Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information imprinting device for imprinting information such as a date on a photograph, and more particularly to the structure of a light collecting member constituting an optical system between a light source section and a film.

[0002]

2. Description of the Related Art Cameras having a date imprinting function have been widely used in order to check photographed dates and confirm photographed dates and to easily organize photographs. In order to operate the date imprinting function, the camera has a built-in information imprinting device.

By the way, in recent years, in order to increase the variety of expression methods by photographs and increase the enjoyment of photographing, panoramic photographs in which the long sides of ordinary photographs are extended have become popular. A so-called pseudo-panorama structure is often used for a camera for taking a panoramic photograph, in which the upper and lower portions of a normal size frame are shielded from light to photograph a panoramic size frame. That is, if it is a 35 mm film, the normal size is 36 mm × 24 mm, and the panorama size is, for example, 36 mm.
You can easily take panoramic photos if you shoot as mm x 16 mm.

Here, since the positions of the long sides of the panoramic size frame and the normal size frame are different, it is difficult to use the same information imprinting device. That is, as shown in FIG. 4, since the information imprinting position Ld in the normal size frame L and the information imprinting position Pd in the panorama size frame P are different, the imprinting positions Ld and Pd of each screen size are different. In many cases, a structure provided with a corresponding information imprinting device is used.

However, in the above information imprinting apparatus, since two sets of similar optical systems must be provided from the light source section to the film surface, there are many duplications of parts and it is difficult to reduce the size and weight of the camera. . Therefore, there is known an information imprinting device in which the number of parts is reduced by making the light source unit common.

As shown in FIG. 4, the information imprinting device 1 includes a light collecting member 4 facing the film 3 on the side of the aperture 2 and a pair of Ls provided above the light collecting member 4.
It is composed of the ED group 5. The light collecting member 4 is
The film 3 is composed of a normal size imprinting section 6 facing the upper end of the normal size frame L and a panoramic size imprinting section 7 facing the upper end of the panoramic size frame P.

The normal size imprinting section 6 has an entrance lens section 6a directed upward and an exit section 6b directed toward the film 3, and an appropriate prism 6c is provided between them. Also, the panorama size imprinting section 7
Has an entrance lens section 7a directed upward and an exit section 7b directed toward the film 3, and an appropriate prism 7c is provided between them.

The LED group 5 is provided above the space between the incident lens portions 6a and 7a via appropriate diaphragms 6d and 7d. The LED group 5 includes seven dot-shaped LEDs 5a in a row. It is arranged side by side.

When the film 3 is fed after the exposure by photographing is completed, the information imprinting device 1 on the downstream side of the aperture 2 is operated. That is, for example, in the case of being photographed in the normal size, when the information imprinting position Ld of the frame L is fed to a position facing the emitting section 6b of the normal size imprinting section 6, an appropriate one of the LEDs 5a is fed. The object is turned on and off, and after the film 3 is slightly fed, the appropriate LED 5a is turned on and off again. Therefore, characters such as dates can be printed on the film 3 by repeating the blinking of the LED 5a and the feeding of the film 3. Although the light rays from the LED group 5 are also emitted from the emission portion 7b of the panoramic size imprinting portion 7, the emitted light is blocked by a shutter plate (not shown), and the film 3
It is prevented from being burned into.

On the other hand, when the image is taken in the panorama size P, the shutter plate shields only the emission part 6b of the normal size imprinting part 6, and the exit part 7b of the panoramic size imprinting part 7 emits light. By the emitted light, the film 3 is printed on the information imprinting position Pd in the same procedure as described above.

[0011]

However, in the structure of the information imprinting apparatus 1 described above, since the LED group 5 is shared, the following problems occur.

