Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the calculation of a charge for sharing a charge such as food and drink with a group.

[0002]

2. Description of the Related Art When a group eats and drinks, it is widely practiced that members of the group pay equally for eating and drinking. This is the so-called split bill. In the case of split billing, the amount to be shared for each member is determined by dividing the fee for eating and drinking etc. by the members of the group. In this case, the sharing amount for each member is determined by performing mental arithmetic or operating a small calculator suitable for carrying.

[0003] When making a split bill, there is a case where it is desired to make the sharing amount different in consideration of differences in income, ability to pay, etc. among the members. For example, when a member of society and a student eat and drink in a group, it can be seen that the member of society pays more than the student.

[0004]

However, in the case where the sharing amount is made different, it is not always necessary to simply perform the division, so that it is very difficult to determine the sharing amount.

Accordingly, an object of the present invention is to provide a sharing amount determination device or the like that can easily determine the sharing amount when performing splitting with different sharing amounts.

[0006]

SUMMARY OF THE INVENTION The present invention relates to a sharing amount determining apparatus for determining the sharing of the charge of a group consisting of a plurality of groups by equally setting the sharing amounts of the members of each group.

[0007] The present invention comprises a sharing target amount determining means, a group number recording means, a sharing amount determining means, and a group sharing amount calculating means according to the present invention.

[0008] The allocation target amount determining means determines the allocation target amount to be allocated in the fee. The group number recording means records the number of members of each group. The sharing amount determination means determines the sharing amounts of the members of each group except for a predetermined group based on the input parameters. The group sharing amount calculating means calculates the sharing amount of the members of each group based on the sharing amount, the sharing target amount, and the number of members of each group determined by the sharing amount determining means.

According to the present invention, by inputting the parameters, the sharing amount determining means determines the sharing amounts of the members of each group, and based on these, the group sharing amount calculating means determines each group. Calculate the share of the members. Therefore, by inputting the parameters, it is easy to make a split bill with the share allotted differently for each group.

[0010] In particular, if the parameters are determined according to the amount of rotation of the operation element that can be rotated and pressed, it is possible to make a split bill with a different share for each group simply by rotating the operation element.

In addition, the mobile phone has many other functions. For example, imaging by a camera, wireless communication by Bluetooth or the like, listening and recording of music, and the like are also possible. However, since these functions are not directly related to the embodiment of the present invention, they are not shown in FIG.

FIG. 4 is a block diagram showing the configuration of the sharing amount determination device according to the embodiment of the present invention. The sharing amount determination device includes a total amount input unit 12, a donation input unit 14, a group number input unit 16, a parameter input unit 18, a group number recording unit 22, a sharing target amount determination unit 24, a sharing amount determination unit 26,
It includes a group sharing amount calculation unit 28 and a remainder calculation unit 30.

The sharing amount determination device is a device for determining the sharing of the charge of a group consisting of a plurality of groups by equally assigning the sharing amounts of the members of each group. For example, a group of 10 eats and drinks together, and the total price is 52,348.
Suppose it was a circle. Also, suppose that someone donated 10,000 yen to this group of ten people. In addition, the group of 10 is group A, which has excellent solvency (the number of members: 5).
And group B (composition: 5)
People). Here, the sharing amount per group A and the sharing amount per group B are determined by the sharing amount determination device. Further, the sharing amount determination device is configured using each unit of the mobile phone 1.

The total amount input unit 12 is for inputting a charge to be borne by the group as a whole. Donation input unit 14
Is for inputting the amount to be deducted from the fee to be borne by the group as a whole. For example, when money is donated to the group, the amount of the donated money is the amount to be deducted. Of course, in addition to donations, there are various factors such as having a discount ticket. The group number input section 16 is for inputting the number of members of each group constituting the group.

An example of the input of the total amount input unit 12, the donation input unit 14, and the group number input unit 16 will be described with reference to FIG. FIG. 5 shows a screen 102 on which an input result is displayed on the display 2 of the mobile phone 1. Numeric keypad 4
By inputting the total amount, donation, group A, and group B in the box on the right side according to c, an input result as shown in FIG. 5 is displayed.

