Abstract

PROBLEM TO BE SOLVED: To prevent erroneous record settinq, to unnecessitate complex release operation, and improve operability by enabling to set a reservation start time of video/voice signals only when an output of a record setting permitting means setting and storinq whether record setting of video/voice signals is permittect or not permits record setting. SOLUTION: A record settingpermitting menas 8 decides whether a video/ audio signal from a signal record input terminal of a signal input means 1 is to be recorded or not, and stores permission of record setting. In a signal record setting means 5, a reservation start time of a video/voice signal can be set only when an output of the record setting permitting means 8 permits record setting, and a reservation start time is set based on an output of the record setting permitting means 8. On the contrary, erroneous reservation setting is prevented by setting record operation permissiorx by the record setting permitting means 8, and operability is improved by unnecessitating complex releasing operation.

[0002]

2. Description of the Related Art In recent years, magnetic recording / reproducing apparatuses have been devised to perform recording from various devices.

Hereinafter, a conventional magnetic recording / reproducing apparatus will be described. FIG. 3 is a block diagram showing a configuration of a conventional magnetic recording / reproducing apparatus. In FIG. 3, reference numeral 1 denotes signal input means for selectively inputting one or a plurality of video / audio signals from a signal input terminal or a signal recording input terminal;
Video detecting means for detecting a video / audio signal from the output of
Is a recording means for recording the video / audio signal selected by the signal input means 1, 4 is a clock moving means for moving the current time, 5 is a signal recording setting means for setting a reservation start time of the video / audio signal, 6 is A signal recording start time comparing means 7 for comparing the current time operated by the clock moving means 4 with the start time set by the signal recording setting means 5 and outputting a signal indicating the elapse of the start time, 7 Signal record setting means 5

Means.

The operation of the conventional magnetic recording / reproducing apparatus configured as described above will be described below. First, the signal recording setting unit 5 sets a start time for performing recording based on the presence / absence of a video / audio signal. The recording control means 7 sends an input selection signal of the signal recording input terminal to the signal input means 1 and compares the start time of the clock movement means 4 with the start time of the signal recording setting means 5. When the current time passes the reservation start time, if there is a video as a result of the video detection from the video detection means 2, a recording instruction is sent to the recording means 3 to record the video. Then, when no video is detected as a result of the video detection from the video detection means 2, a recording stop command is sent to the recording means 3 to stop recording.

[0005]

However, in the above-mentioned conventional configuration, there is a case where recording setting is erroneously made.
There is a problem that the canceling method is complicated, such as turning off the power after resetting the timer reservation and setting the timer reservation again.

The present invention solves the above-mentioned conventional problems. By providing the recording setting permission means, if the recording operation permission is set by the recording setting permission means, erroneous recording setting does not occur, and the recording is complicated. An object of the present invention is to provide a magnetic recording / reproducing apparatus in which operability is improved by eliminating the need for a release operation.

[0007]

To achieve this object, a magnetic recording / reproducing apparatus according to the present invention comprises a signal input means for inputting and selecting one or a plurality of signals, and a video input from the signal input means. Video detection means for detecting the presence or absence of a signal;
Recording means for recording the video / audio signal selected by the signal input means, clock hand driving means for moving the current time and outputting current time information, and setting as to whether or not to permit the recording setting of the video / audio signal. Record setting permission means for storing;
Signal recording setting means for setting a reservation start time of a video / audio signal and outputting reservation start time information only when an output of the recording setting permission means permits recording setting;
A signal recording start time for comparing the current time information output from the clock operating means with the reservation start time information output from the signal recording setting means and outputting a signal indicating whether or not the current time has passed the reservation start time. A comparison unit, when the reservation start time is set by the signal recording setting unit, sends an input selection signal to the signal input unit, and when the video detection unit detects that there is a video signal, a video recording command is sent to the recording unit. It has a configuration provided with recording control means for sending.

With this configuration, if the recording operation is set to be prohibited by the recording setting permission means, erroneous recording will not be set, and a complicated release operation will not be required, so that operability can be improved.
