Description

Technical Field

[0002] Image forming devices such as printers are generally equipped with a Near Field Communication (NFC) function. For example, an NFC substrate may be configured on a printer, and when an external communication device such as a mobile phone is close to the NFC substrate, a wireless connection may be established between the external communication device and the NFC substrate, so that information such as print data in the communication device may be transmitted to the image forming device.

The cover is usually provided with a buckle, which can be snapped to a certain position on the edge of the NFC substrate; or the NFC substrate is provided with a hole, and the buckle can pass through the hole and snap to the edge of the hole. However, the above-mentioned NFC substrate fixing methods can only support a certain point of the NFC substrate through the buckle, and the supporting area is small. When the NFC substrate is affected by changes in temperature, vibration, humidity and other factors, the NFC substrate is prone to warping and deformation at the position not constrained by the buckle, which will cause the distance between the NFC substrate and the cover to change, thereby affecting the effect of near field communication.

[0087] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present application and, together with the description, serve to explain the principles of the present application. DETAILED DESCRIPTION

[0088] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0089] In the description of this application, unless otherwise clearly specified and limited, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance; unless otherwise specified or explained, the term "plurality" refers to two or more; the terms "connected" and "fixed" should be understood in a broad sense, for example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0090] In the description of this specification, it should be understood that the directional words such as "upper" and "lower" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limiting the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0091] Image forming devices such as printers are generally equipped with a Near Field Communication (NFC) function. For example, an NFC substrate may be configured on a printer, and when an external communication device such as a mobile phone is close to the NFC substrate, a wireless connection may be established between the external communication device and the NFC substrate, so that information such as print data in the communication device may be transmitted to the image forming device.

[0092] The existing NFC substrate needs to be installed on the cover of the image forming device, and the cover is usually provided with a buckle, which can be snapped into a certain position on the edge of the NFC substrate. Alternatively, the NFC substrate is provided with a hole, and the buckle can pass through the hole and snap into the edge of the hole. However, the above-mentioned fixing methods of the NFC substrate can only fix a certain point of the NFC substrate by the buckle, and the supporting area is small. When the NFC substrate is affected by changes in factors such as temperature and vibration, the position on the NFC substrate that is not constrained by the buckle is prone to warping and deformation, which will cause the distance between the NFC substrate and the cover to change, thereby affecting the effect of near field communication.

[0093] The embodiment of the present application provides an image forming device, and the imaging method of the image forming device can be electronic photography imaging, inkjet imaging, thermal head imaging, etc. The image forming device can be paired with an external communication device through near field communication as an NFC function or establish interconnection with a communication device through a wireless LAN to receive print data from the communication device through near field communication (NFC). In addition, an ID card or the like held by a user as an external communication device can be authenticated through near field communication.

[0094] Figure 1 This is a schematic diagram of the structure of the image forming device provided in the embodiment of the present application, referring to Figure 1 The image forming device may include a housing 10 and a cover plate 20. The housing 10 has a receiving space for arranging structural parts or devices. It should be noted that: Figure 1 The X direction in the figure is the left-right direction when the image forming device is viewed from the front, the Y direction is the front-back direction, and the Z direction is the up-down direction. The X direction, the Y direction, and the Z direction are perpendicular to each other. Figure 2 for Figure 1 The structural diagram of the middle cover plate 20 is shown in FIG. Figure 2 The cover 20 can be covered on the shell 10 to seal the accommodating space in the shell 10 and provide protection for the numerous structural parts or devices in the shell 10. The cover 20 can be integrated with devices such as an operation panel and a near field communication substrate 2 serving as an NFC substrate.

[0095] In this embodiment, Figure 3 for Figure 1 The local cross-sectional view at AA, Figure 4 for Figure 1 The partial cross-sectional view at BB, refer to Figure 3 and Figure 4 , the cover plate 20 may be provided with a housing 1, a near field communication substrate 2 and a support member 3. The area of ​​the housing 1 is smaller than that of the cover plate 20. The housing 1 may be a part of the structure on the cover plate 20, or the housing 1 may be a separately manufactured part that can be independently installed on the cover plate 20 of the housing 10. The housing 1 is used to cover the near field communication substrate 2, the support member 3 and other components. At the same time, a pairing area may be provided on the housing 1 so that when an external communication device approaches the pairing area, the communication device can establish near field communication with the near field communication substrate 2 in the housing 1.

