Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to an automatic changer device in which a plurality of recording media on which information such as music is recorded are stored in a storage portion and the recording media to be reproduced can be automatically replaced. In particular, the present invention relates to an automatic changer device suitable for use in a compact disc player.

(B) Conventional Technology Conventionally, there has been known an automatic changer device for a disc player which automatically replaces a disc to be played back.
The autochanger device is convenient because it can continuously play back desired music without changing the disc manually and can play back continuously for a long time.

By the way, there is known a CD player which optically reads out a compact disc (CD) having protrusions called bits corresponding to a digital signal, which is music information, on a signal surface by using an optical pickup. The CD is easy to handle and has a diameter of 12 cm, which is smaller than that of a conventional analog disc (record disc). Therefore, the CD player selectively ejects the disc for exchanging the disc to be reproduced, or a plurality of discs. It is suitable for an auto changer device in which is stored.

An automatic changer device for a CD player is disclosed, for example, in JP-A-60-52950. The automatic changer device of the above-mentioned publication uses a drawer mechanism that holds a disc in a disc storage case, inserts the disc storage case into the disc storage part, and slidably supports a transport mechanism supported in a vertically movable manner. After pulling out the disc storage case from the disc storage part, the transport mechanism is lowered and moved to the player part for playing the disc. That is, since the autochanger device exchanges the disc to be played back by transporting the disc storage case in which the disc is stored, it is possible to replace the disc to be played back without the mechanism for transporting the disc directly contacting the disc. I can. Therefore, there is no danger of damaging the disc when the disc to be played is replaced.

By the way, the autochanger device needs to selectively take out the disc to be reproduced from the disc storage portion and return the reproduced disc to the original storage position of the storage portion. Therefore, the autochanger device is provided with detection means for detecting the respective storage positions of the storage portions. As the detecting means, the disc number of the disc is set in advance according to the storage position of the storage part, and the support for supporting the disc taken out from the storage part and displacing it to the reproduction position for reproduction is detected. Is provided, and the storage position of the storage unit detected by the detector is counted by moving the support from a predetermined position, one end of the storage position of the storage unit in the moving direction of the support. In many cases, the disc number of the disc supported by the support can be detected according to the count value to select a desired disc.

(C) Problems to be Solved by the Invention By the way, in the above-mentioned auto changer device,
For example, when the disc that has been played back is returned to the storage unit and the disc to be played next next is taken out from the storage unit, when the disc that has been played back is returned to the storage unit, the support is already in the current position. Since the number of the storage position of the storage section is detected, the counter is counted up or down every time the storage position of the storage section is detected with reference to the current position of the support. There has been one that detects the storage position of the storage unit in which the disc to be reproduced next is stored. With this type of device, the time required to detect the predetermined position of the storage section is reduced compared to returning the support to the predetermined position once every time the predetermined storage position of the storage section is detected and moving the support from the predetermined position. It can be greatly shortened.

However, since the above-mentioned autochanger device stops the support once when returning the reproduced disc to the predetermined storage position of the storage portion, the support is moved again and the disc to be reproduced next is stored in the storage device. When detecting the storage position of the disc, the storage position of the storage unit that has returned the disc that has been played back may be counted again.Therefore, the storage position of the storage unit in which the disc to be reproduced next is stored may be incorrect. There was something to detect.

That is, in order to detect the storage position of the storage portion, a detector is used to detect the detection target portion provided according to the arrangement of the disks stored in the storage portion. Since one of the detected parts has a range in which the area to be detected by the detector is provided, the detector detects the area when the support moves from an intermediate position other than the initial position to the next detection operation. An erroneous detection has occurred because the detected portion that is the starting point is detected, is not detected, or is not constant.

Particularly, when the disc is placed on the tray and the disc is configured to be stored in the storage portion by using the tray, by providing the detected portion in the tray, the tray is arranged at the storage position, that is, the storage position of the storage portion. In addition, there is no need to adjust the position of each detected part at all, and it is possible to suppress the occurrence of misalignment of the detected storage position with good workability. Since the detection method of the detected portion and the shape of the detected portion are limited depending on the matter, there is a problem in the above-mentioned erroneous detection.

