JP6217039B2 - Document photographing device - Google Patents

Description

The present invention relates to article image capturing apparatus for capturing an as books in a digital camera.

  There are two types of devices for photographing materials such as books. One is a flatbed scanner or copying machine (for example, patents) that takes a picture through a transparent plate by scanning the line sensor over several seconds to several tens of seconds by pressing the book against a transparent plate. Document 1), or an automatic paper feeder (ADF) type scanner or copying machine (for example, refer to Non-Patent Document 1) that moves a document one sheet at a time for several seconds to several tens of seconds and images it with a line sensor. The other is a camera that uses an area sensor used in a digital camera or the like, and instantly photographs materials such as books and three-dimensional objects (see, for example, Patent Document 2).

  A document photographing apparatus of a type using a line sensor has a disadvantage that it takes a long time of several seconds to several tens of seconds for photographing. Flatbed scanners and copiers that use line sensors have the advantage of being able to flatten the book by opening the book and pressing it against a transparent plate by hand, but scanning the line sensor for seconds to tens of seconds There is a demerit that the book that is being pressed by the hand moves during the shooting time and the shot image is blurred. In addition, with automatic paper feeder (ADF) scanners and copiers that move the documents one by one and shoot them with a line sensor, you cannot shoot a bound book as it is, but use a blade as the back cover. There is a demerit that it is not possible to shoot unless it is cut and put one by one, the book must be damaged, and a public book such as a library cannot be taken.

  As a type using an area sensor used in a digital camera or the like, a method of photographing a spread book with a digital camera from the top is often sold (for example, Patent Document 3 (FIGS. 6 and 7)). 4 (see FIG. 10), Patent Document 5 (FIG. 7), and Non-Patent Document 2), since the book can be taken instantaneously, there is an advantage that the book is not shaken and a three-dimensional object or moving picture can be taken. However, when shooting a book, the book will naturally close if you do not hold the corners with your fingers, or the finger you are holding will be reflected along with the book. There is a demerit that the shutter button cannot be pressed when using. Also, the shadow of the digital camera above the book is often reflected in the document due to the lighting in the room, and there is a demerit that cannot be captured clearly. Furthermore, if the digital camera is too close to the subject, it will not be in focus, or for reasons such as high cost and reduced image quality when using a wide-angle lens, it will not be able to shoot unless it is about several tens of centimeters away from the subject. There is a demerit that the entire device becomes larger without being thinner than a flatbed scanner.

  In the type using an area sensor used in digital cameras, etc., the transparent plate and the digital camera are integrated to spread the book on a square table to improve the disadvantages such as difficulty in copying the book flat. By placing a transparent plate in the shape of a dog-shaped body that is integrated with the digital camera from above and shooting through the transparent plate, a flat imaging surface without having to hold the four corners with your fingers Has been devised (see, for example, Non-Patent Document 3). Still, since the digital camera cannot be photographed unless it is separated from the subject by several tens of centimeters, the digital camera cannot be made thinner than a flatbed scanner, and the entire apparatus is large.

  Furthermore, in the type using an area sensor used in a digital camera or the like, in order to improve a demerit such as an increase in the size of the entire device, there is a device that requires an effect of thinning the device using a reflection mirror (for example, And Patent Document 6). Nevertheless, since the reflecting mirror is used, there are disadvantages such as an increase in the failure rate due to an increase in the number of parts and a poor portability due to its increased weight.

  Flatbed scanners that use mainstream line sensors for book photography are mainly for A4 paper, and can be used for books, notebooks, magazines, catalogs, map books, etc. There are so many materials that cannot be photographed that they cannot be used in practice. Flatbed scanners are also available for A3 paper, but the price is very high for general home use because the line sensor, which is a major component, must be lengthened compared to A4 paper. In addition, there are disadvantages such as a high price and a long photographing time for scanning by the line sensor. Further, even if a mirror is used (for example, see Patent Document 6), it is necessary to enlarge the mirror, and since the angle is provided in the mirror, the entire apparatus becomes large. .

