Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a disk cassette ejection mechanism, and in particular, the ejection operation of the disk cassette is not performed unless the disk cassette is completely removed from the recording/reproducing position. The present invention relates to a disk cassette ejecting mechanism that prevents this from occurring.

(Prior Art) Most floppy disks, which are recording media for information signals, are housed in cassettes, and the cassettes are provided with openings for exposing the disks. Some cassettes are provided with a shutter plate, and the opening is usually closed by the shutter plate.

Therefore, in a disk device using a disk cassette having a shutter plate, the shutter plate is moved to expose the disk from the opening during the process of loading the disk cassette, and the shutter plate is returned to its original position during the process of ejecting the disk cassette. It is configured to allow An example of this is described in Japanese Patent Application Laid-open No. 58-97166, in which a lever for moving the shutter plate of a disk cassette is provided with a spring bias, and when the disk cassette is inserted into a disk device, the lever is moved. The shutter plate is moved while biasing the spring to expose the disk from the opening, and when the disk cassette is ejected, the stored spring force is used to eject the disk cassette.

(Problem to be solved by the invention) According to the conventional disk cassette ejection mechanism, a spring force is constantly applied via a lever to the disk cassette in the recording/playback position, so when the disk cassette is ejected, the disk cassette is ejected. Before the cassette is completely removed from the recording and reproducing position, the disk cassette begins to be ejected by the spring force, and there is a risk that the magnetic head will collide with the disk cassette.

The object of the present invention is to provide a disk cassette ejection mechanism that eliminates the risk of the magnetic head colliding with the disk cassette by ejecting the disk cassette only after the disk cassette is completely removed from the recording/reproducing position. It's about doing.

(Means for Solving the Problems) The disk cassette ejecting mechanism of the present invention includes a holder that holds the disk cassette so that it can be transferred between an insertion/ejection position and a recording/reproduction position, and a holder that is attached to the holder and holds the insertion/ejection mechanism. and a cassette ejecting lever that moves the shutter plate so that the disks in the disk cassette are exposed from the opening when the disk cassette is inserted into the holder in the ejection position. The device is configured to push out the disk cassette after moving to the insertion/ejection position.

(Function) When a disk cassette is inserted into the holder at the insertion/ejection position, the push lever moves the shutter plate so that the disks inside the disk cassette are exposed through the opening of the cassette, and the holder moves the disk cassette to the recording/playback position. Transfer to. When ejecting a disk cassette, the pushing lever pushes out the disk cassette after the holder moves from the recording/reproducing position to the insertion/ejection position.

(Example) Before explaining the disk cassette ejection mechanism of the present invention, an example of a disk cassette used in the present invention will be explained.

In FIG. 7, a disk cassette 1 has a case on the front and back, and a space is formed inside by the case, and a floppy disk is rotatably housed in this space. An opening (not shown) is formed in the center of the back side of the case, and a disk hub provided at the center of the disk is exposed from this opening. When the disk cassette 1 is loaded into the disk device, the disk hub is rotationally driven by the spindle hub on the disk device side, and the disk is rotationally driven within the case.

An opening 2 called a head window is provided near one edge of the case so that the magnetic head of the disk device can come into contact with the disk inside. A shutter plate 3 is provided at the edge of the case on the side where the opening 2 is formed so as to be slidable along this edge in the left-right direction in the drawing. An opening 4 larger than the opening 2 is formed in the shutter plate 3. The shutter plate 3 is urged to slide to the right in the figure by a spring (not shown), and normally slides by the spring biasing force as shown in the figure to close the opening 2 of the case. When it is slid to the left in the figure against the biasing force, the opening 2 of the case and the opening 4 of the shutter plate 3 are aligned, exposing the disk inside the case.

