DETAILED DESCRIPTION

[0038] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0039] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected" and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0041] A scanning pen is a handheld scanning device, which is widely used by students, teachers, business staff and other groups. Scanning pens can be divided into dictionary pens, translation pens, scanning pens and the like according to different application scenarios. Existing scanning pens are generally in the shape of long strips. When a user uses a scanning pen, the user's hand grasps or holds the pen body of the scanning pen, and the bottom of the scanning pen is placed on a scanning surface such as a book or document paper, and then the scanning pen is moved on the paper. During the movement, the acquisition module inside the scanning pen collects text, images and other information on the scanning surface, and the scanning pen performs subsequent information display, information storage, translation and other processing based on the collected information. Among them, when using the scanning pen, the bottom of the scanning pen needs to be kept against the scanning surface as much as possible to more clearly collect the information on the scanning surface and ensure the scanning effect.

[0042] In the related art, the scanning pen is generally flat in shape, but cannot adapt to the different holding and scanning habits of different users. The user may not be able to hold the scanning pen in a more comfortable posture for scanning.

[0043] In order to solve these problems, the present invention provides a scanning pen, the pen body 10 of the scanning pen can be tilted relative to the pen head 20, can adapt to more pen-holding postures, and make the pen holding more comfortable; and the pen body 10 can be tilted in both directions relative to the pen head 20, which can achieve the function of being suitable for both left and right hands, thereby improving the user experience.

[0044] Please refer to Figures 1 to 14 The rotatable scanning pen includes a pen body 10, a pen head 20, a rotating mechanism 30 and a collection module 40.

[0045] The pen body 10 is the main body of the scanning pen, and a circuit board is arranged inside the pen body 10. The pen tip 20 is used to rest against the scanning surface and to slide on the scanning surface. The acquisition module 40 is used to acquire information such as text and images. The acquisition module 40 may be, but is not limited to, a camera module. The acquisition module 40 is electrically connected to the circuit board. The acquisition module 40 is arranged on the pen tip 20 or on the rotating mechanism 30. The pen tip 20 is connected to the pen body 10 through the rotating mechanism 30, so that the pen tip 20 can rotate relative to the pen body 10 around a rotation axis perpendicular to the front of the pen body 10. In this embodiment, the pen tip 20 is relatively fixedly connected to the rotating mechanism 30, and the rotating mechanism 30 is rotationally connected to the pen body 10.

[0046] Based on the setting of the rotating mechanism 30, the pen head 20 and the pen body 10 can rotate relatively to the left or right, so that the pen body 10 can be adjusted between the right-leaning state and the left-leaning state. Figures 3 to 5 As shown in FIG. 1 , when the pen body 10 is in the right-leaning state, the pen body 10 is tilted toward the right side of the scanning pen relative to the pen head 20. Figures 6 to 8 As shown in FIG. 1 , when the pen body 10 is in a left-leaning state, the pen body 10 is tilted toward the left side of the scanning pen relative to the pen head 20. Figure 1 to Figure 2As shown, the pen body 10 also has a straight state, and when the pen body 10 is in the straight state, the pen body 10 is not tilted. When the user uses the scanning pen, the pen body 10 can be adjusted to the left tilt state or the right tilt state according to whether the pen is held in the left hand or the right hand, so that when the pen head 20 is against the scanning plane 93, the pen body 10 is tilted in the direction close to the base of the user's hand (i.e., close to the body), so that the holding posture is more comfortable and it is easier to perform scanning actions.

[0047] The pen body 10 includes a display screen 12, which is located on the front of the scanning pen. The display screen 12 is used to display interactive pages and also to display characters or pictures after scanning. In the present application, the pen body 10 includes a first body 11, and the display screen 12 is located on the front of the first body 11. Figures 1 to 8 In the embodiment, a side button 13 is also provided on the right side of the first body 11 for power on / off control or other control. In the present application, the left side of the scanning pen refers to: when the front of the scanning pen is facing the user, the user's left hand side is the left side of the scanning pen; the right side of the scanning pen refers to: when the front of the scanning pen is facing the user, the user's right hand side is the right side of the scanning pen. In order to conveniently distinguish the left and right sides of the scanning pen, some of the drawings illustrate the first left side portion 102 of the pen body 10 and the first right side portion 101 of the pen body 10, the side where the first left side portion 102 is located is the left side of the scanning pen, and the side where the first right side portion 101 is located is the right side of the scanning pen.