The present invention provides a disc player made in view of the above points.

(D) Means for Solving the Problems The present invention has a structure in which a recording medium is stored in a storage part using a tray on which the recording medium is mounted, and a detected part is provided in the tray. The detected part is detected by displacing a detector together with a support supporting the detected part, and the detected part is detected after the end of the detected part in the moving direction of the support is detected once. The starting point of (1) is counted by the control circuit to detect the position of the support.

(E) Operation In the present invention, the position of the support is detected by counting the start end of the detection target detected once after detecting the end of the detection target in the moving direction of the support by the control circuit. This prevents re-counting of the storage position of the storage unit where the support has been stopped until now when the support starts moving.

The flag for stopping the counting in 3) is detected (step), and when "0" of the flag is detected, the counter is set to the counter (123) of the ascending / descending control means (117) by the step and "1" is added from the current position number. Is subtracted (step), and then the step of comparing the current position number of the support ( 4 ) with the target disk number is carried out again, and when the flag "1" is detected, the step is returned to. In step, if the lower end of the protrusion of the tray (1) or the top plate (19) is not detected, then the upper end of the protrusion of the tray (1) is detected (step), and the protrusion of the tray (1) is detected. If the upper end is detected, the flag is set to "0" in the step, and then the process returns to the step. If the upper end of the protrusion of the tray (1) is not detected, the process directly returns to the step.

On the other hand, if it is detected in step that the tray (1) is not moving upward, the first moving direction detecting means (119) causes the support ( 4 ) to move by the control signal generated from the raising / lowering control means (117). A fourth switch for detecting whether or not the support ( 4 ) is moving downward (step), and detecting that the support ( 4 ) is displaced to the lowermost end when it is detected that the support ( 4 ) is moving downward. It is detected whether (89) is in the ON state (step). Also, in the step and, in the support ( 4 )
When it is detected that the tray is stopped, the horizontal movement control sequence for controlling the horizontal movement of the tray (1) is executed (step), and then the step is returned to.

By the way, in the step, when the ON state of the fourth switch (89) is detected, the execution of this program is terminated, and when the OFF state of the fourth switch (89) is detected, the control circuit (121) The photo sensor (41) detects that the light receiving state has changed from the transmitting state to the blocking state, and the tray
The lower end of the protrusion (17) of (1) or the protrusion (19a) of the top plate (19) is detected (step). When the lower end of the protrusion of the tray (1) or the top plate (19) is detected, the flag is detected next (step). When the flag "1" is detected in the step, the process returns to the step, and when the flag "0" is detected, "1" is added to the current position number of the support ( 4 ) (step), and the flag ""1" is set (step), and then the process returns to the step.

On the other hand, in the step, the tray (1) or the top plate
If the lower edge of the protrusion of (19) is not detected, then move to the tray (1).
The upper end of the protrusion (17) is detected (step). In the step, if the upper end of the protrusion (17) of the tray (1) is not detected, return to the step and the protrusion (1) of the tray (1).
If the upper end of 7) is detected, the flag is set to "0" (step), and then the current position number of the support ( 4 ) is compared with the target disk number (step). If it is detected in the step that the current position number is greater than or equal to the target disk number, "1" is added to the current position number to move the support ( 4 ) upward (step and),
Return to step. On the other hand, if it is detected in the above step that the current position number is smaller than the target disk number, the current position number is left as it is and the support ( 4 ) is moved down (step), and the process returns to the step.

Next, the operation of the autochanger device configured as described above will be described.

Now, assume that a predetermined CD (2) is being reproduced. in this case,
The support ( 4 ) supporting the tray (1) is displaced to the lowermost part as shown by the broken line in FIG. 5, and the CD (2) is clamp plate (8) of the support ( 4 ). Since it is mounted on the turntable (7) by the chucking member (42) and is separated from the tray (1), the CD (2) is rotated by the rotation of the turntable (7). There is. Further, the optical pickup (11) is mounted so as to be movable in a radial direction perpendicular to the signal track of the CD (2) and is arranged so as to move in the notch (1b) of the tray (1), The signal surface of the CD (2) is traced by the optical pickup (11).

