[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic recording / reproducing apparatus such as a video tape recorder (hereinafter abbreviated as "VTR") capable of reserved recording.

[0002]

2. Description of the Related Art In recent years, a magnetic recording / reproducing apparatus has been devised for recording from various external devices.

A conventional magnetic recording / reproducing apparatus will be described below with reference to FIG. FIG. 4 is a block diagram showing a configuration of a conventional magnetic recording / reproducing apparatus. Reference numeral 1 denotes a video detecting means for detecting presence or absence of a video / audio signal with respect to a signal input from the first external signal input terminal 11 and outputting detection information 101 indicating the content thereof, and 2 denotes an input from the first external signal input terminal 11 External signal recording setting means for outputting mode setting information 102 indicating whether or not an operator has performed a setting operation to record a signal to be recorded;
And mode setting information 10 from the external signal recording setting means 2
Mode control means 4 for inputting 2 and outputting input selection information 103 and mode control information 104, which will be described later, and inputs the external signals from the first external signal input terminal 11 and the second external signal input terminal 12 An external signal selecting means for selecting an external signal in accordance with the input selection information 103 from the control means 3 and outputting a selected external signal 105 as the selected external signal.
05 and mode control information 104 from the mode control means 3
And the mode control information 1 for the selected external signal 105
This is a mode executing means for selecting and executing a mode in accordance with the mode 04. Here, the mode means the contents of each operation mode such as recording, stopping recording, reproducing, fast-forwarding, rewinding, and taking out a cassette.

Next, the mode control means 3 will be described with reference to FIG. FIG. 5 is an output state diagram of the mode control means 3 in the conventional magnetic recording / reproducing apparatus. FIG. 5 shows the contents of the input selection information 103 or the mode control information 104 determined and output by the mode setting information 102 and the detection information 101 indicating the presence or absence of the video / audio signal before and after the setting operation in the external signal recording setting means 2. Here, the input selection information 103 is “CH” and the mode control information 104
Is abbreviated as “mode”. Also, "free" means that it can be set arbitrarily. For example, “CH: free” means that the signal from the first external signal input terminal 11 or the second external signal input terminal 12 can be arbitrarily selected. Also, “mode: free” means that the user can arbitrarily select any of the modes such as recording, playback, fast forward, rewind, stop recording, and taking out a cassette.

The operation of the conventional magnetic recording / reproducing apparatus configured as described above will be described below. First, consider a case where the setting operation of the external signal recording setting means 2 is not performed. In this state, other information (not shown) has been input to the mode control means 3. Based on this information, the mode control means 3 sends the input selection information 103 and the mode control information 10
4 is output, and the movements of the external signal selecting means 4 and the mode executing means 5 are determined accordingly. For example, if the video / audio signal from the second external signal input terminal 12 is selected by the external signal selection means 4 and the reproduction mode is set by the mode execution means 5, the video / audio signal from the second external signal input terminal 12 is selected. The reproduction of the signal is performed.

Next, consider a case where a setting operation of the external signal recording setting means 2 is performed. At this time, the mode setting information 10 indicating the recording command of the signal from the first external signal input terminal 11
2 is sent to the mode control means 3. From the mode control means 3, input selection information 103 for instructing selection of a signal from the first external signal input terminal 11 is sent to the external signal selection means 4. The external signal selecting means 4 selects and outputs a signal from the first external signal input terminal 11 based on the input selection information 103. If there is no video / audio signal in the signal input from the first external signal input terminal 11, the video detection means 1
, Detection information 101 indicating that there is no video / audio signal is sent to the mode control means 3, and a mode control signal 104 for selecting and instructing the recording stop mode is sent from the mode control means 3 to the mode execution means 5. The mode execution means 5 executes a recording stop mode. In this case, the signal from the first external signal input terminal 11 is selected, but the recording is stopped. At this time, other modes such as reproduction cannot be selected. Next, when a video / audio signal is input from the first external signal input terminal 11, detection information 101 indicating the presence of a video / audio signal is sent from the video detection means 1 to the mode control means 3, and from the mode control means 3, A mode control signal 104 for instructing a recording mode is sent to the mode execution means 5.
The mode execution means 5 executes a recording mode. In this case, the video and audio signals from the first external signal input terminal 11 are recorded.

