When the function key FK1 is pressed for the first time, the operation shifts to NK2, and when it is pressed for the second time, the setting contents of the corresponding JOB# are displayed. Each time the function key FK2 is pressed, it is automatically updated to the next item # or the next JOB #. Function key FK3 displays the setting contents of the next JOB# when pressed. When checking settings, press and hold FK3 one after another.

(3) Data format of data registration memory FIG. 9 shows the format of the data registration memory during data entry in execution mode.

The initial registration record and business classification record are fixed for each delivery system. Heading, date, and footing records can be fixed for each job of each data entry selected for the job. Initial registration, business classification, heading, and footing records may not exist.

Each record other than business classification is composed of a plurality of items as shown in FIG.

(4) Parameter settings for each record of hetting, date ailment, and footing Hetting is the storage of data such as the total of each quantity in terms of quantities, the total of amounts in terms of amounts, or the year, month, day, hour, and minute of input or output. Parameter settings can be made for, for example, JOB #101-0114 and items #10-14.

Table 2 shows the setting method.

Further, the date information is a part that shows details such as, for example, the unit price and quantity of each product. The setting method is shown in Table 3-1 and Table 3-2.

A footing record is a record placed after the last date record.
For example, it is used for closing purposes, such as memorizing the total amount of money in a date record.
The setting method is shown in Table 4.

Hereinafter, specific setting methods will be explained according to Tables 2 to 4.

[Item #10] Specifying various information for items (a) Item length Specify the required length (digit length) for each item. However, it includes C/D check code, symbols such as decimal point ".", sign "±", and item classification code. The digit length specified here is allocated to the data registration memory.

(b) Display area Monitors the input content using the numeric keypad or displays the input content when inputting the barcode reader TPR. Specify the number of lines, columns, and column length for the area.

(c) Item delimiter code When storing each input item in the data registration memory, specify whether or not to store a code representing the delimiter of each item. When storing, specify the code (1 digit). Note that the code specifications are different for 4BIT and 8BIT.

(d) Input end key When inputting using the numeric keypad, specify the key that indicates the end of inputting an item using a key code. When the key specified here is input, it is assumed that the input of the corresponding item is completed.

(e) Calendar function The system has two calendar functions: writing (initial registration items only) and reading (heading and date-ail items only). “Yes” or “No” can be specified for these functions.

When "Yes" is specified, specify only one of the following contents: "Year, Month, Day,""Hour,Minute,""Year, Month, Day, Day of the Week, Hour, Minute."

(f) Specify whether TPR input is possible. Since numeric keypad input is always possible for any item, multiple input with the numeric keypad is required for items designated as allowing TPR input.

[Item #11] Specifying various check methods (a) Checking month and day, etc. For checking "month/day", "hour/minute", "month/Sunday/hour/minute", for example, 00≦hour≦23, 00≦minute≦59 Perform the above checks.

(b) Range check This range check, for example, checks whether the input amount is within the range from the lower limit to the upper limit.For example, 10 range tables are available for combinations of the upper and lower limits. It can be specified from (01 to 10). For one item, if there is no other check specification (for example, month/day check, etc.), multiple types and up to 5 types of checks can be performed for one item. In that case, it is performed by "OR" for each type. . Check only significant figures, sign,
Ignore the decimal point.

Table 5 shows the above range table.

(c) Check, digit [C/D] check This is a C/D check for input items. C/D checks can be performed by adding other items to the beginning of input items.

FIG. 11 shows a weight assignment method when n ₁ , n ₂ , n ₃ , n ₄ , and n ₅ are specified as weights.

Furthermore, up to six types of C/D check contents can be specified from the C/D table shown in Table 6.

The parameters to be set include the number of the C/D table, whether or not to add other items, and, if added, the item number.

(d) Comparison check with initial setting memory The input data is compared with the data stored in the initial setting memory.

As a result of the comparison, if a match is found, the input data is processed, and if it is not a match, an error occurs.

(e) Total check This is an equality check between the input data values of the heading and date items and the totalizer (for addition) [explained later] provided in the system. An example of this is shown in FIG. 12.

This summation check can be used for heading and date records. Here, specify one of the system totalizer numbers (01 to 04).

The system totalizer value (total value) that was calculated is cleared when this check is completed. The system totalizer will be described in detail in the section "(c) Use of the system totalizer" below.

