high-speed scanner

Abstract

The invention discloses a high-speed scanner, which comprises a shooting rod, wherein the shooting rod is provided with a camera lens, an accommodating cavity, an illumination light and a group of light transmission holes, the illumination light is positioned in the accommodating cavity, the group of light transmission holes is communicated with the accommodating cavity, and the transmission light rays which are emitted by the illumination light through the group of light transmission holes are irradiated onto a preset plane and are surrounded into a to-be-shot area. When the high-speed scanner is used, by presetting the positions and inclining angles of the light transmission holes, the light rays transmitted through the four light transmission holes are irradiated onto a to-be-scanned working surface, so as to form four light spots in the proper positions, the four light spots are surrounded into the clear to-be-shot area with preset size, and a user is prompted to put a to-be-scanned file on the proper area to carry out shooting type scanning operation, so the repetitive movement of the scanned file is avoided, the position of the scanned file can be accurately determined, the working efficiency is effectively improved, and better images can be obtained.

Description

technical field [0001] The invention belongs to the technical field of scanner structure design, and in particular relates to a high-speed scanner. Background technique [0002] Scanner is a kind of external computer equipment. By capturing images and converting them into digital devices that can be displayed, edited, stored and output by computers, traditional scanners used in work are generally large in size and inconvenient to carry. It can cause a lot of hassle when technical data needs to be scanned. [0003] In order to adapt to the needs of the market, there are existing photographic scanners (commonly known as high-speed cameras) on the market. When in use, use its base to stand next to the computer to perform photographic scanning. When this kind of photographic scanner is in use, due to the lack of positioning marks for locating the piece to be scanned that traditional scanners have, in actual use, in order to obtain a better image, it is often necessary to adjust...

AI Technical Summary

Problems solved by technology

When this kind of photographic scanner is in use, due to the lack of positioning marks for locating the piece to be scanned that traditional scanners have, in actual use, in order to obtain a better image, it is often necessary to adjust the piece to be scanned by hand many times to make it In place, its operation is time-consuming and laborious, and even then, it is often difficult to obtain a satisfactory scanned image
