When the caller (caller) stands in front of the camera, it involves an answering device that can record the image and voice of the other party on a separate video tape.

Conventional Technology and Problems Conventionally, there is usually a person in charge of responding to visitors to each booth at an exhibition hall or the like. However, there is not always someone in charge, and they may be absent from their seats at times. In such cases, if the person in charge responds to the visitor with the video and audio of the person in charge, the visitor will be satisfied with this and will be able to speak his or her business message to the TV camera. This allows for smooth communication between both parties.

This application has been filed to achieve such an objective.

The first purpose of this application is to automatically play back the video and audio of the visitor from a cathode ray tube or television set when a visitor comes to a booth at an exhibition hall, etc., even if the visitor is not present, and to respond to the visitor. After inviting the visitor to sit in front of the TV camera, the message and video spoken by the visitor are recorded on another video tape recorder, and once the visitor stands up, the cycle ends and the next visitor is seated. The goal is to make it possible to perform actions that would prepare one.

A second object of the present invention is to make it possible to sequentially and automatically switch between two video monitors using the RF switch, so that only one monitor cathode ray tube or television set is required.

A third object of the present invention is to enable the video tape recorder to continue recording the external passageway, entrance to the booth, etc. after the visitor gets up and leaves the booth. The purpose is to enable the operation to continue in this state until the arrival of the condition.

Means for Solving the Problems The present invention provides a first system that is turned on by detecting the arrival of a visitor or by the call operation of the visitor, and turned off by detecting the departure of the visitor or by canceling the call operation.

By providing a video automatic response recording device, the above-mentioned problems were solved.

Function: When a visitor enters a place where the video automatic reception recording device is installed, for example, a booth at an exhibition hall, the first switch is activated by detecting the visitor's entry or by the visitor's calling operation. The means is turned on. When the first switch means is turned on, the first video tape recorder starts driving, and the RF switch is switched to the first video tape recorder side, and the reproduction display means is switched to the first video tape recorder. The information recorded on the set endless video tape is played back and displayed. When the end signal recorded at the end of the reception message on the video endless tape is played back, the second video tape recorder drive means is activated, and the RF switch is switched to the second video tape recorder. Switch to the recorder side, and
The second video tape recorder is driven to record and record the images and sounds taken by the video camera, and at the same time, are reproduced and displayed by the reproduction display means.

When the visitor leaves the booth, when the first switch means is turned off due to detection of the visitor's departure or release of the visitor's calling operation, the second switch means is turned off.
The second video tape recorder drive means stops operating, and the second video tape recorder stops recording images and sounds from the video camera.

Furthermore, if the manual switch disposed in parallel with the second video tape recorder driving means is turned on, the second video tape recorder will continue to operate even if the visitor leaves the booth. It records images and sounds from the video camera and acts as a surveillance device.

Example Hereinafter, the structure and operation of the present application will be explained.

In the figure, 1 is a video camera, which usually has a built-in microphone MIC-1. 2 converts the television camera into a video tape recorder (hereinafter referred to as VTR)
Recently, this adapter has been integrated with the camera, allowing the output line from the camera to be directly connected to the audio and video input terminals of the VTR. Some are. 3 is a VTR for reception
-1, and 4 is an R/F switch for connecting the output of VTR-1 to the television set.
Reference numeral 5 denotes an ordinary television set as a reproduction display means for displaying images. 6 is a VTR-2 for recording video and audio of the caller.
The R/F switch 4 is operated by the plunger coils SD-1 and SD-2 shown in the figure and the built-in spring action to operate the VTR-2, which will be described later.
is switched to the side, and when the SD-1 is energized,
The structure is such that an automatic switching operation can be performed such that the output is switched to the VTR-1 side and the output of the VTR-1 is broadcast on the television. Next, the symbols from SW-1 to SW-5 are switches;
SW-1 outputs video and audio from the video camera.
This is a switch for allocating input to VTR-1 and VTR-2, and is switched to VTR-2 after the response message has been recorded on VTR-1. The switch SW-2 is composed of interlocking switches SW2-1 and SW2-2, and constitutes a first switch means. The switch SW-2 operates in a flip-flop manner so that it is turned on when a visitor or caller enters the booth or calls the device, and turned off when the caller leaves the booth or stops calling. When the switch SW2-1 is turned on by the switching means configured as above, the VTR-1 is driven. Switch SW2
-2 is a switch interlocked with switch SW2-1, and is used to reset relay Y, which will be described later. Next, switch SW-3 microphones the signal sound generated when the response tape of VTR-1 ends.
The figure is representative of an audio switch that is picked up by MIC-2, activates relay Y, and turns on its contact. Switch SW4-1 is a plunger coil that is a means of switching the R/F switch to the first video tape recorder side.
It operates SD-1, and the above switch SW-
2, it will turn on when a visitor enters the booth or there is a call to this device, and the VTR will turn on.
This is for guiding the output of the tape No.-1 to the television set via the R/F switch 4. In addition, switch SW4-2 is for plunger coil SD-2, and when the relay Y is activated, it turns on and turns off power to plunger coil SD-1, and energizes plunger coil SD-2 to R/F. switch 4
This is to switch the microphone to the VTR-2 side.
The MIC-2, the relay Y, the switch SW-3, the switch SW4-2, the plunger coil SD-2, etc. constitute a driving means for the VTR of the present invention. The switch SW-5 is a switch installed in the cushion of the visitor's chair 7, etc., and is turned on when hung on the chair and turned off when the visitor stands up.
It functions as explained below.

