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

c Item #10] Specification of various information for items (a) Item length Specify the required length (digit length) for each item. However, C/D
Includes symbols such as check code, decimal point ",", sign 1±2, etc. 1 item classification code. The digit length specified here is allocated to the data registration memory.

(b) Display area Regarding the area for monitoring when using the numeric keypad manually or displaying the input contents when inputting using the barcode reader TPR,
Specify the number of lines (1 digit) and FT length.

(c) Item delimiter code Specifies whether or not to store a code representing the delimiter of each item when storing each input item in the data registration memory. When storing, specify the code (1 digit).

Note that the code designation is different for 4BIT and 8BIT.

(d) Manual termination key When inputting using the numeric keys, the key indicating the end of inputting an item is designated by a key code. When the key specified here is input, it is assumed that the input of the corresponding item has been completed.

(e) Calendar*11ft The calendar functions provided by the system include writing (initial registration items only) and reading (heading and detail items only).

You can specify whether these functions are present or not.

If you specify ``Yes,'' the contents should be changed to [Year, Month, Date J.

Specify only one of [hour, minute J, [year, month, day, day of the week, 1 hour, minute J].

(f) Specify whether or not TPR input is possible. Since manual input using the numeric keypad is always possible for any item, multiple manual input using the numeric keypad is required for items designated as TPR input-enabled.

[Item #II] Specification of various check methods (a) Month/Date check, etc. For "Month/Date", "Hour/Minute", "Monday/Sunday Hour/Minute" check, for example, OO≦Hour≦23.00≦Minute≦59 Perform such checks.

(b) Range check this fIl! J check, for example, checks whether the manually entered amount is within the range from the lower limit to the upper limit, so for example, 10 range tables (01-1 ( You can specify from 1).This check can be specified for one item by specifying other checks (for example, month/day check, etc.)
If there is no check, it is possible to check a maximum of five types, and in that case, perform "OR" for each type. Check only the effect digits, ignore the sign and decimal point.

Table 5 shows the above range table.

(C) Check/Dinot [C/D] Check This is a C/D check for human labor items. , a can be added to the beginning of the input items to perform a C/D check.

As weight, 11++ nt+ ns+ n4+
kJSl is the weight allocation method when n* is specified.
Shown in Figure 1.

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) Verification check with the 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 manual data value of the heading and detail items and the totalizer (for addition) [explained later] that the system has, and one example is 112
As shown in the figure.

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

If of the system totalizer that calculated the sum X+! (total value) is cleared when this check is completed.

The system totalizer will be described in detail in the section ``Using the System Totalizer'' below.

CD mask data search check This check is possible for heading and detail manual items, and when this check is specified in the input item, the process is as follows.

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

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

(f-2) Search from the first DA of the delay record group in the mask registration memory using the N specified input data key.

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

・Sounds a high-pitched long buzzer when an error occurs. Turn off the long buzzer with the CE key among the funkunjin keys and enter this item again.

・When ignoring After processing the input data, move on to inputting the next item.

(b) Display the MAXIO item on the liquid crystal display 11 among the items of master data when it is in the master registration memory. The displayed contents are referred to when manually inputting detail items.

- Specify the display area for each item of mask data (do this for each data entry) Specify the length of each line (1 digit, 1 digit) 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 1 θ, the editing specifications at the time of display are as follows.

°0°...No editing → Display the image in memory as is.

“1”: Preceding zeros are erased and only significant digits in memory are displayed.

°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 mask data are erased when the input of the final item of the heading and detail record is completed.

This mask data search check will be explained later in the <Master file function> section.

(g) Data registered check This check is possible only for detail input items, and when this check is specified in a manual item, the process is as follows.

Similar to the detail record memory search function, the input data (positive integer) is edited in the same manner as the memory format, and using this as a key, the data registration memory is searched from the beginning of the same detail record group that is currently being input.

(b) Displays the contents of the searched detail record when it has already been done manually, and sounds a high-pitched buzzer. The display is the same as the manual mountain face of Decheil currently being input. Editing during display is done as follows.

