Description

Technical Field

[0001] The present invention relates to the field of scanning technology, and further to a scanning pen. Background Art

[0002] At present, all scanning pens on the market are integrated, with the scanning part and the display part in one unit. In order to allow the scanning pen to display more content, the display screen cannot be made too narrow, so the overall width of the scanning pen is relatively large. This will bring a problem. The wide pen body makes the scanning pen difficult to hold and cannot be used like a normal pen, resulting in a poor user experience.

[0003] In summary, a scanning pen is needed to solve the above problems. Summary of the invention

[0004] In view of the above technical problems, the purpose of the present invention is to provide a scanning pen that can provide a good holding experience and can be used detachably, so that users can scan according to usage scenarios and specific needs, and has excellent compatibility and operability.

[0005] In order to achieve the above-mentioned object, the present invention provides a scanning pen, comprising: a host part with a display screen and a scanning part, wherein the host part and the scanning part are provided with corresponding wireless transmission modules for data transmission;

[0006] The scanning part includes a first sub-part and a second sub-part, the second sub-part is provided with a first camera for scanning, the first sub-part and the second sub-part are slidably connected, so that the scanning part has at least a stretched state and a contracted state.

[0007] At least a portion of the second sub-section is received in the first sub-section in the contracted state;

[0008] The host part and the first sub-part are detachably connected, so that the host part and the scanning part can be used separately or together.

[0009] It should be noted that the scanning pen forms a three-section scanning pen structure by setting up a main unit, a first subunit, and a second subunit, which can greatly increase the length of the grippable part of the scanning pen, making the scanning pen more slender and providing a better feel for users when holding the scanning pen. In addition, the main unit and the scanning unit are separated, so that it can be used in more usage scenarios.

[0010] In some embodiments, the host part and the second sub-part are both provided with power supply modules for independent power supply; the host part and the first sub-part are both provided with corresponding magnetic attraction structures for fixing the first sub-part relative to the host part.

[0011] It is understandable that since the main unit and the scanning unit are separated, the magnetic structure here can effectively fix the two relatively, and it is very easy for users to use, and the fixing effect is not easily affected by the loss of parts.

[0012] In some embodiments, the magnetic attraction structure includes a first magnet matrix disposed on the main body portion, and a second magnet matrix disposed on the first sub-portion, the magnets in the first magnet matrix and the magnets in the second magnet matrix are attracted to each other in a one-to-one correspondence, and the first magnet matrix and the second magnet matrix each include at least two magnets.

[0013] When the host part and the scanning part are used together, a preset offset distance is provided between the matching magnets in the length direction of the host part, so that the host part and the scanning part are pressed against each other under the attraction of the magnets.

[0014] It is worth mentioning that the staggered arrangement between the matching magnets can generate an attractive force between the host part and the scanning part through the magnets, thereby driving the two to be close together and tightly attached, thereby ensuring the reliability of the fixation.

[0015] In some embodiments, the host part is provided with a sliding groove, and the sliding groove is used to match the sliding state of the scanning part; the first magnet matrix and the second magnet matrix each include three magnets, and the three magnets are sequentially arranged on the parking path of the first sub-part relative to the host part.

[0016] Moreover, in the first magnet matrix and the second magnet matrix, the magnetic poles of the magnets close to the bottom of the sliding groove are different from the magnetic poles of the other two magnets, so that the three magnets are distinguished as one positioning end and two auxiliary positioning ends, so that when the first branch moves from the starting end of the sliding groove to the bottom of the sliding groove, the positioning end of the first branch passes through the two auxiliary positioning ends of the main unit in sequence, and the repulsive action of the magnets causes the first branch to move to a preset fixed position.

