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.

Considering that such a slide case is provided in an inexpensive camera, most of inexpensive cameras are of a type in which a film is manually wound up.
It is necessary to provide an opening on the back of the slide case to expose a film winding member provided outside the body main body.

[0007]

However, it is difficult to operate the film winding member through the opening on the back of the slide case as described above. This is because most film winding members are of a lever type or a dial type, which are provided on a surface one step depressed from the contour of the body main body and do not protrude from the opening of the slide case. For this reason, it is difficult to operate the slide case since the rear side of the slide case is recessed so that the operation member is slightly exposed from the opening.

In the case where the film winding member is provided so as to protrude from the opening of the slide case, it is necessary to lengthen the opening according to the amount of movement of the slide case. Such a large opening is not desirable because it is not desirable in the design of the camera and its role as a protective case is reduced.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its object to provide a camera having a slide-type protective cover and capable of easily operating a manual film winding member.

[0010]

In order to solve the above-mentioned problems, a camera according to the present invention has a built-in shutter mechanism and a film winding prevention mechanism, and a body body provided with a photographic lens exposed to the outside. An outer case movably covered on the outer surface of the body body between a non-use position covering a range including the photographing lens from a side surface on the grip side and a photographing position protruding toward the grip side and exposing the photographing lens. And a film winding-up mechanism built in the body, linked to an external outer case through an opening, and winding up the photographic film by transmitting the moving force of the outer case. . According to this, if the outer case is moved between the non-use position and the photographing position, the film can be easily wound up.

According to the second aspect of the present invention, there is provided means for converting the reciprocating driving force obtained from the outer case into a one-way driving force, and the photographic film is wound by utilizing the moving force of the outer case in both directions. This is a film winding mechanism.

As the photographic film cartridge 44 housed in the unit body 11, for example, a photographic film cartridge corresponding to the IX240 film cartridge is used. Note that 135
A type of photographic film cartridge may be used. The photographic film cartridge 44 includes a photographic film 51.
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 optical path, is formed at 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 lids 21 and 57 are provided in a lower part of the rear cover 31 in a pull-top manner. In addition,
A notch 21a for inserting a driver is formed in the bottom lid 21 of the cartridge chamber.

A film winding mechanism 58 including a winding gear 14 is provided above the cartridge chamber 55. The rack plate 30 enters the inside of the unit body 11 through the horizontally long opening 22 provided in the rear cover 41 and meshes with the hoisting gear 14. In addition to the opening 22, the rear cover 41 is provided with a finder eyepiece window 60 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 FIGS. 7 and 8, the film winding mechanism 58 includes a leaf spring 62, a one-way rotating plate 63, a winding gear 14, an intermediate member 64, a felt plate 65, and
The rack plate 30 is composed of a spool drive plate 66 and the like.
meshes with a.

The hoisting gear 14 has an internal gear 1
4b is formed. Three planetary gears 67 to 69 mesh with the internal gear 14b. A sun gear 64a formed on the intermediate member 64 meshes with these planetary gears 67 to 69. The internal gear 14b, the planetary gears 67 to 69, and the sun gear 64a constitute a planetary gear mechanism.

The one-way rotating plate 63 includes planetary gears 67 to 6.
9 are provided respectively, and the planetary gear 67
６９69 revolutions are transmitted. This one-way rotating plate 63
Are provided with a large number of ratchet claws 63a. A plurality of claws 62a provided on the leaf spring 62 are engaged with these ratchet claws 63a. The leaf spring 62 is fixedly provided on the inner wall of the front cover 40, and in the rotation direction of the one-way rotating plate 63 in the counterclockwise direction shown in FIG. Is allowed, and rotation in the opposite direction is prevented.

The one-way rotating plate 63 has a support cylinder 63b formed at the center of rotation. A support cylinder 64b provided at the center of rotation of the intermediate member 64 is engaged with the support cylinder 63b to rotatably support the intermediate member 64. Rotational force is transmitted between the support cylinders 63b and 64b by a frictional force generated at a contact portion between the support cylinders 63b and 64b.

When the internal gear 14b rotates counterclockwise, the planetary gears 67 to 69 revolve in the same direction while rotating in the counterclockwise direction. This revolving force is transmitted to the one-way rotating plate 63, the one-way rotating plate 63 rotates counterclockwise, and the counterclockwise rotation is transmitted to the sun gear 64a by the frictional force of the support cylinders 63b and 64b. You. At this time,
Since the one-way rotating plate 63 rotates together with the internal gear 14b, the planetary gears 67 to 69 stop rotating.

On the other hand, when the internal gear 14b rotates clockwise, the planetary gears 67 to 69 rotate clockwise and try to revolve in the same direction. Since the planetary gears 67 to 69 are prevented from revolving because they are blocked by the ratchet pawls 63a and the pawls 62a, the sun gear 64a is rotated counterclockwise by the rotation force of the planetary gears 67 to 69.

