Abstract

PROBLEM TO BE SOLVED: To set the feed amount of every photographic frame of film nearly constant with simple constitution and to prevent the film from being wastefully used by making the turning amount of a turning member, which is a specified amount, different for every photographic frame of the film in a method for controlling feeding film for a camera. SOLUTION: A winding lever 21 being a winding operation member is integrated with a shaft 22 and the shaft 22 is freely turned by a bearing formed on a bottom plate 16. The turning member 23 is fixed at one end of the shaft 22 and is provided with a shutter charge cam 23b being a shutter charge member. The turning amount of the cam 23b allowed for every photographic frame is made different. By such a method, the winding operation of the winding operation member 21 is inhibited in accordance with the turning amount of the member 23 different by every photographing, so that the feed amount of the film is kept constant even when a winding spool gets gradually thick because of winding the film as photographing progresses.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera film feed control method, a camera film feed mechanism, a camera shutter charging method, and a camera shutter charging mechanism. The present invention relates to a film feeding control method, a film feeding control mechanism, a shutter charging method, and a shutter charging mechanism in a film unit.

[0002]

2. Description of the Related Art Conventionally, a lens-equipped film unit in which an unexposed film is built in at the manufacturing stage has been widely used. In recent years, in order to improve the quality of photographs obtained by this lens-equipped film unit, It has been proposed to incorporate a brownie film.

[0003] By the way, the Brownie film is a conventional J1.
Since no perforation is formed unlike 35 film and the like, a mechanism that controls the feed amount of one frame by using the rotation of a sprocket that engages with the perforation and follows the film as in a conventional film unit with a lens. Can not be adopted.

In order to solve this problem, a cam member is provided which rotates in conjunction with the operation of the hoisting knob. Each time the cam member rotates once, a shutter is charged, and rotation of the hoisting knob is prohibited. Thus, a configuration for controlling the feeding of one frame has been proposed (JP-A-10-20450).

[0005]

According to the above arrangement,
Each time the hoisting knob is rotated by a certain amount, the winding is stopped. However, since the winding spool gradually becomes thicker as the shooting progresses, even if the amount of rotation of the winding knob is constant, the number of shooting frames in the latter half of the amount of film fed in the early stage The amount of film fed is larger. For this reason, as the number of frames to be photographed increases, the frame interval becomes unnecessarily wide, and the film is wasted, and the number of frames to be photographed cannot be increased.

In order to solve this problem, for example, it is conceivable to provide a roller member that rotates in synchronization with the actual feeding of the film, and to stop the winding in conjunction with the rotation of the roller member. However, in order to reliably rotate the roller member in conjunction with the film without perforation, a highly accurate and complicated structure is required, and the film unit with a lens which requires an inexpensive and simple structure is required. Is not preferred. In addition, since it is desired to make the operation of the photographer as simple as possible in the film unit with the lens, it is required that the shutter charge be completed when the winding operation by the operator is completed. When the roller member is used as described above, it is conceivable that the shutter charge is performed in conjunction with the rotation of the roller member, or a shutter charge mechanism that is linked with the winding operation is provided separately from the roller member. However, in either configuration, the mechanism becomes complicated, which is not preferable for use in a film unit with a lens.

An object of the present invention is to provide a camera using a film without perforation, in which film feeding and shutter charging are accurate and simple in structure, and a film feeding amount per frame is substantially constant. The present invention is to provide a camera film feed control method and a film feed control mechanism capable of preventing the film from being wasted, and in particular, a Broni film without perforation is built in a manufacturing stage in advance. Suitable for film unit with lens.

Another object of the present invention is to provide a camera using a film without perforation.
It is an object of the present invention to provide a camera shutter charging method and a shutter charging mechanism capable of easily and reliably charging a shutter, and is particularly suitable for a film unit with a lens in which a brownie film without perforation is built in at a manufacturing stage in advance.

The hoisting lever 21 serving as a hoisting operation member is
The shaft 22 is rotatable by a bearing formed on the main plate 16. A rotating member 23 is fixed to one end of the shaft 22. The rotating member 23 has a shutter charge cam 2 serving as a shutter charging member.
The shutter charge cam 23b is provided with a different amount of rotation for each photographing frame. The shutter charge cam 23b rotates in conjunction with the hoisting operation of the hoisting operation member 21 to charge the shutter. Note that the shutter charge 23b is
It may be structured to rotate in conjunction with the rotation of.

An urging member 24, which is an urging means for urging the hoisting operation member in a direction opposite to the film feeding direction, is a torsion spring and has a pin 21 provided at one end on the hoisting lever 21.
a and the other end is provided on a pin 16a provided on the main plate 16.
It is being applied to The urging member 24 urges the hoisting lever 21 clockwise (arrow) in FIG. Therefore, when the hand is released from the hoisting lever 21 after the hoisting operation,
The hoisting lever 21 hits a stopper member 25 provided on the main plate 16 and stops. At the same time, this stopper member 2
Reference numeral 5 denotes a structure in which when the shutter charge cam is rotated in the direction opposite to the direction of charging the shutter, the rotation of the shutter charge cam returns to the initial position at a predetermined position.

