Next, a method of manufacturing the postcard will be explained.
First, continuous paper for forming the postcard stuff 10 is prepared. The postcard material 12 portion and the base materlal 18 portion are formed continuously in the direction of width of this continuous paper. Accordingly, the length of the continuous paper in the direction of width is a sum of the length of the postcard material 12 and the lenyth of the base material 18. And the suppression layer 20 is formed on one main surface of the base material 18 of the continuous paper by allover printing with a silver ink, for : 1,: . I ;
example, by the known printing method as the offset printing or coating.
As showing Fig. 3, a rolled laminate comprising the : . :
postcard stuff 10 formed with the suppression layer 20 -~
:~ ' ~ .
~" 2~2~
is mounted on a hold roller 32 of a manufacturing machine 30 for the covering material.
The postcard stuff 10 held by the hold rc>ller 32 is loosen at one end and led to a resin coater 34. The resin coater 34 is designed to print and coat the resin 22a such as the aforesaid vinyl chloride-vinyl acetate copolymer on - ,:
the suppression layer 20 of the base material 18.
The base material 18 onto which the resin 22a is printed and coated is then guided to a dryer 36, whereby the resin 22a is dried and the primer layer 22 is formed.
Next, the base material 18 -formed with the primer layer 22 is directed to a heat adherent resin coa~er 40 for printing and coating the heat adherent resin 24a containing, for example, the aforesaid ethylene-vinyl acetate copolymerized resin as a main component. The heat adherent resin coater 40 is a printing or coating machine utilizing known printing and coating methods such as a typographic printing, gravure printing, silk screen printing, o-ffset printing or the like.
By- the heat adherent resln coater 40, the heat adherent resin 24a is printincJ or coating on the surface of the primer layer 22.
The base material 18 onto which the heat adherent resin ~ .
~ 24a lS printed or coated is led to a dryer 42, whereby the ~ -:
heat adherent resin 24a is dried and the first heat adherent "` :'. :' 2 ~
resin layer 24 is formed. -Thus, as shown in Fig. 4, the covering material 14 of the postcard stuff lO is formed with the suppression layer 20, the primer layer 22 and the heat adherent resin layer 24 on the surface of the base material 18.
The continuous postcard stuff lO is wound round a take-up roller 44 ayain.
In this embodiment, as shown in Fig. 2A and Fig. 4, the suppression layer 20 is formed on one main surface of the base material 18, the primer layer 22 is formed on the surface of the suppression layer 20, and the heat adherent resin layer 24 is formed on the surface of the primer layer 22. The adhesion of the heat adherent resin layer 24 is increased by the primer layer 22. Therefore, the heat adherent resin layer 24 is adhered strongly to the base ~::
material 18, and adhered weakly to the postcard material 12.
-~ Wl en the aluminum foil and the like having a ~ood suppressiveness is selected as the base material 18, the suppression layer 20 is not necessary. In this case, the primer layer 22 is formed on one main surface of the base material l8.
Further, as a material of the postcard stuff lO, a ~ -rolled coI1tinuous paper is selected, but a loose paper, that ; is to say, a separated paper may be selected.
~ ~ ~ Also, on the base material 18, any suitable printiny ;~ 14 -: ' :
--~ 2~2~
which fits to properties of the postcard may be perforrned, or when the continuous material is used as aforesaid embodil~ents, for example, a detecting mark(arrow) for detecting feeding pitches of the base material 18 may be printed with a black color or the like.
Subse~uently, this postcard stuff 10 is led to a covering material sticking apparatus stic]cing this covering raaterial 14 to the postcard material 12. At this time, to cover a confidential matter such as a residual amount deposited in a bank which is formed on part of the surface of the postcard with the covering material 14, it is necessary to print proper characters in advance on a proper place, for example, the lower column of the postcard material.
