Description

Technical Field

[0001] This invention relates to a document sorting, entry, and scanning device, and more particularly to a high-efficiency scanning device for automatically entering accounting documents into a computer. Background Technology

[0002] Accounting is the study of how businesses recognize revenue and assets within a specific operating cycle. Besides preparing financial statements and recording business transactions, accountants are also involved in mergers and acquisitions, quality management, the application of information technology in finance, tax strategies, and many other management decision-making activities. The field of accounting is broad, encompassing areas such as assurance, auditing, taxation, corporate accounting, management accounting, financial management, bankruptcy liquidation, forensic accounting, budgeting, and business consulting. The most crucial basis for accountants in these areas is negotiable instruments, which have broad and narrow definitions. Broadly defined, negotiable instruments include various securities and certificates, such as stocks, corporate bonds, invoices, and bills of lading. In a narrow sense, negotiable instruments, as defined in my country's "Negotiable Instruments Law," include bills of exchange, bank drafts, and checks. These are securities issued by the drawer, promising to unconditionally pay a certain amount to the payee or holder upon presentation or on a specified date. Therefore, negotiable instruments possess payment, remittance, credit, settlement, and financing functions, highlighting their importance in accounting. However, the numerous functions of negotiable instruments also lead to the problem of managing a large volume of documents during accounting work. Furthermore, with the development of network information, negotiable instrument information needs to be stored in computers, making the input of negotiable instruments into computers inevitable. This has led to the development of computer scanning devices to input paper negotiable instruments into computers, facilitating information exchange and accounting integration. However, current computer scanning devices still have some defects and shortcomings in their use, and the specific areas requiring improvement are as follows:

[0003] 1. Most computer scanning devices today cannot transmit invoices through the bottom of the scanning device for data entry. As a result, accountants inevitably have to manually input a large number of invoices one by one, which reduces the efficiency of the invoice scanning and data entry work of accountants to a certain extent.

[0004] 2. Most computer scanning devices today cannot push out or guide in documents, which to some extent affects the convenience for accounting personnel to put in and take out documents, thus causing inconvenience to accounting personnel.

[0005] 3. Most computer scanning devices today cannot be adjusted to handle invoices of different sizes, which makes it inconvenient for accounting personnel to use them and reduces the ease of use for accounting personnel to some extent.

[0006] 4. Most computer scanning devices today cannot flatten and stretch documents to a certain extent, which will affect the completeness and clarity of the electronic documents scanned by the computer scanning device, thus increasing the probability of accounting personnel having to rescan them.

[0007] 5. Most computer scanning devices today cannot provide adequate protection against vibration, thus failing to reduce the impact of vibration on document scanning and input, thereby reducing the quality of document scanning and input during vibration. Summary of the Invention

[0008] The purpose of this invention is to provide a high-efficiency scanning device for automatically entering accounting documents into a computer, in order to solve the problem mentioned in the background art that most current computer scanning devices cannot automatically sort and enter documents, which inevitably requires accountants to sort a large number of documents and enter them one by one, thus reducing the efficiency of accountants in scanning and entering documents to a certain extent.

[0015] As a preferred embodiment of the present invention, the feeding device includes a second fixed plate, which is fixedly connected to the front side of the front side fixing frame. A movable groove is formed within the second fixed plate, and two movable blocks are movably connected within the movable groove.

The controller output terminal is also electrically connected to a motor input terminal.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This invention controls the motor's operation via a controller. The motor's rotation drives the drive gear, which in turn drives the first mating gear. The first mating gear then drives the second mating gear in the opposite direction. The reverse rotation of the first and second mating gears drives the two rotating rollers in the opposite direction. During the reverse rotation of the two rotating rollers, the two auxiliary seats (first and second) provide positioning to ensure rotational stability. The rotation of the lower rotating roller also drives the first power pulley, which in turn drives the second power pulley via a power transmission belt. The second power pulley drives the auxiliary shaft, supported by two support blocks and two reinforcing ribs. The rotation of the auxiliary shaft drives the feed roller, which, combined with the downward pressure from the two pressing plates, moves the document backward. During this backward movement, the document is separated by a dividing groove, allowing individual documents to be separated. The receipt passes through two ironing sleeves and contacts them. The reverse rotation of the sleeves then irons the receipt and transports it backward. During this rotation, the four pairs of friction wheels at the front end, in conjunction with the four pairs of positioning shafts, drive the four pairs of transmission wheels at the front end to rotate in the opposite direction. This reverse rotation of the front four pairs of transmission wheels, in turn, drives the four pairs of transmission belts at the rear end to rotate in the opposite direction within two opposing C-shaped frames. The ironed receipt is then slowly transported through the main unit for image capture and data entry. This solves the problem that most current computer scanning devices cannot transmit receipts through the lower part of the scanner for data entry, inevitably requiring accountants to manually input large numbers of receipts one by one, thus reducing the efficiency of receipt scanning and data entry for accountants.