As will be described later, the allowable rotation amount of the winding lever 21 differs for each photographic frame of the film, and decreases as the number of photographic frames of the film increases.

Next, a description will be given of a shutter charging mechanism, a winding prohibiting mechanism (winding stopping mechanism) of the winding operation member, and the like. The shutter charge lever 31 and the stop lever 34 are coaxial with the support shaft 33, and the shutter charge lever 31 is located below the stop lever 34 and is rotatably mounted on the unit body 10. A torsion spring 32 is provided below the shutter charge lever 31. One arm 32a of the torsion spring 32 is engaged with the first arm 31a of the shutter charge lever 31, and the other arm is a pin 36. Is pressed against.

Accordingly, the shutter charge lever 31 is urged counterclockwise by the torsion spring 32. Another torsion spring 35 is hung between the stop lever 34 and a pin 31e provided on the shutter charge lever 31 to bias the stop lever 34 clockwise with respect to the shutter charge lever 31.

A stop claw 37 for stopping the hoisting lever 21 is rotatably supported on a support shaft 38 so as to be rotatable.
9 urges in a clockwise direction with a weak urging force. The stop claw 37 has a tip end of an extension 32c extending from the bent portion of the torsion spring 32 engaged with the vicinity of the claw of the stop claw 37, and urges the stop claw 37 clockwise.

Here, the operation of the shutter charge will be described. When the hoisting lever 21 is operated in the counterclockwise direction, the rotating member 23 rotates and simultaneously the shutter charge cam 23b.
Rotate in the same direction. This shutter charge cam 23b
Of the shutter charge lever 31 by the rotation of
By pressing b, the shutter charge lever 31 is rotated clockwise by the urging force of the torsion spring 32. Then, the second arm 31c of the shutter charge lever 31
Move over the end 51 of the sector of the shutter that rotates in a plane perpendicular to FIG. In this way, the shutter charge is performed by the shutter charge lever 31.

Before the shutter is charged by the shutter charge lever 31, as shown in FIG. 3, the first arm 37a of the stop claw 37 engages the tip 31d of the third arm of the shutter charge lever 31, The clockwise rotation of the stop claw 37 is prevented. However, when the shutter charge is performed by rotating the shutter charge lever 31 clockwise, the engagement between the distal end portion 31d and the first arm portion 37a of the stop claw 37 is released, and the stop claw 37 is rotated by a torsion spring. The lever 32 is slightly rotated clockwise by the urging force of the extension 32c. However, the first arm portion 37a of the stop claw 37 has a thickness capable of engaging not only with the distal end portion 31d of the third arm portion of the shutter charge lever 31 but also with the step portion 34a of the stop lever 34. Therefore, after the distal end 31 d of the third arm of the shutter charge lever 31 is retracted, the first arm 37 a of the stop claw 37 is engaged with the step 34 a of the stop lever 34. Therefore, the pawl of the stop pawl 37 has not yet engaged the ratchet 28. Subsequently, when the shutter charge cam 23b is rotated by the rotation of the hoisting lever 21, the stop lever 34 is rotated.
Of the torsion spring 35 jumps into the groove 41a of the hoisting prohibition control member 41 having a storage unit in which different rotation amount information is previously stored for each photographing by the urging force of the torsion spring 35, and the stop lever 34 is turned clockwise. To rotate. Then, with the rotation of the stop lever 34, the step 34a also rotates clockwise, so that the first arm 37 of the stop claw 37 with respect to the step 34a.
a is disengaged, the stop claw 37 rotates clockwise, the claw of the stop claw 37 engages with the ratchet 28, and the lifting lever 2
1 is prevented from rotating counterclockwise. At this time, the first arm portion 37a of the stop claw 37 is
1 will be in contact with the side 31d.

As described above, the rotation amount of the rotation member 23 is controlled based on the rotation amount information of the winding inhibition control member 41 (rotation amount control mechanism).

The shutter charge cam 23b rotates the shutter by a predetermined amount to charge the shutter. After the shutter charge is completed, and after the film feeding is completed, the operator releases the hand from the winding lever 21 to rotate clockwise. To return to the initial position shown in FIG.

When the hoisting lever 21 is rotated clockwise by the urging force of the urging member 24 and returns to the initial position, the leading end 31b of the shutter charge lever 31 is in contact with the shutter charge cam 23b. However, since the tip 37a of the first arm of the stop claw 37 prevents the counterclockwise rotation of the shutter charge lever 31 by the torsion spring 32, the shutter charge lever 31 performs shutter charge. Is maintained.

As will be described later, the amount of rotation of the hoisting lever 21 that is allowed varies for each photographing operation. Therefore, the amount of rotation of the shutter charge cam 23b formed on the rotating member 23 is also different for each film photographing frame. Although configured differently,
If the amount of rotation of the shutter charge cam 23b required to complete the shutter charge is A and the amount of rotation of the shutter charge cam 23b that is the smallest for each film frame is B, then A <B. The shutter is reliably charged by the hoisting operation of the hoisting lever 21 in the photographing frame.

