Description

[0001] The present invention relates to a book scanner using a commercial camera and a flatbed scanner,

The present invention relates to image scanning for automatically shooting and scanning a book using a commercial camera and a flatbed scanner.

In order to make a paper book as a digital book, there is a method of shooting with an overhead camera while turning a book by one page, and a method of manually scanning a book page by a scanner without using a camera. This method is inconvenient because you have to turn the bookshelf one by one by hand.

Automatic book scanners come out to solve the inconvenience of manual operation. A number of different techniques have been used to make automatic book scanners: the bookcase is absorbed by a vacuum absorber, the bookcase is turned over with a braided arm, and the four bookshelves are folded in a bookcase One of them is the scanner that presses the edge from the top and shoots with the overhead camera. A similar robotic arm scanner with a bookcase vacuum pick-up plate uses a technique of scanning a bookcase with a specially designed dedicated scanner rather than taking a book with a camera, and flattening the bookcase with a roller. These scanners have become the technical background of the present invention.

The problem is that you have to change the manual scan and manual camera shooting automatically.

The problem of the above automatic scanners is that when the book shelf vacuum adsorption plate sucks the book shelf, the book shelves are often bundled with two or more bookshelves. Therefore, the issue of having to turn the bookshelves one by one,

In addition, the automatic book scanners have a disadvantage in that the pushing plate that presses the bookcase flatly presses only the edge of the bookcase (the lateral direction), so that the bookcase is not flattened as a whole. Therefore, the problem that the bookcase should be spread out as a whole,

In addition, when the L-shaped robot arm rotates 180 degrees, that is, when one bookcase is completely turned over, the bookcase suction plate is attached to the bookcase under the turned bookcase, so the suction plate must escape through the bookcase. In order to do so, the robot arm has to be operated long, so that the product has to be enlarged. Therefore, it is necessary to minimize the motion of the robot arm in order to miniaturize the product,

In addition, the automatic book scanners use only a camera or only a scanner. Although automatic book scanners that shoot with cameras have a faster shooting speed, there is a drawback that they are not as sharp as scanned by a scanner when printing shot files, and automatic book scanners that are scanned by a scanner have a slower scan speed There is a distinct advantage in that the output of the file is different from the one captured by the camera. Therefore, the advantages of photographing by camera, the advantages of scanner by scanner, the problem of taking both of these methods,

Also, the biggest problem with automatic book scanners is that it is difficult for individuals or small businesses to buy because most of them are expensive. Therefore, it is necessary to lower the manufacturing cost of the product to popularize it.

The present invention adopts a technique of automatically turning a bookcase with a L-shaped robot arm to solve the drawbacks of manual photographing and manual scanning,

Also, because of the problem of the automatic scanner of the robotic arm attached to the bookshelf pickup plate, the book shelves are not handed one by one, but the problem is frequently prevented that the two or three sheets are handed over together. Two compressed air nozzles are used for the bookcase vacuum suction plate.

In addition, when the book shelf handled by the robot arm is flatly spread, the pressing of the edge of the book shelf with the pressing iron is performed incompletely, so that the present invention uses the following technique in order to flatten the book shelf as a whole.

When the transparent glass plate moves horizontally and is positioned directly above the bookcase, the transparent glass plate faces the turned bookcase. In order to allow the bookcase to be squeezed onto the transparent glass plate, the left and right bookstacks beneath the right and left shelves vertically rise and squeeze the right and left shelves so that the bookcase is flattened as a whole.

In order to solve the problem that the robot arm is long in operation, it is necessary to use a reciprocating motion of the air cylinder to minimize the operation of the robot arm.

Also, in order to take advantage of both the advantages of photographing by a camera and the advantages of a scanner by a scanner, that is, both methods, a commercial camera and a flatbed scanner are commonly used in the product of the present invention.

In addition, in order to lower the manufacturing cost of expensive automatic scanner products, special commercial cameras and general-purpose flatbed scanners (products that can be used upside down) are used instead of dedicated special cameras and special scanners.

Unlike most automatic book scanners, the present invention is advantageous in that both a camera and a scanner are used in combination with a scanner and an ordinary flatbed scanner. To make it easier for individuals as well as small businesses to purchase.

[Example 1]

Explanation of manual operation for preparation of camera shooting.

In the following description of the present invention, it is assumed that a general commercial camera is used.

The camera can be shot with the remote control, and any product can be used as long as close-ups can be taken to clearly capture the letters in the book.

A tripod is preferable if it is a vertical tripod capable of shooting a bookcase in front.

