[0003] Reference numeral 20 denotes a disc insertion slot for inserting a disc 30; 21 denotes a first conveyance roller for conveying the disc inserted from the disc insertion port 20 into the disc stocker 19; A second transport roller for transporting the accommodated disc into the disc playback unit 29; a disc insertion sensor 23 for detecting that a disc has been inserted into the disc insertion slot 20; A first transport roller drive motor for driving 21; a second transport roller drive motor 25 for driving the second transport roller 22; a disk stocker rotating roller 26 for rotating the disk stocker 19; Disk stocker rotating low that drives 26 It is over the drive motor. [0004] The disk reproducing unit 29 shown in FIG.
And 37, a spindle motor for rotating the disk, 38, an optical pickup, 39, a disk mounting sensor for detecting that the disk is mounted in the disk reproducing unit 29, and 45, a control circuit (microcomputer) for controlling the entire apparatus. ). In the apparatus shown in FIG. 1, when a user attempts to insert a disk through the disk insertion slot 20 (position A), the disk insertion sensor 23 detects the disk, and the control circuit 45 drives the first transport roller. The motor 24 is started to rotate the first transport roller 21 to move the disk into the disk stocker 19. Thus, the disc is stored in the disc stocker 19 (position B). When storing a plurality of disks, the disk stocker 19 rotates by a predetermined angle in response to the insertion of the disks, and the next empty disk storage moves to the front and receives the disks. When a disc is inserted, the user is notified of the number of the disc storage section in the front of the disc storage sections D1 to D16, and the number of the disc to be inserted is determined. Is stored in the disk storage unit. Therefore, when playing back a disc, the number of the disc storage section in which the desired disc is stored is selected. The disc stored in the disc stocker 19 is moved to the disc reproducing position (position C) by the rotation of the second transport roller 22 at the time of reproduction, and is mounted on the disc reproducing section 29. When reproducing another disk, the control circuit 45 controls the disk stocker rotation motor 26, rotates the disk stocker 19 via the disk stocker rotation roller 26, and transfers the desired disk to the second transport roller 22. Move immediately before (position B). Then, as described above, the second transport roller 2
The disk is moved to the disk reproducing position (position C) by the rotation of the disk 2 and is mounted on the disk reproducing unit 29. [0008] The disk storage portion at the current position B is called a front disk storage portion, and the disk storage portion storing a disk inserted by a user is called a home disk storage portion for the disk. . During reproduction of the disc, a new disc can be inserted and stored in the disc stocker 19, or conversely, the disc can be ejected from the disc stocker 19. In the above-described disk changer device, when a new disk is stored in the disk storage portion of the disk stocker 19, the disk storage portion at the current position B (that is, the front disk If a disk is present in the storage section), it is necessary to rotate the disk stocker 19 to move the empty disk storage section to the position B, so that the user waits while inserting the disk, Also, the disk mounted on the disk reproducing unit 29 is stored in the disk storage unit of the disk stocker 19 (that is, the home disk storage unit).
In this case, it takes a long time to return the disk from the disk reproducing unit 29 to the home disk storage unit of the disk stocker 19, and there are various problems that a considerable waiting time is required until another disk is reproduced. . In order to solve the above problems, the present invention provides an insertion hole for inserting a recording medium from the outside, a recording medium reproducing means for reproducing a recording medium, and a plurality of recording medium reproducing means. A rotary type provided with a plurality of storage portions for storing a recording medium, each of the storage portions being rotatably moved at a plurality of positions including a front position located between the insertion hole portion and the reproducing means; A recording medium comprising: a recording medium storage unit; and a control unit that controls rotation of the rotary recording medium storage unit and control of setting of a home storage unit in which a recording medium located in the recording medium reproduction unit is to be stored. In the selective reproduction apparatus, the control unit detects whether another recording medium is present in the recording medium reproduction unit when one recording medium is inserted from the outside, and the other recording medium is present. If Detecting whether the storage unit (front storage unit) located at the front position is a storage unit (home storage unit) set as a position where the other recording medium is to be stored, If the front storage unit is the home storage unit for the other recording medium, a search is made for an empty storage unit from among the plurality of storage units excluding the front storage unit. After changing the home storage unit of another recording medium to the storage unit detected by the search,
It is another object of the present invention to provide a recording medium selecting / reproducing apparatus which transports the one recording medium to a front storage section. An embodiment of the present invention will be described below in detail with reference to the drawings. Since the basic configuration of the device is the same as that of the conventional device, a detailed description thereof will be omitted. In the present invention, mainly by improving the control program of the control circuit 45 (microcomputer),