(f) Master data search check This check is possible for heading and date-ail input items, and the processing when this check is specified in the input item is as follows.

Note that FIG. 13 shows the configuration of the master aisle.

(f-1) Specifications when searching for master data include specifying key data in input data and specifying the format of master registration memory.

(f-2) Search from the beginning of the date record group in the master registration memory using the specified input data key.

(b) When it is not in the master registration memory You can specify whether to generate an error or ignore it.

●When an error occurs, a high-pitched long buzzer sounds. The long buzzer can be turned off by pressing the CE key among the function keys, and this item must be entered again.

●When ignored After processing the input data, move on to input the next item.

(b) When it is in the master registration memory MAX10 of each item of master data
The items are displayed on the liquid crystal display 11.
The displayed contents are referred to when inputting date items.

●Specifying the display area for each item of master data (do this for each data entry) Specify the line, column, and column length to be displayed for each item. When the line specification is set to "0", that item is not displayed.

The position and length of each item of master data and the designation of the edit type for display are shown in Tables 9 and 10, respectively.

In Table 10, the edit specifications for display are as follows.

“0”…No editing → Display the image in memory as is.

“1”…Suppress leading zeros and display only the significant digits in memory.

“2”…Display with leading zeros suppressed to the first decimal place.

“3”…Display with leading zeros suppressed to the second decimal place.

Note that the contents of the displayed master data are deleted when the input of the final item of the heading and date record is completed.

For this master data search check,
This section will be explained again later in <Master File Function>.

(g) Data registered check This check is possible only for date input items, and the processing when this check is specified in an input item is as follows.

Similar to the memory search function of the date record, edit the input data (positive integer) in the same way as the memory format, and use this as a key to search from the beginning of the same date record group that is currently being input in the data registration memory. search for.

(b) When the information has already been entered: Displays the contents of the searched date record and sounds a high-pitched buzzer. The display is the same as the date email input screen currently being entered.
Editing during display is performed as follows.

*Fixed digit items are displayed as images in memory.

*Variable digit items are displayed with leading zeros suppressed. (If there is a decimal part, "." is also displayed.) The subsequent processing is as follows.

*When the deletion key is entered, the buzzer and display contents are turned off, and the entire searched date record in the data registration memory is filled with the specified special code (same as the memory code when deleting memory search). This item will be entered again.

*When a key not to be deleted is entered, the buzzer and displayed content will be turned off and the item will be entered again. It is possible to specify a key for deleting or not deleting the searched date record on the data registration memory.

(b) When the input data has not been completed After processing the input data, move on to input the next item.

[Item #12] Memory editing method, etc. The specification method for the memory editing method differs depending on the type of heading, date-ailing, and footing, but here we will mainly explain the memory editing method for date-ail records shown in Table 3. .

(a) Memory editing method (1) “00” to “02” Decimal point reference and number of decimal digits Specify the position of the decimal point in the memory (0 to 2 digits; if “0” is specified, there is no decimal point). With this specification, input data is edited based on the specified decimal point position. In this case, the overflow is cut and the shortfall is filled with zeros. If there is no decimal point, edit with the right end as the decimal point. Whether or not to memorize the decimal point position is
Depends on system parameter settings.

(2) Delete the last digit of “10” Delete the last digit (C/D value) of the input data and store it right-justified. Cut the overflow and fill in the shortage with zero.

(3) “2n” C/D addition Add the C/D value after the last digit of the input data and store it right-aligned. That is, "n" designates the item number of the C/D table (n: 1 to 6). In this case as well, the overflow is cut and the shortage is filled with zeros.

(b) Addition of other items (data synthesis) Addition of other items is a type of data synthesis, and includes other items (heading or date ailment).
Synthesize with the input data of

In this case, specify the other item addition code "30" in the memory editing method of (a), and then specify the item number of the other item to be added in (b).

(c) Use of system totalizers This system has a total of four totalizers (14 digits for the integer part and 2 digits for the decimal part), which can be used in the following ways.

*Save input data.

*Add input data.

*Read the system totalizer data.

* Check the input data and system totalizer value for equality.

*Check the values of system totalizers for equality.

By combining these usage methods with input items, settings can be made, for example, as shown in Table 11 below.

Usable range (1) Use in heading or date record As shown in Figure 16a, the total is a numeric key input item, and the input value is the sum of items 1 to n. An equality check is performed between the input value and the total value (added to the system totalizer when inputting items 1 to n) (see the section on total check). In addition,
At this time, it is not possible to input total items from the system totalizer without inputting them using the numeric keys.