When the reproduction of the CD (2) is completed and the turntable (7) is stopped, the motor (44) of the elevating mechanism ( 9 ) starts rotating in the opposite direction of arrow B. When the motor (44) rotates in the direction opposite to the arrow B, the fifth pulley (45) rotates in the direction opposite to the arrow B, and the rotation is transmitted to the sixth pulley (47) via the belt (46). Then, the worm gear (48) formed on the lower surface of the sixth pulley (47) is rotated in the direction opposite to the arrow C. The rotation of the worm gear (48) in the direction opposite to the arrow C is caused by the sixth gear (49).
Shaft (50) to which the sixth gear (49) is fixed
Is transmitted to the 7th and 8th gears (51) and (52) through the gears, and the 7th and 8th gears (51) and (52) are moved in the opposite direction of the arrow D in FIGS. 3 and 4, respectively. Rotate in the opposite direction of arrow E. When the seventh gear (51) rotates in the direction opposite to the arrow D, the first rotating body (53) rotates in the direction opposite to the arrow F with the shaft (90) as a fulcrum, and thus the first rotating body (53). The guide member (5) having the tongue piece (5b) connected to the action point (91) of (1) is urged upward. On the other hand, when the eighth gear (52) rotates in the direction opposite to the arrow E, the second rotating body (54) in FIG. 4 rotates about the shaft (92) in the direction opposite to the arrow G. The connecting member (55) fixed to the two rotating bodies (54) also rotates in the direction opposite to the arrow G about the shaft (92) as a fulcrum, and the tongue piece (93) is applied to the action point (93) of the connecting member (55). The guide member (6) connected to 6b) is urged upward. Therefore, the support ( 4 ) rises. Where the seventh
And the eighth gears (51) and (52) and the first and second rotating bodies (5
The gear parts (53a) and (54b) of 3) and (54) are formed in the same shape, and the guide member (5)
And (6) are adjusting screws (56) which are connected to the second rotating body (54) and the connecting member (5).
By changing the fixing position with 5), the heights of the supports match, so that the support ( 4 ) is held in a horizontal state and rises. Further, since the substrate (39) to which the sliding mechanism ( 3 ) is attached is fixed to the guide member (5), when the support body ( 4 ) rises, the first member is moved according to the support body ( 4 ). The second arm (57) and the second arm (58) are respectively slid and rotated in a predetermined direction, and the sliding mechanism ( 3 ) simultaneously rises while the intersection angle is displaced.

By the way, while the support ( 4 ) and the sliding mechanism ( 3 ) are being raised, the control circuit (121) shown in FIG. 6 detects a storage position where the tray (1) of the storage section ( 18 ) is not stored. However, the storage position is detected by the motor (44) by the lifting mechanism drive circuit (115).
Is rotated at a constant speed, the support ( 4 ) is raised at a constant speed, and an output signal obtained from the photosensor (41) for detecting the tray position is detected at predetermined time intervals. In that case, the detection of the storage position is slightly different between the bottom storage position of the storage part ( 18 ) and the other storage positions, and whether the tray (1) is stored at the bottom storage position. To detect whether or not the support ( 4 ) is located at the bottom, the first time is measured,
This is performed by detecting the light receiving state of the photo sensor (41) when the first time is measured, and when detecting whether or not the tray (1) is stored at a storage position other than the bottom. Measures the second time with reference to the protrusion (17) of the tray (1) stored at the storage position one below, and the photo sensor (41) at the time when the second time is measured. This is performed by detecting the light receiving state. That is, when the tray (1) is stored in all the storage positions of the storage section ( 18 ), the protrusion (17) of the tray (1) and the protrusion (19a) of the top plate (19) are vertically moved. Since they are arranged at a constant interval, when the support ( 4 ) is raised from the lowermost part at a constant speed, the output signal from the photosensor (41) attached to the support ( 4 ) switches at a constant cycle. When the support body ( 4 ) is located at the bottom, the fourth switch (89) is in the closed state, and the fourth switch (89) is opened by raising the support body ( 4 ). Since the state is switched to the state, the presence / absence of the tray (1) at the lowest storage position of the storage section ( 18 ) is determined by the photo when the first time t ₁ has elapsed from the time when the fourth switch (89) was switched. It suffices to detect the light receiving state of the sensor (41). On the other hand, the storage section ( 18 )
Whether there is a tray (1) in the storage position other than the bottom of
The light receiving state of the photo sensor (41) may be detected when the second time t ₂ has elapsed since the light receiving state of the photo sensor (41) was switched from the blocking state to the transmitting state.

