Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a recorder with a camera.

[Prior Art] Conventionally, in a camera using a so-called silver salt film as a recording medium, the optical axis of the imaging lens and the exposed surface of the film, which is the recording medium, must be orthogonal to each other in principle.

FIG. 5 is a diagram showing the general structure of a camera using a silver salt film as a recording medium. As shown in the figure, the subject image from the taking lens 111 is placed on the exposed surface of the film 114 arranged so as to be orthogonal to the optical axis 115. Will be recorded. In this way, when the exposure surface of the film 114 is arranged to be orthogonal to the optical axis, the camera main body 112 is arranged as shown in FIG. 5 in order to store the film cartridge 113 in a space-free manner. I have no choice but to. That is, the widest end surface of the camera body 112 has a structure orthogonal to the optical axis.

In recent years, even cameras using such a silver salt film as a recording body have various structures, but as long as they have a structure in which the exposed surface of the film is orthogonal to the optical axis, There is basically no difference from the structure.

On the other hand, in recent years, various recorders with a camera that convert optical information into an electric signal and record the signal on a recording medium have been developed. In particular, a so-called camera-integrated video tape recorder (hereinafter referred to as a camcorder) that uses a magnetic tape as a recording medium. Called) is becoming popular.

6 (A) and 6 (B) are views showing the most general structure of the camcorder. FIG. 6 (A) is a left side view and FIG. 6 (B) is a right side view. In the figure, 101 is a lens unit that holds and drives a lens group that is a photographing optical system, and 102 is a lens unit 1.
A camera unit that converts optical information incident through the lens group in 01 into an electric video signal, and a recorder unit 103 that records the video signal from the camera unit 102 on a magnetic tape. The lens unit 101, the camera unit 102, and the recorder unit 103 are generally arranged in a straight line as shown in the drawing. In the figure, 104 is an electronic viewfinder (EV) that displays a video signal recorded by the recorder unit 103.
Part F) and 105 are grips for the photographer to hold the camcorder.

Here, the outline of the configuration of the camcorder will be described with reference to FIG. The light receiving surface of the image sensor 202 in the camera unit 102 needs to be orthogonal to the optical axis of the lens unit 101. A subject image is formed on the image pickup element 202 via the lens group 201 in the lens unit 101. An electric signal corresponding to the subject image is output from the image pickup element 202, and the camera signal processing circuit 203
Is supplied to. The circuit 203 converts the electric signal into a video signal of a predetermined form and outputs it. The video signal output from the circuit 203 is electrically supplied to the recorder 205 and the EVF 204, and the recorder 205 records the data on the magnetic tape and outputs the EVF.
In 204, it is displayed on the display as a visible image.

The photographer operates the operation panel 207 while confirming the image to be captured by the EVF 204. The data indicating the operation content of the operation panel is broken down by the system control microcomputer 208 into a command indicating the specific processing content, and then supplied to each part of the apparatus. Especially recorder 205
To at least the instruction to start recording and end recording,
In response to this, the recorder 205 records the above-mentioned video signal. Of course, the recorder 205 and EVF 204 in FIG. 7 are included in the recorder unit 103 and EVF unit 104 in FIG.

[Problems to be Solved by the Invention] As described above, in the camcorder, the structure and arrangement of each part other than the direction of the light-receiving surface of the image sensor 202 can be freely set, so that the camcorder has more structural freedom than a camera using a silver salt film. The degree is high. However, the conventional camcorder does not fully utilize this degree of freedom, and is far from an ergonomically optimal structure. For example, the camcorder shown in FIGS. 6A and 6B has the following drawbacks.

FIG. 8 shows the first part of the camcorder shown in FIGS. 6 (A) and 6 (B).
FIG. 6 is a diagram for explaining the problem of FIG. When the image-capturing person 150 takes an image, the smaller the angle θ1 formed by the elbow and the angle θ2 formed by the torso and the upper arm, the more stable the image can be held without shaking.
In practice, the minimum value of the angle formed by the elbow joint is within 30 °, so θ1 = θ2 = 30 ° is preferable. However, in the camcorder having the structure shown in FIGS. 6 (A) and (B),
Since the distance between the grip 105 and the eyepiece of the EVF unit 104 is large, θ1 and θ2 become large as shown in FIG. 8, and stable holding cannot be expected. Furthermore, as shown in FIG.
In the structure of (B), the recorder 103 is placed close to the front of the photographer, which gives the photographer a cramped feeling and avoids contact between the photographer's nose and the recorder 103. Considering points and the like, the distance between the recorder unit 103 and the eyepiece of the EVF unit must be further increased, and the above θ1 and θ2 are further increased.

