Abstract

PURPOSE:To push a cartridge sufficiently to a cartridge loading port while returning an operating pin to a home position without hindrance by pushing a tip side of the cartridge inserted to a receiving frame with movement against a spring force of a slide frame. CONSTITUTION:The driver is divised such that a tip side of a cartridge 1 loaded to a moving cartridge receiving frame 6 is pushed against a force of a spring 12 of a slide frame 11. For example, the slide frame 11 is moved against the spring force to turn a rising position lock member 13 against the energization of the spring to push the tip side of the cartridge by the rising position lock member 13. Thus, in order to remove an operating pin 8a of an operating member 8 from a slot 1b of a tip side of the cartridge 1, even when a force of a turning energizing spring 15 of the rising position lock member 13 is not sufficiently strong, the tip side of the cartridge 1 is pressed by the movement of the slide frame 11 against the force of the spring 12 and the operating pin 8a of the operating member 8 is removed from the slot 1b of the tip side of the cartridge 1. Thus, it is not required to make the force of the spring 12 of the slide frame 11 strong and the loading of the cartridge 1 and the movement of the slide frame 11 against the force of the spring 12 are implemented with a light force.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a drive device for a disk containing a cartridge, such as an optical disk or a magneto-optical disk.

[Conventional technology]

As a drive device for a disk containing a cartridge as described above, there is a cartridge receiving frame that receives the inserted force (=trisody) in a position where it can engage with the disk therein or the drive shaft, and a cartridge receiving frame that is attached to the receiving frame and has a repelling force. The cartridge is ejected by moving to the original position, and after opening the cartridge by moving against the spring force pressed by the tip side of the inserted cartridge, it engages with the groove on the tip side of the cartridge. an actuating member that is stopped from moving to the original position by a spring force by the groove; and a cam portion that moves the receiving frame up and down to a raised position where a cartridge can be taken in and taken out and a lowered position where it is engaged with a disk or a drive shaft. and a slide frame that supports the receiving frame in a lowered position by a cam portion at a position moved by the spring force, and a position that locks the slide frame moved against the spring force from returning. It has a spring bias that tries to rotate, and when pushed by the tip side of the force trigger inserted into the receiving frame, it rotates against the spring bias and is removed from the position where the slide frame is locked. A cartridge-containing disk drive device having a raised position locking member is known. The operation of attaching and detaching the cartridge in this drive device is as follows.

The slide frame that has been moved against the spring force is locked by the raised position locking member, and therefore, with the cartridge receiving frame in the raised position by the cam portion of the slide frame,
The cartridge is inserted into the cartridge receiving frame from the cartridge insertion opening of the device frame. When the cartridge is inserted, its leading edge pushes the operating pin of the operating member and moves diagonally in the direction of the cartridge insertion direction and the direction of the slide, following the guide groove of the tray/jet receiving frame against the spring force. The operating pin pushes one end of the protruding edge of the shutter that protrudes beyond the front edge of the cartridge to open the shutter, and finally engages with the groove on the front edge of the shutter. This engagement prevents the actuation pin of the actuating member from moving to its original position due to the spring force.

Further, at the final stage of cartridge insertion, the tip side pushes the raised position locking member and rotates it against the spring bias so as to remove it from the slide frame locking position.

As a result, the slide frame is moved by the spring force, and the cam portion brings the car 1 rigid receiving large frame to the lowered position. This causes the disc of the cartridge to engage the drive shaft.

This engagement also prevents the actuating member from returning to its original position due to the spring force of the actuating pin. This is the cartridge mounting operation.

To remove the installed cartridge, move the slide frame by pushing it against the spring force. This causes the cam portion or the cartridge receiving frame to rise. The slide frame comes to a position where the locked step portion is locked with the raised position locking member at the final stage of movement against the spring force. Thereupon, the raised position locking member rotates due to the spring bias and engages with the locked stepped portion of the slide frame, thereby preventing the slide frame from returning due to the spring force. This holds the cartridge receiving frame in a raised position and releases the disk from the drive shaft.

