Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a timer reservation display device for displaying whether or not a timer operation reservation operation has been performed, and particularly to a timer reservation display device for a timer used in a recording device such as a tape recorder.

A recording device, such as a video tape recorder (hereinafter referred to as VTR)
When making a timer operation reservation using a timer device in order to cause a recording operation to occur at a predetermined time, various operations are required in addition to setting the timer device. In other words, a general timer device turns on (or turns off) a VTR, which is a controlled device, at a set time.
If the VTR is not in a recordable state at this time, normal recording operation will not be performed. To achieve this recordable state, the magnetic tape, which is the recording medium, must be
It is necessary that the VTR be mounted in a predetermined position, and that the mode selection button of the VTR be operated to record mode. For VTRs that can be connected to this timer and are equipped with a timer standby button that keeps the pinch roller away from the capstan shaft, it is necessary to set this timer standby button to prevent damage to the pinch roller. It is. However, the display device of a conventional timer device only displays whether or not the timer device itself is set, and the timer set display is performed even if the VTR, which is the controlled device, is not in a recordable state. .For this reason, even if there is a flaw in the reservation operation, such as forgetting to insert a magnetic tape or operating a button other than the recording mode selection button, it is often not noticed because the timer set is displayed. Recording failure will occur./In addition, if someone else uses the VTR temporarily after the timer reservation operation but before the timer recording operation, the VTR will fail after this temporary use.
The reservation holder may want to check whether the TR has been operated to be able to record again, but to do so, it is necessary to check whether all the operations necessary for the timer reservation described above have been performed. - It's a hassle.

The present invention has been made in view of the above circumstances, and provides a system that displays whether or not all operations necessary for timer reservation have been performed, thereby preventing failures in timer recording due to malfunctions or forgotten operations. The purpose is to provide a timer reservation display device.

Preferred embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an external perspective view of a timer built-in VTRI equipped with a timer reservation display device as an embodiment, and the power switch 2 has three stages of TIMER, ON, and OFF.

When the power switch 2 is switched to the TIMER position, the power is automatically turned on at the time set by the built-in timer. The time display section 3 normally displays the current time, and when setting the timer time, the set time is displayed. In addition, ``instead of this digital timer'' and ``various types of timers such as mechanical timers with rotating hands may be built in.Next, ``In order to perform complete recording at the timer setting time,'' the above-mentioned timer In addition to the time setting operation, it is at least necessary that the video cassette tape 5 be loaded into the cassette holder 4 of the VTR box and that the record button 6 be pressed.

In this embodiment, only when all of these conditions are satisfied, the indicator light turns on to indicate that the timer reservation has been completed.In other words, each of the above conditions for timer reservation If any one of the conditions is not satisfied, the indicator lamp 7 will not light up, so it can be confirmed at a glance that the timer reservation operation is incomplete. Although various specific circuit configurations of such a timer reservation display device are given, for example, as shown in FIG. Switch Hiro Kame, 12, 13
may be connected in series between the indicator lamp 7 and the power supply terminal 8.

Here, the switch 11 is set when the power switch 2 is set to TIME.
Switch 12 is the switch that turns on when the switch is switched to the R position. Switch 12 is the switch that turns on when it detects that the video cassette tape is inserted into the cassette holder 4. Switch 13
is turned on when the record button 6 is pressed. In this circuit, all switches a turtle, 12, 1
The display lamp 7 lights up only when the power switch 3 turns ○N.The circuit in FIG. 2 may also be configured as shown in FIG. T
The timer operation mode detection layer 14 outputs the signal "rl" when the video cassette tape 5 is in the IMER position, and outputs the signal "rl" when it detects that the video cassette tape 5 is installed in the cassette holder 4.
It has a cassette detection device 5 that outputs a signal "1", and a recording mode detection device 16 that outputs a signal "rl" when the record button 6 is pressed. The output of 6 is sent to the AND circuit 17,
The output of the AND circuit 17 drives the display lamp 7 to turn on. In this case, the indicator lamp 7 lights up only when the outputs of the above-mentioned devices 4, wings 6, 16 are all 1.
As is clear from the above description, the timer reservation display layer according to the present invention is configured such that a recording medium, such as a video cassette tape 5, is placed in a predetermined position of a recording device such as a VTR.
be installed in the cassette holder 4 of I.

■ Recording device is in timer operation mode! This is what happens.

For example, the power switch 2 on the VTR wing is switched to the TIMER position. Glue The recording device is in recording operation mode.

For example, when at least three conditions such as ``the recording button 6 of the VTRI is pressed'' are satisfied, a timer reservation completion indication is displayed, for example, the display lamp 7 is turned on. Therefore, by checking the display indicating completion of timer reservation, all conditions necessary for timer reservation can be checked at once, which is convenient.

In addition, if the above display is not displayed when the timer reservation operation is completed, it is easy to see that there is a malfunction or forgotten operation, so it is possible to prevent timer recording failures due to such malfunctions or forgotten operations. Furthermore, even if the recording bag hawk is used by another person after the timer reservation operation but before the timer recording operation starts, it can be easily determined whether the timer reservation operation has been performed again after use by the above-mentioned timer reservation completion display. This saves the trouble of checking each individual operation.The present invention is not limited to the above-mentioned embodiments.
In addition to the R (video tape recorder), a general tape recorder for audio recording, a magnetic disk recorder, or a recording device for optical recording can be used.

Moreover, not only a recording device with a built-in timer but also a recording device with an external timer connection may be used. In addition to the visual display using the indicator lamp 7, light emitting diode, etc., it is also possible to use an auditory display such as a buzzer or a signal sound when the timer reservation operation is completed. Furthermore, as conditions for completing the timer reservation, ``In addition to the above three conditions, conditions such as the timer standby button being set and the magnetic tape being wound on the supply reel side must be added.'' , the timer reservation completion may be displayed only when all of these additional conditions are satisfied.
