JPH0684458U - A container with a connecting function for stereoscopic photography in a film unit with a lens - Google Patents

Abstract

(57) [Summary] [Purpose] To be able to securely connect two lens-fitted film units so that stereoscopic photography can be performed easily. Also, it is not necessary to carry the connecting device separately. [Structure] The left and right side surfaces of the lens-fitted film unit body have a surface having a concave portion and a surface having a convex portion. The two unit bodies are connected at this uneven part and cut off.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a photographic film packaging container (hereinafter referred to as "lens-equipped film unit") to which an exposure function for photographing has been added in advance.

[0002]

[Prior art]

 Conventional stereoscopic photography requires a device for connecting two cameras to another camera, and without the device, the two cameras would not be stable. In addition, it was troublesome to attach and detach the device to be connected to the two cameras, and it was inconvenient to carry the connecting device. (For example, refer to the official publication No. 98040 published in Heisei 4)

[0003]

[Problems to be solved by the device]

 The present invention has been made in view of the above problems of the prior art. The purpose of the present invention is to connect two identical film units with lenses to each other without cutting them, and to use a single unit as a normal unit. It aims to provide a connecting function to the unit body container so that stereoscopic photography can be easily performed by taking two pictures. When taking a stereoscopic picture, use one of the two viewfinders and press the respective shutter release button at the same time.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the connecting device according to the present invention forms concave and convex portions on one side of the unit body container, one concave and the other convex, and connects two unit bodies together or cuts them apart. The feature is that you can do it.

It is preferable that the concavo-convex portion has a columnar shape and four portions are provided on one surface.

The uneven portion may have a trapezoidal shape.

The uneven portion may have a key shape.

[0009]

[Action]

 According to the present invention, two unit bodies can be connected by inserting the unit body container with the concave surface and the other unit body container with the convex surface.

【Example】

 The implementation order will be described with reference to the drawings. FIG. 1 shows the external shapes of a rectangular parallelepiped unit main body 1 and a rectangular parallelepiped outer box 2 in which the unit main body 1 is housed in close contact. These are the same as the commercially available lens-equipped film “Sharp Run” (trade name).

The shaded portion 4 in FIG. 1 is the left and right side surfaces of the outer box 2, but is removed to expose the connecting surfaces 5 and 6.

In FIG. 2, two unit bodies 11 are shown side by side. These are the same. On the side surface of the unit body, the concave surface 12 has four identical concave portions 14, and on the other surface, the convex surface 13 has four identical convex portions (15). By inserting the other convex portion 15 into the concave portion 14, the concave surface 12 and the convex surface 13 are brought into close contact with each other to connect the two unit bodies.

FIG. 3 shows the cross section of the concave portion 14 and the convex portion 15. In order to strengthen the connection, the ring-shaped protrusions 16 and 17 are attached, and the protrusion 17 of the convex portion is inserted into the protrusion 16 of the concave portion.

FIG. 4 shows a schematic external appearance of a second embodiment according to the present invention. Only the structure of the connecting surface differs from that in FIG. The convex portion 22 and the concave portion 23 have a trapezoidal shape, and the convex portion 22 is vertically inserted into the concave portion 23 to connect two identical unit main bodies 21.

FIG. 5 is a cross-sectional view of the connecting portion viewed from above.

FIG. 6 shows a schematic external shape of a third embodiment according to the present invention. Only the structure of the connecting surface differs from that in FIG. The concave portion 32 and the convex portion 33 have a keyhole-key relationship. The concave portion 32 and the convex portion 33 are each an L-shaped rectangular parallelepiped.

FIG. 7 is a cross-sectional view of the connecting portion viewed from the front. (A) The concave portion 32 has the protrusion 34, and the convex portion 33 has the protrusion 35. The projections 34 and 35 have a triangular cross section, but have a triangular prism shape extending over the entire concavo-convex portion. (B) The convex portion 33 is horizontally inserted into the concave portion 32. (C) The state of being further inserted in the vertical direction. By inserting the protrusion 35 deeper than the protrusion 34, the connection is further strengthened.

[0018]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects.

Since the unit body is provided with the connecting device, it is not necessary to carry the connecting device when taking a three-dimensional photograph.

One unit with a lens can be used for ordinary photography, and two units can be connected for stereoscopic photography.

The connecting operation is simple.

By providing protrusions on the recesses and protrusions, the connection can be made more reliable.
