Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates generally to a valuable ticket and a ticket printer and, more particularly, to a valuable ticket in which ticketing data is magnetically recorded and printed and a ticket printer for issuing such a ticket by recording and printing ticketing data on it.




In airline and other industries, a reservation and ticketing system for airline or other tickets, called a computer reservation system or CRS for short, has been built up so as to deal with intensive passenger-conscious services. A problem of vital importance for such a system designed to accommodate to a recently increasing number of passengers is to make its services (for reservation and fare adjustment) efficient.




For that reason, the introduction of airline tickets provided with magnetic stripes so as to control these services in bulk, called automated ticket/boarding pass or ATB for short, is now spreading drastically. These tickets are required to have high storage stability of printed data and to have the ability to be printed easily as well. A ticket printer for them, on the other hand, is required to make ticket management easy and to render ticketing less time- and labor-consuming as well.




2. Description of the Related Art




Tickets issued from a conventional ticket printer have made use of plain paper and been printed on wire-dot, electrophotographic and other printing systems. The wire-dot printing system involves some grave problems such as (1) loud noise, (2) low print resolution and (3) slow printing speed, and the electrophotographic printing system has again some serious problems such as (1) an increase in hardware size, (2) a rise in hardware cost and (3) susceptibility to environmental changes (printing is difficult at high humidity in particular). In recent years, hardware working on a thermal-dot printing system making use of a heat transfer ink ribbon has been developed.




This thermal-dot printing system making use of a heat transfer ink ribbon makes no noise, has a high print resolution and a high printing speed, achieves reductions in hardware size and cost and dispenses with any maintenance, and so lends itself well to issuing airline tickets.




However, some serious problems with the conventional thermal-dot printing system making use of a heat transfer ink ribbon are that (1)the heat transfer ink ribbon costs much and incurs some considerable expense for maintenance, and (2) the heat transfer ink ribbon is troublesome to handle, because it must be replaced by new one whenever a certain number of prints are obtained.




Consequently, it is now desired to use printing hardware working on a direct thermal printing system—in which case heat-sensitive paper is directly printed—and making no use of any heat transfer ink ribbon. In the case of airline tickets that are a sort of securities, however, there are the following problems.




(1) Generally, the thermal-printing paper is a paper that is obtained by coating a heat-sensitive layer comprising a leucodye, a color developer and a binder onto a paper substrate at a thickness of a few μm. When heated by a thermal printing element, the leucodye and color developer are fused to give rise to a color-developing chemical reaction. However, this color-developing zone, when stored over an extended period, disappears, thus rendering the thermally printed paper invaluable.




(2) A printed thermal-printing paper, when coming into contact with an organic solvent such as alcohol, a plasticizer and oils and fats, breaks up the chemical reaction, causing the color-developing zone to disappear.




Conventional airline ticket printers have been broken down into two types, one in which a stock of precut ticket blanks are fed out one by one for magnetic recording and printing, and the other in which a stock of continuous paper blanks is magnetically recorded and printed.




The former airline ticket printer has an advantage in that the precut ticket blanks can be easily magnetically recorded and printed. These tickets are a sort of high-priced securities, and so there is a need of managing the blanks therefor. However, not only is it difficult to manage such separate ticket blanks, but they are also likely to be missing by wrongdoing or in error. In addition, much difficulty is encountered in finding them, when missing.




The latter airline ticket printer has an advantage in that the continuous ticket blank can conveniently be managed, because whether or not something wrong is occurring can be easily determined by finding the presence of cutouts. However, it is difficult to make magnetic records and prints on a continuous form of ticket blank, and this form of ticket blank costs much time and labor, because it is required for an operator to separate it into individual tickets and hand them to passengers.




SUMMARY OF THE INVENTION




An object of the invention is to provide a valuable form of ticket which, even when printed on a direct thermal printing system, does not erase what is printed.




Another object of the invention is to provide a ticket printer for issuing a valuable form of ticket which, even when printed on a direct thermal printing system, does not erase what is printed.




A further object of the invention is to provide a ticket printer which enables ticket blanks to be easily managed and which is capable of issuing a valuable form of tickets in a separate form.




A still further object of the invention is to provide a ticket printer which is so compact in size that it can be located between desks.




A valuable form of ticket according to the invention enables ticketing data to be magnetically recorded and printed, and includes a base, a heat-sensitive layer applied on one side of the base, a protective layer applied on the heat-sensitive layer and a magnetic recording layer applied on the other side of the base.




Because the protective layer is applied on the heat-sensitive layer, the valuable form of ticket according to the invention can be protected against coming into contact with a solvent, a plasticizer, and so on. Besides, the ticket of the invention can be used in the form of a security, because the color-developing zone is by no means erased, even when formed on a simple direct thermal printing system, and so is high in terms of storage stability.




Because the magnetic recording layer is applied on the side of the base that is opposite to the side thereof on which the heat-sensitive layer is formed and so the heat-sensitive layer is all available in the form of the side to be printed, it is possible to make effective use of the ticket that has a limited area. With the ticket according to the invention wherein the magnetic recording layer is not affected by the heat of a thermal recording element and so the data magnetically recorded there is invariable, it is possible to make sufficient prints and record the magnetic data certainty.




A ticket printer according to the invention comprises a stock holder unit for holding ticket blanks, each including a heat-sensitive layer and a protective layer on one side of a base and a magnetic recording layer on the other side of the base, a thermal printer unit for thermally printing the heat-sensitive layer of each ticket blank fed out of the stock holder unit and a magnetic recorder unit for magnetically recording data on the magnetic recording layer of the ticket blank.




According to this ticket printer, it is possible to issue valuable tickets having high storage stability, because they can be protected against coming into contact with solvents, plasticizers, etc., due to the provision of the protective layer on the heat-sensitive layer, and because their color-developing zones are by no means erased, even when formed by the thermal printer unit that makes use of a simple direct thermal recording system.




Another ticket printer of the invention is designed to print and magnetically record ticketing data on a ticket blank and thereby issue a valuable ticket, and comprises a ticket blank holder for containing a continuous form of medium that is separated along perforations into individual ticket blanks, a pre-feeder unit for feeding the continuous form of medium from the ticket blank holder and cutting and separating the medium into individual ticket blanks, a magnetic recorder unit for magnetically recording ticketing data on a magnetic recording layer of each ticket blank cut by and fed from the pre-feeder unit, and a printer unit for printing ticketing information on the magnetically recorded ticket blank.




This ticket printer makes magnetic recording and printing easy and dispenses with separating tickets after issuance, because, even when a continuous form of medium is used, it is cut through the pre-feeder unit into individual ticket blanks. And these individual ticket blanks are magnetically recorded and printed, and so the valuable ticket blanks can be easily controlled as a continuous form of medium and, besides, can be magnetically recorded and printed individually.




