Description

  The present invention relates to an in-vehicle electronic device and a program.

  As one of in-vehicle electronic devices, there is a microwave detector (radar detector) that detects a microwave of a predetermined frequency band emitted from a speed measuring device installed around the road and outputs an alarm. Some velocity measuring devices cannot be detected by such microwave detectors. As an example, there is a type in which a loop-shaped coil is embedded in the ground and a vehicle speed is determined while detecting the vehicle passing over the coil, as called a loop type. Others detect the speed of the vehicle using light other than microwaves. Therefore, the installation position information of the speed measuring device is stored in advance, and when the current position approaches the stored installation position using GPS (Global Positioning System) information (when a predetermined relationship is established), There is also an in-vehicle electronic device that issues an alarm regardless of whether or not a wave is detected (Patent Document 1).

  This type of in-vehicle electronic device includes, for example, a flat rectangular case and is installed on a dashboard or the like. A display unit is provided on the front surface (the surface facing the vehicle rear side (driver side)) of the installed case. The alarm is performed by outputting alarm information composed of predetermined images, videos, characters, etc. to the display unit. In addition, a speaker is built in the case, and alarm information using sound is output from the speaker.

JP 2008-64588 A

  The alarm that appeals to the driver's vision uses the alarm information output to the display unit, so the area where the alarm information can be output is limited to the installation area of the display unit, for example, near the outer periphery on the front side of the case It was difficult to use and output alarm information. In addition to the display unit, for example, there is a type in which operation switch buttons are prepared on the front surface of the case between the side of the display unit and the periphery of the case. In such a type, alarm information cannot be output to the operation switch button arrangement region.

  The display unit is configured using a display module including a display panel such as a liquid crystal panel. The display module includes a display panel and a portion such as a drive circuit that is provided around the display panel and drives the display panel (hereinafter referred to as a portion of a driver or the like). Thus, the driver portion such as the driver cannot be displayed. Therefore, even if an operation switch button or the like is not provided on the front surface of the case and a layout in which a display module is arranged on the entire surface is taken, alarm information cannot be output to a portion such as a driver.

  In addition, if a large display module constituting the display unit is used in order to enlarge the display area, the cost increases. Therefore, in the alarm using the display unit, the display area cannot be enlarged and the impact is lacking.

  In order to solve the above-described problems, an in-vehicle electronic device according to the present invention is (1) an in-vehicle electronic device installed at a position that can be visually recognized by a driver, and is a light having a light emitting unit connected to an end portion. A light tube is provided, and the light tube is illuminated by the light from the light emitting unit, and the light tube is disposed at a position where the light emitted from the light tube is visible to the driver.

  The light tube includes a core material and a clad material formed so as to cover the outer periphery of the core material. Unlike an optical fiber used for optical transmission or the like, the interface between the core material and the cladding material is irregular in structure. Therefore, the light incident from the end face propagates while repeating total reflection at the interface between the core material and the clad material, and gradually leaks from the side surface due to the structural irregularity of the interface, so that the side surface shines. This light tube is also referred to as, for example, a side leakage type silicone optical fiber. The core material and the clad material are formed using, for example, elastomers having different refractive indexes (for example, the core material is a high-refractive index high-transparent elastomer and the clad material is a low-refractive index transparent elastomer), so that the light tube has high elasticity. It has flexibility and can be bent or bent at an arbitrary position.

  “Visible” means that the driver can check the light emitted from the light tube along with the light emission of the light emitting unit. That is, the presence of the light tube does not have to be visible or can be seen when the light is turned off. In this way, an impact can be given at the time of lighting. In addition, the light tube may be exposed to the outside, but for example, a transparent or translucent cover member that transmits various kinds of light, for example, may be disposed and covered in a portion facing the driver. . Even if it is the structure which covers a light tube with a cover member etc., the light tube which is light-emitting should just be visually recognized from the driver | operator side at the time of light emission of a light tube. The light emitting unit may be, for example, a single color or a full color output. A full color output is preferable because there are a wide variety of color development states.

  And the light which the light emission part radiate | emitted enters into a light tube from the edge part of a light tube, and that one part is radiate | emitted outside from the circumference | surroundings of a light tube, progressing in the inside of a light tube. Since the light shines along the shape of the light tube, the light can be visually recognized by the driver by arranging the light tube at an appropriate position on the front surface facing the driver of the in-vehicle electronic device.

  The light tube shines along the shape by attaching it to the on-vehicle electronic device in any shape of a straight line and a curve. Therefore, it becomes a light emitting source having a certain length, not a point like a lamp. Further, since a driver or the like corresponding to the light emission position is not required unlike the display module, it can be arranged near the periphery of the in-vehicle electronic device, for example. It can shine in a manner that cannot be obtained by a display unit using a conventional display module, and becomes a new output means using visual recognition. Furthermore, a display unit is preferably provided at a position that can be visually recognized by the driver. By arranging the light tube outside the display unit, the outside of the display area of the display unit also shines. By making the light emitted from the light tube one of the visual information, even if the display unit is small, it is more noticeable and has an impact on the driver, and the surprise effect is enhanced.

  By controlling the lighting of the light emitting part and adjusting the state of light emitted from the light tube, it makes sense to the light state, provides various information to the driver, and exhibits a healing effect It is good to make a surprise effect.

  (2) The said light emission part is good to take the structure connected to the both ends of the said optical tube. In the case of a light tube, light entering from the end exits from the surroundings as it travels through the light tube, so that the entire light tube shines as described in (1) above. Since the light is emitted from the surroundings as described above, for example, when the total length of the light tube is long, the light incident from one end may reach only the middle of the light tube and may not reach the other end. In particular, when the light tube is bent, more light is emitted from the bent portion, and the light reach distance is shortened. By making light incident from both sides as in the present invention, even a relatively long light tube in which light cannot reach the other end with one light emitting portion can be made to shine entirely.

  (3) It is good to control so that the luminescent color of the light emission part connected to the said both ends may differ. Different emission colors may be different in at least one of hue, saturation, and brightness, for example. For example, when the hues are different, such as red and blue, or when R, G, and B appear in 256 gradations, (255,0,0) color and (128,0,0) Even when only the R component is used as in the case of a color, the emission color is different even when the value of R is different. By using different luminescent colors, each light incident from both ends is mixed at a predetermined position on the light tube. Therefore, in the vicinity of both ends of the light tube, light is emitted with the light emission color of each light emitting unit, and light is emitted with an intermediate color between the two light emission colors at the predetermined position. The position of the intermediate part is determined by the light intensity difference between the two light emitting parts.

  (4) It is good to control so that the said luminescent color changes with progress of time. The change may be continuous (for example, change according to a sine wave) or discrete (for example, an ON / OFF rectangular wave). By changing the emission color over time, for example, it can appear as a gradation in which the emission color of the light tube gradually changes, or it can appear as if light is flowing.

  (5) It is good to control so that the light intensity difference of the luminescent color of the light emission part connected to the said both ends may change. When the light intensity difference is changed, the position of the intermediate point where the lights incident from both ends are mixed is changed. For example, if the light intensity of one light-emitting part is changed from small to large as the light intensity of one light-emitting part is changed from high to low, the light mixing position is changed from one light-emitting part side to the other light-emitting part side. Move to the club side. Therefore, this makes it appear as if light of an intermediate color is flowing.

  (6) On the premise of the inventions of (4) and (5), it is preferable that the emission color change patterns of the light emitting sections connected to both ends are shifted in phase by the same pattern. The change pattern is, for example, one in which the emission color changes gradually like a sine wave, a triangular wave, a rectangular wave that alternately switches between two types of emission color, and one type of emission color that is turned on / off (ON / OFF) There are various types, such as a rectangular wave, a combination of predetermined colors (for example, red → orange → yellow → green → blue → indigo → purple). Shifting the phase means, for example, shifting the period of a sine wave or the like by a predetermined angle (for example, 30 degrees, 60 degrees, etc.), shifting the rising timing of a rectangular wave, or changing the start color in the case of a predetermined color combination. It is something to change. In addition, the same pattern is changed to ON / OFF like a rectangular wave, and when the phase is shifted by 180 degrees, the colors are completely separated.

  (7) The R, G, and B values constituting the three primary colors of light may be controlled to change according to the set reference pattern, and the emission color of the light emitting unit may be changed. For example, the reference pattern may change R, G, and B with a sine wave, and the reference pattern of each value of R, G, and B may be shifted by 30 degrees and 60 degrees. Moreover, the reference pattern of each value may be the same or different. When different reference patterns are used, one may be a sine wave, the other may be a triangle wave, and the like may be swept. Various forms may be taken such as changing the peak value or changing the period even with the same sine wave. The change in emission color can be easily controlled, and the change in emission color can be made rich.

  (8) At least one of the period of the reference pattern that changes the value of R, the period of the reference pattern that changes the value of G, and the period of the reference pattern that changes the value of B It is good to make it different from the period of. The different periods are, for example, that one period is 1 second and the other two periods are 3 seconds. It becomes a more complicated change pattern, which is more interesting and impacts the driver.

  (9) The emission color of the light emitting unit may be controlled so as to change at a period that can be visually recognized by a human. The period which can be visually recognized is good to be 15-20 Hz, for example. In this way, the light in the light tube appears to be crushed. 10 Hz is not preferable because it blinks.

  (10) The light emitting unit may be a full color LED. In this way, it is possible to easily control the change in emission color.

