Design Registration No. 1508035 JP 2006-018041 A

However, in the sealing device disclosed in Patent Document 1, each of the pair of rollers is cylindrical, and is configured to uniformly press the entire width of the drawn card.
Such a configuration is suitable for objects having a uniform thickness such as cards, but a developer pod for spreading the developer between sheets of instant photographs to form a photograph, and the excess at that time It is not suitable for instant photography in which a trap portion is formed for collecting the developer, and the portion where the developer pod and the trap portion are formed swells (see, for example, Patent Document 2). That is, when an attempt is made to seal such an instant photograph with the sealing device disclosed in Patent Document 1, not only the photograph holding portion but also the developer pod and trap portion are strongly pressed against each other. There is a problem in that the developer remaining in the film oozes out and stains the photograph and the sealing device.

SUMMARY OF THE INVENTION An object of the present invention is to provide a sealing device that can effectively prevent the bleeding of developer.

The first means is
A sealing device for sealing the surface of an instant photograph with a laminate film, having a developer pod formed at one end in the X direction along one side of a rectangular outline and a trap portion formed at the other end, the sealing device comprising:
a base having a contact surface on which the instant photograph is placed in contact with the back surface of the instant photograph;
a pair of cylindrical rollers for simultaneously pulling in the instant photo placed on the base and the lamination film to adhere the lamination film to the surface of the instant photo;
with
the abutment surface is configured to allow the instant photograph to be placed thereon so that the X direction coincides with the direction orthogonal to the retraction direction;
At least one roller of the pair of rollers has a middle portion that abuts on the instant photograph having a constant diameter, and has both side portions corresponding to the developer pod and the trap portion that are wider than the middle portion. A small-diameter portion having a small diameter is formed, and the portion where the developer pod and the trap portion of the instant photograph are formed can be received in the space between the small-diameter portion and the other roller.
Here, the "portion where the developer pod and the trap section are formed" includes not only the developer pod and the trap section themselves, but also the main portion of the instant photograph to which the developer pod and the trap section are attached. Further, the roller forming the small-diameter portion may be a roller that contacts the front side of the instant photo, or may be a roller that contacts the back side of the instant photo. Furthermore, the small-diameter portion may be formed on only one roller, or may be formed on two rollers.

A second means is the first means, wherein, of the forming portions of the developer pod and the trap portion, the forming portion having the larger dimension in the X direction is formed on both ends of the one roller. The small-diameter portion is formed with a width that can be received between the rollers.

A third means is the first means or the second means, wherein the other roller is a roller in contact with the front surface of the instant photograph, and the one roller is the rear surface of the instant photograph. It is characterized by being a roller that abuts against.

A fourth means is any one of the first to third means, wherein the abutment surface has a portion corresponding to the movement area of the developer pod and the trap section. A groove is provided to receive the liquid pod and the trap portion.

A fifth means is the fourth means, wherein both end portions of the abutment surface are capable of receiving a portion of the developer pod and the trap portion having a large dimension in the X direction. The width of the groove is formed.

According to the first means, the developer pod of the instant photograph and the portion where the trap portion is formed can be received in the space between the small-diameter portion and the other roller. The developer pod and the trap section are not pushed strongly, and the developer can be prevented from seeping out from the developer pod and the trap section.

According to the second means, at both ends of one roller, of the formation portions of the developer pod and the trap portion, the formation portion having a large dimension in the X direction can be received between the one roller and the roller. Since the small-diameter portion having such a width is formed, it is possible to prevent the developing solution from seeping out from the developing solution pod and the trap portion even if the instant photograph is reversed in the drawing direction.

According to the third means, the roller formed with the small diameter portion is a roller that abuts against the back surface of the instant photograph. Since the surface of is maintained flat, the laminate film does not bend and a clean seal can be obtained.

According to the fourth means, since the portion corresponding to the developer pod and the trap section is formed on the contact surface of the instant photograph, the developer pod and the trap portion are formed when the instant photograph moves on the contact surface. The trap part is not strongly slidably contacted. Therefore, it is possible to prevent the developer pod and the trap portion from being damaged.

According to the fifth means, grooves are formed at both ends of the abutment surface and have a width capable of receiving a portion of the developer pod and the trap portion having a large dimension in the X direction. Damage to the developer pod and the trap section can be prevented even if the instant photograph is reversed from front to back in the drawing direction.

1. About Instant Photo 10 As shown in the left of FIG. A developer pod 13 is formed on the back side of the blank portion 12 located at one end in the X direction of the instant photograph 10, and a trap portion 14 is formed on the back side of the blank portion 12 located at the other end. The thickness of the developer pod 13 and the trap portion 14 is greater than the thickness of the photograph portion 11 . Specifically, as shown on the right side of FIG. 4, the portions of the developer pod 13 and the trap portion 14 bulge out on the rear surface of the instant photograph 10 .

