[Registration mode]

By setting the mode switch MS2 to "Register", the contents of the memory for storing cumulative income by expense item 1, total income 1, cumulative expenditure by expense item 1, and expenditure total 1 are stored, respectively. It is added to the contents of the memory for storing the cumulative expenditure by expense item 2 and the expenditure total 2.

In this embodiment, two sets of cumulative memories are provided because:
This is to store the daily cumulative total (or weekly cumulative total) and monthly cumulative total separately, but it goes without saying that the cumulative total memory may be one set (memory for storing monthly cumulative totals). However, as in this embodiment, if two sets of cumulative total memories are provided and the daily (or weekly) cumulative total and monthly cumulative total are stored separately, the daily (or weekly) cumulative total can be stored separately. It has the advantage that it can be read and checked at any time. Next, the block diagram of FIG. 3 and FIGS.
The configuration of this embodiment will be explained in more detail with reference to the flowchart in the figure.

Furthermore, F1, . ..., F4 is an RS type flip-flop for status control. [Power Off Mode] When the mode switch MSI is set to the "off" position, power supply to circuits other than memory M is cut off.

Incidentally, regardless of the setting state of the mode switch MSI, power is always supplied to the memory M from the power supply battery 2 unless the all clear key K^ is operated. [Calculator mode] When the mode switch MSI is set to the "Calculator" position, the power supply battery PSI starts supplying power to each circuit, the control circuit CUl operates, and the function key K
Desired calculations are executed based on the press of FN and data input using numerical keys KN.

The calculation is executed using the calculation registers x, Y, and W, and the calculation result is found in the register X. The calculation result obtained in this register X is displayed on the display DSP. [Household account book mode] When mode switch MS2 is set to the “household account book” position,
Power supply from the power supply battery PSI to each circuit is started, and the control circuit CU2 is activated to enable the household account book control circuit.

The operation will be explained below for each mode set by the mode switch MS2.

In the following explanation, ni indicates each step of the program. (Budget mode) When you press the inclusion key K^,
This is detected by the judgment circuit Jk (nl in the flowchart of FIG. 4), and the flip-flop FI is set at n2.

FI remains in the reset state unless the counting key K^ is pressed. o When you input the budget amount using the numeric key KN and then operate the inclusion key K^ and expense item key KIN.

It is detected at n3 that the expense key Kj has been operated, and the process proceeds to n4. n4 is a step of determining whether the operated expense item key is KO3 or K23. In budget mode, the expense keys KO1, KO2, KO3 are not operated, so in n4, the operation keys are essentially KI1, . . .
, K22 or K23. If the operation key is KI1, . . . , K22, the process proceeds to n5, sets the flip-flop F2, and then proceeds to n6. On the other hand, if the operation key is K23, the process immediately advances to n6. n6 is input buffer register B for storing item key code
This step is to transfer the contents of K to the second address register MAR. For example, if K12 is pressed, the address code that essentially specifies M5 is in BK and is transferred to MAR. Since the mode switch MS2 is in the budget mode setting state (SY), the process proceeds from n7 to n8.

In n8, the budget-related memory area MY specified address na
is input to the first address register PAR. As long as the remaining budget key is not pressed, flip-flop F3 is in the reset state, so the process goes from n9 to n16. Since the inclusion key K^ is pressed and FI is in the set state,
Proceed as n16→n17. The pressed expense item key is KI1,・
..., K22, F2 is set, so proceed as n17→n18 and perform "X+M→M".
This process adds the value just input (stored in register It is. This "X+M→M" processing step specifically consists of ml, . . . , m4 shown in the flowchart of FIG. First, the contents of register X are transferred to Y using ml. And in m2 “M→X”
I do. That is, the contents of the first address register PAR,
The storage contents of the area of memory M specified by the contents of second address register MAR are transferred to register X. Then, in m3, the input budget amount is added to the memory contents because it is executed as "x+Y→x", and the result of the addition is found in the register x. Then, "x→M" is performed in m4, and the addition result obtained in register X is input and stored in the original area. If you change the budget amount for each expense item in this way, the total budget will naturally change as well. Therefore, the total budget is calculated again in the next nl9. "2M→Mn" in nl9 is the process, specifically m5 in the flowchart in Figure 5,...
, m24. Register x now contains the addition result obtained in m3 above. This must be displayed again after the series of processing described below, but since register X will be used for calculations in the following steps, it must be temporarily stored in another register. m
5 is a step to perform the processing, and in m5, "X → W
'', the contents of register X are transferred to register W. m6, . . . , m14 are processing steps for changing the storage contents of each area of M13 and MD3, and since they are not relevant in the budget mode, they will be explained in the section explaining the operation in the cumulative mode below. .

