Description

Flat and Surface Image Scanner system

The present invention relates to a scanner that scans flat and curved images, and in more detail, by configuring a plurality of scanners consisting of lenses and sensors, a plurality of lenses and sensors correspond to targets to be scanned according to their respective positions. The present invention relates to a flat and curved image scanner system capable of scanning not only a flat image but also a curved image without distortion, without causing distortion caused by a lens or a sensor because only a point is scanned.

In general, a scanner is an image information input device that achieves miniaturization and low cost. In a computer unit, all figures and illustrations are expressed as dot patterns, that is, dots. Therefore, it is conceivable to photograph graphic information with a CCD (charge-coupled solid-state imaging device) camera and put the information back into a computer as a digital signal. At that time, the camera can obtain the same effect by scanning a one-dimensional image in the axial direction even if it does not represent a two-dimensional plane image like a video camera. Based on this principle, the miniaturization and low cost of the device can be realized.

Scanners are being used in various fields with industrialization. For example, a barcode scanner uses a method of scanning information on the item, transmitting the result to the main computer through the program, and then checking the result from the main computer. The patient's patient can be specified, and in the office, various documents or images can be made into various types of files that can be operated on a computer using a scanner.

There are many types of scanners used in conjunction with computers, but generally used scanners are limited to hand scanners and flatbed scanners. Hand scanners are mainly used for reading barcodes imprinted on products in places such as stores. In the era when scanners were expensive, they were used because of their relatively low price, but now they are not used very much due to resolution issues. Flatbed scanners are also referred to as flatbed scanners, and since they are easy to handle and convenient, stand-alone flatbed scanners were often used before multifunction devices became popular. In addition, since the scanner used as a component of the multifunction device is usually a flatbed scanner, it can be said that it is a kind that is still widely used in a broad sense even today, when standalone flatbed scanners are disappearing.

The operating principle of the scanner differs depending on the type of scanner, but it basically consists of a mounting point on which an object to be scanned is placed, a scanning light source, a step motor that moves the scanner head and the scanner head, and a PCB.

Types of scanners include flatbed scanners, document scanners, drum scanners, virtual drum scanners, guide scanners, barcode scanners, 3D scanners, and non-destructive scanners. Among them, flatbed scanners are general and have the advantage of being easy to handle and convenient, and they are small in volume and inexpensive in price. It has the advantage of being able to scan a variety of media such as flat manuscripts or thick manuscripts.

There are two driving methods, one that moves along the guide gear and one that uses a belt. In the case of products using the guide gear, the teeth are preformed at the time of injection, and the gear is attached to the scanning head and moves. The disadvantage is that it is vulnerable to vibrations, and it is often not possible to accurately move the position. However, it is widely used in most scanners because it is durable and operates by correcting the moving position.

As described above, in modern society, it is used in various fields and has become an indispensable technology. As such, the conventional prior art related to the scanner is a light source that emits light at a selected inclination angle in the direction of the normal of the surface of the manuscript at the position of the reading line in Korean Patent Laid-Open Publication No. 10-1994-0013109, from the light source. A document support member for guiding light to the reading line and supporting the document, a photoelectric conversion device unit for receiving light from the surface of the document, and a reflective surface for reflecting a part of light from the light source to guide the reading line. Including, and the semiannual surface is a contact type image sensor for providing a light source to at least a part of the manuscript support member disposed on a side opposite to the side of the arrangement for a read line, and the Korean Patent Laid-Open Publication No. 10 -It is manufactured in the shape of a mouthpiece in 2018-0102466, so it is easy to check the location of the teeth by scanning the shape of the patient's mouth while the patient is biting it in the mouth, so the speed of converting the shape of the tooth to data is accelerated. A mouthpiece-shaped oral scanner is disclosed, and a barcode scanner provided to read a barcode in Korean Patent Application Publication No. 10-2018-0113262 and a mobile terminal provided to output product information matched with the read barcode And a cradle provided to mount at least one of the barcode scanner and the mobile terminal, thereby providing a cradle for fixing and mounting the mobile terminal regardless of the size of the mobile terminal and combined with the barcode scanner. A barcode scanning system using a mobile terminal capable of easily performing inventory inspection and other tasks by outputting product information through a mobile terminal in wireless communication with a barcode scanner is disclosed.