(2) Use in date record and footing record As shown in Figure 16b, when inputting the total of the input items of the date record in the footing record item, the total numeric key input value and The total value (added to the system totalizer when inputting item n) is checked for equality. It is also possible to input the total from the system totalizer without using the numeric keypad.

(3) Use in heading records, date-ail records, and footing records As shown in Figure 16c, enter the total value of the date-ail record input items in the heading record input items. (Save it in the system totalizer when inputting the total n),
When entering the footing record, perform an equality check with the total value of the input items of the date record (when inputting item n, add it to a system totalizer separate from the one for saving) and the input value of heading. .

[Item #13] Designation of key input method For date record, four types of key input methods can be set. There is only one type of hedging and footing.

(a) Specifying the total number of digits However, the total number of digits here is the number of significant figures,
Does not include the decimal point “.” or sign.

(b) Number of decimal places Maximum of 2 digits, if there is no decimal part, specify “00”.

(c) Input mode “0”…The number of digits is fixed and only positive integers can be entered.

“-” and “.” cannot be entered.

“1”…Positive integers with various numbers of digits can be entered.

“-” and “.” cannot be entered.

“2”…Positive or negative integers of various numbers of digits can be entered. However, you cannot input anything with a decimal point ".".

"3"...Positive real numbers of various numbers of digits can be input, but "-" cannot be input.

“4”…Positive and negative real numbers of various numbers of digits can be input.

(d) Omission of number on the numeric keypad Whether or not the number on the numeric keypad can be omitted, and if it can be omitted, whether it is considered to be an input of “0”.
Specify whether to consider it as an input of “1”. If omitting the number is specified, only the end key can be input (described in detail later).

(e) Input editing (a) Right-justify input data “00” Align the input data to the right, and fill in the missing number of input digits with zeros in front.

(b) Left-justification of input data The input data is left-justified, and the missing part is later filled in with filler code (HEX) (“0” to “9”).
Fill in one digit).

(c) Replacement start digit during data synthesis First, data synthesis will be explained.

When composing the data described above, specify the replacement start digit.

FIG. 14 shows an example of data synthesis for input item 2. As shown in Figure 14, in input item 2, the classification code is entered in the top three digits and the product code is entered in the bottom five digits.
If a 5-digit number corresponding to a product code is input, this product code is combined with the previous classification code. In this case, the first digit P to be replaced with the current data (product code) is specified in the key input method of [Item #11] described below.

The data (classification code and product code) synthesized in this way is input to input item "2" of the current record.

Such data composition has the effect of making it possible to extremely simplify input operations for data that have some common data.

FIG. 15 shows a data synthesis flow during data entry in execution mode.

When data entry for one record is started using the numeric keypad or TPR, the input data is displayed on the display, and in step 101 it is determined whether or not to combine it with the previous input data. , and other edits specified in step 102 are performed. If "YES", synthesis and editing with the previous input data is performed in step 103. This synthesis method is as described above.

Then, the data after input editing is sent to step 104.
is displayed, allowing you to check the composite data.

Further, various checks as described below are performed in step 105, and if the checks are cleared, memory editing is performed in step 106, and the data is saved in the write buffer. This operation is repeated until it is determined in step 107 that data entry up to the last item has been made. After inputting one record, the input data is set in the data memory in step 108, and data entry for the next record is performed. Transition.

Note that when the above (b) or (c) is specified, the edited data is displayed again in the monitoring area after the input using the numeric keypad is completed.

In addition, various checks regarding input data can be done by
Perform this on the data after editing the input data.

[Item #14, 15] Specify TPR method If you want to complete the input with one scan, specify the input method in item #14. If you want to complete the input with multiple scans, specify the input method in item #15.

The specification is basically made by specifying the number (JOB#) in the TPR input table (Table 12) below.

Specifically, with reference to Table 12, the number of digits to read, the starting position of valid data, the effective data length, the presence or absence of a classification code, the classification code if it is present, and the type of barcode (NW-7, JAN ( 8, 13 digits), 2out
of 5, iNTERLEAVED 2out of 5), check digit table number, “-”, “+”, “.”
Specify the decimal value etc.

For multiple scans, specify the input end condition.

The input termination conditions are: *When a TPR input other than the specified number of read digits or classification is received, or when a key input is received.

