[0036] The present utility model provides a self-service printer.

[0037] In the embodiments of the present utility model, as Figures 1 to 5 shown, the self-service printer includes a cabinet 10, an electric control device, a printing device, a display screen 20, and a sensor 30.

[0038] The printing device is a device for printing documents or photos, and this device can refer to the prior art and will not be elaborated here. Among them, the printing device can be a color inkjet printer or a color laser printer, etc., or it can also be an ordinary black-and-white printer, which can be specifically set according to actual needs, and the present application does not make specific limitations on this.

[0039] Specifically, the cabinet body 10 is provided with an installation cavity 1111 and a paper outlet 1121. The paper outlet 1121 is arranged on the front side of the cabinet body 10 and is communicated with the installation cavity 1111. The electric control device is installed in the cabinet body 10. The printing device is installed in the installation cavity 1111 and is electrically connected to the electric control device. The paper outlet position of the printing device is communicated with the paper outlet 1121. The display screen 20 is installed on the front side of the cabinet body 10 and is electrically connected to the electric control device. The sensor 30 is installed on the front side of the cabinet body 10 and is electrically connected to the electric control device. The sensor 30 is configured to send an electrical signal to the electric control device when detecting someone in front of the cabinet body 10. The electric control device is configured to control the display screen 20 to light up when receiving the electrical signal sent by the sensor 30.

[0040] The paper outlet 1121, the display screen 20 and the sensor 30 are all located on the front side of the cabinet body 10. Such a setting enables the user to operate the self-service printer and pick up the items only in front of the cabinet body 10 without moving to the side of the cabinet body 10. Moreover, when placing the self-service printer, there is no need to consider the problem of users picking up items. In other words, when placing the self-service printer, there is no need to space the side of the cabinet body 10 from other objects, resulting in the problem that the self-service printer occupies a large space.

[0041] Specifically in actual use, when the sensor 30 detects someone in front of the cabinet body 10, it will send an electrical signal to the electric control device. When the electric control device receives the electrical signal sent by the sensor 30, it will control the display screen 20 to light up to display the printing information. Among them, the printing information displayed on the display screen 20 can be printing operation steps, printing progress, etc. When the sensor 30 does not detect someone in front of the cabinet body 10, the electric control device will control the display screen 20 to turn off the screen to save power.

[0042] It is worth noting that the sensor 30 can selectively send electrical signals. In an embodiment, when the sensor 30 detects someone in front of the cabinet body 10, it will send a first electrical signal to the electric control device. When the electric control device receives the electrical signal sent by the sensor 30, it will control the display screen 20 to light up. When the sensor 30 does not detect someone in front of the cabinet body 10, it will send a second electrical signal to the electric control device. When the electric control device receives the second electrical signal sent by the sensor 30, it will control the display screen 20 to turn off the screen.

[0043] Among them, after the electric control device receives the second electrical signal sent by the sensor 30, it can immediately control the display screen 20 to turn off the screen, or it can control the display screen 20 to turn off the screen after a certain period of time after receiving the second electrical signal sent by the sensor 30. It can be specifically set according to actual needs, and this application does not make specific restrictions on this.

[0044] In another embodiment, when the sensor 30 detects someone in front of the cabinet body 10, it continuously sends an electrical signal to the electronic control device. When the electronic control device receives the electrical signal sent by the sensor 30, it controls the display screen 20 to light up. When the sensor 30 does not detect anyone in front of the cabinet body 10, it stops sending the electrical signal to the electronic control device. When the electronic control device does not receive the electrical signal sent by the sensor 30, it controls the display screen 20 to turn off the screen.

[0045] Among them, after the electronic control device does not receive the electrical signal sent by the sensor 30, it can immediately control the display screen 20 to turn off the screen, or control the display screen 20 to turn off the screen after a certain period of time without receiving the electrical signal sent by the sensor 30. Specifically, it can be set according to actual needs, and this application does not make specific restrictions on this.

[0046] Exemplarily, this time can be, but is not limited to, 5 seconds, 10 seconds, 15 seconds, etc., and can be specifically set according to actual needs. Optionally, the sensor 30 can be, but is not limited to, an infrared sensor, a laser sensor, a microwave radar, etc. Specifically, it can be set according to actual needs.

