When the call is finished, residual amount information is written in the card with the head 2d and the card is delivered to a return section 2f. On the other hand, if a call is made to a full of the recorded content of the card, the call is stopped based on a signal of residual amount =0 from the section 7.

Description

[Detailed description of the invention] The present invention relates to a magnetic card type congregation telephone.

2. Description of the Related Art In recent years, it has become common to sell products or provide services using cards with information about the amount recorded magnetically instead of cash.

Traditionally, public telephones have used Koi/ to collect call charges.

However, the coins are currently 10 yen, 3o yen, and 100 yen.
Three types of circles can be used, but long-distance calls can be made at low #
l: Performing F-in requires a large amount of coins, which is inconvenient for the user. Additionally, since the carp must be collected, there is a problem with the bank that requires collection personnel.

The present invention has been made in view of the above-mentioned points, and it compares the amount information provided by the magnetic card with the call fee information obtained from the telephone, and controls the telephone call according to the comparison result. To provide a magnetic card type public telephone that performs calculations, writes the recorded contents of a magnetic card, and returns it.

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

FIG. 1 shows a circuit configuration of an embodiment of the present invention. In the figure, l is a telephone and - is a magnetic card handling device! Both are controlled by the main control section J. This main control section J is connected to the telephone set 1 through an interface reference, obtains a handset up/down signal and a subtraction signal corresponding to the call charge from the telephone set 1, and provides a one-call on-off signal and an alarm signal to the telephone set. In addition, the main control section J is a card control section! and a magnetic card handling device B by a magnetic head control unit B. The card control section j sends and receives control signals to and from the main control section J, and also receives a card insertion signal from the card detection part a of the card scattering device and a card built-in signal from the card detection section. , and obtains a card full signal from the card detection section Jh, and gives a card control signal to the control section 1 of the card handling device.

The magnetic head control section 10 also exchanges control signals and key suites with the main control section J, and exchanges data with the magnetic head section d of the card handling device 7. The memory calculation section 7, which exchanges amount data between the main control section J, receives a subtraction signal, an addition signal, and a clear signal from the main control section J, gives a signal regarding the remaining amount, and provides the amount data to the display section r.

The display section r is also given an alarm signal from the main control section J in addition to this. The power supply circuit receives control signals from the main control section J and charge signals from the interface J, supplies power to the above-mentioned sections, charges the battery, and provides a battery alarm signal to the main control section.

FIG. 2 (IL), (1)) shows the card processing mechanism of the magnetic card handling device, where FIG. 2 (IL) is a front view and FIG. 2 (1) J is a side sectional view thereof. This mechanism consists of the top and bottom of the magnetic card 100 inserted from above in the figure.
It detects whether the front or back side is correct, and if it is normal, moves the magnetic card 100 to the information reading/writing position, reads the data and writes after the call, and then places the magnetic card 100 in the card return section or card storage section shown below. It causes the cards to fall.

The magnetic card 100 is preferably approximately rectangular and relatively rigid; for example, it is made of synthetic resin. And approximately at the center in the longitudinal direction.

A magnetic stripe is provided in the width direction, that is, in the direction perpendicular to the longitudinal direction. One corner of the magnetic card 10O, the lower left register in the figure, is cut out in a triangular shape. This cut-off portion is preliminarily cut into a ξ-thin shape, and is cut by the user when using the magnetic card ioo. As a result, when the magnetic card 100 is inserted into the card processing mechanism, it is possible to know whether the magnetic card is top or bottom, front or back, depending on whether the triangular cutout is located at the lower left corner as in the case shown.

The card processing mechanism is located in the card insertion slot l above the housing.
C1 (corresponding to C in Figure 1)) Below the card ejection port tiC
(corresponding to Cf and Cg in Fig. 1), and an information measuring/writing part 1lb (corresponding to 10 in Fig. 1) in the center.

And card insertion slot//IL and Jo @WIIFJ writing department/
A rotary receiving plate 11 is provided between the information P taking/writing part//b and the card ejecting port/10, and a rotating holding/returning plate/3 is provided between the information P taking/writing part//b and the card ejecting port/10.