A recess 5 is formed at the end of the case on the side where the shutter plate 3 is attached, and one side of the recess 5 serves as an engagement surface 6 cut perpendicularly from the end surface of the case. The recess 5 and the engagement surface 6 are covered by the shutter plate 3 when the shutter plate 3 is sliding under the force as shown in the figure, but the shutter plate 3 resists the urging force. When the recess 5 and the engaging surface 6 are moved, the recess 5 and the engaging surface 6 are exposed. One of the corners of the case is cut diagonally to reveal disk cassette 1.
A chamfered portion 7 is provided to prevent incorrect insertion.

Next, an embodiment of a disk cassette ejection mechanism using the disk cassette 1 described above will be described.

In FIG. 1, reference numeral 10 denotes a holder into which the disk cassette 1 is inserted. The holder 10 is formed by an upper plate 11, a lower plate 12, and a side plate 13. The holder 10 is provided so as to be able to hold the disk cassette 1 and transport it in a direction perpendicular to the plane of FIG. 1. The case where the holder 10 is on the near side with respect to the paper surface of FIG. 1 is defined as the insertion/ejection position of the disk cassette, and the case where the holder 10 is on the opposite side with respect to the paper surface of FIG. 1 is defined as the recording/reproducing position.
The holder 10 has a cassette insertion opening 14 on the lower side in FIG. 1, so that the disk cassette 1 can be inserted through the insertion opening 14 parallel to the plane of FIG. 1 and upward in the insertion/ejection position. It's getting old.

protrudes from an opening 18 formed in the top plate 11 to the lower side of the top plate 11, and is adapted to come into contact with the end surface of the disk cassette 1 inserted into the holder 10. The lever 16 is the same lever 16 and the top plate 11
The cut-and-raised piece 19 formed on the top plate 11 is normally biased to rotate clockwise in the figure by a spring 20 hung between the cut-and-raised piece 19 formed on the upper surface plate 11, and the above-mentioned urging force is normally applied by the cut-and-raised piece 21 formed on the top plate Rotation is restricted.

The lower side of the holder 10, that is, the holder 1 in the figure
An ejection lever 23 for ejecting the disk cassette 1 is provided on the paper spine side of the holder 10 so as to be able to slide vertically in the figure along the right edge of the holder 10, and an ejection button is provided at the front end of the ejection lever 23. 22 is fixed. One side of the ejection lever 23 forms a bent edge 34 that rises to the side of the side plate 13 of the holder 10. A part of this bent edge 34
As shown in FIG. b, the cam surface 37 is formed obliquely, and a roller 35 provided on the side plate 13 of the holder 10 is mounted on this cam surface 37. As shown in FIG. 8, the roller 35 is movable along a groove 39 formed in a fixed member such as a chassis, and thereby the holder 10 is moved to the disk cassette insertion/ejection position and the recording/playback position as described above. It is now possible to move between locations. The cam surface 37 and the roller 35 are provided at multiple locations on both sides of the holder 10, and when the ejection lever 23 is pushed to the rear (upward in the figure) as shown in FIG. The holder 10 is raised by being pushed up by the cam surface, and the holder 10 is placed at the cassette insertion/ejection position. The ejection lever 23 is biased by a spring (not shown) so as to slide downward in the figure, thus protruding outward, and when the ejection lever 23 moves due to this biasing force, the roller 35 moves to the second position. As shown in FIG. 10b, the holder 10 is lowered along the cam surface 37, so that the holder 10 is placed in the recording/reproducing position. A crank-shaped hole 24 is formed near the far end of the discharge lever 23. In the diagram of the hole 24, the right end surface is the first engaging part 25 and the second engaging part 25.
It consists of an engaging part 26 and a third engaging part 27. Second
The engaging portion 26 is a stepped engaging portion that connects the first engaging portion 25 and the third engaging portion 27 .

Further back than the back end of the ejection lever 23,
A bell-crank-shaped push-out lever 28 is rotatably supported around a shaft 30 in a plane parallel to the plane of the top plate 11 . The pushing lever 28 is biased to rotate counterclockwise in the figure by a spring 31, and in the state shown in FIG. 1, it rotates due to the biasing force,
An engagement pin 29 fixed to the end of one arm of the push-out lever 28 engages with the second engagement portion 26 of the ejection lever 23, thereby preventing the ejection lever 23 from returning to sliding due to the spring biasing force. Push lever 2
An extrusion pin 32 is fixed to the end of the other arm of 8. The push-out pin 32 is located on the insertion path of the disk cassette 1, and is pushed by the end face of the disk cassette 1 at the end of the insertion stroke of the disk cassette 1, so that the push-out lever 28 is rotated clockwise against the spring 31. It's getting old.

