Description

The present invention relates to an information display system.

Conventionally, information display systems acquire information about driving and display the information on a display screen, such as navigation devices mounted on vehicles such as automobiles and bicycles, and microwave detectors (radar detectors) mounted on automobiles. Electronic devices such as electronic devices for displaying, or electronic devices such as vehicle audio devices for displaying visual information content on a display screen such as terrestrial digital TV, CD, DVD, and the like.
Patent Documents 1 and 2 are cited as examples of conventional electronic devices such as these. The electronic equipment disclosed in Patent Document 1 is a head-up display (HUD) arranged on the dashboard of the vehicle interior. As shown in FIGS. 1 to 5 of Patent Document 1, this HUD includes a combiner 3 made of transparent resin and projects image light containing information from a display 2 disposed in a case 1 onto the combiner 3 to indirectly It is a configuration that allows the user to visually check the
However, in the HUD as in Patent Document 1, the user is allowed to indirectly view the display 2 through the combiner 3. Although the projected image light can be seen sufficiently, the image light projected onto the combiner 3 may not be sufficient relative to the outside light during the daytime when the ambient light intensity is high, and the display content becomes difficult to see. There is a possibility that

On the other hand, Patent Literature 2 discloses a display 601 having a display screen 602 arranged on a dashboard in an automobile, as shown in FIG. 6 thereof. In an information display system having a display unit that is directly viewed by the user, as in Patent Document 2, the user can directly view the display unit, so even in the daytime when the weather is fine, the HUD of Patent Document 1 is used. It's not hard to see.
However, in electronic devices such as Patent Document 2, in which the display unit is directly viewed, it is generally easier to see than the HUD during the daytime when the weather is fine, but it is rather too bright at night or in a dark state such as rainy weather as described above. You will feel dazzling.
For this reason, electronic devices equipped with both a display screen for indirectly viewing the display screen as in Patent Document 1 and a display screen for directly viewing the display screen as in Patent Document 2 are installed, depending on the situation. Although it is conceivable to configure one of the display screens so that the user can see it, if both screens are provided, the overall size increases, and depending on the installation location, the user's field of vision may be obstructed. . Moreover, providing different display screens poses problems such as increasing costs in the future.
SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide an information display device provided with a display screen that can be viewed indirectly or directly by a user on a single display screen. It is to provide a system.

In order to achieve the above object, as means 1, the display screen is reflected by a reflector to allow the user to indirectly view the display content, and the display content of the display screen is directly viewed by the user. It is preferable to have a second display mode.
With such a configuration, the user can recognize the information displayed on the display screen in an easy-to-see display mode according to the brightness of the surroundings.
The human eye is designed so that when the surroundings are dark, the pupil opens to let in more light so that objects can be seen even when the amount of light is low. On the other hand, when there is a lot of light, such as in bright daytime, the pupil constricts and suppresses the light that is taken in. If the brightness of the display screen is the same, the brightness is relatively attenuated when viewed indirectly rather than when viewed directly. Therefore, it is easier for the user to see the displayed content indirectly when the pupil is dilated and the display is dark, and when the pupil is constricted and the display is bright. leads to
The display screen may be a dot matrix display such as an organic EL display or a liquid crystal display (LCD) that emits light by itself or by backlight. In general, HUDs often require a high-luminance display method so that the amount of light is reduced due to reflection and that the HUD can be viewed in the daytime. However, according to the configuration of means 1, the first display mode in which the display screen is reflected by the reflector to allow the user to indirectly see the display content is, for example, a situation in which the surroundings are dark such that a headlight is required. For example, it may be limited to night time, so high brightness is not required. On the other hand, the second display mode, in which the user can directly see the display contents of the display screen, can take a bright environment such as daytime. can. In addition, a dot matrix display such as an inexpensive general-purpose liquid crystal can be used, which contributes to cost reduction. In addition, high resolution and clear display can be maintained even when viewed directly.
In addition, "surrounding brightness" is influenced by the surrounding environment. For example, it can be said that a room in which the sun shines during the daytime is much brighter than at nighttime. However, even in the daytime, if it is rainy or cloudy, the amount of light is much less than when the sun is shining, and it feels dark. Even at night, it can be said that it is bright under illumination, for example, when a vehicle is illuminated by the headlights of an oncoming vehicle or in a tunnel. Therefore, the first display mode may be selected even during the daytime, and the second display mode may be selected even during the nighttime.
Here, the "reflector" may be any object that can reflect image light projected from the display screen so that the user can see it, and may be a mirror object or a transparent object. The transparent body is a half mirror, that is, a combiner because the user cannot see it unless the image light projected from the display screen is reflected even if it is a transparent body. The reflected virtual image may be a two-dimensional image or a three-dimensional hologram.
In the case of "reflecting on a reflector", the display screen may be reflected directly on the reflector, or the light may be reflected by an optical system, such as a mirror or passed through a lens, before reaching the reflector. may

