Abstract

PURPOSE:To calculate rationally and instantly the purchase amount of money of n-way of a pari-mutuel ticket and its effect by inputting odds of pari-mutuel tickets of n-way to be purchased to a prescribed profit amount and conducting a prescribed arithmetic operation. CONSTITUTION:The calculator is provided with numeric buttons (0-9) 7, a decimal point button 8, a memory button 9, a clear button 10, an output button 11, a partial input or clear button 12 and a switch 13. Further, a frame order or horse order display 1, an odds display, a profit amount display 3, an investment efficiency display 4, a purchased monetary amount display 5 and a purchased monetary amount total display 6 are provided. In inputting the odds of the n-way of mutuel tickets to be purchased to a purchased to a prescribed profit, the purchased monetary amount is outputted.

Description

[Detailed Description of the Invention] This invention uses the basic formula (1) to calculate the purchase amount in order to obtain a certain amount of profit set for any given betting ticket when purchasing n-time betting tickets. This relates to the admission output and arithmetic device based on it.

Previously, I had filed a patent application dated May 28, 1980 for a small electronic calculator based on the same technical idea, but this time I will create a natural law called basic formula (1) when G is constant, and apply it accordingly. This is the development of a computing device based on the above, and it is possible to create a simple and practical dangerous type.

The present invention is a pioneer in this field and will be described below.
Sections 5 to 5 explain basic table examples and commercialization of arithmetic devices.

In the case of 1 n; 1, the basic formula (1) and formula (2) are obtained.

Now, G=5,000. If α=5, then X=1,250
get.

2 In the case of n-2, formula (3) is obtained from basic formula (1).

Basic formula (1) also holds true when 3n=3 or more.

However, since the profit amount G is positive, the denominator of K in basic formula (1) must be positive, and conditional formula (4) must be satisfied.

4 This is a small electronic calculator with a built-in solution method based on the basic formula (1) and an output device for nine people, but n=
If the 0 conditional expression (4), which allows production of about 10 products to be made into a single product, does not hold, press the partial clear button to n'Ih.
All you have to do is delete them one by one until the horse racing ticket F) is established.

5 Investment efficiency β is expressed by equation (5)K.

The present invention has the above-described structure, and when used, inputs the odds of n different horse racing tickets to be purchased for a certain profit amount, and outputs the purchase amount.

Therefore, the present invention can rationally and immediately calculate the purchase amounts of n different horse racing tickets and their effects in accordance with the odds.

Claims (1)

[Scope of Claims] l When purchasing n types of horse racing tickets, the following basic formula (1) is established between the odds and the purchase amount, in addition to obtaining a certain amount of profit no matter how you choose. To establish. Here, Xi = First deposit amount of the purchaser's horse racing ticket G = Profit amount from any sick horse racing ticket α1 = Purchaser's horse racing ticket l first prize 2 Input G and α1, and enter the basic formula in claim 1 Arithmetic device 03 that outputs the solution Xi based on (1) A small electronic calculator configured as described above, which can also be applied to purchasing tickets for boat races and bicycle races.
