Description

Technical Field

[0001] This utility model relates to the technical field of printers, and in particular to a paper tray adjustment mechanism for a portable printer. Background Technology

[0002] Portable printers are small and easy to carry. They can be used to print receipts and labels, or both. However, even with the same specifications, receipt and label paper have size discrepancies. For printers with single-sided alignment, these two types of paper cannot be simultaneously compatible with the printer system settings, resulting in a printing reference deviation. This leads to different starting reference points for printing. If printers are to print both receipts and labels simultaneously, one of the printing modes may not be centered. Utility Model Content

[0003] The purpose of this utility model is to provide a paper tray adjustment mechanism for a portable printer. The technical problem to be solved is to provide a paper tray adjustment mechanism that can switch between different printing modes.

[0004] To achieve the above objectives, the solution of this utility model is: a paper tray adjustment mechanism for a portable printer, compatible with a first printing mode and a second printing mode, comprising a housing and a card plate; The housing has a paper tray for holding printing paper and a mounting slot for storing the cardboard. The paper tray is provided with preset positions for installing the card plate, and the card plate can be detachably installed in one of the mounting slots and the preset positions; One end of the printing paper is the printing reference end. After the card is stored, the printing reference end abuts against the first side wall of the paper tray to put the printing paper in the first printing mode. After the card is installed in the preset position, the card protrudes into the paper tray to abut against the printing reference end, so that the printing reference end is separated from the first side wall to put the printing paper in the second printing mode. Furthermore, the mounting groove is formed on the first side wall of the paper tray.

[0005] Furthermore, after the pallet is stored in the mounting slot, one side wall of the pallet is exposed inside the paper tray, forming the first side wall together with the inner side wall of the paper tray.

[0006] Furthermore, an opening is provided on the top side of the paper tray, and a slot is formed on the top side of the mounting groove. The slot allows the card plate to be inserted longitudinally into the mounting groove and pulled upward out of the mounting groove.

[0007] Furthermore, the top edge of the paper bin forms an insertion port, and there are multiple insertion ports. These multiple insertion ports are horizontally spaced along the width direction of the paper bin. Each insertion port extends downward to form a first limiting groove. The top side of the card plate extends towards the insertion port to form a first insertion part that mates with the first limiting groove. After the first insertion part is inserted into different first limiting grooves, the card plate is installed in the mounting groove or in a preset position.

[0008] Furthermore, a second limiting groove is formed on the bottom wall of the paper tray, and a second insertion part is formed on the bottom side of the card plate. When the card plate is installed in a preset position, the second insertion part is inserted downward into the second limiting groove to restrict the lateral movement of the card plate and fix the card plate in the preset position.

[0009] Furthermore, the sidewalls of the card are formed with slots for hand gripping.

[0010] Furthermore, an adjustment plate is installed inside the paper tray. The adjustment plate is used to abut against the end of the printing paper away from the printing reference. The adjustment plate can move laterally inside the paper tray to adjust the width of the paper tray.

[0011] Furthermore, the paper bin has grooves formed on both sides along its width, and the adjusting plate has a sliding part that cooperates with the grooves. The sliding part slides laterally, so that the adjusting plate is located in different positions inside the paper bin.

[0012] Furthermore, the adjustment plate has raised anti-slip textures for the hand to push against.

[0013] The beneficial effects of this utility model after adopting the above solution are as follows: When the card plate is not installed in the paper tray, the printing reference end of the printing paper abuts against the first side wall of the paper tray. At this time, the printer can be used to print receipts in the center. The paper tray is also provided with a preset position for installing the card plate. When the card plate is installed in the preset position, the card plate abuts against the printing reference end of the printing paper, thereby separating the printing reference end of the printer from the first side wall of the paper tray and changing the printing reference point of the printing paper. At this time, the printer can be used to print label paper in the center, and it is convenient to switch between different printing modes to print different types of paper in the center. In addition, the housing is provided with a mounting groove for storing the card plate. When the card plate is not in use, it can be stored away, avoiding the card plate from being easily lost due to lack of storage when not in use, and making it convenient to use.