However, the prior art of the prior art discloses a simple scanner in which the upper and lower scanners scan upper and lower teeth at designated positions or scan barcodes imaged on a plane.

The present invention has completed a flat and curved image scanner system that does not cause distortion by forming a plurality of lenses and sensors constituting the scanner.

The present invention is a technical configuration to solve and supplement the problems of the prior art as described above, and forms a sensor, a lens, and an LED in a set so as to scan not only a flat image but also a curved image, and the set of sensors and It is an object of the present invention to provide a flat and curved image scanner system capable of scanning not only flat images but also curved images without distortion since a plurality of lenses and LEDs are configured to scan forward or backward to match the shape of the image.

The present invention for achieving the above object is a scanner system that scans an image of a flat or curved surface, in which a glass 40 for projecting an image of the scanning line 70, which is an outer image, is located at the lowermost portion without distortion, and the glass A lens 20 to form an LED 30 that specifies and illuminates the scanning line 70 at the upper periphery of 40, and photographs an image of the scanning line 70 at the center of the LED 30 formed at the periphery. And the sensor 10, the sensor 10, the lens 20, and the LED 30, which are positioned above the lens 20, and the image of the scanning line 70 photographed by the lens 20 finally reaches. ) And a frame 50 having the glass 40 formed therein, and a main body 1 including a control unit 60 for controlling data of an image input to the sensor 10.

The sensor 10, the lens 20, the LED 30, and the glass 40 formed on the inside of the control unit 60 and the frame 50 are combined into one package, and a plurality of the one package is arranged in a row. It is made up by forming a dog.

As described above, one package consists of a frame 50 and a control unit 60, and is formed of a sensor 10, a lens 20, an LED 30, and a glass 40 inside the frame 50. .

The single package is formed in a plurality, and is formed in a line. Therefore, since the sensor 10 and the lens 20 belonging to one package only photograph a specific point in charge of each of the scanning lines 70 of the target, a uniform image can be obtained without distortion.

The control unit 60 is formed for each package or by selecting any one of forming only one control unit 60 in a plurality of packages. Further, the frame 50 is configured to be able to move up and down so that it can be closer to or away from the scanning line 70 according to the scanning line 70 of the target.

The frame 50 lifting operation is controlled by the controller 60, and the lifting operation of each frame 50 is individual according to the scanning line 70 of the target object.

In scanning the scanning line 70 of the target object using a plurality of packages as described above, if the scanning line 70 is flat, each package constituting the plurality of packages can be scanned without an elevating operation. Since the distance between the scanning line 70 and each lens 20 is the same, each package does not have an elevating operation.

However, if the scanning line 70 is curved, each package constituting a plurality of packages undergoes an elevating operation, and subsequent scanning is possible. Since the distance between the scanning line 70 and the lens 20, which is a specific point in charge of each package, is different from each other, the lifting operation is performed in each package. Since the distances between the curved scanning line 70 and each package lens 20 are all different, the frame 50 moves up and down close to or far from the scanning line 70 in accordance with the scanning line 70 to perform scanning. Because it is done, a uniform image can be obtained.

As described above, by measuring the distance between the target object's scanning line 70 and the lens 20, the frame 50 is moved closer to or farther away from the scanning line 70. ) Was uniformly scanned to obtain an accurate image, thereby completing the present invention.

The present inventors' flat and curved image scanner system has a very simple system configuration compared to conventional line scan cameras, so it is economical in maintenance and manufacturing costs, and can be installed in a smaller space than the existing scanners, so efficient space utilization is possible. , Sensors, lenses, and LEDs are configured as a plurality of scans while moving forward or backward to match the shape of the image, so that the distance between the target and the sensor to be scanned is the same and uniform image can be obtained at all locations, and a wider depth of field. It has the effect of being able to scan a clear image in the image and adjusting the scanning length, resolution, and speed according to the needs of the user.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, and in the following description of the present invention, when it is determined that detailed descriptions of related known functions or configurations may unnecessarily obscure the subject matter of the present invention. Detailed description thereof has been omitted.

In addition, terms to be described later are terms defined in consideration of functions in the present invention, which may vary according to the intention or custom of users or operators. Therefore, the definition should be made based on the contents throughout the present specification.

