Description

[Detailed Description of the Invention] The present invention relates to a magnetic card reader device used in card-type public telephones, etc., which enables telephone calls by inserting a magnetic card, and in particular, the present invention relates to a magnetic card reader device used in card-type public telephones, etc., which enables telephone calls by inserting a magnetic card. The present invention relates to a magnetic card reader device that prevents cards from being taken in in the reverse direction.

For example, in public telephones that allow calls by inserting a magnetic card, a magnetic card reader device is installed inside the phone housing, and when the magnetic card is inserted into the card slot, the magnetic card is taken into the card path, and the card runs. A magnetic head installed at a predetermined position on the card path reads the magnetic information recorded on the magnetic card to enable a call, and after the call ends, the tip of the magnetic card protrudes outward from the end of the card path. The vehicle is then sent to the return passageway.
During the reading and rewriting, the magnetic card moves back and forth to the magnetic head position several times in both forward and reverse directions.

However, in the conventional magnetic card reader device of this type, as shown in FIG. It is continuous with 3a at the same height. Therefore, if the user forgets to remove the magnetic card A from the card return slot 1 after the end of the call, when the next user uses the phone, the conveying device 4 will reverse the magnetic card in the card running path 2. The rear end of the magnetic card A, which was left in the return passageway 3 due to forgetting to take it out, was transferred to the conveyor belt 4 wrapped around the drive roller 41 at the end of the card running path 2a.
2 and the pressure contact roller 43, and the card is taken into the card running path 2. In addition, if the magnetic card that you forgot to remove remains in the return passageway 3, when the next magnetic card is sent out, the end part 2a of the card running path and the innermost part of the return passageway 3a will be on the same plane. Because they are continuous, they collide and cause problems such as card jams. Furthermore, if a card-shaped object is inserted through the card return slot 1 by mischief or the like, there is also the drawback that it is taken into the card running path 2.

This invention was made based on the above circumstances, and its purpose is to prevent magnetic cards that have been forgotten to be removed from the card return slot or card-like objects that have been inserted into the card return slot due to mischief etc. To provide a magnetic card reader device which does not get taken into a running route and which allows a plurality of subsequent magnetic cards to be accumulated in a card return slot even if a magnetic card that has been forgotten to be removed remains. .

An embodiment of the present invention will be described below with reference to FIGS. 2 to 4.

FIG. 2 is a schematic diagram showing the overall configuration of the magnetic card reader device 12 of this embodiment incorporated into the housing 11 of a public telephone.

In the figure, 13 is a card insertion slot, 14 is a card running path, 15 is a return passageway, 16 is a card return slot, 1
7 is a magnetic card A inserted into the card insertion slot 13
is taken in and conveyed along the card running path 14, and conveyed in forward and reverse directions at the position of the magnetic head 29,
It is a conveying device that sends the device to the return passageway 15 when the call ends, and is attached to pulleys 18a to 18c and a tension roller 22a, and is attached to a pressure roller 20.
The conveyor belt 19a, pulley 18c,
18d, drive roller 21, tension roller 22
Conveyor belt 19b attached to b, pulley 1
8e, 18f, roller 23, tension roller 2
2c and a conveyance auxiliary belt 19c facing the conveyance belt 19b.
A pressure roller 24 is installed so as to be in pressure contact with the conveyor belt 19b. Then, at the end portion 14a of the card running path, the upper conveyor belt 1
A card guide 25 is provided below 9b. This card guide 25 is provided so that the upper conveyance belt 19b is bent diagonally downward from the pulley 18c (that is, toward the return port), and is sandwiched between the conveyance belt 19b and the conveyance auxiliary belt 19c. The leading end of the magnetic card that has been conveyed is brought into contact with the card guide 25 and guided.

This card guide 25 protrudes from the pressure roller 24 below the drive roller 21 toward the return port passage 15 side, and at its terminal end 25b, there is a stepped portion 2 that suddenly drops into the innermost part 15a of the planar return port passage 15.
5a is formed.

