DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a method for loading a film into a film unit with a lens will be described in detail with reference to FIGS.

FIG. 1 is a perspective view showing a state before the cartridge and the spool are loaded into the unit main body. The process of loading the cartridge and the spool into the unit main body will be described with reference to FIG.

In FIG. 1, 1 is a unit body,
Although various photographing mechanisms are mounted, descriptions of mechanisms unrelated to the present invention are omitted. Reference numeral 2 denotes a front cover that covers the front surface of the unit body. Reference numeral C denotes an APS film cartridge, which contains all unexposed films including the leading end. Reference numeral 3 denotes a spool as a winding member, which winds the film around a side wall 3b between the flanges 3a. As will be described later in detail, an intake hole 3c as an attachment portion for attaching a film to the side wall 3b is formed, and a hollow hole 3d is provided in the axial direction.

As described above, in the first step, the unit main body 1 with the front cover 2 mounted thereon, the cartridge C, and the spool 3 are prepared, the cartridge C is loaded into the cartridge chamber 1a of the unit main body 1, and the spool 3 is mounted in the unit. The film is loaded into the film roll chamber 1b of the main body 1.

The cartridge C is inserted into the cartridge chamber 1
a, the film winding shaft C1 on the surface side hidden in the axial direction of the cartridge C is engaged with the winding shaft 12 directly connected to the winding knob 11, and the light shielding cover on the surface side similarly hidden. The shaft C2 is engaged with the light-shielding cover opening / closing shaft 13. As is well known, the APS film cartridge has a built-in light-shielding lid at the film entrance and exit, and the film entrance is normally closed by the light-shielding lid to prevent exposure of the film inside. The light-shielding cover shaft C2 is formed integrally with the light-shielding cover.

The spool 3 is provided with an intake hole 3c in the side wall 3b.
Is placed directly above.

As described above, the cartridge C and the spool 3
After the unit body 1 has been loaded,
And light shielding the film.

Next, in the step of feeding the film from the cartridge C, it is necessary to open the light shielding cover of the cartridge C and the winding shaft 12 must be rotatable at least in the film feeding direction. These working steps will be described with reference to FIG. 2, which is a perspective view of one embodiment of a winding mechanism including a shutter charge.

In FIG. 1, the hoisting knob 11 is formed integrally with the hoisting shaft 12, and the hoisting knob 11 is prevented from rotating in the clockwise direction, which is the direction opposite to the hoisting direction, by a reverse rotation preventing claw 14. Therefore, the tip of the reverse rotation preventing claw 14 is pushed clockwise by the rod-shaped jig to release the engagement between the reverse rotation preventing claw 14 and the winding knob 11. Further, the light-shielding cover opening / closing shaft 13 protrudes upward from the cartridge chamber 1a through the unit main body 1. When the light-shielding cover opening / closing shaft 13 is rotated clockwise by a jig, the light-shielding cover shaft C2 of the cartridge C is also clocked. The light-shielding lid inside is opened.

A jig for operating the reverse rotation preventing claw 14 and a jig for rotating the light shielding cover opening / closing shaft 13 are inserted through holes (not shown) formed in the front cover 2.
These holes are finally covered with a paper cover or the like, and do not appear in appearance.

An image frame 1c for forming a photographing screen is provided between the cartridge chamber 1a and the film roll chamber 1b in the unit main body 1. A perforation Fa of the film F is provided near the image frame 1c. An engaging sprocket 15 is provided. The sprocket 15 rotates with the feeding of one frame of the film F, performs shutter charging and indexer feeding, and also controls the rotation of the winding knob by an interlocking mechanism. Therefore, the film F meshes with the sprocket 15, and further the film roll chamber 1b
It is desirable that the sprocket 15 be rotatable at least in the feeding direction of the film F in order to feed the spool F to the spool 3 without resistance.

