Abstract

PROBLEM TO BE SOLVED: To simplify the mechanism and at the same time, open and close a door member at a proper timing by energizing the door member in a closing direction and at the same time, opening the door member and providing a releasing mechanism on a reproduction block side. SOLUTION: When a rotary plate 21 is rotated counterclockwise, the disk auto changer device is displaced in a direction where the engagement between an engagement arm 19 and a protrusion 18 to be engaged is disengaged due to the rotation of the rotary plate 21. Therefore, a door member 15 is displaced to a closing position by the energizing force of a spring 17. An insertion port 1 is formed at the left edge of a front panel 2 and a displacement limit to the left side of a reproducing block 4 is set to the standby position of the reproducing block 4, thus limiting the direction where the reproducing block is displaced at a position away from the standby position to the right side from the standby position. In this case, when the reproducing block 4 is displaced to a position away from the standby position, the engagement arm 19 and the protrusion 18 to be engaged are not engaged, thus preventing the displacement of the reproducing block 4 from being obstructed.

A situation arises where it is not inserted within the playback block.

When the disc is inserted from the insertion port in a state where the positional relationship between the insertion port and the reproduction block is out of alignment, the disc falls into the moving space of the reproduction block in the housing, Not only can the disc not be removed, but the drive of the playback block is also obstructed, making the disc inoperable.

Therefore, in the disc autochanger device in which the reproduction block is movably supported, when the reproduction block comes out of the positional relationship matching the insertion opening, the insertion opening must be closed by the door member. It is desired to simplify the opening / closing mechanism for opening / closing the member and to operate the opening / closing mechanism at a timing in association with the displacement position of the reproduction block.

Further, in the state where the positional relationship between the insertion opening and the reproduction block is out of alignment, a lock mechanism is provided to lock the door member in the closed position in order to prevent the door member from being opened. desired.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 3 is a perspective view showing the outline of the overall construction of the disc autochanger device according to the present invention. First, the overall construction of the disc autochanger device will be outlined with reference to FIG.

The illustrated disc autochanger device is intended for a CD as a disc. Reference numeral 1 is an insertion opening formed in the front panel 2 surface of the housing so that one disk can be inserted therein.

Reference numeral 3 is a stocker for storing a plurality of discs (CDs). The stocker 3 is provided with a plurality of disc storage portions for storing the discs in an upright arrangement in a horizontal row.

Reference numeral 4 is a reproduction block provided with a reproduction mechanism including a turntable 5 for mounting the disk D and an optical pickup 6 for optically reading a signal from the disk D. The reproduction block 4 is arranged between the front panel 2 and the stocker 3, and is guided by the guide rail 7 so as to be movable along the arrangement direction of the disk storage of the stocker 3.

Further, in the reproduction block 4, an insertion hole 8 through which the disk D can be inserted so as to guide the disk D to a reproduction position where reproduction can be performed by a reproduction mechanism on both the facing surface of the insertion opening 1 and the facing surface of the stocker 3. And 9 are provided.

In the disc autochanger device thus constructed, the reproducing block 4 is configured so that the insertion hole 8 is displaced to the standby position at the position opposite to the insertion port 1 of the front panel 2 in the initial setting state and the standby state. When the reproduction block 4 is displaced to the standby position and the disc D is inserted from the insertion port 1, the disc D is inserted into the reproduction block 4 through the insertion hole 8 and the conveying roller on one side is inserted. It is guided to the reproduction position by 10, 11.

The disc D guided to the reproducing position is temporarily stopped at the reproducing position, and then is pressed onto the turntable 5 by a clamping operation, and the conveying rollers 10,
The avoidance operation of 11 separates the conveyance rollers 10 and 11.

The disk D pressed onto the turntable 5 is rotationally driven, and the index information (TOC information) of the lead-in area is quickly read. On the other hand, when the disc D is crimped onto the turntable 5, if the disc D is stored in the stocker 3 according to the instruction, the disc D is not reproduced even if the disc is reproduced. Even when the reproduction block 4 is directly stored in the stocker 3, the reproduction block 4 is driven in parallel with the reading of the index information. In this case, the reproduction block 4 is driven while the position of the disc storage position of the disc D stored in the stocker 3 is detected according to the instruction.

