Passbook transport mechanism

A passbook transporting or conveying mechanism has front gripping rollers for gripping the passbook in unprinted areas thereof and for moving the passbook to a printing station. The front gripping rollers are caused to be moved along guide rods in a rearward direction by driving wires or cables connected to roller supports. The passbook is received by rear gripping rollers which are caused to be moved along guide rods in a further rearward direction by driving wires or cables connected to roller supports to a predetermined position for reading a magnetic stripe on the back cover of the passbook. The magnetic stripe on the passbook is read out and the passbook is moved forward to position the passbook at the printing station for the printing operations on the desired print line or lines. After the printing operations, the passbook is again moved rearward to record the printed information in the magnetic stripe. The passbook is then moved in a forward direction to the front gripping rollers for exit from the printer.

BACKGROUND OF THE INVENTION 
In the field of financial-type business transactions, a commonly used 
record medium is a passbook or bankbook for maintaining a record of each 
transaction. The passbook is inserted into a business machine for reading 
the contents of the passbook, for printing information or data in the 
passbook, and for recording the printed information or data in the 
passbook. 
In the operation of the business machine for passbook printing therein, the 
passbook is inserted at the front of the machine and the passbook is then 
transported or conveyed past a printing station toward the rear of the 
machine where the current status of the record is read by means of 
read/write mechanism from a magnetic strip on the passbook. The passbook 
is then transported to the printing station for printing operation after 
which the passbook is again transported toward the rear of the machine 
where the printed information is recorded by means of the read/write 
mechanism in a write operation on the magnetic stripe. The passbook is 
then transported toward the front and out of the business machine. 
In prior mechanisms there have generally been two types of means for 
conveying a printed medium such as a bankbook to predetermined positions 
in a printer to enable the required operations. One type of conveying 
means uses pairs of rollers spaced from each other and disposed at spaced 
intervals along the path of the bankbook and rotatably engaged with the 
book. Another type of conveying means uses rotating rollers provided on 
both sides of a feed path and belts driven by the rotating rollers and 
engageable with the book.

DESCRIPTION OF THE PREFERRED EMBODIMENT 
FIG. 1 is a perspective view of a portion of printing mechanism, generally 
designated as 10, for printing on a record medium such as a passbook 12. 
The printing mechanism or printer 10 has an insert or entrance port 14 at 
one end thereof for receiving the passbook 12 for processing a printing or 
recording operation. The insert port 14 is located at the front of the 
printer 10. A shutter or like member (not shown) is provided at a 
predetermined distance from the insert port 14. The shutter is in a 
normally closed position in the printer 10 and is engaged by an end 16 of 
the passbook 12 when the passbook is inserted into the receiving end or 
insert port 14 of the printer 10. A sensor 18 having an upper portion 20 
and a lower portion 22 is supported in a position to detect the insertion 
of the passbook 12. The sensor 18 may comprise a limit switch, a 
photosensor or like element supported and connected in suitable manner to 
detect the presence of the passbook 12. 
When the passbook 12 is detected by the sensor 18, a printer controller 
(not shown) causes a lower roller 24 to be moved toward an upper roller 26 
by means of a solenoid 25 or other actuating device. The passbook 12 is in 
position to be gripped by the upper roller 26 and the lower roller 24, 
designated as front grip rollers, in marginal areas of the passbook which 
are not used in the printing and/or recording operations. The rollers 24 
and 26 are coated with a material having high frictional characteristics 
such as rubber or the like so as to firmly grip and thus maintain the 
passbook 12 in precise position between the rollers 24 and 26. The upper 
roller 26 is designed to perform as a drive roller by means of being 
supported on a rotatable shaft 28 in order to be conveyed or transported 
toward the rear of the printer 10. The lower roller 24 performs as an 
idler roller and freely rotates on a shaft 30. Frictional contact of the 
two rollers and driving the upper drive roller 26 causes the lower roller 
24 to be rotated by the upper roller. The correct amount of rotational 
loading on the lower roller 24 is maintained so as to prevent the passbook 
12 from moving down and away from the upper roller 26 during transport of 
the passbook 12. After the passbook 12 has been gripped by the rollers 24 
and 26, the controller opens the shutter to allow the passbook 12 to be 
transported toward the rear of the printer 10. 
