Embodiments of the present invention will be described below with reference to the drawings. 1 to 5 show an embodiment of the present invention, and in this embodiment, a case where time data is input to a VTR in a production line of a VTR which is a video device is shown. The VTRs placed on the pallets are sequentially supplied to the data input process by the belt conveyor, and the time data and the like are input therein.

In FIG. 1, the automatic data input device 1 is used for V
A circuit block diagram for inputting data to TR2 is shown. In FIG. 1, the video output line of the VTR 2 is connected to the monitor 3 and each video input terminal of the automatic data input device 1.

The VTR 2 has various screen generators 4 built therein, and the various screen generators 4 are configured to selectively output video signals such as menu screens and various data input screens. As shown in FIG. 5, the menu screen displays a plurality of menu data and a cursor for selectively instructing each of the menu data. The background is blue and the menu characters and cursor are white (black in the drawing, but actually white). Is displayed. The various screen generators 4 control the screen displayed by the control signal of the system controller 5 and change the position of the cursor by the cursor movement pulse of the system controller 5.

The receiving section 6 receives a signal from the remote controller 15 described below and outputs this received signal to the system controller 5. The system controller 5 executes the flow shown in FIG. 2 on the basis of this received signal, and its detailed configuration will be described in the operation section.

The automatic data input device 1 has a white level detecting section 7 and a detecting section 8.
The video signal of the VTR 2 is guided to the detector 8. The white level detection unit 7 detects the white level section of the video signal and outputs the H level only to this section to the control unit 12. That is, the character position and the number of character strings on the screen are detected by detecting the white level.

The detection section 8 detects the video signal to obtain a detection output. Since the detection output has a value proportional to the magnitude of the white component, the level differs depending on whether or not there is a cursor in each character string, and this detection output is supplied to the gate circuit 9. The gate pulse of the control unit 12 is supplied to the gate circuit 9, and the detection output is passed to the comparison unit 10 only during this gate pulse section. The comparison unit 10 includes a reference voltage generation unit 1
The reference voltage of 1 is input, and the comparison unit 10 outputs the H signal to the control unit 12 when the detection output is larger than this reference voltage. The reference voltage generator 11 is configured so that the reference voltage can be changed by a control signal from the controller 12.

The timer 13 outputs time data to the control unit 12 in response to a request from the control unit 12. The memory 14 stores screen position data for all menu data of the menu screen and each reference voltage data without a cursor, and outputs each data to the control unit 12 in response to a request from the control unit 12.

The control unit 12 controls various circuits as described above to execute the flow shown in FIG. 3, and outputs a command signal to the remote controller 15. The contents of the flow of FIG. 3 will be described in the section of action.

The operation of the above configuration will be described below with reference to FIGS. The automatic data input device 1 is set to the clock set mode, and the reference voltage generator 11 is set to the reference voltage for clock setting. When the VTR 2 is supplied, the control unit 12 of the automatic data input device 1 outputs a menu mode signal. When this menu mode signal is transmitted to the VTR 2 via the remote controller 15, the system controller 5 outputs a control signal to the various screen generators 4 and the various screen generators 4 display the image signals of the menu screen shown in FIG. 4 (shown in (a)).

The white level detection unit 7 of the automatic data input device 1 outputs the output pulse shown in FIG. 4B, and the control unit 12 outputs the gate pulse corresponding to the fifth pulse corresponding to the character string of the clock set (see FIG. 4 (shown in (d)) is output to the gate circuit 9. Further, the detection unit 8 of the automatic data input device 1 outputs the detection output shown in FIG. 4C, and the gate circuit 9 outputs only the signal portion corresponding to the character string of the clock set to the comparison unit 10 ( It shows in (e) of FIG.

When the cursor is located at a position other than the clock setting position, the output of the comparison unit 10 is the L signal, so the control unit 1
2 outputs a cursor movement signal. When this cursor movement signal is transmitted to the VTR 2 via the remote controller 15, the system controller 5 outputs a cursor movement pulse to the various screen generators 4, and the cursor on the menu screen is displaced to the menu data position one level below. It Then, in the same manner as described above, the detection output at the clock position and the reference voltage are compared by the comparison unit 10, and if the output of the comparison unit 10 is the L signal, the cursor on the menu screen is further displaced to the menu data position one level below. Then, the above operation is repeated.

The cursor moves to the clock set position (E in FIG. 5).
Position), the detection output at the clock position becomes higher than the reference voltage (shown in (e) of FIG. 4).
Therefore, the comparison unit 10 outputs the H signal as shown in FIG. Then, the control unit 12 outputs the data input mode signal to the remote controller 15 and the data is transmitted to the VTR 2 via the remote controller 15. The system controller 5 outputs a control signal to the various screen generating section 4, and the various screen generating section 4 outputs a video signal of the data input screen.

Next, the control unit 12 of the automatic data input device 1
Outputs the time data of the timer 13 to the remote controller 15 and is transmitted to the VTR 2 via the remote controller 15. The system controller 5 outputs the time data to the various screen generating section 4 and is stored in the various screen generating section 4. That is, it is stored in the memory area of the clock set data input screen.

Although the clock set data is automatically input in this embodiment, other data can be automatically input in the same manner. Although the VTR 2 is taken as an example of the video equipment in the present embodiment, the present invention can be applied to all equipment handling video signals such as a television and a laser disk drive device.
