[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] like Figures 1 to 5 As shown, an embodiment of the utility model provides a device housing, which includes a housing 10 and a cover 20. The housing 10 has an installation space, and the installation space is used to install the printer 01. The cover 20 can be movably arranged on the housing 10, and the cover 20 cooperates with the housing 10 to form a closed space for the device housing, and the printer 01 is located in the closed space. The cover 20 is provided with a paper outlet 201, and the paper outlet 201 penetrates the cover 20. The cover 20 is also provided with a guide structure, which is arranged on the inner surface of the cover 20, and the guide structure is used to guide the paper of the printer 01 so that the paper extends out from the paper outlet 201.

[0038] By applying the technical solution of the utility model, after the printer 01 is installed in the device housing, when printing is required, the paper is extended from the paper outlet 011 and the paper outlet 201 of the printer 01 to the outside of the device housing. Specifically, after the end of the paper is extended from the paper outlet 011 of the printer 01, under the guiding action of the guide structure, the end of the paper is extended from the paper outlet 201 on the cover body 20 to the outside of the device housing. The setting of the guide structure can guide the output process of the paper, so that the end of the paper can smoothly enter the paper outlet 201, reduce the possibility of the paper curling in the device housing, and improve the smoothness of the printing process. Compared with the traditional technical solution, the setting of this solution can guide the end of the paper printed by the printer 01 during the extension process, guide the end of the paper to smoothly penetrate into the paper outlet 201 on the cover body 20, reduce the possibility of the end of the paper curling in the device housing and unable to extend from the paper outlet 201, and improve the smoothness of the printing process.

[0039] like Figure 2 and Figure 3 As shown, in the embodiment of the present scheme, the guide structure includes a guide groove 202, which is arranged on the inner surface of the cover body 20, and the extension direction of the guide groove 202, the paper outlet 201 and the paper outlet 011 of the printer 01 is the same, and the guide groove 202 is arranged on one side of the extension direction of the paper outlet 201 and is connected to the paper outlet 201; the guide groove 202 has a guide slope 2021, and along the direction from the guide slope 2021 to the paper outlet 201, the distance between the guide slope 2021 and the outer surface of the cover body 20 gradually decreases, and the projection of the paper outlet 011 of the printer 01 on the cover body 20 is located on the guide slope 2021. The projection of the paper outlet 011 of the printer 01 on the cover 20 is exactly located on the guide slope 2021. When the end of the paper extends from the paper outlet 011 of the printer 01, the end of the paper first contacts the guide slope 2021. Under the guidance of the guide slope 2021, the correct direction and shape can be maintained during the entire process of paper output, reducing the possibility of paper curling or jamming. The setting of the guide groove 202 has a simple structure and is easy to process.

[0040] It can be understood that the side of the guide slope 2021 of the guide groove 202 close to the outer surface of the cover body 20 is connected to the side wall of the paper outlet 201. In this way, the end of the paper maintains an upward tilting trend in the process of extending outward along the guide slope 2021 until the end of the paper touches the side wall of the paper outlet 201 away from the guide groove 202, and then the end of the paper extends toward the top surface of the cover body 20 along the paper outlet 201.

[0041] In the embodiment of this solution, the cross-sectional area of ​​the paper outlet 201 gradually decreases along the direction from the inner surface to the outer surface of the cover body 20. This arrangement enables the end of the paper to have a tendency to move toward the outer surface of the cover body 20 after contacting the paper outlet 201, further improving the smoothness of the paper extending out.

[0042] Furthermore, the cover 20 is detachably connected to the housing 10. This arrangement facilitates the installation of the printer 01 and other components inside the housing 10.