The parameter input section 18 is for inputting parameters used for the allocation target amount determination section 24. The parameter input unit 18 rotates the jog dial 3 upward (1), (2) downward,
) Is determined and output in accordance with the rotation amount of the rotation operation such as the rotation operation described above. The parameters will be described later.

The number-of-groups recording unit 22 records the number of people of each group constituting the group based on the input contents of the group number input unit 16. FIG. 6 shows an example of the recorded contents of the group number recording section 22. It is recorded that group A has 5 members and group B has 5 members.

The allocation target amount determination unit 24 determines an allocation target amount to be allocated in the fee. That is, the amount obtained by subtracting the deduction amount (due to donation or the like) from the fee is the amount to be shared. Therefore, the allocation target amount determination unit 24 determines the total amount input unit 12
By subtracting the input contents of the donation input unit 14 from the input contents of the above, the share target amount is obtained. In the above example, the share target amount is 52,348 yen-10,000 yen = 42,348 yen. In the case where there is no donation or the like, the fee becomes the shareable amount as it is.

The sharing amount determination unit 26 determines the sharing amounts of the members of each group except for a predetermined group based on the input parameters. For example, if one predetermined group is a B group, the share of the A group is determined.
A method of determining the share of Group A will be described with reference to FIG.

First, referring to FIG. 7A, a value obtained by dividing the amount to be shared by the number of people in the group is defined as an initial amount of sharing M. However, the share target amount may not be divisible by the number of people in the group, and it is troublesome to determine the share amount in units of one yen. Therefore, the value is rounded as appropriate by rounding up, rounding down, rounding off, and the like. As a result, a small difference appears between the members of the A group and the B group, so that the initial share of the A group is Ma and the initial share of the B group is Mb. Specifically, Ma is a value obtained by rounding the value of M. Mb
Is a value obtained by subtracting the total of the initial allocation amounts of the group A from the allocation target amount and dividing the remainder by the number of members of the group B, and then rounding. Such an initial burden amount is calculated by the group allocation amount calculation unit 28, and the allocation amount determination unit 26 receives the calculated initial burden amount.

In the above example, if the amount to be shared (42,348 yen) is divided by the number of people in the group (10 people) and rounded up to the tens place,
The initial share M is 42,348 / 10 = 4234.8 → 4,300 yen. This is defined as the initial allocation amount Ma of the A group. Also,
Group B's initial share Mb is (42,348−4,300 × 5 (A
Group number)) / 5 (Group B number) = 4169.6
→ ¥ 4200.

Referring to FIG. 7 (b), sharing amount determination unit 26
Is the sum of Ma = 4,300 yen and the predetermined unit contribution amount Sa.
The new share of the group. Here, the unit burden S
a = 100 yen. In the above example, the new share of group A is Ma + Sa = 4,400 yen. At this time, the new share of group B decreases. As described above, if the addition of the unit burden amount Sa is repeatedly performed n times, FIG.
As shown in (c), the new share of Group A is M
a + n × Sa. Here, n × Sa is called an adjustment amount, and n is called a coefficient. The new share of the A group is obtained by adding the adjustment amount n × Sa to the initial share Ma. Adjustment amount nx
Sa is a value obtained by multiplying the unit burden amount Sa by the coefficient n.

In this way, the share of the group A is determined. In FIG. 7, the new share of the group A is continuously increased, but the new share of the group A may be reduced by reducing the unit burden Sa. A
The amount by which the new share of the group is added or subtracted from the initial share Ma is determined by a parameter which the parameter input unit 18 provides to the share determination unit 26.

For example, a parameter given by the parameter input section 18 to the share determination section 26 can be a coefficient n. The parameter input unit 18 increases n by 1 in response to the operation of turning the jog dial 3 upward (1) after setting n = 0 first, and rotating the jog dial 3 downward (2).
In response to the above operation, the parameter n may be determined so as to decrease n by 1, and the parameter n may be provided to the sharing amount determination unit 26.

Ma = 4,300 yen and jog dial 3
It is assumed that (1) the operation of rotating up is performed three times, and (2) the operation of rotating down is performed twice. Then, n = 3-2 = 1. n is given as a parameter to the sharing amount determination unit 26, and the new sharing amount of the A group is Ma + n × Sa = 4,300 + 1 × 100 = 4,400 yen.

