Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a program timer device for a video tape recorder or the like, and more particularly to a program timer device that stores a plurality of programs and can select and record a plurality of television programs.

Video tape recorders (hereinafter referred to as VTRs) are generally used to record television signals, and in particular are often used to record broadcasts while you are away using a timer. Conventionally, the timer used for recording when you are away can only be set for one time (ON time), and once the power is turned on and recording starts, the broadcast signal of the set channel is recorded until the tape ends. continues to be. Therefore 15
Even when recording a minute program, if a new 2-hour tape was used, 2 hours would be recorded, resulting in damage to the tape, wasted electricity, and damage to parts.

This idea was made in response to the above points, and it allows you to freely preset and record two or more desired programs, eliminates mistakes when using it, and ensures that programs are recorded while you are away. The purpose is to provide a program timer device that can.

An embodiment of this invention will be described in detail below with reference to the drawings.

In the figure, a indicates the time and day of the week display section, for example, a liquid crystal element is applied, and the time and day of the week are displayed in seven segments.
Minutes, AM, PM, and day of the week are displayed. B is a switch for changing the program writing/reading state, and is composed of a two-contact slide switch that changes the display on display section a between the normal time display (at this time, the readout state) and the programmed time display (at this time, the readout state). This is used to switch the write state). c is an information setting switch for setting the time, day of the week, and channel number, that is, time information and control information; when memory changeover switch b is switched to the program side;
When the clock is switched to the clock side and the time adjustment switch i is turned on, the hour, minute, and day of the week are changed using the information setting switch c.
When you press the time advance button, the time display on display section a advances by 1, and if you continue to press it, the time display advances by 1, for example.
After a second, the time display continues to advance at a speed of 2 to 4 seconds. If you press the reverse button, the time display will go back to the opposite direction. The minute display can also be changed in the same way. The display of the day of the week can be changed by pressing the day of the week button and moving the point below the day of the week display on the display section a. Changing the channel using the channel number setting button is performed only when changing the program, and the display light source (not shown) of the channel number display section f is switched and turned on, so that only the set channel number is displayed brightly. Normal channel switching is performed using the channel selection button e. d is a power switch, which is composed of three contacts and is used to turn the power on and off and switch the timer.
g is a switch that changes information, and by this, 4
Two programs can be set. Each program is configured so that it becomes one set when the power is turned on and off. h is a clear button for clearing the memory contents of the program. j is a memory circuit that stores time information and control information for channel switching and power ON/OFF, k is a clock circuit that outputs a time signal, and l is information from memory circuit j and a clock from clock circuit k. Upon receiving the signal, the display section a,
m is a channel selection voltage generation circuit that receives channel information from memory circuit j and generates a channel selection voltage corresponding to that channel; n is a time signal from a clock circuit and the time of the memory circuit. When the information is compared and matches, the VTR
o is an electronic tuning tuner that receives the channel selection voltage from the channel selection voltage generation circuit m and receives the broadcast signal of the channel.

To actually store a program, first switch the memory changeover switch b to the program side to put the memory circuit j in a writing state. At this time, the memory contents of memory circuit j are displayed on display sections a and f.
Next, turn on the information changeover switch g to program 1, and set the recording start time and channel number using the information setting switch c. Next, the information changeover switch g is turned off for program 1, and the recording end time is set using the information setting switch c. In this case, the channel number is program 1.
It needs to be the same as that of ON. From now on, do the same and complete the memory of all programs. Thereafter, the memory changeover switch b is switched to the clock side so that a normal clock display is performed.

To operate the timer, press the power switch d.
switch to the timer side. When performing a timer operation, it is preferable to be able to select a program. That is, inconveniences may occur if all four programs are always running. For example, if you only need one program, you need to set the other three programs at unrelated times, and if you forget to set the other programs,
4, and you may not be able to record as desired. Therefore, in this invention, the information changeover switch g is used as a two-circuit switch to also select a program. In other words, if you set program 1 (ON/OFF common), only program 1, if you set program 2, programs 1 and 2, program 3, programs 1, 2, and 3, and program 4, programs 1, 2, 3, and 4. are all selected. Conversely, when program 1 is selected, all programs 1 to 4 may be selected, and all programs after the selected number may be selected.

A timer operation is performed depending on the selected program.

Note that the channel number program must be the same for ON and OFF of the same program, so no matter which program is set, the channel number set later will automatically be the channel number of the other program. becomes.

Also, the program runs in the order of the program closest to the current time.

As described above, the program timer device of this invention allows a plurality of programs to be set and is effective. Furthermore, since the information changeover switch g is also used as a program selection switch, the operation is simple, no operational errors occur, and the number of parts can be reduced.