As described above, the storage position where the tray (1) of the storage section ( 18 ) is not stored is detected, and the support ( 4 ) and the sliding mechanism ( 3 ) are detected.
When reaches a predetermined height, the rotation of the motor (44) is stopped, and the support ( 4 ) and the sliding mechanism ( 3 ) are stopped. Here, in the photo sensor (41), the tray (1) is stored in the storage portion ( 18 ) just from the position where the guide grooves (5a) and (6a) of the guide members (5) and (6) are formed. Tray in open condition
(1) A protrusion is provided on a top plate (19) which is disposed above the space between them and is higher than the tray (1) stored at the top of the storage portion ( 18 ) by the space. Since it forms (19a), the protrusion (17) of the tray (1) stored at the storage position located one position higher than the storage position where the tray (1) of the storage section ( 18 ) is not stored, or When the predetermined part (the bottom edge in this case) of the protrusion (19a) of the top plate (19) is detected, the motor
The rotation of (44) is stopped. And at this time the support
Since performing position detection of (4) during upward movement, counteract gravity the support (4) and the inertial force of the sliding mechanism (3) is applied to said support (4) and the sliding mechanism (3) Since the support ( 4 ) and the sliding mechanism ( 3 ) are in the predetermined positions, the heights of the guide grooves (5a) and (6a) of the guide members (5) and (6), respectively, are set to the predetermined values. The tray (1) of the storage section ( 18 ) is stopped at a position corresponding to the height of the storage position where the tray (1) is not stored.

When the control circuit (121) detects that the support ( 4 ) and the sliding mechanism ( 3 ) have reached a predetermined height, the drive current from the lifting mechanism drive circuit (115) is stopped and the motor ( Since the rotation of (44) is stopped, the support ( 4 ) and the sliding mechanism ( 3 ) are stopped. Then, after that, the sliding control means (118) is activated, and the motor (2) of the sliding mechanism ( 3 ) is driven by the sliding mechanism drive circuit (116).
(0) is supplied with a predetermined drive current, and the motor (20) drives the arrow H
Start rotation in the direction. When the motor (20) rotates in the direction of the arrow H, the first pulley (21) rotates in the direction of the arrow H, so that the rotation of the first pulley (21) passes through the belt (22) to the second pulley (23).
And the first gear (24) integrally formed on the lower surface of the second pulley (23) is rotated in the direction of arrow I. The rotation of the first gear (24) in the direction of arrow I is transmitted to the fourth gear (27) via the second gear (25) and the third gear (26), and the fourth gear (2)
Rotate 7) in the direction of arrow J. When the fourth gear (27) rotates in the direction of arrow J, the third pulley (28) rotates in the direction of arrow J, so that the rotation is transmitted to the fourth pulley (30) via the belt (29), The fifth gear (31) provided on the lower surface of the fourth pulley (30) is rotated in the arrow K direction. Here, the rack (13) of the tray (1) supported by the support ( 4 ) is
The support member is meshed with the fourth gear (27).
When the second protrusion (82b) of the arm (82) of the lock mechanism ( 75 ) is pressed by the protrusion (87) formed on the guide member (6) of ( 4 ), the arm (82) moves to the first protrusion (82a). ) Is rotated so as to move out of the movement path of the tray (1), the tray (1) slides in the direction of arrow L by the rotation of the fourth gear (27) in the direction of arrow J. When the tray (1) slides in the direction of the arrow L, the tray (1) supports the support pieces (18a) and (1) provided in the storage section ( 18 ).
Since the tray (1) is supported by 8b), the tray (1) is stored at the storage position where the tray of the storage unit ( 18 ) matches the height of the tray (1) and the tray is not stored. As the storage of the tray (1) progresses, the front part of the rack (13) of the tray (1) meshes with the fifth gear (31) before long. Where the fourth gear
(27) and the fifth gear (31) are rotated by the belt (29).
The third and fourth pulleys (2
Since they are connected by 8) and (30) and have the same shape, they rotate in the same direction at the same speed. Therefore, the sliding of the tray (1) in the direction of arrow L continues smoothly. Then, eventually, the storage of the tray (1) in the storage position of the storage section ( 18 ) is completed, but the completion is switched by the second flap (74) rotated by sliding of the tray (1). The control circuit (121) detects the switching state of the second switch (81), and the rotation of the motor (20) is stopped.

