Abstract

PROBLEM TO BE SOLVED: To provide a door device which provides freeness for opening/closing direction of a door. SOLUTION: After a door 30 in closed state is rotated 90 deg., it slides along a side surface 13 of the device main body 12. Since, the door 30 is positioned along the side surface 13 except for a panel surface 16 of the device main body 12 by combination of rotational operation and sliding, the protruding direction of the door 30 on the way of opening/closing from the device main body 12 is selected arbitrarily, with no door 30 interfering when the door 30 is opened.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door device suitable for a so-called ceiling door which hides an operation unit or the like arranged on the surface of an electronic device such as a disk device.

[0002]

2. Description of the Related Art Some disc drives have a sealing door (hereinafter simply referred to as a "door") which hides an operation section thereof.
On the front panel. As shown in FIG. 9, the door 80 is connected to the bearing 8
4 so as to be rotatable. The bearing 84 is configured to rotate the door 80 over a range of 180 degrees, so that the door 80 rotates over a range of closed (as shown in FIG. 9A) and open (as shown in FIG. 9B). .

In the open state, the door 80 opens the front surface 87 of the front panel 86, that is, an operation unit (not shown) arranged on the front panel 86, and in the closed state, the door 80 hides the operation unit. Therefore, the door 80 prevents dust and the like from adhering to the operation unit and the like in the closed state.

[0004]

By the way, in the above-mentioned conventional example, as shown in FIG. 9B, when the door 80 is in the open state, an extra space by the length in the width direction of the door 80 is required. Therefore, in the open state of the door 80, the door 80
May get in the way. In particular, when there is an obstacle such as a separate speaker wall 90 on the opening direction side (the left side in FIG. 9) of the door 80 as shown by the one-dot chain line in FIG. 9B,
Since the door 80 cannot be opened sufficiently, the operation of the operation unit is inconvenient.

In the open state of the door 80, the operation section and the like are opened, and the back surface of the door 80 is also opened.
That is, when the door 80 is open,
Since 1 appears as an external appearance, the appearance deteriorates. Here, the rear surface 81 of the door 80 does not consider the appearance, that is, the appearance due to its configuration. Therefore, it is normally desirable to make the back surface 81 of the door 80 invisible.

[0006] For example, when the bearing is configured so that the door 80 can rotate by 270 degrees, the door 80 can be positioned on the side surface of the apparatus main body 82. However, also in this case, if there is an obstacle on the opening direction side of the door 80,
The door 80 is in the way while the door 80 is being opened, and the door 80 cannot be located on the side surface of the apparatus main body 82. Further, even if the bearing is configured so that the door 80 can be rotated by 270 degrees, when the door 80 is located on the side surface of the apparatus main body 82, the back surface 81 of the door 80 becomes visible, so that the appearance is deteriorated. .

In view of the above circumstances, the present invention provides a door device that gives a degree of freedom in the opening and closing directions of a door in consideration of the above circumstances.

[0008]

According to the present invention, there is provided an apparatus body, a door concealing a surface of the apparatus body, connecting means for rotatably connecting the door to the apparatus body, and connecting the door to the apparatus body. And a sliding means for sliding the door with respect to a device, wherein the door is rotated and slid via the connecting means and the sliding means, thereby positioning the door on a surface other than the surface of the apparatus main body. .

[0009] The opening operation of the door is such that the door is rotated from a closed state facing the surface of the apparatus main body through the connecting means to a position along the side face of the apparatus main body, and then along the side face via the sliding means. To slide. In order to close the door, the reverse operation is performed.

According to the present invention, the door is positioned at a position along a surface other than the surface of the apparatus main body by a combination of the rotating operation and the sliding operation. Can be arbitrarily selected, and the door does not get in the way when the door is opened. Further, according to the present invention, even if there is an obstacle such as a wall on the opening direction side of the door, the door can be sufficiently opened, and even if the apparatus main body is installed on a wall or the like, the door is completely obstructed. do not become.

When the door is positioned outside the surface of the apparatus main body and the front surface of the door faces outward, the rear surface of the door is not located outside as in the conventional example. A state in which the user can visually recognize the back surface of the door is not achieved. That is, in the above case, the appearance is improved because the surface of the door faces outward.

[0012]

At both ends of the support shaft 42, bearing portions 48 having a substantially C-shaped cross section are arranged corresponding to the pins 46 of the support portion 44. An insertion portion 49 for fitting the pin 46 is formed in the bearing portion 48. Further, the insertion portion 4 is provided on the support shaft 42.
A cutout 50 corresponding to No. 9 is formed.

