Abstract

PURPOSE:To prevent misrecordings such as unrecording and incomplete recording, etc., by providing a detecting and warning means for detecting nonloading and imperfect loading of a microphone and also warning as well. CONSTITUTION:The device is provided with a microphone detecting circuit 102 for detecting nonconnection and imperfect connection of the microphone 2 by turning on/off a switch of a microphone jack 101, a warning output circuit 103 for generating an output required for warning by a detected signal of the microphone detecting circuit 102 and a light emitting diode 104 for emitting light by the output from the warning output circuit 103. Consequently, the state of unloading or imperfect loading of the microphone can exactly be recognized by the warning from the detecting and warning means X without monitoring a sound by a recorder at the time of starting the recording. By this method, misrecordings such as unrecording or incomplete recording, etc., at the time of recording are prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a recording device equipped with a detachable microphone.

(Prior Art) FIG. 3 is a perspective view of a camera-integrated video camera equipped with a detachable microphone (hereinafter referred to as microphone), which is a conventional example of a recording device.

In FIG. 3, 1 is a video camera body, 2 is a detachable microphone, 3 is an electronic viewfinder (EVF'), 4 is a camera holder, 5 is a recording button, and 6 is a headphone terminal. Recording is performed by pressing the record button 12 and driving the VTR built into the video camera body 1.

Since the audio being recorded is recorded through the microphone 2, the recorder can confirm that the audio is being recorded correctly by connecting headphones (not shown) to the headphone terminal 6 of the video camera and monitoring the recorded audio. was checking.

[Problem to be solved by the invention]

However, conventionally, checking the audio recording as described above is troublesome, and recorders often do not monitor the audio and do not use the microphone because they do not want to miss the recording timing or because they trust the recording device. There is a problem that recording may be performed without realizing that the device is not installed or that the device is not installed, and it is only during playback that the user realizes that no audio has been recorded.

This invention was made in order to solve the above-mentioned problems of the conventional method, and it is possible to notify the recorder that the microphone is not attached or incompletely attached without having to monitor the audio at the beginning of recording. The purpose is to provide a recording device that can accurately detect and warn.

(Means for Solving the Problems) For this reason, the recording device according to the present invention provides a detection and warning means for detecting and warning if the microphone is not attached or incompletely attached in the recording device in which the microphone is removably installed. By providing this, the above objective is achieved.

[Effect]

In the recording device according to the present invention configured as described above, when the recorder starts recording, the detection and warning means warns the user that the microphone is not attached or not attached. Recording errors such as complete recording are prevented.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings.

(Structure) FIG. 1 is a circuit block diagram of a main part of a recording apparatus according to an embodiment of the present invention.

In FIG. 1, parts that are the same as or corresponding to those of the conventional example are indicated by the same reference numerals.

In Figure 1g1, 7 is a microphone terminal, 10 is the main body of the recording device, 101 is a microphone jack with a switch for connecting microphone 2 (hereinafter referred to as microphone jack), and 102 is a microphone terminal that connects microphone 2 by turning on or off the switch of microphone jack 101.
103 is a warning output circuit that generates an output necessary for warning based on the detection signal of the microphone detection circuit 102, and 104 emits light by the output from the warning output circuit 103. A light emitting diode, 105 is a microphone amplifier. In the illustration, a microphone jack 101 and a microphone detection circuit 102 are shown.
A detection circuit A having a detection function is connected to a warning output circuit 10.
3 and the light emitting diode 104 respectively form a warning circuit B having a warning function, and the detection circuit A and the warning circuit B constitute a detection warning means X.

(motion) The operation will be explained based on the above configuration.

If the microphone terminal 7 is not connected or is incompletely connected to the microphone jack 101 of the recording device main body 10, the switch of the microphone jack 101 of the recording device main body 10 is turned on, the microphone detection circuit 102 operates, and a detection signal is sent to the warning output circuit 103. Output to. Upon receiving the detection signal, the warning output circuit 103 generates an output necessary for a warning, and this output causes the light emitting diode 104 to emit light to warn the recorder that the microphone 2 is not attached or is incompletely attached. Recording errors such as unrecorded or incomplete recording can be completely prevented.

Next, FIG. 2 shows the main circuit configuration of a recording apparatus according to another embodiment of the present invention.

In FIG. 2, reference numeral 8 indicates a switch suppression protrusion arranged in parallel with the microphone terminal 7 of the microphone 2a, 20 indicates the main body of the recording device, and 1
06 is a microphone jack, 107 is a switch that operates when the protrusion 8 is completely inserted into the recording device main body 20,
108 is a warning display circuit, 109 is an imaging device, and 110 is an adder.

The switch 107 and the microphone detection circuit 102 form a detection circuit A, the warning display circuit 108 and the adder 110 form a warning circuit B, and the detection circuit A and the warning circuit B form a detection warning means X. There is.

The operation will be explained based on the configuration shown below.

If the microphone terminal 7 is not connected to the microphone jack 106 or is incompletely connected, the switch 107 in the recording device main body 20 is turned off, and the microphone detection circuit 102
detects the off state and outputs a detection signal to the warning display circuit 108. The warning display circuit 10B that receives the detection signal outputs a desired display signal, and the adder 15 adds this output signal to the video signal from the imaging device 109 to visually display a warning on the video of the EVF 3. To enable a photographer to accurately confirm whether a microphone is not attached or not attached at the time of photography before starting photography.

In this case, the warning display is not limited to the EVF 3, and may be displayed on any monitor member.

In addition, as another embodiment, a sounding member such as a buzzer is used in place of the light emitting member such as the light emitting diode 104 of the above embodiment, so that by remote control operation etc.
Warnings can be easily confirmed even when recording operations are performed at a location away from the recording device. In this case, since the microphone is not connected, no harmful buzzer sound is recorded.Furthermore, a configuration may be adopted in which a warning is given using means such as voice, liquid crystal display, and vibration.

(Effects of the Invention) As explained above, according to the present invention, the warning means detects that the microphone is not attached or is incompletely attached, without the need for the recorder to monitor the audio at the start of recording. Since the information can be recognized accurately, recording errors such as non-recording or incomplete recording can be completely prevented.
