 22, and the paper bin body 11 is arranged in any one of the included angle spaces. Since the printing paper roll is cylindrical, in order to ensure the accommodation space of the printing paper roll and reasonably utilize the included angle space of the bracket 2, the shape of the paper bin body 11 can be correspondingly set as cylindrical, and at the same time, the connection between the first side plate 211 and the bottom plate 22 and the connection between the second side plate 212 and the bottom plate 22 are set as arc-shaped connections, so that the printing paper roll can fully fit the included angle space of the bracket 2.

[0085] As Figure 2 and Figure 3 shown, the paper bin body 11 is in a whistle shape, and the flat side of the paper bin body 11 is fixed to the side plate 21. A first window 111 is arranged on the flat side of the paper bin body 11; a second window 23 is arranged in the overlapping area of the side plate 21 and the first window 111. Among them, since the side surfaces of the cylinder are all curved surface structures, the stability of the paper bin body 11 cannot be guaranteed. Therefore, the paper bin body 11 is set in a whistle shape. While ensuring that the cavity of the paper bin body 11 can adapt to the shape of the printing paper roll 13, a plane is formed to fit the side plate 21 of the bracket 2 through this plane, thereby improving the stability of the paper bin body 11.

[0086] In some embodiments, a first threaded hole 1111 is provided at the edge of the first window 111, and a second threaded hole 231 is provided at the edge of the second window 23. Through the cooperation of the first threaded hole 1111, the second threaded hole 231 and the screw, the paper cassette body 11 is fixed to the side plate 21 of the bracket 2.

[0087] As Figure 4 shown, it further includes a paper cassette cover 12. The paper cassette cover 12 is arranged on the side of the side plate 21 away from the paper cassette body 11; one side of the paper cassette cover 12 is rotatably connected to the edge of the first window 111. The shape and size of the paper cassette cover 12 are the same as those of the second window 23. Among them, the paper cassette cover 12 is provided with an extension part 121, the extension part 121 is an arc structure, and one end of the extension part 121 is rotatably connected to the edge of the first window 111. By providing the extension part 121, it is ensured that the paper cassette cover 12 can achieve the maximum opening and closing angle, which is convenient for installing the paper roll 13.

[0088] As Figure 5 and Figure 6 shown, a U-shaped notch 122 is provided at the edge of the paper cassette cover 12 opposite to the rotatable connection, so that a slit is formed when the paper cassette cover 12 is closed with the second window 23. A paper guiding member 123 is provided near the U-shaped notch 122 of the paper cassette cover 12. There is a gap space 124 between the paper guiding member 123 and the U-shaped notch 122, and the gap space 124 is used to reserve a cutting space for the cutting blade to cut the paper. An extension platform 125 is provided between the U-shaped notch 122 and the paper guiding member 123, and the extension platform 125 is perpendicular to the paper cassette cover 12. Among them, the paper cassette cover 12 and the extension platform 125 are of an integrally formed structure.

[0089] As Figure 7 and Figure 8 shown, the paper guiding member 123 includes a paper guiding platform 1231 and a paper guiding roller 1232. One side of the paper guiding platform 1231 is fixed to the paper cassette cover 12 near the U-shaped notch 122. The paper guiding roller 1232 is arranged on the other side of the paper guiding platform 1231, and the straight line where the rotation axis of the paper guiding roller 1232 is located is parallel to the slit. Among them, the paper guiding platform 1231 includes an inclined surface platform 1233, a partition plate 1234 and a fixing platform 1235. One side of the fixing platform 1235 is fixed to the paper cassette cover 12 near the U-shaped notch 122. The inclined surface platform 1233 is arranged on the other side of the fixing platform away from the paper cassette cover 12, and the inclined surface platform 1233 is perpendicular to the fixing platform 1235. The partition plate 1234 is arranged on the inclined surface platform 1233, and the partition plate 1234 is parallel to the fixing platform 1235. The gap above the gap between the partition plate 1234 and the fixing platform 1235 is used to arrange the paper guiding roller 1232. The inclined surface platform 1233 is used to guide the printing paper to be conveyed upward, and the partition plate 1234 is used to prevent the printing paper from passing through the gap between the paper guiding roller 1232 and the inclined surface platform 1233.

[0090] As Figure 8 and Figure 9 shown, a first rubber roller 112 is provided at the bottom side of the cavity wall of the paper bin body 11; a second rubber roller 126 is provided on the side of the paper bin cover 12 close to the paper bin body 11. Among them, a curved inner plate 127 is provided on the side of the paper bin cover 12 close to the paper bin body 11 to ensure that the cavity formed by the paper bin cover 12 and the paper bin body 11 is cylindrical, so as to adapt to the shape of the printing paper roll 13.

[0091] As Figure 9 and Figure 10 shown, a third window 113 is provided in the area of the paper bin body 11 corresponding to the paper guiding member 123; the third window 113 is used to install the printer core of the receipt printer. Among them, the printer core is used to control the movement of the paper guiding roller 1232 on the paper bin cover 12 and complete the printing task on the printing paper roll at the same time.

[0092] Embodiment 2

[0093] An electronic device includes a paper bin structure for a receipt printer in Embodiment 1. For example, the electronic device is a financial terminal device such as a cash register. During the process of assembling the printing paper roll to the paper bin body, first open the paper bin cover on the bracket, then pass the paper end of the printing paper roll around the paper guiding platform and the paper guiding roller, and pull it out from the U-shaped notch of the paper bin cover. After closing the paper bin cover to the second window on the bracket, the printing can be started. By fitting the included angle space between the paper bin body and the bracket and setting the first window of the paper bin body at the second window of the bracket, when the paper roll is assembled to the paper bin body, it does not need to occupy the space inside the bracket, thereby improving the space utilization rate inside the bracket.

[0094] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent transformations made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in related technical fields, are equally included in the patent protection scope of the present invention.
