b is surely separated from the spacer 39. As a result, only the spacer 39 is sucked into the double nozzle 322.
Although the suction mechanism and the blow mechanism are operated at the same time, the blow mechanism may be operated before the suction mechanism is operated, or vice versa. In the case of a spacer which is not also used as a diaphragm, air may be jetted to the rear lens 37b through an exposure opening for passing subject light toward the film.

The front lens 37a and the rear lens 37b separated from the exposure unit 19 are conveyed and collected by collection conveyors 191 and 192, respectively, and reused after appearance inspection and cleaning. Lens holder 38 and spacer 3
9 are each converted into a raw material and recycled.

Thereafter, the main body base 18 to which the exposure unit 19 is attached is removed from the rear cover 23 at the twentieth stage 194. The removed main body base 18 is
The shutter button 13 is moved from the exposure unit 19 to the collection conveyor 196,
8, the light guide 11 and the winding knob 14 are respectively removed. The main body base 18 from which these are removed is
The exposure unit 19 and the light-shielding lid closing mechanism are reused after the function test.

In the twenty-second stage 200, the rear cover 23 is inspected for contamination by imaging and image processing. And
In the 23rd stage 201, the rear cover 23 is removed from the pallet 102, and is collected in the collection box. The rear cover 23 is crushed and pelletized while a part of the main body label 78 is adhered, and is recycled as a new raw material of the rear cover 23. 24th stage 202
Then, dust, dust and the like on the pallet 102 are sucked by the dust collector, and the pallet 102 is cleaned.

FIG. 30 shows another embodiment of the lens disassembling mechanism. This lens separation mechanism is disposed after the lens holding mechanism 302. This mechanism uses a cover 550 provided at the end of an up-and-down type hose 549 to receive the cylinder 36.
And the outer circumference thereof is covered, and the air is blown into the receiving cylinder 36 through the hose 549. At this time, the front lens 3
Cover 5 so that 7a is not blown out of receiving cylinder 36.
The front lens 37a is pressed by a pressing portion 551 provided on the inner wall of the lens 50. The pressing portion 551 is formed by projecting the inner wall of the cover 550 toward the inside.

When the pressing is performed by the pressing portion 551, the pressing is performed at such a strength that there is a gap between the front lens 37a, the spacer 39, and the rear lens 37b, into which the charging air enters. As a result, the front lens 37a, the spacer 39, and the rear lens 37b are gradually charged, and can be reliably prevented from adhering due to static electricity. After that, it is only necessary to individually hold and separate from the receiving cylinder 36 using the above-described holding means such as the suction nozzle. In addition, as a means for holding down, a restricting portion for restricting the front lens 37a from dropping may be provided inside the cover 550 and at a position where a gap is provided so as not to drop the front lens 37a from the receiving cylinder 36. According to this, since it is not necessary to directly press the front lens 37a, the static elimination air can reliably enter the gap between the front lens 37a, the spacer 39, and the rear lens 37b.

FIG. 31 shows the cover 550 and the front lens 37a.
A gap is provided between the front lens 37a, the spacer 39, and the rear lens
7b is an example in which it is inserted into the mutual gap.
On the inner periphery of the cover 550, a step portion 560 that is recessed by one step is formed. The cover 550 is provided between the step portion 560 and the flange portion upper surface 37c of the front lens 37a.
When a is floated by the static elimination air, it is set at a position where only the flange portion comes into contact and a gap is formed to such an extent that the posture does not change. As the front lens 37 c floats, the static elimination air is efficiently supplied to the spacer 39 and the rear lens 3.
7b. Further, the cover 550 has a gap such that the step portion 560 is in contact with the upper surface 36a of the receiving cylinder 36 or the front lens 37a does not fall off the receiving cylinder 36. The gap between the step portion 560 and the receiving cylinder upper surface 36a may be partially provided.

As another method of the lens separating mechanism, the spacer 39 or the rear lens 3 attached to the front lens 37a or the spacer 39 sucked by the suction nozzle using a scraping plate is used.
7b may be brought into contact with the edge of the scraping plate to separate it.

In the above embodiment, a film unit having a lens cover has been described as an example. However, the disassembling method and apparatus of the present invention can be applied to disassembling a film unit having no lens cover. . Further, although the lens is disassembled while the exposure unit is attached to the main body base, the present invention is not limited to this, and the lens may be disassembled from the exposure unit detached from the main body base.

In the above embodiment, the lens holder is used as the pressing member. However, the present invention is not limited to this, and the lens cover may be a front cover for sandwiching the taking lens and the spacer between the main body and the base. In this case, the lens holding-off step can be omitted.

[0099]

As described above, in the present invention, a double nozzle of an inner tube and an outer tube is used, the outer tube sucks and separates the spacer, and the air jetted from the inner tube is used for the spacer. Since the rear lens is prevented from sticking to the spacer by spraying toward the rear lens through the exposure opening, only the spacer can be reliably separated from the main body base. According to another aspect of the invention, the spacer attached to the front lens is removed by suction when the front lens is separated, so that the spacer and the eye lens can be reliably prevented from being mixed with each other. It is possible to reliably prevent the spacer from dropping on the way to cause a mechanical trouble or the like. Furthermore, in another invention, static electricity is removed by blowing static elimination air, so that it is effective in the case of adhesion by static electricity.
