Description

[Detailed Description of the Invention] The present invention relates to a product code setting method in a weighing label printer that prints and issues data regarding weighed products on labels, and its purpose is to improve operability when keying in from a numeric keypad. .

In the commonly used multi-digit code numbers, the upper digit is the major classification of the code number, the middle between the upper and lower digits is the medium classification, and the lower digit is the minor classification. has been done. For example, as a product code for the weighing label printer, the upper digit "15" of the product code "15001" represents the type of pork, beef, etc., and the lower digit "001" represents the type such as shoulder loin. represents.

Possible means for setting such a product code include a multi-digit digital switch, a numeric keypad, and the like. Digital switches are suitable for changing only a part of the code, but the changing operation is cumbersome, while numeric keys are easier to operate than digital switches, but
Even though only part of the code needs to be changed, traditional setup methods force users to rekey all digits. For example, in the case of a numeric keypad, in order to change the minimum total of "1" of the already set product code F "15001" to "2", it is necessary to key in "15002".

To explain in detail the conventional setting method using a numeric keypad, this involves keying in the product code in order from the upper digit, and each time the key is pressed in, all the codes that have already been set are shifted to the left toward the upper digit, and the latest The key-in code is entered in the least significant digit. In this case, it is necessary to operate the clear key when changing settings.

Therefore, when the present invention detects a setting change instruction, only the lowest digit code of the past multi-digit product code that has already been written is updated to the 4i81st code keyed in from the numeric keypad, and the second and subsequent The key-in is performed by sequentially shifting the first and subsequent key-in codes toward the upper digits without shifting the remaining codes that were not rewritten after the detection of the setting change instruction among the past product codes. The key-in code is updated sequentially from the beginning, and the latest key-in code is always input in the least significant digit, which improves the setting change operation when only the least significant digit of the product code needs to be changed.

The setting method of the present invention will be explained below based on a specific example.

FIG. 1 shows the configuration of a product code setting section of a weighing label printer. (1) is a numeric keypad provided on the operation panel of the weighing label printer, and is used for setting unit price, tare weight, and product code according to the operation of mode switching keyboard (2). Here, mode switching keyboard (2)
The old key represents a switch for changing the mode of the numeric keypad (1) to product code setting. (3) is a numeric keypad encoder which outputs numeric keypad data (4) and strobe pulses (5) based on signals output from the numeric keypad (1) in accordance with operated numeric keys, etc. (6) is a counter whose contents are reset to "0" each time the t+ key is operated, and which uses the strobe pulse (5) as a counting input; (7) is an output to
- Counter decoders (8o) to (84) that set t4 to logic levels "L" and "O" as shown in the table below, respectively, use the outputs (to) to (t4) of counter decoder (7) as control signals as described above. The AND gate gates the passage of the strobe signal (5), and (9) is a shift register consisting of registers (Ro) to (R4) in which data inputs are connected in series. Ten key data (4) from the ten key encoder (4) is supplied, and the outputs of the AND GO (8o) to (84) are applied as shift pulses to each register (Ro) to (R4), respectively. QO is a shift register (9
) is a product code reading unit that reads data output in parallel digits and uses it as a product code.

<Table> With this configuration, the product code setting operation is performed in the second step.
It will look like Figure 3.

Figure 2 shows the shift register (9) from the upper digit of K to “oooooo”.
" has already been set, and the operation process is shown when changing it to "00012". First, when the ffi key is operated, the counter (6) is reset and the output of the counter decoder (7) is i0=1. , t1 to t4=0, and AND gates (81) to (84) are inhibited.

Here, when you operate the l key of the numeric keypad (1), the code “
l"Tost o-': l Hals (5) is input and the register (Ro) is updated to the code O-1. Furthermore, when the l key is operated, the strobe pulse (5) and the register (R
o) After the update is completed, the contents of the counter (6) are incremented, and the output of the tank decoder (7) changes to to, ti=l, and t2 to t4=0 to prepare for the next key-in. Next, when the l key of the numeric keypad (1) is operated, the strobe pulse (5
) H&G) register (
Since it is applied to the register (Ro ) (R1), the register (Ro
) is shifted to the register (R1), the contents of the register (R1) are updated to the code "1", and the register (Ro) is updated to the code "2". As a result, the product code is updated from the upper digit to "00012". The setting contents read by the product code reading unit 00 are displayed on a dedicated display section provided on the operation panel or the like, or on a price display section where the price calculated from the weight value and the set unit price is displayed. Ru.

Figure 3 shows the operation process for changing the product code "12345" from the first digit to "12q90".As in the case of Figure 2, first press the m key to instruct the setting change. When the l key of the numeric keypad (1) is operated as the first key-in after the operation, only the code in the register (Ro) of the least significant digit is updated to "5"-6. As a result of this update, the product code has become "12346". Then, when the L key is operated as the second key-in, the past product code "12345" remains unrewritten after the M key operation is detected.
1234", the code "6" of the first keyed-in register (Ro) is shifted, the register (R1) is updated to the code "6", and the latest key-in code "9" is shifted to the register (Ro). ). As a result of this update, the product code has become "12369".
When you press the 0 key as the second key-in, the upper digit “
123'', shift the codes ``6'' and 9'' in registers (R1) (RO) toward the upper digits, and set the registers (R2XR1) to codes ``6'' and 9, respectively, to the latest key-in code ``0''. is input into the register (RO), and the product code is changed to "12690".

In this way, each time a new code is keyed in for a product code that has already been keyed in, the newly keyed in code is shifted toward the upper digits and the previously keyed product code is updated from the lower digit side. Therefore, there is no need to rekey the upper digit code, which does not require change, and operability is improved. FIG. 4 shows an example of a label issued by a weighing label printer, and in cases where PO8 processing is performed, a barcode (2) corresponding to the product code Qυ may also be printed.

As explained above, according to the product code setting method of the present invention, the setting can be completed by rekeying only the code that needs to be changed and the code on the lower digit side of that code. It is possible to prevent deterioration in operability due to this, and it is expected that the operability of the weighing label printer will be improved.