1 is a configuration diagram of a flat and curved image scanner system, FIG. 2 is an operation diagram of an existing scanner, and FIG. 3 is an operation diagram of a flat and curved image scanner system,

When described in detail with reference to FIG. 1,

The main body 1 is composed of a frame 50 and a control unit 60, and the frame 50 has a glass 40 that projects an image of the scanning line 70, which is an outer image, without distortion, at the bottom, An LED 30 is formed on the upper periphery of the glass 40 to specify and illuminate the scanning line 70, and a lens for photographing an image of the scanning line 70 at the center of the LED 30 formed at the periphery ( 20) is formed, and the sensor 10 is positioned above the lens 20, and the image of the scanning line 70 photographed by the lens 20 finally arrives.

Including a frame 50 in which the sensor 10, the lens 20, the LED 30, and the glass 40 are formed inside, and a control unit 60 for controlling the data of the image input to the sensor 10 It is composed of the main body (1).

The target scanning line 70 is automatically moved from left to right, and the frame 50 is fixed to scan the scanning line 70.

At this time, the LED 30 brightly illuminates the scanning line 70 to obtain a uniform and clear image, and the image of the scanning line 70 projected through the glass 40 is photographed by the lens 20, and the The image captured by the lens 20 is input to the sensor 10.

The image data input to the sensor 10 is combined and controlled by the controller 60.

As shown in FIG. 1, when the scanning line 70 is flat, the distance between the lens 20 inside the frame 50 and the scanning line 70 is the same, so that the scan is performed, but when the scanning line 70 is curved, the frame ( Since the distance between the lens 20 and the scanning line 70 inside the 50) is different, the distance between the lens 20 and the scanning line 70 must be adjusted by moving the frame 50 up and down.

In this way, if a plurality of frames 50 constituting the main body 1 are arranged in a row, each lens 20 only needs to photograph a specific point of the scanning line 70 according to the position at which the lens 20 is positioned. Then, since each lens 20 in charge of each specific point of the scanning line 70 exists, a more uniform image and an accurate image can be scanned.

That is, if a plurality of main bodies 1 are prepared and arranged side by side, a more detailed image scan can be performed. In addition, if each of the main bodies 1 is controlled separately, the height of the lifting operation is different for each main body 1 when scanning the scanning line 70 formed on the curved surface, so that accurate image scanning is possible.

The shape of the scanning line 70 formed on the curved surface and the cross-sectional shape of the lenses 20 arranged in a line are the same. The lens 20 in charge of the scanning line 70 of the convex portion takes pictures at a higher position than the lens 20 in charge of the scanning line 70 of the flat portion, and is in charge of the scanning line 70 of the concave portion. The lens 20 is to take a picture at a lower position than the lens 20 in charge of the scanning line 70 of the flat portion.

As described above, the control unit 60 controls the lifting operation of each main body 1, and the control unit 60 is formed for each main unit 1, or all main units 1 are integrated into one control unit ( It is preferable to form 60).

When described in detail with reference to FIGS. 2 and 3,

As shown in FIG. 2, since the conventional scanner comprises a lens 20 for photographing the scanning line 70 as shown in the drawing, the image of the scanning line 70 is reversed to generate unwanted distortion and input to the sensor 10. . As described above, the wider the range of the scanning line 70 is, the wider the range to be photographed by the lens 20 increases, so that the portion where distortion occurs increases. In order to correct the image in the sensor 10 that received this, the correction is performed in software or hardware.

To this end, additional cost and additional technical configuration are required, resulting in a problem that the configuration is complicated.

As shown in FIG. 3, since the present invention effectively scans all the scanning lines 70 by designating the lens 20 in charge of each point of the scanning line 70, a uniform and accurate image can be captured and input to the sensor 10. .

To this end, the main body 1 configured to enable the lifting operation is arranged side by side in a plurality of sides, and the scanning line 70 is scanned using the lens 20 and the sensor 10 belonging to each main body 1, and a curved surface When scanning the scanning line 70 of each body 1, the lens 20 belonging to each main body 1 moves up and down along the curved scanning line 70 to take a picture, so it is not a distorted input image but an accurate and uniform image. Can be obtained.

In the present invention, the above embodiments are only examples, and the present invention is not limited thereto. Anything that has substantially the same configuration as the technical idea described in the claims of the present invention and achieves the same operation and effects is included in the technical scope of the present invention.