m15,. ...The processing performed in 'm24 is MY40MY5
10...10 MY15, that is, ZM is calculated and the value of 2M is stored in MY16. First, m15 and second
The address register MAR contains the specified address “1” of MY15.
5". By executing "M→X" in m16, the storage contents of MY15 are transferred to register x.
This content is further transferred to register Y in the next m17.
In the next m1 3, “MAR-1=15-1=14→MAR
” to change the contents of MAR to the MY14 specified address “14”. Therefore, by executing "M→X" in ml9, the stored contents of MY14 are read out to register X. Therefore, at this point, register X has MY14.
The contents of register Y contain the contents of MY15.
Then, these additions are performed in m20, and the result of the addition is obtained in register X.

In the next m21, a determination of "MAR;4" is made, but since the content of MAR is 14, the process proceeds from m21 to m17.

Then, in m17, "X→Y" is performed, so the addition result of the contents of MY14 and MY15 is transferred to register Y.
By executing steps m18 and ml9, M
The contents of Y13 are read into register X. Therefore, m2
By performing “×10Y→×” at 0, MY is effectively
The contents of MY15, MY14, and MY13 are added, and the result is determined as X. Since MAR=13, the process returns to m17 again. The above process is repeated until MAR=4. In other words, if "MAR-1" in m18 becomes "5 - 1 = 4", then the next ml9, m20
Then, the addition of MY150, MY140, . Then, when proceeding from m20 to m21, “MAR=4
” is satisfied and the process proceeds to m22. The processing in m22 and m23 is to convert the 2× contained in the register X just obtained into MY
16 is input and stored. This means that the total budget has been revised. m24 first registers W
The contents temporarily stored in the register are returned to the register X. As a result, the budget amount for each expense item previously obtained in register X is displayed again. After completing nl9, n
20, n21, n22 are flip-flops F1, F2,
Reset F3 and complete the series of processing.

Returning to the beginning, the case where the determination result at n17 is NO will be explained.

The fact that F2 is in the IJ set state means that the operated key was K23, but there is no case where the main button count key is pressed and then K23 is pressed.

Therefore, being in FI (set state) and F2 (reset state) means that a key operation has been performed.
Therefore, in this case, the process immediately jumps to n20 and ends without any special processing. o Without pressing the inclusion key K^, immediately press the expense item key or expenditure total key Ki (i=11, 12...
・, 23) is pressed. The operations up to n16 are the same as described above.

It is determined in n16 whether the flip-flop FI is set or not, but if the key Ki is pressed without pressing the calculation key K^, the FI remains in the reset state, so n16
Proceed as 16→n15 and perform "M→×". That is, the storage contents of the area corresponding to the key Kj are displayed in the register X. In this way, F1, F2, at n20, n21, n22,
Reset F3 and complete the series of processing. That is, if the operated key Ki is one of KI1, ..., K22, the budget amount of the expense item corresponding to the operated key is explained and displayed, and if Ki is K23, the budget total is read out and displayed. The operation in budget mode is as described above.

[Cumulative total 1 mode] o When inputting the income or expenditure amount using the numeric key KN and then operating the inclusion key K^ and expense item key Ki.

The operations of n3, . . . , n6 are the same as in the budget mode described above.

In the total 1 mode, since the mode switch MS2 is in the cumulative 1 mode setting state (SI), n6 → n7 → n2
3→n24, and the address code specifying the MI area of the memory M is put into the first address register PAR.

