Description

[Detailed description of the invention] The present invention relates to a unit price setting device for a label printer.

Conventionally, the unit price setting device for this type of label printer has a unit price setting board in which the unit price corresponding to the product name stamp is displayed with a hole in the product name stamp housing provided with the product name stamp, and mechanical detection using a switch is performed through this hole. Alternatively, the unit price was read using photoelectric detection using an LED and used as data for display and printing.

However, in such a configuration, the unit price data is directly displayed on the unit price setting board, which makes the structure complicated and limits the number of data types.In addition, when prices have fluctuated rapidly, as has been the case recently, the setting board is updated each time. The holes had to be repaired using the Ming method, which required a lot of effort, and the holes had to be made in binary notation, making it easy to make mistakes.

Therefore, as described in Japanese Unexamined Patent Publication No. 52-2560, a configuration is known in which a unit price setting plate is detachably attached to a product name stamp housing mounted on a label printer.

In this configuration, code holes are opened in the unit price setting plate in accordance with the unit price, but there is a drawback that data may be read by mistake if the code holes are clogged.

The present invention has been made in view of the above points, and includes a product name stamp housing that can be attached and detached from a label printer, and a plurality of holes that represent product name stamp codes corresponding to product name stamps provided on the housing and an even number or an odd number. An information setting unit is provided with a parity focus for performing parity bink, and an address corresponding to each product name stamp code is set in the storage area of the label printer to store unit price data corresponding to the product name stamp, and the information setting section The part photoelectrically reads the product name stamp code and parity focus, performs an even number parity change or an odd number parity change, and calls up the unit price data stored at the address corresponding to the product name stamp code, and then displays the product name stamp on the product name stamp housing. A hole is made to represent the code and information is obtained by photoelectrically reading it, making it possible to reliably read the data.The structure of the product name stamp housing itself is simple, and hundreds of types of product name stamps can be printed in a small space. Moreover, by pre-setting the unit price data to the address set corresponding to the product name stamp code, the unit price corresponding to the product name stamp can be easily changed. To provide a unit price setting device for a label printer that can be easily handled without requiring trouble such as repair.

Next, an embodiment of the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a product name stamp stand that is mounted so as to be vertically movable with respect to a mounting board (not shown) fixed in a label printer. A support shaft 2 that can be freely inserted is provided to protrude upward, and a light emitting element wiring bundle insertion hole 3 is located on one side of the support shaft 2, and a light emitting element wiring bundle insertion hole 3 and a product name stamp stand 10 are formed in the vertical direction on both sides of the width direction. A groove 4 for mounting on the light emitting side is formed, and a pair of threaded holes 5 for mounting on the light receiving side are formed in the width direction at the ends thereof.

Next, reference numeral 6 denotes a product name stamp housing that can be attached and detached from the lower surface of the product name stamp stand 1. On the lower surface of the product name stamp housing 6, a product name stamp (not shown) with a product name engraved thereon is formed, and one end A flat information setting section 1 protruding upward in the width direction is integrally formed in the section.

This information setting section 1 is formed with a product name mark code 8 in which a code corresponding to the product name mark and 121 is expressed in an array of a plurality of holes.

As shown in Fig. 2, this product name stamp code 8 is divided into 2 in binary notation depending on the blocked state of the 8 holes a to h, with 4 holes in each of the upper and lower rows.
56 types of product names can be distinguished.

In this example, if expressed in binary code, a can be thought of as the 8th binary digit and h as the 1st binary digit. Light, black circle is occluded)
Therefore, the product name stamp code 8 of 3.18°31 respectively
is expressed.

Furthermore, -MU of the information setting section 1 is provided with a parity focus k.

For this parity focus, even number parity change or odd number parity change is performed by a computer within the label printer main body.

For this parity bit, if the parity is an even number, count the product name stamp code hole in the product name stamp housing 6, and if it is an odd number, make a hole in the parity pin (k), and if the parity is an even number, leave the parity pin (k) closed. .

For example, in the case of product name mark number 3 in Figure 3 A, the number of holes is 2.
Since the number of holes is even, the parity bin (k) is collapsed, and in the example of product name mark No. 31 in Figure 3, the number of holes is 5, which is an odd number, so the hole is drilled at the parity pin k.