Other features and advantages of the present invention will be apparent from the following description taken in conjunction with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring first to

FIGS. 1-3

, there is shown an airline ticket that is one embodiment of the invention.




As illustrated in FIG.


1


(A), an airline ticket blank, shown generally by


1




a


, comprises a paper base


13


that is provided on its one (back) side with a heat-sensitive layer


14


having on its surface a protective layer


15


formed of water-soluble resin. On the opposite (front) inside of the paper base


13


there is provided a magnetic stripe


11


. This heat-sensitive layer


14


is composed of an irreversible pigment, a developer and a binder.




Thus, the provision of the protective layer


15


on the surface of the heat-sensitive layer


14


can physically prevent a solvent such as alcohol, a plasticizer, and so on from entering the heat-sensitive layer


14


. This in turn makes it possible to prevent a solvent such as alcohol, a plasticizer, and so on from coming into contact with the portion of the heat-sensitive layer


14


that develops color by chemical reactions, thereby breaking up such chemical reactions and so resulting in fade-out.




The irreversible pigment is used as the color-developing dye in the heat-sensitive layer


14


, so that the ticket according to this embodiment can stand up to long-term storage and so is best suited as a reservation ticket.




The magnetic stripe


11


is provided on the side of the paper base


13


that is opposite to the side thereof, on which the heat-sensitive layer


14


is provided, so that the heat-sensitive layer


14


is available all over surface for printing, thus assuring good-enough printing. In addition, the magnetic stripe


11


is unlikely to receive printing heat directly and so the magnetically recorded data thereon is unlikely to change.




Another embodiment of the ticket shown in FIG.


1


(B) follows the construction shown in FIG.


1


(A) with the exception that an additional protective layer


16


is provided on the side of the paper base


13


with the magnetic stripe


11


formed on it. According to this embodiment, it is possible to prevent solvents, plasticizers, etc., from penetrating into the heat-sensitive layer


14


through the paper base


13


, and so it is possible to further improve the storage stability of the ticket.




As illustrated in

FIG. 2

, this airline ticket blank


1




a


is in the form of continuous paper


1


that is provided with folds


19


perforated, as shown at


17


, for its easy separation from equipment. Further, each perforation


17


is cut on both its sides, as shown at


18


, for easier separation of each ticket blank. It is here noted that one ticket blank


1




a


is divided by a fold


19


from another, and provided with additional two perforations


17


′, so that a ticket collector can receive the stub when it is used.




As can be seen from

FIG. 3

which is a storage stability diagram, a conventional heat-sensitive ticket having no protective layer


15


decreases in terms of the residual rate of the color-developing zone to 50% with respect to a solvent, 30% with respect to oils and fats and 10% with respect to a plasticizer, but the heat-sensitive ticket of the invention, shown in FIG.


1


(A), is of good-enough storage stability, because the residual rate of the color-developing zone is nearly invariable, i.e., 100% with respect to a solvent, 100% with respect to oils and fats and 90% with respect to a plasticizer.




The airline ticket printer according to the invention will now be explained with reference to

FIGS. 4

,


5


and


6


.




Referring first to

FIG. 4

, there is perspectively shown an airline ticket printer shown generally as


2


. This ticket printer is built up of a housing


20


, an inlet port


21


through which an unrecorded, unprinted ticket blank is inserted for printing and magnetic recording, an internal stacker or hopper


22


for storing printed, magnetically recorded ticket blanks, and an ejection port


23


for ejecting the printed, magnetically recorded ticket blanks. Reference numeral


24


represents a display (e.g., a liquid-crystal display—LCD) for guidance and other purposes,


25


an indicator (e.g., a light-emitting diode—LED) for providing an indication of what state the ticket printer is in, and so on, and


26


a control panel that is covered and includes keys for various operations.




Referring then to

FIGS. 5 and 6

, the printer


2


includes in its lower portion ticket blank stock holders


3




a


and


3




b


in which the continuous paper


1


shown in

FIG. 2

is set in order and kept in stock. The printer


2


further includes a pre-feeder unit


4


in which the continuous paper


1


fed from the ticket blank stock holders


3




a


and


3




b


is cut and separated into individual tickets blanks


1




a


and the ticket blanks are put in order in the widthwise direction and then in a ready-for-further-feeding state, an MS (magnetic recording) unit


5


for magnetically recording on the magnetic stripe


11


of each separated ticket blank


1




a


ticketing data (for instance, destination, departure and arrival dates and times, flight number, seat number, and so on), and a printer unit


6


for thermally printing on the side


12


, to be printed, of the magnetically recorded ticket blank


1




a


, ticketing data (for instance, destination, departure and arrival dates and times, flight number, seat number, and so on) for issuance.




Also, built in the printer


2


are slide rails


27




a


and


27




b


for pulling out of the housing


20


the ticket blank stock holders


3




a


and


3




b


, pre-feeder unit


4


, MS unit


5


, printer unit


6


, and so on, and a reject unit


28


for keeping some defective tickets


1




a


, if any, in stock.




In the instant embodiment, individual tickets blanks


1




a


are stocked in the form of the continuous paper


1


. This is because the respective ticket blanks


1




a


must have been serially numbered owing to being the originals of securities. The tickets being in the form of continuous paper means that pilferage is by no means feasible, unless the paper is cut; in other words, as long as the tickets are in a continuous form, it can be judged that something wrong such as pilferage has not occurred. In the case where ticket blanks are stocked in a separate state, some considerable time and labor are needed for determining whether or not pilferage has occurred, thus making their control difficult. However, if they are in a continuous form, they can then be easily controlled as securities.




On the other hand, some difficulty is involved in feeding continuous paper directly for magnetic recording, and the continuous paper, if ejected, must be cut manually. For these reasons, the invention is designed such that the continuous paper


1


is cut and separated into individual ticket blanks through the pre-feeder unit


4


, and they are then magnetically recorded through the MS unit


5


and finally printed through the printer unit


6


for issuance.




In addition, the pre-feeder unit


4


is designed such that each ticket blank


1




a


previously cut and separated there is put in a ready-for-further-feeding state and, by an issuance order, is fed to the MS unit


5


, thereby improving the issuance speed.




Furthermore, the printer unit


6


works on a direct printing mode making use of a thermal head, so that printing can be made easily and in a timesaving and laborsaving manner as well.




The ticket printer according to this embodiment is reduced in height and in depth as well by locating the ticket stock holders


3




a


and


3




b


in its lower region and locating the pre-feeder, MS and printer units


4


,


5


and


6


above them. In particular, the ticket printer is made further compact by disposing the pre-feeder unit


4


diagonally to extend the ticket blank feed passage from the lower portion to the back side thereof and then from the back side to the front side thereof.




