[0030] This invention proposes a self-service printer.
[0031] In embodiments of the present invention, such as Figures 1 to 5 As shown, the self-service printer includes a printer body 10 and an electronic control module 20.
[0032] In this embodiment, the printer body 10 is responsible for the actual printing function, such as printing documents and photos. The electronic control module 20 includes a first housing 21 and an information processing module. The first housing 21 is installed on one side of the printer body 10, and the information processing module is installed inside the first housing 21. The information processing module is responsible for receiving printing instructions sent by the user, processing these instructions, and sending them to the printer body 10 to execute the printing task. The information processing module includes electronic components such as a processor, memory, and network module, and realizes the function of receiving, processing, and forwarding printing information.
[0033] This setup eliminates the need for an external computer. Users can send files directly to the printer's processing module via various methods (USB drive, network, mobile phone, memory card) to complete the printing process. This simplifies the operation and enhances convenience.
[0034] By directly mounting the electronic control module 20 onto the printer body 10, the cabinet is eliminated, which helps reduce the overall space occupied by the self-service printer. At the same time, it is equivalent to physically isolating the heat-generating electronic components from the heat source of the printer body 10, which helps with heat dissipation and stable operation. During maintenance, the first housing 21 can be removed directly without disassembling the structure of the printer body 10, which facilitates the maintenance and upgrading of the electronic control module 20, and will not affect the normal function of the printer body 10.
[0035] It is worth noting that, provided the communication protocols are compatible, the electronic control module 20 can be adapted to different models or brands of printer bodies 10.
[0036] In this embodiment, the electronic control module 20 further includes a control module, a permission management unit, and a print execution module. The control module is configured to receive user input to grant at least one other user permission to use the printer body 10 for printing. The permission management unit is used to store and maintain the permission information of the authorized user. The print execution module is used to query the permission management unit to verify whether the current user has printing permission before executing the printing task. If the user does not have permission, the printing operation will be refused.
[0037] Specifically, the control module is the "administrator center" or "permission configuration center". For example, when the self-service printer is used for rental and the lessee is the property management staff, the property management staff can grant printing permissions and set printing quotas for each tenant so that each tenant who is granted printing permissions can use the self-service printer, while non-tenants cannot use it, thus preventing unauthorized printing.
[0038] Furthermore, the electronic control module 20 also includes a print data monitoring unit and a data statistics unit. The print data monitoring unit is connected to the print execution module and is used to monitor and record the print usage data of the authorized user who triggered the print task when the print execution module executes the print task. The data statistics unit is connected to the print data monitoring unit and the access control unit and is used to associate and store the print usage data recorded by the print data monitoring unit with the corresponding user's record in the access control unit to count the print usage of each authorized user.
[0039] Specifically, property staff can use the printing data recorded by the printing data monitoring unit to know the printing usage of each authorized rental unit, thereby making accurate charges. At the same time, they can also use the recorded usage data to predict the consumption rate of consumables for each tenant, accurately arrange replenishment time, and avoid service interruptions.
[0040] The technical solution of this invention involves mounting a first housing 21 on the side wall of the printer body 10 and housing the information processing module inside the first housing 21. The first housing 21 protects the information processing module. The information processing module is responsible for receiving print commands sent by the user and sending them to the printer body 10 to execute the print task. This setup eliminates the need for an external computer. Users can send files to the information processing module on the printer via various direct methods, such as USB flash drives, networks, mobile phones, or memory cards, to complete the printing process. This simplifies the operation process and improves convenience. Furthermore, mounting the electronic control module 20 on the outside of the printer body 10 effectively isolates the heat-generating electronic components from the heat source of the printer body 10, which helps with heat dissipation and stable operation, while also facilitating subsequent maintenance and upgrades.
[0041] In some embodiments, the first housing 21 has a plurality of heat dissipation holes on the side opposite to the printer body 10. These holes are spaced apart from each other, and each hole connects to the interior of the first housing 21. Specifically, there are at least two heat dissipation holes, allowing heat from inside the first housing 21 to escape and improve the heat dissipation efficiency of the electronic control module 20. For example, the number of heat dissipation holes can be two, three, four, or more. Optionally, a rainproof portion is provided at the heat dissipation hole to prevent liquid from flowing into the first housing 21 through the hole. Furthermore, in other embodiments, no heat dissipation holes are provided on the first housing 21.
[0042] In some embodiments, the printer body 10 has a plurality of spaced storage cavities in the height direction. Each storage cavity has a pull-out opening on the front side of the printer body 10, and each storage cavity is detachably fitted with a paper tray 11 through the corresponding pull-out opening. The self-service printer also includes a blocking member 50 and a locking assembly. The blocking member 50 is located on the front side of the printer body 10 and extends along the height direction of the printer body 10 to limit the plurality of paper trays 11. The blocking member 50 has a limiting position on the front side of the printer body 10 and a release position away from the limiting position. When in the limiting position, the locking assembly is connected to the blocking member 50 to fix the blocking member 50 in the limiting position.
[0043] Specifically, there are at least two storage cavities, and the number of paper trays 11 corresponds to the number of storage cavities. Each storage cavity is used to accommodate an independent paper tray 11. Each paper tray 11 can be used to store different sizes of paper, such as A4, A3, photo paper, etc., for easy classification and management.