As shown in FIG. 5, a rotary shaft 52 (see a broken line in FIG. 5) is supported in the support shaft 42. Rotary axis 5
The length of 2 is shorter than the length of the support shaft 42 in the axial direction. Further, pinions 54 are attached to both ends of the rotating shaft 52, and cutouts 56 forming a part of the regulating means are formed at both ends of the support shaft 42. The notch 56 is formed corresponding to the pinion 54 in order to release a part of the pinion 54 from the support shaft 42.

Further, as shown in FIG. 2, on the rear surface of the door 30, ie, the base 32, a rack 58 is formed at a portion corresponding to the pinion 54 along the horizontal direction. And the pinion 54 always meshes with the rack 58,
The rotation of the pinion 54, that is, the rotation shaft 52 causes the entire door 30 to move at a constant speed. That is, according to the present embodiment, the upper and lower ends of the door 30 move at a constant speed.
The whole slides smoothly and reliably with respect to the support shaft 42.

A locking claw 60 constituting a part of the restricting means is formed on the support portion 44 in correspondence with the pinion 54 and the notch 56. In the closed state where the door 30 closes the panel surface 16 (the state shown in FIGS. 3 and 4A),
As shown by the broken line in FIG. 3, the gear teeth 55 of the pinion 54 corresponding to the cutouts 56 are caught by the locking claws 60 and restrict the rotation of the pinion 54. Therefore, when the door 30 is in the closed state, the sliding of the door 30 is restricted, and the door 30 does not slide carelessly.

On the other hand, in the open state where the door 30 opens the panel surface 16 (the state shown in FIGS. 1, 4B and 5),
As shown in FIG. 6, when the door 30 rotates about the pin 46, the pinion 54 separates from the locking claw 60. Therefore, the pinion 54 is in a rotatable state, and the door 30 is slidable with respect to the support shaft 42.
That is, in the open state where the door 30 is opened to the position along the side surface 13 of the apparatus main body 12 (the state shown in FIGS. 1 and 6), as shown in FIGS.
You can slide along.

At both ends of the support shaft 42, as shown in FIG.
The engagement pin 62, which is a cylindrical positioning means,
8 is disposed on the door 30 side. On the other hand, on the door 30, a contact portion 64 on a straight line extending in the horizontal direction is formed corresponding to the engagement pin 62. As shown in FIGS. 2, 6, and 8, the abutting portion 64 has a locking protrusion 65 as a positioning means for positioning the engaging pin 62 at a predetermined position.
And 66 are formed.

That is, the locking projections 65 and 66 have a substantially V-shaped planar shape. As shown in FIG. 6, the locking projection 65 is provided with an abutting portion 64 so that the support shaft 42 can be positioned at one end of the door 30 (the left side in FIG. 4A).
Is disposed on one end side of the. On the other hand, as shown in FIG.
The locking projection 66 connects the support shaft 42 to the other end of the door 30 (FIG. 4A).
In this case, it is disposed on the other end side of the contact portion 64 so as to be positioned on the right side.

As shown in FIG. 2, a linear guide groove 70 extending in the horizontal direction is formed in the door 30 between the contact portion 64 and the rack 58. On the other hand, a slider 72 is attached to the support shaft 42 so as to correspond to the guide groove 70, and a tip portion 73 of the slider 72 is fitted into the guide groove 70. That is, the sliders 72 are disposed at the upper and lower ends of the door 30 in order to move the entire door 30 equally. Therefore, the slider 72 is moved
Therefore, the entire door 30 slides smoothly and reliably with respect to the support shaft 42.

A leaf spring 74 is attached to the support portion 44 between the pin 46 and the locking claw 60. At the tip of the leaf spring 74, an engaging portion 75 bent in a substantially V shape is formed. As shown in FIG. 3, the base end 74A of the leaf spring 74 is fixed to the inside of the front panel 14 by a fixing means such as a screw (not shown). That is,
As shown in FIG. 6, the leaf spring 74 is set such that an urging force is generated when the engagement portion 75 side is pressed.

On the other hand, a substantially disc-shaped engaging piece 76 is
Are arranged corresponding to the leaf spring 74, and the engagement piece 76 has a substantially arc-shaped outer peripheral portion 77 and engagement projections 78A and 78A.
8B are formed. Engagement projections 78A and 78B
Are substantially corresponding to the engaging portions 75 of the leaf spring 74, and are V-shaped.

