Abstract

PURPOSE:To easily replace housed disks one by one by drawing out one optional tray out of plural housed trays to the playback position of the disk and storing an optional specified address in the case of housing the disk. CONSTITUTION:In the case of replacing the disk which has been played back with one of the disks in the plural housed trays, a stock command and the registration number of a new disk are inputted by operating an operational key 57. When a sensor 56 for detecting the presence or absence of a disk on a tray detects that the above registration number is vacant, the tray on which the new disk is placed and which is at a position where it can be ejected is housed in a vacant tray housing part and the registration number and information inputted by the key are stored. When the registration number is used, that is, the disk is housed, the registration number and the information of the former disk are erased and the tray on which the new disk is placed is housed at the position of the former disk to be registered. The tray on which the former disk is placed is conveyed to the position where it can be ejected.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention stores a plurality of discs of various types, selects and plays a desired stored disc by external operation, and plays the stored discs one by one. can be replaced, and
The present invention relates to a method for controlling a disc autochanger device that allows discs other than the stored disc to be played back in the same way as a normal single player.

[Prior Art] Conventional disc autochanger devices of this type include a so-called jukebox type device in which a plurality of disks are stored in a storage section of the device in advance and one of the disks is played back, and a device in which a predetermined magazine is used. There are known jukebox formats in which multiple discs are stored in a device, and the magazine is loaded into the device to play one of the discs in the magazine.The jukebox format is mainly used for business use and The above magazine format is used for consumer use.

[Problem to be solved by the invention]

However, among the conventional disc autochanger devices mentioned above, the jukebox type only plays the discs that have been stored in advance, and the user can play discs that are not stored or arbitrarily change one disc in the storage compartment. It was difficult to remove the disk from the device and replace it with a new disk.

In addition, with the magazine format, it is not possible to replace just one disc unless the magazine is removed from the device, and in the case of the magazine format, when the magazine is removed, all information such as the playing order of the discs, index, etc. manually entered by the user is lost. The information disappears, and when a new magazine is installed, the above information must be entered again, making the operation cumbersome.

Furthermore, in any of the above cases, the storage locations of the discs in the autochanger device are set permanently, so for example, popular genre discs are stored in the first row, jazz in the second row, classical music in the second row, and classical discs in the second row. is stored in the third row, and if you replace jazz in the second row with classical, the user will have to remember that the second row is classical, and the number of discs stored will be large. Indeed, it is complicated for the user, and as a result, there is a problem in that the operability of the autochanger device becomes poor.

[Object of the Invention] The present invention has been made in view of the above-mentioned points, and it is possible to select and play a desired stored disc by external operation, and to easily replace the stored discs one by one.
In addition, when storing a tray that has been pulled out to the disk loading/unloading position, it is possible to memorize any designated address for the tray regardless of where the tray is stored, improving operability of the disk. The purpose of the present invention is to provide a method for controlling an autochanger device.

[Summary of the invention]

In order to achieve the above object, a method for controlling a disc autochanger device according to the present invention transports a desired tray out of a plurality of stored trays to a playing position and plays the discs on this tray. In an autochanger device for discs, any one of the above trays
The disc is capable of being pulled out to a disc loading/unloading position, and when storing the pulled out tray, any designated address can be stored for the tray regardless of where the tray is stored. It is.

In addition, if the specified address specified when storing a tray is not vacant, the new specified address of the tray to be stored is prioritized and stored, and the tray at the old specified address is transported to a position where it can be ejected. The present invention is characterized in that information regarding the tray that has been conveyed to a possible position is erased, and the tray from which this information has been erased is regarded as an empty tray.

The hook parts 38, 38 of the tray hanger engage with the notches 39, 39 on both side edges of the tray 24 and become integrated with the tray 24, and in this state, the tray hanger 37 and the tray 24
Both sides of the plate are arranged so that they are almost flush with each other. And the integrated tray hanger 37 and 114240
Both side edges are engaged with and guided by grooves 40, 40 formed on the inner surface of the tray base 25.

In addition, a pinion 41 constituting a double speed mechanism, which will be described later, is pivotally supported on the tray base 25 so as to be located in a groove 40 on the left inner surface of the tray base 25, and protrudes from the lower surface of the tray base 25. The lower half of the binion 41 meshes with a rack 42 provided on the upper surface of the sub-chassis 10 and extends in the loading direction, and the upper half of the binion 41 engages with a tray hanger placed on the tray base 25. 37 and a rack 43 formed on the lower surface of the left side edge of the tray 24.

