It is in a double-enclosed state. The sound output from the built-in speaker 32c is reverberated in the space 32v and released to the outside through the sound emission hole 21s. The void 32v becomes a part like a guitar or a violin body.

  Further, the side surfaces 2d and 2e are shaped to bulge outward through upper and lower taper step portions 2d1 and 2e1, and partial bulge portions 2d2 and 2e2 are formed one by one on the upper and lower sides. The bulging portions 2 d 2 and 2 e 2 form a bulge outward from the main body case 2 and give the main body case 2 a volume feeling. This volume feeling is further emphasized by the presence of the constricted portions 2d3 and 2e3 in the middle of the height direction. In FIG. 7, reference numeral 2e4 is a recess such as a logo formed as a recessed portion. The recess 2e4 such as a logo is formed as necessary, and may be formed on a flat surface as shown in FIGS.

  FIG. 8 is a cross-sectional view taken along the line BB cut so as to pass through the three push buttons 11 to 13 and a plan view showing the cutting position and the arrow direction. Similar to the A-A cross-sectional view, the side surfaces 2d and 2e have taper step portions 2d1 and 2e1, bulge portions 2d2 and 2e2, and constricted portions 2d3 and 2e3 that give a volume feeling. The push buttons 11 to 13 are in contact with tact switches 32 e to 32 g installed on the second substrate 32. And the protruding rib frames 2c1 to 2c3 are formed on the upper surface 2c so as to surround the push buttons 11 to 13. As a result of the ridge frames 2c1 to 2c3 surrounding the push buttons 11 to 13, the height of the push buttons 11 to 13 is inconspicuous.

  The SD card slot component 33a is mounted so that the tip is exposed from the elongated groove-like opening 21m on the right side surface 2d. A recess 21m1 having a thickness of about ½ surrounds the periphery of the long and narrow groove-shaped opening 21m. By forming the recess 21m, the SD card can be inserted and removed smoothly. In FIG. 8, reference numeral 2d4 is also a recess such as a logo formed as a recessed portion, and may be formed on a flat surface as shown in FIGS.

  FIG. 9 is a cross-sectional view taken along the line C-C cut so as to pass through the central push button 12, and a plan view showing the cutting position and the arrow direction. It can be seen that the front and back sides of the upper surface 2c and the front and back sides of the bottom surface 2b of the main body case 2 are configured by R-curved curved surfaces 2c4, 2c5, 2b1 and 2b2. Due to the presence of the curved surface 2c4 and the like, the information display device 1 is also provided with a smooth and soft image that is not angular. In the present embodiment, the back surface 2f is provided with the rectangular recess 21h for attaching the serial number seal 43, but a flat back surface shape without a recess may be used.

  FIG. 10 is a cross-sectional view taken along the line DD at the center in the front-rear direction, and a plan view showing the cutting position and the arrow direction. Also from this figure, it can be seen that the side surfaces 2d and 2e have tapered step portions 2d1 and 2e1, bulge portions 2d2 and 2e2, and constricted portions 2d3 and 2e3 that give a volume feeling. Reference numeral 2d5 written on the card slot is a portion where the type of the SD card is displayed in engraving format, but this may also be a flat surface as shown in FIGS.

  Next, the positional relationship between the substrates 31 to 34 will be described with reference to FIG. 11 showing a state in which the upper case and the front case are removed.

  As shown in the figure, the first substrate 31 to the third substrate 33 are installed in a horizontal state with the plate surfaces directed in the vertical direction and spaced apart in the height direction. On the other hand, the display substrate 34 is installed in a vertical state with the plate surface directed in the front-rear direction.

  Since the GPS module 32a is installed on the upper surface of the first substrate 32 mounted in the horizontal state on the top, it is easy to receive radio waves from GPS satellites. On the other hand, since the radar module 31a, which is the heaviest part, is installed on the first substrate 31 at the bottom, the center of gravity of the apparatus can be lowered. Since the SD card slot part 33a and the external input terminal receiving part 33b of the third board 33 face the right side, the user in the driver's seat inserts / removes the SD card, or inserts / removes the output terminal such as a portable music player. The operation is easy.

  In addition, since the patch antenna 31c is installed in an upright state on the back side of the first substrate 31 attached at the bottom, it is easy to catch a microwave or the like from the front of the vehicle. Further, since the slide switch component 32b is installed on the left side of the rear end of the uppermost second board 32 and the DC jack receiving component 31b is installed on the right side of the rear end of the first board 31 of the lowermost part, the DC jack and the slide switch are installed. It is not conspicuous from the front surface, and can be arranged at positions separated from the top, bottom, left and right on the back surface. As a result, the power cord of the DC jack is not accidentally disconnected when the slide switch is operated.

  Unlike the first to third substrates, the display substrate 34 is attached in the vertical direction, so that four substrates can be stored in the compact main body case 2 in a proper manner.

  According to the information display device 1 of the first embodiment, the main body case 2 is formed in a dice-like outer shape having substantially the same width, height, and depth, so that the design is interesting and the first to third substrates 31 to 31 are provided. By attaching 33 with the plate surface facing up and down, an electronic component for demonstrating the original function of the information display device 1 can be accommodated in a dice-shaped main body case. As a result, it is possible to provide an information display device that has no hindrance in demonstrating the original function and is attractive as an interior in a vehicle from a “die-like” feeling of a dice shape.

  In addition, by placing the first substrate 31 with the relatively heavy radar module 31a on the lower side, the overall weight balance of the apparatus is improved, and the forward falling moment due to the weight of the display unit 10 mounted on the front surface is improved. It has been countered. Furthermore, since the GPS module 32a is installed on the uppermost second substrate 32, it is easy to receive radio waves from GPS satellites. In addition, since the patch antenna 31c is installed on the back side of the first substrate 31 so as to be substantially parallel to the back surface 2f of the main body case 2, the radar module 31a has a sufficiently high detection capability and is compact. Design is possible.

