[0007]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a main part configuration diagram of a screen size switching camera showing a first embodiment of the present invention. The present screen size switching camera has a built-in data imprinting device for switching the screen size, and enables imprinting of data at a predetermined position on the photographed screen of each size that has been switched. Note that the switching screen of the photographing screen includes a standard size (hereinafter, referred to as N size) screen in a normal photographing (hereinafter, referred to as N photographing) mode, a half-size screen during half-size photographing, or a panoramic photographing ( There is a panorama size (hereinafter, referred to as P size) screen in the P shooting mode, but in the case of this camera, switching from a standard size screen in N shooting to a panorama size screen in P shooting. Shall be performed.

The camera according to the present embodiment mainly includes a photographing lens 8.
N and P photographing light beams 19a and 19b from the camera body 44
An image capturing unit that forms an image on the film 9 positioned at the opening 44d (see FIG. 3) and captures an image; a screen size switching mechanism that includes a screen switching mask A11 and a mask B22 that is positioned opposite to the screen switching mask A11; And a data imprinting unit.

The data imprinting device section includes a display section having a lamp light source 2, a reflection mirror 3, a condenser lens 4, a liquid crystal display 5 and the like, and a liquid crystal display 5 and a film 9 surface. Is formed by a data imprinting optical system provided in the camera.

The display unit will be described in detail with reference to FIG. 2. The display unit includes an external data display liquid crystal 14, a clock / liquid crystal driver IC 12, a data switching operation switch 13, and the reflection switch on the electric circuit board 1. A unit in which the constituent members of the data imprinting liquid crystal display unit 5 attached via the mirror 3, the lamp light source 2, the condenser lens 4, and the conductive rubber connector 10 are united is used. In this manner, the components that are unitized together with the circuit board 1 are arranged along the upper outer wall surface inside the camera body 20 (see FIG. 7). In this display unit, the light of the lamp light source 2 is irradiated rearward along the substrate 1, reflected downward by the reflection mirror 3, passed through the condenser lens 4, and passed through the condenser lens 4 for data imprinting liquid crystal. The light passes through the display 5. Then, the light is emitted to the data imprinting optical system. The condenser lens 4 is connected to the filament of the lamp light source 2 by the objective lens 6.
Is set so as to form an image at the position.

The data imprinting optical system is supported by a mask A11 of a screen size switching mechanism which moves up and down when the screen is switched, and a lens mounting portion 11e of the mask A11.
The objective lens 6 is obliquely provided on the projection 11f and the total reflection mirror 7 is obliquely provided on the projection 11f. Then, the transmitted light from the display unit 5 is taken in from the opening 11c of the mask A11, transmitted through the objective lens 6, reflected by the total reflection mirror 7 toward the film 9, and forms the imprint data.
Since the liquid crystal display 5, the objective lens 6, and the film 9 are in a conjugate position with the total reflection mirror 7 interposed therebetween,
The data imprinted characters on the liquid crystal display 5 form a clear data image on the photosensitive surface of the film 9. However, the image formation state of the data at the time of the P shooting with respect to the N shooting is within the range of the predetermined depth of focus.

The operation of the data imprinting optical system for each photographing state will be described. First, in the case of N photographing, P
When the switching knob 15 of the ring 33 is operated, the mask A11 itself and the objective lens 6 obliquely provided on the mounting portion 11e of the mask A and the reflecting mirror 7 obliquely provided on the protruding portion 11f change the photographing light flux 19a for N photographing. The mask A11 retreats upward to a position where it does not exist, and at the same time, the mask B22 also retreats downward, and the screen is switched to the N size. In this state, after the light of the light source 2 passes through the mirror 3 and the condenser lens 4 and then passes through the liquid crystal display 5, the mask A1
1 through the aperture 11c of the imaging optical system 1
Is reflected by the reflection mirror 7, the data is imaged at a predetermined position on the film 9, and the data is imprinted (see FIG. 6A).

In the case of P photographing, similarly, the P ring 3
By operating the switching knob 15 of No. 3, the masks A11 and B22 are moved to positions (11 ', 11' in FIG. 1) where the respective end faces 11d and 22d (see FIG. 5) define a P-size screen.
22 ') to switch the screen. Even in this state, the objective lens 6, the reflection mirror 7, and the supporting portions thereof are positioned so that the imaging light flux 19b of the P imaging does not vignet. Then, as in the case of N shooting, the light of the light source 2 passes through the mirror 3 and the condenser lens 4, then passes through the liquid crystal display 5, passes through the objective lens 6, and passes through the reflecting mirror 7. Is reflected to form an image of data at a predetermined position on the film 9, and the data is imprinted (see FIG. 6B).