    The present invention includes an upper surface portion and a bottom surface portion, the upper surface portion and the bottom surface portion.Because it was folded close Depending on the structureA connecting portion that is connected, and the connecting portion is movableThe upper surface and So that the bottom portion is provided with a groove for storing the connecting portion.Can be folded, The thickness is folded so that the upper surface portion and the bottom surface portion are in contact with each other and the upper surface portion and the bottom surface portion are combined. Wait,The upper surface portion is at least partially made of a transparent body, and a camera that photographs a subject placed on the upper surface portion on the bottom surface portionIs installedThus, the object can be solved by providing a material photographing apparatus characterized in that the object can be photographed from the bottom surface through the transparent body.

  Also, because of the disadvantages of using an area sensor used in digital cameras, etc., it is not possible to focus unless it is several tens of centimeters away from the subject, or because of high cost and low image quality when using a wide-angle lens. In addition, in order to solve the problem of separating the camera from the subject and increasing the overall size of the device, it is possible to design the main body with reference to a structure in which the main body is thin and foldable, such as folding folding boxes and folding containers. desirable. The folding return box and the folding container are, for example, the perspective view of the conventional folding container shown in FIG. A structure that can be assembled into a box shape at the time of use by being provided with a convex portion or the like that fits into the concave portion or the like, and can be folded and thinned when stored or carried.

The collapsible structure such as a folding returnable boxes and folding containers with reference of the main body structure, using the transparent plate on the upper surface of the body, you established the lens or the like of the camera function on the bottom It is desirable. It is desirable that the lens or the like for the camera function is directed upward from the bottom surface portion so that the entire plate of the transparent portion on the top surface portion can be seen. A shutter button and the display monitor or the like each part of the camera function is installed in an orientation which can be operated from above, these respective parts of the camera function can also be arranged in the bottom part, easy to operate as the electric wire to the parts of the connecting portion of the body It may be installed on the top surface by passing through or using radio. Furthermore, a remote controller may be attached as a separate part or operated from a portable terminal such as a cellular phone using a wireless function. When photographing a book, the book is made flat by pressing the facing side of the book facing down on a transparent plate and photographed through the transparent plate. After shooting, the connecting part of the main body is moved and thinned to facilitate storage and carrying.

FIGS. 1-7 illustrate an embodiment of the present body.

Embodiment, slimming consolidated portion in a columnar shape, each part of the camera function is distributed, a groove for accommodating the posts provided on collapse the top portion and the bottom portion, rather thin, is obtained by weight. About the thinness of the embodiment , it can be the thickness of the top and bottom parts of the main body, and it is about the thickness of two digital cameras that often compete for thinness. It is not necessary to attach it behind the lens and can be arranged in a dispersed manner, so that it can be made thinner. Other forms, good connection portion even etc. such as pantograph structures such as pantograph jack.

The camera is preferably a type of camera that uses an area sensor used in a digital camera or the like.

  The present invention has the merit of using the line sensor, and has the advantage that the imaging surface can be flattened by opening the book and pressing it against a transparent plate, and the disadvantage of the type using the line sensor. There is no demerit that it takes a long time of several seconds to several tens of seconds, and the book that is being pressed by the hand moves during the shooting time and the shot image blurs.

  With automatic document feeder (ADF) scanners and copiers that move the documents one by one and shoot them with a line sensor, you can't shoot the bound book as it is, but cut the back cover with a blade, Although there is a demerit that it is impossible to shoot unless it is made one by one, the book must be damaged, or a public book such as a library cannot be taken, but the present invention does not have such a demerit.

The present invention, which is an advantage of using an area sensor used in a digital camera or the like, can shoot instantaneously, so that the book does not blur. Since the area sensor can take a wide range of focus, it is often used for scanners and copiers that use line sensors that cannot be read because the center part of the book that has been bound is not flat and dark or out of focus. There is no demerit when shooting books according to the present invention .

Since the present invention uses a foldable structure such as a folding return box or a folding container, it is a demerit of the type using an area sensor used in a digital camera or the like. The entire device becomes large because it cannot be focused unless it is separated, and there is no demerit that storage and portability after use deteriorate . Than those size of the apparatus using a reflection mirror (see Patent Document 6), it is storability and portability resistance.

  The mainstream flatbed scanners for book photography use a motor or gear to move a movable precision component called a line sensor, so it has low impact resistance when carried. Compared to this, the present invention is a digital camera or digital camera. Has impact resistance equivalent to that of mobile phones. Furthermore, since the zoom function of the camera function can be omitted, or the focus adjustment function can be omitted because the distance from the bottom surface to the top surface is constant, the number of parts can be reduced, further improving the shock resistance, The failure rate can be kept low.

