Description

[Detailed Description of the Invention] The present invention relates to a magazine loading mechanism in a disk changer device, and in particular, it has a plurality of trays for holding disks in the magazine and is capable of locking each tray in the magazine. The present invention is suitable for use in a disk changer device that uses a magazine of this type.

Generally, as mentioned above, a magazine is configured to house a tray that holds disks within the magazine, and to lock the storage state.
When the magazine is removed from the disk changer device, the disk is not exposed to the outside, which is highly effective in protecting it from dust and scratches. However, when such a magazine is used, a means to release the lock is required on the disk changer device side, and usually the loading mechanism that loads the magazine inserted from the magazine insertion slot to the magazine mounting position is required. In addition, a detection means for detecting that the magazine has been brought to the magazine mounting position and stopping the loading operation, and a means for unlocking the magazine tray that has been brought to the magazine mounting position are all provided independently. Because of this, their configurations tend to be complicated, and the electric circuits used to control them tend to be large-scale.

In addition, with a device in which the loading mechanism, magazine mounting position detection means, and magazine lock release are performed separately, an accident may occur with the magazine, or another magazine may be inserted incorrectly, causing the magazine to be brought to the magazine mounting position. If this is not possible, the loading mechanism continues to operate without detecting the attachment of the magazine, resulting in a malfunction.

The present invention was developed to eliminate the above-mentioned drawbacks, and includes a loading mechanism that transports the magazine inserted from the magazine insertion slot to the magazine loading position, and a lock release lever for unlocking the magazine tray. At the same time, the operation of the lock release lever operates a switch means for controlling the loading mechanism, and when the magazine is brought to the magazine mounting position by the loading mechanism, the lock release lever is activated. The loading mechanism is operated to stop the loading mechanism upon detecting that the magazine tray is unlocked, and to continuously operate the loading mechanism when the tray cannot be unlocked and the lock release lever is not operated. A new disk changer device that operates and immediately ejects the magazine, has a simplified configuration, and can quickly and reliably remove the magazine in the event of an abnormal situation where the magazine is not transferred to the magazine mounting position. It provides:

The pins 19b of the cam disc 19 are aligned in a straight line, that is, the rotating arm 16 is moved to the rearmost position, but the stroke of the actuating plate 9 is set slightly smaller than the stroke of the rotating arm 16. As is clear from FIG. 6, after the actuating plate 9 reaches the rearmost position, the spring S
4, only the lever 18 moves within the range of its elongated hole 18a, and the engaging pin 16a of the rotating arm 16 constantly presses the actuating plate 9 with the elasticity of the spring S4. It is possible to prevent the plate 9 from rattling and to always accurately position the magazine M at the magazine device position.

Also, regarding the lever 21, the engagement pin 21c is connected to the small diameter portion 19 of the cam 191 of the cam disc 19.
1b, the lever 21 moves to the left by the elasticity of the spring S5, and rotates the lock release lever 23 counterclockwise. Therefore, the pressing piece 2
3a passes through the hole 4k in the side plate 4b of the chassis 4 and presses the lock release push button Lf on the side of the magazine M.
Each tray in the magazine M can be unlocked.

Further, when the switch SW ₂ is moved to the pin 25 by the left movement of the lever 21 and the operator AC ₂ is pressed, the switches SW _2-1 and SW _2-2 are moved as shown in FIG.
The movable contacts Z ₁ and Z ₂ are switched to fixed contacts Y ₁ and Y ₂ , and the motor 34 is switched to rotate in the opposite direction to that during loading. Then, move the operating lever 27 to the position set by the preset circuit PR.
Without preset circuit PR and potentiometer
If the output voltages of PO are different, the comparator circuit CM
output becomes high level, the switch SW ₃ is closed, the motor 34 rotates the gear 36 counterclockwise, that is, the cam disk 29 counterclockwise, and the cam 29 rotates counterclockwise.
1 to change the height of the operating lever 27, and when the output voltage of the potentiometer PO becomes equal to the output voltage of the preset circuit PR, the output of the comparator circuit CM becomes a low level, the switch SW ₃ is opened, and the motor 34 is turned on. Stop.

On the other hand, in the above-described operation, when the magazine M is brought to the magazine device position, if the magazine is inserted incorrectly and the lock release push button Lf is not located at the position facing the pressing piece 23a of the lock release lever 23. In this case, the lock release lever 23 is held with its pressing piece 23a pressed against the side surface of the magazine M by the spring S5, so that no unreasonable force is applied to the cam disc 19, the lever 21, and the magazine M, and the lever 21 switch by not moving
SW ₂ is not operated, and the motor 34 continues to rotate without reversing its polarity, and proceeds to the eject operation described below. The details will be described later.

When the magazine M has been brought to the magazine mounting section, a control mechanism (not shown) moves the sliding lever 28 forward, that is, downward as seen in the figure, thereby turning the operating lever 27 counterclockwise. By rotating, the opposing tray can be taken out of the magazine M using the arm portion 27a and transferred to a disk playing section (not shown).

Next, the case where the magazine M is taken out from the disk changer device after the performance is finished will be described.

By rotating the operating lever 27 clockwise by a control mechanism (not shown), the tray that has been taken out to the outside of the magazine can be stored outside the magazine M again.

Next, by manually turning on switch SW ₄ for a short period of time, power is supplied to the motor 34 with the same polarity as when the magazine is installed, rotating the gear 36 clockwise and driving the gear 37 to the cam disk 19. It swings and rotates the cam disk 19 clockwise.

When the cam disk 19 starts rotating, the pin 21c of the lever 21 immediately engages the small diameter portion 191 of the cam 191.
b to the large diameter portion 191a, and the lever 21 slides to the right.