In the original position as shown in FIG. 1, the pin 15 of the lever 16 is on the right side of the path of the shutter plate 3 of the disk cassette 1 inserted from the insertion opening 14, but the pin 15 is located at the back of the disk cassette 1. By being pushed by the end surface, the lever 16 is rotated counterclockwise against the spring 20 and moved to the left.

Next, the operation of the above embodiment will be explained. Figure 1,
In the state shown in FIG. 8, when the disk cassette 1 is inserted from the insertion slot 14 in a direction parallel to the plane of the paper, the rear end surface of the disk cassette 1 pushes the pin 15, and the lever 16 rotates counterclockwise against the spring 20. do. This rotation of the lever 16 causes the pin 15 to move to the left with respect to the disk cassette 1, pushing the right end of the shutter plate 3 and moving the shutter plate 3 to the left. When the disk cassette 1 is pushed further, the disk cassette 1 comes into contact with the push-out pin 32 of the push-out lever 28 at the end of the push-in stroke, and the push-out lever 28 is rotated clockwise against the spring 31. At this point, the shutter plate 3 has moved to the leftmost position, the opening 4 is aligned with the opening 2, and the disks in the disk cassette 1 are exposed through the opening 2. The rotation of the push-out lever 28 causes the engagement pin 29 to disengage from the second engagement portion 26 of the ejection lever 23, as shown in FIG. 9a. Therefore,
The ejection lever 23 moves toward the front (downward in the figure) by the biasing force. As the ejection lever 23 moves, the cam surface 3 formed on the bent edge 34
7 moves from the position shown in FIG. 9b to the position shown in FIG. 10b. As a result, the holder 10, which has been in the raised position, is lowered to the recording/reproducing position as shown in FIG.

In the state shown in FIG. 2, the pin 15 of the lever 16 enters the recess 5 of the disk cassette 1, the pin 15 is sandwiched between the engagement surface 6 of the recess 5 and the shutter plate 3, and is returned by the spring biasing force of the shutter plate 3. is blocked by pin 15. In this state, the disk cassette 1 is accurately positioned by the positioning means, and the magnetic head contacts the disk through the openings 4 and 2 to perform recording and reproduction. Further, as the ejection lever 23 moves toward the front side by the spring biasing force, the engagement pin 29 of the push-out lever 28 comes into contact with the first engagement portion 25 of the ejection lever 23 . As a result, the push-out lever 28 is held in a rotated position against the spring 31, and the push-out pin 32 is separated from the disk cassette 1. Therefore, no pressing force due to the elasticity of the spring 31 is applied to the disk cassette 1. Further, since the pin 15 of the lever 16 comes into contact with the engagement surface 6 of the disk cassette 1 and the lever 16 cannot be rotated in the urging direction, the disk cassette 1 is held at the recording/reproducing position.

Disk cassette 1 from the recording/playback position shown in Figure 2.
To return to the state shown in Figure 1 by discharging the
In the state shown in the figure, the ejection button 22 is pressed and the ejection lever 23 is moved to the rear against the urging force. As the ejection lever 23 moves, the cam surface 37 formed on the bent edge 34 pushes up the roller 35 as shown by the arrow in FIG. 9b, raising the holder 10 to the cassette insertion/ejection position. When the holder 10 finishes rising, the engagement pin 2 of the push-out lever 28
The sliding contact position of 9 is shown in Fig. 10 a, Fig. 9 a, Fig. 8 a
As shown in this order, from the first engaging part 25 of the ejection lever 23, beyond the second engaging part 26, to the third engaging part 27.
, and the push-out lever 28 is rotated by the spring 31 by that amount. That is, when the ejection lever 23 is pushed and the holder 10 is raised to the cassette insertion/ejection position, the engagement pin 2 of the ejection lever 28