As shown in FIGS. 4 and 5, since the LED group 5 is located above between the incident lens portions 6a and 7a,
The light rays emitted by the lighting of the LED group 5 pass through the diaphragms 6d and 7d and are obliquely incident on the optical axes of the incident lens portions 6a and 7a. For this reason, this ray is incident on the incident lens portion 6a,
The light is transmitted through the optical axis of 7a, is reflected by each prism 6c, 7c, and is emitted from the emitting portions 6b, 7b. The position at which the emitted light is emitted is with respect to the central axis of each of the emitting portions 6b, 7b. It will be biased to the opposite side of the LED.

However, due to the above-mentioned deviation, the optical path of the emitted light comes close to the side end surface of the condensing member 4, and the flare is likely to occur due to the influence of the reflection of the side end surface. When flare occurs, the contrast of the emitted light is reduced, and unevenness may occur in the printed characters and the like.

In order to prevent this flare, it is necessary to appropriately separate the optical path from the side end surface of the light collecting member 4, and for this reason, the light collecting member 4 is indicated by a chain double-dashed line in FIG. Increase the thickness of the biased side part of the auxiliary side part 6d,
A structure with 7d is conceivable. As a result, the optical path is separated from the side end surface, so that the influence of flare is reduced.

However, with this structure, the light-collecting member 4 itself becomes large, which hinders the reduction in size and weight of the camera.

Therefore, it is an object of the present invention to provide an information imprinting device which can prevent flare from occurring without increasing the size of the camera.

[0017]

In order to achieve the above-mentioned object, an information imprinting device for a camera according to the present invention comprises an entrance portion and an exit portion which are curved surfaces, at least one of which has an imaging function. A light-collecting member that forms a light-collecting system that forms an image of incident light that has entered from the incident unit on a film surface that is disposed so as to face the emitting unit, and a light source unit that causes light rays to enter the incident unit. In the information imprinting device of the camera, the shape center axis of the incident part and the optical axis center of the incident light are appropriately separated, and the shape center axis of the emission part and the optical axis center of the emitted light are appropriately separated. The optical axis center of the incident light and the optical axis center of the emitted light are arranged so as to be located on opposite sides of the shape central axis of the incident portion and the emission portion.

Here, the shape center axis is a geometrical center when the entrance portion and the exit portion are viewed from the front, and an axis located at substantially the same distance from any side end surface of the light collecting member. I mean. Therefore, the center of the optical axis passing through the center of curvature of the lens curved surface of the entrance portion or the exit portion does not coincide with the shape center axis.

Further, the structure is such that an appropriate distance is provided between the optical path of the incident light and the side end surface of the condensing member, and even if a light ray deviating from the optical path is reflected by the side end surface, it is returned to the original optical path. The feature is that it hardly penetrates.

Further, a structure is provided in which an appropriate distance is provided between the optical path of the emitted light and the side end surface of the condensing member, and even if a light beam deviating from the optical path is reflected by the side end surface, the original optical path is restored. The feature is that it hardly penetrates.

In addition, a plurality of the light-collecting members sharing the same light source unit are arranged in parallel, and the respective emitting units face different positions on the film surface.

On the other hand, the light source unit is composed of a plurality of point-shaped light emitting bodies arranged in an appropriate arrangement, and an appropriate one of the light emitting bodies is turned on and off, and the film is fed to sequentially move the printing position. Thus, information such as characters is printed on the film.

Further, the light source section is composed of 7-segment luminous bodies arranged in a substantially "8" shape, and an appropriate one of the luminous body segments is turned on / off and the film is fed. It is characterized in that information such as arithmetic figures is printed on the film by sequentially moving the printing position.

[0024]

When the exposure is performed by photographing, the light source section emits light at the same time as or after the exposure. Here, the light source unit is composed of, for example, 7-segment LEDs arranged in a substantially "8" shape, 7-dot LEDs arranged in a line, or the like.

Then, the light beam from the light source unit is incident on the incident portion of the light collecting member, and this light beam is collected by the light collecting system,
It is emitted from the emitting portion. This emitted light reaches the film surface, and information such as characters is printed on it.

When the light source section is composed of 7-dot LEDs arranged in a line, the appropriate LEDs are turned on and off, the film is slightly fed, and then the appropriate LEDs are turned on and off again. Then, by repeating this blinking and feeding, characters and the like are formed and printed.

