[0034] The present utility model provides a self-service printer.

[0035] In the embodiments of the present utility model, as Figures 1 to 7 shown, the self-service printer includes a cabinet 10, a first printing device (not shown in the figure), a second printing device (not shown in the figure), and a storage component 20.

[0036] The cabinet 10 is provided with an installation cavity 111. One side of the cabinet 10 is provided with a paper taking port 121, and the paper taking port 121 is communicated with the installation cavity 111. The first printing device and the second printing device are both installed in the cabinet 10, and the second printing device is located above the first printing device. As we know, the printing device is a device for printing documents or photos, and this device can refer to the prior art, and the present application will not elaborate on this one by one.

[0037] In this embodiment, the self-service printer further includes an electric control device, which includes an electric control component, a control circuit board and other circuit structures for controlling the operation of the first printing device and the second printing device.

[0038] Specifically, the first printing device and the second printing device can be respectively set as a black-and-white printing device and a color laser printing device, so as to meet the different printing needs of users. Of course, in other embodiments, the first printing device and the second printing device can also be set as two printing devices of the same type. In this way, when one of the first printing device and the second printing device fails, the printing operation can be carried out by the other one.

[0039] The storage component 20 has a storage channel 211 and a guiding channel 221 located above the storage channel 211. The receiving end of the storage channel 211 corresponds to the paper outlet of the first printing device, the sending end of the storage channel 211 corresponds to the paper taking port 121, the upper end of the guiding channel 221 corresponds to the paper outlet of the second printing device, and the lower end of the guiding channel 221 corresponds to the storage channel 211. That is to say, the storage channel 211 connects the paper outlet of the first printing device and the paper taking port 121, and the guiding channel 221 connects the paper outlet of the second printing device and the storage channel 211. That is, the paper printed by the first printing device can be sent from the paper outlet into the storage channel 211. After the paper printed by the second printing device is sent from the paper outlet to the guiding channel 221, under the action of gravity, the paper will fall into the storage channel 211 connected to the guiding channel 221. That is to say, the paper printed by either the first printing device or the second printing device will be stored in the storage channel 211, and the user can take out the paper printed by the first printing device or the second printing device from the storage channel 211 through the paper taking port 121.

[0040] The technical solution of the present utility model installs both the first printing device and the second printing device in the cabinet 10, and the second printing device is located above the first printing device. The storage component 20 has a storage channel 211 and a guiding channel 221 located above the storage channel 211. The receiving end of the storage channel 211 corresponds to the paper outlet of the first printing device, the sending end of the storage channel 211 corresponds to the paper taking port 121, the upper end of the guiding channel 221 corresponds to the paper outlet of the second printing device, and the lower end of the guiding channel 221 corresponds to the storage channel 211. To guide the paper sent out by the second printing device into the storage channel 211. In this way, the paper printed by the first printing device can be sent from the paper outlet into the storage channel 211, and the paper printed by the second printing device can be sent from the paper outlet into the guiding channel 221 and then fall into the storage channel 211 under the action of gravity. That is to say, the paper printed by either the first printing device or the second printing device can be stored in the storage channel 211, enabling the user to take out the paper printed by the first printing device or the second printing device from the storage channel 211 through the paper taking port 121. Compared with the method of setting a paper taking port 121 corresponding to each printing device on the cabinet 10, this can simplify the overall structure of the self-service printer and reduce the production and processing difficulty of the cabinet 10.

[0041] In some embodiments, the lower end of the guiding channel 221 is inclined relative to the bottom wall 212 of the storage channel 211. Specifically, after the paper printed by the second printing device is sent from the paper outlet into the guiding channel 221, since the lower end of the guiding channel 221 is inclined relative to the bottom wall 212 of the storage channel 211, the paper is inclined during the falling process. In this way, when the paper falls into the storage channel 211, the paper can be laid flat in the storage channel 211 to prevent the paper from standing in the storage channel 211 and the guiding channel 221.

[0042] Specifically, in some embodiments, the side wall of the guiding channel 221 facing the second printing device gradually extends obliquely in the direction of the storage channel 211. In another embodiment, a guiding plate is provided at the end of the lower end of the guiding channel 221, and the guiding plate extends obliquely.

[0043] In some embodiments, the bottom wall 212 of the storage channel 211 is provided with an avoidance groove 214, the avoidance groove 214 extends along the width direction of the storage channel 211, and the lower end of the guiding channel 221 faces the bottom wall 212 of the avoidance groove 214.

[0044] Specifically, the provision of the avoidance groove 214 increases the distance between the lower end of the guiding channel 221 and the bottom wall 212 of the storage channel 211. In this way, when the paper falls into the storage channel 211, the paper can be laid flat in the storage channel 211, preventing the paper from standing upright in the storage channel 211 and the guiding channel 221. Of course, in other embodiments, the bottom wall 212 of the storage channel 211 may not be provided with the avoidance groove 214.