[0096] Figure 5 A schematic diagram of a partial structure of an image forming device provided by an embodiment of the present application is shown in FIG. Figure 6 for Figure 5 Exploded diagram of Figure 7 for Figure 4 Bottom view of Figures 5 to 7 , an antenna 4 may be provided on the near field communication substrate 2, and the antenna 4 may realize the transmission and reception of wireless signals, so as to realize the establishment of near field communication between the near field communication substrate 2 and the external communication device. The near field communication substrate 2 may be mounted on the housing 1, and the near field communication substrate 2 may extend along a first direction X, and the first direction X is perpendicular to the thickness direction Z of the near field communication substrate 2. Among them, along the first direction X, the near field communication substrate 2 may include a first edge 21 and a second edge 22 arranged opposite to each other.

[0097] Reference Figure 5 , a mounting structure 11 may be provided on the housing 1, and the support member 3 may be connected to the mounting structure 11. The support member 3 abuts against a surface of the near field communication substrate 2 that is away from the housing 1, and at least part of the support member 3 extends from the first edge 21 to the second edge 22. Among them, the support member 3 has a large length dimension in the first direction X, and can extend continuously between the first edge 21 and the second edge 22 of the near field communication substrate 2, so that the force at each position where the near field communication substrate 2 contacts the support member 3 in the first direction X can be uniform, and the support area is large, so that the first edge 21 and the second edge 22 of the near field communication substrate 2 can be reliably supported, thereby ensuring the stable support of the near field communication substrate 2 as a whole, and at the same time, it can prevent the near field communication substrate 2 from warping and other deformations when it is affected by changes in environmental temperature, vibration and other factors, thereby ensuring the consistency of the distance between each position of the near field communication substrate 2 and the housing 1, and ensuring the matching accuracy of the near field communication substrate 2 and the housing 1.

[0098] In one embodiment, the antenna 4 is disposed on a side of the near field communication substrate 2 that is away from the support member 3, and along the thickness direction Z of the near field communication substrate 2, the projection of the antenna 4 and the projection of the support member 3 at least partially overlap. In other words, the support member 3 can be supported at the position where the antenna 4 is arranged on the near field communication substrate 2, so that the consistency of the distance between the position where the antenna 4 is arranged on the near field communication substrate 2 and the housing 1 can be ensured, which is conducive to improving the communication accuracy.

[0099] In one embodiment, referring to Figures 5 to 7 The support member 3 includes a first support section 31, which can extend in a straight line. The first support section 31 can include a first end 311 and a second end 312 that are arranged opposite to each other. The first end 311 is a portion of the first support section 31 with a certain length, and specifically, it can be a portion of the first support section 31 extending from one end surface of the first support section 31 along its length direction to a certain length in the direction of the second end 312. Similarly, the second end 312 is also a portion of the first support section 31 with a certain length, and specifically, it can be a portion of the first support section 31 extending from another end surface of the first support section 31 along its length direction to a certain length in the direction of the first end 311.

[0100] Among them, refer to Figure 7, the first end 311 protrudes from the first edge 21 of the near field communication substrate 2, the second end 312 protrudes from the second edge 22 of the near field communication substrate 2, and the first support section 31 is connected to the mounting structure 11 through the first end 311 and the second end 312. The mounting structure 11 can be a structure arranged on the housing 1, and can be integrally formed with the housing 1, such as integral injection molding. The mounting structure 11 can realize a reliable connection between the support member 3 and the housing 1, and prevent the support member 3 from being separated from the housing 1 due to environmental factors such as vibration. Among them, the length of the first support section 31 can be greater than the distance between the first edge 21 and the second edge 22, so that both ends of the first support section 31 can protrude from the corresponding first edge 21 and the second edge 22, so that the edge of the near field communication substrate 2 can be provided with stable support through the first support section 31, so as to prevent the edge of the near field communication substrate 2 from warping and other deformations, and ensure the distance accuracy between the near field communication substrate 2 and the housing 1.