By the way, the shape central axis of the incident portion and the optical axis center of the incident light are appropriately separated, and the shape central axis of the emitting portion and the optical axis center of the emitted light are appropriately separated so that the incident light is Since the optical path of and the optical path of the emitted light are arranged so as to be located on the opposite sides of the shape central axis of the incident part and the outgoing part, these optical paths should be largely deviated from the central axis of the shape. In addition, the condensing member is not upsized.

Further, since the distance between the optical paths of the incident light and the outgoing light and the side end surface of the condensing member is appropriately maintained, even if a light ray deviating from the optical path or the like is reflected by the side end surface, It hardly penetrates into the optical path of, and flare is prevented as much as possible.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The information imprinting device for a camera according to the present invention will be specifically described below with reference to the illustrated embodiments.
In the present embodiment, the case where the information imprinting device is provided in a camera that can be switched between a normal size and a panoramic size in which upper and lower parts of the normal size are shielded from light is described.

As shown in FIG. 2, an aperture 12 is provided at the rear of the taking lens 10 of the camera body, and the aperture frame of the aperture 12 has a size substantially equal to a frame of a normal size. An upper light-shielding plate 14 is provided on the upper part of the aperture frame, and a lower light-shielding plate 16 is provided on the lower part, and these light-shielding plates 14 and 16 are centered on rotary shafts 14a and 16a along the upper and lower ends of the aperture 12. It is supposed to be rotatable. That is, when the light shielding plates 14 and 16 are opened, the normal size image is taken, and when the light shielding plates 14 and 16 are closed, the upper and lower parts of the normal size are shielded from light and the panoramic size image is taken. A return spring 18 made of an appropriate coil spring is attached to each of the light shielding plates 14 and 16 so that they are normally opened.

Further, crank portions 14b and 16b are formed at one ends of the rotating shafts 14a and 16a, and the crank portion 14b of the upper light shielding plate 14 is engaged with the switching projection portion 20a of the switching plate 20.

It has a reference numeral 24a and an input lever 24c, and is swingable around a rotary shaft 26 extending in the front-rear direction of the camera. By the swing of the switching lever 24, the switching plate 20 is slid vertically.

Then, the input lever 24 of the switching lever 24
c is linked to a changeover switch (not shown) outside the camera, and is swung by switching between the normal size and the panorama size of the changeover switch. That is, "P" in FIG.
When it is swung in the direction, the engaging protrusion 2 of the output lever 24a
Since 4b slides the switching plate 20 downward, the light shielding plates 14 and 16 are closed to form a panoramic size, and when the switching plate 20 is swung in the "L" direction, the engaging projection 24b moves the switching plate 20 upward. Since it slides, the light-shielding plates 14 and 16 are opened to the normal size. A finder switching device (not shown) and the like are linked to the changeover switch.

On the other hand, a light condensing member 28 is disposed on the side of the aperture 12, and as shown in FIGS.
The condensing member 28 is integrally provided with a normal size imprinting section 30 and a panoramic size imprinting section 32. In the normal size imprinting section 30, the entrance lens section 30a as an entrance section is directed upward, and the exit section 30b is formed into the film 34.
And an appropriate prism 30c is provided between the entrance lens section 30a and the exit section 30b. Further, in the panorama size imprinting section 32, an entrance lens section 32a as an entrance section is directed upward, and an exit section 32b.
Is directed to the film 34, and an appropriate prism 32c is provided between the incident lens portion 32a and the emitting portion 32b.

A diaphragm plate 30d is arranged above the entrance lens portion 30a of the normal size imprinting portion 30.
The diaphragm through hole of the diaphragm plate 30d is located on a straight line connecting an optical axis S _{1 of the} incident lens portion 30a described later and the LED group 36. Further, a diaphragm plate 32d is arranged above the entrance lens part 32a of the panorama size imprinting part 32, and the diaphragm through hole of the diaphragm plate 32d has an optical axis S _{2 of the} entrance lens part 32a described later. And the LED group 36 are located on a straight line.

