Description

Technical Field

[0001] The present application relates to the technical field of image formation, and particularly relates to an image forming apparatus. Background Art

[0002] An image forming apparatus is a device that forms an image on a printing medium according to an input signal, such as a printer, a copier, a fax machine, and a multifunctional printer integrating printer, copier, and fax functions. The electrical control in the image forming apparatus is mainly carried out through a control board and a high-voltage board. The control board is connected to a memory, and information such as the service life and related parameters of the image forming apparatus is stored in the memory.

[0003] For a large image forming apparatus (such as a printer suitable for A3 paper size), due to its large space, the memory can be stacked on the control board or placed side by side with the control board to facilitate the signal connection between the memory and the control board. For a small image forming apparatus (such as a printer suitable for A4 paper size), due to its small space, the control board and the high-voltage board are respectively arranged on both sides of the image forming apparatus, and the memory is arranged near the high-voltage board, so that the distance between the memory and the control board is relatively far, and it is difficult to establish communication between the two and there is signal interference.

[0004] Therefore, there is a problem in the existing small image forming apparatus that it is difficult to layout the control board and the memory. Utility Model Content

[0005] The present application provides an image forming apparatus for solving the problem that it is difficult to layout the circuit board and the memory in a small image forming apparatus.

[0006] An image forming apparatus provided by an embodiment of the present application includes: a body, a printing medium can move in the body to form an image on the printing medium, and a frame is provided in the body; a first circuit board, the first circuit board is arranged on one side of the body; a memory, installed on one side of the frame close to the first circuit board, and the memory is electrically connected to the first circuit board.

[0007] In a possible design, on both sides of the body in the moving direction of the printing medium are a driving side and a non-driving side respectively, a laser unit is provided in the body, and the laser unit and the memory are both installed on the frame.

[0008] In a possible design, the image forming apparatus includes a mounting seat, and the memory is installed on the frame through the mounting seat.

[0009] In a possible design, the mounting seat includes: a mounting portion and a fixing portion, the memory is installed on the mounting portion, and the fixing portion is connected to the frame.

[0010] In a possible design, the fixing parts are arranged on both sides of the mounting part, and the fixing parts are provided with mounting holes, and a connecting piece passes through the mounting holes to be connected with the frame.

[0011] In a possible design, the mounting part includes: a clamping wall and a first limiting wall. The clamping wall can limit the movement of the memory along the height direction of the machine body, and the first limiting wall can limit the movement of the memory along the direction perpendicular to the height direction of the machine body.

[0012] In a possible design, the two clamping walls are arranged oppositely, and / or the two first limiting walls are arranged oppositely.

[0013] In a possible design, there is a gap between the clamping wall and the first limiting wall, and the connecting line between the first circuit board and the memory passes through the gap.

[0014] In a possible design, the mounting part further includes a second limiting wall, and the second limiting wall is connected to the first limiting wall and extends along different directions.

[0015] In a possible design, the image forming device further includes a second circuit board, and the second circuit board and the first circuit board are respectively arranged on the surfaces on both sides of the machine body in the moving path direction of the printing medium.

[0016] In the present application, the memory is arranged close to the first circuit board, and the distance between them is relatively short, which is convenient for establishing communication between them. And because the transmission distance between the memory and the first circuit board is short, the signal is less affected by external interference during transmission, and the accuracy and reliability of signal transmission are relatively high. The first circuit board and the memory are arranged on different surfaces of the machine body, which can make better use of the space of the image forming device, so that the volume of the image forming device is small. At the same time, the first circuit board and the memory are relatively independent. When it is necessary to repair the memory or obtain information from the memory, the operator will not contact the first circuit board, reducing the damage probability of the first circuit board.

[0017] Furthermore, both the first circuit board and the memory are located on the surface of the machine body, and the connecting line between them is also located on the surface of the machine body, so as to reduce the interference of the components inside the machine body on the communication between the first circuit board and the memory, and reduce the interference of the communication between the first circuit board and the memory on the components inside the machine body, thereby improving the imaging quality and imaging stability of the image forming device.

[0052] The accompanying drawings here are incorporated into and form a part of this specification, showing embodiments consistent with this application, and are used together with the specification to explain the principles of this application. Detailed implementation manners

[0053] For a better understanding of the technical solutions of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0054] It should be clear that the described embodiments are only a part rather than all of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts belong to the scope of protection of this application.

[0055] The terms used in the embodiments of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The singular forms "a", "the" and "said" used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0056] It should be understood that the term " / and" used herein is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " herein generally represents an "or" relationship between the associated objects before and after.

[0057] It should be noted that the orientation terms such as "upper", "lower", "left", and "right" described in the embodiments of this application are described from the angles shown in the accompanying drawings and should not be construed as a limitation on the embodiments of this application. In addition, in the context, it should also be understood that when it is mentioned that an element is connected "above" or "below" another element, it can not only be directly connected "above" or "below" another element, but also be indirectly connected "above" or "below" another element through an intermediate element.