From the end of the card running path 14a to the return exit passage 15
On the side, a coil spring 28 applies a rotational force that presses against the return card guide plate 27 forming the return port passage 15.
A restraining lever 28 provided by a is provided. When the magnetic card A is conveyed from the end portion 14a of the card running path toward the card return slot, the holding lever 28 is moved by the magnetic card A by the thickness of the magnetic card against the rotational force of the coil spring 28. Although the tip portion 28b is pushed away, the pressure reduces the conveyance speed of the magnetic card and prevents the magnetic card A from flying out into the card return slot.

FIG. 3 shows an example of a specific configuration of the card guide 25. As shown in FIG.

In FIG. 3, reference numerals 31 and 32 denote opposing side plates for forming a frame body to which the pulleys 18e and 18f to which the lower conveyance auxiliary belt 19c is attached, the pressure roller 24, etc. are attached.
A card guide 25 is rotatably attached to a shaft 33 spanning between the two. Card guide 2
5 consists of two parallel side plates 34, 34 of the same shape, which are fixed together by horizontal rods 35, 35. The upper portions 25c of the side plates 34, 34 extend toward the pulleys 18e, 18g, and the terminal portions 25c extend toward the pulleys 18e, 18g.
5b, the stepped portion 25a is formed as described above.

In FIG. 3, reference numeral 36 denotes a support member that rotatably attaches the pressure roller 24 to the shaft 33, and 37 denotes a coil spring that applies rotational force to the pressure roller 24 in the direction of the drive roller 21.

In the above configuration, when the magnetic card A is inserted into the card insertion slot 13, the magnetic card A is conveyed along the card running path 14 while being held between the conveyor belt 19a and the pressure roller 20, and then the magnetic card A is conveyed along the card running path 14 by the conveyor belt 19b and the conveyor auxiliary belt 19c. The magnetic head 29 reads, rewrites, and confirms the magnetic information while the magnetic head 29 reciprocates downward and upward several times, and when the call ends, it is transported toward the return slot. At this time, the magnetic card A is held between the pulleys 18d and 18f and sent out downward, the leading end of the magnetic card A contacts the card guide 25, and is held between the drive roller 21 and the pressure roller 24, It is sent out to the return passageway 15, pushes aside the holding lever 28, and advances so that its rear end reaches the return passageway 15 as shown in FIG.
It is located at the innermost part 15a of the
8, the card is pressed against the return card guide plate 27.

Therefore, the stepped portion 25a at the end of the card guide 25
Accordingly, the rear end of the magnetic card A is located at a predetermined height apart from the driving roller 21 and the pressure roller 24 that constitute the card running path terminal end 14a.
Therefore, even if the user forgets to remove the magnetic card A from the card return slot 16, the magnetic card A will not be taken into the card running path 14 during reverse transport by the conveying device 17.

Also, as mentioned above, the magnetic card A is in the return exit passage 1.
5, the cards are sent out obliquely from above to below, so the holding lever 28 is pushed aside and a plurality of cards can be accumulated in a stacked state within the height of the card return slot 16, as shown in FIG.

Further, even if an attempt is made to push the magnetic card into the card running path 14 in the state shown in FIG. 2, the magnetic card is prevented from entering the card running path 14 because it comes into contact with the stepped portion 25a.

As explained above, in the magnetic card reader device according to the present invention, the card running path end portion 14a
In addition, since the stepped portion 25a having a predetermined height with respect to the return port path 15 is provided, a magnetic card that has been forgotten to be removed from the card return port 16 is prevented from being taken into the card running path 14 when being reversely transported by the conveying device 17. Furthermore, even if there are still magnetic cards that have been forgotten to be removed, they can be stored in the card return slot, and even if a card-shaped object is inserted by mischief, it will not be taken into the card running path 14 because it will come into contact with the stepped portion 25a. It has many advantages, such as not being damaged.