A camera is mounted on a tripod, and a tripod is mounted on the outside of the present invention, i.e., behind the robot arm, so that the camera photographs the bookcase in front.

Turn on the lamp 30 and place the book on the left and right bookstore (400).

The right and left bookcases are raised / lowered by using the manual button on the control panel 20 so that the left and right bookcases whose height is different are horizontally aligned. Then, the transparent glass plate 200 is horizontally moved by using the manual button on the control panel 20 So that the transparent glass plate 200 comes directly above the bookcase.

Next, the bookshelf is pressed on the transparent glass plate 200 by the vertical upward movement of the left and right bookcases to make them flat.

Set the camera shooting and manually press the camera remote control button on the control panel (20) to check the image status of the bookcase.

[Example 2]

&Quot; Example 2 " refers to automatic motion.

In the present invention, automatic photographing / scanning is performed by four-step motion.

In step 1, the braided arm of the robot with the book shelf vacuum suction plate 100 is rotated 180 degrees to transfer the absorbed bookcase.

The transparent glass plate 200 moves horizontally by the drive motor 301 equipped with the transparent glass plate 200 conveying portion in the second stage, and the transparent glass plate 200 goes directly to the turned bookcase.

It is a work to flatten the left and right bookshelves curved to the curved surface like the third stage, half moon.

By the vertical motion of the booklet holder 400 (FIG. 10), the bookshelf rises and the left and right bookshelves are pressed onto the transparent glass plate 200, thereby making the bookshelves flat.

In step 4, the camera takes a picture of the bookcase squeezed on the transparent glass plate 200. When using the flatbed scanner, the scanner scans.

Hereinafter, the rotational motion of the L-shaped robot arm will be described.

Press the automatic switch on the control panel (20) to start the machine.

The booklet vacuum adsorption plate 100 is moved to the right side of the bookcase and the bookcase is ready to be adsorbed.

By the operation of the air compressor 113, the book-wound vacuum adsorption plate 100 starts to adsorb a sheet of book.

[Example 3]

Explanation of compressed air injection of the book shelf vacuum adsorption plate (100).

When the book shelf vacuum adsorption plate starts to adsorb and start to rotate, the compressed air in the lateral direction 102 and the compressed air in the longitudinal direction 101 of the bookcase eject the compressed air by the operation of the air compressor 113. Then, the other paper sheets adhering to the one bookcase adsorbed on the bookcase vacuum adsorption plate 100 are separated and fall down.

When the robot arm rotates 180 degrees and completes the rotation, the book-space vacuum attracting plate 100 comes to the left side of the bookcase (the left side of the representative drawing 1). A book shelf vacuum adsorption plate (100) is placed directly below a turned bookcase, and a vacuum adsorption plate is placed just above the left shelf. That is, in the state in which the book shelf vacuum suction plate 100 is sandwiched between the bookshelf, the left rotation motion of the robot arm is completed.

[Example 4]

Description of the vertical motion of the book shelf vacuum adsorption plate (100).

When the bracket type robot arm completes the left rotation movement, the vacuum adsorption plate 100 is placed on the left side bookcase, and the book vacuum absorption plate 100 is sandwiched between the bookshelves. You have to get out of the bookshelves.

The book shelf vacuum attracting plate 100 is lifted vertically to perform the above operation.

In the eye view, it seems to move horizontally to the left. Then, the vacuum suction plate vertical support 105 and the vacuum suction plate height adjuster 106 are lifted vertically by being removed from the rotary motion shaft 109 and the vacuum suction plate vertical support connection pipe 108.

This movement is made by the vertical movement of the air compressor 113 and the reciprocating rod 124 attached to the air cylinder.

When the vacuum adsorption plate leaves the space between the bookshelf to the left side, the book shelf vacuum adsorption plate 100 completes the vertical rise.

[Example 5]

Explanation of horizontal movement of the transparent glass plate transferring unit 201 and the drive motor support 300.

When the rotational movement and the vertical movement of the book-holder vacuum suction plate 100 are completed, the transparent glass plate 200 positioned at the right side of the book is moved in the direction of the book by the driving of the transparent glass plate conveyance unit 201 and the drive motor 301, The horizontal movement is started.

When the transparent glass sheet 200 is horizontally moved, a sufficient space with the bookcase is secured so that the bookcase is not caught or damaged by the horizontal movement of the transparent glass sheet. This is accomplished by lowering the left and right baluns at the same motor speed when the automatic start switch is pressed.

In this state, the transparent glass plate 200 horizontally moves leftward toward the bookcase along the guide rail 10, and when the movement is completed, the left and right bookshelves are completely inserted under the transparent glass plate 200 and ready for photographing with the camera.