[0020] 2. This invention uses friction wheels to work in conjunction with four positioning shafts arranged in pairs at the front end, which in turn drive four transmission wheels arranged in pairs at the front end to rotate in the opposite direction. This rotation of the four transmission wheels in pairs at the front end, in turn, drives four transmission belts arranged in pairs at the rear end to rotate in the opposite direction within two opposing C-shaped frames. The ironed documents are then slowly transported through the main body. After passing through the main body, the documents are placed into two storage slots. This avoids the problem of documents being stored at the bottom of the main body, making it inconvenient for users to retrieve the entered documents. This solves the problem that most current computer scanning devices cannot push out or guide documents in, thus affecting the convenience of accounting personnel in placing and retrieving documents and causing inconvenience to accountants.

[0021] 3. This invention involves rotating one of four rotating rods, causing either adjusting pulley one or adjusting pulley two to rotate. Subsequently, the two adjusting pulleys two, in conjunction with adjusting transmission belt two, and the two adjusting pulleys one, in conjunction with two adjusting transmission belts one, cause the two bidirectional screws one, two, and three to rotate synchronously. During the synchronous rotation of the two bidirectional screws one, four sliding blocks arranged in pairs move within two sliding grooves, thereby causing the two C-shaped frames to move closer or further apart to accommodate documents of different lengths. During this movement, the two adjusting seats one, in conjunction with two adjusting rods and two adjusting seats two, move the adjusting frames up and down. During this movement, two limiting rails, two limiting posts, and two limiting holes ensure the stability of the adjustment, allowing the two C-shaped frames to move further apart to accommodate longer documents. The system can capture the entire document from a high position to ensure high-quality data entry. When the two-way screws rotate, they drive two adjusting blocks and two moving blocks to move within the adjusting and moving slots. As the two adjusting blocks move within their slots, they work in conjunction with two fixed blocks to move two placement blocks, thus aligning the two placement slots with the two C-shaped frames. When the two moving blocks move within their moving slots, they drive two feeding plates to move. During the movement of the two feeding plates, the auxiliary shaft ensures stability, allowing the two feeding plates to correspond to the two C-shaped frames. This solves the problem that most current computer scanning devices cannot be adjusted to handle documents of different sizes, making it inconvenient for accounting personnel to use them and reducing ease of use for accountants.

[0022] 4. This invention uses two rotating rollers with heating chambers inside, along with two corresponding positioning bearings, to ensure the relative stability and position of the two heating rods. Simultaneously, a protective tube, controller, and battery work together to heat the heating rods. During the heating process, the heat is transferred to two ironing sleeves. The reverse rotation of the two ironing sleeves then irons the document between them, flattening it. This allows the document to be fed more smoothly into the lower part of the main body for scanning and data entry. The flatness also prevents shadows caused by unevenness during the scanning process, thus avoiding incomplete data entry. This solves the problem that most current computer scanning devices cannot flatten and smooth documents to a certain extent, which affects the completeness and clarity of the scanned electronic documents, increasing the probability of re-scanning by accounting personnel.

[0023] 5. This invention transmits vibration to four hinge seats by setting a base plate. The vibration of the four hinge seats will cause the four damping plates to vibrate under the support of the four corresponding hinge shafts. At this time, the vibration is initially damped by four torsion springs. During the vibration of the four damping plates, the four hinge seats will vibrate up and down through four movable slots and four hinge shafts. During the up and down vibration of the four hinge seats, the damping springs, reinforcement frame and fixed column limit will provide secondary damping. During the up and down movement of the four hinge shafts, the four damping gears and four toothed plates will make the movement of the four hinge seats relatively stable and slow. In this process, the up and down vibration of the bearing plate can be slow and stable, thus avoiding the distortion of the input information caused by the shaking of the main body and the shaking of the document due to excessive vibration. This solves the problem that most current computer scanning devices cannot provide a certain degree of protection during vibration, and thus cannot reduce the impact of vibration on the scanning and input of documents. Therefore, it reduces the problem of the quality of scanning and inputting documents during vibration to a certain extent. Attached Figure Description

