Abstract

PURPOSE:To simplify the operation with reduction in the key operation frequency at the reservation, by providing a reservation memory means with a control means for transferring and memorizing the operation time zone to enabling a timer reservation simply by a key operation for setting days of week and channels. CONSTITUTION:This timer reservation circuit selects the area for memorization of time zones in a memory 1 by operating a program number setting key 2 and transfers and memorizes the time zones previously memorized in a operation time zone memory to memory parts 9 and 13 of the memory 1, for instance, by operating a key 28. Normally, the contents of an operation time zone memory 29 are transferred to memory parts 9, 10, 11 and 12 and 13, 14, 15 and 16 of the memory 1. Thus, all reserving operations can be done simply by a day of week setting key 5 and a channel setting key 21 thereby enabling the operation simply and in a short time with the reduction in the key operation frequency at the reservation.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a timer reservation circuit installed in a video tape recorder or the like.

[Technical backbone of the invention] In general, recording and reproducing equipment such as video tape recorders, etc.
A timer reservation circuit is provided which can set and store a desired time in advance and place the device in a playback or recording mode at the stored time. FIG. 2 is a block diagram showing an example of a conventional timer reservation circuit of this type, which is of a type that can reserve four programs. A memory 1 for storing time and channels is provided with an area capable of storing four programs.

In addition, each area has an operation start time storage unit 9.1Q, 1112.
, operation end time storage sections 13, 14, 15, 16, and broadcast channel storage sections 17, 18, 19, 20. By inputting from program number setting key 2,
The memory selection circuit 3 selects a storage area of the memory 1 for reserving these times. Here, for example, the storage unit 9.13.
Assume that a storage area having 17 is selected. When the above operation is completed, the mode selection circuit 4 puts the circuit into the operation start time setting mode. In this mode, when a desired time is input to the time creation circuit 8 by operating the day of the week setting key 5, hour digit setting key 6, and minute digit setting key 7, the time creation circuit 8 will play or record based on the input signal. An operation start time for starting the cheap mode is created and stored in the memory section 9 of the memorandum. Next, the mode selection circuit 4 puts the circuit into the end time setting mode. In this mode, when the operation end time to end recording or playback is input to the time creation circuit 8 by operating the date adjustment key 6, the hour digit setting key 6, and the minute digit row 7-7,
The time creation circuit 8 creates an operation end time from the input data and stores it in the storage section 13 of the memory 1. Next, the mode selection circuit 4 puts the circuit into channel setting mode. In this mode, when a desired recording broadcast channel number is input into the memory 1 by operating the channel eco setting key 21, it is stored in the memory 8517.

On the other hand, the reference signal from the reference clock generation circuit 22 is supplied to the clock circuit 23, where the current time is generated. The created current time is supplied to the comparison circuit 24. This comparison circuit 24 reads out the stored contents of the memory 1 at an appropriate timing, compares the current time with the stored contents, and if they match, sends a control signal to the control circuit 25 to cause the device to perform a predetermined operation (recording, recording, etc.). playback, etc.).

[Problems with forward leaning technology] In the conventional timer reservation circuit as described above, each time a reservation is made,
It is necessary to set the operation start time, end time, and channel, and there is a drawback that the number of key operations required at the time of reservation is extremely large. ``But if you look at the recent trends in TV programs, for example, [a two-hour drama]
In many cases, the time slot is fixed, such as 1:00 to 22:55, and only the day of the week and broadcast channel are different. Even if it is possible to make a reservation in such a case, in the conventional timer reservation circuit, the number of times set by key operations at the time of reservation is the same, and there is no change in the fact that the reservation operation is frequent. .

[Object of the Invention 1] In view of the above-mentioned drawbacks, an object of the present invention is to provide a timer reservation circuit that can simplify the operation by reducing the number of key operations at the time of reservation.

[Summary of the Invention] The present invention provides a circuit for setting the normal operation start time and end time, and a memory setting means for separately storing a frequently used operation time period. The above objective is achieved by providing @ control means for transferring and storing the operating time period in the storage means for reservation when making a reservation for use, and by configuring the timer reservation to be made only by key operations for setting the day of the week and channel. It is something to do.

