Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a media separating apparatus for an automatic ticket gate that separates stacked media such as a ticket into one by one. 2. Description of the Related Art In recent years, for the convenience of users, a plurality of tickets, such as an express ticket and a regular ticket, or a disembarkation ticket and an advance ticket, are stacked on the main body of an automatic ticket gate. Automatic ticket gates that can be loaded all at once have been proposed. [0003] As described above, even in a batch-type automatic ticket gate, reading or writing, printing, or punching of data recorded on a ticket is performed for each ticket, so that batch-type automatic ticket gates are used. The tickets are separated one by one in a medium separating device (hereinafter, referred to as a “separating device”) provided in the main body of the automatic ticket gate. FIG. 2 shows that the present applicant has previously filed Japanese Patent Application No. 8-34.
No. 3112, a separation device for an automatic ticket gate suitable for being incorporated into a batch input type automatic ticket gate (hereinafter referred to as a “separation device ”).
Device. " ) Is a schematic diagram of a. [0005] The separation apparatus 10 according to the above proposal is provided between the take-in transport path 2 and the alignment transport path 3 provided inside the slot 1 of the main body of the automatic ticket gate (not shown). That is, the separating device 10 is composed of a fixed block B at the center and a pair of feed rollers 10a and 10b provided on both sides of the block. The block B has a flat surface on the upper surface, and the position of the surface coincides with the transport position of the ticket (not shown), and the gap (interval) of one ticket upward from the surface. G is provided with a reverse rotation roller R that applies a conveying force to the ticket in a direction opposite to the conveying direction of the ticket. The feed rollers 10a and 10b are driven to rotate in a direction in which the ticket can be transported from the take-in transport path 2 to the aligned transport path 3, respectively.
, P2 so that the ticket can be pressed toward the feed rollers 10a and 10b, respectively. The operation of separating a ticket in the proposed device having the above-described configuration will be described with reference to FIG. Here, an example is described in which two tickets (in FIG. 3) are stacked and put together. In FIG. 3A, two tickets are used.
Is sent to the block B side by the feed roller 10a,
Up to the gap G, two tickets are conveyed. As shown in FIG. 3B, when the two tickets reach the gap G, the gap G becomes
Since there is no room for two tickets, the tip of the upper ticket abuts on the reverse roller R. Therefore, the upper ticket receives the force returned to the upstream side (the feed roller 10a side) by the rotation of the reverse rotation roller R, and is prevented from being transported to the downstream side (the feed roller 10b side). Since the gap G has a gap into which one ticket can enter, as shown in FIG. 3C, only the lower ticket is conveyed toward the feed roller 10b by the rotational force of the feed roller 10a. You. When the lower ticket passes through the gap G, the overlapping state of the upper ticket and the lower ticket is released, as shown in FIG. Next, the upper ticket enters the gap G and is conveyed toward the feed roller 10b by the rotational force of the feed roller 10a. The above separating operation is performed by two tickets,
Are stacked, but when three or more tickets are stacked, they are similarly separated one by one. In other words, the ticket transmitted from the lowest ticket to the gap G side is 1
Separated one by one. [0015] As described above, the separation device according to the above-mentioned proposal has a feed roller with a pinch roller before and after in the conveying direction of a gap for one medium (ticket). Since each is provided, it has the feature that the stacked media can be effectively separated one by one.
The surface of the feed roller is made of an elastic material made of synthetic rubber or the like, similarly to the roller with a pinch roller provided in a known medium transport device, and the peripheral surface thereof is formed flat. If oily dirt or the like adheres to the surface of the film, the feeding effect may be impaired. The present invention has been made in order to solve the above-mentioned drawbacks, and provides a separation apparatus capable of maintaining a medium feeding effect even when a dirt substance adheres to the surface of a feeding roller. It is in. In order to achieve the above object, a separation device according to the present invention includes a feed roller with a pinch roller before and after a gap having a thickness of one medium in the conveying direction. The plurality of media stacked by one of the feed rollers are sent to the gap side, and the plurality of media stacked through the gap are separated one by one. In a separation device in which the discharged medium is sent by another feed roller in a direction away from the gap, the separation medium is formed on the surface of the two feed rollers by grooves in a direction perpendicular to the rotation direction.
Rutotomoni provided made the concavo-convex respectively, the gap
Between the groove of the roller located in front of the short and long
It is characterized in that grooves are formed at unequal pitches . Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic configuration diagram when a separation device according to an embodiment of the present invention is applied to an automatic ticket gate that supports a plurality of sheets. The same components as those in FIG. 2 are described using the same reference numerals. The separating device 1 includes a take-in transport path 2 having a take-in roller 2a provided inside an input port 1 of a main body of an automatic ticket gate (not shown), and a way to transport a ticket (not shown). And an alignment transport path 3 that makes one side of the ticket abut on a substrate (not shown) so that the attitude of the ticket is kept constant. The separating device 1 comprises a fixed block B at the center and a pair of feed rollers 4a and 4b provided before and after in the transport direction of the block (upstream and downstream in the transport direction). Have been. The block B has a flat surface on the upper surface, and the position of the surface coincides with the transport position of the ticket, and information from the surface indicates the gap (interval) G of one ticket.
And a reverse roller R for applying a conveying force to the ticket in a direction opposite to the conveying direction of the ticket. The feed rollers 4a and 4b are rotationally driven by motors (not shown) in a direction in which the ticket can be conveyed from the side of the take-in conveyance path 2 to the side of the alignment conveyance path 3, and are also driven by pinch rollers P1 and P2. Can be pressed toward the feed rollers 4a and 4b, respectively. The outer circumferences of the feed rollers 1a and 1b are made of an elastic material such as synthetic rubber, and have a large number of grooves 4 ', 4' Are provided, and the surface is formed unevenly. Among the feed rollers 4a and 4b, the interval between the grooves 4 'of the feed roller 4a located on the upstream side of the block B is as follows.
As shown in FIG. 1, a groove line of the unequal pitch ing a sequence of relatively short intervals two relatively long intervals, also, spacing the grooves 4 'of the feed roller 4b on the downstream side of the block B It includes a groove line of equal pitch ing a sequence of relatively short intervals

The separating operation of the stacked tickets in the separating device 1 having the above-described structure is the same as the separating operation described with reference to FIG. 3, and the description thereof is omitted. In the above example, both feed rollers 4a,
Although the shape of the unevenness on the surface of 4b is made different, both can be made the same. However, when the unevenness of the feed roller 4a on the upstream side of the block B is formed to have a protrusion having a relatively wide interval, wear can be reduced. That is, since the stacked ticket is located on the upstream feed roller 4a side, the downstream feed roller 4a
This is because the load becomes larger than b. The irregularities on the surfaces of the feed rollers 4a, 4b are formed by the grooves 4 ', 4', but, for example, holes may be provided on the surface at predetermined intervals. As described above, since the surfaces of the feed rollers 1a and 1b have irregularities, temporarily the feed rollers 4a and 4b