In order to print and magnetically record data on a manually inserted ticket blank, the ticket blank is inserted into the MS unit


5


through the inlet port


21


for magnetic recording and then printed through the printer unit


6


for issuance. The provision of the internal stacker


22


enables a large quantity of tickets for party travelers, for instance, to be stacked up and issued.




Each part of such an airline ticket printer will now be explained at great length. Reference will first be made to

FIGS. 7

,


8


,


9


,


10


A and


10


B.




As can be seen from

FIG. 7

, there are provided ticket suction ports


40




a


and


40




b


through which the continuous paper


1


is sucked from the ticket blank stock holders


3




a


and


3




b


, feed rollers


41




a


and


41




b


for paper feeding and pinch rollers


41




c


and


41




d


for feeding the paper while it is held between the feed rollers


41




a


and


41




b


. Also, there are provided ejection rollers


42




a


and


42




b


for paper feeding and pinch rollers


44




a


and


44




b


for feeding the paper while it is held between the rollers


42




a


and


42




b


. Additionally, there are provided pulse motors PM


1


and PM


2


for driving the rollers


41




a


,


42




a


and


41




b


,


42




b


and timing belts


43




a


and


43




b


for rotating the rollers


41




a


,


42




a


and


41




b


,


42




b


by the rotational forces of the pulse motors PM


1


and PM


2


.




Magnets MG


1


and MG


2


are provided for engaging or disengaging the pinch rollers


44




a


and


44




b


with or from the rollers


42




a


and


42




b


, and sensors S


1


and S


2


are located for detecting that a cut medium passes by and is present or absent. Reference numeral


45


represents a cam for driving a link


46


linearly, PM


3


a pulse motor for rotating the cam


45


,


46


a link designed to move linearly by the rotation of the cam


45


, and


47




a


and


47




b


burst cutters that are driven by the link


46


for burst-cutting the perforation


17


in the continuous paper


1


. S


3


represents a sensor for sensing the location of the link


46


, thereby detecting that the cutters


47




a


and


47




b


are at their positions available for cutting, and S


4


denotes another sensor for sensing the location of the link


46


, thereby detecting that the cutters


47




a


and


47




b


are at their retracted positions.




As can be seen from

FIGS. 8 and 9

, the feed rollers


41




a


and


42




a


are attached to a unit frame


48


of the pre-feeder unit


4


. This feed roller


41




a


is provided with a gear


410


that meshes with the timing belt


43




a


driven by a driving gear


411


of the pulse motor PM


1


. Similarly, the feed roller


42




a


is provided with a gear


420


that meshes with the timing belt


43




a


, a gear


421


integral with the gear


420


, a gear


422


and auxiliary gears


423


,


424


.




As illustrated in FIG.


10


(A), the gears


420


and


421


of the feed roller


42




a


are provided therethrough with a one-way clutch


421




a


that works only in the direction shown at B in this figure, and the gear


422


is provided therethrough with a one-way clutch


422




a


as well, which works only in the direction shown at B in this figure. Then, the auxiliary gear


423


meshes with the gear


421


, the auxiliary gear


424


meshes with the auxiliary gear


423


, and the gear


422


meshes with the auxiliary gear


424


.




As can be seen from FIG.


10


(A), as the timing belt


43




a


is driven in the direction B, the rotations of the gears


420


and


421


are transmitted to the shaft of the feed roller


42




a


by way of the one-way clutch


421




a


, so that the feed roller


42




a


can rotate in the direction B or forwardly. At this time, the gear


422


is rotated in the direction A or backwardly by the gear


421


through the auxiliary gears


423


and


424


, but it remains idle by the operation of the one-way clutch


422




a.






Then, as the timing belt


43




a


is driven in the direction A in FIG.


10


(A), the gears


420


and


421


rotate, but they remain idle by the operation of the one-way clutch


421




a


. This in turn causes the gear


422


to rotate by the gear


421


by way of the auxiliary gears


423


and


424


in the direction B or forwardly in this figure, so that its rotation can be transmitted to the shaft of the feed roller


42




a


by the one-way clutch


422




a


, thereby rotating the feed roller


42




a


in the direction B or forwardly in this figure.




Thus, the feed roller


42




a


can be rotated in the direction B or forwardly, irrespective of whether the timing belt


43




a


is fed in the direction A (forwardly) or B (backwardly), enabling the medium to be fed forwardly.




As illustrated in FIG.


10


(B), a right-hand frame


48


′ is provided with a biasing spring


49


that serves to engage each cut ticket blank


1




a


with a left-hand frame


48


, so that it can be put in order in the widthwise direction.




While the arrangement shown in

FIGS. 8-10

has been described chiefly with reference to the suction port


40




a


that corresponds to the ticket blank holder


3




a


shown in

FIG. 7

, it is understood that this is true of the suction port


40




b


that corresponds to the ticket blank holder


3




b.






How the pre-feeder unit


4


works will now be explained with reference to

FIGS. 11

,


12


A,


12


B,


13


A and


13


B.




In their initial state shown in FIG.


12


(A), the cutters


47




a


and


47




b


are at their ready-to-cut positions, and so block up the feed passage. In this state, the operator operates an associated lever, not shown, to retract the pinch roller


41




c


, and then inserts the continuous paper


1


into the suction port


40




a


until it abuts against the back of the cutter


47




a


. Thereafter, the operator operates the lever to close up the pinch roller


41




c


, and then inserts the leading end of the continuous paper


1


between the feed roller


41




a


and the pinch roller


41




c


for setting the continuous medium in place.




Then, the magnet MG


1


is first driven to close up the retracted pinch roller


44




a


so as to retract the cutter


47




a


, as shown in FIG.


12


(B). Subsequently, the pulse motor PM


3


for the cutter is rotated counterclockwise (or in the CCW direction) to move the link


46


by the cam


45


in the right-handed direction in this figure, thereby retracting the cutter


47




a


. The rotation of this pulse motor PM


3


is put off, when the output of the sensor S


4


is so low that it reaches its retracted position, as shown in FIG.


11


.




With the pulse motor PM


1


for paper feed rotated counterclockwise (or in the forward direction), the feed rollers


41


and


42




a


are then rotated in the forward direction by the timing belt


43




a


for paper feed. The pulse motor PM


1


stops upon the perforation


17


of the medium


1


reaching the location of the cutter


47




a


. This is because the output of the sensor S


1


decreases upon detecting that the leading end of the medium


1


passes by. In this state, the perforation


17


in the medium (continuous paper)


1


is positioned at the location of the cutter


47




a.






Then, the PM


1


for paper feeding is rotated


2


to


5


steps clockwise (or in the CW direction), as shown in FIG.


13


(A). This in turn causes a reversal of the feed roller


41




a


and a forward rotation of the feed roller


42




a


by the operations of the above-mentioned one-way clutches


421


and


422




a


shown in

FIG. 10

, thereby pulling the medium


1


by both the feed rollers


41




a


and


42




a


to impart tension to the medium


1


, thereby making it easy to cut the medium


1


.




