Such a structure is suitable for a card having a uniform thickness, but a developer pod for spreading a developer between sheets of instant photographs for forming a photograph, and a surplus in that case It is not suitable for instant photography in which a trap portion for collecting the developer is formed, and the portion where the developer pod and the trap portion are formed is swollen (for example, see Patent Document 2). That is, when such an instant photograph is to be sealed by the sealing device disclosed in Patent Document 1, not only the photograph carrying portion but also the developer pod and the trap portion are strongly pressed, and thus the developer pod and the trap portion. There is a problem that the developing solution remaining in the solution will ooze out and stain the photograph and the sealing device.

  An object of the present invention is to provide a sealing device that can effectively prevent the developer from seeping out.

The first means is
A sealing device for sealing a surface of an instant photograph having a developer pod formed at one end in the X direction along one side of a rectangular outer shape and a trap formed at the other end with a laminate film,
A base having an abutment surface for abutting the back surface of the instant photo and mounting the instant photo;
A pair of cylindrical rollers that pull in the instant film and the laminated film placed on the base at the same time to bond the laminated film to the surface of the instant film,
Equipped with
The contact surface is configured so that the instant photograph can be placed so that the X direction matches the direction orthogonal to the pull-in direction,
At least one roller of the pair of rollers has an intermediate portion having a constant diameter that is brought into contact with the instant photograph, and has side portions corresponding to the developing solution pod and the trap portion that are larger than the intermediate portion. A small diameter portion having a small diameter is formed, and the formation portion of the developer pod and the trap portion of the instant photograph can be received in a space between the small diameter portion and the other roller. ..
Here, the "formation portion of the developer pod and the trap portion" is not limited to the developer pod and the trap portion itself, and also includes a main body portion of an instant photograph provided with the developer pod and the trap portion. Further, the roller forming the small diameter portion may be a roller contacting the front side of the instant photograph or a roller contacting the back side of the instant photograph. Further, the small diameter portion may be formed on only one roller or may be formed on two rollers.

  The second means is the first means, and at both ends of the one roller, a forming portion having a large dimension in the X direction among the forming portions of the developer pod and the trap portion is the other. The small diameter portion having a width that can be received between the roller and the roller is formed.

  A third means is the first means or the second means, wherein the other roller is a roller that is brought into contact with the front surface of the instant photograph, and the one roller is the back surface of the instant photograph. It is a roller that is in contact with.

  A fourth means is any one of the first means to the third means, and a portion corresponding to a moving area of the developer pod and the trap portion is provided on the contact surface. It is characterized in that it has a groove that can receive the liquid pod and the trap portion.

  A fifth means is the fourth means, wherein both ends of the contact surface can receive a portion of the developer pod and the trap portion having a large dimension in the X direction. The groove having the width is formed.

  According to the first means, since the developer pod and the trap portion forming portion of the instant photograph can be received in the space between the small diameter portion and the other roller, the pair of rollers can be used. The developer pod and the trap portion are not strongly pressed, and the developer can be prevented from seeping out from the developer pod and the trap portion.

  According to the second means, at both ends of the one roller, the formed portion of the developer pod and the trap portion having the larger dimension in the X direction can be received between the one roller. Since the small-diameter portion having a wide width is formed, the exudation of the developing solution from the developing solution pod and the trap section can be prevented even when the front and rear of the drawing direction of the instant photograph is reversed.

  According to the third means, the roller on which the small diameter portion is formed is the roller which is brought into contact with the back surface of the instant photograph, so that the developer pod and the trap portion are fitted into the small diameter portion while the instant photograph is taken. Since the surface of the laminate is kept flat, the laminated film does not bend and a clean seal can be performed.

  According to the fourth means, since the portion corresponding to the developer pod and the trap portion is a groove on the contact surface of the instant photo, the developer pod and the trap are not formed when the instant photo moves on the contact surface. The trap part does not come into strong sliding contact. Therefore, it is possible to prevent the developer pod and the trap portion from being damaged.

  According to the fifth means, a groove having a width that allows a portion of the developer pod and the trap portion having a large dimension in the X direction to be received is formed at both ends of the contact surface. The developer pod and the trap portion can be prevented from being damaged even if the instant photograph is turned upside down.

The right end of the shaft 50a of the roller 50 projects from the wall 33, and a dial knob 53 is attached to the projecting portion. A one-way clutch (not shown) is interposed between the dial knob 53 and the shaft 50a, and the roller 50 is rotationally driven only when the dial knob 53 is rotated in one direction.
The lower roller 51 is formed in a cylindrical shape so that it can support the entire area of the 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. The left and right small-diameter portions 51b have the same length (width) along the axial direction. In this case, the width is such that one of 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 received. This is so that it can be dealt with even when the front and back of the pull-in direction of the instant photograph 10 is reversed. The roller 51 configured as described above is configured to be able to idle around the shaft 51a, and cooperates with the roller 50 to draw in the instant photograph 10 and the laminated film 20. The roller 51 may be biased toward the roller 50 by a spring.
The diameter of the small-diameter portion 51b is preferably set so that the portion where the developer pod 13 and the trap portion 14 are formed can be exactly accommodated in the space between the small-diameter portion 51b and the roller 50.

5. Positioning Mechanism 60 As shown in FIG. 3, stoppers 60 and 60 protruding and retracting from the contact surface 35 are provided in the inner part of the pair of rollers 50 and 51 so as to be laterally distributed. The stoppers 60, 60 are attached to the movable plate 62, as shown in FIG.
