Abstract

PROBLEM TO BE SOLVED: To provide a user-friendly electronic apparatus and a vehicle using the same.SOLUTION: The electronic apparatus has a drive motor 22 with a rotation drive shaft 23 on which a rotational load member 26 is abutted in a state being biased. Therefore, even when a user make a touch operation (actually, a gentle push operation) on a display, which is larger than an opening part of a body case, since the drive motor 22 is positioned at the rear side of a connection, the rotation drive shaft 23 is hardly rotated. As a result, a drive gear 24, a follower gear 21 and a slider which are positioned at the front side of the rotation drive shaft 23 are also hardly moved. Thus, the display is prevented from being moved undesirably.

  In the above conventional example, the opening of the main body case is exposed by opening the display, and the recording medium is loaded into the main body case or the mounted recording medium is taken out of the main body case from the opening. Therefore, it is very convenient and widely used.

  In recent years, efforts have been made to increase the display size of electronic devices having such a configuration so that the display content on the display is easy to see.

  However, when the display is enlarged in this way, when the display is brought into contact operation (actually, a slight push-in operation), the display moves to the main body case side and is displaced. As a result, This makes it difficult to see the display and makes it unusable.

  In other words, as the display becomes larger, the distance from the pivot point of the display becomes longer, so that the display can be moved even with a small force, and in order to open and close the display, as described above, A slider is connected to the display, and a driven gear, a drive gear, and a drive motor are connected to the slider, so that the display abuts (actually, a slight push-in operation). As a result, the slider is pushed, and the driven gear, the drive gear, and the drive motor connected to the slider are sequentially rotated. As a result, the display moves toward the main body case and is displaced.

  For example, in a car, the display is slightly tilted to make it easier for the driver to see. However, when the display is pressed, this tilted state is changed. As a result, the display becomes difficult to see and is easy to use. It will be bad.

  Therefore, the present invention is intended to be easy to use.

  In order to achieve this object, the present invention provides a main body case provided with an opening for loading or unloading a recording medium, a display that covers the opening of the main body case so as to be opened and closed, and the display. And a slider provided in the main body case so as to be movable in and out through the opening, a driven gear connected to the slider in the main body case, a driving gear connected to the driven gear, and the drive The gear includes a drive motor mounted on the rotary drive shaft, and the display is made larger than the opening of the main body case, and the rotary load body is brought into contact with the rotary drive shaft of the drive motor in a biased state. In this way, the intended purpose is achieved.

  As described above, the present invention is connected to a main body case provided with an opening for loading or unloading a recording medium, a display that covers the opening of the main body case so as to be freely opened and closed, and the display. In addition, a slider provided in the main body case so as to be able to appear and retract through the opening, a driven gear connected to the slider in the main body case, a driving gear connected to the driven gear, and the driving gear are rotated. A drive motor mounted on the drive shaft, the display is made larger than the opening of the main body case, and the rotary load shaft is brought into contact with the rotary drive shaft of the drive motor in an energized state. It will be easy to use.

  That is, according to the present invention, since the rotary load body is brought into contact with the rotational drive shaft of the drive motor in the biased state, the display that is larger than the opening of the main body case is brought into contact operation (actually, As a result, the drive gear, driven gear, and slider in front of the drive motor are less likely to move. As a result, the display is less likely to move or displace inadvertently.

  In other words, even if the display is touched (actually, a slight push-in operation), the display is less likely to move and displace inadvertently, making the display easier to see and easier to use. is there.

  Hereinafter, an example in which an electronic apparatus according to an embodiment of the present invention is installed in a vehicle will be described with reference to the accompanying drawings.

(Embodiment 1)
In FIG. 1, reference numeral 1 denotes an automobile, and a driver's seat 3 and a passenger seat 4 are arranged in front of the vehicle interior 2.

  A handle 5 is disposed in front of the driver's seat 3, and an electronic device 6 is disposed between the driver's seat 3 and the passenger seat 4 in front of the handle 5.

  Speakers 7 for outputting reproduced sound of the electronic device 6 are disposed on the left and right sides of the vehicle interior 2.

  As shown in FIGS. 2 to 4, the electronic device 6 is provided with an opening 9 on the front surface of the box-shaped main body case 8, and the opening 9 is covered with a display 10 so as to be freely opened and closed.

