[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a signal reproducing apparatus and method for storing a plurality of signal recording media and reproducing information signals recorded on the stored signal recording media.

[0002]

2. Description of the Related Art Conventionally, a plurality of signal recording media are housed,
A signal reproducing apparatus for selecting and reproducing one of the signal recording media has been proposed. The signal reproducing device accommodates a plurality of signal recording media, thereby facilitating the storage and editing of the signal recording media.

For example, as the signal reproducing apparatus, there is a disk reproducing apparatus for reproducing an optical disk on which a music signal is recorded.

[0004] The disc reproducing apparatus has a disc storage section for storing a plurality of optical discs. For example, some disk storage units are capable of storing 100 optical disks.

The above-mentioned disc reproducing apparatus has a function of exchanging an optical disc stored in a disc storage section, that is, a so-called disc changer. The disc reproducing device can continuously reproduce a plurality of signal recording media by using the disc changer. For example, a disc changer is operated by a program input by a user.

[0006] Continuous reproduction of a plurality of optical disks by the above-mentioned disk reproducing apparatus is often performed, for example, by genre or by singer, and is often reflected in user preference.

Further, some disc reproducing apparatuses have a function of storing disc input information inputted by a user with respect to each optical disc stored in a disc storage section. The user can manage the optical disk stored in the disk storage unit based on the disk input information or the text data recorded on the disk itself.

[0008]

By the way, the disk reproducing apparatus can increase the number of stored optical disks by enlarging the disk storage section. However, if the number of stored optical disks increases, management by the disk reproducing device or management by the user becomes complicated. For example, the user may be wondering at which storage position in the disk storage unit the optical disk is stored.

As described above, the optical disk can be managed on the basis of the disk input information, but for the user, every input is sometimes troublesome.

Further, even when newly storing an optical disk in the disk storage section, finding a place suitable for storage in the disk storage section is a troublesome operation for the user.

When the optical disk is stored in an appropriate storage position, it must be taken out and re-inserted into a suitable storage position, and the operation is troublesome for the user. Furthermore, if the optical discs are stored randomly, when the optical discs are continuously reproduced as described above, the optical discs to be continuously reproduced are often separated from each other. I need it.

Therefore, the present invention has been made in view of the above situation, and is intended to accommodate a plurality of signal recording media, and accommodate a plurality of continuously reproduced signal recording media close to each other. It is an object of the present invention to provide a signal reproducing apparatus and method.

[0013]

And transport position control means for controlling the transport means and transporting the signal recording medium based on the storage position information stored in the storage means. And
The signal reproducing device is configured such that, based on the information on the storage position of the signal recording medium stored in the storage unit by the transport control unit, the storage position near the storage position where the previously reproduced signal recording medium is stored. Then, the information recording medium reproduced this time is stored in the storage position where there is no signal recording medium.

In order to solve the above-mentioned problems, the signal reproducing method according to the present invention has a storage position near the storage position where the previously reproduced signal recording medium is stored, and there is no signal recording medium. The signal recording medium reproduced this time is stored in the storage position.

And the torsion spring 6 attached to the shaft 53
And 2.

The cam 60 is driven to rotate by a motor 61 installed diagonally below the loading position A.

The torsion spring 62 is attached to the support shaft 53 so as to urge the distal ends (portions provided with rollers to be described later) of the first and second arms 54 and 55 in a closing direction. Have been.

The first arm 54 has a drive piece 63 extending upward and curved in the shape of an inverted letter in the direction of the rotary table and in the direction of the corner of the housing 33 at the upper part.
And an operation piece 64 extending from the lower center of the drive piece 63 while bending in an almost L-shape in the direction of the rotary table, and are integrally formed of synthetic resin.

Rotating around the center 53, the rollers 65 and 68 provided at the respective leading end portions come into contact with the outer peripheral surface of the optical disc 200 at the loading position A.

When the cam 60 further rotates clockwise, the distal end portion 65 of the first arm 54 pushes the optical disk 200 up toward the curved surface 49 a of the guide rail 49. At this time, the second arm 55 is also
In accordance with the movement of “0” obliquely upward, it rotates counterclockwise about the common support shaft 53.

When the cam 60 further rotates clockwise, as shown in FIG. 9, the optical disk 200 is smoothly rotated and conveyed along the curved surface 49a of the guide rail 49.

The disc reproducing apparatus 1 conveys a desired optical disc 200 to a place where the reproducing unit 3 is disposed by the loading mechanism 28 configured as described above.

The turntable 71 has, at its center, an insertion portion 73 formed of metal and inserted into the center hole of the optical disc 200 at the mounting position B. Further, the reproducing unit 3 includes a chucking member 74 magnetically attached to the insertion portion 73.

In the reproducing unit 3, the insertion portion 73 of the turntable 71 of the spindle motor is mounted at the mounting position B.
Then, the magnet of the chucking member 74 is attracted to the insertion portion 73 and the optical disk 200 is sandwiched. That is, in the reproducing unit 3, the optical disc 200 is in a state of being clamped vertically.