That is, PAR is set to the memory area designation content related to cumulative 1. Since the flip-flop FI is in the set state, the process proceeds as n24→n16→n17. If i = 03, 23, it is a plot key operation, so proceed from n17 to n20,
Practically no special processing is performed. When i=01, 02 or 11,...,22, F. 2 is in the set state and proceeds to n18. As explained in the description of the budget mode, n18 is a step of adding the input income (or expenditure) amount to the storage contents of the designated area in MI. By executing this n16 step, the cumulative income by expense item is 1.
Since the sum of , ie, income total 1, or the sum of cumulative expenditure by expense item 1, ie, expenditure total 1, has changed, this value is recalculated in nl9 and input and stored in M13 or MI16. This process will be explained with reference to the flowchart in FIG. At m5,
The numerical value stored in register X is transferred to register W and temporarily stored.

Extract the contents of M12 to X using m6 and m7. This content is m
8, it is transferred to register Y. Then, the contents of MI1 are read into register X at m9 and ml0. mll's "X+Y
→X", the contents of MII and the contents of M12 are added, and the result is found in register X. And m13,m
In step 14, add the contents of this MII and the contents of M12 to M
13 is input and stored. As a result, the income total 1 is revised. m15, . . . , m24 are steps for correcting the expenditure total 1 (MIII+MI120...10M122) as described above. In the above manner, the addition to the cumulative total 1 and the correction of the total of the cumulative total 1 are performed.

o When the expense item key, income total key, or expenditure total key Kj is pressed without pressing the inclusion key K^.

If you press the key Ki without pressing the calculation key K^, n3 →
n4 (→n5) → n6 → n7 → n23 → n24 → n16
→n15 and performs "M→X" to extract and display the memory contents of the designated area.

The operation in the total 1 mode is as described above.

(Total 2 mode) Basically, the same operation as in the cumulative 1 mode is performed.

Mode switch MS2 is set to a total of 2 modes (Sro)
Since it detects that it is in n7→n23→n25→n
26, and at n26, the memory area MO specified address nc
is input to the first address register PAR. Therefore, M
O' will be included or proposed. (
Registration mode) Switch the mode switch MS2 to the registration mode setting state (ST).

The moment the mode switch MS2 is switched to ST, the one-shot signal generation circuit Q generates the one-shot signal QT. This signal QT is detected by n27, and n26
,..., Through the processing up to n37, income by expense item (
The contents of the cumulative total 1, income total 1, and expenditure total 1 storage area are added to the contents of the revenue (and expenditure) cumulative total 2, income total 2, and expenditure total 2 storage area for each expense item. n28, n2
MI16 is specified at 9, and its contents are read into register x at n30. The contents of register X are transferred to register Y at n31 in preparation for the next addition. n32, n3
3, the contents of MO16 are exported to register X. Therefore, n
By performing "X+Y→X" in step 34, the contents of MI16 and the contents of MD16 are added, and the result is found in register X. This result is input to Mlo 16 at n35. This process is repeated until MAR=0. That is, "MAR-1" is performed at n36, and the designated address of M is changed from 16 to 15. The process proceeds from n37 to n29 until MAR=0. MO the specified area of M with n29
Return to MI. Therefore, the memory specified area at this time is MI
It's now 15. Below, with the same operation as above, MI15
The contents of and the contents of MO15 are added, and the result is inputted to MO15 again. Repeat this and n34's "X+"
When "Y →
6 “MAR-1” executes 1-1=0 → MAR,
When the condition n37 is satisfied, the series of processing ends. This concludes the explanation of the operation in registration mode.

Next, the case of calculating the total income, total expenditure, current balance, and budget balance will be explained.

(When calculating total income) To obtain the total income, press the total income key Kc.

The press of this key Kc is detected at n38, and the process advances to n39 to set the flip-flop F4. M13 is designated with n41 and n43, and this content is read out and displayed in the register x with n44. The contents of register X are transferred to register Y in preparation for later addition. M03 the specified area with n46
The contents of this M row 3 are read out to the register x at n47. After that, by executing "x + Y → It is displayed on the PSP. n49
Then, the state of F4 is determined, and since F4 is a set state, the process proceeds to n49→n50 and the contents of register X are transferred to register W.