  As is well known, the display 10 appropriately displays various information such as the volume of the sound, the song title, and the channel selection name when playing music or listening to the radio. , The map is displayed.

  Further, as shown in FIG. 4, a slit 11 for mounting or removing an optical disk (an example of a recording medium) and a memory (an example of a recording medium) are installed in the opening 9 of the main body case 8 opened by the movement of the display 10. The slits 12 and 13 for mounting or removing are exposed.

  Further, the lower left and right portions of the display 10 are connected to the front end of a slider 14 which is provided in the main body case 8 so as to be able to move in and out through the opening 9, as can be understood from FIGS.

  Further, a shaft (not shown) is provided in the upper left and right portions of the display 10, and this shaft is slidably disposed in guide grooves 15 provided in the left and right vertical directions of the opening 9.

  Such a configuration is well known, and if the slider 14 is pushed forward from the state shown in FIG. 2 to the outside of the opening 9 as shown in FIGS. 3 and 4, the lower part of the display 10 moves forward. As a result, the opening 9 is opened, and the slits 11, 12, and 13 are exposed.

  However, what is characteristic of this embodiment is that the display 10 is made larger than the opening 9 of the main body case 8, as can be understood from FIG.

  Specifically, as can be understood from FIGS. 2 and 3, the upper end of the display 10 is substantially the same position as the upper side of the opening 9 of the main body case 8, and the lower end of the display 10 is the opening of the main body case. In such a configuration, the display 10 is configured to open the opening 9 of the main body case 8 by moving the lower side forward as shown in FIGS. 3 and 4. It is said.

  A plate 16 is provided on the lower opening edge of the opening 9 of the main body case 8 so as to face the lower back side of the display 10 which is larger than the opening 9 of the main body case 8 as described above. This is provided to protect the display 10 when the electronic device 6 is transported to the production factory of the automobile 1, and this is not always necessary.

  That is, in the production factory of the automobile 1, the main body case 8 of the electronic device 6 is inserted and mounted in an opening (not shown) provided in front of the interior 2, and in this state, the display 10 is provided in front of the interior 2. It is in the state arrange | positioned outside the open part (not shown).

  At this time, in the interior 2 of the automobile 1, the display 10 is in a vertical state as shown in FIG. 2, but in a tilted state where the lower part is pushed forward slightly as shown in FIG. 3 according to the preference of the driver. Be utilized.

  That is, the operation is performed in the state shown in FIG. 3, the state shown in FIG. 3 is released to the state shown in FIG. 4, and then the state shown in FIG. 3 is used again.

  In the present embodiment, in order to open and close the display 10 as described above, the body case 8 is provided in the lower left and right portions of the display 10 through the opening 9 as understood from FIGS. The front end of the slider 14 provided so as to be able to move in and out is connected.

  The slider 14 is slidably disposed on a metal chassis 17 shown in FIG.

  The chassis 17 is arranged on the bottom surface in the main body case 8.

  A rack gear 18 is formed on the slider 14 as shown in FIG. 5, and driven gears 19, 20, 21 connected to the rack gear 18, and a drive gear 24 mounted with a rotary drive shaft 23 of the drive motor 22 are attached to the chassis 17. It is in the installed state.

  That is, if the drive motor 22 is rotated forward, the chassis 17 is pushed out of the opening 9 of the main body case 8 through the drive gear 24, the driven gears 21, 20, 19, and the rack gear 18, and as a result, The display 10 is opened from the tilted state of FIG. 3 as shown in FIG.

  Further, when the drive motor 22 is reversed from the state of FIG. 4, the chassis 17 is drawn into the opening 9 of the main body case 8 via the drive gear 24, the driven gears 21, 20, 19 and the rack gear 18. As a result, the display 10 is operated from the open state of FIG. 4 to the tilted state of FIG. 3, that is, the closed state.

  In such a configuration, as described above, the feature of this embodiment is that the display 10 is made larger than the opening 9 of the main body case 8 so that it can be easily seen.

  However, when the display 10 is enlarged in this way, when the display 10 is brought into contact operation (actually, a slight push-in operation), the display 10 moves to the main body case 8 side and is displaced, As a result, it becomes difficult to see the display 10 and it becomes inconvenient.