In this clamped state, the optical disk 200 is not supported by the distal end portions (rollers 65 and 68) of the first and second arms 54 and 55 in the loading mechanism 28.

At the time of reproduction, the disk reproducing apparatus 1 supplies a driving current to the spindle motor of the reproducing unit 3 to
The optical disc 200 is driven to rotate in one direction, and in this state,
The pit information recorded on the optical disk 200 is read by moving the optical pickup 72 in the radial direction of the optical disk 200.

When the reproduction of the pit information from the optical disc 200 is completed and the optical disc 200 is returned to the original storage position, the disc reproducing apparatus 1 again operates the first and second transport mechanisms 50 in the loading mechanism 28. Of the arms 54 and 55 (rollers 65 and 6)
At 8), the outer peripheral portion of the optical disc 200 at the mounting position B is supported at two points, and the cam 60 is rotated in the reverse direction (counterclockwise in the drawing) by the motor 61. As a result, the disc reproducing apparatus 1 moves the outer peripheral portion of the optical disc 200 to the first and second optical discs.
2 at the tip portions 65 and 68 of the arms 54 and 55
It is possible to return to the original position (in the slit 21 at the loading position A) while supporting the point.

Next, the rotational position detecting mechanism 29 will be described.

As shown in FIG. 5, the rotation position detecting mechanism 29 includes a rotation detector 81 fixed to the lower surface of a cylindrical support member 35 provided below the rotary table 18.
And a light detection unit 82 installed corresponding to the loading position A (shown in FIG. 6).

The rotation detecting body 81 is provided at first and second concentric positions of the support member 35 having different diameters.
Are formed by the ring-shaped detection plates 81a and 81b.

The first detection plate 81a has a diameter larger than that of the second detection plate 81b, and is formed at its lower end surface with irregularities arranged at a constant pitch in the circumferential direction. That is, irregularities are formed at a pitch corresponding to the 100 slits 21 formed on the rotary table 18.

On the other hand, the second detection plate 81b is located inward of the first detection plate 81a, and its lower end surface is formed with irregularities arranged at different pitches in the circumferential direction.

The light detecting section 82 includes three light sensors (first, second and third light sensors). Each optical sensor is constituted by a set of a light emitting element and a light receiving element.
Are provided at predetermined intervals, and a third optical sensor is provided for the second detection plate 81b. These optical sensors correspond to the corresponding detection plates 81a and 81a.
It is set to output a high-level detection signal when detecting the convex portion of b.

For example, as shown in FIG. 11, the light detecting section 82 performs the following operations for disc numbers “1” to “32”.
The first sensor and the second sensor are the first detection plate 81
The signal waveform S1 and the signal waveform S2 according to a are obtained, and the third sensor obtains the signal waveform S2 by the second detection plate 81b.

In the disk reproducing apparatus 1, the controller 17 controls the rotation of the rotary transport mechanism 29 as appropriate based on the detection result from the light detection section 82 input via the detection circuit system 10.

Therefore, when the disc reproducing apparatus 1 conveys the desired optical disc 200 to the reproducing unit 3, the rotary table 18 is rotated by the rotary conveying mechanism 27 while the rotation operation of the rotary table 18 is detected by the rotation position detecting mechanism 29. Rotate. Then, when the disc reproducing apparatus 1 reaches the loading position A, the rotation of the rotary table 18 is stopped, and the loading mechanism 28 causes the optical disc 20 at the loading position A to be stopped.
0 is conveyed to the reproduction unit 3.

The above is the description of the parts constituting the disc reproducing apparatus 1.

In the disk reproducing apparatus 1, when reproducing the optical disk 200 stored in the disk storage section 2, first, the controller 17 operates the rotary transport mechanism 27 of the disk transport mechanism via the drive control circuit 13. That is, the rotary table 18 is rotated.

Then, the disc reproducing apparatus 1 rotates the rotary table 18 until the desired optical disc 200 is located at the loading position A while detecting the rotation direction and the amount of rotation of the rotary table 18 by the detection circuit 14.

The rotation of the rotary table 18 stops,
When the disc reproducing apparatus 1 is located at the loading position A, the optical disc 20 at the loading position A
0 is conveyed to the reproducing unit 3 by the loading mechanism 28. In the reproducing unit 3, the optical disc 200 is clamped, and the information signal is reproduced. After the end of the reproduction, the disc reproducing apparatus 1 stores the optical disc 200 reproduced from the disposition position of the reproducing unit 3 by the loading mechanism 28 into the loading position A, which is the storing position.

The disc reproducing apparatus 1 can continuously reproduce a plurality of optical discs 200 as described above. For example, when the program key 9a is operated by the user and an instruction to continuously reproduce the plurality of optical discs 200 is issued, the disc reproducing apparatus 1 performs the continuous reproduction.

