Description

Technical Field

[0001] This utility model relates to the field of sheet media processing technology, and in particular to a sheet media processing device. Background Technology

[0002] Existing sheet media processing equipment is used for printing, scanning, magnetic reading / writing, and paper cutting of sheet media such as magnetic tickets, checks, lottery tickets, and bank cards. Correspondingly, sheet media processing equipment includes a printing mechanism, a scanning mechanism, a magnetic reading / writing mechanism, or a paper cutting mechanism. However, in some applications, two operations are required on the sheet media. For example, first, the printing mechanism prints pre-defined information on a check, and then the scanning mechanism scans the check image information for archiving. In such cases, sheet media processing equipment includes both a printing mechanism and a scanning mechanism.

[0003] To reduce costs, related technologies provide a sheet media processing device, which includes a first processing mechanism, a second processing mechanism, and a guiding mechanism. The guiding mechanism is detachably connected between the first and second processing mechanisms. After being processed by the first processing mechanism, the sheet media enters the second processing mechanism through the guiding mechanism for further processing. When only one processing mechanism needs to be used, the guiding mechanism can be detached, allowing either the first or second processing mechanism to be used independently. However, sometimes the widths of the conveying channels for the sheet media to pass through the two processing mechanisms are different. When the width of the conveying channel of the first processing mechanism matches the width of the sheet media, the sheet media is prone to skewing or jamming when entering the conveying channel of the second processing mechanism through the guiding mechanism. Therefore, the compatibility of the existing sheet media processing devices is poor. Utility Model Content

[0004] The purpose of this invention is to provide a sheet media processing device that can be adapted to situations where the width of the conveying channel for sheet media to pass through in two processing mechanisms is different, thereby improving the compatibility of the sheet media processing device.

The first channel plate is used to support the sheet-like medium. The first limiting member and the second limiting member are arranged opposite to each other and spaced apart along the width direction of the sheet-like medium. The first limiting member, the second limiting member, and the first channel plate together form a second conveying channel for conveying the sheet-like medium. Along the width direction of the sheet-like medium, the first limiting member is slidably connected to the first channel plate, and the first limiting member can move relative to the first channel plate to have a first predetermined position and a second predetermined position. When the first limiting member is located at the first predetermined position, the second conveying channel has a first width, which matches the width of the first conveying channel. When the first limiting member is located at the second predetermined position, the second conveying channel has a second width.

The first plug-in is inserted into the first long groove through the opening. Under the action of the elastic force of the first elastic member, the first plug-in always has a tendency to move closer to the second limiting member along the first long groove.

The second conveying channel is formed between the first limiting surface, the second limiting surface, the first channel plate, and the second channel plate.

[0033] The sheet-type media processing device provided by this utility model has at least the following beneficial effects:

[0034] The sheet-like media processing equipment includes a frame, a first processing mechanism, a second processing mechanism, and a guiding mechanism. Both the first and second processing mechanisms are mounted on the frame. The first processing mechanism includes a first conveying channel for conveying the sheet-like media. The second processing mechanism includes a first channel plate, a first limiting member, a second limiting member, and a first elastic member. The first channel plate supports the sheet-like media. The first and second limiting members are positioned opposite each other and spaced apart along the width direction of the sheet-like media.

Along the width direction of the sheet-like media, the first limiting member is slidably connected to the first channel plate, and the first limiting member can move relative to the first channel plate to achieve a first predetermined position. The first limiting member is located at the first predetermined position, and the second conveying channel has a first width that matches the width of the first conveying channel. When the first limiting member is located at the second predetermined position, the second conveying channel has a second width. The first elastic member is connected to the first limiting member, and the elastic force of the first elastic member is used to make the first limiting member always tend to move towards the second predetermined position. The guiding mechanism is detachably mounted on the frame and includes a guiding channel and a first driving unit.