  (11) It is good to control so that the display thing provided with a display part and the light of the said light tube may relate to the display thing output to the said display part. Examples of the display object include predetermined pictures / motifs and characters. The display unit and the light tube are fused, and the display area becomes larger than the display screen of the display unit. The edges of the display module constituting the display unit do not shine due to the driver or the like. On the other hand, if it is a light tube, it can arrange | position to the peripheral edge of the case of a vehicle-mounted electronic device as prescribed | regulated, for example to following (20). Therefore, the display object can be expressed using the entire front surface facing the driver of the case.

  For example, (12) a part of an object represented by the display object may be symbolized by the light tube, or (13) an object associated with the shape of the light tube. May be displayed on the display unit. Some of the objects, for example, output a picture of a dragon on the display unit and symbolize the tail of the dragon with a light tube. As another example, for example, by arranging the light tube in an arc shape on both sides of the display unit, the outer periphery of the goggles can be formed by the display on the light tube and the display unit, or the face can be output to the display unit and light There are things that make tubes a symbol of ears. There are letters, pictures, and motifs associated with them. For example, the light tube is arranged in an arc shape on both sides of the display unit, the letter “X” is output to the display unit, and the end of the light tube and the letter “X” are continued to express “∞” as a whole. There is something to do. It may be the continuity of the shape, or it may be conceptually connected or recalled.

  (14) The display object to be output to the display unit may be connected to the light of the light tube. By doing so, the continuity and sense of unity between the display object to be output to the display unit and the light tube are strengthened, and it is easy to understand.

  (15) The display object to be output to the display unit is a moving image, and the light in the light tube may be controlled to change in accordance with the movement. For example, you can output a video of a creature such as a dragon on the display, and change the light of the light tube that symbolizes the dragon's tail according to the movement of the dragon's direction or approaching from the back to the near side. It is. In another example, when light moves from one end to the other end in the light tube and reaches the other end, light enters the display unit from the other end and moves in the display unit. As in the latter case, the output of the moving image on the display unit and the light tube may not shine simultaneously, and a time lag may be generated.

  (16) The length of the light tube may be longer than the length of the side of the display unit. When the length of the light tube is longer than the length of the side of the display unit, the light tube can be disposed so as to protrude outward from the outer peripheral edge of the display unit. Visual information by light can be emitted in a wide space.

  (17) The light emitting unit may be disposed on the back side of the display unit. The light emitted from the light emitting unit can be hidden by the display unit. Further, it is not necessary to provide an installation area for the light emitting unit outside the display unit, and the appearance of the in-vehicle electronic device can be reduced.

  (18) A part of the light tube may be disposed on both the left and right sides of the display unit, and both ends of the light tube may be disposed on the upper side and the lower side of the display unit. In particular, one end of the light tube is preferably disposed on the upper side of the display unit and the other end is disposed on the lower side. For example, when there is a driver or the like on one side of the display module constituting the display unit, the display cannot be performed on the driver or the like. Therefore, if the end of the light tube is arranged on a certain side such as a driver, the connection with the display object displayed on the display unit is deteriorated, but the connection between the display object and the light tube is improved by arranging on the upper and lower sides. be able to. Furthermore, if the both ends of the light tube are drawn from the positions where the upper and lower sides are symmetrical, the symmetry is also obtained, and the visual stability is also improved.

  (19) A switch unit may be provided at the display unit, and the light tube may be disposed so as to wrap around the outside of the switch unit. In the embodiment, the “SOTO” of the display unit adopts a layout in which the switch unit is arranged beside the display unit, but may be arranged above or below the display unit. By arranging the light tube outside the switch unit arranged outside the display area of the display unit, the light emission source can be arranged outside the switch unit beyond the display area of the display unit. Visual information can be emitted in a wider space. Further, for example, if the light emission state of the light tube is changed according to the operation state of the switch unit, when the switch unit is operated by hand, the light state surrounding the operating hand changes. Become. In this way, even if a part of the light tube is hidden by the hand that operates the switch part, it can be prevented that the entire light tube is hidden, and the operation of the switch part is more reliably recognized as reflected in the device. it can. In addition, since the changing light illuminates the hand from behind, it is easier to realize that it has changed according to the state operated by the hand.

  (20) The said light tube is good to arrange | position along the front side outer periphery of the case of a vehicle-mounted electronic device. In this case, the body line may be lifted along the appearance of the case of the in-vehicle electronic device. For example, it is possible to easily grasp to what extent a case of an in-vehicle electronic device exists at night by light emission of a light tube.

  (21) A groove is formed on the mounting surface of the light tube, the light tube is located in the groove, and the inner peripheral surface of the groove is preferably dark. Although the dark color is black in the embodiment, the dark color is not limited to black and may be a dark color. When the back surface of the light tube is white, the light emitted from the light tube cannot be clearly seen. On the other hand, a dark color such as black is preferable because the light from the light tube looks beautiful. In particular, in the case of an on-vehicle electronic device, light from the light tube may be difficult to see during the daytime due to light entering from outside the vehicle, such as on a western day, but by using a dark color, light from the light tube can be reliably seen. Since the light tube is embedded in the groove and becomes black not only in the background but also in the surroundings, it can be seen that the light tube is shining even from an oblique direction.

  (22) The light emitting unit is disposed on a back surface of the substrate, the light tube is disposed on a front surface side of the substrate, and an end portion of the light tube is routed to the back surface side of the substrate to be connected to the light emitting unit. Good. By hiding the light emitting part on the back surface of the substrate, only the light of the light tube can be visually recognized from the outside. In the case of a type including a display portion, the back side of the display portion may be positioned on the surface side of the substrate. In particular, it is preferable that the back surface of the display portion be fixed to the surface of the substrate. By arranging the light emitting part on the back side of the substrate, the light tube can be placed close to the periphery of the display part, and the continuity and relationship between the light of the light tube and the display object output to the display part can be understood. Since it becomes easy, it is preferable. Further, since the light tube can be arranged in a narrow space, the light tube can be arranged even if the periphery of the display unit and the periphery of the in-vehicle electronic device are narrowed.

  On the other hand, if the structure which puts a light emission part (for example, LED) on the front side of a board | substrate is taken, it will arrange | position outside the display part arrange | positioned on the front side. However, the light emitting unit cannot be arranged in a narrow area from the display unit to the periphery of the case, and if it is placed, it is necessary to secure a large installation area for the light emitting unit outside the display unit. This is not preferable because the size is increased and a wasteful non-display area is generated around the display unit. Furthermore, it becomes difficult to ensure the continuity between the light tube and the display unit.

  (23) The light emitting direction of the light emitting unit is parallel to a substrate on which the light emitting unit is mounted, and a locking portion for positioning the end of the light tube is provided on the substrate on which the light emitting unit is mounted. In a state where the end portion of the light tube is attached to the locking portion, the end portion may be opposed to the light emitting direction of the light emitting portion.

  When the light tube is attached to the locking portion, the light tube can be fixed and the end portion of the light tube and the light emitting portion can be positioned, so that light can be efficiently injected into the light tube. The locking portion may be a one-touch type such as a clip. The one-touch type may be a clip that can be set by, for example, opening the distal end of the locking portion opposite to the base end of the mounting base and pushing the light tube from the open portion.

  (24) A first substrate on which the light emitting unit is mounted, and a second substrate on which an acquisition unit (sensor or the like) for acquiring an external situation is mounted, and the first substrate and the second substrate are in a driver's viewing direction. The first board may be positioned on the driver side. Arranging along the viewing direction suppresses an increase in the area viewed from the driver. The first substrate is, for example, a substrate for a light emission / display function. For a type including a display unit, for example, an LCD constituting the display unit, a microcomputer for controlling the LCD, or the like may be mounted. The second substrate (rear) is, for example, a substrate for mounting the basic functions of the in-vehicle electronic device. The external situation includes, for example, radar waves emitted from the vehicle speed measuring device, various radios, vehicle information, and the like. The first substrate and the second substrate are arranged separately for each function. For example, the second substrate may be composed of one or a plurality of substrates.

  (25) It is preferable to provide alarm means for issuing an alarm when an alarm condition is satisfied, and that the light from the light tube is used for the alarm. By making the light of the light tube one of the visual information, even if there is no display part or even if there is a display part, it is more conspicuous, has an impact on the driver, and the surprise effect becomes high. By using such a light tube for notification of a new alarm, the driver can be notified of the alarm more reliably.

  (26) On the premise of the invention of (25), the alarm means may change the light of the light tube in accordance with the type of alarm target. In this way, changing light includes various things such as changing the emission color, changing the light intensity of the emission color, changing the blinking state, and the like. The types of alarm targets may be classified according to the urgency level (importance level), for example. The driver can recognize the type of the alarm target based on the light state. In the case of a type equipped with a display unit, when the alarm information is output, if it has a function of indicating the target of the color corresponding to the type of the alarm target at the position of the alarm target, the light color of the light tube and the output to the display unit It should be the same as the target color.