[0047] The cabinet body 10 of the technical solution of the present utility model is provided with an installation cavity 1111 and a paper outlet 1121. The paper outlet 1121 is arranged on the front side of the cabinet body 10. The electronic control device is installed in the cabinet body 10, the display screen 20 is arranged on the front side of the cabinet body 10, and the sensor 30 is arranged on the front side of the display screen 20. In this way, the paper outlet 1121, the display screen 20 and the sensor 30 are all arranged on the front side of the cabinet body 10, so that the user can complete the operation of the automatic printer and pick up the item in front of the cabinet body 10 without moving to the side of the cabinet body 10 to pick up the item. Moreover, by setting the sensor 30 to detect whether there is someone in front of the cabinet body 10, when someone is detected, the sensor 30 will send an electrical signal to the electronic control device, and the electronic control device will control the display screen 20 to light up when it receives the electrical signal sent by the sensor 30. When the sensor 30 does not detect anyone in front of the cabinet body 10, the electronic control device will control the display screen 20 to turn off the screen to save power. That is to say, the user of the self-service printer of this application does not need to move to the side of the cabinet body 10 to pick up the item, which is also beneficial to saving power and can effectively improve the practicability of the self-service printer.

[0048] In some embodiments, the sensor 30 is arranged at the upper position of the cabinet body 10. Specifically, installing the sensor 30 at the upper position of the cabinet body 10 can prevent small animals from triggering detection when passing in front of the cabinet body 10. Such a setting is beneficial to improving the detection accuracy of the sensor 30. Of course, in other embodiments, the sensor 30 can also be arranged at the middle position or the lower position of the cabinet body 10.

[0049] Further, the display screen 20 is disposed at the upper position of the cabinet 10, and the sensor 30 is located below the display screen 20. That is, both the display screen 20 and the sensor 30 are disposed at the upper position of the cabinet 10, and the sensor 30 is located below the display screen 20. Such a setting can prevent the installation position of the sensor 30 from being too high. When the installation height of the sensor 30 is higher than the height of the user, detection cannot be achieved. In this embodiment, when the sensor 30 is disposed below the display screen 20, the height of the user can enter the detection range of the sensor 30 to achieve accurate detection, thereby further improving the detection accuracy of the sensor 30. Of course, in other embodiments, the sensor 30 is disposed above or beside the display screen 20.

[0050] In some embodiments, the sensor 30 is an infrared sensor. It can be understood that the infrared sensor has advantages such as high detection sensitivity and fast response. When applied to the technical solution of the present application, the detection sensitivity of the sensor 30 can be improved. Among them, the model of the infrared sensor can be ITR001 infrared reflective photoelectric sensor, GP2AP002S00F infrared proximity sensor, LTH-1550-01 reflective photoelectric sensor, etc. Of course, in other embodiments, the sensor 30 can also be a laser sensor, a microwave radar, etc. When the sensor 30 is a microwave radar, the periphery of the cabinet 10 can be detected.

[0051] In some embodiments, the cabinet 10 includes a housing 11 and a mounting frame 12. The housing 11 is provided with a mounting cavity 1111 and a paper outlet 1121. The housing 11 surrounds the outside of the mounting frame 12, and the printing device is installed on the mounting frame 12. That is, when installing the printing device, the printing device can be installed on the mounting frame 12, and the mounting frame 12 is used to support the printing device. This can make the installation of the printing device more stable and at the same time reduce the installation difficulty of the printing device. Of course, in other embodiments, the printing device is installed on the inner side wall of the housing 11.

[0052] In some embodiments, the mounting frame 12 includes at least two support members 121 and a carrier seat 122. The two support members 121 are respectively disposed on opposite side walls of the mounting cavity 1111 and extend in the vertical direction (refer to Figure 2 the direction indicated by the arrow X), and the carrier seat 122 is adjustably installed between the two support members 121 in the vertical direction through a locking mechanism.

[0053] Specifically, the fixing member is strip-shaped, and the position of the carrier seat 122 in the vertical direction is adjustable, so that the size of the space where the printing device is located in the installation cavity 1111 can be adjusted. In other words, the size of the installation cavity 1111 can be adjusted according to the size of the printing device, so that the printing device can be better installed in the installation cavity 1111, improving the adaptability to printing devices of different sizes. In addition, when there is a gap between the carrier seat 122 and the bottom plate of the cabinet body 10, the space between the carrier seat 122 and the bottom plate of the cabinet body 10 can be used for storing items, improving the space utilization rate of the installation cavity 1111. Among them, the locking mechanism can be a threaded fastener, a clamp, etc. Of course, in other embodiments, the carrier seat 122 is fixedly installed between the two support members 121.