The intermediate member 64 having the sun gear 64a is
A support tube 66a provided at the center of rotation of the spool drive plate 66 is engaged with the inside of the support tube 64b, and is rotatably supported by the spool drive plate 66. On the spool drive plate 66,
Gear plate 66b having the same center of rotation under support cylinder 66a
Is provided. A fork 66c is provided on the lower surface of the gear plate 66b with the same center of rotation. The fork 66c is connected to the opening 5 provided in the upper part of the cartridge chamber 55.
5a (see FIG. 8), and is rotatably supported at the edge thereof.
The tip enters the inside and is engaged with the spool 52.

The intermediate member 64 is provided with a horizontal disk 64c below the support cylinder 64b. This horizontal disk 6
A felt plate 65 is inserted between the gear 4c and the gear plate 66b. The above-described leaf spring 62 urges the intermediate member 64 toward the spool drive plate 66 via the one-way rotating plate 63. As a result, the felt plate 65 is
The rotation of the intermediate member 64 is transmitted to the spool drive plate 66 using the frictional force generated at the contact portion between the gear c and the gear plate 66b,
By rotating the spool 52 in the film winding direction (the direction of the arrow shown in the figure), the photographed film 51 having been photographed is wound into the cartridge 53. And the gear plate 66
When the film unwinding mechanism is activated, the unwinding piece constituting the film unwinding mechanism meshes with the gear portion b to prevent the rotation of the spool drive plate 66.

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 21 and 57 are closed, and the assembly of the unit main body 11 is completed. At this time, the shutter mechanism is in an uncharged state,
Assembled without film winding.

Next, the outer case 12 is inserted from the end of the grip portion 20, and the convex portion 25 is engaged with the elongated hole 24. 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 23 covers the photographing lens 13 to completely cover the range from the grip portion 20 to the photographing lens 13 as shown in FIG. At this time, since the rack plate 30 meshes with the tooth row 14a of the hoisting gear 14, and the hoisting gear 14 rotates clockwise in FIG. 9, the film is wound up. Here, in this embodiment, the film winding mechanism 58 is a speed reduction mechanism, and the rotation amount of the spool 52 for winding the film for one frame is rotated by one forward or backward movement of the rack plate 30. The rotation amount is larger than the rotation amount of the spool 52. For this reason,
Even when the outer case 12 is attached, the film is not stopped.

When the outer case 12 is attached, the taking lens 13, the finder objective window 48, the shutter button 19,
The viewfinder eyepiece window 60 and the charging completion display window 29
The unit case 11 is completely covered by the outer case 12, and dust or sand or foreign matter is removed from the gaps between these openings during transportation or the like.
To prevent the film unit 10 from breaking down or affecting the photographic properties. Further, since the shutter button 19 is hidden, even if the shutter button 19 is pressed by any force during transportation, the pressing of the shutter button 19 by the outer case 12 is prevented, so that the shutter mechanism does not operate. .

When taking a picture, the film is wound up. Film winding is performed by reciprocating the outer case 12. Therefore, the photographer slides the outer case 12 between the unused position and the photographing position. Thus, the rack plate 30 rotates the hoisting gear 14.

When the hoisting gear 14 rotates clockwise in FIG. 9, the internal gear 14b rotates
69 is rotated clockwise. Thereby, the planetary gear 6
7 to 69 try to revolve clockwise, but since the rotation in the revolving direction is blocked by the ratchet pawl 63a and pawl 62a of the one-way rotating plate 63, the planetary gears 67 to 69
Is stopped, so that the sun gear 64a is rotated counterclockwise by the rotation force of the planetary gears 67 to 69. The rotation of the sun gear 64a in the counterclockwise direction is
5 to the spool drive plate 66, which rotates the spool 52 in the film winding direction.

When the hoisting gear 14 rotates in the counterclockwise direction in FIG. 9, the internal gear 14b rotates the planetary gears 67 to 69 in a counterclockwise direction, and the planetary gears 67 to 69 rotate.
69 revolves counterclockwise. This revolving force is transmitted to the one-way rotating plate 63, the one-way rotating plate 63 rotates counterclockwise, and the counterclockwise rotation is transmitted to the sun gear 64a by the frictional force of the support cylinders 63b and 64b. You. The rotation of the sun gear 64a in the counterclockwise direction is
Is transmitted to the spool driving plate 66, and the spool driving plate 66 rotates the spool 52 in the film winding direction.

As described above, since the spool 52 can be rotated in the film winding direction by utilizing the sliding movement force of the outer case 12 in both directions, the film can be wound easily and quickly.

As shown in FIG. 9, the shutter mechanism, film winding mechanism, film counter mechanism, and the like 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 photographic film 51 is attached to the sprocket 73.
The photographic film 51 is rotated by a predetermined amount when the photographic film 51 is transported 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 enters the recess 77a, and the locking lever 75 rotates clockwise. At this time, the rotation of the sprocket 73 is prevented. At this time, the locking lever 75 is at the winding stop position.