By the way, in the above condition, the CD (2) that has been played so far
When exchanging, the open / close switch (not shown) corresponding to the tray (1) on which the CD (2) is placed may be operated.
Then, the rotation of the motor (20) in the arrow H direction is continued, and the tray (1) stored in the predetermined storage position of the storage section ( 18 ) continues to slide in the arrow L direction. The tray (1) has an arrow L
When slid in the direction, the first and second flaps (73) and (74) inserted into the first and second grooves (14) and (15) of the tray (1) according to the sliding. Each protrusion of (73
b) and (74b) are the first and second grooves (14) and (1), respectively.
It comes off from 5), and the sliding of the tray (1) proceeds. Then, the protrusion (74b) is fitted into the third groove (16) to lock the tray (1), and the second flap (74).
Is rotated, the second switch (81) is switched and the rotation of the motor (20) is stopped. At this time, the tray
(1) is a disc attaching / detaching position for attaching / detaching a CD, and since the notch (1b) is protruded to the state of being located in front of the accommodating portion ( 18 ), it is placed in the concave portion (1a) of the tray (1). CD (2) can be exchanged.

On the other hand, after the storage of the tray (1) in the storage position of the storage section ( 18 ) is completed, the CDs placed on the tray (1) stored in another storage position of the storage section ( 18 ) continuously. When reproducing (2), since the data of the disc number of the CD (2) to be reproduced next is given to the control circuit (121), the tray selected based on the height at which it is currently located is selected. The support ( 4 ) and the sliding mechanism ( 3 ) move according to the height of (1), but the height at which the support is currently located is that of the support ( 4 ) and the sliding mechanism ( 3 ). The number of trays (1) stored in the storage unit ( 18 ) by the signal obtained from the photo sensor (41) during the ascent is counted by the counter (123) of the elevating control means (117) and the storage unit ( 18 When the empty storage position in which the tray (1) of () is not stored is detected, the count number counted up to now by the counter (123) is incremented by "1". It can be out.

Next, a detailed description will be given with reference to the flow charts of FIGS. 8 and 9 regarding the case where the target CD (2) to be reproduced next is detected with reference to the height of the current position of the support ( 4 ). To do.

First, the disc number data is read from the reproduction disc number / music number memory (111) or a ROM (not shown) in which data for reproducing the CD in order of the disc number is written (step), and then the tray (1) Even if the lower end of the protrusion (17) or the lower end of the protrusion (19a) of the top plate (19) is detected by the control circuit (121), the flag for stopping the counting of the counter (123) of the lifting control means (117) is "1". Set (step). Then the current position number of the support ( 4 ) and the target C
Since it is compared with the position number of D (2) (step),
If the tray (1) on which the CD (2) to be reproduced next is placed is stored at a higher storage position than the tray (1) previously stored in the storage section ( 18 ), the lifting mechanism drive circuit ( Since the control signal is generated from the lifting control means (117) so that the drive current for moving the support ( 4 ) upwards from 115) is supplied to the lifting mechanism ( 9 ), the support ( 4 ) is lifted. Start (step). When the support ( 4 ) rises, the state input means (114)
Control circuit for switching state of each switch obtained from (121)
To the tray (1) or the top plate depending on the light receiving state of the photo sensor (41) while detecting whether or not the support ( 4 ) is moving upward (step). The lower end of the protrusion (19a) of (19) is detected (step). When the lower end of the protrusion of the tray (1) or the top plate (19) is detected and the flag is detected to be "0" in the step, the counter (123) of the lifting control means (117) is set. "1" is subtracted from the current position number corresponding to the counted value (step). Here, the flag becomes "0" when the upper end of the protrusion (17) of the tray (1) is detected (step and) and the storage part ( 1
Since the disk numbers of the CD (2) placed on the tray (1) housed in ( 8 ) are determined as 1, 2, 3, 4, 5 from the top, the guide member of the support ( 4 ) When the heights of the guide grooves (5a) and (6a) of (5) and (6) respectively match the height of the tray (1) on which the target CD (2) is placed, 1)
Protrusion (17) or top plate of tray (1) located one level above
The lower end of the protrusion (19a) of (19) is detected, and the current position number and the disc number of the target CD (2) match.

