3 is a film guide combined with the film sending roller; 4 is a film guide that unwinds the tongue of the film and creates a trigger for the tongue to come out. Film tip peeling members 5A and 5B are film guides for guiding the fed film.

Further, 6 is a detector consisting of a light emitter 6A and a light receiver 683- for detecting the leading edge of the film that has been sent out, and 7A is a driven roller that fills the detector 6.

FIG. 2 is a plan view of the film handling device shown in FIG. 1. -1; Film feed roller 2A.

As shown in FIG. 2, 2B is provided in a shape that is combined with the notch of the film guide 3, and 1 is designed to prevent the film F wound around the spool L from loosening by a drive means (not shown). It is configured to be able to reciprocate between a position where it contacts this and a position where it separates therefrom. The film feeding rollers 2A, 2B and the film guide 3 move the film F at the position shown by arrow A.
The spool 1 receives the spool 1 wound therein and moves to the position indicated by arrow B.

The front ID film tip peeling member 4 is configured to be able to reciprocate in the direction of arrow C, and is biased toward the spool 1 around which the film F is wound by a spring (not shown). In addition, since the film tip peeling member 4 comes into sliding contact with the film F,
It is made of a material with good sliding properties and good conductivity, such as stainless steel, and has a wedge-shaped structure as shown in FIG. Plane portions 4A and 4B of the wedge-shaped film tip peeling member 4
It is desirable that the angle α formed by the two is about 20 to 35 degrees, and particularly preferably about 25 degrees. Further, the side 4c of the wedge-shaped film tip peeling member 4 that contacts the film F has an arc-shaped cross section, and the size of this arc is such that the film F is a 12-shot film with the smallest winding diameter. , to the case of a 36-exposure film with the largest winding diameter, it is sufficient that the end of the circular arc comes into pressure contact with the film and has a dimension that allows appropriate tongue extension.In this embodiment, the radius is 6. 5 It has turned into pus.

In addition, in the film handling device shown in FIGS. 1 and 2, the distance #L between the spool 1 and the nip roller pair 7 is:
In order to reduce damage to the film F due to sliding contact with the film tip peeling member 4, the feeding angle of the film F should be shortened by 5 as much as possible within a range that does not become too steep with respect to the traveling direction of the film F. In this embodiment, the length is preferably about 65++n+, which corresponds to the outermost roll 6) of the film wound on the spool 1.

The operation of this embodiment configured as described above will be explained below.

Inside the film feed rollers 2A, 2B and the film guide 3, which are waiting at the position indicated by the arrow A above, there is a spool wound with the film F taken out from the cassette in the previous process, which is the process of taking out the film from the cassette. When the film is fed in, the film feed roller 2
A, 2B and the film guide 3 move to the position indicated by the arrow B while holding the spool I wound with the film. In this state, the film feed rollers 2A, 2B and the film tip peeling member 4 are lightly pressed against the surface of the film F.]
I'm here. Here, the film feeding rollers 2A and 2B are driven in the direction of feeding out the film F based on the information regarding the forward and reverse direction of the film winding direction detected in advance in the previous process, and then the film leading end peeling member 4 is driven.

When the tongue passes between the pair of nip rollers 7A and 7B and is detected by the detector 6, the nip roller 7A moves to the position shown by 7C and performs operations such as nipping the film F and sending it to the next process. At this point, the film feed rollers 2A, 2B holding the spool 1 and the film guide 3 have retreated to the position indicated by the arrow A,
The film F to be sent out is prevented from sliding against the film tip peeling member 4 and being damaged.

In the above-mentioned film feeding operation, air is blown from air blowing nozzles provided at the rear side in the film feeding direction, for example, at the positions indicated by arrows and E in the figure, based on the information regarding the forward and reverse directions of the film winding direction. By blowing out and creating negative pressure on the outer peripheral surface of the film F,
7- It becomes possible to perform the tongue extension operation more smoothly and stably. Upper penetrating air blowing is particularly effective when the film removed from the cartridge has strong curls.