[0017] It should be noted that the magnetic fixation between the main unit and the first division is achieved through the repulsion and attraction between the three-section magnets, and the magnetic pole setting of the three-section magnets is also very clever. When the user pushes the first division to fix it, the first two sections of the magnets on the main unit produce a repulsive force relative to the first section of the magnet on the first division, which makes the first division move deeper until the first section of the magnet on the first division is attracted to the last section of the magnet on the main unit and is fixed. This effectively avoids the situation where the first division is positioned at other positions, such as the middle of the sliding groove, due to unreasonable magnetic pole setting, which would make it more difficult for the user to continue pushing the first division.

[0018] In some embodiments, the preset misalignment distance ranges from 0 to 5 mm.

[0019] In some embodiments, the main unit and the first subunit are both provided with corresponding first clamping structures for fixing the first subunit relative to the main unit.

[0020] The first clamping structure can prevent the scanning part from becoming loose relative to the main body part when the scanning part and the main body part are used together, thereby preventing the scanning part from falling and causing property loss to the user.

[0021] In some embodiments, the first snap-fit ​​structure includes at least one snap-fit ​​component disposed on the host portion, and at least one first snap-fit ​​groove disposed on the periphery of the first sub-portion, the first snap-fit ​​groove being matched with the snap-fit ​​component so that when the first sub-portion is used in combination with the host portion, the snap-fit ​​component is engaged in the first snap-fit ​​groove to limit the displacement of the first sub-portion.

[0022] In some embodiments, corresponding second clamping structures are provided on both the first section and the second section, so that when the second section slides to the extreme position, it is fixed to the end of the first section through the second clamping structure to prevent the second section from falling off.

[0023] Here, the second clip structure is used for clipping and fixing between the first section and the second section, so that when the second section is unfolded for use, the first section can be limited and will not slide, and the user's hand is prevented from being hit by the sliding first section when holding the scanning pen, causing injury to the user's hand.

[0024] In some embodiments, the second clamping structure includes at least one second clamping slot arranged on the inner periphery of the first section, and at least one spring clip buckle arranged on the end of one side of the second section close to the first section, the spring clip buckle corresponds to the second clamping slot, wherein the protruding end of the spring clip buckle can be engaged in the second clamping slot to fix the second section relative to the first section.

[0025] In some embodiments, at least a portion of the second section is a transparent member, so that the first camera can scan through the transparent member; and the first camera is disposed in the second section via an angle adjustment mechanism to control the scanning range.

[0026] It should be noted that the transparent part can be used to block external moisture, dust and other substances, thereby protecting the camera and internal parts. The direction of the camera can be adjusted through the angle adjustment mechanism to increase or decrease the scanning amount. It also avoids the user turning his wrist or arm to adjust the direction of the camera and maintaining the posture during the scanning process, which makes the hands very tired.

[0027] In some embodiments, the angle adjustment mechanism includes a knob, and the knob is connected to a side wall of the first camera through a rotating member, so that the first camera is driven to rotate synchronously with the rotating member to adjust the direction of the first camera.

[0028] In some embodiments, a physical pen core is disposed in the second subsection for writing;

[0029] The second section is provided with a through hole corresponding to the physical pen core at an end portion of one side away from the main body, and a sliding button is provided on the second section, and the sliding button is connected to the physical pen core, so that when the sliding button is turned, the physical pen core is synchronously extended out of the through hole, allowing the scanning pen to enter the writing mode.

[0030] In some embodiments, a circuit board is disposed on the inner side wall of the first sub-part for transmitting electrical signals; a plurality of connection contacts are disposed on the circuit board, and connection probes are disposed on the host part and the second sub-part to match the corresponding connection contacts, which are suitable for transmitting data or charging.

[0031] At least two of the plurality of connection contacts are arranged at two ends of the circuit board on one side close to the second sub-portion to match the stretched state or the contracted state of the scanning portion.

[0032] Among them, data transmission or charging can be carried out between the host part and the scanning part through connecting contacts and connecting probes, and the position of the connecting contacts is also very clever. When the second part is pulled open or retracted, the connecting probes on the second part can cooperate with the corresponding connecting contacts, making it more convenient for users to use and less restricted.

