Description

Technical Field

[0001] The utility model relates to the technical field of printers, and particularly relates to a self-service printer. Background Art

[0002] A self-service printer is a self-service printing device that is increasingly widely used. It can obtain the information to be printed through methods such as card reading, scanning, and manual input, and print out the information to be printed, making printing more convenient.

[0003] During the use of a self-service printer, when the printing device inside the self-service printer receives the file to be printed sent by the user, the printing device sends the printed paper into the storage mechanism for the user to pick up from the paper outlet. Currently, the storage mechanism usually adopts a flat structure. When multiple sheets of paper are sent into the storage mechanism, the multiple sheets of paper will be stacked in the storage mechanism. However, when the paper in the storage mechanism is stacked to a certain height, the end of the stacked paper will block the newly printed paper from entering the storage mechanism, resulting in a reduction in the amount of paper that can be stored in the storage mechanism. Summary of the Utility Model

[0004] The main purpose of the utility model is to propose a self-service printer, aiming to improve the paper storage capacity of the storage structure.

[0005] To achieve the above object, the self-service printer proposed by the utility model includes:

[0006] A cabinet body, with a paper outlet provided on one side of the cabinet body, and the paper outlet is communicated with the inside of the cabinet body;

[0007] A printing device, arranged inside the cabinet body; and

[0008] A storage structure, having a storage channel, the bottom wall of the storage channel has a receiving section and a sending section connected to each other. The receiving section is arranged close to the paper outlet of the printing device. The receiving section gradually slopes downward in the direction close to the paper outlet of the printing device, and one end of the receiving section close to the paper outlet of the printing device is lower than the paper outlet of the printing device. The sending section is arranged close to the paper outlet, and gradually slopes downward in the direction close to the paper outlet.

[0009] Optionally, the bottom wall of the storage channel further includes a transition section connected between the receiving section and the sending section, and the transition section is in an upwardly arched shape.

[0010] Optionally, the receiving section, the sending section, and the transition section are integrally formed sheet metal parts.

[0011] Optionally, a buffer portion is provided between the paper pickup port and the delivery end of the storage channel. The buffer portion has a buffer plane extending in a direction away from the storage channel, and the bottom wall of the delivery end of the storage channel is lapped on the buffer plane.

[0012] Optionally, a retaining edge extending upward is provided on the bottom wall of one end of the buffer portion away from the delivery end of the storage channel.

[0013] Optionally, an installation hole is provided on the top surface of the storage channel. The self-service printer further includes a lighting member installed in the installation hole, and the light-emitting side of the lighting member faces the storage channel.

[0014] Optionally, a plurality of heat dissipation holes are provided on the bottom wall of the storage channel. The heat dissipation holes are in the shape of long strips extending along the length direction of the storage channel, and the plurality of heat dissipation holes are spaced apart in the width direction of the storage channel.

[0015] Optionally, the self-service printer further includes a paper output platform provided at the paper output port of the printing device. The paper output platform has a guiding portion disposed close to the paper output structure, and the guiding portion is gradually inclined upward in a direction close to the storage structure.

[0016] Optionally, the cabinet body includes a housing and a cabinet door. An opening is provided on the front side of the housing and is in communication with the interior of the housing.

[0017] Optionally, the self-service printer further includes a baffle disposed at the paper pickup port for opening and closing the paper pickup port.

[0018] The technical solution of the present utility model sets the bottom wall of the storage channel as a receiving section and a sending section that are connected to each other. The receiving section is arranged close to the paper outlet of the printing device and gradually slopes downward in the direction close to the paper outlet of the printer device. In this way, when the paper printed by the printing device reaches the storage channel from the paper outlet, the part of the paper above the receiving section can be attached to the surface of the receiving section under the action of gravity, so that the part of the paper close to the paper outlet of the printing device gradually slopes upward in the direction away from the paper outlet of the printing device, while the part of the paper away from the paper outlet of the printing device is located in the sending section. At this time, the paper will slide to the position of the paper pickup port under the action of inertia. In this way, even when there are many papers stored in the storage channel, they will not stack at the position of the receiving section of the storage channel, enabling the printing device to continuously send the printed paper to the storage channel through the paper outlet, which can reduce the risk of paper stacking at the receiving section. And one end of the receiving section close to the paper outlet of the printing device is lower than the paper outlet of the printing device. In this way, even when the papers in the receiving section are stacked to a certain height, the subsequent papers can still slide well along the inclined part of the stacked papers close to the paper outlet of the printing device to the sending section when being continuously sent out, which can reduce the risk of the subsequent papers hitting the end of the stacked papers. Compared with the way that the bottom wall of the storage channel is flat, this can increase the stacking height of the papers in the storage channel, thereby improving the paper storage capacity of the storage structure. In addition, the paper slides to the position of the paper pickup port through the sending section, so that when the user picks up the paper, they do not need to reach deep into the storage channel to take out the printed paper from the paper pickup port, improving the convenience of the user to pick up the paper.