Further, when the upward position locking member is rotated as described above, the distal end side of the cartridge is pushed toward the cartridge insertion port. This movement of the cartridge causes the operating pin of the operating member to come out of the groove on the front end of the cartridge. When the disk comes off the drive shaft and the actuating pin of the actuating member comes out of the groove on the front edge of the cartridge, the spring force causes the actuating member to return to its original position by following the actuating pin or guide groove, and at that time, push the tip of the cartridge. , push out the cartridge so that most of it comes out of the cartridge insertion slot of the device frame. All you have to do is pull out the cartridge from the insertion slot. In this way, the cartridge removal operation is also easy.

[Problem to be solved by the invention]

In the conventional cartridge-containing disk drive device as described above, when the cartridge is removed, the raised position locking member, which is rotated by spring bias so as to engage with the locked stepped portion of the slide frame, locks the front end of the cartridge. Because the pushing force is weak, the actuating pin of the actuating member cannot be removed from the groove on the front edge of the cartridge, and as a result, the actuating pin of the actuating member is prevented from returning to its original position due to the spring force, and the cartridge or cartridge There were times when I remained within the acceptance quota. In order to eliminate this problem, increasing the rotation bias of the raised position locking member not only requires a strong force when loading the cartridge to ensure that it is pushed deep into the cartridge receiving frame, but also increases the pressure on the sliding frame of the raised position locking member. The spring force of the slide frame must not be strong because the contact pressure against the cartridge increases and the frictional resistance increases. Therefore, a strong force is required to push the slide frame against the spring force and bring the cartridge receiving frame to the raised position. If this is done using a motor, the motor must have a large output.

The present invention has been made in order to solve the above-mentioned problem, and it is possible to operate the actuating member during the cartridge ejecting operation without increasing the rotation bias of the member at the raised position opening. The pin can be reliably removed from the groove on the front end of the cartridge, and the spring force allows the operating pin of the operating member to return to its original position without any hindrance, thereby ensuring that the cartridge is sufficiently pushed out of the cartridge insertion slot. The purpose of the present invention is to provide a disk drive device containing a cartridge.

[Means to solve the problem]

The present invention provides a cartridge receiving frame that receives an inserted cartridge in a position where a disk therein can engage with a drive shaft, and a cartridge receiving frame that is attached to the receiving frame and moves the cartridge to its original position by a spring force to eject the cartridge. After the cartridge is opened by moving against the spring force pushed by the front end of the cartridge to be inserted, it engages with the groove on the front end of the cartridge and is returned to its original position by the spring force. It has an actuating member whose movement is locked, and a cam portion that moves the receiving frame up and down between a raised position where a cartridge can be taken in and taken out and a lowered position where a disk engages with a drive shaft. a slide frame that supports the receiving frame in the lowered position by a portion; and a spring bias that attempts to rotate the slide frame, which has been moved against a spring force, to a position where it is stopped from returning; In a cartridge-containing disk drive device comprising: a raised position locking member which is pushed by the leading edge of a cartridge inserted into a receiving frame, rotates against the spring bias, and is removed from a position where the slide frame is locked; The above object is achieved by this configuration of a cartridge-containing disk drive device, characterized in that the distal end side of the cartridge inserted into the receiving frame is pushed by the movement of the slide frame against the spring force.

[Function] In other words, in the cartridge-containing disk drive device of the present invention, the front end side of the cartridge inserted in the cartridge receiving frame is pushed by the movement of the slide frame against the spring force. Therefore, even if the rotational biasing spring of the raised position locking member is not strong enough to remove the operating pin of the operating member from the groove on the front edge of the cartridge, it will not move against the spring force of the slide frame. Since the tip of the cartridge is pushed and the operating pin of the actuating member comes out of the groove on the tip of the cartridge, there is no need to strengthen the spring force of the slide frame, and it is easy to resist the insertion of the cartridge and the spring force of the slide frame. This movement can be performed with a light force, and when a motor is used to perform movement against the spring force of the slide frame, the capacity of the motor can be reduced.

〔Example〕

The present invention will be explained below using illustrated examples.

1 and 2 are a plan view with the shutter closed and a plan view with the shank open, showing one example of a cartridge-containing disk used in the drive device of the present invention, and FIGS. 3 and 4.
The figures are a partial plan view and a partial side view showing an example of the drive device of the present invention.