The liquid crystal display 5, objective lens 6,
Since the film 9 has a symmetrical positional relationship via the total reflection mirror 7, the data imprinted characters of the liquid crystal display 5 form a clear data image on the photosensitive surface of the film 9.

Next, the details of the configuration of the screen size switching mechanism that supports the imaging optical system and switches the screen size will be described with reference to FIGS.

The above-mentioned mechanism is provided on the front surface of the standard opening 44d of the camera body 44, and is provided with a movable mask A11 and a mask B22 for switching the photographing screen, and a fitting portion of the body 44 whose axial direction is regulated. It mainly comprises a P-ring 33 which is rotatably fitted to 49a and operates to open and close the masks 11 and 22. The guide pins 11b and 12b of the mask A11 and the mask B22 have the straight guide grooves 44c of the main body 44.
Can be moved up and down respectively. And
Knob 1 fixed to operation arm 33f of P ring 33
5 is operated from the outside, the P-ring 33 is rotated, and the driving pins 1 of the masks A, B11, 22 are slidably fitted into the notches 33a, 33b provided on the inner periphery of the P-ring 33.
The mask A11 and the mask B22 through 1a and 22a
Can be moved to the respective screen size switching positions. That is, the P ring 33 is rotated counterclockwise (hereinafter referred to as CC).
(Referred to as W), the end faces 11d,
As shown in FIG. 4, 22d moves to a position where it does not interfere with the standard opening 44d for the N size, and rotates the P ring 33 clockwise (hereinafter referred to as CW) for the P size. As shown in FIG. 5, the image is moved to a position giving the height of the P size screen.

The operating arm 33f of the P-ring 33 is inserted through an elongated hole 44j of the main body 44. Also,
The rotational position of the P-ring 3 is regulated by abutting against the stopper hole end surfaces 33d and 33e of the P-ring 33 into which the protrusion 44b of the main body is inserted, and the N-size position and the P-size position of the masks A1 and B2, respectively. (See FIGS. 4 and 5). And the main body 44 for holding each position
The projection 33c of the P-ring is fitted into the click groove 44g or 44h with a predetermined detent force and positioned. As described above, the objective lens 6 and the total reflection mirror 7, which are the imaging optical system, are fixed to the mask A11, and move up and down in accordance with the movement of the mask A11.

Next, the operation of the screen switching mechanism will be described. By rotating the P-ring in the CCW direction, the screen is set to the N photographing state in FIG. In this state, the mask A11
Since the mask and the mask B22 are separated from each other and located outside the range of the standard opening 44d of the main body 44, the N size (standard size) of the actual screen is determined by the opening 44d. In this state, the contact surface 33d of the P ring is in contact with the main body stopper 44b, and the click projection 33c is fitted in the click groove 44g. When the operating arm 33f of the P-ring is rotated in the CW direction from this position, the pins 11a and 22a of the masks A11 and B22 are driven by the cutout grooves 33a and 33b of the P-ring 33, and the masks A11 and B22 guide the body 44. Groove 44c
Move down or up along. Then, the contact surface 33e contacts the stopper 44b, and the click protrusion 33c of the P ring 33 fits into the click groove 44h as shown in FIG. Then, the masks A11 and B22
End surfaces 11d and 22d approach each other up to a predetermined distance,
An area of a screen size of P size (panorama size) is formed.

Next, the date imprint switching operation in the N photographing mode and the P photographing mode will be described. In the N photographing state, the mask A11, the mask B22, the objective lens 6
And the total reflection mirror 7 and the supporting portion 11f thereof are located at positions where the N-size photographing light beam 19a is not vignetted. For example, imprinted characters as shown in FIG. 6A are photographed on the N-size screen. . Subsequently, when the knob 15 of the P ring 33 is operated to switch to the P shooting state, the mask A11,
The mask B22 moves to the P size photographing position approaching each other. At this time, the objective lens 6 and the total reflection mirror 7
Also lowers the P imaging light flux 19b to a position without vignetting integrally with the mask A11. At this time, the distance from the liquid crystal display to the image forming position is slightly extended, but is set within a predetermined depth of focus. The characters printed on the screen are the above N
The size is smaller than when shooting. FIG. 6B shows an example of imprinting in this case.

The above-described first method, which incorporates desired data into the N photographing screen and the P photographing screen, is incorporated as described above.
According to the camera of the embodiment, since the external data display liquid crystal 14 and the data switching operation switch 13 (see FIG. 2) are disposed on the same side of the substrate 1 as the lamp light source 2, FIG.
The display window 14a of the external data display liquid crystal 14 and the operation button 13a of the data switching operation switch 13 can be disposed on the upper surface 20a of the camera body 20 as shown in FIG. Becomes Further, the display window 14a is not covered with the fingers held by the camera. Further, since the condenser lens 4 is used, the distance between the liquid crystal display 5 and the lamp light source 2 can be reduced, and as shown in FIG.
Since the dimension L in the front-rear direction along the optical axis can be reduced and the substrate 1 can be formed compactly, the thickness of the entire camera does not increase even if it is disposed above the camera body 20.

