Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a loading auxiliary device for loading a sheet film into a film holder in a camera.

[0002]

[Prior art]

 Conventionally, when taking a photograph with a sheet film, an unused film must be loaded in the film holder.

As shown in FIG. 5, the method of loading the film is to slide the light-shielding lid 11 provided on the film holder 10 and invert the flap 12 to insert an unused film 40 into the film holder 10. To do. After the film is inserted, the flap 12 is returned to its original state, the lid 11 is slid and inserted into the recess 13 of the flap 12, and the film loading is completed.

[0004]

[Problems to be solved by the present invention]

 However, the flap installed in the film holder tries to return to its original position when it is turned over, so it was necessary to hold the flap with the finger at all times while the film was being inserted. Therefore, the usual loading method was to hold the flap backward with one hand while inserting the film with the other hand. However, the operation of inserting the film with one hand caused many problems due to the difficulty of work and the loading time.

In view of the above points, the present invention provides a sheet film loading auxiliary device that can be loaded easily and in a short time when loading a sheet film into a film holder.

[0006]

Means for Solving the Problems To achieve the above object, a sheet film loading auxiliary device of the present invention comprises a rectangular body, an insertion portion of a film holder, and a locking portion having a locking side, A pair of guides were installed, a groove was formed in the floor of the main body, and a plurality of anti-slip members were fixed to the bottom.

A film mounting table is detachably installed on both side surfaces of the main body.

Also, the locking portion installed on the main body is made slidable.

[0009]

[Action]

 The operation and operation of the present invention will be described with reference to the drawings. (1) Slide the light shielding lid 11 provided on the film holder 10 to invert the flap 12. (2) Fit the recessed portion 13 of the inverted flap 12 and the locking side 5 installed in the main body 1. (3) Insert the unused film 40 into the film holder 10. (4) After the film is inserted, the film holder 10 is slid to release the fitting between the flap 12 and the locking side 5 to return it to the original state, and the lid 11 is slid to be inserted into the recess 13 of the flap 12. .

【Example】

 Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

Reference numeral 1 denotes a main body of a rectangular loading auxiliary device made of a hard member, and the entire surface of the main body 1 is colored black for antireflection. In addition, an insertion portion 2 for inserting an existing film holder 10 is provided on one side of the main body 1, and a locking portion 3 having a locking side 5 is provided on the other side facing the insertion portion 2. It is provided. Further, guide sides 4 for guiding the film holder 10 are installed in the longitudinal direction of the main body 1.

The locking side 5 installed on the locking part 3 is arranged at a position slightly higher than the guide side 4 and has a thickness that allows the locking side 5 to be inserted into the recess 13 of the flap 12 provided on the film holder 10. Consists of. The base of the locking side 5 is provided with an inclined surface 8 that contacts the inclined portion 14 of the flap 12.

In the vicinity of the insertion portion 2 on the floor 6 of the main body 1, there is formed a positioning groove 7 that fits into the projection 16 provided on the film holder 10. The groove 7 is for preventing the film holder 10 from being displaced from the main body 1 during the film loading. Further, a non-slip member 9 made of an elastic member having an uneven portion is fixed to the bottom of the main body 1.

FIG. 3 is a view showing a second embodiment of the present invention, in which a film mounting table 20 is detachably installed on both sides of the main body 1 in the longitudinal direction. The mounting table 20 has such a size that a plurality of films 40 can be mounted thereon, and convex portions 22 that fit into the concave grooves 21 of the main body 1 are provided on both side surfaces. Then, the concave groove 21 and the convex portion 22 are fitted and slid to each other so that they can be freely attached and detached.

FIG. 4 is a diagram showing a third embodiment of the present invention, in which the locking portion 3 of the main body 1 is slidable. The locking portion 3 is separable from the main body 1, a concave groove 31 is formed in the main body 1, and a locking tool 30 such as a bolt is installed at an appropriate position of the locking portion 3. When adjusting the locking part 3, the locking part 30 is loosened to move the locking part 3 to an appropriate position, and after the movement, the locking part 30 is tightened to fix the locking part 3. By adjusting by the above method, the main body 1 can be used even if the commercially available film holder 10 has a difference in size.

Next, a method of using the sheet film loading prosthesis device of the present invention will be described. The existing film holder 10 is inserted through the insertion portion 2 of the main body 1, the light shielding lid 11 provided on the film holder 10 is slid, and the flap 12 is inverted. Next, the film holder 10 is moved, and the recessed portion 13 of the inverted flap 12 is fitted into the locking side 5 provided in the locking portion 3 of the main body 1. In this state, the concave groove 7 formed in the main body 1 and the convex portion 16 provided in the film holder 10 are fitted together.

Next, after inserting the unused film 40 between the partition plate 15 and the convex side 17 of the film holder 10, the film holder 10 is slid to attach the flap 12 to the locking side 5. To release. The released flap 12 is returned to the original state, and the lid 11 is slid to insert the lid 11 into the recess 13 of the flap 12.

[0018]

[Effect of device]

 As described above, the sheet film loading auxiliary device of the present invention has the following effects by having the above-mentioned configuration.

(1) Since the flap of the film holder can be fixed with one touch, the film can be loaded easily and in a short time. (2) Since the positioning groove is formed on the floor surface of the main body, there is no risk that the film hog will shift during loading. (3) Since the non-slip member is fixed to the bottom of the main body, stable loading work can be realized.

It should be noted that if a film mounting table is installed on the side surface of the main body, work efficiency is further improved, and if the locking portion is slidable, it can be used for film holders of various sizes.
