DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film unit with a lens, and more particularly to a recyclable film unit with a lens.

[0002]

2. Description of the Related Art As shown in FIGS. 3, 4, and 5, a photographing lens 5, a film winding mechanism 18, and a shutter mechanism 1 are provided.
9 in advance with the international standard IS
A unit body in which a 135 film with a patrone defined by O. 1007-1979 is housed in a light-tight manner with a rear cover 21, a strobe unit 22 is incorporated in the front of the main body, and a front cover 23 is attached from the front. There is known a film unit 2 with a lens with a flash in which an outer case 3 is covered with an outer case 4 (hereinafter, referred to as a "film unit").

The main body 2 of such a film unit 2
At 0, a film supply chamber 25 and a film take-up chamber 26 are provided on the left and right of the photographing opening 24. An unexposed film is stored in a roll supply state in the film supply chamber 25, and the user who purchased the unexposed film supplies the exposed film to the patrone main body provided in the film take-up chamber 26 for each photographing. When all the exposures have been completed, the entire film unit 2 is requested to develop at a developing dealer. At the photo lab, the patrone containing the exposed film is taken out and subjected to processing such as development and printing using the current development processing system. The user is returned with the print photograph and the film negative, which is convenient for development. Thus, the film unit 2 is not returned. Conventionally, the used film unit 2 has been destroyed and disposed of as industrial waste. However, recently, due to problems such as environmental protection and reduction of industrial waste, the film unit 2 is collected and reused for reuse. Is being considered.

[0004] In the study of this recycling, for example, a study has been made on the reuse of plastic molded parts and the like by reusing them as raw materials such as resin pellets so as not to be disposed as industrial waste as much as possible. . In consideration of such recycling, since the unit body 3 is protected by the front cover 23 and the rear cover 21, there is almost no damage such as dirt or scratches, and the photographing lens 5, the film winding mechanism 18, the shutter Since the mechanism 19 and the strobe unit 22 can be easily removed without being damaged or damaged, it has been found that it is highly valuable if the recycling can be performed without being used again.

By the way, in consideration of recycling as described above, the taking lens 5 and the film winding mechanism 1
8. Functional parts such as the shutter mechanism 19 and the strobe unit 22 must be subjected to a function test. For example, the strobe unit 22 needs to inspect the continuity of the copper foil pattern or the like printed on the printed board 22a, and needs to know the number of times of recycle in order to know the limit of the frequency of recycle use. As shown in FIGS. 6 and 7, the number of recycling times of the conventional strobe unit 22 is determined by the copper plating pattern 28 printed on the front surface of the printed circuit board 22a.
Partitions are printed on the grid in advance, and the number of black circles printed in each of the grids for each recycling can be confirmed. The black circles are printed in order from the right for each grid. Such printing has been performed by a high-precision device that recognizes a black circle mark in a grid by image processing or the like, and further recognizes a blank grid later, and then prints it with an inkjet printer or the like. With such a recycling confirmation operation, the product can be re-shipped safely and without losing the quality of the product even in consideration of recycling such as reuse as described above.

[0006]

However, the photographic lens 5, the film winding mechanism 18, the shutter mechanism 19, the strobe unit 22 and the like always have a fixed service life. This is insufficient for safety in reuse because only confirmation can be performed.

[0007] The present invention has been made in view of the above background, and has as its object to provide a film unit with a lens capable of maintaining stable quality while using recycled parts.

[0008]

According to the present invention, there is provided a film supply chamber having an opening for photographing, and a film supply chamber for accommodating an unexposed film on one side of the opening. On the other side of the main body, a film take-up chamber for winding a photographed film and a film take-up chamber are integrally formed of resin, and a photographing lens, a film winding mechanism, a shutter mechanism, a strobe board, and other components are attached. Of the parts making up the lens-fitted film unit made of recycled parts, a display indicating the production time is given to the recycled parts to be reused and a reference position is provided in advance, and when reusing the recycled parts, A mark or the like is recorded at a position apart from the reference position by a predetermined interval corresponding to the recycling time. This allows the production of recycled parts themselves
The period can be easily confirmed, the number of recycles can be known from the number of records such as marks, and the time of recycle can be easily confirmed from the recording position.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of a film unit with a lens according to the present invention is the same as that described in the prior art, and the same parts are denoted by the same reference numerals. In FIG. 2, the film unit 2
Is composed of a unit main body 3 having a photographing mechanism and an outer case 4 for housing the unit body 3, and a photograph is taken while the unit body 3 is kept in the outer case 4. The outer case 4 is for making the appearance of the film unit 2 beautiful.
A paper box or the like having an outer surface printed thereon is used. The outer case 4 includes a photographing lens 5, an objective-side finder window 6a,
There are provided holes for exposing the eyepiece side viewfinder window 6b, release button 7, number-of-photographs display plate 8, winding knob 9, and light-emitting section 10. Perform the release.