Detailed Implementation

[0021] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", "middle", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0023] like Figure 1-6As shown, this utility model provides a paper tray adjustment mechanism for a portable printer, compatible with both a first printing mode and a second printing mode. It includes a housing 1 and a card plate 2. The housing 1 has a paper tray 3 for holding printing paper 100 and a mounting slot 4 for storing the card plate 2. The mounting slot 4 can be located anywhere on the housing 1, without specific limitations, as long as it can store the card plate 2 to prevent it from being lost due to misplacement. The printing paper 100 can be a receipt, a label, or other types of paper. In this specific embodiment, the first printing mode is used for centered printing of receipts, and the second printing mode is used for centered printing of labels. The starting printing reference points for the two different types of paper 100 are different. To allow the printing reference points of different types of paper 100 to be adjusted according to specific circumstances... To ensure that different types of printing paper 100 can be printed centered, the paper tray 3 has a preset position for mounting the card plate 2. The preset position is the reference for centered printing in the second printing mode. The card plate 2 can be detachably installed in either the mounting slot 4 or the preset position. One end of the printing paper 100 is the printing reference end 110. After the card plate 2 is retracted, the printing reference end 110 abuts against the first side wall 31 of the paper tray 3, so that the printing paper 100 is in the first printing mode. After the card plate 2 is installed in the preset position, the card plate 2 protrudes into the paper tray 3 to abut against the printing reference end 110, so that the printing reference end 110 is spaced from the first side wall 31, so that the printing paper 100 is in the second printing mode. By switching different mounting positions of the card plate 2, the paper tray 3 can match different printing modes. In this specific embodiment, the mounting groove 4 is formed inside the paper tray 3. It can be formed on any side wall of the paper tray 3 or on the bottom wall of the paper tray 3, without specific limitations. Preferably, the mounting groove 4 is formed on the first side wall 31 of the paper tray 3. There are multiple ways to install the card plate 2. One way is that the mounting groove 4 is formed inside the first side wall 31. After the card plate 2 is retracted, it can be completely retracted into the mounting groove 4 and will not be exposed inside the paper tray 3. Another way is that the mounting groove 4 is exposed outside the first side wall 31, and after the card plate 2 is retracted, the outer contour formed by the card plate 2 and the mounting groove 4 is integrated with the contour of the paper tray 3, without affecting the application of the paper tray 3 in the first printing mode. Specifically, one side wall of the card plate 2 and part of the first side wall 31 together form the first side wall 31, or one side wall of the card plate 2 is used entirely as the first side wall 31. In order to save space and reduce processing costs, the key combination is... Figure 1 As shown, after the card plate 2 is stored, one side wall of the card plate 2 and the inner side wall of the paper tray 3 together form the first side wall 31. Therefore, the card plate 2 can be used as the first side wall 31. When the card plate 2 is moved laterally and installed in the preset position, it is equivalent to moving the first side wall 31 laterally, thereby changing the contact position of the printing reference end 110 of the printing paper 100, so that the paper tray 3 can be applied to the second printing mode.

[0024] Key points combined Figure 3 As shown, the card plate 2 includes a card plate body 24 and a connecting part 25. The card plate body 24 extends longitudinally for installation in the mounting groove 4, and the connecting part 25 extends laterally for connection with the paper tray 3. An opening 32 is provided on the top side of the paper tray 3. To facilitate the installation of the card plate 2, a slot opening 41 is formed on the top side of the mounting groove 4. The slot opening 41 allows the card plate 2 to be inserted longitudinally into the mounting groove 4 and to be pulled upward out of the mounting groove 4. In use, the card plate body 24 is inserted into the mounting groove 4 through the opening 32 using the space provided by the opening 32. The connecting part 25 is connected and fixed to the top edge of the paper tray 3. When disassembling, the card plate 2 is pulled upward to disengage the card plate body 24 from the mounting groove 4. Of course, in other embodiments, the card plate 2 can also be installed laterally and locked in place with the mounting groove 4.

