Description

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 using a brownie film.

[0002]

2. Description of the Related Art A simple exposure mechanism is provided so that anyone can easily enjoy photographing, and an unexposed photographic film and a patrone are pre-loaded at the time of manufacture, eliminating the need for cumbersome film loading and film rewinding operations. A film unit with a lens, for example, "Super Photo Run" (product name) is manufactured and sold by the present applicant. Such a film unit with a lens has the international standard IS.
It is loaded with a 135 type photographic film with a cartridge (35 mm film) specified in O. 1007-1979.

On the other hand, a medium format camera using a brownie film (a common name for a roll film having a width of 6 cm) has been in widespread use mainly for a high-amateur layer for which a better image quality is required. This means that, when the screen size of the brownie film is, for example, 6 cm × 4.5 cm (actual screen size: 56 mm × 41.5 mm), the area ratio is about 2.7 times the screen size of the 35 mm film (36 mm × 24 mm). This is because the image quality does not deteriorate even in a large-sized print photograph.

[0004]

[0005] However, even if a person who knows the pleasure of taking a picture with a film unit with a lens or a compact camera and wants to take a picture with better image quality, the medium format camera is expensive and generally used. There is a drawback that handling is difficult. The biggest factor that makes this handling difficult is the loading of the brownie film. Since the brownie film is simply a band-shaped photographic film with light-shielding paper provided on the back or both ends wound around the spool, loosening may occur immediately after tearing the paper tape for stopping. If the winding loosens,
Expose light immediately. Therefore, from immediately after the paper tape is broken to the end of loading, it is necessary to carry out the loading operation while always assisting the hand so that the brownie film does not become loose. In this way, loading brownie films is a tedious task that even a trained person uses nerves, so it was not easy to purchase a medium format camera and take pictures.

SUMMARY OF THE INVENTION An object of the present invention is to provide a lens-fitted film unit that allows anyone to easily take a picture with a large screen size without having to worry about handling a brownie film.

[0006]

In order to achieve the above object, a film unit with a lens according to the present invention incorporates an exposure mechanism for exposing a photographic film through an aperture and a photographic lens disposed in front of the aperture. In a film unit with a lens in which an unexposed photographic film is pre-loaded in the unit main body, the photographic film is about
cm brownie film. In addition, the unit main body is provided with a strobe unit which is formed by mounting a strobe light emitting portion, a synchro switch, a power supply battery, a main capacitor, and the like on a circuit board on which a strobe circuit is printed and wired, and has a vertical screen size of the aperture. The strobe unit is 6 cm × 4.5 cm long in the direction, and the strobe unit is mounted above the exposure mechanism such that the longitudinal direction of the strobe light emitting unit is vertical.

[0007] A mechanism for locking the film and setting the shutter is disposed below the photographing lens as viewed from the front of the unit body, and a synchro switch of the strobe unit is disposed on the left or right side of the photographing lens. It is made to be done. Further, the photographing lens is a wide-angle single focal length lens having a focal length of 48 mm to 56 mm. Further, a finder for framing a subject is provided in the unit main body, and a display serving as a guide for focusing is provided in the field of view of the finder. Further, the display is an illustration and / or scale corresponding to the size of a subject image in a viewfinder field when a subject located at a subject distance focused by the photographing lens is viewed through the viewfinder. .

A shutter button 9 is provided on the upper surface of the rear portion 2a so as to be hidden behind the front portion 2b. Also, the unit body 2
A film counter window 10 is provided on the bottom surface of.

In FIG. 3, which shows the film unit 1 with a lens from the rear side, a winding knob 11 that is rotated in one direction every time one frame is shot is exposed at the lower right of the rear part 2a. Also, a finder 8 is provided on the back surface of the convex portion 2c.
The eyepiece 8b is exposed. The outer box 3 has an opening for exposing the shutter button 9, the film counter window 10, and the winding knob 11 to the outside.