When the guiding mechanism is detached from the frame, the first limiting member moves to the second predetermined position under the action of the first elastic member. The sheet media processing device provided in this embodiment, when the first processing mechanism and the second processing mechanism need to be used simultaneously, connects the first conveying channel of the first processing mechanism and the second conveying channel of the second processing mechanism through the guide channel of the guide mechanism. Furthermore, the first driving part of the guide mechanism cooperates with the first limiting member of the second conveying channel to adjust the width of the second conveying channel to a first width that matches the width of the first conveying channel, thus matching the width of the sheet media and preventing the sheet media from being skewed or jammed within the second conveying channel. When the second processing mechanism needs to be used alone, the guide mechanism is disassembled, and the first limiting member is reset under the action of the first elastic member, restoring the width of the second conveying channel to its original state, i.e., the second conveying channel returns to its second width, ensuring that the second processing mechanism can be used alone. Therefore, the sheet media processing device provided in this embodiment is applicable to situations where the widths of the conveying channels for sheet media in the two processing mechanisms are different, exhibiting strong compatibility.

[0063] Please refer to Figures 1 to 5 This embodiment provides a sheet-like media processing device, which includes a frame 1, a first processing mechanism 2, a second processing mechanism 3, and a guiding mechanism 4. Both the first processing mechanism 2 and the second processing mechanism 3 are mounted on the frame 1. The first processing mechanism 2 includes a first conveying channel 21 for conveying the sheet-like media; the second processing mechanism 3 includes a first channel plate 32, a first limiting member 33, a second limiting member 34, and a first elastic member 35. The first channel plate 32 supports the sheet-like media, and the first limiting member 33 and the second limiting member 34 are along the width direction of the sheet-like media (e.g., ...). Figure 2(As indicated by the arrow ab) are arranged opposite to and spaced apart, the first limiting member 33, the second limiting member 34, and the first channel plate 32 together form a second conveying channel 31 for conveying sheet-like media. Along the width direction of the sheet-like media, the first limiting member 33 is slidably connected to the first channel plate 32, and the first limiting member 33 can move relative to the first channel plate 32 to have a first predetermined position and a second predetermined position. When the first limiting member 33 is in the first predetermined position, the second conveying channel 31 has a first width, which matches the width of the first conveying channel 21. When the first limiting member 33 is in the second predetermined position, the second... The conveying channel 31 has a second width. The first elastic member 35 is connected to the first limiting member 33, and the elastic force of the first elastic member 35 is used to make the first limiting member 33 always tend to move towards the second predetermined position. The guiding mechanism 4 is detachably installed on the frame 1. The guiding mechanism 4 includes a guiding channel 41 and a first driving part 42. When the guiding mechanism 4 is installed on the frame 1, the guiding channel 41 connects the first conveying channel 21 and the second conveying channel 31, and the first driving part 42 drives the first limiting member 33 to move to the first predetermined position. When the guiding mechanism 4 is detached from the frame 1, the first limiting member 33 moves to the second predetermined position under the action of the first elastic member 35.

[0064] The sheet media processing device provided in this embodiment, when the first processing mechanism 2 and the second processing mechanism 3 need to be used simultaneously, connects the first conveying channel 21 of the first processing mechanism 2 and the second conveying channel 31 of the second processing mechanism 3 through the guide channel 41 of the guide mechanism 4 by installing the guide mechanism 4. The first driving part 42 of the guide mechanism 4 cooperates with the first limiting member 33 of the second conveying channel 31 to adjust the width of the second conveying channel 31 to a first width that matches the width of the first conveying channel 21. That is, the width of the second conveying channel 31 matches the width of the sheet media, preventing the sheet media from being skewed or blocked in the second conveying channel 31. When the second processing mechanism 3 needs to be used alone, the guide mechanism 4 is disassembled, and the first limiting member 33 is reset under the action of the first elastic member 35, so that the width of the second conveying channel 31 returns to its original state, that is, the second conveying channel 31 returns to the second width, so that the second processing mechanism 3 can be used alone. Therefore, the sheet media processing device provided in this embodiment can be applied to situations where the widths of the conveying channels for sheet media to pass through the two processing mechanisms are different, and has strong compatibility.