:~ :
~ In addition, in the case of making this covering ~
. ~ ,.
material 14 adhere, for example, to the lower column of the ;~
postcard, as shown in Fig. 5, the postcard stuff 10 is fed sequentially, and it is folded back at the boundary between ~;
the postcard material 12 portion and the covering material 14 portion, and the covering material 14 and the postcard ~ ;~
material 12 are bonded. Then, the surface of postcard stuff 10 is pressed by a pressing roller, and the covering material 14 is stuck to the surface of the postcard material 12. ~ `
Then, the postcard stuff 10 i9 cut in a proper size, and the postcard of the present invention is formed.
In the adhered covering material 14, the adherent resin ;~
: ' ~
','.,.'f', ," ' --` 2~2~
layer 24 is adhered strongly to the kase material 1~, and suppression layer 20 is adh~red wea]~ly to the postcard material 12. Thus, as shown in Fig. lA and Fi~ , the covering material 14 can be peeled off relatively easily from the postcard material 12 by cutting it.
Also, the covering material 14 can be peeled off relatively easily by not cuttins.
And, the lottery part 16a and the confidential matter 16b formed on a ~urface of the postcard material 12 can be seeing.
Fig. 6A and Fig. 6B are views showing an another embodiment Gf the present invention, in which Fig. 6A is a perspective vieu therof, and Fig. 6B is a sectional view thereof.
In this embodiment, cuts 26a and 26b forming with ~;~ parforations are forn~ed specifically in the upside and the downside of the base material 18, the suppression layer 20, the prlmer layer 22 and the heat adherent resin layer 24. The cuts 26a and 26b are formed by a perforator including a cutter roll so-called die roll or by a perforator including~
a die cutter having a cutter blade.
In this embodiment, when the center portion of the covering material 14 in the up-and-down direction is peeled off, as shown in Fig. 7A and Fig. 7B, the center portion can be ~eeled off relatively easily from the postcard material 12 ,: -' :
~0~
:
by cutting the covering material 14 at the cuts 26a and 26b.Then, the lottery part 16a and the confident1al matter 16b on the surface of the postcard rnaterial 12 can be seeing.
Fig. 8A and Fi~y. 8B are perspective views showiny a ;
separate embodiment of the present invention, in which Fig.
8A is a perspective view thereof, and Fig. 8B is a sectional view thereof. In this embodiment, a separate cut 26c is formed specifically in the base material 18, the suppression ;;~
layer 20, the primer layer 22 and the heat adherent resin layer 24 on the inside of the cut 26b. The cut 26c is formed by a die roll together with the cuts 26a and 26b.
Furtherrnore, a half circle cut portion 26d is formed at one end of the base material 18, the suppression layer 20, the primer layer 22 and the heat adherent resin layer 24 in between the cuts 26b and 26c.
In this embodiment, when the center portion of the covering material 14 in the up-and-down direction is peeled off, as shown in Fig. 9A and Fig. 9B, a narrow portion between the cuts 26b and 26c is peeled off, first. In this case, the narrow portion between the cuts 26b and 26c can be peeled off easily by hooking a finger to the cut portion 26dn Then, the lottery part 16a and the confidential matter 16b can be seen by bending the center portion of the covering `~
material 14 in the up-and-down direction at the cut 26a or by cutting it at the cut 26a. `~

In this case, the second heat adherent resin layer 28 may be formed in a fixed width or spots.
Next, a method of manufacturing the postcard shown in Fig. 10 will be explaned.
First, continuous paper for forming the postcard stuff 10 is prepared. The postcard material 12 portion and the base material 18 portion are formed continuously in the direction of width of this continuous paper. Accordingly, the length of the continuous paper in the direction of width is a sum of the length of the postcard material 12 and the length of the base material 1~
As showing Fig. 12, a rolled laminate comprising the postcard stuff 10 formed with the suppression layer 20 is mounted on a hold roller 132 of a manufacturing machine 130 for the covering material.