2. Laminate Film 20 The laminate film 20 is used to protect or decorate the surface of the instant photograph 10 .
As shown in FIG. 5, the laminate film 20 has the same shape as the instant photograph 10 so that it can be adhered to the entire surface of the instant photograph 10 . A backing paper 21 for protecting the adhesive surface is attached to the back surface (adhesive surface) of the laminate film 20 . The mount 21 is separated into two in the laminate film 20 of the embodiment. One is a band-shaped mount 21a corresponding to the front end portion of the laminate film 20 in the feed direction (pull-in direction), and the other is a rectangular mount 21b corresponding to the remaining portion of the laminate film 20. FIG. The mount 21 a is peeled off before the instant photograph 10 is placed on the sealing device 100 . Then, the adhesive surface of the laminate film 20 exposed by peeling the mount 21 a is adhered to one side of the instant photograph 10 . Also, the mount 21b is peeled off during the process of sealing the surface of the instant photograph 10 with the sealing device 100 .

3. About the Base 30 The base 30 is for placing the instant photograph 10 to be sealed when sealing.
As shown in FIG. 1 and the like, the base 30 includes a plate-shaped mounting portion 32 that constitutes a portion for mounting the instant photograph 10 , and a plate-like mounting portion 32 that is arranged on the left and right sides of the mounting portion 32 and is positioned above the mounting portion 32 . and protruding walls 33,33. A contact surface 35 is formed on the upper surface of the mounting portion 32 with which the back surface of the instant photograph 10 mounted on the mounting portion 32 is brought into contact. The contact surface 35 is partitioned in three directions (front and left and right) by edges 35 a that slightly project upward from the contact surface 35 .
As shown in FIG. 6, the mounting section 32 is composed of a body section 320 on the back side and a drawer section 321 on the front side. A front end portion of the drawer portion 321 constitutes a grip portion 321a. An insertion portion 321b is connected to the back side of the grip portion 321a. The gripping portion 321 a abuts on the front side of the body portion 320 when the drawer portion 321 is pushed into the body portion 320 . On the other hand, when the drawer portion 321 is pushed into the body portion 320, the insertion portion 321b slips under the upper plate of the body portion 320 (see FIG. 1). The reason why the mounting portion 32 has a drawer structure is to accommodate two types of instant photographs 10 having different dimensions in the Y direction perpendicular to the X direction.
Further, grooves 36 extending in the depth direction are formed in the left and right ends of the contact surface 35 . The depth of the groove 36 is approximately the same as the amount of protrusion of the developer pod 13 and the trap portion 14 from the rear surface of the instant photograph 10 . Note that the two grooves 36, 36 have the same groove width. In this case, the width of the groove is such that the developer pod 13 and the trap portion 14 having the larger dimension in the X direction (the developer pod 13 in the embodiment) can be accommodated. This makes it possible to handle even when the front and back of the pull-in direction of the instant photograph 10 is reversed.

A right end portion of the shaft 50a of the roller 50 protrudes from the wall 33, and a dial knob 53 is attached to the protruding portion. A one-way clutch (not shown) is interposed between the dial knob 53 and the shaft 50a, and the roller 50 is driven to rotate only when the dial knob 53 is rotated in one direction.
The lower roller 51 is formed in a cylindrical shape so as to cover the entire surface of the instant photograph 10 in the X direction. However, on the left and right sides of the roller 51, small diameter portions 51b are formed at locations corresponding to the developer pod 13 and the trap portion 14 of the instant photograph 10. As shown in FIG. The length (width) along the axial direction of the left and right small diameter portions 51b is the same. In this case, the width is such that the developer pod 13 and the trap portion 14, whichever has the larger dimension in the X direction (the developer pod 13 in the embodiment) can be accommodated. This makes it possible to handle even when the front and back of the pull-in direction of the instant photograph 10 is reversed. The roller 51 constructed in this manner is rotatable around a shaft 51a, and cooperates with the roller 50 to pull in the instant photograph 10 and the laminate film 20. As shown in FIG. Note that the roller 51 may be biased toward the roller 50 by a spring.
The diameter of the small-diameter portion 51b is preferably such that the portion where the developer pod 13 and the trap portion 14 are formed can be just accommodated in the space between the small-diameter portion 51b and the roller 50. FIG.

5. Positioning Mechanism 60 Behind the pair of rollers 50 and 51, as shown in FIG. The stoppers 60, 60 are attached to a movable plate 62 as shown in FIG. The movable plate 62 is biased upward by, for example, a spring (not shown), and the left and right stoppers 60, 60 protrude upward from the contact surface 35 when the lid 40 is open. The instant photograph 10, which has been passed between the pair of rollers 50 and 51, is brought into contact with the projecting left and right stoppers 60, 60 so that the instant photograph 10 is positioned.