[0101] In one embodiment, referring to Figure 7 The mounting structure 11 may include a first mounting portion 111 and a second mounting portion 112. Along the first direction X, the first mounting portion 111 and the second mounting portion 112 are respectively located on both sides of the near field communication substrate 2. The first end 311 of the first support segment 31 is clamped to the first mounting portion 111, and the second end 312 of the first support segment 31 is clamped to the second mounting portion 112. The two ends of the first support segment 31 may be connected by the first mounting portion 111 and the second mounting portion 112, respectively, so as to ensure the stability of the first support segment 31 installed on the housing 1, and further ensure the stability of the first support segment 31 supporting the near field communication substrate 2, and ensure the consistency of the distance between each position of the near field communication substrate 2 and the housing 1. In addition, both the first mounting portion 111 and the second mounting portion 112 can be located outside the near-field communication substrate 2, that is, the distance between the first mounting portion 111 and the second mounting portion 112 is greater than the distance between the first edge 21 and the second edge 22 of the near-field communication substrate 2, so that the first mounting portion 111 and the second mounting portion 112 can be respectively used to install and limit the portions of the first support segment 31 protruding from the edge of the near-field communication substrate 2 at both ends, thereby ensuring that the first support segment 31 can provide reliable and stable support for the edge of the near-field communication substrate 2.

[0102] In one embodiment, the first support section 31 may be a cylindrical rod-shaped structure, so that the processing, manufacturing and installation of the first support section 31 can be facilitated, and at the same time, the first support section 31 can be ensured to have a better structural strength, and the reliability of supporting the near field communication substrate 2 can be ensured. In one embodiment, the first support section 31 can also be a flat plate-shaped structure, and the support member 3 has a support surface for supporting the near field communication substrate 2, and the support surface is parallel to the near field communication substrate 2, so that the support surface can be ensured to be completely attached to the near field communication substrate 2, the support area can be increased, and the stability of the support for the near field communication substrate 2 can be ensured.

[0103] Of course, in some other embodiments, the first supporting segment 31 may also have other shapes and structures, such as a prism shape, etc., as long as the stability of the first supporting segment 31 in supporting the near field communication substrate 2 can be guaranteed.

[0104] In one embodiment, taking the first support section 31 as a cylindrical rod-shaped structure as an example, Figure 8 for Figure 7 The cross-sectional view at CC in Figure 8 , the first mounting portion 111 and the second mounting portion 112 may have the same structure. For example, the first mounting portion 111 and the second mounting portion 112 may both include a first claw 11a and a second claw 11b. There is a distance between the first claw 11a and the second claw 11b. The first support segment 31 may be clamped between the first claw 11a and the second claw 11b. The first claw 11a and the second claw 11b may have a variety of shapes. For example, the first claw 11a and the second claw 11b may be in any one or more combinations of straight plate, "C" shape, "L" shape, etc. The first claw 11a and the second claw 11b may clamp the first support segment 31, or the first support segment 31 may be overlapped on the two claws to limit the first support segment 31 in the thickness direction Z of the near field communication substrate 2 between the near field communication substrate 2 and the claws. Therefore, the above-mentioned limiting methods for the first supporting section 31 can ensure that the first supporting section 31 stably supports the near field communication substrate 2 , and ensures that the near field communication substrate 2 and the housing 1 have a high matching accuracy.

[0105] In one embodiment, referring to Figure 8 The first clamping claw 11a includes a first section 11a1, a second section 11a2 and a third section 11a3 which are connected in sequence, and the third section 11a3 can be connected to the housing 1. The first clamping claw 11a and the housing 1 can be integrally formed, that is, the first clamping claw 11a can be formed synchronously during the processing and manufacturing process of the housing 1. In other words, the first clamping claw 11a is an integral structure, and for the sake of convenience of description, the first clamping claw 11a can be divided into three parts, namely, the first section 11a1, the second section 11a2 and the third section 11a3, for exemplary description in this embodiment.

