Description

[Detailed Description of the Invention] The present invention relates to an improvement of the operation unit mechanism in an optical reading device such as a fixed scanner used in a POS terminal.

Fixed scanners are optical reading devices used in POS systems that automatically read product codes (hereinafter referred to as barcode symbols).

In this conventional optical reading device, as shown in a perspective view in FIG. 1, a main body 1 includes a reading section 2, an operating section 3,
A product 6, which is composed of a display section 4, an optical unit, a power supply, etc., and has a barcode symbol 5 moves in a product scanning direction a indicated by a white arrow through a product passageway that is above the reading section 2 on a fixed scanner surface 2-1. In the process, a laser beam b is emitted from the reading section 2 in the direction of the white arrow from the optical unit built into the main body 1 of the fixed scanner and automatically reads the information on the barcode symbol 5 of the product 6. . Further, when desired information is input by operating the keyboard of the operation section 3, the product contents, total amount, etc. are displayed on the display section 4 based on the information.

By the way, in the conventional operation unit 3, as shown in the side view in FIG. 2a, the operating angle of the operator is fixed and the angle θ
Since this is constant, the operability is hindered by differences in operator height, etc. In addition, as shown in the side view in FIG. 2b, depending on the reading medium width A of the product 6, the downward inclination angle of the operation unit 4 hits the product passage path, and the medium width A within the range of that angle is restricted. It has the following disadvantages.

The present invention aims to eliminate the above-mentioned drawbacks.The purpose of the present invention is to provide a rotating shaft at the top of the left and right sides of the operating section, and a screw hole for the tilting operation knob at least on the side near the bottom. This is achieved by providing slide grooves in the portions of the left and right support members that correspond to the screw holes.

At this time, the lower part of the operation part can be adjusted back and forth with the product passageway in front, and the degree of inclination of the operation part can be fixed at a position convenient for the operator. It also becomes possible to expand the width of the passage.

An embodiment of the operating section mechanism in the optical reading device according to the present invention will be described below with reference to FIGS. 3 and 4. FIG. 3a is a perspective view showing the optical reading device according to the present invention, b is a perspective view showing the main parts of the operating section, FIG. 4a is a side view showing the operating angle of the operator, and FIG. FIG. 3 is a side view showing the media width. The same reference numerals indicate the same objects throughout the figures.

In the figure, 7 is the rotation axis of the operation unit 3,
It is supported by the support member 8 and connected to the upper end of the operating section 3 so that the operating angle can be pivoted. The support member 8 has a slide groove 9 below and is fixed to the rear upper part of the main body 1. Reference numeral 10 denotes an operating knob, which is screwed and fixed to the lower part of the operating section 3 via a slide groove 9.

As shown in FIG. 4a, in order to set the operating angle to an arbitrary angle due to the operability due to differences in operator height, etc., first loosen the screw on the operating knob 10. By moving the operating portion 3 in the direction of the arrow through the slide groove 9 about the rotational fulcrum 7 to correspond to the operator, and tightening the screw of the operating knob 10, the optimum operating position for the operator can be obtained. Moreover, when the size of the product 6 is large as shown in the reading medium width B in FIG. It is now possible to use a reading medium with a width of B.

As explained above with reference to the embodiments, in the rotating mechanism of the operating unit according to the present invention, the operating angle that is easy for the operator to operate can be obtained by the structure having the rotating shaft that changes the operating angle at the upper part of the operating unit. ,and,
The variable amount of the movement range of the operation angle can correspond to the width of the product size, and the practical effects are great, such as ease of operation.
