Abstract

PURPOSE:To freely alter an aspect ratio of a screen by manipulating concealing plates from outside. CONSTITUTION:Since a sliding nob 11 is slid in a A direction, towards a lens, and levers 9 and 9' are also pulled in the direction, sliders 6 and 6' are moved towards the center, and pins 8 and 8' are also moved towards the center along with the sliders 6 and 6'. Then, sprints 12 and 12' are opened to move the screens 1 and 1' vertically, and a surface shown by oblique lines becomes a photographing plane. Thus, the entire surface corresponding to the normal photographing range of the film surface is irradiated with the light from the lens. When the nob 11 is slid in a B direction, towards a film, the levers 9 and 9' are opened laterally, and the sliders 6 and 6' are also moved outwards. Attending on the movements of the pins 8 and 8' outwards, the springs 12 and 12' are pulled, and the plates 1 and 1' are moved towards the center. Consequently, a part of the inside area from the top and bottom of the film surface facing each other is hidden, and panoramic photographing is ready. Thus, the aspect ratio of the screen can be freely altered.

FIG. 2 shows a second embodiment. Components having the same functions as those described above are given the same reference numerals and their explanations will be omitted. Figure 2 (a
) indicates a normal shooting condition in which the entire surface of the film in the normal shooting range is illuminated by the light from the lens.

As shown in the figure, both ends 2 and 2' of the hidden plates l and 1' are pipe-shaped, and are penetrated by the shaft 20.
It is arranged to be slidable in the axial direction of the shaft 20. They are biased upward and downward by coil springs 21, respectively. The shaft 22 arranged parallel to the hidden plate 1 has pipe parts 23a and 23a' connected to the shaft 22.
A slider 23.23° is attached to the end portion of the lever part 23b, 23b'' which has a gourd portion 23c, 23c'' at the tip thereof and is attached in an L-shape to the end thereof. And the stoppers 2 at the respective outer ends of the pipe parts 23a, 23a' of the slider 23.23° and at both ends of the shaft 22.
The sliders 23 and 23 are urged inward by coil springs 24 between the sliders 2a and 22b.

The rotating knob 25 that can be operated from outside the camera is the cam 25a.
The gourd is formed integrally with the gourd and rotates around a shaft 25b. When the rotation knob 25 is rotated clockwise from the current position, the cam 25a moves between the pipe portions 23a and 2 of the slider 23° and 23°.
3a' respectively expand outward against the elasticity of the coil spring 24. On the other hand, between the extensions 2a of both ends 2.2' of the hidden plate 1.1', the holes 2b of 2a', and 2b, there is a bin 26, a bin part 23c of the slider 23.23',
or 230' and via bin 26 lobe 2
7 is being stretched.

The operation is explained as follows.
In FIG. 2(a), the light entering from the lens hits the entire normal photographing range of the film, and the shaded area is the photographing surface.

Next, FIG. 2(b) shows a state in which the rotary knob 25 is rotated 90 degrees clockwise. When the slider 23.23' is opened outward on the left and right sides by the cam 25a integrated with the rotation knob 25 and the lobe 27 is pulled left and right by the pins 23c and 23c', the coil spring 21 is compressed and the hidden plate 1. 1 is drawn to the center, and as shown in the figure, part of the top and bottom of the film surface in the normal shooting range is hidden by the plate 1.1.
The shaded area becomes the photographing surface and becomes a panoramic photographing state.

In this embodiment, instead of the lobe 27, springs 12 and 12° may be used as in the first embodiment (paper omitted in the diagram at X). The stopper shall be provided in the same manner as in FIG.

A third embodiment using a solenoid is shown in FIG. 3, and its structure and operation will be explained.

As shown in FIG. 3(a), the hidden plates 31 and 31 are rotatably held by the shaft 32. In the current state where no current is flowing through the solenoid 34 due to the stress of the spring 33, each lens is rotated as shown in the figure. It has been rotated to the side, and the entire normal shooting range of the film is illuminated by the light from the lens, making it a normal shooting condition. In the figure, 35 is a concealed plate drive lever that is directly connected to the solenoid 34.