When the engagement pin 29 of the push-out lever 28 moves from the first engagement portion 25 to the third engagement portion 27 of the ejection lever 23, the push-out lever 28 is rotated counterclockwise by the spring 31, and the push-out lever 28 is rotated counterclockwise by the spring 31. The disk cassette 1 is pushed in the ejection direction, that is, toward the insertion port 14 by the push-out pin 32 . The amount of movement of the disk cassette 1 in the ejecting direction by the push lever 28 is at least sufficient for the pin 15 of the lever 16 to come out of the recess 5 of the disk cassette 1. While being moved in the ejection direction, the pin 15 of the lever 16 moves relatively along the engagement surface 6 of the disk cassette 1, as shown in FIG.
The pin 15 of the lever 16 comes out of the recess 5 of the disk cassette 1. As a result, the pin 15 of the lever 16 is released from being held between the engagement surface 6 of the disk cassette 1 and the shutter plate 3, and from then on, the lever 16 is moved by the biasing force of the spring 20 and the shutter plate 3. The pin 15 of the lever 16 is rotated clockwise by the return force, and the pin 15 of the lever 16 is moved toward the disk cassette 1.
Press the rear end face to eject the disk cassette 1. Since the return force of the shutter plate 3 is also utilized to eject the cassette 1, a weak force from the spring 20 is sufficient.

When the push-in of the eject button 22 is released from the state shown in FIG. By engaging with the matching pin 29, the ejection lever 2
3. The ejection button 22 is prevented from returning, and the ejection lever 23 and the ejection button 22 are held in their original positions in the pushed-in state as shown in FIG.

In this way, in the above embodiment, the push lever 28 pushes out the cassette 1 only when the holder 10 holding the cassette 1 is moved from the recording/playback position to the insertion/ejection position, and only after the push lever 28 pushes out the cassette 1 to a certain extent. Lever 16
is designed to push out cassette 1,
Unlike conventional disk cassette ejection mechanisms, the cassette is not ejected before the cassette is completely removed from the recording/playback position.
The inconvenience of the magnetic head colliding with the ejected cassette is eliminated.

In the embodiment described above, the first engagement part 25, second engagement part 26, and third engagement part 27 are formed on one side of the hole 24, but in the embodiment described above, the width of the ejection lever 23 is larger than a certain level. Hole 2
4, in short, the first engaging portion 2
5. It is sufficient to have the second engaging portion 26 and the third engaging portion 27, and it is not necessary to form the hole 24.

Next, another embodiment of the present invention will be described.

In FIG. 4, reference numeral 40 is a holder, and 41 is an upper plate thereof. The cassette 1 can be inserted into the holder 40 through a predetermined cassette insertion opening. The holder 40 is supported so as to be movable in the front-rear direction, that is, in the vertical direction in FIG. 4, and is urged downward in the near side, that is, in FIG. 4. Further, the holder 40 is
It has rollers 70 on the sides. A cassette push lever 42 is supported on the top plate 41 so as to be rotatable about a shaft 43 in a plane parallel to the top plate 41. A locking lever 44 is also supported on the top plate 41 so as to be rotatable about a shaft 45 in a plane parallel to the top plate 41 so as to partially overlap the push-out lever 42 . A push-out portion 47 having a contact portion 46 with the end surface of the cassette 1 is integrally formed at the free end of the push-out lever 42 , and this push-out portion 47 extends from the opening 52 formed in the top plate 41 It protrudes from the back side. A spring locking protrusion 48 is provided in the center of the push lever 42;
A locking lever 44 and an engaging portion 49 are integrally provided in a protruding manner. The protrusion 48 and the pin 5 on the top plate 41
A spring 51 is applied between the lever 42 and the 4th
In the state shown, the end surface 53 of the opening 52 of the holder 40
By the push-out portion 47 coming into contact with the push-out lever 47, rotation of the push-out lever 42 due to the biasing force is restricted. One end of the locking lever 44 is a bent portion 54 to prevent incorrect insertion of the cassette, and the other end of the locking lever 44 is formed into a fan shape and serves as a push-out lever locking portion 55. Further, an abutment piece 56 is integrally formed on the outer side near the locking part 55. The central winding part of the wire spring 57 is dropped onto the shaft 45 of the locking lever 44, and
One end of the spring 57 is connected to one arm of the locking lever 44,
The other end of the spring 57 is hooked to the pin 50 on the top plate 41, so that the locking lever 44 is biased to rotate clockwise.
By coming into contact with the end face of the notch 58, rotation of the locking lever 44 due to the biasing force is restricted.