FIG. 9 shows the second part of the camcorder shown in FIGS. 6 (A) and 6 (B).
6A and 6B are diagrams for explaining the problems of FIG.
The common number is used. FIG. 9 shows FIG. 6 (A),
It is a front view of the camcorder shown in (B), and the center of gravity G of this camcorder is shown in the figure. On the other hand, since the photographer holds the camcorder with the grip 105, a force acts on the wrist of the photographer in the direction indicated by the arrow V. This corresponds to the force of bending the wrist inward, which imposes a heavy load on the photographer and hinders stable holding.

As described above, the conventional recorder with a camera does not have an ergonomically preferable structure, although it has a structure that can take a free structure. It was The present invention solves such a problem,
It is an object of the present invention to provide a recorder with a camera which is ergonomically excellent, can maintain stability, can photograph a good image without blurring, and can minimize the fatigue of the photographer.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a camera for converting optical information obtained from an imaging optical system into an electric signal, and a recorder for recording the electric signal on a recording medium. Is a recorder with a camera that can be handled integrally, and a recorder housing that includes at least a part of the recorder behind a camera housing that includes at least a part of the camera on a horizontal plane when the image is taken by the camera. And a longitudinal direction of the recorder housing is arranged to be inclined with respect to the optical axis of the optical system, and a finder is provided on the side where the subject side end of the recorder housing is located with respect to the optical axis. At the same time, a grip is provided on the side of the camera housing of the recorder housing on which the photographer side end portion is located, and the grip is provided on the side of the recorder housing where the photography side end portion is located. The center of gravity of the coder housing is located and configured.

[Embodiment] The structure of a recorder with a camera as the most preferred embodiment of the present invention will be described below with reference to FIG.

In FIG. 1, a solid line shows a schematic construction of a camcorder as an optimum embodiment of the present invention, and a dotted line shows that of a conventional camcorder of the same physical scale. FIG. 1 is a schematic view of the camcorder as seen from above, in which 1 is a lens unit, 2 is a camera unit housing, 3 is a recorder unit housing, and as shown in the drawing, the recorder unit housing 3 is on a horizontal plane at the time of shooting. The longitudinal direction (indicated by the one-dot chain line z in the figure) in the drawing was tilted with respect to the optical axis of the lens unit 1 (indicated by the one-dot chain line x in the figure). However, the image pickup device in the camera body 2 is arranged orthogonal to the optical axis x, and the configuration itself is no different from the conventional example of FIG.

By setting the layout of the recorder housing 3 in this manner, various conventional problems can be solved. First,
When the EVP unit 4 is installed on the recorder housing 3, the eyepiece unit 41
Will approach the grip 5. On the other hand, the center of gravity is from G1
Although the grip 5 is moved along with the movement to G2, the movement of the eyepiece 41 is 1 → l2, while the movement of the grip 5 is l3 → l4, and the eyepiece 41 is moved. Part 41
Since the moving distance of the grip 5 is smaller than the moving distance of, the distance between the eyepiece 41 and the grip 5 becomes short as a result.

In order to simply bring the grip 5 and the eyepiece 41 closer to each other, an arrangement in which the longitudinal direction z of the recorder housing 3 is orthogonal to the optical axis x can be considered. However, in this case, the EVF unit 4 must be arranged so as to project from the recorder housing 3 toward the photographer. This takes into account the above-mentioned cramped feeling of the photographer and the contact between the nose and the recorder housing 3. In addition, the mounting position of the grip 5 is inevitably closer to the lens side, and the distance between the grip 5 and the eyepiece portion is not so short after all. Besides, grip 5
Since the lens is attached to the lens unit 1 in the vicinity, the position in the optical axis x direction does not coincide with the center of gravity.