As shown in FIG. 1, the unit body 2 includes a finder 8, a body base 12, an exposure unit 13, a strobe unit 14, a brownie film 16 with a patrone 15, a front cover 17, and a rear cover 18. Have been. The brownie film 16 is a 90 μm-thick polyethylene naphthalate (hereinafter referred to as A-A) which is annealed at a temperature slightly lower than the glass transition temperature as a base.
Brownie size using PEN (width is about 6c)
m) is a photographic film, one end of which is a patrone 1
5 is fixed to a spool 24 rotatably housed in the housing 5. Further, a well-known light-shielding telem is attached to the film entrance of the patrone 15.

On the main body 12, a patrone storage chamber 21 for storing a patrone 15 and an unexposed brownie film 16 drawn from the patrone 15 in a dark room are provided on both sides of an aperture 20 arranged on the optical axis L. A film roll storage chamber 22 for storing the film roll 16a wound in a roll shape is formed (see FIG. 6). In addition,
The screen size of the aperture 20 is long in the vertical direction, for example, 5
It is a so-called 6 cm × 4.5 cm size of 6 mm × 41.5 mm.

A circular opening 21 a is formed at the bottom of the cartridge housing chamber 21, from which the key shaft of the hoisting knob 11 is inserted and engaged with the spool 24. Also,
On the side of the circular opening 21a, a reverse rotation preventing claw 26 that engages with the knurl gear 11a of the winding knob 11 to prevent the winding knob 11 from rotating in reverse is formed integrally with the main body base 12. A long box-shaped support member 28 is formed between the aperture 20 and the patrone storage chamber 21 to vertically and vertically support an elongated rod-shaped release lever 9a integrally formed below the shutter button 9. I have. A spring 29 is stretched between the support member 28 and the shutter button 9 to urge the release lever 9a in the projecting direction. In addition, a claw 9b is formed at the tip of the release lever 9a, and the inclined surface 9c is adapted to engage with a locking lever of the exposure unit 13 described later.

The mechanical base 31 of the exposure unit 13 includes
An exposure opening 32 provided in front of the optical axis L and three shafts 33, 34, 35 provided on a lower surface perpendicular to the opening 32 are formed. In front of the exposure aperture 32, the taking lens 4
Is mounted, and a shutter blade 38 is rotatably mounted between the lens holder 37 and the mechanical base 31 while being biased counterclockwise by a spring 39.

A shutter drive lever 41 and a number-of-photographs display plate 42 are rotatably inserted into the shaft 33. A stop lever 45 is rotatably inserted into the shaft 34.
The rotating body 46 is inserted into the shaft 35. This rotating body 46
In the drawings, the shutter charge cam 47, the winding cam 48, the gear 49, and the one-tooth gear 50 for counter feeding are integrally formed, although they are drawn separately from each other for convenience in the drawings. The tops of the shafts 33 to 35 are finally stopped by a common stopper plate 51. The shutter drive lever 41 is urged in the left-hand screw advancing direction by a compression torsion spring (not shown), and the winding stop lever 45 is urged clockwise by a compression torsion spring (not shown). Also,
The gear 49 has a knurl gear 11 a of the winding knob 11.
Are engaged.

When the exposure unit 13 is in the charged state, as shown in FIG. 4, the vertical projection 41a of the shutter drive lever 41 is in contact with the side surface of the vertical projection 45a of the locking lever 45 and is locked. Lever 4
The protrusion 45b of the fifth member enters the groove 48a of the stop cam 48, thereby preventing the winding operation. When the shutter button 9 is pressed down from this state, the winding stopper lever 45 is rotated counterclockwise by the inclined surface 9c of the claw 9b, and the vertical protrusion 41 is rotated.
a, 45a is released. At the next moment, the shutter drive lever 41 rotates counterclockwise to rotate the shutter blade 38.
Is kicked off, the shutter blade 38 swings, and the exposure opening 32 is opened and closed.

