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 product name stamp body with a product name stamp provided with a unit price setting board in which the unit price corresponding to the product name stamp is indicated by a hole etc. Alternatively, the unit price was calculated using photoelectric detection using LEDs 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 have to be re-drilled, which is time-consuming, and the holes have to be drilled using a binary system, which makes it easy to make mistakes. Furthermore, there is a risk that the data may be read when the product name seal lotus body is not completely seated, that is, at an incorrect position, and incorrect code data may be imported. In view of these points, the present invention includes a product name printing unit that can be attached to and detached from a label printer.
An information setting section is provided with a plurality of holes and check bits representing the product name stamp code corresponding to the product name stamp provided on the body, and an address corresponding to each product name stamp is stored in the storage area in the label printer. The unit price data corresponding to the product name stamp is set, the product name stamp code is photoelectrically read from the information setting section, and the check bit detects that the product name stamp cover is securely set in the specified position. The unit price data stored in the address corresponding to the product name stamp code is called up only at the time, and a hole is made in the product name stamp crab body to represent the product name stamp code and the information is obtained by photoelectrically reading the product name stamp code. The structure of the body itself is simple, and hundreds of types of product name stamps can be distinguished in a small space.
By resetting the unit price data to the address set corresponding to the address, you can easily change the unit price corresponding to the product name stamp, and there is no need to re-drill the holes in the information setting section in response to price fluctuations. To provide a unit price setting device for a label printer, which can easily deal with errors, prevent data from being read at an incorrect position in an information setting section, and prevent erroneous data from being taken in.

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 for special temperature compensation 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 can be input immediately to the input of the IC gate, etc., without passing through the 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, each of which has an address corresponding to each product name stamp code set therein. .

Unit price data corresponding to each product name mark is preset in this unit price storage section. Next, the operation of this embodiment will be explained. Now, when the product name stamp housing 6 is inserted into the product name stamp stand 1 equipped with the code processing device 10, the product name stamp housing 6 is inserted between the optical axis formed by the light emitting element 11 and the light receiving element 15 of the code reading device 10. The information setting section 7 of No. 6 blocks the light, and the light receiving elements 15 at positions without holes have no light detection output, while the light receiving elements 15 at positions with holes have a light detection output.

The product name stamp code is read from this world power and check bit i
, i, the product name stamp code is sent to the label printer body only when the product name stamp weight body 6 is detected to be in the correct position. From this product name stamp code, the main body 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 set as data for calculation, display, and printing. In addition, since the check bits i and j of the information setting section 7 are closed at i and a hole is opened only at i, the data reading conditions are set such that the input to the light receiving element 15 at position i is "bright" and the input to the light receiving element 15 at position j is "bright". By setting the condition that the input is "floor", it is possible to prevent the data from being modestly taken in when the product name seal case 6 is not completely seated.

In addition, since the diameter of the hole j is made smaller than the other hole, that is, the hole representing the 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 ，
By matching the arrangement of the holes in i, it is possible to prevent data from being read at an incorrect position. In the above embodiment, the holes a to h for the product name stamp code 8 are provided in the information setting section 7 in two columns, upper and lower, and the check bits i and j are arranged at the right end position of each column, but the present invention is not limited to this. , as shown in FIG.
, f, g, and h.

In addition, as shown in FIG.
It is also possible to provide one parity bit k. This parity bit k is used to perform an even parity check or an odd parity check by a computer in the label printer main body to prevent incorrect data from being read due to hole clogging or the like. For example, if even parity is used, tell the product name stamp code hole of the product name stamp body 6, and if it is an odd number, a hole is made in the parity bit k, and if it is an even number, the parity bit k is crushed. In the example of product name mark No. 3 in Fig. 3 7, the number of holes is 2, which is an even number, so the parity bit k is crushed, and in the example of product name mark No. 31 in Fig. 3 C, the number of holes is 5, an odd number, so the parity bit k is crushed. Leave a hole open. When the product name stamp case 6 is set on the product name stamp stand 1, data is stored and input into the computer.
The computer tells the number of data holes, including the parity bit k, and determines that the data is correct if it is an even number. The more this parity check is performed, the more secure the data will be. In FIG. 5, parity bit k is provided in columns a and d, but the parity bit is not limited to this, and e may be provided in column h. In addition, Figure 6 shows data holes a to h that indicate product name stamp code 8 if check bits i and j are correct.
An example is shown in which the position of can be arbitrary. In addition, in the above embodiment, the product name mark code 8 is represented by eight holes a to h, and 25 kinds of product name marks can be distinguished in binary notation, but if you want to distinguish more, you can increase the number of holes. good.

Furthermore, if you use the BCD code, you can represent up to 10 lotuses 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. Protective window 20 of stand 13, 17,
23 arrays are provided, each corresponding to the array of data holes. According to the present invention, the product name stamp body that can be attached and detached from the label printer is provided with an information setting section in which a plurality of holes and check bits are formed to represent the product name stamp code corresponding to the product name stamp provided on the pupil body. , in the storage area inside the label printer.
A unit price storage unit is provided in which a corresponding address is set for each product name stamp code and unit price data for each product name stamp is stored in advance, and the product name is photoelectrically stamped from the information setting section of the product name stamp case attached to the outside of the label printer. The code is read and stored in advance in the address corresponding to the read product name stamp code from the unit price storage section only when it is detected by the check bit that the product name stamp casing is securely set in the predetermined position of the label printer. Since I called up the unit price data,
The product name stamp body itself has a simple structure because a hole is made in the product name stamp body to indicate the product name stamp code, and the information is obtained by photoelectrically picking up the code. By resetting the unit price data to the address set corresponding to the product name stamp code, you can easily change the unit price for the product name stamp, and you can also easily change the unit price for the product name stamp by re-drilling the holes in the information setting section in response to price fluctuations. This can be easily handled without any effort, and by providing a check bit, it is possible to prevent data from being read in an incorrect position in the information setting section and erroneous code data from being taken in.