At this time, the contents of register X do not change at all. Therefore, the total budget will continue to be displayed. At n51, F4 is reset and the series of processing ends. The reason why the contents of register X are transferred to register W is to prepare for calculating the current amount, which will be described later. (When calculating total expenditures).

When counting the total, press the expenditure total key KD.

Pressing of this key Ko is detected at n30, and the process proceeds to n42.
MI16 in memory M is designated with n42 and n43, and its contents are read into register X with n44. Then, in n45, the contents of this register X are transferred to register Y. Change the area specification MO16 specification with n46, and change the contents of this MRO16 to n4
7 to read into register X. And in n48 “X+Y→X
”, the contents of MD16 (total expenditure 2) and M
Addition of the contents of I16 (total expenditure 1) is executed, and the result (total expenditure) is found in the register Y and displayed on the display unit DSP. Since F4 remains in the reset state, n4
9→Return to n38 and complete the series of processing. (When calculating the current amount) When calculating the current amount, operate the income total key Kc, the expenditure total key KD, and the current amount key KE in this order.

The operations executed upon pressing the income total key Kc and the expenditure total key Ko are as described above. Therefore, the contents stored in registers X and W at the time when the current high key KE is pressed are respectively register X: total expenditure register W: total income.

When the current high key KE is pressed, this is detected at n52 and the process proceeds to n53.

By performing "X→Y" in n53 and "W→X" in n54, the stored content of register X changes to the total income, and the stored content of register Y changes to the total expenditure. Therefore, in n55 “X-Y
→X", (total income - total expenditure), that is, the current amount is calculated and stored in register X. The current price determined in this register X is displayed on the display section DSP.
(When calculating the budget balance) When calculating the budget balance, set the mode switch MS2 to the budget mode setting state (SY), and press the budget remaining key K.
B, and the expense item key or expenditure total key Kj (i=11,...
, 22, 23).

When you press the budget remaining key KB, this is detected by n56 and n5
Proceed to step 7 and set flip-flop F3.

After that, press the expense item key or expenditure total key Ki, n3→n
4 (→n5)→n6, and input the expense item code into the second address register MAR. Since the budget mode is set, the process proceeds in the order of n6→n7→n8, and the MY area designation address field is entered into the first address register PAR. next n9
The state of the flip-flop F3 is determined at step 1, but since F3 is in the set state as described above, the process proceeds from n9 to nlo. At nlo, the storage contents of the specified area in MY (the area specified by operation key Ki) are read into register X. Then, at n11, the contents of register X are transferred to register Y. At n12, the designated area of the memory is changed to the MO area, and the contents of the designated area in this MO (the area designated by the operation key Ki) are read into the register X at the next n13. n1
At the time when the contents of register X and register Y are exchanged in step 4, the contents of register Or the total expenditure 2).

Therefore, by executing "x - Y → Budget balance) is calculated and found in register x. The budget balance for each expense item (or total budget balance) determined in this register X is displayed on the display unit DSP. This concludes the description of the first embodiment of the present invention.

Next, a second embodiment of the present invention will be described. The second embodiment is obtained by adding the following functions to the first embodiment.

[Functions added in the second embodiment] When the household account book mode is set, the household account book mode'
The keys used here (K^, ..., KF, Ki, K
Make the key sound only (N), and all other keys (
KFN) is pressed so that the key sound does not occur, and on the other hand, when the calculator mode is set, only the keys (KN, KFN) used in the calculator mode will generate the key sound. , other keys (K^,...
. , KF, Ki) is added in the second embodiment.

FIG. 6 is a block diagram showing the circuit configuration of parts that are changed or added in the second embodiment. Components corresponding to those in FIG. 3 are denoted by the same reference numerals, and their explanation will be omitted. In the figure, GI and G2 are turned on only when in household account book mode.
These are gate circuits that transmit key signals from keys K^, . . . , KF or key signals from key Ki, respectively.

Further, G3 is a gate circuit that is turned on only in the calculator mode and transmits a key signal from the function key KFN. And G4 is the gate circuit GI, G2, G
This is an OR gate whose inputs are the output signal of No. 3 and the key signal from the numerical key KN.

