Abstract

PURPOSE:To easily position a bar code reader and to improve the reading operability of the reader by providing a filter mirror on the upper surface of an opening part of the bar code reader to reflect the near infrared rays. CONSTITUTION:The bar code images of near infrared rays are reflected by a filter mirror 12 for reflection of near infrared rays. The bar code images formed by the peripheral external light (visible light) pass through the mirror 12. Thus the bar codes 6 set under an opening part can be viewed through via the mirror 12 of a bar code reader 11. As a result, the reader 11 can be easily positioned to the codes 6 and the reading operability is improved with the reader 11 since the codes 6 set under the opening part are not hidden by the reader 11 and can be viewed through.

Description

【発明の詳細な説明】 Ｃ産業上の利用分野〕 本発明はバーコード読取装置に係り、ＰＯ３シ、ステム
に好適なハンドベルトタイプのスキャナに関する。DETAILED DESCRIPTION OF THE INVENTION C. Industrial Application Field The present invention relates to a barcode reading device, and relates to a hand belt type scanner suitable for a PO3 system and stem.

ラーにすることにより、達成される。An object of the present invention is to facilitate the positioning of the barcode reader and improve reading operability. This can be achieved by making the upper surface of the opening of the barcode reader a filter mirror for reflecting near infrared rays so that the stored barcode can be seen through.

下のバーコードを透視することができる。The optical system of the barcode reader functions with near-infrared rays, but since a filter mirror for reflecting near-infrared rays is used as a reflecting mirror, there is no loss of optical energy for driving a one-dimensional image sensor such as a CCD. Also, since most of the visible light passes through the filter-mirror, it is possible to see through the barcode under the aperture.

〔実施例〕〔Example〕

以下、本発明の実施例を第１図により説明する。 Embodiments of the present invention will be described below with reference to FIG.

サ５に集光されバーコードを読みとるものである。Although Figure 2 is a conventional example, in the present invention, a filter baller 12 is used in place of the total reflection mirror 2. The reading mechanism of the barcode reader is that near-infrared light emitted by an LED 7 creates a barcode image by a barcode label 6, is reflected by a reflector 2 or 12, and is reflected by a lens 5,
The light is focused on a one-dimensional image sensor 5 such as a COD via a red filter 4, and a bar code is read.

る。According to this embodiment, the filter mirror 1 for near-infrared reflection
2 reflects the near-infrared barcode image, but the barcode image due to surrounding external light (visible light) is transmitted through the filter mirror 12. You can see through the code. Therefore, according to this embodiment, since the barcode under the opening can be seen through, the barcode reader can be easily positioned with respect to the reduced barcode, which improves the barcode reading operability. effective.

操作性の向上に効果がある。According to the present invention, since the barcode under the opening of the barcode reader can be seen through without being hidden by the barcode reader, the barcode reader can be easily positioned with respect to the barcode, and the barcode can be seen through the opening of the barcode reader. This is effective in improving readability.
