Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording / reproducing apparatus having a so-called camera-integrated recording / reproducing function in which a camera mechanism section and a recording / reproducing mechanism section are integrally incorporated.

[0002]

2. Description of the Related Art Conventionally, in this type of recording / reproducing apparatus, the camera mechanism is designed so that the optical axes of the front lens and a plurality of lens groups are arranged linearly and horizontally. As a set mounting form of the camera mechanism unit and the recording / reproducing mechanism unit described above, the following arrangement structure is generally used. A so-called video camera device in which the camera mechanism unit and the VTR mechanism unit that is the recording / reproducing mechanism unit are integrated in this recording / reproducing apparatus will be described.

FIG. 6 shows a system in which a camera mechanism section and a VTR mechanism section are arranged in parallel. That is, the camera mechanism unit 30
Are arranged in parallel on the rear surface side of the chassis 42 of the mechanical deck 41 of the VTR mechanism unit 40 in a state where the optical axes of the front lens 31 and the plurality of lens groups 32 are linearly arranged.

FIG. 7 shows a system in which the camera mechanism section and the VTR mechanism section are arranged in a straight line. In this case, the camera mechanism unit 30 is linearly arranged on one front side of the mechanical deck 41 of the VTR mechanism unit 40 in a state where the optical axes of the front lens 31 and the plurality of lens groups 32 are linearly arranged. ing.

[0005]

In the above-described set mounting form of the video camera device, the parallel arrangement method shown in FIG. 6 has an advantage that the size of the video camera device in the longitudinal direction can be shortened. As for the size in the width direction, a space that adds the width size of the mechanical deck and the lens size is required, and the size in the width direction is a thick type design. That is, since the size of the tape cassette and the size of the lens used in the mechanical deck are determined by the specifications of their optical performance, it is difficult to make the size in the width direction thin.

Further, the linear arrangement system shown in FIG. 7 has an advantage that the size of the video camera device in the width direction can be made thin, but on the other hand, the size in the length direction is the total length of the camera mechanism and the VTR. A space is required that is added to the total length of the mechanical section, and therefore the size in the length direction is designed to be long.

Although not shown as another method, in the case where the camera mechanism is set on the upper part of the VTR mechanism, it is not shown in FIG.
Similarly, the size of the video camera device in the width direction can be made thin, but the size in the height direction is large.

The present invention has been made in order to solve the above-mentioned problems, and it is a conventional camera mechanism and VTR.
While having the same specifications as the mechanical part, the width size, length size, and height size of the video camera device can be reduced, and downsizing can be achieved as a whole, and at the same time, a new design can be achieved. The purpose is to obtain a recording / reproducing apparatus.

[0009]

In order to achieve the above object, a recording / reproducing apparatus according to the present invention is a recording / reproducing apparatus in which a camera mechanism section and a recording / reproducing mechanism section are integrally incorporated, and the camera mechanism section is a front lens. An optical means for bending the optical axis of the subject light incident from the lens in a direction perpendicular to the optical axis, and a solid-state image sensor for converting the subject light emitted from the optical means to go straight through a plurality of lens groups and to be emitted into an electric signal. Is
The optical axis directions of the lens groups of the camera mechanism section are arranged in parallel on one surface of the recording / reproducing mechanism section.

With this configuration, the camera mechanism section causes the subject light incident from the front lens to be refracted by the optical means in the direction perpendicular to the optical axis to pass through the plurality of lens groups,
The emitted subject light can be output as an electric signal by the solid-state image sensor. Therefore, by arranging the optical axis direction of the lens group of the camera mechanism section on one surface of the recording / reproducing mechanism section in parallel, the recording / reproducing apparatus can be downsized.

Further, in the recording / reproducing apparatus of the present invention, the optical axis directions of the lens groups of the camera mechanism section are arranged vertically in parallel on one surface of the recording / reproducing mechanism section, so that By reducing the size in the front-rear length direction, the recording / reproducing apparatus as a whole can be downsized.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a recording / reproducing apparatus according to the present invention will be described below with reference to the drawings by taking as an example a video camera apparatus in which a camera mechanism section and a VTR mechanism section are integrated.