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figure 1-12 This invention provides a technical solution for a high-efficiency scanning device for automatically entering accounting documents into a computer:

[0039] An adjustment device 4 is provided at the upper end of the support device 1. A power device 3 is provided at the front end of the adjustment device 4. The power device 3 is connected to a feeding device 6. A placement device 5 is connected to the rear end of the adjustment device 4. The front end of the placement device 5 is fixedly connected to the support device 1. The rear ends of the power device 3 and the feeding device 6 are both fixedly connected to the support device 1. The upper and lower sides of the lower end of the support device 1 are respectively fixedly connected to the two ends of the protective telescopic sleeve 2. A controller 8 is fixedly connected to the rear end of the left side of the support device 1. The main body 7 is movably connected to the center of the upper end of the adjustment device 4.

[0040] The support device 1 includes a base plate 11. Each of the four corners of the base plate 11 is fixedly connected to a hinge seat 12. Each of the four hinge seats 12 is hinged to one end of a damping plate 13 via a hinge shaft 113. The other end of each of the four damping plates 13 has a movable groove 15. The movable groove 15 is designed to prevent the damping plate 13 from obstructing the damping process of the damping spring 110 during vibration-induced movement. Each of the four movable grooves 15 is movably connected to a hinge shaft 114. Each of the four hinge shafts 114 is movably connected to one of the four hinge seats 115. The four hinge seats 115 are fixedly connected to the four corners of the lower side of the bearing plate 117. Two damping gears 116 are fixedly connected to the outer surface of each of the four hinge shafts 114. Each of the four sets of damping gears 116 is connected to one of the four toothed plates 16. This ensures that the bearing plate 117 moves smoothly and stably during vibration, thus avoiding interference with the main body 7's recording of the ticket. The lower ends of the four toothed plates 16 are fixedly connected to the upper side of the base plate 11. The upper opposite surfaces of the four toothed plates 16 are respectively fixedly connected to the four ends of the reinforcing frame 19. The reinforcing frame 19 is movably connected to the fixing column 112. The upper end of the fixing column 112 is fixedly connected to the center of the lower side of the bearing plate 117, thereby helping to limit the position of the bearing plate 117 and ensuring the relative position and height stability of the bearing plate 117. The lower end of the fixing column 112 passes through the reinforcing frame 19 and is fixedly connected to the limiting plate 17. The upper end of the fixing column 112 is sleeved with a shock-absorbing spring 110. The two ends of the shock-absorbing spring 110 are respectively fixedly connected to the opposite surfaces of the bearing plate 117 and the reinforcing frame 19.

[0041] Each of the four hinge pins 113 has two torsion springs 14 fitted onto it, which in turn assist the shock-absorbing springs 110 in damping the vibration and preventing it from affecting the ticket entry work of the main body 7. The two sets of torsion springs 14 are fixedly connected at both ends to the four damping plates 13 and the four hinge seats 12 respectively. The left and right ends of the upper side of the bearing plate 117 are fixedly connected to the limit rails 119. The upper and lower inner walls of the two limit rails 119 are fixedly connected to the two ends of the limit posts 18 respectively, which connect to the C-shaped frame 46 and ensure the adjustment function. The front and rear ends of the two limit rails 119 are fixedly connected to the two fixing frames 11 respectively. On opposite sides, the lower ends of two fixed brackets 111 are fixedly connected to the upper side of the support plate 117. The center of the front and rear ends of the two fixed brackets 111 are provided with inlet and outlet slots 120 to ensure the functionality of ticket entry and delivery. At the same time, in order to ensure the adjustment function, the front and rear ends of the upper side of the support plate 117 are provided with sliding grooves 121. The left and right end walls of the two sliding grooves 121 are provided with movable holes 118. Adjustment devices 4 are movably connected in the four movable holes 118. The upper and lower ends of the protective telescopic sleeves 2 are fixedly connected to the opposite surfaces of the support plate 117 and the base plate 11.