When the detection of the disk storage position is completed, the drive of the reproduction block 4 is stopped at that point. When the driving of the reproduction block 4 is stopped, the TOC information is read, or if the disk reproduction is still being performed, the operation is continued as it is, and when the series of operations according to the instruction is completed, the turntable 5 is placed. The pressure of the disk D is released, and the transport rollers 10 and 11 are pressure-bonded to the disk D again.

After that, the reproduction block 4 is finely positioned at the detected disk storage position, and is locked in that state. Then, next, the disc D in the reproduction block 4 is transported to the stocker 3 side by the transport rollers 10 and 11.

When the conveyance of the disc D to the stocker 3 side is started, the disc D is conveyed to the other side of the conveyance rollers 12, 1.
It is sandwiched between the three and driven, and is conveyed to the outside of the reproduction block 4 through the insertion hole 9.

When the disc D is conveyed to the outside of the reproduction block 4, the disc D is stored in the designated disc storing position of the stocker 3, and when the disc D passes between the conveying rollers 12 and 13, The disc D rolls and is stored in the disc storage position.

The disc D thus inserted into the insertion slot 1 can be stored in the stocker 3 via the reproduction block 4 so as to be stored in the designated disc storage position. On the other hand, the disks D stored in the stocker 3 can be ejected from the insertion opening 1 in reverse via the reproduction block 4.

In this case, first, the position of the designated disc storage position is detected and positioned, and the reproduction block 4 is displaced to the disc storage position of the disc D to be ejected. After that, the disc D to be ejected is lifted from the disc storage position by a take-out lever (not shown) provided on the base plate 14 which is fixed to the play block 4 and displaced integrally with the play block 4, and the take-up lever So that the disk D rolls out from the stocker 3 to the reproduction block 4 side.

Here, since the insertion hole 9 of the reproduction block 4 is opposed to the disk storage position of the disk D rolled out from the stocker 3, the disk D is inserted into the insertion hole 9 described above.
Is inserted into the reproduction block 4 via. Therefore, the disk D is sandwiched between the transport rollers 12 and 13 and is driven toward the reproduction position of the reproduction block 4 in this case.

When the disk D is driven toward the reproducing position, the disk D is switched from being driven by the conveying rollers 12 and 13 to being driven by the conveying roller 11 or the conveying rollers 10 and 11 and being driven to the reproducing position.

When the disc D is driven to the reproduction position,
The drive of the disc D is stopped, and the drive of the reproduction block 4 to the standby position is started while the disc D is displaced to the reproduction position. In this case, the conveying rollers 10 and 11 are kept in close contact with the disc D, and the disc D is held between the conveying rollers 10 and 11 and the inner wall surface of the reproducing block 4 and held in the reproducing block 4.

When the reproduction block 4 is driven to the standby position, the transport rollers 10 and 11 are driven again in the direction to eject the disc D, and the disc D is inserted through the insertion hole 8 into the insertion port 1 of the front panel 2. When the disc D is ejected to the ejection completion position where the center hole of the disc D projects from the front panel 2 surface, the drive by the conveying rollers 10 and 11 is stopped, and the ejection operation of the disc D is completed. To be done.

In the state where the disc D is displaced to the ejection completion position, only the conveying roller 10 is in close contact with the disc D, so that the disc D does not drop and is held in the displacement completed position. To be done.

On the other hand, the disk storage position of the predetermined disk D stored in the stocker 3 can be changed.
In this case, the disc D displaced from the stocker 3 to the reproduction position of the reproduction block 4 is conveyed by the reproduction block 4 to a position corresponding to the disc storage position of the change destination,
Then, the disc D is ejected from the reproduction block 4 and stored in the disc storage position.

Further, the disc D that has been inserted through the insertion opening 1 and reproduced can be ejected from the insertion opening 1 without storing it in the stocker 3. In this case, the disc D inserted from the insertion opening 1 is pulled into the reproduction block 4 and the disc is reproduced by the reproducing mechanism so that the disc D is reproduced. At the same time, the reproduction block 4 is slightly moved from the standby position so that another disk D cannot be inserted from the insertion opening 1. When the reproduction of the disk D is completed, the pressure contact of the disk D onto the turntable 5 is released, the transport rollers 10 and 11 are pressed against the disk D, and the reproduction block 4 is driven to the standby position in parallel. Then, the disc D is ejected from the insertion port 1 by the transport rollers 10 and 11.