[0048] The pen body 10 has a first center line 91, and the extension direction of the first center line 91 is consistent with the length direction of the pen body 10. The acquisition module 40 has a second center line 92, and the acquisition module 40 has a acquisition surface. The second center line 92 is a vertical line passing through the center of the acquisition surface. When the acquisition module 40 acquires information on a scanning surface such as a book, the acquisition surface faces the scanning surface; wherein, when the acquisition module 40 is a camera module, the acquisition surface is the light incident surface of the lens of the camera module. When the pen body 10 rotates to the left or right side of the scanning pen relative to the pen head 20, the first center line 91 swings to the left or right, and the relative angle between the first center line 91 and the second center line 92 changes. Refer to Figures 3 to 8 When the pen body 10 is in a left-leaning state or a right-leaning state, the first center line 91 and the second center line 92 are both angled, and the angle between the two center lines is A. Figure 1 , Figure 2 When the pen body 10 is in a straight state, the first center line 91 and the second center line 92 are parallel to each other.

[0049] In the related art, the scanning pen is generally a flat plate structure with a certain thickness and slightly smaller than the width of the mobile phone, that is, a straight structure. However, since the existing scanning pen is a straight structure, the user's holding posture of the scanning pen is limited, and it cannot meet the scanning pen usage needs of users with different hand sizes and different pen holding postures.

[0050] In the first aspect of the scanning pen of the present invention, the pen body 10 is inclined relative to the pen head 20, so that Figure 5 , Figure 8 When the user holds the scanning pen and places the pen tip 20 against a scanning surface such as paper, the pen body 10 can be tilted relative to the scanning surface, and can adapt to different hand shapes and pen holding gestures, making scanning more comfortable and the human-machine interface more comfortable.

[0051] Secondly, the pen body 10 can be tilted to the left or right to adapt to left-handed or right-handed holding methods, which has a wider range of applications.

[0052] Thirdly, the pen body 10 can also be adjusted to a non-tilted state, that is, a straight state, to adapt to different hand shapes and pen holding requirements.

[0053] Fourthly, when the pen body 10 is in a tilted state, the display effect of the display screen 12 is better, and the user can easily read and understand the information displayed on the display screen 12. Figures 3 to 5 Taking the right hand as the dominant hand as an example, when holding the scanning pen for scanning, the pen body 10 is in a right-leaning state. At this time, the display screen 12 is tilted toward the direction close to the base of the thumb. The text or image and other information on the display screen 12 can be better displayed to the user's field of vision. The information on the display screen 12 seen by the user's eyes is distorted and the deflection angle is smaller. It is easier for the user to read and understand the text and other information on the display screen 12, and the interactive experience is better. For a scanning pen with a translation function, after the user scans a word, the display screen 12 can directly display the translation of the word. The user does not need to pick up the scanning pen from the scanning surface, which is also convenient for reading and understanding the translated words on the scanning pen, and the user experience is better.

[0054] Fifthly, by configuring the rotating mechanism 30, while satisfying the relative rotation of the pen body 10 and the pen tip 20, the coordination between the pen tip 20 and the pen body 10 and the pen tip 20 is more beautiful. When viewed from the front of the scanning pen, the coordination between the pen body 10 and the pen tip 20 is more integrated, and the user's visual experience and usage experience are better. Specifically, compared with directly rotationally connecting the nib 20 to the pen body 10, for example, disposing a rotating shaft between the nib 20 and the pen body 10, and the nib 20 is rotationally connected to the pen body 10 through the rotating shaft. The present application adopts a rotation installation method in which a rotating mechanism 30 is additionally provided between the nib 20 and the pen body 10, and the nib 20 is directly fixed to the rotating mechanism 30, and the rotating mechanism 30 is rotationally connected to the pen body 10. The fixed connection between the nib 20 and other components is easier to achieve than the rotational connection between the nib 20 and other components. The nib 20 is fixedly connected to the rotating mechanism 30, and there is no need to set a structure for rotational cooperation on the nib 20. The material selection and the structural selection of the nib 20 can be more flexible, which is conducive to improving the overall cooperation between the pen body 10 and the nib 20.

