DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera having a slide-type protective case.

[0002]

2. Description of the Related Art Conventionally, a simple exposure mechanism is provided so that anyone can easily enjoy photographing, and an unexposed photographic film and a cartridge are previously loaded at the time of manufacture, so that cumbersome film loading and rewinding operations are not required. A film unit with a lens (hereinafter, referred to as a "film unit") is well known. This film unit is
It is established in the market as a kind of inexpensive camera that is used once.

[0003] As a film unit, for example, "Sharp Run Super 800" (trade name) is manufactured by the present applicant.
Sold. This film unit has a shape in which a front surface of the cartridge storage chamber is used as a grip portion and a portion around the taking lens other than the grip portion is recessed to reduce the thickness. Recently, a film unit with a lens loaded with an IX240 film cartridge smaller than a 135-type photographic film cartridge has also been manufactured and sold by the applicant as "Sharp Run Super Slim" (trade name). . In this film unit, the thickness and the profile are reduced by the size of the built-in small cartridge.

[0004] Although a small film unit is excellent in portability, it is difficult to hold the film unit for actual photographing, and a finger may be caught on a photographing lens and photographing may fail. In order to solve this, an invention has been made in which a projection is provided around the taking lens to warn the photographer of finger-holding, but providing a projection around the taking lens is not preferable in the design of the camera. ,
It was not very effective.

[0005] Therefore, a slide case for covering a photographing lens, a strobe light emitting portion, and a shutter button is provided on a body main body in which a photographing mechanism is incorporated, and the slide case is slid in a direction to expose the photographing lens, the strobe light emitting portion, and the shutter button. The camera was designed to be used as a grip to hold the body when the camera is turned on.
It has been proposed by the invention described in Japanese Patent No. 60731.

[0006]

However, in the camera described in the above-mentioned publication, the shutter button is arranged on the body body, and the shutter button is covered with the slide case when not in use. In this case, when the slide case is pulled out and the pulled-out part is used as a grip, the gripped finger separates from the taking lens, so that a failed photograph such as a finger image can be prevented. There is a drawback that the shutter button is also separated and the gripped finger is hard to touch. In addition, the shutter button is exposed in a recessed position. For this reason, it was very hard for people with thick fingers to press.

An object of the present invention is to solve the above-mentioned problem, and an object of the present invention is to provide a camera which can easily operate a shutter release when a slide case is pulled out and used as a grip.

[0008]

In order to solve the above-mentioned problems, a camera according to the present invention has a built-in shutter mechanism and a body body provided with a taking lens exposed to the outside. A shutter button is formed on the outer surface so that the shutter button is formed on the outer surface so as to be movable between an unused position covering an area including the photographing lens from a side surface on the grip side and a photographing position protruding toward the grip and exposing the photographing lens. Outer case, and one end is provided on the body main body so as to be exposed to the outside, and when the outer case is at the shooting position, the one end moves in conjunction with a release operation of a shutter button to operate the shutter mechanism, In addition, there is provided a link lever for releasing the link with the shutter button when the outer case is moved to the non-use position.

And a spool 52 around which the photo film 51 is wound,
And a cartridge 53 for rotatably storing the spool 52.

An aperture 54, which is an exposure light path, is formed in the center of the main body base 45, and a cartridge chamber 55 and a film roll chamber 56 are formed on both sides thereof. The cartridge chamber 55 and the film roll chamber 56
After the rear cover 41 is attached to the rear surface, a cartridge 53 and a film roll 51a obtained by rolling the photographic film 51 drawn out of the cartridge 53 into a roll shape are housed therein. It becomes light-tight by closing. These bottom covers 20 and 57 are provided in a pull-top manner below the rear cover 31. In addition,
A notch 20a for inserting a driver is formed in the cartridge chamber bottom cover 20.

At the top of the cartridge chamber 55, a hoisting knob 14 is provided. A part of the winding knob 14 is exposed to the outside from an opening 58 provided in the rear cover 41. A fork is formed on the lower surface of the winding knob 14, and the fork is engaged with a spool 52 inside the cartridge chamber 55. When a film winding operation is performed from the outside, the spool 52 is rotated in the film winding direction (the direction of the arrow shown in the figure), and the photographed photo film 51 is wound into the cartridge 53.

A check pawl 59 is formed integrally with the main body base 45. The check pawl 58 is engaged with the outer periphery of the winding knob 14 to allow rotation in the film winding direction, and prevents rotation in the film feeding direction (the direction opposite to the film winding direction).

A finder eyepiece window 60 is provided on the rear cover 41.
And a charge completion display window 29 (see FIG. 5) for visually confirming the charge completion lamp of the strobe unit 43 to the outside.

