Description

Technical Field

[0001] This utility model relates to a light guide structure for a card reader, belonging to the field of POS machines. Background Technology

[0002] In POS machine card swiping interaction scenarios, most rely on voice prompts or on-screen text guidance. Both of these methods have limitations in noisy environments. Voice prompts depend on auditory reception, and their effectiveness is easily affected by the environment and the user's own conditions. For example, in noisy scenarios such as supermarkets, farmers' markets, and shopping districts, the POS machine's prompts may be covered by ambient noise, and users may not be able to hear the key instructions at all, leading to operation delays or repeated operations. Users with hearing impairments or the elderly, or other users with weak hearing, may not be able to receive sound information at all, directly causing interaction barriers and violating the principles of accessibility design.

[0003] On-screen text relies on visual reading, and its drawbacks are mainly "not being able to see clearly" and "not being able to understand". Most POS machine screens are small in size, and small fonts are often used to accommodate more information. Elderly users or those with deteriorating vision need to get close to the screen to see it clearly, which is inconvenient to operate. Secondly, for people with limited literacy, such as children and some elderly users, complex instructions may be difficult to understand, such as "Please select transaction type: consumption / pre-authorization".

[0004] Therefore, this utility model provides a card reader wall light guide structure with an indicator light design to quickly convey the operation status and reduce the user's understanding cost. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a light guide structure for card swiping walls.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0037] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0038] Example 1 Reference Figures 1 to 5 As shown, this embodiment provides a specific implementation of a card reader light guide structure, including a first housing 10, a circuit board 20, a first magnetic head sensor 30, a first card reader 40, and a battery cover 50. The circuit board 20 is disposed inside the first housing 10. The first magnetic head sensor 30 is provided on the side of the first housing 10, and the first magnetic head sensor 30 is also electrically connected to the circuit board 20 located inside the first housing. The battery cover 50 is detachably and fixedly connected to the back of the first housing 10. The first housing 10 has a second stud 103 inside, and a slot 101 and a limiting block 102 are provided on the back of the first housing 10.

[0039] The above description summarizes the structure common to both single and dual magnetic head POS machines, as well as the disassembly structure required for connecting and disconnecting different types of card readers, such as the second stud 103, card slot 101, and limit block 102. The first magnetic head sensor 30 is fixed on the first housing 10 and electrically connected to the circuit board 20, which can be used to swipe an independent magnetic track. Only the first card reader 40 needs to be installed to assemble a single magnetic head POS machine.

[0040] Specifically as follows: The first card reader wall 40 is detachably and fixedly connected to the side of the first housing 10 to shield the first magnetic head sensor 30.

[0041] In this embodiment, the first card reader wall 40 includes a horizontal portion 401 and a vertical portion 402 that are perpendicular to each other. The outer contour of the vertical portion 402 corresponds to the side of the first housing 10. When the horizontal portion 401 of the first card reader wall 40 is inserted into the back of the first housing 10, the vertical portion 402 fits with the side of the first housing 10 and shields the first magnetic head sensor 30.

[0042] Furthermore, the horizontal portion 401 is provided with a pin 411 and a protrusion 412 at the horizontal level. The back of the first housing 10 corresponding to the pin 411 is provided with a slot 101 and a limiting block 102. By disassembling and assembling the pin 411 and the slot 101, as well as the protrusion 412 and the limiting block 102, the first card-swiping wall 40 can be detachably and fixedly connected to the back of the first housing 10.

[0043] Furthermore, the horizontal part 401 is also provided with a number of studs 414, which penetrate through the end faces of both ends of the horizontal part 401. The first housing 10 corresponding to the studs 414 is provided with a second stud 103 inside. When the first card reader wall 40 is inserted into the back of the first housing 10, the studs 414 and the second studs 103 are also aligned and fixedly connected by screws or bolts.

[0044] In practical applications, to remove the first card reader wall 40, first remove the battery cover 50. The removal of the battery cover 50 can be referred to the patent application number CN202221993434.2, entitled "A Battery Cover Sliding Structure for a POS Machine". Unscrew the screws on the connecting stud 414 and the second stud 103, and then remove the first card reader wall 40 from the card slot of the first housing 10. At this time, the first magnetic head sensor 30 will be exposed on the side of the first housing 10.

[0045] Conversely, when installing the first card reader wall 40, while assembling the first card reader wall 40 with the card slot of the first housing 10, the first card reader wall 40 is detachably and fixedly connected to the back of the first housing 10 by firstly using the disassembly and assembly of the pin 411, the card slot 101, the protrusion 412, and the limiting block 102. At the same time, the stud 414 and the second stud 103 are also aligned and fixedly connected by screws or bolts. Finally, the battery cover 50 is reinstalled.

[0046] Example 2 Reference Figures 5 to 14As shown, this embodiment differs from Embodiment 1 in that the type of card reader wall installed on the side of the first housing is different. In this embodiment, a second card reader wall 60 is installed. Specifically, the first card reader wall 40 is replaced by the second card reader wall 60. The second card reader wall 60 is detachably and fixedly connected to the side of the first housing 10. A second magnetic head sensor 603 is installed on the second card reader wall 60. Together with the first magnetic head sensor 30 originally installed on the side of the first housing 10, a dual magnetic head POS machine is formed, which reads information from two independent magnetic strips.

[0047] In this embodiment, the second card reader wall 60 includes a second housing 601 and a third housing 602, which are detachably and fixedly connected.

