Abstract

PURPOSE:To obtain an electronic calculator which is capable of writing the data supplied from a cash dispenser by utilizing a solar battery serving as a power supply for a data reading means. CONSTITUTION:An electronic calculator main body 1 is put into a cash dispenser and therefore the light emitting body 8 of the cash dispenser is put on a solar battery serving as a photodetecting part. A specific pattern which is usually never generated to the solar battery cell is supplied as a start signal by the body 8. Then the input/output cash amount, the balance, etc. are written to a memory in the calculator by the ON/OFF combinations of the matter 8 and via a parallel input bus 9. The display of the balance, etc. is simplified since all types of information are stored to the calculator.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electronic desktop calculator (hereinafter simply referred to as a calculator) equipped with a solar cell.

Structure of the conventional example and its problems Conventional calculators are known to be the same size as cash cards and credit cards. On the other hand, the recent competition to make calculators thinner has been remarkable, and finally a thin calculator with a size smaller than 1 has been developed.

Purpose of the Invention The present invention was made in view of the development status of such calculators, and provides an electronic desktop calculator that allows the calculator itself to be used as a cash card or credit card, and allows data to be written from a cash dispenser. The purpose is to provide

Structure of the Invention In order to achieve the above-mentioned objects, the present invention is characterized in that a solar cell installed next to a power source is used as a data reading means.

According to this configuration, when the solar cell is irradiated with a special optical pattern of data light in the cash dispenser, the solar cell operates as a data input device;
All data from the cash dispenser can be written to the internal memory of the calculator. Therefore, whereas with conventional cash and IC cards, data can only be read from the magnetic recording area on the cash card within the cash dispenser, data can now be written from the cash dispenser to the calculator itself. It has the advantage that it can greatly improve the convenience of people.

DESCRIPTION OF THE EMBODIMENTS FIGS. 1 and 2 show an embodiment of the electronic desktop calculator of the present invention. In FIGS. 1 and 2, the main body 1 has a thin structure, and a solar cell 2 is placed on one plane of the main body 1.
, a display 3 for displaying calculation results, and a keyboard 4 for inputting numerical values for calculations, division, addition, 9 multiplication, etc. Information from the keyboard 4 is input to an integrated circuit 5 for calculation, and a predetermined calculation result is displayed on the display 3. Here, the calculator main body 1 is provided with a rechargeable battery 6 in addition to the solar battery 2 as a full power source, and is also driven by this battery 6. Although not shown, the main body section 1 has a magnetic recording section on the back surface thereof.

In such a configuration, when the main unit 1 is inserted into the cash dispenser, the cash dispenser reads the passbook number and PIN number from the magnetic recording section on the back side, compares it with the PIN number entered by the customer, and checks if they match. After that, if a passbook is inserted into the cash dispenser at the same time as the card, the withdrawal amount and withdrawal amount will be displayed on the passbook, or on a piece of paper if the passbook is not inserted. The remaining amount, etc. are displayed, but in this embodiment, when the thin calculator is inserted, the remaining amount, etc. is not written on a piece of paper, but is recorded on the inside of the calculator.

That is, in this embodiment, when the main body part 1 is inserted into the cash dispenser, the light emitter 8 of the cash dispenser is arranged so as to overlap the solar cell serving as the light receiving part, as shown in FIG. . Here, the light emitter 8 causes a specific turn, e.g. eli Qiφ1.
A pattern such as Φ1 that does not normally occur in solar cells is given as a start signal, and then the light emitter 80 is turned on.
Depending on the combination of turning off the lights, the parallel input bus 9 can be used to write in the memory of the calculator the amount of withdrawals, balance amount, etc. as recorded on the passbook. Therefore, according to this embodiment, the amount of withdrawals, etc. There is no longer a need for the paper that was used to fill in and print out the information, and all the information is stored on the flat-screen calculator. By just doing this, you can immediately display the excess or deficiency of your bank balance, and since information is transmitted between the thin calculator and the scanner by light, there are no mechanical contacts and no noise. It can be made strong.

Effects of the Invention The present invention uses solar cells as the parallel input means for the data input means, so it can not only be constructed at a very low cost, but also the output device of the cash dispenser can be constructed using only a light emitting body such as a light emitting diode. The benefits are impressive, such as not requiring a special input/output device and storing all the data in the despenser on top of it, making it much more convenient for card users.
