DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a separating mechanism for an automatic ticket gate that processes a plurality of media, and more particularly to a separating mechanism for separating a plurality of media having different sizes such as a ticket and a commuter pass. About.

[0002]

2. Description of the Related Art Recently, automatic ticket gates have been developed in which in order to prevent unauthorized use of a ticket and a commuter pass, the ticket cannot be exited unless the commuter pass and the ticket are inserted at the same time. Also, if you board from an automatic ticket gate that cannot use a stored fair card (SF card), purchase a ticket and use the SF card at the disembarkation station to leave the automatic ticket gate. If you do not put in at the same time, you can not pass through the automatic ticket gate.
In this way, when a plurality of media having different sizes consisting of a commuter pass and a ticket or an SF card and a ticket are inserted into the ticket slot of the automatic ticket gate, the subsequent processing of the media must be performed one by one. Therefore, a separating mechanism for separating a plurality of media overlapping on the downstream side of the ticket slot is provided in the automatic ticket gate.

It comprises a separation belt 102 and a transport belt 104 for transporting the medium. The separation belt 102 is configured to rotate in a direction opposite to the conveyance belt 104.

Next, the operation of the separation mechanism shown in FIG. 5 when the large medium C1 having a large size is located on the upper side and the small medium C2 having a small size is located on the lower side will be described with reference to FIG. .

In FIG. 6A, even if the large medium C1 reaches the separation unit S first, the large medium C1 is equivalent to one medium due to the conveying force of the conveying belt 104 located below. Therefore, it is transported as it is.

As shown in FIG. 6B, when the small medium C2 reaches the separation section S, the thickness of the medium C1 and the small medium C2 becomes two, and the separation belt 102 rotates in the reverse direction. Therefore, the upper large medium C1 is stopped without being transported, and only the lower small medium C2 is transported. This transport
The frictional force between the large medium C1 on the upper side and the separation belt 102 rotating in the reverse direction is equivalent to two sheets of the medium, and the separation belt 102
Is a rubber belt, the large medium C1 and the small medium C
2 is small because it is a frictional force between the media.
The transport force of the lower transport belt 104 causes the small medium C2
Only the large medium C1 is conveyed while rubbing.

In FIG. 6C, when the small medium C2 passes through the separation section S, the large medium C1 becomes one sheet in the separation section S, and the large medium C1 is conveyed as shown in FIG. As shown in FIG. 6E, the large medium C1 and the small medium C
In a state where the two are not completely separated from each other, the two are double-fed, so that it is not possible to process the ticket one by one, which is inconvenient.

The reason why the large medium C1 and the small medium C2 are conveyed in an overlapping state without being separated is that the large medium C1 is located on the upper side and the small medium C2 is located on the lower side as described above. When the small medium C2 is in the large medium C1.
Is not transported without being separated as described above.
