Description

Currently, the mouse is used as a pointing device for computer operations.

Currently, personal computers are used for homepage browsing and spreadsheets by using input devices such as a mouse and keyboard. The use of Internet browsing software has become active due to the spread of broadband Internet. In the promotion of the URL of the HP, the URL for a personal computer is printed and introduced in a newspaper, an advertisement, a free paper, a flyer, or a catalog.
As a mouse, an optical mouse in which an LED and an image sensor are arranged in a V or letter shape is widespread. However, there is a case where an erroneous reading of a mouse position occurs due to the quality of a mouse pad or a desk. In order to solve this problem, a mouse that can detect a mouse position with high accuracy using a transflective lens has been commercialized.

Currently, with the spread of the Internet, advertising using a URL reading function using a camera function by printing a QR code on a printed matter targeting mobile phone users is being carried out. However, in the case of a personal computer, reading of QR codes is not widespread because cameras are not standard equipment on all personal computers. Therefore, the personal computer user inputs a long URL alphanumeric character from the keyboard into the URL input field of the HP browsing software. In the case of a long URL, there are many cases where the HP is not displayed correctly or another HP is displayed due to a mistaken type, and the built-in camera is quickly and accurately displayed like a QR code as in the case of a mobile phone. Cannot work on.
In addition, the QR code of the mobile phone has a square shape, and the layout of printed articles such as newspaper articles, magazines, and advertisements requires a large space from the viewpoint of the placement space. In order to lay out the QR code on a printed matter, a large advertisement frame, article frame, and paper space are occupied.
However, it can be said that the one-dimensional barcode that is widely used as a label for product management has a relatively high degree of freedom in layout because of its horizontally long shape. In addition, USB-compatible handheld barcode readers for POS for reading one-dimensional barcode labels for personal computers have been commercialized. However, because it employs a high-definition CCD array of laser diodes and line sensors aimed at high-speed scanning for business use, it is expensive and bulky. It is not popular in ordinary homes and offices. For this reason, the PC user has a hard time inputting the URL of the printed matter from the keyboard.
However, even if the LED, image sensor, and reflector are designed at the tip of the mouse for barcode scanning at the reading part at a specific position within the tip of the mouse, the position of the wheel, which is an essential function of the mouse as shown in FIG. However, it cannot be designed at the tip / center of the mouse, making natural wheel operation difficult and hindering the function of the pointing device. Furthermore, the tip of the mouse becomes larger as shown in Fig. 5. Even if it is designed to have a sharp shape, it is not easy to scan a high-definition barcode horizontally and accurately with high accuracy. It is difficult to read errors due to tilt or protrusion.
Furthermore, the bar code surface is focused and irradiated at an acute angle 18 where the optical axis of the LED is almost horizontal, and there is also a paper quality relationship and compatibility, and the risk of erroneous barcode reading increases due to the angle of light collection. Even when used as a pointing device, the accuracy may be reduced due to erroneous reading depending on the compatibility of the surface quality of the desk or mouse pad. Since the image sensor and the LED are arranged vertically on the horizontal plane, there is a risk of hindering accurate mouse position detection due to light collection even when a reflector is used. Mouse is not commercialized.