[0042] The adjusting device 4 includes four sliding blocks 45, each with a screw hole at its center. These screw holes are threaded to the ends of two bidirectional screw rods 44. The ends of the two bidirectional screw rods 44 pass through four pairs of movable holes 118 and are fixedly connected to two adjusting pulleys 42 and two adjusting pulleys 411. The four sliding blocks 45 are movably connected within four sliding grooves 121. The four pairs of sliding blocks 45 are fixedly connected to the lower sides of two C-shaped frames 46. Adjusting seats 413 are fixedly connected to the upper sides of each of the two C-shaped frames 46. Each adjusting seat 413 is hinged to one end of an adjusting rod 414. Each adjusting rod 414 has an adjusting seat 415 hinged to its other end. The two adjusting seats 415 are fixedly connected to the left and right ends of the lower side of the adjusting frame 416. The left and right ends of the adjusting frame 416 are movably connected to the two limiting rails 119. The left and right ends of the two adjusting frames 416 are provided with limiting holes 417. The two limiting holes 417 are movably connected to two limiting posts 18, so that the position of the C-shaped frame 46 is adapted to the height of the main body 7. Thus, the C-shaped frame 46 can adjust the shooting and recording range of the main body 7 in conjunction with the adjustment of different lengths of tickets, thereby avoiding incomplete ticket information recording caused by the small shooting range of the main body 7.

[0043] A connecting hole 420 is provided at the center of the adjusting frame 416. The main body 7 is movably connected to the connecting hole 420. Protective plates 419 are movably connected to both ends of the main body 7. Positioning screws 418 are movably connected to the opposite ends of the two protective plates 419. The two positioning screws 418 are threaded to two threaded sleeves 421 respectively. The two threaded sleeves 421 are fixedly connected to the inner walls of the front and rear sides of the connecting hole 420. The main body 7 is an automatic capture and input ticket entry device. Two positioning shafts 48 are movably connected to the inner walls of the opposite ends of the two C-shaped frames 46. The opposite ends of the eight positioning shafts 48 are fixedly connected to the transmission wheels 410. Thus, the ticket can stably pass through the lower end of the main body 7 for information input via the transmission belt 49. The data entry is also for transmitting the tickets to facilitate subsequent retrieval by the relevant users. Eight pairs of transmission wheels 410 are connected by four transmission belts 49. Friction wheels 47 are fixedly connected to the outer surfaces of the opposite ends of the four front positioning shafts 48, so that the adjustment function is not affected during the power transmission process. The power device 3 is movably connected to the upper and lower pairs of the four front friction wheels 47. Two adjusting pulleys 411 are connected by adjusting transmission belts 412. Two adjusting pulleys 42 are connected by two adjusting transmission belts 43 to the feeding device 6 and the placement device 5 respectively. Rotating rods 41 are fixedly connected to the outer surfaces of the opposite ends of the two adjusting pulleys 42 and the two adjusting pulleys 411.

[0044] The power unit 3 includes a motor 31, with a drive gear 32 fixedly connected to the output end of the motor 31. The drive gear 32 is driven by a first mating gear 33, which is driven by a second mating gear 36. This causes the two rotating rollers 34 to rotate in opposite directions, guiding the tickets into four pairs of counter-rotating conveyor belts 49 for transport.

[0045] The feeding device 6 includes a fixed plate 2 61, which is fixedly connected to the front side of the front side fixing frame 111. A movable groove 63 is provided inside the fixed plate 2 61, and two movable blocks 64 are movably connected within the movable groove 63. The two movable blocks 64 are threadedly connected to both ends of a bidirectional screw 3 62. The right end of the bidirectional screw 3 62 passes through the right side wall of the movable groove 63 and is fixedly connected to an adjusting pulley 45. The adjusting pulley 45 is connected to the front adjusting pulley 42 via a front adjusting transmission belt 43, thus ensuring the linkage function of the adjustment. This allows the adjusting device 4, the feeding device 6, and the placing device 5 to correspond, thereby achieving the linkage of feeding and placing of documents. The purpose is to facilitate the placement and retrieval of documents by relevant personnel for document entry. Two feeding plates 66 are fixedly connected to the rear side of the front side of the two moving blocks 64. Each feeding plate 66 has a feeding groove 67. Each feeding groove 67 has a squeezing groove 68 on its inner wall. Two squeezing columns 610 are fixedly connected to the upper and lower inner walls of the two squeezing grooves 68.

The upper and lower ends of the squeezing spring 69 are fixedly connected to the opposite surfaces of the upper inner walls of the two squeezing plates 611 and the squeezing grooves 68.