With no tension imparted to the medium


1


, the continuous medium


1


may become loose at the location of the cutter due to a difference in the feed speed between both the feed rollers


41




a


and


42




a


that is caused by their outer diameter accuracy, making the proper cutting of the medium


1


unlikely. In the instant embodiment, however, tension can be applied by the feed rollers


41




a


and


42




a


to the medium. In other words, the feed mechanism itself has the ability to impart tension to the medium, and so can be simplified in structure.




As shown in FIG.


13


(B), the pulse motor PM


3


for the cutter is further rotated counterclockwise to move the link


46


by the cam


45


in the left-handed direction in this figure, so that the cutter


47




a


can beat the perforation


17


of the medium


1


for burst-cutting.




The medium


1


can then be cut easily and surely, because tension is imparted to the medium


1


, as shown in FIG.


13


(A), and because the perforation


17


in the medium


1


is cut on both its sides, as shown at


18


.




After the cutting of the medium is completed, the pulse motor PM


1


is rotated


40


steps clockwise (or in the CW direction), as shown FIG.


11


. This in turn causes a reversal of the feed roller


41




a


and a forward rotation of the feed roller


42




a


by the operations of the above-mentioned one-way clutches


421




a


and


422




a


shown in

FIG. 10

, thus separating the cut medium


1




a


from the continuous medium


1


and putting it in a ready-for-further-feeding state on the ejection port side.




After that, as the magnet MG


1


is put off, as shown in

FIG. 11

, the pinch roller


44




a


is retracted to enable each cut medium


1




a


to be widthwise engaged with the left-hand frame


48


by the biasing spring


49


attached to the right-handed side frame


48


′, shown in FIG.


10


(B). In this manner, the pre-feeding of each ticket blank is completed.




Upon receipt of an issuance command, the sequences from FIG.


12


(B) occur, and the cut medium


1




a


that is standing ready for further feeding is fed to the magnetic recording unit


5


, while the continuous medium


1


is fed and cut and then allowed to stand ready for further feeding.




Because the set continuous paper


1


is precut into individual ticket blanks


1




a


ready for further feeding, each ticket blank


1




a


can be fed to the magnetic recorder unit


5


just upon receipt of issuance instructions, thereby improving issuance speed.




While the operations of the parts located on the suction port (


40




a


) side corresponding to the ticket blank holder


3




a


have been described with reference to

FIGS. 12A

,


12


B,


13


A and


13


B, it is understood that those on the suction port (


40




b


) side corresponding to the ticket blank holder


3




b


operate similarly. In this case, the cutter-driving PM


3


, cam


45


and link


46


are commonly used.




The magnetic recording unit


5


will now be explained with reference to

FIGS. 14

,


15


,


16


A and


16


B.




As shown in

FIG. 14

, the MS (magnetic recording) unit


5


includes a manually-inserting portion


5




b


for receiving a manually inserted ticket blank, an MS read-write unit


5




a


for magnetically recording data on the magnetic stripe


11


of the ticket blank and a portion


5




c


in which the manually inserted ticket blank stands ready for further feeding. As shown in

FIGS. 14 and 15

, an upper feed belt


52


is provided all over the hand-inserting portion


5




c


, the MS read-write portion


5




a


and the portion


5




c.






The MS read-write unit


5




a


is provided with a lower feed belt


53


for feeding the ticket blank


1




a


while it is held between the upper and lower feed belts


52


and


53


, a write head


50


for magnetically recording data on the magnetic stripe


11


of the ticket blank


1




a


and a read heat


51


for read-after-write check.




Further, there are provided a guide roller


50




a


opposite to the write head


50


, a guide roller


51




a


opposite to the read head


51


, a gate


54


for guiding the magnetically recorded ticket


1




a


to the printer unit


6


or the hand-inserting portion


5




b


, and a discharge roller


55


for ejecting the ticket


1




a


into the printer unit


6


.




The manually-inserting portion


5




b


includes a shutter


56


located on an inserting port


21


and a magnet MG


3


that opens the shutter


56


in association with hand insertion, thereby switching the gate


54


over to the hand-inserting portion


4




b.






The standby portion


5




c


includes a roller


57


opposite to the upper feed belt


52


and a magnet MG


4


for moving and engaging the roller


57


toward and with the upper feed belt


52


.




As shown in

FIG. 16A

, the MS read-write unit


5




a


includes a biasing spring


58


attached to a right-hand frame


59


′, which serves to bias the ticket blank


1




a


at the write and read heads


50


and


51


against a left-hand frame (guide).




Explaining this operation, the ticket blank


1




a


fed from the pre-feeder unit


4


is supplied, while it is sandwiched between the upper and lower feed belts


52


and


53


in

FIG. 16B

, to the write head


50


where data are magnetically recorded on the magnetic stripe


11


of the ticket blank


1




a


. Then, it is further fed to the read head


51


where the data are read, and ejected into the printer unit through the ejection roller


55


by way of the gate


54


.




In this case, it is assured that the data can be written onto the magnetic stripe by the write head


50


and read therefrom by the read head


51


, because the ticket blank


51




a


is carried while it is biased by the biasing spring


58


against the left-hand guide


59


on the side at which there are the heads


50


and


51


. Also, since the ticket blank is fed by the feed belts


52


and


53


without undergoing any speed change, it is assured that the data can be written onto the magnetic stripe


11


by the head


50


and read therefrom by the head


51


.




In the case of the manually inserted ticket blank, on the other hand, the shutter


56


is opened by the magnet MG


3


and the gate


54


is actuated to connect the hand-inserting portion


5




b


with the MS read-write portion


5




a


. Then, the ticket blank


1




a


is fed by the upper feed belt


52


through the inserting port


21


and the read-write portion


5




a


to the standby portion


5




c


where it stands ready for further feeding as shown in FIG.


14


.




Upon receiving an issuance order, the magnet MG


4


of the standby portion Sc is driven to feed the ticket blank


1




a


to the MS read-write unit


5




a


while the roller


57


is engaged with the upper belt


52


. Through the MS read-write unit


5




a


, the ticket blank


1




a


is fed while it is sandwiched between the lower belts


52


and


53


, in the course of which the data are magnetically recorded on the magnetic stripe


11


of the ticket blank


1




a


and read therefrom by the read head


51


. Then, the ticket blank


1




a


is ejected by the ejection roller


55


into the printer unit


6


by way of the gate


54


.




The printer unit


6


will now be explained with reference to the FIG.


17


.




In

FIG. 17

, reference numeral


60


represents a line thermal head for the thermal printing of the heat-sensitive ticket blank including the protective layer, shown in

FIG. 1

,


61


a platen that is located in opposition to the thermal head


60


,


62


a lever for keeping the space between the thermal head


60


and the platen


61


constant, and MG


5


a magnet for driving the lever


62


.




