Description

Technical Field

[0001] This utility model relates to the field of printer technology, and in particular to an image reading device and printer. Background Technology

[0002] To meet the needs of office printing and copying, multifunction printers that integrate printing, copying, and scanning are becoming increasingly popular. Compared to printers with only printing capabilities or scanners with only scanning capabilities, users generally prefer printers that combine these functions. Image reading devices typically enable continuous multi-page scanning, with a relatively flat "C"-shaped scanning path. When paper jams occur during scanning, the short distance and opposite directions of the paper feed and output paths cause the original document to bend significantly. Furthermore, the image reading device exerts a certain clamping force on the original, making it difficult to remove the jammed document. This is especially true for smaller originals, which are more prone to tearing, negatively impacting the user experience. Utility Model Content

[0003] This invention provides an image reading device and printer, the purpose of which is to reduce the difficulty of retrieving original documents stuck in the image reading device.

[0004] To achieve the above objectives, this utility model provides an image reading device, comprising:

[0006] The output tray is configured to hold the read original document;

[0007] The main body of the device is configured to read the original document and provide a transmission path for the original document, and output the read original document to the output tray. The main body of the device has a support surface and a mounting hole on one side along the first direction. The support surface is configured to support the connector. The connector is rotatably connected to the main body of the device through the mounting hole, so that the tray body has a state of being relatively stationary with respect to the main body of the device and a state of rotating relative to the main body of the device with respect to the axis of rotation of the mounting hole.

[0008] In one embodiment, the support surface includes an interconnected support sub-surface and a clearance surface, the support sub-surface being configured to support the connector, and the clearance surface being inclined relative to the support sub-surface to provide the device body with clearance space to allow the connector to rotate.

[0009] In one embodiment, the connector includes an abutment surface and a limiting corner connected to each other on the side near the support surface. When the tray body supports the original document, the abutment surface abuts against the support surface. When the paper feed tray rotates relative to the device body, the limiting corner abuts against the clearance surface to limit the paper feed tray.

[0010] In one embodiment, the device body has the supporting surface and the mounting hole on both opposite sides along the first direction, and the tray body is connected to the connector on both opposite sides along the first direction.

[0011] In one embodiment, the tray body includes a first tray and a second tray, the first tray being connected to the device body via the connector, and the second tray being slidably connected to the first tray.

[0012] In one embodiment, the first tray has a stop that protrudes toward the second tray, the stop being configured to limit the range of movement of the second tray relative to the first tray.

[0013] In one embodiment, the first tray has a protrusion that projects toward the second tray and is capable of abutting against the second tray.

[0014] In one embodiment, the device body includes a housing, which can open and close the body. The inner wall of the housing is provided with a guide for guiding the original document. When the housing is closed, it forms an original document transmission path with the device body.

The connecting shaft is rotatably engaged in a guide rib of the housing, and the first rod and the second rod are respectively connected to its two ends along the axial direction. When stacked originals are placed on the tray body, the first rod can be pushed against by the stacked originals and move between a first position and a second position as the number of originals decreases. The second rod rotates synchronously with the first rod through the connecting shaft, so that the second rod moves between a position that blocks and does not block the detection signal sent by the device. The sensor is configured to receive a feedback signal corresponding to the detection signal.

[0016] In one embodiment, the device body includes a paper feeding assembly, which includes a paper feeding component and a paper blocking component. The paper blocking component is configured to stop a document placed on the tray body. The paper blocking component is rotatably engaged in a guide rib of the housing. The paper feeding component is configured to feed at least one sheet of the document from the document on the tray body. The paper blocking component is rotatable under the push of the fed document, so that the document moves in the transport path. In another embodiment, the device body includes a glass stage, a first image reader, and a second image reader. The first image reader and the second image reader are respectively disposed on different sides of the glass stage. When the image reading device scans a document on both sides, the first image reader can read information from one side of the document, and the second image reader can read information from the other side of the document.

[0020] The above-mentioned solution of this utility model has the following beneficial effects:

[0021] In this embodiment, the connector connected to the tray body is supported by the support surface and can be rotatably connected to the device body through the mounting hole. This allows the tray body to remain relatively stationary with respect to the device body without external force, enabling the tray body to support the original document to be read. When the original document is stuck inside the device body, the tray body can be opened, providing sufficient operating space for the user to remove the stuck original document. This reduces the difficulty of removing the stuck original document and also reduces the possibility of the original document being torn. This is particularly useful for original documents with special or small dimensions, such as invoices.

