DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for extracting a photosensitive material from a magazine for a photosensitive material, which can be loaded in a bright room by extracting a photosensitive material from a magazine outlet following a light-shielding member.

[0002]

2. Description of the Related Art There has been proposed a package in which a roll-shaped photosensitive material is wrapped with a light-shielding member, and the light-shielding member can be pulled out after being loaded in a magazine in this wrapped state (for example, Japanese Utility Model Publication No. 1-38582). Gazette).

[0003] Thus, the photosensitive material wound up in a roll shape can be smoothly drawn out from the outlet of the magazine while protecting the photosensitive material from light and moisture, and the photosensitive material can be loaded in a light room. And

In general, the loading operation of the photosensitive material is carried out in a state where the magazine is removed from the apparatus main body and the magazine is placed on a floor or a work table. The magazine mounting portion of the apparatus main body is usually the upper surface of the apparatus, and is approximately at the eye level of the operator.

For this reason, the operator lowers the magazine from the eye level, loads a new photosensitive material, attaches the photosensitive material following the light blocking member, and attaches the photosensitive material to the leading end of the photosensitive material. The reader is lifted from the magazine to correspond to the photosensitive material inlet provided on the upper surface of the apparatus main body.

[0006]

However, in the above-mentioned conventional replacement work, it is necessary to raise and lower the magazine. The weight of the magazine is about 5 kg, and the weight of the photosensitive material is about 6
kg, and as a result, the weight at the time of lifting reaches 11 kg, so that very heavy labor is required.

SUMMARY OF THE INVENTION In view of the above-mentioned facts, it is an object of the present invention to provide a method for extracting a photosensitive material from a photosensitive material magazine which does not require the operation of loading and unloading a magazine and which facilitates the loading operation of the photosensitive material. .

[0008]

According to the first aspect of the present invention, a roll-shaped photosensitive material whose peripheral surface and both end surfaces are wrapped by a light-shielding member is loaded in a magazine, and is fixed to the outermost periphery of the photosensitive material after the loading. By pulling out the peripheral side light-shielding member from the outlet, the light-shielding member is broken at the peripheral side and both end surfaces, and the photosensitive material is pulled out from the magazine outlet by following the light-shielding member. A method for extracting a photosensitive material from a photosensitive material magazine, wherein the light-shielding member is pulled out in a state where an outlet of the magazine is moved to a position off an upper surface of an apparatus main body. After the light-shielding member is separated from the photosensitive material, the magazine is moved so that the magazine outlet corresponds to the inlet provided on the upper surface of the apparatus main body.

[0009]

According to the first aspect of the present invention, when loading a new photosensitive material into the magazine, the magazine is loaded with the magazine placed on the upper surface of the apparatus main body. In this case, the light-shielding member cannot be pulled out because the outlet of the magazine faces the upper surface of the apparatus main body.

Therefore, the magazine is moved to a position off the upper surface of the apparatus main body, and the outlet is detached from the upper surface of the apparatus main body. When the light-shielding member is pulled out in this state, the light-shielding member is broken at the peripheral surface and both end surfaces, and the photosensitive material can be pulled out from the magazine outlet by following the light-shielding member. Here, for example, while maintaining the state in which the leading end of the photosensitive material is sandwiched by a pair of rollers provided on the inner side of the magazine outlet, the magazine is moved and the photosensitive material provided on the magazine outlet and the upper surface of the apparatus main body. And the corresponding entrance.

This eliminates the need to raise and lower the magazine, thereby reducing the burden on the operator and improving the workability of loading the photosensitive material into the magazine.

The magazine 32 is slidable along the rail member 78 toward the front of the apparatus. Here, when the magazine 32 is slid to the front side of the apparatus by a predetermined amount, the protrusion 7
6 serves as a stopper, and subsequent sliding is restricted.

When the magazine 32 reaches the front end on the front side of the apparatus, the outlet 68 is located at a position off the upper surface 34A of the apparatus casing 34, and the outlet 68 is exposed.