In FIG. 3(b), when current flows through the solenoid 34 and the movable pieces of the solenoid are drawn inward, the force of the hidden plate drive lever 35 (the upper side moves downward and the lower side moves upward. At this time, the hidden plate 31 , 31' is a hidden plate driving lever 35, and two hidden plates 31.31° each hide a part of the upper and lower parts of the normal shooting range of the 90-degree rotation film, and the light from the lens reaches only the shaded area in the figure. The camera enters panoramic shooting mode.

In this embodiment, the hidden plate was driven using a solenoid.The switching may be performed manually from outside the camera device using a coupling mechanism without using a solenoid. It shall be installed outside the camera.

FIG. 4 shows a fourth embodiment in which a hidden plate is moved up and down by rotational force using a motor, and its structure and operation will be explained.

As shown in Fig. 4(a), the gear 4 is directly connected to the motor 4I.
2 rotates gear 44.44' via intermediate gear 43.43°. The gear 44.44" has a spindle 4 with screw grooves in which the directions of the threads are opposite to each other with the upper and lower middle as the border.
5.45' are directly connected to each other, and the upper hidden plate 46 has female thread grooves cut into the inner surface of the cylindrical portion 47 at both ends that match the thread grooves above the support shaft 45.45'. On the other hand, the lower hidden plate 46' has a female thread groove cut into the inner surface of the cylindrical portion 47' at both ends thereof, which matches the thread groove below the support shaft 45.45. At present, the motor 41 and each gear have finished rotating in the direction of the arrow in the figure, and the hidden plates 46 and 46' have finished moving upward and downward, respectively, and the film is normally photographed as shown in the shaded area. The light from the lens hits the entire area, making it a normal shooting condition.

Next, in FIG. 4(b), when the motor 41 rotates counterclockwise and each gear rotates in the direction of the arrow, the support shaft 45.
45'' rotates in the opposite direction to the previous one, so the hidden plate 4
6.46" move in the direction opposite to the previous one, approaching each other. At this time, by controlling the rotation amount of the motor 41, a force to provide some kind of stopper is applied to the hidden plate 46.4.
A stopping position of 6° can be determined.

Therefore, the hidden board 46. and 46°, parts of the upper and lower parts of the film's normal shooting range are hidden as shown in the figure, and only the shaded area is captured, resulting in a panoramic shooting state.

In this case as well, a changeover switch (not shown) is provided outside the camera as an operating means.

As described above, the configurations of this embodiment allow for normal photography and panoramic photography to be changed arbitrarily depending on the photographer's intention and the subject to be photographed, even after loading the film and starting photography.

The movement of the hidden plate in the above embodiment is different from the normal shooting range.
The force explained in the two steps with the panoramic shooting range <,, except for the third embodiment, all of them can be stopped at an appropriate position in the middle and continued, or the aspect ratio of the shooting range can be changed in stages. It's good.

In addition, it is possible to change the focal length by moving part of the configuration of the photographing lens in conjunction with the mechanism of the above embodiment or the electrical operation, thereby expanding the photographable angle of view and further increasing the panoramic photographing effect. You can also do it.

In addition, in conjunction with the mechanism of the above embodiment or electrical operation, the viewfinder display range of the camera can be changed depending on the normal camera L or panoramic shooting. You can also hide part of the image and clearly indicate the area that will be photographed (
− Furthermore, panoramic images are generally made of horizontally oriented paper, but can also be made vertically if necessary.

As mentioned above, various examples of the driving means for driving the hidden plate have been described (the driving means is not limited to those described above, and various modifications are possible.

In summary, by having two hidden plates, a driving means for changing the position or angle of the hidden plates through a mechanism or power, and an operating means for operating this driving means from outside the camera lid. The hidden plate can be moved by the operating means via the driving means, and the aspect ratio of the photographed image can be changed from outside the camera.

The above invention applies not only to still cameras, but also to movie cameras,
It is also applicable to video cameras.

As described in detail, the camera device of the present invention allows the hidden plate to be operated from the outside of the camera device, so depending on the photographer's intention or the subject, the shooting screen may change even during shooting. It is possible to provide a camera device that can freely change the aspect ratio of the camera and use either normal photography or panoramic photography with a single touch, and has great practical effects.
