BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic recording / reproducing apparatus used for recording video or audio.

[0002]

2. Description of the Related Art In recent years, a magnetic recording / reproducing device has a built-in timer device and can make a recording reservation.

Hereinafter, a conventional magnetic recording / reproducing apparatus will be described. FIG. 2 shows a block diagram of a conventional magnetic recording / reproducing apparatus. In FIG. 2, reference numeral 21 denotes a clock unit for counting the current time serving as a reference for recording reservation, 22 a channel selection unit for selecting a broadcasting station, and 23 a current unit of the clock unit 21 according to the time signal of the broadcasting station selected by the channel selection unit 22. A time correction unit for correcting the time; 24, an input unit for setting a recording reservation time setting and a time correction broadcasting station; 25, a reservation storage unit for storing the recording reservation time; 26, a current time of the clock unit 21 and the reservation Storage unit 25
A clock discriminating section for comparing the time with the clock time;
A recording command unit 28 for instructing the execution of recording based on the comparison result from the clock unit 21, the channel selection unit 22, the time correction unit 23,
A control unit that controls the input unit 24, the reservation storage unit 25, the time discrimination unit 26, the recording command unit 27, and the clock correction broadcast station storage unit 30, 29 is a mechanism control unit that controls a mechanical system, and 30 is a time correction unit. In the time correction broadcast station storage unit for storing the broadcast stations, the solid arrows indicate the data flow and the broken arrows indicate the control flow.

The operation of the magnetic recording / reproducing apparatus configured as described above will be described below. First, a broadcast station for time correction is input from the input unit 24. The time correction broadcasting station is stored in the time correction broadcasting station storage unit 30. 7
When the time is about 12:00, 12:00 or 19:00, the time correction unit 23
The broadcast station for time correction is sent to the tuning section 22 to tune in.
The time signal is transmitted from the channel selection unit 22 to the time correction unit 23. Therefore, when the voice frequency of the time signal is recognized, the clock unit 21 is operated according to the time signal.
Correct the current time of. When a reservation time is set from the input unit 24, the contents are stored in the reservation storage unit 25. The reservation start time stored in the reservation storage unit 25 is compared with the time of the clock unit 21 for counting the current time. When the current time is several seconds before the reservation start time, a recording command is sent from the recording command unit to the mechanism system control unit 29. It is recorded after the recording preparation time of the mechanism system ends.

[0005]

However, in the above configuration, the recording start time is delayed from the current time by the recording preparation time of the mechanical system. Therefore, the recording must be started several seconds before the recording start time even though the current time is accurate. There was a problem that.

The present invention solves the above-mentioned conventional problems. In the case where a time correction broadcasting station is set, the recording preparation of the mechanical system is made several seconds before the recording start time and the recording is temporarily stopped. It is an object of the present invention to provide a convenient magnetic recording / reproducing apparatus in which recording can be started just at the recording start time.

[0007]

In order to achieve this object, a magnetic recording / reproducing apparatus according to the present invention comprises a clock section for counting a current time serving as a reference for recording reservation, a time setting for recording reservation and a broadcast for time correction. An input section for setting a station, a time correction broadcast station storage section for storing a time correction broadcast station input from the input section, a channel selection section for selecting a broadcast station, and a time correction broadcast station for selection. Station, and then a time correction unit that corrects the current time of the clock unit according to the time signal of the broadcasting station, a reservation storage unit that stores the time of the recording reservation, and a time that compares the current time of the clock unit with the time of the reservation storage unit. A determining unit, a recording command unit for instructing execution of recording based on a comparison result from the time determining unit, a recording pause command unit for instructing the mechanical system control unit to temporarily stop recording before a recording command from the recording command unit, Clock section, tuning section, time correction section, input section Presetting memory unit, the time determination unit, a recording instruction unit, temporary stop command unit records and has the configuration of a control unit for controlling the time correction for broadcasting station storage unit.

[0008]

With this configuration, when the time correction broadcasting station is not set, it is determined that the current time of the clock section is not accurate, and when the current time is several seconds before the reservation start time, a recording command is sent from the recording command section to the mechanical system. The data is sent to the control unit and can be recorded after the recording preparation time of the mechanism system. When the time correction broadcasting station is set, it is determined that the current time of the clock section is accurate, and when the current time is several seconds before the reservation start time, a recording pause command is sent from the recording pause command section to the mechanical system control section. And the mechanism system is in a recording pause state. Thereafter, when the current time falls within the reserved time, a recording command is transmitted from the recording command unit to the mechanical system control unit, and recording can be started just at the recording start time.

[0009]

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

In FIG. 1, 1 is a clock section for counting the current time serving as a reference for recording reservation, 2 is a tuning section for selecting a broadcasting station, 3 is a tuning section for selecting a time correction broadcasting station, Thereafter, a time correction unit for correcting the current time of the clock unit 1 in accordance with the time signal of the broadcasting station, 4 is an input unit for setting a time for recording reservation and setting a broadcasting station for time correction, and 5 is a reservation storage unit for storing the time for recording reservation. , 6 is a time discriminator for comparing the current time of the clock unit with the time of the reservation storage unit, 7 is a recording command unit for instructing execution of recording based on the comparison result from the recording command unit, 8 is a clock unit 1, and a tuning unit. 2, a control unit for controlling a time correction unit 3, an input unit 4, a reservation storage unit 5, a time determination unit 6, a recording command unit 7, a recording temporary stop command unit 10, a time correction broadcast station storage unit 11,
