Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera, and more particularly, to a camera in which each member can be optimally arranged to reduce the size.

[0002]

2. Description of the Related Art In recent years, compact cameras using so-called 35 mm film containing film have been equipped with various electronic devices due to automation, and a large-capacity lithium battery is used as a battery to supply power to these devices. It is supposed to be. As a member provided in the camera by this automation, for example, an automatic film winding and rewinding device, a photographing lens drive motor for retracting the lens barrel, autofocusing, a reflective umbrella for a built-in flash, and the like. There is a capacitor for supplying voltage to this built-in flash, and with these, the camera tends to become larger and larger.

In order to alleviate such an increase in size as much as possible, an example of a camera in which the arrangement of strobes is taken into consideration is disclosed in, for example, Japanese Utility Model Laid-Open No. 3-62328. In the strobe arrangement structure of the camera described in this publication, a strobe support plate for popping up the strobe is arranged in a substantially triangular space formed between the film chamber and the battery chamber.

In Japanese Patent Publication No. 61-14499, a finder portion is arranged between the patrone chamber arranged along the short side on the right side of the aperture opening and the right side surface of the camera, and the left side of the aperture opening portion. There is described a small camera in which a battery storage chamber is arranged between a hoisting machine room arranged along the short side and a left side surface of the camera.

Further, in Japanese Unexamined Patent Publication No. 2-166433, a lens is provided at a lower position of an image frame within a step formed in the winding axial direction by a film winding chamber and a cartridge chamber, on the winding chamber side. A camera is disclosed in which a drive motor is arranged such that its rotation axis is parallel to the optical axis, and a control circuit is arranged on the side of the cartridge chamber.

By the way, Japanese Patent Laid-Open No. 3-294848 proposes a film patrone of a type in which a spool member around which a film stored in a patrone is wound is rotated by a camera member and is sent out of the patrone. This film cartridge is a 135-inch film cartridge (JIS
Unlike K7519), the spool shaft does not project out of the cartridge in the axial direction.

[0007]

However, in the one disclosed in Japanese Utility Model Laid-Open No. 3-62328, the shape of the space is substantially triangular, but the members to be housed therein are not substantially triangular. , I couldn't say that the space was used effectively.

Further, in the one described in Japanese Patent Publication No. 61-14499, the layout necessary for incorporating the taking lens drive motor, the reflector of the built-in strobe, the condenser, etc. is not described, so these members are incorporated. It cannot be applied as is to small cameras that have become increasingly electronic.

Further, considering that the technical means disclosed in Japanese Patent Laid-Open No. 2-166433 is applied to a camera using the film cartridge described in Japanese Patent Laid-Open No. 3-294848, a film winding chamber and a film cartridge are considered. Since the step formed in the step is small, in the structure in which the lens drive motor is housed in the lower part of the image frame in the step, the camera is not downsized even if the film cartridge is downsized.

The present invention has been made in view of the above problems, and has a high storage efficiency of each member provided inside,
It is an object of the present invention to provide a camera that can be made smaller than before.

[0011]

In order to achieve the above object, the camera according to the present invention sets the height of the camera body to the minimum value determined by the axial dimension of the film cartridge, and the camera for photographing. In a camera in which a film winding chamber and a cartridge chamber are arranged across the opening, a substantially cylindrical battery chamber is provided so that a substantially triangular space is formed by the film winding chamber or the cartridge chamber, In this substantially triangular space, at least one of a substantially cylindrical strobe reflector and a light receiving portion or a light emitting portion for autofocus is arranged.

Further, in the camera according to the present invention, the height of the camera body is set to the minimum value determined by the axial dimension of the film cartridge, and the film winding chamber and the cartridge chamber are arranged with the photographing opening interposed therebetween. In the camera
A substantially cylindrical battery chamber and a strobe capacitor are provided in an overlapping manner on one of the film winding chamber and the cartridge chamber on the camera body side.

In the camera according to the present invention, the height of the camera body is set to the minimum value determined by the axial dimension of the film cartridge, and the film winding chamber and the cartridge chamber are arranged with the photographing opening interposed therebetween. In the above camera, a film drive motor is disposed between the photographing opening and the film winding chamber so that the drive shaft is perpendicular to the film running direction.