FIG. 3 is a longitudinal sectional view of a film unit with a lens. 2 and 3, the sprocket 15
Is fitted to a shaft 16a below the charge cam 16 for performing shutter charge, and integrally rotates. The shaft 16b above the charge cam 16 has a through hole 2 at the front end of the front cover 2.
a. Therefore, if a jig is inserted through the through hole 4a formed in the rear cover 4 and is moved upward while sandwiching the shaft 16b above the charge cam 16, the lower shaft 16
The engagement between a and the sprocket 15 is released, and the sprocket 15 becomes rotatable.

Since the sprocket 15 of the present embodiment rotates ３ by feeding one frame of the film F, the shaft 1
If the cross-sectional shape of 6a is triangular and the sprocket 15 is fitted with a triangular hole, the phase of the cam does not shift due to attachment and detachment.

Further, the through hole 2a of the front cover 2 and the through hole 4a of the rear cover 4 are finally covered with a paper cover or the like, and do not appear in appearance.

As described above, after the step of opening the light shielding cover and making the winding knob 11 and the sprocket 15 rotatable,
The film F is sent out from the cartridge C and the spool 3
The following steps will be described with reference to FIG. FIG. 4 is a perspective view of a state in which the film is sent out and the film is wound up, but the rear cover 4 is omitted for the sake of explanation.

In FIG. 4, reference numeral 21 denotes a delivery motor which comprises a servomotor and delivers a film, and rotates a film feed shaft 23 via a clutch 22. When feeding out the film F from the cartridge C, the film feed shaft 23 is engaged with the film winding shaft C1 of the cartridge C, and the film winding shaft C1 is rotated counterclockwise.

The rotation of the film feed motor 21 may be transmitted to the winding knob 11, and the film F may be fed from the cartridge C by rotating the winding knob 11 in the reverse direction.

Here, the leading end of the film F is
Before being sent to the position of the intake hole 3c above the
The distal end of the vacuum head 25 connected to the vacuum pump 24 is in close contact with the hollow hole 3d of the spool 3. The operation in this state will be described with reference to the sectional view of FIG.

4 and 5, the vacuum head 25 is brought into close contact with the hollow hole 3d of the spool 3. Then, the air is suctioned by the vacuum pump 24. Then, the air is sucked from the suction hole 3c through the vacuum head 25 and the hollow hole 3d, and the leading end of the film F is sucked to the side wall 3b of the spool 3. In addition, 26
Is an O-ring, which prevents unnecessary intake from being performed through a gap between the vacuum head 25 and the hollow hole 3d.

As described above, the film F is sent out from the cartridge C while the air is sucked from the hollow hole 3d of the spool 3 using the vacuum pump 24. When the leading end of the film F is fed out to the position of the intake hole 3c of the spool 3, the intake hole 3c is closed by the film F. Therefore, a pressure sensor (not shown) attached to the vacuum pump 24 This state can be detected, and as a result, the rotation of the delivery motor 21 is stopped. In this case, the film feed shaft 23 may be idled via the clutch 22 while the film feed shaft 23 is kept engaged with the film winding shaft C1 of the cartridge C, or the feed motor 21 is retracted in the axial direction. Then, the engagement between the film feed shaft 23 and the film winding shaft C1 may be released.

Next, in a state where the leading end of the film F is attracted to the side wall 3b of the spool 3, the winding motor 27 composed of a servo motor is driven. Then, the winding motor 2
The first gear 28 connected to the shaft 7 rotates clockwise, and the second gear 29 meshing with the first gear 28 rotates counterclockwise. Since the second gear 29 is formed integrally with the vacuum head 25, the vacuum head 25 also rotates counterclockwise, but the projection 25a provided at the tip of the vacuum head 25 has a notch 3e provided on the spool 3. , The spool 3 is rotated counterclockwise while the film F is being sucked. After the film F has been wound around the spool 3 several times, the suction operation of the vacuum pump 24 is stopped.