The engaging portion 75 of the leaf spring 74 contacts the outer peripheral portion 77 of the engaging piece 76 or the engaging projections 78A and 78B. As shown in FIG. 6, in the open state where the door 30 is rotated by 90 degrees with respect to the panel surface 16, the engaging portion 75 of the leaf spring 74 is fitted between the engaging projections 78A and 78B of the engaging piece 76. Is positioned. As shown in FIG. 7, when the door 30 is further rotated (in a state where the door 30 is rotated 120 degrees with respect to the panel surface 16), the engaging portion 75 of the leaf spring 74 is 78B, it comes into contact with the outer peripheral surface of the engaging projection 78B and is positioned.

As shown in FIG. 2, a metal plate 37 is attached to the door 30 on the side of the locking projection 66 above the base 32. On the other hand, as shown in FIG. 1, a magnet 38 is provided on the main body 12 of the metal plate 3 when the door 36 is closed.
7 is attached to a portion corresponding to the same. And door 3

8 is attracted by magnetic force, and the door 30 is fixed with the panel surface 16 of the apparatus main body 12 closed.

The front panel 14 has a curved concave portion 79 formed above the magnet 38. The recess 79 is for easily opening the door 30, and opens the door 30 with a finger or the like inserted into the recess 79. The disk device 10 is provided with a receiving unit that receives a signal from a controller, which is a transmitting unit (not shown).

Subsequently, the panel surface 16 of the disk drive 10
The opening operation of the door 30, which is performed when the operation unit 20 arranged in the first embodiment is used, will be described. First, to open the door 30 in the closed state shown in FIG. 4A, the door 30 is rotated about the pin 46. When the door 30 is rotated, the support shaft 42 rotates while the engaging portion 75 of the leaf spring 74 shown in FIG.

Then, as shown in FIG.
When rotated to 0 degrees, the engagement portion 75 of the leaf spring 74 is fitted between the engagement protrusions 78A and 78B of the engagement piece 76,
Positioned. Although not shown, immediately before the engagement portion 75 is fitted between the engagement protrusions 78A and 78B, the engagement portion 75 is pressed by the top of the engagement protrusion 78A.
That is, in the present embodiment, the engaging portion 75 is
8A, when the engaging portion 75 crosses over the top portion,
The click feeling is obtained because it is biased by the top of 8A.

Further, as shown in FIG.
When rotated by 0 degrees, the engaging portion 75 is
Abuts on the top while being passed over the top, and is positioned. When the engaging portion 75 gets over the top of the engaging protrusion 78B, the engaging portion 75 is urged by the top of the engaging protrusion 78B, so that a click feeling is obtained. That is,
In the present embodiment, it can be easily recognized that the time when the click feeling is obtained is the time when the rotation of the door 30 ends.

The reason why the door 30 can be rotated over a 120-degree angle range between the closed state and the fully opened state is, for example, that the operation unit 20 is rotated while the door 30 is kept open. This is to prevent the door 30 from interfering with the operation of the operation unit 20 when an operation is desired.

In the closed state in which the door 30 closes the panel surface 16, as shown in FIG. 3, the pinion 54 is caught by the locking claw 60 and restricts the rotation of the pinion 54, so that the sliding of the door 30 is restricted. Door 30
Does not slide. That is, in the present embodiment, even when the door 30 is slid in the closed state, since the rotation of the pinion 54 is restricted by the locking claw 60, it is easier to rotate the pinion 54 about the support shaft 42. We can recognize that there is.

Here, the reason for restricting the sliding of the door 30 in the closed state is that it is difficult to determine the sliding amount of the door 30 in the closed state in advance, so the door 30 is slid in the closed state. In such a case, the bearing 4
This is because there is a high possibility of adding to 0. Therefore, in the present embodiment, since the sliding of the door 30 in the closed state is restricted, the possibility that an excessive load is applied to the bearing 40 is reduced, and the bearing 40 is prevented from being damaged.

As shown in FIG. 6, the door 30 is
In the open state rotated 90 degrees with respect to 6, the pinion 5
4 is separated from the locking claw 60 and becomes rotatable. Therefore, in the present embodiment, since the door 30 is slidable with respect to the support shaft 42, the door 30 can be slid along the side surface 13 as shown in FIGS. 4B and 5.

Here, the reason why the door 30 can be slid in the open state is that the sliding amount of the door 30 is predicted to some extent as shown in FIG. 4B (that is, the projected position of the door 30 corresponds to the panel surface 16). This is because the door 30 is less likely to slide more than necessary.

In the present embodiment, as shown in FIG. 6, since the engaging pin 62 is positioned in contact with the locking projection 65, the door 30 is positioned at the initial slide position. And when the door 30 is slid,
Since the locking projection 65 presses the engagement pin 62, the engagement pin 62 and the locking projection 65 are elastically deformed. Further, when the locking projection 65 gets over the engagement pin 62, the door 3
0 slides easily.

