DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera for preventing a finger from being photographed and a strobe light from being blocked during photographing.

[0002]

2. Description of the Related Art A film unit with a lens (hereinafter referred to as a film unit) in which a film is pre-installed at the time of manufacture is widely used as a single-use simple camera in which the film cannot be exchanged. It is one of the features. In recent years, in addition to a film unit using a 135-type film cartridge, a film unit using an IX240-type film cartridge, which is a smaller film cartridge, has appeared, and the size of the film unit body has been further reduced. .

[0003] When taking a picture while holding the film unit body and performing operations, as with many popular cameras, the right hand wraps around one side of the film unit and holds it with the index finger on the top of the camera. It is usual to take the stance of operating the buttons. As described above, since the film unit is downsized, when holding the film unit body in such a normal posture, the right hand finger that is held accidentally enters the angle of view of the photographic lens and appears in the print photo. That is, a so-called finger image may occur.

Some film units with a flash device have a flash button, which is a flash emission operation member for controlling ON / OFF of the flash device, provided outside. In such a film unit, the strobe button is a strobe light emitting portion or
If the camera is located near the taking lens, the hand that operates the strobe button may cut off a part of the strobe light-emitting unit during shooting, or a finger may appear as in the case of the shutter button described above. Sometimes.

[0005] In order to solve such a problem as the finger image caused by the downsizing of the film unit, for example, in Japanese Patent Application Laid-Open No. H10-161206, a ridge for finger catching is provided on a grip portion of the film unit. It has been proposed to prevent the finger holding the film unit from entering the lens angle of view by touching the ridge with the finger.

[0006]

However, as the film unit body has been reduced in size so that it can be easily wrapped in the palm, the ridges must be relatively small. Even in the case where it is provided, it may not be possible to prevent the finger holding the film unit main body from entering the angle of view of the photographing lens, and there is a problem in terms of certainty.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has as its object to provide a camera which is low-cost and can more surely prevent finger image pickup and the like without impairing miniaturization. is there.

[0008]

In order to achieve the above object, the present invention provides a camera having an externally operable shutter button, wherein the shutter button is provided on a front surface of a camera body provided with a taking lens. The position of the end of the shutter button close to the taking lens is at least 20 mm away from the center of the taking lens and below the center of the taking lens, or the shutter button is provided on the side of the camera body. The button is pressed in a horizontal direction toward the camera body. By isolating the position of the shutter button itself from the photographing lens for a certain distance, the photographer holds the camera toward the subject and operates the shutter button with the index finger to take a stance at the time of shooting, not to mention the index finger, Other fingers are necessarily positioned outside the angle of view of the taking lens. Since the shutter button is a member that must be operated at the time of photographing, the shutter button is a compulsory opportunity to retract the finger out of the angle of view of the photographing lens, and it is possible to reliably prevent the finger from being photographed.

Further, in a camera having a strobe device comprising an externally operable strobe button and a strobe light emitting portion, the end of the strobe button near the taking lens is separated from the center of the taking lens by 35 mm or more, and the strobe light is emitted. The position of the end near the section is separated from the center of the strobe light emitting section by 20 mm or more. As with the shutter button described above, the O
The position of the strobe button itself for controlling N / OFF is separated from the taking lens and the strobe light emitting unit by a certain distance, so that a finger is captured within the angle of view of the taking lens and the strobe light is blocked when the photographer is ready to take a picture. Can be prevented.

When the charging is completed, the neon tube incorporated in the circuit board 43 is turned on, and the photographer can confirm that the neon tube is turned on through the strobe charging completion display window formed on the rear cover 4. When the synchro switch 42 is closed in conjunction with the opening and closing of the shutter blades 33 when the shutter button 14 is pressed, a trigger signal is given to the strobe circuit and strobe light emission is performed.