After kicking off the claw 38a of the shutter blade 38, the shutter drive lever 41 pivots to a position over the claw 38a (to the left of the claw 38a in FIG. 4), and the front of the vertical projection 41a (FIG. 4). Is the vertical projection 45a
Of the winding lever 45 by engaging with the rear surface (the lower surface of the drawing)
Prevents the clock from returning in the clockwise direction. In this state, the protrusions 45b of the stop lever 45 extend from the grooves 48a of the stop cam 48.
, The winding knob 11 becomes operable.

When the winding knob 11 is operated to start winding the brownie film 16, the shutter charge cam 47 rotates via the gear 49. With the rotation of the shutter charge cam 47, the outer peripheral surface of the shutter charge cam 47 presses the projection 41b of the shutter drive lever 41 to rotate the shutter drive lever 41 clockwise. As a result, the shutter drive lever 41 is rotated toward the charging position, and moves over the slope of the claw portion 38a of the shutter blade 38 by the action of the compression torsion spring.

Immediately before the shutter charge cam 47 makes one rotation, the front surface of the vertical projection 41a is disengaged from the rear surface of the vertical projection 45a, and the stop lever 45 rotates clockwise.
The protrusion 4 is formed in the groove 48a of the stopping cam 48 which has just rotated one rotation.
5b drops, the winding cam 48 is locked, and the film feed for one frame is completed. At the same time, the projection 41b of the shutter drive lever 41 enters the recess 47a of the shutter charge cam 47, so that the shutter drive lever 41
Is about to be rotated counterclockwise, but the vertical projection 41a
Abuts on the vertical projection 45a of the stop lever 45, the shutter drive lever 41 is locked at the charging position, and the shutter is charged as shown in FIG. In addition, the winding cam 4
Since the one-tooth gear 50 makes one rotation with one rotation of 8,
The number-of-photographs display plate 42 engaged with this is fed by one tooth, and a number corresponding to the number of remaining frames that can be photographed by the brownie film 16 is displayed on the film counter window 10.

While the winding cam 48 makes one rotation, the brownie film 16 is fed one frame.
The rotation angle of the hoisting knob 11 required to make one rotation of the winding cam 48 is constant. That is, spool 2
The rotation angle of No. 4 is constant, and the winding diameter of the spool 24 gradually increases as the film winding proceeds, so that the length of the brownie film 16 fed by one winding operation gradually increases. However, since the A-PEN having a small thickness is used as the base film of the brownie film 16, by making the diameter of the spool 24 sufficiently large, the first frame and the last frame are required for about 15 shots. There is no significant difference in spacing. For example, the thickness of the film is adjusted to the current roll film J120 (JIS K751).
Assuming that the diameter of the spool 24 is 22 mm, which is 30% smaller than that of 2-1961), the difference between the frame intervals of the first frame and the last frame of 15 frames is about 4.3 mm, which is not a problem.

A finder 8 is incorporated in the upper part of the main body base 12. The finder 8 is an Albada-type inverted Galileo finder composed of two objective lenses 8a and 8c and an eyepiece 8b. A view frame and an illustration of a person are provided on a plane far from the eye of the eyepiece 8b. In addition, the scale is formed by aluminum evaporation, and the concave surface of the objective lens 8c is provided with a semi-transparent mirror (see FIGS. 6 and 7). As a result, as shown in FIG. 5, in the finder field 55 of the finder 8, in addition to the field frame 56, an illustration 57 and a scale 58, which are guidelines for focusing, are displayed.

An illustration 57 is an illustration of a subject image when an adult of a standard body at a subject distance that is in focus, for example, a subject distance of 3 m, which is most suitable for commemorative photography, is viewed through the viewfinder 8. By adjusting the subject distance so as to perform shooting, focusing can be easily performed. Similarly, the scale 58 is also used for simple focusing. For example, a person to be a subject has a ruler of 1 m, and the subject distance is adjusted so that the ruler and the scale 58 overlap. Focusing can be performed easily. Of course, the scale 58 may be superimposed on a portion of about 1 m constituting the subject instead of the ruler.

