Abstract

PURPOSE:To set a mechanical part in a reproducing mode and to simplify the jump of information by operating a fast forwarding key or a rewinding key once regardless of the set mode of the mechanical part. CONSTITUTION:An operation part 1 is provided with the fast forwarding FF key and the rewinding REW key and the mechanical part(mech. part) 5 reproduces information recorded on a recording medium. The input of operation by the FF key or the REW key is performed in a state where an FF mode or an REW mode is set. Then, the mechanical part 5 is set in a mode in which the information in a forward direction and a backward direction recorded on the recording medium is retrieved by jumping the information as much as the input of operation. When the input of operation by the rewinding key is performed in a state where the mechanical part 5 is set in such a mode or when the input of operation by the fast forwarding key is performed in a state where the mechanical part 5 is set in the rewinding mode or in the mode in which the head of the information in the backward direction is retrieved, a control part 7 sets the mechanical part 5 in the reproducing mode. At such a time, the mechanical part 5 is easily set in the reproducing mode and the jump of the information is performed just by operating the FF key or the REW key of the operation part 1 once whatever mode the mechanical part 5 is set in.

Next, the operation will be explained.

First, when the C cassette half is inserted into the cassette holder of the cassette loading mechanism 4 from the cassette insertion slot, the control unit 7 determines whether the C cassette half It detects that it has been inserted into the holder (step 5).
TI), the cassette loading mechanism 4 is operated to load the C cassette half (step 5T2).

Then, when the second cassette detector 3 detects that the C cassette half is attached to the mechanical section 5 based on the detection signal that detects the C cassette half (step 5T3), the cassette loading mechanism 4 is stopped, and The mechanical section 5 is set to the playback mode, and the magnetic head 5a starts playing back the music information recorded on the magnetic tape (step 5T4).

While the music information recorded on the magnetic tape is being played back in this way, it is determined whether the eject key of the operating section 1 has been operated (step 5T5). If the eject key has been operated, the mechanical section 5 is activated. After stopping, the cassette loading mechanism 4 is activated to unload the C cassette half (step 5T6).

Then, the first thing I heard was that the C cassette half was ejected.
When it is detected based on the non-detection signal outputted by the cassette detector 2 (step 5T7), the cassette loading mechanism 4 is stopped (step 5T8), and then step ST
Proceed to I.

Further, if the eject key is not operated in the determination in step ST5, it is determined whether the FF key has been operated (step 5T9), and if the FF key has been operated, the mechanical section 5 is set to F" mode (step 5TIO).

Then, when the FF key is operated again (step 5TI
I) After setting the mechanical section 5 to the music search mode (step 5T12), it is determined whether cueing has been completed based on the output of the magnetic head 5a (step 5T).
13).

Note that this cue determination is performed, for example, by detecting unrecorded portions provided between songs.

If it is determined in step 5T13 that cueing is not completed, it is further determined whether the FF key has been operated (step 5T14), and if the FF key has not been operated,
The process proceeds to step 5T13, and if the FF key has been operated, or if the cue has been found and completed as determined in step 5T13, the process proceeds to step ST4.

Further, if the FF key has not been operated in the determination in step ST9, it is determined whether the REW key has been operated (step 5T15), and if the REW key has not been operated,
Proceeding to step ST4, if the REW key is operated, the mechanical section 5 is set to REW mode (step 5T1
6).

Subsequent steps 5717 to 5T20 are the same as step 5 described above.
Since it is the same as T11 to 5T14, the explanation will be omitted.

[Problem to be solved by the invention]

Since the conventional recording medium playback device is configured as described above, in order to switch from the FF mode or REW mode to the playback mode, press the FF key or REW key on the operation unit 1.
It is necessary to press the key twice.

Further, if the operation section 1 is provided with a playback key, the playback mode can be changed from the FF mode or the REW mode by operating the playback key, but the number of keys provided on the operation section 1 increases.

Furthermore, if you want to search for music a few songs ahead or a few songs later, you can repeat the music search several times by operating the FF key or REW key, or use the FF key in advance.
key or REV key to enter FF mode or RE
After sending the magnetic tape in the W mode, it is necessary to perform a music search by operating the FF key or REW key, which makes the operation complicated.

This invention was made to solve the above-mentioned inconveniences, and it is possible to reduce the number of keys on the operation section, and to switch from FF mode or REW mode to playback mode by operating the REW key or FF key once. To provide a recording medium playback device that can be set and easily perform a Z knee search that skips over a plurality of songs.

[Means to solve the problem]

The recording medium playback device according to the present invention has the mechanical section set to the FF mode or REW mode based on the operation input of the FF key or the REW key.
When there is an EW key operation input, the mechanical part enters the music search mode, which searches for the beginning of information in the forward or backward direction of information recorded on the recording medium, skipping information by the number of FF key or REW key operation inputs. When the REV key is input while the mechanical section is in the FF mode or the music search mode that searches for the beginning of information recorded on the recording medium in the forward direction, the mechanical section switches to the REW mode or The apparatus includes a control section that sets the mechanical section to a reproduction mode when an FF key operation is input in a music search mode in which the beginning of information in the backward direction of information recorded on a recording medium is searched.

