[Detailed description of the invention] The present invention relates to electronic computing devices.

In addition, in this specification, the electronic computing device refers to the four arithmetic operations,
Small portable devices that process information electronically, such as electronic translation, electronic storage, and alarm devices with built-in sensors for temperature, humidity, radiation, etc., and also include IC cards that store information inside the device.

Hereinafter, a business card-sized card-type electronic calculator (hereinafter referred to as a card calculator or card) is an example of an electronic computing device.
I will explain about it.

Conventional card calculators are thin and very convenient, but they only have a single function as a calculator. Therefore, it had the disadvantage of being of limited use.

The present invention eliminates these drawbacks and provides a versatile electronic computing device.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

) and serves as the power source for the card calculator. Of course, a small rechargeable battery (not shown) is provided inside the main body.

The MT3b is attached to the center of the lower case 2, and the MT3a and 3c are attached parallel to each other in line-symmetrical positions with respect to the same MT3b.The same information is recorded on the MT3a and MT3c in opposite directions, and the left and right sides are reversed. Even if a card is inserted into a disc, it can be played using the same magnetic head.

7 is a card calculator (hereinafter also referred to as a card) configured as described above.

The card 7 in this embodiment can perform four arithmetic calculations as a calculator. Furthermore, since the MTP 3 is provided on the back surface, malfunctions due to external magnetic noise can be reduced. M
If a permanent magnet (not shown) is used instead of TP3, the iron plate (
Since the card 7 sticks to the card (not shown), there is no need to hold it in the hand, which is convenient.

Also, if you keep it in your chest pocket, the magnetic effect will improve blood circulation and help improve your health.

Next, an application example in which this embodiment is used as a cash card calculator will be explained using FIG. 4.

Reference numeral 7 in the figure is the card of this embodiment shown in FIGS. 1 to 3, and the MTP 3 has a cash card PIN number recorded therein.

10 is an automatic cash dispensing machine (hereinafter referred to as CPM) from which cash can be withdrawn using the card 7; 11 is a character display section; 12 is an operation section for inputting a password; 1
3 is a pair of rollers. The pair of rollers B is for guiding the card 7 to the position regulating portion 14 when the card 7 is inserted in the direction of the arrow from the card insertion slot. Reference numeral 15 indicates a magnetic head that contacts the MTP 3 on which a password has been magnetically recorded in advance and reads it by moving the card 7 in the direction of the arrow. Reference numeral 16 indicates a reader for converting the output reproduced by the magnetic head 15 into a pulse code signal. It is a machine. 17 determines whether the password manually entered from the operation section 12 and the password recorded on the tape section (MTP) 3 match or do not match, and if they do not match, displays a re-operation on the character display section 11; In this case, the automatic cash dispensing machine 10 is connected to the central computer section (not shown), and if the amount requested for payment from the operation section 12 is less than the balance stored in the central computer section, a message indicating payment permission is displayed on the character display section. 11, and further operates a cash payment section (not shown) to pay cash and output the balance after payment to the balance output section 18. Reference numeral 19 denotes a group of pins that are selectively moved up and down by the balance output unit 18. Further, each pin 19 is located corresponding to a push button of each KEY 4 of the card 7. and,
The balance output unit 18 inputs the number equivalent to the balance after payment to the card 7 by selectively moving the pin group 19 up and down.

By doing this, the current balance is displayed on the LCD 5 of the card 7.

At this point, the roller 13 rotates in the opposite direction to that at the time of insertion and pushes the card 7 out of the insertion slot.

A lamp 20 illuminates the SBATT 6 of the card 7, and is lit only while the card 7 is inserted.

Furthermore, since the rollers 13 sandwich only the both ends of the card 7 from above and below, even if the card 7 passes between the rollers 13, the LCD
The balance displayed in 6 will not disappear. K
EY4 may be set one step lower than the surrounding area.

By doing this, only the person in question can be informed of his or her balance, and the user only has to perform a clearing operation immediately after the item has been used, and if it is necessary to memorize it, the memory can be operated.

In this embodiment, there are three magnetic tapes 3 on the surface of the lower case 2.
Although an example is shown in which MTPs a, 3b, and 3c are attached, one or more MTPs or a magnetic layer may be provided on the entire surface of the lower case 2. Furthermore, the MTP 3 may be provided on the upper case 1 as well.

In addition, although we have shown an example of a cash card, it can also be used for health insurance cards, health management cards, membership cards, commuter passes, electronic checks, identification cards, driver's licenses, etc. Its range of applications is also extremely wide.

In addition, although an example was shown in which the pin group 19 was selectively moved up and down mechanically as a method for inputting the balance display into the card calculator 7, the present invention is not limited to this. A modulation section and an infrared light emitting section are provided on the automatic cash dispenser side, and the balance output is modulated via the modulation section,
The infrared light may be sent from the infrared light emitting section to the light receiving section of the card, demodulated, and then displayed on the LCD 5.

Further, the present invention is not limited to card calculators as in the above embodiment, but can also be applied to IC cards as described in the Yomiuri Shimbun (evening edition) dated July 9, 1981. That is, I
The upper case or lower case of the C card (it may not be divided into upper and lower cases; in this case, the upper case refers to the surface of one case, and the lower case refers to the surface of the other case) has a magnetic field. Even if a tape, a magnetic layer, a permanent magnet, etc. are provided, the same effect as described above can be achieved (therefore, such an IC card is an embodiment of the present invention), and by doing so, the IC card
1 for automatic cash dispensers for type cash cards and also for automatic cash dispensers for old magnetic tape type cash cards.
It is convenient because it can be handled with just one card. In addition, the shape is not limited to a card shape or a sheet shape, as long as it is small, it may have a housing as a case, and the thickness may be about 2 mm to 30 mm or more. .

Furthermore, the MTP may be used as part of the memory for a calculator, for example, as a reference signal source for correcting the reference value of a digital tester.A barcode may be printed in place of the MTP, so that the barcode reader can check its accuracy. It may be used for checking whether the MTP is correct, or the MTP may be used as an external storage element (device).

The permanent magnet may be any metal magnet, rubber magnet, ferrite magnet, plastic magnet, or the like.

Although the example of SBATT6 is shown, the present invention is not limited to this, and even if the power source is a primary battery, the above-mentioned permanent magnet may be made movable or on a ball, and moved near the coil to generate an electromotive force in the coil. This may be used by charging it into a rechargeable battery.

As described above, according to the present invention, one or one small electronic computing device can be used for more purposes.