[0022] Other beneficial effects of this invention will be described in detail in the following detailed description section. Attached Figure Description

For example, they can refer to a locking connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] This application provides an image reading device; please refer to [link / reference]. Figure 1 , Figure 1 The specific structure of the image reading device of this application is shown. For details, please refer to... Figure 2 and Figure 3 The image reading device includes an input tray 1, an output tray 3, and a device body 2. The input tray 1 includes a tray body 11 and a connector 12. The tray body 11 is configured to hold the original document to be read. The output tray 3 is configured to hold the original document that has already been read. The device body 2 is configured to read the original document and provide a transmission path for it, outputting the read original document to the output tray 3. Here, all components of the image reading device other than the input tray 1 and the output tray 3 are collectively referred to as the device body 2. For example, an original document to be read is placed in the tray body 11, the device body 2 receives the original document from the tray body 11, and reads the information in the original document. After reading is complete, the device body 2 can also output the scanned original document to the output tray 3.

[0037] The main body 2 of the equipment has a support surface 21 and a mounting hole 22 on one side along the first direction. For example, Figure 1 , Figure 2 and Figure 3 The direction shown by R1 is the first direction, and the support surface 21 and the mounting hole 22 are both located on one side of the equipment body 2 along the first direction.

[0038] Please see Figure 3The support surface 21 can be arranged perpendicularly to the side of the equipment body 2 along the first direction, and the mounting hole 22 can penetrate the side of the equipment body 2 along the first direction. The support surface 21 and the mounting hole 22 can also be arranged approximately along the second direction. Figure 3 The direction shown by R2 is the second direction, and the first and second directions are arranged intersecting. For example, mounting hole 22 can be arranged as follows: Figure 3 As shown, it is positioned approximately above the support surface 21 along the second direction.

[0039] The connector 12 is disposed on one side of the pallet body 11 along the first direction. For example, the connector 12 can be as follows: Figure 2 The connector 12 is located on opposite sides of the pallet body 11 along a first direction. In the arrangement direction of the pallet body 11 and the equipment body 2, the connector 12 is positioned on the side of the pallet body 11 closer to the equipment body 2, allowing the pallet body 11 to be connected to the equipment body 2 via the connector 12. A support surface 21 is configured to support the connector 12. For example, the support surface 21 can support the lower side of the connector 12 along a second direction. The connector 12 is also rotatably connected to the equipment body 2 via a mounting hole 22.

[0040] For example, please see Figure 2 The connector 12 has a convex shaft 123 on its upper side along the second direction. The convex shaft 123 can pass through the mounting hole 22, so that the connector 12 is rotatably connected to the device body 2. This also allows the connector 12 to rotate only about the axial direction of the mounting hole 22 and not translate relative to the device body 2. When the connector 12 is supported by the support surface 21 on its lower side along the second direction, the tray body 11 has a state of relative stillness with respect to the device body 2 and a state of rotation relative to the device body 2 about the axial direction of the mounting hole 22. For example, normally, the tray body 11 is used to hold the original document to be read, and it remains relatively still with respect to the device body 2 without external force. In case of an emergency, such as when the original document becomes stuck inside the device, preventing the device from reading the original document normally, an external force needs to be applied to the tray body 11 to allow it to rotate relative to the device body 2 about the axial direction of the mounting hole 22, providing operating space for the user to remove the original document from the device.

[0041] In this embodiment, the connector 12, which is connected to the tray body 11, is supported by the support surface 21 and can be rotatably connected to the device body 2 through the mounting hole 22. The tray body 11 can remain relatively stationary with respect to the device body 2 without external force, supporting the original document to be read. When the original document is stuck inside the device body 2, the tray body 11 can rotate relative to the device body 2, allowing the tray body 11 to open and providing operating space for the user to remove the stuck original document from the device body 2. This facilitates the user in removing the stuck original document from the device body 2 and reduces the difficulty of removing the original document stuck in the device body 2. The range of rotation of the tray body 11 relative to the device body 2 can be set according to actual needs. For example, for original documents with special or small dimensions, such as invoices, the rotation range can be increased to reduce the possibility of tearing special types of original documents stuck in the device body 2.

[0042] In one embodiment, please refer to Figure 3 and Figure 4 The support surface 21 includes an interconnected support sub-surface 211 and a clearance surface 212. The support sub-surface 211 is configured to support the connector 12. For example, the support sub-surface 211 is capable of supporting one side of the connector 12 along a second direction. The clearance surface 212 is inclined relative to the support sub-surface 211. For example, the pallet assembly can be inclined along... Figure 2 The rotation direction shown by R3 is relative to the main body 2 of the equipment, and the clearance surface 212 can be as follows: Figure 4 The tray body 11 is tilted to the lower left as shown, so that the main body 2 of the device has a clearance space 4 that can avoid the rotation of the connector 12, so that the tray body 11 can rotate at a certain angle relative to the main body 2 of the device, so that the user can easily remove the stuck original from the main body 2 of the device.