*0 to 9, when a TPR input other than "." is received ("-" is regarded as negative data, others are regarded as positive data).

<C/D calculation method for data including symbols such as decimal points> To prevent barcode reading errors,
A check digit (C/D) check is performed on the read data. Similarly, when inputting data using the numeric keypad, a C/D check is performed to prevent numeric input errors. However, C/D
Normally, calculations can only handle integers. However, when the data includes a decimal point or + or - symbols, C/D calculation cannot be performed as is. Therefore, in advance, for the decimal point and + and - signs, 0 to 99
When performing C/D calculation after setting the number of
This allows calculations to be made using the set numbers instead of symbols. By doing this,
It is possible to calculate C/D for data including symbols other than numbers.

The designation method in this case is shown in item #“03” on the TPR input table shown in Table 12.

In this item # “03”, in addition to specifying the barcode type and C/D type mentioned above, the “-” symbol,
Assign any two-digit value from 00 to 99 to the "+" symbol and the decimal point symbol ".". In other words,
Convert these symbols to appropriate numerical values. If you do this, for all real numbers including plus and minus signed integers and decimal points,
A C/D check can now be executed.

A detailed description will now be given of the C/D check operation flow shown in FIG.

In step 101, from TPR, for example, “-
1234.67” is input, step 1 determines whether or not to perform a C/D check for this input item.
If it is determined in step 02 and a C/D check is to be performed, in step 103, set "-" and "." to the specified decimal value, such as "11" and "31".
Replace with

Therefore, the C/D calculation in step 104 is performed for "1112343167", and the calculation result and C/D equal check are performed in step 1.
It will be held in 06. If they are not equal, an error will be displayed.

In the above example, “+”, “-” and decimal point “.”
Although a case has been described in which the symbols include "¥", for example, the above concept can be extended to other symbols such as "¥" representing Japanese yen.

In addition to the functions clarified in the explanation of the setting method above, this data terminal device can selectively set various functions.

The main functions will be explained by function below.

<Setting data error check> In order to execute multiple types of business programs from one program, that is, multiple types of application specifications, this device sets various parameters and operates the program according to the set parameters. Its basic feature is that it allows Therefore, if the set parameters change due to noise, malfunction, etc., malfunction will naturally occur, and in extreme cases, the system will go out of control.
Therefore, the parameters are required to have the same reliability as the program.

By the way, in the past, a check such as a sum check has been performed on the program section, but no check has been performed on the parameter section.

From this point of view, the present invention prevents equipment malfunctions by checking the parameter section in the same way as the program section.

This checking method of the parameter section is characteristically shown in FIG.

In the program routine, various parameters are set in sequence, and when the settings are completed, the power switch is normally turned off, assuming that the program setting mode has been completed.

This power switch OFF operation (you may also turn on the parameter setting end key) will trigger the
P-OFF routine POR is executed.

In this POR, a check code such as a check sum code is calculated for the parameter section in which the set parameters are stored, and is set in a predetermined memory area.

Then, in order to execute the business program set by the parameter settings, when the power switch is turned on or the application program start function key is pressed, the program starts as shown in FIG. After determining whether it is loaded or not, a thumb check is performed in the next step.

In this thumb check, a thumb check is performed for both the program and the aforementioned parameters. Therefore, if not only the program but also the parameter section is corrupted for some reason, a thumb check error will be displayed and the execution of the program will be stopped. In this case, in the parameter setting mode,
Necessary checks can be performed on the setting parameters, for example, setting parameters stored in memory can be sequentially displayed and compared with a setting data table.

In this way, it is possible to check not only the program section but also the parameter section, so that garbled setting parameters can be discovered before they occur, making it possible to always execute the correct business program.

<Master file function> The master file function according to the present invention has the following features: (a) The data terminal machine can have multiple types of data as a master file that can be referenced when performing entry work, and (b) Entry data can be You can use the key to search the master file and display related data, (c) you can freely configure the master file configuration, (d) you can select the data required for each job and display it in any position, (E) The displayed master file can be read as data, (F) The master file can be loaded from the host machine and can be modified manually, and (G) When one record of data has been entered, the data displayed for reference can be It consists of a series of functions that erase master data.

By providing such a function, (a) the corresponding reference data can be referenced during data entry, making entry easier, (b) entry errors can be prevented, and (c) data can be searched separately. It saves time and effort, (d) various data can be managed in files, (e) the master file can be searched and modified as needed, and (f) master data can be displayed on a free map. You can get many advantages.