  (27) On the premise of the inventions of (25) and (26), a display unit is provided, and the alarm means provides an alarm in which the display unit and the light tube are fused when a plurality of predetermined alarm conditions are satisfied. It is good to start. The plurality of alarm conditions may be simultaneous or may occur at different times. What occurs at different times, for example, satisfies the alarm conditions in the order in which they are set as the vehicle travels. Moreover, when it generate | occur | produces at different time, you may make the thing which is not a predetermined order. By issuing a combined alarm when a plurality of specific alarm conditions are satisfied, the generation of such an integrated alarm is reduced. Therefore, since the surprise performance when such a combined warning occurs is high and the impact given to the driver is increased, the driver can be notified of the warning more reliably. As for satisfying the alarm conditions in the order in which the vehicle travels, for example, when a radar is received and each alarm point of 2000m → 1000m → 500m passes in order, etc. Output. In this configuration, for example, the alarm means may not generate an alarm in which the display unit and the light tube are fused when a predetermined plurality of alarm conditions are not satisfied. For example, when other alarm conditions that do not satisfy a plurality of predetermined alarm conditions are satisfied, an alarm is issued by either the display unit or the light tube, and when the predetermined plurality of alarm conditions are satisfied, the display unit And the light tube may be combined to emit an alarm.

  (28) An acquisition unit that acquires an external situation may be provided, and light emission of the light emitting unit may be controlled based on the external situation acquired by the acquisition unit. (29) The external situation may be vehicle information. The vehicle information may be obtained from, for example, OBD information.

  (30) On the premise of the inventions of (28) and (29), the light of the light tube may indicate the moving direction of the vehicle determined by the external situation. As the vehicle information, for example, the steering angle of the vehicle / handle is acquired from the OBD information, or the output of the acceleration sensor that detects the acceleration in the lateral direction is acquired, thereby obtaining the vehicle turning direction. Based on the obtained direction, the light state of the light tube is changed to inform the driver of the moving direction of the vehicle.

  For example, when two light tubes are arranged on the left and right as in the embodiment, the one that turns in the same manner as the turn signal of the vehicle blinks and lights up. In addition, both of them are normally lit, and only the person who turns is blinking, or a color different from the normal emission color is emitted.

(31) On the premise of the inventions of (28) to (30), the light of the light tube is preferably shown in an amount determined by the external situation. For example, the remaining fuel information is acquired from the OBD information, and the remaining amount of fuel is displayed. As a display method, for example, the light intensity of the light emitting portions at both ends that emit different colors is changed, and the remaining amount of fuel is represented by the position where both colors intersect. At that time, it is preferable that the upper light emitting section emits white light so that a predetermined emission color corresponding to the remaining fuel extends from the lower side. For example, when there is a lot of remaining fuel, the emission color should be blue, and the emission color should be changed from blue to red as the disappointment fee decreases.
(32) A program of the present invention is a program for causing a computer to realize the function as the on-vehicle electronic device according to any one of (1) to (31).

  According to the present invention, light is emitted from the light tube in a state that can be visually recognized by the driver, so that it can be emitted in a mode that cannot be obtained by the display unit using the display module, and becomes a new output means using visual recognition. .

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. These drawings are used to explain technical features that can be adopted by the present invention. The configuration of the apparatus described is not intended to be limited to that, but merely an illustrative example.

"Basic configuration of automotive electronic devices"
1 and 2 show a configuration of a radar detector which is a preferred embodiment as an in-vehicle electronic device constituting the system of the present invention. The radar detector 1 includes a thin rectangular case 2 and is fixed to a dashboard of a vehicle by using a bracket 3 attached to the lower side of the back side of the case 2.

  A display unit 5 is provided on the front surface of the case 2 (the surface facing the vehicle rear side (driver side)). The display unit 5 is composed of a color TFT liquid crystal display. On the display unit 5, a touch panel 6 for detecting which part of the display unit 5 is touched is provided. Further, a volume adjustment button 7 is disposed on the right side of the front surface of the case 2, and various work buttons 8 are disposed on the left side.

  The right side surface of the case 2 is provided with a card insertion slot 9 for mounting a memory card as a removable recording medium, and a memory card reader 10 is built inside the card insertion slot 9 in the case body 2. By inserting the memory card 11 from the card insertion slot 9, the memory card 11 is attached to the card reader 10. The card reader 10 takes in data stored in the attached memory card 11. More specifically, the data stored in the memory card 11 includes update information such as new alarm target information (position information such as latitude and longitude, type information), and the update information is transmitted via the control unit 18. The data is stored (downloaded) in the database 19 built in the apparatus, and the data is updated.

  The database 19 can be realized by a nonvolatile memory (for example, NAND Flash memory) in the microcomputer of the control unit 18 or externally attached to the microcomputer. Further, the memory card 11 itself may be configured as a part or all of the database 19. The database 19 stores map data and information related to a certain alarm target at the time of shipment, and data and the like regarding the alarm target added thereafter are updated as described above.

  A GPS receiver 13 is disposed in the upper center of the back side of the case 2, and a microwave receiver 14 and a wireless receiver 15 are disposed beside the GPS receiver 13. The GPS receiver 13 receives a GPS signal from a GPS satellite and outputs current position (latitude / longitude) information. The microwave receiver 14 receives a microwave having a predetermined frequency emitted from the velocity measuring device. The wireless receiver 15 receives VHF and UHF band radio waves for traffic control communication. A speaker 16 is built in a predetermined position in the case 2.

  A mini USB connector 12 is disposed below the back side of the case 2. The mini USB connector 12 is for connecting a cigar plug cord (not shown), and can be connected to a cigar socket of the vehicle via the cigar plug cord to receive power supply.

  The control unit 18 is a microcomputer including a CPU, ROM, RAM, nonvolatile memory, I / O, and the like, and is connected to the above-described units as shown in FIG. The control unit 18 creates information to notify the driver based on information input from the various input devices (touch panel 6, GPS receiver 13, microwave receiver 14, wireless receiver 15 and the like) Information is output using an output device (display unit 5, speaker 16, etc.). These basic configurations are basically the same as the conventional ones.

  The functions of the radar detector 1 according to the present embodiment are realized by being stored in the NAND Flash memory of the control unit 18 as firmware executed by the CPU included in the control unit 18 and executed by the CPU included in the control unit 18. Firmware stored in the NAND Flash memory can be updated with new firmware stored in the memory card.

  The main information output from the output device of the radar detector 1 is alarm information for promoting safety to the driver. The alarm information is output in the following cases, for example. The control unit 18 obtains the distance between the alarm target position (latitude and longitude) stored as map information in the database 19 and the current position (latitude and longitude) of the vehicle detected by the GPS receiver 13. When the distance is less than the predetermined distance, alarm information is output from the output device. For example, the control unit 18 outputs alarm information from the output device when the microwave receiver 14 detects a signal corresponding to the microwave in the frequency band emitted from the speed measurement device. Further, for example, when the wireless receiver 15 receives a predetermined wireless radio wave, the control unit 18 outputs alarm information from the output device. The radar detector 1 makes a driver recognize a dangerous place where a traffic accident is likely to occur by outputting alarm information. Thereby, the radar detector 1 can prompt the driver to drive safely. Note that the alarm information described above is an example, and actually, various other alarm information is output to the driver. The alarm information includes, for example, visual information composed of predetermined images / videos / characters to be output to the display unit 5, information using sound / sound output to the speaker 16, and the like.

(Notification using light tube)
The case 2 has a substantially bowl shape that is horizontally long when viewed from the front. The substantially saddle shape referred to in the present embodiment is a shape in which two circles arranged on the left and right sides are connected to each other, and a constricted portion in which the connecting portion is recessed toward the center. In this embodiment, the diameters of the left and right circles are made equal, and the distance from the center in the longitudinal direction to the center of each circle is also made equal. The front surface of the case 2 has a symmetrical shape vertically and horizontally. The display unit 5 has a rectangular shape and is arranged at the center of the front surface of the case 2.

  The light tube 20 is disposed at a predetermined position on the front surface of the case 2. The light tube 20 is disposed along the left and right peripheral edges of the front surface. Each light tube 20 has a circular arc shape, and one end of the light tube 20 is arranged so as to approach the upper side of the display unit 5 and the other end of the light tube 20 is arranged to approach the lower side. The light tube 20 is arranged so as to go around the outside of the volume adjustment button 7 and the work button 8.

  A light emitting unit is connected to each end of the light tube 20. For example, a full color LED 22 is used as the light emitting unit. Light of a predetermined emission color emitted from the full color LED 22 enters the light tube 20 from the end of the light tube 20. A part of this incident light leaks out from the periphery of the light tube 20 while traveling through the light tube. Light is emitted from the entire light tube 20 and shines in a predetermined color along the shape of the light tube 20. Since the light tube 20 is disposed on the front surface of the case 2 facing the driver, the light emitted from the light tube 20 can be visually recognized by the driver.

  Furthermore, the front surface of the case 2 is opened along the outer periphery of the substantially bowl shape, and the transparent cover 33 is attached to the opened portion to close the opening on the front surface. The transparent cover 33 keeps the area facing the display unit 5, the volume adjustment button 7, the work button 8, and the light tube 20 transparent, so that the display object of the display unit 5, light from the light tube 20, and the like can be transmitted. Outputs to the front and outside. Therefore, as described above, the driver can visually recognize the display object on the display unit 5 and the light from the light tube 20. The transparent cover 33 smokes the inner surface of the portion outside the area facing the display unit 5, the volume adjustment button 7, the work button 8, and the light tube 20, thereby making it difficult to see the inside of the case 2.

  FIG. 3 shows a schematic diagram of the light tube 20, the full color LED 22, and the display unit 5. Full-color LEDs 22 are connected to both ends of the light tube 20, respectively. The full-color LED 22 connected to one end of the light tube 20 positioned on the upper side of the display unit 5 is referred to as a first full-color LED 22a, and the full-color LED 22 connected to the other end of the light tube 20 positioned on the lower side of the display unit 5 is a second full-color. LED 22b. In the following description, when it is not necessary to distinguish each of the full-color LEDs, the full-color LEDs 22 are simply referred to collectively, and when distinguished, either the first / second is described. The full color LED 22 is disposed on the back side of the display unit 5. When the driver looks at the radar detector 1 from the front, the full color LED 22 is hidden by the display unit 5.