As shown in FIG. 7, the link lever 25 is rotatably attached to a shaft 40a provided on the inner wall of the upper surface of the front cover 40. The one end 25a is connected to the front cover 4
0 is exposed from an opening 24 provided on the left side surface. The front and rear edges of the opening 24 regulate the amount of rotation of the one end 25a. The shutter button 23 is located on the upper surface of the front cover 40 when the outer case 12 is in the non-use position, and does not push down. When the outer case 12 is moved to the photographing position, the shutter button 23 is moved to a position where it comes out of the upper surface of the front cover 40, and the release operation is allowed here for the first time. When a pressing operation is performed here, the shutter button 23
Is in contact with one end 25a of the link lever 25.

As shown in FIG. 8, a slope is formed at one end 25a of the link lever 25. Therefore, when the lower surface of the shutter button 23 comes into contact with the shutter button 23, the link lever 25 rotates clockwise about the shaft 40 a to rotate the other end 25.
b is the state of the operating position for operating the shutter mechanism.
When charging is completed by the film winding operation, the shutter mechanism pushes the other end 25b and again operates the link lever 25.
To the standby position where the lower surface of the shutter button 23 contacts.

Next, the operation of the above configuration will be described. In the manufacturing process of the film unit 10 of the present invention, the front cover 40 and the rear cover 41 are respectively put on the front and rear of the main body base 45 to which the exposure unit 42 and the strobe unit 43 are attached, and after the photographic film cartridge 44 is loaded, The bottom lids 20 and 57 are closed, and the assembly of the unit main body 11 is completed.

Next, the outer case 12 is inserted from the end of the grip 19, and the projection 27 is engaged with the elongated hole 26. This engagement can be performed smoothly by pressing the front and back surfaces of the outer case 12 to expand the upper surface. Then, outer case 1
2 is pulled to a position where the end of the opening 22 covers the photographing lens 13, thereby completely covering the range from the grip portion 19 to the photographing lens 13 as shown in FIG. As a result, the taking lens 13, the finder objective window 48, the finder eyepiece window 60, and the charging completion display window 29 are connected to the outer case 12.
And dust or sand or foreign matter enters the inside of the unit main body 11 through a gap between these openings during transportation or the like, causing a failure of the film unit 10 or
Alternatively, it is possible to prevent photographic properties from being affected. Further, since the shutter button 23 provided on the outer case 12 is located on the upper surface of the front cover 40, the shutter mechanism does not operate even if pressed by any force during transportation.

When photographing, as shown in FIG. 3, the outer case 12 is slid to the photographing position, and the protruding portion of the outer case 12 is used as a grip. As a result, the holding property is improved, and the gripped finger is separated from the photographing lens 13, so that a failure photograph such as a finger image can be reliably prevented.

When the outer case 12 is moved to the photographing position, the photographing lens 13, the finder objective window 48, the winding knob 14, the finder eyepiece window 60, and the charging completion display window 2
9 is completely exposed from the outer case 12. The shutter button 23 is connected to the link lever 2 exposed from the opening 24.
5 is located on one end 25a. In this state, first, the winding knob 14 is rotated until the film is stopped, and then the framing is performed and then the shutter button 23 is pressed. Then, the link lever 25 rotates clockwise about the shaft 40a.

As shown in FIG. 8, a shutter mechanism, a film winding mechanism, a film counter mechanism, etc. of the exposure unit 42 include a sprocket 73, a shutter driving lever 74, a locking lever 75, a charge cam 76, It comprises a winding cam 77, a number display plate 78, a shutter blade 79, and the like.

The sprocket 73 includes a photographic film 51.
The photographic film 51 is rotated at a predetermined phase by one frame. The predetermined rotation of the sprocket 73 is transmitted to a charge cam 76 and a winding cam 77 provided coaxially with the sprocket 73. When the stop cam 77 rotates in response to the transfer of one frame of film, the concave portion 77 a provided on the outer periphery of the cam faces the claw 75 a of the locking lever 75. Lock lever 75
Is urged by a spring 80 in a direction in which the pawl 75 a comes into contact with the stop cam 77. Therefore, the claw 75a of the locking lever 75 in the recess 77a enters, and the locking lever 75 rotates clockwise. At this time, the locking position of the locking lever 75 for preventing the rotation of the sprocket is set.