The emission section 30b of the normal size imprinting section 30 is arranged at a position facing the upper end of the normal size frame L of the film 34, and the emission section of the panoramic size imprinting section 32 is provided. 32b is disposed at a position facing the upper end of the panoramic size frame P of the film 34.

Further, an LED group 36 is provided as a light source section above the space between the incident lens sections 30a and 32a.
The D group 36 is composed of seven dot-shaped LEDs 36a arranged in a line. The LEDs 36a can be turned on and off freely in correspondence with the feeding of the film 34, and characters and the like are printed by blinking and feeding the film 34.

By the way, as shown in FIG. 1, in the normal size imprinting section 30 of the condensing member 28, the incident lens section 30a is provided.
The optical axis S ₁ passing through the center of curvature of the lens surface of the LED from the central axis C ₁ on the shape of the normal size imprinting portion 30
It is slightly biased toward the group 36 side. That is, the above LED
The light rays from the group 36 pass through the diaphragm plate 30d, and do not pass through the central axis C ₁ of the shape of the incident lens portion 30a, but pass through the optical axis S ₁ .

The geometrical central axis C ₁ is the geometrical center when the incident lens portion 30a is viewed from the front, and is substantially the same from any side end surface of the condensing member 28. It means the axis at the distance.

On the other hand, in the panorama size imprinting section 32, similarly, the optical axis S ₂ passing through the center of curvature of the lens surface of the incident lens section 32a is from the central axis C ₂ of the shape of the panorama size imprinting section 32. It is slightly offset to the LED group 36 side. That is, the light rays from the LED group 36 pass through the diaphragm plate 32d and do not pass through the central axis C ₂ of the incident lens portion 32a but pass through the optical axis S ₂ .

Further, as shown in FIG.
A shutter plate 38 is provided slidably in the vertical direction between the film 34 and the film 34, and an engaging protrusion 38a is formed at a lower end portion of the shutter plate 38. The engagement protrusion 38a is engaged with a part of the switching plate 20, and the shutter plate 38 also slides as the switching plate 20 slides. Also, the shutter plate 38
Includes a position facing the emitting portion 32b of the panorama size imprinting section 32 when the switching plate 20 is in the panoramic size shooting position and a normal size imprinting section 30 when the switching plate 20 is in the normal size shooting position. A through hole 38b is formed at a position facing the emitting portion 30b, and light emitted from the emitting portions 30b and 32b can pass therethrough.

The light condensing member 28, the LED group 36, the shutter plate 38 and the like constitute an information imprinting device 40.

The operation of the information imprinting apparatus according to this embodiment constructed as described above will be described below.

The photographer operates the changeover switch before photographing to set the screen size. Here, when the panorama size is set, as shown in FIG. 2, the switching lever 24 is swung in the “P” direction and the switching plate 20 is slid downward. By this sliding, the crank portion 14b of the upper light shielding plate 14 engaged with the switching protrusion 20a of the switching plate 20 and the reversing lever 22 are swung, and the respective light shielding plates 14 and 16 resist the return spring 18. Closed. As a result, the upper and lower portions of the normal size frame L are shielded from light, and the panorama size frame P is photographed.
Then, the release is waited in this state.

When the release button is pushed down, exposure is performed. After exposure, the film 34 is fed, and at this time, the LED group 36 is turned on.

That is, when the film 34 is fed to the position where the information imprinting position Pd of the photographic frame P is opposed to the emitting part 32b of the panorama size imprinting part 32, seven LEDs are fed.
Appropriate ones of 36a are turned on and then turned off immediately. Then, after the film 34 is slightly fed,
The appropriate LED 36a is turned on again and turned off. Therefore, by repeating the blinking of the LED 36a and the feeding of the film 34, a character or the like is printed at the imprinting position Pd. Then, when the feeding of the film 34 is completed, the release of the next frame is waited.