[0007]

However, the above-mentioned conventional configuration has the following problems.

That is, when the operator performs a setting operation using the external signal recording setting means 2, the first external signal input terminal 11
Mode execution means 5 until a video / audio signal is input from
In, the recording stop mode is forcibly selected. For this reason, there is a problem that even if it is desired to execute another mode, for example, a reproduction mode or a cassette tape take-out mode, before the video / audio signal is input, the user cannot select those modes.

[0009] The present invention solves the above-mentioned conventional problems. In the setting operation of the operator, the reservation start time is not set, and the recording stop mode is not forcibly selected until the reservation start time. It is an object of the present invention to provide a magnetic recording / reproducing apparatus in which selection is arbitrary.

[0010]

In order to achieve this object, a magnetic recording / reproducing apparatus according to the present invention detects presence / absence of a video / audio signal in a signal input from a first external signal input terminal and outputs detection information. Signal detection means, clock movement means for outputting current time information, and external signal reservation for outputting reservation mode setting information including information indicating whether a reservation start time and a setting operation have been performed based on an operator's setting operation. Input recording setting means, detection information, current time information, and reservation mode setting information. If the setting operation of the external signal reservation recording setting means has been performed and the current time information is before the reservation start time has elapsed, the reservation is made. Outputting mode control information not determined by the mode setting information, the detection information, or the current time information, and outputting the first external signal when the current time information is after the elapse of the reservation start time. Input selection information for selecting and instructing a signal input from the input terminal is output. If the detection information indicates that there is no video / audio signal, mode control information for instructing a recording stop mode is output, and the detection information is video / audio. A reservation mode control means for outputting mode control information for instructing selection of a recording mode when a signal is present; and a signal and input selection information from a first external signal input terminal and a second external signal input terminal. External signal selecting means for inputting and outputting a selected external signal selected according to the input selection information,
A mode execution unit that inputs a selection external signal and mode control information and executes a mode selected in accordance with the mode control information.

With this configuration, the reservation start time is not set in the setting operation of the operator, and the recording stop mode is not forcibly selected when the current time information is before the elapse of the reservation start time. The mode can be arbitrarily selected.

[0012]

Alternatively, the content of the mode control information 104 is shown. Here, the input selection information 103 is “CH” and the mode control information 10
4 is abbreviated as “mode”. Also, "free" means that it can be set arbitrarily. For example, “CH: free” means that the signal from the first external signal input terminal 11 or the second external signal input terminal 12 can be arbitrarily selected. In addition, "mode: free" means that any mode can be arbitrarily selected from among modes such as recording, playback, fast forward, rewind, stop recording, and taking out a cassette.

The operation will be described below. Here, the current time information is set to t. First, consider a case where the setting operation of the external signal reservation recording setting means 7 is not performed. The reservation mode setting information 106 at this time indicates that the setting operation of the external signal recording setting means 7 has not been performed. In this state, other information (not shown) not determined by the reservation mode setting information 106, the detection information 101, or the current time information 107 has been input to the reservation mode control means 8. Based on this information, the reservation mode control means 8 outputs the input selection information 103 and the mode control information 104,
In response to this, the external signal selecting means 4 and the mode executing means 5
Is determined. For example, it is assumed that the video / audio signal from the second external signal input terminal 12 is selected by the external signal selection means 4 and the reproduction mode is set by the mode execution means 5.
In this case, the reproduction of the video / audio signal from the second external signal input terminal 12 is performed. In FIG. 2, "CH:
Freedom "and" Mode: Freedom ".

Next, it is assumed that the setting operation of the external signal reservation recording setting means 7 is performed and the reservation start time T is set. As a result, the reservation mode setting information 106 including the reservation start time T and information indicating that the setting operation has been performed is sent to the reservation mode control means 8.

First, consider the case where the current time information t is before the elapse of the reservation start time T. In this case, the reservation mode control means 8 sends the input selection information 103 for selecting and instructing the signal from the first external signal input terminal 11 to the external signal selection means 4, and the reservation mode setting information 106, the detection information 101 or the current time. Mode control information 104 based on other information (not shown) not determined by information 107 is sent to mode execution means 5.

