Description

Technical Field

[0001] This application relates to the field of image forming technologies, and particularly to an image forming apparatus. Background Art

[0002] Currently, the scanning module and the printing module of a multifunctional all-in-one machine are stacked vertically, and each has a set of paper feeding and discharging mechanisms. For example, the printing module picks up paper from a paper cassette or a manual paper feed cassette, and discharges the paper to a printing paper discharge tray after printing; while the scanning module picks up paper from the paper feed tray of an automatic document feeder, and discharges the paper to a scanning paper discharge tray after scanning. Since the two sets of paper feeding and discharging mechanisms are independent of each other, there is functional redundancy, thus occupying a large space and having a high cost.

[0085] The accompanying drawings here are incorporated into the specification and form a part of this specification, showing embodiments in accordance with the present application, and are used together with the specification to explain the principles of the present application. Detailed implementation manners

[0086] For a better understanding of the technical solutions of the present application, the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0087] It should be clear that the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without making creative efforts belong to the scope of protection of the present application.

[0088] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms of "a", "the" and "said" used in the embodiments of the present application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0089] It should be understood that the term "and / or" used herein is merely a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, in this text, the character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0090] It should be noted that the orientation terms such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described from the perspective shown in the drawings, and should not be construed as a limitation on the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that one component is connected "above" or "below" another component, it can not only be directly connected "above" or "below" another component, but also be indirectly connected "above" or "below" another component through an intermediate component.

[0091] As Figure 1 shown in the schematic diagram of the image forming apparatus 1, the image forming apparatus 1 is a scanning and printing all-in-one machine, including a device body 11 and a scanning module 12 and a printing module 13 installed in the device body 11. The scanning module 12 is placed entirely above the printing module 13 and is electrically connected to the printing module 13.

[0092] Among them, the scanning module 12 includes an automatic document feeder (ADF). When performing a scanning operation, the scanning module 12 can automatically feed paper to complete the scanning. Specifically, the automatic document feeder includes a paper pickup assembly (not shown in the figure), a scanning paper feed tray 12a, a scanning transport assembly (not shown in the figure), and a scanning paper discharge tray 13b. When performing a scanning operation, the user can place the paper to be scanned on the scanning paper feed tray 12a. The paper pickup assembly picks up the paper from the scanning paper feed tray 12a. The paper is transported by the scanning transport assembly through the image reading module to complete image reading, and is discharged to the scanning paper discharge tray 12b.

[0093] The printing module 13 includes a printing paper cassette 13a for storing printing paper, a printing paper feed tray (not shown in the figure), a printing paper discharge tray 13b, and a printing transport assembly (not shown in the figure). When performing a printing operation, the printing module 13 picks up paper from the printing paper feed tray or the printing paper cassette 13a. The paper is transported by the printing transport assembly through the printing path to complete printing, and is discharged to the printing paper discharge tray 13b.

[0094] In the above-mentioned image forming apparatus, a set of paper feed components, a set of transport components, and a set of paper discharge components need to be set separately for the printing module and the scanning module. Therefore, the number of components of the image forming apparatus is large and the functions are redundant, resulting in a large volume and high cost of the image forming apparatus.

[0095] To this end, this embodiment provides an image forming apparatus to solve the above technical problems.

[0096] As Figure 2 shown is a schematic cross-sectional view of the image forming apparatus 1, which includes a device body 11 and a scanning module 12, a printing module 13, a transmission mechanism 14, and a paper separating mechanism 15 installed in the device body 11. The device body 11 is provided with a paper feed tray 111, a first paper discharge tray 112, and a second paper discharge tray 113.

[0097] Among them, the paper feed tray 111 can hold the paper to be scanned or the paper to be printed. The scanning module 12 can read the image information on the paper to be scanned. The printing module 13 can print the image information on the terminal onto the paper to be printed. The transmission mechanism 14 can convey the paper to complete scanning or printing. The paper separating mechanism 15 can receive the paper that has completed scanning or printing, and switch the paper discharge path to discharge the paper that has completed scanning or printing to different paper discharge trays. One of the first paper discharge tray 112 and the second paper discharge tray 113 can receive the paper that has completed scanning, and the other can receive the paper that has completed printing. Hereinafter, a case where the first paper discharge tray 112 receives the paper that has completed scanning and the second paper discharge tray 113 receives the paper that has completed printing will be described as an example.