The operation of the above configuration will be described below. When the film is fed one frame by rotating the winding knob 28, the shutter mechanism including the shutter kicking member 35, the shutter charge holding member 36, and the like incorporated in the exposure unit 16 is linked to complete the shutter charging. At this time, the winding stop lever 36b integrally formed with the shutter charge holding member 36 locks the rotation of the winding knob 28, and the winding stop mechanism operates.

After checking the subject except for the viewfinder, the photographer places his right index finger on the shutter button 14. The shutter button 14 is located on the same front surface as the taking lens 11, and the end 17 of the button 14 near the taking lens has a distance L1 from the center of the taking lens 11 of 20 m.
Since it is located at a distance of m or more, the index finger of the right hand does not enter the angle of view of the photographing lens 11. And since the shutter button 14 is located on the front part,
When the index finger of the right hand is placed on the shutter button 14, the thumb of the right hand supports the back of the film unit 1 and does not enter the angle of view of the photographing lens 11. Further, the other right hand fingers are also positioned below the right hand index finger and do not enter the angle of view of the photographing lens 11.

When performing flash photography, the flash button 15 is pressed with the left forefinger. An end 20 of the strobe button 15 near the taking lens has a distance L2 from the center of the taking lens 11 of 35 mm or more, and an end 21 near the strobe light emitting portion has a distance L3 from the center of the strobe light emitting unit 13.

Nor. Then, the left thumb supports the back of the film unit 1 and the other left fingers are positioned below the left index finger, so that they enter the angle of view of the taking lens 11. There is no cover of the flash light emitting unit 13.

In the case of flash photography, the completion of charging of the flash is confirmed in the charging completion display window, and the shutter button 14 is pressed down while holding the above-mentioned attitude. As described above, the shutter mechanism operates and the shutter blades 33 open and close. At the same time, the synchro switch 16 is operated, and strobe light emission is performed. At this time, since the photographer holds the above-mentioned posture, there is no finger covering the strobe light emitting unit 13,
Since the strobe light is not blocked, and no finger has entered the angle of view of the photographing lens, no finger appears on the image formed on the film 10. As described above, by holding the film unit and holding the film unit at the time of photographing, it is possible to surely prevent a finger image and a part of strobe light from being blocked.

FIG. 5 shows a second embodiment in which the present invention is applied to a film unit with a lens. Note that the first
The same reference numerals are given to members common to the first embodiment. In this embodiment, the shutter button 50 is provided on the side surface of the film unit main body. As shown in FIG. 6, the shutter button 50 is provided with a lever portion 50a for rotating the shutter charge holding member 36 constituting the shutter mechanism of the above-described first embodiment. It straddles from the upper surface and is in contact with the pressed portion 36c of the shutter charge holding member 36. With the shutter charge, the pressing portion 36c is moved to the lever 5
When 0a is pressed, shutter charging is completed. The strobe button 15 is provided at the same position as in the first embodiment.

The operation of the above configuration will be described below. When the photographer is ready to take a picture, the shutter button 50 is located on the side, so the right palm cannot be held so as to wrap the side, and the right forefinger is placed on the shutter button 50, At least, the film unit 1 is gripped and held by the right thumb and the middle finger of the right hand. For this reason, not only the forefinger above the shutter button 50 on the side surface but also the right hand inevitably retreats out of the angle of view of the photographing lens 11.

In this state, the shutter button 50 is depressed, and the above-described shutter mechanism is operated to perform photographing. Since the above-described attitude is maintained even during photographing, no finger appears in the image formed on the film 11. Even when performing flash photography, the flash button 15
Since the strobe light is provided at the same position as in the first embodiment, the strobe light does not cover the strobe light emitting portion 13 and does not enter the angle of view of the photographing lens 11. Therefore, by taking a stance at the time of photographing, it is possible to reliably prevent the finger image and the strobe light from being partially blocked.