Next, consider the case where the current time information t is after the elapse of the reservation start time T. Here, a case is considered in which a signal input from the first external signal input terminal 11 has no video / audio signal. Input selection information 1 for selecting and instructing a signal from the first external signal input terminal 11 from the reservation mode control means 8
03 is sent to the external signal selection means 4 and the detection information 10
Since 1 indicates no video / audio information, a mode control signal 104 for selecting and instructing the recording stop mode is sent to the mode execution means 5. In the external signal selection means 4, the input selection information 1
03, a signal from the first external signal input terminal 11 is forcibly selected and output. The mode execution means 5 forcibly executes the recording stop mode. In this case, the signal from the first external signal input terminal 11 is selected, but the recording is stopped. At this time, other modes such as reproduction cannot be selected. In FIG. 2, "CH: first external signal" and "mode: stop recording" are shown. Next, a case where a video / audio signal is input from the first external signal input terminal 11 will be considered. The detection information 101 indicates that there is a video / audio signal, and the mode control signal 104 for selecting the recording mode is sent from the reservation mode control means 8 to the mode execution means 5. The mode execution means 5 executes a recording mode. In this case, the video and audio signals from the first external signal input terminal 11 are recorded. In this case, FIG.
H: first external signal "and" mode: recording ".

As described above, according to the present embodiment, the reservation mode control is performed when the setting operation of the external signal reservation recording setting means 7 is performed and the current time information is before the reservation start time has elapsed. Input selection information 103 for selecting and instructing a signal from the first external signal input terminal 11 is sent from the means 8 to the external signal selection means 4, and is not determined by the reservation mode setting information 106, the detection information 101 or the current time information 107. Mode control information 1 based on other information (not shown)
Since the signal 04 is sent to the mode execution means 5, it is not necessary to select a new input signal, and the mode is not forcibly selected. Can be reproduced.

On the other hand, after the setting operation of the external signal reservation recording setting means 7 has been performed and the current time information is before the elapse of the reservation start time, the reservation mode control means 8 transmits to the external signal selection means 4. Even if the input selection information 103 is not limited, the mode control information 10 based on the reservation mode setting information 106, the detection information 101, or other information (not shown) not determined by the current time information 107.
By sending 4 to the mode execution means 5, an arbitrarily selected mode can be executed.

Here, the input selection information 103 is abbreviated as “CH” and the mode control information 104 is abbreviated as “mode”. Also, "free" means that it can be set arbitrarily. For example, if "CH: Free", the first
Means that the signal from the external signal input terminal 11 or the second external signal input terminal 12 can be arbitrarily selected.
In addition, "mode: free" means that any mode can be arbitrarily selected from among modes such as recording, playback, fast forward, rewind, stop recording, and taking out a cassette.

The operation will be described below. Here, the current time information is set to t.

In this state, other information (not shown) not determined by the reservation mode setting information 106, the detection information 101, or the current time information 107 has been input to the reservation mode control means 8. Based on this information, the reservation mode control means 8 outputs the input selection information 103 and the mode control information 104,
In response to this, the external signal selecting means 4 and the mode executing means 5
Is determined. For example, it is assumed that the video / audio signal from the second external signal input terminal 12 is selected by the external signal selection means 4 and the reproduction mode is set by the mode execution means 5.
In this case, the reproduction of the video / audio signal from the second external signal input terminal 12 is performed. In FIG. 3, "CH:

It is sent to the means 4 and the mode execution means 5. The external signal selecting means 4 selects an external signal according to the input selection information 103 and outputs a selected external signal 105. The mode executing means 5 selects and executes a mode according to the mode control information 104. FIG. 3 shows this case as “CH: free” and “mode: free”.

Next, consider a case where the current time information t is after the elapse of the reservation start time T.

03, a signal from the first external signal input terminal 11 is forcibly selected and output. The mode execution means 5 forcibly executes the recording stop mode. In this case, the signal from the first external signal input terminal 11 is selected, but the recording is stopped. At this time, other modes such as reproduction cannot be selected. FIG. 3 shows “CH: first external signal” and “mode: stop recording”. Next, a case where a video / audio signal is input from the first external signal input terminal 11 will be considered.