Further, in the camera according to the present invention, the film winding is sandwiched so that the end face of the film winding chamber and the end face of the film cartridge stored in the cartridge chamber are substantially flush with each other with the photographing opening interposed therebetween. A camera in which a chamber and a cartridge chamber are arranged, a photographing lens drive motor for driving a photographing lens is arranged in a film traveling direction below the photographing opening, and the photographing opening and the film winding are arranged. A film drive motor is provided between the chamber and the chamber so that the drive shaft is perpendicular to the film running direction, and the height of the camera body is set to the minimum value determined by the axial dimension of the film cartridge. .

In addition, in the camera according to the present invention, the film to be used is 35 mm or less, and the minimum height of the camera body is determined by the axial dimension of the film cartridge corresponding to the film to be used. A shutter release button is provided substantially at the center, and two corners formed by the rear surface of the camera, both side surfaces of the camera and the upper surface of the camera are chamfered so that the shutter release button can be pressed regardless of the holding direction. A camera characterized by making it easier.

On the right side of the front surface of the upper cover 2, as shown in FIG.
Is provided with a horizontally long linear protrusion 2a,
As shown in FIG. 4, it is arranged immediately below the strobe reflector 11.

Further, a large, for example, circular shutter release button 22 as shown in FIG. 5 is arranged at a substantially central portion of the upper end surface of the upper cover 2 in the camera width direction.
The shutter release button 22 is of a push button type and has a center portion 22a, a right side portion 22b, and a left side portion 22c.

As shown in FIG. 5, the large shutter release button 22 provided on the small camera and the inclined surface 2g formed by the inverted triangular R surface of the upper cover 2 have the functions at the shutter release operation. Will be described with reference to FIGS.

When the shutter release button 22 is operated with the index finger of the right hand or the index finger of the left hand, as shown in FIG. 7, FIG. 8, FIG. 10, and FIG. The palm side or the palm side of the third joint is hooked on the inclined surface 2g having the R surface, and the fingertip of the forefinger can be naturally released on the shutter release button 22 for release operation.

Moreover, the shutter release button 22 is
As described above, since the release can be performed by pressing any of the central portion 22a, the right side portion 22b, and the left side portion 22c, it is suitable for people with large or small hands, or people with long or short fingers. Can respond. Further, when the camera is held, as shown in the drawing, the index finger and fingers other than the thumb do not cover the AF light projecting portion 19 and the AF light receiving portion 20, and do not obstruct the view of the finder 16. Then, as shown in FIGS. 10 and 11, when the release operation is performed with the index finger of the left hand, the projection 2a of the upper cover 2 can prevent the strobe reflector 11 from being covered with the hand.

On the other hand, as shown in FIGS. 9 and 12, when releasing with the thumb of the right hand or the thumb of the left hand, the second joint of the thumb fits the inclined surface 2g and holds the camera without difficulty. can do.

In this way, whether the camera is set to the vertical screen position or the horizontal screen position, whether the right hand or the left hand is used, the thumb or the index finger of both hands is further used. Even in the case of using, it is possible to release freely in a state where it is easy to hold without disturbing AF etc., and a good usability can be obtained.

Although the corners are chamfered in the above description,
The invention is not limited to this, and can be widely applied as long as it has a chamfered shape that easily holds the camera.

According to the first embodiment as described above, by disposing the stroboscopic reflector 11 having a substantially triangular shape in the substantially triangular space provided between the cartridge chamber 5 and the battery chamber 8, the dead inside the camera can be reduced. The space can be used effectively. Further, since the battery chamber 8, the capacitor 9 and the strobe circuit board 10 are arranged in the immediate vicinity of the portion where the strobe is arranged, not only the assembly is easy, but also the circuit connection from the capacitor 9 to the strobe discharge tube 12 is performed. There is also an advantage that the lead wire can be shortened, the loss of electric energy is small, and the efficiency is high.

Moreover, since the distance from the center of the optical axis of the taking lens 13 to the strobe reflector 11 is also large, the so-called red-eye phenomenon that may occur during strobe photography is less likely to occur. Further, since the projection 2a is provided, the strobe reflector 11 is not covered with the hand even when the camera is held with the left hand.

In the above description, the cartridge chamber 5, the battery chamber 8 and the condenser 9 are provided on the right side of the aperture opening 4, and the strobe reflector 11 is arranged between them, but the spool chamber 6 and the battery chamber 8 are provided on the right side. The same effect can be obtained by providing the condenser 9 and disposing the strobe reflector 11 between them.

