Description

[Detailed Description of the Invention] [Technical Field of the Invention] [Technical Background of the Invention] In information recording equipment, such as a VTR, there is a program reservation timer circuit that can automatically record a desired program when the user is away, such as when the user is away. is provided. This type of circuit has a clock circuit based on the commercial frequency, etc., and compares this with specified time data input from the operation keys and automatically
Performs TR on/off processing. To specify the recording time, use the operation keys for day of the week, hour, minute, channel, etc.
There are methods such as setting the start time and end time, or setting the start time and then setting the recording time length.

As an example, a case will be described in which a setting is made to "record the 6th channel from 20:00 to 20:55 on Friday" at the current time (16:03J on Sunday).

First, press the day of the week operation key five times to set Friday.

(Since it is currently Sunday, pressing it five times will set it to Friday.) Next, press the hour operation key four times to set 20:00. (Currently 16
Since it is a time table, you only need to press it four times. ) then press the minute operation key 5
Press 7 times to set 00 minutes. Similarly, end time 20:
55 and finally specify the sixth channel using the channel key, the reservation is completed.

[Problems with background technology]

FIG. 1 shows the transition of setting values using the operation keys.

FIG. 1(a) shows the transition status of the days of the week, and each time the operation key is pressed once, the day shifts and cycles. The same figure (b
) indicates the hour, (c) the minute, and (d) the channel. The operation key changes the specified content by one unit each time it is pressed, but the minute operation key changes the specified content from O to 59'! !
, you have to press it 59 times.

Therefore, in order to improve this kind of operability, it is possible to make the content change continuously by holding down the same key, but in order to prevent operational mistakes, it is necessary to reduce the speed of continuous change. You can't do it that fast. It is conceivable to use two operation keys to enable up and down operations, but this would increase the number of operation keys and would be unsophisticated in terms of ease of reservation, price, and layout and layout.

[Purpose of the invention]

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a time designation circuit that allows time setting operations to be performed extremely easily and quickly.

[Summary of the invention]

In this invention, the key manual processing circuit 11 is provided with a key 13B that can change time data in 1-minute increments and a key 14B that can change time data in 30-minute increments, so that the time setting operation can be performed easily and quickly. It was designed so that it could be obtained.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to the drawings. 1st
In the figure, 11 is a key manual processing circuit, and 14k is provided for the first to sixth keys 11. The first to fourth keys 11A to 14A are day of the week data memories 11B, respectively.

Time data memory 12B11 minute data memory 13B, 3
It corresponds to the 0 minute data memory 14F3.

Each time the first key 11 is pressed, day of the week data from the day of the week data memory JIB can be sent to the data generation circuit 23 via the dart 11C. The second key 12A also changes the time data to the r-t 12c each time it is pressed.
The data can be sent to the data generation circuit 23 via. Furthermore, the third. The fourth keys 1.9A and 14A can also send 1 minute data and 30 minute data to the data generation circuit 23 via darts 13C and 14C, respectively. Next, the fifth key 15 is used to stop the operation of the clock circuit 17,
This is for restarting. Also, the 6th
The key 16 is pressed when the reservation time setting is completed, and is only used to set the controller 3θ to a standby state.

First, we will explain the current time correction function. Current time [
8:10 (8:10 a.m.) on Monday.

The memory selection circuit 24 is constituted by a slide switch, for example, and can switch between displaying the current 59th time, displaying the start time, and displaying the end time. When the enable signal is output to the control line 24A, the first memory 19
You will have to choose. When the first memo 1-19 is selected, the output data of this memory 19 is manually input and displayed on the display 32. Also in this case, the first memory 1
9 is an output from the data generation circuit 23, the contents of which can be rewritten.

Now, if we look at the display 32 and set the current time, the first key 11k is operated and the day of the week data is inputted from the day of the week data memory 11B75), inputted to the data generation circuit 23, and stored in the first memory. Display unit 32 via 19
will be displayed.

While viewing this display, the user operates the first key 11k until "Monday" is displayed. Next, the second key 12k is operated. This provides a time correction. Knee "!j' is 1 which gives the 8 o'clock display, and the second key 12k is operated. Next, the third key 13k is operated. This allows the minute to be corrected. Operate the third key 13fi until 10 minutes is displayed.The above operation means that the current time has been set, and at the timing of 8:10, press the fifth key 15 again. For example, the output of the clock circuit 17 is input to the first memory 19. This causes the time to advance.The clock circuit 17 accurately generates time data using the output of the basic clock generation circuit 18. ing.

