Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application The present invention relates to a camera capable of cropping photography that instructs printing of a predetermined cropping area within a normal print area.

B. Prior Art A so-called panoramic print is known in which a horizontally elongated area (panoramic printing area and trimming area) of a normal film exposure area excluding the upper and lower parts thereof is printed at a larger enlargement magnification than usual. Conventionally, in order to obtain such panoramic prints, cameras are known that are equipped with light shielding members that cover the upper and lower portions of the aperture. That is, during normal photography, the light shielding member is retracted from the aperture, and during panoramic photography, the light shielding member covers the upper and lower portions of the aperture, exposing only the panoramic print area.

C1 Problem to be Solved by the Invention However, if only the panoramic print area is exposed as described above, it is impossible to obtain a normal size print from that frame, which is inconvenient. Therefore,
When shooting panoramas, you can instruct the print operator to expose the entire normal exposure area and print only the panoramic area within that exposure area, but if this instruction is not clearly given, the intended print may not be obtained. There is a risk that it will not be possible.

An object of the present invention is to provide a camera capable of cropping photography in which a normal print can be obtained even from the exposure area during cropping photography, and the operator can clearly instruct whether the print is a normal print or a cropped print (for example, a panoramic print). The aim is to provide the following at a low price.

08 Means for Solving the Problems To be explained in conjunction with FIGS. 1 and 2 showing an embodiment, the present invention is a method of normal print photography in which printing of a normal print area 51 in a film exposure area 50 is instructed. ,
This is applied to a camera in which trimming photography, which instructs printing of a predetermined trimming area 52 in a film exposure area 50, can be selected.

By blocking part of the subject light that has passed through the photographic lens when selecting trimming photography, a predetermined area 53 that is within the film exposure area 50 and is not included in either the normal print area 51 or the predetermined trimming area 52 is set. The above-mentioned problem is solved by providing a light-shielding member 10 and 20 for forming information instructing printing of the trimming area 52.

When E1 action trimming photography is selected, the light shielding member 10.20 blocks a part of the subject light that has passed through the photographic lens.
Normal print area 51 within the film exposure area 50
Information instructing printing of the predetermined trimming area 52 is formed in an area 53 that is not included in any of the trimming areas 52. According to this, since the normal print area is always exposed to light no matter which photographing mode is selected, a normal print can be obtained even from a frame that has been cropped. Furthermore, since the area 53 in which information is formed is within the film exposure area 50, the print operator can clearly see at a glance whether the print is a normal print or a trimmed print.

In the above-mentioned sections and section E, which describe the present invention in detail, figures of embodiments are used to make the present invention easier to understand, but the present invention is not limited to the embodiments.

F. Example An embodiment of the present invention will be described with reference to FIGS. 1M to 3.

FIG. 1 is a perspective view showing the main parts of a camera according to the present invention. 10.20 is a light shielding plate (light shielding member) arranged in front of the aperture AP, and each light shielding plate 10.20 is provided protruding from a horizontal portion 11.21 and the lower part of one end of this horizontal portion 11.21. It consists of a light shielding part 12.22 and a projection part 13.23 projecting from the upper part of the other end of the horizontal part 11.21. Notches 12a and 22a are formed in each of the light shielding parts 12.degree. 22 at the same position, and the notches are arranged so as to face each other in front of the aperture AP.

Each horizontal portion 11.21 is provided with a pair of long holes 11a, 11b and 21a, 21b (21b is not shown), and the long holes 11b, 21b overlap each other. Long hole 1
1a and 21a have guide pins 3 fixed inside the camera body.
1.32 are inserted respectively, and the elongated holes 11b,
A guide pin 33 is inserted into 21b, so that each light shielding plate 10.degree. 20 is guided by the pins 31 to 33 and is movable in the horizontal direction. In the illustrated state, the left and right portions of the aperture AP are covered by the light shielding portions 12.22.

In addition, a pin 1 is attached to the protrusion 13.23 of each light shielding plate 10.20.
3a and 23a are provided to protrude horizontally, and each pin 1
A wedge-shaped cam 41 can be inserted between 3a and 23a. The tip of a rod 42a of a plunger 42 made of, for example, a magnetic solenoid is attached to this cam 41, and the cam moves up and down as the rod 42a expands and contracts. FIG. 1 shows the rod 42a in its most contracted state.

Here, the light shielding plates 10 and 20 are biased by biasing springs (not shown) in a direction in which the pins 13a and 23a abut against the cam 41, respectively.

The plunger 42 is driven by a driver 43, and a manual changeover switch SWI provided on the surface of the camera body is connected to the driver 43.

This changeover switch SWI is operated when switching between normal print photography and panoramic print photography (corresponding to trimming photography).

FIG. 2 shows the film FI. In the figure, 50 indicates the exposure area of one frame, and the area 51 in this exposure area 50 is the area printed in the normal service size (
(normal print area).

Further, an area 52 excluding the upper and lower parts in the exposure area 50 is a panoramic print area (trimming area), and an area 53
is an area in the exposure area 5o that is not included in either the normal print area 51 or the panoramic print area 52.

Next, the operation of the embodiment will be explained with reference also to FIG.

When the changeover switch SW1 is off, panoramic photography is selected, and at this time the solenoid 42 is not energized and its engagement rod 42a is in the retracted position, and the light shielding plate 1
0 and 20 are in the illustrated state. Therefore aperture A
Both ends of P are covered by light shielding parts 12.22.