[Example 6]

Explanation of vertical uplifting motion of the left and right bookholder (400).

Although the left and right bookshelves are located under the transparent glass plate (200) and are ready to be photographed by the camera, the shape of the bookcase is curved like a half moon on both sides, so it is necessary to flatten the left and right bookshelves. This work is performed by vertically moving the left and right bookcases 400 by vertical movement of the bookbinding vertical movement part (FIG. 10), pushing up the left and right bookcases and pressing them on the transparent glass plate 200. In other words, left and right bookshelves curved in a curved surface such as a half moon are pressed between the transparent glass plate 200 and the bookstore to be flattened under pressure.

The vertical motion of the booklet vertical movement part (FIG. 10) is as follows.

When the screw bar 401 is rotated by the motor 405, the female screw 402 moves up and down. However, the female screw 402 is fixed to the female screw fixing plate 403, The lower cover plate 411 is vertically moved up or down together with the rectangular parallelepiped guide rail 408 fixed to the lower cover plate 411. The guide rails move up and down through the rectangular parallelepiped guide rail grooves 409.

The motor support 407 fixed to the screw bar rotation motor 405 and the ball bearing 406 moves vertically up and down like the lower support plate 411.

[Example 7]

A description of the flat work of the bookcase and the structure of the booklet (Fig. 11).

When the bookbinding lower plate 411 vertically rises and pushes the bookbindle up to the transparent glass plate 200 to press the bookbelt smoothly without damaging the book, the bookbinding plate is divided into two layers: the bookbinding unit 400 and the lower- 411).

A ceramic buble sponge 412, which is a stretchable material, is inserted between the booklet 400 and the lower cover plate 411. 11, a pair of magnetic sensors 413 are attached to the bookbinding unit 400 and the lower cover plate 411) so that the bookcase can be photographed under optimum conditions.

The pair of magnet sensors 413 function to stop the screw bar rotation motor 405 when they come into contact with each other. When a bookshelf is sandwiched between the transparent glass plate 200 and the booklet 400 and is flattened in an optimal photographing state under pressure, the pair of magnet sensors 413 are brought into contact with each other so that the motor of the left and right booklets, (405) is stopped and the vertical rise is completed.

The magnet sensor 413 serves as a safety plate for stopping the screw bar rotation motor 405 when the billet reaches the upper limit of the upward movement. For example, even when the booklet is not placed on the booklet or when the transparent glass plate 200 is taken out, when the booklet 400 is raised and pressed when it touches the bottom of the transparent glass plate / scanner transferring unit 201, And the screw bar rotating motor 405 is stopped.

[Example 8]

Explanation of camera photography.

When the bookshelf is pressed onto the transparent glass plate 200 and the motors of the left and right bookcases, that is, the screw bar rotation motor 405 are all stopped and the booklet 400 completes the vertical rise, the push bars 504 of the camera remote- Presses the camera remote control to take a picture of the bookcase.

[Example 9]

Explanation of horizontal maintenance of left and right bookcases and vertical upward movement of left and right bookcases 400.

The thicker the book, the higher the height of the left bookcase and the right bookcase. When the bookshelf is passed from the right to the left, the height of the left bookshelf increases because the bookshelves accumulate on the left bookshelf, and the height of the right bookshelf decreases because the number of bookshelves decreases on the right.

When the left and right bookshelf are pressed against the transparent glass plate 200 and the booklet 400 and the pair of magnet sensors 413 attached to the booklet lower layer plate 411 come into contact with each other to come into contact with each other, When the bar rotation motor 405 stops and the vertical elevation of the booklet is completed, the height of the left and right bookcases becomes horizontal, and the curved surface of the left and right bookcases spreads and becomes flat.

As a result of the ascending movement, the left and right bookcases become completely horizontal irrespective of the height of the left and right bookcrests. When the screw bar rotation motor 405 is stopped, each time a book is turned over, the left book pile is lowered by one sheet thickness, and the right book pile is raised by one sheet thickness. In other words, it is the same as controlling the left and right screw bar rotation motors 405 so as to obtain the above results.

This horizontal holding method of the left and right bookcases can be said to be more accurate than the method of controlling the left and right screw-bar rotating motors 405 by a program.

[Example 10]

Description of the maintenance of the horizontal height of the left and right bookshelves and the descent of the left and right bookshelf 400.

When the transparent glass sheet 200 is moved horizontally to the right to return to its original position, a sufficient space must be maintained between the transparent glass sheet 200 and the bookcase to prevent the bookcase from being damaged.

