Abstract

PURPOSE:To easily identify to which mode of the recording mode or the temporary stop mode a tape recorder is switched at the time of depressing an operational button by providing a pronouncing means capable of aurally identifying which of said two modes does the depressing corresponds to. CONSTITUTION:If the operational button 6 is depressed, a mode switching circuit 7 changes the video tape recorder 5 into the recording mode, and the pronounsing circuit 8 operates to drive a pronouncing body 9 to generate a sound. Then, if the button 6 is depressed again, the circuit 7 changes the tape recorder 5 into the temporary stop mode, at which time the pronouncing body 9 does not operate. Thus, there is the sound generated at the time of changing the recorder 5 into the recording mode, but there is no sound when changing into the temporary stop mode, therefore, an operator can easily identify to which mode the recorder 5 is to change into when a person depresses the operational button 6. Of course, the sound-generation can be inversed so that there is no sound at the time of switching to the recording mode but the pronouncing body 9 is driven to made a sound at switching to the temporary stop mode.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a video camera for taking pictures.

2. Description of the Related Art A conventional video camera will be described below with reference to the drawings. FIG. 3 is a diagram showing the main parts of a conventional video camera. A lens 2 for photographing a subject is placed at the front of the video camera body 1, and an optical image formed by this lens 2 is formed on an image sensor 3. image and converted into an electrical signal. This electrical signal is supplied to the signal processing circuit 4 and converted into a predetermined video signal.

This video signal is supplied to a video tape recorder 5 for recording photographed images. The operation button 6 is for switching the operation mode of the video tape recorder 5, and as is well known, when pressed once, the operation button 6 changes the operation mode of the video tape recorder 5.
The next press will switch to the pause mode.

Problems to be Solved by the Invention However, in the above configuration, as the operator repeatedly presses the operation button 6, it is difficult to determine whether the next press corresponds to the recording mode or the pause mode. It becomes difficult to determine whether Normally, a light emitting diode or the like is turned on in response to one of the Li types, but there is a problem in that it is difficult to distinguish them outdoors in bright light. There is also the problem of erroneous operation, in which the user presses the operation button 6 without realizing it when carrying a video camera, resulting in unnecessary recording.

The present invention provides a video camera that solves the above problems.

Means for Solving the Problems In order to solve the above problems, the video camera of the present invention has an operation button that allows the video tape recorder to repeat the operation mode between a recording mode and a pause mode by repeatedly pressing the button. The apparatus is further provided with a sounding means that can audibly identify whether the pressing operation of the operation button corresponds to a recording mode or a pause mode.

Operation The present invention differs from conventional video cameras in that it has the above-described configuration, and allows auditory identification of whether the pressing operation of the operation button corresponds to a recording mode or a pause mode.

Embodiment A video camera according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram illustrating the operation of a video camera according to an embodiment of the present invention.

When the operation button 6 is pressed, the mode switching circuit 7 changes the video tape recorder 5 to the recording mode, and the sounding circuit 8 operates to drive the sounding body 9 to generate sound. Next, when the operation button 6 is pressed, the mode switching circuit 7 switches the video tape recorder 5 to the pause mode, but at this time the sounding body 9 does not operate at all.

Therefore, when switching the video tape recorder 5 to the recording mode, a sound is emitted, but when switching to the pause mode, no sound is emitted, so when the operator presses the operation S opening 6, the video tape recorder 5 is switched to either mode. It is easy to identify whether it has changed. Of course, when switching to the recording mode, there may be no sound, and when switching to the pause mode, the sounding element 9 may be driven to emit sound.

FIG. 2 is a block diagram illustrating the operation of another embodiment of the present invention. When the operation button 6 is pressed, the mode switching circuit 7 switches the video tape recorder 5 to the recording mode, and the first sounding circuit 10 operates to drive the first sounding body 11 to generate sound. Next, when the operation button 6 is pressed, the mode switching circuit 7 switches the video tape recorder 5 to the pause mode, and the second sounding circuit 12 operates to drive the second sounding body 13 to generate sound. By making the sounding frequency 2, sounding volume, or sounding color of the first sounding body 11 and the second sounding body different, it is possible for the operator to know when the video tape recorder 5 when the operation button 6 is pressed, as in the previous embodiment. It is easy to identify whether the mode is switched to

Of course, even if the first sounding circuit and the second sounding circuit are integrated into one circuit and the sounding body is also one, the sounding frequency, the sounding volume, or the sounding color can be easily changed depending on the operation mode.

Although the above description has been made for a video camera incorporating a video tape recorder, it is obvious that the present invention is also applicable to a video camera connected to a video tape recorder by a cord.

Effects of the Invention As described above, the present invention has an operation button that repeatedly changes the operation mode of the video tape recorder between a recording mode and a pause mode by repeatedly pressing the operation button, and the pressing operation of the operation button changes the recording mode. By providing a sounding means that can audibly identify whether the operation button corresponds to the recording mode or the pause mode, it is easy to determine whether the video tape recorder has switched to either the recording mode or the pause mode when the operation button is pressed. Since it can be identified, you can operate it with confidence.

Furthermore, it is possible to prevent an accident in which the user does not realize that he or she has inadvertently pressed an operation button when carrying a video camera and takes unnecessary pictures.