[0055] For example, when using the straight scanning pen in the related art, some users press their thumbs on the front of the scanning pen, press their index finger or the index finger and middle finger against the back of the scanning pen, then press the pen tip 20 of the scanning pen against the desktop, and then move the scanning pen horizontally to perform a scanning action. However, since the existing scanning pen has a straight structure, users can generally only press the first knuckles of the index finger and the middle finger against the back of the scanning pen for scanning. For some users, the scanning pen has a certain weight, and the user only uses the first knuckle to support the back of the scanning pen, which is not very comfortable; another part of users press the first knuckles of the thumb and index finger on the left and right sides of the scanning pen, and support the first knuckle of the middle finger on the back of the scanning pen. For some users, if the scanning pen is to be able to sweep left and right at this time, the flexibility of the user's wrist will be limited, and the wrist will feel a little uncomfortable.

[0056] When using the scanning pen of the present invention whose pen body 10 can be rotated to a tilted state, the user can adjust the pen body 10 to the right or left tilted state according to whether the dominant hand is the right hand or the left hand, while ensuring that the pen head 20 is against the scanning surface. When the user holds the scanning pen for horizontal scanning, the pen body 10 tilts toward the direction close to the base of the thumb of the user's right hand, and the user can support the scanning pen with the third knuckle of the index finger and the base of the thumb, which is more labor-saving and comfortable. When the pen body 10 tilts toward the base of the thumb, the restriction of the side of the pen body 10 on the index finger is reduced, the index finger can be adjusted more flexibly, the user's wrist can also be more flexible, and the left and right scanning action is more comfortable. The user can use but is not limited to using Figure 5 , Figure 8 The holding method in which the scanning pen is held for scanning is similar to the holding method of holding an ordinary signing pen for signing, and the user is more comfortable holding the scanning.

[0057] The pen body 10 of the scanning pen can be tilted and rotated within an angle range of plus or minus 30 degrees. The pen body 10 has a left-tilt limit position, a center position, and a right-tilt limit position; when the pen body 10 is at the left-tilt limit position, the angle between the second center line 92 and the first center line 91 is minus 30 degrees; when the pen body 10 is at the center position, the angle between the second center line 92 and the first center line 91 is 0 degrees; when the pen body 10 is at the right-tilt limit position, the angle between the second center line 92 and the first center line 91 is plus or minus 30 degrees. When the pen body 10 is between the left-tilt limit position and the center position, it is in a left-tilt state; when the pen body 10 is between the right-tilt limit position and the center position, it is in a right-tilt state. In some embodiments, the pen body 10 can be tilted and rotated within an angle range of plus or minus 20 degrees, and the range of plus or minus 20 degrees can adapt to the hand shape of most users.

[0058] The left and right tilt angles of the pen body 10 of the present application can be adjusted to meet different needs of different hand shapes, different pen holding gestures, different scanning habits, etc. For example, when the user's hand is small, the distance between the user's base and the pen body 10 is slightly smaller, and the tilt angle of the pen body 10 can be adjusted to a smaller angle; when the user's hand is large, the distance between the user's base and the pen body 10 is slightly larger, and the tilt angle of the pen body 10 can be adjusted to a larger angle; in this way, it can avoid the situation that the pen body 10 is too tilted and presses the base of the base, which is uncomfortable, and the hand is unevenly stressed, and the user is uncomfortable supporting the pen body 10, etc., and it can also avoid the situation that the tilt angle is too small to stably support the scanning pen, resulting in the first knuckle of the finger being laborious. For example, the left and right tilt angles are adjustable, and can also adapt to the different pen holding posture requirements of the user. When the user uses different holding gestures, the relative positions of the pen body 10 and the index finger and base are different. The user can adaptively adjust the tilt angle of the pen body 10 according to the pen holding posture and hand shape to comfortably hold the scanning pen and perform horizontal scanning actions.

[0059] The pen head 20 includes a second body 21, and two pen tips 22 are arranged at the bottom of the second body 21. The two pen tips 22 are arranged at intervals along the width of the scanning pen. When the scanning pen slides on the scanning surface, the pen tip 22 is used to contact the scanning surface to provide a fulcrum. The pen tip 22 has a contact surface 221. When scanning, the contact surface 221 of the pen tip 22 is against the scanning surface and slides on the scanning surface.

[0060] In one embodiment, the pen tip 20 further includes a contact member 24, which is disposed at the pen tip 22 and protrudes relative to the contact surface 221. The contact member 24 is an elastic structure or the contact member 24 is installed on the pen tip 22 via an elastic member such as a spring. The configuration of the contact member 24 can provide a buffer for the pen tip 20 to contact the scanning surface. The contact member 24 can be configured to be rotatable, and when the contact member 24 is rotatable, the scanning resistance can be reduced.