[0033] In some embodiments, the host unit includes a rotating bracket, which is arranged on a side of the host unit away from the display screen via a rotating shaft, and the axial direction of the rotating shaft is consistent with the length direction of the host unit, for supporting the host unit.

[0034] It is worth mentioning that when the user is viewing the contents on the display screen, the entire scanning pen or the main unit can be supported by rotating the bracket, so that the user does not need to hold the scanning pen all the time. When charging the scanning pen, the scanning pen can also be clamped by rotating the bracket to avoid scratches on the outer shell of the scanning pen.

[0035] In some embodiments, the host unit includes a second camera, which is located on a side of the host unit away from the display screen and is suitable for taking pictures or scanning;

[0036] And a speaker module is arranged adjacent to the second camera, and the speaker module is suitable for emitting a low-battery reminder sound or a charging reminder sound.

[0037] Compared with the prior art, the scanning pen provided by the present invention has the following beneficial effects:

[0038] 1. The scanning pen provided by the present invention has a detachable design for the scanning part and the host part. When using the scanning pen, the user can change the usage mode of the scanning pen according to specific needs, so that the host part and the scanning part can be used independently or in combination.

[0039] 2. The scanning pen provided by the present invention has a retractable scanning part, which can make the user's holding feel closer to a normal pen, making the holding feel very comfortable and the hand does not need to be opened at an excessive angle and range.

[0040] 3. The scanning pen provided by the present invention can adopt a variety of fixing methods when fixing the scanning part and the host part, such as magnetic fixation or snap fixation, to avoid the scanning part falling off from the host part when the two are used in combination and causing damage to the equipment.

[0041] 4. The scanning pen provided by the present invention has a very clever arrangement of magnets used for magnetic fixation, which can effectively prevent the scanning part from being accidentally adsorbed at the wrong position during the process of being fixed to the host part, and the staggered distribution of the magnets allows the scanning part and the host part to be close to each other during magnetic fixation, so that the positioning effect is very good and the body is not easy to slip.

[0042] 5. The scanning pen provided by the present invention is also provided with a physical refill in the scanning part, so that the scanning pen has scanning and writing functions, which makes it more convenient for users to scan and write, and most of their needs can be met by just carrying the scanning pen.

[0043] 6. The scanning pen provided by the present invention can adjust the angle of the camera to achieve the change of the scanning range. It is highly operable and can be adjusted according to different scanning scenes to increase or decrease the scanned content accordingly. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0064] In one embodiment, the reference specification Figure 1A scanning pen provided by the present invention is described. The scanning pen provided by the present invention can provide a good holding experience and can be used detachably, so that the user can scan according to the usage scenario and specific needs, and has excellent compatibility and operability.

[0065] Reference Manual Attached Figures 1 to 3 The present invention provides a scanning pen, which includes a host part 1 having a display screen 10 and a scanning part 2. The host part 1 and the scanning part 2 are provided with corresponding wireless transmission modules for data transmission.

[0066] The scanning part 2 includes a first section 21 and a second section 22. The second section 22 is provided with a first camera 220 for scanning. The first section 21 and the second section 22 are slidably connected so that the scanning part 2 has at least a stretched state and a contracted state. At least a portion of the second section 22 is accommodated in the first section 21 when in the contracted state. The main unit 1 and the first section 21 are detachably connected so that the main unit 1 and the scanning part 2 can be used separately or together.

[0067] It should be noted that the scanning pen forms a three-section scanning pen structure by setting up the main unit 1, the first subunit 21, and the second subunit 22, which can greatly increase the length of the grippable part of the scanning pen, making the scanning pen more slender and providing a better feel for the user when holding the scanning pen. In addition, the main unit 1 and the scanning unit 2 are separately set, so that it can be used in more usage scenarios.

[0068] Optionally, the corners of the main unit 1 are all rounded, which is more beautiful and less likely to hurt the hands, further improving the user's holding experience.