The upper and lower ends of the door 30 are slid at a constant speed by the pinion 54 and the rack 58, and the guide groove 70 and the slider 72. Then, as shown in FIG. 8, when the locking projection 66 is positioned over the engagement pin 62, the door 30 is positioned at the slide completion position. That is, according to the present embodiment, since the locking protrusion 65 or 66 is positioned by the engagement pin 62, the door 30 is reliably positioned at the initial slide position or the complete slide position, and does not slide carelessly. .

In this embodiment, FIG. 4B or FIG.
Since the door 30 is slid to the position along the side wall 13 and positioned at the slide completion position, the door 30 does not protrude from the apparatus main body 12 and does not become an obstacle as in the related art. That is, according to the present embodiment, the door 30 is positioned at a position along the side surface 13 other than the panel surface 16 of the apparatus main body 12 by a combination of the rotation operation and the slide operation. The direction of projection from the apparatus main body 12 can be arbitrarily selected, and the door 30 does not interfere when the door 30 is opened.

According to the present embodiment, as shown by the dashed line in FIG. 4B, the door 30 is opened in the opening direction (in FIG. 4,
Even if there is an obstacle such as a wall 90 of a separate speaker (not shown) on the left side), the door 30, that is, the operation unit 20 can be sufficiently opened, and the apparatus main body 12 is installed on the wall 90 or the like. However, the door 30 does not get in the way at all.

In the present embodiment, the closed door 30 is rotated by 90 degrees and then slid along the side surface 13. Therefore, the door 30 located at the slide completion position, that is, the surface of the mirror body 34 is set. Is located on the outside. That is, according to the present embodiment, as shown in FIGS. 4B and 5, when the door 30 is located at the slide completion position, the rear surface of the door 30 is not located outside as in the conventional example. 30, that is, the back surface of the base 32 does not become visible. Therefore, according to the present embodiment, since the surface of the door 30, that is, the surface of the mirror body 34 faces outward, the appearance is improved.

Next, to bring the door 30 into the closed state shown in FIG. 4A, the door 30 is moved in a procedure reverse to the above procedure. That is, the door 3 located at the slide completion position
0 is slid to the position indicated by the imaginary line in FIGS. 4B and 5, and then rotated toward the panel surface 16 via the bearing 40. When the door 30 moves to a closed position that hides the panel surface 16, the door 30 is positioned by the metal plate 37 and the magnet 38.

Accordingly, in the present embodiment, the door 30 is
By positioning the door 30 at the closed position shown in FIG. 4A, the door 30 hides the panel surface 16, that is, the operation unit 20, and the like, so that adhesion of dust and the like to the operation unit 20 and the like is prevented. FIG. 4A
1, the display unit 18 shown in FIG.
Can be visually recognized from the outside of the door 30 via the window 36 and the mirror body 34, so that the display content displayed on the display unit 18 can be recognized.

In this embodiment, by loading a disc (not shown) into the disc insertion slot 26 and performing a reproducing operation, a reproduced sound is output from a headphone or a speaker (not shown). According to this embodiment, even when the door 30 is closed, the disc loading unit 22 is open, so that the disc can be inserted into or taken out of the disc insertion slot 26.

Even when the door 30 is closed, various operations such as play can be performed by using the controller. The processing related to the disc or the tuner is the same as that of a normal audio device, and the description is omitted.

In the above embodiment, the door 30 is set so as to cover only the panel surface 16, but the door 30 may be set so as to cover the disk loading section 22 as well. Further, the present invention may be configured so that the apparatus main body can be installed upside down. That is, the installation direction of the apparatus main body according to the present invention can be arbitrarily changed. Further, the configurations of the pinion 54 and the rack 58 as the sliding means according to the present invention can be arbitrarily changed.

In the present invention, the mounting position (for example, left and right) of the bearing can be arbitrarily changed, and the order of the rotation operation and the sliding operation of the door with respect to the bearing can be arbitrarily changed. That is, in the present invention, when the door is opened, the door may first be slid and then rotated, and in this case, the door at the slide completion position may be an upper surface other than the side surface of the apparatus main body. .

Further, in the present invention, the storage portion for storing the door may be provided at the side corresponding to the slide completion position where the door is slid to the position along the side surface of the apparatus body. Furthermore, in the above embodiment, the door device is applied to a disk device, but the door device of the present invention can be applied to a television, a personal computer, and the like.

[0052]

As described above, according to the present invention,
Since the door is configured to be positioned along a surface other than the surface of the apparatus main body by a combination of the rotating operation and the sliding operation, the direction in which the door protrudes from the apparatus main body during opening and closing of the door can be arbitrarily selected. The door does not get in the way when opened.
