The present invention relates to a shutter that can continuously photograph a subject's dynamic posture in one frame, and in particular, by configuring the holes of the light shielding plate where the holes drilled in several rotating gears are sequentially and instantaneously coincident with each other. The present invention relates to a motion-divided continuous shooting shutter having a suitable configuration for continuously photographing moving motions.

The shutter of the conventional general camera has a film exposure structure mainly by a wing, and the shutter movement method has a structure that opens and closes in the center of the entrance furnace and moves from the upper side to the lower side or the left side to the right side of the entrance furnace. There were things with a structure that made the movement.

These conventional shutters are configured to open and close the entrance path where light enters, so that the exposure state of the film cannot be partitioned, so when a print is made, a scene of static operation is developed in one frame, and the moving motion is continuously shot. In this case, it was possible to use a photographing technique to quickly transfer the film and press the shutter by mechanical motion.

However, in the case of such conventional continuous shooting has been pointed out that the biggest consumption is that the film can not be taken a lot because the consumption of film.

The present invention has been made in view of the conventional problem, and the drive gear is rotated by the release of the shutter button so that the moving motion on one frame is divided, and several driving gears engaged with the rotating gear are drilled on the gear. It is intended to provide a configuration in which exposure is sequentially performed in a plurality of places on a frame by sequentially forming a state in which a hole is sequentially aligned with a fixed aperture that is drilled on a shutter base.

Each of the exposure control unit 120 formed of a shutter cover 115 formed with the through holes 112 and 112a .. l12n formed to protrude through the 111 and the same function as the above-described through holes. It will be equipped with.

With such a configuration, the present invention is to take a picture by pulling a film outside lever installed on the outside of the main body of the camera as in a conventional picture taking method, and then pressing a release button. One frame range at a time is divided into at least several small frames to show a developed state.

The frame formed by dividing the above one frame range into several small units is formed by a shutter operation that sequentially opens and closes the lens path along the position of each divided frame. It is possible to expose the film by distinguishing the movement of the subject from the film even when the subject is moving.

Therefore, it is possible to record the moving state of the subject on one frame, and the moving state of the subject is photographed by dividing the film into the film. You can expect it by tweaking.

It is a generally known driving state that a film cut is loaded in an exposure chamber by moving the film winding lever which is not shown in a predetermined direction.

When the above film supply operation is performed, the gears connected to the sprocket or the winding motor (not shown) The locking piece 101 of the flat plate is engaged. The plate plate 105 is moved in the left direction, that is, in the direction of the release button 117.

Above Before the plate plate 105 moves, the second light shielding plate 81 is moved to the left by the gear piece 82 engaged with the gear of the film winding part (not shown), thereby penetrating through the shutter base 70. (73, 73a..73n) to block the action.

The above blocking operation is performed only until the supply operation of the film is completed, and when the film supply operation is completed, the gear piece 82 of the second light shielding plate 81 reaches the concave groove of the film winding part gear (not shown). The second light blocking plate 81 transmits the elastic force of the coil spring 84 to be contracted and returns to the original position by being not engaged with and not being engaged.

The second light shielding plate 81 immediately returns to the completion of movement by the small holes 5, 5a, 5b, and 5C of the shutter gear portion and the staggered through holes 88 and 89 of the first light blocking plate 85. This is to be inconsistent during loading.

Above Since the locking plate piece 86 of the first light blocking plate 85 is caught by the lower guide protrusion 102 in the state where the celtic plate 105 moves, and the driving gear 2 is engaged with the upper flat difference 103. The first light blocking plate 85 moves to the left side, and the gears of the shutter gear unit 40 move to the position to block the penetration hole while simultaneously rotating clockwise and counterclockwise.

At the position where the plate plate 105 is completely moved, the hook 118 of the release button 117 is caught by the jaw of the flat car 103, so that it is caught in the state of receiving the elasticity of the coil spring 84 '. The flat jaw of the first light blocking plate 85 is caught by the stopper 90.

Above In the state where the plate plate 105 is caught, the supply of the film is completed and the through holes 21 and 21a formed in the holder 20, the second light shielding plate 81, the shutter base 70, and the shutter cover 65 and 115. .21n) (63,63a..63n) (73,73a..73n) (83,83a..83n) (112,112a..l12n) and the transmission hole of the shutter gear part 40 and the first light shield plate 85 (88, 88a..88n) can be in an inconsistent position, preventing the film from being unnecessarily exposed.

In the above state, the user adjusts the lens of the camera to the subject, takes a shooting posture, and then presses a release button in a conventional manner.

When the release button of the camera is pressed, the hook 118 of the release button 117 The locking state of the tread plate 105 is released and at the same time by the return action of the torsion spring 116 of the hook The plate plate 105 performs an elastic return movement in the first direction and simultaneously presses the rear end of the stopper 90 by the guide protrusion 102 to release the locking of the first light blocking plate 85. Therefore, the first light blocking plate 85 also has a return action.