[0106] The distance between the first section 11a1 and the second claw 11b and the distance between the third section 11a3 and the second claw 11b are both greater than or equal to the diameter of the first support section 31, and the distance between the second section 11a2 and the second claw 11b is less than the diameter of the first support section 31. When installing the first support section 31, the first support section 31 can be installed from the position of the third section 11a3 of the first claw 11a to between the first claw 11a and the second claw 11b. Since the distance between the third section 11a3 and the second claw 11b is greater than the diameter of the first support section 31, it is convenient for the first support section 31 to enter between the third section 11a3 and the second claw 11b to avoid interference. Then, since the distance between the second section 11a2 and the second claw 11b is smaller than the diameter of the first support section 31, the first support section 31 can be pressed between the second section 11a2 and the second claw 11b by an appropriate external force, and the first support section 31 can be pushed to the position between the third section 11a3 and the second claw 11b. In this process, the first claw 11a and the second claw 11b can be elastically deformed in the direction away from each other by the support of the first support section 31. Since the distance between the third section 11a3 and the second claw 11b is larger than the diameter of the first support section 31, when the first support section 31 is pressed to the position between the third section 11a3 and the second claw 11b, the second section 11a2 and the second claw 11b are no longer supported by the first support section 31, and the first claw 11a and the second claw 11b are restored to their natural state, so that the first support section 31 can be limited between the third section 11a3 and the second claw 11b. In actual application, the image forming device provided in this embodiment is arranged such that the housing 1, the near field communication substrate 2 and the support member 3 are arranged in order from top to bottom in a direction perpendicular to the ground (see Figure 3), that is, the first support segment 31 is supported at the bottom of the near-field communication substrate 2, and when the first support segment 31 is clamped between the third segment 11a3 and the second clamping claw 11b, the first support segment 31 can overlap the second segment 11a2 by the action of its own gravity, and the sum of the gravity of the first support segment 31 and the gravity of the near-field communication substrate 2 cannot press the first support segment 31 between the second segment 11a2 and the second clamping claw 11b, thereby ensuring that the first support segment 31 is limited between the third segment 11a3 and the second clamping claw 11b, preventing the first support segment 31 from falling off from between the first clamping claw 11a and the second clamping claw 11b. Therefore, by cooperating the first claw 11a and the second claw 11b having the first section 11a1, the second section 11a2 and the third section 11a3, the installation of the first support section 31 can be facilitated. At the same time, at the moment when the first support section 31 is pressed from the position where the second section 11a2 and the second claw 11b are opposite to each other to the position where the third section 11a3 and the second claw 11b are opposite to each other, the force pushing the first support section 31 will drop suddenly, so that the installation status of the first support section 31 can be more easily judged by the change in the operating force.

[0107] In one embodiment, the second claw 11b may also have the same structure as the first claw 11a, and the second claw 11b also has the same first section 11a1, second section 11a2 and third section 11a3 as the first claw 11a, and the first claw 11a and the second claw 11b may be symmetrically distributed, that is, the first section 11a1 of the first claw 11a is opposite to the first section 11a1 of the second claw 11b, and the second section 11a2 of the first claw 11a is opposite to the second section 11a2 of the second claw 11b, and the first claw 11a is opposite to the second section 11a3 of the second claw 11b. The third section 11a3 of the first claw 11a is opposite to the third section 11a3 of the second claw 11b, so that after the first support section 31 is inserted between the third section 11a3 of the first claw 11a and the third section 11a3 of the second claw 11b, the first support section 31 can overlap the second section 11a2 of the first claw 11a and the second section 11a2 of the second claw 11b by its own gravity, so as to ensure the stability of the overlap of the first support section 31, and further ensure the stability of the first support section 31 supporting the near field communication substrate 2. In some other embodiments, the shape and structure of the second claw 11b can also be different from the shape and structure of the first claw 11a, for example, the second claw 11b is flat, "L" shaped, etc., as long as the distance between the second claw 11b and the first section 11a1, the second section 11a2 and the third section 11a3 of the first claw 11a meets the aforementioned distance requirements.