(a) Master file structure As shown in FIG. 18, the master file structure is defined as a set of records of the same length, starting with a numerical value indicating the starting digit of the first record of the master file.

As shown in Figure 19, each record starts with data indicating the starting digit of key data MKey,
It is configured to include key data MKey, and is set so that a key search can be performed using key data MKey when searching the master file.

Set the master file according to Tables 13 and 14.

The items that make up each record are the 1st item to the 10th item, and the item length and starting digit of each item are specified.

Furthermore, the display method for master data verification is set by specifying the display line li, display start digit di, and digit length ni for each item i in item #21 of JOB #4301. Also, the editing method during display is set according to Table 15.

FIG. 20 shows a display example with the above settings.

(b) Creating a master file The master file of this device is created by reading the master file of the host machine in parallel or serially.

In the flow shown in FIG. 21, when master file reception job A is selected in job selection, this device is connected to the host machine via a parallel or serial reception cable,
Start reading by pressing the receive key,
A master file can be created by storing it in a memory area reserved for the master file in this device.

For example, multiple types of master files can be created for each type of work, such as ordering work and inventory work.

In addition, in FIG. 21, when master file correction work B is selected, manual correction can be performed while monitoring the data of the master file once created.

(c) Master data search check during data entry In Figure 21, when data entry C is selected in the job selection and the business content of data entry (ordering, inventory, etc.) is specified, the master data search check is as follows: This is done as follows. However, this master data search check is “6000” of the check methods in Table 3-1.
This is performed only when the master data search check code is specified.

As for the check method in this case, two methods C- and C- are possible, as shown in FIG.

(1) C-Method First, in step 401, key data within the input data to be searched is specified.

The parameter settings of the key data in this input data are according to Table 16.

FIG. 22 shows details of the above C-method.

In step 501, when data for one record is input, the function key is pressed.
When FK is pressed, it is determined in step 502 whether or not to perform a master data retrieval check. If the check is to be performed, the key data in the entry data is retrieved in step 503.
RKey is the key data in the master file
Search each record to see if it matches the MKey.

If the RKey and MKey match in this search, the master file record having that MKey is displayed according to the display method described above.

Enter other items by referring to the display contents of this master aisle record.

When the entry for one record is completed, the next record is entered and the above verification check is performed again.

Note that if there is no match in the above search, an error occurs or is ignored depending on the set parameters.

(2) C-method In this case, first, in step 406 of FIG. 21, the first record of the master file is displayed.

If the data is not the intended one, press the forward function key FW to display the second record. In this way, the master aisle records are monitored one after another, and when the desired data is displayed, a predetermined function key FK is pressed in step 407 to display the key data of the master aisle record.
MKey is read (step 408), and this key data MKey is stored as a corresponding item of input data. Continue with step 409
Then, refer to the contents of the displayed master file record and enter data for other items. For other items, MKey
Similarly to the reading of , the data of the corresponding item in the master aisle record may be read as is and stored in memory. When data entry for one record is completed, the same entry operation (including verification) as described above may be continued for the next record.

<Decimal point memory selection> The data handled by the data terminal is
It can be an integer or a real number. Also, even real numbers can be variable-point data or fixed-point data. When storing these data, variable point data requires storage of decimal point data, but integer or fixed point data does not necessarily require storage of decimal point data. On the other hand, when considering the case where data is processed by connecting to a rear processor, it may be easier to process data even if it is integer or fixed-point data by storing decimal-point data. In this way, the necessity of storing the decimal point differs depending on various conditions. Therefore, it is possible to freely set whether or not to memorize the decimal point,
The purpose of <decimal point memory selection> is to be able to respond according to the situation. Another purpose is to save memory by omitting unnecessary data.

As shown in FIG. 23, in the execution mode,
When the job selection operation is performed in step 101 and the data entry job is selected, the process proceeds to step 102.
In step 103, a business program corresponding to the data entry business is called, and data is input using the numeric keypad in step 103 or data is entered in step 104.
Data entry by TPR is executed.

In step 105, it is determined whether or not to store the data based on the decimal point. If NO, the input data is edited by another specified editing method such as left-justified or right-justified, and stored in the memory. do.

