Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic desktop calculator, and more particularly to an improvement in processing the number of items indicating the number of items to be processed.

[Conventional example] In recent years, electronic desktop calculators have become smaller and lighter, and they also come in a wide variety of functions.

Some of these electronic desktop calculators print the number of items corresponding to the number of items processed (for example, the number of times the r+j keys were pressed during the invoice aggregation process) along with the final processing results, or they can be used to print out the number of items on paper along with the final processing results, or to use the readout key to print the number of items on paper along with the final processing results. There is one in which the number of items is displayed on a dedicated display device each time.

[Problems to be Solved by the Invention] However, in electronic desktop calculators that print the number of items on paper together with the final results, it is difficult to know the number of items in real time, during aggregation of many slips, etc. The problem was that it was not possible.

Furthermore, in the case of an electronic desk calculator that displays information on a display device using the readout key, for example, when processing a specified number of slips, the totalization process can be performed while checking the number of slips and the numbers on the display device. However, since it is necessary to operate the readout key each time during the aggregation process, there is a problem in that it not only reduces work efficiency but also increases costs due to the display device dedicated to that item. .

This invention was made in view of the above-mentioned problems, and its purpose is to provide an electronic desktop calculator that can improve work efficiency by notifying the user with an alarm when a predetermined number of processing items has been reached. It is in.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides that when data or commands are input from a keyboard composed of multiple keys,
In an electronic desktop calculator that performs calculations, displays, and processes the number of items based on the data and instructions, stores the processed data in a storage device, and displays it on a display device, the item count value is calculated by the combination of the plurality of keys. was preset in a first register provided in a predetermined area of the storage device, the preset item count value was read out, and the number of processed items was counted from a second register provided in a predetermined area of the storage device. The number of items is read out, the contents of the first register and the contents of the second register are compared, and if the number of items is greater than or equal to the item count value, an alarm is issued.

[Example] Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a circuit block diagram of an electronic desktop calculator to which the present invention is applied. In the figure, 1 is a keyboard, and this keyboard 1 has read keys 1a shown in FIG.
Numeric keypad 1b, function key 1c, decimal point (DP
) When the key 1d or the like is pressed, data and instructions are output to the arithmetic control section 2.

Note that the reading key 1a may be a key other than roOJ, and if a dedicated key is provided, that key is used. The arithmetic control unit 2 is, for example, a one-chip CPU, and is equipped with a ROM that stores programs for various arithmetic controls. Note that this ROM stores a processing program for presetting and reading out the item count value of the present invention, reading out the number of items, and issuing an alarm when the number of items is greater than or equal to the item count value. Further, a RAM 2a is connected to the arithmetic control unit 2 for storing processed data, values necessary for the present invention, and the like. In this invention, a register IOC for presetting an item count value and a register IC for counting the number of items are provided in a predetermined area of the RAM 2a. Further, the arithmetic control section 2 outputs display data to the display control section 3 based on data and commands from the keyboard 1.The display control section 3 performs a predetermined display (for example, calculation processing) based on the input data.

Display of the number of items) is performed on the display device 4, and a display device exclusively for the number of items! ! 5 is provided, the number of items is displayed on the display device 5.

Next, the operation of the electronic desktop calculator with the above configuration will be explained based on the flowcharts of FIGS. 2 and 3.

First, the user of the electronic desk calculator presets the item count value according to the number of items to be processed and reads out the value or reads out the number of items as shown in the schematic diagram of FIG. That is, this corresponds to, for example, the item number readout key 1a and the numeric keypad 1 provided on the keyboard.
b, function key 1c and decimal point key 1d
It is done in combination with. The item count value is set using the combination of the numeric keypad 1b, decimal point key 1d, and readout key 1a, and the number of items is read out using the combination of the function key 1c and the readout key 1a, and the preset item count is set. Reading of values is performed using a combination of decimal point key 1d and readout key 1a.

Next, the processing based on the above combination is executed by the read processing routine shown in FIG. In this routine, preprocessing is first performed (step 5T1), in which initial settings such as clearing the register CC and register IC, and various processes necessary for item counting are executed.

Next, it is determined whether the decimal point key 1d is ON or not (
Step 5T2), if the decimal point key 1d is not pressed,
It is determined whether the T flag is set (
Step 5T3). It is assumed that this T flag is set in the arithmetic control unit 2 when a number is entered on the numeric keypad 1b, and is reset when a key other than the numeric keypad 1b is entered. Therefore, when the T flag is set and the read key 1a is pressed, the numerical value input by the numeric keypad 1b is stored in the register IOC as the item count value.

