Abstract

PURPOSE:To attain stable attitude at pickup by deviating the upper/lower faces of a flat rectangular prism whose width and length are larger than the height in the camera main body in the backward/forward direction of the lengthwise direction so as to make the size small and to obtain excellent portable performance. CONSTITUTION:The upper/lower faces of a flat rectangular prism whose width and length are larger than the height in the camera main body are deviated in the backward/forward direction of the lengthwise direction and a face made orthogonal to the front face and the rear face respectively is formed to a part where the front face and the lower face and the rear face and the upper face are crossed at a sharp angle. Moreover, one side face is formed to be a part 1 gripping the upper/lower faces by a finger and a photographing lens 3 is provided to the front face and a finder 2 is projected from the face orthogonal to the rear face. Furthermore, it is preferred to provide a surface member made of rubber of leather being an antislipping member offering ease of gripping to the grip 1. Thus, the camera is formed to be small in size, excellent handy performance and stable pickup attitude are offered and a short finder optical path is given and the circuit board of simple shape with a large area and a video floppy are arranged without irrationality.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a still video camera.

[Background of the invention]

Still video cameras magnetically record image information, shooting conditions, audio, etc. on a video floppy, so they are heavier and bulkier than film cameras, and their image processing and control circuits are more complex. Therefore, the circuit board area must be increased or the packaging density must be increased.0 It is easier to increase the packaging density of a circuit board as the board has a larger area and a simpler shape.

When a still video camera is constructed in the shape of a film camera shown in FIG.
Since the video floppy and circuit board are arranged parallel to the front and rear surfaces of the camera, it is necessary to arrange them in a position away from the rear viewfinder 2, or to place the circuit board in the viewfinder 2 or even between the photographic lens 2 and the camera. It is necessary to use a shape that has a cut-out part that can be penetrated, which reduces the packaging density, and this causes the problem that the camera becomes even larger.

In addition, when a still video camera is constructed in the shape shown in Figure 4-1, the gripping part 1 protruding from the bottom surface allows for secure gripping, and the video floppy and circuit board can be placed parallel to the top and side surfaces. 5, which can solve some of the problems caused by the configuration shown in Figure 3.
However, there is a problem in that it is difficult to increase the area of the circuit board without increasing the height or width of the camera body that includes the photographic lens 3 and finder 2, and also because of the protruding grip part 1. It is bulky and inconvenient to carry, and the optical path of the finder 2 is long, making it uneconomical in terms of volume.

In addition, as shown in Fig. 5, a still video camera is
If it is made into a flat box shape that can be grasped by placing your fingers on the top and bottom surfaces of one side, video floppies and circuit boards can be placed parallel to the top and bottom surfaces, allowing for a large board surface. However, there is still the problem that the optical path of the finder 2 is long, which is uneconomical in terms of volume, and when the photographer holds the camera, his or her elbows are pushed forward, making it difficult to hold the camera. The problem is that it is unstable and easily fatigued.

Note that 4 is the floppy drive unit door.

[Purpose of the invention]

The present invention has been made for the purpose of providing a still video camera that solves the above-mentioned problems, and is compact, has excellent portability, and can be held in a stable posture.
To provide a still video camera with a short finder optical path and in which a video floppy disk or a simple circuit board with a large area can be easily installed.

[Structure of the invention]

The camera body is a flat rectangular parallelepiped whose width and length are larger than its height, and its upper and lower surfaces are shifted back and forth in the longitudinal direction, so that the front and bottom surfaces and the back and top surfaces intersect at acute angles. They each have a shape with surfaces that are perpendicular to the front and rear surfaces, and one side is the part that is gripped by hooking your fingers on the top and bottom surfaces. The present invention is a still video camera characterized by a viewfinder protruding from the rear, and this configuration achieves the above object.

(Example) The present invention will be explained below with reference to the example shown in FIGS. 1 and 2.

In FIG. 1.2, the same reference numerals as in FIGS. 3 to 5 indicate the same functional parts; 5 is a floppy drive, 6 is a photoelectric conversion element, 7 is a circuit board, and 8 is a tripod mount.

In the still video camera of the present invention, the front surface where the photographing lens 3 is provided intersects with the top surface at an obtuse angle. When gripping and holding, the elbows will be closer to the body,
Therefore, the posture of holding the camera is stable, and the photographer is less likely to get tired.

The angle at which the front surface and the top surface intersect is preferably such that θ shown in FIG. 2 is approximately 20°. Further, it is preferable that the grip portion 1 is provided with a surface member made of rubber, leather, etc., which is easy to grip and is non-slip.

Since the finder is provided protruding from a surface perpendicular to the rear surface, the optical path is short (and the optical system is simple, easy to design and manufacture, and there is no waste in terms of volume. In other words, it is suitable for still video cameras. This finder may be fixed, but it is more convenient to carry if it can be sunk in a plane orthogonal to the rear surface.

Furthermore, since the still video camera of the present invention has a flat box-shaped camera body, it is easy to mount the floppy drive 5 and the simple-shaped circuit board 7 with a large area and high packaging density, as shown in FIG. Can be placed. It is also possible to provide a screw hole for a tripod on a surface perpendicular to the front surface and connect it to a tripod mount 8, as shown in FIG.

As described above, the still video camera of the present invention is compact and has excellent portability, can be held in a stable position so that the photographer does not get tired, has a short finder optical path, and does not require a large video floppy disk or area. This has the effect that a large circuit board with high packaging density can be easily arranged.