[0046] Both extrusion grooves 68 have a dividing groove 612 at their lower rear ends. Both dividing grooves 612 are square through grooves with a triangular front end and a paper thickness at the rear end, which allows the documents to be separated and enter between the two rotating rollers 34 for transmission and input. The lower ends of the two feeding plates 66 are movably connected to auxiliary shafts 615. The two ends of the auxiliary shafts 615 are movably connected to two support blocks 613.

Each of the two placement blocks 57 is fixedly connected to a placement block 57. Placement slots 58 are provided on the opposite surfaces of the two placement blocks 57, which can store the entered tickets. At the same time, it can also make it convenient for users to take out and transfer the tickets through the gap between the two placement slots 58. The two placement slots 58 are set at the rear end of the two C-shaped frames 46, and the two partition slots 612 are set at the front end of the two C-shaped frames 46. The front and rear ends of the two C-shaped frames 46 are respectively set at the two inlet and outlet slots 120. The output end of the controller 8 is also electrically connected to the input end of the motor 31.

[0048] Specific operation method of the present invention:

[0049] Before entering the invoice, first place the main body 7 into the connecting hole 420 in the adjusting frame 416. Then, using the threaded holes on the front and rear side walls of the limiting hole 417, along with the corresponding two protective plates 419 and two positioning screws 418, position the main body 7 in the appropriate position within the connecting hole 420. Simultaneously, connect the main body 7 to the computer. Then, rotate one of the four rotating rods 41 as needed to enter the invoice length, thereby causing either adjusting pulley one 42 or adjusting pulley two 411 to rotate. Subsequently, the two adjusting pulleys two 411 can be used to adjust the... The transmission belt 412 and two adjusting pulleys 42 work together with the two adjusting transmission belts 43 to make the two double-screws 44, 54, and 62 rotate synchronously. During the synchronous rotation of the two double-screws 44, they will move within the two sliding grooves 121 through four sliding blocks 45 in pairs, thereby driving the two C-shaped frames 46 to move away from or towards each other to accommodate documents of different lengths. During the movement, the two adjusting seats 413 work together with the two adjusting rods 414 and the two adjusting seats 415 to adjust the frame 41. 6. The vertical movement position is adjusted by two limiting rails 119, two limiting posts 18, and two limiting holes 417 to ensure the stability of the movement adjustment. This allows the two C-shaped frames 46 to move away from each other, so that when the document is long, the main body 7 can capture the entire document from a higher position to ensure high-quality data entry. When the two bidirectional screws 54 and 44 rotate, they will drive the two adjusting blocks 55 and the two moving blocks 64 to move within the adjusting groove 53 and the moving groove 63, respectively. When the two moving blocks 64 move within the moving slot 63, they will move in conjunction with the two fixed blocks 56 to drive the two placing blocks 57 to move, thereby making the two placing slots 58 match the two C-shaped frames 46. When the two moving blocks 64 move within the moving slot 63, they will drive the two feeding plates 66 to move. During the movement of the two feeding plates 66, the stability of the movement will be ensured by the limiting of the auxiliary shaft 615, so that the two feeding plates 66 are set to correspond to the two C-shaped frames 46. After the adjustment is completed, the corresponding users can conveniently enter tickets of different lengths within a certain range.