[0054] Furthermore, the mounting rack 12 includes a plurality of carrier seats 122. The plurality of carrier seats 122 are all installed between the two support members 121, and the plurality of carrier seats 122 are arranged at intervals in the vertical direction. There are at least two carrier seats 122, that is, there is a gap between two adjacent carrier seats 122. With such a setting, after the printing device is installed on one of the carrier seats 122, installation positions can still be provided for other modules, so that other modules can be stably installed in the installation cavity 1111. Exemplarily, the plurality of carrier seats 122 can be, but are not limited to, two, three, four, etc.

[0055] In some embodiments, the housing 11 includes a housing body 111 and a cabinet door 112. The housing body 111 is provided with an installation cavity 1111. An opening 1112 is provided on the front side of the housing body 111, and the cabinet door 112 is arranged at the opening 1112. The paper outlet 1121, the display screen 20 and the sensor 30 are all arranged on the cabinet door 112;

[0056] The carrier seat 122 includes a carrier plate 1221 and two mounting seats 1222. The two mounting seats 1222 are respectively arranged on the two support members 121 and extend in a first direction. The first direction is perpendicular to the extending direction of the support member 121. The carrier plate 1221 is slidably installed between the two mounting seats 1222 and can extend out from the opening 1112.

[0057] Specifically, when installing the printing device, the carrier plate 1221 can be slid out from the opening 1112 of the cabinet body 10. In this way, when installing the printing device, it provides sufficient space for the staff to move, thereby reducing the installation difficulty of the printing device. After the printing device is installed, the carrier plate 1221 can be pushed back into the installation cavity 1111. Optionally, a limiting structure is provided on the carrier plate 1221, and a limiting portion is provided on the mounting seat 1222. The limiting structure and the limiting portion are in limiting cooperation to limit the carrier plate 1221 in the installation cavity 1111. Of course, in other embodiments, the carrier plate 1221 is fixedly installed between the two mounting seats 1222.

[0058] In some embodiments, the self-service printer further includes a storage structure 40. The storage structure 40 is connected to the paper outlet 1121 and the paper output position of the printing device, and is used to receive documents or photos coming out from the paper output position of the printing device. Specifically, the printed documents or photos can fall from the paper output position of the printing device to the storage structure 40 and be stored through the storage structure 40. The user does not need to receive the printed documents or photos at the paper outlet 1121. After printing is completed, the user only needs to take out the printed documents or photos from the storage structure 40. Such a setting is beneficial to improving the user experience. Of course, in other embodiments, the self-service printer may not be provided with the storage structure 40.

[0059] Further, the storage structure 40 has an inclined section, and the inclined section gradually slopes downward in the direction pointing from the paper output position of the printing device to the paper outlet 1121. That is, when the printed documents or photos fall from the paper output position of the printing device to the storage structure 40, the inclined section can play a guiding role for the printed documents or photos, so that the documents or photos slide to the position of the paper outlet 1121. In this way, when the user picks up the items, there is no need to put the hand into the interior of the storage structure 40, and it is also convenient for the user to check whether there are any documents or photos left, thereby improving the user experience. Of course, in other embodiments, the storage structure 40 may not be provided with an inclined section.

[0060] In some embodiments, the self-service printer further includes a baffle 50. The baffle 50 is provided at the paper outlet 1121 and is used to open and close the paper outlet 1121. The baffle 50 is movably provided at the paper outlet 1121 and is used to open and close the paper outlet 1121. Such a setting can prevent foreign objects, dust and water from entering the cabinet 10 through the baffle 50, thereby improving the dust and water resistance of the self-service printer. Of course, in other embodiments, the baffle 50 may not be provided at the paper outlet 1121.

[0061] Further, the baffle 50 is provided with a gripping portion 51, and the gripping portion 51 is used for the user to hold. That is, the user can open the baffle 50 by gripping the gripping portion 51. Such a setting is beneficial to improving the user experience.

[0062] Further, the self-service printer further includes an electronic lock. The electronic lock is provided on the cabinet body 10. The baffle 50 is provided with a lock hole, and the lock tongue of the electronic lock is inserted into the lock hole to fix the baffle 50 in the closed state. The electronic lock is electrically connected to the electronic control device, and the electronic control device is used to control the opening and closing of the electronic lock. That is, before the user needs to open the baffle 50, the electronic lock needs to be unlocked first before the baffle 50 can be opened. In this way, when the user leaves the range of the self-service printer during the waiting for printing, it can prevent others from opening the baffle 50 to take documents or photos. Among them, the unlocking 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 20 to unlock. In another embodiment, the electronic lock is automatically unlocked after the user's document or photo is printed. Of course, in other embodiments, the self-service printer may not be provided with an electronic lock.

[0063] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention.