The photographing lens 4 has a 135-type because it has a large depth of field and, as will be described later, commonly uses a strobe unit used in a conventional 135-type film unit with a lens. The focal length (f) is set to 4 so as to obtain the same angle of view in terms of the screen size.
A wide-angle single focal length lens of 8 mm to 56 mm (corresponding to f = 30 mm to 35 mm in a screen size of 24 mm × 36 mm) is preferable. In the present embodiment, the light distribution is not deteriorated when the strobe unit is commonly used. In this way, it was set to 56 mm on the narrow side of the angle of view. Further, the flange back of the photographing lens 4 is determined so that the focus is best at, for example, 3 m. Also, the F of the taking lens 4
The number is, for example, F11. The shutter speed was set to about 1/160 second to prevent camera shake.

The strobe unit 14 is a conventional film unit with a lens loaded with a 135 type photographic film, for example, a unit used in "Super Photo Run" (trade name) manufactured and sold by the present applicant. As shown in FIG. 8, it was arranged at an angle of 90 degrees and above the exposure unit 13. This allows
The cost can be reduced, and the strobe light emitting unit 5 is in the vertical position, which corresponds to the screen size of the aperture 20 which is vertically elongated, and can uniformly illuminate the subject in the shooting range.
Reference numeral 61 denotes a circuit board, and reference numeral 62 denotes a shutter blade 3.
8, a synchro switch short-circuited by the synchro lever 38b, reference numeral 63 denotes an AA battery for power supply, and reference numeral 64 denotes a main capacitor (see FIGS. 1 and 6). Further, the charging switch contacts 65 and 66 printed on the circuit board 61 are short-circuited by an electric contact 67 fixed to the back surface of the charging switch pressing portion 6 (see also FIG. 7).

The guide number (GN) of the strobe unit 14 is as small as about 9, but the photographing lens 4 is
1, f = 56 mm and the shutter speed is 1/160 second, so the ISO 800 is used as the brownie film 16 and considering this film latitude,
As shown in FIG. 9, a subject that satisfies the range α of the oblique line surrounded by the solid line has good focus (allowable circle of confusion is 0.05 mm or less) and proper exposure. The range alpha ₁ below focus range narrower than the dotted line P is one when flash photography. The range β shown for reference is the case of “Super Photo Run” (trade name) loaded with 135 type photographic film manufactured and sold by the present applicant.
Note that the vertical axis in FIG. 9 is the photographic brightness (LV = Light Value) in which the sensitivity value is added to the subject luminance value, and the horizontal axis is the subject distance (m).

The front cover 17 has a film counter window 1
0, an aperture 17a, 17b, 17c for exposing a shutter button 9, a photographing lens 4, a strobe light emitting section 5, a pilot lamp 7, an objective lens 8a for a finder 8, and a slit 17d for forming a charge switch pressing section 6. And a notch 17e exposing the hoisting knob 11. In the center of the rear cover 18, there is formed a pressure plate 18a curved corresponding to the field curvature of the photographing lens 4. On the left and right sides, the back of the patrone storage room 21 and the film roll storage room 22 are provided. The lid 18b which closes the side light-tightly,
18c are provided continuously. Then, the lid 18b, 1
At the upper part of 8c, lids 18d and 18e for closing the upper parts of the patrone storage chamber 21 and the film roll storage chamber 22 are provided continuously through a thin hinge part. At the time of the development processing, the cartridge 15 containing the photographed brownie film 16 can be taken out of the cartridge storage chamber 21 without disassembling the unit body 2 by opening the lid 18d in a pull-top manner.

In order to use the film unit 1 with a lens constructed as described above, first, the winding knob 11 is operated to move the first frame of the brownie film 16 to the aperture 2.
Set to 0. Then, the subject is framed by looking through the finder 8. At this time, the distance to the subject is adjusted so that the size of the subject viewed through the finder 8 becomes the same as the illustration 57 in the finder field of view 55, or the 1 m portion of the subject or almost 1 m near the subject overlaps the scale 58. I do. As a result, the subject distance becomes about 3 m and the desired subject is focused. In fine weather, shooting can be performed by pressing the shutter button 9 as it is, but in cloudy weather or when the subject is dark, flash shooting is performed.

