ようになっている。2. Description of the Related Art A multi-stage bar code label has been proposed in which a multi-stage bar code symbol is recorded on a single bar code label in addition to the one-stage bar code symbol with a limited amount of stored information. Usually, in reading the multi-stage bar code symbol, for example, the bar code symbols of all stages are picked up by an image pickup means such as a CCD camera, and each bar code symbol is sequentially read while finely scanning the image. It is like this.

FIG. 1 shows a multi-stage bar code reader according to the present invention. This multi-stage bar code reader is used for reading two-stage bar code symbols 1 and is divided into compartments in a housing 5 (see FIG. 2). 2A,
2B is provided with independent reading means 3 and 4, respectively. As shown in FIG. 2, the bar code symbol 1 of this embodiment is recorded on a card 6 such as an IC card which has a standard size and is used as a storage means for personal information.
It is designed to be inserted from the insertion opening 6A of the housing 6 which houses the multi-stage bar code reader. The bar code is not limited to such a target, and may be a bar code label attached to a box in which a product or the like is packed. Further, as a multi-stage bar code reader used in this case, a handy type bar code reader can be applied by performing positioning with a bar code by an appropriate positioning means.

て読取らせるように構成してもよい。The reading means 3 is provided in the first chamber 2A, and includes a light source 3A such as a semiconductor laser (LD) that emits light of a specific wavelength and a bar array 1A that emits the light emitted from this light source 3A.
It is composed of a mirror 3B for projecting light onto the light source and a light receiving portion 3D such as a photo sensor for forming and receiving light reflected by the barcode symbol 1A via the image forming means 3C. The reading unit 4 is provided in the second chamber 2B and has the same configuration as the reading unit 3. In this embodiment, a dedicated light source is used for each of the reading means 3 and 4, but this light source part may be shared and the light emitted from this may be split by splitting means such as a half mirror. Further, in this embodiment, the reading means of two systems is used to correspond to the two columns of bar code symbols, but the reading means having the same number n as that of n steps of bar code symbols may be provided. .
Further, in this embodiment, in order to simplify the structure, scanning is performed while moving the card 6 side on which the bar code symbol is recorded. However, the scanning means side is moved to perform scanning, or the bar code symbol is scanned. It may be configured such that each stage is imaged and read at the same time.

Since they can be read at the same time, the reading time can be greatly shortened.