Further, since the imprinting optical system is also switched in conjunction with the switching operation to the P photographing mode, a switch for detecting panoramic photographing switching becomes unnecessary. Furthermore,
Since the characters to be printed on the P size screen are smaller than the characters to be printed on the N size screen, there is an effect that the size of the characters can be suppressed when printing the P size having a large enlargement ratio at the time of printing. Furthermore, the light source 2 and the liquid crystal display 5 may be one set as in the case of the conventional N-size display, which is advantageous in terms of cost.

Next, a screen size switching camera according to a second embodiment of the present invention will be described with reference to FIG. 8A shows the state of the imprinting optical system at the time of N photographing, and FIG. 8B shows the state of the imprinting optical system at the time of P photographing.

In the first embodiment, the imprinting image plane of the P photographing screen is within the depth of focus, but some blurring of the image cannot be avoided. Therefore, the projection apparatus of the present embodiment is different from that of the first embodiment in that the objective lens 6 serving as the imaging optical system is supported by a holding member 52 separate from the mask A, and is used for N photography and P photography. In both cases, the imprinted image is a perfectly focused image. In the camera of the present embodiment, the subject photographing unit and the screen size switching mechanism are the same as those of the first embodiment. However, the masks A,
B51 and B51 are masks A and B1 of the first embodiment.
1 and 22 correspond respectively. Further, the light source 2, the reflection mirror 3, not shown in FIG. 8, the condenser lens 4, the liquid crystal display 5, the conductive rubber connector 10, the mask P-ring 33 and the like shown in FIG. Apply the ones.

The imprinting apparatus of the present embodiment comprises a supporting portion 5 of a mask A51 which moves up and down by switching between N and P photographing.
At 1f, a total reflection mirror 7 that reflects the data imprinting light beam in the direction of the film 9 is fixed. The objective lens 6 is supported by a holding frame 52 separate from the mask A51.
The holding frame 52 is slidable in the moving direction of the mask A,
A tension spring 53 is suspended from the mask A51.
Then, at the time of N photographing, the mask A51 and the holding frame 52 are kept in a state in which a predetermined relative distance is maintained (see FIG. 8A). When the mask A51 is moved downward by switching to the P photographing state and a P screen is formed by the end face 51d, the holding frame 52 is prevented from moving integrally with the mask A51 by the stopper 44k of the camera body. The state shown in FIG. 8B is obtained. In this state, it is possible to form an image in which the data to be imprinted on the P-size screen is smaller than the character at the time of N shooting and which is in a focused state.

Next, an imprinting apparatus according to a third embodiment of the present invention will be described with reference to FIG. 9A shows the state of the imprinting optical system at the time of N photographing, and FIG. 9B shows the state of the imprinting optical system at the time of P photographing.

As in the second embodiment, the imprinting apparatus of this embodiment is an apparatus in which the imaging state of imprinted data is improved, and includes an objective lens 6 and an all-reflection mirror as an imaging optical system. 7 has a structure that supports the liquid crystal display body 5 integrally with the mask A61 that holds the mask 7, so that the images captured in both N shooting and P shooting are perfectly focused images. In addition,
In the camera of the present embodiment, the subject photographing unit and the screen size switching mechanism are the same as those of the first embodiment. Furthermore,
The light source 2, the reflection mirror 3 and the taking lens 8, not shown in FIG. 9, the condenser lens 4, the liquid crystal display 5, the conductive rubber connector 10, the P-ring 33 and the like are also the same as those in the first embodiment. Apply

In the projection apparatus of this embodiment, the objective lens 6 is fixed to the support 61e of the mask A61 which moves up and down by switching between N and P photography, and the total reflection mirror 7 is fixed to the support 61f. Is done. Further, the liquid crystal display 5 is supported by a supporting portion 61g integral with the mask A61 on the condenser lens 4 side above the mask A61. Therefore, even if the mask A61 changes its position, the positional relationship among the liquid crystal display 5, the objective lens 6, the reflection mirror 7 and the film 9 is not changed, and the in-focus image is always displayed on the film 9 surface. It is possible to form an image.

The screen size switching camera of each embodiment described above can be applied to a single focus camera and a zoom camera as long as it is a camera capable of displaying P data and displaying data. In the present embodiment, a mechanism in which the imprinting optical system is linked to the mask A is adopted. However, in the present invention, in addition, the objective lens 6 of the imprinting optical system is linked to the P imaging switching operation knob 15. A mechanism for moving the reflection mirror 7 may be used.