[0048] Furthermore, the second housing 601 includes a second horizontal portion 611; a second pin 612 and a second protrusion 613 disposed at both ends of the second horizontal portion 611; the first card reader wall 40 is detachably and fixedly connected to the back of the first housing 10 by the disassembly and assembly of the second pin 612 and the card slot 101 and the second protrusion 613 and the limiting block 102.

[0049] Furthermore, it also includes a third stud 614 disposed on the second horizontal portion 611; when the second card reader wall 60 is inserted into the back of the first housing 10, the stud 414 and the second stud 103 are also aligned and fixedly connected by screws or bolts; so that the first card reader wall 40 can be detachably and fixedly connected to the back of the first housing 10.

[0050] Similar to the disassembly and assembly method in Embodiment 1, in practical applications, to remove the second card reader 60, first remove the battery cover 50, unscrew the screws connecting the third stud 614 and the second stud 103, and then remove the second card reader 60 from the card slot of the first housing 10. At this time, the first magnetic head sensor 30 will be exposed on the side of the first housing 10.

[0051] Conversely, when installing the second card reader 60, while assembling the second card reader 60 with the card slot of the first housing 10, the second pin 612 and the card slot 101, as well as the second protrusion 613 and the limiting block 102 are disassembled and assembled to make the second card reader 60 detachably and fixedly connected to the back of the first housing 10. At the same time, the third stud 614 and the second stud 103 are also aligned and fixedly connected with screws or bolts. Finally, the battery cover 50 is reinstalled.

[0052] In this embodiment, the second card reader wall 60 further includes a second magnetic head sensor 603 and a magnetic head bracket (604). The magnetic head bracket (604) is installed in the space between the vertical portion of the second housing 601 and the third housing 602. The second magnetic head sensor 603 is installed on the magnetic head bracket (604). The second magnetic head sensor 603 is exposed on the inner wall of the second housing 601, and the second magnetic head sensor 603 is electrically connected to the circuit board 20 located inside the first housing.

[0053] In this embodiment, there are two studs 414 to maintain a balanced effect when locked.

[0054] In this embodiment, both the second magnetic head sensor 603 and the first magnetic head sensor 30 include a magnetic core 631, a winding 632, a second circuit board 633, and pins 634. The magnetic core 631 is disposed on the second circuit board 633, and the winding 632 is uniformly wrapped around the second circuit board 633. The second circuit board 633 is electrically connected to the circuit board 20 through the pins 634.

[0055] The structural design of the second card reader 60 ensures the structural stability of the component during use, reduces card swiping failures caused by loose parts, and improves the reliability and service life of the equipment.

[0056] The second card reader wall 60 also includes a light guide post 607, an indicator light 608, and an LED light 609 disposed between the second housing 601 and the third housing 602. The indicator light 608 is embedded in the top surface of the third housing 602. The light guide post 607 is located between the second housing 601 and the third housing 602, and the light guide post 607 and the indicator light 608 are engaged at their horizontal ends.

[0057] The LED 609 is located on the second circuit board 633, and the LED 609 and the light guide post 607 are on the same horizontal line. The LED 609 emits light on the second circuit board 703, and the light is guided by the light guide post 607 so that the indicator light 608 can emit light evenly.

[0058] In this embodiment, the light guide column 607 and the indicator light 608 are both made of plastic material, which is inexpensive and has high light transmission efficiency.

[0059] In this embodiment, the specific structure and principle of the detachable connection between the light guide post 607 and the indicator light 608 are as follows: The light guide column 607 is a polygonal prism, including but not limited to a triangular prism, which better guides the light and reduces the energy loss of the light during transmission, and provides sufficient brightness when the light is transmitted to the indicator light 608.

[0060] The indicator light 608 includes a base plate 681 and a plurality of third protrusions 682 disposed on the base plate 681. The third protrusions 682 extend through to the outer surface of the third housing 602 and are exposed to the outside. When the indicator light 608 flashes, the operator can see it immediately, providing an intuitive and timely visual guidance method.

[0061] The third protrusion 682 is hollow inside. Compared with a solid structure, this reduces the light propagation distance and the inherent optical properties of the material, thereby reducing the energy loss of light transmission and making the indicator light brighter.

[0062] Limiting posts 610 are vertically fixed at both horizontal ends of the light guide post 607. The indicator lights 608 corresponding to the limiting posts 610 have slots 683 at both horizontal ends. The limiting posts 610 and the slots 683 are inserted into each other. In addition, the second housing 601 and the third housing 602 constrain the indicator lights 608 to achieve a detachable and fixed connection between the light guide post 607 and the indicator lights 608.

[0063] The above description details the necessary technical features for solving the problem. A side-emitting LED 609 is integrated into the second circuit board 633 of the second magnetic head sensor 603. Through the light guide column 607 and the indicator light 608, the light is precisely controlled and transmitted, and the light is emitted evenly at the position of the indicator light. This intuitive and immediate visual guidance method clearly indicates the card swiping area.

[0064] Combining the two embodiments, this utility model uses a first card reader wall or a second card reader wall 60 installed on the side of the first housing 10 to form a single-head POS machine or a dual-head POS machine. It adopts a pin and screw fixing method and an independent modular architecture. By using a hidden pin and screw fixing method in the first card reader wall or the second card reader wall 60, it can achieve seamless switching between single-head and dual-head configurations, significantly improving the equipment reuse rate and maintenance flexibility.

[0065] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