As described above, it is preferable that the share of the group A is determined. However, the share of the group A may be represented by the share of the group B, which is a predetermined group. Mathematically, this is equivalent to eliminating the share of Group A.

For example, the allocation amount of the group A is represented as B = the allocation amount of the group A = the allocation amount of the group B × 1.2.
It may be determined as a value obtained by multiplying the share of the group by the premium rate. Further, the allocation amount of the A group may be determined as the addition amount of the allocation amount of the B group, such as the allocation amount of the A group = the allocation amount of the B group + 1000. Note that the premium rate and the added amount may be determined according to the parameters provided by the parameter input unit 18. For example, the premium rate is increased by 0.01 (additional amount is increased by 100) based on the operation of rotating the jog dial 3 on (1).
Then, the premium rate may be reduced by 0.01 (additional amount is reduced by 100) based on the operation of (2) rotating downward.

As described above, "determination of the shared amount" is a concept including determination of the value and erasing of the shared amount.

The group sharing amount calculation unit 28 calculates the sharing amount of the members of each group based on the sharing amount determined by the sharing amount determination unit 26, the allocation target amount, and the number of persons in each group. A case will be described in which the new share of the A group is determined as the initial share Ma plus the adjustment amount n × Sa. In such a case, since the new share of Group A is known, the value obtained by subtracting the new share of Group A x the number of people in Group A from the amount to be shared is divided by the number of members in Group B. May be used as the new share of group B.

For example, the new share of group A is 4,40
Assuming 0 yen, Group B's new share is (42,34
8−4,400 × 5 (number of group A) / 5/5 (number of group B) = 4069.6 → 4100 yen.

The group allotment calculation unit 28 further calculates the initial burden amount and sends it to the allotment amount determination unit 26.

In the case where the share of the group A is expressed by the share of the group B, the share of the group B can be obtained because the share target amount can be expressed only by the share of the group B. For example, if the allotment of the A group = the allotment of the B group x 1.2, the allocation target amount 42,348 yen = the allotment of the A group x 5 (the number of the A group) + the allotment of the B group x 5 (the number of the B group) ) = 11 × B group's share. Therefore, the share of group B is obtained, and the share of group A is also obtained.

Further, when the share of the group A is increased, the share of the group B eventually becomes zero. Here, since it is meaningless to further increase the share of the group A, the group share calculation unit 28
Means that the share of one or more groups is zero,
If it decreases further, the share is not updated. In other words, the share amount calculated immediately before is held.

The remainder calculating unit 30 calculates the sum of the share target amount and the total share amount of each group based on the share amount of the members of each group, the number of members of each group, and the share amount. Calculate the difference.

When the share amount is calculated, rounding up or the like is performed, so that a difference occurs between the share amount and the sum of the share amounts of the respective groups, and the share amount is assigned to the respective groups. The sum of the sums may increase. The amount that exceeds this,
"Remainder". The remainder calculation unit 30 calculates “remainder”. For example, if the allocation target amount is 42,348 yen, the new allocation amount of the A group is 4,400 yen, and the new allocation amount of the B group is 4,100 yen, the remainder is 4,400 × 5 + 4,100 × 5−42,348 = 152 yen. .

Next, the operation of the embodiment of the present invention will be described.
FIG. 8 is a flowchart showing the operation of the embodiment of the present invention. FIG. 9 is a diagram showing a display screen. Mainly, FIG.
The operation of the embodiment of the present invention will be described with reference to FIG.

First, the user uses the numeric keypad 4c to input the total amount, the donation, and the number of groups (S10: see FIG. 5). As a result, the group allotment amount calculation unit 28
Since the initial burden amounts Ma and Mb can be obtained, the initial burden amounts Ma and Mb are displayed (S12). The display of the initial burden amounts Ma and Mb is, for example, like a screen 100. The initial burden amounts Ma and Mb are displayed in the lower half of the screen 100. Next, the remainder calculating unit 30 calculates and displays the remainder (S
14). The surplus display is, for example, like the screen 100. The remainder is displayed on the bottom line of the screen 100.

