Description

A book scanning device having a uniform illumination unit and a vertically combined total reflection mirror The present invention relates to a device for scanning books using a smartphone, and more specifically, to a book scanning device comprising a uniform lighting unit and a vertically coupled total reflection mirror, wherein a book is mounted on an acrylic plate forming a certain angle to prevent curvature, an LED light is indirectly illuminated toward the acrylic side to create a uniform lighting environment, and the contents of the book transmitted by the light are transmitted through a reflector made of a total reflection mirror provided at the bottom, thereby enabling scanning using a smartphone. Generally, when scanning books, a scanner is used, but since it is scanned in a flat form, the folds of the book cause curvature, resulting in a problem where the scan quality is degraded. Recently, various applications that allow scanning documents using smartphones are being used, making it easy to scan documents without using a scanner. However, even when scanning with a smartphone, distortion occurs due to the curved parts of the book and must be corrected; even after correction, the scan quality varies depending on the degree of curvature, and a problem arises where the scan quality deteriorates compared to scanning standard flat documents. In addition, if fingers holding the open book are captured along with the image and subsequently corrected, a problem arises where the scan quality deteriorates. In addition, problems arise where a uniform scanning state cannot be maintained depending on the location and intensity of fluorescent lights inside the office, such as during the day, as strong light enters from bright windows or when the interior is dark. In this regard, prior art document 1 (Registered Patent 10-1888126, Book Scanning Device Using a Smartphone) discloses a configuration in which a book to be scanned is placed between a V-shaped pressing plate and a book holder, and a smartphone camera is placed in a hole of the cover part so that the book can be scanned without a separate scanning device. However, prior art 1 scans the book directly using a smartphone while it is fixed in a V-shape, so the quality is degraded due to the slanted surface that occurs when it is fixed in a V-shape, or it is difficult to scan in a flat shape. FIG. 1 is an overall perspective view of a book scanning device having a uniform illumination unit and a vertically coupled total reflection mirror according to an embodiment of the present invention. FIG. 2 is an exploded perspective view of a book scanning device having a uniform illumination unit and a vertically coupled total reflection mirror according to an embodiment of the present invention. FIG. 3 is a usage state diagram illustrating a state in which a smartphone is mounted on a book scanning device equipped with a uniform illumination unit and a vertically coupled total reflection mirror according to an embodiment of the present invention and scanned.

FIG. 9 is an operation state diagram of a smartphone position adjustment unit in a book scanning device equipped with a uniform illumination unit and a vertically coupled total reflection mirror according to a second embodiment of the present invention. The present invention relates to a device capable of scanning a book using a smartphone camera, and is characterized in that it can scan the image of a book with high quality without inversion by using a reflector composed of at least one total reflection mirror that is vertically coupled to uniformly and stably irradiate light while the book is mounted at an angle so as not to create a curved surface on the book. Hereinafter, a book scanning device having a uniform illumination unit and a vertically coupled total reflection mirror according to an embodiment of the present invention will be described in detail with reference to th