In order to carry out the above operation, the left and right bookshelves must descend. When the left and right bookstocks descend, the screw bar rotation motor 405 is controlled and set so that the left and right bookstocks descend to the same length (e.g., 2 to 3 cm), that is, at the same motor revolution speed. The left and right bookshelves are kept horizontal, and the space of the bookcase and the transparent glass plate 200 is secured.

The completion of the booklet lowering motion is a prerequisite for the return of the transparent glass plate transferring unit 201 to the home position and the return of the bookcase vacuum suction plate 100, that is, the robot arm to the home position.

[Example 11]

Description of returning the original position of the transparent glass plate transferring unit 201 and returning the original position of the bookcase vacuum suction plate 100 to the home position.

The transparent glass plate 200 moves away from the book horizontally to the right and returns to the original position, and the robot arm rotates 180 degrees and returns to the original position. During the rotation of the robot arm, the vacuum adsorption plate vertical support 105 and the vacuum adsorption plate height adjuster 106 also descend to return to the original position, and a sheet is ready to be adsorbed again.

[Example 12]

A description of the camera remote control and PC mouse push device.

The camera remote control pushing device uses the electromagnetism principle, and includes a coil 503 for generating magnetism, two iron plates 501 and 502, push rods 504 and 505 with rubber attached to the ends, and a spring 506 for spreading two iron plates Consists of.

In FIG. 12, when the steel plate 502 is fixed to the case of the apparatus, the steel plate 501 and the coil 503 move horizontally each time a current flows.

When current is applied to the coil, push bars (504, 505) protrude forward and push the remote control of the camera or click the pc mouse by the attraction of the iron plate. When the current is interrupted, the push rods 504, 505 return to the home position.

With this device, you can use any camera that can shoot with the remote control. When using the scanner, click on the PC mouse with this device.

If the scanner product can be used independently from the PC, the device can be inserted into the mouse pusher cradle 509 and used.

[Example 13]

A description of an automatic book scanner using a flatbed commercial flatbed scanner.

The mechanical operation when using a general commercial camera has been described above.

Now, the use of a general commercial flatbed scanner will be described.

With the present invention, there is no great difference when using a commercial camera and when using a commercial flatbed scanner.

When shooting with an ordinary commercial camera, take a picture of a bookcase squeezed on a transparent glass plate.

However, when using a general commercial flatbed scanner, the general commercial flatbed scanner product is turned upside down and mounted on the transparent glass plate / scanner transfer unit 201. That is, the transparent glass plate of the flatbed scanner product is scanned while facing the left and right bookshelves. Therefore, the transparent glass plate of the flatbed scanner product has the same function as the transparent glass plate 200 when the camera is taken.

When scanning with a flatbed scanner, the transparent glass plate 200 is taken out of the transparent glass plate / scanner transfer unit 201 and scanned to prevent image quality deterioration.

This is different from when shooting a camera.

If the size of the bookshelf is too large to be able to scan the left and right bookshelf at a time when using the scanner, only one page can be scanned. In such a case, rotate the scanner product 90 degrees. In other words, it should be mounted horizontally and vertically.

Another point is that a PC mouse is used in place of the camera remote controller in Fig. 12, and all other machine operations are the same as when using a commercial camera.

Therefore, the description of the mechanical operation is omitted.

Depending on whether the present invention is compatible with flatbed scanner products, ie whether the scanner product can be scanned upside down, the general commercial flatbed scanner product can be classified into three types.

In most commercial flatbed scanner products, the scan module feed, which is a collection of black plastics, travels along guide rails, usually made of long cylindrical aluminum rods. Therefore, classification according to the position of the aluminum rod is as follows.

First, products on both sides of the aluminum rod.

Second, the aluminum rod is in the center of the product.

Third, the aluminum rod is located on either the left or right side of the product.

The first and second product families can be used with scanner products turned upside down. This is because the scan module feeder does not rub or fall and cause friction when the scanner is turned upside down.

In the third product line, when the flat scanner is scanned upside down, the scan module feeder tilts to the side where there are no guide rail aluminum rods, which may touch the edge of the transparent glass plate or the scanner cover and cause friction. have.

There are two ways to solve this problem. In one simple way, attaching a mini-wheel to the frictional part, the scan module plastic bundle, is a simple solution.

The other is a method of inserting an aluminum rod, which is a guide rail, and inserting a circular ring into the plastic bundle of the scan module feeding chain, and inserting it into the aluminum rod.

However, the third product family has to open the scanner product and insert the above parts inside, so it has to deal with the scanner manufacturer or order the production. If the performance of the scanner product is very good, you can use it with this product if you agree with the scanner manufacturer.