By the way, after the upper end of the protrusion (17) of the tray (1) is detected and the flag is set to "0", the lower end of the protrusion (17) of the tray (1) or the protrusion (19a) of the top plate (19) is Only when it is detected, the current position number set in the counter (123) of the ascending / descending control means (117) is counted down. Therefore, the support ( 4 )
Not only when the detection position detected by the photo sensor (41) provided on the tray is the position of the protrusion of the tray (1) or the top plate (19) that has been detected so far, the support ( 4 ) is In this case, even when the support ( 4 ) and the sliding mechanism ( 3 ) are slightly lowered by the weight of the support ( 4 ) and the sliding mechanism ( 3 ) and are lowered from the lower end of the protrusion of the tray (1) or the top plate (19) during the stop. , The upper end of the protrusion of the tray (1) or the top plate (19) is not detected, and the flag is set to "1".
The support is again used to detect the tray (1) on which (2) is placed.
When ( 4 ) rises, the tray (1) or the top plate (1
Even if the detection position of the photo sensor (41) passes the lower end of the protrusion of (9), the count value of the counter (123) of the elevation control means (117) does not change.

Therefore, when the disk number of the elevation control means (117) of the counter (123) shed set current position number and the target CD (2) are matched, the guide member (5) and the support (4) ( 6)
The heights of the respective guide grooves (5a) and (6a) of the tray surely correspond to the height of the tray (1) on which the target CD (2) is placed, and at this time, the support ( 4 ) Rise is stopped. And
The support ( 4 ) of the tray (1) on which the target CD (2) is placed
Although sliding is started to, this time the support (4) is stopped during the upward movement, the inertial force applied to the support (4) acts in a direction to cancel the gravity applied to the support (4) So
The support ( 4 ) is accurately stopped at a predetermined position. Therefore, the tray (1) is smoothly fitted into the respective guide grooves of the guide members of the support (4) (5) and (6) (5a) and (6a), eventually said support (4) Will be fully supported. Then, after that, the support ( 4 ) moves downward until it is displaced to the lowermost end, so that the target CD (2) can be reproduced.

On the other hand, after the storage of the tray (1) in the storage position of the storage section ( 18 ) is completed, the CDs placed on the tray (1) stored in another storage position of the storage section ( 18 ) continuously. In the case of playing back (2), if the tray (1) on which the target CD (2) to be played next is placed at a lower storage position than the tray (1) that was previously stored, move up and down. The current position number set in the counter (123) of the control means (117) and the target CD
By comparing with the disk number of (2), the lifting mechanism drive circuit (11
The drive current that moves the support ( 4 ) downward from (5) is the lifting mechanism.
Since a control signal is generated from the lift control means (117) so as to be supplied to ( 9 ), the support ( 4 ) starts to descend (step). When the support body ( 4 ) is lowered, step 4 and step 4 through step 4
(89) detects whether the support ( 4 ) is displaced to the lowermost end by detecting whether it is in the ON state, and if the support ( 4 ) is not displaced to the lowermost end, the tray (1) Projection (17) or top plate (1
The lower end of the protrusion (19a) of 9) is detected (step). Then, when the lower end of the protrusion of the tray (1) or the top plate (19) is detected, the flag is detected, but the flag detects the upper end of the protrusion (17) of the tray (1), Since it is set to "1" by the step until "0" is set by, the procedure directly returns to the step. Support
When ( 4 ) is moving downward, it returns to the step through the step and / or step, so if the support ( 4 ) is not displaced to the lowermost end, the tray is again returned by the step.
The lower end of the protrusion (17) of (1) is detected. Then, when the upper end of the protrusion (17) of the tray (1) is detected and the flag is set to "0", the counter (123) of the lifting control means (117) is next.
The current position number of the support ( 4 ) represented by the count value of is compared with the disk number of the target CD (2) (step), but the current position number is the disk of the target CD (2). When the number is smaller than the number, the support ( 4 ) continues to move downward, returns to the step again, and then returns to the step, or step and step to step. Then, in steps, the protrusions (17) of the tray (1)
When the lower end of the flag is detected, the flag is detected. At this time, the step has already been executed and the flag is set to "0".
Is set, the count value of the counter (123) is incremented and "1" is added to the current position number.