[0108] After one embodiment, refer to Figure 8, when the NFC substrate 2 is supported on the support member 3, there is a gap G between the NFC substrate 2 and the housing 1. The gap G can reserve sufficient installation space for the installation of the support member 3, so that the support member 3 can be smoothly inserted into the position between the third section 11a3 of the first claw 11a and the second claw 11b from the position between the second section 11a2 of the first claw 11a and the second claw 11b, and can be stably supported on the second section 11a2 by the gravity of the support member 3, preventing the support member 3 from falling off the claw. In addition, it can also be achieved that when the support member 3 is inserted into the position between the third section 11a3 and the second claw 11b, the operator can feel the change in the operating force, which is convenient for the operator to judge whether the support member 3 is installed in place.

[0109] In some other embodiments, when the NFC substrate 2 is supported on the support member 3, there may be no gap G between the NFC substrate 2 and the housing 1. After the support member 3 is snapped into place in the corresponding mounting portion, the NFC substrate 2 can be pressed against the housing 1 at the same time. However, this method is likely to cause the local pressure of the NFC substrate 2 to be excessive and deformed, and it is difficult to ensure that the support member 3 can be completely snapped into the position between the third section 11a3 and the second claw 11b. If the support member 3 cannot be completely snapped into the position between the third section 11a3 and the second claw 11b, it is impossible to obtain significant feedback of the change in operating force from the support member 3, and it is difficult for the operator to determine whether the support member 3 is installed in place, which is inconvenient to operate. At the same time, the support member 3 is snapped into the position between the second section 11a2 and the second claw 11b, and the support member 3 is also prone to fall off. Therefore, this embodiment does not limit the situation that there is no gap between the NFC substrate 2 and the housing 1 when the NFC substrate 2 is supported on the support member 3.

[0110] In one embodiment, taking the first support section 31 as a cylindrical rod-shaped structure as an example, when the first support section 31 is supported on the bottom of the near field communication substrate 2, the parts of the near field communication substrate 2 located on both sides of the first support section 31 in the radial direction may rotate with the first support section 31 as the rotation center, which will cause a large change in the distance between the near field communication substrate 2 and the housing 1. For this reason, in this embodiment, referring to Figure 6 and Figure 7, the near field communication substrate 2 may be provided with at least two first limiting holes 24, and the at least two first limiting holes 24 are respectively located on both sides of the first support section 31 in the second direction Y. The shell 1 is provided with at least two first protrusions 12, and the at least two first protrusions 12 are respectively penetrated into a corresponding first limiting hole 24. In other words, the parts located on both sides of the first support section 31 of the near field communication substrate 2 may be provided with first limiting holes 24, and through the cooperation between the first limiting holes 24 and the corresponding first protrusions 12 on the shell 1, the near field communication substrate 2 can be limited at multiple positions, preventing the near field communication substrate 2 from rotating around the first support section 31, and ensuring the consistency of the distance between each position on the near field communication substrate 2 and the shell 1.

[0111] In one embodiment, referring to Figure 6 and Figure 7 , the first limiting hole 24 located on one side of the first supporting section 31 may be a round hole, and the first limiting hole 24 located on the other side of the first supporting section 31 may be a waist-shaped hole. It can be understood that the waist-shaped hole has a length and a width, wherein the length direction of the waist-shaped hole may be the same as the first direction X. For example, during the installation of the near field communication substrate 2 to the housing 1, refer to Figure 7 , a convex rib 14 may be provided on the housing 1, and a gap may be formed between the convex rib 14 and the housing 1. The side of the near field communication substrate 2 having the first edge 21 may be firstly tilted and installed in the gap between the convex rib 14 and the housing 1, and then the side of the near field communication substrate 2 having the second edge 22 may be placed on the housing 1, and at the same time, each first limiting hole 24 is sleeved on the corresponding first protrusion 12. That is to say, the two ends of the near field communication substrate 2 in the first direction X are gradually installed on the housing 1. During this process, the positional relationship between the waist-shaped hole and the first protrusion 12 in the first direction X also changes with the rotation of the near field communication substrate 2, and can finally match. In order to prevent interference and stagnation from occurring during the matching process between the waist-shaped hole and the corresponding first protrusion 12, the length direction of the waist-shaped hole may be consistent with or nearly consistent with the first direction X, and a margin may be reserved for the matching of the waist-shaped hole and the first protrusion 12 in the first direction X, thereby avoiding interference and stagnation between the first protrusion 12 and the first limiting hole 24, and facilitating the installation of the near field communication substrate 2.