[0098] Specifically, the user can place the paper to be scanned or printed in the paper feed tray 111 and select the image forming apparatus 1 to execute a scanning operation or a printing operation. The transmission mechanism 14 picks up the paper through the paper feed tray 111 and conveys the paper for scanning or printing. After the paper has completed scanning or printing, the transmission mechanism 14 conveys the paper to the paper separating mechanism 15. At this time, the paper separating mechanism 15 has switched the paper discharge position according to the operation mode selected by the user. The paper separating mechanism 15 can discharge the paper that has completed scanning to the first paper discharge tray 112, or discharge the paper that has completed printing to the second paper discharge tray 113. After the image forming apparatus 1 has completed the operation, the user can take the paper from the first paper discharge tray 112 or the second paper discharge tray 113.

[0099] Please continue to refer to Figure 2 , the image forming apparatus 1 further includes a paper cassette 16 detachably installed on the device body 11, and the paper cassette 16 is used to store the paper for printing. When the image forming apparatus 1 executes a printing operation, the transmission mechanism 14 can also pick up the paper from the paper cassette 16.

[0100] In some embodiments, during the processes of paper printing and scanning, the paper conveyance paths are the same. That is, during the processes of paper printing and scanning, the paper will pass through the scanning module 12 and the printing module 13, so as to simplify the structure of the transmission mechanism 14 and facilitate the miniaturization of the image forming apparatus 1.

[0101] It can be understood that although the paper passes through the scanning module 12 and the printing module 13 during printing or scanning, the image forming apparatus 1 controls the operation of the scanning module 12 or the printing module 13 according to the job mode selected by the user. For example, when the image forming apparatus 1 performs a scanning job, it controls the scanning module 12 to scan the paper and controls the printing module 13 not to work, and the paper only passes through the printing module 13. When the image forming apparatus 1 performs a printing job, it controls the scanning module 12 not to work, the paper only passes through the scanning module 12, and controls the printing module 13 to print on the paper.

[0102] Exemplarily, as Figure 3 FIG. shows a cross-sectional schematic view when the image forming apparatus 1 performs a scanning job, where the black lines represent the paper conveyance path. After the user places the paper to be scanned on the paper feed tray 111 and selects the image forming apparatus 1 to perform a scanning job, the control system of the image forming apparatus 1 controls the paper discharge direction of the paper separating mechanism 15 to face the first paper discharge tray 112. The transport mechanism 14 picks up the paper through the paper feed tray 111 and conveys the paper through the scanning module 12 for image reading. After the paper is scanned, the transport mechanism 14 conveys the paper through the printing module 13 (at this time, the printing module 13 does not work) and transports it to the paper separating mechanism 15, and the paper is discharged along the paper separating mechanism 15 to the first paper discharge tray 112.

[0103] As Figure 4 FIG. shows a cross-sectional schematic view when the image forming apparatus 1 performs a printing job, where the black lines represent the paper conveyance path. When the user selects the image forming apparatus 1 to perform a printing job, the control system of the image forming apparatus 1 controls the paper discharge direction of the paper separating mechanism 15 to face the second paper discharge tray 113. The transport mechanism 14 picks up the paper through the paper cassette 16 or the paper feed tray 111 and conveys the paper through the scanning module 12 (at this time, the scanning module 12 does not work) and transfers it to the printing module 13 for printing. After the paper is printed, the transport mechanism 14 conveys the paper to the paper separating mechanism 15, and the paper is discharged along the paper separating mechanism 15 to the second paper discharge tray 113.

[0104] Among them, in some embodiments, when the image forming apparatus 1 performs a printing job, it can control the transport mechanism 14 to preferentially pick up paper from the paper pickup tray. When the transport mechanism 14 senses that there is no paper in the paper pickup tray, it controls the transport mechanism 14 to pick up paper from the paper cassette 16.