By the way, the disc autochanger device having the above-described structure is as shown in the perspective plan view and the transparent front view showing the main portions of FIGS. 1 and 2, respectively.
A cylindrical door member 15 is interposed between the front panel 2 and the reproduction block 4 and supported by the front panel 2.

The side wall of the cylindrical side surface of the door member 15 is ⅓
It is formed only in a part of the extent, and an opening 16 extending in the generatrix direction through which the disc is inserted is formed in the side wall thereof.

The door member 15 is rotatably supported on the front panel 2 in a horizontal direction by rotating shafts 15a and 15b provided on each bottom surface of the cylinder, and the opening 16 is provided in the insertion opening 1 of the front panel 2. 1 can be rotationally displaced between an open position shown in FIG. 1 and a closed position shown in a transparent plan view of FIG. 4 in which a side wall portion where the opening 16 is not formed faces the insertion opening 1. Is made in. The door member 15 is pulled by the spring 17 and is urged to the closed position.

Further, the wall surface around the opening 16 extends to the center of the cylinder, and the disk between the insertion opening 1 and the insertion hole 8 of the reproduction block 4 in the state where the door member 15 is displaced to the open position. A guide is set up.

By the way, an engaged projection 18 is integrally formed on the lower bottom surface of the cylinder of the door member 15, and an engaging arm 19 which engages with the engaged projection 18 is formed on the reproduction block 4.
An opening mechanism 20 including the above is provided on the base plate 14.

The opening mechanism 20 has a rotating plate 21 on which the engaging arm 19 is installed, and the rotating plate 21 rotates when the reproduction block 4 is displaced to the standby position by the operation of the opening mechanism 20. It is configured so as to be rotated clockwise in FIG. 4 about 21a. When the rotating plate 21 is rotated clockwise, the engaging arm 19 is engaged with the engaged projection 18 to cause the door member 1 to move.
5 is driven to the open position against the urging force of the spring 17 as the rotating plate 21 rotates.

That is, when the reproduction block 4 is displaced to the standby position, the opening mechanism 20 and the door member 15 are engaged with each other, and the door member 15 is displaced to the opening position.

Therefore, when the reproduction block 4 is displaced to the standby position, the door member 15 is displaced to the open position so that the opening 16 faces the insertion opening 1 of the front panel 2 and the opening 16 is also reproduced. The disk is inserted into the reproduction block 4 from the insertion port 1 and ejected from the reproduction block 4 to the insertion port 1 by facing the insertion hole 8 of the recording medium 4.

The engagement arm 19 is composed of a spring and has a structure in which an overstroke is absorbed when the reproduction block 4 is displaced to the standby position. On the other hand, when the reproduction block 4 in the standby position is displaced, the opening mechanism 20 is operated and the rotating plate 21 is rotated counterclockwise. When the rotating plate 21 is rotated counterclockwise, the engaging arm 19 and the engaged projection 18 are disengaged in accordance with the rotation of the rotating plate 21. Therefore, the door member 15 is displaced to the closed position by the urging force of the spring 17.

When the counterclockwise rotation of the rotating plate 21 is completed, the engaging arm 19 is completely disengaged from the engaged projection 18, and the door member 15 is at the closed position. Is displaced. Further, when the counterclockwise rotation of the rotating plate 21 is completed, the displacement of the reproduction block 4 is started. in this case,
The opening mechanism 20 holds the state in which the counterclockwise rotation of the rotating plate 21 is completed, and the reproduction block 4 is displaced.

Here, the insertion opening 1 is formed at the left end of the front panel 2, and the displacement limit of the reproduction block 4 to the left is set at the standby position of the reproduction block 4. Therefore, the direction in which the reproduction block 4 is displaced from the standby position is limited to the right side of the standby position. Therefore, when the reproduction block 4 is displaced to the position deviated from the standby position, the engaging arm 19 and the engaged projection 18 is not engaged, which does not hinder the displacement of the regeneration block 4.

Accordingly, as shown in FIG. 5, the door member 15 is displaced to the closed position when the reproduction block 4 is displaced to the position away from the standby position, and the door member 15 causes the front panel 2 to move. The insertion port 1 is closed, and the disc cannot be inserted into the reproduction block 4 from the insertion port 1.