[Embodiment 1 of the Invention] Hereinafter, an embodiment of the invention will be described with reference to the drawings, in which the same parts as in the conventional example are denoted by the same reference numerals. FIG. 1 is a block diagram showing an embodiment of the timer reservation circuit of the present invention. The memory 1 has four storage areas (or four independent memory areas) so that four program reservations can be made, and each area has an operation start time storage section 9. 1o, 11.12
, operation end time storage section 13.14.15.16 and broadcast channel storage section 17.18.19.20SH are blanked. The memory selection circuit 3 has the function of selecting any one of the four storage areas of the memory 1 using the program number setting key 2. The day of the week setting key 5, the hour digit setting key 6, and the minute digit setting key 7 are keys for inputting 7 hours and 9 minutes of the day of the week.The data input from these keys is converted into a time code by the time creation circuit 8. Stored in memory 1. Channel setting key 21. is used to set a desired broadcast channel, and the signal is directly stored in the memory 1. The mode selection circuit 4 has a function of specifying the storage section of the memory 1 when reserving operation start and end times and channels in the memory 1. The operation start time is stored in any one of the operation start time storage units indicated by .12, and in the operation end time start mode, 13.1 of memory 1 is stored.
4. Store the operation end start time in the operation end time storage section indicated by 15°16, and enter the specified broadcasting channel number in the channel storage section indicated at 17.18 and 19.20 of number memory 1 in the channel setting mode. Make me remember. The reference clock generation circuit 22 generates a reference clock based on a commercial power supply or a crystal excavator. clock circuit 2
3 generates the current time from the reference clock of the reference clock generation circuit 22. Comparison circuit 24 compares the current time with the contents of memory 1, and if they match, generates a control signal to cause control circuit 25 to perform a predetermined operation. The control circuit 25 is a circuit that controls a video tape recorder or the like in which this timer reservation circuit is mounted, using a control signal from the comparison circuit 24, and controls operations such as starting and stopping recording. Operating time zone creation circuit 2
7 uses the key 26 to set the hour digit setting key 6 and the minute digit setting key 7.
This is a circuit that inputs data from and creates an operating time period.

The operating time slot memory 29 stores the operating time slot created by the operating time slot creation circuit, and outputs the stored operating time slot to the memory 1 by operating the key 28.

Next, the operation of this embodiment will be explained. First, in the normal reservation setting operation, the memory selection circuit 3 selects an arbitrary program storage area of the memory 1, and then the mode selection circuit 41. : For each mode set in Start time, operation end time,
This is done by memorizing the broadcast channel (number). Comparison circuit 24 compares the current time from clock circuit 23 and the contents of memory 1 at regular cycles, and when they match, sends a control signal to control circuit 25 to perform a predetermined operation.

Incidentally, in this example, frequently used recording operation time slots are created by the operation time slot generation circuit 27, and the timer reservation operation when using this operation time slot can be simplified. This operation will be explained below. For example, 21:00 to 22:00, which is often seen in recent TV programs:
50 dramas or movies, operate the key 26 to activate the operating time zone creation circuit 27, and then operate the hour digit setting key 6 and minute digit setting key 7 to set the above 2.
A time slot from 1:00 to 22:50 is created by an operating time slot creation circuit 27, and this time slot is stored in an operating time slot memory 29. In this way, after operating the program number setting key 2 to select the area of the memory 1 in which the time zone is to be stored, the key 28 is operated to change the time zone stored in the operating time zone memory into the memory 1. For example, it is transferred to and stored in the storage units 9 and 13. That is, 21:H is stored in the operation start time storage section 9 of the memory 1, and 22:50 is stored in the operation end time storage section 13. However, the contents of the operating time period memory 29 are always transferred to the storage section 9.1 of the memory 1.
This is now done for 0.11.12 and 13.14.15.16. Therefore, all reservation operations can be performed by simply operating the day of the week setting key 5 and channel setting key 21 and setting only the day of the week and the dial in the memory 1 using normal operations.

It goes without saying that the contents of the operating time period memory 29 can be changed freely.

According to this embodiment, once frequently used operating time slots are stored in the operating time slot memory 29, when making a timer reservation,
Key 28. @Date setting key 5 and channel setting key 21
All the reservation operations can be performed by simply operating the , and the number of key operations at the time of reservation can be reduced, making it possible to perform the operations easily and in a short time.

Although the above embodiment describes the case where there is only one operating time zone memory, it is possible to have multiple similar memories and store multiple operating time zones, so that an arbitrary operating time zone can be stored in memory 1. The same effect can be obtained even if the configuration is such that the operation is memorized in Step 2.

[Effects of the Invention] As described above, according to the timer reservation circuit of the present invention, a frequently used time slot is separately set and stored, and when a reservation is made to use this time slot, the time slot is stored. By configuring the reservation setting operation to be performed by transferring the reserved time slot to the reservation memory, there is an effect that the number of key operations at the time of reservation can be reduced and the operation can be simplified.
