Abstract

PURPOSE:To provide a stationary scanner which can inform easily an operator of a read optimal position by providing an informing means for informing the operator of the read optimal position of the stationary scanner. CONSTITUTION:A scanner main body 20 which incorporates a scanner part is provided with a read window 21, light such as a laser light, etc., is radiated from a light source through this read window 21, and this radiated light is reflected by a barcode, and fetched through the read window 21. Also, first and second light source parts 11, 12 are provided in the vicinity of the left upper angle and the right lower angle of the surface of the scanner main body 20 to which the read window 21 is attached, respectively. This first light source part 11 radiates a first beam 31, a second light source part 12 radiates a second beam 32, and these radiated first and second beams 31, 32 intersect with each other at an intersection part. Also, a first light source part 11 and a second light source part 12 are adjusted so that the intersection part 33 comes to a read optimal position of the stationary bar-code scanner.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a stationary scanner,
In particular, it relates to a stationary barcode scanner that reads a barcode attached to a product.

[0002]

A stationary scanner is a device for reading an object to be read. As one of the stationary scanners, there is a stationary barcode scanner that reads a barcode attached to a product as an object to be read. In this stationary bar code scanner, there is an optimum reading position unique to the scanner. Therefore, when a bar code is read by the stationary bar code scanner, an operator who operates the bar code scanner needs to move the bar code to the optimum reading position and cause the stationary bar code scanner to read the bar code.

Conventionally, the optimum reading position is only shown in an instruction manual or the like. Therefore, the operator who operates the stationary bar code scanner remembers the optimum reading position while actually causing the bar code to be read.

[0004]

As described above, in the conventional stationary scanner, the optimum reading position cannot be known only by looking at the scanner. Therefore, when an operator who operates the stationary scanner for the first time or an operator who is not accustomed to the operation operates the stationary scanner, it takes time before the stationary scanner can accurately read the barcode (object to be read). was there.

SUMMARY OF THE INVENTION An object of the present invention is to provide a stationary scanner which can easily inform the operator of the optimum reading position.

[0006]

According to the present invention, in a stationary scanner for reading an object to be read, an informing means is provided for notifying an operator who operates the stationary scanner of the optimum reading position of the stationary scanner. A featured stationary scanner is obtained.

The object to be read is, for example, a bar code attached to a product.

It is preferable that the notifying means is a plurality of light source units that emit light intersecting at the optimum reading position.

[0009]

Embodiments of the present invention will be described below with reference to the drawings.

Referring to FIG. 1, a stationary scanner according to an embodiment of the present invention is a stationary bar code scanner for reading a bar code attached to a product. The stationary bar code scanner of this embodiment includes a scanner unit 10 and
It has the 1st and 2nd light source parts 11 and 12. The first and second light source units 11 and 12 are the scanner unit 10.
Is connected to the scanner unit 10. Each of the first and second light source units 11 and 12 includes a light emitting diode (LE).
D) or a lamp to irradiate light. Although the detailed configuration of the scanner unit 10 is not shown, a light source for irradiating light such as laser light, an optical unit, a photoelectric conversion unit, a decoding processing unit, which is necessary for the scanner,
It includes a data output unit and a power supply unit. The first and second light source units 11 and 12 are supplied with power from the scanner unit 10.

FIG. 2 shows the appearance of the stationary bar code scanner of this embodiment. A scanner body 20 having the scanner unit 10 shown in FIG. 1 has a reading window 21, through which light such as laser light is emitted from a light source, and the emitted light is reflected by a barcode. The emitted light is taken in through the reading window 21. In this embodiment, the first and second light source units 11 and 12 are provided near the upper left corner and the lower right corner of the surface of the scanner body 20 to which the reading window 21 is attached, respectively.

The first light source unit 11 irradiates a first light beam 31, the second light source unit 12 irradiates a second light beam 32, and these irradiated first light beam 31 and second light beam 32. And intersect at intersection 33.

The first light source unit 11 is arranged so that the intersection 33 is located at the optimum reading position of this stationary bar code scanner.
And the second light source unit 12 are adjusted. Also, visible light is selected as the first and second light rays 31 and 32 so that the intersection 33 is visible to the operator operating this stationary bar code scanner.

Although the first light source unit 11 and the second light source unit 12 are provided inside the scanner body 20 in the above embodiment, these light source units may be provided outside the scanner body 20. good. Of course, there may be two or more light source units. Further, the place where the scanner body 20 is placed or the position of the light source units 11 and 12 may be anywhere as long as an intersection is formed at the optimum reading position.
Needless to say, the object to be read is not limited to the bar code.

[0015]

As described above, since the notification means for informing the operator who operates the stationary scanner of the optimum reading position of the stationary scanner is provided, even an operator who is not accustomed to the stationary scanner can use the stationary scanner. There is an effect that an object to be read can be easily read.