[0065] Optionally, the first processing mechanism 2 includes any one of a printing mechanism, a scanning mechanism, a magnetic reading mechanism, a magnetic writing mechanism, a paper cutting mechanism, and a paper rolling mechanism. The second processing mechanism 3 also includes any one of a printing mechanism, a scanning mechanism, a magnetic reading mechanism, a magnetic writing mechanism, a paper cutting mechanism, and a paper rolling mechanism. In this embodiment, an exemplary solution is provided where the first processing mechanism 2 also includes a printing mechanism, and the second processing mechanism 3 also includes a scanning mechanism. For details, please refer to... Figure 1 The printing mechanism includes a rubber roller 22 and a print head 23, which are tangentially fitted within the first conveying channel 21. The rubber roller 22 is used to drive the sheet-like medium to move within the first conveying channel 21, and the print head 23 is used to print on the surface of the sheet-like medium. The scanning mechanism includes two image sensors 36, which are respectively disposed on both sides of the second conveying channel 31 along the thickness direction of the sheet-like medium. The two image sensors 36 are respectively opposite to the front and back sides of the sheet-like medium within the second conveying channel 31, and are used to scan and acquire image information of the front and back sides of the sheet-like medium.

[0066] Alternatively, please refer to Figure 1 The sheet media processing equipment also includes a paper roll support mechanism 8 fixedly installed on the frame 1. The paper roll support mechanism 8 is used to support the paper roll 9, and the paper roll 9 is used to supply sheet media to the first processing unit 2.

[0067] Alternatively, please refer to Figure 1 The sheet-like media processing equipment also includes multiple conveying roller groups. Each conveying roller group is provided in the first conveying channel 21, the second conveying channel 31, or the guide channel 41. Each conveying roller group includes multiple conveying rollers 5 spaced apart along the conveying direction of the sheet-like media. The conveying roller groups are used to drive the sheet-like media to move.

[0068] Alternatively, please refer to Figure 5 and Figure 8One of the first channel plate 32 and the first limiting member 33 includes a first elongated groove 321 extending along the width direction of the sheet-like medium; the other of the first channel plate 32 and the first limiting member 33 includes a first insertion member 331, which is slidably inserted into the first elongated groove 321. This arrangement, through the cooperation of the first insertion member 331 and the first elongated groove 321, ensures the directional stability of the first limiting member 33 when moving relative to the first channel plate 32, and the position of the first limiting member 33 along the width direction of the sheet-like medium can be adjusted by changing the depth of the first insertion member 331 inserted into the first elongated groove 321. Preferably, the size of the first insertion member 331 matches the width of the first elongated groove 321, so that the first insertion member 331 can only move along the first elongated groove 321, further improving the directional stability of the first limiting member 33 when moving relative to the first channel plate 32. In this embodiment, an exemplary configuration is provided where the first channel plate 32 includes a first elongated groove 321 and the first limiting member 33 includes a first insertion member 331. In other embodiments, the first channel plate 32 may also include a first insertion member 331 and the first limiting member 33 may include a first elongated groove 321. Specifically, the first limiting member 33 includes a first elongated groove 321, and the first insertion member 331 is formed at one end of the first channel plate 32 along the width direction of the sheet-like medium. The first insertion member 331 is inserted into the first elongated groove 321, and the position of the first limiting member 33 along the width direction of the sheet-like medium is adjusted by changing the depth to which the first insertion member 331 is inserted into the first elongated groove 321.

[0069] Alternatively, please refer to Figure 4 The second processing mechanism 3 also includes a limiting component, which includes a limiting groove 391 and a limiting post 392. The limiting groove 391 extends along the width direction of the sheet-like medium and has a set length. The limiting groove 391 is disposed on one of the first limiting member 33 and the first channel plate 32, and the limiting post 392 is disposed on the other of the first limiting member 33 and the first channel plate 32. The limiting post 392 is inserted into the limiting groove 391, and the outer diameter of the limiting post 392 matches the width of the limiting groove 391. When the guiding mechanism 4 is installed on the frame 1, the limiting post 392 is away from the limiting end of the limiting groove 391. When the guiding mechanism 4 is disassembled from the frame 1, the limiting post 392 abuts against the limiting end of the limiting groove 391 under the elastic force of the first elastic member 35. By setting a limiting component, the movement range of the first limiting member 33 is limited, so that when the guide mechanism 4 is installed on the frame 1, the second conveying channel 31 has a first width, and when the guide mechanism 4 is removed from the frame 1, the second conveying channel 31 has a second width, and the size of the second width can be kept stable.