In the example of FIG. 1, with the optical axis x and the longitudinal direction z of the recorder housing 3 being tilted as described above, the EVF unit 4 is a preferred embodiment of the present invention in which the EVF section 4 is attached to the recorder housing 3 with respect to the optical axis x. It is provided on the side where the subject side end 3a is located (left side in the figure). As a result, the eyepiece part 41 of the EVF part 4 comes closer to the grip 5 in the optical axis x direction. Further, at this time, since the center of gravity of the recorder housing 3 is located on the side of the photographer side end portion 3b of the housing 3 (right side in the figure), the center of gravity of the entire camcorder is closer to the photographer side. And the eyepiece 41 is the optical axis x
You can get closer in direction. Here, the grip 5 and the eyepiece 41 are separated from each other in the direction orthogonal to the optical axis x, but this is closer to the positional deviation amount between the eye position and the shoulder position in the same direction, so rather. It is preferable.

Further, as described above, the optical axis x and the longitudinal direction z of the recorder housing 3 are set.
Is inclined, as a preferred embodiment of the present invention, the center of gravity of the casing 3 is located on the side where the photographer side end 3b of the recorder casing 3 is located with respect to the optical axis x. Approach the grip 5 side. Therefore, the force in the direction indicated by the arrow v in FIG. 9 can be reduced, and the burden on the photographer is further reduced.

Hereinafter, a structural example of a camcorder embodying the above idea will be described. 2 is a top view of a camcorder as an embodiment of the present invention, FIG. 3 is a side view thereof, and FIG. 4 is a rear view thereof.

A grip switch 5 in FIG. 3 has a trigger switch 31 for instructing start and end of photographing, a telescopic (tele) instruction switch for changing the angle of view of the lens unit 1, and a wide-angle (wide) instruction. A switch is provided. The recorder housing 3 has a switch panel (operation panel) 32,
There are provided a fast-forward button 321, a playback button 322, a rewind button 323, a stop button 324, and a recording button 325, which are well known in.
The instructions from these switches are transmitted to the control microcomputer by the electrical processing similar to the conventional one, and each part of the device is controlled.

In FIG. 3, a lens driving actuator for focusing, adjusting an angle of view (focal length), and the like is arranged in a cover 11 below the lens unit 1.

In FIG. 4, 34 is a mounting portion of the video tape cassette, and the EVF portion 4 and an eyecup 41 which is an eyepiece portion of the EVF portion 4 are located above the mounting portion.

The above-described embodiment has been described with respect to a camcorder that is held by the right hand and looks into the finder with the right eye.
The same effect can be expected if the arrangement is left-right opposite to the optical axis.

Although EVF is used as the finder, the same effect can be expected in a configuration using an optical finder. However, in the case of an optical finder, it is difficult to set the optical path with a large deviation from the optical axis, and therefore it is desirable to place it near the optical axis.

Further, in the above-described embodiment, the camera unit housing and the recorder unit housing are separately provided. However, even in a device in which the camera unit housing and the recorder unit housing are commonly used, the horizontal plane of the common housing is used. The same effect can be obtained by inclining the upper longitudinal direction with respect to the optical axis.

Furthermore, the case where the lens unit, the camera unit, and the recorder unit are always integrally combined has been described, but the present invention is applied to a device in which the lens unit can be attached to the camera unit and a device in which the camera unit can be attached to and detached from the recorder unit. Even if it applies, the same effect is obtained. That is, the present invention is effective at least when applied to a device that handles a recorder unit and a camera unit including a lens unit in a coupled state at the time of photographing.

Further, in the above-described embodiment, the camcorder using the magnetic tape as the recording medium has been described as an example, but the same effect can be obtained by applying the present invention to a so-called electronic still camera which records a still image using a magnetic floppy disk.

[Effects of the Invention] As described above, according to the present invention, it is possible to obtain a recorder with a camera that has an excellent ergonomic structure, can be particularly stably held, and can perform good shooting without camera shake. it can.

Further, the size of the recorder with camera in the optical axis direction can be reduced.