Therefore, the tray base 25, which is horizontally movable on the sub-chassis 10 and on which the tray hanger 37 and the tray 24 are integrally placed, is installed as shown in FIGS. 6 and 7. When the device is pulled out from the opening 44 on the front side to the loading/unloading position, one drive gear 3 of the loading drive unit Mz is pulled out as shown in FIG. 13A.
0a and the rack 35 of the tray base 25 are in mesh with each other.

Here, when the loading drive unit l-M operates, the tray base 2 is rotated by the rotation of the drive gear 30a.

Further, when the tray base 25 passes the ejectable position (playing position),
The tray 24 is placed in the tray holders 5 and 5 as shown in Figure 3C.
When the tray base 25 is moved to the storage position where the
While the tray hanger 37 on the upper surface, the tray 24, and the binion 41 which is pivotally supported by the tray base 25 move by a distance l together with the tray base 25, the rotation movement of the binion 41 by a distance l on the rack 42 causes The tray hanger 37 and the tray 24, which mesh with each other via the binion 41 and the rack 43, are sent out as the binion 41 rotates and move by a distance l.

Therefore, as shown in FIGS. 13B and 13C, when the tray base 25 moves by a distance Ml from the ejectable position (playing position) to the storage position, the integrated tray hanger 37 and the tray 24 move a distance Ml. 21! ,
This double-speed mechanism allows the tray 24 to move by a sufficient amount horizontally. A rotatable stopper 45 is provided on the top surface of the tray hanger 3 as shown in FIG.
When the tray base 25 is pulled out to the loading/unloading position with the tray 7 and the tray 24 placed together, one end surface 45a of the stopper 45 comes into contact with the protrusion 33 of the left guide rail 31 of the subchassis 10. , the stopper 45 is prevented from rotating counterclockwise. This results in
As in a normal disc playback device, when manually pushing the tray base 25 portion at the loading/unloading position into the device, even if only the tray hanger 37 portion is pushed in, the other end surface 45b of the stopper 45 does not rotate. and the tray 24 contact each other, and only the upper tray hanger 37 and the tray 24 are pushed into the device, and the tray base 2
As shown in FIG. 8, the tray hanger 37,
The tray 24 and tray base 25 are now pushed together into the device, ie to the ejectable position (playing position). Furthermore, when the tray base 25 portion is completely pushed to the ejectable position (playing position), as shown in FIG. Notch 46
As a result, the engagement between the one end surface 45a of the stopper 45 and the protrusion 33 is released, and the stopper 45 can now rotate counterclockwise, thereby removing the tray on the tray base 25 at the ejectable position (playing position). The hanger 37 and tray 24 portion can be moved to the storage position.

The playback drive unit M3 plays back the disc placed on the tray 24 in the ejectable position (playing position), and as shown in FIG. 6 and FIG. 10 Tray holder 5 on the bottom surface
A turntable 48, a pink amplifier, various servo systems, etc. are placed on a chassis 47 that is supported with its side as a pivot shaft.

When playing a disc, the entire chassis 47 of the playback drive unit M3 moves upward, and the disc on the tray 24 is lifted from below by the turntable 48, and the clamper unit 49 disposed above the subchassis IO It is held in place and rotated.

Further, the disc played as described above is transferred to the tray storage section constituted by the tray holder 5, as shown in FIGS. 11 and 12, by the above-described loading operation together with the tray 24 on which the disc is placed. It is designed to be stored in 4. As mentioned above, the tray storage section 4 has a storage shelf that can store 11 trays 24, and 10 trays 24 are always stored regardless of the presence or absence of discs, and the remaining one will be described later. As such, the empty tray is placed on the tray base 25 in the ejectable position (playing position) together with the tray hanger 37. Further, as shown in FIGS. 3 and 5, the sub-chassis 1O, which moves up and down with the tray base 25 on which the tray hanger 37 and the tray 24 are placed, is mounted on the lift links 8 and 8 as shown in FIGS. Since it moves in an arcuate trajectory centered on the pivot bins 9, 9, the 10 trays 2 stored in the tray storage section 4 are moved by the loading operation of the tray base 25 described above.
4 are also stacked in a substantially arc shape, as shown in FIG. Therefore, the tray holder 5 constituting the tray storage section 4 has a bulged shape on the front side of the apparatus.

Further, the vertical movement of the sub-chassis 10 is controlled by the above-mentioned elevating mechanism to the ejectable position (see FIG. 1O).
This can be done not only in the playing position) but also in the storage position shown in FIG. When the trays 24 move up and down at the storage position, as shown in FIG. 16, 11 trays 24, including one empty tray,
Each item is stored in a storage shelf, so
Only the tray hanger 37 placed on the tray base 25 moves up and down as the sub-chassis 10 moves up and down, and the notched portions 39, 39... of the housed trays 24, 24...
The hook portion 38 of the hanger moves as it passes through. Then, the tray hanger 37 that has stopped at the predetermined tray 24 position grips and pulls out the predetermined tray 24 from the drawer side, and transports the pulled out tray as an empty tray to the ejectable position (playing position) described above. It is done like this.