[0070] Alternatively, please refer to Figures 9 to 12In this embodiment, the first width is greater than the second width. That is, during the disassembly of the guide mechanism 4 from the frame 1, the first limiting member 33 gradually approaches the second limiting member 34 under the action of the first elastic member 35 until the first limiting member 33 moves to the second predetermined position. The direction in which the first limiting member 33 approaches the second limiting member 34 is the first direction, specifically as follows: Figures 9 to 12 As indicated by arrow oa; during the installation of the guide mechanism 4 on the frame 1, the first drive unit 42 drives the first limiting member 33 to gradually move away from the second limiting member 34 until the first limiting member 33 moves to the first predetermined position. The direction in which the first limiting member 33 moves away from the second limiting member 34 is the second direction, specifically as shown in the image. Figures 9 to 12 As indicated by the middle arrow ob; in other embodiments, the first width may be smaller than the second width. In this case, during the installation of the guide mechanism 4 on the frame 1, the first drive unit 42 drives the first limiting member 33 to gradually approach the second limiting member 34 until the first limiting member 33 moves to the first predetermined position; during the disassembly of the guide mechanism 4 from the frame 1, the first limiting member 33 gradually moves away from the second limiting member 34 under the action of the first elastic member 35 until the first limiting member 33 moves to the second predetermined position. Preferably, the first elastic member 35 is a tension spring; in other embodiments, the first elastic member 35 may also be a compression spring, etc.

[0071] Alternatively, please refer to Figure 4 , Figure 5 and Figure 8The first channel plate 32 has an opening 322 on one side along the width direction of the sheet-like medium. The first elongated groove 321 communicates with the opening 322. The first limiting member 33 also includes a limiting part 332 and a blocking part 333. The first plug-in member 331 is connected between the limiting part 332 and the blocking part 333. The blocking part 333 is located on the side of the first channel plate 32 away from the limiting part 332. The dimension of the blocking part 333 along the width direction of the first elongated groove 321 is larger than the width of the first elongated groove 321. The first plug-in member 331 communicates with the opening 322. The first insertion member 331 is inserted into the first long groove 321 through the opening 322. Under the action of the elastic force of the first elastic member 35, the first insertion member 331 always has a tendency to move closer to the second limiting member 34 along the first long groove 321. The limiting part 332 includes a first limiting surface 334, and the second limiting member 34 includes a second limiting surface 341. The first limiting surface 334 and the second limiting surface 341 are opposite to each other and spaced apart along the width direction of the sheet-like medium. The second conveying channel 31 is formed between the first limiting surface 334 and the second limiting surface 341. With this configuration, the first connector 331 can be inserted into the first long groove 321 through the opening 322. Then, the first end of the first elastic member 35 is connected to the first limiting member 33, and the second end of the first elastic member 35 is connected to the first channel plate 32. Under the elastic force of the first elastic member 35, the first connector 331 always has a tendency to move along the first long groove 321 towards the second limiting member 34. Therefore, the first connector 331 will not detach from the first channel plate 32 through the opening 322 on the first channel plate 32. Since the size of the blocking part 333 is larger than the width of the first long groove 321, the first connector 331 will not detach from the first channel plate 32 along the thickness direction of the sheet-like medium (that is, the direction perpendicular to the first channel plate 32).