[0044] The blocking member 50 is installed on the printer body 10, located on the front side of multiple paper trays, extending along the height direction and covering the pull-out area of multiple storage cavities. When in the limited position, the blocking member 50 physically blocks the paper tray 11 to prevent unauthorized users from pulling out the paper tray 11 or taking paper at will. The blocking member 50 is fixed by the locking component to ensure that it cannot be moved at will. When in the released position, the blocking member 50 moves away from the front side, that is, the blocking member 50 releases the limitation on the paper tray 11, at which time the paper tray 11 can be pulled out to replenish or take out paper.
[0045] In some embodiments, the self-service printer further includes a connector 60, which is mounted on the side of the printer body 10. The shield 50 includes a shield 51 and a connecting plate 52 connected to each other. The shield 51 and the connecting plate 52 are perpendicular to each other. The connecting plate 52 is hinged to the connector 60. The shield 51 is located on the front side of the printer body. In the limited position, the locking component is connected to the shield 51.
[0046] Specifically, the connector 60 is fixed to the side of the printer body 10, serving as a support base for the shield 50 and providing a hinge point, allowing the shield 51 to rotate. This ensures that the shield 50 can stably switch between the limited position and the released position. In the limited position, the shield 51 prevents the paper tray 11 from being accidentally pulled out, acting as a physical barrier. The connecting plate 52 is vertically connected to the shield 51, forming an L-shaped structure. The connector 60 is hinged, allowing the entire shield 50 to rotate around the hinge point. When it is necessary to open the paper tray 11, the administrator releases the locking assembly, rotates the shield 51 to open to the side, and releases the limitation on the paper tray 11. At this time, the paper tray 11 can be pulled out to replenish or retrieve paper.
[0047] In some embodiments, the locking assembly includes an electronic lock, which is located at the bottom of the printer body 10. The end of the baffle plate 51 near the electronic lock has a lock hole. The lock tongue of the electronic lock is inserted into the lock hole to fix the baffle plate 51 in a limited position. The electronic lock is electrically connected to the electronic control module 20, which is used to control the opening and closing of the electronic lock.
[0048] Specifically, the electronic lock needs to be unlocked before the obstruction 50 can be opened. This design prevents others from easily accessing the obstruction 50. The unlocking method of the electronic lock can be selectively configured. In one embodiment, the user can unlock the lock on a mobile phone or on the display screen 40. It is worth noting that when unlocking via the display screen 40, a password must be entered first.
[0049] In some embodiments, the self-service printer further includes a cover plate 70, which covers the input interface of the printer body 10. Specifically, the cover plate 70 is used to cover the input interface of the printer body 10, such as a USB interface, SD card slot, Type-C interface, etc., to prevent the user from transmitting printing information to the printer body 10 for printing through the input interface.
[0050] In some embodiments, the self-service printer further includes a cover 71, which is disposed over the control panel of the printer body 10 to cover the control panel of the printer body 10. Specifically, the cover 71 is used to cover the control panel of the printer body 10 to prevent the user from making copies through the control panel.
[0051] In some embodiments, the self-service printer further includes a mounting bracket 30 and a display screen 40. The mounting bracket 30 is connected to the first housing 21, and the display screen 40 is mounted on the side of the mounting bracket 30 facing the printer body 10 and electrically connected to the electronic control module 20. The display side of the display screen 40 faces the front of the printer body 10. Specifically, the display screen 40 can be used to display printing options, status, prompts, operation instructions, etc. When the self-service printer is idle, the display screen 40 can be used to play advertisements and publish prompts, such as weather information, further enriching the functions of the self-service printer, enhancing its commercial value, and improving its market competitiveness. Optionally, the display screen 40 is a touch-screen display screen for easy user operation.
[0052] In some embodiments, the mounting bracket 30 is provided with a plurality of first mounting holes 34 and a plurality of second mounting holes 35. The plurality of first mounting holes 34 are spaced apart from each other, and the plurality of second mounting holes 35 are all located on the outer periphery of the plurality of first mounting holes 34 and are also spaced apart from each other. Specifically, the plurality of first mounting holes 34 are used to adapt to the installation of small-sized display screens 40, that is, the plurality of first mounting holes 34 correspond one-to-one with the mounting holes on the back of small-sized display screens 40. The plurality of second mounting holes 35 are used to adapt to the installation of large-sized display screens 40, and the plurality of second mounting holes 35 correspond one-to-one with the mounting holes on the back of large-sized display screens 40. In this way, when the size of the display screen 40 to be installed is small, the operator can install it using the first mounting holes 34, and when the size of the display screen 40 to be installed is large, the operator can install it using the second mounting holes 35, so that the mounting bracket 30 can adapt to display screens 40 of different sizes and meet the usage needs of different users.