Since the notch 3e provided on the spool 3 is provided in the same direction as the intake hole 3c in the radiation direction, the position of the intake hole 3c can be determined even when the rear cover 4 is mounted.

Thereafter, since the length of the film F is known in advance, the film F is wound up while detecting the number of rotations of the winding motor 27, and the first frame to be photographed is one frame longer than the picture frame 1c. When it is located on the spool 3 side, the winding motor 27 is stopped. In this way, the winding step ends.

Further, since two flanges 3a are provided on the side wall 3b of the spool 3, there is no possibility that the film F is displaced in the axial direction to cause so-called bamboo winding.

In the above description, the rear cover 4 is mounted after the step of loading the cartridge C and the spool 3 into the unit main body 1. However, after the film F is wound on the spool 3, the rear cover 4 is mounted. May be attached. However, in the former case, the film can be wound in a bright room, whereas in the latter case, the film needs to be wound in a dark room.

Next, a manufacturing method slightly different from the above-described manufacturing method will be described.

First, in the above-described manufacturing method, the film F is adhered to the spool 3 by suctioning through the suction hole 3c provided in the spool 3 using the vacuum pump 24. As shown, an adhesive layer 31 may be provided as an attachment portion on a part of the side wall 3b of the spool 3, and the leading end of the film F may be attached to the adhesive layer 31. In this case, suction by the vacuum pump 24 is unnecessary, and it is sufficient that only the film winding by the winding motor 27 is possible.

As shown in FIG. 7, the side wall 3b of the spool 3
An adhesive layer 32 may be provided on the entire periphery of the substrate as an attachment portion. In this case, the suction by the vacuum pump 24 is, of course, unnecessary, and the position of the adhering part is not required. Further, the spool 3 does not need to be kept stationary, and may be kept rotating.

At this time, it is desirable to rotate the spool 3 at a speed equal to or lower than the feeding speed of the film F.

6 and 7, after the film F has been wound on the spool 3, the cartridge C
Since the load on the delivery motor 21 decreases, the delivery motor 21 may be stopped by detecting this.

In forming the adhesive layers 31 and 32,
It is desirable to use a double-sided tape.

Further, regarding the loading of the cartridge C,
Other methods are also conceivable. That is, in the above-described method, the cartridge C is loaded into the cartridge chamber 1a of the unit main body 1 before the film F is sent out, but only the film F is sent out of the unit main body 1 and the film F is sent out. The cartridge C and the spool 3 may be loaded in the unit body 1.

FIG. 8 shows another loading method of the cartridge C. In FIG. 8, first, the film F is fed out of the cartridge C outside the unit main body 1. The above-mentioned delivery motor 21 is used for this delivery. Further, the length of feeding the film F is equivalent to a length in which the cartridge C and the spool 3 are loaded into the unit main body 1 and the leading end of the film F sent from the cartridge C reaches the intake hole 3c of the spool 3. Thereafter, the spool 3 is loaded into the film roll chamber 1b of the unit main body 1, and subsequently, the engagement between the cartridge C and the delivery motor 21 is released.
Is loaded into the cartridge chamber 1a. Thereafter, as described above, the suction of the film F to the spool 3 by the vacuum pump 24, the winding of the film F to the spool 3, and the stop are performed.

It should be noted that the above-described adhesive layer 3
1, 32 may be used.

The rear cover 4 may be mounted immediately after the spool 3 and the cartridge C are loaded in the unit main body 1 or after the winding of the film F on the spool 3 is completed.

In the above-described embodiment, the film F is wound around the spool 3 as a single product.
The film F may be wound around a take-up shaft attached to the end of No. 5, and after winding to a predetermined length, the take-up shaft may be pulled out and shipped with a film roll without a core. Accordingly, the winding member in the claims includes both the spool 3 and the winding shaft.

Although the above embodiment has been described with reference to an APS film having no perforation at the leading end of the film, the present invention can be applied to a 135 film having perforation at the leading end.