The above-mentioned parts are connected by lead wires l1 to l6, among which l1 is the lead wire between the TV camera and the adapter, and l2 is the common terminal of the adapter and VTR video and audio input terminal switch SW-1. The lead wire, l3-1, is the switch SW-
The lead wire between the VTR-1 side terminal of 1 and the video/audio input of VTR-1, l3-2 is the switch SW-1 above.
This is the lead wire between the VTR-2 side terminal of the VTR-2 and the video/audio input terminal of the VTR-2. Next, l4 is the VTR
This is a lead wire for guiding the VHF output of -1 to R/F switch 4, and the VTR-1 of R/F switch 4.
It is connected to the terminal on the 1 side, and l5 is connected to the VTR-2 terminal.
This is a lead wire for guiding the VHF output of the R.F. switch 4 to the R.F. switch 4, and 16 is a lead wire for connecting the neutral of the R.F. switch 4 to the television antenna terminal. These parts are combined to form the basic structure of the present application.

Next, to describe its usage and effects, first,
When the owner is away, stand in front of the VTR camera,
By setting switch SW-1 to the right side and operating VTR-1, you can display your own video and message.
Record on the tape of VTR-1. At this time, when the message ends, a beep tone, that is, a signal sound prompting the other party to record, is recorded, like an answering machine. The endless tape used in the present application has a conductor foil or an indicator at the end, and automatically stops when the indicator reaches the end after going around the tape. After recording on the VTR-1 in this manner, once it is in the playback state, check it, and then turn off the power switch SW-2 or an alternative operating switch. As mentioned above, this switch SW-2 is shown as a representative of a switching device that operates like a flip-flop so that it is automatically turned on when a visitor comes to the booth and turned off when he or she leaves the booth. However, its specific structure may be a switch that operates by sensing light rays or a switch that operates by sensing sound waves. Alternatively, a switch installed under the mat may be used, and a known switch may be used.

In this way, when a visitor arrives while on standby, the switch SW-2 is turned on and the VTR-1 starts operating in the playback mode, so the image of the person in charge who is absent is displayed on the TV set via l4 and l6. It was broadcast on TV, and a message was sent to the caller or visitor saying, ``Since I'm away at the moment, I'm going to record your request. Please sit down in front of the television camera.'' Say something like, "Please talk to me." It goes without saying that you may provide a brief explanation of the machinery being exhibited at this time. In any case, when the message ends, a beep tone is generated from the speaker of the television set 5, so this beep tone is picked up by the microphone MIC-2 and relay Y is operated to maintain the self-holding state. When the contact point of this relay Y is set as switch SW-3, the above relay works and VTR-2
Since power is applied to the VTR-2 and the VTR-2 is set in advance to be in a recording state, when the power is turned on, the VTR-2 is in a recording state and the tape is running. At the same time, switch SW4-2 is the other contact point of the relay Y, so when it is activated, switch SW4-1 is de-energized and plunger coil SD-2 is energized, as shown in the circuit diagram. The switch 4 is switched to the VTR-2 side, and the video and audio input from the camera 1 and the microphone MIC-1 are recorded on the VTR-2. Therefore,
Visitors can also sit on chairs in front of the TV camera and talk while looking at their own images. Furthermore, when the user sits on the chair, the switch SW-5 located under the cushion operates to turn on the light or perform other functions. Also, people who don't like having their own image taken may not have to take pictures, but in this case, a television camera can capture and record the outside scene. In addition, when a visitor stands in front of the camera, it is possible to place a clock in the position where the visitor behind them is sitting, so that the clock is also displayed on the camera at the same time. It will be extremely convenient later on if you can easily know what is going on. In such a situation, when a visitor leaves his or her seat, a spring attached to the chair or the like returns to its original position, turning off the light or the like. Thereafter, when the visitor leaves the booth, the switch SW-2 is turned off and the next visitor's call is automatically put on standby. To do this, the switch SW-2 and the switch SW4-1 interlocked with it are first turned off, that is, set to a reset state. However, since the VTR-2 is equipped with a tape that can record for quite a long time,
In some cases, it may be better to continuously photograph the situation in the aisle, including people trying to look into the booth from the aisle, and people trying to visit, and use it for monitoring purposes. It is preferable to leave only the effect as is. For this purpose, a manual switch that can be manually turned on may be provided in parallel with the switch SW-3. Then, when a new visitor arrives, the switch SW-1 will have already been switched to the VTR-2 side.
In addition, R/F switch 4 is a plunger coil.
If SD-2 is only turned off, it is connected to VTR-2, so when a visitor enters the booth, switch SW2-1 and switch SW4-1 are turned on, and plunger coil SD-1 is activated. , As mentioned above, the VTR-1 starts playing, the image of the person at the reception and the message are played back, and the tone at the end of the tape is detected, relay Y is activated, switch SW-3, switch SW4-2, and plunger coil are activated. Using the SD-2, switch the R/F switch 4 to the VTR-2 side, and use the camera 1 to record the visitor's video and audio.
You can record VTR-2.

Effects of the Invention As described above, the present invention can perform the function of automatically answering and recording video tape recorders while the person in question is absent. You can rest assured that you can rely on this device even when you are absent, and since the situation during your absence is clearly shown on the VTR-2, you can continue working in the booth without alerting people around you. can. In addition, for those who wish to leave their own image and message, after responding to the absent person, they can leave a message and image of themselves while looking at their own image, making it practical as an automatic video response recording device. The present invention is of great value, and such a device has never existed before, so the applicant claims a patent within the above scope.
