Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a timer device suitable for use as a recording reservation timer of a video tape recorder (VTR), for example.

For example, when recording a television program on a VTR, the start time of the program is set in a recording reservation timer, so that recording automatically starts at that time. In that case, for example, a switch as shown in FIG. 1 is used to set the time.

In the figure, the "Reservation" button (1), "UP" button (2), [D
An OWNJ button (3) and a [NEXTj button (4) are provided.

To set the time, first operate the "reservation" button (1). This puts the device in mode for setting the day of the week and
Set the day of the week by operating the UPJ button (2) or l'-DOWNJ button (3). Next, operate the "NEXT" button (4). This puts the device into a mode for setting the hour of the recording start time, and the hour is set by operating button (2) or (3). Then operate button (4). This will put the device into the mode for setting the minute of the recording start time, and press the button (2).
) or (3) to set the minutes.

Then operate button (4). This will put the device into the mode for setting the recording end time, and press button (2) or (
3) Operate to set the time. Then operate button (4). This puts the device into a mode for setting the minutes of the recording end time, and the minutes are set by operating buttons +21-1: or (3). Then operate button (4). This puts the device in the mode of channel settings and presses button (2) or (
3) Operate to set the channel. Then, by operating a record button (not shown) at the stage where the above operations are completed, the apparatus enters a standby state for scheduled recording.

In this way, scheduled recording is set. However, in this case, the number of operations for buttons +2) and t3) is, in the worst case, 3 times to set the day of the week, 12 times to set the start time, 30 times to set the start minute, and 12 times to set the end time. It takes 30 times to set the end time, 6 times to set the channel, and 1 time to press button (1) and 5 times to press button (4), for a total of 99 times. Further, the l'-NEXT J button (4) etc. must be operated in a predetermined order, and the operating procedure is complicated. For this reason, it is difficult for elderly people and people who are not familiar with operating machines to use it, and there are problems such as easy operation errors.

In view of these points, the present invention is designed to allow the above-mentioned settings to be made with simple operations. That is, in the present invention, the numerical value corresponding to the day of the week is multiplied by the first constant,
A value obtained by multiplying the start time by a second constant is added to this multiplied value, a numerical code is provided by adding the recording time to this added value, this numerical code is divided by the first constant, and the day of the week is determined from this quotient. At the same time, this remainder is divided by a second constant, the start time is detected from this quotient, and the recording time is detected from this remainder. An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 2, the figure is a broadcast program list of television etc.
For example, it is divided vertically by broadcasting station (channel) and horizontally by each time. In each divided column, information such as the start time and title of each program (5)
is written, and a program code (6) consisting of, for example, a 7-digit numerical value is also written together with this description.

Here, the program code is formed as follows.

For example, Sunday is "0", Monday is "1", Saturday is "6", and each day of the week corresponds to a numerical value, and this number corresponds to the first
Multiply by a constant. Also, starting from 0:00 a.m., the value of the start time i expressed in minutes is multiplied by a constant of 8g2.

Furthermore, the recording time is expressed in minutes.

Then, the above-mentioned two multiplication values and the numerical value representing the recording time in minutes are summed to form a program code.

Further, FIG. 3 shows an example of the circuit configuration. In the figure, for example, the program code of a desired program is input from the above-mentioned program list using the 10 keyboard (1G). This input code is stored in the memory Uυ. Also, the desired program code is input using the channel selection device A channel is selected, and this channel number is stored in the memory (II).This sets the scheduled recording.

The program code from this memory circle is supplied to the divider circuit α3 and divided by the first constant from the numerical value setting circuit O.

This divided quotient is supplied to the comparator circuit (f5) through the day of the week detection circuit a9.The remainder from the division circuit 03 is supplied to the division circuit (17), and the second constant from the numerical value setting circuit divided. This divided quotient is supplied to the division circuit α9, and "60" is output from the numerical value setting circuit (20).
divided by This quotient and remainder are supplied to the hour and minute inputs of the start time of the comparator circuit (16).

Furthermore, the remainder from the division circuit (17) is supplied to the division circuit ■υ, where it is divided by "60" from the numerical value setting circuit port.

This quotient and remainder are supplied to the adder circuit -, and the divider circuit σl
The time is added to the hours and minutes from. This added value is supplied to the hour and minute inputs of the end time of the comparator circuit TIE.

Further, the time signal from the clock device (to) is supplied to the decoder (c) to form numerical values for the current day of the week, hour, and minute, and these numerical values are supplied to the comparison circuit (I61).

In this comparison circuit uQ, first, the detection circuit a9,
The day of the week and the hour and minute of the start time from the division circuit Q7) are compared with the day of the week, hour, and minute from the decoder (to), and when they match, the VTR is driven and recording starts. In other words, the coincidence output of the comparison circuit u61 is supplied to the power supply circuit (G) to turn on the power, and this power is supplied to the system control circuit (2η, tuner (2g+, recording/playback section C)!It, etc.) The output is supplied to the control circuit (5) to form a control signal for the recording mode, this control signal is supplied to the recording/playback unit, and the coincidence output is supplied to the tuner (to) to determine the channel number from the memory aυ. Reception is performed according to the received signal, and this received signal is supplied to the recording/playback section (21). Recording is thereby performed.

Furthermore, during the driving period, the comparator circuit tte outputs the end time hour and minute from the adder circuit (c) and the decoder (c).
The hours and minutes from 29 are compared, and when they match, the VTR is stopped and recording is terminated.

This is how scheduled recording is performed, but according to the present invention, the day of the week and start and end times can be set simply by inputting, for example, a 7-digit number using the 10 keyboard, making the operation extremely easy and free from errors. hard.

Note that the 7-digit number is the same as a telephone number in a large city, and is an appropriate number of digits for ordinary people to operate.

Therefore, the display may be divided into three and four digits as shown in FIG.

It is also possible to record a plurality of programs by storing a plurality of program codes and channel numbers in a memory circle and sequentially reading them out.

Further, the calculations in the divider circuit 031 to the adder circuit (c) and the comparison process in the comparator circuit 031 can also be executed by a so-called microcomputer.

It is also possible to write the number code in the form of a so-called barcode, and to input it using a pen-shaped barcode reader instead of the 10-key keyboard.

Further, the above-mentioned first and second constants are selected, for example, as follows. That is, if the number code is 7 digits, the maximum number r 9999999 j is divided by the number of days of the week "7", 9999999 ÷ 7 = 1428571, which is 1. Here, the first constant only needs to be smaller than this value, so for example, it is set to "1428570 J."

Then convert this first constant to the number of minutes in a day r 24 x 60
Dividing by j yields 1428570÷(24X60)=992, and the second constant is, for example, 992 J.

For example, Thursday 12:50-15:30
The code up to the minute is 4 X 142ss-7o + (12X 60 +
50) X 992+ (2X 60 + 40)
= 6478280.

Note that this program code may also include a channel X number. However, if this is done, the same program may be broadcast on a plurality of channels on the other side, which may cause inconvenience.

Further, the present invention can be applied to a tape recorder with a radio, etc.