By the way, the light rays from the LED group 36 are
After passing through the aperture holes of the diaphragm plates 30d and 32d, the light is incident on the incident lens portion 30a of the normal size imprinting portion 30 and the incident lens portion 32a of the panorama size imprinting portion 32, and any of the imprinting portions 30, 32 However, the light is reflected by the appropriate prisms 30c and 32c and emitted from the emitting portions 30b and 32b.

Here, as shown in FIG. 2, the shutter plate 38 is positioned below during panorama size photography,
A through hole 38b below the shutter plate 38 is superposed on the emission part 32b of the panoramic size imprinting part 32, and the position facing the emission part 30b of the normal size imprinting part 30 is shielded from light.
Therefore, although the light rays from the LED group 36 are emitted from the emitting portions 30b and 32b of the imprinting portions 30 and 32 of each size,
Only the light rays from the emitting portion 32b of the panorama size imprinting portion 32 are printed on the film 34.

By the way, as shown in FIGS. 1 and 3, in the normal size imprinting section 30, the optical axis S ₁ of the incident lens section 30a is located on the LED group 36 side with respect to the central axis C ₁ of the shape. It is deviated, and the incident light is obliquely incident on the optical axis S ₁ . Then, the incident light, when transmitted obliquely with respect to the center axis C ₁ of the shape when passing through the interior of the condensing member 28 is emitted from the emitting unit 30b is a central axis C ₁ of the above shape It is biased and emitted to the side opposite to the optical axis S ₁ of the incident lens portion 30a.

On the other hand, in the panorama size imprinting section 32, the optical axis S ₂ of the incident lens section 32a is deviated to the LED group 36 side with respect to the geometrical central axis C ₂ , and the The light ray is obliquely incident on the optical axis S ₂ . And
The incident light is transmitted obliquely with respect to the central axis C ₂ of the shape when passing through the inside of the condensing member 28, and is sandwiched with the central axis C ₂ of the shape when being emitted from the emitting portion 32b. It is biased and emitted to the side opposite to the optical axis S ₂ of the incident lens portion 32a.

Therefore, in each of the imprinting portions 30 and 32 of each size, an optical path of incident light and an optical path of outgoing light exist on the opposite side with respect to the central axes C ₁ and C ₂ of the shape. Therefore, as compared with the case where the optical path of the incident light and the optical path of the emitted light exist on one side of the shape central axes C ₁ and C ₂ as in the conventional case, the distance between the side end surface of the condensing member 28 is sufficiently large. Since it can be taken, a light ray traveling to a position other than the optical path is hardly reflected by the side end face and enters the original optical path, and there is no possibility of flare. Further, the thickness of the light collecting member 28 can be minimized, which can contribute to the reduction in size and weight of the camera. Further, since it is not necessary to add another structure for flare prevention, it is possible to save the manufacturing cost.

On the other hand, when the screen size is set to the normal size, the switching lever 24 is swung in the "L" direction and the switching plate 20 is slid upward as shown in FIG. By this sliding, each of the light shielding plates 14 and 16 becomes free and is opened by the return spring 18. Therefore, the aperture 12 is fully opened, and the frame L of the normal size is photographed. Then, the release is waited in this state.

When the release button is pressed down, the exposure is performed, and when the film 34 is fed to the position where the information imprinting position Ld of the photographing frame L is opposed to the emitting section 30b of the normal size imprinting section 30, the LED group is fed. 36 turns on and off.
The fact that characters and the like are printed by the blinking of the LED 36a and the feeding of the film 34 is the same as in the case of photographing in the panoramic size described above.

Further, the shutter plate 38 is located above, and the through hole 38b above the shutter plate 38 is superposed on the emitting part 30b of the normal size imprinting part 30 so that the panorama size imprinting part 32 is formed. The position facing the emitting portion 32b is shielded from light. Therefore, although the light rays from the LED group 36 are emitted from the emitting portions 30b and 32b of the imprinting portions of each size, only the light rays from the emitting portion 30b of the normal size imprinting portion 30 are printed on the film 34.