The postcard stuff 10 held by the hold roller 132, is loosen at one end and led to a resin coater 134. The resin coater 134 is designed to print or coat the resin 27a such as the aforesaid vinyl chloride-vinyl acetate copolymer on the ~..;.....
~`; 2~2$~
suppression layer 20 of the base material 18.
The base material 18 onto which the resin 22a is printed or coated is then guided to a dryer 136, whereby the resin 22a is dried and the primer layer 27 is formed.
NeY.t, the postcard stuff 10 forrned with the primer layer 27 is directed to a heat adherent resin coater 140 for printing or coating the heat adherent resin 28a with a weak adhesion containing, for example, the aforesaid ethylene-vinyl acetate copolymerized resin as a main component. The heat adherent resin coater, 140 is a printing or coating machine utilizins known printing and coating methods such as a typographic printins, gravure printing, silk screen printing, offset printing or the like.
By the heat adherent resin coater 140, the heat adherent resin 28a having a weak adhesive power is printing or coating on the surface of the primer layer 27.
The postcard stuff 10 onto which the heat adherent resin 28a is printed or coated is led to a dryer 142, whereby the heat adherent resin 28a is dried and the first heat adherent resin layer 28 is formed.
Then, the postcard stuff 10 formed with the first heat adherent resin layer 28 or the like led to a heat adherent resin coater 144 for printing or coating- the heat adherent ~ resin 29a having the strong adhesion. The heat adherent resin .~; .
coater 144 is a printing or coating machine utilizing known : `
-`' 2~2~'Z~, ~
printing and coating methods such as a typoZ~raphic printing, gravure printin4, silk screen printing, offset printing or the like. By the heat adherent resin coater 144, the heat adherent resin 29a having the strong adhesion is printed or coated partially on the surface of the first heat adherent resin layer 28.
The postcard stuff 10 onto which the heat adherent resin 29a is printed or coated is led to a dryer 146, whereby the . .
adherent resin 29a is dried and the second heat adherent ~ `
resin layer 29 is formed. ~ ~ , Thus, as shown in Fig. 10, the postcard stuff 10 is ;
formed with the base material 18 on which the suppression `~

suppression layer 20, and the first heat adherent resin layer ~-~. Z` l ~ ~ , Z ~ ; .
28 is formed on the surface of the primer layer 27. The ;~
adhesion of the first heat adherent resin layer 28 is increased by the primer layer 27. Therefore, the first heat -adherent resin layer 28 is adhered strongly to the base ~ 3 ' ~

material 18.
In this embodirnent, the second heat adherent resin layer 29 is formed on a surface of tlle first heat adherent resin layer 28 in the fixed width at the upside and downside of the covering material 14. Moreover, the second heat adherent resin layer 29 is formed on a surface of the first heat adherent resin layer 28 at right and left ends of the covering material 14 in spots.
Therefore, at a portion which the second heat adherent resin layer 29 is formed, the covering material 14 is adhered to a postcard material 12 strongly, and at a portion which the second heat acherent resin layer 29 is not formed, the covering material 14 is adhered to it weakly.
; Thus, as shown in Fig. ll, at the portion where the second heat adherent resin layer 29 is not formed, the base material 18, the suppression layer 20, the primer layer 27 and the first heat adherent resin layer 23 can be relatively easily cut and peeled off from the postcard material 12.

Next, a method of manufacturing the postcard will be explained.
First, continuous paper for forming the postcard stuff 10 is prepared. The postcard material 12 portion and the base materlal 18 portion are formed continuously in the direction of width of this continuous paper. Accordingly, the length of the continuous paper in the direction of width is a sum of the length of the postcard material 12 and the lenyth of the base material 18. And the suppression layer 20 is formed on one main surface of the base material 18 of the continuous paper by allover printing with a silver ink, for : 1,: . I ;
example, by the known printing method as the offset printing or coating.