In Fig. 1.2, 1 is the cartridge, la is the leading edge of the cartridge l, 1b is a groove provided on the leading edge la for locking the insertion of the cartridge l, and 2 is a spring that holds the cartridge in the closed state as shown in Figure 1. The shutter is biased (not shown) and is attached to the cartridge L so as to be able to slide into the open state shown in FIG. It is.

In Fig. 3.4, 4 is a device frame, 4a is an insertion opening for inserting the cartridge L shown in Fig. 12 in the upward direction of the arrow, 5 is a fixed frame integral with the device frame 4, and 6 is a cartridge 1 A cartridge receiving frame 8 receives the disk 3 in a position where it can engage with a drive shaft 7a rotated by a motor 7 attached to the fixed frame 5. It is an operating member rotatably attached to the cartridge receiving frame 6, and slidably engages with an operating pin 8a implanted at its tip or a guide i%t6a provided on the cartridge receiving frame 6, and a spring 10 The actuating pin 8a is pulled so as to come to its original position on the insertion port side of the guide groove 6a (the position shown in FIG. 3). 11
is a slide frame, and the straight grooves 11a1 to 11a provided therein are
3 and the guide pier installed in the fixed frame 5 5 al-5a3
It is movable in the left and right direction within the length range of the straight grooves 11al and 11a2, and is biased leftward by a spring 12 hung between it and the fixed frame 5, and The cartridge receiving frame 6, which is engaged with the guide groove 5b, is moved up and down between the raised position shown in the figure, where the cartridge 1 can be taken in and taken out, and the lowered position, where it is engaged with the disk 3 or the drive shaft 7a. . 13 has a lock pin 13a and a release pin 13b, is rotatably supported by a shaft pin 14 implanted in the fixed frame 5, and is rotated counterclockwise in FIG. 3 by a spring 15 applied between it and the fixed frame 5. This is a raised position locking member that is rotationally biased.

The cam portions 11b and 11c of the slide frame 11 and the vertical guide groove 5b of the fixed frame 5 are provided symmetrically on both sides of the width of the cartridge receiving frame 6.

In the state shown in FIGS. 3-4 in which the lock pin 13a of the raised position locking member 13 is engaged with the locked stepped portion lid of the slide frame 11, the slide frame 11 resists the biasing force of the spring 12. The state moved to the right is locked by the raised position locking member 13, and the cam portions 11b and 11c of the slide frame 11 or the cartridge receiving frame 6 are supported in the raised position where the cartridge 1 can only be inserted or removed at the same level as the insertion slot 4a. It is in a state of being In this state, when the cartridge l is pushed into the cartridge receiving frame 6 from the insertion opening 4a, the cartridge l
Push the operating pin 8a of the operating member 8 against the bias of the spring 10 and advance it toward the upper right according to the guide groove 6a in FIG. As a result, the actuating pin 8a pushes the right end of the protruding edge of the gloss 2, which protrudes above the tip side 1a of the cartridge L in FIG. 1, to the left, and opens the gloss 2 as shown in FIG. Then, it falls into the groove lb of the tip side 1a. When the cartridge L is further pushed in, the tip side 1a pushes the release pin 13b of the raised position locking member 13, and the raised position opening member 13 is rotated clockwise in FIG. 3 against the rotational bias of the spring 15. As a result, the lock pin 13a becomes detached from the locked stepped portion lid of the slide frame 11. As a result, the slide frame 11 is moved to the left by the bias of the spring 12 until the right ends of the linear grooves 11al to 11a3 come into contact with the guide pins 5al to 5a3. As a result, the cam portions 11b and llc lower the cartridge receiving frame 6 to a position where it engages with the disk 3 of the cartridge l or the drive shaft 7a. Therefore, drive shaft 7
The disk 3 can be driven by a.

The movement of the slide frame 11 due to the bias of the spring 12 is detected by a sensor 16 such as a micro switch, and the lowering of the cartridge receiving frame 6 that engages with the disk 3 or the drive shaft 7a is detected by a sensor 17 such as a micro switch. Detected in In the illustrated example, the sensor 17 is provided at a position to detect the inserted cartridge l.