The weight occupied by the battery chamber 8 and the capacitor 9 in the space of the camera parts is high. According to the first embodiment as described above, the battery chamber 8, the capacitor 9 and the strobe circuit board 10 are overlapped and arranged on the end face portion of the camera, so that the space in the height direction of the camera can be effectively used and the storage efficiency is good.

Further, by rotating the spool shaft, which is disclosed in the above-mentioned JP-A-3-294848, on which the film accommodated in the cartridge is wound by the driving member of the camera, the film feeding of the cartridge is carried out. When a patrone of the type that feeds the film from the outlet is used, the rotational speed of the spool for winding the film in the spool chamber of the camera must be faster than the rotational speed of feeding the film in the patrone.
That is, in order to reliably wind the spool on the spool of the camera, the speed reduction ratio of the spool shaft in the cartridge is increased (that is, the rotation speed is slowed), while the speed reduction ratio of the spool of the camera is decreased ( In other words, increase the rotation speed)
There is a need to.

According to the first embodiment, since the film drive mechanism 15 having the above arrangement is provided, the film drive motor 14 to the film drive fork is more than the drive distance from the film drive motor 14 to the spool gear 15b. Since the driving distance up to 15a is longer, it is possible to realize the reduction ratio as described above without difficulty by properly combining gears and the like.

Further, since the film driving motor 14 is arranged on the left side of the aperture opening 4, the lateral width of the camera with respect to the taking lens 13 is well balanced, and the camera holding property is also improved.

In the above description, the case of using the film with a cartridge disclosed in Japanese Patent Laid-Open No. 3-294848 is used, but the invention is not limited to this and a 135 type film cartridge of JIS K7519 is used. It goes without saying that it can also be applied to a camera that does.

The 135 type film cartridge of JIS K7519 has the end face 2 of the long hub 23 as shown in FIG.
3a and the film width end face have a step L. On the other hand, in the film cartridge disclosed in JP-A-3-294848, since the long hub 23 as shown in FIG. 6 does not project from the cartridge body 24, the dimension L becomes smaller accordingly. The above-mentioned four conventional techniques cannot be applied as they are.

Therefore, in the first embodiment, since the width direction of the film is the long side of the screen size, the image circle diameter of the taking lens can be reduced and the outer diameter of the lens barrel 7 can be reduced. JP-A-3-29484
Even if the cartridge film disclosed in Japanese Patent No. 8 is used, the photographing lens drive motor 17 is arranged substantially below the center of the aperture opening 4 and the lens barrel 7 is retracted without increasing the space. be able to.

The drive axis of the photographic lens drive motor 17 is arranged in the film feeding direction, but a photographic lens drive mechanism 18 for converting the movement direction by 90 ° is provided between the cartridge chamber 5 and the lens barrel 7. Since it is arranged, the deceleration necessary for driving the lens can be performed without difficulty.

13 and 14 show the second embodiment of the present invention. In the second embodiment, the above-mentioned first
A description of the same parts as those in the embodiment will be omitted, and only different points will be mainly described.

A strobe reflector 11 is arranged on the upper side and an AF light receiving section 20 is arranged on the lower side in a substantially triangular space on the front side between the cartridge chamber 5 and the battery chamber 8. By arranging the AF light receiving unit 20 in the substantially triangular dead space as described above, the distance from the AF light emitting unit 19 is increased, the effective base line length is increased, and the AF light receiving unit 20 is moved to be vacant. The space in the vicinity of the photographing lens drive mechanism 18 can be used for other purposes.

In the second embodiment, the AF light receiving section 2
Although 0 is arranged in the substantially triangular space, the position of the AF light projecting portion 19 is replaced with that of AF in the substantially triangular space.
The light projecting section 19 may be arranged.

Also, in the second embodiment, the battery chamber 8 is
Does not have a cylindrical shape, but has a shape in which the side that is the side surface of the camera is partially cut out, and the cutout side also serves as an exterior member of the camera to hold the battery.
As a result, it is possible to further reduce the weight and reduce the size of the camera in the lateral direction by the thickness of the battery chamber.

According to the second embodiment, the same effect as that of the first embodiment can be obtained, and the active autofocus can be made more accurate and reliable. The space inside the camera can be used more effectively.

[0051]

As described above, according to the present invention, it is possible to provide a camera which has a high storage efficiency for each member provided inside and which can be made smaller than conventional ones.