The rollers 24 and 26 are supported by brackets 32 and 34 which in turn are 
carried on lower rods or shafts 36, 38 and on upper rods or shafts 40, 42, 
respectively. The rollers 24 and 26 are moved in parallel manner along a 
feed path for the passbook 12 while such rollers are gripping the 
passbook. A driving wire or cable 44 is secured by means of a clip 46 to 
the upper bracket 34 and a driving wire or cable 48 is secured by means of 
a clip 50 to the lower bracket 32 for moving the brackets 32, 34 and the 
rollers 24, 26 along the passbook feed path. The driving wires or cables 
44 and 48 are connected to appropriate drive means (not shown) for moving 
the rollers 24 and 26 along the feed path for transporting the passbook 
toward and from the printing station. This structure provides an 
arrangement wherein the upper roller 26 and the lower roller 24 move 
parallel with each other along the feed path of the passbook 12 while 
maintaining their relative positions. 
FIG. 2A is a view of the passbook 12 in open condition at the fold line 51 
and FIG. 2B is a view of the front and back covers of the passbook 12 in a 
turned over condition from that of FIG. 2A. The passbook 12 is inserted 
into the port 14 at the front of the printer 10 in the open condition, as 
shown in FIG. 2A. An upper portion 52 of the passbook 12 is shown as 
having printed matter in five lines out of eleven lines thereof and a 
lower portion 54 is shown as having twelve blank lines. The upper portion 
52 includes appropriate headings such as the date, repayment, deposit, 
balance and the like which are common terms used in financial 
transactions. 
A bar code or like marking 56 is provided at the upper left corner of the 
upper portion 52 of the passbook 12 and such bar code 56 indicates the 
number of the page of the passbook 12. The front cover 58 (FIG. 2B) of the 
passbook 12 includes appropriate information regarding the identification 
of the holder of the passbook 12. A magnetic stripe 62 is provided at the 
lower edge of the back cover 60. The magnetic stripe 62 contains 
information or data such as an identification code, information or data 
regarding previous transactions and like information. The page number of 
the passbook 12, as indicated by the bar code 56, is read out when the 
passbook is inserted into the port 14 of the printer 10 and when the 
passbook 12 is disposed at a predetermined position in preparation for a 
transaction. 
An upper roller 64 and a lower roller 66 (FIG. 1), designated as rear grip 
rollers, are provided at the rear of the printer 10. The lower roller 66 
is coated with a material having high frictional characteristics such as 
rubber or the like so as to firmly grip the passbook 12. The upper roller 
64 is covered over approximately one-half the periphery thereof with 
rubber and the other one-half is not covered and is exposed metal. 
The upper rear grip roller 64 is supported by a bridge member 72 which is 
carried on outer rods 74 and 76. Additional supporting structure 78 for 
the lower rear grip roller 66 is carried on rods 80 and 82 located between 
the outer rods 74 and 76. A pair of opposed rollers, an upper roller 68 
and a lower roller 70, are positioned in an area between the front grip 
rollers 24 and 26 and the rear grip rollers 64 and 66. The opposed rollers 
68 and 70 are carried on transverse rods or shafts 84 and 86. As shown in 
FIG. 1, a right upper roller 68 and a right lower roller 70 are carried on 
the shafts 84 and 86 and are spaced from the rollers 68, 70 at the left 
side of the shafts. 
The drive roller 26 of the front grip rollers is positively rotated to feed 
or transport the passbook 12 to the opposed rollers 68 and 70. Since the 
lower roller 24 is an idler roller, such roller is free to rotate during 
movement of the passbook 12 toward the rear of the printer 10. It is also 
noted that the passbook 12 is transported in the rearward direction by the 
driving force of the front grip rollers 24 and 26 and that the opposed 
rollers 68 and 70 are freely rotating rollers which receive and guide the 
passbook 12 along its feed path. The upper roller 64 of the rear grip 
rollers is a drive roller to positively receive and convey the passbook 
12. The lower roller 66 is an idler roller and is movable toward and from 
the upper roller 64. 