[0072] Alternatively, please refer to Figure 5 and Figure 8 The first channel plate 32 includes a clearance groove 323 and two first long grooves 321. The clearance groove 323 and the two first long grooves 321 all extend along the width direction of the sheet-like medium and are spaced apart along the conveying direction of the sheet-like medium. The two first long grooves 321 are located on both sides of the clearance groove 323. The first limiting member 33 includes a connecting part 335 and two first plug-in parts 331. The connecting part 335 is connected to the limiting part 332 and passes through the clearance groove 323 and extends to the side of the first channel plate 32 away from the limiting part 332. The two first plug-in parts 331 are plugged into the two first long grooves 321 in a one-to-one correspondence. The first elastic member 35 is located on the side of the first channel plate 32 away from the limiting part 332. The first end of the first elastic member 35 is connected to the connecting part 335, and the second end of the first elastic member 35 is connected to the first channel plate 32. This configuration can further improve the stability of the first limiting member 33 moving along the first long groove 321, prevent the first limiting member 33 from deflecting during the movement, and thus ensure accurate positioning of the sheet-like medium.

[0073] Alternatively, please refer to Figure 2 , Figure 6 and Figure 7 The sheet-type media processing device also includes a plug-in assembly, which includes a slot 61 and a second plug-in 62. The slot 61 is disposed on one of the guide mechanism 4 and the frame 1, and the second plug-in 62 is disposed on the other of the guide mechanism 4 and the frame 1. The first limiting member 33 includes a first guide surface 336. When the guide mechanism 4 is installed on the frame 1, the second plug-in 62 is plugged into the slot 61. During the plugging process of the second plug-in 62 into the slot 61, the first driving part 42 abuts against the first guide surface 336 and drives the first limiting member 33 to move towards a first predetermined position. This configuration ensures that the movement direction of the guide mechanism 4 relative to the frame 1 is stable when the guide mechanism 4 is installed on the frame 1. In this embodiment, the sheet-like medium processing device includes two plug-in components. Along the width direction of the sheet-like medium, the two plug-in components are located on both sides of the guide channel 41. The slot 61 is disposed on the guide mechanism 4, and the second plug-in 62 is disposed on the frame 1. In other embodiments, the slot 61 may be disposed on the frame 1, and the second plug-in 62 may be disposed on the guide mechanism 4.

[0074] Alternatively, please refer to Figure 2 , Figures 9 to 12 The guiding mechanism 4 includes a bracket 43. The first driving part 42 has a plate-like structure and is fixedly connected to the bracket 43. The first driving part 42 is opposite to the second limiting member 34 and is spaced apart. The vertical distance between the two is greater than the second width and less than the first width. During the process of the second plug 62 being inserted into the slot 61, the first driving part 42 presses the first guiding surface 336 and causes the first limiting member 33 to move along the second direction.

[0075] Optionally, such as Figures 10 to 12 As shown, the second connector 62 is inserted into the slot 61 along the conveying direction of the sheet-like medium, that is, the slot 61 extends along the conveying direction of the sheet-like medium, and the insertion direction of the guide mechanism 4 and the frame 1 is (e.g.) Figures 10 to 12 The direction indicated by the middle arrow (oc) is consistent with the transport direction of the sheet-like medium; in other embodiments, such as Figure 9 As shown, the second connector 62 and the slot 61 can also be inserted along the width direction of the sheet-like medium, that is, the slot 61 extends along the width direction of the sheet-like medium, and the insertion direction of the guide mechanism 4 and the frame 1 (e.g.) Figure 9 (As indicated by the middle arrow oc) is aligned with the width direction of the sheet-like medium. It should be noted that the insertion direction at this time is also the second direction.

[0076] Optionally, the first guide surface 336 and the first limiting surface 334 are connected at an angle. The first guide surface 336 is an arc-shaped surface or a plane. Along the conveying direction of the sheet-like medium, the first guide surface 336 is located upstream of the first limiting surface 334. The first guide surface 336 is also used to guide the sheet-like medium into the space between the first limiting surface 334 and the second limiting surface 341. With this configuration, the first guide surface 336 can not only be used to cooperate with the first driving unit 42 to drive the first limiting member 33 to move, but also to guide the sheet-like medium into the second conveying channel 31.