[0058] The image forming apparatus can be a printer, a copier, a fax machine, or a multifunction printer integrating the functions of a printer, a copier, and a fax machine. Figure 1 The structure of an image forming apparatus is shown. As Figure 1 shown, the image forming apparatus has a main body 10, and a supply unit 20, a conveyance unit 30, a transfer unit 40, a laser unit 50, and a fixing unit 60 are provided inside the main body 10.

[0059] Specifically, when the image forming apparatus 1 performs an imaging operation, first, the print media stacked in the supply unit 20 are separated one by one and conveyed to the transfer unit 40 through the conveyance unit 30. The laser unit 50 converts the received image information into a light beam and irradiates it onto the imaging component 41 in the transfer unit 40 to form an electrostatic latent image. The electrostatic latent image allows toner (developer) to adhere to the electrostatic latent image area on the imaging component 41 through the electrostatic principle to generate a toner image.

[0060] Among them, there are four imaging components 41, and the four imaging components 41 respectively correspond to the formation of images of four colors YMCK (Y: yellow, M: magenta, C: cyan, K: black).

[0061] As the intermediate transfer belt 43 passes through the four imaging components 41 in sequence, the toner images of the four colors are sequentially transferred onto the intermediate transfer belt 43 under the clamping of the primary transfer roller 42 and the imaging component 41 to complete one transfer. The intermediate transfer belt 43 conveys the toner image to the secondary transfer roller 44. When the print media passes through the clamping area between the secondary transfer roller 44 and the intermediate transfer belt 43, the toner image is transferred onto the print media. The print media with the toner image is further conveyed to the fixing unit 60. After the heating roller 61 and the pressure roller 62 in the fixing unit 60 firmly fix the toner image on the print media, the print media is discharged.

[0062] In a specific embodiment, as Figure 2 and Figure 3 shown, the image forming apparatus further includes: a first circuit board 1 and a memory 2. The first circuit board 1 is disposed on one surface of the main body 10 on the side in the moving path direction of the print media, and the memory 2 is disposed on one side close to the first circuit board 1 on the surface of the main body 10 above the moving path direction of the print media. The memory 2 is electrically connected to the first circuit board 1.

[0063] The first circuit board 1 is generally a PCB board for controlling the operation of the image forming apparatus; the memory 2 is generally an Electrically Erasable Programmable Read Only Memory (EEPROM) for storing information of the image forming apparatus.

[0064] In this embodiment, asFigure 2 and Figure 3 As shown, the memory 2 is arranged close to the first circuit board 1, and the distance between the two is short, which facilitates the establishment of communication between the two. Moreover, since the transmission distance between the memory 2 and the first circuit board 1 is short, the signal is less subject to external interference during the transmission process, and the accuracy and reliability of the signal transmission are high. The first circuit board 1 and the memory 2 are arranged on different surfaces of the body 10, which can better utilize the space of the image forming device and make the image forming device smaller in size. At the same time, the first circuit board 1 and the memory 2 are relatively independent. When the memory 2 needs to be repaired or information is obtained from the memory 2, the operator will not contact the first circuit board 1, which reduces the probability of damage to the first circuit board 1.

[0065] Furthermore, the first circuit board 1 and the memory 2 are both located on the surface of the body 10, and the connection between the two is also located on the surface of the body 10, thereby reducing the interference of components inside the body 10 on the communication between the first circuit board 1 and the memory 2, and reducing the interference of the communication between the first circuit board 1 and the memory 2 on the components inside the body 10, thereby improving the imaging quality and imaging stability of the image forming device.

[0066] Specifically, the body 10 has a driving side 11 and a non-driving side 12 on both sides of the moving direction of the printing medium. The driving side 11 is provided with a power source for driving rotating components such as the imaging component 41 and the primary transfer roller 42, and the non-driving side 12 is opposite to the driving side 11.

[0067] More specifically, the laser unit 50 is disposed between the driving side 11 and the non-driving side 12 , the body 10 has a frame 13 for mounting the laser unit 50 , and the memory 2 is mounted on the frame 13 .

[0068] Furthermore, Figure 3 and Figure 4 As shown, the image forming apparatus includes a mounting seat 3, and the memory 2 is mounted on the frame 13 through the mounting seat 3. Since the frame 13 is a sheet metal part, it is difficult to directly fix the memory 2 on the sheet metal part, so the installation through the mounting seat 3 can reduce the difficulty of installing the memory 2, and the mounting seat 3 can protect the memory 2, so that the memory 2 is not easily affected by external impact.

[0069] Specifically, Figure 5 As shown, the mounting seat 3 includes: a mounting portion 31 and a fixing portion 32, the memory 2 is mounted on the mounting portion 31, and the fixing portion 32 is connected to the frame 13. The mounting portion 31 has an installation space, and the memory 2 is installed in the installation space.