[0045] In some embodiments, the width dimension of the guiding channel 221 is tapered in the direction approaching the storage channel 211. The side wall of the guiding channel 221 facing the second printing device gradually extends obliquely in the direction of the storage channel 211, so that the width dimension of the guiding channel 221 is tapered in the direction approaching the storage channel 211. This can reduce the occupied space of the guiding channel 221 and release the available installation space inside the cabinet body 10.

[0046] In some embodiments, the storage assembly 20 includes a paper storage structure 21 and a guiding structure 22. The paper storage structure 21 has a storage channel 211. A through hole 213 is provided on one side of the paper storage structure 21 facing the second printing device. The guiding structure 22 has a guiding channel 221, and the lower end of the guiding channel 221 is correspondingly arranged opposite the through hole 213.

[0047] Specifically, the paper storage structure 21 and the guiding structure 22 are integrally formed separately, and the paper storage structure 21 and the guiding structure 22 are assembled to form the storage assembly 20. This setting is beneficial to reducing the production and forming difficulty of the storage assembly 20 and reducing the production and manufacturing time. Of course, in other embodiments, the paper storage structure 21 and the guiding structure 22 are integrally formed.

[0048] Further, the lower end of the guiding structure 22 extends into the storage channel 211 through the through hole 213. Specifically, to avoid the gap between the lower end of the guiding channel 221 and the surface of the storage structure caused by the precision difference during the production and processing of the guiding structure 22, during the production and processing of the guiding structure 22, the overall length of the guiding structure 22 is increased so that the lower end of the guiding structure 22 extends into the storage channel 211 to ensure that the paper printed by the second printing device can fall into the storage channel 211 through the guiding channel 221. Of course, in other embodiments, the lower end of the guiding structure 22 abuts against the periphery of the through hole 213.

[0049] In some embodiments, the upper end opening of the guiding channel 221 is provided on the side of the guiding structure 22 facing the second printing device.

[0050] Specifically, the opening provided on the side corresponds to the paper outlet of the second printing device. That is to say, the paper printed by the second printing device can be directly sent from the paper outlet into the guiding channel 221. In this way, there is no need to additionally provide other connecting structures to convey the paper printed by the second printing device, which is beneficial to simplifying the overall structure of the self-service printer. Of course, in other embodiments, the upper opening of the guiding channel 221 is provided on the top surface of the guiding structure 22.

[0051] In some embodiments, the top surface of the guiding structure 22 is provided with a plurality of weight-reducing holes 222. Each weight-reducing hole 222 penetrates through the top surface of the guiding structure 22, and adjacent two weight-reducing holes 222 are spaced apart from each other.

[0052] Specifically, the number of the weight-reducing holes 222 is at least two. The overall structural weight of the guiding structure 22 is reduced through the weight-reducing holes 222, making the overall guiding structure 22 lighter and reducing the overall weight of the self-service printer. Exemplarily, the number of the weight-reducing holes 222 can be, but is not limited to: two, three, four, etc. Of course, in other embodiments, the top surface of the guiding channel 221 may not be provided with weight-reducing holes 222.

[0053] In some embodiments, the bottom wall 212 of the storage channel 211 has a receiving section 212a and a sending section 212b that are connected to each other. The receiving section 212a is arranged close to the paper outlet of the first printing device. The receiving section 212a gradually slopes downward in the direction close to the paper outlet of the first printing device, and one end of the receiving section 212a close to the paper outlet of the first printing device is lower than the paper outlet of the first printing device. The sending section 212b is arranged close to the paper taking port 121 and gradually slopes downward in the direction close to the paper taking port 121.

[0054] Specifically, when the paper printed by the first printing device reaches the storage channel 211 from the paper outlet, the part of the paper above the receiving section 212a can be attached to the surface of the receiving section 212a under the action of gravity, so that the part of the paper near the paper outlet of the printing device gradually tilts upward in the direction away from the paper outlet of the first printing device, while the part of the paper away from the paper outlet of the first printing device will be located at the sending section 212b. At this time, the paper will slide to the position of the paper pickup port 121 under the action of inertia. In this way, even when there are a large number of papers stored in the storage channel 211, they will not stack at the position of the receiving section 212a of the storage channel 211, enabling the first printing device to continuously send the printed papers through the paper outlet into the storage channel 211, and reducing the risk of paper stacking at the receiving section 212a. And one end of the receiving section near the paper outlet of the first printing device is lower than the paper outlet of the printing device. In this way, even when the papers stacked at the receiving section 212a reach a certain height, the subsequent papers can still slide well along the inclined part of the stacked papers near the paper outlet of the first printing device to the sending section 212b when being continuously sent out, reducing the risk of the subsequent papers hitting the end of the stacked papers. Compared with the way that the bottom wall 212 of the storage channel 211 is flat, this can increase the stacking height of the papers in the storage channel 211, thereby increasing the paper storage capacity of the storage structure. In addition, the paper slides to the position of the paper pickup port 121 through the sending section 212b, so that when the user picks up the item, they do not need to reach deep into the storage channel 211 to take out the printed paper from the paper pickup port 121, improving the convenience of the user to pick up the item.