And The return movement of the plate plate 105 serves to rotate the drive gear 2 meshed with the flat tooth 105, and to rotate the drive gear 2. The gears of the speed adjusting part 50 and the gears of the shutter gear part 40 including the idle gears 3 engaged with each other by the rotation of the rotator are all rotated so that the through holes 88 and 89 of the first light blocking plate 85 are rotated. ) And the small holes 5, 5a, 5b, and 5c of the shutter gears 4, 4a, 4b, and 4c are through holes 73, 73a .. 73n of the second light blocking plate 81 and the shutter base 70 (83, 83a..83n), the exposure is effected.

The above exposure is not performed at one time but is sequentially performed in several transmission holes from the start of driving of the shutter gear to the completion of driving.

The state exposed sequentially will be described in more detail.

The through holes 73, 73a .. 73n, which are vertically and horizontally drilled through the shutter base 70, are disposed at predetermined uniform intervals and are transmitted through the first light blocking plate 85 that is moved by the shutter plate 105. (88, 89) is also vertically and horizontally drilled at predetermined uniform intervals, but the upper and lower positions do not coincide and staggered so that when the film supply is completed, the penetration holes 88 and 89 of the first light blocking plate 85 are located at the lower side. Only the through-holes are in agreement with the lower through-holes of the shutter base 70, and the upper through-holes coincide when the release button 117 is pressed to release the locking of the first light blocking plate 85.

In addition, the above-mentioned penetration holes are formed in the gap between the upper and lower shutter gears of the upper and lower shutter gears; The small holes of the shutter gears are bored in the space between the centers, and the small holes of the shutter gears are excessive in the above-mentioned transmission holes during rotation.

As such, when the time required to coincide with the transmission hole is different, the natural exposure is sequentially performed.

In the sequential exposure described above, the release button 117 is pressed while the film supply is completed. When the locking plate 105 is released, the torsion spring The plate plate 105 is moved so that the pair of shutter gears 4, 4a, 4b and 4c rotate by the idle gear 3 at the same time.

When the shutter gears 4, 4a, 4b and 4c rotate, a small hole 5a drilled in the lower shutter gear 4a coincides with the first through hole at the bottom to achieve the first exaggeration of exaggeration. The small hole 5a is rotated to the lower second through hole to achieve a second exposure state when coincided.

After the second exposure state, when the small hole 5c drilled in the shutter gear 4c located on the lower right side coincides with the lower third through hole, the third exposure state is achieved. Then, the small hole 4c is moved to the next position. When it coincides with the fourth through hole, the fourth exposure state is achieved.

When the fourth exposure state is achieved Since the guide protrusion 102 of the plate plate 105 reaches and pushes the stopper 90, the locking state of the first light shielding plate 85 is released, and thus the penetration holes at the lower ends of the first light blocking plate 85 are sequentially blocked. And the through holes at the upper end that are blocked are coincident with the through holes of the shutter base, and then the small holes 5 drilled through the shutter gear 4 at the upper left coincide with the first through holes at the upper end. The first exposure state is achieved.

After the fifth exposure, the continuous rotation of the upper left shutter gear 4 causes the small hole 5 to coincide with the second through hole next to the sixth exposure state, and then the upper right shutter gear 4b. The small hole 5b drilled in the) is in a state coinciding with the third through hole in the upper end to form the seventh exposure state, and then the small hole 5b of the shutter gear 4b coincides with the upper fourth through hole in continuous rotation. To achieve the eighth exposure state.

The exposure state can be increased or decreased by four continuous yarns, eight continuous yarns, 12 continuous yarns, 16 continuous yarns, etc. in accordance with the above-described increase and decrease of the number of exposure-acid transmission holes and shutter gears.

To return when pressing the release button as above With the movement of the plate The rotation of the driving gear engaged with the plate plate causes the several shutter gears, the first light blocking plate, and the plurality of transmission holes drilled in the second light blocking plate to coincide with each other sequentially so that the exposure is sequentially performed at one or more frames of the film. .

This is the same shooting condition as shooting a single motion by dividing a film on a film with a single shutter press. Therefore, the present invention can shoot multiple motions with a single press of the shutter, so that not only the existing still subjects can be photographed but also the subjects are sequentially photographed in a continuous state even when photographing a moving subject. Then, the operation of photographing the continuous division motion on one frame is performed.

As described above, the present invention can photograph a subject several times on one frame due to a state in which light passages are sequentially opened and closed by an operation of normally pressing a release button, thereby photographing a moving subject. Since the movement of the subject is taken as a sorting operation, there is an advantage that it is very convenient to take a picture of a moving subject, and the movement of a moving subject is expressed as a sorting operation in a printed state, so that the continuous sorting operation can be viewed on one frame. There is an advantage that can be.

This shooting state is mainly capable of efficiently photographing movements of leisure, sports games, automobiles, and animals, and its structure is simple and easy to manufacture and assemble. There is a feature that can be applied.