As showing Fig. 3, a rolled laminate comprising the : . :
postcard stuff 10 formed with the suppression layer 20 -~
:~ ' ~ .
~" 2~2~
is mounted on a hold roller 32 of a manufacturing machine 30 for the covering material.
The postcard stuff 10 held by the hold rc>ller 32 is loosen at one end and led to a resin coater 34. The resin coater 34 is designed to print and coat the resin 22a such as the aforesaid vinyl chloride-vinyl acetate copolymer on - ,:
the suppression layer 20 of the base material 18.
The base material 18 onto which the resin 22a is printed and coated is then guided to a dryer 36, whereby the resin 22a is dried and the primer layer 22 is formed.
Next, the base material 18 -formed with the primer layer 22 is directed to a heat adherent resin coa~er 40 for printing and coating the heat adherent resin 24a containing, for example, the aforesaid ethylene-vinyl acetate copolymerized resin as a main component. The heat adherent resin coater 40 is a printing or coating machine utilizing known printing and coating methods such as a typographic printing, gravure printing, silk screen printing, o-ffset printing or the like.
By- the heat adherent resln coater 40, the heat adherent resin 24a is printincJ or coating on the surface of the primer layer 22.
The base material 18 onto which the heat adherent resin ~ .
~ 24a lS printed or coated is led to a dryer 42, whereby the ~ -:
heat adherent resin 24a is dried and the first heat adherent "` :'. :' 2 ~
resin layer 24 is formed. -Thus, as shown in Fig. 4, the covering material 14 of the postcard stuff lO is formed with the suppression layer 20, the primer layer 22 and the heat adherent resin layer 24 on the surface of the base material 18.
The continuous postcard stuff lO is wound round a take-up roller 44 ayain.
In this embodiment, as shown in Fig. 2A and Fig. 4, the suppression layer 20 is formed on one main surface of the base material 18, the primer layer 22 is formed on the surface of the suppression layer 20, and the heat adherent resin layer 24 is formed on the surface of the primer layer 22. The adhesion of the heat adherent resin layer 24 is increased by the primer layer 22. Therefore, the heat adherent resin layer 24 is adhered strongly to the base ~::
material 18, and adhered weakly to the postcard material 12.
-~ Wl en the aluminum foil and the like having a ~ood suppressiveness is selected as the base material 18, the suppression layer 20 is not necessary. In this case, the primer layer 22 is formed on one main surface of the base material l8.
Further, as a material of the postcard stuff lO, a ~ -rolled coI1tinuous paper is selected, but a loose paper, that ; is to say, a separated paper may be selected.
~ ~ ~ Also, on the base material 18, any suitable printiny ;~ 14 -: ' :
--~ 2~2~
which fits to properties of the postcard may be perforrned, or when the continuous material is used as aforesaid embodil~ents, for example, a detecting mark(arrow) for detecting feeding pitches of the base material 18 may be printed with a black color or the like.
Subse~uently, this postcard stuff 10 is led to a covering material sticking apparatus stic]cing this covering raaterial 14 to the postcard material 12. At this time, to cover a confidential matter such as a residual amount deposited in a bank which is formed on part of the surface of the postcard with the covering material 14, it is necessary to print proper characters in advance on a proper place, for example, the lower column of the postcard material.
:~ :
~ In addition, in the case of making this covering ~
. ~ ,.
material 14 adhere, for example, to the lower column of the ;~
postcard, as shown in Fig. 5, the postcard stuff 10 is fed sequentially, and it is folded back at the boundary between ~;
the postcard material 12 portion and the covering material 14 portion, and the covering material 14 and the postcard ~ ;~
material 12 are bonded. Then, the surface of postcard stuff 10 is pressed by a pressing roller, and the covering material 14 is stuck to the surface of the postcard material 12. ~ `
Then, the postcard stuff 10 i9 cut in a proper size, and the postcard of the present invention is formed.