  The control unit 18 controls the light emission of the first full color LED 22a and the second full color LED 22b. As an example of light emission control, each light emission color is controlled to be different. The light of the first emission color emitted from the first full-color LED 22a enters the light tube 20 from one end of the light tube 20, and a part of the light tube 20 proceeds toward the other end in the light tube 20. The light is emitted from the surroundings to the outside. Accordingly, the first section K1 from the one end of the light tube 20 to a point separated by a predetermined distance shines with the first emission color. On the other hand, the light of the second emission color emitted from the second full-color LED 22b enters the light tube 20 from the other end of the light tube 20, and a part of the light tube proceeds while moving toward the one end in the light tube 20. The light is emitted from around 20 to the outside. Therefore, the second section K2 from the other end of the light tube 20 to a point separated by a predetermined distance shines with the second emission color. Each light incident from both ends of the light tube 20 collides and mixes at a predetermined position in the light tube 20. In the third section K3 where both the lights are mixed, the light shines in an intermediate color between the two emission colors.

  If the first emission color is, for example, red and the second emission color is, for example, blue, the first section K1 is red, the second section K2 is blue, and the third section K3 is purple. The color of light near the boundary between adjacent sections gradually changes. The position of the third section K3 is determined by the difference between the light emission intensity of the first full color LED 22a and the light emission intensity of the second full color LED 22b. When both light emission intensities are equal and there is no light emission intensity difference, the distance from both ends is the same as the central position in the length direction. When the light intensity of the second full color LED 22b is stronger, as shown in FIG. 3 (b), the third section K3 becomes shorter than the one end of the light tube 20, and the first section K1 becomes shorter, and the second full color LED 22b. 3B, the third section K3 is located at one end of the light tube 20, and the first section K1 is shortened. On the contrary, the light intensity of the first full-color LED 22a is shown in FIG. If this is stronger, as shown in FIG. 3C, the third section K3 is located at the other end of the light tube 20, and the second section K2 is shortened. Therefore, for example, the control unit 18 gradually approaches the light intensity difference obtained by subtracting the light intensity of the second full-color LED 22b from the light intensity of the first full-color LED 22a from a large negative value to zero and then a positive value. When the control is performed to increase the position, the position of the third section K3 that shines in the intermediate color moves from one end of the light tube 20 to the other end. With this movement, the region that emits light in the first emission color in the first section K1 gradually extends, and the region that emits light in the second emission color in the second section K2 gradually shrinks.

  The control performed by the control unit 18 such that different colors are emitted is performed such that at least one of hue, saturation, and brightness is different. The color is not limited to the different colors such as red and blue as described above. For example, the color of (255,0,0) when R, G, and B are each expressed in 256 gradations, and (128,0) , 0), even when only the R component is used, the emission color is different even when the value of R is different.

  The control unit 18 performs light emission control on the first full color LED 22a and the second full color LED 22b, for example, when a predetermined alarm condition is satisfied. For example, similarly to outputting the alarm information using the display unit 5 described above, the control unit 18 detects the alarm target position (latitude and longitude) stored as map information in the database 19 and the GPS receiver 13. The distance between the two is obtained from the current position (latitude and longitude) of the vehicle, and when the obtained distance is equal to or less than the predetermined distance, the light emission state of the full-color LED 22 is controlled, and the light tube 20 emits a predetermined color accordingly. To. In addition, for example, the control unit 18 detects when a signal corresponding to a microwave in a frequency band emitted from the speed measurement device is detected by the microwave receiver 14 or when a predetermined radio wave is detected by the wireless receiver 15. Then, the light emission state of the full color LED 22 is controlled so that the light tube 20 shines in a predetermined color.

  Thus, since the light tube 20 shines, it becomes not a point light source like a lamp or an LED light source but a light emitting source having a certain length. Further, unlike a display module, a driver corresponding to the light emission position is not required, and therefore, by arranging the radar detector 1 along the outer periphery of the radar detector 1 as in the present embodiment, display by a conventional display module is performed. It is possible to emit light in a manner that cannot be obtained by the part, and it becomes a new output means utilizing visual recognition. And by arrange | positioning the light tube 20 outside the display part 5, the outer side of the display area of the display part 5 also shines. Therefore, by using the light emitted from the light tube 20 as one of the alarm information, even if the display unit 5 is small, it is more conspicuous, has an impact on the driver, and the surprise effect is enhanced.

(Modification of light emission control)
In the above-described embodiment, the first full-color LED 22a and the second full-color LED 22b have different emission colors, and the light intensity difference is adjusted to perform control for moving the position of the third section K3 that emits light with an intermediate color. The present invention is not limited to this, and various controls are possible. For example, the light intensity difference may be fixed and the emission color of the first full color LED 22a and the second full color LED 22b may be controlled to change.

  The control unit 18 performs control so that, for example, at least one of hue, saturation, and brightness is different. It is not limited to those having different hues such as red and blue, as exemplified in the above-described embodiment. For example, the color of (255, 0, 0) when R, G, and B are each expressed in 256 gradations Even when only the R component is used, such as the color of (128,0,0), different emission colors are obtained even when the value of R is different.

  And the control part 18 is good to control so that at least one luminescent color of 1st full-color LED22a and 2nd full-color LED22b may change with progress of time. By changing the emission color of the full-color LED 22 over time, the state / mode of light emitted from the light tube 20 changes, so for example, it looks like a gradation in which the emission color of the light tube gradually changes, You can make it look like light is flowing.

  The light emission color can be changed by, for example, turning on / off one kind of light emission color, turning on two light emission colors alternately, or combining a predetermined color (for example, red → orange → yellow). (→ green → blue → indigo → purple), and so on, and the values may be switched discretely. For example, the R, G, and B values constituting the three primary colors of light are gradually changed. It may be changed.

  The control for changing each value of R, G, and B constituting the three primary colors of light may be controlled so as to change with a reference pattern set for each value, for example. For the reference pattern, for example, R, G, and B are each changed by a sine wave, and the emission color is changed by appropriately shifting the phase of the reference pattern of each value of R, G, and B, such as 30 degrees and 60 degrees. It is good to perform control to change. By changing each value of R, G, and B, the change in the emission color can be easily controlled, and the change in the emission color can be made rich.

  The reference patterns for the above R, G, and B values may be the same or different. When changing the reference pattern, for example, one is changed by a sine wave, and the other is changed by sweeping with a triangular wave, or the peak value is changed by the same sine wave, or the period is changed. Various aspects can be taken, such as changing. Changing the cycle is preferable because it results in a more complicated change pattern, which is more interesting and impacts the driver.

  Further, it is preferable to change both the emission colors of the first full-color LED 22a and the second full-color LED 22b. In this case, it is preferable that the emission color change patterns of the respective full-color LEDs are shifted in phase by the same pattern. The change pattern is, for example, one in which the emission color changes gradually like a sine wave, a triangular wave, a rectangular wave that alternately switches between two types of emission color, and one type of emission color that is turned on / off (ON / OFF) There are various types, such as a rectangular wave, a combination of predetermined colors (for example, red → orange → yellow → green → blue → indigo → purple). Shifting the phase means, for example, shifting the period of a sine wave or the like by a predetermined angle (for example, 30 degrees, 60 degrees, etc.), shifting the rising timing of a rectangular wave, or changing the start color in the case of a predetermined color combination. It is something to change.

  By changing the emission color of both full-color LEDs, for example, the colors of the first section K1, the second section K2, and the third section K3 of the light tube 20 can be changed over time. Can be impacted, and warnings can be reliably transmitted to the driver. Furthermore, by changing both emission colors, variations in the color and pattern of light emitted from the light tube 20 can be increased, so that the driver can be prevented from getting bored or distracted, and a surprise effect is also expected. it can.

  Moreover, when changing the luminescent color of full color LED, it is good for the control part 18 to control so that it may change with the period which a human can visually recognize. The period which can be visually recognized is good to be 15-20 Hz, for example. In this way, it can be clearly seen that the state of the light emitted from the light tube 20 looks crushed and changes.

  For the control of the emission color of the first full-color LED 22a and the second full-color LED 22b performed by the control unit 18, one may be white / transparent light. In this way, a region of light of a predetermined color extends from the end side of the light tube 20 connected to the full color LED that emits light of a predetermined emission color other than the other white / transparent light. The section of the light tube 20 that shines in a predetermined color is determined by the difference in light intensity between the first full-color LED 22a and the second full-color LED 22b. For example, when the emission color of the first full-color LED 22a is white, a predetermined section (second section K2) on the lower side of the light tube 20 is in a state of shining with a predetermined color.

  In such a form in which one side emits light with white / transparent light, if the control is performed to change the light intensity difference between the two full-color LEDs with the passage of time as in the above-described embodiment, a region that shines in a predetermined color For example, an output operation such as an indicator or a level meter can be performed.

  Moreover, the control part 18 may make the light emission color of both full-color LED the same. When the same emission color is used, light of the same color is emitted from the entire light tube 20 regardless of the light intensity difference between the two full-color LEDs. The light tube 20 increases the amount of light that exits from the bent part and shortens the reach of the light, but the light cannot enter the other end with a single full-color LED by entering light from both sides. Even with a long light tube, the entire light tube 20 can be illuminated.