Therefore, according to the present embodiment, since the light ray passing through the inside of the light converging member 28 maintains an appropriate distance from the side end face, flare is generated by the light reflected on the side end face. Is prevented as much as possible. Therefore, the characters printed on the film 34 are not uneven, and the characters printed are easy to see.

Further, the central axis C of the shape of the light collecting member 28 is
_Since the optical path of the incident light and the optical path of the emitted light are provided on the opposite sides of ₁ and C ₂ , the thickness of the condensing member 28 can be minimized. Therefore, it is possible to contribute to reduction in size and weight of the camera.

Further, since the normal size imprinting section 30 and the panoramic size imprinting section 32 are integrally formed, they can be easily assembled at the time of assembling the camera, and the time and effort for production are reduced.

Further, since one set of LED groups 36 is commonly used for the normal size imprinting section 30 and the panorama size imprinting section 32, it is not necessary to use a plurality of LED groups,
The number of parts can be saved and the camera can be prevented from increasing in size.

Since the shutter plate 38 is slid up and down, only the light rays from one of the emitting portions 30b and 32b are printed on the film 34. It is possible to prevent characters from being imprinted at the embedding position Pd.

In addition, since the light rays from the LED group 36 are condensed by the incident lens portions 30a and 32a and then projected onto the film 34, clear printing is performed and bleeding of characters can be prevented.

Further, since the LED group 36 is formed by arranging seven dot-shaped LEDs 36a in a line, characters and the like can be formed relatively freely. Therefore, the information printed on the film 34 is not limited to numbers such as dates, but alphabets, katakana, and the like can be printed, and the types of information display are increased.

[0061]

As described above, according to the information imprinting apparatus for a camera of the present invention, the center axis of the shape of the incident portion of the light collecting member and the center of the optical axis of the incident light are appropriately separated and emitted. The optical axis center of the incident light and the optical axis center of the emitted light are opposite to each other with the central axis of the shape of the incident portion and the optical axis of the emitted portion sandwiched therebetween. Since the optical path is disposed on the side, the optical path does not deviate largely from the shape central axis, and the thickness of the light collecting member can be minimized. Therefore, the size and weight of the camera can be reduced.

Further, a structure is provided in which an appropriate distance is provided between the optical path of the entrance portion or the exit portion and the side end surface of the condensing member, and even if a light ray deviating from the optical path is reflected by the side end surface, Since almost no light penetrates into the optical path of, the flare is rarely generated, and the characters etc. imprinted in the photograph become clear and even. Further, since it is not necessary to add another structure for flare prevention, it is possible to save the manufacturing cost.

Further, since a plurality of light-collecting members sharing the same light source unit are arranged in parallel and the respective emitting units are opposed to different positions on the film surface, it is possible to use a camera in which the screen size of the shooting frame can be switched. Even if there is, information can be imprinted on the frames of each screen size. At this time, since the light rays are emitted from the respective emission portions, it is desirable to provide a light shielding plate for shielding the light rays from the emission portions other than the emission portion corresponding to the screen size taken. Further, since it is not necessary to provide a plurality of light source units, the number of parts can be saved and the camera can be prevented from becoming large.

Further, the light source section is constituted by an appropriate array of a plurality of point-shaped light emitting bodies, and an appropriate one of the light emitting bodies is turned on and off, and the film is fed to sequentially move the printing position. Thus, since the information such as characters is printed on the film, the characters and the like are not limited to numbers, and alphabets, katakana, simple pictographs, etc. can be imprinted. Therefore, the types of imprinted information are expanded and the range of application is expanded.

On the other hand, the light source section is composed of a 7-segment luminous body arranged in a substantially "8" shape, and an appropriate one of the luminous body segments is turned on and off and the film is fed. In the case of a structure in which information such as mathematical figures is printed on the film by sequentially moving the printing position by, for example, LE of 7 segments
The light source unit can be obtained at a low cost by using D.