[0077] Alternatively, please refer to Figure 3 , Figure 6 and Figure 7 The frame 1 includes a support surface 11 and a receiving groove 12 disposed on the support surface 11. The guide mechanism 4 also includes a support member 44, a support wheel 45, and an elastic element (not shown in the figure). The support member 44 is pivotally connected to the bracket 43 via a first pivot shaft 47. The support wheel 45 is rotatably mounted on the support member 44 and can rotate together with the support member 44 around the axis of the first pivot shaft 47. The elastic element is connected between the bracket 43 and the support member 44. During the insertion process of the guide mechanism 4 and the frame 1, the support wheel 45 can roll along the support surface 11. When the guide mechanism 4 and the frame 1 are inserted into place, the support wheel 45 engages with the receiving groove 12 to lock the relative position of the guide mechanism 4 and the frame 1. The elastic force of the elastic element is used to provide the support member 44 with an elastic force that allows the support member 44 to always rotate around the axis of the first pivot shaft 47 so that the support wheel 45 is embedded in the receiving groove 12. With this configuration, when the guide mechanism 4 is inserted into the frame 1, the support wheels 45 roll along the support surface 11, facilitating the installation of the guide mechanism 4. When the guide mechanism 4 is fully inserted into the frame 1, the support wheels 45 engage with the receiving grooves 12 to ensure the relative position stability of the guide mechanism 4 and the frame 1. Preferably, the guide mechanism 4 includes two support wheels 45 spaced apart along the width direction of the sheet-like medium. During the insertion of the second connector 61 into the slot 61, the two support wheels 45 roll simultaneously on the support surfaces 11 on both sides of the first channel plate 32. Two receiving grooves 12 are spaced apart along the width direction of the sheet-like medium on the support surface 11, with each of the two support wheels 45 corresponding to one of the two receiving grooves 12. When the second connector 62 is fully inserted into the slot 61, the two support wheels 45 are embedded in the two receiving grooves 12, further enhancing the relative position stability of the guide mechanism 4 and the frame 1. More preferably, the elastic element is a torsion spring, and both the support member 44 and the torsion spring are sleeved on the first pivot shaft 47. In other embodiments, the elastic element may also be a compression spring, etc.

[0078] It should be noted that when the guide mechanism 4 needs to be disassembled, the elastic force of the elastic element can be overcome by external force to make the support member 44 rotate in the opposite direction, thereby causing the support wheel 45 to exit the receiving groove 12. Then, the guide mechanism 4 can be moved along the extension direction of the slot 61 to separate the second connector 62 from the slot 61, thus allowing the guide mechanism 4 to be disassembled. Optionally, the bracket 43 is a housing, and the support member 44 is installed inside the housing. The housing has a notch 431, through which the support member 44 is exposed. The operator can turn the support member 44 through the notch 431 to make the support member 44 rotate in the opposite direction against the elastic force of the elastic element.

[0079] Alternatively, please refer to Figure 5 , Figure 11 and Figure 12 The second limiting member 34 is slidably connected to the first channel plate 32 along the width direction of the sheet-like medium, and the second limiting member 34 and the first limiting member 33 are symmetrically arranged about the width center of the second conveying channel 31. The second limiting member 34 can move relative to the first channel plate 32 to have a third predetermined position and a fourth predetermined position. When the first limiting member 33 is in the first predetermined position and the second limiting member 34 is in the third predetermined position, the second conveying channel 31 has a first width; when the first limiting member 33 is in the second predetermined position and the second limiting member 34 is in the fourth predetermined position, ... The second conveying channel 31 has a second width, and the first width is greater than the second width. The second processing mechanism 3 also includes a second elastic member 37, which is connected to the second limiting member 34. The elastic force of the second elastic member 37 is used to ensure that the second limiting member 34 always tends to move towards the fourth predetermined position. The guiding mechanism 4 also includes a second driving part 46. When the guiding mechanism 4 is installed on the frame 1, the second driving part 46 drives the second limiting member 34 to move to the third predetermined position. When the guiding mechanism 4 is removed from the frame 1, the second limiting member 34 moves to the fourth predetermined position under the action of the second elastic member 37. With this configuration, by using the action of installing the guiding mechanism 4, the first driving part 42 of the guiding mechanism 4 cooperates with the first limiting member 33, and the second driving part 46 cooperates with the second limiting member 34 to adjust the width of the second conveying channel 31 to the first width. After the guiding mechanism 4 is removed, the first limiting member 33 is reset under the action of the first elastic member 35, and the second limiting member 34 is reset under the action of the second elastic member 37, so that the width of the second conveying channel 31 is restored to the second width. In addition, the sheet-like media processing equipment adopts a centered design, with the first limiting member 33 and the second limiting member 34 simultaneously approaching the sheet-like media from both sides to prevent the sheet-like media from deflecting.