[0061] In this embodiment, the contact surface 221 is inclined upward from the front side of the scanning pen to the back side of the scanning pen, that is, the contact surface 221 faces backward and downward. Fig.10 , the scanning pen is shown scanning on the contact surface 221, in which the contact surface 221 of the pen tip 22 is in contact with or very close to the scanning surface. Fig.10 In the embodiment, the contact surfaces 221 of the two pen tips 22 are located in the same plane, which is the first plane.

[0062] like Figures 3 to 5As shown, the user's dominant hand is the right hand. When scanning, the pen body 10 is adjusted to a right-tilted state. The user holds the scanning pen in the right hand, with the right side of the scanning pen facing the user and the front of the scanning pen facing the left side of the user. The pen body 10 of the scanning pen is tilted toward the user relative to the pen head 20, so that the user can hold the scanning pen more comfortably and with less effort. In addition, the contact surfaces 221 of the two pen tips 22 of the scanning pen contact the scanning plane 93 at the same time, and the entire scanning pen is tilted to the right relative to the scanning surface. The user holds the scanning pen and slides from left to right to scan, so that the user's sliding scanning is smoother and more comfortable than scanning from right to left.

[0063] like Figures 6 to 8 As shown, the user's dominant hand is the left hand. When scanning, the pen body 10 is adjusted to a left-leaning state, the user holds the scanning pen with his left hand, the left side of the scanning pen faces the user, and the front of the scanning pen faces the right side of the user. The pen body 10 of the scanning pen is tilted toward the user relative to the pen head 20, so that the user can hold the scanning pen more comfortably and labor-savingly. In addition, the contact surfaces 221 of the two pen tips 22 of the scanning pen contact the scanning plane 93 at the same time, and the entire scanning pen is tilted to the left relative to the scanning surface. The user holds the scanning pen and slides from right to left to scan, so that the user's sliding scanning is smoother and more comfortable than scanning from right to left.

[0064] Fig.10 In the figure, the right side shows the scanning direction that is more comfortable when the scanning pen is used with the right hand, and the left side shows the scanning direction that is more comfortable when the scanning pen is used with the left hand.

[0065] When the pen body 10 is in a left-tilted state or a right-tilted state, the first center line 91 and the second center line 92 form an angle A therebetween, and the first center line 91 and the second center line 92 are both located in the first plane. When the pen body 10 is in a left-tilted state or a right-tilted state for scanning, since the contact surface 221 of the pen tip 22 is tilted relative to the front of the scanning pen and the contact surface 221 of the pen tip 22 abuts against the scanning plane 93, the first plane is tilted relative to the scanning plane 93, and the angle between the first plane and the scanning plane 93 is B.

[0066] In one embodiment, one or more of the first left side portion 102, the first right side portion 101, and the back side of the pen body 10 are provided with a finger-matching portion, and the finger-matching portion is used to match with the finger to facilitate the finger to support or hold the pen body 10. The finger-matching portion can be, but is not limited to, a matching groove or a matching convex pattern group. Based on the setting of the finger-matching portion, in combination with the structural design of the scanning pen of the present application, it can adapt to different holding requirements, and the holding and scanning experience is better.

[0067] The following provides an assembly method between the pen tip 20, the rotating mechanism 30, and the pen body 10.

[0068] The pen tip 20 is fixed to the rotating mechanism 30 , and the rotating mechanism 30 is rotatably mounted on the pen body 10 . When the rotating mechanism 30 rotates relative to the pen body 10 , the main body of the pen tip 20 is driven to rotate relative to the pen body 10 .

[0069] The acquisition module 40 is disposed in the rotating mechanism 30. Specifically, the rotating mechanism 30 includes a mechanism housing 31, the interior of the mechanism housing 31 has an installation cavity, the acquisition module 40 is disposed in the installation cavity, and the mechanism housing 31 is also provided with a scanning window 32, through which the acquisition module 40 can collect information of the scanning surface.

[0070] Along the width direction of the scanning pen, the scanning window 32 is located between the two pen tips 22. The scanning window 32 faces the scanning surface.

[0071] In order to prevent the pen tip 20 from blocking the acquisition module 40 and ensure that the acquisition module 40 effectively acquires the scanning surface information, the pen tip 20 is provided with an avoidance groove 23, the position of the avoidance groove 23 corresponds to the scanning window 32, and the acquisition module 40 scans the window 32 and the avoidance groove 23 to acquire the scanning surface information.

