Other Embodiments H Effects of the Invention A Industrial Field of Application The present invention relates to a time display device, and is suitable for use in displaying the time on a monitor attached to a video tape recorder, for example.

B. Summary of the Invention The present invention allows a time display device to display the time only at the time desired by the user, thereby making it possible to display the time more effectively.

C. Prior Art Conventional consumer video tape recorders record multiple programs on a longitudinally extending videotape.
A cue signal is recorded at the beginning of each program. For example, when a user wants to play a desired program from a recorded tape, the user must first set the video tape recorder to search mode and use the video tape to cue. After fast-forwarding the signal to a position where it can be played back, the user first switches to playback mode and checks whether it is the program he or she wants to watch.

Problem to be Solved by the Invention In this type of video tape recorder, it is possible to display the time on the display screen of the monitor together with the program video by using a predetermined time display means to notify the viewer of the time. It is thought that usability can be further improved.

However, if the time is always displayed on the display screen, there is a problem in that the program video originally displayed on the display screen becomes difficult to see.

One possible method for solving this problem is for the user to turn the time display on and off himself so that the time is not normally displayed on the display screen.

However, according to such a method, the user cannot avoid the troublesome effort of switching the time display on and off while always being aware of the time, and there is a problem that the user cannot enjoy the program calmly.

The present invention has been made in consideration of the above points, and it is an object of the present invention to propose a time display device that can display the time on a display screen when necessary.

Means for Solving EtlAB In order to solve this problem, the present invention includes a clock means 45, a storage means 44 for storing a preset time, and a timer 45 for storing a preset time. Display means 41.42.24.4 for displaying the time is provided.

F effect The user stores a desired set time in the storage means 44 in advance,
By displaying this on the display means 41, 42, 24 and 4 when the set time coincides with the time on the clock means 45, the time can be displayed only at the time that the user wants to know.

In this way, it is possible to prevent an obtrusive time display from being displayed when the user does not need it.

5 L In 5P52 and 5P53, the user
Clicking on the ``Register'' item, ``Change'' item, or ``Inquiry'' item starts the process of executing this.

In order to process the clicked item, the CPU 8 is configured to display a calendar reservation table, a weekly reservation table, and a daily child table in accordance with the user's selection in steps 5P54, 5P55, and 5P56, respectively. The start time and/or end time of a reserved program is written on a calendar reservation table, weekly reservation table, or daily child table.

After completing this process, the CPU 8 executes the above-mentioned step 5P2.
In step 8, the processing program for the management database is terminated, and the process returns to the management database processing loop (FIG. 7) from step 5P29.

The above is performed in step S in the initial command standby state shown in FIG.
By clicking on the "Management Database" item on P6, you can record, change, and record the management data on videotape.
This is a confirmation process, but if the user clicks on other specified items, such as the "system settings" item, the "favorite settings" item, or the "first timer reservation" item in the initial command standby state, The CPU 8 executes processing for setting operating conditions for each part of the video tape recorder 1.

That is, in step SP61 of FIG.
When you click "System Settings," the display screen displays the "Current time" item, "Sleep timer" item, "Recording mode" item, "Noise cancellation" item, rBS Online j item, "Auto set" item, and "Tuner preset" item. ” item and “Line manpower” item are displayed, and these items can be set in step 5P62.5P63.5P64.5P6 respectively.
By clicking on 5.5P66.5P67.5P68 or 5P69, you can set the operating conditions for each part of the system, and when the setting process is finished, C
The PU8 ends the processing of the system setting processing loop and moves to the above-mentioned step 5PlO.

In contrast, when the CPU 8 clicks on the "favorite settings" item in step SP71, the display screen displays the "screen display" item, "management database j item,""userset" item, "character j item," and "timer reservation" item. ” item, “User Level” item, “Message j item” and “Voice” item are displayed on the display screen, and these items are selected in step 5P72.5P73.5P74.5P75
．． When 5P76, 5P77, SF38, or 5P79 is clicked, the CPU 8 executes the process for each item, and when the process is completed, the process moves to step 5PIO described above.

Furthermore, in the initial command standby state, when the user clicks on the "Timer reservation" item in step SP81, the CPU displays the "Register" item and the "Change" item on the display screen.
Display the item and "Inquiry" item, and the user can proceed to step 5P.
82. When you click each item on 5P83 or 5P84, "Calendar reservation table j item,""1 week reservation table" item, and "1day child table j item are displayed on the west side of the display. If the user specifies one, CP
U8 makes a calendar reservation table, a weekly reservation table, or 1 in steps 5P85, 5P86 or 5P87 respectively
By displaying the schedule table, the user can make a reservation for a program using the reservation table.

When the CPU 8 has thus completed the processing of the timer reservation processing loop, it moves to the above-mentioned step 5 PIO.