移動量・移動方向のデータ処理をすると共に、バーコード読取時には一次元バーコードをマウスの先端でなぞりスキャンする事により印刷物の一次元バーコードのＵＲＬをスピーディに正確に読み取るものです。
従来の半透過・反射レンズを使用しない光学式マウスの場合は、マウス先端部に読取部を配する関係からＬＥＤと撮像素子とレンズを全てマウス先端部へのデザインが必要となり、これを受けホイールが極めて操作しづらいマウス中央部へ押しやられます。更に鋭角な角度でＬＥＤ光がバーコードへ照射される事より、例え反射板にて反射光を垂直に反射させたとしてもマウスの位置検出精度・バーコードの読取精度に限界があります。更に目視でマウスを細かいバーコード上をガイドに沿って正確になぞり・スキャンする事は困難で、誤読取の原因となります。
従いデータ処理ソフトと半透過・反射式光学レンズと反射板とＲＡＭメモリーと押しボタンの追加が必要なるも、マウス用の基幹電子部品のマイナーチェンジにより高精細なバーコードデータの取り込みを行い、マウスのコスト力を継承し、パソコン用周辺機器として高速高精細ラインスキャンＣＣＤを採用した手持ち式バーコードリーダーに比べ圧倒的な普及価格での商品化が可能な位置付けの商品です。The mouse has been used as a set as a pointer on a personal computer as an essential item for browsing the Internet and operating basic software. In addition, a large number of mice that support an interface such as USB are sold as an option at a popular price.
The present invention divides the light of the LED light source for mouse position detection placed in front of the mouse into two rays through a transflective optical lens, one of which is led to the tip of the mouse and installed at the tip of the mouse The one-dimensional bar code reading unit reflects the light downward with a reflecting plate, irradiates the light on the bar code, and the reflected light is received by the central high-performance image sensor via the transflective optical lens. Then, the image is detected, and on the other hand, the movement amount / direction information of the mouse is detected, and the URL code of the one-dimensional barcode is read by linking this with the processing of the barcode reading signal. Move the mouse horizontally by hand, scan the barcode along the reading part at the tip of the mouse, and convert the URL into text data by the above data processing.
The protruding portion of the reading portion at the tip of the mouse is small and low, and a small bar code can be scanned in the horizontal direction relatively easily with the aiming guide for scanning by hand.
This makes it possible to paste the URL information of the one-dimensional barcode on the URL input frame of the Internet browsing software of the personal computer. At the same time, it is possible to design the wheel, which is an essential function of the mouse, at a position where the center and tip of the mouse can be operated easily. Tilt-compatible wheel can be operated with natural index finger operation.
The image sensor reads changes in image position information on the desk with light to detect the position of the mouse. By scanning the barcode with the barcode reader of the mouse, the barcode data is scanned and the URL data is imported.
The amount and direction of movement of this read information is linked to the barcode information, the bar code reading unit recognizes the image of the length of the bar signal, processes this image information, stores it in the buffer memory, and stores the barcode. The image is completed and converted to text data. If a reading error occurs due to an error detection code installed at the end of the bar code of the URL, the user is notified by the two-color LED of the wheel.
Based on the current normal optical mouse, with the addition of an optical lens for bar code reading, a transflective optical lens, a push button to the side of the mouse, RAM memory, and a transflective lens

In addition to processing the amount of movement and the direction of movement, scanning the one-dimensional barcode with the tip of the mouse when scanning a barcode speedily and accurately reads the URL of the printed one-dimensional barcode.
In the case of an optical mouse that does not use a conventional semi-transmissive / reflective lens, it is necessary to design the LED, image sensor, and lens all at the tip of the mouse because of the arrangement of the reading part at the tip of the mouse. Is pushed to the center of the mouse, which is extremely difficult to operate. Furthermore, the LED light is irradiated onto the barcode at an acute angle, so even if the reflected light is reflected vertically by the reflector, the mouse position detection accuracy and barcode reading accuracy are limited. Furthermore, it is difficult to accurately trace and scan the mouse along the guide with a fine bar code visually, which may cause misreading.
Therefore, it is necessary to add data processing software, transflective / reflective optical lenses, reflectors, RAM memory and push buttons, but high-resolution bar code data is captured by minor changes to the key electronic components for the mouse. It is a product that can be commercialized at an overwhelmingly popular price compared to a hand-held barcode reader that inherits cost power and uses a high-speed, high-definition line scan CCD as a PC peripheral.