In the information reading/writing part//b, in order to correctly align the magnetic stripe of the magnetic card 100 with the writing position, there is a member lhiro that pushes the magnetic card ioo in the width direction and a member lhiro that pushes the magnetic card /DO from the back side. It has a movable wall /j to push. These members /G and movable wall /j are driven by a motor MO, together with a receiving plate 1 and a holding and returning plate /3. The recorded information of the aligned magnetic card 100 is retrieved by a magnetic head d provided on the rotating arm 14,
Also, the single rotation arm/6 that writes information is the motor MO.
, is driven by.

To operate the receiving plate 1, holding/returning plate/3° member/4m and movable @/3 with a single motor MO,
2 and the holding/returning plate 13 are shifted by a predetermined angle and attached to the same rotating shaft, and the holding/returning plate/3 is attached to the above rotating shaft so that the movable car @tS approaches the magnetic head controller. The movable wall 15 may be pushed by a provided cam or the like, and the switching plate 17 driven by the solenoid 80I is in the solid line position shown in FIG. Position it as shown by the broken line.

The magnetic card after being processed by the information cutting and writing section llb is sent to the cart discharge port l/C. The card ejection port/10 has a return ejection port and a storage ejection port which are cut off by a relocation type switching plate 17 driven by a solenoid SQL. The return outlet is for returning the magnetic card to the phone user, and should only be used if there is balance information on the magnetic card. The storage outlet is for taking in a magnetic card, and is used when there is no balance information on the magnetic card.

This card processing mechanism is provided with various switches for the purpose of detecting operations of various parts for card processing operations. First, in order to detect the magnetic card 100, the receiving plate l:t
Photoelectric switches 8W, L, eV, and R are provided slightly above the holding and returning plate 13, and a photoelectric switch SW is also provided slightly above the holding and returning plate 13.

Also, a switch By is provided to detect the operation of the receiving plate 12.

A switch 5Vll is provided to detect the operation of the movable tLS, a switch SV is provided to detect the operation of the holding return plate 13, and a switch 8W! is provided to detect the operation of the rotating arm/6.

Fig. 3 and Fig. J are time charts showing the operation of each part of one embodiment of the present invention, including the operation of each of these switches. Fig. 3 is a time chart during normal operation, and Fig. It shows when calls were made until the amount reached the same amount as the amount information.

The operation of the above embodiment will now be explained. Here, νSW that does not appear in each of the above figures but appears for the first time in the jgl and reference figures.
is a switch that produces an output when the handset is lifted from the telephone.

If the handset is picked up from the telephone now, I'll be surprised.
v is turned on and the main control unit 3 is connected via the interface terminal.
A pick-up signal is given to the receiver.

In this state, when a card is inserted into the card receiving part B of the magnetic card handling device, the photoelectric switches BY, L, eV, and R of the card detector core A detect it. In this case, it is assumed that the magnetic card is correct and has been inserted in the correct orientation, and the photoelectric switch B and R are shielded from light and produce an output, and eV and L are given light, so there is no output. . The card insertion signal with this kind of content is the cart ° control part! This gives the card control section! sends a card control signal to the control unit KO1 to take in the card, turns the motor MO 1, rotates the receiving plate 12 and the return holding plate /J, and moves the movable wall 15 (0 member /4). As a result, the magnetic card that was stopped at the acceptance board/J position! is moved to the holding return board 1.
The magnetic card lOO is then lowered to position 3, and then aligned so that the magnetic stripe of the magnetic card lOO covers the magnetic head.

During this time, the photoelectric switch SV is shielded from light and produces an output,
Then, upon detection of the receiving plate /:l, the switch SW,
When the movable wall /j is detected, the switch 8W1 is operated, and when the holding return plate 13 is detected, the switch SV is operated. Among these, the output of the photoelectric switch SVs is sent from the card detection section 2e to the card control section! The control unit KO1 is used as a violet signal in the card to drive the motor MO.

Next, the card control unit j rotates the rotating arm/
A rotation command A, that is, a drive command for the motor MO, is given to cause the rotation arm 16 to move from the left to the right in the figure and then back to the left. During this time, the magnetic stripe of the magnetic card is read by the magnetic head section d, and evaluation data is given to the magnetic head control section t. Then, the read data is divided into key code and amount data by the magnetic head control section t and given to the main control section J and the F information calculation section 7, respectively.

During the operations up to this point, if the card is not read normally, it is determined that there is an abnormality and the card is returned. The return operation is the same as the return when the caller ends the call and has the remaining amount, and this will be explained further below.