[0105] In this embodiment, when the image forming apparatus 1 performs scanning and printing operations, a single paper feed tray 111 is shared, reducing the number of paper feed trays 111. When the image forming apparatus 1 performs scanning and printing operations, the paper conveyance path is the same, and a single transport mechanism 14 can be shared, simplifying the number of transport mechanisms 14 and making the structure compact, effectively reducing the volume of the image forming apparatus 1. Additionally, after the paper has completed scanning or printing, the paper separation mechanism 15 can discharge the paper into the corresponding paper discharge tray to prevent the paper that has completed scanning and the paper that has completed printing from being finally discharged into the same paper discharge tray, causing paper confusion.

[0106] As Figure 5 and Figure 6 shown in the schematic diagrams of the paper separation mechanism 15 in different paper discharge positions, the paper separation mechanism 15 includes a guide member 151. The guide member 151 is rotatably connected to the apparatus main body 11, and the control system of the image forming apparatus 1 can control the guide member 151 to rotate to a first guiding position or a second guiding position. Among them, Figure 5 is a schematic diagram of the guide member 151 in the first guiding position. When the user selects the image forming apparatus 1 to perform a scanning operation, the guide member 151 is controlled to be in the first guiding position. At this time, the guide member 151 is correspondingly arranged with the first paper discharge tray 112, and the guide member 151 can guide the paper to be discharged into the first paper discharge tray 112. Figure 6 is a schematic diagram of the guide member 151 in the second guiding position. When the user selects the image forming apparatus 1 to perform a printing operation, the guide member 151 is controlled to be in the second guiding position. The guide member 151 is correspondingly arranged with the second paper discharge tray 113, and the guide member 151 can guide the paper to be discharged into the second paper discharge tray 113.

[0107] In this embodiment, by the user selecting the image forming apparatus 1 to perform a scanning operation or a printing operation, the guiding position of the guide member 151 is adjusted, thereby controlling the paper to be discharged into the first paper discharge tray 112 or the second paper discharge tray 113, facilitating the user to pick up the paper and avoiding the confusion problem when the printed paper and the scanned paper are discharged into the same paper discharge tray.

[0108] Furthermore, please continue to refer to Figure 5 and Figure 6 , the paper separation mechanism 15 further includes a first support member 152 and a second support member 153. The first support member 152 is correspondingly arranged with the first paper discharge tray 112, and the second support member 153 is correspondingly arranged with the second paper discharge tray 113. In the first guiding position, the guide member 151 is aligned with the first support member 152, and the guide member 151 can guide the paper to be discharged along the first support member 152 into the first paper discharge tray 112. In the second guiding position, the guide member 151 is aligned with the second support member 153, and the guide member 151 can guide the paper to be discharged along the second support member 153 into the second paper discharge tray 113.

[0109] In this embodiment, by providing the first support member 152 and the second support member 153, the structure of the guide member 151 can be reduced, and the guide and support functions for paper conveyance are achieved, ensuring the stability during paper conveyance.

[0110] Please refer to Figures 3 to 6 , in some embodiments, the first paper discharge tray 112 can be provided at the side end of the device body 11, and the second paper discharge tray 113 can be provided at the upper end of the device body 11. Correspondingly, the first support member 152 is provided in a horizontal state. When the guide member 151 is in the first guiding position, the guide member 151 is provided in a horizontal state to guide the paper to move linearly along the first support member 152 to the first paper discharge tray 112. The second support member 153 is provided in an inclined state (for example, the second support member 153 forms an angle of 45° with the horizontal plane). When the guide member 151 is in the second guiding position, the guide member 151 is provided in an inclined state to guide the paper to rotate its direction here and then discharge it to the second paper discharge tray 113.

[0111] Please continue to refer to Figure 3 and Figure 4 , along the paper conveyance direction, in the scanning module 12 and the printing module 13, the part where the paper passes through first is set at the upstream position, and the part where the paper passes through later is set at the downstream position. Specifically, the scanning module 12 can be provided upstream of the printing module 13. Alternatively, along the paper conveyance direction, the scanning module 12 can be provided downstream of the printing module 13. Preferably, when the scanning module 12 is provided upstream of the printing module 13 along the paper conveyance direction, it is beneficial for the image forming device 1 to perform operations such as copying (scanning first and then printing), simplifying the paper conveyance path.