Further, as means 2, it is preferable to make it possible to select either the first display mode or the second display mode.
This makes it possible for the user to select either the first or second display mode, which is easier for the user to view, and to view the information. For example, when the user feels that the surroundings are dark even in the daytime, the user can select the first display mode, thinking that it is easier to see the display contents indirectly. Conversely, it is possible to select the second display mode by thinking that it is easier to see the display contents directly even at night under sufficient illumination.
The selection may be made subjectively by the user himself/herself, but it is preferable to have selection means or change means for appropriately changing between the first display mode and the second display mode for selection. It is preferable that the user has selection means for selecting one of the first display mode and the second display mode when the user himself/herself makes a selection. As the selection means, an operation means such as a changeover switch or a remote controller is preferable. As the selection means or change means, it is preferable to automatically perform, for example, control means, as will be described later.
Further, as means 3, it is preferable that the user's line-of-sight direction with respect to the reflector in the first display mode and the user's line-of-sight direction with respect to the display screen in the second display mode are the same.
This allows the user to continue looking at the display screen without moving the line of sight in either the first display mode or the second display mode. Here, "same line-of-sight direction" may be defined as a direction of only one point, but may also be configured as a concept having a width within the field of view including the line-of-sight direction.

Further, as means 4, control is performed by the control means so that a reversed image is displayed on the display screen in the first display mode, and a normal image that is not reversed is displayed on the display screen in the second display mode. It's good.
As described above, in the first display mode in which the image light is reflected by the reflector and is indirectly viewed by the user, the image light is reflected by the reflector and is mirror image-inverted for viewing. On the contrary, by displaying an image reversed to the reverse side, it is possible to allow the user to view an image displayed in a non-symmetrical manner, such as numbers and characters, as a correct image that can be originally read by the user.
On the other hand, since the user directly views the display screen in the second display mode, the correct image is displayed on the display screen.

Further, as means 5, the control means preferably displays a reverse image on the display screen so that the upper side of the visual field of the user viewing the reflector in the first display mode is the upper side of the display information.
The upper side of the user's field of view of the image reflected by the reflector is the upper side of the display information, so that the user can easily read images such as numbers and characters that have a vertical direction. Similarly, when viewing the display screen directly in the second display mode, the upper side of the user's visual field should be the upper side of the display information.

Further, as means 6, it is preferable to make the design of the display content viewed by the user in the first display mode different from the design of the display content viewed by the user in the second display mode.
As a result, the image can be designed according to the respective viewing conditions when the display screen is indirectly viewed by the user and when the display screen is viewed directly by the user. For example, according to the distance to the user, the farther image may have relatively large characters. In addition, in the case where the display screen is reflected by a reflector so that the user can indirectly see the display content, for example, the image may be reflected on the front and back sides of the reflector due to the thickness of the reflector, resulting in a double image. In that case, it is better not to use a design that is too detailed, and it is also possible to use rough, large letters or symbols, for example. On the other hand, when the user directly looks at the display screen, there is no particular need to do so. Therefore, when displaying the same characters or numbers, the second display mode is relatively preferred over the first display mode. It may be displayed in a smaller size.
In addition, the "design" is considered to be the same design for the correct image and the reversed image in the case of images displayed in a non-symmetrical manner, such as numbers and characters.