In the adhered covering material 14, the adherent resin ;~
: ' ~
','.,.'f', ," ' --` 2~2~
layer 24 is adhered strongly to the kase material 1~, and suppression layer 20 is adh~red wea]~ly to the postcard material 12. Thus, as shown in Fig. lA and Fi~ , the covering material 14 can be peeled off relatively easily from the postcard material 12 by cutting it.
Also, the covering material 14 can be peeled off relatively easily by not cuttins.
And, the lottery part 16a and the confidential matter 16b formed on a ~urface of the postcard material 12 can be seeing.

12 stuck to part of this postcard material 12. The covering material 14 is formed integral with the postcard material 12 in a manner of extending froln one end thereof and is stuck to the postcard material 12 in a folded-back fashion.
A lottery part 16a wherein are shown letters such as "winniny" or "blank" and a confidential matter 16b such as a inforrnation of the finance or the insurance are formed on the surface of the postcard material 12.
The covering material 14 comprises a base material 18 for~ed integral with the postcard material 12 in a manner of extending from one end thereof.
The base material 18 is formed with a relatively soft material such as paper, synthetic resin film and the like which can be cut by a scissors or the like. And on one main surface of the base material 18 a suppression layer 20 is formed.
: , , .
On the surface of the suppression layer 20, a primer layer 27 for increasing an adhesion of a heat adherent resin layer 28 discribed layer is formed. The 2rimer layer 27 is ~;
formed by coating a resin such as vinyl chloride-vinyl acetate copolymer on the surface of the suppression layer 20. - -~

a solvent or despersing in water and the firsts heat adherent resin layer 28 has a weak adhesive strength.
The first heat adherent resin layer 28 is forrned to melt at about 100C to 200C so as to be adhered to the postcard material 12 made of paper or the like with a weak adhesive strength.
As an example of said heat adherent resin having a weak adhesive strength, the same adhesives as adhesives of the aforementioned embodiment shown in Fig. 1 may be selected~
Further, on the surface of the first heat adherent resin layer 28, a second heat adherent resin layer 29 having a strong adhesive strength is forr.ledO In this embodiment, the second heat adherent resin layer 29 is formed at both sides in the lengthwise direction of the postcard material 12, that is, in the fixed width at the upside and downside of the .
covering material 14. ~oreover, tne second heat adherent resin layer 29 is formed at both sides in the breadthwise direction of the postcard material 12, that is, at right and left ends of the covering material 14 in spots. The second heat adherent resin layer 29 is formed by coating a heat adherent resin having a strong adhesive strength, for example adhesives of EVA group, stylene-butadiene-stylene copolymer, stylene-isoprele-stylene copolymer iIl parts.
In this case, for example, the tackifier is mixed more as compared with the heat adherent resin having a weak ~, .
-~ 2~%~
.
adhesive strength or the release agent is mixed less as compared with the heat adherent resin having a weak adhesive strength, in the heat adherent resin having a stron~ adhesive strentgth. The second heat adherent resin layer 29 may be formed at only both sides of upside and downside or both right side and left sides of the coveriny material 14.
In this case, the second heat adherent resin layer 28 may be formed in a fixed width or spots.
Next, a method of manufacturing the postcard shown in Fig. 10 will be explaned.
First, continuous paper for forming the postcard stuff 10 is prepared. The postcard material 12 portion and the base material 18 portion are formed continuously in the direction of width of this continuous paper. Accordingly, the length of the continuous paper in the direction of width is a sum of the length of the postcard material 12 and the length of the base material 1~
As showing Fig. 12, a rolled laminate comprising the postcard stuff 10 formed with the suppression layer 20 is mounted on a hold roller 132 of a manufacturing machine 130 for the covering material.
The postcard stuff 10 held by the hold roller 132, is loosen at one end and led to a resin coater 134. The resin coater 134 is designed to print or coat the resin 27a such as the aforesaid vinyl chloride-vinyl acetate copolymer on the ~..;.....