*Fixed digit items are displayed as images in memory.

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

* When the deletion key is pressed manually, the buzzer and displayed contents are erased, and the entire searched detail record on the data registration memory is filled with the specified special code (same as the memory clear code when deleting memory search). Again, this item will be manpower.

*When a key that is not deleted is entered Turn off the buzzer and the displayed content, and then manually enter this item again.

You can specify a key to delete or not to delete the searched detail record on the data registration memory.

(b) When the input data has not been completed, after processing the input data, it takes f more time to input the next item.

[Item #I2] Memory editing method etc. Although the designation method for the memory editing method differs depending on the type of heading, detail, and footing, here, the memory editing method for detail records shown in Table 3 will be mainly explained.

(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, no decimal point when specified as ``0''). With this specification, input data is edited based on the specified decimal point position. In this case, the overflow is cut and the shortage is filled with zeros. If there is no decimal point, edit with the right end as the decimal point.

Whether or not to store the decimal point position depends on the setting of the nostem parameter.

(2) 10° i Last digit deletion Delete the last digit (C/Did) of the manual data and store it right-aligned. Overflows are cut and missing parts are filled with zeros.

(3) "21" C/D addition Add the C/D value next to the last digit of the input data and store it right-aligned. In other words, "n" specifies the item number of the C/D table (nil to 6).

In this case as well, the overflow is cut and the shortage is filled with zeros.

(b) lit! Item addition (data synthesis) Other item addition is L type data synthesis, and is synthesized with manual data of other items (heading or detail).

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

(C) Use of system totalizers In this system, 1 [4 totalizers (14-digit integer part, 2-digit decimal part) are prepared, and the following usage methods are possible.

*Save input data.

*Add input data.

* Continue reading the system totalizer data.

* Check that the human data and the system totalizer value are equal.

* Check that the values of system totalizers are equal.

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

Usable range (+) Use in heading or detail record As shown in Figure 16 <a>, the total is a numeric keypad input item, and the input value is the sum of items 1 to n. An equality check is performed between the numeric keypad manual power value and the total value (added to the system totalizer when items 1 to n are manually powered) (see the section on total check). At this time, it is not possible to enter the total items manually from the system totalizer without using the numeric keypad.

(2) Use in detail record and footing record As shown in Figure 16 (b), when inputting the total of the manual input items in the detail record in the footing record, the total numeric key input value and Performs an equality check on the total value (added to the system totalizer when manually inputting items).

It is also possible to use the system totalizer manually without using the numeric keypad.

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

[item#! 3] Specifying the key manual method For detail records, four types of key manual methods can be set. There is only one type of heading and butting.

(a) Specifying the total number of digits However, the total number of digits here is the number of significant figures, and the decimal point °,
Does not include ° or signature.

(b) Number of decimal places If there are no maximum 2 digits or small losses, specify ``OO''.

(c) Human powered mote “0”: The number of digits is fixed and only positive integers can be input.

°−”, °, ° cannot be done manually.

“B... You can enter positive integers with various numbers of digits.

“-“Y°,” cannot be said by a person.

``2°...Positive and negative integers with various numbers of digits can be input, but ones with 1.2 decimal points cannot be entered manually.

“3゛...Positive real numbers of various numbers of digits can be entered, but −° cannot be entered manually.

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

(d) Omit the number on the numeric keypad Specify whether or not the number on the numeric keypad can be omitted, and if it can be omitted, whether it is regarded as an input of "O" or "B". If omitting the number is specified, only the end key can be input (described in detail later).

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

(b) Left-justification of input data The manually entered data is left-justified, and the missing part is later filled in with a filler code (one digit among HEXX "0° to °9").

(c) Start digit misplaced 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 human power item 2.

As shown in Figure 14, in input item 2, the classification code is entered into the top three digits and the product code is entered into the bottom five digits.This time, the five-digit number corresponding to the product code is entered manually. If input, this product coat has been classified +1i times =! - is combined with -do. In this case, the current data (
The first digit P to be replaced with the product code) is c as described below.
Item #11] is specified in the key manual method.