[0072] In order to make the structure of the scanning pen more reasonable, the pen body 10 is provided with a display screen 12, and the display screen 12 is located on the front of the scanning pen. The rotating mechanism 30 is provided on the back of the pen body 10. When viewed from the front, the rotating mechanism 30 is blocked by the pen body 10, and the appearance is beautiful and integrated. In this embodiment, a collection module 40 with a certain volume is provided in the rotating mechanism 30, and the rotating mechanism 30 is provided on the back of the collection module 40. Not only can the collection module 40 rotate synchronously with the pen head 20 to ensure that when the contact surface 221 of the pen head 20 abuts against the scanning surface, the collection surface of the collection module 40 is aligned with the scanning surface for information collection; it can also reduce the volume of the pen head 20. When viewed from the front of the scanning pen, there is no gap between the pen head 20 and the pen body 10, and the pen head 20 is small in volume and beautiful in appearance.

[0073] In order to improve the integrity of the pen body 10, refer to Fig.14 The back of the first main body 11 of the pen body 10 is provided with an embedding groove 111, and the rotating mechanism 30 is disposed in the embedding groove 111. Fig. 9 , Fig.10 The back of the rotating mechanism 30 is substantially flush with the back of the first body 11 , and it is not visible or substantially invisible that the rotating mechanism 30 protrudes relative to the back of the pen body 10 . When viewed from the side of the scanning pen, there is no sense of step difference between the rotating mechanism 30 and the pen body 10 .

[0074] In one embodiment, the pen tip 20 covers at least a portion of the back side of the pen body 10. Of course, the pen tip 20 may not cover the back side of the pen body 10.

[0075] The pen tip 20 can be arranged in at least two ways as follows.

[0076] The first setting method of the pen head 20 (refer to Figures 1 to 10 ):

[0077] The pen tip 20 covers at least part of the bottom surface and part of the side surface of the pen body 10, which can not only realize the rotational guide cooperation between the pen tip 20 and the pen body 10, but also prevent the pen tip 20 from covering the front of the pen body 10, so that the front of the pen body 10 is exposed. Figure 1 , Figure 3 , Figure 6 There is no step difference between the nib 20 and the pen tip 22. Based on the rotational cooperation between the nib 20 and the pen body 10, the rotating mechanism 30 is not visible. There is no other structure between the nib 20 and the pen body 10. The bottom of the pen body 10 can be designed to be arc-shaped. The nib 20 is designed to have an arc shape that matches the bottom of the pen body 10, which reduces the step difference between the nib 20 and the pen body 10 and improves the integrity.

[0078] The first body 11 of the pen tip 20 includes an elastic part, and the elastic part is provided with a sleeve groove; a part of the pen body 10 extends into the sleeve groove. The sleeve groove forms a slot opening at least on the front and the top thereof, so that the pen body 10 can be exposed or extended. Specifically, the front of the pen body 10 is exposed from the slot opening on the front of the sleeve groove, and the pen body 10 extends from the slot opening on the top of the sleeve groove. The elastic part of the pen tip 20 is sleeved outside the pen body 10, and the pen tip 20 is in contact with the pen body 10, so that after the pen body 10 and the pen tip 20 are relatively rotated to a certain angle, the pen body 10 can be kept at the current rotational tilt angle under the action of static friction. Of course, in other embodiments, a limiting structure can also be provided between the pen tip 20 and the pen body 10, or between the rotating mechanism 30 and the pen body 10, so as to keep the pen body 10 at multiple rotational tilt angles.

[0079] The second setting method of the pen tip 20 (refer to Figures 11 to 13 ):

[0080] Part of the pen tip 20 is embedded in the embedding groove 111, and the pen tip 22 at the bottom of the pen tip 20 extends out of the embedding groove 111 to protrude outward relative to the pen body 10. Specifically, the left and right sides of the embedding groove 111 have a first groove side wall 1111 and a second groove side wall 1112. The first groove side wall 1111 and the second groove side wall 1112 are used to shield the rotating mechanism 30 from the side on the one hand, and can also be used to cooperate with the pen tip 20 to achieve the rotation angle limit of the pen body 10, and limit the limit of the pen body 10 rotating to the left and right.

[0081] In one embodiment, the scanning pen further includes a sensing component, which is used to sense the relative angle between the pen tip 20 and the pen body 10, so as to sense whether the pen body 10 is in a left-leaning state, an upright state, or a right-leaning state.