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0032] The present utility model proposes a self-service printer.

[0033] In an embodiment of the present utility model, as Figures 1 to 6 shown, the self-service printer includes a cabinet body 10, a printing device, and a storage structure 20.

[0034] Specifically, the cabinet body 10 is provided with an installation cavity. One side of the cabinet body 10 is provided with a paper taking port 121, and the paper taking port 121 communicates the installation cavity with the external environment. The printing device is installed in the installation cavity. As we know, the printing device is a device for printing documents or photos, and this device can refer to the prior art, and this application will not elaborate on it one by one. Among them, the printing device can be a color inkjet printing device or a color laser printing device, etc. Of course, it can also be an ordinary black-and-white printing device, which can be specifically set according to actual needs, and this application has no specific restrictions on this.

[0035] The storage structure 20 has a storage channel 21. The bottom wall 211 of the storage channel 21 has a receiving section 211a and a sending section 211b that are connected to each other. The receiving section 211a is arranged close to the paper outlet of the printing device. The receiving section 211a gradually slopes downward in the direction close to the paper outlet of the printing device, and one end of the receiving section 211a close to the paper outlet of the printing device is lower than the paper outlet of the printing device. The sending section 211b is arranged close to the paper taking port 121 and gradually slopes downward in the direction away from the receiving section 211a.

[0036] When the paper printed by the printing device reaches the storage channel 21 from the paper outlet, the part of the paper above the receiving section 211a can be attached to the surface of the receiving section 211a under the action of gravity, so that the part of the paper close to the paper outlet of the printing device gradually slopes upward in the direction away from the paper outlet of the printing device, and the part of the paper away from the paper outlet of the printing device will be located on the sending section 211b. At this time, the paper will slide to the position of the paper taking port 121 under the action of inertia. In this way, even when there are more papers stored in the storage channel 21, they will not stack at the position of the receiving section 211a of the storage channel 21, enabling the printing device to continuously send the printed papers to the storage channel 21 through the paper outlet, and reducing the risk of paper stacking at the receiving section 211a.

[0037] Furthermore, the end close to the paper outlet of the printing device is lower than the paper outlet of the printing device. In this way, even after the papers in the receiving section 211a are stacked to a certain height, when the subsequent papers are continuously fed out, they can better slide along the inclined part of the stacked papers close to the paper outlet of the printing device towards the feeding section 211b, which can reduce the risk of the subsequent papers hitting the end of the stacked papers. Compared with the way that the bottom wall 211 of the storage channel 21 is flat, this can increase the stacking height of the papers in the storage channel 21, and thus improve the paper storage capacity of the storage structure 20. In addition, the papers slide to the position of the paper pickup opening 121 through the feeding section 211b, so that when the user picks up the papers, they can take out the printed papers from the paper pickup opening 121 without reaching deep into the storage channel 21, which improves the convenience of the user for picking up the papers.

[0038] In the technical solution of the present utility model, the bottom wall 211 of the storage channel 21 is set as a receiving section 211a and a feeding section 211b connected to each other. The receiving section 211a is arranged close to the paper outlet of the printing device and gradually slopes downward in the direction close to the paper outlet of the printing device. In this way, when the papers printed by the printing device are sent from the outlet to the storage channel 21, the part of the papers above the receiving section 211a can be attached to the surface of the receiving section 211a under the action of gravity, so that the part of the papers close to the paper outlet of the printing device slopes upward gradually in the direction away from the paper outlet of the printing device, and the part of the papers away from the paper outlet of the printing device is located in the feeding section 211b. At this time, the papers will slide to the position of the paper pickup opening 121 under the action of inertia. In this way, even when there are many papers stored in the storage channel 21, they will not be stacked at the position of the receiving section 211a of the storage channel 21, so that the printing device can continuously send the printed papers through the paper outlet to the storage channel 21, which can reduce the risk of paper stacking at the receiving section 211a. Furthermore, the end close to the paper outlet of the printing device is lower than the paper outlet of the printing device. In this way, even after the papers in the receiving section 211a are stacked to a certain height, when the subsequent papers are continuously fed out, they can better slide along the inclined part of the stacked papers close to the paper outlet of the printing device towards the feeding section 211b, which can reduce the risk of the subsequent papers hitting the end of the stacked papers. Compared with the way that the bottom wall 211 of the storage channel 21 is flat, this can increase the stacking height of the papers in the storage channel 21, and thus improve the paper storage capacity of the storage structure 20. In addition, the papers slide to the position of the paper pickup opening 121 through the feeding section 211b, so that when the user picks up the papers, they can take out the printed papers from the paper pickup opening 121 without reaching deep into the storage channel 21, which improves the convenience of the user for picking up the papers.

