学的に読み取る光学読取装置が存する。2. Description of the Related Art Conventionally, as shown in FIG. There are optical reading devices that optically read data such as codes.
発明が解決しようとする問題点
しかし、発光部から多方向に走査される走査謎24.2
5,26.27は、商品23の下面及び側面までは照射
されても商品23の上面までは照射されない。したがっ

る。Problems to be Solved by the Invention However, the scanning puzzle of scanning in multiple directions from the light emitting part 24.2
5, 26, and 27, although the bottom and side surfaces of the product 23 are irradiated, the top surface of the product 23 is not irradiated. Therefore, if the barcode is facing upward, it is unreadable.
問題点を解決するための手段
発光部及び光の明暗を検出する光電変換部が内蔵された
筐体の上面に透光窓を設け、前記透光窓を透過した前記
発光部からの光線を前記透光窓に反射する反射面をこの
透光窓の上部空間に位置させて設ける。Means for Solving the Problem A light-transmitting window is provided on the top surface of a housing in which a light-emitting part and a photoelectric conversion part for detecting the brightness of light are built in, and the light rays from the light-emitting part that have passed through the light-transmitting window are A reflective surface that reflects light on the light-transmitting window is provided in a space above the light-transmitting window.
作用
したがって、発光部からの光線は透光窓を透過して上向
きに照射されるだけでなく、この上向きの光線が反射面
に反射するため透光窓に向かう光線が得られ、上向きの
光線も下向きの光線も商品の側面まで照射させることが

能となる。Effect: Therefore, the light rays from the light emitting part not only pass through the light-transmitting window and are irradiated upwards, but also the upward light rays are reflected on the reflective surface, resulting in light rays directed toward the light-transmitting window. It is also possible to irradiate the sides of the product with downward light. Therefore, when a product is passed between the translucent window and the reflective surface, it is possible to read data on any surface.

ラー群とよりなるが、型式が限定されるものではない。Embodiment An embodiment of the present invention will be explained based on FIG. Reference numeral 1 denotes a housing, and the housing 1 includes a light emitting section (not shown) and a photoelectric conversion section (not shown). The light emitting part is
For example, it includes a polygon mirror, a hologram disk, a galvano mirror, etc. that scans a laser beam, and a group of mirrors that converts the scanning line into a dynamic pattern, lattice pattern, etc., but the type is not limited.

A side wall 3 that extends upward from the end of the transparent window 2 and a ceiling surface 4 that slopes slightly upward toward the tip are continuously formed, and these side walls 3 and the ceiling surface 4 have reflective surfaces. Mirrors 5 and 6 are fixed.
二のような構成において、発光部からは多方向に走査線
7,8,9.10が上向きに照射される。In configuration 2, scanning lines 7, 8, 9, and 10 are emitted upward from the light emitting section in multiple directions.

ーはこの実施例のように二枚に限られるものではなく、
−枚でも二枚以上でも良いものである。Now, if we take a specific scanning line 9 and look at its reflection state, the scanning line 9 irradiated upward from the transparent window 2 is reflected while being diffused by the mirror 5, and is further diffused and transmitted by the mirror 6. The light is reflected toward the light window 2. Looking at other scanning lines, the direction of the light rays varies depending on the scanning angle as they are reflected by the mirror 5 or 6. Therefore, product 1
When reading the barcode No. 1, no matter which direction the barcode is facing, the barcode is irradiated with a beam of light, and the reflected light of the barcode is reflected by one or both of the mirrors 5 and 6 and directed toward the photoelectric conversion section. This allows product 1 to be reflected.
1 data can be read reliably. In addition, transparent window 2
The number of mirrors that reflect the scanning lines scanned from the mirror toward the transparent window 2 is not limited to two as in this embodiment.
- or two or more sheets.

も読み取ることができる効果を有する。Effects of the Invention Since the present invention is constructed as described above, the light rays from the light emitting part not only pass through the transparent window and are irradiated upward;
Since this upward light ray is reflected by the reflective surface, a light ray directed toward the transparent window is obtained, and both the upward and downward light rays can be irradiated to the side of the product. It has the effect of being able to read the data on any side when passing the product between them.