Note that this device includes, for example, an optical sensor, and has a subchassis IO in the ejectable position described above (the position where the tray base 25 placed on the subchassis 10 corresponds to the front opening 44 of the device). A position detection sensor (not shown) of the mechanical part that detects whether the disc is placed on the tray, and a disk presence/absence detection sensor (not shown) that detects whether the disc is placed on the tray in the ejectable position. ) are provided, and signals from these sensors are sent to a control circuit to be described later.

Next, a circuit configuration for implementing the method for controlling the disk autochanger device described above will be described with reference to FIG. 18.

The recorded information on the disc is read by an optical pickup 50, and this optical pick amplifier 5
A signal from 0 is converted into an audio signal via a signal processing circuit 51, and this converted signal is amplified by an amplifier 52 and sent to a speaker 53. The signal processing circuit 51 also outputs a play end signal based on the signal from the pickup, and this play end signal is sent to the control circuit 54. This control circuit 54 is constituted by a microcomputer (CPU), and performs operations not shown in the flowcharts of FIGS. 19 and 20 according to a predetermined control program.

The control circuit 54 also includes a mechanism for detecting whether or not the tray base 25 placed on the vertically movable sub-chassis 10 is at a position corresponding to the opening 44 on the front of the apparatus, that is, at a position where it can be ejected. position detection sensor 55,
Signals are input from a disk presence/absence detection sensor 56 that detects whether or not a disk is placed on the tray 24, and an operation key 57 provided on the front of the device. In response to the signal, the control circuit 54 performs the operation described later and outputs a predetermined command signal to the mechanical section drive circuit 58.

By the way, this device described above has 11 trays and 11 storage shelves in the tray storage section, and 10 trays are stored in 10 of these shelves to stock 10 desired discs. The 11th tray is an empty tray, and this empty tray comes out of the device, making it possible to play like a normal single player.

In other words, the operation is exactly the same as a normal single player in that you operate the operation keys on the front of the device, pull out the first tray, place the desired disc on the tray that comes out, and play it. By issuing a stock command to the played disc, the tray carrying the disc is stored in the first stage of the tray storage section, and the second tray is transported to the ejectable position and becomes a standby state. . By repeating this operation, 10 discs can be stored, and only the 11th tray becomes an empty tray that can only be operated in the same way as a normal single player, and cannot be stored in the tray storage section. It looks like this.

Additionally, information regarding the ten stored discs described later can be stored, and the discs can be taken out one by one and replaced with another disc.

Therefore, FIG. 19 shows the disc play operation according to the control method of the present invention when a stock command has been issued to the disc and ten trays 24 carrying discs have already been stored in the tray storage section 4. This will be explained with reference to the flowchart.

In order to play and play a desired disc, first operate the operation keys 57 on the front of the device and enter a play command and a registration number as a designated address stored in advance corresponding to the disc to be played. (Step 1). Then, as described above, the position detection sensor 55 of the mechanical part detects whether or not the tray base 25 placed on the sub-chassis 10 is at a position corresponding to the opening 44 on the front of the apparatus, that is, at a position where ejection is possible. Based on the signal, it is determined whether the empty tray 11100 is in the ejectable position (step 2), and if it is in the ejectable position, the subchassis 10 moves up and down, and the tray base 25 moves horizontally. The empty tray is stored in a storage shelf with only one empty spot in the tray storage section 4 (step 3). Then, in the so-called storage position where the tray base 25 has been moved to the storage section side (in this state, all 11 trays 24 are stored in the tray storage section 4), the sub-chassis 10 is moved to the specified registration with key input. The numbered disc is moved to the tray position, and at that height position, the tray base 25 is activated to pull out the tray carrying the designated disc (step 4), and the performance is performed at that height position (step 4). Step 5). Therefore, in the case of this device, the position where the sub-chassis 10 moves and the tray 24 is pulled out is the performance position, and one position of this performance position is the ejectable position.

When the performance ends and a play end signal is output from the signal processing circuit 51 (step 6), the played tray 24 is stored in the original storage shelf (step 7), and the tray storage section 4 becomes empty. The empty tray stored in the location is moved to the state before the key was applied, that is, the subchassis 10 carrying the empty tray moves to the position where it can be ejected (step 8).
.

Next, a disk storage operation according to the control method of the present invention when several trays 24 carrying disks are stored in the tray storage section 4 will be described with reference to the flowchart of FIG.

