ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus and a method for issuing a ticket of the type used to identify a person entitled to board a plane, ship or train. More particularly, it relates to an apparatus for removing a ticket from an elongated rectangular ticket sheet consisting of a plurality of tickets separated by perforations, and issuing the ticket to a purchaser.
An apparatus for cutting a ticket from such a ticket sheet and issuing it is disclosed in Japanese patent application number 7-223348 (Publication number 9-67061 published Mar. 11, 1997) and shown in FIG.
7
. Referring to
FIG. 7
, an elongated rectangular ticket sheet
1
is illustrated which consists of a plurality of tickets
3
,
3
′,
3
″ connected end-to-end by transverse lines of perforations
2
,
2
′ which permit each ticket to be separated from the ticket sheet
1
for conveyance to a customer. In this prior art apparatus, the ticket sheet
1
is fed by a first feed means
30
along a feed passage (not shown) to a cutting part
400
of the apparatus. A second feed means
50
is positioned downstream from the cutting part
400
, and a cutting roller
500
is interposed between the first and second feed means
30
and
50
at the cutting part
400
. The feed means
30
and
50
are rotated at different speeds, the rotational speed of feed means
50
being greater than that of feed means
30
.
The cutting roller
500
, which is shaped somewhat like a bead of an abacus, consists of an axle
510
and a surface
520
formed of two conical portions
520
a
and
520
b
having a common base
520
c
at the center thereof. The circumferential surface of the common base
520
c
forms the cutting edge of the cutter roller
500
. The base
520
c
has a greater diameter than the remainder of the surface
520
of roller
500
, and functions as the cutting portion of the roller.
In operation, the leading edge
1
′ of the ticket sheet
1
is inserted in feed means
30
and conveyed by rotation of feed means
30
to the feed means
50
. When the leading edge
1
′ of ticket sheet
1
reaches the feed means
50
, rotation of feed means
30
is stopped, rotation of feed means
50
is started, and the leading edge
1
′ of ticket sheet
1
is conveyed by rotation of feed means
50
to the position shown in FIG.
7
. When the line of perforations
2
separating ticket
3
from ticket
3
′ reaches the cutting roller
500
, rotation of feed means
30
is restarted at a slower rotational speed than that of feed means
50
. Because the rotational speed of feed means
50
is greater than the rotational speed of feed means
30
, and because the perforations
2
of ticket sheet
1
are pressed against the cutting roller
500
, the ticket sheet
1
is stretched around the perforations
2
from both sides.
The cutting edge at common base
520
c
of the cutting roller
500
makes a shallow cut in the perforations
2
and a small diamond-shaped opening is formed in the center of the perforations. As the power for pulling the ticket sheet
1
is further increased, the diamond-shaped opening is ripped along the perforations
2
and the diamond-shaped opening is extended gradually. As a result, the ticket
3
is separated from ticket
3
′ of the ticket sheet
1
.
However, a problem encountered with this prior art apparatus is that the ticket
3
is not always cut completely along the perforations
2
. Consequently, it sometimes occurs that a scrap of paper is left on both edges of the separated ticket
3
although the center part of the perforations
2
has been cut clearly. If a scrap of paper is left in an edge of the separated ticket
3
, it may become jammed in a feed passage of the ticket issuing apparatus. Also, the ticket may not have a neat appearance which could cause a customer to question whether it is genuine.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide a ticket issue apparatus which issues a high quality ticket cut with precision from a ticket sheet.
Another object of the invention is to provide a ticket issue apparatus which issues a ticket without jamming the apparatus.
The present invention is an apparatus for separating a ticket from a ticket sheet containing a plurality of tickets, each of the tickets being separated from an adjacent ticket by a line of perforations. The apparatus includes a cutting part having a feed passage, first and second spaced feed rollers positioned within the cutting part for conducting the ticket sheet along the feed passage, and a cutting roller positioned within the cutting part between the first and second feed rollers for cutting a ticket sheet at a line of perforations.
The cutting roller includes an axle and a surface having first and second ends surrounding a length of the axle. The surface of the cutting roller includes a central portion having a first diameter forming a first cutting edge on a circumference thereof, and further includes at least first and second outer portions. The first outer portion is located between the first end of the surface and the central portion, and the second portion is located between the second end of the surface and the central portion. Each of the first and second outer portions has a second diameter which is less than the first diameter and forms a second cutting edge which is smaller than the first cutting edge.
Drive means are provided for driving the first and second feed rollers at predetermined speeds to bring a line of perforations on the ticket sheet into engagement with the cutting edges of the cutting roller, and a controller is coupled to the drive means for controlling the speed at which each of the feed rollers is driven. The feed rollers are driven at different speeds so that parts of the ticket sheet on opposite sides of the line of perforations are pulled in opposite directions while the line of perforations is cut by the cutting edges of the cutting roller thereby separating a ticket from the ticket sheet.