  This point will be described with reference to FIGS. 8 and 9. Since the operation unit 25 is arranged below the display 10 as shown in FIG. 3, the display 10 in the inclined state as shown in FIG. The downward direction is a slight pushing operation when the operation unit 25 is operated.

  That is, as shown in FIG. 9, if the display 10 is of the same size as the opening 9 of the main body case 8, the distance from the axis on the top of the display 10 that moves through the guide groove 15 to the operation unit 25 is short. The force to push the display 10 by 25 operation is small.

  On the other hand, when the display 10 becomes larger than the opening 9 of the main body case 8 as in the present embodiment, the distance from the rotation fulcrum of the display 10 becomes longer, so the display 10 can be moved even with a small force. It will be possible.

  Therefore, in the present embodiment, as shown in FIG. 7, the rotary load body 26 is brought into contact with the rotary drive shaft 23 of the drive motor 22 through a spring 27 in a biased state.

  More specifically, a D-cut surface 28 is formed on the distal end side of the rotary drive shaft 23, and the rotary load body 26 is brought into contact with the D-cut surface 28 in an urging state.

  The rotary drive shaft 23 was made of metal, and the rotary load body 26 was made of synthetic resin.

  Further, the rotary load body 26 is disposed on the opposite side of the driven gear 21 with the rotary drive shaft 23 interposed therebetween.

  With the above configuration, since the rotary load body 26 is in contact with the rotational drive shaft 23 of the drive motor 22 in the biased state, the display 10 that is larger than the opening 9 of the main body case 8 is contacted. Since the rotation drive shaft 23 of the drive motor 22 located behind the connection is difficult to rotate even if the operation (actually, a slight push-in operation), the conclusion is that the drive gear in front of the drive gear 22 is difficult to rotate. 24, the driven gears 21, 20, 19, and the slider 14 are also difficult to move, and as a result, the display 10 is less likely to be moved or displaced inadvertently.

  That is, even if the display 10 is brought into contact (actually, a slight push-in operation), the display 10 is less likely to be moved or displaced inadvertently, so that the display 10 is easy to see and easy to use. It becomes.

  Further, since the rotary drive shaft 23 is made of metal and the rotary load body 26 is made of synthetic resin, it is assumed that normal wear is unlikely to occur in this portion.

  Further, since the D-cut surface 28 is formed on the distal end side of the rotary drive shaft 23 and the rotary load body 26 is brought into contact with the D-cut surface 28 in the biased state, the biased state is also stabilized. .

  Furthermore, since the rotary load body 26 is disposed on the opposite side of the driven gear 21 with the rotary drive shaft 23 therebetween, the drive gear 24 mounted on the rotary drive shaft 23 is urged toward the driven gear 21. As a result, the connection between the drive gear 24 and the driven gear 21 can be stabilized even during vibration and impact during driving of the automobile 1.

  Note that even if the rotary load body 26 is brought into contact with the rotary drive shaft 23 of the drive motor 22 in the biased state, the load is close to the rotary drive shaft 23 of the drive motor 22, so that the drive motor 22 is affected. In conclusion, it is not a load and can be driven sufficiently.

  On the other hand, if a load is applied to the slider 14, the rack gear 18, and the driven gears 19, 20, and 21 on the display 10 side of the rotational drive shaft 23, the load is distant from the rotational drive shaft 23 of the drive motor 22. , “Because of the lever principle (reduction ratio)” using gears, a large load is applied to the drive motor 22, and there is a possibility that the drive of the drive motor 22 may be hindered.

  As described above, in the present invention, since the rotary load body is brought into contact with the rotational drive shaft of the drive motor in an urging state, the display larger than the opening of the main body case is brought into contact operation (actually, In this case, the rotation drive shaft of the drive motor located at the back of the connection is difficult to rotate. As a result, the display is less likely to move or displace inadvertently.

  In other words, even if the display is touched (actually, a slight push-in operation), the display is less likely to move and displace inadvertently, making the display easier to see and easier to use. is there.

  Therefore, it is expected to be used as an electronic device and an automobile equipped with the electronic device.
