Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic recording / reproducing apparatus, and more particularly to a magnetic recording / reproducing apparatus suitable for making a recording reservation at the time of timer recording.

[Prior Art] Conventionally, in the recording of a broadcast program by a magnetic recording / reproducing apparatus (VTR), for example, home video technology April 20, 1980
As described in “Recording and Playback of Broadcast Programs”, pages 194 to 196, issued by the Japan Broadcasting Corporation, 1) When recording the program while watching TV, 2) Recording the counterprogram while watching TV Case 3) Timer recording may be performed. When timer recording is performed, the reservation number, day of the week, recording mode (recording Tape speed), start time, and end time.

FIG. 2 shows a conventional example. A reservation number, a day of the week, a recording mode (recording tape speed), a start time, and an end time are input to the timer circuit 6 by the operation buttons 5. When the recording start time comes, the timer circuit controls the tuner 2 to select a station. The signal is input to the signal circuit 3 through the antenna 1 and the tuner 2. The signal circuit 3 records a signal on a magnetic tape (not shown) via the head 4. At the recording end time, the timer circuit 6 controls the tuner 2 and the signal circuit 3 to end the recording.

[Problems to be Solved by the Invention] In the above-mentioned conventional technology, even if a reservation is set, it is not immediately known how long the actual reservation recording time is. Calculating time is very cumbersome. Further, when a plurality of recording tape speeds are combined, the calculation becomes further complicated, and unless converted into a tape consumption amount, it is not known how long a tape having a recording time should be used.

In addition, when the total tape consumption exceeds the recordable time of the used tape in the standard mode, it is very difficult to determine which reserved recording tape speed setting should be changed to the long-time recording mode. Further, changing the tape speed once set is also a troublesome task.

Accordingly, a first object of the present invention is to provide a material for determining which tape should be used by displaying the total reservation time and the total tape consumption of the set reservation.

A second object of the present invention is to display how long a tape should be used for recording (recording) (a type of cassette tape that can be recorded).

A third object of the present invention is to change the automatically set recording (recording) tape speed when the total tape consumption exceeds the recording (recording) time of the used tape.

A fourth object of the present invention is to use a switch to select whether or not to change the automatically set recording (recording) tape speed when the total tape consumption exceeds the recording (recording) time of the used tape. It is in.

It is another object of the present invention to notify which reservation recording (recording) tape speed should be changed when the total reservation time exceeds the recording (recording) time of the used tape.

[Means for Solving the Problems] In order to achieve the above object, the present invention employs the following configuration.

In a magnetic recording / reproducing apparatus that performs timer recording by setting a plurality of reserved recording times and a recording tape speed mode of each of the reserved recordings, a total reserved recording time and a total tape consumption that are reserved are calculated and displayed. Compares the tape consumption with the tape length of multiple standard tape cassettes, finds and displays the shortest standard tape cassette that can be recorded, and sets the total tape consumption for multiple reservations in the standard tape speed mode. When the tape length of the standard tape cassette is exceeded, whether to change the reserved recording tape speed mode to the long-time tape speed mode by the operation means as appropriate or to automatically reset the predetermined reservation to the long-time speed mode , A magnetic recording / reproducing device that can be manually selected.

[Operation] An operation based on the above configuration will be described.

According to the present invention, in a magnetic recording / reproducing apparatus that has a reservation recording (recording) function and performs recording / reproduction using a magnetic tape, when performing reservation setting, the total reservation time and total tape consumption of the set reservation are reduced. Since the display circuit is provided, when a plurality of reservations are made, the total reservation time and the total tape consumption can be immediately known.

According to the present invention, in a magnetic recording / reproducing apparatus which has a recording function (recording) and performs recording / reproducing using a magnetic tape, the type of usable magnetic tape is displayed based on the total tape consumption by reservation. Immediately,
You can select the required magnetic tape (type of tape cassette).

According to the present invention, in a magnetic recording / reproducing apparatus having a reserved video recording (recording) function and performing recording / reproduction using a magnetic tape, when the total tape consumption of the reservation exceeds the used tape length, the total tape consumption is reduced. Be careful not to exceed the used tape length.
Since a circuit for automatically setting a reservation is provided, it is not necessary to determine which recording (recording) tape speed setting of a reservation should be changed to a long-time recording (recording) mode.

In addition, since a switch is provided for selecting whether or not to automatically reset (reset) the recording tape speed of the reservation, when the switch is turned off (the side on which automatic resetting is not performed) In this case, the operator can manually reset the recording tape speed of an arbitrary program or cancel the reservation of a part of the program.

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

In FIG. 1, reference numeral 1 denotes an antenna, 2 denotes a tuner, 3 denotes a signal circuit, 4 denotes a head, 5 denotes an operation button, and 6 denotes a timer circuit. The above components are the same as those in FIG. In this embodiment, an arithmetic circuit 7, a comparison circuit 8, a display circuit 9, and a control circuit 10 are added to the conventional example shown in FIG. First, the timer circuit 6 sends the reservation number, the day of the week, the recording mode (recording tape speed), the start time, and the end time input by the operation buttons 5 to the arithmetic circuit 7. The arithmetic circuit 7 calculates the recording time from the start time and the end time for each reservation number, and calculates the tape consumption (tape length) from the recording mode.

Then, the total recording time and the total tape consumption are obtained from the recording time and the tape consumption of each reservation. For example, the total reservation time is obtained by adding the recording times of the respective reservations, and the tape consumption of each reservation obtained in consideration of the recording tape speed is added, or the total reservation time and the recording tape speed are considered. To determine the total tape consumption.

Next, the comparison circuit 8 compares the standard tape cassette length, such as 60 minutes or 120 minutes, with the total tape consumption determined by the arithmetic circuit 7, and determines the type of the shortest tape (tape cassette) that can be recorded. Ask. The display circuit 9 displays a recording time, a tape consumption amount, a total recording time, a total tape consumption amount, an optimum tape type, and the like for each reservation.

If the total tape consumption in the standard mode exceeds the length of the standard tape used (for example, a 120-minute tape) set by the user, the control circuit 10 reserves the long-time recording mode in order from the last program of the reservation execution. The timer circuit 6 is controlled so that is reset. The switching switch 11 switches between performing the resetting automatically and selectively using the operation buttons.
The operation of the timer circuit 6 at the start and end of recording is the same as that of the related art.

In this embodiment, when the total tape consumption exceeds the length of the standard use tape, the reservation is reset to the long-time recording mode in order from the last program of the reservation execution. The reservations may be reset in order from the reserved program set in.

Also, in the present embodiment, an arithmetic circuit separately from the timer circuit,
Although the comparison circuit and the like are provided, it can also be realized by software using a microcomputer together with the timer circuit.

When the switch 11 is switched and resetting is performed manually using the operation buttons, it is necessary to increase the recording tape speed of which reserved program or which and which reserved program so that the total tape consumption does not exceed the used tape length. The mode can be changed, or a reserved program or a combination thereof can be displayed on the display circuit.

[Effects of the Invention] The present invention relates to a magnetic recording / reproducing apparatus that has a reservation recording (recording) function and performs recording and reproduction using a magnetic tape. Since the circuit for displaying the consumption amount is provided, when a plurality of reservations are made, the total reservation time and the total tape consumption amount can be immediately known.