[0112] In one embodiment, Fig. 9 A schematic diagram of a partial structure of an image forming device provided by another embodiment of the present application at a viewing angle is shown. Fig.10 This is a schematic diagram of a partial structure of an image forming device provided by another embodiment of the present application at another viewing angle. Fig.11 for Fig. 9 Exploded diagram, see Figures 9 to 11The support member 3 also includes a second support segment 32, one end of which is connected to the first support segment 31, and the extension direction of the second support segment 32 can be different from the extension direction of the first support segment 31, so that the near field communication substrate 2 can be supported over a larger range, ensuring the stability of the support for the near field communication substrate 2.

[0113] Along the second direction Y, the near field communication substrate 2 may further include at least a third edge 23, and the second support segment 32 may include a third end 321, the third end 321 being a portion of the second support segment 32 away from the first support segment 31, and the third end 321 being a structure having a certain length, that is, the third end 321 is a structure extending a certain length from the end surface of the second support segment 32 away from the first support segment 31 in the direction where the first support segment 31 is located. In this embodiment, the third end 321 protrudes from the third edge 23, so that the second support segment 32 can provide stable support for the edge portion of the near field communication substrate 2 in the second direction Y, thereby preventing the edge portion of the near field communication substrate 2 from warping and other deformations, and ensuring the distance accuracy between the near field communication substrate 2 and the housing 1.

[0114] In one embodiment, referring to Fig.10 and Fig.11 The mounting structure 11 connected to the housing 1 may include a third mounting portion 113, and the third end 321 of the second supporting segment 32 is connected to the third mounting portion 113. The third mounting portion 113 is arranged outside the near field communication substrate 2 and is adjacent to the third edge 23 of the near field communication substrate 2. The third end 321 of the second supporting segment 32 can protrude from the third edge 23 and can be mounted in the third mounting portion 113, thereby ensuring reliable support for the edge of the near field communication substrate 2 and preventing warping and deformation.

[0115] In one embodiment, referring to Fig.10 and Fig.11 The third mounting portion 113 is provided with a mounting hole 1131, and the third end 321 of the second support segment 32 is penetrated in the mounting hole 1131, so that the second support segment 32 can be reliably limited through the mounting hole 1131, thereby ensuring the stability of the overall limiting of the support member 3.

[0116] In some other embodiments, the structure of the third mounting portion 113 may be the same as that of the first mounting portion 111 and the second mounting portion 112, and each mounting portion may include the first clamping claw 11a and the second clamping claw 11b described above, which will not be repeated in this embodiment.

[0117] In one embodiment, referring to Fig. 9 and Fig.10, a second limiting hole 25 is provided on the near field communication substrate 2, and the second limiting hole 25 and the second supporting section 32 are respectively located on both sides of the first supporting section 31. A second protrusion 13 is provided on the shell 1, and the second protrusion 13 is penetrated in the second limiting hole 25. Among them, the first supporting section 31 and the second supporting section 32 are both cylindrical rod-shaped structures as an example for explanation. When the first supporting section 31 and the second supporting section 32 are supported on the bottom of the near field communication substrate 2, the part of the near field communication substrate 2 that is located on the same side of the first supporting section 31 as the second supporting section 32 can maintain a stable position accuracy through the support of the second supporting section 32. However, the part of the near field communication substrate 2 that is located on a different side of the first supporting section 31 as the second supporting section 32 cannot be supported by the second supporting section 32, and is prone to rotate with the first supporting section 31 as the rotation center when affected by factors such as vibration and temperature changes, which will cause a large change in the distance between the near field communication substrate 2 and the shell 1. For this reason, in this embodiment, refer to Fig. 9 and Fig.11 The portion of the near field communication substrate 2 that is located on a different side of the first support segment 31 in the second direction Y from the second support segment 32 can be limited by the cooperation of the second limiting hole 25 and the second protrusion 13 on the shell 1, thereby enabling the near field communication substrate 2 to rotate around the first support segment 31 in an effective manner, thereby ensuring the consistency of the distance between each position on the near field communication substrate 2 and the shell 1.