When taking a picture at this time, the subject light that has passed through the photographic lens is guided to the film FI and the film FI is exposed, but part of the subject light is blocked by the light shielding part 12.22, as shown in Fig. 3. In the area 53 within the exposure area 30 (an area not included in either the normal print area 51 or the panoramic print area 52), the four corners indicated by diagonal lines are not exposed. Here, the four corner parts are each light shielding part 12.
．． These portions correspond to the upper and lower portions of the notches 12a and 22a of 22. The fact that this portion is not exposed corresponds to information instructing printing of the panoramic print area 52.

Since the above information is formed in the area 53 in the exposure area 50 in this way, it is easier to see than when similar information is formed in the margin area outside the exposure area 50 (for example, between perforations), and the panoramic print is You can clearly see what should be done at a glance. In particular, in this embodiment, the notch 12a of each light shielding member 12.22.

Since a panoramic print area 52 is defined by connecting the edge portions Edl and Ed1' and Ed2 and Ed2' formed by 22a, the information content is easy to understand and easy to print.

Furthermore, since the normal print area 51 is exposed to light without being blocked even during panoramic photography, it is also possible to obtain a normal print from this frame. Furthermore, since the information is formed using the light from the object during photographing, there is no need for special equipment such as an LED for recording information or a drive circuit for the same, and there is no need for a significant increase in cost.

Furthermore, when the changeover switch SW1 is turned on to select normal photography in the state shown in FIG.
1 goes down. Along with this, the pins 13a and 23a move in the horizontal direction in the drawing against the biasing force of a spring (not shown), so that the light shielding plate 10 is guided to the left and the light shielding plate 20 is guided to the right by the guide bins 31 to 33, respectively. and the light blocking portion 11.12 is retracted from the aperture AP. Therefore, even when photographing is performed in this state, information formation using the subject light as described above is not performed, and the entire exposure area 5o is exposed. In other words, normal photography is performed.

Note that during panoramic photography, some data may be imprinted on the portions (shaded portions in FIG. 3) that are shielded from light by the light shielding members 10 and 20. According to this, clear data can be imprinted without being affected by the background, and the image during printing will not be damaged. Also, unlike the conventional method of imprinting data between pieces,
Prints with data can be obtained through general print processing. In this case, it is necessary to give support to the laboratory not to trim the animal.

Further, FIGS. 4 and 5 show another embodiment, and it is assumed that the camera of this embodiment has a zoom lens as a photographing lens. In a zoom lens, the distance between the lens LE and the film surface is long at the telephoto end, so the exposure area is 50 at the telephoto end.
b (FIG. 5) is narrower than the exposure area 50a at the wide-angle end. Here, W and T in FIG. 4 are exposure areas 50a and 50b.
W is the width when shooting at the wide-angle end, T is the width of the
1 and 2 respectively show the case where the photograph was taken at the telephoto end.

By the way, if panoramic photography is performed by inserting the light shielding plates 10 and 20 (only 10 is shown) into the optical path when the photographic lens is at the telephoto end, the information formed as described above will be lost due to the narrow angle of view. There is a possibility that the damage may extend to the normal print area, making normal printing impossible. Therefore, in this embodiment, considering that panoramic photography is effective when shooting at a wide angle, panoramic photography is limited to the wide-angle end, and the light shielding plates 10 and 20 can be inserted into the optical path only at the wide-angle end.

When the light shielding plate 10.20 is inserted at the wide-angle end, the above information is formed outside the exposure area 50b during telephoto. That is, as shown in FIG. 5, since the normal print area 51 (this is the same for both wide-angle and telephoto) needs to be narrower than the exposure area at least at the telephoto end, the light shielding plate 10.20 If the above information is formed outside the exposure area 50b at the time of insertion, the exposure of the normal print area 51 will not be hindered. Therefore, as described above, normal prints can also be obtained from frames taken by panoramic photography.

Note that the position and size of the panoramic area are not limited to those in the embodiment, and may be, for example, above or below the exposure area.

In this case, the position and size of the cutout of the light shielding portion may be changed depending on the position and size of the cutout. Furthermore, the information to be formed is not limited to the above-mentioned information; for example, it is possible to clearly indicate the panoramic area by reversing the light-shielding part and the exposed part, and it is also possible to indicate the positions of the four corners of the panoramic area. Anything is fine as long as it can be done.

Furthermore, although the camera capable of panoramic photography has been described above, the present invention is not limited to panoramic photography, and may be a camera that performs trimming photography that instructs printing of a predetermined area (trimming area) within the normal print area 52, for example. Furthermore, the structure of the light-shielding plate and the configuration of the device for moving the light-shielding plate are not limited to those in the embodiments, and the light-shielding member may be mechanically moved immediately upon operation of the photographing switching operation member, for example.

G0 Effects of the Invention According to the present invention, by blocking part of the subject light that has passed through the photographing lens when selecting trimming shooting, the object light that is within the film exposure area but not included in either the normal print area or the trimming area is Since information (information that instructs printing of the cropped area) is formed in the area, normal prints can be obtained even from frames during cropping shooting, which is convenient, and allows the print operator to print either normal prints or panoramic prints. This makes it extremely easy to judge whether or not the desired print is obtained. In addition, there is no need to use a dedicated marking means such as an LED, and it can be provided at a low cost.