When inserting the cassette 1 in the correct orientation from the cassette insertion opening of the holder 40, the bent portion 5 of the locking lever 44 should be placed above the passage of the chamfered portion 7 of the cassette 1.
4 is located. Further, the push-out portion 47 of the push-out lever 42 is pushed by the end face of the cassette 1 inserted into the holder 40, and the push-out lever 42 can rotate clockwise against the spring 51. A contact portion 59 is formed at the rear end of the holder 40, and the holder 4
The insertion limit of cassette 1 relative to 0 is defined. Furthermore, even if the cassette 1 reaches its insertion limit into the holder 40, if the cassette 1 is pushed in further, the holder 40 will also move to the back. When the locking lever 44 moves with the movement of the holder 40 to the back, the contact portion 56 of the locking lever 44 hits the side plate 60 formed on the immovable frame, as shown in FIG. The locking lever 44 is rotated counterclockwise against a spring 57. Further, when the lock lever 44 is rotated counterclockwise while the push lever 42 is rotated as the cassette 1 is inserted,
The push-out lever locking portion 55 of the locking lever 44 comes into contact with the engaging portion 49 of the push-out lever 42 to prevent the locking lever 44 from returning to rotation. As shown in FIGS. 11 to 13, the holder 40 also has a roller 70 on its side that is attached to a side plate 60.
The ejecting lever 66 is movable in the front-rear direction and in the direction perpendicular to the plane of the paper by being guided by a hook-shaped groove 65 formed in the ejecting lever 66, which is similar to the ejecting lever 23 in the embodiment shown in FIGS. 1 to 3. The cam surface 67 controls the position perpendicular to the plane of the paper, and when the holder 40 is raised toward the front of the plane of the paper by operating the ejection lever, it becomes the cassette insertion/ejection position, and the ejection lever is moved. The position where the holder 40 moves in the opposite direction and descends toward the back side of the paper becomes the recording/reproducing position. When the push lever 42 is in its original position as shown in FIG.
is located to the right of the path of the shutter plate 3 of the cassette 1 which is inserted in the correct direction.

Now, as shown in FIG. 4, when the cassette 1 is inserted into the holder 40 in the correct orientation,
The chamfered portion 7 of the cassette 1 hits the bent portion 54 of the locking lever 44, causing the locking lever 44 to rotate counterclockwise against the spring 57, thereby allowing the cassette 1 to be further inserted. do. If the cassette 1 is inserted in the wrong direction, the rear end surface of the cassette 1 will hit the front of the bent portion 54 of the locking lever 44, making it impossible to rotate the locking lever 44, and the locking lever 44 will not be able to rotate further. Cassette 1 cannot be inserted.