[0055] In addition, by setting both the receiving section 212a and the sending section 212b as gradually downward inclined structures, the paper storage structure 21 is formed into an upwardly arched structure. Compared with the traditional paper storage structure set as a flat structure, it can also shorten the length of the paper storage structure 21, so as to reduce the overall volume of the paper storage structure 21, which is beneficial to reducing the thickness of the self-service printer in the front-rear direction, that is, reducing the occupied space of the self-service printer.

[0056] In some embodiments, the bottom wall 212 of the storage channel 211 further includes a transition section 212c connected between the receiving section 212a and the sending section 212b, and the transition section 212c is in an upwardly arched arc shape. Specifically, the arc-shaped transition section 212c can make the paper slide more smoothly to the sending section 212b. At the same time, the arc-shaped transition section 212c also prevents the paper below from being pressed out of indentations when the papers stack at the transition section 212c. Optionally, the receiving section 212a, the sending section 212b and the transition section 212c are integrally formed sheet metal parts. Of course, in other embodiments, the bottom wall 212 of the storage channel 211 may not be provided with the transition section 212c.

[0057] In some embodiments, the cabinet body 10 includes a housing 11 and a cabinet door 12. An opening 112 is provided on the front side of the housing 11. The opening 112 communicates with the interior of the housing 11. The first printing device and the second printing device are both installed inside the housing 11. The cabinet door 12 is rotatably installed at the opening 112. The cabinet door 12 is provided with a paper taking port 121. The paper storage structure 21 and the guiding structure 22 are both installed on the cabinet door 12. The guiding structure 22 is located above the paper storage structure 21.

[0058] Specifically, the housing 11 has an installation cavity 111. An opening 112 is provided on the front side of the housing 11. The opening 112 communicates with the installation cavity 111. The cabinet door 12 is rotatably installed at the opening 112 for opening and closing the opening 112. The paper taking port 121 is provided on the cabinet door 12. The paper storage structure 21 is installed on the cabinet door 12 corresponding to the paper taking port 121. The guiding structure 22 is installed on the cabinet door 12 and is located above the paper storage structure 21. In this way, when installing the paper storage structure 21 and the guiding structure 22, the staff has more activity space, which can reduce the installation difficulty of the paper storage structure 21 and the guiding structure 22. Of course, in other embodiments, the paper taking port 121 is provided on the housing 11.

[0059] Further, the self-service printer further includes a mounting plate 30 and screws. One end of the mounting plate 30 is fixed to the guiding structure 22, and the other end is provided with a through hole. The cabinet door 12 is provided with a threaded hole corresponding to the through hole. The screw is screwed into the threaded hole through the through hole. That is to say, the guiding structure 22 is installed on the cabinet door 12 through the mounting plate 30 and the screws, with a simple structure and convenient installation.

[0060] Further, the cabinet body 10 further includes a mounting rack 13. The mounting rack 13 has a first mounting position and a second mounting position arranged at intervals up and down. The first printing device is installed at the first mounting position, and the second printing device is installed at the second mounting position. The housing 11 surrounds the outside of the mounting rack 13. Specifically, the mounting rack 13 is used to provide mounting positions for the first printing device and the second printing device. That is, when installing the first printing device and the second printing device, the first printing device and the second printing device can be installed on the mounting rack 13, and the mounting rack 13 is used to support the first printing device and the second printing device. In this way, the installation of the first printing device and the second printing device can be made more stable, and at the same time, the installation difficulty of the first printing device and the second printing device can be reduced. Of course, in other embodiments, the first printing device and the second printing device are both installed on the inner side wall of the housing 11.

[0061] In some embodiments, the self-service printer further includes a baffle 50, which is disposed at the paper access port 121 and is used to open and close the paper access port 121. The baffle 50 is movably disposed at the paper access port 121 and is used to open and close the paper access port 121. This configuration prevents rainwater from entering the cabinet 10 through the paper access port 121, thereby reducing the risk of water ingress into the paper access port 121. Optionally, the baffle 50 is provided with a grip 51 for gripping, i.e., a user can grip the grip 51 to open the baffle 50. This configuration improves the user experience.

[0062] In some embodiments, the printer cabinet further includes a display screen 40, which is located on the cabinet door 12. The display screen 40 can be used to display advertisements or prompts, such as weather information. This configuration helps increase the commercial value of the self-service printer. Specifically, the display screen 40 can be a touch screen 40, allowing users to operate the system directly on the screen 40. Of course, the display screen 40 can also be a non-touch screen 40 equipped with operation buttons.

[0063] The above are only preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