  Further, the slide switch component 32b is installed on the left side of the rear end of the second substrate 32 at the top, and the DC jack receiving component 31b is installed on the right side of the rear end of the first substrate 31 on the bottom. The OFF operation is easy to perform, and the power cord is not touched and pulled out during the ON / OFF operation.

  In addition, by providing the third substrate 33 and being a vehicle-mounted information display device, the function as a music playback device is exhibited, so that the fun of the function can be provided in addition to the fun of the design. And since push button 11-13 required in order to demonstrate the added music reproduction function was installed in the area | region of the upper half of the upper surface of main body case 2, since the circumference | surroundings were enclosed by the protruding frame 2c1-2c3, design property In addition, it is easy to operate and can be operated without touching the switch or power cord on the back.

  In addition, the built-in speaker 32c is installed on the upper surface of the uppermost second substrate 32, the sound emitting holes 21s are formed in a grid shape on the upper surface 2c of the main body case 2, and the recess 21t has a sense of unity in design. Do not make the speaker stand out. Between the speaker 32c and the sound emission hole 21s, there is a space 32v doubled by the oval cylindrical walls 21u and 21w, so that the sound reverberates and voice information such as warning / warning is transmitted to the speaker. The sound can be clearly communicated to the driver.

  The main body case 2 is formed on the upper case 21 integrally formed on the upper surface, the side surface, and the rear surface, the bottom case 22 constituting the bottom surface, the upper front edge 2g formed on the upper front surface of the upper case, and the front surface of the bottom case. Since the front case 23 fitted into the back side of the lower front edge 2h is assembled and configured so that the display substrate 34 with the liquid crystal display 34a is attached to the back side of the front case 23, the main body case 2 is made sturdy. It is easy to assemble while having a structure, and the display panel can be securely attached.

  In addition, since the touch panel 41 is attached to the front side of the display opening of the front case 23, various settings and the like can be performed by natural operations together with the contents of the display display, and the design by providing a switch or the like. The adverse effects of can be eliminated.

  Furthermore, since the front and rear sides of the upper surface of the main body case 2 and the front and rear sides of the bottom surface are formed of curved surfaces 2c4, 2c5, 2b1, and 2b2 that are rounded, a smooth image "lumpy" can be given. If it rolls, the direction of rolling is presumed, and even if it hits the user, it gives a “feeling of security” that it does not hurt.

  And even if it is a speed control monitoring apparatus, since the main body has a dice shape and has “a feeling of mass”, “a feeling of crispness”, “a mechanical impression”, etc., it can be easily accepted as an interior in a car without a sense of incongruity.

  In addition, the information display device 1 according to the first embodiment realizes a music reproduction function by a main control microcomputer mounted on the back surface of the display substrate 34. Specifically, music data is read from the SD card inserted into the SD card slot, reproduced, and output via the FM transmitter 33c, so that the reproduced music can be played from the speaker of the in-vehicle audio apparatus. This music reproduction is executed by instructing music selection / reproduction such as pause / performance, return, and feed by operating the push buttons 11 to 13 on the upper surface. Even when an external device such as a portable music player is connected to the external input terminal and music is played from the external device, music is transmitted to the in-vehicle audio device via the FM transmitter 33c and comfortably via the in-vehicle speaker. You can also enjoy it.

  Note that the FM transmitter 33c may be larger, and may occupy more area on the board than the GPS module 32a. In the first embodiment, the FM transmitter 33c is provided on the surface of the substrate 33. However, the FM transmitter 33c may be provided on the back surface of the substrate.

  Further, in the first embodiment, the touch panel 41 is illustrated as having a surrounding mounting frame and a touch surface that is recessed from the mounting frame, but instead of the mounting frame, using a transparent flat panel panel, The part corresponding to the screen of the flat panel remains transparent, the part other than the part corresponding to the screen is printed in black from the back, the part other than the part corresponding to the screen is masked, and the part corresponding to the screen is transparent. A touch panel may be provided on the remaining surface. In this way, since the front surface is a simple flat plate, it is possible to give a more lumpy feel.

  Next, a manufacturing example of the main body case 2 will be described as a second embodiment. As shown in FIG. 12, W = 56 mm, H = 54 mm, D = 53 mm, and the side bulge is 0.5 mm. In addition, the side surface is made of metal and the other side is matte. Furthermore, a convex sculpture is given to the upper part of the SD card insertion slot and the external input terminal insertion slot on the right side, and a concave sculpture is given to the constricted part to finish it in a sheet metal style. Further, a symbol indicating the function of the push button, a device type, and the like are printed on the upper surface. The main body case is a synthetic resin injection molded product.

  According to this production example, “matte coating” gives a “class feel” to a high-class feeling, and “metal-like paint” protects the contents firmly, while “metal-like paint” A “mechanical impression” is formed by a part of the applied side surface protruding in front view. In addition, the sculpture on the right side gives the image of sheet metal together with the metal-like painting, further enhancing the mechanical impression.

  According to Example 1 and its manufacturing example (Example 2), for example, when installed in a vehicle such as a dashboard, the driver can visually recognize the information, and there is a problem in performing the original function. It is possible to provide an information display device that is attractive as an interior in a vehicle.

  As mentioned above, although the Example for implementing this invention was described, this invention is not limited to these, The various change in the range which does not deviate from the summary is possible.

  For example, the present invention can be applied to a car navigation device and other in-vehicle electronic devices.

  The present invention can be used in in-vehicle electronic devices for automobiles.
