Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Field of Industrial Application) The present invention relates to a video tape recorder with improved one-touch timer recording (hereinafter abbreviated as OTR).

(Prior Art) Usually, in this type of video tape recorder, after a recording operation is performed by operating a recording key (also referred to as a REC key), recording is performed up to the end of the tape in the mounted cassette tape. Alternatively, the recording operation ends only when the stop key or the power key is operated in the middle.

Therefore, when the operator is absent after the start of recording, the recording is executed until the end of the tape.

Therefore, an OTR function that allows you to input the end time with one touch when recording starts is now provided.

This OTR setting is REC for normal recording mode setting.
An OTR key was provided separately from the key, and this key was used to start recording and set the end time.

(Problems to be solved by the invention) In the above-mentioned conventional OTR input method, since the OTR key is arranged separately from the REC key for normal recording, the number of keys has recently been diversified due to the diversification of functions of the VCR. In the actual situation where the number of keys is increasing, there is a problem that the layout of the front panel is hindered and the number of keys is increased so much that the operability is rather deteriorated.

Therefore, an object of the present invention is to solve the above-mentioned conventional problems and not to arrange a dedicated OTR key for realizing the same function as OTR, but also to use it as a REC key for normal recording. Therefore, it is an object of the present invention to provide a video tape recorder that reduces the number of keys to facilitate layout and does not impair operability.

[Structure of the Invention] (Means for Solving Problems) The present invention provides a video tape recorder capable of setting an OTR mode for setting a recording end time with one touch, in addition to a normal recording mode by a REC key. A recording control unit for controlling the start of the normal recording mode and the OTR mode based on the operation of the REC key, and for controlling the end of the OTR mode, and for the OTR mode based on a command from the recording control unit. A display unit for displaying information is provided, and the recording control unit controls the start of recording in the normal recording mode by the first operation of the REC key, and the second operation of the REC key. By the O
Means for instructing the display of the TR confirmation state, means for judging whether or not the REC key has been operated a third time before the elapse of a predetermined time from the second operation of the REC key, and before the elapse of the predetermined time. If the REC key is not operated for the third time, the means for canceling the display of the OTR confirmation state on the display unit and resetting to the normal recording mode, and the means for resetting the normal recording mode 3 When the REC key is operated for the third time, the OTR time setting mode is set, and the recording end time of the OTR mode is set according to the time when the REC key and the key-on operation is continued for the third time. Means for instructing display on the display unit, means for controlling start of recording in the OTR mode based on the recording end time in the OTR mode determined by the third key-off operation of the REC key, and the recording end time When it arrives, the OTR mode And a means for controlling the recording of the video to be stopped.

(Operation) In the present invention, the key used for setting the OTR mode is also used as the REC key for setting the normal recording mode. And
The recording control unit that inputs the key-in information of this REC key,
When the REC key is operated for the first time, recording is started as the normal recording mode, and when the REC key is operated again thereafter, the OTR mode is set.

Here, the conventional OTR key does not change to set the recording start by the operation, and only the selection of the recording end time is added. Therefore, in the present invention, the normal recording mode and the OTR are set for the recording start. When the OTR mode in which it is necessary to set the recording end time by starting the first operation of the REC key without distinguishing between modes, it is possible by operating the same key again.

Further, according to the present invention, the following actions and effects can be expected.

(B) After the normal recording mode is started by the first operation of the REC key, and when the same REC key is operated for the second time with the intention of setting the OTR mode, the OTR confirmation state is set. You can check the transition on the display.

(B) Even if you accidentally operate the same REC key again (second time) while intending to continue the normal recording mode, unless you consciously operate the third REC key, It can be automatically reset to the normal recording mode as intended at random.

(C) The OTR mode time setting mode must be set within the specified time with a clear intention to set the OTR mode end time.
It is set only when the second operation is performed. Moreover, in the third REC key operation, the length of the recording end time is determined according to the time during which the key-on operation is continued. In this way, by clarifying the meaning of the keys different from the second and third operations of the same REC key, depending on the key operation method (simply pressing or continuing), the operator can set the settings as intended. It becomes possible to encourage.

(D) In order to enhance the function of (c), if the third REC key on operation is simply an operation that does not intend to set the recording end time, simply press the standby state. Then, the normal recording mode can be set again.