Further, as means 7, in the case of the first display mode, the user is notified that the second display mode is easier to see, and in the case of the second display mode, the user is notified of the It is preferable to provide notification means for notifying that the first display mode is easier to see.
As a result, for example, when the user is currently indirectly viewing the display content (in the case of the first display mode), the user is informed that the second display mode is easier to see due to the change in ambient brightness. It becomes possible to select the first display mode which is easy to see by oneself. In that case, it is preferable to change the display mode by operating operating means such as a changeover switch or a remote control (remote controller).
As such notification means, for example, auditory means such as voice from a speaker for the user, or visual means on a display screen may be used.

Further, as means 8, the display screen is preferably movable between a first position where the user can indirectly view the display contents and a second position where the user can directly view the display contents. .
This provides the user with indirect viewing (i.e., the first display mode) and direct viewing (i.e., the second viewing mode) of the display screen by simply moving the display screen between the first position and the second position. ) is selectively possible.
Further, as means 9, the control means preferably controls a moving mechanism for moving the display screen to place the display screen at the first position or the second position.
As a result, the control means controls the moving mechanism to automatically arrange the display screen at the first position or the second position even if the user does not manually move the display screen. Of course, the configuration may be such that the user moves the display screen by hand.

Further, as means 10, the control means controls the driving operation of the movement mechanism based on the detection value of the light detection means to move the display screen to either the first position or the second position. It is better to
The control means determines the detection value of the light detection means, that is, the threshold value of brightness, and drives the moving mechanism according to whether it is brighter or darker than that value to place the display screen at the first position or the second position. I tried to let As a result, the user can view the information in either the first display mode or the second display mode, whichever is easier for the user to see depending on the brightness. For example, when it is desirable to use the first display mode in which the user can indirectly see the display contents by reflecting the display screen on a reflector in the dark at night, the control means sets the display screen at the second position. If so, it can be moved to the first position (in this case, if the display screen is in the second position, it is not moved).
Further, as means 11, the control means controls the driving operation of the movement mechanism based on the position information from the position detection means to move the display screen to either the first position or the second position. It is better to let
The control means can acquire the detected position information (for example, latitude data and longitude data) based on the position information from the position detection means. From the position information and the current time, it is possible to determine what kind of light intensity condition the position is currently in, for example, whether it is bright daytime or nighttime. You can move the display screen to The means for measuring the current time may be in the position detection means or in the control means. GPS (Global Positioning System), for example, is preferable as the position detecting means.

Further, in the case where both the light detection means and the position detection means are provided as the means 12, the control means controls the driving operation of the moving mechanism based on the position information from the position detection means at night. It is preferable to move the display screen to either the first position or the second position.
For example, since it is originally dark at night, the control means should control the drive operation of the moving mechanism by judging that it is "dark" based on the detection value of the light detection means. For example, when the system is installed in a vehicle, there is a possibility that it may be judged to be "bright" even if it is temporarily exposed to the intense headlights of an opposing vehicle. Changing the display mode with such temporary brightness may confuse the user. Therefore, in the case where both the light detection means and the position detection means are provided, the control means preferentially controls the detection value from the position detection means, thereby providing a display suitable for nighttime without confusing the user. Aspects become possible.

Further, as means 13, the display screen is placed at the first position by laying down at an upper position of the housing, and is placed at the second position by standing up from the first position. It is better to
By standing up the display screen in this way, the user can easily see the display screen directly, and by laying down, the user will not be hindered from seeing the reflector.
Further, as means 14, the reflector is arranged so as to face the user at a position farther from the position of the display screen in the upright state than the position of the display screen in the upright state, and the display screen is directed toward the reflector from the upright state. It is better to make it fall down.
With this configuration, when the user is standing up, the display screen facing the user is temporarily hidden by falling down, and instead, a virtual image of the image light on the display screen is reflected by the reflector and appears in a characteristic effect. As a result, the user finds it interesting, and since the display mode is switched quickly, the user does not feel much stress in switching the display mode.