FIG. 1 shows a camera mechanism unit 1 and a VTR according to this embodiment.
It is a schematic perspective view with the mechanism part 2. In FIG. 1, reference numeral 3 is a camera mechanism housing that houses the camera mechanism unit 1 and is integrated, and the internal configuration of the camera mechanism housing 3 is shown in FIG.

In FIG. 2, the camera mechanism section 1 constitutes a zoom lens. This zoom lens is proposed by the applicant of the present invention in Japanese Patent Application No. 7-48665, and a detailed description thereof will be omitted here, and a main structure will be described.

The zoom lens comprises, in order from the subject side, a first lens group 10 having a positive refractive power, a second lens group 11 having a negative refractive power, a diaphragm 12, and a third lens having a positive refractive power. It is composed of a group 13 and a fourth lens group 14 having a positive refractive power. The first lens group 10 sets the optical axis of the subject light incident from the front lens 15 to the lens 15 concerned.
The prism 16 arranged on the back side of the optical axis refracts at a right angle (vertical direction in the embodiment). Therefore, the optical axis L refracted at a right angle by the prism 16 then goes straight through the second lens group 11, the diaphragm 12, the third lens group 13 and the fourth lens group 14 and is transmitted therethrough.

On the other hand, the first lens group 10 and the second lens group 1
Reference numeral 1 constitutes a variable power system, and a variable power operation is performed by moving the second lens group 11 in the optical axis direction. Also, the fourth
By moving the lens group 14 in the optical axis direction, the focal position is adjusted when the magnification is changed and the subject distance is changed. And
The subject light emitted from the fourth lens group 14 is input to a solid-state image sensor (CCD) 18 via an optical filter 17, and is converted into an electric signal here.

Incidentally, the above-mentioned camera mechanism section 1 is a prism 1.
Since 6 is used, the subject optical path incident from the front lens 15 is reflected by the prism 16 and the subject information is horizontally inverted. Therefore, in order to correct this, the output signal from the solid-state image sensor 18 is horizontally inverted again using the existing memory circuit and output as a normally rotated signal.

A schematic structure of the VTR mechanism unit 2 will be described with reference to FIG. A wiring board 21 is arranged on the back side of the mechanical chassis 20 that constitutes the base body of the VTR mechanism section 2, and a cassette compartment (hereinafter, referred to as "cassette") 22 is arranged on the front side of the mechanical chassis 20. It is configured as an integrated type. Although not shown, a rotary drum having a magnetic head, a tape loading mechanism, a tape running mechanism, and the like are arranged in the cassette computer 22, and the tape cassette can be attached and detached.

The above-mentioned camera mechanism section 1 and VTR mechanism section 2
1 will be described with reference to FIG.
The camera mechanism unit 1 is arranged on the flat front side surface 2 a of the TR mechanism unit 2. More specifically, the flat front side surface 2a of the VTR mechanism unit 2 means the front side surface when the cassette computer 22 is located on the right side when the video camera device is held by the right hand. On the front side surface 2a of the VTR mechanism portion 2, the vertical optical axis is arranged in parallel with the front lens 15 of the camera mechanism portion 1 facing forward.

Then, in such a set mounting state, the camera mechanism section 1 and the VTR mechanism section 2 are housed in a cabinet 23 which is a casing. The camera mechanism 1 and the VT
The R mechanism section 2 is a wiring board 2 of the mechanical chassis 20 in which the flexible wiring board 18a pulled out from the solid-state image sensor 18 is
Connected to 1.