[0053] In some embodiments, the mounting bracket 30 includes a mounting shell 32 and a mounting plate 33. The mounting shell 32 is hollow to form a wiring channel. The mounting shell 32 has an opening on the side away from the display screen 40 and multiple through holes on the side facing the display screen 40. Each through hole corresponds to an interface of the display screen 40. The opening connects to the wiring channel. The top of the first shell 21 has a wiring through hole. The wiring channel connects to the interior of the first shell 21 through the wiring through hole. The mounting plate 33 covers the opening.
[0054] Specifically, the cable routing channel is used to accommodate power cables, data cables and other cables of the display screen 40. Multiple through holes correspond to the interfaces of the display screen 40, such as HDMI, USB, power interface, etc. Cables can pass through these holes to connect to the display screen 40. The mounting plate 33 is covered by the opening and is used to open and close the opening to facilitate the installation, replacement or maintenance of internal cables.
[0055] In practice, the power and signal cables of the display screen 40 need to be connected from the electronic control module 20 to the display screen 40, i.e., the cables inside the first housing 21. For example, video signal cables and power cables pass through the top wiring hole of the connection part 211, enter the wiring channel, and then pass through the through hole of the mounting housing 32 to connect to the corresponding interface of the display screen 40. After the connection is completed, the mounting plate 33 closes the opening to completely hide the cables, avoiding the risk of mess or damage caused by exposure, and reducing the entry of dust or liquid into the wiring channel. Optionally, a sealing ring is provided between the mounting plate 33 and the periphery of the opening.
[0056] In some embodiments, the top of the first housing 21 is provided with a connecting portion 211, a wiring through hole is provided on the top of the connecting portion, the mounting bracket 30 is hinged to the connecting portion 211, and the mounting bracket 30 is provided with an ear 31 on at least one side of one end facing the connecting portion 211. The mounting bracket 30 has a vertical state and a retracted state that closes towards the connecting portion 211 from the vertical state. In the vertical state, the ear 31 is located on the side of the connecting portion 211 and is connected to the connecting portion 211 by a locking member.
[0057] Specifically, in the vertical position, the lugs 31 of the mounting bracket 30 move to the side position of the connecting part 211. At this time, the mounting bracket 30 is firmly fixed by a locking element (such as a screw, bolt, quick-release pin, etc.) passing through the hole in the lug 31 and connecting to the corresponding hole or structure on the side of the connecting part 211, preventing it from shaking or accidentally closing during user operation.
[0058] During transport, the locking mechanism is released from the connection between the lug 31 and the connecting part 211. The mounting bracket 30 folds forward around the hinge point toward the printer body 10, bringing the display screen 40 close to the printer body 10, thereby reducing the overall space occupied by the device. Moreover, in the folded state, the display side of the display screen 40 faces the printer body 10, which also helps to reduce the risk of accidental collisions or scratches.
[0059] This allows the display screen 40 to be folded up close to the printer body 10 during transport, significantly reducing the space occupied by the device, thereby increasing the loading rate and reducing transportation costs. When the printer needs to be used, the mounting bracket 30 can be rotated to a vertical position and firmly secured with locking devices, ensuring that the entire display screen 40 support structure is very stable and will not wobble when the user operates the screen, thus improving the user experience.
[0060] Furthermore, the mounting bracket 30 has ears 31 on both sides of the end facing the connecting portion 211. In the vertical state, the connecting portion 211 is located between the two ears 31, and each ear 31 is connected to the connecting portion 211 by a locking member. Specifically, in the vertical state, the connecting portion 211 is inserted between the two ears 31 of the mounting bracket 30, forming a sandwich structure. This connection between the two ears 31 and the connecting portion 211 helps to improve the stability of the mounting bracket 30 and further prevents the mounting bracket 30 from shaking. In addition, in other embodiments, the end of the mounting bracket 30 facing the connecting portion 211 has ears 31 on only one side.
[0061] In some embodiments, the self-service printer further includes a power module 80, which includes a second housing 81 and an energy storage power supply 82. The second housing 81 is mounted on the side of the self-service printer, and the energy storage power supply 82 is mounted inside the second housing 81 and electrically connected to the printer body 10.
[0062] Specifically, the energy storage power supply 82 is used to supply power to the printer body 10 in the event of a power outage, so as to meet the printing needs in the event of a power outage.
[0063] Furthermore, the power module 80 also includes a transformer module 83, which is connected between the electrical connection interface and the printer body 10. The transformer module 83 is used to change the voltage to a suitable operating voltage for the printer body 10, ensuring that the printer body 10 can operate safely and stably.
[0064] In some embodiments, the self-service printer is provided with a plurality of casters 90 at its bottom, which are distributed at intervals along the circumference of the self-service printer. This facilitates the movement of the printer body 10 and reduces the difficulty of transporting the self-service printer.
[0065] In this application, the cover 71, cover plate 70, connector 60, shield 50, first housing 21 and second housing 81 are all provided with multiple mounting holes. The multiple mounting holes on the cover 71, cover plate 70, connector 60, shield 50, first housing 21 and second housing 81 are all opened according to the screw holes at the corresponding positions of the printer body 10. In this way, when installing the cover 71, cover plate 70, connector 60, shield 50, first housing 21 and second housing 81, no additional fixing structure is required, that is, the overall structure of the printer body 10 will not be damaged, and non-destructive installation can be achieved.
[0066] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