In the continuous reproduction, the operations of transporting to the reproduction unit 3, reproducing, and returning to the loading position A after the reproduction is completed are continuously performed. That is, the rotary transport mechanism 27 and the loading mechanism 28 of the disk transport mechanism 4
Thus, the desired optical disk 200 is transported to the reproducing unit 3 and is reproduced by the reproducing unit 3.
00 is transported to the loading position A.

By the way, the disk reproducing apparatus 1 moves the optical disk 20 to the loading position A during or after the reproduction.
While the controller 17 controls the disk transport mechanism 4 so that the controller 17 controls the disk transport mechanism 4 to store the information on the optical disk 200 reproduced immediately before obtaining the storage position information stored in the post-reproduction storage position storage area 5a in the RAM 5. Closest slit 21
The rotary table is set so that the slit 21 supposed not to store the optical disk 200 obtained based on the storage information stored in the storage position storage area 5b in the RAM 5 is located at the loading position A. 18 is rotated.

Therefore, the currently reproduced optical disk 200 conveyed by the loading mechanism 28 is stored near the previously reproduced optical disk 200.

The disc reproducing apparatus 1 performs the above-described operation for a plurality of reproduced optical discs 200 in continuous reproduction.

Therefore, the disk reproducing apparatus 1 stores the optical disk 200 reproduced this time at the storage position closest to the storage position of the optical disk 200 reproduced last time and at the storage position where the optical disk 200 is not stored. For this reason, after the plurality of optical discs 200 are continuously played, the plurality of optical discs 200 that have been continuously played back are stored so as to be close to each other.

When the user plays back the optical disc 200 of the same genre or singer continuously, for example, the optical discs 200 of the genre or singer are stored collectively in the disk storage unit 2. Thereby, the optical disc 200 can be classified according to the genre or the singer.
Need not be stored in the disk storage section 2 in advance. Also,
The user can also easily manage the optical disc 200. For example, the user does not need to perform a troublesome operation such as finding a suitable storage position.

Further, in the case of continuous reproduction by genre and singer again, the disk reproducing apparatus 1 can promptly select the desired optical disk 200 by the disk transport mechanism 4 and transport it to the reproducing unit 3. Therefore, the disk reproducing device 1 can shorten the access time of the optical disk 200 during continuous reproduction.

Further, as described above, after the optical discs 200 are organized by genre or singer, if the optical discs 200 are continuously played again by the genre or singer, the disc reproducing device 1 will operate the disc transport mechanism. 4, the operation of transporting the optical disk 200 can be minimized, so that power consumption for continuous reproduction can be reduced. Further, by minimizing the disk transport operation by the disk transport mechanism 4, the optical disk 200
Can be reduced by the transfer operation.

The disc reproducing apparatus 1 always detects the storage position of each optical disc 200 stored in the disc storage section 2 by detecting the presence or absence of the optical disc 200 stored in the rotary table 18, for example.
0 is stored. For example, a disc reproducing device 1
When the rotary table 18 is operated to rotate, the presence or absence of the optical disk 200 is always checked by the detecting unit that emits light, and the information is stored in the storage position storage area 5b in the RAM 5. Therefore, even when the optical disk 200 is removed from the disk storage unit 2 by the user, the storage position where the removed optical disk 200 was stored can be handled as information without the optical disk.

The disk reproducing apparatus 1 has a RAM
5 can store text data recorded on each optical disc 200.

According to the signal reproducing apparatus of the present invention, based on the information on the storage position of the signal recording medium stored in the storage means,
By storing the information recording medium reproduced this time by the reproducing means in a storing position near the storing position where the signal recording medium previously reproduced by the reproducing means is stored and in the storing position where no signal recording medium is stored, A plurality of reproduced signal recording media can be stored close to each other.

Therefore, the signal reproducing apparatus is automatically stored for each genre after the end of continuous reproduction for each genre, even if the user does not previously store the signal for each genre.

Further, the signal reproducing apparatus can shorten the access time due to the transport of a disk when continuously reproducing a plurality of signal recording media.

Then, by merely storing the signal recording medium in the signal reproducing apparatus, the user does not need to search for a suitable storage place.

Further, the signal reproducing method according to the present invention is characterized in that the signal reproduced this time is stored in a storage position near the storage position in which the signal recording medium reproduced last time is stored and where no signal recording medium is stored. By accommodating a recording medium, a plurality of signal recording media that have been continuously reproduced can be accommodated close to each other.

Therefore, in the signal reproducing method, for example, even if the user does not previously store the data by genre, the signal is automatically stored by genre after the continuous reproduction of the genre is completed.

Further, according to the signal reproducing method described above, when a plurality of signal recording media are continuously reproduced, the access time due to the transport of the disk can be shortened.

According to the signal reproducing method described above, the user only needs to store the signal recording medium in the apparatus, and the user does not have to search for a suitable storage place.