Next, when making a recording reservation, the case of setting the start time will be explained. The starting time is [Friday 20
:OOJ. The memory selection circuit 24 is connected to the control line 2
4B to select the second memory 20. At this time, the second memo l),? The contents of o are
This second memo IJ 2 is input to the display 32.
The contents of o can be rewritten. day of the week, time,
To specify the minute, use the 1st. Second. Third keys 11A, 12k.

1.9 Operation A is performed. With this operation, if "Friday, 20:20J" is displayed, the start time setting has been completed.

Next, a channel for recording is reserved. Channel selection data is stored in the memory 33 by operating a desired channel key on the keyboard.

Next, the end time is set. In this case, the memory selection circuit 24 is operated and an enable signal is output to its control line 24C.

As a result, the third memory 21 is selected, its contents are displayed on the display 32, and the contents cannot be replaced. This content rewriting process is performed in the first step above. This is done in the same way as in the case of the second memory 19.2θ. The end time is 21:35J on Friday.

Therefore, the second key 12k sets 21:00, and the third key 13k then sets 32 minutes.

In this case, that is, when setting minute data for 30 minutes or more, according to the present invention, the data can be corrected in units of 30 minutes by one key operation using the data in the 30 minute data memory 1)14B.

That is, pressing the fourth key 14k once will set the time to 30 minutes, and then pressing the third key 13k twice will set the time to 32 minutes. This allows setting operations to be performed quickly and in a short time.

As mentioned above, adjust the current time, set the recording start time,
When the recording channel setting and end time setting are completed, all outputs of the memory selection circuit 24 are turned off. At this time, only the current time data in the first memory 19 is displayed on the display 3.
2 is entered and displayed.

Next, when the sixth key 16 is pressed, its output is input to the controller 30 and becomes a recording reservation setting. The controller 30 determines this, outputs a high-level signal H8 to the output terminal 30k, and applies it to the second input terminal of the AND circuit 28.

This means that recording reservation has been made.

When the current time advances and the output data of the first memory 1) 19 matches the data of the second memory 20 (recording start time data), this is detected by the comparison circuit 25. The comparison circuit 25 outputs a match output of . As a result, the output of the AND circuit 28 goes to the NO level, the R-87 lip-flop circuit 29 is set, and its output Q is held at the /. The controller 30 determines that the free lag frog circuit 29 is at level 7, and sets vTRtTR to high mode.

Next, when the recording time advances and the output data of the first memory 19 matches the data (end time data) of the third memory 21, this is detected by the comparison circuit 26. The comparator circuit 26 outputs a high-level coincidence output, which is applied to the reset terminal of the R-S flip-flop circuit 29. As a result, this fritsunofrotsuzo circuit 29
The output Q becomes low level, and the controller 30 determines this and stops the recording operation of the VTR. Note that when the recording start time is detected by the comparator circuit 25, the channel selection data in the memory 33 is read out by a coincidence pulse and sent to the channel selection circuit.

The above function can be used by setting the time of the program to be recorded in advance, for example, when the user is absent.

Furthermore, the device of the present invention also has the following functions.

While you are currently recording a program, there are times when you have something urgent to do and want to be absent. In such a case, normally you would turn off the VTR and go out, or you would turn on the IT in recording mode. However, with the apparatus of the present invention, the end time can be easily set according to the remaining time of the program being recorded. For example, suppose you have 30 minutes left in the program you want to record, and you run an errand that requires you to go out. In this case, an enable signal is generated on the control line 24D of the memory selection circuit 24 to select the fourth memory 22. by this,
The fourth memory 22 becomes capable of writing set time data. Next, the fourth key 14A is operated, and data for each 30 minutes is input into the fourth memory 22. In this case, since the current time data is also added to the fourth memory 22, data obtained by advancing the current time by 30 minutes will be stored in the fourth memory 22.

〔Effect of the invention〕

As described above, according to the present invention, when specifying minutes, the set time data can be varied not only in units of one minute, but also in units of 30 minutes. Therefore, when setting the time between 30 minutes and 59 minutes old, the setting operation becomes simple and quick. Further, the means for deriving the output of the 30-minute data memory can be used extremely effectively for automatic recording, especially when you are in a hurry before going out, because you can set and reserve 30 minutes with a single touch.
