Description

  The present invention relates to an electronic device in which a recording medium is inserted and ejected, and more particularly to a flip mechanism of an electronic device in which the influence on the recording medium during insertion and ejection is suppressed.

  In recent years, in-vehicle electronic devices have become more and more multifunctional, and the recording media that can be used are not only for audio such as CD and MD, but also for video such as DVD and CD-ROM. . At the same time, in-vehicle electronic devices equipped with relatively large display devices are becoming more common so that navigation images, TV and DVD videos can be displayed, instead of conventional function-only display devices. is there.

  Such a display device for an in-vehicle electronic device has a space limitation in a vehicle, and therefore, as shown in Patent Document 1, many display devices are configured to be openable and closable on the front surface of the electronic device. When the display device is in the upright closed state, the insertion opening of the recording medium formed on the front surface of the electronic apparatus is covered, and when the display device is in the open state, the insertion opening is exposed and the recording medium is exposed. Is configured to be insertable / removable.

  By the way, the above-described in-vehicle electronic devices with advanced functions include, for example, a mechanism corresponding to three types for DVD, CD, and MD in a 2DIN size of 178 mm in width and 100 mm in height. It is necessary to provide a configuration in which an insertion port for each recording medium is provided. For this reason, when the display device is in an open state, the distance between one of the insertion ports and the display device may be very close. For example, as shown in Patent Document 2, if the CD insertion slot and the display device are close to each other, the CD recording surface may come into contact with the display device when the CD is inserted and ejected.

In order to cope with this, as shown in FIG. 7, the insertion / extraction frequency is relatively high, but the MD insertion port X1 whose recording surface is covered with a hard case is placed at the lowest position close to the display device Y. In addition, a concave shape (indicated by hatching in the drawing) is provided on the display device Y side to ensure a clearance that avoids interference with the MD. 7 shows an open state of the display device Y, C is a case of an electronic device, and X2 is a CD insertion slot.

  However, in the electronic apparatus as described above, since the insertion opening that can be provided in a position close to the display device is limited to that for the recording medium covered with the hard case, the usability and the design are limited. I get out. For example, a CD or DVD with an exposed recording surface needs to be inserted by grasping the outer edge, so the insertion slot is preferably relatively lower, and an MD or the like covered with a hard case is Since the upper and lower surfaces can also be gripped, the insertion port may be located above, but such an insertion port arrangement is difficult to employ. Further, since the recording medium covered with the hard case is thick, as described above, the display device side needs to have a special shape in order to ensure the clearance.

  The present invention has been proposed in order to solve the above-described problems of the prior art, and its purpose is to bring the insertion opening of the recording medium where the recording surface is exposed close to the lid that opens and closes. The provision of a flip mechanism for an electronic device that does not affect the recording surface at the time of insertion / ejection and has few usability and design restrictions.

The lid body is provided so as to be openable and closable, and a flip is provided between the lid body and the insertion port to block contact between the recording medium and the lid body.
According to the first aspect of the present invention, since the contact between the surface of the recording medium and the lid is prevented by flipping, even when the insertion port is provided close to the lid, the recording medium can be inserted and ejected. The recording surface is not affected.

According to a second aspect of the present invention, in the flip mechanism of the electronic device according to the first aspect, the flip is provided so as to be interlocked with the lid.
In the invention according to the second aspect as described above, since the flip is interlocked with the rotation of the lid, it does not take time and effort to rotate independently.

According to a third aspect of the present invention, in the flip mechanism of the electronic device according to the first or second aspect, the flip is a fulcrum set on the lower side with respect to the insertion opening by a substantially thickness of the flip. It is characterized by being provided so as to be rotatable about the axis.
In the invention according to the third aspect as described above, the space between the rotating flip and the insertion slot can be minimized, so that the space can be effectively utilized.

According to a fourth aspect of the present invention, in the electronic device flip mechanism according to any one of the first to third aspects, the electronic device includes a biasing unit that biases the flip in the opening direction of the lid. And
In the invention according to claim 4 as described above, when the lid is opened, the flip biased by the biasing means is also displaced in the opening direction, so that a special drive source or the like is not required and the mechanism is simplified. it can.

