Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a holder for photographic photosensitive materials such as films or dry plates.

[Conventional technology]

When photographing with a large camera, information such as a serial number and an alphanumeric number for identifying the film is generally imprinted on one corner of the film at the same time. Generally, a two-digit number is often used as this identification information. For this reason, the film holder that holds the film is equipped with, for example, two rotary number dials representing each digit, and each film is identified by setting the number dials to a predetermined number and imprinting these numbers on the film at the same time. It has sex.

In conventional film holders, the numerical dial is built into the holder, and therefore, a sliding lid for preventing exposure of the film must be loaded into the holder after the numerical dial is set in advance.

[Problem that the invention attempts to solve]

Loading film into film holders is done in a darkroom after setting identification information as described above, but if the number of film holders loaded is small, it is not difficult to recognize the identity of the holders. However, in general, many films are often loaded into a holder in advance in a darkroom. In this case, if it is difficult to recognize the identity of many holders during photographing, or if one forgets, identification is no longer possible. Such a problem can be solved by writing the same information in the holder separately from the above-mentioned dial information, but then there is no point in providing the dial information means and the inconvenience cannot be avoided.
In addition, the conventional film holder has a serious drawback in that the identification information cannot be reset (changed) at the shooting site after the film is loaded. This is because the dial identification information cannot be confirmed from the outside after the film is loaded, and there is no way to operate the dial identification means from the outside. Therefore, with conventional film holders, if it is absolutely necessary to reset the identification information, the user must return to the darkroom, pull out the lid that prevents exposure of the film from the holder, reset the dial, and then replace the lid again. I had to load it inside.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the drawbacks of the prior art as described above, and to provide a film holder in which identification information can be freely confirmed and changed even after the film is loaded.

The holder of the present invention is applicable not only to sheet-like films but also to, for example, photographic dry plates, and is generally specified as a holder for photographic photosensitive materials.

[Means for solving problems]

In order to achieve the above object, the present invention provides a holder for photographic photosensitive material that holds a plate or sheet-like photographic photosensitive material together with a plate-like exposure prevention lid so that each sheet can be inserted and removed. An imprinting dial having identification information to be imprinted on the edge of the photographic photosensitive material is rotatably supported at one end of the holder main body via a rotating shaft, and the rotating shaft of the imprinting dial is attached to the holder. A holding shaft that is rotated from the outside of the main body is coaxially supported on each rotating shaft, and a fixed display board that externally displays the same identification information as the imprint dial is fixed to the holder main body. An instruction means is provided to indicate the correspondence position between the identification information on the combination dial and the identification display on the identification means on the display board, and the sliding lid is held so as to cover the photographic photosensitive material after it is loaded into the holder. A holder for photographic photosensitive material is provided, which is characterized in that it can be detachably engaged with a shaft.

〔Example〕

An embodiment of the present invention will be described based on the drawings.

FIG. 1 is a perspective view showing the entire cut film holder used for photographing with a large-sized camera. The plate-shaped sliding lid 2 is made of phenolic resin and has a handle 31, and has enough rigidity to be self-retainable. The sliding lid 2 can be slidably inserted into and removed from the holder main body 1, and an unused sheet film 3 can be inserted into and removed from the holder body 1.
is set on a core plate 33 fixed to the holder body 1, and then the sliding lid 2 is attached above the film 3. Naturally, the sliding lid 2 is removed from the holder body when photographing.

At one end of the holder body 1, that is, at the end opposite to the insertion opening of the flap 2, a flap holder (flap) 5 is rotatable (openable and closable) relative to the holder body 1 about a pivot pin 37. can be attached to. An identification display means is provided on this lid receiver 5.

For example, two (at least one) identical imprint dials 4 for imprinting identification information such as numbers onto the film 3 have large diameter heads in a recess 39 (FIG. 4) formed at the bottom of the lid holder 5. It is rotatably attached thereto via the attachment shaft 7. A hole 41 into which a shaft 7 is rotatably inserted is formed in the lid receiver 5, and the shaft 7 is inserted into the central blind hole 45 of the holding shaft 6 which is rotatably fitted into the upper stepped recess 43 of the lid receiver 5. For example, they are integrally connected to each other by press-fitting or the like. That is, the holding shaft 6 is rotatably fitted into the shaft hole 41 coaxially with the shaft 7,
The dial 4 is integrally and rotatably held by the shaft 7 and the holding shaft 6 without falling off from the lid holder 5.
A concave groove 47 is formed on the upper surface of the enlarged head 6A of the holding shaft 6, into which a tip of a rotation jig 9, which will be described later, is inserted. The holding shaft 6 constitutes an actuating means for rotating the imprint dial 4.