[0069] Specifically, during use, if the user uses the scanning pen in combination, the user can directly pull the second section 22 out of the first section 21 to perform scanning. According to the user's habits and hand size, the user can hold the main unit 1 or the second section 22 to obtain different experiences, which is more user-friendly than a scanning pen with only a single holding part. Moreover, the side walls of the main unit 1 or the second section 22 can be set to frosted material or other anti-slip material to make the scanning pen feel better.

[0070] In one embodiment, power supply modules are provided in the host part 1 and the second part 22 for independent power supply; corresponding magnetic structures are provided on the host part 1 and the first part 21 for fixing the first part 21 relative to the host part 1.

[0071] It is understandable that, since the main unit 1 and the scanning unit 2 are separately arranged, the magnetic structure here can effectively fix the two relatively, and it is very easy for users to use, and the fixing effect is not easily affected by the loss of parts.

[0072] Moreover, the main unit 1 and the second subunit 22 are powered independently, so that the power of the scanning pen in this embodiment can be supported when the main unit 1 and the scanning unit 2 are used separately. Figure 5 In the figure, the two power supply modules are respectively marked as a first power supply module 51 and a second power supply module 52.

[0073] In another embodiment, based on the above embodiment, the Figure 6 and Figure 7 A circuit board 3 is arranged on the inner wall of the first section 21 for transmitting electrical signals; a plurality of connection contacts 31 are arranged on the circuit board 3, and connection probes 32 are arranged on both the host section 1 and the second section 22 to match the corresponding connection contacts 31, which are suitable for transmitting data or charging.

[0074] At least two of the plurality of connecting contacts 31 are disposed at two ends of the circuit board 3 close to the second section 22 to match the extended state or the contracted state of the scanning section 2 .

[0075] Among them, data transmission or charging can be carried out between the host part 1 and the scanning part 2 through the connecting contacts 31 and the connecting probes 32. It is easy to imagine that the host part 1 and the scanning part 2 are naturally also provided with corresponding holes at the position where the connecting contacts 31 and the connecting probes 32 are in contact. Similarly, the number of holes also corresponds to the arrangement number of the two.

[0076] Moreover, the connection contacts 31 are arranged at positions very cleverly. When the second section 22 is pulled open or retracted, the connection probes 32 on the second section 22 can cooperate with the corresponding connection contacts 31, making it more convenient for users to use with fewer restrictions.

[0077] Corresponding to this embodiment, a charging port is provided on the host part 1, and the charging port is electrically connected to the power supply module, so that the user can charge the host part 1 through the charging port, and the scanning part 2 can also be synchronously charged through the coordinated use of the connection contacts 31 and the connection probes 32 in the above embodiment.

[0078] In one embodiment, the reference specification Fig.11 and Fig.12 The magnetic attraction structure includes a first magnet matrix arranged on the main body part 1, and a second magnet matrix arranged on the first sub-part 21. The magnets 400 in the first magnet matrix are attracted to the magnets 400 in the second magnet matrix in a one-to-one correspondence, and the first magnet matrix and the second magnet matrix respectively include at least two magnets 400.

[0079] Moreover, when the host part 1 and the scanning part 2 are used together, a preset offset distance d is set between the matching magnets 400 in the length direction of the host part 1, so that the host part 1 and the scanning part 2 are pressed against each other under the attraction of the magnets 400.

[0080] It should be noted that in some other embodiments, only one magnet 400 may be provided on the main unit 1 and the first subunit 21 respectively, and the two magnets 400 may attract each other and achieve magnetic fixation. However, this magnetic fixation method is not very reliable. The two attracting magnets 400 may become loose due to bumps or shaking, and the scanning unit 2 may fall off, which may cause inconvenience to the user. The provision of at least two magnets 400 in this embodiment also provides a good guarantee for the fixation of the scanning unit 2.