The data (classification code and product code) synthesized in this way is input into the input field °2'' of the current record.

Such data composition has the effect of making the input operation of partially common data extremely commercial.

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

When data entry for an l record is started using the numeric keypad or TPH, the input data is displayed on the display, and in step +01, it is determined whether or not to combine it with the previous input data. , the specified pond is edited in step +02. "Y
ES'', 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 displayed in step 104, and the composite data can be confirmed.

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 done in step 1
The process is repeated until it is determined in step 07 whether data entry has been made up to the last item, and after completing one record manually, the input data is set in the data memory in step 108, and the process moves to data entry of the next record.

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 on the input data can be performed on the computer where the input data was edited.

[Item #14.15] 1” Specify the PR method If input is to be completed with one scan, specify the manual method in item #14. If the input is to be completed manually with multiple scans, specify the manual method in item #15. °ru

Basically, the specification is based on the following TPR manual table (first
This is done by specifying the number (JOB#) in Table 2).

Specifically, with reference to Table 12, the number of digits to be read, the starting digit position of valid data, the presence or absence of the valid data length 0 division code, the classification code if it is present, and the barcode type (NW
-7, JAN (8,13 digits).

2 out or 5. jN'rlEJILEAVE
D 2 outof5), check digit table number.

Specify decimal values such as "-', "+", +,".

For multiple scans, specify the end conditions for the entry.

The input termination conditions are: * When a TPR input other than the specified number of read digits (1 class) is made, or when there is key input.

*0-9. “, When there was TPR manpower other than ° (“−
° is considered as negative data, other times as positive data. ).

<C/D calculation method for data including symbols such as decimal points> In order 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, C/D check is performed to prevent numeric input errors.

However, C/D calculations can usually only handle integers. However, when the data includes a decimal point or + or - symbols, C/D calculation cannot be performed as is. Therefore, numbers from 0 to 99 are set in advance for the decimal point and + and - symbols, and when performing C/D calculations, the set numbers can be used instead of the symbols. It is. By doing so, it is possible to calculate C/D for data including symbols other than numbers.

The designation method in this case is not shown in Table 12.
On the large input table, it is shown in item #-03''.

In this item # “03”, the type of barcode mentioned above,
In addition to specifying the type of C/D, a “-” symbol.

Assign any two-digit value 00 to 99 to the °+" symbol and the decimal point symbol ",". In other words, convert these symbols to appropriate values. If you do this, The C/D check can be performed on all real numbers including integers with plus and minus signs and decimal points.

Now, a detailed explanation will be given according to the operational flow of the C/D check shown in FIG.

For example, "-1234,
67” is manually performed, C/D for this manual item.
It is determined in step 102 whether or not to perform the check;
When performing a C/D check, in step 103 “
−”, ° ” the desomal values specified for these,
For example, "11".

Replace with 31°.

Therefore, the C/D calculation in step 104 is “
+1+2343167°, and the calculation result and C/D are checked for equality in step +06. If they are not equal, an error will be displayed.

In the above example, we will explain the case where "+", "-゛, decimal point", and ° are included.1. However, the above idea can be extended to other symbols, such as °\°, which represents the Japanese yen.

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

Hereinafter, the main Falili will be explained by function.

<Setting data error check> In order to execute M1-type business programs, that is, multiple types of application specifications, from a single program, 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 some reason such as noise or malfunction, 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, conventionally, for the program section,
Checks such as sum checks are performed, but no checks are performed on the parameter section.

The present invention prevents equipment malfunctions by checking the parameter section of the river fish in the same way as the program section.

This method of checking parameter (2) is characteristically shown in FIG.

During 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.
Be manipulated.

The P-OFF routine FOR is executed in response to the OFF operation of the power switch (the parameter setting end key may also be turned ON).