~`; 2~2$~
suppression layer 20 of the base material 18.
The base material 18 onto which the resin 22a is printed or coated is then guided to a dryer 136, whereby the resin 22a is dried and the primer layer 27 is formed.
NeY.t, the postcard stuff 10 forrned with the primer layer 27 is directed to a heat adherent resin coater 140 for printing or coating the heat adherent resin 28a with a weak adhesion containing, for example, the aforesaid ethylene-vinyl acetate copolymerized resin as a main component. The heat adherent resin coater, 140 is a printing or coating machine utilizins known printing and coating methods such as a typographic printins, gravure printing, silk screen printing, offset printing or the like.
By the heat adherent resin coater 140, the heat adherent resin 28a having a weak adhesive power is printing or coating on the surface of the primer layer 27.
The postcard stuff 10 onto which the heat adherent resin 28a is printed or coated is led to a dryer 142, whereby the heat adherent resin 28a is dried and the first heat adherent resin layer 28 is formed.
Then, the postcard stuff 10 formed with the first heat adherent resin layer 28 or the like led to a heat adherent resin coater 144 for printing or coating- the heat adherent ~ resin 29a having the strong adhesion. The heat adherent resin .~; .
coater 144 is a printing or coating machine utilizing known : `
-`' 2~2~'Z~, ~
printing and coating methods such as a typoZ~raphic printing, gravure printin4, silk screen printing, offset printing or the like. By the heat adherent resin coater 144, the heat adherent resin 29a having the strong adhesion is printed or coated partially on the surface of the first heat adherent resin layer 28.
The postcard stuff 10 onto which the heat adherent resin 29a is printed or coated is led to a dryer 146, whereby the . .
adherent resin 29a is dried and the second heat adherent ~ `
resin layer 29 is formed. ~ ~ , Thus, as shown in Fig. 10, the postcard stuff 10 is ;
formed with the base material 18 on which the suppression `~
: ~ -. ,~-layer 20, the primer layer 27, the first heat adherent resin ;---layer 28 and the second heat adherent resin layer 29 is formed in order.
-: , , The postcard stuff 10 is wound round the take-up roller 148 again.
In this embodiment, as shown in Fig. 10, the suppression layer 20 is formed on one main surface of the base material -~
18, the prirler layer 27 is forrned on the surface of the ;~
suppression layer 20, and the first heat adherent resin layer ~-~. Z` l ~ ~ , Z ~ ; .
28 is formed on the surface of the primer layer 27. The ;~
adhesion of the first heat adherent resin layer 28 is increased by the primer layer 27. Therefore, the first heat -adherent resin layer 28 is adhered strongly to the base ~ 3 ' ~
2~2~
material 18.
In this embodirnent, the second heat adherent resin layer 29 is formed on a surface of tlle first heat adherent resin layer 28 in the fixed width at the upside and downside of the covering material 14. Moreover, the second heat adherent resin layer 29 is formed on a surface of the first heat adherent resin layer 28 at right and left ends of the covering material 14 in spots.
Therefore, at a portion which the second heat adherent resin layer 29 is formed, the covering material 14 is adhered to a postcard material 12 strongly, and at a portion which the second heat acherent resin layer 29 is not formed, the covering material 14 is adhered to it weakly.
; Thus, as shown in Fig. ll, at the portion where the second heat adherent resin layer 29 is not formed, the base material 18, the suppression layer 20, the primer layer 27 and the first heat adherent resin layer 23 can be relatively easily cut and peeled off from the postcard material 12. In this case, at a portion which the second heat adherent resin layer 29 is formed in spots the base rnaterial 18, the suppression layer 20, the primer layer 27 an~ the first heat ,:
adherent resin layer 28 can be relatively easily peeled off ~` Then, the lottery uart 16a and the confidential matter 16b on - the surface of the postcard material 12 can be seeing.
