Abstract

PURPOSE:To improve operability and function due to the lightening of an operating part by using the recorder even when a camera part having a lens, an image pick-up part and the like is separated from a video tape recorder main body recording part. CONSTITUTION:At a camera part 1, the operation mechanism to execute the operation necessary at the time of photographing is fitted, and the operation to direct an image pickup part 12 in the subject and the photographing direction, the zoom operation, the photographing starting, the stoppage operation and the like are executed. Since these operating parts are provided on a camera, it is not necessary to direct a tape travelling part 36 and a signal processing part 31 toward the subject and they are may exist at a recording part 3, the part is electrically connected by a connecting cable 2 of the suitable length at the time of separation. Consequently, when the user photographs while the user moves, the recording part 3 is installed to a waist, shoulder and the like and only the camera part 1 can be photographed on hand. Thus, the operability and the function due to the lightening of the operating part can be improved.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a camera-integrated videotape recorder.
In particular, the present invention relates to a camera-integrated videotape recorder that improves operability by reducing the weight of the parts that require all operations for photographing.

[Conventional technology]

In recent years, the technology of recording on a video tape recorder using a video camera has been developed, for example, as shown in Figure 9 of TV Technology, August 1985 issue, page 26. The camera and recorder sections are moving from being independent to integrated cameras. especially.

Although it has stopped, it has become very popular for home use.However, since such camera-integrated video tape recorders are generally used while moving, the problem of weight reduction was important.

[Problem to be solved by the invention]

The above-mentioned conventional technologies for reducing the weight of video tape recorders with built-in cameras have mainly focused on reducing the size of the tape, simplifying the lens function, and reducing the weight of the battery, but all of these techniques have reduced the recording time, image quality, etc. The decision is made based on functionality, such as recording time and image quality. There was no consideration given to reducing weight and improving operability while retaining the camera and using conventional parts as is.

Therefore, it is an object of the present invention to overcome the problems of the prior art.
To provide a camera-integrated videotape recorder which is not limited by tape or recording time and has improved operability by reducing the weight of an operating section.

[Means to solve the problem]

In order to achieve all of the above objects, the camera-integrated video tape recorder of the present invention is configured so that the camera section including a lens, an imaging section, etc. can be used even if it is separated from the video tape recorder main body (recording section).

As a specific configuration, the camera section includes a sound receiving section consisting of a microphone or the like. In addition, a connection cable is provided that electrically connects the camera section and the video tape recorder main body to enable use during separation.

[Function] The camera gK is equipped with an operating device f# that performs necessary operations when taking pictures.
I am installing it. Necessary operations include an operation to orient the imaging section (light receiving section) toward the subject or direction to be photographed, a zoom operation, and an operation to start and stop photographing. These operation units are provided on the camera.

The tape running section and the signal processing section do not need to be directed toward the subject; they only need to be located in the recording section. When separated, an electrical connection is made using a connection cable of an appropriate length, so that when the user is taking pictures while moving, the user can wear the recording section on his or her waist or shoulder and only use the light receiving section (camera section). It becomes possible to shoot completely handheld.

〔Example〕

Hereinafter, one embodiment of the present invention will be explained with reference to FIG.

In the figure, 1 is the light and sound receiving section (camera section), 5 is the recording section (VTR main body), and 2 is all the connection cables used when operating separately. In the light-receiving and sound-receiving section 1, the received image is transmitted to the lens 11. After passing through the aperture (not shown) and converting it into an electrical signal at the imaging section 12, it is sent to the recording section 3 via the preamplifier 16° connection cable 2.
added to.

In the recording section B, the video signal is processed by the video signal processing section 31.
, a video recording amplifier 62, and then recorded on a magnetic tape 57 by a video head 56. It goes without saying that there are no particular restrictions on the division of the preamplifier 15 and the video signal processing section 51 as long as it does not affect the signal qi at all.

On the other hand, when photographing, it is desirable that the sound receiving section also be directed toward the photographing direction, so the light receiving section may also include the sound receiving section. In this case, the audio signal converted into an electrical signal by the microphone 14 is amplified by the preamplifier 15iC, and then connected to the connecting cable 2 through 9 and the audio recording amplifier 54 f!
: Then, the audio head 55 records on the magnetic tape 57. Needless to say, in the case of audio signals, there are no particular restrictions on the division between the preamplifier 15 and the audio recording amplifier 54. In addition, there are cases in which an audio signal is recorded without using the dedicated audio signal radar 65, or at the same time as being superimposed on a video recording signal. Incidentally, since the recording section generally includes a tape running mechanism and its control section, this is indicated by 36.

In the figure, the connection cable 2 is configured such that the light receiving and sound receiving section 1 can be stored in either of the recording sections B when not separated, and is pulled out when separated. In addition, the connection cable 2 is detachable and is used only when separated, and when not separated, it can directly receive light and sound from the sound receiving part 1 without using the connection cable.
It is also possible to adopt a configuration in which a 5ft recording unit can be connected to the recording unit. Furthermore, a wireless method using radio waves or the like is also possible as a signal transmission means during separation.

In addition, depending on the usage conditions, the light receiving and sound receiving parts may be
It can also be used in combination with a different type of camera and a VT Rt. For example, the same camera part (light receiving and sound receiving part)
In contrast, standard cassette tape and C
It also becomes possible to use different recording sections of the cassette tape.

The light-receiving and sound-receiving sections have a part of the operation section, such as zoom operation, so that when used separately, the light-receiving and sound-receiving sections can perform operations necessary for photographing.

〔Effect of the invention〕

According to the present invention, depending on the usage conditions of the camera-integrated videotape recorder, the light receiving section and the recording section can be used either as an integrated unit or separately, and operations can be performed according to the situation. It has excellent effects such as improved functionality.
