Abstract

PURPOSE:To obtain a film integrated type camera which is not bulky when it is not used by fitting a direct optical view finder to the camera main body or the packing case thereof so that it can be popped up. CONSTITUTION:The direct optical view finder 8 consisting of a frame body 9 which can secure a required visual field is fitted to the camera main body 1 or the packing case 2 thereof so that it can be popped up. That means, the finder 8 is respectively provided with an objective window 10, which can secure the required visual field, to the front plate 9a of the frame body 9 having a U-shaped side surface and an eye-piece window 11 to the back plate 9b thereof. Besides, it is fitted in flat groove parts 12a and 12b provided to the front surface and the back surface of the upper part of the camera main body 1 so that it can be popped up. Then, the finder 8 is popped up to a use position with one operation by making the bulb of the thumb 17a of a hand 17 supporting the camera main body 1 abut on a finger abutting part 16 and pushing it up. Thus, the film integrated type camera which is not bulky when it is not used and which is provided with the direct optical view finder is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a disposable film-integrated camera in which various functions necessary for photographing are integrally incorporated into a main body preloaded with film.

1. Prior Art] -S. This type of film-integrated camera is constructed so that when all the frames of the preloaded film have been photographed and developed, the camera itself is broken and the film inside is taken out. The camera body is designed to be disposable after each roll of film is used. For this reason, it is necessary to make this film-integrated camera as simple and inexpensive as possible while maintaining the photographic function. In particular, the finder has a see-through window that penetrates the camera body from the back to the front and does not fit a lens.

[Problem that the invention is trying to solve]

However, in order to secure the necessary field of view with a see-through finder like the one mentioned above, the window on the front side (objective side) of the camera body must be large (especially when using a wide-angle lens that enables panoramic shooting). growing).

Therefore, the finder occupies a large space within the camera body, which is a major reason why the camera body cannot be made smaller.

SUMMARY OF THE INVENTION In view of the above points, an object of the present invention is to provide a film-type camera equipped with a see-through type viewfinder which allows the camera body to be made smaller.

[Means to solve the problem]

In order to achieve the above object, the present invention has a see-through type finder consisting of a frame that can secure the necessary field of view, which is attached to the camera body or its exterior case so that it can be pumped up, and the space inside the camera body is occupied by the finder. Either the camera body is made smaller to avoid this problem, or the camera body is designed to maintain its current size while speeding up the construction of a mechanism that expands the functions of a strobe unit, etc.

〔Example〕

The present invention will be described below based on an embodiment shown in the accompanying drawings.

Figure 1 is a perspective view of the viewfinder in use, Figure 2 is a side view of the same, Figure 3 is a perspective view of the viewfinder when it is stored, Figure 4 is a front view of part of the finder, and Figure 5 is the pump-up operation. It is a perspective view of the back side of the time.

In the figure, reference numeral 1 denotes a camera body, and an unexposed film (not shown) is stored in advance in the camera body l.

Reference numeral 2 denotes an outer case enclosing the camera body l, and the outer case 2 is made of cardboard or the like and has a box shape. The exterior case 2 is provided with an opening 3 through which a photographing lens section 4, a winding knob 5, a counter 6, a release button 7, and a finder 8 are exposed.

The finder 8 includes an objective window IO1 and a rear plate 9b that can secure the necessary field of view on the front plate 9a of the frame 9 whose side surface is shaped like a ■.
An eyepiece window 11 is provided at each. The finder 8
The front and rear plates 9a and 9b of the frame 9 that constitute the camera body 1 have flat grooves 12a and 12 provided on the front and rear surfaces of the upper part of the camera body 1, respectively.
b so that it can be pumped up. That is, the finder 8 is used with the front and rear plates 9a and 9b of the frame 9 projecting upward from the top surface of the camera body 1 as shown in the first diagram, and with the eyepiece window 11 and the objective window 10 electrically connected as shown in the second diagram. be done. Further, when not in use, the upper plate 9c of the frame 9 is brought into close contact with the upper surface of the camera body l, as shown in the third figure, so that the camera can be stored in a small size. In this stored state, the eyepiece window 11 and the objective window 10 are blocked by the camera body 1 and are non-conductive.

Reference numeral 13.13' denotes locking projections provided outward on the lower ends of both the front and rear plates 9a and 9b of the frame 9, and the locking projections 13.1
The receivers 3' provided at the upper ends of the opposite edges of the flat grooves 12a and 12b together with the projections 14 and 14' constitute means for preventing the frame 9 from being pulled out.

15a 15a', 15b, and 15b' are small protrusions provided at the upper and lower portions of the opposing edges of the flat grooves 12a and 12b, with which the locking protrusions 13 and 13' of the frame body 9 engage. That is, this is for maintaining the finder 8 in the pumped-up state to the use position and in the stored state.

Reference numeral 16 denotes a finger rest provided on the outer surface of the rear plate 9b of the frame 9 for pumping up the finder 8 to the use position. That is, as shown in FIG.
By pushing up the finder 8 as shown in the arrow a', it is possible to pop-amplify the finder 8 to the use position with one touch. Conversely, the finder 8 can be stored by pressing the top surface 9C of the frame 9 downward.

In addition, in the above embodiment, the frame 9 constituting the finder 8
is attached directly to the camera body l, but it may also be attached to the exterior case. Further, although the frame body 9 is shaped like a side square, the shape can be freely determined without departing from the spirit of the present invention.

Although the camera body 1 is not equipped with a strobe in the above embodiment, it may be equipped with a strobe.

In the drawing, the surface of the outer case 2 has no pattern, but in reality, appropriate explanatory notes, designs, etc. are printed on it.

〔Effect of the invention〕

As described above, the present invention is characterized in that a see-through type finder consisting of a frame that can maintain the required field of view is attached to the camera body or its exterior case in a pop-up manner. It protrudes outside the camera body, so it does not take up much space when not in use, that is, when carried. In addition, the space inside the camera body is not occupied by the viewfinder, making it possible to downsize the camera body, and it also makes it possible to incorporate a strobe unit while maintaining the current size, which has various excellent effects. It is something that plays.