[0081] It is worth mentioning that the misaligned arrangement between the matching magnets can generate an attractive force between the host part 1 and the scanning part 2 through the magnets, thereby driving the two to be close and close to each other, thereby ensuring the reliability of the fixation.

[0082] Reference Manual Attached Fig.12 , wherein the arrangement of the S pole and the N pole of the magnet 400 is only one implementation in this embodiment. In this embodiment, the position of the S pole is replaced by the N pole, and the position of the N pole is replaced by the S pole, which can also achieve the above-mentioned staggered setting and clamping effect. In other embodiments, as long as the effects and technical concepts are the same, they should be included in the protection scope of the present invention.

[0083] Optionally, the preset offset distance d is in the range of 0-5 mm to ensure that the magnets 400 will not affect the attraction due to excessive offset distance, resulting in the scanning unit 2 being unable to be well magnetically fixed on the host unit 1.

[0084] In one embodiment, based on the above embodiment, refer to the attached specification Figure 4 The host part 1 is provided with a sliding groove 150, and the sliding groove 150 is used to match the sliding state of the scanning part 2; the first magnet matrix and the second magnet matrix each include three magnets 400, and the three magnets 400 are sequentially arranged on the parking path of the first sub-part 21 relative to the host part 1,

[0085] Moreover, in the first magnet matrix and the second magnet matrix, the magnetic poles of the magnet 400 close to the bottom of the sliding groove 150 are different from the magnetic poles of the remaining two magnets 400, so that the three magnets 400 are distinguished as one positioning end and two auxiliary positioning ends, so that when the first section 21 moves from the starting end of the sliding groove 150 to the bottom of the sliding groove 150, the positioning end of the first section 21 passes through the two auxiliary positioning ends of the main unit 1 in sequence, and the first section 21 is prompted to move to a preset fixed position under the repulsive effect of the magnets.

[0086] It should be noted that the magnetic fixation between the main unit 1 and the first subunit 21 is achieved by the mutual repulsion and attraction between the three-segment magnets, so that the first subunit 21 will not be positioned to the wrong position, and the magnetic pole arrangement of the three-segment magnet is also very clever, which can be referred to in the appendix of the manual. Fig.12 Here, the three sections of magnets on the main unit 1 and the first subunit 21 are distinguished from left to right as magnet No. 1, magnet No. 2, and magnet No. 3. The magnetic poles of magnet No. 1 and magnet No. 2 of the main unit 1 are the same, but the magnetic poles of magnet No. 3 are different from those of magnets No. 1 and No. 2. The magnets on the first subunit 21 are also arranged in this way, which will not be repeated here. When the user pushes the first subunit 21 to fix it, magnets No. 1 and No. 2 of the main unit 1 both generate repulsive force relative to magnet No. 1 of the first subunit 21, so that the first subunit 21 is pushed deeper until magnet No. 1 of the first subunit 21 is attracted to magnet No. 3 of the main unit 1 to fix it. This effectively avoids the situation where the first subunit 21 is positioned at other positions, such as the middle of the sliding groove 150, due to unreasonable magnetic pole arrangement. In this way, the user will have more trouble when continuing to push the first subunit 21.

[0087] According to the magnet arrangement rules in the above embodiments, it is not difficult to obtain that in other embodiments, the number of rows and columns of magnets 400 in the first magnet matrix and the second magnet matrix can be increased or decreased according to specific circumstances. The number of rows and columns respectively corresponds to the length direction and width direction of the scanning pen, such as three rows and three columns, or four rows and two columns, etc., to adjust the strength of the connection.

[0088] In one embodiment, the main unit 1 and the first sub-unit 21 are both provided with corresponding first clamping structures for fixing the first sub-unit 21 relative to the main unit 1 .

[0089] Among them, the first clip-on structure can prevent the scanning part 2 from loosening relative to the main body part 1 when the scanning part 2 and the main body part 1 are used together, thereby causing the scanning part 2 to fall and cause property loss to the user. At the same time, this first clip-on structure can be used in combination with the magnetic attraction structure in the above embodiment to achieve a better fixing effect, and can also be used independently.