The main control unit 3 is given a key code, and the memory calculation unit 7
A signal indicating that the remaining amount is not O is given from the terminal, and a signal to turn on the communication circuit is sent to the inter-7 Aceda, which connects the continuous line of the telephone 1.

On the other hand, the storage calculation section 7 supplies the amount data to the display section t to display the amount recorded on the magnetic card.

This is the station where a call can be started.

When the call started, the telephone 1 sent an e/! A subtraction signal is given to the storage calculation section 7 via the -7 Aceda and the main control section 3, the remaining amount is calculated, and the remaining amount is displayed on the display section l. This is the outline of operation mode (■).

The device of the present invention performs different operations depending on whether or not the amount of money on the seven magnetic cards is sufficient until the call ends. Figure 3 shows the former, and Figure 3 shows the latter. Therefore, first, FIG. 3 will be explained, and then FIG.

First, in the case of Fig. 3, when the handset switch SW is turned off due to the end of the call, the card control section is activated. gives a rotation command for the rotation arm/6, that is, a drive command for the motor MO, to the control unit KO1, and moves the rotation arm 14 from the left to the right in the figure, and then back to the left twice. let During this time, the recorded contents of the magnetic card are re-recorded by the magnetic head unit COd.
Erasing and writing of sand amount information are performed.

At the time when writing is performed, the main control section 3 gives a clear signal to the storage calculation section 7 to set the memory contents to O.

Also, since the rotating arm/6 has returned to its original position, the switch 87. He turned on the card control department! By giving a control signal to the control unit 1 and rotating the motor IMO, the holding and returning plate 13 is operated and the magnetic card is dropped. The switching plate 17 on this falling path is the solenoid S.
If QL is not energized, there is a recess in the position that opens the card return slot.In this case, solenoid EIOL is not energized, so S
The Qi card falls into the return slot.

The motor MO continues to rotate further and returns the movable @/3 and the member IQ to their original positions, thereby ending the operating mode (2).

Next, in the case of FIG. μ, a magnetic card is additionally inserted at the call starting edge. Additional insertion of a magnetic card is possible only after the amount information of the already inserted card has been read. When an additional card is inserted, switch 8W in the card insertion slot,
L, B'W, and R detect the card, and this detection signal is sent from the card detection section core a to the card control section! Card control section given to! rotates the motor MO through the control unit 1 to operate the receiving plate /j, the holding/returning plate 13, the member /44, and the movable @/j.

As a result, the glossy card is released from the blocking by the receiving plate/2, reaches the position of the holding/returning plate 13, is detected by the switch SV, and is pressed to a predetermined position for reading more recorded information.

On the other hand, due to the insertion of the additional card, the card control section j energizes the solenoid 80L via the control section Ko1 to close the switching plate 1.
7 is indicated by the broken line in FIG. 1, and the inserted card that has fallen due to the rotation of the holding return plate 13 is taken into a card storage chamber (not shown).

When the additional insertion card is placed in the predetermined position, the card control unit j controls the motor MO,
is activated to rotate the rotating arm/1 and read the F record information. This read data is sent from the magnetic head code d to the magnetic head control section 4, and the key code is sent to the main control section 3.
The amount data is sent to the storage calculation section 7. Memory calculation unit 7
calculates the amount by adding the amount data of this additionally inserted card to the data of the already inserted card and displays it on the display section r.

This is the operation mode 1, and thereafter the operation mode shifts to the operation mode 2.

The above is a case where the call ends within a range that does not exceed the amount information recorded on the card. On the other hand, if a call is made until the card is full, the main control unit 3 sends the remaining amount = O signal from the storage calculation unit 7 and connects the call line to the telephone @/ via the interface card. Gives an off signal to stop one call.

In this case, the card is not likely to be used again, so it is taken into the card storage section, but only returned when the card storage section is full. It is of course possible to turn the no-call mode on again if an additional card is inserted after this.

Although not mentioned in the operation explanation above, if there is a mischief that is common with public telephones, for example, if the receiver is picked up and down many times and the call does not take place, the main control section J will give an alarm signal to the display section t. Displays information including warnings! l display l#-
1. Of course, failures due to other causes of the telephone may also be dealt with.

As described above, the present invention constitutes a public telephone that uses a magnetic card to make calls, so it is possible to provide a public telephone that can eliminate the problems associated with conventional coin-operated public telephones.
