It is recorded above. According to the conventional example 1, at the time of photographing, the photographing is performed such that the photographing is performed in such a manner as to face the subject along the optical axis of the lens barrel (3). Was located on the front side.

6 and 7 are a side view and a front view showing another conventional camera-integrated video tape recorder, wherein (1) is a lens system, (2) is an image sensor, and (3) ) Is the lens system (1) and the image sensor (2)
(9) is a tape cassette, (12) is a VCR, (13) a viewfinder, and (4) incorporates the VCR (12). This is a housing that holds the viewfinder (13) (conventional example 2). According to the conventional example 2, the lens barrel (3) is disposed on the side surface of the housing (4).
In the same manner as in the conventional example 1 shown in FIG. 5, the optical axis is taken in the direction of the subject.

[Problems to be solved by the invention]

As described above, according to the camera-integrated video tape recorders of Conventional Example 1 and Conventional Example 2, in the case of Conventional Example 1, the video deck section is arranged in a substantially rectangular shape, whereas the lens barrel is used for shooting. However, since the optical axis is arranged so as to face the direction of the subject and is arranged in front of the video deck section, there is a problem that the overall length is long and the irregularities of the outer shape are increased. On the other hand, in the case of Conventional Example 2, since the lens barrel is disposed on the side surface of the VCR, the thickness in the width direction is increased, and there is a problem that portability and storage are deteriorated.

The present invention has been made in order to solve the above-described problems, and has been made to provide a camera-integrated video tape recorder that has good portability and storability while reducing unevenness of the outer shape and eliminating useless space in a housing. The purpose is to provide.

[Means for solving the problem]

In order to achieve the above object, in the present invention, the lens barrel is
The optical axis is oriented so as to be substantially perpendicular to the direction of the subject, and is arranged close to the VCR, and the light from the subject is reflected at a right angle to the front position of the lens barrel. And a mirror that is made incident on the lens barrel so as to be openable and closable.

[Action]

According to the present invention, since the lens barrel is arranged so that the optical axis thereof is substantially perpendicular to the direction of the subject and close to the video deck, the overall length of the product itself is reduced.
Also, since a mirror that reflects light from the subject at a substantially right angle and enters the lens barrel is provided at the front position of the lens barrel so as to be openable and closable, when the camera is not used, the mirror is closed. In addition, the outer shape is not uneven, and it is a compact form.

(Example of the invention)

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

1 and 2 are a configuration diagram and a partially cutaway perspective view showing a camera-integrated video tape recorder showing an embodiment of the present invention. In the figure, (1) is a lens system,
(2) is an image sensor, (3) is a lens barrel holding the lens system (1) and the image sensor (2), (4) is a housing holding the lens barrel (3), and (5) is A mirror that reflects light from a subject at a substantially right angle (approximately 90 °) and enters the lens barrel (3). This mirror has one end serving as a rotation axis with respect to the housing (4). It is provided in the form of a door which can be opened and closed freely by opening and closing means. (6) means for detecting the opening and closing of the mirror (5), (7) dustproof glass fixed to the housing (4) in front of the lens barrel (3), (8) an image processing circuit, 9) is a tape cassette, (10) is a magnetic tape, (11) is a rotary head, (12) is a video deck section including the tape cassette (9) and the rotary head (11), and (13) is a viewfinder. It is.

Specifically, the mirror (5) is in a closed state when the camera is not used (when carrying or storing), as shown in FIG. 3, and when the camera is used (when photographing). Is the fourth
As shown in the figure, it is configured to open to a predetermined opening degree. For example, if the mirror (5) is opened during photographing (when the camera is used), this open state is detected by the open / close detecting means (6), and the power is turned on to the camera-integrated video tape recorder. Conversely, when the mirror (5) is closed when stored or carried after photographing (after using the camera), the closed state of the mirror (5) due to the cap function is detected by the open / close detection means (6).
The power of the camera-integrated video tape recorder is turned off.

As shown in FIG. 1, the mirror (5) reflects light from a subject (not shown) at an angle of substantially a right angle (90 °), and is arranged substantially perpendicularly to the direction of the subject. It goes without saying that the opening is set at an angle such that the light is incident on 3), and this opening is secured during photographing.

 Next, the operation of the above configuration will be described.

Open the mirror (5) and look at the target subject (not shown) by looking through the viewfinder (13). The light from the subject is first optically focused by a lens system (1), and is converted into electrical information by an image pickup device (2) such as a CCD holding the optical image at a focused position. The optical image formed on the image sensor (2) is different from the optical image obtained by directly forming light from the subject by the lens system (1).
Since the image from the light from the subject is once reflected by the mirror (5), it is a mirror image that is inverted upside down. Next, the image processing circuit (8) sequentially reads the electrical information from the image sensor (2) in an upside-down order in which the normal image processing circuit reads (scans) the electrical information from the image sensor (2). ,
Reads out and creates an NTSC image signal. Finally, in the video deck section (12), the image signal is recorded on a magnetic tape (10) drawn from a tape cassette (9) by a rotating head (11).

According to the camera-integrated video tape recorder exemplified in the above embodiment,
Since the mirror can be folded, it has a box-shaped outer shape with less unevenness, and has an effect that a camera-integrated video tape recorder excellent in portability and storage property can be obtained.

〔The invention's effect〕

As described above, according to the present invention, when stored and carried, the mirror is configured to be openably and foldably folded, so that not only the box-shaped outer shape with little unevenness but also the lens barrel and the video It is possible to reduce the dead space between the decks and eliminate the useless space in the housing, and it is possible to obtain a novel and beautiful design with excellent portability and storage.