In order to take out the cartridge l attached to the drive device as described above, the restoring motor 18 is rotated to rotate the operating gear 19 once through a gear train (not shown). Planted push pin 1
9a to press the pressed part lle of the slide frame 11, or
A push rod is inserted through the push wire hole 4b provided in the front plate of the device frame 4 together with the insertion opening 4a, and the front bent portion 11f of the slide frame 11 is pushed. In addition, 20 is the operating gear 19.
This is an operating cam of a switch (not shown) for rotating and stopping the motor 18.

When the slide frame 11 is pushed by the push pin 19a of the operating gear 19 or the push rod and moves to the right against the bias of the spring 12, the cartridge receiving frame 6 is raised by the cam portions 11b and 11C, and the disk 3 is When it comes off the drive shaft 7a and the locked stepped portion lid of the slide frame 11 exceeds the position of the lock bin 13a of the raised position locking member 13, the raised position locking member 13 is moved counterclockwise in FIG. 3 by the bias of the spring 15. The lock pin 13a or the locked stepped portion li
d.

When the push by the push pin 19a or the push rod is released at that stage, the leftward movement of the slide frame II due to the bias of the spring 12 is prevented by the engagement of the lock pin 13a with the locked step portion 11d. Ru. As a result, the cartridge receiving frame 6 is supported at a raised position at the same level as the insertion slot 4a. Further, by the above-described rotation of the raised position locking member 13 in the counterclockwise direction, the release bottle 13b is released from the distal end side 1a of the cartridge L.
to make the operating bottle 8a of the operating member 8 escape from the groove 1b.

However, the force pushing the release pin 13b or the cartridge l is
The biasing force of the spring 15 may not be sufficient to remove the actuating pin 8a from 1lllb. Therefore, in the illustrated example drive device, the raised position locking member 13 is provided with a protrusion 13c that is pushed by the right end side 11g of the rising part forming the cam part 11c of the slide frame 11, and the slide frame 11 is raised. When the position locking member 13 is pushed to the right until it is rotated counterclockwise, the right end side 11g of the upright portion of the slide frame 11 pushes the protrusion 13c of the raised position locking member 13, thereby raising it. The position locking member 13 is forcibly rotated counterclockwise, and the release pin 13b pushes the front end side 1a of the cartridge l by the rotational force thereof and the rotational force by the spring 15 described above. This ensures that the actuating member 8
The operating pin 8a can be removed.

The actuating pin 8a that has escaped from the groove 1b easily returns to the original position shown in FIG. Discharge to a state where it comes out. Therefore, the cartridge 1 can then be simply removed from the insertion port 4a.

In this drive device as well, the cartridge l is inserted rapidly, the amount of protrusion of the protruding edge of the shutter 2 from the tip side la of the cartridge l is small, and the operating pin 8a
If the cartridge l is thick, when the cartridge l is inserted into the cartridge receiving frame 6, the actuating pin 8a of the actuating member 8 or
The shutter 7 is placed on the front surface of the protruding edge of the cartridge 2, and the shutter 2 is not pushed by the tip side la of the cartridge l.
The shutter 2 may be pressed by the front surface of the protruding edge of the shutter 2, which may prevent the shutter 2 from opening. In that case, when the cartridge 1 is inserted to a position where the disk 3 can engage with the drive shaft 7a, the operating pin 8a is moved by the distance from the bottom of the groove 1b of the cartridge tip side 1a to the front surface of the protruding edge of the nyatta 2. The printer 2 is pushed further in the insertion direction than if it had been opened. Taking this into consideration, the drive device of the illustrated example has the guide groove 6a of the cartridge receiving frame 6 in such a form that an insertion direction groove portion is further connected to the tip of the diagonal groove portion for opening the shutter 2. ing. As a result, even if the Nyatta 2 is not released, the operating pin 8
This prevents the actuating pin 8a from being stopped by the guide groove 6a and receiving a large force, and it is possible to use a small diameter actuating pin 8a.

