Abstract

(57) [Abstract] [Purpose] To provide a very practical magnetic card system that effectively and visually displays, in a limited space of a magnetic card, a large residual frequency to a small residual frequency according to the usage amount. [Structure] A magnetic card in which value information is magnetically recorded and numerical values from the value that indicates the residual value of the card to zero that indicates that there is no residual value are displayed as numerical value columns at appropriate intervals on the card surface. If a magnetic card is used and the residual value is less than or equal to any of the numerical values that make up the numerical value sequence, a punch hole is opened near the numerical value so that the residual value of the magnetic card can be visually checked. return.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a practical magnetic card such as a card for public telephones, which can display a wide range of frequencies in a limited space.

[0002]

[Prior art]

 Generally, cards used in magnetic card-type public telephones such as coupon tickets and bus ticket devices, etc. A frequency display column is provided for printing and punching.

Conventionally, this kind of display field is, for example, like the card 10 of FIG. 1, the cumulative usage frequency and remaining frequency recorded in the magnetic recording section 11 are 0, 1, 2, 3, ... It was displayed in the display columns 12 at equal intervals and punched out the corresponding numerical value each time it was used and returned it.

[0004]

[Problems to be solved by the device]

 Therefore, although it is possible to record an extremely large frequency in the magnetic recording portion 11, it is extremely difficult to display a large frequency in the display column 12 due to the space limitation. For this reason, it is necessary not to issue a card with a large frequency, or to make the display interval coarser, for example, every 10 frequencies, if not. If the display interval is made coarse, the exact residual value is completely unknown for small values below the interval, so the user may be afraid that the residual value may become zero during a call and the call may be interrupted. I will hold you.

The present invention has been made in view of the above-mentioned conventional problems, and an object thereof is to display a large frequency in a limited space and a display interval is rough so that the user can The aim is to provide an extremely practical magnetic card system that does not cause any anxiety.

[0006]

[Means and Actions for Solving the Problems]

 In order to solve the above-mentioned object, the present invention magnetically records value information, and at the same time, a numerical value sequence from a value indicating the residual value of a card to a value indicating zero is indicated as a numerical value on the card surface. Prepare magnetic cards that are displayed at appropriate intervals, and if the residual value becomes less than or equal to any of the values that make up the numerical sequence by using the magnetic card, make a punch hole near that value. Then, the residual value of the magnetic card is visually returned.

【Example】

 FIG. 2 is a plan view of an embodiment showing the present invention by taking a card-type public telephone card as an example. Reference numeral 20 is a card-type public telephone card, 21 is a magnetic recording section, and 22 is a frequency display column. This card 20 is a card for 1000 frequencies, and the remaining frequencies from 500 to 0 are printed in advance in the frequency display column 22. If the remaining number decreases with use several times and falls below the number displayed in advance, when the card is returned due to the end of the call, etc., the corresponding value is set by the punch mechanism built into the public telephone. Punches are made at these locations. In the frequency display column 22 of the present invention, as shown in the figure, large residual frequencies are displayed at coarse intervals, and small residual frequencies are displayed at dense intervals. Therefore, a large remaining frequency can be easily displayed in a limited space, and even when the remaining frequency becomes small, the value is clearly displayed, so that the user does not have to worry about interruption of the call. Further, the frequency can adopt a display format in which numerical values are sequentially squared, an n-th power of 2 (n = 0, 1, 2, ...), or a display format of values approximate to them.

Further, the example of displaying the remaining frequency in the frequency display field 22 has been described, but instead of this, the cumulative usage frequency, for example, a value obtained by subtracting the numerical value displayed in the frequency display field 22 of FIG. 2 from 1000. May be displayed. Also, an example has been described in which the frequency is printed in advance in the frequency display field 22 and the portion of the corresponding numerical value is punched. However, instead of this, the remaining frequency recorded in the magnetic recording unit 21 is 500,200. , 100, etc., may be configured to print the numerical value when it becomes less than a predetermined numerical value.

[0009]

【effect】

 As described in detail above, according to the present invention, the numerical sequence for indicating the residual value on the magnetic card is adjacent to the one whose residual value is closer to zero than the difference between the adjacent numerical values with the larger residual value. It is displayed so that the difference between the numerical values becomes small, and when the residual value after use is less than or equal to one of the displayed numerical values, the residual value in the numerical value string displayed on the magnetic card Since punch holes are gradually opened in the vicinity of numbers close to each other, even if a numerical sequence showing a large residual value is displayed in the limited space of the magnetic card, the punch holes can be immediately viewed along the numerical sequence. However, there is an advantage that the residual value is easy to see.

In addition, when a conventional magnetic card in which the differences between adjacent numerical values are evenly spaced is forced to display a numerical sequence showing a large residual value, punch holes are overlapped each time the magnetic card is used, There is a risk that it may be easily damaged or the user may be injured by his / her finger or the like, but the present invention has the advantage of eliminating such fear at all.

Claims (1)

[Scope of utility model registration request] 1. A residual value is set to zero based on a difference between adjacent numerical values having a larger residual value in a numerical sequence for suggesting the residual value, which has a magnetic recording portion for recording value information indicating the residual value. In order to reduce the difference between the adjacent numbers on the closer side, at least prepare a magnetic card that is displayed in the longitudinal direction on at least one side, and read the value information of the magnetic recording part of the magnetic card each time it is used. In order to reduce the residual value according to the usage amount, the value information is rewritten to a value corresponding to the residual value, and the residual value of the magnetic card after use is less than or equal to one of the numerical values in the displayed numerical value column. Sometimes, a magnetic card method is characterized in that a punch hole is formed in the vicinity of a numerical value close to the residual value in the numerical string displayed on the magnetic card, the residual value is made visible, and then the magnetic card is returned.
