Abstract

PURPOSE:To improve a template by providing at least two projections which symmetrically project with respect to the center line in the moving direction of a film unit on a tangent line to the window frame of an exposing window on a sheet. CONSTITUTION:At least two projections 60 which project to the outside of a sheet surface are provided on a symmetrical position with respect to the center line of the sheet 10 extending in the moving direction on the tangent line between the rim 24 of the window frame of the exposing window on a side where the moving film unit 16 is heading in a mounted state in a film pack container 12 and this sheet 10. Consequently, in order to mount to the exposing window, both ends of the template sheet are inserted under the frame in front and back of the exposing window; therefore, mounting is easy. When the mounting is finished, the projection 60 is engaged with the window frame, so that the template 10 is prevented from being pulled out with the film unit 16 when the film unit 16 which has already been exposed is pulled out.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an image holding template that carries secondary image information to be imprinted on a film together with a subject image during photography.

(Prior Art) When taking photographs with a so-called instant camera, an image holding template is attached to cover the exposure window of the film pack container, and secondary image information is imprinted onto the film along with the subject image. There is. Image retention templates used for such purposes are
For example, it is disclosed in USP-4,268,144 (Wheeler) or USP-4,816,848 (Doyle).

Wheeler's template uses a flexible, relatively thin film and has a structure with protruding ears on three sides for insertion into the frame of the exposure window.

Further, in order to prevent the template from being pulled out together with the film on the lower surface of the template when it is pulled out to one side, a single claw is provided outside the surface of the template. Since Wheeler's template has the structure outlined above, it is not very easy to mount it inside the window frame from outside the exposure window. Further, when the image holding surface is worn, the user's fingers are likely to touch the image holding surface and cause damage or fingerprints. Furthermore, since there is plenty of space under the window frame into which the template ears are inserted, and the width of the above-mentioned claws is relatively narrow, when the exposed film unit is pulled out from the film pack container, other In some cases, the relative position or direction between the template and the exposure window tends to shift.

On the other hand, Doyle's template 10 shown in FIG. In order to prevent the exposure window from being pulled out, a pair of stop members 38.40 are provided in parallel on the sheet 36 in contact with the front and rear frames 24.26 of the exposure window.

Since the width of the template 10 between them is the same as or slightly narrower than the opening width of the exposure window, the flexibility of the sheet 36 can be used to easily attach and detach it. Further, the relative positional relationship of the template 10 with respect to the exposure window is
As defined by the book stopper 38° 40, the exposed film unit 16 is removed from the film pack container 12.
When the bow 1 is pulled out, the relative position or direction of the template 10 and the exposure window does not shift, resulting in good stability.

Therefore, it is easy to handle and overcomes the drawbacks of Wheeler's template.

(Problem to be Solved by the Invention) However, in Doyle's template, the distance between the two sets of stop members is too wide relative to the dimensions of the exposure window, and the template cannot be set in the exposure window. In this case, the sheet surface may be curved and lifted from the film surface, and therefore, considerable attention must be paid to the spacing when attaching the stopper member. Needless to say, it is desirable that the number of steps involved in attaching the stopper member to the template is small.

The present invention aims to solve these problems using Doyle's template as a starting point, and to provide a further improved template.

(Means for Solving the Problems) In order to solve the above problems, the image holding template of the present invention has a substantially rectangular exposure window, accommodates a plurality of film units in a stacked manner, and A film pack container whose uppermost film unit is moved in the direction of movement along one side of the exposure window and placed outside, which is equal to or slightly shorter than the dimension of the exposure window in the direction perpendicular to the movement direction. It has a first side and a second side that is longer than the exposure window dimension in the moving direction, and the maximum dimension in the same direction is equal to or shorter than the internal dimension of the film pack container in the same direction, and has an almost rectangular shape as a whole. A thin sheet and the window frame of the exposure window on the side facing the moving film unit, with this sheet attached to the film pack container so as to evenly cover the film surface of the top film unit. At least two protrusions (front protrusions) protruding outside the seat surface are provided at symmetrical positions with respect to the center line of the seat extending in the moving direction on the tangent between the edge of the front window frame and the seat. Features. In addition to the above-mentioned front projections, at least one similar projection (lateral projection) may also be provided on each side of the sheet along the two side window frames that intersect with the front window frame. .

These protrusions may be formed integrally with the sheet by deforming the template sheet itself, or by attaching a member (stopping member) separate from the sheet to the sheet surface so that the stopper , at least some of these protrusions may play a role.

(Function) In order to attach the image holding template according to the present invention to the exposure window of a film pack container, the sides of the template and sheet in a direction perpendicular to the first side are bent, and both ends of the sheet in that direction are exposed. It is easy to install as it just needs to be inserted into the frame work at the front and back of the window. At that time, make sure that the protrusion or stopper member on the sheet is on the front window frame side of the exposure window. When the attachment of the template is completed in this way, the protrusion or stopper member on the sheet engages with the front window frame of the exposure window,
It is possible to prevent the template from being pulled out together with the exposed film unit when the exposed film unit is pulled out. especially,
Since the front projections are arranged symmetrically with respect to the center line extending in the direction of movement of the sheet, the posture of the template is maintained stably even when the film unit is pulled out.

In addition, when similar protrusions are provided on each second side of the sheet along the two side window frames that intersect with the front window frame, or when the stop member has a shape that makes effective contact with the side window frames, Since these protrusions or members fit tightly into the area surrounded by the front window frame and side window frame of the exposure window, the template can stably maintain the correct orientation with respect to the exposure window, and its The position and direction will not shift.