[0118] In some other embodiments, if space permits, there may be a second support segment 32 on both sides of the first support segment 31. For example, the first support segment 31 and the second support segment 32 may form a "cross" shape, or an "X" shape, etc., thereby ensuring the stability of the support for the near field communication substrate 2.

[0119] In one embodiment, taking the first support section 31 and the second support section 32 as a cylindrical rod-shaped structure as an example, the support member 3 including the first support section 31 and the second support section 32 can be an integrally formed structure. As described above, a convex rib 14 can be provided on the housing 1, and a gap can be provided between the convex rib 14 and the housing 1.

[0122] Step S3: Fig.14 This is a state diagram of the near field communication substrate 2 provided in the embodiment of the present application after installation, refer to Fig.14 When the near field communication substrate 2 is rotated to be parallel to the housing 1 , it can be placed on the housing 1 as a whole. At this time, the position accuracy of the near field communication substrate 2 can be ensured by the cooperation of the second limiting hole 25 and the second protrusion 13 .

[0123] Step S4: Fig.15 The state diagram of the support member 3 provided in the embodiment of the present application when it starts to be installed, refer to Fig.15 , the second supporting section 32 of the supporting member 3 is installed toward the third mounting portion 113 in an inclined posture, so that the third end 321 of the second supporting section 32 can be pre-inserted into the mounting hole 1131 of the third mounting portion 113 to achieve pre-positioning.

[0124] Step S5: Fig.16 The state diagram of the support member 3 provided in the embodiment of the present application during the installation process is shown in FIG. Fig.16 After the third end 321 of the second supporting segment 32 is inserted into the mounting hole 1131 of the third mounting portion 113 , the first supporting segment 31 can be installed in the first mounting portion 111 and the second mounting portion 112 .

[0125] Step S6: Fig.17 The state diagram of the support member 3 provided in the embodiment of the present application after installation is shown in FIG. Fig.17 The first end 311 and the second end 312 of the first supporting section 31 can be inserted into the corresponding first mounting portion 111 and the second mounting portion 112 by appropriate external force, thereby completing the assembly operation and achieving support for the near field communication substrate 2 by the supporting member 3.

[0126] In one embodiment, Fig.18 A partial structural diagram of an image forming device provided in another embodiment of the present application, referring to Fig.18As described above, the support member 3 may also be a flat plate structure, and the support member 3 having a flat plate structure may be installed in the mounting structure 11. Exemplarily, the mounting structure 11 may include a column 114, one end of which may be connected to the housing 1, and the other end of the column 114 may be provided with a protrusion 115, the protrusion 115 protrudes toward the side where the near field communication substrate 2 is located, and there is a space between the protrusion 115 and the housing 1 for clamping the support member 3. As described above, the near field communication substrate 2 has a first edge 21, a second edge 22 and a third edge 23, and at least one mounting structure 11 including a column 114 and a protrusion 115 may be provided at positions adjacent to the first edge 21, the second edge 22 and the third edge 23 on the housing 1, and the portions of the support member 3 protruding from the first edge 21, the second edge 22 and the third edge 23 may be clamped with the corresponding mounting structures 11, respectively. When installing the support member 3 to the shell 1, the portion of the support member 3 protruding from the edge of the near-field communication substrate 2 can be pressed into the space between the corresponding protrusion 115 and the shell 1 by appropriate external force, thereby achieving reliable snap-fitting of the support member 3 and facilitating operation.

[0127] In one embodiment, a guide slope 1151 may be provided on one side of the protrusion 115 away from the housing 1. When the support member 3 is pressed into the space between the protrusion 115 and the housing 1 by external force, the guide slope 1151 on the protrusion 115 can provide guidance for the installation of the support member 3.

The guidance of the guide slope 1151 can make it easier for the support member 3 to slide into the space between the protrusion 115 and the housing 1, thereby facilitating the operation.