[0090] Based on the above embodiments, please refer to the attached manual. Figure 4 and Figure 8 The first snap-fit ​​structure includes at least one snap-fit ​​component 12 arranged on the host part 1, and at least one first snap-fit ​​groove arranged on the outer periphery of the first section 21. The first snap-fit ​​groove is matched with the snap-fit ​​component 12, so that when the first section 21 is used together with the host part 1, the snap-fit ​​component 12 is engaged in the first snap-fit ​​groove to limit the displacement of the first section 21.

[0091] The fastener 12 may be made of plastic or steel sheet material, and the cross-section of the protrusion on the fastener 12 may be a semi-ring or an isosceles trapezoid. In other embodiments, the protrusion of the fastener 12 has an inclined surface extending along the moving direction of the scanning unit 2, which can guide the fixing or disassembly of the scanning unit 2.

[0092] Furthermore, if conditions permit, the latching member 12 may also be disposed on the first sub-portion 21 , and the first latching slot may be correspondingly disposed on the host portion 1 , so that a fixing effect may also be achieved.

[0093] In one embodiment, the reference specification Fig. 9 The first section 21 and the second section 22 are both provided with corresponding second clamping structures, which are used to fix the second section 22 to the top of the first section 21 through the second clamping structure when the second section 22 slides to the extreme position, so as to prevent the second section 22 from falling off.

[0094] Here, the second clip structure is used for clipping and fixing between the first section 21 and the second section 22, so that when the second section 22 is unfolded for use, the first section 21 can be limited and will not slide, and the user's hand is prevented from being hit by the slipping first section 21 when holding the scanning pen, causing injury to the user's hand.

[0095] In another embodiment, based on the above embodiment, the Fig.10 The second clamping structure includes at least one second clamping groove arranged on the inner periphery of the first division 21, and at least one spring buckle 23 arranged on the end of one side of the second division 22 close to the first division 21, the spring buckle 23 corresponds to the second clamping groove, wherein the protruding end of the spring buckle 23 can be engaged in the second clamping groove so that the second division 22 is fixed relative to the first division 21.

[0096] It should be noted that the spring clip buckle 23 plays a similar role to the snap-fit ​​part 12 in the above embodiment, so the same part can be directly used in actual products, avoiding the complexity of the parts types and improving assembly efficiency.

[0097] Optional, as specified in the instruction manual Figure 8 A limiting belt 250 extends from the end of the first section 21 near the second section 22, and the limiting belt 250 forms a limiting area surrounding the outer periphery of the second section 22. The spring clip buckle 23 will abut against the limiting area, so that the second section 22 will not fall off due to excessive pulling force by the user.

[0098] In another embodiment, guide structures are respectively provided on the inner periphery of the first division 21 and the outer periphery of the second division 22. The guide structure may be a combination of a guide groove, a guide bar, or a combination of a guide groove and a guide rail, which will not be described in detail here. The guide structure can avoid offset between the first division 21 and the second division 22, and can also reduce the friction force generated when the second division 22 slides, thereby avoiding friction or scratches and increasing the life of the equipment.

[0099] In one embodiment, the reference specification Figure 5 and Figure 8 At least a portion of the second section 22 is a transparent member 221, so that the first camera 220 can scan through the transparent member 221; and the first camera 220 is disposed in the second section 22 through an angle adjustment mechanism to control the scanning range.

[0100] It should be noted that the transparent part 221 can be used to block external moisture, dust and other substances, thereby protecting the camera and internal parts. In specific use, it can be configured with a plastic material to prevent breakage or cracks after falling, thereby affecting the quality of scanning.

[0101] Moreover, the direction of the camera can be adjusted through the angle adjustment mechanism to increase or decrease the scanning amount, which also avoids the user turning his wrist or arm to adjust the direction of the camera and maintaining the posture during the scanning process, which makes the hand very tired.