Read key 1a if T flag is not set
When is pressed, the number of items counted in the register IC is read out (step 5T5).On the other hand, when the decimal point key 1d is pressed and the read key 1a is pressed, the item count value preset in the register IOC is read out. is read out (step 5T6).

Next, when the item count value is preset by the above routine, the operation of counting items by operating the "+" and "-" function keys will be explained based on the flowchart of FIG.

First, preprocessing is performed (step 5TIO).

This preprocessing includes clearing the initial setting of the register IC that counts the number of items, resetting the NF flag (described later), and selecting a mode for up-counting or down-counting the number of items. continue,
It is determined whether or not the NF flag is set (step ST'11).The NF flag is set when the item count value preset in the register IOC matches the number of items counted in the register EC.
is set, and if they do not match, it is in the reset state. If this NF flag is not set,
In other words, if the number of calculations such as slips has not reached the set item count value, the register IC counts the number of items (step 5T13).
Next, it is determined whether the contents of the register IOC in which the item count value is preset is 0 (step 5T14). That is, if the item count value is preset to rOJ, the operation of the present invention is not executed. figure,
Return to other arithmetic processing routines, etc. If the preset item count value is a value other than "0", a comparison is made between register IOC and register IC (step 5T).
15) If they do not match, in step 5T13, the register IC counts the number of items for each calculation process. Then, when the contents of register IOC and the contents of register C match, the FN flag is set (step 5T16), and then step 5TI
Proceed to step 5T12 from I, and in the case of "+" key operation, increase the count of the number of items in the register IC,
In the case of "-" key operation, it is determined whether the mode key is (see M key in FIG. 6), which decreases the count of the number of items in the register IC, is ON (step 5T12), mode key 1e. If not pressed, an alarm will be issued. This alarm will be displayed on the display, for example, “ERR.
"OR" is displayed (step 5T17), and
This alarm may cause the display device to blink. If this mode key 1e is pressed, step 5T1
In step 3, the number of items is counted in the register IC up when the "r+" key is operated, and down when the "-" key is operated. That is, in calculation processing of slips, etc.

If you make a mistake in inputting a value, use the "+" or "-" key to correct the same value as the wrong value, and you can increase or decrease the number of items to always keep the value accurate. . Then, the process returns to other arithmetic processing routines and various processes are executed.

FIG. 5 is a flowchart showing a modification of the above embodiment. Note that step 5T20 in FIG. 1 is the same process as step 5TIO shown in FIG. 2, so the explanation will be omitted.

First, after the process in step 5T20, a comparison is made between the item number register IC and the item count value register IOC (step 5T21). When a user calculates a slip, etc.

Counting the number of items in the register IC is the register IOC
If the item count value is not equal to the preset item count value, it is determined whether the count in the register IC exceeds the preset value in the register IOC (step 5T22).

If the limit is exceeded, the display will show, for example, “ERRO
RJ is displayed (step 5T23). If it is not over, various processing is performed (step 5).
T24'), these various processes include register IC counting, arithmetic processing, and the like.

On the other hand, if the contents of the register IC and the contents of the register IOC match, the register IC can be changed by pressing the "+" key.
It is determined whether the mode key 1e for increasing the count of the number of items in the register IC and decreasing the count of the number of items in the register IC by operating the "-" key is ON (step 5T25). Here, if the mode key 1e is not pressed, an alarm is issued (step 5T).
23), this alarm is displayed as "ERROR" on the display device, for example. If this mode key 1e is pressed, the count of the register IC is set to "
It goes up when the "+" key is operated, and goes down when the "-" key is operated. In other words, if you make a mistake in inputting a value in the calculation process for a slip, etc., and correct the same value by operating the "+" or "-" key, you can always increase or decrease the number of items. You can keep it at an accurate value. Then, return to other calculation processing routines,
Various processes are executed.

[Effects of the Invention] As explained above, according to the present invention, an arbitrarily preset item count value and the number of items are compared,
If the number of items is greater than or equal to the item count value, a display device is used to issue an alarm, so the number of items can be displayed on the display device using an electronic desktop calculator that prints the final result on paper or a readout key. For example, in order to know whether the number of processed documents, etc., has reached a predetermined value, regardless of which electronic desktop calculator is used.

The user's work efficiency can be improved without having to check the number of slips and the current number of items one by one.