[0039] In addition, by setting both the receiving section 211a and the sending section 211b as gradually downward inclined structures, the relative lengths of the receiving section 211a and the sending section 211b can be reduced, so as to reduce the overall volume of the storage structure 20, thereby releasing the available installation space inside the self-service printer.

[0040] In some embodiments, the length of the sending section 211b is greater than or equal to the length of the receiving section 211a. That is to say, the length of the sending section 211b can be greater than the length of the receiving section 211a; or, the length of the sending section 211b can also be equal to the length of the receiving section 211a.

[0041] When the length of the sending section 211b can be greater than the length of the receiving section 211a, when the printing device sends the printed paper to the bottom wall 211 of the storage channel 21, a small part of the paper will stick to the receiving section 211a under the action of gravity, while most of the paper will stick to the sending section 211b. And because the sending section 211b is set as a structure that gradually extends downward in the direction of the paper outlet 121, when the paper is located on the sending section 211b, it will slide towards the paper outlet 121 under the action of inertia. With such a setting, the printed paper is closer to the paper outlet 121, and the user can take out the printed paper from the paper outlet 121 without reaching deep into the upper paper outlet channel 22, improving the convenience of the user to pick up the item.

[0042] In some embodiments, the bottom wall 211 of the storage channel 21 further includes a transition section 211c connected between the receiving section 211a and the sending section 211b, and the transition section 211c is in an upwardly convex arc shape. Specifically, the arc-shaped transition section 211c can make the paper slide towards the sending section 211b more smoothly. At the same time, the arc-shaped transition section 211c also prevents the paper below from being pressed out of indentations when the paper is stacked on the transition section 211c. Optionally, the receiving section 211a, the sending section 211b and the transition section 211c are integrally formed sheet metal parts. Of course, in other embodiments, the bottom wall 211 of the storage channel 21 may not be provided with the transition section 211c.

[0043] In some embodiments, a buffer portion 40 is provided between the paper pickup opening 121 and the delivery end of the storage channel 21. The buffer portion 40 has a buffer plane extending in a direction away from the storage channel 21, and the bottom wall of the delivery end of the storage channel 21 is lapped on the buffer plane. Specifically, the paper will slide to the position of the buffer plane under the action of inertia. During this sliding process, the buffer plane can play a certain buffering role for the sliding paper, and can to a certain extent avoid the situation that the paper directly slides out of the paper pickup opening 121. Specifically, the buffer portion 40 can be provided at the delivery end of the storage channel 21; or can be provided on the side of the paper pickup opening 121 facing the storage channel 21. Optionally, anti-slip patterns are provided on the buffer plane to increase the friction with the paper. Of course, in other cases, the bottom wall 211 of the paper pickup opening 121 may not be provided with the buffer portion 40.

[0044] In some embodiments, a retaining edge 41 extending upward is provided on the bottom wall of the end of the buffer portion 40 away from the delivery end of the storage channel 21. Specifically, when the paper slides to the position of the buffer portion 40 under the action of inertia, the baffle 30 can form a resistance to the sliding paper, thereby avoiding the situation that the paper directly slides out of the paper pickup opening 121. Of course, in other embodiments, the retaining edge 41 may not be provided at the end of the buffer portion 40 away from the storage channel 21.

[0045] In some embodiments, a mounting hole 26 is provided on the top surface of the storage channel 21. The self-service printer further includes an illuminating member, and the illuminating member is installed in the mounting hole 26, and the light-emitting side of the illuminating member faces the storage channel 21. Specifically, the illuminating member is used to illuminate the storage channel 21. With such a setting, it is convenient for the user to check whether there is any paper left in the storage channel 21. Of course, in other embodiments, the self-service printer may not be provided with the illuminating member.

[0046] In some embodiments, a plurality of heat dissipation holes 25 are provided on the bottom wall 211 of the storage channel 21. The heat dissipation holes 25 are in the shape of long strips extending along the length direction of the storage channel 21, and the plurality of heat dissipation holes 25 are spaced apart in the width direction of the storage channel 21.

[0047] Specifically, the number of the heat dissipation holes 25 is at least two. The printed paper itself has a certain amount of heat. Therefore, by providing a plurality of heat dissipation holes 25 on the bottom wall 211 of the storage channel 21, the heat dissipated by the paper can be discharged from the storage channel 21 through the heat dissipation holes 25 to prevent too much heat from accumulating in the storage channel 21. In other words, the heat dissipation performance of the storage channel 21 is improved. Exemplarily, the number of the heat dissipation holes 25 can be, but is not limited to: two, three, four, etc. Of course, in other embodiments, the bottom wall 211 of the storage channel 21 may not be provided with the heat dissipation holes 25.