  Most of flatbed scanners or automatic paper feeder (ADF) scanners that use mainstream line sensors for book photography are compatible with A4 paper, but the present invention wants to shoot larger documents of A4 or higher. In this case, for example, the additional cost for changing the size of A4 to the size of A3, for example, only needs to extend the connecting portion to increase the distance between the camera and the subject, and a wider shooting range can be obtained. Compared to a scanner that uses a line sensor, it is possible to shoot A3 paper or larger. In addition to extending the connecting portion long, a method using a wider angle lens may be used. As a result, a document photographing device that can shoot large materials such as books, notebooks, magazines, catalogs, map books, architectural drawings, children's drawings, etc. that exceed A4 will be manufactured much lower than conventional scanners and copiers. Can be provided at a cost.

  There are many types of copiers that use line sensors in convenience stores, schools, and businesses, and they are familiar with usage from children to the elderly. The operation of copying a book etc. with a copier is to repeat the same action again by turning the page with the other hand, pressing it with one hand, pressing the copy button with the other hand, turning the page In terms of operation, the present invention shoots a book or the like with the same operation as that of the copying machine, so that it becomes an operation that many people are accustomed to and has the advantage of being easy for both children and elderly people to use.

  The present invention has all these advantages.

As in FIGS. 1-7, the thinness of the case's folding Ritatan is a two component thickness of the upper surface portion and the bottom portion of the body. In other words, it is about the thickness of two digital cameras that often compete for thinness, or each part of the camera function is dispersedly arranged, or each part of the camera function on the upper surface part is thinned, so that it is thinner than that. can do. Therefore, using a motor or gears to move the line sensor, it can be made thinner than the mainstream flatbed scanner in book shooting.

Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.
FIGS. 1 and 2 of the embodiment show a state in which a foldable main body is unfolded and photographed, and a book is placed face down on a transparent plate 2. The book is made flat by pressing the facing surface of the book facing down on the transparent plate 2 on the upper surface, and photographed through the transparent plate.

  The camera has the same functions as a general-purpose digital camera using an area sensor. In addition to the functions of a general-purpose digital camera, the storage device may include not only the storage device 53 such as an SD card but also an external interface such as a USB terminal and a wireless connection function such as Wi-Fi. The illuminating unit 55 may be not only a flashing momentarily attached to a general-purpose digital camera but also an LED bulb that is always lit. The arrangement of each part of the camera function is not arranged on the back surface of the lens as in a general-purpose digital camera, but is arranged in a distributed manner for easy operation from the top and reduction in thickness.

3, 4 embodiment is a state in the process folding body is folded, the pillar-like and going on part of the connecting portion is movable.

5 and 6 of the embodiment show a state in which the foldable main body is folded . In embodiments, each part of the camera function is distributed, a groove for accommodating the posts provided on collapse the top portion and the bottom portion, rather thin, it lighter. About the thinness of the embodiment , it can be the thickness of the top and bottom parts of the main body, and it is about the thickness of two digital cameras that often compete for thinness. Without attaching to the back surface of the lens, each part of the camera function can be arranged in a distributed manner, or each part of the camera function on the upper surface part can be thinned to make it thinner. Therefore, since a portable terminal such as a mobile phone equipped with a digital camera has a thickness of less than 1 centimeter, an extremely thin document photographing device can be provided. Therefore, it can be made much thinner than a mainstream flatbed scanner in book photography that uses a motor, gears, etc. to scan the line sensor.

  Books and documents to be photographed vary in size, and books may be placed at an angle, but automatically recognize the difference between the book and the background and cut out only the book part or automatically correct the tilt There exists an image processing program to be executed (see Non-Patent Document 5, for example). In addition, image distortion that occurs when using a wide-angle lens, such as a fisheye lens, is also automatically corrected, as in the case of a 360-degree camera that converts images into a plane photo. There are image processing programs that can be used.

  The present invention can also be used in presentations, lectures, seminars, conferences, etc. as shown in the document presentation device of Japanese Patent Laid-Open No. 5-308547. The problems of the conventional document presentation apparatus presented by the above-mentioned Japanese Patent Laid-Open No. 5-308547, for example, the problem that the book is not flat and difficult to shoot can be solved.