In the above embodiments, the film feeding rollers 2A and 2B combined with the film guide 3 are shown as film feeding means, but this may be replaced by other means, such as a narrow belt combined with the film guide 3. Needless to say, it is possible. Further, in the above embodiment, the film/feeding rollers 2A, 2B and the film guide 3 receive the film taken out from the cartridge at the position indicated by the arrow A, and move to the film feeding position indicated by the arrow B. I showed an example, but this is
As will be described later, it goes without saying that a mechanism for taking out the film from the cartridge may also be moved.

Hereinafter, regarding the film 8-holding device described in -H above, the mechanism for taking out the film from the cartridge and the mechanism for holding the spool wound with the taken-out film are integrally moved to the film feeding position. explain.

FIG. 4 is a front view showing the main parts of a mechanism for taking out a film from a cartridge, and FIG. 5 is a sectional view taken along line GG. FIG. 4 shows a situation in which the film fed out from the disassembled cartridge is delivered to the film holding means together with the spool.

In the figure, 8 is a cartridge held by a holding means (not shown), 9 is a rotating shaft that holds one end of the spool l on which the film F is wound and transmits rotation thereto, and 10 is a cartridge after disassembling the cartridge 8. A shaft movable in pair with the rotating shaft 9 for taking out the film F; 11 is a film receiving section; 12A and 12B are film guide members whose positions can be changed as will be described later; 13 is a This is a detector consisting of a light emitter 13A and a light receiver 13B.

As shown in FIG. 4, the film receiving section 11 has a first opening through which the rotating shaft 9 is inserted and a second opening through which the film is received. As shown in FIG. 5, there is a film receiving section 11A that receives the spool 1 pushed out from the spool 1 together with the film F wound therein, and a film receiving section 11A that is capable of suppressing the film received in the film receiving section 11A and as shown in FIG. A film holding member 11 made of a material with high frictional resistance such as urethane rubber and configured to be removable to the fourth part 11B provided in the part 11A.

Once housed in the spool 1A, the spool 1 is configured to be rotatable back and forth between a second position for holding one end of the spool 1.

- The reciprocating rotation of the film guide members 12A and 12B is as follows:
Movement from the second position to the first position is performed by a solenoid (not shown), and movement from the first position to the second position is performed by a spring (not shown).

The operation of the present film holding device configured as described above will be explained below.

When the cartridge storing the film is set at the position shown by 8 in FIG. 4, the shaft 10 presses the spool l of the cartridge to disassemble the cartridge.
The spool l is fed out in the direction of the film receiving section 11 with the film F wound therein. Here, a detector (not shown) determines whether the fed film is front or back, and based on the result, the The rotating shaft 9 starts rotating in the direction of winding the film F at a speed of 500 to 1000 rpm+m. At this point, the film guide members 12A and 12B are in the position shown in FIG. 6, and have the function of guiding the film F sent out from the disassembled cartridge into the film receiving section 11A.

FIG. 4 shows this state, and at this point, the outer periphery of the film F is still in the film receiving section 1.
It is not completely contained within 1A. however,
By continuing to rotate the rotating shaft 9, the outer peripheral portion of the film F gradually changes from the above state to the film receiving portion 1 due to the action of the film guide members 12A and 12B.
It will be stored in 1A.

The outer periphery of the film F is completely inserted into the film receiving part 11.
When it is stored in A, the detector 13 detects this,
The excitation of the solenoid that opened the film guide members 12A and 12B is released, and the film guide member 12
A and 12B are closed by the force of the spring to hold the end of the spool 1. This ensures that subsequent operations will be performed reliably.

When the winding of the film F is completed, the film pressing member 11C, which had been moved into the recess 11B of the film receiving section 11, presses the outer circumference of the film F,
To more securely tighten a film F. At this stage, the film holding device is moved to the film feeding position W.
The film F, which has been moved to (arrow B in FIG. 1) and has been wound, is now subjected to the above-mentioned feeding process.

Furthermore, although the film guide members 12A and 12B of the film holding device shown in the above embodiments were configured to hold the spool by rotational movement, the film guide members 12A and 12
It is also possible to have a configuration in which one end of the spool is held or released by moving the spools B in the direction of enclosing each other, for example, in the vertical direction.

Note that the present invention is not limited to taking out the tongue of a photographic film wound on a spool taken out from a cartridge, but can be widely applied to the case of "taking out the tongue" of a film-like object wound on a spool. can do.