On the other hand, in the case of YES, it is determined in step 107 whether or not to store the decimal point, and if storing the decimal point is specified, the data is stored with the decimal point added in step 108. Also, if it is specified not to remember the decimal point,
Store data without a decimal point.

As above, steps 106, 108, 10
After the input data is stored in one of steps 9, it is determined in step 110 whether or not the data entry has been completed, and if it has not been completed, the process returns to step 103 or step 104.
Perform data input using .

Furthermore, if it is determined that the data entry has been completed, this data entry operation is completed and the process moves on to necessary subsequent operations.

In the above program, for example, when "123.45" is input using the numeric keypad, step 10 is executed.
8, “00123.45” is memorized and step 109
Then "0012345" will be stored.

Whether or not to use the decimal point as a reference, whether to store the decimal point, etc. are specified as parameters in the program setting mode, and in the execution mode, these parameters are determined and data input is executed.

<Settings for each item, such as omitting the number on the numeric keypad> This function has been explained using the setting method of date record, etc., but its purpose is as follows.

In data terminal machines, data entry is usually performed using a numeric keypad and function keys. In ordering operations, the order unit is often decided for each store, such as one box, one dozen, or one carton, depending on the product. Also,
In inventory management operations, quantity entry data often contains 0. Therefore, 1 → function key, 0
→Entries such as the function key will be repeated.

Therefore, you can omit input on the numeric keypad and simply press the function key to input "1" or "0".
The purpose is to have the value automatically entered.

More specifically, FIG. 24 shows the operation flow in the execution mode.

As shown in Figure 24, when one of the data entry jobs is selected during job selection, data entry is normally performed using the numeric keypad or TPR, but this data entry can be omitted and a specific fan can be selected. button may be pressed.

In this case, if such an input method is designated as invalid in the parameter setting in the setting mode, an error is immediately determined in step 101.

If it is specified as valid, it is determined in step 102 whether or not to treat it as "1".
If YES, "1" is stored for the corresponding item in step 103. If it is not treated as "1", "0" is stored in step 104.

This numeric abbreviation method can be set for each item of entry data, so the same function key
The FK can be shared by various businesses, there is no need to increase the number of key types, the time and effort required for key operations can be saved, entry speed can be increased, and entry errors can be prevented.

<Automatic Data Input at Input Step> For example, when entering record data for setting manufacturer code, product code, quantity, amount, etc. in an ordering process, there is a lot of common data regarding the manufacturer code and product code.

In this way, when there are common items between records, inputting these items one by one for each record results in a large loss in entry operations.

Therefore, in the present invention, it is possible to set whether or not input skipping is possible for each input item by specifying a parameter, and for input items for which input skipping is set to "enabled", when input skipping is performed, the previous record is This allows data for the same item to be automatically stored in memory.

Such skip conditions are set by specifying parameters in item #01 in the date-ail item table shown in Table 3-1.

FIG. 25 shows the operational flow at the time of data entry when input skipping is enabled.

As shown in Fig. 25, when each item is entered using the numeric keypad or TPR, the first step is to check whether it matches the input method set for the item (specified in item #13 or 14). It is determined in step 101 whether the

If they do not match, it is determined in step 102 whether or not input can be skipped, and if input cannot be skipped, re-input is naturally requested. If input can be skipped, it is determined in step 103 whether the input method matches the input method for the next item. That is, in step 103, it is determined whether or not the entry for the item to be skipped was not made, and the entry for the next item was skipped. If they still do not match, you will be asked to re-enter them. On the other hand, if the input method matches the input method for the next item, in step 104, the corresponding item of the previous input data (the item to be skipped) is read and input editing, various checks, and memory editing are performed. Then, set it to the buffer position.

Then, in the next step 105, the edited data regarding the skip item is set in the buffer as input data. Note that if the input methods match from the beginning in step 101, editing of the input data, etc. will be performed in step 105, regardless of whether skipping is "possible" or "impossible". In this flow, when input of all items is completed in step 106, the input data on the buffer is set as one record in the data memory in step 107, and data entry of the next record is started.

If such a skip input method is adopted, common data can be skipped directly and inputted to the next item, which greatly reduces the input effort and contributes to speeding up input operations and preventing input errors.

<Automatic addition function of business classification code> With data terminal machine, inventory work, ordering work,
When performing various data entry operations such as inventory operations, a task classification code representing the type thereof is automatically written into a data memory. The timing to write this code is when the data entry business key is pressed.