On the other hand, T is a T-type flip-flop which is repeatedly set and reset each time the key sound generation mode setting key KP is operated.

The output signal of the OR gate G4 and the set output signal of the T-type flip-flop T are applied to two inputs of an AND gate G5, and the output signal of the AND gate G5 is input to the drive circuit D of the speaker SP.

Further, LS and LC are diamond-shaped electrodes for "r" display and their counter electrodes, and DD is a display drive circuit.

This display drive circuit DD is controlled by the set output signal of the T-type flip-flop T, and when the output of T is "1", it supplies a lighting potential to the square electrode false, and the output of T is "0".
At this time, a non-lighting potential is supplied. In the figure, CCU is a calculator central control unit, and CKU is a household account book central control unit.

Next, the operation will be explained.

[Calculator mode]

o In calculator mode, operate KF to activate key sound generation mode.
When set to mode.

In the calculator mode, G3 is on, so when the numerical key KN and function key KFN are operated, an input signal is given to the OR gate G4.

On the other hand, the T-type flip-flop T is in a set state. Therefore, the output of OR gate G4 is passed through AND gate G5,
It is applied to the speaker drive circuit D, and a key sound is generated when the above KN and KFN are operated. On the other hand, since GI and G2 are off, even if K^, . Therefore, the above key operation is completely invalid and no key sound is generated. o
Key sound generation mode without operating KF in calculator mode'
When this setting is not made.

In this case, since the T-type flip-flop T is in the reset state and the AND gate G5 is off, no key sound is generated no matter which key is pressed.

[Household account book mode]

o In household account book mode, when KF is operated and set to key sound generation mode.

In household account book mode, GI and G2 are on, so when keys K^,..., KF, key Ki and numerical key KN are operated, an input signal is given to OR gate G4. .

On the other hand, the T-type flip-flop T is in a set state. Therefore, the output of OR gate G4 is given to speaker drive circuit D via AND gate G5, and the above KN, K^, .
..., a key sound is generated when operating KF or Ki.

On the other hand, since G3 is off, even if the function key KFN is operated, the calculator sequential control unit CUl
There is no input to G4 and no input to gate circuit G4. Therefore,
The above operation of the key KFN is completely invalid and no key fee is incurred. o Household account book mode' When key KF is not operated and key sound generation mode is not set. In this case, the T-type flip-flop T is in the reset state and the AND gate G5 is off, so no key sound is generated no matter which key is pressed.

This concludes the description of the second embodiment.

Next, a third embodiment of the present invention will be described.

The features of the third embodiment are as follows.

In the first embodiment described above, when the budget remaining key KB is operated, the budget balance is calculated and displayed, but in the third embodiment, when the budget remaining key KB is pressed, the budget balance is calculated and displayed. At the same time, calculate the budget balance and display it, as well as the budget by expense item (or budget total) of the cumulative expenditure by expense item 2 (or total expenditure 2)
The configuration is such that the ratio is also calculated and this ratio is also displayed.

FIG. 7 is a plan view showing the display section in the third embodiment, and S is the above-mentioned ratio display section.

The correspondence between the ratio of the cumulative expenditure by expense item 2 (or expenditure total 2) to the budget by expense item (or total budget) and the display mode in the ratio display section S is as shown in Table 1 below. FIG. 8 of Table 1 is a block diagram showing the circuit configuration of the part added in the third embodiment, and FIG. 9 is a flowchart showing the program of the part changed in the third embodiment.

Register x in FIG. 8 is the same as register X in FIG.

Z is a buffer register that stores a one-digit numerical value.
The input control circuit of the register Z has the function of inputting only the first digit of the integer part of the numerical value found in the register X into the register Z. On the other hand, S1, . . . , S4 are ratio display electrodes constituting the ratio display section S, and are provided to selectively display the information shown in Table 1 above.
DCZ is S1,...,S according to the contents of register Z.
This is a display selection circuit that supplies a lighting potential to a predetermined electrode in 4. Next, FIG. 9 will be explained.