  In addition, the control for setting the same emission color may change the emission color over time. In this case, when the control is performed to change the emission color of both full-color LEDs to the same color at the same timing, the light tube operates to change its color while shining with the same color as a whole. Moreover, you may make it insert the pattern which makes the light emission color of both full color LED the same in the middle of the change in embodiment mentioned above and various modifications.

(Cooperation / fusion of light tube and display)
The control part 18 is good to control so that the display thing output to the display part 5 and the light radiate | emitted from the light tube 20 may relate. Here, the display object includes, for example, a predetermined picture / motif or a character. By fusing the display unit 5 and the light tube 20, the display area becomes larger than the display screen of the display unit 5. The edges of the display module constituting the display unit 5 do not shine due to the driver or the like. For this reason, even if the size of the display unit 5 is increased, it is difficult to use the entire front surface of the case 2 of the radar detector 1, particularly up to the vicinity of the outer peripheral edge, as the display area. Further, since the front surface of the case 2 faces the driver, various switch buttons (for example, the volume adjustment button 7 and the work button 8) are arranged as one of the user interfaces. The display area of the display unit 5 is narrower than the outer periphery of the radar detector 1. Furthermore, when the shape of the outer peripheral edge of the front surface is a non-rectangular shape including a curved portion like a substantially saddle shape as in the present embodiment, between the peripheral edge of the rectangular display unit 5 and the outer peripheral edge of the radar detector 1. A gap is created.

  On the other hand, if it is the optical tube 20, it can arrange | position to the peripheral edge of the case of a vehicle-mounted electronic device. Therefore, the display object can be expressed using the entire front surface facing the driver of the case. The control related to the display object to be displayed on the display unit 5 and the light emitted from the light tube 20 includes, for example, a technique in which a part of the object expressed by the display object is symbolized and expressed by the light tube 20. For example, as shown in FIG. 4 (a), the character “X” is output to the display unit 5, and both ends of the light tube 20 and the character “X” are continued to express “∞” as a whole. There is. In this way, the display object output to the display unit 5 (for example, the letter “X”) and the light tube emit light so that the display object output to the display unit and the light tube have continuity and a sense of unity. It will be stronger and easier to understand. Moreover, the display thing output to the display part 5 is not restricted to a character. For example, although not illustrated, an arc connecting the upper ends of the left and right light tubes (the portion to which the upper side of the display unit 5 is connected) and the lower ends of the left and right light tubes (of the display unit 5) The goggles are expressed by outputting an arc connecting the lower sides) to the display unit. Although not shown, for example, a picture of a dragon may be output to the display unit 5 as a part of the object, and the tail of the dragon may be symbolized by a light tube. Alternatively, a face picture may be output to the display unit 5 and a light tube may be used as a symbol of the ear.

  Furthermore, the control unit 18 may output a moving image to the display unit 5 and control the light tube light to change in accordance with the movement. For example, a moving image of a creature such as a dragon is output on the display unit, and the light emission state of the light tube 20 that symbolizes the tail of the dragon is changed according to the movement of the direction of the dragon or approaching the front side from the back side. To change.

  Further, as shown in FIG. 4B, the control unit 18 controls the light emission of the first full-color LED 22a and the second full-color LED 22b connected to the left light tube 20, for example, and lowers the region of the third section that emits light in an intermediate color. Is then moved to the upper end, and then “●” indicated by symbol a is output to the display unit 5. The emission color of “●” is the same as the light color of the third section of the light tube 20. Thereby, the light that has moved in the light tube 20 reaches the upper end of the light tube 20 and is emitted into the display unit 5 from there. In addition, the position of “●” output to the display unit 5 moves toward the lower right as shown by the broken line as time passes, and disappears when reaching the lower end of the right light tube 20. Next, the light emission of the first full-color LED 22a and the second full-color LED 22b connected to the right side light tube 20 is controlled, and control is performed to move the region of the third section that shines in the intermediate color from the lower end to the upper end. Thereafter, the control unit 18 outputs a moving image in which “●” is moved obliquely from the upper right to the lower left on the display unit 5. Thereafter, by repeatedly performing such control, it is possible to indicate a state in which light of a predetermined emission color moves along a predetermined locus (for example, an infinite mark). The output of the moving image on the display unit (for example, movement of “●”) and the light in the light tube 20 may not be performed at the same time, and a time lag may be generated.

  In FIGS. 4A and 4B described above and FIGS. 13 to 20 described below, the boundary between the light tube 20 and the display unit 5 describes the cooperation / fusion of the light tube 20 and the display unit 5. It is connected and described for convenience. For example, in FIG. 4A, the upper and lower ends of the letter “X”, which is a display object displayed on the display screen of the display unit 5, are described so as to reach the upper side and the lower side of the display unit 5. It describes in the aspect which continues to the front-end | tip. In practice, for example, as shown in FIG. 5, there may be a region where the display object is not displayed in the region above the upper side of the display unit 5 or the region below the lower side of the display unit 5. Further, even if the display unit 5 of a type that does not have an area that is not displayed on the upper side or the lower side of the upper side is used, for example, a color LED or the like arranged on the back side of the display unit 5 by bending the tip of the light tube 20 The part which the light tube 20 shines may leave | separate from the periphery of the display part 5 by taking the form connected to a light emission part. However, ideally, it is desirable to eliminate the boundary as shown in FIGS. 4 and 13 to 20.

  FIG. 13 and subsequent figures show still another variation of notification in which the display unit 5 and the light tube 20 are fused. FIG. 13 represents discharge. In FIG. 13A, the control unit 18 causes the full color LED 22 connected to both ends of the light tube 20 to emit light in a predetermined blue color so that the entire light tube 20 shines in blue. Furthermore, the control unit 18 outputs X that appears in blue on the display unit 5. As shown in FIG. 4A, both ends of the light tube 20 and the letter X output to the display unit 5 are connected. Further, the control unit 18 draws the discharge so that light travels around the straight line constituting “X”. The portion of the discharge around the straight line constituting “X” may be a still image, but it is preferable to create a moving image as if it is discharging / light is running because it gives a sense of realism. Further, it is preferable to output a discharge sound such as “buzz” or “buzz” from the speaker 16 in accordance with the discharge operation. In addition, it is better to output lightning sound and lightning sound as an image of lightning.

  FIG. 13B shows the discharge portion more strongly than the portion of the letter “X”, compared to FIG. 13A. That is, the discharge amount / volume is increased, the discharge is drawn overlapping the character portion, and the emission intensity of the discharge portion is also drawn strongly. For example, if the color of the character portion “X” is lightened, the discharge portion may be more conspicuous.

  In FIG. 13C, the character “X” is eliminated as information to be output to the display unit 5. The control unit 18 discharges the upper end of the left light tube 20 and the lower end of the right light tube 20, and the lower end of the left light tube 20 and the right light tube 20. Draw the discharge connecting the upper edges. It is preferable to use a moving image as a moving image because it gives a more realistic feeling.

  FIG. 14A represents the flame / flame. The control unit 18 causes the full color LED 22 connected to both ends of the light tube 20 to emit light in a predetermined red color so that the entire light tube 20 shines red. Further, the control unit 18 outputs on the display unit 5 the red or orange X. As shown in FIG. 4A, both ends of the light tube 20 and the letter X output to the display unit 5 are connected. Further, the control unit 18 outputs a flame that swings around a straight line that constitutes “X”. As in the case of the above discharge, the flame portion may be a still image, but it is preferable because a realistic feeling can be obtained by showing a moving image of the actual movement of the flame. In the image of walking farming, the color may be red, warm, or red / orange / pink, but may be blue / cold.

  FIG. 14B represents goggles. In the figure, the color of the light tube 20 and the color output to the display unit 5 are the same color (for example, red), but may be different or may change with the passage of time.

  FIG. 15 represents a rotating circle. 13 and 14, the left and right light tubes 20 are connected by a motif that is output to the display unit 5, but in the example illustrated in FIG. 15, each light tube 20 represents a separate circle. In other words, a single circle appears by connecting the upper end and the lower end of the left light tube 20 with an arc drawn in the left region of the display unit 5. Similarly, another circle appears by connecting the upper end and the lower end of the right light tube 20 with an arc drawn in the right region of the display unit 5.

  Then, the control unit 18 changes the emission color and emission intensity of the full-color LED 20 connected to both ends of one light tube 20, so that the entire light tube 20 shines or a part of the light tube 20 does not emit light from one end to the other. And control to move towards. The arc drawn on the display unit 5 is changed according to the state of the light tube. That is, as shown in FIG. 15 (a), the upper arc is cut off, or as shown in FIG. 15 (b), the upper end of the light tube 20 is connected to the lower end. As shown in FIG. 15 (c), a circular arc with the lower part cut off is used. As a result, as shown in FIG. 15, a mode in which an arc having a predetermined length rotates is output.

  In addition, the control unit 18 emits the entire left and right light tubes 20 and outputs so as to draw two predetermined arcs in the left and right areas of the display unit 5, so that two circles are arranged side by side. You can also

  Moreover, the control part 18 may make the color of a right and left circle the same, or may make it different. Further, in the example shown in FIG. 15, the color of one circle (arc) is the same color / single color, but is not limited thereto. For example, it is preferable that the control unit 18 changes the emission color of the full-color LED 22 with the passage of time so that the emission color of the arc on one side changes with the passage of time. In particular, it is preferable to use an arc that draws a gradation portion in which the color gradually changes in one arc as an arc that draws on the display unit 5, because the emission color of the full-color LED 22 connected to one light tube 20 can be easily controlled.