This code allows the host machine to easily determine the data type when the host machine receives and processes data entered using the business classification code.

The number of digits and contents of the business classification code are set in the setting mode.

For this reason, when performing various data entries with a data terminal machine, it is possible to set whether or not to write a business classification code representing the type of data entry business into the data memory.
When writing, the number of digits (length) can be set arbitrarily.

The contents of the business classification code can be arbitrarily set for each data entry business by a set number of digits. Then, when the data entry business key is pressed, the corresponding business classification code is automatically added to the data memory.

By using this function, a plurality of different types of entry data can be mixed and stored in the data memory.

(1) How to set the business classification code (a) Setting the number of digits for the business classification code If you do not need the automatic addition function of the business classification code, set "0".
Set any one digit number from "1 to 8" as necessary.

(b) Setting the business classification code The business classification code is set by specifying a code that clearly represents the content of the business within the number of digits set in (a) above.

(2) Processing method (execution mode) The processing flow of the above business classification code is shown in Figure 26.

Now, when one of the data entry jobs is selected in step 101, it is determined in step 102 whether or not there is a business category code, and if there is a business category code, the corresponding business category code is set in the memory in step 103. . Therefore, at this stage, the business classification code will be automatically added to the beginning of the data to be entered in the data entry business below.

Next, in step 104, data related to the business is sequentially input, and the entered data is set in the memory in units of records. The data entry in step 104 will be executed until it is determined in step 105 that the data entry has ended.

Also, if no business classification code is specified, step 103 is skipped and step 1 is entered.
Data entry by 04 is performed.

When the data entry for the job is completed, the next job, for example, the data output job to the host machine, is started.

When this data output task is specified in step 106, the above-mentioned transmission function
In step 107, the entry data stored in the data memory is output to the host machine.
If a business classification code is set, the business classification code at the beginning of the entry data will be output as is when outputting this data.
This allows the host machine to easily make business decisions regarding input data, which is advantageous in terms of data organization.

When the data output task is completed, memory clear is specified in step 108, and the data on the data memory is cleared in step 109.

When this series of processing is completed, step 1
The power is turned off at 10.

<Scroll-up function for display data> There are several types of data entry operations (ordering, inventory, etc.), and each one has a different number of items, data types, entry methods, and display methods. Therefore, depending on the display screen format, scrolling up may not be possible. Alternatively, in order to avoid making the screen difficult to view, it may be better to delete the data that has been entered.

Furthermore, the range and lines that are scrolled up vary depending on the display screen format. In this way, the purpose is to make the scroll up function versatile by switching it with parameters so that it can correspond to any display screen.

FIG. 27 shows an example of a display when input data is not scrolled up in an ordering process, and FIG. 28 shows an example of a display when input data is sequentially scrolled up in an inventory process.

In the display example shown in Fig. 27, “Hatsuchiyuugyoumu”, “Shiyouhincode”, “Yobi”, “Kubun” are displayed.
,
The guide texts “Tangka” and “Suuriyou” are displayed permanently, and the data is product code D ₁ ,
Day of the week D ₂ , category D ₃ , unit price D ₄ , and quantity D ₅ are input in this order, and when one input of these data D ₁ to D ₅ is completed, the area of these data D ₁ to _{D 5} is displayed on the display screen. Cleared from above.

In the display example shown in Figure 28, “Zykogiyouum”
is the second line, “Shiyouhin code”, “Thangka”,
"SUURIYO" is fixedly displayed on the third line, and the fourth to eighth lines are reserved as input data display lines.

Data is product code Dn, unit price Dm, quantity Dl
These data Dn, entered in the following order:
Dm and Dl are displayed on the bottom line (eighth line).

Then, the previously input data Dn _-1 , Dm _-1 ,
Dl _-1 is the 7th line, the data input before the previous time
Dn _-2 , Dm _-2 , Dl _-2 are 1 as shown in the 6th line.
Displayed by scrolling up line by line.

Such a scroll up function is specified in program setup mode and executed in run mode.

Figure 29 shows the program setting flow in the third step.
Figure 0 shows the operational flow during execution.

First, the setting flow will be explained with reference to FIG.

As shown in Figure 29, when the power is turned on,
In step 101, it is determined whether or not the current mode is execution mode, and if the setting mode is not execution mode, then in step 102, the first JOB #4301 among JOB #4301 to 4307 for specifying the scroll up method is displayed on the numeric keypad. The number is set.