The unit main body 3 comprises a main body 20, a front cover 23, and a rear cover 21. An exposure unit 30 having a film winding mechanism 18 and a shutter mechanism 19 assembled therein and a strobe unit 22 are incorporated in the main body 20. The function of each component described above is the same as that of the component described in Japanese Patent Publication No. 2-32615, and the detailed description is omitted here.

The flash unit 22 includes a light emitting unit 1
0, a well-known X contact 31, an electrode plate 32 on which a battery is sandwiched,
33 are fixed to each other, and the printed circuit board 22a
A copper foil pattern 28 for connecting the respective contacts is printed on the front surface. As shown in FIG. 1 and FIG. 2, a display section 40 displaying the manufacturing time, the number of recycling times, and the time is provided on a main part of the front surface of the strobe substrate 22a on which the pattern 28 is printed.
Is printed in advance. The display unit 40 is printed at a predetermined position with respect to the reference position display unit 41, and is obtained by arranging grids of 5 rows and 12 columns at regular intervals. The rows in the cells indicate the year in order from the top, and the columns in the columns indicate the months in order from the left. The numbers “91”, “92”, “93”, “94”, and “95” corresponding to the year (the last two digits of the Christian era) are written beside the display unit 40. When the recycling time is represented by a season, four cells may be provided per year.

The mark of the production time and the mark of the recycling time are classified. For example, it is easy to confirm if the white circle is defined as the manufacturing time and the black circle is defined as the recycling time. Note that a mark such as a dot or an X may be used instead of the circle. For example, in the display unit 40 shown in FIG. 2, the printed circuit board was manufactured in May 1991, and was recycled in August 1992 and April 1993, and it can be confirmed that the number of recycling is two. Note that the display section 40 has five lines when the period from the first recycling time to the second recycling time is one year and the useful life of the printed circuit board is five years. If the time from the first recycling time to the second recycling time is assumed to be 2 to 3 years, the display unit 40 is set to 3 years.
And the year printed on the side of the display unit 40 is, for example, "9
1 "," 93 "," 95 ". Further, if the year of the manufacturing time shifts, and the year before the manufacturing time is read, the display unit 40 may have five rows.

Next, the above-described film unit 2
Will be described below. In the first step, the outer case 4 is removed from the collected film unit 2. The outer case 4 is recycled as used paper in the case of a paper box, for example. In the second step,
Remove the front cover 23 from the unit body 3. At this time, the winding knob 9 is removed.

In a third step, the taking lens 5 and the strobe unit 22 are removed. The taking lens 5 is detachable from the shutter cover 5a of the exposure unit 30 so that it can be easily removed, and the strobe unit 22 can also be easily removed from the main body 20. At this time, the protrusions 22b and 22c of the main body 20 and the strobe unit 22 are removed.
The engagement with the positioning holes 22b and 22c may be released. The strobe unit 22 is sent to a reassembly process after a function test. The sent strobe unit 22 has a black circle indicating the recycling time printed on a predetermined cell of the display unit 40 thereof. This printing is performed using an ink jet printer, a rubber stamp, or the like.

The printing of black circles described in the prior art has a disadvantage that expensive devices such as an image recognition device and a movement control device of an ink jet printer are required because the position is different every recycling. Display unit 4 of the present invention
When printing at 0, the printing position can be grasped in advance with respect to the reference position display section 41, so that an inexpensive printer can be used. Note that the positioning holes 22b and 22c for the main body 20 may be used instead of the reference position display section 41.

In the fourth step, the exposure unit 30 is removed from the main body 20. The exposure unit 30 is taken out without damage, sent to a reassembly process after performing a function test, and the main body 20 with the remaining rear cover 21 engaged therein stores the exposed film in the developing station. Since the extracted patrone is taken out, it is sent to the resin regeneration step as it is without any mixture of different materials. In addition, the front cover 23, the photographing lens 5, and the winding knob 9 that have been removed earlier are also sent to the resin recycling step.

Next, the reassembly process of the film unit 2 will be described. First, the exposure unit 30 that has been subjected to the function inspection from the disassembly process is attached to the main body 20. The main unit 20 to which the exposure unit 30 is attached is provided with a strobe unit 22 which has been sent to a function test from the above disassembly step and has been checked, and a front cover 23 is attached to the front of these units. Thereafter, a film with a patrone is loaded in a dark room, and then sealed with a cover 21. Finally, by covering with the outer case 4, the film unit 2 as shown in FIG. 2 is completed.

In this embodiment, the strobe unit 2
2, the display unit 40 is provided. However, the present invention is not limited to this. For example, the display unit 40 may be provided on basic components such as the exposure unit 30 and the main body unit 20 and may be applied to other cover components. . Further, in practicing the present invention, the display unit 40 including a number representing an era and a frame line is not necessarily required. That is, a reference position display is provided in advance at a certain reference position at the time of manufacture of a part to be recycled,
A mark or the like may be printed at a position separated by a predetermined interval from the reference position display according to the time of recycling. The number of reading and recycling of these marks,
The timing can be confirmed by photoelectric or mechanical automatic reading in addition to visual observation. In addition, as the reference position display, for example, a hole or a projection serving as a positioning reference when incorporating a recycled component can be used instead.