Reference numeral


63


is a feed belt for feeding the printed ticket


1




a


toward the ejection port


23


,


64


a feed belt for carrying the printed ticket


1




a


to the hopper (internal stacker)


22


,


65


a gate for guiding the printed ticket


1




a


to the hopper


22


or the discharge port


23


, and MG


6


a magnet for driving the gate


65


for switching-over.




Reference numeral


66


denotes a gate for guiding the printed ticket


1




a


to the reject box


28


or the ejection portion


23


, MG


7


a magnet for driving the gate


66


for switching-over, and PM


4


a pulse motor for driving the feed belt


64


, etc.




Explaining this operation, the ticket blank


1




a


fed from the MS unit


5


strikes on the thermal head


60


where its leading end is properly positioned and whence it is fed to the platen


61


, in the course of which it is linearly printed.




In order to eject the ticket blank


1




a


into the ejection port


23


, the magnet MG


6


is put on to locate the gate


65


at a position shown by a dotted line in FIG.


17


. The gate


66


is then located at a position shown by a solid line in this figure, so that the ticket


1




a


can be ejected into the ejection port


23


. For ejection into the hopper


22


, on the other hand, the magnet MG


6


is put off to locate the gate


65


at the position shown by a solid line in

FIG. 17

, thereby guiding the ticket


1




a


into the hopper


22


.




If the ticket is rejected due to some error in magnetic recording, etc., the magnet MG


7


is then put on to locate the gate


66


at the position shown by a dotted line in

FIG. 17

, thereby guiding that ticket


1




a


into the reject box


28


.




In what follows, the printer unit


5


will be explained more specifically with reference to

FIGS. 18

,


19


A,


19


B,


20


A and


20


B.




As shown in

FIGS. 18

,


19


A and


19


B, the thermal head


60


is made up of a thermal line head including an array of heat elements corresponding to one line, which are arranged in the axial direction of the platen


61


, and is attached to a bracket


600


by means of a fixing screw


600


-


1


. At both ends of the bracket


600


there are positioning shafts


601


and


602


, and on the bracket


600


there is a pin


603


and a sheet spring


604


.




On the other hand, the printer unit


6


is provided with a swing lever


606


that swings around its fulcrum


607


. This swing lever


606


is provided with a hanger


608


, and biased counterclockwise (see

FIG. 18

) by a spring


605


. This hanger


608


receives both the pin


603


and the sheet spring


604


at its center, as shown in FIGS.


19


(A) and (B), and is provided with a positioning groove


609


that comes into contact with the bracket


600


. The printer unit


6


is also provided in its frame with a positioning groove


610


that engages with the positioning shaft


602


of the bracket


600


.




Further, an axis


61




a


of the platen


61


opposite to the thermal head


60


is provided with a lever


62


that swings around an axis x to force up (the printing line portion of) the thermal head


60


against the biasing force of the spring


605


. This lever


62


is limited by a stopper


620


in terms of the position at which it swings clockwise in

FIG. 18

, biased clockwise by a spring


621


, and driven counterclockwise by the magnet MG


5


through a lever X.




In such an arrangement, the lever


62


abuts against the stopper


620


by the spring


621


, so that it can be limited in terms of the position at which it swings, thereby spacing the thermal head


60


about 0.1-0.2-mm away from the platen


61


.




At this time, the tickets


1




a


ejected through the ejection rollers


55


of the MS unit


5


abut against the diagonally positioned thermal head


60


, so that their leading ends can be in alignment.




Subsequent driving of the magnet MG


5


causes the lever


62


to swing clockwise around the axis X through a shaft X of the lever X that swings around an axis Y, thereby releasing the upward displacement of the thermal head


60


. This in turn causes the thermal head


60


to be engaged with the platen


61


following the biasing force of the spring


605


, enabling the platen


61


to be fed and so making thermal recording by the thermal line head


60


possible.




At this time, the location of the thermal head


60


with respect to the platen


61


is assured by engaging the positioning shaft


602


of the bracket


600


—to which the thermal head


60


is fixed—within the positioning groove


610


in the frame.




The horizontal location of the thermal head


60


, on the other hand, is assured by engaging the pin


603


extending from the center of the bracket


600


within the positioning groove


609


in the center of the hanger


608


and biasing the opposite side thereof by means of the sheet spring


604


, as shown in

FIG. 19

, thereby making the positioning of the thermal head


60


easier.




Further, the thermal head


60


is designed to be rotatable around the pin


603


fitted within the positioning groove


609


in the hanger


608


, as shown in FIG.


19


(B), so that it can turn following the platen


61


, keeping printing pressure constant. This in turn enables printing density to be kept constant in dependence on a paper thickness variation, eccentricity of the platen


61


, and so on.




The attachment or detachment of the bracket


600


that supports the thermal head


60


in place will now be explained more specifically with reference to FIG.


20


. For detachment of the thermal head


60


from the swing lever


606


of the bracket


600


that supports it in place, the spring


605


is removed to swing the swing lever


606


upward in FIG.


18


. Then, the bracket


600


that fixes the thermal head


60


in place is disengaged from the platen


61


and from within the positioning groove


610


. Subsequently, a push is given by a finger to the sheet spring


604


of the bracket


600


, as shown in FIG.


20


(A) to deform the sheet spring


604


, thereby detaching the pawl of the sheet spring


604


from the hanger


608


. Finally, the bracket


600


with the thermal head


60


fixed to it is turned downward, whereby the bracket


600


with the thermal head


60


fixed to it can be disengaged from the hanger


608


.




The attachment of the swing lever


606


to the bracket


600


is achieved in the opposite manner as mentioned above, i.e., by fitting the pin


603


extending from the bracket


600


into the positioning groove


610


in the hanger


608


and then forcing therein the side of the bracket


600


on which the sheet spring


604


is attached.




After that, while the spring


605


is attached to the swing lever


606


, the positioning shaft


602


of the bracket


600


is fitted in the positioning groove


610


in the frame, so that the thermal head


60


and platen


61


can be regulated in terms of their positions.




Thus, the attachment or detachment of the thermal head


60


to or from the associated bracket


600


is easily achievable by providing the positioning groove


609


in the hanger


608


and engaging or disengaging the pin


603


and sheet spring


604


of the bracket


600


within or from that groove


609


.




Further, the printing line of the thermal head


60


and the platen


61


can be regulated in terms of their positions by engaging the positioning shaft


602


of the bracket


600


within the positioning groove


610


in the frame.




Still further, the line thermal head


60


is designed to be rotatable around the positioning groove


610


in the hanger


608


in the line direction, thus enabling printing pressure and density to be made uniform in the horizontal direction.




