Abstract

PURPOSE:To easily perform the reading and registration of data in a card by providing a function switch to perform the reading and registration of the data in the card on the upper plane of the card. CONSTITUTION:The function switch 1g and a code switch 1h composing of sheet keys covered with a sheet so as not to be exposed to the outside are provided on the upper plane of an IC card 1 as the function switches. And the IC card 1 is compounded so as to provide functions as, for example, as ID code in a building, a pre-paid card to be used at a dining hall, etc., and a call registration card to perform the call registration of an elevator. As the data structure of the IC card 1, for example, data of four digits represented in (0007) of the ID code is inputted behind the function of an (ID), that of five digits represented in (10000) yen of the balance of the pre-paid card behind an (M) function, and that of two digits represented in (06) floor of the destination of the elevator behind an (E) function, respectively. Thereby, the reading and registration of the data in the card can be easily performed.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a contactless IC card that transmits and receives data to and from a card reader in a contactless manner wirelessly using radio waves or the like.

(Prior Art) Fig. 2 shows a conceptual diagram explaining data transmission and reception of a non-contact type IC card disclosed in, for example, Japanese Patent Laid-Open No. 198387/1983, and Fig. This shows the circuit block diagram within.

In the illustrated configuration, when the IC card (1) approaches the identification device (2), which is a card reader, the receiver (1a)
The microcomputer (1d) receives the transmission command from the identification device (2) and receives the data demodulated by the modulation/demodulation circuit (IC).
c) and is then modulated and transmitted from the transmitter (1b). At this time, the identification device (2) identifies the data, for example, collates the ID code, confirms the amount in the case of a prepaid card, subtracts the amount used, and rewrites the data in the card. When the code data prepared in advance is received, an announcement such as "Welcome Mr. XXX" or a command for a specific service is given to a predetermined location. Note that (le) indicates a memory section, and (1f) indicates a battery.

(Problem to be Solved by the Invention) However, the above-mentioned conventional contactless IC card does not have a display section, and therefore, when used as a prepaid card, there is a problem in that the remaining amount is known only when the card is actually used. was there.

Furthermore, a dedicated writer is required to register data in the card's internal memory section (le), and there is a problem in that simple data registration is not possible.

This invention was made in order to solve the above-mentioned problems.It is easy and inexpensive to know the remaining amount on the card in the prepaid system, the remaining number of tickets in the case of a coupon ticket, etc., and also to register the destination of the elevator. The purpose is to obtain a contactless IC card that can also register data for.

(Means for Solving the Problems) A contactless IC card according to the present invention is a contactless IC card that transmits and receives data wirelessly to and from an identification device using radio waves, etc. One or more function switches for registration are provided on the top surface of the card.

(Operation) In the present invention, the function of the function switch is set in advance depending on the use of the IC card, and the function switch reads and registers the data in the card according to the use.

〔Example〕

An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows an embodiment of the present invention, and FIG.
is an internal configuration diagram of the IC card (1) corresponding to Fig. 3, (b) is a top view of the IC card (1), and (C) is an I
A data structure diagram in the C card (1) is shown. In this embodiment, as shown in FIGS. 1(a) and 1(b), the function switch (2) is composed of a sheet key (2) covered with a sheet so as not to be exposed to the outside.
Ig) and code switch (lh), IC card (1)
An IC card (1) can be placed on the top surface, for example, an ID card in a building, a prepaid card used in a cafeteria, etc.
It has also been combined to have the function of a call registration card for registering elevator calls. As for the data structure in this IC card (1), for example, as shown in the same figure (C), the ID code is r 00 after the "ID" faction.
The prepaid balance is 4 digits shown as 07J, the prepaid balance is 5 digits shown in J yen after the "M" faction, and the elevator destination is 2 digits shown as the "06" floor after the "E" faction. There are people. Other data such as expiry date is omitted.

The IC card (1) having the above configuration functions as follows. For example, it is inconvenient to know the remaining amount only when you go to the restaurant and pay the bill, so if you want to know the remaining amount in advance, switch the faction switch in front of the identification device (2) that is only used to display the remaining amount. Press (Ig) once. Then, only the next amount data of faction M is transmitted from the card (1), and 10000 is displayed on the identification device (2). Next, when you get on the elevator, since 6F is usually registered, the identification device (2) between elevators is 06
is detected and automatically registers the call on 6F.

If you want to go to the 8th floor, use the faction switch (I
g) twice, then press the code switch (1h) eight times. Then, in the data structure shown in FIG. 1(C), E, which indicates an elevator, becomes EO8. Since EO8 is registered in advance, when you enter the elevator with this card, your call will be automatically registered on the 8th floor.

In the above embodiment, two function switches are shown, but there may be three or more function switches. In addition, in addition to the faction and code switches, an entry switch is provided as a function switch for registration confirmation.
The operation may be performed at the time of registration confirmation. Furthermore, although the function switches have been explained using sheet keys, touch keys may also be used. Furthermore, to prevent erroneous operation, it is preferable that the input signal from the switch to the microcomputer be of an intermittent type with regular intervals.

(Effects of the Invention) As described above, according to the present invention, by providing a contactless IC card with a small number of simple function switches without using a display or numeric keypad, it is possible to read and register data on the card. A card that is easy to make, inexpensive, and easy to use can be obtained.