The locking lever 75 is provided with a locking piece 75b that meshes with the gear 66b on the outer periphery of the spool driving plate 66 when the locking lever 75 is at the locking position. Therefore, when the locking lever 75 rotates to the winding position, the winding piece 75b prevents the rotation of the spool driving plate 66. The rotation of the sprocket 73 in response to the transfer of the film for one frame is transmitted to a gear 81 provided concentrically with the sprocket 73, and the gear 81 advances the number display plate 78 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.

As described above, when the photographic film 51 is wound up by the length of one frame, the rotation of the spool drive plate 66 is stopped by the film winding stop mechanism, and the shutter mechanism is charged during this time. Here, there are cases where the outer case 12 is not at the photographing position at the time when the rotation of the spool driving plate 66 is stopped. Therefore, an operation of sliding the outer case 12 to the photographing position after the sliding operation of the outer case 12 for the film winding operation is completed is required.

Therefore, after the rotation of the spool driving plate 66 is stopped, the outer case 1
Even if the slide movement operation of 2 is performed, the contact portion between the felt plate 65 and the horizontal disk 64c or the gear plate 66b, or
Slip is performed at a contact portion with the support cylinders 63b and 64b. In addition, the photographer can sense that a load is applied to the movement of the outer case 12 due to the slip, and that the film winding is completed by the load.

When the outer case 12 is moved to the photographing position, the outer case 12 protrudes toward the grip 20 of the unit body 11. 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. At this time, the taking lens 13, the finder objective window 48, the shutter button 19, the finder eyepiece window 60, and the charging completion display window 29 are connected to the outer case 12.
Completely exposed from

When the shutter button 19 is depressed, the rod provided on the lower surface of the shutter button 19 pushes the locking lever 75 toward the unlocking position (counterclockwise) as is well known. At this time, the engagement between the falling piece 75c and the rising piece 74b is released, and the shutter drive lever 74 is released.
Is instantaneously rotated toward the release completion position by the bias of the spring 82. During this time, the kicking arm 74c provided on the shutter drive lever 74 is connected to one end 7 of the shutter blade 79.
Kick off 9a. 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 unrolling release position engage with each other, and the shutter driving lever 74 is moved to the locking lever 75. In the unwrapped position. When the locking lever 75 rotates to the unwrapping release position, the locking piece 75b is retracted from the gear 66b, so that the next film winding operation is permitted.

When not in use, the outer case 12 is slid to the 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. At this time, the rack plate 30 rotates the hoisting gear 14, but the spool 52 has a length corresponding to one frame.
There is no problem because it is not enough to rotate. In addition, at both the photographing position and the unused position of the outer case 12, only the photographing number display window 18 is exposed, so that the photographing number can be quickly confirmed. 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 21 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 21 can be opened in the same manner as in the related art. At this time, the area of the outer case 12 corresponding to the bottom cover 21 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 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, and 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 photographic film 51 has a length of one frame.
The amount of sliding movement of the outer case 12 for winding up is, for example, one reciprocation is appropriate from the viewpoint of manual operation.
Therefore, it is desirable to set the number of teeth of each gear of the film wind-up mechanism 58 so as to achieve the rotation ratio of this order. However, the spool 52 that winds up the film
Is different between the first frame and the last frame because the photo film 51 is wound around and becomes thick. For this reason, it is meaningless to adjust the slide movement amount of the outer case 12 to the extent that the photographic film 51 is wound up by the length of one frame in advance. Therefore, after the film winding stop is activated, the winding drive is transmitted to the spool 52. A mechanism to slip so as not to be required is always required.

In the above embodiment, the planetary gear mechanism is used to take out the moving force in one direction of the outer case 12 from the revolution of the planetary gears and take out the moving force in the other direction from the sun gear, so that the moving force in the film winding direction is obtained. Although the driving force is converted, the present invention is not limited to this mechanism, and for example, a reciprocating sliding element rotating mechanism called a piston or a crank mechanism may be used.

The above-described film winding mechanism 58 uses the reciprocating motion of the outer case 12 to wind up the film. . In this case,
The rotation when the outer case 12 moves to the other
2, a slip means that does not transmit to the motor 2 is required. Although the meshing position between the rack plate 30 and the hoisting gear 14 is on the rear side, the present invention is not limited to this, and the rack plate 30 is provided on the front side and the hoisting gear 14
And the front side.

Further, the guide for sliding the outer case 12 is provided by the opening 24 and the convex portion 25. However, the present invention is not limited to this. The side of the main body 11 may be a concave portion, or the movement of the outer case 12 may be guided by using an engagement area between the rack plate 30 and the opening 22 into which the rack plate 30 enters. In the latter case, the opening 24 and the projection 25 described above can be omitted.

[0053]

As described above, according to the present invention, since the film winding mechanism for winding the photographic film by transmitting the moving force of the outer case is provided, the outer case can be moved between the non-use position and the photographing position. The film can be wound up automatically by simply moving between them, and the winding operation becomes simple. According to the second aspect of the present invention, since the reciprocating driving force obtained from the outer case is provided with a means for converting the reciprocating driving force into a one-way driving force, the photographic film is wound using the moving force of the outer case in both directions. Film can be quickly wound up.