[0080] In other embodiments, the second limiting member 34 can also be fixedly connected to the first channel plate 32. The sheet-like medium processing device adopts an opposite-side design. The second limiting member 34 is fixed in place, and the first limiting member 33 approaches the sheet-like medium from one side of the sheet-like medium, so that the sheet-like medium is aligned along the second limiting member 34 to avoid skewing.

[0081] Alternatively, please refer to Figure 5 , Figure 11 and Figure 12 In this embodiment, the second limiting member 34 further includes a second guiding surface 342. Along the conveying direction of the sheet-like medium, the second guiding surface 342 is located upstream of the second limiting surface 341. The second guiding surface 342 and the second limiting surface 341 are connected at an angle, and the first guiding surface 336 and the second guiding surface 342 are arranged in a figure-eight shape. The guiding mechanism 4 further includes a second driving part 46. During the process of connecting the guiding mechanism 4 to the frame 1, the second driving part 46 abuts against the second guiding surface 342 and drives the second limiting member 34 to move to a third predetermined position. When the guiding mechanism 4 is connected to the frame 1, the first driving part 42 abuts against the first limiting surface 334, and the second driving part 46 abuts against the second limiting surface 341. When the guiding mechanism 4 is disassembled from the frame 1, the second limiting member 34 moves to a fourth predetermined position under the action of the second elastic member 37. With this configuration, during the insertion of the guide mechanism 4 into the frame 1, the first guide surface 336 cooperates with the first drive unit 42 to drive the first limiting member 33 to move, while the second guide surface 342 cooperates with the second drive unit 46 to drive the second limiting member 34 to move. Furthermore, the first guide surface 336 and the second guide surface 342 are arranged in a V-shape, allowing both to simultaneously guide the sheet-like medium into the second conveying channel 31 from both sides of its width. Preferably, the second guide surface 342 is an arc-shaped surface or a flat surface.

[0082] Alternatively, please refer to Figure 11 and Figure 12 In this embodiment, the second driving part 46 also has a plate-like structure and is fixedly connected to the bracket 43. The first driving part 42 and the second driving part 46 are arranged opposite to each other along the width direction of the sheet-like medium and are spaced apart. The distance between them is greater than the second width and less than the first width. During the process of the guide mechanism 4 being inserted into the frame 1, the first driving part 42 sequentially presses the first guide surface 336 and the first limiting surface 334 to make the first limiting member 33 move along the second direction. The second driving part 46 sequentially presses the second guide surface 342 and the second limiting surface 341 to make the second limiting member 34 move along the first direction.

[0083] Alternatively, please refer to Figure 5One of the first channel plate 32 and the second limiting member 34 includes a second elongated groove 324 extending along the width direction of the sheet-like medium; the other of the first channel plate 32 and the second limiting member 34 includes a third insertion member 343, which is slidably inserted into the second elongated groove 324. This arrangement, through the cooperation of the third insertion member 343 and the second elongated groove 324, ensures the directional stability of the second limiting member 34 relative to the first channel plate 32 during movement, and allows adjustment of the position of the second limiting member 34 along the width direction of the sheet-like medium by changing the depth of the third insertion member 343 inserted into the second elongated groove 324. Preferably, the dimensions of the third insertion member 343 match the width of the second elongated groove 324, so that the third insertion member 343 can only move along the second elongated groove 324, further improving the directional stability of the second limiting member 34 relative to the first channel plate 32 during movement. In this embodiment, the first channel plate 32 includes a second elongated slot 324, and the second limiting member 34 includes a third connector 343. In other embodiments, the first channel plate 32 may include a third connector 343, and the first limiting member 33 may include a second elongated slot 324.