(E) The recording end time of the OTR mode is decided according to the time that the key-on operation of the third REC key is continued.
In addition, the OTR mode is controlled to start based on the key-off operation, and two functions can be realized by the third operation of the REC key once.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram for executing a recording operation of a video tape recorder which is an embodiment of the present invention, and FIG. 2 is a front view of a front panel.

In FIG. 2, the OTR key is not provided on the front panel of the apparatus of this embodiment, and only the REC key 1 is arranged. In addition, 2 is a stop key, 3 is a power key, and 4 is a display for displaying various patterns, modes, time and the like. In addition, various keys and indicators for executing the functions of the VCR are arranged.

Based on the operation of the REC key 1, the recording control unit 10 that controls the recording operation drives and controls the recording drive unit 20 to start recording, and in the OTR mode, drives the timer 30 and counts down to The drive unit 20 is driven to stop.

Next, the operation of the apparatus having the above configuration will be described based on the flowchart of FIG.

First, in the power-on state after operating the power key 3 (step 1), when there is the first key-in of the REC key 1 (step 2), the recording control unit 10 for inputting this key-in information immediately records. The drive unit 20 is drive-controlled to start the recording operation (step 3).

Thereafter, the recording control unit 10 determines whether or not there is a second key-in by the REC key 1 (step 4). If this key-in is not present, normal recording will be continued, but if this key-in is present, the OTR confirmation state will be entered (step 5). When the OTR confirmation state is reached, the display 4 displays OTR as shown in FIG. 4 (a). In this case, since the recording end time has not been set yet, the time display column is blank. Has become.

After the second key-in, it is judged whether or not there is a third key-in by the REC key 1 within a predetermined time, for example, within 10 seconds (step 6), and if not, the confirmation state of the OTR mode is released. Then, the process returns to step 3 which is the normal recording mode (step 7).

If the third key-in is within the predetermined time, the recording time setting mode is set by this third key-in (step 8), and for example, seven kinds (see FIG. 5) depending on the key release timing are shown in FIG. Since mode 1 is a standby mode, any one of six types of recording end time types will be selected.

That is, in step 9, it is determined whether or not the REC key 1 is turned off, and if it is not turned off, the time setting mode is continued. If it is turned off, then in step 10, the standby state shown in mode 1 of FIG. If the standby is selected, the process returns to the OTR confirmation state of step 5.

When not in the standby state, one of the six types of recording time shown in FIG. 5 is set, so the recording control unit 10 controls the timer 30 to start timing at this OFF timing. Countdown starts. Then, the recording end time selected at this time is displayed on the display 4 as shown in FIG. 4 (b), and this display is also changed according to the countdown.

After shifting to the OTR mode, the recording control unit 10 constantly monitors the output of the timer 30 and determines whether or not the recording end time has been reached (step 12).

Then, before this set time ends, step 13
By inputting the REC key 1 as shown in, it is possible to reset the recording end time.

In the present embodiment, the one-push input of the REC key 1 during recording selects the recording time in any mode in FIG. 5 which is one rank higher than the remaining time.

 Specifically, it is possible to select remaining time 0:20 → ONE PUSH → 0:30 1:45 → ONE PUSH → 2:00 3:01 → ONE PUSH → 4:00.

Further, as shown in step 14, the OTR mode can be released by keying in the stop key 2 or the power key 3, and the power is turned off by operating this key (step 16).

In addition, when the set time for ending recording is reached,
It is determined whether or not a timer recording program is registered (step 15). If there is, a timer recording standby state is set (step 17), and if not, the power is turned off (step 16).

Thus, according to the present embodiment, it is used for normal recording.
After the recording is started by the REC key 1, when the REC key 1 is further operated, the OTR confirmation mode is set and the time can be set by the third key-in to control the start of the countdown of the timer. Therefore, OTR separately
It is possible to set the OTR mode by also using the REC key 1 for normal recording without placing a key.

The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the present invention.

For example, in the above embodiment, after shifting to the normal recording mode, RE
The second operation of the C key puts it in the OTR standby state so that the operator can recognize that the OTR mode is to be entered and that the recording end time must be set thereafter. It is also possible to set the OTR mode by the second operation of the key 1 and immediately shift to the setting of the recording end time.

[Effects of the Invention] As described above, according to the present invention, the RE for normal recording is used.
The C key can also be used to set the OTR mode, reducing the number of keys and facilitating the layout of the front panel.
Even if the number of C key operations increases, it is possible to switch to OTR mode by simply operating a single key multiple times, so the operability does not deteriorate and the key operation can be performed without confusion as much as the number of keys decreases. There is.