In this state, parameters are input from the parameter input section 18 based on the rotation of the jog dial 3 (S16). Based on the parameters, the sharing amount determination unit 26
Decides the share of group A. On the basis of the allocated fixed amount, the group allotment amount calculation unit 28 calculates the allotment amount of each group (S18). At this time, the group sharing amount calculation unit 28 determines whether or not the sharing amount of the A or B group becomes 0 and further decreases (S20). If the share of the group A or B further decreases from 0 (S20, Yes), the process returns to the parameter input (S16) without updating the share.

For example, in the screen 120 of FIG.
The amount of contribution is 0 yen in the composition of the group. In such a state, it is meaningless to further increase the share of the members of the group A. It's just over-collection of the secretary. Therefore, even if an operation (for example, rotating the jog dial 3 to (1)) on the screen 120 is performed to increase the share of the members of the group A, the share is not updated.

If the share of the group A or B does not further decrease from 0 (S20, No), the group share calculation unit 28 displays the share of each group on the display 2 (S22). Then, the remainder calculation unit 30 calculates and displays the remainder (S24). Then, if the sharing amount is determined (S26, Yes), the process is terminated, and if not, the process returns to the input of parameters (S16).

For example, in the screens 110 and 130 of FIG. 9, the sharing amounts and remainders of the groups A and B calculated by the group sharing amount calculating unit 28 are displayed in the lower half of the screen. The screen 110 is a screen in which the operation of rotating the jog dial 3 upward (1) from the screen 100 is performed once. Screen 130 is from screen 120
This is a screen when the operation of rotating the jog dial 3 downward (2) is performed twice. The screen 110 returns to the screen 100 if the operation of rotating the jog dial 3 downward (2) is performed once. The screen 130 returns to the screen 120 if the operation of (1) rotating twice is performed.

According to the embodiment of the present invention, the jog dial 3 is rotated (1) upward, (2) rotated downward,
Based on these parameters, the share determination unit 26 determines the share of the members of the A group, and the group share calculation unit 28 determines the members of the A and B groups based on these. Is calculated. Therefore, jog dial 3
As long as is rotated up and down, it is possible to perform split billing in which the share amount is different for each group, and the split bill can be easily performed.

Moreover, the method of determining the new share of the group A, which has been mainly described, as the sum of the initial share Ma and the adjustment amount n × Sa, is further applied to the embodiment of the present invention. Has an advantageous effect.

In other words, when adjusting the ratio or difference between the share of the group A and the new share of the group B, it is easy to see how the share of the groups A and B changes. I do not know. Therefore, even if there is a request to fine-tune the share of Group A, it cannot be met.

However, according to the method of determining the new share of Group A as the initial share Ma plus the adjustment amount n × Sa, the new share of Group A is determined by the (1) of the jog dial 3. ) Based on the operation of rotating upward and (2) rotating downward, it has been determined that the amount changes by the unit burden amount Sa. Therefore, it is only a new share of the B group that it is not easy to know how it changes. Therefore, if it is desired to finely adjust the share of the group A, but the demand of the share of the group B is not so severe, it is preferable because the share of the group A can be finely adjusted by rotating the jog dial 3 up and down.

In the above embodiment, the case where there are two groups has been described. However, when there are three or more groups, the split billing calculation can be basically performed by the same configuration.

For example, when there are groups A, B, and C, the sharing amount determination unit 26 expresses the sharing amounts of the groups B and C by the sharing amount of the group A, and The share amount may be determined. Alternatively, when the sharing amount determination unit 26 determines the new sharing amount by increasing the initial sharing amount of the group A by Sa, the initial sharing amount of the group B is set to a value uniquely determined by Sa (eg, 0.5 Sa). The allocation may be increased to determine a new allocation, and the allocations of the A and B groups may be determined. Alternatively, adjustment amounts to be added to the initial allocation amounts of the A and B groups may be input.

The above embodiment can be realized as follows. The CPU, hard disk, and media (floppy (registered trademark) disk, CD-ROM, etc.) having a reader for reading a medium having a program for realizing the above parts are read by a media reader of a computer equipped with the reader and installed on the hard disk. I do. Even with such a method, the above function can be realized.

According to the present invention, by inputting the parameters, the sharing amount determining means determines the sharing amounts of the members of each group, and the group sharing amount calculating means determines each group based on these. -Calculate the share of the members of the group. Therefore, by inputting the parameters, it is easy to make a split bill with the share allotted differently for each group.