  For example, in FIG. 16A, the full color LED 22b connected to the lower side of the light tube 20 outputs red, the full color LED 22a connected to the upper side of the light tube 20 outputs a transparent color, and the light intensity is the same as that of the upper full color LED 22a. Weaken. As a result, the light tube 20 glows red from the lower side to the middle, and the upper side is in a transparent (non-lighting) state. The control unit 18 causes the color of the arc output to the display unit 5 to gradually change from yellow to green as the lower side goes red and goes up.

  Next, the full color LED 22b connected to the lower side of the light tube 20 outputs red, the full color LED 22a connected to the upper side of the light tube 20 outputs green, and the light intensity increases the upper full color LED 22a. As a result, as shown in FIG. 16B, the light tube 20 shines red from the lower side to the middle, glows green from the upper side to the middle, and further the green color region is longer. Become. At this time, the state of the color of the arc output to the display unit 5 is the same as that in FIG.

  Further, the full color LED 22b connected to the lower side of the light tube 20 outputs green, the full color LED 22a connected to the upper side of the light tube 20 outputs a transparent color, and the light intensity weakens the upper full color LED 22a. Thereby, as shown in FIG.16 (c), the light tube 20 shines green from the lower side to the middle, and becomes transparent (it does not shine) the upper side. The control part 18 makes the color of the circular arc output to the display part 5 into a mode in which the lower side is green and colorless (does not shine) from the middle.

  The left arc rotates counterclockwise and the right arc rotates clockwise. Therefore, in the state of FIG. 16A, the left arc rotates with the portion displayed in the display unit 5 as the head.

As a result, in FIG. 16A, almost the entire arc is red, and one tip is changed from yellow to green. That is, when paying attention to the rotation direction, the tip is green and gradually changes from yellow to red, and most of the area of the arc is red. As time passes, almost the entire arc is green as shown in FIG. 16B, and the region on the rear side in the rotational direction changes from yellow to red. Further, as time passes, the entire arc turns green as shown in FIG.
In this way, the arc changes smoothly from red to green while rotating. After this, if the control is sequentially changed from different colors such as green to blue, it may be colorful.

  FIG. 17 represents a state in which a dragon is flying in the sky. The light tube 20 schematically represents the body of the dragon and represents it as a symbol, and the display unit 5 draws and outputs the body of the dragon, such as the head and trunk. By changing the length of the lighted portion of the light tube 20, the state where the dragon is moving and flying is expressed. For example, the dragon moves through the left side light tube 20 from the bottom to the top, exits from the upper end of the left side light tube 20, moves toward the lower right side, and moves to the right side. Enters the lower end of the light tube 20. Further, it moves upward and passes through the right side light tube 20, exits from the upper end of the right side light tube 20, moves toward the lower left, and enters the lower end of the left side light tube 20. Such an operation is repeated.

  Specifically, in FIG. 17A, the full color LED 22a connected to the upper side of the left light tube 20 outputs a predetermined color (for example, green), and the full color LED 22b connected to the lower side of the left light tube 20 is A transparent color is output, and the light intensity is the same or the upper full-color LED 22a is strengthened. Thereby, the light tube 20 shines in green from the upper side to the middle, and the lower side is in a transparent (not shining) state. Also, the two full color LEDs connected to the right light tube 20 are turned off. Further, the control unit 18 outputs a picture of the dragon's head and body on the display unit 5 in a downward state from the upper left to the lower right. As time passes, a moving image that gradually moves the head position downward is output, and the light intensity of the full-color LED 22a connected to the upper side of the left light tube 20 is gradually reduced gradually. The area of the tube 20 that glows green is shortened.

  FIG. 17B shows a state where the dragon moving toward the lower right has entered the right light tube 20. The light of the light tube 20 symbolizes the head of the dragon and the body that follows it. In this state, the full color LED 22b connected to the lower side of the right light tube 20 outputs a predetermined color (for example, green), the full color LED 22a connected to the upper side of the right light tube 20 outputs a transparent color, and the light intensity Initially, the upper full-color LED 22a is strengthened, the difference is gradually reduced, and then the upper full-color LED 22a is weakened. A green light emitting portion in the right light tube 20 that symbolizes the head of the dragon gradually extends upward from below. Further, the control unit 18 outputs a picture of the dragon body on the display unit 5 in a downward state from the upper left to the lower right.

  FIG. 17C shows a state in which the dragon that has moved in the right light tube 20 exits from the upper end of the right light tube 20 and moves toward the lower left. In this state, the operation opposite to that shown in FIG. Although not shown in the figure, after that, the dragon moving toward the lower left enters the light tube 20 on the left side (in a state where the left and right sides of FIG. 17B are reversed), and the left side as shown in FIG. The state of coming out again from the upper side of the light tube 20 is repeated.

  FIG. 18 represents a sound wave. For example, all the full-color LEDs are initially turned off, and the control unit 18 draws a “circle” in the center of the display unit 5 and “arcs” on both the left and right sides (FIG. 18A). The color of this circle and arc is, for example, red. Next, the display unit 5 gradually increases the arcs to be drawn on the left and right sides of the “circle”, and expresses how the sound waves are transmitted from the center toward the outside.

  Further, the full color LEDs connected to the left and right light tubes 20 are caused to emit light in a predetermined color (for example, red). Initially, by reducing the light intensity, red light is emitted in a short region from the upper and lower ends of the light tube 20 as shown in FIG.

  Thereafter, the light emission intensity of the full-color LED is gradually increased, and finally the entire light tube 20 emits light in a predetermined color (for example, red) as shown in FIG. Thereafter, the full-color LED is turned off, and the output of the display unit 5 is once turned off, and control is performed so as to output from the original “circle”.

  FIG. 19 represents a traffic light. One circle is represented by the left light tube 20 and an arc drawn on the display unit 5 (connecting both ends of the left light tube 20), and another circle is represented by a circle / arc drawn at the center of the display unit 5. Then, by expressing one circle by the right light tube 20 and an arc drawn on the display unit 5 (connecting both ends of the right light tube 20), a total of three circles are represented. Since it is a traffic light, the left circle glows green, the center circle glows yellow, and the right circle glows red. Further, these three circles may shine simultaneously, or may shine one by one as shown in FIG. Further, each circle may shine all at once and display the circle, or may be an arc as shown. In the case of an arc, the issue area should gradually change to represent a circle. In FIG. 19, the emission color is a single color, but it may be changed gradually.

  FIG. 20 shows a waveform. In the display part 5, the waveform which vibrates is shown, and the state where the waveform is advancing is shown by making the right and left light tubes 20 light appropriately. For example, in FIG. 20A, the light tube does not emit light and outputs a waveform to the display unit 5. In this state, the right end of the waveform is close to the upper end of the right light tube. The color of the wave output to the display unit 5 is, for example, red.

  When the waveform output to the display unit 5 advances from this state (here, the wave advances to the right), the light advances in the right side light tube 20 (the red region gradually extends downward from the upper end). Then, light emission on the upper end side is suppressed, and a waveform connected from the lower region of the light tube 20 to the display unit 5 is displayed as shown in Fig. 20B. As part.

  Thereafter, as shown in FIG. 20B, a waveform signal is output from the lower end of the right light tube 20, and the display unit 5 is enlarged toward the left. Furthermore, as shown in FIG. 20C, the waveform signal enters from the bottom of the left side light tube 20, and is finally carried out from the top side of the light tube 20.

(Alarm variation)
As in the above-described embodiment, the control unit 18 uses the light emitted from the light tube as one of the visual information when the alarm condition is satisfied, so that there is no display unit or there is a display unit. As a result, it is more conspicuous, has an impact on the driver, and increases the surprise effect. By using such a light tube for notification of a new alarm, the driver can be notified of the alarm more reliably.

  The control unit 18 constituting the alarm means may change the light emission state of the first full-color LED 22a and the second full-color LED 22b according to the type of the alarm target, and change the state of the light emitted from the light tube 20. Changing the light emission state includes various things such as changing the light emission color, changing the light intensity of the light emission color, and changing the blinking state. The types of alarm targets may be classified according to the urgency level (importance level), for example. The driver can recognize the type of the alarm target based on the state of the light emitted from the light tube 20. In the case of the type having the display unit 5, when the alarm information is output, the one having the function of indicating the target of the color corresponding to the type of the alarm target at the position of the alarm target, and the color and display of the light emitted from the light tube It may be the same as the target color output to the unit 5.

  In addition, for example, in the case of a highly urgent alarm condition, the control unit 18 may perform control to increase the speed at which the light intensity difference between the first full-color LED 22a and the second full-color LED 22b is changed. In this way, the position of the intermediate color and the length / section shining with the first light emission color and the second light emission color may change quickly, and the urgency may be more conveyed to the driver. The alarm information output to the display unit 5 and the alarm information using the light tube 20 may be operated in synchronism, or only one of them may be operated.