[0043] In one embodiment, please refer to Figure 2 The connector 12, near the support surface 21, includes an interconnected abutment surface 121 and a limiting corner 122. When the tray body 11 supports the original to be read, the abutment surface 121 abuts against the support sub-surface 211. When the paper feed tray 1 rotates relative to the device body 2, the limiting corner 122 abuts against the clearance surface 212 to limit the paper feed tray 1. For example, the paper feed tray 1 can rotate along... Figure 2 The rotation direction shown by R3 is relative to the main body 2 of the equipment. When the limiting corner 122 abuts against the clearance surface 212, the paper feed tray 1 can no longer rotate, so as to avoid excessive rotation of the paper feed tray 1 relative to the main body 2 of the equipment.

[0044] In one embodiment, please refer to Figure 2 and Figure 3The equipment body 2 has a support surface 21 and a mounting hole 22 on both sides of the first direction. The pallet body 11 is connected to the connecting piece 12 on both sides of the first direction, so that the pallet body 11 can be rotatably connected to the equipment body 2 on both sides of the first direction through the connecting piece 12, which is beneficial to improving the connection strength and stability between the pallet body 11 and the equipment body 2.

[0045] In one embodiment, please refer to Figure 2 , Figures 5-7 , Figure 2 and Figure 7 The assembly structure of the first tray 111 and the second tray 112 is shown from different perspectives. The tray body 11 includes the first tray 111 and the second tray 112. The first tray 111 is connected to the device body 2 via a connector 12, and the second tray 112 is slidably connected to the first tray 111. For example, the second tray 112 can slide relative to the first tray 111 along the original document transport path. On the one hand, this can increase the area of ​​the tray body 11, allowing the tray body 11 to better accommodate original documents with a larger area; on the other hand, when the tray body 11 is used to accommodate original documents with a smaller area, the second tray 112 can also be retracted into the first tray 111 to reduce the area of ​​the tray body 11.

[0046] For example, please refer to Figure 5 The first tray 111 has a sliding groove 1111 on the side near the second tray 112, and the second tray 112 is slidably connected to the first tray 111 within the sliding groove 1111.

[0047] In one embodiment, please refer to Figure 5 and Figure 6 The first tray 111 has a stop 1112 projecting toward the second tray 112, the stop 1112 being configured to limit the range of movement of the second tray 112 relative to the first tray 111. For example, the stop 1112 includes, Figure 5 The first stop 11121 and the second stop 11122 are configured to limit the distance the second tray 112 moves toward the first tray 111, so as to reduce the possibility that the second tray 112 moves too deep into the first tray 111 and is difficult to remove. The second stop 11122 is configured to limit the distance the second tray 112 moves toward the outside of the second tray 112, so as to reduce the possibility that the second tray 112 moves too far and comes out of the sliding groove 1111.

[0048] In one embodiment, please refer to Figure 5 and Figure 6The first tray 111 has a protrusion 1113 that protrudes toward the second tray 112, and the protrusion 1113 can abut against the second tray 112. For example, the second tray 112 has a groove 2424 on the side facing the first tray 111. When the second tray 112 slides relative to the first tray 111, the protrusion 1113 can be located in the groove 2424, so that the second tray 112 can slide relative to the first tray 111 along the extending direction of the groove 2424, so that the second tray 112 can slide relatively smoothly and stably relative to the first tray 111.

[0049] In one embodiment, please refer to Figure 3 and Figure 8 The main body of the device 2 includes a housing 23, which can open and close the main body. The inner wall of the housing 23 is provided with a guide for guiding the original. When the housing 23 is closed, it forms an original transmission path with the main body of the device 2.

[0050] The main body 2 of the device also includes a paper feeding assembly 24, which is disposed within the space enclosed by the outer casing 23 and the main body 2 after the casing 23 is closed. The paper feeding assembly 24 includes a paper feeder 241 and a paper stopper 243. The paper stopper 243 is configured to stop the originals placed on the tray body 11 and is rotatably engaged in the guide ribs of the outer casing 23. The paper feeder 241 is configured to feed at least one original from the originals on the tray body 11, and the paper stopper 243 can rotate under the push of the fed originals to move the originals in the transport path.

[0051] After the outer casing 23 is closed, a detection element 242 is also provided in the space enclosed by the device body 2. The detection element 242 is configured to sense whether there is a manuscript to be read in the tray body 11. The detection element 242 includes a first rod 2421, a second rod 2422, a connecting shaft 2423 and a sensor (not shown in the figure). The connecting shaft 2423 is rotatably engaged in the guide rib of the outer casing 23. The first rod 2421 and the second rod 2422 are respectively connected to the two ends along the axial direction. The first rod 2421, the second rod 2422 and the connecting shaft 2423 are an integral structure.