A sensor (not shown) is provided in a position adjacent the rear grip 
rollers 64 and 66 to detect the presence of the passbook 12. A controller 
(not shown) is responsive to operation of the sensor to move the lower 
roller 66 toward the upper roller 64 and cause the rollers to grip the 
passbook 12. The upper roller 64 and the lower roller 66 are constructed 
in a manner to facilitate a page turning operation of the passbook 12. 
The rear grip rollers 64 and 66 are moved in parallel with each other 
toward the rear of the printer. A driving wire or cable 88 is secured by 
means of a clip 90 to the bridge member 72 and a driving wire or cable 92 
is secured by means of a clip 94 to the structure 78 for moving the bridge 
member 72 and the structure 78 with rollers 64 and 66 along the feed path 
of the passbook 12. The driving wires or cables 88 and 92 are connected to 
appropriate drive means (not shown) for moving the rollers 64 and 66 along 
the feed path for transporting the passbook toward and from the printing 
station. This arrangement provides that the upper roller 64 and the lower 
roller 66 move parallel with each other along the feed path of the 
passbook 12 while maintaining their relative positions. The parallel 
movement of the rollers 64 and 66 is realized by reason of the 
simultaneous movement of the driving wires 88 and 92. 
The passbook 12 is moved toward the rear of the printer 10 to a position as 
shown in phantom lines in FIG. 1. The recorded contents of the magnetic 
stripe 62 on the back cover of the passbook 12 are read out by a read head 
96 of a magnetic reader adjacent the printing station. It is to be noted 
that the read head 96 of the reader can read out the contents of the 
magnetic stripe 62 under conditions of traversing operation of a print 
head 98 of the printer 10. The traversing movement of the print head 98 
along with a platen 100 is effected by means of a motor 102 driving a belt 
104 trained around pulleys 103 and 105 and coupled with a lead screw 106. 
A right hand bracket 108 is coupled to the lead screw 106 and to a shaft 
110 which carries the platen 100, and a left hand bracket 112 is coupled 
to the lead screw 106 and to the shaft 110. The brackets 108 and 112 
engage with respective cams 114 and 116 on a cross shaft 118. A motor 120 
is coupled by means of a gear 121 and a gear 122 to rotate the shaft 118. 
Rotation of the shaft 118 enables rotation of the brackets 108 and 112 
wherein the brackets are located in a lower position while the passbook 12 
is being transported along the feed path. Rotation of the shaft 118 
rotates the brackets 108 and 112 to a position wherein the brackets are 
located in an upper position when the contents of the magnetic stripe 62 
are being read and/or recorded or when printing operations are being 
performed. 
After the contents of the magnetic stripe 62 have been read out, the 
passbook 12 is transported in a direction toward the front of the printer 
10 by means of the driving wires 88 and 92. The passbook 12 is stopped at 
the printing station in a position wherein print line 124 (line 6 of the 
page of the passbook) is placed in alignment with or under the print head 
98. FIG. 2A shows line 6 of the page as being the next print line 124 for 
receiving printed matter. This position of the passbook 12 is recorded in 
the magnetic stripe 62 and the printer controller thus has advance notice 
for the next operation. The printing position is also noted by the 
photosensor adjacent the rear grip rollers 64 and 66 when the passbook 12 
is transported along the feed path. 
The passbook 12 is placed in the printing position for printing of data on 
a predetermined number of lines and printing is accomplished by traversing 
movement of the print head 98 and the platen 100. 
Line feeding of the passbook 12 to enable printing on additional lines by 
the print head 98 is accomplished by operation of the rear grip rollers 64 
and 66. If additional printing of data on another line or other lines is 
required to complete the transaction after having printed the last line on 
the page, it is necessary to turn to the next page of the passbook 12. 
The page turning operation is performed by controlling the movement and 
rotation of the rear grip rollers 64 and 66. The lower grip roller 66 is 
moved toward the rear of the printer 10 a predetermined distance 
independently of the upper grip roller 64. The predetermined distance is 
set so as to have the roller 66 positioned at a location for turning up or 
curving a portion of the passbook 12. The upper roller 64 is then rotated 
one revolution to spring up one page of the passbook 12 in a rearward 
direction and then to return the passbook to its original flat condition. 
