Abstract

PURPOSE:To reduce the number of keys to be provided to an operation part by constituting the subject device in such a manner that a mechanism part is turned to a reproducing mode when a number obtained by deducting operation times of an REW key or/and a number of information interval signals from a magnetic head from operation times of an FF key becomes zero during an FF mode of the mechanism part. CONSTITUTION:When the number obtained by deducting the operation times of the REW (rewinding) key 1B or/and the number of information interval signals from the magnetic had 3A from the operation times of the FF key 1A becomes zero during the FF (fast forward) mode of the mechanism part 3, the mechanism part 3 is turned to the reproducing mode. Then, when a number obtained by deducting the operation times of the FF key 1A or/and the number of the information interval signals from the operation times of the REW key 1B becomes zero during the REW mode of the mechanism part 3, the mechanism part is turned to the reproducing mode. Thus, by performing a jumping search with such simple operations of the FF key 1A and the REW key 1B, the number of keys to be provided to the operation part 1 can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a magnetic recording and reproducing device that can select a song by skipping over a plurality of pieces of information to be reproduced (hereinafter, the information will be described as music information).

[Conventional technology]

Conventional magnetic recording media playback devices, such as magnetic recording and playback devices, run a magnetic tape housed in a cassette half loaded in a mechanical section, and play music information recorded on the magnetic tape. , Fast forward key (FF key) 9 Rewind key (REW key) provided on the operation panel
There is one that allows you to select music information by operating only the button.

To explain an example of such a magnetic recording/reproducing device, if the FF key is operated while the mechanical part is in playback mode, the mechanical part goes into fast forward mode (FF mode), and if the FF key is operated while the mechanical part is in FF mode. Then, the mechanical section enters a one-track fast-forward search mode to search for the beginning of the next music information, and when the FF key is operated while the mechanical section is in the one-track fast-forward search mode, the mechanical section enters a playback mode.

If you operate the REW key while the mechanical unit is in playback mode, the mechanical unit will go into rewind mode (REW mode), and if you operate the REW key while the mechanical unit is in REW mode, the mechanical unit will switch back to the music that was being played. A one-track rewind search mode is entered to search for the beginning of information, and when the REW key is operated while the mechanical section is in the one-track rewind search mode, the mechanical section enters a playback mode.

If you operate the FF key when the mechanical section is in REW mode or one-track rewind search mode, the mechanical section will go into FF mode, and if you operate the REW key when the mechanical section is in FF mode or one-track fast forward search mode, The mechanical part is RE
It becomes W mode.

Therefore, by operating the FF key or the REW key while music information is being reproduced, the beginning of the next music information or the beginning of the music information that was being reproduced can be searched and reproduced.

[Problem to be solved by the invention]

Since the conventional magnetic recording medium playback device is configured as described above, by operating the FF key and the REW key, the beginning of the next music information or the beginning of the music information that was being played back can be searched and played back. However, in the case of an interleaved search that plays back music information that has moved forward multiple screens or multiple songs, it is necessary to repeat the search operation or use the FF and REW keys to advance several songs before performing the search operation. However, there was a problem that the operation became complicated.

Therefore, in order to resolve this inconvenience, it may be possible to provide a search key for searching on the operation panel so that the interleaved search operation can be performed easily, but this would require a large number of keys to be provided on the operation panel. There was an inconvenience.

This invention was made in order to solve the above-mentioned disadvantages, and it is possible to reduce the number of keys provided on the operation unit, and also to provide a magnetic recording system that allows interlacing searches by simply operating the FF key and REW key. The present invention provides a media playback device.

[Means to solve the problem]

The magnetic recording medium reproducing device according to the present invention includes FF-1-
- an operation section having a REW key, a mechanical section that runs the magnetic tape housed in the cassette half and reproduces information recorded on the magnetic tape with a magnetic head, and a mechanical section that operates based on the output of the control section. At the same time, when the mechanical part is in FF mode, the REW function is
When the number of key operations and/or the number of inter-information signals from the magnetic head becomes zero, or when the mechanical section is in REW mode, the number of REW key operations minus F
The controller is configured to put the mechanical section into playback mode when the number of F key operations and/or the number of inter-information signals becomes zero.

[For production]

The control section of the magnetic recording medium reproducing apparatus according to the present invention, when the mechanical section is in the FF mode, calculates R from the number of operations of the FF key.
When the number of operations of the EW key and/or the number of inter-information signals from the magnetic head becomes zero, the mechanical section is put into the reproduction mode.

Then, when the mechanical section is in the REW mode, the number of operations of the REW key minus the number of operations of the FF key and/or the number of inter-information signals becomes zero (7), and the mechanical section is placed in the reproduction mode.