In addition, the printer unit can be achieved simply and inexpensively, because the mechanism for attachment or detachment of the thermal head


60


is made integral with the mechanism for making density uniform.




How to ticket will be explained chiefly with reference to

FIGS. 6 and 7

.




In the pre-feeder unit


4


, the continuous paper


1


held in the ticket blank holders


3




a


and


3




b


is first cut, biased and put in a ready-for-further-feeding state.




Upon receiving a ticketing command, the pre-feeder unit


4


is actuated to feed each cut ticket blank


1




a


to the MS unit


5


where it is biased and data is magnetically recorded on its magnetic stripe


11


and then it is fed to the printer unit


6


.




In the printer unit


6


, the data is thermally recorded by the thermal head


60


on the ticket blanks


1




a


with their leading ends in order, and they are then ejected into the ejection port


23


or the hopper


22


.




Following the feed of the cut ticket blanks


1




a


by the pre-feeder unit


4


, the next continuous paper


1


may be fed, positioned and separated by cutting into individual ticket blanks


1




a


for making ready-to-feed. In other words, the next cut ticket blanks


1




a


are made for ready-for-further-feeding while the preceding cut ticket blanks


1




a


are magnetically recorded and thermally printed, thus improving the issuance speed of tickets.




The ticket blank holders


3




a


and


3




b


hold airline ticket blanks in the form of continuous paper, and so the management of the securities can not only be easily achieved, but something wrong can immediately be found as well. In addition, the continuous paper is separated by cutting into individual ticket blanks


1




a


, and so not only is it assured that they are magnetically recorded and thermally printed, but there is also no need of separating the continuous paper into individual ticket blanks after ejection.




While the instant embodiment has been described with reference to airline tickets, it is understood that the invention is applicable to other securities or tickets such as passenger or reservation tickets.




Next, another embodiment of the pre-feeder unit


4


will be explained with reference to

FIGS. 21

,


22


A and


22


B.




As shown in FIGS.


21


(


a


) and


21


(


b


) that are the perspective and side views of such an embodiment, a gear


425


is coaxially fixed to a shaft of a feed roller


42




a


, which in turn meshes with a gear


423


. The gears


425


and


423


are respectively in mesh with gears


421


and


422


that are mounted on their driving shaft through one-way clutches


421




a


and


422




a


, respectively. The driving shaft is provided at its one end with a toothed pulley


420


. It is noted that pulleys


410


,


411


and


420


are connected with one another by a belt


43




a.






The one-way clutches


421




a


and


422




a


are mounted such that the gears


421


and


422


are each rotated in the opposite direction. To put it another way, when the pulley


420


is rotated in the direction shown by an arrow A, the one-way clutch


422




a


disengages the gear


422


to keep it idle, while the one-way clutch


421




a


is actuated to rotate the gear


421


and thereby rotate the gear


425


through the gear


423


, so that the feed rollers


420


can be rotated in the feed direction of the continuous paper


1


.




When the pulley


420


is rotated in the direction shown by an arrow B, on the other hand, the one-way clutch


421




a


disengages the gear


421


to keep it idle, while the one-way clutch


422




a


is actuated to rotate the gear


422


and then the gear


425


, so that the feed roller


42




a


can again be rotated in the feed direction of the continuous paper


1


.




According to the pre-feeder unit


4


of the construction mentioned above, the continuous paper


1


fed from the ticket blank holder


3




a


is fed in the feed direction by the forward rotation, i.e., rotation shown by the arrow A, of the motor PM


1


, because the pulleys


410


and


420


are then rotated in the direction shown by the arrow B to rotate the feed rollers


41




a


and


42




a


in the same direction.




With the continuous paper


1


fed to a predetermined position, the motor PM


1


stops, and then rotates in the opposite direction, i.e., the direction shown by the arrow B in FIG.


21


. Thereupon, the pulleys


410


and


420


are rotated in the direction shown by the arrow B and, as illustrated in FIG.


22


(B), this then causes the rotation of the feed roller


41




a


in the opposite direction and the rotation of the feed roller


42




a


in the forward direction.




Consequently, the continuous paper


1


is pulled and tensioned regardless of the presence or absence of looseness, because the feed rollers


41




a


and


42




a


are each rotated in the opposite direction.




Then, the continuous paper


1


is cut along the perforations


17


into individual ticket blanks


1




a


by the cutter


47




a.






The tickets


1




a


are then carried by driving the feed rollers


41




a


and


42




a


to the MS read-write unit


5


.




In the ensuing description, a further embodiment of the pre-feeder unit


4


will now be explained with reference to.

FIGS. 23

,


24


A and


24


B.




The construction shown in

FIG. 23

follows that of the embodiment illustrated with reference to

FIG. 21

, with the exception that when the motor PM


1


is rotated in the opposite direction (the direction shown by an arrow B), the feed roller


41




c


is caused to stop rather than rotate in the opposite direction. According to the embodiment shown in

FIG. 21

, when the feed roller


41




c


is rotated in the opposite direction, the continuous paper


1


is cut, but the rest of the continuous paper


1


may be fed back in that moment. The instant embodiment is provided to avoid this.




More specifically, the axis of the feed roller


41




c


is provided at its one end with a toothed pulley


410


through a one-way clutch


410




a


, as illustrated in FIG.


23


. Consequently, it is when the motor PM


1


is driven in the forward direction (or in the direction shown by an arrow A) that the one-way clutch


410




a


is so actuated that the feed roller


41




c


can rotate in the forward direction (or in the direction A). In contrast, it is when the motor PM


1


is driven in the opposite direction (or in the direction shown by an arrow B) that the one-way clutch


410




a


disengages the pulley


410


, so that it can be kept idle, thereby keeping the feed roller


41




c


from rotation.




When the motor PM


1


is driven in the opposite direction (or in the direction B), the feed roller


42




a


is rotated in the feed direction, but the feed roller


41




a


is not rotated by the rotational force of the pulley


410


. Consequently, a sag in the continuous paper


1


is temporarily pulled, and so tension is imparted to the continuous paper


1


. Subsequently, the continuous paper is fed by the feed roller


42




a


under that tension, so that, as shown in the time chart presented in the form of FIG.


24


(B), the continuous paper


1


can be cut along the perforation


17


by the cutter


47




a


at a timing at which that sag is pulled by the feed roller


41




a


just after the backward driving of the motor PM


1


.




The feed roller


41




a


is then not rotated, and so the feeding-back of the rest of the continuous paper


1


is avoided, thus enabling the distance to the next cutting position to be reduced. The time reduction achieved per ticket is slight, but the total ticketing time can be much reduced in the case of issuing a large number of tickets sequentially.




How to regulate the position of the MS unit


5


at which data recording is initiated is described below.




As shown in FIG.


