DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a card processing device used in an ATM (automated money processing machine) installed in a bank or the like, and a card used in the device.

(Prior Art) Recently, many ATMs connected to postcomputers have been installed in banks and the like, and customers use these ATMs to withdraw money or make payments using cards.

(Problem to be Solved by the Invention) However, when using a card to withdraw or transfer money at an ATM as described above, a slip is issued with the details of the transaction and the remaining amount printed on it. However, it is necessary to install a slip issuing machine with a printing mechanism, which makes the device expensive, and there are also problems in that it takes time and effort to replace the printing paper for the slip.

The present invention was made in view of the above problems, and an object of the present invention is to enable transaction information to be written and displayed on the card itself used in an ATM device or the like.

(Means for Solving the Problems) In order to achieve such an object, the present invention provides the following:
In the invention of 1), the card is composed of a magnetic recording part in which authentication information is written, and a thermoreversible material made by dissolving a resin and an organic low-molecular substance in a solvent, and transaction information is displayed in a rewritable manner. The structure includes a display layer.

Furthermore, in the invention of claim (2), claim (1)
The card is configured to include a means for reading authentication information in the magnetic recording section and a means for heating and rewriting the display pattern in the display layer.

(Function) According to the invention of claim (1), transaction information is rewritably displayed on the display layer of the card, and according to the invention of claim (2), the display pattern of the card of claim (1) is It is rewritten by a rewriting means.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings. Each figure in FIG. 1 is a perspective view showing a pull card in a different display state, and FIG. 2 is a sectional view.

In these figures, reference numeral 1 is a card; card 1
On the front side, a magnetic stripe 6 on which an authentication number, etc. is recorded is provided along the longitudinal direction on one side of the substrate 2'', and a rewritable strip made of a thermoreversible material is provided on the wide side of the stripe 6. A display layer 3 is provided. A transparent overcoat layer 5 for protecting the card is provided on the display layer 3.

The display layer 3 has a structure in which a resin and an organic low-molecular substance are dissolved in a solvent, and as shown in FIG. 3, a large number of organic low-molecular substances 3b are present in the resin part 3a. . The thermoreversible material becomes transparent as a whole when the particles of the organic low-molecular substance 3b become a relatively large single crystal, and becomes cloudy as a whole when it becomes a polycrystal, as shown in Figure 4 below. The material has such thermoreversible properties as disclosed in, for example, Japanese Patent Laid-Open No. 61-2'58853.

In Figure 4, the material shown here is cloudy at room temperature, and when heated, its transparency begins to increase from TI (low temperature).
The transparent state becomes maximum at T2 (medium temperature), and the transparent state is maintained at the maximum transparent state at T2 even after cooling to room temperature. Next, when this is raised to T3 (high temperature), it becomes a state intermediate between a transparent state and a maximum cloudy state, and then when it is cooled to room temperature, it has a property of returning to a cloudy state.

As shown in FIG. 1(A), the card I configured as described above displays the transaction date, withdrawal amount, and remaining amount on the display layer 3 by exposing the substrate 2 in the transparent portion. On the other hand, FIG. 1(B) shows a state in which the entire display layer 3 is cloudy and the displayed content has been erased.

It is taken inside while being sandwiched between.

In this case, the cart 1 is one in which the display layer 3 is displayed as shown in FIG. 1 (Δ), or one in which the display layer 3 is entirely white as shown in FIG. 1 (B). It may be appropriate.

Next, the card I taken into the interior is detected by the photoelectric sensor 27.
Upon detection of (step S3), the authentication information on the magnetic stripe 6 is read by the magnetic head 23 which has started operating (step S4), and the card l is further sent inward and detected by the photoelectric sensor 29 (step S5). The timer is activated (step S6), and the motor 13 is stopped after a predetermined time (step S7). By stopping the motor I3 after a predetermined time as described above, the card 1 is sent into the imprint processing device 40, where the imprint processing of the card 1 is performed.The information read in step 4 is transferred to the ATM. At the same time, the timer is activated (step S9).

By subjecting the entire display layer 3 to the high-temperature T3 treatment in the heater 24 (step 512), the entire display layer 3 is cooled down to the first temperature.
It becomes cloudy as shown in Figure (B). Next, write information is received (step S I 3), and if there is a command to write to the card l (step 514), the medium temperature T is processed by the thermal head 25 (step 515). In the above, 71j=Tp processing is performed only at positions corresponding to the form of the desired display pattern in the display layer 3. The above writing information is given from the control unit of the ATM, and the writing command is given based on the customer's operation command.

Next, as the card 1 passes the photoelectric sensor 26 (step 5I6) (step 517), the cart 1 is conveyed to the insertion/ejection opening II, and the motor I3 is stopped (step 518). If time is over (step 5I9)
Motor I3 also stops.

In this way, if the transaction information for 1iIj times is displayed in step SI2 above, that display pattern is erased, and the display pattern of the current transaction information is written in step 15, so that the display in the display layer 3 The pattern is rewritten.

In the card processing device, only the operation of erasing the display pattern on the display layer 3 can be performed, and the operation is shown in the flowchart of FIG. In this case, in the operation shown in the flowchart in FIG. 7, the reading operation of magnetic information in the magnetic head 23, the writing operation in the thermal head 25, etc. are omitted.

(Effects of the Invention) Therefore, according to the present invention, transaction information is rewritably displayed on the display layer of the card, and the display pattern is rewritten by the heating rewriting means.
It has become possible to write and display transaction information on the card itself, and as a result, it has become possible to avoid issuing slips as in the past.
