Description

[Detailed description of the invention] (b) Industrial usage total The present invention relates to an information processing card.

(b) Prior art At present, electronic calculators are designed to have thinner key input sections, arithmetic sections, and display sections, and to use solar cells as the driving power source. Card-type devices with a thickness of less than 2wn, such as the CX12, have been realized.

Furthermore, in what is now called the card age, individuals have come to own a plurality of identification cards such as credit cards, cash cards, and cards for the purpose of room access management.

Conventionally, this type of identification card includes one with a magnetic tape pasted on it and identification data recorded on the magnetic tape.
There are cards on which a hologram corresponding to identification data is formed. Furthermore, recently, as disclosed in Japanese Patent Publication No. 53-6491, an integrated circuit that generates a new signal for identification in response to external input is embedded as an identification device in order to counterfeit cards. This type of card has become widely popular in recent years.

(c) Problems that the invention aims to solve In this increasingly hot card era, as the number of cards owned increases, including card-type electronic calculators, storage becomes a problem.

(d) Means for solving the problems The present invention aims to solve the problems as much as possible.
Its structural features include a calculation means that performs calculation processing in the main calculation section based on numerical information and calculation information input from the key input section, and a new signal generated in response to input from the external threading means. The present invention further includes an identification means outputted from the external threading means.

(E) Function: An electronic calculator with this type of configuration normally works as an original electronic calculator, and when a signal is input from the external connection terminal, a new signal corresponding to the input is generated and output. serves as an identification card.

(v) Embodiment FIG. 1 shows an embodiment of the present invention, and (1) has a thickness of 2ra.
The main body of a card-type electronic calculator, (2) to (4) are ``solar cells, a display section,
It is a key input section, and the thick vIk1E cell (2) is made of, for example, amorphous silicon, and the display section (3) is made of, for example, amorphous silicon.
consists of, for example, a liquid crystal display. In addition, the key input section (4)
) has a plurality of numerical keys, a plurality of function keys for instructing addition, subtraction, multiplication, and division, and a switching key (5) for switching between a calculation mode that functions as a normal electronic calculator and an identification mode that functions as an identification card. have. <6)(6)・
. . . is an external connection terminal as a means for inputting and outputting signals with external equipment, and serves as a row terminal for inputting signals from the outside and outputting signals to the outside.

FIG. 2 shows the circuit configuration of this embodiment, where (7) is a main processing section consisting of, for example, a microcomputer, and the main processing section is operated by a key input section (4) or Processes signals input from the external connection terminal (6). (8) is a power supply stabilization circuit,
The circuit stabilizes the power generated from the solar cell (2) and supplies the stabilized power to the main processing section (7) and the display section (3) as driving power.

FIG. 3 is a flowchart showing the operation of the main calculation section (7), and the operation of this embodiment will be explained below based on this flowchart.

First, in step 31, initialization is performed.

Such initialization resets the display state of the display section (3) and sets the variables mode and C00T on the control program to a.
The above variable taade indicates the processing mode of the device; when mode is O, the device is in the calculation mode, and when modem is 1, the device is in the identification mode.The variable C0UT is the identification mode, which will be described later. This is for calculating the number of food inputs.

Next, in step S2, it is determined whether or not the switching key (5) has been input. If the switching key (5) has been input, the process proceeds to step S3; otherwise, the process proceeds to step S6.

In step S3, it is determined whether the modem is O,
When mode-0, 5Ode is set in S4 step.
is changed to ml”, and when mode-ml is set to S
In step 5, +mode is changed to "0".

54. Upon completion of step S5, the process proceeds to step S6.

In step S6, it is again determined whether modem O is selected, and if mode-0, the process proceeds to step S7; otherwise, the process proceeds to step S9.

In step S7, numerical calculations are performed based on the numerical key manual signals and function key manual signals inputted from the key input section (4), as is done in a normal electronic calculator, and the results and calculation process are displayed on the display section ( 3). S
When the 7 steps are completed, the process returns to step S2.

In step S8, it is determined whether the content of C0UT is "3" or more, and when COυT≧3, the process returns to step S1, and when C0UT<3, the process advances to step S9. The following steps constitute identification mode processing.

In step S9, the system waits for the input of the identification hood ID 2 from the key input section (4), and the identification hood ID 2 determines, for example, whether the user of the device is the true user or owner. A true user or owner remembers the identification hood IDi defined in advance in the control program, and can therefore input the same identification hood ID2.

Identification code ID2 input in step S9 above
It is determined in step S10 whether or not it is the same as the identification code IDI, and if IDI≠ID2, the process goes to step 31.
The process advances to step S8, in which the content of 000 copies is counted up by "1", and then the process returns to step S8.

Therefore, if the identification hood ID2 that can be input in step S10 differs from the identification hood IDI three times in a row, the 58
The loop consisting of steps .about.Sll is processed three times, and the process returns from step S8 to step 81.

Further, if it is determined in step S10 that ID1-ID2, the process proceeds to step S12.

In step S12, the content of C0UT is set to 0'', and then in steps S13 to S15, the same identification operation as in the past is performed. That is, in step S13, an external signal input from the external connection terminal (6) is waited, and in step S14, In step 815, the above-mentioned input signal is processed based on processing predefined by the control program, and in step 815, the processed signal is outputted via the external connection terminal (6).

Upon completion of step S15, the process returns to step S2.

In this way, the device of this embodiment can easily be used both as a normal electronic calculator and as an identification card by simply inputting the switching key (5).

In addition, in the identification mode of the device of this embodiment, as a step before using it as a normal identification card, it is necessary to check whether the user of the identification card is the true user or owner as shown in steps 58 to 811 above. Since we are determining whether
For example, even if the real user or owner leaves such a device on a desk and a third party obtains the device, such third party can be prevented from using it as an identification card.

In this embodiment, a solar cell was used as a power source for driving the display section (3) and the main processing section (7), but a thin battery having a thickness of about 0.5111 mm may also be used.

In addition, in this embodiment, the main calculation unit (
7) was also used for processing externally input signals, but
A separate arithmetic unit may be provided for processing signals input from the outside.

Further, as a means for connecting with external equipment, an external connection terminal is provided for electrical connection, but it is also configured for optical connection using a well-known light emitting element and/or light receiving element. Also good.

(g) Effects of the Invention By using the configuration of the present invention in a card-type electronic calculator, a conventional card-type electronic calculator and an identification card can be integrated, and the number of cards held by an individual can be reduced.