Further, as means 15, the housing may be held at an arbitrary elevation/depression angle with respect to the mounting surface by holding means.
If the elevation angle of the housing can be arbitrarily changed in this way, even if the first position and the second position of the display screen are fixed and cannot be changed, the angle of the housing itself can be changed. It is possible to change the orientation of the first position and the second position of the display screen with respect to the user, and it is possible to set according to the user's line-of-sight direction.
Further, as the means 16, the housing is preferably held at an arbitrary rotational position by holding means.
Since the display screen can be directed to the user regardless of where the housing is arranged around the user, the latitude in selecting the position where the housing is installed is improved.
Further, as means 17, it is preferable that the mounting angle of the reflector with respect to the housing can be changed.
As a result, when the display screen is reflected by the reflector in the first display mode and the display content is indirectly viewed by the user, the attachment angle of the reflector can be set to a suitable angle according to the user's line of sight. .

Moreover, as means 18, the reflector is preferably detachable from the housing.
For example, it is advantageous when the reflector is an obstacle or when it is damaged and needs to be replaced. Furthermore, if the user selects only the second display mode, that is, the usage method of directly viewing the display screen, the reflector is unnecessary and can be removed.
Moreover, as means 19, the reflector is preferably transparent.
With such a reflector, the surroundings of the display contents reflected by the reflector become transparent, so that the display contents are displayed as if they are floating in the air, which has a great design effect. In particular, in an arrangement such as the above means 14, in which the display screen and the reflector are arranged so as to overlap front and back as seen from the user, if the reflector is transparent, the background of the display screen does not become too dark. does not feel dazzling when looking at the display screen.

Further, as means 20, it is preferable that the end face of the reflector is roughened so that the end face is diffusely reflected by the light emitting means arranged facing the end face.
As a result, the light incident on the reflector from the light-emitting means is diffusely reflected at the end face position of the reflector, so that it can be made conspicuous, and the design effect is also enhanced, so that the user's interest in using the reflector increases. . At this time, the position where the light emitting means is arranged should not be subjected to surface roughening treatment in order to allow light to enter the interior of the reflector efficiently. Moreover, it is preferable to cause the light emitting means to emit light based on the occurrence of some event by the control means. For example, an event is input in advance when the radar detection device detects an alarm target such as a GPS alarm, radar wave alarm, or radio alarm while the vehicle is running, or when it is determined that the time is exactly 0 minutes. This is the case where it is meaningful to notify the user of the user's birthday, etc., and it is preferable to notify the user.
Further, as means 21, the reflector preferably has a concave surface portion for enlarging and displaying the reflected display content.
As a result, the reflector can magnify the reflected display content, and the user can view the enlarged screen information more than when the user directly views the display screen without increasing the area of the reflecting surface of the reflector. becomes possible.
In addition, as means 22, both a first reflector having a concave portion for magnifying and displaying display contents and a second reflector having a flat portion not to be magnified are provided as the reflector, and either one of them is selectively provided. It should be available for
Thereby, in the first display mode, the user can select a pattern in which the display contents are enlarged and displayed, and a normal pattern in which the contents are not enlarged.

Further, as means 23, it is preferable to make the luminous intensity of the display screen in the first display mode higher than the luminous intensity of the display screen in the second display mode.
As described above, if the brightness of the display screen is the same, the brightness is relatively attenuated when viewed indirectly rather than when viewed directly. Therefore, even if the brightness is just right when viewed directly, it may feel dark when viewed indirectly. Therefore, by configuring in this way, it is possible to compensate for the lack of light amount when the display content is indirectly viewed by the user by reflecting the display screen on the reflector in the first display mode.

Further, as means 24, the housing is mounted on a vehicle, and the control means controls the display screen to be displayed at the second position when the driving source of the vehicle is stopped. The normal image is displayed on the display screen by moving it to the first position, and when the display screen is at the second position, the display screen is reversed on the display screen as it is without being moved. It is preferable to control so as to display a normal image that is not displayed.
When an information display system is mounted on a dashboard of a vehicle, for example, and the driving source of the vehicle is stopped, the image on the display screen at the second position can be directly viewed from the outside by configuring as described above. can be made If the installation location is on the dashboard, it is good for an outsider to see the image on the display screen through the window if the display is laid down against the dashboard. The non-inverted normal image is preferably an image with content unrelated to vehicle driving. For example, it may be message information for a third party looking into the stopped vehicle, which is not information related to driving, such as a slogan warning a third party, a decorative animation, or a company advertisement. In other words, it is preferable to use the display screen 14 like a sort of mobile phone or personal computer screen as a standby screen.