Table 13 shows the settings for this JOB #4301.

As is clear from Table 13, the item # related to scroll up is "09", so in step 103 the function key FK1 is pressed and in step 104 "09" is entered using the numeric keypad.

Then, in step 105, press the function key.
When FK1 is pressed down again, at step 106,
The previous settings will be displayed. Then, in step 107, "n ₁ , n ₂ , n ₃ " are entered using the ten keys. Here, n ₁ is the number of lines to move, one line at a time,
The number of lines to scroll up is 2 lines at a time.
n ₂ is the top line of the scroll up area,
n ₃ indicates the lowest row. In the setting example shown in FIG. 28, n ₁ =1, n ₂ =4, and n ₃ =8.

When setting to not scroll up,
Let “0, 0, 0” be the set number.

After setting this number, press down the function key FK2 in step 108, and proceed to steps 109, 110,
Check the range of n ₁ , n ₂ , n ₃ set in step 111 (in this case, the number of displayed lines is "8"), and if there is no error, proceed to step 112.
In this step, n ₁ , n ₂ , and n ₃ are set in the memory of the parameter area.

The above settings are for JOB #4301 to 4307.
A total of 7 types of data entry tasks can be performed, and settings can be made for each data entry task.

Next, the operation flow in the execution mode will be explained with reference to FIG.

Now, in the execution mode, when a data entry job and its job number are specified in step 201, data entry is performed using the numeric keypad or TPR in step 202 or 203.
In the case of input using the numeric keypad, the end key is pressed in step 204 after inputting the data. In step 205, it is determined whether all of the input items specified in item #06 shown in Table 13 have been input, and 1.
Sequential data input is performed until the data input for the set is completed.

When one set of data input is completed, the entry data is set in the memory in step 206, and in step 207, the setting parameters of item #9 of the relevant JOB# are read, and it is determined whether or not to scroll up. In this case, the display is scrolled up according to the numbers n ₁ , n ₂ , and n ₃ .

Step 2 determines whether data entry is completed or not.
If the data entry is not completed as determined in step 08, the above operation steps are repeated, and when the data entry is completed, the process moves to the next necessary operation flow.

The guide message on the display screen is the 13th
As shown in the table, settings can be made in items #1 to #3.

<Automatic transmission selection function> Conventionally, when transmitting data, a transmission key or the like was provided and the transmission was started by pressing the key. However, in machines with a limited number of keys, there is a possibility that a send key may not be provided or that the send key may be pressed by mistake. In addition, the procedure of connecting the cable and then pressing the send key was difficult for those who are inexperienced or have limited knowledge to understand the operation.

Therefore, the present invention solves the above problems by making it possible to perform transmission simply by connecting a cable. Therefore, if the send key is set, sending is performed by pressing the key, and if the send key is not set, automatic sending is performed by cable connection, so it can be switched by setting. .

In other words, (a) when a transmission cable is connected to perform transmission work to output entered data to a back-processing machine, transmission can be started automatically, and (b) transmission work key If the key is set, transmission can be started by pressing that key, and methods (a) and (b) can be freely selected.

Regarding the sending task, perform the following parameter settings in the program setting mode.

(a) Parameter settings (1) Automatic transmission or manual transmission using a key?

Specify "00" for automatic transmission and key code "01-20" for manual transmission.

(2) Data output method specification There are data output methods shown in Table 17 below, and only one can be specified.

(3) Designation of data output normal completion determination (according to Table 18) This designation is the data output method designation.
Valid when GP4BTS (two consecutive inverted transmissions), GP8BTS, or standard non-procedure is specified.

(b) Execution mode Figure 31 shows a schematic flow during transmission. Third
As shown in Figure 1, when performing output work after data entry is completed in step 101,
At step 102, the presence or absence of a transmission key is first determined. If a transmission key is designated, a key input is awaited, and at step 103 it is determined whether the input key is a transmission key.

If the send key is pressed correctly, it is determined in step 104 whether or not the connection cable to the host machine is connected. If no transmission key is specified, in other words, if automatic transmission is specified, step 102 directly skips to step 104, and cable connection is determined.

Once the cable connection is confirmed, data is sent to the host machine.

With the above configuration, either automatic transmission or manual transmission can be selected according to the user's request, and in the case of automatic transmission, the transmission key can be omitted and the transmission procedure can be simplified.