In the third embodiment, the part "nlo,..., n14, n14'" in the flowchart of FIG.
It is changed to "m30, . . . m42" shown in the figure.

m30,.・, m35 is a ratio display control step, m
30, the budget amount for each expense item (or the total budget) is transferred from memory M to register X, and further transferred to register Y.

Then, in m32, the specified area of the memory M is set to the budget storage area M.
Switch from Y to cumulative 2 storage area MO', and output cumulative expenditure by item 2 (or expenditure total 2) to register X in m33. The contents of registers X and Y at this point are, respectively, register X: cumulative expenditure by expense item 2 (or expenditure total 2), register Y: budget amount by expense item (or budget total).

Then, in m34 and m35, "odd×4→X" and "X→Z" are executed. "X→Z" in m35 is a process for transferring the contents of the first digit of the integer part of register X to register Z. As is clear from the processing in m34 and m35 above, the correspondence between the ratio of cumulative expenditure by item 2 (or total expenditure 2) to the sub-item amount (or total budget) and the numerical value introduced in Register Z is as follows. It is as shown in Table 2. Table 2 The relationship between the contents of one register Z and the output of the decoder DCZ (ie, the ratio display electrode to which the lighting potential is supplied) is as shown in Table 3 below.

By the processing in Table 3 and above, the cumulative expenditure by expense item 2 (or total expenditure 2
) is displayed in the ratio display section S according to the ratio of the budget amount for each expense item (or the total budget).

The processing executed at m36, . . . , m42 is substantially the same as the processing executed at nlo, .

The budget amount by expense item (or budget total) is input into register Y in m36, m37, and m38, and the cumulative expenditure amount by expense item 2 (or expenditure total 2) is input into register X in m39 and m40. Then, in m41, the contents of register X and register Y are exchanged. At this point, the contents of registers X and Y are as follows: Register X: Budget amount 2 by expense item (or budget total) Register Y: Accumulated expenditure by expense item 2 (or Total expenditure 2).

Therefore, by executing "X-Y→X" in m42, the budget balance is found in register x and displayed on the display unit DSP. In this third embodiment, the ratio display electrode is S1.
, . The settings are as shown in the table, but the shape and number of ratio display electrodes, as well as the ratio of the cumulative expenditure 2 (or total expenditure 2) by expense item to the budget amount by expense item (or total budget), and the display in the ratio display section. It goes without saying that the correspondence between aspects can be set arbitrarily.

Other embodiments of the ratio display section will be described below. 10th,
FIG. 11 is a diagram showing another embodiment of the ratio display section. In Fig. 10A, each mouth is provided with 5 or 1 fixed electrode for ratio display to enable more detailed display.

In Figure 10 C, 2, and Tree, as the percentage approaches 100%, more detailed display is possible.

With this structure, the cumulative expenditure by expense item2
As (or expenditure total 2) approaches the budget for each expense item (or the total budget), the changes can be displayed in more detail, which is extremely effective for preventing budget overruns. Also,
The one shown in Fig. 10 is an improvement of the one shown in Fig. 10 (e).
It is characterized in that a thin cut is provided in the center of the arc portion of the electrode for displaying the percentage from 0% to 80%.

This notch makes it clear to the user that the percentage display segment from 0% to 80% is displaying twice the amount of the percentage display segment displayed at 90% and 100%. , to make the percentage display easier to understand. Furthermore, in Figure 10, the overall shape is 1
It is a phantom square. In FIG. 11, a display is made between the electrodes for displaying the ratio to indicate a division, and a display indicating the direction of increase is also made.

As a method of displaying this, the shape shown in the figure may be printed on the display body, or electrodes of the shape shown in the figure may be formed together with electrodes for ratio display, so that when the household account book mode is set, it is always displayed. A configuration may be adopted in which a lighting potential is supplied to this electrode. Note that since changing the drive circuit is easy for those skilled in the art, a description thereof will be omitted.

As explained above, according to the present invention, a plurality of memories are provided for storing budgets for each expense item and cumulative expenditures for each expense item, and the budget or expenditures can be selectively stored in the plurality of memories by operating a key. It is possible to store the amount of money or, conversely, to selectively read and display the contents of a plurality of memories.