The bridge member 72 is then moved rearward to align the upper roller 64 
with the lower roller 66. The rollers 68 and 70 grip the pages of the 
passbook 12 so that only one page can be turned in this operation. In this 
regard, the rear grip rollers 64 and 66 can provide a page turning 
operation in addition to the passbook transport operation. The details of 
the turning operation are described in U.S. Pat. No. 4,995,184. 
At the completion of the printing operation, the passbook 12 is again moved 
rearward and the necessary data are recorded in the magnetic stripe 62. In 
this manner, the printing operation and the associated reading and 
recording operations are accomplished. The passbook 12 is then transported 
from the rear grip rollers 64 and 66 to the rollers 68 and 70 and then to 
the front grip rollers 24 and 26, and out the port 14 at the front of the 
printer 10. 
FIG. 3 is a perspective view showing passbook conveying mechanism in a 
conventional printer. One type of conveying means uses a plurality of 
pairs of opposed rollers 130 and 132, disposed along one side of the path 
of a passbook 134. A plurality of pairs of opposed rollers 136 and 138 are 
disposed along the other side of the path of the passbook 134. The pairs 
of rollers 130, 132 and 136, 138 are spaced from each other and additional 
pairs of such rollers are disposed at spaced intervals along the path of 
the passbook 134. 
The rollers 130 and 136 are in fixed position on a shaft 131 and the 
rollers 132 and 138 are carried on arms 140 and 142, secured to a shaft 
144. The rollers 132 and 138 are suitably journaled on the arms 140 and 
142. A solenoid or like actuator 146 is connected to the shaft 144 by 
links 148 and 150 for rotating the shaft to provide space between the 
respective rollers for passage of the passbook 134. The solenoid 146 
operates against the action of a spring 152. A platen 154 and a print head 
156 are positioned at the printing station for performing printing 
operations on the passbook 134. 
The passbook 134 or like print medium conveying means of the prior art 
utilizes a frictional force generated between the respective pairs of 
rollers 130, 132 and 136, 138. In another type of conveying means, if 
belts are used, the frictional force is also relied on to convey the 
passbook 134. The conveying of the passbook 134 depends on certain 
unstable factors such as uneven surfaces of the rollers, variation in 
material of the belt, or dust particles or moisture on the belt. Also, the 
passbook 134 or other print medium may jam in the printer or may be 
conveyed at an angle and the printing may not be done at the precise print 
line or may be done on a slant. 
Additionally, the rollers or belts are in direct contact with the surface 
of the print medium on which information or data are to be printed. Since 
the printed medium is conveyed immediately after the printing operation, 
the printing ink on the surface of the printed medium may not be dry and 
smears or stains may result. Further, it is seen that a plurality of 
rollers and/or belts are necessary along the conveying path of the 
passbook and the increased number of components adds to the cost of 
manufacturing the passbook printer. 
The present invention provides gripping rollers which grip the passbook and 
convey or transport the passbook by moving the gripping rollers along the 
path of the passbook. The two gripping rollers tightly grip the passbook 
and feed or convey the passbook in a stable condition, so that jamming, 
slant feeding and slant printing are eliminated. The gripping rollers are 
not in contact with the printed surface of the printed medium so as to 
avoid smearing or staining of such medium. An alternative to the gripping 
rollers may include two plate members constructed such that one plate 
member is pivotally supported and the plate members are opened and closed 
by actuating means so as to grip the passbook during transporting thereof 
along a path in the printer. 
It is thus seen that herein shown and described is a passbook transport 
mechanism wherein two rollers grip a surface area of a passbook or like 
print medium on which no data or information are printed and the rollers 
are moved in parallel to feed the passbook along a feed path through the 
printer. The passbook is conveyed along such feed path in a stable 
condition and the printed surface area is never in contact with the 
gripping rollers. 
The structure and arrangement enable the accomplishment of the objects and 
advantages mentioned above, and while the preferred embodiment of the 
invention has been disclosed herein, variations thereof may occur to those 
skilled in the art. It is contemplated that all such variations not 
departing from the spirit and scope of the invention hereof are to be 
construed in accordance with the following claims.