(Examples) Hereinafter, some examples of the present invention will be described with reference to the drawings. Note that the same reference numerals are used for parts common to the conventional example shown in FIG.

FIG. 1 is a perspective view showing an example image-retaining template together with a conventional film pack container. In the figure, 10 is an image holding template, 12 is a film pack container, 16 is a film unit housed in the film pack container 12, and a frame 34 is provided at the end of the film pack container 12 for pulling out the exposed film unit 16. It shows the aperture that was opened. The template 10 includes a sheet 36 and protrusions 60 to 6 provided on the sheet surface.
It consists of 5. - the thin sheets 36 have a first side that is equal to or slightly shorter than the lateral dimension of the exposure window of the film pack container 12 and a second side that has a length that is greater than the longitudinal dimension of the exposure window; The sheet has a rectangular shape as a whole, including the case where the corners of the sheet are cut diagonally as shown in the figure for convenience of handling. A portion between both ends of the sheet in the second side direction and 46 is inserted under the front window frame 24 of the exposure window and the rear window frame 26 opposite thereto. This sheet is preferably made of a transparent and flexible material.

(a), (b), and (c) of FIG. 1 each show templates 10 as three embodiments of the present invention. Each template has two forward protrusions 60 projecting out of the plane at symmetrical positions with respect to the centerline on its plane.

(a) is an example in which protrusions are provided at positions that engage with both corners where the front window frame and the side window frames intersect, and the protrusions in (b) engage only with the front window frame. In (c), in addition to the two front projections 60, there is one side projection 65 on each second side, and in addition to the engagement mode shown in (b), it also engages with the side window frame. All of these protrusions are formed integrally with the seat 36 by deforming the sheet 36 itself, but they may have any appropriate shape such as a triangular bell shape or a divided spherical shell shape.

FIG. 2 shows a template 10 corresponding to that shown in FIG. 1(b) above (however, the shape of the protrusion is a triangular bell shape) is attached to the film pack container 12, and the protrusion 60 is engaged with the front window frame 24. FIG. 3(b) is a partial sectional view taken along the arrow line 2-2. Note that FIG. 5B shows a spring 50 that is inside the film pack container and pushes up the film unit.

FIG. 3 shows two further embodiments in addition to those shown in FIG. 1 above. In all of the examples listed here, a single stopper member 70 separate from the seat 36 is attached to the seat to produce the same effect as the protrusions 60 to 65 shown in FIG. 1. Note that it is also possible to replace only the front projection 60 with the stop member 70 and combine both with the projections 65 on the sides.

FIG. 3(a) shows an elongated rectangular stop member 70 and a side protrusion 6.
(b) shows an example in which a single stopper member formed in a U-shaped planar shape with a long middle side is used. On both sides, the length of the stopper member 70 in the longitudinal direction (
In the case of (b), it is effective to make the outer dimension (external dimension) equal to the dimension a of the first side of the sheet 36 in order to prevent the sheet from shifting laterally.

FIG. 4(a) is a plan view showing a state in which the template 10 corresponding to the one in FIG. 3(b) is attached to the film pack container 12 and the stopper member 70 is engaged with the front window frame 24; Figure (b) is a partial cross-sectional view at the position of arrow 4-4. Although the cross-sectional shape of the stopper member 70 appears as a rectangle in FIG. It goes without saying that an appropriate cross-sectional shape can be used, such as one that rises vertically from the top.

Next, the operation of each of the above embodiments will be explained.

Image retention template 10 is placed in film pack container 1
To attach to the second exposure window of the template 10,
Flex the sides and use Template 10 between both ears.

46 under the frames 24 and 26 at the front and rear of the exposure window. Then, the lower surface of the sheet 36 of the template 10 comes into close contact with the photosensitive surface of the film unit 16. that time,
The front projection 60 or stopper member 70 on the sheet is placed on the side where the front window frame of the exposure window is located.

When the mounting is thus completed, the front projection 60 or the stop member 70 engages with the front window frame of the exposure window, thereby preventing the template 10 from being pulled out together with the exposed film unit 16. In particular, the anterior protrusion 6
Since the template 10 is arranged symmetrically with respect to the center line extending in the direction of movement of the sheet, the posture of the template 10 is maintained stably even when the film unit is pulled out. In addition, when the side protrusions 65 are provided, or when both ends of the stopper member 70 in the longitudinal direction effectively contact the side window frame of the exposure window, these protrusions or members are attached to the front window frame and side of the exposure window. Since the template 10 is tightly fitted into the area surrounded by the window frame, the template 10 can easily maintain the correct orientation with respect to the exposure window, and its position and orientation will not shift.

(Effects of the Invention) Since the image holding template according to the present invention is configured as detailed above, the second side thereof is bent and attached to the film pack container so as to be in close contact with the photosensitive surface of the film unit. It is extremely easy to do this, and the images on the template are less likely to be stained or damaged. In addition, since the protrusions or stop members effectively engage with the front and side window frames of the exposure window of the film pack container, the template can be stably maintained in the correct direction with respect to the exposure window, and the exposed The position and direction of the template will not shift even when the film unit is pulled out from the film pack container.

Furthermore, in the image retention template according to the present invention,
It is sufficient to deform the sheet itself to form protrusions or attach one stopper to the sheet, so the requirements for dimensional accuracy are more relaxed compared to the conventional example of two stoppers. In addition, the number of man-hours required for installation is reduced.