By the way, the door member 15 is configured to be locked at the closed position. 6 and 7 are perspective front views showing a state in which the reproduction block 4 is displaced to the standby position and a state displaced from the standby position, respectively. Next, the lock mechanism of the door member 15 will be described with reference to FIG.

A hole 22 is formed in the lower end of the cylindrical side surface of the door member 15, and a lock member 23 having a claw portion 23 a inserted into the hole 22 is formed in the front panel 2 as a rotating shaft 24.
It is rotatably supported in the direction perpendicular to the direction of rotation of the door member 15.

In the state where the reproduction block 4 is displaced to the position deviated from the standby position, the lock member 23 is urged in the clockwise direction by the spring 25, as shown in FIG.
As shown in, the claw portion 23a is inserted into the hole 22 of the door member 15, and the door member 15 is in a locked state in which the rotation from the closed position is obstructed.

Therefore, even if the door member 15 in the locked state is intentionally opened, the door member 15 is not opened and the disc can be prevented from being forcibly inserted from the insertion opening 1. By the way, the reproduction block 4 is formed with a protrusion 26 that abuts on the lock member 23. When the reproduction block 4 is displaced to the standby position, the projecting piece 26 comes into contact with the upper portion of the lock member 23 before the standby position. In the reproduction block 4, the protrusion 26 is the lock member 2
Since the displacement to the standby position is continued even if the lock member 23 is brought into contact with 3, the lock member 23 is rotated counterclockwise against the biasing force of the spring 25 as the reproduction block 4 is displaced.

When the lock member 23 is rotated counterclockwise, the pawl portion 23a is pulled out from the hole 22 and when the reproduction block 4 is displaced to the standby position, the pawl portion 23a is moved as shown in FIG. Is completely removed from the hole 22.

Therefore, when the reproduction block 4 is displaced to the standby position and the operation of the opening mechanism 20 is started, the door member 15 is unlocked by the lock member 23, and the operation of the opening mechanism 20 is normal. To be done.

When the reproduction block 4 is displaced from the standby position, the lock member 23 is moved along with the displacement of the reproduction block 4.
Since the contact with the protruding piece 26 of the lock member 2 is released, the lock member 2
3 is rotated in the clockwise direction by the urging force of the spring 25, the claw portion 23a is inserted into the hole 22 of the door member 15, and is in a locked state.

[0055]

As described above, according to the present invention, in the disc autochanger device in which the reproducing block is supported so as to be displaceable, when the reproducing block is out of the positional relationship that coincides with the insertion opening of the panel surface of the housing, the insertion is performed. Since the opening is closed by the door member, it is possible to prevent the disc inserted from the insertion opening from falling into the moving space of the reproduction block in the housing. In this case, since the door member is biased in the closing direction, it is sufficient to drive the door member in one direction of the opening direction to open and close the door member. It can be simplified.

Further, an opening mechanism for opening the door member is provided on the reproduction block side, and the opening mechanism is engaged with the door member in a state where the reproduction block is displaced at a position where the insertion hole faces the insertion opening. Since the door member is opened, the opening mechanism is not engaged with the door member in the state where the reproduction block is displaced to a position deviated from the position where the insertion hole faces the insertion opening, and in this state It is possible to surely prevent the opening of the door member and to open and close the door member in good timing according to the displacement position of the reproduction block.

Further, since the door member is formed in a cylindrical shape and an opening is formed on the side surface of the cylinder and the opening is made to face the insertion opening, the door member is opened. It can be simplified, and the mechanism for opening and closing the door member can be simplified.

Further, according to the present invention, since the door member is locked at the closed position by the lock member engaged with the door member, the reproduction block is moved from the position where the insertion opening and the insertion hole face each other. It is possible to prevent the door member from being forcibly opened in a state where it is displaced to the disengaged position, and it is possible to reliably prevent the occurrence of an accident in which the disc falls into the moving space of the playback block in the housing.

Further, the lock member is displaceable between a lock position in which the door member is engaged and a non-lock position in which the door member is disengaged, and the lock member is urged by the urging member. The door member is locked because the reproduction block is biased to the lock position and the reproduction block is displaced to the position where the insertion hole faces the insertion opening so that the reproduction block presses the lock member to the unlocked position. The configuration can be simplified.