[0048] In some embodiments, the self-service printer further includes a paper output platform, which is arranged at the paper output port of the printing device. The paper output platform has a guiding portion disposed close to the paper output structure, and the guiding portion gradually slopes upward in the direction close to the storage structure 20.

[0049] Specifically, the paper coming out from the paper output port of the printing device will first enter the paper output platform. Since the guiding portion of the paper output platform adopts a gradually upward sloping structure, the paper entering the paper output platform at this time will slide down to the inclined surface of the receiving section 211a under the action of inertia, so as to realize the transition of the paper from the printing device to the receiving section 211a. Of course, in other embodiments, the self-service printer may not be provided with a guiding portion.

[0050] In some embodiments, the cabinet 10 includes a housing 11 and a cabinet door 12. An opening 111 is provided on the front side of the housing 11, and the opening 111 communicates with the inside of the housing 11. The printing device is installed inside the housing 11. The cabinet door 12 is rotatably installed at the opening 111. The cabinet door 12 is provided with a paper taking port 121, and the storage structure 20 is installed on the cabinet door 12.

[0051] Specifically, the housing 11 has an installation cavity. An opening 111 is provided on the front side of the housing 11, and the opening 111 communicates with the installation cavity. The cabinet door 12 is rotatably installed at the opening 111 for opening and closing the opening 111. The paper taking port 121 is provided on the cabinet door 12, and the storage structure 20 is installed on the cabinet door 12 corresponding to the paper taking port 121. In this way, when installing the storage structure 20, the staff has more activity space, which can reduce the installation difficulty of the storage structure 20. Of course, in other embodiments, the paper taking port 121 is provided on the housing 11.

[0052] Furthermore, the cabinet 10 further includes a mounting rack 60. The housing 11 surrounds the outside of the mounting rack 60, and the printing device is installed on the mounting rack 60. The mounting rack 60 is used to provide an installation position for the printing device, that is, when installing the printing device, the printing device can be installed on the mounting rack 60, and the printing device is supported by the mounting rack 60, so that the installation of the printing device can be more stable, and at the same time, the installation difficulty of the printing device can be reduced. Of course, in other embodiments, the printing device is installed on the inner side wall of the housing.

[0053] In some embodiments, the printer mechanism further includes a display screen 50, and the display screen 50 is arranged on the cabinet door 12. The display screen 50 can be used to play advertisements or display prompt messages, such as playing weather information. Such a setting is beneficial to increasing the commercial value of the self-service printer. Specifically, the display screen 50 can be set as a touch display screen 50 so that users can directly operate on the display screen 50. Of course, the display screen 50 can also be set as a non-touch display screen 50 provided with operation buttons.

[0054] Further, the display screen 50 is located above the paper pickup opening 121. This facilitates taking the paper and makes it easy to check whether there is any paper left in the storage channel 21.

[0055] In some embodiments, the self-service printer further includes a baffle 30 provided at the paper pickup opening 121 for opening and closing the paper pickup opening 121. The baffle 30 is movably provided at the paper pickup opening 121 for opening and closing the paper pickup opening 121. With such a setting, it is possible to prevent rainwater from entering the cabinet 10 through the paper pickup opening 121 through the baffle 30, thereby reducing the risk of water ingress at the paper pickup opening 121. Optionally, the baffle 30 is provided with a gripping portion 31 for users to grip, that is, users can open the baffle 30 by gripping the gripping portion 31. With such a setting, it is beneficial to improve the user experience.

[0056] Further, the printer cabinet further includes an electronic lock provided on the cabinet 10. The baffle 30 is provided with a keyhole, and the locking tongue of the electronic lock is inserted into the keyhole to fix the baffle 30 in the closed state. The electronic lock is electrically connected to the electric control device, and the electric control device is used to control the opening and closing of the electronic lock.

[0057] Specifically, that is, before the user needs to open the baffle 30, the electronic lock needs to be unlocked first before the baffle 30 can be opened. With such a setting, when the user leaves the range of the self-service printer during the waiting for printing, it can prevent others from opening the baffle 30 to take the printed paper. Among them, the unlocking method of the electronic lock can be selectively set. In one embodiment, the user can unlock on the mobile phone or operate on the display screen 50 to unlock. It should be noted that when unlocking through the display screen 50, the password needs to be entered first before unlocking. Of course, in other embodiments, the self-service printer may not be provided with an electronic lock.

[0058] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied to other related technical fields, is included in the patent protection scope of the present invention.