Next, a description will be given of a film feed control mechanism, a winding prohibition mechanism, and the like of the camera. The hoisting prohibition mechanism is operated by the hoisting operation member 21 in response to the turning member 23 turning a predetermined amount.
Prohibit the operation of. Hoisting lever 21 serving as a hoisting operation member
, The rotating member 23 integral with the hoisting lever 21 rotates. The feed claw 2 is attached to one end of the rotating member 23.
6 is supported by a shaft 23a, and the feed claw 26 is in contact with a ratchet 28 by a spring 27. When the rotating member 23 rotates, the feed pawl 26 rotates the ratchet 28, and the gear 43 integrated with the ratchet 28 rotates. Then, the gear 74 rotates via the gear 71 and the gear 72. In addition,
The gear 71 and the gear 72 are formed integrally and are rotatable about a shaft 73. Further, the engaging member 1 integral with the gear 74
7 rotates, the film winding spool S2 engaged with the engagement member 17 rotates, and the film F is wound on the film winding spool S2 to feed the film.

When the winding lever 21 is operated in the film winding direction, the film winding spool S2 is rotated by the feed pawl 26 to be in an interlocked state. When returning in the opposite direction to the upward direction, the feeding pawl 26 escapes from the ratchet 28 and enters a non-interlocking state in which film feeding is not performed.

On the other hand, when the gear 43 is rotated by the hoisting operation of the hoisting lever 21, the film winding prohibition control member 41 is rotated via the gears 44, 45 and 46. The gear 44 and the gear 45 are integrally formed and are rotatable by a shaft 47. The gear 46 is the shaft 4
2 makes it rotatable. This hoisting inhibition control member 41 has a plurality of grooves 41a having different pitch amounts on the outer periphery,
The above-described stop lever 34 enters each groove 41a. When the stop lever 34 enters the groove 41a, as described above,
1 is prevented from rotating counterclockwise. The pitch of the groove 41a is gradually reduced in consideration of an increase in the winding diameter of the film winding spool S2 as the number of film shooting frames increases. The winding prohibition control member 41 stores the allowable rotation amount of the hoisting lever 21 based on the interval between the grooves 41a.

Since the pitch of the groove 41a of the winding prohibition control member 41 gradually decreases as the number of frames to be photographed increases, the rotation angle of the winding lever 21 decreases with each photographing. The mechanism is such that the setting of the shutter charge lever 31 is completed within the range of the minimum rotation amount of the upper lever 21.

A display panel 49 for the number of frames to be taken for displaying the number of frames of the film is integrally formed on the upper part of the winding prohibition control member 41, and the index 48 is formed on the front cover 11. . As a result, the winding prohibition control member 41 can be rotated to accumulate the number of frames of the film, and the structure for displaying the number of frames to be photographed can be simplified.

One end of the ratchet 28 is fixed to the unit body 10 and the end of a reverse rotation preventing claw 29 utilizing the elasticity of the resin material is in contact with the ratchet 28 to prevent reverse rotation of the film F in the winding direction.

Next, the release operation will be described. When a release button (not shown) is pressed, a release shaft 37c provided on the back of the release button is moved from the upper surface of FIG.
Is pressed. Since the inclined portion 37 b is inclined in the direction of the hoisting lever 21, the stop claw 37 is rotated counterclockwise by the urging force of the extension portion 32 c of the torsion spring 32.

Then, the first arm portion 37a of the stop claw 37 is retracted from the side portion 31d of the shutter charge lever 31, and the shutter charge lever 31 is rapidly rotated counterclockwise by the urging force of the torsion spring 32. And the second arm 3
1a rapidly hits the end 51 of the sector to open and close the shutter sector.

The first arm 37a of the stop claw 37 is connected to the tip 31d of the third arm of the shutter charge lever 31.
, And the pawl of the stop pawl 37 is separated from the ratchet 28 of the hoisting lever 21, and the hoisting lever 21 becomes rotatable.

[0047]

According to the above configuration, the following effects can be obtained. According to the first and second aspects of the invention,
Since the winding operation of the winding operation member is prohibited in accordance with the amount of rotation of the rotating member which is different for each photographing, the film feeding amount is kept constant even if the winding spool is gradually thickened as the photographing progresses. It becomes possible.

According to the third and fourth aspects of the present invention, the amount of rotation of the rotating member is controlled based on the amount of rotation information that is stored in advance for each photographing operation. , The feeding amount of the film can be kept constant.

According to the present invention, the shutter charge cam can be returned to the initial position by rotating the shutter charge cam in reverse after the winding is completed. Is different, the shutter charge cam can be surely charged without shifting the phase of the shutter charge cam.

According to the eighteenth aspect of the present invention,
Since the amount of rotation required for shutter charging is set smaller than the smallest amount of rotation allowed for each photographing of the shutter charge cam, the amount of rotation of the shutter charge cam differs for each photographing frame. Also, it is possible to reliably complete the shutter charge for all the shooting frames.