25


(A), the main part of the MS unit


5


is built up of a sensor SS for sensing the leading end of each ticket blank


1




a


, a write head


50


disposed in the rear of the sensor SS by a predetermined distance LI, a read head


51


located in rear of the write head


50


and a sensor ES located in rear of the read head


51


for sensing the trailing end of each ticket blank

a.






With each ticket blank


1




a


—that has been fed from the ticket blank holder


2




a


and is now ready to leave in the pre-feeder unit


4


—fed out of the pre-feeder unit


4


as per ticketing instructions, it is fed by the belt mechanism


52


to the passage for the MS unit


5


. When the ticket blank


1




a


is carried to a given position through a predetermined distance S after its leading end has been sensed by the sensor SS, as shown in FIG.


25


(B), boarding reservation data (departure date and time, flight number, passenger's name, and so on) sent out of external equipment is magnetically recorded by the write head


50


on the magnetic stripe


11


of the ticket blank


1




a.






The data recorded on the magnetic stripe


11


of the ticket blank


1




a


is reproduced by the read head


51


for checkup. If there is no error, the ticket blank


1




a


is fed to the printer unit


6


where the data is printed and then it is sent out of the issuance port. Then, when the printing is ended, the completion of ticketing is notified. This enables the succeeding ticket


1




a


to be ready to leave the pre-feeder unit


4


.




It is to be noted that the position of a predetermined distance S taken by the ticket blank


1




a


after its leading end has been detected lies at the position of a distance L


2


from the leading end of the magnetic stripe


11


to the write head


50


(i.e., L


2


=S−L


1


), and this distance L


2


must lie within a certain tolerable range with respect to a predetermined size.




In other words, the writing of the data onto the magnetic stripe by the write head


50


is initiated after the lapse of a time period t from the detection of the leading end of the ticket


1




a


by the sensor SS to the time at which the leading end of the ticket blank


1




a


would reach the position of the distance S.




When the distance L


2


is too short, reading is unlikely to occur because some difficulty is involved in the synchronization of the read signals, whereas when it is too long, some data are unlikely to be recorded because the recording zone of the magnetic stripe


11


becomes narrow. For assuring stable reading and recording region, there are thus the ISO and JIS standards (e.g., 7.44 Mmm±1.0 mm).




However, the given distance S depends on the accuracy of the spacing between the sensor SS and the write head


50


and, besides, there is an error in the accuracy of mechanical feeding by the belt mechanism


52


, which in turn gives rise to an error in the distance L


2


. For this reason, after data is actually recorded on the ticket blank


1




a


, the recording initiation position from the leading end of the magnetic strip of the ticket


1




a


is measured to regulate the quantity of the error alone. So far, this regulation has been achieved by the following procedures.




The first procedure, as already mentioned above, involves recording data on the magnetic stripe


11


of the ticket


1




a


and visualizing the magnetic pattern with the use of a developer to measure the distance L


2


to the write start position on the ticket blank


1




a


under a scaled magnifier. In the process of this development, the magnetic stripe


11


is treated with a developer composed of a mixture of a volatile liquid with magnetic powders. Then, the volatile component volatilizes, leaving the magnetic powders on the data part.




When the results of this measurement teach that the error deviates from the prescribed value, the relative distance between the sensor SS and the write head


50


is adjusted by changing the position at which the sensor SS is mounted, again, followed by magnetic recording and development to measure the recording start location. In other words, the first procedure is a method of trial and error.




The first procedure may be achieved by a mere displacement of the position of the sensor SS but, in this case, it is sometimes required to provide some mechanism for the fine adjustment of the location of the sensor SS.




A second procedure that is similar to the first procedure in that data is recorded on the magnetic stripe


11


of the ticket blank


1




a


and then developed. The distance of movement of the ticket blank


1




a


is from the time when the sensor SS detects the leading end of the ticket


1




a


to the recording start time.




To be more specific, an encoder, (not illustrated), is provided on the driving pulley of the belt mechanism


52


for feeding the ticket


1




a


. Then, the distance of movement of the ticket


1




a


is calculated. It is when the sensor SS reaches a given calculated value t after detecting the leading end of the ticket blank


1




a


that the write head


50


starts to record.




This is followed by development and measurement. The recording start position, when there is an error, is regulated by increasing or decreasing this calculated (or set) value.




It is noted that the second procedure may also be achieved by using a stepping motor for driving the driving pulley in place of the encoder, but there is a need of increasing or decreasing the stepping number of the motor.




A problem with the above-mentioned conventional procedures, however, is that they are all time and labor consuming, because of involving the steps of development, measurement and regulation after the recording of data on the magnetic stripe of a ticket blank.




According to the instant embodiment, this problem is solved by making it possible to automatically regulate the recording start position on a ticket blank by the mere insertion of the ticket blank.





FIG. 26

is a block diagram presented for achieving this. In

FIG. 26

, a control panel


26


is similar to that shown in

FIGS. 4 and 5

stores the value of the frequency F of the clock signals set out of the clock generator

and a recording frequency F of data “0” generated from a data generator block

Further, the CPU, when the correction-mode indicating button

is pushed down, is actuated to detect an error in the recording start position by a series of controls shown in

FIG. 27

, and thereby executes the automatic correction of the recording start position.

FIG. 27

represents the functions of the CPU in the main control block


70


of

FIG. 26

in block form, and the functions of the main control block


70


will now be explained with reference thereto.




In

FIG. 27

, a cycle counter block


70


-


1


is constructed from a peak detector sub-block


80


, a cycle detector sub-block


81


and a counter


82


, and a calculator block


70


-


2


is built up of a feed speed calculator sub-block


83


, a recording density calculator sub-block


84


, a recording start position calculator sub-block


85


and a correction time calculator sub-block


88


. In what follows, the function of each block will be explained.




A feed time setting block


92


is made up of a memory, and initially set with a theoretical write start time t until the leading end of a ticket blank


1




a


is detected to start recording data, wherein t=SN, where S is the recording start position (to be described later) and is the feed speed. However, this preset t, when the correction time Δt to be described later is found, is replaced by a correction time t′(=t+Δt).




A block


71


(see

FIG. 26

) for generating data at the correction-mode time stores data “0” and “1” and, when the correction mode is indicated by pushing down the correction-mode indicating button


260


, is actuated to generate the data “0” that is recorded from the time the sensor SS detects the leading end of a ticket blank


1




a


to the the data-recording start time (i.e., the feeding time t of the ticket blank


1




a


) and the data “1” that is recorded from the data-recording start time. FIG.


29


(


a


) represents the timings of the sensor-detected signals and the recording signals. It is noted that the magnetic inversion cycles of the data “0” and “1” lie at a ratio of 2 to 1, and that the magnetic inversion cycle of the data “0” or the recording frequency is f.