This is to solve the above problems. FIGS. 2 and 3 are flowcharts showing the operation of the disc changer device of the present invention. First, in FIG. 2, when a certain period of time has passed since the end of various operation commands by the user or the end of various operations such as rotation of the stocker and mounting of a disk on the disk reproducing unit 29 (S1). The control circuit 45 checks whether or not a disk is mounted on the disk reproducing unit 29 (S2). If the disk is mounted on the disk reproducing unit 29, the control circuit 45 determines whether the disk currently mounted on the disk reproducing unit 29 The home disk storage unit to be returned is moved to the position B, and the disk is ejected from the disk reproducing unit 29 or a new disk is inserted by the user (S3). On the other hand, in step (S2), when no disk is loaded in the disk reproducing section 29, the control circuit 45 uses the internal memory (not shown) to minimize the rotation angle of the disk stocker 19. A search is made for a vacant disk storage section which is useful, and the vacant disk storage section searched by rotating the disk stocker 19 is used as a front disk storage section, that is, moved to position B (S4). As described above, by moving the empty disk storage unit to the position B and holding it, the disk in the disk reproduction unit 29 can be quickly moved to the disk storage unit and almost no waiting time can be obtained. The user can insert a new disc. Next, in FIG. 3, when a new disk is inserted by the user, the control circuit 45 checks the presence or absence of a disk in the disk storage section (front disk storage section) at the position B (S5). If the disc is not in the front disc storage section, the control circuit 45 checks whether or not the disc is loaded in the disc reproduction section 29 arranged at the center of the disc stocker 19 (S6). 29, the next step (S
Proceed to 7). On the other hand, if the disc is not loaded in the disc reproducing section 29, the process proceeds to step (S10) to convey the disc inserted by the user into the front disc storage section at the position B. In the step (S6), if the disk is mounted on the disk reproducing unit 29, the control circuit 45 determines that the front disk storage unit at the current position B is the home of the disk mounted on the disk reproducing unit 29. It is confirmed whether or not it is a disk storage section (S7). If it is a home disk storage section, the process proceeds to the next step (S8). On the other hand, if the front disk storage section at the current position B is not the home disk storage section of the disk mounted on the disk playback section 29, the step (S
Proceeding to 10), the disc inserted by the user is transported into the front disc storage portion at the position B. In step (S7), if the front disk storage unit at the current position B is the home disk storage unit, an empty disk storage unit in the disk stocker 19 is searched using the memory in the control circuit 45. (S8) If a disk is stored in all the disk storage units, a message indicating that the disk cannot be stored any more is displayed, and the process ends. On the other hand, if there is an empty disk storage section on the disk stocker 19, the empty disk storage section detected in the step (S8) is changed to a home disk storage section (S9) and used. The disc inserted by the user is transported into the front disc storage unit at the position B (S10). As described above, the user can quickly insert a new disk, and even if the disk in the disk playback unit is returned to the disk stocker and another disk is played, the operation of replacing the disk can be performed in a short time. Done. With the above processing, the home disk storage part of the disk is changed, and the disk storage part physically different from the disk storage part when the user first inserts the disk becomes the home disk storage part. If you tell the user that the storage location of the disk has changed, there will be no confusion. Alternatively, label information (disc title, artist name, music category, etc.) is added to the stored disc, and the label information is linked to disc storage section information (disc storage section number). If the device is stored in a memory in the device and the user selects the disk mainly based on the label information, the memory is stored when the home disk storage unit is changed as described above. It is only necessary to update the link between the label information and the disk storage section information, and the user can use the disk without worrying about the number of the disk storage section in which the desired disk is stored. Further, in this embodiment, the disc changer device for a disc has been described. However, the present invention is not limited to this, and a cassette tape changer device, an MD (mini disc) changer device, and a DVD (digital video It goes without saying that the present invention can be applied to various recording medium changer devices such as a disc) changer device. As described above, according to the present invention, when the recording medium is inserted through the insertion hole, the home storage unit is positioned at the front position. It is detected whether or not the home storage unit is changed to an empty storage unit other than the front position when the home storage unit is located at the front position, so that the user does not have to wait, The recording medium can be quickly inserted.