[0082] In one embodiment, the sensing component is a rotary encoder disposed between the pen body 10 and the rotating mechanism 30, and the rotary encoder senses the rotation angle and rotation direction of the rotating mechanism 30, thereby sensing that the pen body 10 is in a left-leaning state, an upright state, or a right-leaning state. In another embodiment, the sensing component includes a first light emitter and a second light emitter disposed on the first groove sidewall 1111 and the second groove sidewall 1112, respectively, and a plurality of light receivers disposed around the pen head 20 or around the rotating mechanism 30. Different light signals are received by different light receivers to determine the angle between the pen head 20 and the rotating mechanism 30, thereby determining the left-leaning angle or the right-leaning angle of the pen body 10, thereby sensing that the pen body 10 is in a left-leaning state, an upright state, or a right-leaning state. In another embodiment, the sensing component includes a plurality of light emitters disposed on the bottom wall 113 of the first groove, and a plurality of light receivers disposed on the pen tip 20 or around the rotating mechanism 30 on one side close to the bottom wall 113 of the first groove. Based on different light signals received by different light receivers, the angle between the pen tip 20 and the rotating mechanism 30 is determined, thereby determining the left tilt angle or the right tilt angle of the pen body 10, thereby sensing whether the pen body 10 is in a left tilt state, an upright state, or a right tilt state.

[0083] The present invention further provides a scanning pen control method, which is applied to the scanning pen in any of the above embodiments. The scanning pen control method includes:

[0084] S100: determining the tilt direction of the pen body 10 or the pen tip 20, and determining whether the current use state of the scanning pen is a left-hand use state or a right-hand use state according to the tilt direction of the pen body 10 or the pen tip 20;

[0085] S200: Based on the current usage status of the scanning pen, control the operation of the scanning pen.

[0086] In one embodiment, in step S100, determining the tilt direction of the pen body 10 or the pen tip 20 includes:

[0087] According to the first sensing signal, determining that the current use state of the scanning pen is a right-hand use state;

[0088] According to the second sensing signal, it is determined that the current use state of the scanning pen is a left-hand use state.

[0089] The first sensor signal is sent by the sensor component, and after the controller receives the first sensor signal, it can be determined that the pen body 10 is currently in a right-leaning state after processing. The second sensor signal is sent by the sensor component, and after the controller receives the second sensor signal, it can be determined that the pen body 10 is currently in a left-leaning state after processing.

[0090] In the related art, it is generally assumed that the user holds the scanning pen with the right hand and scans from left to right to continuously collect information on the scanning surface, and then further processes the collected information, such as performing OCR recognition processing to recognize characters. The scanning pen in the related art cannot adapt to the left-hand scanning requirements.

[0091] In order to adapt to the scanning requirements of left and right hands, in one embodiment, in step S200, the collected information is processed in different ways according to the different use states of the scanning pen. When it is determined that the current use state of the scanning pen is the right-hand use state, the scanning pen is controlled to perform the first information processing step; when it is determined that the current use state of the scanning pen is the left-hand use state, the scanning pen is controlled to perform the second information processing step.

[0092] In one embodiment, the first information processing step and the second information processing step may be implemented in the following manner:

[0093] When it is determined that the current use state of the scanning pen is the right-handed use state, the general user will scan from left to right. During the scanning process, the acquisition module 40 will continue to take n images. Correspondingly, in the first information processing step, the control device splices the n images from left to right in sequence (that is, the second captured image is spliced ​​on the right side of the first image) to form a complete scan image, and then the characters in the complete scan image are identified by the recognition technology. After the characters are identified, the characters are displayed. When it is determined that the current use state of the scanning pen is the left-handed use state, the general user will scan from right to left. During the scanning process, the acquisition module 40 will continue to take n images. Correspondingly, in the first information processing step, the control device splices the n images from right to left in sequence (that is, the second captured image is spliced ​​on the left side of the first image) to form a complete scan image, and then the recognition technology is used to identify the characters in the complete scan image. After the characters are identified, the characters are displayed.

[0094] In other embodiments, the first information processing step and the second information processing step may be implemented differently from the above method, but may be implemented by other methods. As long as they can adapt to the right-hand scanning habits and the left-hand scanning habits respectively, the scanning results can be output normally and accurately when the scanning pen is held in different hands for scanning.