[0050] After the adjustment and preparation are completed, first pull the two compression plates 611 to move them downwards and upwards. During the upward movement of the two compression plates 611, they will be limited by the two compression grooves 68 and the two compression columns 610. Then, the longer ends of the document can be placed on the lower end walls of the two feeding grooves 67 respectively. Then, the force of the two compression springs 69 can be used to press and position the document inside the two feeding grooves 67. After that, the controller 8 can control the motor 31 and the two heating rods 314 to operate. The rotation of the motor 31 will drive the drive gear 32 to rotate, the rotation of the drive gear 32 will drive the first mating gear 33 to rotate, and the rotation of the first mating gear 33 will drive the second mating gear 36 to rotate in the opposite direction. The reverse rotation of gear 33 and gear 36 will drive the two rotating rollers 34 to rotate in the opposite direction. During the reverse rotation of the two rotating rollers 34, the two auxiliary seats 35 and 38 will be used for positioning to ensure the stability of the rotation. During the rotation of the lower rotating roller 34, the drive pulley 37 will also be driven to rotate. The rotation of the drive pulley will drive the drive pulley 617 to rotate through the drive belt 618. The rotation of the drive pulley 617 will drive the auxiliary shaft 615 to rotate under the support of the two support blocks 613 and the two reinforcing ribs 614. The rotation of the auxiliary shaft 615 will drive the feed roller 616 to rotate. The rotation of the feed roller 616 will cooperate with the rotation of the two auxiliary rollers 33 and 36. The downward pressure of the two pressing plates 611 causes the document to move backward. During this backward movement, the document is separated by the dividing groove 612, allowing a single document to pass through and contact the two ironing sleeves 39. As the two rotating rollers 34 rotate in opposite directions, the heating chambers 312 inside each roller, along with the corresponding two positioning shafts 48 and bearings 313, ensure the relative stability and position of the two heating rods 314. As the two heating rods 314 heat the interior of the heating chambers 312, heat is transferred to the two ironing sleeves 39. Subsequently, the reverse rotation of the two ironing sleeves 39 removes the document that has entered between them. The ironing process involves ironing and conveying the ironing sleeve 39. During the rotation of the ironing sleeve 39, the four pairs of friction wheels 47 at the front end, together with the four pairs of positioning shafts 48 at the front end, drive the four pairs of transmission wheels 410 at the front end to rotate in the opposite direction. The reverse rotation of the four pairs of transmission wheels 410 at the front end, together with the four pairs of transmission wheels 410 at the rear end, drives the four pairs of transmission belts 49 to rotate in the opposite direction within the two oppositely arranged C-shaped frames 46. Afterward, the ironed document will be slowly conveyed through the main body 7. The main body 7 will then photograph the slowly passing document and record it into the computer. After the corresponding document passes through the main body 7, it will be sent into the two placement slots 58 for storage.

[0051] During the rotation of the ironing sleeve 39, the four friction wheels 47 at the front end, which are arranged in pairs, will work with the four positioning shafts 48 at the front end to drive the four transmission wheels 410 at the front end to rotate in the opposite direction. The reverse rotation of the four transmission wheels 410 at the front end will work with the four transmission wheels 410 at the rear end to drive the four transmission belts 49 to rotate in the opposite direction within the two oppositely arranged C-shaped frames 46. After that, the ironed ticket will be slowly transported through the main body 7. The main body 7 will then take pictures of the slowly passing ticket and record them into the computer. After the corresponding ticket passes through the main body 7, it will be sent into the two placement slots 58 for storage, thus avoiding the phenomenon that the ticket is stored at the bottom of the main body 7 and is inconvenient for the corresponding user to take out the recorded ticket.

[0052] During the reverse rotation of the two rotating rollers 34, the heating chambers 312 inside the two rotating rollers 34, together with the corresponding two positioning shafts 48 bearings 313, ensure that the two heating rods 314 do not rotate relative to each other and maintain their relative positions. During the heating process of the two heating rods 314 heating the inside of the heating chambers 312, the heat will be transferred to the two ironing sleeves 39. Then, the documents that have entered between the two ironing sleeves 39 can be ironed by the reverse rotation of the two ironing sleeves 39 to achieve the purpose of flattening the documents. This allows the documents to be fed into the lower part of the main body 7 for shooting and recording. During the shooting and recording process, the flatness also avoids the incomplete recording information caused by shadows due to unevenness.

[0053] If vibration occurs during the process of entering ticket information, the vibration will first be transmitted to the base plate 11. The base plate 11 will then transmit the vibration to the four hinge seats 12. The vibration of the four hinge seats 12 will cause the four damping plates 13 to vibrate under the support of the four corresponding hinge shafts 113. At this time, the vibration will be initially damped by the four torsion springs 14. During the vibration of the four damping plates 13, the four hinge seats 115 will also vibrate up and down through the four movable slots 15 in conjunction with the four hinge shafts 114. During the up and down vibration of the four hinge seats 115, the damping springs 110 will provide secondary damping in conjunction with the reinforcement frame 19 and the limiting of the fixed column 112. During the up and down movement of the four hinge shafts 114, the four damping gears 116 will work in conjunction with the four toothed plates 16 to make the movement of the four hinge seats 115 relatively stable and slow. In this process, the up and down vibration of the bearing plate 117 can be slow and stable, thereby avoiding the distortion of the entered information caused by the shaking of the main body 7 and the shaking of the ticket due to excessive vibration.

[0054] When it is necessary to inspect or clean the main body 7, the two protective plates 419 can be easily disassembled in conjunction with the two threaded sleeves 421 and the positioning screws 418, thereby facilitating the inspection or cleaning of the main body 7.