Therefore, the switch SW ₂ is released from being pressed by the pin _{25 of} its _operator AC ₂ , _and in _FIG . ₂ , and then switch SW ₄
Even if you remove your hand from the motor 34, the power to the motor 34 is maintained.

Further, as the lever 21 moves to the right, the lock release lever 23 rotates counterclockwise, and its pressing piece 23a is separated from the lock release push button Lf of the magazine M, and each tray is released again. The position within the magazine M is locked by the lock lever L. On the other hand, due to the rotation of the cam disk 19, the rotating arm 16 gradually starts rotating clockwise, and along with this, the actuating plate 9 and the retracting plate 6 also move toward the front, that is, the magazine insertion port 3, via the spring S3. When the pin 12 comes into contact with the rear surface of the magazine M, it temporarily stops, and when the rotating arm 16 presses the rear surface of the magazine M, it starts moving again.

Then, the engagement step 9g is engaged with the engagement arm 13a of the locking lever 13 and is locked, and from then on, only the rotating arm 16 continues to rotate against the spring S3, and the pin 16a , the rear surface of the magazine M is pressed and transferred to the magazine insertion port 3.

Then, as shown in FIG. 7, the rotating arm 16
The engaging pin 16a of the engaging arm 13 of the locking lever 13
b and rotates it clockwise, the engaging arm 13a is connected to the engaging stepped portion 9g of the actuating plate 9.
The actuating plate 9 is released from its lock and moves together with the retracting plate 6 to the magazine insertion port 3 side to the forwardmost position. Therefore, the front shaft 7 of the retracting plate 6 is aligned with the guide grooves 41i, 41j of the chassis 4.
The engaging pawl 6 on the leading edge moves into the inclined extension of the
Both a and 6b are housed below the chassis 4, so that they do not interfere with the movement of the magazine M.

Further, when the actuating plate 9 is released from the locking lever 13 and moves to the forwardmost position, the operating piece 1
As can be seen from FIG. 7, the engaging arm _11a of the rotary arm 16 moves away from the engaging arm 11b, and as _a result, The operating piece 11 rotates counterclockwise and is located at a position separated from the operating element AC ₁ of the switch SW ₁ , and does not collide with the side surface of the operating element AC ₁ of the switch SW ₁ .

As shown in FIG. 8, when the rotating arm 16 is rotated to its forwardmost position, that is, to the front end of the arcuate hole 4g, the magazine M is moved outward from the magazine insertion port 3 by its engagement pin 16a. It protrudes by approximately 1/2 and can be easily taken out.

As the cam disk 19 continues to rotate further, the rotating arm 16 is rotated clockwise again, and its engagement pin 16a leaves the rear surface of the magazine M and moves rearward within the long hole 9d of the operating plate 9. Engagement arm 1 of operation piece 11
By pressing 1b, it is rotated clockwise, and the engaging arm 11a is pressed against the operator AC ₁ of the switch SW ₁ . That is, as shown in FIG. 10, the switch _SW1 is opened and the motor 34 is stopped.

As a result, the magazine is returned to the non-mounted state shown in FIG. 5 again.

The above describes the operation of attaching and detaching the magazine in the disk changer device of the present invention.
Next, when the magazine is damaged and the lock release button Lf cannot be pressed, or even though the operating plate 9 has been brought to the magazine mounting position, the magazine is not moved to the magazine mounting position due to an accident such as damage to the magazine. The following describes a case where another magazine with a similar shape is inserted by mistake.

That is, the loading mechanism starts operating and the actuating plate 9 is brought to the rearmost position, and as shown in FIG. The lock release button Lf is moved to the left by the spring S5 and operated to press the lock release button Lf, but the lock release button is located at a position facing the pressing piece 23a of the magazine lock release lever 23 Since there is no Lf and it cannot be pressed, the lock release lever 23
is held with its pressing piece 23a pressed against the side surface of the magazine.

Therefore, the lever 21 cannot be moved to the left, and the switch
As shown in Fig. 10, the pressing piece AC ₂ of SW ₂ is not operated, and the movable contacts Z ₁ and Z ₂ of the switches SW _2-1 and SW _2-2 are connected to the fixed contacts X ₁ and X ₂ . is held as it is, and the motor 34 continues to rotate without stopping at the magazine mounting position.

As a result, as shown in FIGS. 7 and 8,
The magazine is immediately moved to eject operation, and the inserted magazine is immediately ejected to the outside of the disk changer device.
It is possible to prevent accidents such as the tray being incorrectly inserted into the cassette mounting position, operating the tray control mechanism, and damaging other members including the magazine.

The operation for pushing the magazine outward from the cassette mounting position is exactly the same as the magazine eject operation described above, so a description thereof will be omitted.

As described above, according to the disk changer device of the present invention, the loading mechanism that transfers the magazine inserted from the magazine insertion port to the magazine mounting position has a lock release lever for unlocking the magazine tray. At the same time, the operation of the lock release lever operates a switch means for controlling the loading mechanism, and when the magazine is brought to the magazine loading position by the loading mechanism, the lock release lever is activated. The loading mechanism is stopped when it detects that the magazine tray is unlocked and the magazine tray is unlocked, and the magazine tray is unlocked. Lever 1
It can be carried out in one operation, the configuration is simplified, and the lock release lever cannot be operated due to some kind of accident with the magazine or when a similar magazine of another shape is inserted by mistake. Since the loading mechanism is connected and operated without stopping, and the magazine is immediately pushed outward, it is easy to remove the magazine in case something goes wrong with the magazine or another magazine is inserted by mistake. This has the advantage of being able to perform operations extremely quickly.
