Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handy scanner for reading a bar code, and more specifically, a laser beam reflected by a laser beam emitted from a projecting section for reflecting the laser beam on the bar code. The present invention relates to a handy scanner provided with a light reflection section.

[0002]

2. Description of the Related Art In recent years, POS systems (POS are poin
There are various types of bar code readers used in business processing systems such as t of sales). Among them, especially handy type bar code readers, due to their good operability, etc. Instead of the light pen type described above, a so-called laser scanner integrated type handy scanner is generally used.

This handheld scanner integrated with a laser scanner has a light emitting element for emitting a laser beam and a light receiving element for receiving the reflected light as main components, which is similar to the light pen type. In addition to the above components, this type of handy scanner scans the laser beam emitted from the light emitting element in the longitudinal direction of the bar code in response to the pressing of the reading switch provided on the main body. A laser scanner is provided which allows the light receiving element to receive the reflected light. That is, according to this handy scanner, the reading is automatically performed by simply irradiating the barcode with the laser light without moving the barcode while making contact with the barcode unlike the conventional light pen type.

Therefore, the laser light emitting element provided in the laser scanner main body is directed to the bar code, the laser beam is emitted, and the reflected light reflected from the bar code is received by the light receiving portion, whereby the bar code of the bar code is detected. Reading is taking place.

[0005]

By the way, a bar code may be attached to the side surface of an H steel material or the like of a building steel material. Since this H steel material is a heavy object that cannot be easily moved by human power, for example, a plurality of H steel materials are arranged at such a narrow interval that the light emitting part of the handy scanner cannot be inserted between adjacent H steel materials. Then, of course, it was not possible to irradiate this bar code with laser light. In such a case, since it is impossible to read with a handy scanner, it is necessary to write the numbers of the barcode by handwriting instead of reading the barcode.

As described above, depending on the product, there is a problem that the handy scanner cannot be used even if the bar code is attached. The present invention has been made on the basis of such an actual situation, and an object thereof is to provide a light reflecting portion capable of irradiating a bar code which cannot be radiated with a laser beam with an existing handy scanner. It is to provide a handy scanner.

[0007]

The present invention emits a laser beam for reading a bar code, and the emitted laser beam is reflected after being irradiated on a bar code display surface,
In a handy scanner having a laser beam emitting / receiving unit for receiving and reading the reflected laser beam, a light reflecting unit for reflecting the laser beam emitted from the laser beam emitting / receiving unit in an arbitrary direction is rotated. The handy scanner has a holder that is connected to one end of a shaft body that supports the light reflecting portion so that the holder is detachably attached to the main body of the handy scanner at the other end side of the shaft body. The laser light emitted from the laser light emitting / receiving unit is applied to the bar code label via the light reflecting unit, and the laser light reflected from the bar code label is emitted / receiving the laser light via the light reflecting unit again. Provided is a handy scanner including a light reflecting member, which is capable of receiving light.

[0008]

The handy scanner equipped with the light reflecting member of the present invention is rotated at an arbitrary angle so that the laser light emitted from the laser light emitting / receiving portion of the handy scanner can be accurately applied to the display surface of the bar code. Equipped with a movable light reflector,
The light reflecting portion reflects the laser light and irradiates the barcode. Then, the laser beam applied to this bar code is reflected from the bar code, reflected again by the light reflecting section, and received by the laser beam emitting / receiving section of the handy scanner.

With the handy scanner of the present invention, it becomes possible to irradiate a laser beam on a bar code provided at a position where the laser beam could not be radiated so far.

The use of the handy scanner 1 will be described. For example, as shown in FIG. 3, a plurality of steel materials 9 of a building steel frame material are arranged in an interval in which the main body of the handy scanner 1 cannot be inserted. It is placed.
A bar code 10 is provided on the side surface of the steel material 9,
When reading the bar code 10, first, the reflecting portion 4 rotatably connected to the one end portion 5a of the support shaft 5 of the light reflecting member 3 provided in the handy scanner 1 is connected to the laser light emitting / receiving portion 2a. Is set to a predetermined angle.

Then, by pressing a reading switch (not shown) provided in the handy scanner body 2, the laser beam 11 is emitted from the laser beam emitting / receiving section 2a.
The laser light 11 strikes the reflecting portion 4 which is set in advance at a predetermined angle so as to irradiate the above-mentioned bar code, is reflected, and is radiated to the bar code 10.

Subsequently, after the laser beam 11 is applied to the bar code 10, the laser beam 11 is reflected from the bar code 10. Then, the reflected laser light 11 is reflected again by the reflecting portion 4, and the laser light 11 emits laser light /
It is incident on the light receiving portion 2a.

Then, the laser light emitting / light receiving portion 2a receives the laser light 11 and the bar code 10 is read. Therefore, even if there is a gap in which the handy scanner cannot be inserted, the reflecting portion 4 connected to the support shaft 5 can be inserted into the gap, so that the barcode is provided at a position sandwiched in a narrow space. Can also read it.

The arm portion 8 forming the fixed frame body 6 may be formed in a shape symmetrical to the shape shown in FIG. 1 so that it can be mounted from the side surface on the opposite side of the handy scanner body 2. .

The handy scanner body 2 not used
