Abstract

PURPOSE:To reduce the load on information stored on a card and to facilitate the manufacture of software by enabling the touch input of dedicated key information on each IC card from on a panel through which the dedicated key printed surface of the card is seen. CONSTITUTION:The touch input type console panel 2c having a thin-film transparent electrode of matrix structure with high transmissivity through which the printed surface of the card is seen is provided above a pocket 2a into which the card 1 is inserted, and the touch input of dedicated key information on the IC card 1 from on the panel is enabled. Data stored in the ROM of the IC card 1 include matrix electrode position information of the console panel 2c corresponding to key information positions on the printed surface and a main device 2 reads the data and judges the contents of a touch input, i.e. input address at a specific position on the panel 2c. For example, electrode positions B2, B3, and B4 on the console panel 2c correspond to 'amount with interest included' at the printed part on the IC card 1 and an electrode position C8 corresponds to '6', so that the touch input at a specific position on the panel is judged.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a desktop calculator that allows a wide variety of calculations and information to be easily obtained.

[Prior Art] Conventional desktop calculators can only obtain calculation results by operating unique keys such as the four arithmetic operation keys, numeric keys, and function keys, and cannot perform other calculations. Instead, it was necessary to prepare a separate desktop calculator with dedicated calculation keys required depending on the purpose of calculation.

To solve this problem, the computer is equipped with multiple storage media that store dedicated calculation programs, and by exchanging each storage medium, the computer itself reads the information on each storage medium and stores various information according to the calculation program. There are things to look for.

[Problems to be Solved by the Invention] However, in the above-described system, the computer main body must be equipped with a plurality of dedicated keys for executing the arithmetic program on each storage medium, and any one of the plurality of dedicated keys must be provided. When selecting and performing an operation, key operations were complicated.

Therefore, the present invention was made to solve the above-mentioned problems in the conventional example, and it is possible to perform a wide variety of calculations with simple operations without the need for special keys for executing each program. The purpose is to obtain a desktop calculator that can.

[Means for Solving the Problems] The desk calculator according to the present invention stores dedicated calculation programs and data, and has dedicated key names for executing calculations printed at predetermined positions on the surface. Naru I
The computer main body, which is equipped with multiple C cards and reads calculation programs and data from each card, has the above
An operation panel with a thin film transparent electrode of high transmittance in a matrix structure is provided on the card loading pocket into which the C card is inserted, and the dedicated key of each IC card can be accessed from the panel through which the printed surface of the dedicated key on the card can be seen. This allows touch input of information.

Effect 1 The desktop calculator of the present invention basically has a ROM for storing dedicated programs and data for the IC card.
There is no need to install general-purpose software on the main body, operation is simplified, and a wide variety of information can be obtained flexibly.

[Example] Hereinafter, an example of the present invention will be described based on the drawings. Figures 1 (a) to (d) are external views showing the IC card and the computer main body. Figure 2 is a system configuration diagram.
), a dedicated program and data for calculating interest rates are stored in the ROM, and on its surface,
As shown in (a), dedicated key information is printed at predetermined positions.

On the other hand, the above-mentioned IC card (1) is installed on the computer main body (2) side.
A card mounting pocket (2a) is provided for mounting the IC card (1), and when the IC card (1) is mounted in this pocket (2a), the output terminal (l) provided on the back side of the card is inserted.
The programs and data in the card are transferred to the main unit, that is, the CPU (2
e) and temporarily stored in the memory (2f).

However, the card (1) is inserted into the pocket (2).
a) A conventionally well-known touch input type operation panel (2C) having a thin film transparent electrode with a matrix structure with high transmittance through which the printed surface of the card can be seen is provided at the upper position;
Touch input of dedicated key information for the IC card (1) is possible from this panel. In other words, an IC card (
The data stored in the ROM of 1) includes matrix electrode position information of the operation panel (2c) corresponding to the key information position on the printed surface, and the main body (2) side reads this data and displays the panel. (2c) It is possible to judge the contents of a touch input at a predetermined position above, that is, an input address. For example, the electrode position B2, B3, or B4 on the operation panel (2c) corresponds to the printed part "Principal and Interest Total" on the IC card (1), and the electrode position CB corresponds to "6" on the panel. A touch input at a predetermined position is determined. Note that (2d) indicates a display panel.

Figure 3 shows a flowchart based on an example of interest calculation.
By implementing in a), the contents stored in the card, that is, the interest rate calculation program and data are read into the memory (2f) (step Sl), and the CPU (2e) runs the interest rate calculation program (step S2). )
, L, and electrode position C on the operation panel (2C)
When given a touch input on 2 or C3 or C4, “loan repayment” can be entered and the display panel (
2d) Above is “Ganrikisoto OR Gankinkinto?
” are displayed (step S3).

Next, electrode position E1 or B2 on the operation panel (2C)
When you select and input "Principal and Interest Equalization" by touching , characters are displayed on the display panel (2d) as shown in the figure, and interest calculation is performed by inputting in a conversational format (Step S4). S5), as shown in the figure, the calculation result will be displayed as "Hentai Gaku=○OOOen/Tsuki" (Step S8), and you will be asked to select whether or not to end the process (Step S7). If it is the end, remove the card. As a result, the contents of the memory (2f) in the main body are cleared (step S8) and the process ends. If the process is continued, S2 to S7 are repeated again.

In addition, although the above embodiment describes an example of interest rate calculation, other types of numerical tables, scientific and technical calculations, tax calculations, various fares, charge calculations, critical times, train timetables, food calorie calculations, etc.
Application list, various games, Tsume Go, Tsume Shogi, various history calculations, biorhythm, various insertions, national radio frequency, T
A wide variety of information such as V channel numbers, cost calculations, and estimate calculations can be obtained by simply replacing the IC cards that store dedicated programs and data.

Furthermore, it goes without saying that the desktop calculator can be used not only for calculations but also for searches.

[Effect of the invention] As described above, according to this invention, the IC card has RO
It is only necessary to provide the M function, the burden of information to be held on the card can be reduced, and software production can be facilitated. Further, unlike the conventional example, there is no need to provide general-purpose software common to various calculations on the main body side, and the operation can be simplified, and a wide variety of information can be obtained.