[0070] More specifically, two fixing parts 32 are arranged on both sides of the mounting part 31, so that the fixing points of the mounting base 3 and the frame 13 are located on both sides of the mounting part 31, improving the connection stability between the mounting base 3 and the frame 13. Optionally, the fixing part 32 is provided with a mounting hole 321, and the connecting piece 4 passes through the mounting hole 321 to be connected with the frame 13. Among them, the connecting piece 4 can be a fastening piece such as a screw.

[0071] It can be understood that there can also be three fixing parts 32 arranged along the circumferential direction of the mounting part 31, or four fixing parts 32 arranged along the circumferential direction of the mounting part 31.

[0072] It can be understood that the fixing part 32 can also be connected to the frame 13 by means of bonding, welding, etc.

[0073] In a specific embodiment, as Figure 5 shown, the mounting part 31 includes: a clamping wall 311 and a first limiting wall 312. The clamping wall 311 can limit the movement of the memory 2 along the height direction of the machine body 10, and the first limiting wall 312 can limit the movement of the memory 2 along the direction perpendicular to the height direction of the machine body 10.

[0074] In this embodiment, as Figure 5 shown, the clamping wall 311 abuts against the top wall of the memory 2 to limit the movement of the memory 2 along the height direction of the machine body 10. The clamping wall 311 and the first limiting wall 312 respectively abut against different side walls of the memory 2 to limit the movement of the memory 2 along the direction perpendicular to the height direction of the machine body 10, thereby realizing the fixation of the memory 2.

[0075] Specifically, the clamping wall 311 includes an extension part and a hook part. The hook part is arranged at one end of the extension part away from the fixing part 32. The extension part abuts against the side wall of the memory 2, and the hook part abuts against the top wall of the memory 2.

[0076] It can be understood that both the clamping wall 311 and the first limiting wall 312 have a certain elasticity (able to undergo elastic deformation), so as to facilitate the installation of the memory 2.

[0077] Specifically, as Figure 5 shown, two clamping walls 311 are arranged oppositely, and / or two first limiting walls 312 are arranged oppositely. That is, two clamping walls 311 and two first limiting walls 312 are arranged staggeredly to enclose a mounting space, so that the two clamping walls 311 respectively abut against two opposite side walls of the memory 2, and the two first limiting walls 312 respectively abut against the other two opposite side walls of the memory 2.

[0078] More specifically, as Figure 5As shown, there is a gap between the snap-in wall 311 and the first limiting wall 312, and the connection line between the first circuit board 1 and the memory 2 passes through the gap. By providing this gap, wiring is facilitated, and at the same time, the gap can limit the connection line.

[0079] Furthermore, as Figure 5 shown, on the side of the first limiting wall 312 facing the memory 2, there are protruding ribs 312a. The protruding ribs 312a are in contact with the memory 2 to prevent the side wall of the memory 2 from not fitting well with the first limiting wall 312, resulting in shaking and abnormal noise. Among them, multiple protruding ribs 312a are arranged at intervals on the first limiting wall 312, and the protruding ribs 312a extend along the height direction of the machine body 10.

[0080] Even further, as Figure 5 shown, some of the memories 2 are not regular in shape, and there are depressions on the memories 2. The mounting portion 31 further includes a second limiting wall 313. The second limiting wall 313 is connected to the first limiting wall 312 and extends in different directions, so that the second limiting wall 313 can penetrate into the depression and be in contact with the memory, thereby better fixing the memory 2.

[0081] In the above embodiments, as Figure 2 shown, the image forming apparatus further includes a second circuit board 5. The second circuit board 5 and the first circuit board 1 are respectively arranged on both sides of the machine body 10 in the moving path direction of the printing medium, so that the distance between the second circuit board 5 and the first circuit board 1 is relatively far, and the distance between the second circuit board 5 and the memory 2 is also relatively far. Thus, the second circuit board 5 does not interfere with the signal transmission between the first circuit board 1 and the memory 2, and improves the accuracy of the signal transmission between the first circuit board 1 and the memory 2. Among them, the second circuit board 5 is a high-voltage board for providing high voltage to the machine body 10.

[0082] Specifically, the first circuit board 1 is arranged on the driving side 11 of the machine body 10, and the second circuit board 5 is arranged on the non-driving side 12 of the machine body 10.

[0083] More specifically, the first circuit board 1 and the second circuit board 5 are respectively arranged on the driving side 11 and the non-driving side 12 of the machine body 10, making better use of the space on both sides of the machine body 10 and more reasonably realizing the layout of the first circuit board 1, the memory 2 and the second circuit board 5 in the image forming apparatus.

[0084] Furthermore, since the first circuit board 1, the memory 2 and the second circuit board 5 are all arranged on the surface of the machine body 10, it is convenient for the installation, maintenance and disassembly of the first circuit board 1, the memory 2 and the second circuit board 5.

[0085] Further, the first circuit board 1 can be connected to the body 10 by means of fasteners, adhesion, snap connection, welding or other connection methods, and the second circuit board 5 can also be connected to the body 10 by means of fasteners, adhesion, snap connection, welding or other connection methods.

[0086] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