As described above, eventually, the protrusion (17) of the tray (1) stored at the storage position one above the storage section ( 18 ) above the tray (1) on which the target CD (2) is placed. The lower edge is detected, and the current position number matches the disk number of the target CD (2) by the step, but due to the relationship of step and
( 4 ) is the protrusion of the tray (1) on which the target CD (2) is placed.
Since the downward movement continues until the upper end of (17) is detected,
Height of the guide member (5) and (6) respective guide grooves of (5a) and a height of (6a), i.e. to support the tray (1) of the support (4) portion of said support (4) Up to a position lower than the height of the tray (1) on which the target CD (2) is placed.
( 4 ) descends. Then, when the upper end of the protrusion (17) of the tray (1) on which the target CD (2) is placed is detected, the flag is set to "0" by the step and the current state of the support ( 4 ) is detected. Since the position number of the disc matches the disc number of the target CD (2), the process proceeds to step, and the counter
The count value of (123) is incremented, the current position number is incremented by "1", and the support ( 4 ) starts to move upward (step). Therefore, this time, the step is executed depending on the judgment of the step. Then, in step, the lower end of the protrusion (17) of the tray (1) stored at the storage position one above the storage section ( 18 ) from the tray (1) on which the target CD (2) is placed is detected. , Next, the detection of the flag is performed. At this time, since the flag is set to "0" in step, the process proceeds to step,
The count value of the counter (123) is counted down and the current position is decremented by "1". When it is detected that the current position number coincides with the disc number of the target CD (2) by step and, the process proceeds to step,
The horizontal movement control sequence (1) is executed. Therefore, the raising of the support ( 4 ) is stopped, and the sliding of the tray (1) on which the target CD (2) is placed onto the support ( 4 ) is started. 4) is stopped during the upward movement, the inertial force applied to the support (4) acts in a direction to cancel the gravity applied to the support (4), said support (4) is accurately stopped at a predetermined position To be done. Therefore, the tray (1) is smoothly fitted into the guide grooves (5a) and (6a) of the guide members (5) and (6) of the support body ( 4 ), and eventually the support body ( 4 ).
It becomes fully supported by ( 4 ). Then, after that, the support ( 4 ) moves downward until it is displaced to the lowermost end, so that the target CD (2) can be reproduced.

(G) Effect of the Invention As described above, according to the present invention, the tray on which the recording medium is placed is used to store the recording medium in the storage portion, and the detected portion is provided in the tray. Since the detection part is detected by displacing the detector together with the support body that supports the tray, the position adjustment for aligning each detection part with the storage position of the storage part, that is, the arrangement position of the tray is performed. It is not necessary to improve workability, and it is possible to make it difficult to cause a positional deviation between the detected storage position and the support, and in particular, the autochanger device according to the present invention is configured to detect the detected part. The position of the support is detected by counting the start end of the detected part detected once after detecting the end of the detected part in the moving direction of the support to detect the position of the support. Start moving It was not that storage position of the housing part in which the support has been stopped until now is again counted during reliably has the advantage that the reproduction of the target of the recording medium is possible. At this time, since the control circuit counts the start end of the detected portion detected once after detecting the end of the detected portion in the moving direction of the support to detect the position of the support, There is an advantage that the target recording medium can be surely reproduced without the re-counting of the storage position of the storage unit where the support is stopped when the support starts moving.