[For production]

The control section of the recording medium playback device according to the present invention controls the mechanical section to FF based on the operation input of the FF key or the REW key.
mode or REW mode, if there is an FF key or REV key operation input, the information recorded on the recording medium will be moved forward or backward by the number of FF key or REW key operation inputs. Set the mechanical part to music search mode, which searches for the beginning of the information.

In addition, when the mechanical section is in the FF mode or the music search mode that searches for the beginning of information recorded on the recording medium in the forward direction, if the REW key is input, the mechanical section switches to the REW mode or the recording medium. When the REW key is operated in the music search mode for searching for the beginning of information recorded in the backward direction, the mechanical section is set to the playback mode.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

FIGS. 1A and 1B are flowcharts for explaining an example of the operation of a vehicle-mounted C cassette player according to an embodiment of the recording medium reproducing apparatus of the present invention.

In Fig. 1 (a) and (b), 5T21-ST5
2 indicates each step.

The configuration of the in-vehicle C cassette player according to this embodiment is the same as that shown in the block diagram of FIG. 2, except that the control of the control section 7 is different.

Next, the operation will be explained.

Note that the explanation of steps 5T21 to 5T28 is the same as that of the conventional example, so the explanation will be omitted.

First, if it is determined in step 5T25 that the eject key has not been operated, it is determined whether the FF key has been operated (step 5T29), and if the FF key has been operated, after setting the mechanical section 5 to the FF mode ( Step 5T3
Step 5T31) If the FF key is not operated,
Determine whether the REW key has been operated (step 5T3
2).

If it is determined in step 5T32 that the REW key has been operated, the process proceeds to step 5T24, and if the REW key has not been operated, it is further determined whether the FF key has been operated (step 5T33), and the FF key has been operated. If not, the process advances to step 5T32.

Next, if the FF key is operated in the judgment at step 5T33 or step 5T31, the value n of the built-in memory is
1, and after setting the mechanical section 5 to the music search mode (step 5T34), it is determined whether a song interval (unrecorded portion) has been detected based on the output of the magnetic head 5a.Step 5T35), a song interval is detected. If not, F
Determine whether the F key has been operated (step 5T36
).

If it is determined in step 5T36 that the FF key has been operated, the memory value n is incremented by one (step S
↑37), proceed to step 5T35, and if the FF key has not been operated, determine whether the REW key has been operated.Step 5T38), if the REW key has been operated, proceed to step 5T35, and determine whether the REW key has been operated. If not, proceed to step 5T24.

In addition, if an interval between songs is detected in the determination at step 5T35, after decreasing the memory value n by 1 (step 5T39
), it is determined whether the memory value n is zero (step 5T40); if the memory value n is not zero, the process proceeds to step 5T35; if the memory value n is zero, the process proceeds to step 5T24.

Next, if it is determined in step 5T29 that the FF key has not been operated, it is determined whether the REW key has been operated (step 5T41), and if the REW key has not been operated, the process proceeds to step 5T24, in which it is determined whether the REW key has been operated. If so, set the mechanical section 5 to REW mode (step 5).
T42).

Subsequent steps 5T43 to 5T52 are the same as step 5 described above.
Since it is the same as T31 to 5T40, the explanation will be omitted.

As mentioned above, the controller 7 controls the cassette loading mechanism 4 based on each input. Since the mechanical section 5 is controlled, the operation section 1
By operating the FF key or REW key, you can easily search for a few songs later or several songs later.

Regardless of which mode the mechanical section 5 is set to, the mechanical section 5 can be set to the reproduction mode by operating the FF key or the REW key once.

Therefore, the number of keys on the operation unit 1 can be reduced, making operation easier, and when applied to a remote control device, the remote control device can be made smaller.

Although the operation of the display unit 6 was not explained in the above-described embodiment, messages such as music information, music search, and operation are displayed.

Further, although the explanation has been given using a car-mounted C cassette player as an example, it goes without saying that the present invention is not limited to car-mounted use, and can also be applied to digital audio tape players, compact disc players, etc.

〔Effect of the invention〕

As described above, according to the present invention, when a fast-forward key or a rewind key is operated while the mechanical section is in the fast-forward mode or rewind mode, the mechanical section displays information equal to the number of times the fast-forward key or rewind key is operated. Search for the beginning of the skipped information. q jL-Thick search mode is set, and when the mechanical section is in fast forward mode 2 rewind mode or music search mode, when the corresponding rewind key or fast forward key is operated, the mechanical section is set to playback mode, so fast forwarding is possible. By operating the key or rewind key, you can easily search for the next or next song.

And no matter which mode the mechanical part is set to,
By operating the fast forward or rewind key once, the mechanical section can be set to playback mode.

Therefore, the number of keys on the operating section can be reduced, making operation easier, and when applied to a remote control device, the remote control device can be made smaller.