If you play a new disc as a single player using the 11100 empty tray in the ejectable position, and you like the new disc, and you want to replace it with one of the discs already stored, first perform the steps above. The stock command and the registration number of the new disk are entered manually using the key 57 (step 1). Then,
Based on the signal from the disk presence/absence detection sensor 56 on the tray, it is determined whether a new disk is placed on the empty tray (step 2), and if a new disk is placed on the empty tray, next It is determined whether the registration number entered manually as the number for the new disc is available by comparing it with the information (Step 3).

If the above registration number is empty, the tray with the new disc placed in the ejectable position will be ejected into the tray storage section 4.
step 4) in which the manually entered registration number and new disc information are stored in the empty space of the disc. Here, the disc information that is stored includes the playing time of the disc, etc.
This is so-called TOC information indicating the contents of the disc. and,
Any tray 24 in the tray storage section that has not yet been assigned a registration number, that is, has no disk placed thereon, is transported as a new empty tray to the above-mentioned ejectable position (step 5).

In addition, if the above registration number is already in use, that is, if a disk with a manually entered registration number is already stored, the information of the old disk with that registration number will be deleted along with the registration number, and the old disk will be replaced. The empty tray 24 now functions as a new empty tray (step 6).

Then, the empty tray on which the new disc is placed and which is in the ejectable position is stored in an empty space in the tray storage section 4, and the manually entered registration number and new disc information are stored preferentially (step 7). Furthermore, the tray 24, which acts as a new empty tray on which the old disk with the old registration number on which all stored information has been erased, is transported to the ejectable position described above as the 11100 empty tray (step 8).

According to the embodiment of the control method of the present invention described above, as shown in FIG. 17, the vertical movement of the sub-chassis 10,
By the combination of horizontal movement of the tray header 25 placed on the sub-chassis 10, it is possible to select and play a desired stored disc, and the stored discs can be easily replaced one by one. .

Then, the user only has to remember what kind of disc is in the specified registration number that he or she has specified.
In other words, if you only memorize the designated registration number and genre, for example, number 1 has a popular genre disc, number 2 has a jazz disc, number 3 has a classic music disc, etc., and you only have to memorize the designated registration number and the genre, you can easily determine what kind of discs those discs are. There is no need to remember whether the item is stored in the storage location. This means that
For example, if you want to replace the jazz disc at address 2 with a classical disc, all you need to do is change its designated registration number from address 2 to address 3. Moreover, this number 3 has been previously memorized as classical by the user. This eliminates the need for the user to re-memorize that a classic disc is stored in the second tier, as was the case in the past. This greatly improves performance.

In addition, if the specified registration number specified when storing a tray is not available, the new specified registration number of the tray to be stored is stored preferentially, and the tray with the old specified registration number is transported to a position where it can be ejected. The information about the tray that has been conveyed to the lever ejectable position is deleted, and
The tray with this information erased is considered an empty tray, so
Discs other than the stored disc can also be played as a normal single player. In addition, until a stored disc is removed from the device, the information about that disc is completely stored, and unlike conventional magazine-type autochangers, multiple discs that have been input each time a disc is replaced. There is no possibility that all of the information will disappear.

Therefore, it can be operated like a single player, and there is one player in the device.
It is possible to store 0 discs, and by simply placing the disc that you want to store on the tray that comes out of the device, you can freely play and store the disc. Furthermore, like a normal autochanger device, it is possible to perform random or continuous play of 10 stored discs, and it is also possible to play only a portion of the discs that you like.

In addition, you can change the discs one by one at any time, except during a performance, and replace the old disc stored in the device with a new one.Also, since it has 11 trays, you can play with several types of discs. It is possible to mix disks.

[Effects of the Invention] As described above, the method for controlling a disc autochanger device according to the present invention transports a desired tray among a plurality of stored trays to a playing position, and plays the disc on this tray. In the disc autochanger device, any one of the trays can be pulled out to the disc loading/unloading position, and when storing the pulled out tray, regardless of the storage location of the tray, Since it is possible to memorize any designated address for the tray, it is possible to select and play a desired stored disc by external operation, and also to easily replace stored discs one by one.This also improves the operability of the autochanger device. Furthermore, if the designated address specified when storing a tray is not available, the new designated address of the tray to be stored is prioritized and stored, and the tray at the old designated address is stored. The information about the tray that has been transported to the ejectable position is erased, and the tray with this information erased is considered an empty tray, so you can use this empty tray to play as if it were a normal single player. Discs other than the stored disc can be played back, and information regarding any stored disc can be completely stored until the disc is removed.
