Description

[Detailed Description of the Invention] The present invention relates to a practical card-type public telephone card that can display a wide range of degrees in a limited space.

In general, cards used in ticket-type magnetic card public telephones and bus ticket devices have information printed on the magnetic recording section so that the value such as the number of times used so far or the residual value can be visually checked. There is also a frequency display column that is displayed by punching or punching.

Conventionally, this type of display field was used, for example, for card 1 in Figure 1.
0, the cumulative used power and remaining power stored in the magnetic recording unit 11 are displayed at equal intervals in the display field 12, such as 0, 1, 2, 3, etc., and each time the device is used, the corresponding value is punched. I had returned it. Therefore, even though the magnetic recording section 11 can record an extremely large frequency, it is extremely difficult to display a large frequency in the display field 12 due to space limitations. For this reason, it was necessary to either not issue cards with large degrees, or else to make the display intervals coarser, such as every 10 degrees. If the display interval is made coarser, when the remaining power reaches a small value below the interval, the exact power is completely unknown, so the user will not be worried about the remaining power reaching zero during a call and the call being interrupted. This will make you feel anxious.

The present invention was developed in view of the above-mentioned conventional problems, and its purpose is to be able to display a large number of degrees in a limited space, and to prevent the user from feeling uneasy due to the coarse display intervals. To provide an extremely practical card-type public phone card that is not available in the market. The details of the present invention will be explained below with reference to the drawings.

FIG. 2 is a plan view of an embodiment of the present invention;
0 is a card type public telephone card, 21 is a magnetic recording section, and 22 is a frequency display field. This card 20
is a card for 1000 degrees, and the remaining degrees from 500 to 0 are printed in advance in the degree display column 22.

That is, as shown in the example of the remaining power display in FIG. A numerical value sequence is printed in advance such that the difference between adjacent numerical values becomes larger and the numerical value becomes smaller, that is, the difference between adjacent numerical values becomes smaller as the residual value corresponding to the frequency information becomes smaller. If the remaining power in the magnetic recording section decreases with use several times and the remaining power falls below the pre-displayed value, the built-in card will be displayed when the card is returned at the end of the call. A punch mechanism is used to punch the corresponding numerical value. As shown in the figure, in the power display field 22 of the present invention, a large residual power value corresponding to power information is displayed with a large difference between adjacent values, but as the power is used, the remaining power value corresponding to power information is As the value decreases, the punch holes move toward the side where the difference between adjacent numbers is smaller, and the smallest number in the punched hole represents the card's remaining power, allowing users to see it more accurately at a glance. can show the remaining number of degrees. For example, if there is a punch hole only at position 500, the remaining power of the card is 200 to 499 degrees, and if the minimum numerical value position of the punch hole is 5, the remaining power of the card is 2 to 5 degrees. For cards with a large number of issued credits, you only need to increase the difference between adjacent numbers with the first number as the issued number, making it easy to display a large number of remaining credits in a limited space, and even if the remaining number of credits becomes small, the value can be easily displayed. is clearly displayed, so the user does not have to worry about the call being interrupted. Further, the frequency may be displayed in a manner in which numerical values are squared sequentially, in a manner in which 2 ⁿ (n=0, 1, 2, . . . ) is expressed, or in values approximated thereto.

In addition, although we have explained an example in which the remaining power is displayed in the power display column 22, instead of this, the cumulative usage power, for example, the numerical value displayed in the power display field 22 in FIG.
It may also be configured to display a numerical value subtracted from 1000.

In this case, when the numerical value is small, that is, when the residual value corresponding to frequency information is large, the difference between adjacent numerical values is increased and displayed. It is obvious from the purpose of use that the frequency should be displayed in the frequency display column so that the difference between the two is small.

In addition, an example was explained in which the power is printed in advance in the power display field 22 and the corresponding number is punched, but instead of this, the remaining power recorded in the magnetic recording section 21 is 500, 200, 100, etc. It may be configured to print the numerical value when the value falls below a predetermined numerical value such as...

As explained in detail above, the card type public telephone card of the present invention displays a large numerical value when indicating the remaining power, and when the residual value corresponding to the power information is large, the difference between adjacent numerical values is displayed as a large value. As the numerical value becomes smaller and the residual value decreases, the difference between adjacent numerical values becomes smaller.Also, when the numerical value is small when indicating the cumulative usage frequency, and when the residual value corresponding to frequency information is large, the difference between adjacent numerical values is This is a configuration that displays the difference between adjacent values as the value increases and as the residual value decreases, the difference between adjacent values becomes smaller. A numerical string that specifies changing frequency information as an approximate number is displayed by increasing the difference between adjacent numerical values when the residual value corresponding to the frequency information is large, and as the residual value decreases, the difference between adjacent numerical values is displayed. Since the display is configured such that the frequency is small, a large frequency can be displayed within a limited space, and the user does not have to fear that the call will be interrupted. Furthermore, the display format of the card of the present invention can also be used for bus tickets, etc.
