Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field to which the Invention Belongs] This invention relates to a ticket to be collected (which is referred to as a ticket collecting ticket in this specification) among the tickets inserted by a customer who enters from a ticket gate. The present invention relates to an automatic ticket gate equipped with a function of erasing the magnetic information recorded on the ticket collection ticket as a scrap ticket processing.

[Prior Art and its Defects] Most of the conventional automatic ticket gates are simply stored in a bill collecting box without erasing the magnetic information of a ticket determined to be a bill collecting ticket. There was a problem that the collected ticket was taken out and used illegally.

Among the information reading / writing magnetic heads provided on the ticket transport path, an automatic ticket gate is known in which the last magnetic head rewrites magnetic information to another content. When used for erasing, it is possible to erase only a part of the tracks of a plurality of lines of the ticket, so that the effect of completely preventing illegal use of the ticket collecting ticket cannot be obtained.
If all tracks are to be erasable, a new control circuit and wiring associated therewith and a major modification of the control method are required, resulting in a high equipment cost.

It is also conceivable to add a magnetic head dedicated to erasing the magnetic information of the bill collecting ticket between the reading / writing section and the allocating means, or after passing through the allocating means. However, when erasing using the magnetic head, It is necessary to pass the bill collecting ticket in contact with the magnetic head. Therefore, in consideration of preventing jamming of a deformed ticket, this magnetic head must be installed in the forced transport area. There are problems such as positional difficulty in mounting the head and reduction in processing speed due to extension of the transport distance.

Further, when a magnetic head similar to the read / write magnetic head is used, the demagnetizing force is weak, and it is difficult to completely erase magnetic information when the magnetic surface is on the opposite side.

[Object of the Invention] In view of the above points, the present invention provides a non-contact type erasing means consisting of a pair of permanent magnets between the sorting means and the bill collecting box under a predetermined condition. It is easy to secure a space without changing the transport length of the ticket transport unit, the number of magnetic heads in the read / write unit, or adding special elements such as a control circuit. An object of the present invention is to provide an automatic ticket gate that can completely erase the magnetic information of a ticket collecting ticket without causing a ticket jamming only by installing an erasing means.

[Embodiment of the Invention] Next, an embodiment of the invention will be described with reference to the drawings.

The automatic ticket gate according to the present invention sends a ticket inserted from the ticket slot 1 into the machine by the entrance transport section 2A, and the read / write transport section 2B serves as a magnetic head constituting the reading section.
The magnetic information recorded on the ticket is read by the corresponding magnetic head depending on whether the magnetic surface of the ticket is above or below by moving it between 3a, 3b and the pressers 4a, 4b, and not shown. The determination unit determines the ticket type and validity / invalidity based on the read information, and when the ticket is a non-billed ticket, the magnetic heads 5a and 5b and the pressing tool 6a that form the writing unit are used. ,
While traveling between 6b, write the necessary magnetic information, and if it is a ticket collection ticket, pass it without writing and read /
The ticket sent from the writing / transporting section 2B is driven by the sorting means 7 provided between the reading / writing transporting section 2B and the exit transporting section 2C in accordance with the ticket type determination result, If it is a bill collection ticket, it is distributed in the direction of the collection box 8, and if it is a non-collection ticket, it is distributed in the direction of the exit 9. An automatic ticket gate equipped with such sorting means 7 is known.

In the conventional machine, the tickets sorted by the sorting means 7 in the direction of the bill collecting box 8 fall freely in the space below the sorting means 7 and enter the bill collecting box through the guiding means such as a chute. It is designed to be stored.

In the present invention, attention is paid to the point that a space is provided between the sorting means and the bill collecting box, and utilizing this, the magnetic information erasing means 10 of the bill collecting ticket is installed in the space.

The erasing means 10 is composed of a pair of permanent magnets 10a, 10b which are arranged on both sides of the passage 11 through which the bill collecting ticket freely falls from the sorting means 7 and which are spaced from each other under predetermined conditions.

As shown in FIG. 2, the permanent magnets 10a and 10b have the same magnetic poles facing each other, and the direction of the magnetic force lines is directed toward the sorting means, and further, the sorting means side is wider than the bill collecting box side. It has been expanded and installed.

The pair of magnets are provided so as to be spaced apart from each other in the falling path of the ticket collection ticket in order to reliably apply the magnetic field to all the ticket collection tickets that naturally fall from the sorting means 7.

In this case, as shown in FIG. 3, a pair of magnets 10c, 10d
If the different magnetic poles are arranged to face each other, the magnetic force corresponding to the coercive force of the ticket falling between them, that is, the demagnetizing force necessary to erase the magnetic information recorded on the ticket cannot be obtained, Since the magnetic film of the ticket that falls between the magnets is attracted, the ticket is attracted to the magnets, which causes the jam of the ticket.

Further, as shown in FIG. 4, when a pair of magnets 10e and 10f are arranged in parallel with the same magnetic poles facing each other, the magnetic force concentration is low and a uniform and sufficient magnetic flux density cannot be obtained. Depending on the position or attitude of the ticket, it may not be possible to completely erase the magnetic information.

On the other hand, according to the present invention, as shown in FIG. 2, a pair of magnets 10a and 10b have the same magnetic poles opposed to each other and the magnetization direction is the direction of the ticket falling from the distribution means (the magnetization direction on the magnetic surface). ) Is further expanded so that the sorting means side is expanded, the first is that the vector of the magnetic force line acting as an attractive force is suppressed, so that the falling ticket is not attracted to the magnet and smooth. Secondly, since the magnetic force is highly concentrated and is parallel to the magnetization direction of the falling ticket, the vector of lines of magnetic force effectively acts on the magnetic surface of the falling ticket to completely demagnetize it. Magnetic information can be completely erased even from a ticket that passes through a wide contact area.

In addition, since a sufficient demagnetizing force can be obtained by arranging the magnets as described above, a permanent magnet can be used for the pair of magnets. Therefore, the erasing means can be easily mounted and a special installation space can be provided. Does not need

It is preferable to provide chutes 12 and 13 formed of a non-magnetic material on the facing surfaces of the magnets so that the bill collecting ticket from the sorting means 7 can smoothly and surely pass between the pair of magnets.

[Effects of the Invention] As described above, according to the present invention, the space is provided between the sorting means and the bill collection box, so that a new space can be created by simply replacing the chute of the conventional machine. Without needing
A means for easily erasing the magnetic information of the bid ticket can be provided. Further, the erasing means is a non-contact type in which a pair of permanent magnets have the same magnetic poles opposed to each other, and the magnetizing direction is made substantially coincident with the magnetizing direction of the bill collecting ticket so that the distributing means side is widened and installed. The magnetic information can be completely erased by sufficient demagnetizing force without causing a ticket jam. Therefore, it is possible to reliably prevent illegal use of the ticket collection ticket.