Then, when the product name stamp casing 6 is placed on the product name stamp stand 1, the data is read and input into the combinator 1.

Also, in the information setting section 7, there is a hole a in the upper row for the product name stamp code 8.
t b t Cy d and bottom row hole e.

A check bin t' 1 tJ formed by a hole having a diameter smaller than this hole a=h is provided between f, g, and h.

Only one of check bins i and j is opened.

Further, a knob 9 that projects horizontally forward is provided on the -(ill edge of the product name stamp housing 6).

Next, reference numeral 10 denotes a photoelectric code reading device for reading the product name mark code 8 of the information setting section I, in which a light emitting section and a light receiving section are arranged opposite to each other with a gap that allows the information setting section 7 to be inserted. The light emitting unit includes a light emitting element mounting PC board 12 on which a light emitting element 11 is provided, a light emitting side mounting base 13, and a transparent glass plate 14.
Similarly, the light receiving section is also formed by superposing the light receiving element mounting PC board 16 on which the light receiving element 15 is provided, the light receiving side mounting base 11, and the transparent glass plate 1B.

The light-emitting element mounting PC board 12 has an information setting section 70 provided in the product name stamp housing 6, with two rows of upper and lower holes corresponding to the holes a-h for product name stamp code B and the hole positions of check bins) i and j. Ten light emitting elements 11 are provided, five each.
The light emitting element wiring bundle 19 is fed from the back side of the PC board 12 to the upper part of the product name stamping stand 1 through the light emitting element wiring bundle insertion hole 3 formed in the product name stamping stand 1.

Further, the light-emitting side mounting base 13 has ten protective windows 20 into which the ten light-emitting elements 11 of the PC board 12 are respectively fitted.
This serves to fix the PC board 12 and protect the light emitting element 11.

Further, at two upper parts of the light-emitting side mounting base 13, mounting protrusions 21 having engagement claws 21a at the tips protrude upward, corresponding to the pair of light-emitting side mounting grooves 4 formed in the product name stamp base 1. By pushing upward along the groove 4, the engaging claw 21a at the tip of the mounting protrusion 21 is engaged and fixed to the upper surface of the product name stamp stand 1.

Further, the transparent glass plate 14 bonded to the surface of the light emitting side mount 13 opposite to the PC board 12 protects the head of the light emitting element 11 fitted in the protective window 20 of the mount 13. This prevents dust and grease from adhering to the surface of the element 11.

Further, the light emitting element 1 is mounted on the light receiving element mounting PC board 16.
The same number of light receiving elements 15 as 1 are arranged at positions facing the light emitting elements 11, respectively, and 22 is a wiring bundle thereof.

The light-receiving side mount 17 also has ten protective windows 23 into which the ten light-receiving elements 15 of the PC board 16 are respectively fitted.
In addition to fixing the PC board 16 and protecting the light receiving element 15, it also serves as a partition plate to prevent interference with adjacent elements 15 when multiple elements 15 are installed in a narrow space.

Moreover, the product name stamp stand 1 is provided on the upper part of the light receiving side mounting stand 17.
A mounting portion 23 is formed which has a pair of screw holes 24 communicating with a pair of light-receiving side mounting screw holes 5 formed in the mounting part 23. It is fixed to the product name stamp stand 1 by screwing with a screw 26 from above.

In addition, here, the attachment of the light-receiving side mounting base 11 to the product name stamp stand 1 was limited to a snap, but it may also be glued or fitted, and since the light-receiving side attachment base 17 also serves as the product name stamp stand 101 part, it has a reinforcing effect. ing.

In addition, the transparent glass plate 18 bonded to the surface of the light-receiving side growth table 17 opposite to the PC board 16 protects the head of the light-receiving element 15 fitted in the protective window 23 of the mounting table 11. This prevents dust and grease from adhering to the surface of the element 15.

Note that a light emitting diode is used as the light emitting element 11, and a phototransistor is used as the light receiving element 15.