[0052] When stacked originals are placed on the tray body 11, the first rod 2421 can be pushed to a first position by the stacked originals. As the originals are gradually read (scanned) into the device, the number of originals placed on the tray body 11 gradually decreases, and the force exerted on the first rod 2421 by the originals stacked on the tray body 11 also gradually decreases. The first rod 2421 gradually moves away from the first position. When all originals have been read, there are no originals to be read on the tray body 11, and the first rod 2421 is no longer pushed by the originals and stays in the second position. Specifically, a groove 2424 can be provided in the device body 2. The end of the first rod 2421 away from the connecting shaft 2423 is inserted into the groove 2424. In the groove 2424, as the number of originals decreases, the first rod 2421 swings in the opposite direction to the direction of original movement. Along the direction of original movement, the first position is downstream of the second position. Here, the first position and the second position can be at opposite ends of the groove 2424 in the direction of original movement. The second rod 2422 rotates synchronously with the first rod 2421 through the connecting shaft 2423. The second rod 2422 moves between positions that block and do not block the sensor from transmitting signals. The sensor can transmit signals and receive feedback signals, so that the image reading device can determine whether the original is stacked on the tray body 11 based on the feedback signals.

[0053] Specifically, the sensor can be a photodetector to receive a feedback signal corresponding to the light signal sent by the device. For example, when there are stacked originals on the tray body 11, the second rod 2422 does not block the light signal. The device confirms that there are originals on the tray based on the received feedback signal. When there are no stacked originals on the tray body 11, the second rod 2422 rotates to the position that blocks the light signal. The device confirms that there are no originals on the tray based on the magnitude of the feedback signal received by the sensor.

[0054] For example, please refer to Figure 3 and Figure 8The paper stop 243 is generally Y-shaped and includes a bottom end 2431 and a top end 2432. The paper stop 243 is fixed in the guide ribs of the housing 23. Each paper stop 243 is fixed by at least two ribs with hook-shaped grooves. The paper stop 243 can rotate around the connection with the ribs. When the paper feeder 241 is not driven to feed, one arm of the paper stop 243 (e.g., the top end 2432) abuts against the paper feeder 241. The paper feeder 241 can restrict the rotation of the paper stop 243 to stop the original placed on the tray assembly. The paper feeder 241 is driven by a power source (such as a motor) via gears to rotate a drive shaft. The drive shaft rotates the paper feeder 241. During paper feed, the paper feeder 241 separates from the paper stopper 243. The feeder pushes aside the paper stopper 243 (the feeder exerts force on the bottom end 2431 of the paper stopper, causing it to rotate) and enters the main body 2 of the equipment. For example, the paper feeder 241 may include a drive wheel, a paper feed roller, and a separation pad. The drive wheel and the paper feed roller are connected by a gear set so that the drive wheel can drive the paper feed roller to feed the paper. When the paper feeder passes between the paper feed roller and the separation pad, the friction between the paper feed roller and the separation pad allows only one sheet of paper to pass through. When the user places a document on the tray assembly, the front end of the document pushes against the detector 242 so that the equipment can detect whether there is paper.

[0055] In one embodiment, the main body 2 of the device further includes a glass stage 6, a first image reader, and a second image reader. The glass stage 6 has a supporting surface, which can also support the original document to be read. The first image reader and the second image reader are located on different sides of the glass stage 6, such as the upper and lower sides of the glass stage 6. When the image reading device scans the original document carried by the paper tray 1 on both sides, the first image reader can read information from one side of the original document, and the second image reader can read information from the other side of the original document. When the image reading device reads the original document carried by the supporting surface of the glass stage 6, the image reader located on the lower side of the glass stage 6 reads the original document information.

[0056] For example, a first image reader is positioned below the glass stage 6, and a second image reader is positioned above the glass stage 6. The first image reader can be a CIS (Contact Image Sensor) or a CCD (Charge Coupled Device) camera, used to read the original document placed on the support surface of the glass stage 6. When the user scans using the glass stage 6, the original document is placed on the glass stage 6, and the first image reader moves to perform the original document scanning. When the user places the original document on the tray body 11, the second image reader performs the original document scanning. During this process, the original document moves along the transport path and is read when it passes the second image reader, which does not move. When the user selects to use double-sided scanning, the original document moves along the transport path, and neither the second nor the first image reader moves. The original document is in the transport path, and information from one side is read by the second and first image readers respectively.

[0057] In one embodiment, please refer to Figure 2 The image reading device may also include a regulating component 5, which is disposed on the tray body 11. The regulating component 5 is movable relative to the tray body 11 in a first direction, so that the original can be placed relatively neatly in the tray body 11 in the length or width direction.

[0058] The second aspect of this application provides a printer, including the image reading device and the printing body described in the above embodiments. The printing body is electrically connected to the image reading device and is configured to perform a printing task, which includes printing an image read by the image reading device.

[0059] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
