Description

[Detailed Description of the Invention] The present invention relates to a timer scheduled recording device for a VTR or the like.

Conventional VTRs equipped with a timer recording function have a timer recording set switch (hereinafter referred to as the "set switch"), and when this set switch is turned on, the VTR enters timer recording standby mode and cannot accept any external operations. Furthermore, when the set switch was turned off, even when the time set by the timer arrived, timer recording was not performed. Therefore, after setting the timer,
If you turn off the set switch to operate the VTR, and then forget to turn the set switch on after operating the VTR, the timer recording will not occur even though you have set the timer.

An object of the present invention is to provide a timer-scheduled recording device that reduces the above-mentioned operational disadvantages.

The present invention achieves the above object by providing a means for warning at or slightly before the start time of timer scheduled recording in order to prevent erroneous operation of timer scheduled recording.

An embodiment of the present invention will be explained below with reference to the configuration and operation diagram. A common terminal of the set switch 1 is connected to ground through a resistor 2 and a resistor 3, and a connection point between the resistors 2 and 3 is connected to the base of a transistor 4. The collector of the transistor 4 is connected to a power source 5 via a resistor 6, and to the base of a transistor 7. The collector of the transistor 7 is connected to the timer-on terminal of the timer 14 via a resistor 8. A timer-on terminal 15 of the timer 14 is connected to ground via a resistor 9 and a resistor 10, and a connection point between the resistors 9 and 10 is connected to the base of a transistor 11. The emitters of transistors 4, 7, and 11 are all connected to ground. The collector of the transistor 11 is
It is connected to a power source 5 via a resistor 12 and a light emitting diode 13. The timer 14 is always fixed in timer recording mode. When set switch 1 is on, transistor 4 is on, transistor 7 is off, and timer on terminal 16 is turned on.
The output becomes open and the timer recording mode is entered. When set switch 1 is off, transistor 4 is off, transistor 7 is on, and the output of timer-on terminal 16 is shorted to ground, preventing the timer recording mode. When the timer-on terminal 16 is turned on, the transistor 11 is always turned on and the light emitting diode 13 emits light, indicating that the timer is on. Therefore, even if the set switch 1 is in the off state, when the time set by the timer arrives, the light emitting diode 13 lights up to notify that the time set by the timer has arrived, and operational errors can be greatly reduced. .

Furthermore, when setting the time using the timer 14, the timer 14 is configured to generate an output for a predetermined short period of time, such as several minutes, before the input set time, and the output causes the light emitting diode 13 to be output.
The actual output that starts the operation of the VTR can be configured such that the previous output is used as a trigger to count down the reference signal inside the timer, and the output is output after a predetermined short time. In this way, it is possible to warn the user that the timer is approaching the set time for a shorter period of time than the set time, for example, several times before.

According to the present invention, when the time set by the timer arrives, even if the set switch is turned off, the time set by the timer is reached.
This has the effect of greatly reducing operational errors such as not being able to record a program that the user had tried to record using a timer reservation, and greatly improving operability.