According to a fifth aspect of the present invention, in the flip mechanism of the electronic device according to any one of the first to fourth aspects, the flip has a protective sheet on a surface facing the recording medium inserted into and removed from the insertion port. Is provided.
In the invention according to the fifth aspect as described above, the recording surface moves on the protective sheet when the recording medium is inserted and ejected.

According to a sixth aspect of the present invention, in the flip mechanism of the electronic device according to any one of the first to fifth aspects, at least a display screen is provided on the lid.
In the invention according to claim 6 as described above, it is possible to reduce the size by sharing the space between the insertion slot and the display screen.

A seventh aspect of the invention is the electronic device flip mechanism according to any one of the first to sixth aspects of the invention, wherein the electronic device is for in-vehicle use.
In the invention according to the seventh aspect as described above, since it is possible to reduce the size, even an in-vehicle device having many space restrictions can be adapted without any inconvenience.

  As described above, according to the present invention, even if the recording medium insertion port where the recording surface is exposed is provided close to the lid that opens and closes, without affecting the recording surface during insertion and ejection, It is possible to provide a flip mechanism for an electronic device with few usability and design restrictions.

The best mode (embodiment) for carrying out the present invention will be specifically described below with reference to the drawings.
[Constitution]
[overall structure]
In this embodiment, as shown in FIG.1 and FIG.2, the cover body 2 provided with the display 21 is provided in the front part 1 of the main body case of an electronic device so that opening and closing is possible. An insertion port 11 for the disk D1 is formed in the front portion 1 in the vicinity of the lid 2 in the open state. Further, in the vicinity of the upper edge of the front portion 1, an insertion port 12 for the disk D2 is provided. A flip 3 is provided between the insertion slot 11 and the lid 2. The disks D1 and D2 are, for example, CDs that are not covered with a hard case or the like and have exposed recording surfaces.

[Flip and its mounting structure]
As shown in FIG. 3, the flip 3 is a rectangular plate that is long on the left and right, and a protective sheet 31 made of a natural or synthetic material is affixed to the upper surface (the surface facing the disk D <b> 1). The protective sheet 31 is preferably a non-woven fabric made of microfiber (for example, EXSEINE (registered trademark)), but is not limited thereto. Shaft portions 32 and 33 protrude on the left and right sides of the rear edge side of the flip 3.

  As shown in FIGS. 4 and 5, the flip 3 has its shaft portions 32, 33 inserted into the shaft holes 13 a, 14 a of the bearing portions 13, 14 provided on the left and right sides of the front portion 1. It is provided so that rotation is possible. The shaft holes 13 a and 14 a of the bearing portions 13 and 14 are provided at positions where the rotation fulcrum of the flip 3 is lower than the insertion opening 11 by the thickness of the flip 3.

  The shaft portion 32 of the flip 3 is inserted into the coil portion of the torsion coil spring 34. One end of the torsion coil spring 34 is locked to the groove 1 a of the front portion 1, and the other end is locked to the flip 3. Therefore, the flip 3 is biased in the direction of rotating downward (opening direction) by the torsion coil spring 34.

[Cover structure of lid]
As described above, the lid 2 is provided so as to be displaceable between the closed state in FIG. 1 and the open state in FIG. 2, and the structure that enables this is as follows. That is, the lid 2 is configured such that the display screen of the display 21 faces frontward in the closed state of FIG. 1, and the display screen of the display 21 faces upward in the open state of FIG. The slide pin 22 is provided at the upper position in the closed state of FIG. 1, and the connecting pin 23 is provided at the lower position.

  As shown in FIG. 4, guide portions 15 and 16 are provided on the left and right inner surfaces of the front portion 1, and guide holes 15 a and 16 a are formed in the guide portions 15 and 16. Since the guide holes 15a and 16a have upper portions extending in a substantially vertical direction and lower portions are smoothly curved toward the front side, the guide holes 15a and 16a have a substantially J shape as a whole. As shown in FIG. 6, the guide holes 15a and 16b are provided with slide pins 22 of the lid 2 so as to be slidable. When the slide pins 22 are at the upper ends of the guide holes 15a and 16b, When the slide pin 22 is at the lower end of the guide holes 15a and 16b, the open state shown in FIG. 2 is established.