In addition to the function of a mouse with a wheel as a conventional pointer, the present invention wirelessly transmits the URL of the HP accurately by manually tracing a one-dimensional bar code such as a newspaper with a bar code reader placed at the tip of the mouse. Import into the mouse body ・ Select the URL input frame of the Internet browsing software and operate the paste button on the side of the mouse to store up to 10 URLs in the mouse that supports wireless communication ・ Via the USB wireless communication receiver A mouse that can be pasted into the URL input frame of the Internet browsing software on the PC.
The mouse is based on an optical mouse that adopts the current transflective optical lens compatible with the current USB interface, and is based on a simple basic circuit and mechanism configuration by modifying the above hardware and software. As a peripheral device that can be inserted into the USB slot of most personal computers that are now widely used in society, it is expected that USB mice will be replaced and spread.
This mouse uses a semi-transmissive / reflective optical lens to reflect and transmit light vertically, and the LED is placed in front of the mouse and the image sensor is placed in the middle of the mouse. By tracing the bar code along the guide of the protruding part of the part, it is possible to easily read the data of the bar code, and the vertical scroll wheel can be placed at a position where it can be operated with a natural finger position.
In addition to the mouse function as a pointer with vertical and horizontal scrolling functions, it can also read one-dimensional barcodes that are intentionally printed on newspapers, free papers, catalogs, brochures, and flyers. It features what is possible.
For newspapers, magazines, and free papers, the feature is that up to 10 URLs in total can be stored in the RAM of the mouse body using a battery, and arbitrary URLs can be pasted by button operation. This frees the user from the troublesome URL input from the keyboard, and enables quick and accurate display of the URL information of the printed matter on a personal computer like a QR code.
Adopting a transflective optical lens, it transmits and reflects light at 90 degrees, and has the ability to read the position of a mouse and a high-definition barcode with extremely high accuracy. As a barcode, horizontal and long codes can be captured and processed by the image sensor of an image sensor with extremely high image reading accuracy, and in addition to information as a mouse pointing device, barcode information It is possible to accurately paste, store, and paste in the URL input field of the Internet browsing software.
In a conventional optical mouse, the light source and the image sensor are arranged in a V or letter shape, and variations in accuracy occur due to the quality of the mouse pad or desk. Even if a reflector is added to this system and the barcode is changed to a design that can be read, the reading quality and detection accuracy of the mouse position may vary due to the paper quality of the barcode, and misreading may occur. Even if a reflector is placed at the tip of the mouse, the image sensor and LED need to be designed at the tip of the mouse, so that the wheel position is pushed to the center of the mouse as shown in FIG. A problem occurs. In addition, since it is difficult to grasp the guidelines for reading barcodes, there is a limit to accurate scanning and reading of narrow barcodes.

Fig. 3 shows the best mode for realizing the present invention. The appearance of this mouse is the same as that of a normal mouse, but a reading reflector for reading one-dimensional barcodes is provided at the tip of the mouse, and a transflective optical lens is placed at the center of the mouse. . By scanning the one-dimensional barcode in the reading unit, the barcode information of the URL is taken into the memory using the image sensor for the mouse, converted into text information, and taken into the personal computer via the USB interface with the wireless communication function. . On a personal computer, URL information captured in the URL entry field of the Internet browsing software is pasted with the button on the side of the mouse, and the HP of the URL of the printed matter is accurately displayed.

Fig. 3 shows a specific example of a mouse. The mouse of the present invention uses a normal optical mouse imaging device to read a one-dimensional barcode with a mouse that has a barcode reading reflector at the tip and a transflective optical lens at the center of the mouse. This is a mouse that can capture the URL URL image, code conversion, and import to the PC by tracing the part.

The device will be explained with the external view of the side of the mouse. The device will be explained using the external view on the top of the mouse. The device will be explained with a cross-sectional view from the side of the mouse. The device will be explained with the flow chart of mouse barcode data import. Describes the design specifications that indicate the wheel position when a barcode reading function is added to the tip of a conventional optical mouse.
