実施例 この発明の第一の実施例を第１図に基づいて説明する。Example A first embodiment of this invention will be described based on FIG.
片手で把持する本体１の前ｆｌａ＋に反射面２が配置さ
れ、中間部に集光レンズ３が配置され、後部にＣＯＤ等
の受光素子４が配置されている。A reflective surface 2 is arranged on the front fla+ of the main body 1 which is held with one hand, a condenser lens 3 is arranged in the middle part, and a light receiving element 4 such as a COD is arranged in the rear part.
また、本体の前部下面には読取窓５が形成され、前部上
面にフィルタ６を度合した外光入光窓７が形成されてい
る。このフィルタ６は６３０ないし７００ナノメータの
波長の光を通すものである。Further, a reading window 5 is formed on the front lower surface of the main body, and an external light entrance window 7 with a filter 6 is formed on the front upper surface. This filter 6 passes light having a wavelength of 630 to 700 nanometers.
このような構成において、読取窓５に対向するラベル８

いは太陽光線等の外光を照射し、ラベル８からの反射光
を反射面２により反射し、集光レンズ３により集光して
受光素子４に入光する。受光素子４の出力は外部回路に
入力されて例えばバーコードが読み取られる。In such a configuration, the label 8 facing the reading window 5
The recording surface of the label 8 is irradiated with external light such as indoor illumination light or sunlight that has entered through the external light entrance window 7, and the reflected light from the label 8 is reflected by the reflective surface 2 and condensed by the condensing lens 3. The light is emitted and enters the light receiving element 4. The output of the light receiving element 4 is input to an external circuit and, for example, a bar code is read.
このように、ラベル８は外光により照明されるため、光
源を省略し消費電力を大幅に節減することができる。こ

化が可能で、使用場所が限定されることがなく、取扱性
が極めて向上する。In this way, since the label 8 is illuminated by external light, a light source can be omitted and power consumption can be significantly reduced. Accordingly, a power cord for supplying power to the light source can be omitted. The output of the light receiving element 4 can also be outputted to an external circuit by radio waves. Therefore, it can be made cordless, there are no restrictions on where it can be used, and the ease of handling is greatly improved.
また、バーコードは小さくなる傾向にあるが、外光入光
窓７からバーコードを見ることができるため、読取窓５

ができる。さらに、フィルタ６により画像照明に悪影響
を与える波長の外光の入光を制限することができる。Also, although barcodes tend to be smaller, barcodes can be seen through the outside light entrance window 7, so the reading window 5
You can quickly move the barcode directly above the barcode. Furthermore, the filter 6 can restrict the entry of external light having a wavelength that adversely affects image illumination.

、回路の判断を待つまでもない。The color of the barcode is specified by the JIS standard, and barcodes other than the standard cannot be read by the light receiving element 4. In this case, the contents of the label 8, that is, the contents of the product, can be read with the human eye and registered. Register using the key. When the barcode is successfully read, an electronic buzzer (not shown) sounds, but the reason why the barcode cannot be read is not only due to the color of the barcode, but also because the position of the reading window 5 is misaligned, and it may take some time for the electronic buzzer to sound. be. Even during this time, if the color of the barcode is out of the standard, the user can immediately visually recognize that the color is out of the standard without waiting for the electronic buzzer to sound. That is, when the color of the vanicode is red, red external light illuminates the barcode through the filter 6, making it impossible to visually read the barcode even when viewed from the external light entrance window 7. Therefore, there is no need to wait for the judgment of the circuit.
さらに、反射面２は外光入光窓７がら読取窓５に向かう
外光が当らないのでラベル８上に影を落すことがなく、
また、ラベル８の画像情報以外の光情報を受光素子４に
反射することもない。Furthermore, since the reflective surface 2 does not receive external light directed toward the reading window 5 from the external light input window 7, it does not cast a shadow on the label 8.
Further, optical information other than the image information of the label 8 is not reflected to the light receiving element 4.

を有する。Effects of the Invention As described above, this invention forms an external light entry window in the main body, thereby omitting the light source for illuminating the image, making it possible to go cordless, and thus significantly reducing power consumption. In addition, by locating the outside light entry window so that outside light does not hit the reflective surface, it prevents the reflective surface from casting a shadow on the image and improves the light reception. It is possible to eliminate the influence of external light on the element,
Furthermore, by installing a filter on the outside light entrance window, we can prevent the entrance of outside light with wavelengths that have a negative effect on image illumination.
It is also possible to visually recognize the reading of images with non-standard colors, and by installing a condenser lens in the outside light input window, it is possible to efficiently use outside light for image illumination. Furthermore, by providing a light shielding plate with an opening formed between the reflective surface and the light receiving element,
This has effects such as being able to eliminate the influence of external light on the light receiving element.