When performing flash photography, the charging switch pressing section 6 is kept pressed with the left finger. When the pilot lamp 7 lights up, the shutter button 9 is depressed. Nail 9
When the slope 9c of b rotates the stop lever 45 to unlock the shutter drive lever 41, the shutter drive lever 41 rotates at a high speed and swings the shutter blades 38. The exposure opening 32 is opened and closed at a shutter speed of about 1/160 second, and at the same time, the synchro switch 62 is short-circuited, so that the strobe light is emitted from the strobe light emitting unit 5 toward the subject. As a result, the subject image is properly exposed to the first frame of the brownie film 16 set in the aperture 20. Hereinafter, the film feeding by the operation of the winding knob 11 and the pressing operation of the shutter button 9 are repeated, and the exposure of the entire frame of the brownie film 16 is performed by accompanying the pressing operation of the charging switch pressing portion 6 as necessary.

After the last frame has been photographed, the winding knob 11 is continuously operated to store all of the brownie film 16 in the patrone 15, and the film unit with lens 1 is submitted to the developing dealer as it is. In the film unit with lens 1 collected from the developing dealer to the developing lab, first, the outer box 3 is peeled off from the unit main body 2, and the lid 18d is removed.
Is opened in a pull-top manner using a jig, and the used brownie film 16 with a patrone is taken out of the patrone storage chamber 21. This operation can be performed efficiently in a bright room because the brownie film 16 is housed in the patrone 15 in a light-tight manner.

The brownie film 16 with the patrone taken out of the patrone storage chamber 21 is developed by an automatic developing machine. Thereafter, the brownie film 16 is printed at the same time as the conventional 135-type film unit with lens. After the brownie film 16 is taken out, the unit body 2 is
After being transported to the inspection process, the exposure unit 13 having no abnormality, each lens of the finder 8, and the strobe unit 14 are reused, and other plastic parts are melted, pelletized, and recycled as a molding material.

In FIG. 10 showing another embodiment, the strobe unit 73 used for the film unit with lens 71 has a different shape from the strobe unit 14. In this strobe unit 73, the AA battery 6
3 is arranged in the horizontal direction, the finder 8 is not arranged above the exposure opening 32, and the film roll storage chamber 2 is not arranged.
2 above. Also, the sync switch 74
Is disposed on the right side of the drawing with respect to the exposure opening 32 and is short-circuited by a projection 38 c integral with the shutter blade 38.

In the embodiment described above, a brownie film with a patrone is used, but the present invention is not limited to this. For example, a commercially available brownie film with a backing paper (120 type) may be used. Good. In this case, for example, a spring plate or the like for holding down the film may be provided in the film take-up chamber to prevent the exposed brownie film from becoming loose.

The subject distance is 3 m suitable for commemorative photography.
The focus is set to be most focused at the time of, but the present invention is not limited to this.
It may be. Further, the present invention is also applicable to a so-called film unit with a lens for close-up photography. That is, the optimum focal length of the taking lens may be set to about several tens cm. In this case, if the strobe unit used is, for example, the same as that used for a 135-type film unit with a lens, it is expected that the subject will be overexposed for a close subject. It is preferable to attach a filter for reducing the amount of irradiation light. Also, close-up photography may be performed by attaching an attachment lens.

Also, regarding the focal length of the taking lens,
If the direction is longer than 56 mm, the strobe unit used in the conventional 135-type film unit with lens can be used as it is, so that a longer focal length can be obtained in consideration of the focus range. It is possible to set it on the distance side.

Further, a type in which the pressing portion for the charging switch is kept pressed at least until the charging is completed is used as the strobe unit.
No. 9, a strobe unit that continues charging operation by one charging switch ON can be used. Also, the Brownie film was shot 15 times, but may be shot 30 times, for example. Further, the form of the illustration or scale displayed in the viewfinder field is not limited to the one shown in the drawings.