In the cycle counter block


70


-


1


, the peak of the output signal corresponding to the magnetic inversion of the data read on the read head


51


is detected by the peak detector sub-block


80


from the leading end of the ticket blank


1




a


having the data “0” and “1” recorded thereon, as shown in FIG.


29


(


c


)(


1


), and the number of all cycles N until the changing of the data from “0” to “1” is detected is counted by the counter


82


, as shown in FIGS.


29


(


c


)(


2


) and


29


(


c


)(


3


).




In other words, the counter


82


counts the changing cycle of the data from “0” to “1” in terms of the number of all cycles detected by the cycle detector sub-block


81


. FIG.


29


(


c


)(


4


) represents a signal detecting that the peak signal cycle is reduced because of the changing of the data from “0” to “1”.




In the feed speed calculator sub-block


83


, an actual feed speed V given by LF/M is found, wherein F is the clock frequency read from RAM


77


, M is all the clock signals counted by the clock counter and L is the length of the ticket blank


1




a.






In the recording density calculator sub-block


84


, a recording density given by f/v is found, wherein f is the recording frequency read from RAM


77


and V is the actual feed speed.




The recording start position calculator block


85


is built up of a distance calculator


86


and a comparator


87


. In the distance calculator


86


, a distance S from the sensor SS to the recording start position given by NV/F is found, wherein N is the total cycle number N counted by the cycle calculator block


70


-


1


and f/V is the recording density calculated by the recording density calculator sub-block


84


. In the comparator


87


, the absolute value ΔS of a difference between the measured distance S and a preset distance S


0


to the recording start position is found and compared with a prescribed value S


L


for an allowable tolerance limit set in an allowable-value setting block


91


to determine of ΔS>S


L


or ΔS≦S


L


. When ΔS>S


l


, the main control block


71


is notified of the “need” for correcting the recording start position, and when Δ≦S


L


, the main control block


71


is notified of the “no need” for correcting the recording start position.




The correction time calculator block


88


includes a correction data calculator


89


and a correction feed time calculator


90


. The correction data calculator


89


, when there is the “need” for correcting the recording start position, calculates the correction time Δt given by ΔS/V, where ΔS is the difference found by the comparator


87


and V is the feed speed, according to instructions from the main control block


71


. With the correction time Δt found, the correction time feed time calculator block


90


is actuated to correct the feed (write start) time t that is initially set in the feed time setting block


92


with the correction time Δt. That is, the correction feed time t′=t±Δt is calculated.




In the ensuing description, the operation of the instant embodiment will be explained with reference to the flow chart of FIG.


28


.




(1) First, the power source of the apparatus is turned on and the correction-mode indicating button


260


is pressed down to set the correction mode.




Then, a ticket blank


1




a


(of accurate length L) for testing purposes is inserted through the inserting port


21


, shown in

FIGS. 4 and 5

, and whence it is fed through the MS unit


5


to the unit


5




c


where the manually inserted ticket blank stands for further feeding, as is the case with the manually inserted ticket blank. From this unit


5




c


, it is fed to the MS read-write unit


5




a


. When the leading end of the ticket blank


1




a


is here detected by the sensor SS, the clock counter


76


is triggered to count the number of all clock signals (having frequency F) generated until the sensor SS detects the trailing end of the ticket blank


1




a


. Then, the accurate actual feed speed V is found in the feed speed calculator block


83


from the length L of the ticket blank


1




a


and the total clock signals M; in other words, it is calculated from V=L×F/M.




(2) Further, the recording density f/V is found in the recording density calculator block


84


by dividing the recording frequency f read from RAM


77


by the feed speed V.




(3) From the time the sensor SS detects the leading end of the ticket blank


1




a


, on the other hand, recording is made with the use of the feed (write start) time t initially set in the feed time setting block


92


. Before the recording start time t, the main control block


70


continuously output the data “0” from a data generation unit


71


that works at the correction value-determining time for recording them on the magnetic stripe


11


of the ticket blank


1




a


by the write head


50


. After the recording start time t, the data is changed to “1” for recording.




(4) Now, the data “0” is read by the read head


51


from the leading end of the fed ticket blank


1




a


, and the counter


82


counts the total cycle number N until the cycle detector subblock


81


detects that the data is changed from “0” to “1”.




(5) The counted total cycle number N and the recording density f/V calculated at Step (2) are fed to the recording start position calculator block


85


, where the distance S to the recording start position is found by the distance calculator


86


; in other words, the distance is calculated from S=N×V/f.




(6) In the comparator


87


, the absolute value ΔS (=S−S


0


) of the difference between the distance S and the preset distance S


0


to the recording start position is found and compared with the prescribed value S


L


in the allowable value setting block


91


to provide determination of ΔS>S


L


or ΔS≦S


L


, notifying the main control block


71


of the “need” or “no need” of correcting the distance S. When there is no need, no correction occurs. Hence, subsequent recording of the ticket blank


1


A is done with the use of the write start time t that is initially set in the feed time setting unit


12


.




(7) When there is the “need” of correcting the distance S, ΔS is divided by the feed speed V—that is found by in the feed speed calculator block


83


—by the correction data calculator


89


in the correction time calculator block


88


to find the correction time Δt (=ΔS/V).




(8) Then, the intially set recording start time t is read from the feed time setting block


92


, and the correction feed time t′=t+Δt is found in the correction feed time calculator


90


by the correction time Δt. The correction feed time t″ is then renewed in the feed time setting block


92


in place of the initially set feed time t.




(9) After that, the ticket blank


1




a


is fed to the printer unit


6


where the correction value (i.e., ΔS) is printed for issuance through an issuance port. This enables the operator to confirm the quantity of regulation. Finally, the correction-mode indicating button


260


is again pressed down to release the correction mode, making the correction of the recording start position complete.




After the passing of the time t′ from the time the sensor SS detects the leading end of the ticket blank


1




a


, the write head


50


starts to write the data with the use of the thus corrected write start time (feed time) t′, whereby the data is written onto the ticket blank


1




a


from the position away from the leading end by the given distance L


1


. Such correction is usually done when hardware is forwarded from plants or in-situ replacement of the whole or a part of the MS unit


5


.




Therefore, the instant embodiment can dispense with some post-data-recording steps of development, measurement and regulation that are required for conventional correction procedures, and so can eliminate troublesome development and measurement works and works for regulating the distances of the sensor SS and write head


50


for correcting the recording start position on the ticket blank


1




a.






While the instant embodiment has been described as making correction only when the difference ΔS, when found, exceeds the allowable value S


L


, it is understood that only the feed time Δt corresponding to the difference ΔS may be corrected irrespective of the allowable value S


L


.




As many apparently widely different embodiments of the present invention can be made without departing from the spirit and scope thereof, it is to be understood that the invention is not limited to the specific embodiments thereof except as defined in the appended claims.
