Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a magnetic dial card and a card dial device, and more specifically, to a card with a telephone number attached with a magnetic code and an automatic device that reads the magnetic code of the card. Concerning dialing devices.

[Prior Art] Conventionally, a telephone card type telephone device is known in which a telephone number is magnetically recorded on a telephone card and automatic dialing is performed by inserting the telephone card.

Furthermore, barcode-type telephone devices are known in which a telephone number is printed on a card as a barcode, and the barcode is read optically to automatically dial the card.

[Problems to be Solved by the Invention] The conventional telephone card type telephone device described above has the problem that the telephone card is expensive and cannot be handed out like a business card. Another problem is that it is not possible to easily create telephone cards in ordinary households.

On the other hand, barcode telephone devices are not suitable for long-term use because dirt can cause phone number reading errors, so care must be taken when handling them, and barcode reading errors occur when the card gets old. There is a problem.

Therefore, an object of the present invention is to provide a magnetic dial card that is inexpensive, can be distributed like a business card, can be easily made at home, and does not interfere with the reading of telephone numbers even if it becomes dirty, and from the magnetic dial card. To provide a card dialing device that automatically dials a telephone number by reading it.

[Means for Solving the Problems] The magnetic dial card of the present invention has dots, letters, symbols, figures, etc. of magnetic material formed at predetermined positions on a substrate made of non-magnetic material, and a dial code can be determined depending on the shape and position of the dots, letters, symbols, etc. of magnetic material. What is expressed is a structural feature.

Further, the card dialing device of the present invention includes a magnetic reading means for reading the shape and position of a dot, a character, a symbol, etc. of the magnetic material of the magnetic dial card, and a dialing signal for outputting a dialing signal based on the read contents. The configuration is characterized in that it includes an output means.

[Function] The magnetic dial card of the present invention can be manufactured by, for example, writing dots on a paper card at predetermined positions with magnetic ink, so it can be distributed at low cost like a business card and can be easily manufactured at home.

Also, since it is not optical, there are no reading errors due to discoloration or dirt.

[Example] Hereinafter, the present invention will be described in more detail based on the example shown in the drawings. Note that this invention is not limited to this.

The magnetic dial card l shown in FIG. 1 has a company name, a department, a name, and a telephone number printed on a substrate 2 made of a non-magnetic material such as paper or plastic, and can be used as a business card.

The company name line and phone number line correspond to magnetic codes, and 1
One character or figure is one bit. In other words, 0 when a character or figure is formed with normal printing ink, and 1 when it is formed with magnetic ink.
It is designed to represent

Therefore, if this magnetic dial card 1 is read with a magnetic sensor using, for example, a semiconductor magnetoresistive element and a permanent magnet, it will be found that a dial code as shown in FIG. 2 is attached, for example.

For example, the magnetic ink has a particle size of 0.02 to 0.1 μm.
A mixture of fine particles of pure iron or γ iron in a cellulose binder at a weight ratio of 0.5 to 0.9 can be used.

Note that if the magnetic ink and the normal printing ink are the same color, the user will not be aware that a magnetic code is attached, and the aesthetic appearance will not be spoiled.

Next, FIG. 3 shows a magnetic dial card 1 according to another embodiment.

This magnetic dial card 1 has two company names and departments.

Dots 3 of magnetic ink are formed by transfer on the back side of a business card on which a name and telephone number are printed with ordinary printing ink. The position of dot 3 represents the dial code.

The gap between the magnetic head that reads the position of dot 3 is 1.
Since there is no problem in reading even if the size is about mm, a facial photograph 4 may be pasted on the back side and wrapped with a transparent film 5, as shown in FIG.

FIG. 5 shows a card dialing device 11 according to an embodiment of the present invention.
FIG. 6 is a flowchart showing the main part of its operation.

When the power of the card dial device 11 is turned on and the device 11 completes initialization, a standby display is displayed on the display section 12 (Sl).

Therefore, when the telephone optical magnetic dial card 1 is passed through the card league section 13, the card league section 13 reads the dial code (S2) and displays the dial number on the display section 12 (S3).

The line switching section 14 switches the changeover switch 15 from the dotted line side to the solid line side in the figure to connect the dial signal generation section 16 to the telephone line, and the dial signal generation section 16 turns on the line (
S4).

When the tone detection section 17 detects the line dial tone signal DT (S5), it outputs a dial transmission command to the timing signal generation section 18.

The timing signal generator 18 outputs a timing signal for dialing to the dial signal generator 16, and the dial signal generator 16 sends the dial number to the line (S
6).

Next, the tone detection unit 17 determines whether the tone signal from the line is a ringback tone signal RBT or a busy tone signal BT (S7), and if the RBTBT signal continues for 0 seconds (S8
), it is determined that the other party is away, and a line off command is output to the line off signal generating section 20.

The line off signal generation section 20 outputs a line off command to the dial signal generation section 16, and the dial signal generation section 16 turns off the line (S9).

After this, the power relay 21 is turned off, and the power is turned off (
S10).

On the other hand, if a BT signal is detected in the tone detection step $7, it is determined that the other party is busy, and a line off command is output to the line off signal generation section 20, and the line off signal generation section 20 generates a line off signal. is output to the dial signal generator 16, and the dial signal generator 16 turns off the line (Sll).

Next, it is determined whether or not the BT signal is detected for the third time (512).
), first or second serial dial signal generation unit 1
A redial command is output to 9.

The redial signal output unit 19 waits for 50 seconds.
3) Output a redial signal to the dial signal generator 16.

Thereafter, the operations from step S4 are repeated.

If the BT signal is detected for the third time, the power relay 21 is turned off, and the power is turned off (S10). In other words, you will have to give up on the dial.

When a normal business card or the like is set and dialed from the telephone T, the dial code printer 30 reads the dial signal and prints dots with magnetic ink on the set business card or the like to form a magnetic code corresponding to the dialed number. It is something to do. This makes it possible for ordinary households to easily produce magnetic dial cards.

For example, the magnetic code can be used to store a telephone number in a 4-bit BCD.
It may also be expressed in code.

It also adds parity according to the magnetic code, checks for reading errors, and dials in case of errors.

It is preferable not to do so.

Furthermore, if the DT double signal is not detected in step S5 of FIG. 6, a function may be added to display a line failure on the display unit 12 after, for example, 10 seconds have elapsed.

[Effects of the Invention] According to the magnetic dial card and card dial device of the present invention, the following effects can be obtained.

■Since magnetic dial cards can be produced at low cost, they can be distributed as business cards, pamphlets, and flyers. Also, it can be easily produced at home.

(2) Since it is magnetic and the gap between it and the magnetic head can be made large, it is resistant to stains and can be used to attach photographs, etc.

■Since it consumes less power than the optical type, it can also be powered by batteries.