When the cassette 1 is further inserted, the shutter plate 3 of the cassette 1 touches the contact portion 46 of the push lever 42.
The push lever 42 advances to the left side and the contact portion 46 of the push lever 42 comes into contact with the rear end surface of the cassette 1. By further inserting the cassette 1, the extrusion section 47
is pushed by the disk cassette 1, and the push lever 42 rotates clockwise against the spring 51. Due to this rotation of the push lever 42, the contact portion 46 moves to the left relative to the cassette 1, and the contact portion 46 moves to the left relative to the cassette 1.
6 pushes the right end of the shutter plate 3 to move the shutter plate 3 to the left, and the disk in the cassette 1 is exposed in a recordable and reproducible state as in the previous embodiment. When the cassette 1 is completely inserted into the holder 40, the rear end surface of the cassette 1 comes into contact with the contact piece 59 of the holder 40. When the cassette 1 is further pushed in, the holder 40 also moves a certain amount relative to the frame as shown in FIG. By moving the holder 40, the roller 7
0 also moves from the position shown in FIG. 11 to the far end of the hook-shaped groove 65 of the side plate 60 as shown in FIG. 12, and the roller 70 is guided by the groove 65 and descends as shown in FIG. 13. Therefore, the holder 40 is lowered to the recording/reproducing position. Further, as the holder 40 moves a certain distance to the back, the locking lever 44 also moves, and its contact portion 56 comes into contact with the inner surface of the side plate 60 of the frame as shown in FIGS. 5 and 12. The locking lever 44 rotates counterclockwise against the spring 57,
The push-out lever locking portion 55 of the locking lever 44 moves to the immediate vicinity of the engaging portion 49 of the push-out lever 42 . When cassette 1 is released, spring 5
However, as shown in FIG.
The second engaging portion 49 contacts the push-out lever locking portion 55 of the locking lever 44, and rotation of the push-out lever 42 by the spring 51 is restricted. At the recording/reproducing position shown in FIG. 6, the position of the cassette 1 is corrected and held by positioning pins. Furthermore, since the rotation of the pushing lever 42 by the spring 51 is regulated by the pushing lever locking portion 55 of the locking lever 44 as described above, the biasing force of the pushing lever 42 by the spring 51 is not applied to the cassette 1. do not have.

To eject the cassette 1 from the recording/reproducing position shown in FIG. 6, the ejection lever 66 is moved against the biasing force by operating an ejection button (not shown). This movement of the ejection lever 66 causes the cam surface 67 shown in FIG. 13 to push up the roller 70 of the holder 40, causing the holder 40 to rise. Together with the holder 40, the locking lever 44 also moves from the position shown by the chain line in FIG. 12 to the position shown by the solid line, with its contact piece 56 slidingly contacting the side plate 60. When the roller 70 is pushed up by the cam surface 67 as described above, it slips out of the vertical groove portion of the hook-shaped groove 65 as shown in FIG. As shown in FIG. 2, the holder 40 is moved forward along the longitudinal groove portion of the groove 65, thereby moving the holder 40 horizontally by a predetermined amount toward the cassette insertion side. Due to the horizontal movement of the holder 40, the abutting piece 56 is moved against the side plate 60.
The locking lever 44 is rotated clockwise by the spring 57, and the pushing lever locking part 55 escapes from the engaging part 49 of the pushing lever 42, and the pushing lever 42 is rotated counterclockwise by the spring 51. Allow movement. As the push-out lever 42 rotates, its push-out portion 47 pushes the rear end of the cassette 1 and pushes the cassette 1 toward the discharge port. As the push-out lever 42 rotates, its contact portion 46 moves to the right in the figure relative to the shutter plate 3 of the cassette 1, and the shutter plate 3 moves to the right due to the biasing force, as shown in FIG. The opening 2 of the cassette 1 is covered as shown in FIG.

As described above, in the above embodiment, the cassette 1 cannot be loaded unless the holder 40 rises vertically and moves horizontally to a certain extent toward the cassette insertion slot.
Since the magnetic head cannot be pushed out, the magnetic head will not collide with the cassette when the cassette is ejected.

(Effects of the invention) According to the invention, the push-out lever for ejecting the disk cassette allows the holder that holds the disk cassette to insert and insert the cassette from the recording/playback position.
The structure is such that the disk cassette cannot be pushed out unless the disk cassette moves to the ejection position, that is, the disk cassette is completely removed from the recording/reproducing position, so there is no possibility that the magnetic head will collide with the disk cassette when the disk cassette is ejected. The inconvenience will be resolved.