[0102] In one embodiment, the angle adjustment mechanism includes a knob 222 , which is connected to a side wall of the first camera 220 via a rotating member, so that the first camera 220 is driven to rotate synchronously with the rotating member to adjust the direction of the first camera 220 .

[0103] In this embodiment, the combination of the knob 222 and the rotating member is convenient to use, and the scanning range can be adjusted directly through this mechanical structure during the scanning process. In other embodiments, the rotating member can also be connected to the main board, so that the user can directly control the direction of the first camera 220 through the control end, and can have more precise control over the rotation direction or rotation speed.

[0104] In other embodiments, a plurality of strip-shaped grooves are provided on the surface of the knob 222. Firstly, the strip-shaped grooves can make it more convenient for the user to rotate the knob 222. Some users can directly insert their nails into the grooves and rotate them. Users who are not convenient to rotate the knob 222 with their nails have a greater friction force relative to the knob 222, which is also more convenient for rotation. In addition, it should be noted that the height of the protruding part of the knob 222 relative to the surface of the second division 22 is smaller than the gap between the second division 22 and the first division 21, so it will not affect the relative sliding between the second division 22 and the first division 21.

[0105] In one embodiment, the reference specification Fig. 9 A physical pen core 200 is disposed in the second section 22 for writing.

[0106] Among them, a through hole corresponding to the physical pen core 200 is set at the end of the second section 22 away from the main unit 1, and a sliding button 20 is set on the second section 22. The sliding button 20 is connected to the physical pen core 200. When the sliding button 20 is turned, the physical pen core 200 is synchronously extended out of the through hole, so that the scanning pen enters the writing mode.

[0107] It is worth mentioning that the physical refill 200 provided in this embodiment can provide the user with a different scanning pen experience and enable the scanning pen to be used in more usage scenarios; and the extension or storage of the physical refill 200 can be controlled by sliding the button 20, thereby avoiding the situation where the pen tip is always exposed.

[0108] In one embodiment, the reference specification Figure 4 The host part 1 includes a rotating bracket 6, which is arranged on the side of the host part 1 away from the display screen 10 through a rotating shaft. The axial direction of the rotating shaft is consistent with the length direction of the host part 1, and is used to support the host part 1.

[0109] It is worth mentioning that when the user is viewing the contents of the display screen 10, the scanning pen as a whole or the host unit 1 can be supported by rotating the bracket 6, so that the user does not need to hold the scanning pen all the time. When charging the scanning pen, the scanning pen can also be clamped by rotating the bracket 6 to avoid scratches on the outer shell of the scanning pen.

[0110] In other embodiments, a groove is provided at the bottom of the sliding groove 150, and the size of the groove matches the rotating bracket 6, so that the rotating bracket 6 is set in the groove, and when the rotating bracket 6 is received in the groove, the rotating bracket 6 is flush with the surface of one side of the main unit 1, so that the integrity is very strong.

[0111] In one embodiment, the instructions are attached. Figure 1 and Figure 5The host part 1 includes a second camera 100, which is located on the side of the host part 1 away from the display screen 10 and is suitable for taking pictures or scanning; and a speaker module 11 arranged adjacent to the second camera 100, and the speaker module 11 is suitable for emitting a low-battery reminder sound or a charging reminder sound.

[0112] It can be understood that the second camera 100 can give the scanning pen more operating space. The user can realize synchronous scanning of two devices through the second camera 100 set on the host part 1 and the first camera 220 set on the scanning part 2. The scanned documents and contents can be transmitted to the host part 1 or the user's smart device through Bluetooth or network connection, which improves the scanning efficiency; or take pictures through the second camera 100 and upload the taken pictures to the cloud, etc.

[0113] In addition, the host part 1 is also provided with a sound hole 110 corresponding to the speaker module 11 , so that the sound can be transmitted from the sound hole 110 , making the sound effects such as the battery prompt sound very clear.

[0114] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