In this POfl, 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 funk engine key to start the application program is pressed, the program starts as shown in FIG. - After determining whether or not the data is loaded, a sum check is performed in the next step.

In this sum check, a sum check is performed on both the program and the aforementioned parameters.

Therefore, if not only the program but also the parameter section is corrupted due to some reason,
A sum check error is displayed and the program stops running. In this case, in parameter setting mode,
Once again, the setting parameters can be checked as necessary, for example, the stored setting parameters can be sequentially displayed and compared with the setting data table.

In this way, you can check not only the program section but also the parameter section, so you can discover any irregularities in the setting parameters before they occur, and they are always correct: i1. It becomes possible to execute the Walk program.

<Master file function> The master file function according to the present invention is capable of (a) allowing the data terminal machine to have multiple types of data as a master file that can be referenced when performing entry work, and (b) allowing the data terminal to store the entered data. You can use the key to search for master files and display related data, (c) you can freely configure the master file structure, and (d)
You can select the data necessary 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,
It can also be corrected manually, and consists of a series of functions that (g) erase the master data displayed for reference when the entry of data for an I record is completed.

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 you time and allows you to manage (d)N data in files.
(e) Search the master file as necessary.

It has the advantages of being able to modify and (to) display master data in a free format.

(a) Structure of the master file The structure of the master file is as shown in Figure 18, starting with the number indicating the starting digit of the first code of the master file.
Defined as a set of records of the same length.

Each record has key data MK as shown in FIG.
Skip the starting digit of ey and start with the data, key data MKe
y, and when searching for a master file, the setting is such that a key search can be performed using key data MKey.

The master file settings are made according to Tables 13 and 14.

The items constituting each record are from the 1st item to the 10th item, and the item length of each item specifies the starting digit of one item.

In addition, the display method when collating master data is JO
Display line Jli of each item 1 in item #21 of B#4301,
It is set by specifying the display start digit di and digit length old. Moreover, the editing method at the time of display is set according to Table 15.

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

(b) Creation of 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 Figure 21, when master file reception job A is selected in job selection, the main unit is connected to the host machine via a parallel or norial reception cable, and reading starts when the receive key is pressed. However, it is possible to create a master file by storing it in the memory area reserved for master files in this device. For example, there can be multiple N master files for each business such as ordering and inventory work. ! can be created.

Furthermore, in FIG. 21, when master file modification task B is selected, manual modification can be performed while monitoring the data of the master file once created.

(C) Master data search check at data entry In Figure 21, the mask data search check is performed when data entry C is selected for business selection and the business content of data entry (ordering, inventory, etc.) is specified. This is done as follows. However, this mask data search check is only one of the check methods in Table 3-1.
This is performed only when the mask data search check code ``OO'' is specified.

The checking method in this case is as shown in Fig. 21.
The following methods C-1 and C-11 are possible.

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

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

(+-2) How to set parameters for master file configuration Set the mode switch to setting mode and perform the settings as follows.

FIG. 22 shows details of the C-1 method.

At step 501, when the data for 1 ref-1 is input, the funkun key PK is pressed, and at step 502
In step 503, it is determined whether or not to perform a search check on the master data, and in step 503, whether or not the key data RKey in the entry data matches the key data MKey in the master file is checked for each record. Search for.

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

The pond item is entered by referring to the display contents of this master file record.

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

In addition, in the above search, if there is no matching item, an error is generated or ignored according to the set parameters.

(2) C-11 method In this case, first, in step 406 of FIG. 21, the second record of the master file is displayed.

If the data is not the intended one, press forward function key FW to display the second record. In this way, the master file records are monitored one after another, and when the desired data is displayed, a predetermined function key PK is pressed in step 407 to read the key data MK Cy of the master file record (step 408). , this key data MKcy is memorized 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. Note that for other items as well, the data of the corresponding item in the master file record may be read as is and stored in memory, similar to the reading of MKey.

When the data entry for one record is completed, the same entry operation (including verification) as described above may be continued for the next record.