[0112] Please continue to refer to Figure 3 and Figure 4 , the transmission mechanism 14 includes a plurality of rollers distributed on the paper conveyance path to transfer the paper. Among them, the rollers at least include a first roller 141, a second roller 142, a third roller 143, a fourth roller 144, and a fifth roller 145. The first roller 141 is close to the paper cassette 16, the second roller 142 is close to the scanning module 12, the third roller 143 is provided between the scanning module 12 and the printing module 13, the fourth roller 144 is provided between the printing module 13 and the paper separation module, and the fifth roller 145 is provided between the paper separation mechanism 15 and the second paper discharge tray 113.

[0113] Specifically, when the image forming device 1 performs a scanning operation, paper is taken from the paper feed tray 111 to the second roller 142, the second roller 142 conveys the paper to the scanning module 12, the third roller 143 conveys the scanned paper to the printing module 13, and the fourth roller 144 conveys the paper passing through the printing module 13 to the paper separation mechanism 15.

[0114] When the image forming apparatus 1 executes a printing job, paper is taken from the paper feed tray 111 to the second roller 142 (alternatively, paper is taken from the paper cassette 16 to the first roller 141, and the second roller 142 conveys the paper to the second roller 142). The second roller 142 conveys the paper to the scanning module 12, the third roller 143 conveys the paper passing through the scanning module 12 to the printing module 13, the fourth roller 144 conveys the printed paper to the paper separating mechanism 15, and the fifth roller 145 discharges the paper passing through the paper separating mechanism 15 to the second paper discharge tray 113.

[0115] In some embodiments, the number of rollers can be increased according to the distances between various components and other circumstances, and it can be specifically set according to actual situations. This embodiment does not limit it here.

[0116] As Figure 7 shown is a schematic diagram of the scanning module 12 installed in the device body 11. The scanning module 12 includes a mounting frame 121 and a scanning component 122. The mounting frame 121 is installed inside the device body 11. The mounting frame 121 is provided with a cavity 121a, and the scanning component 122 is detachably installed in the cavity 121a so as to facilitate taking out the scanning component 122 from the device body 11 for cleaning or maintenance.

[0117] Among them, the mounting frame 121 is provided with a light-shielding cover 121b. The light-shielding cover 121b can cover the cavity 121a to shield external light sources and improve the quality of the scanned image. Along the paper conveying direction, one end of the light-shielding cover 121b is rotatably installed on the mounting frame 121 to rotate the light-shielding cover 121b to open and close the cavity 121a, so as to facilitate the installation and disassembly of the scanning component 122. The other end of the light-shielding cover 121b is snap-connected to the mounting frame 121 to ensure that the scanning component 122 is stably arranged inside the mounting frame 121.

[0118] As Figure 8 shown is a cross-sectional view of the scanning module 12. As Figure 9 shown is an exploded schematic diagram of the scanning module 12. Please refer to Figure 8 and Figure 9 . In the mounting frame 121 and the scanning component 122, one is provided with a limiting groove 121d, and the other is provided with a limiting slider 121c. By the cooperation of the limiting groove 121d and the limiting slider 121c, the position of the scanning component 122 is limited.

[0119] In some embodiments, the mounting frame 121 is provided with a limiting slider 121c, and the scanning component 122 is provided with a limiting groove 121d. The limiting slider 121c can slide along the limiting groove 121d, so that the scanning component 122 is installed into the mounting frame 121 through the sliding cooperation of the limiting slider 121c and the limiting groove 121d.

[0120] Alternatively, in some embodiments, the mounting bracket 121 is provided with a limiting groove 121d, and the scanning assembly 122 is provided with a limiting slider 121c, which can be specifically set according to actual situations, and this embodiment does not limit this.