FIG. 7 shows a third embodiment in which the present invention is applied to a film unit with a lens. Note that the first
The same reference numerals are given to members common to the first embodiment. In this embodiment, the shutter button 52 is provided at the conventional upper position, but the position of the strobe button 53 is provided to the left as viewed from the front of the front part, and the shutter button 52 is provided.
And close proximity. Therefore, the shutter button 52 can be operated with the forefinger of the right hand and the flash button 53 with the middle finger, and one-hand operation of the film unit is possible. An end of the strobe button 53 near the taking lens and an end near the strobe light emitting portion are common to the end 54. The end 54 has a distance L2 from the center of the taking lens 11 of at least 35 mm and is strobed. The distance L3 from the center of the light emitting unit 13 is provided at a position separated by 20 mm or more.

As shown in FIGS. 8A and 8B, the strobe button 53 is interlocked with the switch piece 19, and the interlocking member 5 directly in contact with the strobe button 53.
Reference numeral 6 is attached to a shaft 6b provided in the cartridge storage chamber, and is urged by a spring 57 in a counterclockwise direction when viewed from above. An interlocking member 58 that is in direct contact with the switch contact piece 19 is mounted on a shaft 3a that protrudes from the rear side of the front cover 3 and is urged by a spring 59 in a clockwise direction when viewed from above. By pressing the strobe button 53,
The interlocking member 56 rotates clockwise as viewed from above,
The interlocking member 58 is pressed to rotate the interlocking member 58 in a counterclockwise direction. Due to this rotation, the interlocking member 58 presses the switch contact piece 19, and the gap 45 between the contact pieces of the strobe circuit.
Is closed to start flash charging. With this interlocking mechanism, the strobe button 5 can be used without significantly changing the internal structure of the film unit such as the position of the strobe device 18 and the position of the exposure unit 16.
3 can be moved.

The operation of the above configuration will be described below. At the time of photographing, the shutter button 52 can be held with one finger by operating the shutter button 52 with the index finger of the right hand and the flash button 53 with the middle finger of the right hand when performing flash photography. At this time,
The middle finger is moved to the position of the strobe button 53, and the position of the strobe button 53 is separated from the taking lens 11 by a predetermined interval. Furthermore, the shutter button 52 on the upper surface
The other finger as well as the index finger above it is located outside the angle of view of the photographing lens 11 as well. Similarly, the flash light emitting unit 13 is separated from the flash light emitting unit 13 by a predetermined distance, so that the flash light emitting unit 13 is not covered with a finger.

Since the shutter button 52 is depressed in this state of photographing and the photographing is performed, the stroboscopic light-emitting portion 13 is covered and part of the strobe light is blocked, or the photographing lens 11 enters the angle of view. Does not occur. Therefore, by taking a stance at the time of photographing, it is possible to reliably prevent the finger image and the strobe light from being partially blocked.

Although the present invention has been described with reference to the illustrated embodiment, the present invention can be equally applied not only to a film unit with a lens in which a film is pre-loaded at the time of manufacture but also to a general simple camera. Yes,
In implementation, appropriate changes can be made. For example, although the strobe button is used for controlling the strobe charging start operation, any function may be used as long as the function for inhibiting strobe light emission is used for strobe light emission control instead of charging. If the positions of the shutter button and the strobe button are predetermined positions, the shutter button and the strobe button need not necessarily have the interlocking mechanism of the present embodiment.

[0031]

As described above, according to the camera of the present invention, the position of the shutter button and the strobe button is set at a predetermined distance from the photographing lens or the strobe light emitting portion, so that a so-called finger image or strobe light can be obtained. It is possible to reliably prevent partial interruption of light only by taking a stance during shooting. Further, since the present invention merely changes the positions of the shutter button and the strobe button, there is no need to change the size of the camera body, and if the present invention is implemented in the form described in the embodiment of the present invention, The above effect can be realized without making a significant change to the configuration of the camera. As a result, even if the present invention is applied to a film unit, the characteristics of the film unit such as small size and low cost are not impaired.