First, when the mechanical section 3 is controlled to load the cassette half with the cassette loading mechanism and the recording/playback mechanism is loaded, the flowchart shown in Fig. 2 starts, and the music information recorded on the magnetic tape stored in the cassette half is started. After setting the mechanical section 3 to the playback mode for playback (step 5TI), it is determined whether the eject key IC of the operation section 1 has been operated (step 5T2).

If it is determined in step ST2 that the eject key IC has not been operated, it is determined whether the FF key IA has been operated (step 5T3), and if the FF key IA has been operated, for example, the value NF of the built-in counter is set to zero. After setting the mechanical part 3 to FF mode (step 5T4
), and further determines whether the FF key IA has been operated (step 5T5).

Furthermore, if the FF key IA is operated in the determination at step ST5, the value N is increased by one (step ST5T).
6), return to step ST5.

However, if the FF key IA is not operated in step ST5, it is determined whether the REW key IB is operated (step 5T7), and if the REW key IB is not operated, it is determined whether the value NF is zero. Step 5
T8), if the value N is zero, the process returns to step ST5.

If the value NF is not zero in the judgment in step ST8, then there is a non-recorded part (between songs) provided between the music information recorded on the magnetic tape, or between the information where the start ID of the DAT format is reproduced. In step 5T9), it is determined whether a signal (inter-song signal; a signal in which no signal continues for a predetermined period of time, for example, 3 to 4 seconds in playback mode, or a start 10 signal) is supplied from the magnetic head 3A. If not supplied, the process returns to step ST5.

Furthermore, if the inter-song signal is supplied in the determination of step ST9, or if the REW key IB is supplied in the determination of step ST7,
If the value N is operated, after decreasing the value NF by one (step 5TIO), it is determined whether the value N is less than or equal to zero (step 5TII). If the value N is less than or equal to zero, then
Returning to step STI, if the value NF is not less than zero,
Return to step ST5.

Further, if it is determined in step ST3 that the FF key IA is not operated, it is determined whether the REW key IB is operated (step 5T12), and if the REW key IB is not operated, the process returns to step STI and the REW key IB is If it has been operated, the counter value NR is set to zero and the mechanical section 3 is set to REW mode (step 5T13).
), and further determines whether the REW key IB has been operated (step 5T14).

If it is determined in step 5T14 that the REW key 18 has been operated, the value NIl is incremented by one (step 5T15), and then the process returns to step 5T14.

However, if the REW key IB is not operated in step 5T14, it is determined whether the FF key IA is operated (step 5T16), and if the FF key IA is not operated, it is determined whether the value NR is zero. Step 5T17) If the value N is zero, step 5
Return to T14.

If the value NR is not zero in step 5T17, it is determined whether the inter-track signal is supplied from the magnetic head 3A (step 5T18), and if the inter-track signal is not supplied, the process goes to step ST'l4. return.

Furthermore, if the intercostal signal is supplied in the determination of step 5TIB, or if the FF key I is supplied in the determination of step 5T16,
If A has been operated, after decreasing the value NR by one (step S↑19), it is determined whether the value N8 is less than or equal to zero (step 5T20). If the value NR is less than or equal to zero,
Returning to step STI, if the value NR is not less than zero,
Return to step 5T14.

Further, if the eject key IC is operated as determined in step ST2, the cassette loading mechanism unloads the cassette half from the recording/reproducing mechanism and ejects the cassette half (step 5T21), and the control ends.

In this way, according to the above-described embodiment, music information can be reproduced by performing an interlaced search simply by operating the FF primary key A and the REW key IB, without providing a search key or the like on the operation unit 1.

Therefore, the number of keys provided on the operation unit 1 can be reduced, and the number of keys provided on the remote control device that remotely controls the magnetic recording and reproducing device can also be reduced.

Although the description of the display unit 4 is omitted in the above embodiment, when the control unit 2 controls the mechanical unit 3 as described above, at least the values N, , NIl are displayed to indicate the destination to be searched. do.

Although the description has been made regarding a magnetic recording/reproducing device for a multilayered tower, it goes without saying that the present invention can also be applied to other magnetic recording medium reproducing devices.

Furthermore, the information recorded on the magnetic recording medium is not limited to music information, and may be other information.

〔Effect of the invention〕

As described above, according to the present invention, when the mechanical section is in the FF mode, the number of FF key operations minus the number of REW primary key operations and/or the number of inter-information signals from the magnetic head becomes zero. or when the number of REW key operations minus the number of FF key operations and/or the number of inter-information signals becomes zero when the mechanical section is in REW mode, the mechanical section is set to playback mode. Therefore, there is an effect that information can be reproduced by performing an interlaced search with a simple operation of operating the FF key and REW key.

Therefore, the number of keys provided on the operation section can be reduced.

Further, there is an effect that the number of keys provided on a remote control device that remotely controls the magnetic recording medium reproducing device can also be reduced.