The locking lever 75 has a locking piece 75 that meshes with a tooth row on the outer circumference of the winding knob 14 at the locking position.
b is provided. Therefore, when the locking lever 75 is rotated to the winding position, the locking piece 75b is engaged with the tooth row on the outer periphery of the winding knob 14 to prevent this rotation operation.
In addition, the other end 25 of the link lever 25 is
When the lever b is engaged and rotates to the winding stop position, the other end 25b is pushed to rotate the link lever 25 to the standby position. Thereby, the link lever 25 is reliably returned to the position where the lower surface of the shutter button 23 abuts. Note that the linkage lever 25 may be provided with a spring that biases toward the standby position. In this case, it always returns to the standby position after the pressing operation of the shutter button 23 is completed.

The rotation of the sprocket 73 in response to the transfer of one frame of film is transmitted to a gear 81 provided concentrically with the sprocket 73, and the gear 81
Step 8 by one division.

The shutter drive lever 75 rotates between a release position and a release completion position, and is urged by a spring 82 toward the release completion position. The predetermined rotation of the sprocket 73 is also transmitted to the charge cam 76. When the charge cam 76 rotates, the shutter drive lever 7
4 is pressed to rotate the shutter drive lever 74 toward the release position against the bias of the spring 82. When the shutter drive lever 74 rotates to the release position, the rising piece 74b of the shutter drive lever 74 engages with the falling piece 75c of the locking lever 75 at the winding stop position, and the locking lever 75 holds the shutter driving lever 74 at the release position.

When the shutter is released, the link lever 25 is rotated clockwise as described above, and the other end 25b pushes the locking piece 75b to move the locking lever 75 to the unlocking release position (counterclockwise). And rotate it. At this time, the engagement between the falling piece 75c and the rising piece 74b is released, and the shutter drive lever 74 is instantaneously rotated toward the release completion position by the bias of the spring 82. During this time, the kick arm 74c provided on the shutter drive lever 74 kicks one end 79a of the shutter blade 79. The shutter blade 79 rotates about the shaft 79b as one end 79a is kicked off, and fully opens the shutter opening 84. Thereafter, the shutter blade 79 is returned to a position where the shutter opening 84 is blocked by the pullback spring 85.

When the shutter drive lever 74 is rotated to the release completion position, the falling piece 75c and the rising piece 74d of the locking lever 75 located at the lock release position are engaged with each other, and the shutter driving lever 74 is moved to the locking lever 75. In the unwrapped position. This allows the next film winding operation.

When not in use, the outer case 12 is slid to an unused position. Thereby, the unit body 11
The outer case 12 is moved to a position where the inner surface follows the contour outline of the film unit 10, and the lateral length of the film unit 10 becomes shorter than that of the photographing position. Further, regardless of the slide position of the outer case 12, only the number-of-photographs display window 18 is always exposed, so that the number of photographed images can be checked quickly. Further, since the flash charging switch 17 is always exposed, flash charging can be performed quickly by charging the flash in advance.

The film unit 10 after completing the photographing for all the photographing frames is submitted to the developing laboratory. At the developer, it is confirmed that the outer case 12 has been moved to the unused position. In this case, since the cartridge chamber bottom cover 20 of the unit body 11 overlaps the area of the perforation 31 of the outer case 12, if the driver is inserted toward the mark area 31a of the perforation 31 in this state, the perforation can be easily performed. The area 31a of the base 31 is broken and the insertion opening 20 of the bottom lid 20 is opened.
The driver's tip can be guided to a. By prying the screwdriver as it is, the bottom cover 20 can be opened as before. At this time, the area of the outer case 12 corresponding to the bottom cover 20 is also broken along the perforations 31, so that it is not necessary to remove the outer case 12 one by one. Thereafter, the cartridge 53 is taken out of the cartridge chamber 55, and the taken-out cartridge 53 is set in a developing machine, so that development and printing can be performed as in the conventional case.

In the above-described embodiment, a film unit with a lens in which a photo film cartridge is built in advance has been described. However, the present invention is not limited to this. The present invention is applicable to a camera loaded with a photo film and used. It goes without saying that you can do it. Further, the position of the shutter button is not limited to the upper surface, but may be anywhere on the outer surface. Further, the mechanism for linking and releasing the link between the shutter button and the link lever is not limited to the mechanism of the above-described embodiment, and any known mechanism can be used.

[0038]

As described above, in the present invention, since the shutter button is provided on the outer case, the position of the shutter button with respect to the outer case does not change even if the outer case is moved to the photographing position. Your finger reaches the shutter button without fail. Moreover, since the shutter button is provided on the outer surface of the outer case, the shutter release can be performed smoothly. In addition, since the linkage between the shutter button and the link lever is released by moving the outer case to the non-use position, photographing is not performed even if the shutter button is released by mistake.