  As shown in FIGS. 2 and 6, arms 17 are provided on the left and right sides of the front portion 1 of the electronic device so as to be movable back and forth by a drive mechanism (not shown). The distal end of the arm 17 is rotatably connected to the connecting pin 23. When the arm 17 is urged forward by the drive mechanism, the lower portion of the lid 2 is urged forward to open, and when the arm 17 is pulled rearward by the drive mechanism, the lower portion of the lid 2 Is attracted to the closed state. Note that the drive mechanism can be operated by an instruction input from an operation button, a touch panel, a remote controller, or the like, as in a normal function of an electronic device.

[Action]
The operation of the present embodiment having the above configuration will be described.
[initial state]
That is, in the initial state, as shown in FIG. 1, the lid 2 is in an upright closed state, and the flip 3 is also urged backward against the torsion coil spring 34 by the back surface of the lid 2. Therefore, it is in an upright state between the front part 1 and the lid 2. Normally, the user views the video displayed on the display 21 in the lid 2 in this state.

[Disc insertion / ejection]
Next, when inserting the disks D1 and D2, an instruction to open the lid 2 is input by operating a button or the like. Then, the arm 17 protrudes forward by the operation of the drive mechanism, the connecting pin 23 is urged forward, and the slide pin 22 moves downward along the guide holes 15a and 16a, so that the lid body 2 starts to fall down. As shown in FIGS. 2 and 6, the slide pin 22 reaches the lower ends of the guide holes 15a and 16a, and the drive mechanism stops. Thus, at the same time that the lid 2 is in the open state, the flip 3 is released from the urging force by the lid 2 and falls forward due to the urging force of the torsion coil spring 34. And the front lower part of the flip 3 will be in the state which got on the rear part of the cover body 2 used as the open state.

  As described above, when the lid 2 is in the open state, the insertion ports 11 and 12 are exposed, so that the disks D1 and D2 can be inserted into any of the insertion ports 11 and 12. In particular, when the disc D1 is inserted into the lower insertion slot 11, since the flip 3 exists between the disc D1 and the lid 2, the lid 2 does not contact the recording surface of the disc D1. Further, since the recording surface of the disk D1 moves above the protective sheet 31 affixed to the surface of the flip 3, damage is prevented even if it contacts. Further, when the disc D1 is ejected, the recording surface of the disc D1 moves on the protective sheet 31 on the surface of the flip 3, so that damage is prevented.

[Storing the lid]
When the lid 2 in the open state is stored in the front portion 1 again in the closed state as described above, an instruction to close the lid 2 is input by a button operation or the like. Then, the operation of the drive mechanism causes the arm 17 to be attracted rearward, the connecting pin 23 is urged rearward, and the slide pin 22 moves upward along the guide holes 15a and 16a, so that the lid body 2 stands up. start. And since the slide pin 22 reaches the upper end of the guide holes 15a and 16a and the drive mechanism stops, the lid body 2 stands upright as shown in FIG. Thus, at the same time that the lid 2 is closed, the flip 3 is urged rearward by the lid 2 and stands upright against the urging force of the torsion coil spring 34.

[effect]
According to the present embodiment as described above, when the disk D1 is inserted and ejected, the flip 3 prevents contact between the surface of the disk D1 and the lid 2, so that the insertion opening 12 is brought close to the lid 2. Even if it is provided, the recording surface of the disk D1 is not affected. In particular, since the recording surface of the disk D1 moves above the protective sheet 31 attached to the flip 3, damage due to contact is prevented. Further, since the pivot point of the flip 3 is set to the lower side by substantially the thickness of the flip 3, the distance between the pivoting flip 3 and the insertion slot 11 can be minimized, and the space can be effectively used. Can be used. It is not necessary to provide a special shape for avoiding interference with the disk D1 on the lid 2 side.

  Further, since the flip 3 rotates in conjunction with the rotation of the lid body 2, it does not take time and effort to rotate independently. Particularly, since the drive source is only the drive mechanism of the lid 2 and the flip 3 only needs to be urged by the torsion coil spring 34, the structure for turning the flip 3 can be made as simple and small as possible. In addition, since the display space and the insertion space can be shared in the in-vehicle device, it is possible to reduce the size and effectively use the limited space in the vehicle. In particular, it becomes easy to conform to standards such as 2DIN size.