[0084] Alternatively, please refer to Figure 13 The second processing mechanism 3 also includes a second channel plate 38, which is positioned opposite and spaced apart from the first channel plate 32 along the thickness direction of the sheet-like medium. A limiting part 332 is located between the first channel plate 32 and the second channel plate 38. The limiting part 332 also includes a first insertion part 337 and a second insertion part 338. The second conveying channel 31 is formed between the first limiting surface 334, the second limiting surface 341, the first channel plate 32, and the second channel plate 38. The first insertion part 337 and the second insertion part 338 are respectively disposed on both sides of the limiting part 332 along the thickness direction of the sheet-like medium. The first channel plate 32 is provided with a third insertion part 325, and the second channel plate 38 is provided with a fourth insertion part 381. The third insertion part 325 is inserted into the first insertion part 337 along the thickness direction of the sheet-like medium, and the fourth insertion part 381 is inserted into the second insertion part 338 along the thickness direction of the sheet-like medium. With this configuration, by connecting the third connector 325 to the first connector 337, it is possible to prevent the sheet-like medium moving along the second conveying channel 31 from getting stuck in the gap between the limiting part 332 and the first channel plate 32. Similarly, by connecting the fourth connector 381 to the second connector 338, it is possible to prevent the sheet-like medium moving along the second conveying channel 31 from getting stuck in the gap between the limiting part 332 and the second channel plate 38.

[0085] Alternatively, please refer to Figure 13The first insertion portion 337 is one of a first protrusion and a first recess, and the third insertion portion 325 is the other of the first protrusion and the first recess; optionally, the second insertion portion 338 is one of a second protrusion and a second recess, and the fourth insertion portion 381 is the other of a second protrusion and a second recess. In this embodiment, an exemplary configuration is provided where the first insertion portion 337 is a first recess and the third insertion portion 325 is a first protrusion; the second insertion portion 338 is a second recess and the third insertion portion 325 is a second protrusion. Preferably, the first insertion portion 337 includes a plurality of first recesses arranged at intervals along the conveying direction of the sheet-like medium, the second insertion portion 338 includes a plurality of second recesses arranged at intervals along the conveying direction of the sheet-like medium, the third insertion portion 325 includes a plurality of correspondingly arranged first protrusions, and the fourth insertion portion 381 includes a plurality of correspondingly arranged second protrusions. The plurality of first protrusions are inserted into the plurality of first recesses in a one-to-one correspondence, and the plurality of second protrusions are inserted into the plurality of second recesses in a one-to-one correspondence.

[0086] Alternatively, please refer to Figure 7 , Figure 14 and Figure 15 The guiding mechanism 4 also includes a second pivot shaft 50, a fork 48, and a torsion spring 49. The fork 48 is disposed opposite to the first channel plate 32, and a paper ejection channel 7 is formed between the fork 48 and the first channel plate 32. The second pivot shaft 50 is located at the intersection of the guiding channel 41, the paper ejection channel 7, and the second conveying channel 31. The fork 48 is sleeved with the second pivot shaft 50, and the fork 48 can rotate around the axis of the second pivot shaft 50 to have a first position and a second position. When the fork 48 is in the first position, the fork 48 closes the guide outlet 412 of the guiding channel 41 and connects the paper ejection channel 7 with the second conveying channel 31. When the fork 48 is in the second position, the fork 48 closes the entrance of the paper ejection channel 7 and connects the second conveying channel 31 with the guiding channel 41. The torsion spring 49 is sleeved on the second pivot shaft 50 and connected to the fork 48. The torsion of the torsion spring 49 is used to make the fork 48 always have a tendency to rotate towards the first position. Specifically, the guide channel 41 has a guide inlet 411 and a guide outlet 412. The guide inlet 411 is connected to the outlet of the first conveying channel 21. Under no external force, the fork 48 is in the first position. When a sheet-like medium is output from the first conveying channel 21 through the guide channel 41, the sheet-like medium pushes the fork 48 to rotate to the second position, so that the guide outlet 412 is connected to the second conveying channel 31. After the sheet-like medium enters the second conveying channel 31, it can be processed by printing, scanning, etc., and then exited through the paper ejection channel 7.
