In the merchandise sales registration apparatus 1 exemplified as the first conventional example, actually, the emission position of the scanning light is only displayed on the plane, and the optical axis of the scanning light is displayed. The sweet spot located is indistinguishable.

In the bar code scanner 6 exemplified as the second conventional example, since the hologram sheet and the dedicated spotlight 8 are required, the structure of the system is complicated and the conditions such as normal illumination tend to be limited. Since the visibility is low, the work load of the cashier tends to increase.

In the commodity sales registration device 10 exemplified as the third conventional example, there is a concern that the wire 14 may be deformed due to aging and the like, and the cashier repeatedly collides his or her fingers with the wire 14 during work. Therefore, it is not preferable.

The above-mentioned various devices 1, 6, 10
However, since the scanning direction cannot be specified even if the position of the sweet spot of the scanning light is specified, the bar code reading accuracy is deteriorated and the work load on the cashier is increased.

[0013]

A bar code scanner in which a sweet spot of scanning light is set at a bar code reading position, and an imaging device in which a focus position is set in the sweet spot of scanning light of the bar code scanner is provided. A monitor device for displaying an image captured by the image pickup device is provided, and position indicating means for displaying an index indicating the position of the sweet spot of the barcode scanner is provided on the display surface of the monitor device.

[0014]

A bar code scanner is provided with an image pickup device in which a focal position is set to a sweet spot of scanning light of a bar code scanner, and a monitor device for displaying an image photographed by the image pick up device is provided. By providing the position indicating means for displaying the index indicating the position of the sweet spot, the image of the barcode located on the reading window of the barcode scanner is displayed on the display surface of the monitor device. It is possible to position the bar code on the sweet spot of the scanning light by moving the bar code so that the display image is well formed at the position corresponding to the index.

[0015]