Then, the inserted cartridge L pushes the release pin 13b of the raised position locking member 13, and the raised position locking member 13 rotates against the bias of the spring 15.
a is removed from the locked stepped portion lid of the slide frame 11, the slide frame 11 is moved by the spring 12, and the cam portion 1
1b and 1e, the cartridge receiving frame 6 is lowered, the shutter 2 hits the drive shaft 7a, and a large force is applied to the drive shaft 7a and the shutter 2. In order to prevent this large force from being applied, the illustrated drive device uses the cam portion 11b on the insertion opening side as a supporting cam portion, and the cam portion IIIC on the insertion back side as an upper and lower sandwiching cam portion. As a result, the cartridge receiving frame 6 can be tilted with the insertion opening side flipped up, thereby preventing a large force from being applied to the drive shaft 7a and the shutter 2.

Furthermore, the sensor 1 indicates that the cartridge receiving frame 6 is tilted.
It is known that the sensor 6 detects the movement of the slide frame 11 by the spring 12, and the sensor 17 does not detect the lowering of the cartridge receiving frame 6 due to the movement of the cartridge. Frame 11
is moved against the bias of the spring 12 so that the raised position locking member 13 locks. Thereby, the cartridge receiving frame 6 is brought to the raised position, and the cartridge 1 is ejected by the actuating member 8 so that most of the cartridge 1 comes out from the insertion opening 4a.

The drive device of the present invention is not limited to the above-mentioned example, and a part of the slide frame moved by the spring bias protrudes outside the device frame.
Even if the slide frame is moved against the spring force by pushing the protruding part, when the operating pin guide groove is pressed in front of the protruding edge of the holder, the cartridge will move from the raised position to the long member. It may also be possible to prevent movement of the actuating pin before it is pressed.

In addition, the drive device in the illustrated example is a drive device for a magneto-optical disk in which a bias magnet 21 is attached to the cartridge receiving frame 6, or the present invention is not limited to this, but a drive device for an optical disk or a magnetic disk. It can also be applied to

The bias magnet 21 is attached to the cartridge receiving frame 6 by swinging the core 22 of the bias magnet 21 on the support arm 23a of the support member 23 which is swingably supported by the upright bent portion 6b of the cartridge receiving frame 6. The core 22 has a positioning member that supports the bias magnet 21 in a position parallel to the upper surface of the cartridge receiving frame 6 and deeper than the upper surface by coming into contact with the upper surface of the cartridge receiving frame 6. Pins 22al, 22a2, and 22b are provided, and a spring 26 applies rotational force to the support member 23 in the direction of lowering the core 22 side, and a spring applied between the core 22 and the support member 23 24, the positioning pin 22b side is lowered, and therefore the positioning pins 22al and 22a2 are raised, and the support arm 2 of the support member 23 is lowered.
This is done by applying a rotational force to come into contact with the lower surface of 3a. Due to this, Hyasmagui;
When the support member 23 is rotated by the spring bias, the positioning pin 22b of the core 22 is first brought into contact with the upper surface of the cartridge receiving frame 6, and the core 22 is further moved against the bias of the spring 24. and positioning pins 22al, 22
Since a2 is brought into contact with the upper surface of the cartridge receiving frame 6,
It is supported at a position that is half a line from the top surface of the cartridge receiving frame 6 and deeper than the top surface. This state is achieved when the cartridge receiving frame 6 is lowered to drive the disk. This makes the effect of the bias magnet 21 on the disk 3 more effective. If this state is realized while the cartridge receiving frame 6 for taking in and taking out the cartridge L is raised, the cartridge L may come into contact with the bias magnet 21 and damage it. A driven arm is extended to the opposite side of the arm 23a, and a driven pin 23b is implanted there, while an L-shaped operating arm 25 is provided in pair with the fixed frame 5,
When the cartridge receiving frame 6 is in the raised position, the driven pin 23b of the support member 23 is pressed by the actuating arm 25,
The support member 23 is rotated in a direction to raise the core 22 against the bias of its spring. by this,
The cartridge 1 is prevented from coming into contact with the bias magnet 21 when the cartridge 1 is attached or removed.

〔Effect of the invention〕

In the cartridge-containing disk drive device of the present invention, the operating pin of the operating member can be reliably removed from the groove on the front end of the cartridge during cartridge ejection operation without strengthening the rotation biasing spring of the raised position locking member. Therefore, the spring force allows the operating pin of the operating member to return to its original position without any hindrance, and the cartridge is thereby sufficiently pushed out of the cartridge insertion opening.