[0025] Key points combined Figure 3-5 As shown, the top edge of the paper tray 3 forms an insertion port 5. There are multiple insertion ports 5, which are laterally spaced along the width direction of the paper tray 3. Each insertion port 5 extends downward to form a first limiting groove 6. The top side of the card plate 2 extends towards the insertion port 5 to form a first insertion part 21 that cooperates with the first limiting groove 6. Specifically, the first insertion part 21 is formed on the connecting part 25. After the first insertion part 21 is inserted into different first limiting grooves 6, the card plate 2 is installed in the mounting groove 4 or in a preset position.

[0026] To ensure that the card plate 2 is more securely installed in the preset position, the key combination is... Figure 1 As shown, a second limiting groove 33 is formed on the bottom wall of the paper tray 3, and a second insertion part 22 extends downward from the bottom side of the card plate 2. When the card plate 2 is installed in a preset position, the second insertion part 22 inserts downward into the second limiting groove 33 to restrict the lateral movement of the card plate 2 and fix the card plate 2 in the preset position. There are two second limiting grooves 33, and correspondingly, there are also two second insertion parts 22. After the two second insertion parts 22 are inserted into the two second slots 33 respectively, the installation is more stable. Specifically, the second insertion part 22 is formed on the bottom side of the card plate body 24. In addition, a third limiting groove 42 is formed on the bottom wall of the mounting groove 4 for the second insertion part 22 to be stored. In use, as shown... Figure 4 As shown, when the paper tray 3 applies the first printing mode, the card plate 2 is installed in the mounting slot 4, the second insert 22 is inserted into the third limiting slot 42, and the first insert 21 is inserted into the corresponding first limiting slot 6; as Figure 5 As shown, when the paper tray 3 applies the second printing mode, the card plate 2 is installed in the preset position, the second insert 22 is inserted into the second limiting groove 33, and the first insert 21 is inserted into the corresponding other first limiting groove 6.

[0027] To facilitate the removal of the card plate 2, a groove 23 is formed on the side wall of the card plate 2. Specifically, the groove 23 is formed on the side wall of the card plate body 24 and extends horizontally to facilitate hand removal.

[0028] Key points combined Figure 6 As shown, an adjusting plate 7 is provided inside the paper tray 3. The paper tray 3 extends laterally, and its two opposite sidewalls are the first sidewall 31 and the second sidewall 35, respectively. The adjusting plate 7 is located on one side of the second sidewall 35 and is used to abut against the end of the printing paper 100 away from the printing reference. The adjusting plate 7 can move laterally inside the paper tray 3 to adjust the width of the paper tray 3. The paper tray 3 has grooves 34 formed on both sides along the width direction. The adjusting plate 7 has sliding parts 71 formed on opposite sides. The sliding parts 71 slide in the grooves 34. When the sliding parts 71 slide laterally to different positions, they abut against the ends of printing papers 100 of different sizes. In addition, the adjusting plate 7 has protrusions forming anti-slip parts 72. The anti-slip parts 72 are used for pushing by hand. The anti-slip parts 72 are composed of several spaced protrusions. There is relative friction between the grooves 34 and the sliding parts 71. In use, the adjusting plate 7 is moved by pushing the anti-slip parts 72 by hand. After the external force is removed, the adjusting plate 7 is fixed inside the paper tray 3.

[0029] Preferably, the paper tray 3 is provided with scale markings along the width direction. The adjustment plate 7 can be precisely adjusted through the scale markings to accommodate different sizes of printing paper. When changing to different sizes of printing paper 100, the adjustment plate 7 is first moved horizontally to the corresponding scale marking, and then the printing paper 100 is placed into the paper tray 3, which is convenient for users to identify and use.

[0030] The above description is only a preferred embodiment of this utility model and is not intended to limit the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