A concave groove 51 that opens in the insertion direction of the lid 2 is formed in the lid holder 5. On the other hand, a substantially semicircular notch 12 is formed at the tip of the sliding lid 2 to fit into the outer periphery of the shaft portion of the holding shaft 6 located in the shaft hole 41 when the sliding lid 2 is fitted into the grooves 51. This allows the sliding lid 2 to be firmly inserted deep into the holder body 1. Moreover, when the notch 12 is fitted into the holding shaft 6, the sliding lid 2 is held in a fixed position without wobbling. Each of the imprint dials 4 is in the form of a thin disk, and the numbers (“0” to “9”) to be imprinted as information are in black letters on a transparent film or transparent letters on a black film, and are arranged around the same circumference. Pictured above. The dial 4 is attached to the lid holder 5 in a mirror image position, that is, inverted vertically and horizontally so that it is in the correct position when photographing a film (FIG. 7).
The imprint dial 4 is located on the film 3, which is partially set in a fixed position so that only one predetermined number to be imprinted is photographed on the edge of the film 3, as shown in FIG.

With the above configuration, once the sliding lid 2 is set inside the holder main body 1, the numbers on the dial 4 can no longer be read.

Therefore, according to the present invention, a display board (display means) 27 (FIGS. 2 and 5) on which a fixed dial scale 8 corresponding to the dial 4 is displayed is formed on the lid receiver 5. Note that the fixed dial scale 8 may be drawn directly on the lid receiver 5. The fixed dial scale 8 is preferably arranged coaxially with the corresponding rotary transfer dial 4 .

An opening 29 is formed in the center of each dial scale 8 in the display plate 27, and the rotation jig 9 (FIG. 1) can be inserted into the upper end groove 47 of the holding shaft 6 through this opening 29.

A pointer 11 is drawn on the upper surface of the large-diameter head of the holding shaft 6 adjacent to the groove 47 (FIGS. 2 and 6). Instead of drawing the pointer 11 on the upper surface of the large-diameter head, a pointer member as a separate part may be fixed integrally.

A cutout-shaped display window 13 is formed in the lid holder 5 so that only the numbers of the dial 4 to be imprinted can be seen. In the illustrated embodiment, both of the two imprint dials 4 imprint "0" onto the film 3.

The pointer (instruction means) 11 always faces, for example, in the direction of "0", and rotates with the rotation of the holding shaft 6 and therefore with the rotation of the imprint dial 4. The numbers on the imprint dial 4 and the numbers on the fixed dial scale are reversed, and when the imprint dial 4 is turned clockwise in FIG.
The numbers "2", . . . (however, the letters are reversed) appear on the display window 13. At this time, guideline 1
1 also rotates clockwise and sequentially points to the numbers "1", "2", . . . on the fixed dial scale 8.
That is, the pointer 11 points to the same number on the fixed dial scale 8 as the number on the imprinted dial 4 visible in the display window 13.

FIG. 8 shows another embodiment of the present invention. According to this embodiment, the display plate 27 having the fixed dial scale 8 is not provided. Instead, a fixed dial scale 8 is formed directly on the upper surface of the enlarged head of the holding shaft 6. That is, on the upper surface of the enlarged head of the holding shaft 6, the same numbers as the imprint dial 4 are drawn in the same arrangement. Therefore, the holding shaft 6 is fixed to the jig 9.
When the dial is rotated as shown in FIG. 1, the number 8, which is the same as the number on the dial 4 located inside the display window 13, is always located on the opposite side of the display window 13. In this embodiment, the display window 13 serves as the pointer 11 shown in FIG. In the embodiment shown in FIG. 8, it goes without saying that a round window 34 is formed in the lid receiver 5 at a position corresponding to the enlarged head of the holding shaft 6. Note that the round window 34 may be formed by the stepped recess 43 in the first embodiment.

In the embodiment shown in FIG. 8, if the enlarged head of the holding shaft 6 is projected upward from the round lid 34, the jig 9
The holding shaft 6 can be rotated directly with a finger without using a hand.

The present invention is not limited to the above-described embodiments; for example, the display symbols are not limited to numbers as described above, but may be replaced with letters such as alpha alphabets or other signs; It is also possible to provide one or more dial scales. Further, in order to prevent relative rotation between the shaft 7 and the imprint dial 4, it is also possible to provide a rotation prevention means such as an eccentric pin and a pin hole, or a waveform surface shape.

[Effect of idea]

As described above, according to the present invention, the identification display can be confirmed from the outside even after the film is set in the holder, and the identification display can be easily changed.