As a result, the positive temperature characteristics of the phototransistor and the negative temperature characteristics of the light emitting diode cancel each other out, so there is no need to specially compensate the temperature of the phototransistor output or the load of the light emitting diode, and the distance between the light emitting and receiving light is short. Therefore, by selecting an appropriate value for the load resistance of the phototransistor, it is possible to input directly to the input of the IC gate, etc., without going through a drive circuit.

Further, a storage area provided in the label printer is provided with a unit price storage section (not shown) for storing unit price data corresponding to each product name stamp, in which an address corresponding to each product name stamp code is set.

In this unit price storage section, unit price data corresponding to each product name mark is pre-populated.

Next, the operation of this embodiment will be explained.

Now, when the product name stamp casing 6 is inserted into the product name stamp stand 1 equipped with the code reader 10, the product name stamp casing 6 passes between the optical axis formed by the light emitting element 11 and the light receiving element 15 of the code reader 100. Since the information setting section 1 of 1 is blocked, the light-receiving elements 15 at positions without holes have no light detection output, and the light-receiving elements 15 at positions with holes have a light detection output.

This output is input to the computer, and if the parity is even and the number of code holes is odd, the parity focus is open, so the computer counts the holes in the data and determines that the data is correct if the number of holes is correct.

Then, the product name stamp code is read from the output from the CO)"-TL and sent to the label printer main body.

From this product name stamp code, the main unit calls unit price data previously stored in the unit price storage section at the address corresponding to the product name stamp code, and the unit price is automatically entered as data for calculation, display, and printing.

In addition, since the check bits i and j of the information setting section 7 are set so that j is closed and only i is left open, the data reading conditions are set such that the light receiving element 15 at the position of i is "bright" and the light receiving element 15 at the position of j is "bright". By setting the condition when the human power is "'dark 1", it is possible to prevent reading and importing incorrect data when the product name stamp housing 6 is not completely seated.

In addition, since the hole i is made smaller in diameter than the other hole, that is, the hole representing product name mark code 8, the light will pass through the hole i after the light passes completely through the other holes, and the hole i will pass through the hole i. ,
In combination with the arrangement of the holes in j, it is possible to prevent data from being read at an incorrect position.

In addition, in FIG. 5, the parity focus k is a and b.

It is provided in columns c and d, but is limited to columns e and f.

It may be provided in columns g and h.

In addition, in the above embodiment, the product name stamp code 8 is inserted into the eight holes a-h.
It was possible to distinguish 256 types of product name stamps using the binary system, but if you want to distinguish a large number of products, you can simply increase the number of holes.

By the way, if you use BCD code, you can represent up to 100 types with 8 holes.

In addition, when the number or arrangement of the data holes is changed as described above, the arrangement of the light emitting elements 11 on the light emitting element mounting PC board 12 and the arrangement of the light receiving elements 15 on the light receiving element mounting PC board 16 and each mounting will be changed. The arrangement of the protective windows 20.23 of the stand 13.17 is provided to correspond to the arrangement of the data holes, respectively.

According to the present invention, a hole representing a product name stamp code corresponding to the product name mark provided on the casing and a hole representing an even or odd parity check are formed in a product name stamp housing that is detachably attached to a label printer. An information setting section is provided, and an address corresponding to each product name stamp code is set in the storage area of the label printer, and a unit price storage section is provided in which unit price data for each product name stamp is stored in advance. The product name stamp code is photoelectrically read from the information setting section of the casing, and the unit price data stored in advance at the address corresponding to the read product name stamp code is called from the unit price storage section. When obtaining information by photoelectrically reading a hole to represent a product name code on the body, a plurality of product name mark codes corresponding to the product name mark provided in the product name mark housing removably attached to the label printer are provided. If the hole is clogged, the parity bit performs an even parity check or odd parity check to ensure that incorrect data is not read due to a clogged hole, and that accurate data is read. Not only is it easy to distinguish between hundreds of types of product name stamps in a small space, but also the unit price for the product name stamp can be easily changed by pre-setting the unit price data to the address set corresponding to the product name stamp code. , price fluctuations can be easily dealt with without the need for troubleshooting, such as fixing holes in the information setting section.