In this state, the photographic paper 30 is replaced. That is, the photographic paper 30 in the used magazine 32 is used.
The remaining members such as the reel 56 are removed and a new photographic paper 30 wrapped by the light shielding member 66 is loaded.

The operation of this embodiment will be described below. When the image frames of the negative film 12 are sequentially fed to the printing position by the negative carrier 14, the light from the light source unit 18 is transmitted, and a transmitted image is formed on the photographic paper 30. The photographic paper 30 corresponds to the frame advance of the negative film 12,
The photographic paper 30 that is sequentially pulled out from the outlet 68 of the magazine 32 and accommodated in the printing process is transported to the developing unit 36.

When the above processing is continued and the photographic paper 30 in the magazine 32 is used up, a new photographic paper 30 is
Need to be loaded into

The operation procedure from the loading of the photographic paper 30 into the magazine 32 until the photographic paper 30 is pulled out and fed into the apparatus casing 34 will be described below.

Since the periphery (peripheral surface and both end surfaces) of the new photographic paper 30 is covered by the light shielding member 66, it can be freely carried in a bright room.

As shown in FIG. 7A, the magazine 30 placed at the normal position is slid forward along the rail member 78 without being detached from the upper surface 34A of the apparatus casing 34 (see FIG. 7A). 7 (B))). Next, the lock by the lock member 72 of the magazine 32 is released, the lid 46 is opened, and unnecessary members such as the reel 56 that has wound up the used photographic paper 30 are discarded (see FIG. 7C).

The photographic paper 30 is loaded in a predetermined position of the magazine 32 while being covered with the light shielding member 66 (see FIG. 7D). In this case, the weight of the photographic paper 30 is
Although it is about 6 kg, it is lighter by the weight of the magazine 32 (about 5 kg) than in the case where the magazine 32 is unloaded from the apparatus and loaded and returned to the upper surface of the apparatus as in the conventional loading operation. Work becomes easier.

When the loading of the photographic paper 30 is completed, the light shielding member 66 on the peripheral surface side is gripped, and the rollers 74 near the outlet 68 are held.
It is inserted into the gap and protrudes from the outlet 68 (see FIG. 7E). In this state, the lid 46 is closed and the lock member 72 is closed.
When locked, the inside of the magazine 32 is completely shielded from light and can be protected from light and moisture (FIG. 7F).

The leading end of the photographic paper 30 which has been broken at the peripheral surface side and both end surface sides and is welded in advance can be guided to the outlet 68 (see FIG. 7 (G)).

That is, even when the photographic paper 30 is loaded in a bright room, the photographic paper 30 is never exposed to light, and the loading operation is facilitated.

When the leading end of the printing paper 30 is pulled out from the outlet 68, for example, a reader is attached to the leading end, and the knob 58 is operated to rewind the printing paper 30 until the reader enters the outlet 68. At this time, the holding state by the rollers 74 provided on the inner side of the outlet 68 is maintained.

Next, as shown in FIG. 7H, the magazine 32 is slid again along the rail member 78 so that the outlet 68 and the inlet 80 on the apparatus casing 34 correspond to each other, and the knob 58 Is operated to pull out the photographic paper 30, whereby the leader can be held between the rollers 82 on the apparatus casing 34 side, and the operation of drawing the photographic paper 30 is completed.

As described above, in this embodiment, the magazine 32
The loading and unloading of the photographic paper 30 can be performed without raising and lowering the photographic paper from the upper surface of the apparatus main body, so that the operator is not forced to perform heavy labor and the workability can be improved.

In the present embodiment, the operation is performed by sliding the magazine 32 toward the front, but the magazine 32 may be rotated upward on the near side with the back side of the magazine 32 as the center. That is, if the outlet 68 is moved so as to be exposed, the operation of raising and lowering the magazine 32 can be omitted.