  In the type having the display unit as in the above-described embodiment, the control unit 18 issues an alarm in which the display unit 5 and the light tube 20 are fused when a predetermined plurality of predetermined alarm conditions are satisfied. It is good to make it. The predetermined plurality of alarm conditions include, for example, alarm conditions based on position information such as the relative positional relationship between the position of the alarm target stored as map information in the database 19 and the current position information of the vehicle being a predetermined setting condition, speed, There are some which satisfy different types of alarm conditions such as alarm conditions based on predetermined radio wave reception such as reception of microwaves in a frequency band emitted from the measuring device by the microwave receiver 14. As a specific example satisfying the different types of alarm conditions, for example, when the alarm target is a speed measurement device and the alarm condition based on the position information is satisfied, a microwave of a frequency band emitted from the speed measurement device is used. In some cases, the alarm condition based on reception and radio wave reception is satisfied at the same time.

  In addition, when a plurality of alarm conditions are satisfied, there are cases where a plurality of alarm conditions of the same type are satisfied at different times. For example, the alarm condition is the alarm condition based on the position information as described above, and the relative positional relationship with the same alarm target is the first distance (for example, 2000 m), the second distance (for example, 1000 m) shorter than the first distance, the second Assuming that the alarm condition based on the position information is satisfied when the distance is a third distance shorter than the distance (for example, 500 m), for example, the first distance → second distance → third Sometimes distances are met in order.

  Furthermore, it is further preferable that both a case where a plurality of types of the above-described alarm conditions are satisfied and a case where a plurality of the same types of alarm conditions are satisfied at different times are provided. For example, it is assumed that when a microwave having a predetermined frequency is received and a first distance → second distance → third distance is satisfied in order, a plurality of specific alarm conditions are satisfied.

  By issuing a combined alarm when a plurality of specific alarm conditions are satisfied, the generation of such an integrated alarm is reduced. Therefore, since the surprise performance when such a combined warning occurs is high and the impact given to the driver is increased, the driver can be notified of the warning more reliably.

  The microwave reception condition may be, for example, that the microwave is received at each position when the first distance, the second distance, and the third distance are satisfied. By doing so, it is possible to reduce the occurrence of a plurality of specific alarm conditions and to reduce the chance of occurrence.

  In the case where the predetermined plural alarm conditions are not satisfied, it is preferable not to issue an alarm in which the display unit 5 and the light tube 20 are fused. For example, when a plurality of predetermined alarm conditions are not satisfied, but other alarm conditions are satisfied, an alarm is issued by either the display unit 5 or the light tube 20, and a display is displayed when the predetermined plurality of alarm conditions are satisfied. It is preferable to issue an alarm in which the unit 5 and the light tube 20 are fused. Thereby, the alarm which the display part 5 and the light tube 20 united becomes a special alarm position.

  The case where a plurality of predetermined alarm conditions are not satisfied is, for example, that an alarm target suddenly appears in front of the traveling direction of the vehicle due to a change in the course of the vehicle and starts approaching from a state where the relative distance is shorter than 2000 m. If the second distance → third distance is satisfied in order without satisfying the first distance condition, or if the third distance is satisfied from the third distance, even if microwaves are received when the conditions for each distance are satisfied The multiple alarm conditions are not met. Even if the position conditions of the first distance, the second distance, and the third distance are satisfied in order, even if the microwave is not received, a plurality of predetermined alarm conditions are not satisfied. In these cases, a warning that the display unit 5 and the light tube 20 are fused is not performed. For example, when a condition for each distance is satisfied, a notification for outputting a message to notify the passage of the distance to the display unit 5 is provided. Do.

(Other notifications)
In the embodiment and the modification described above, the light emitted from the light tube 20 is used to notify an alarm. However, the present invention is not limited to this, and provides various information and exhibits a healing effect. Or have a surprise effect.

  For example, it may be used for reporting an external situation other than an alarm. For example, the control unit 18 may control the light emission of the full-color LED 20 based on the acquired external situation. The external situation includes, for example, vehicle information. The vehicle information may be obtained from OBD information acquired through the OBD adapter 21, for example. Specifically, for example, the control unit 18 obtains the turning direction of the vehicle from the steering angle of the vehicle / handle acquired as one of the OBD information, and based on the obtained direction, the full-color LED 22 connected to the light tube in the turning direction. Light emission is controlled, and the light of the light tube in the bending direction blinks or changes the color of the light. Thereby, it operates like a turn signal of a vehicle. The turning direction is not limited to the OBD information. For example, the output of the acceleration sensor may be acquired, and the turning direction may be detected from the sensor output value.

  Further, the control unit 18 acquires the remaining fuel information from the OBD information, and changes the light emission condition of the full color LED 22 according to the remaining amount of fuel. For example, control is performed such that when the remaining fuel is above a certain level, light is emitted in a blue color, and when the disappointment fee is below a reference value, light is emitted in a red color. The emission color may be switched between two colors, or multiple colors are switched in sequence, and the red system becomes stronger as the disappointment fee decreases, so that the fuel is gradually decreasing. good.

  Further, the control unit 18 controls the first full-color LED 22a to emit light in white / transparent color, appropriately changes the emission color of the second full-color LED 22b, and increases the light intensity of the second full-color LED 22b as the remaining fuel increases. To do. If it does in this way, the area | region (2nd area) of the light emitted from the lower end side of a light tube will become short as the remaining fuel reduces. The longer the shining part, the more remaining fuel, and the shorter, the less disappointment fee.

  Further, the control unit 18 obtains the vehicle speed from the GPS signal, the OBD information, and the like, and controls the light emission state of the full color LED 22 according to the vehicle speed. Control is performed to change the emission color according to the speed, or to change the light intensity difference between the first full-color LED 22a and the second full-color LED 22b according to the speed.

(Detailed structural embodiment)
A more detailed structure of the radar detector 1 will be described with reference to FIG. 1 and FIGS. As described above, the case 2 has a bowl shape when viewed from the front. In this embodiment, the front case 31 and the rear case 32 divided in the front-rear direction are abutted so as to contact each other's joint surfaces and screwed together to be integrated. The front case 31 and the rear case 32 are each formed of synthetic resin or the like, and the color thereof is black.

  As shown in FIG. 7 and the like, the front case 31 includes a substantially bowl-shaped side wall 31a as viewed from the front, and both front and rear surfaces thereof are open. The rear end surface of the side wall 31 a becomes a joint surface with the rear case 32. On the inner peripheral surface in the vicinity of the front end side of the side wall 31a, a flange portion 31b protruding inward is formed over the entire periphery. A transparent cover 33 is attached to the front opening of the front case 31 (see FIG. 1A, etc.). The peripheral edge of the transparent cover 33 attached to the opening part contacts the collar part 31b. Therefore, the transparent cover 33 and the front case 31 are bonded and fixed using, for example, an adhesive. Further, a through hole may be provided at an appropriate position of the flange portion 31b, a projecting piece inserted into the through hole may be provided on the rear surface of the transparent cover 33, and the projecting piece may be inserted into the through hole and connected.

  An arc-shaped groove portion 31c is provided at a predetermined position on the front surface of the flange portion 31b. The positions where the grooves 31c are provided are arranged on the left and right sides and along the outer peripheral edge of the front case 31. Both ends of the groove 31c are connected to the inner peripheral edge of the flange 31b. The light tube 20 is inserted and set in the groove 31c. The light tube 20 maintains a posture curved in an arc shape along the groove 31c. The total length of the light tube 20 is longer than the total length of the groove portion 31c, and one end of the light tube 20 includes a straight portion 20a arranged in parallel along the upper side of the display portion 5, and a further tip of the straight portion 20a. It has a side tip portion 20b. Similarly, the other end of the light tube 20 has a straight portion 20a arranged in parallel along the lower side of the display unit 5, and a distal end portion 20b on the further distal side of the straight portion 20a.

  As shown in FIG. 5, the display unit 5 includes a driver 5a or the like outside the left side of the display module constituting the display area. The light tube 20 on the left side is arranged so as to go around the outside of the driver 5a and the volume adjustment button 7. Therefore, the outside of the driver 5 a that does not become a display area can be illuminated using the light tube 20. Furthermore, in this embodiment, the driver 5a is on the left side of the display unit 5, and one end of the light tube 20 is arranged on the upper side of the display unit 5 and the other end of the light tube 20 is arranged on the lower side of the display unit 5. The connection between the display object output to the display unit 5 and the light tube 20 can be improved.

  As described above, the front case 31 is made of a black synthetic resin or the like, and the inside of the groove 31c is also black. Since the back surface of the groove portion 31c is located on the rear side of the light tube 20 and becomes a black background, the color of the light emitted from the light tube 20 looks beautiful. For example, the driver can visually recognize the light from the light tube 20 even if light entering from outside the vehicle such as during the daytime or on the west is irradiated on the front surface of the radar detector 1. Further, since the light tube 20 is housed in the concave groove 31c, both side surfaces of the black groove portion 31c are located also on the side surface side of the light tube 20, so that even if the driver views the light tube 20 from an oblique direction. The light emitted from the light tube 20 looks beautiful.

  As described above, the linear portion 20 a on one end side of the light tube 20 is arranged along the upper side of the display unit 5, and the linear portion 20 a on the other end side of the light tube 20 is arranged along the lower side of the display unit 5. (See FIG. 5 etc.). Then, as shown in FIG. 1A and the like, when the transparent cover 3 is attached to the front case 31, the linear portion 20a and the arcuate end adjacent thereto are hidden, and only the arcuate portion of the light tube 20 is visible. It becomes possible. Since more light leaks to the outside from the bent portion of the light tube 20, the amount of light emitted to the outside from the boundary position P1 between the straight portion 20a and the arcuate portion 20c of the light tube 20 in FIG. The amount of light emitted from the arcuate portion 20c to the outside increases. Therefore, the area of the transparent cover 33 facing the ends of the straight line portion 20a and the arcuate portion 20c including the boundary position P1 is smoked so that light is not transmitted or is difficult to transmit. Thereby, the light emitted from the arc-shaped portion 20c of the light tube 20 becomes visible to the driver.