[0121] Among them, as Figure 10 shown is Figure 9 the enlarged schematic view of part A (limiting slider 121c) in Figure 11 and Figure 9 the enlarged schematic view of part B (limiting groove 121d) in Figure 10 and Figure 11 are combined for reference. Along the paper conveying direction, the limiting slider 121c is provided with limiting portions 121c1 protruding toward both sides. Correspondingly, the side wall of the limiting groove 121d is provided with a mating portion 121d1 recessed inward, and the limiting portion 121c1 cooperates with the mating portion 121d1. Through the cooperation of the limiting portion 121c1 and the mating portion 121d1, the up-and-down movement of the scanning assembly 122 relative to the mounting bracket 121 is restricted to ensure that the paper stably passes through the scanning assembly 122.

[0122] Specifically, please continue to refer to Figure 8 . Along the direction perpendicular to the paper conveying direction, the cross-sections of the limiting slider 121c and the limiting groove 121d can both be in a "T" shape structure to ensure the stability of the cooperation between the scanning assembly 122 and the mounting bracket 121.

[0123] Please continue to refer to in combination Figure 8 and Figure 9 . The scanning assembly 122 can be a double-sided contact image sensor (Contact Image Sensor, CIS). Specifically, the scanning assembly 122 includes an upper housing 122a, a lower housing 122b, an upper scanning member 122c, a lower scanning member 122d, an upper elastic member 122e, and a lower elastic member 122f. The upper housing 122a and the lower housing 122b are connected to form a connected mounting cavity 122b1, a scanning paper inlet 122b2, and a scanning paper outlet 122b3.

[0124] The upper scanning member 122c and the lower scanning member 122d are installed in the mounting cavity 122b1, and a scanning channel 122d1 is formed between the upper scanning member 122c and the lower scanning member 122d. The scanning paper inlet 122b2 and the scanning paper outlet 122b3 are respectively located on both sides of the scanning channel 122d1, so that the paper can enter the scanning channel 122d1 through the scanning paper inlet 122b2 and be discharged through the scanning paper outlet 122b3.

[0125] Correspondingly, the mounting bracket 121 is provided with a paper feeding channel 121e communicating with the scanning paper feeding port 122b2 and a paper discharging channel 121f communicating with the scanning paper discharging port 122b3. The paper can enter the scanning channel 122d1 through the scanning paper feeding channel 121e and the paper feeding port 122b2, and be discharged through the scanning paper discharging port 122b3 and the paper discharging channel 121f.

[0126] The upper elastic member 122e is disposed between the upper scanning member 122c and the inner top wall of the upper housing 122a, and the lower elastic member 122f is disposed between the lower scanning member 122d and the inner bottom wall of the lower housing 122b. Under the elastic force of the upper elastic member 122e and the lower elastic member 122f, the upper scanning member 122c and the lower scanning member 122d are pressed against each other, ensuring the stability of the size of the scanning channel 122d1 between the upper scanning member 122c and the lower scanning member 122d.

[0127] Wherein, along the direction perpendicular to the conveying direction of the paper, the two end edge positions of the upper scanning member 122c are slightly higher than the middle position, and the two end edge positions of the lower scanning member 122d are slightly higher than the middle position. Under the elastic force of the upper elastic member 122e and the lower elastic member 122f, the two end edge positions of the upper scanning member 122c are abutted against the two end edge positions of the lower scanning member 122d, and a gap is left between the middle position of the upper scanning member 122c and the middle position of the lower scanning member 122d to form the scanning channel 122d1, avoiding the pressure exerted by the upper elastic member 122e and the lower elastic member 122f on the upper scanning member 122c and the lower scanning member 122d, resulting in direct contact between the upper scanning member 122c and the lower scanning member 122d and the paper being unable to pass through the scanning module 12.

[0128] In some embodiments, both the upper elastic member 122e and the lower elastic member 122f can be springs.

[0129] In some embodiments, the upper housing 122a and the lower housing 122b are detachably connected, facilitating the removal of the upper scanning member 122c and the lower scanning member 122d from the installation cavity 122b1 for cleaning and maintenance. Among them, the connection position of the upper housing 122a and the lower housing 122b is arranged to avoid the scanning channel 122d1.

[0130] Specifically, the upper housing 122a and the lower housing 122b can be in snap-fit. Alternatively, one end of the upper housing 122a and one end of the lower housing 122b can be hinged, and the other end of the upper housing 122a and the other end of the lower housing 122b can be in snap-fit.

[0131] 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, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