As described above, in the video camera device of the present invention, in the camera mechanism section 1, the subject light incident from the front lens 15 is refracted by the prism 16 in the vertical direction of the optical axis and transmitted through each lens group. Since the object light emitted by the solid-state imaging device can be output as an electric signal, the depth length of the camera mechanism unit 1 is substantially equal to the depth length H of the VTR mechanism unit 2. Lens 15
Since the distance from the prism 16 to the prism 16 is H ₁ , the length of the camera mechanism unit 1 can be greatly shortened, and the overall size of the video camera device can be greatly shortened. Moreover, since the width and height of the video camera device can be substantially accommodated within the width and height dimensions of the video mechanism unit 2, it becomes possible to reduce the above-mentioned total length size and to make the video camera device thinner. As a whole, it can be made compact and have a novel appearance design.

Further, in the above-mentioned set mounting form, as shown in FIG. 3, by disposing, for example, a swivel type liquid crystal display panel 24 on the side of the wiring board 21 of the VTR mechanism section 2, a video camera with a conventional liquid crystal display panel is arranged. Further miniaturization can be realized as compared with the device.

FIG. 4 shows another example of a set mounting mode of the camera mechanism section 1 and the VTR mechanism section 2. According to this, VT
The R mechanism unit 2 is V in the state where the cassette computer 22 is on the back side, that is, when the cassette computer 22 is facing the photographer,
The camera mechanism unit 1 is arranged on the flat right side surface 2b of the TR mechanism unit 2 with the front lens 15 thereof facing forward and with the vertical optical axes parallel to each other.

By adopting such a set mounting mode,
Although the width direction of the VTR mechanism unit 2 is slightly widened by the width of the camera mechanism unit 1, a video camera device can be obtained which is further thinned in the depth direction. Incidentally, also in this set mounting mode, by disposing, for example, a swivel type liquid crystal display panel on the wiring substrate 21 side, it is possible to realize a further reduction in thickness as compared with a conventional video camera device with a liquid crystal display panel.

The present invention is not limited to the embodiments described above and shown in the drawings, and various modifications can be made without departing from the scope of the invention.

In the embodiment of the present invention, the camera mechanism unit 1 is a VT.
Although the video camera device integrated with the R mechanism unit 2 has been described, it goes without saying that the VTR mechanism unit can be widely applied regardless of whether the recording / reproducing is an analog signal or a digital signal.

For example, when the recording / reproducing system of the VTR mechanism section is a digital signal, the size of the cassette to be used is about half that of the conventional 8 mm video cassette, and therefore, as shown in FIG. The VTR mechanism section shown can be further downsized and its shape can be freely designed. Therefore, a more compact video camera device can be obtained by adopting a set mounting mode in which the optical axis direction of the camera mechanism unit 1 is vertically arranged on the VTR mechanism unit 25.

Further, it can be widely applied to the recording / reproducing mechanism other than the VTR mechanism, and for example, the recording / reproducing medium of the recording / reproducing mechanism may be a disk.

In any case, even if the shape of the recording / reproducing mechanism section is different, by setting the curved lens optical axis of the camera mechanism section in parallel on one surface of the shape, the conventional configuration is adopted. It is possible to make it compact while having the same specifications as the camera mechanism section.

Further, the camera mechanism section can be rotated so that the lens optical axis of the camera mechanism section can be changed vertically or horizontally with respect to the recording / reproduction mechanism section depending on the convenience of use of the recording / reproduction apparatus. It is also within the scope of the present invention.

[0031]

As described above, the recording / reproducing apparatus of the present invention is a recording / reproducing apparatus in which a camera mechanism section and a recording / reproducing mechanism section are integrally incorporated, and the camera mechanism section detects the subject light incident from the front lens. An optical unit that bends the optical axis in a right-angled direction and a solid-state image sensor that converts the subject light emitted from the optical unit by going straight through a plurality of lens groups to an electric signal, By arranging the lens groups of the camera mechanism section in parallel with each other on the one surface, there is an effect that the recording / reproducing apparatus as a whole can be made compact, and the degree of freedom can be increased while having a novel appearance design.

Further, since the optical axis directions of the lens groups of the camera mechanism section are arranged vertically in parallel on one surface of the recording / reproducing mechanism section, the size of the recording / reproducing apparatus in the width direction and the length direction is reduced. It is possible to reduce the size of the recording / reproducing apparatus as a whole.