  As shown in FIGS. 8, 9, etc., the arcuate portion 20 c of the light tube 20 is located further forward than the surface of the first substrate 35. The tip portion 20 b of the light tube 20 is routed to the back side of the first substrate 35. The first full-color LED 22a and the second full-color LED 22b are mounted at predetermined positions on the back surface of the first substrate 35. The end surface of the distal end portion 20b of the light tube 20 faces the light emitting surface of the first full-color LED 22a and the second full-color LED 22b, and connects the two. Thereby, the light emitted from each of the full-color LEDs 22a and 22b enters the light tube 20 from the end face of the distal end portion 20b of the opposing light tube 20.

  By hiding the first full color LED 22a and the second full color LED 22b on the back surface of the first substrate 35, only the light emitted from the light tube 20 can be visually recognized from the outside. The display unit 5 is mounted on the surface of the first substrate 35. By disposing the first full-color LED 22a and the second full-color LED 22b on the back surface of the first substrate 35, the light tube 20 can be disposed close to the periphery of the display unit 5, the light emitted from the light tube, and the display unit 5 Control that makes it easy to understand the continuity and relevance with the display object that is output to. Further, the light tube 20 can be arranged in a narrow space. Therefore, the light tube 20 can be arranged in a narrow space between the upper and lower sides of the display unit 5 and the upper and lower outer peripheral edges of the case 2 of the radar detector 1.

  In this embodiment, the light emission directions of the first full color LED 22a and the second full color LED 22b are parallel to the first substrate 35 on which the LEDs are mounted. This can be realized by using a right angle type LED. A right angle type LED emits light in a direction bent 90 degrees with respect to a pin mounted on a substrate. For output, for example, a high-brightness LED of about 1000 mcd (candela) is used.

  A locking portion 40 that fixes the distal end portion 20b of the light tube 20 is mounted at a predetermined position on the back surface of the first substrate 35. As shown in an enlarged view in FIG. 10, the locking portion 40 includes an elongated belt-like base 40 a and a pair of projecting pieces 40 b erected on both long sides of the base 40 a. The distance between the pair of projecting pieces 40b is such that the open side away from the base 40a is narrower. The locking portion 40 is integrally formed using elastic metal, resin, or the like. The projecting piece 40b functions like a leaf spring. The base 40 a is fixed at a predetermined position on the first substrate 35. Further, the minimum distance d (see FIG. 10C) on the open side of the pair of projecting pieces 40b is narrower than the diameter of the light tube 20. Thereby, by pushing the tip portion 20b of the light tube 20 toward the base 40a from the opening side of the locking portion 20, the tip portion 20b is inserted between the pair of projecting pieces 40b, and due to the elastic force of the projecting piece 40b. It is fixed and placed with appropriate force. When the light tube 20 is attached to the locking portion 40, the light tube 20 can be fixed and positioning of the end portion of the light tube 20 and the light emission portion of each LED is completed. In this embodiment, by providing two pairs of protruding pieces 40b in the longitudinal direction, the optical tube 20 can be firmly fixed, and the direction of the distal end portion 20b of the optical tube 20 is also parallel to the base 40a so that correct positioning is achieved. Yes. Moreover, since the latching | locking part 40 was used as the one-touch-type clip, the light tube 20 can also be set easily.

  For example, the locking portion 40 may be formed by bending a single metal plate. FIG. 10E shows an example of a developed state of the metal plate 40 ′. The metal plate 40 ′ has a shape in which the protruding pieces 40 b are continuous and protrude outward at two predetermined positions on both long sides of the elongated base 40 a. The protruding piece 40b is substantially L-shaped, and has a short width w1 on the connection side of the base 40a and a long width w2 on the non-connection side tip. Further, the locking portion 40 is manufactured by bending the metal plate 40 'in an appropriate direction at the portions of the folding lines L1 and L2. At this time, by shortening the width w1 on the connection side of the projecting piece 40b, the length of the fold line L1 when rising from the base 40a, that is, the portion to be folded is shortened, so that it can be easily folded with a small force. So good. In addition, the light tube can be firmly held by increasing the width w2 of the tip of the protruding piece 40b.

  The width w4 of the end portion 40c located at both ends in the longitudinal direction of the base 40a is longer than the width w3 between the fold lines L1 when the protruding piece 40b is raised. Thereby, the contact area of the latching | locking part 40 to the 1st board | substrate 35 can be enlarged, and the latching | locking part 40 can be firmly fixed to the 1st board | substrate 35 by soldering.

  The first substrate 35 is a substrate for light emission / display functions, such as the display unit 5, the light tube 20, and both full-color LEDs 22a and 20b. For example, the LCD constituting the display unit 5 and a microcomputer for controlling the LCD. Etc. In this embodiment, the memory card reader 10 and the speaker 16 are also mounted on the back surface of the first substrate 35.

  As shown in FIG. 9 and the like, a second substrate 36 is disposed on the back side of the first substrate 35. Thereby, the 1st board | substrate 35 and the 2nd board | substrate 36 will be in the state piled up along the driver | operator's visual recognition direction. The second substrate 36 is a substrate on which the basic functions of the radar detector 1 are mounted, for example. On the second substrate 36, the microwave receiver 14 is disposed at the center upper position on the back surface opposite to the first substrate 35, and the GPS receiver 13 and the wireless receiver 15 are disposed on both the left and right sides of the microwave receiver 14. Place. Various electronic devices / parts such as the control unit 18 and the database 19 are also mounted on the second substrate 36 at appropriate positions.

(Installation of light shielding mechanism)
FIG. 11 shows a cross-sectional view of the radar detector 1 cut at the central portion. As shown in FIG. 11A, the speaker 16 is arranged at a lower portion in the center portion of the radar detector 1 in the longitudinal direction. At a predetermined position below the outer peripheral surface of the rear case 32, a hole penetrating inward and outward is provided as a speaker port 32a. The speaker port 32a is located in the vicinity of the speaker 16, and the sound output from the speaker 16 is transmitted to the outside of the radar detector 1 through the speaker port 32a.

  FIG.11 (b) has shown the state which removed the speaker 16 from Fig.11 (a). An area of the second substrate 36 in which the speaker 16 is disposed is a notch 36a. In a state where the speaker 16 is detached, the space on the front surface side (the upper side in FIG. 11) of the second substrate 36 and the space on the back surface side of the second substrate 36 are connected via the notch 36 a. The full color LED 22 connected to the first substrate is located in the space on the front surface side of the second substrate 36, and the speaker port 32 a is located on the back surface side of the second substrate 36. Further, most of the light from the full-color LED 22 is injected into the inside from the end face of the light tube 20, but a part of the light may be emitted to the space on the back surface of the second substrate 36 without being injected. In such a case, in the state of FIG. 16B in which the speaker 16 does not exist, a part of the light emitted from the full color LED 22 may reach the speaker opening 32a and leak out of the radar detector 1. In the present embodiment, since the light leakage path from the speaker 16 is blocked, it is possible to prevent the speaker port 32a from shining (light leaking from the speaker port). The speaker 16 functions as a light shielding member.

  As shown in FIGS. 7 and 12, etc., a flange 31b protruding inward is formed on the inner peripheral surface in the vicinity of the front end side of the side wall 31a of the front case 31 over the entire periphery. The inner peripheral surface of the flange 31b constitutes each side of a predetermined rectangle, and an opening 31d made of the rectangle is provided on the front side of the front case 31. The display unit 5 is disposed in the opening 31d. The collar portion 31b in the left region of the front case 31 is disposed up to a position that covers the upper side of the work button 8, and a cutout portion 31e is formed at an upper facing portion of the work button 8. The flange 31b in the right region of the front case 31 is disposed up to a position covering the upper side of the volume adjustment button 7, and a circular through hole 31e is formed at an upper facing portion of the volume adjustment button 7. A cylindrical tube wall 31f is formed on the back surface side of the flange portion 31b along the periphery of the through hole 31e. The tip of the cylindrical wall 31f is close to or in contact with the surface of the first substrate 35. The light emitting diode 50 is disposed in a predetermined position of the first substrate 35 and in the cylindrical wall 31f. The light emitted from the light emitting diode 50 is applied to the back surface of the transparent cover 33 through the through hole 31e, and the volume adjustment button 7 is illuminated. Therefore, the location of the volume adjustment button 7 can be easily understood even at night.

  In the present embodiment, by providing the cylindrical wall 31f, the light from the light emitting diode 50 travels through the cylindrical wall 31f and irradiates the volume adjustment button 7, but in the space on the opening 31d side where the display unit 5 is disposed. Leakage is prevented. In addition, the cylindrical portion 31f prevents light from entering from the outside of the cylindrical portion 31f, and the volume adjustment button 7 is illuminated by the light from the light emitting diode 50. That is, the cylindrical wall 31f functions as a light shielding member.

  Further, the full color LED 20 is installed on the back side of the first substrate 35, and the first substrate 35 is arranged over almost the entire surface in the case 2. Therefore, even if there is light emitted from the full-color LED 22 on the back side of the first substrate without being injected into the light tube 20, the light is transmitted from the outer periphery of the first substrate 35 to the first.
