[0031] The utility model provides a printer cabinet used for a self-service printer.

[0032] In the embodiment of the present utility model, Figures 1 to 7 As shown, the printer cabinet includes a cabinet body 10, and the cabinet body 10 is provided with an installation cavity 101 and a paper removal port 102 located on one side of the cabinet body 10, the paper removal port 102 is connected with the installation cavity 101, the installation cavity 101 is used for printer installation, and the paper removal port 102 is used to correspond to the paper output port of the printer.

[0033] In this embodiment, the printer cabinet also includes an electric control device, which is arranged in the installation cavity 101 and is used to connect with the printer installed in the installation cavity 101; that is, during installation, the printer is installed in the installation cavity 101, and the printer is connected to the electric control device, so that the user can control the printer to work through the electric control device, so that the paper outlet of the printer corresponds to the paper pick-up port 102 on the cabinet, so that the paper sent out from the paper outlet of the printer during printing can be sent to the paper pick-up port 102 for the user to take. Among them, the electric control device includes a circuit board and a controller, a communication module, etc. arranged on the circuit board. The specific structure of the electric control device can refer to the prior art, and the utility model will not repeat it one by one.

[0034] In some embodiments, a mounting position 11 and an inclined platform 12 are provided on the top of the cabinet 10, the mounting position 11 is close to the rear side of the cabinet 10, the inclined platform 12 extends from the mounting position 11 to the front side of the cabinet 10, and the inclined platform 12 gradually tilts downward in the direction close to the front side of the cabinet 10. Optionally, the printer cabinet further includes a display device 60, which is provided at the mounting position 11 and is electrically connected to the electronic control device. Specifically, when the printer cabinet is used for a self-service printer, the display device 60 can be used to display the working status of the printer, such as displaying standby, printing, fault status, etc.

[0035] The technical solution of the utility model is to set a mounting position 11 and a tilting platform 12 on the top of the cabinet 10, and make the mounting position 11 close to the rear side of the cabinet 10, and the tilting platform 12 extends from the mounting position 11 to the front side of the cabinet 10, and the tilting platform 12 gradually tilts downward in the direction close to the front side of the cabinet 10. In this way, the mounting position 11 is provided with a display device 60, and objects cannot be placed. Although the tilting platform 12 is vacant, its tilting design allows users to clearly know that if they place objects such as mobile phones on the tilting platform 12, the mobile phones will slide off the tilting platform 12, so that they will not place objects such as mobile phones on the tilting platform 12, which can prevent users from forgetting objects on the printer cabinet at any time. In addition, this can also prevent users from blocking the tilting platform 12, so that printing guidance and other contents can be set on the tilting platform 12 to facilitate users to use self-service printers.

[0036] In some embodiments, the tilt angle of the tilt platform 12 relative to the horizontal plane is not less than 20°, so that the tilt platform 12 can have a larger inclination, allowing users to clearly see the tilt design and prevent users from mistakenly placing a mobile phone on the tilt platform 12.

[0037] In some embodiments, the inclination angle of the inclined platform 12 relative to the horizontal plane is not greater than 45°. This setting can avoid the situation where the inclination angle of the inclined platform 12 is too large, causing the cabinet 10 to be too high or compressing the volume of the installation cavity 101, and avoid the space inside the inclined platform 12 being too low, so as to facilitate the use of the space inside the inclined platform 12.

[0038] In some embodiments, the inclination angle of the inclined platform 12 relative to the horizontal plane is not less than 20° and not greater than 45°, and can be specifically 20°, 22°, 25°, 28°, 30°, 32°, 35°, 38°, 40° or 45°.

[0039] In some embodiments, the inclined platform 12 is provided with a display position 121, and the display position 121 is used for installing a QR code device. Specifically, when used for a self-service printer, the QR code device is used to display a QR code corresponding to the self-service printer, so that the user can scan the QR code on site to connect to the self-service printer. Using the inclined platform 12 to set the display position 121 can not only improve the utilization rate of the inclined platform 12, but also effectively avoid the display position 121 from being blocked.

[0040] Among them, the specific structure of the QR code device can be various. For example, in some embodiments, the printer cabinet also includes a QR code display screen, and the QR code display screen is installed at the display position 121; this is convenient for real-time display or adjustment of the QR code, and is convenient for use according to actual needs.

[0041] In other embodiments, the display position 121 is provided with a light-transmitting plate and a light-emitting device disposed on the back of the light-transmitting plate, and the light-transmitting plate is used for pasting the QR code label. That is, the light-emitting device can provide backlight for the QR code label so that the user can clearly scan the QR code.

[0042] The specific structure of the display device 60 can be various. For example, in some embodiments, the display device 60 includes a display screen, which is installed at the installation position 11. In this way, more content can be displayed on the display screen for user use and maintenance personnel to view the status of the self-service printer.

[0043] In other embodiments, the display device 60 includes a plurality of status lights to indicate different printing states through different status lights. For example, the white status light can be turned on in the standby state, the green status light can be turned on when the printer is working, and the red status light can be turned on when the printer fails. On a self-service printer that has both a normal printer and a photo printer, the pink status light can be turned on when A4 paper is out of paper, and the purple status light can be turned on when photo paper is out of paper.

[0044] In some embodiments, the printer cabinet also includes an electronic lock and a cover 20. The electronic lock is arranged at the paper outlet 102 and is electrically connected to the electronic control device.

When the cover 20 covers the paper outlet 102, the electronic lock cooperates with the lock buckle 21 to lock the cover 20 at the paper outlet 102.

[0045] That is, when not in use, the lock buckle 21 can be locked by the electronic lock, thereby locking the cover 20 at the paper taking port 102, preventing the cover 20 from being opened and causing foreign matter to enter the paper taking port 102. When printing, the user can control the electronic lock to open through mobile phone software or applet, so that the user can open the cover 20 to take out the printed document.

[0046] In this embodiment, the cover plate 20 is a translucent plate (i.e., the transmittance is less than 90%), that is, the user can see the blurred shape of the object in the paper outlet 102 through the cover plate 20, but cannot see the specific content on the paper. For example, the transmittance of the cover plate 20 is less than 90%. Specifically, the transmittance of the cover plate 20 is between 50% and 90%, for example, 90%, 85%, 80%, 75% or 50%.

[0047] The technical solution of the utility model is to set a cover plate 20 and an electronic lock at the paper taking port 102 of the printer cabinet, and set a lock buckle 21 cooperating with the electronic lock on the inner side of the cover plate 20, so that when it is idle, the lock buckle 21 can be locked by the electronic lock, thereby locking the cover plate 20 at the paper taking port 102, preventing the cover plate 20 from being opened and causing foreign objects to enter the paper taking port 102, and also preventing the printed file from being taken away by others when the printing is completed but the printer has not yet arrived, which can improve the reliability of the printer cabinet. The cover plate 20 is set as a semi-transparent plate, which can not only allow users to distinguish whether there is paper in the paper taking port 102, but also prevent others from seeing the specific content on the paper, which is convenient to use and can also improve the confidentiality of the printed file.

[0048] In some embodiments, the printer cabinet further includes a cover plate 20, which is movably mounted at the paper outlet 102 to open or close the paper outlet 102.