Further, as the means 25, the control means preferably notifies the vehicle running information by voice when the first display mode and the second display mode are not used.
As a result, the user can know information about the running of the vehicle without directly or indirectly looking at the display screen. It includes not only external information such as road traffic information, but also internal information such as vehicle speed information and fuel consumption information.
Further, as the means 26, the display contents to be displayed on the display screen preferably include external information during vehicle travel.
The external information on the display screen includes, for example, road traffic information. Internal information such as vehicle speed information and fuel efficiency information, and information such as terrestrial digital TV and DVD as audio equipment may be switched or displayed simultaneously on the display screen.

According to the present invention, indirect viewing and direct viewing of the display screen according to the user's situation are one.
Only one display screen is required.

Controller MC drives motor assembly 18 to place display 13 in a reclined first position or an upright second position based on values detected by GPS receiver 22 and/or optical sensor 23 . If the value detected by the GPS receiver 22 or the optical sensor 23 determines that the display 13 is currently at the first position, the controller MC moves toward the second position. to drive the motor device 18. On the other hand, if it is determined that the current position is appropriate, the motor device 18 is not driven. Similarly, when the indicator 13 is currently at the second position and it is determined that it is not appropriate, the motor device 18 is driven so as to move toward the first position. On the other hand, if it is determined that the second position is appropriate, the motor device 18 is not driven. When the motor device 18 is driven, the controller MC acquires the phase during rotation by the rotary encoder 19, and stops driving the motor device 18 at the first position and the second position based on the obtained value.

Further, when the display 13 is in the first position where the display 13 is laid down on the display screen 14, the controller MC reverses the correctly readable characters as shown in FIG. is displayed with the display content so that the upper side of is on the rotation base side. The layout of the display screen 14 and the information displayed on the screen can be arbitrarily selected by the user from the database 44 and set using the remote controller. In FIG. 4, as an example of an indirect vision layout, a speed number 51 for digitally displaying speed is displayed large in the center, and icons 52 corresponding to GPS alarm, radar wave alarm, and radio alarm are displayed diagonally above the number. . The icon 52 is displayed on the display screen 14 for a certain period of time when an alarm target such as GPS alarm, radar wave alarm, or radio alarm is detected. Below the speed number 51, a speed meter 53 is displayed as an analog display of the speed.
On the other hand, when the display 13 is in the second standing position, the display screen 14 is placed in the standing mode and displayed in the correct orientation as shown in FIG. At this time, unlike in the lying down mode, the lower side of the displayed content, which is the lower side when the player stands up, is displayed so as to be on the rotation base side. In FIG. 3, as an example of a direct view layout, a speed meter 55 that displays the speed in analog form and a speed number 56 that displays the speed in digital form are displayed so as to overlap each other, and an ecometer 57 and a clock 58 are arranged on the side. ing. In addition, below the main display, an icon 59 indicating the H system as a display when a notification target such as GPS alarm, radar wave warning, or radio alarm is detected, and the speed limit at the current position Distance to the notification target ( An icon 60 indicating 50 Km/H in this case), a display of a notification target (here, "H system"), a display 61 indicating the distance and direction to the notification target, and a digital time display 62 are arranged. ing. The icon 52 and the icon 59 are information of the same meaning, but are displayed larger in FIG. 4 which is indirect vision. In Embodiment 1, the controller MC determines whether the display 13 is at the first position or the second position based on the numerical value of the rotary encoder 19 . Further, the switching timing of the two types of display screens 14 is also performed based on the numerical value corresponding to the first position or the second position of the rotary encoder 19 .

Further, when the controller MC judges that the vehicle is stopped based on the vehicle information acquired from the vehicle diagnostic connector, the display screen 14 at the first position displays a correct image that is not mirror-inverted, for example, as shown in FIG. Orientation display. However, unlike FIG. 3, the direction of display at this time is such that the upper side of the display content is on the rotation base side. That is, the display screen 14 in the lying state as shown in FIG. 9 is displayed upside down from FIG. 3 so that it can be easily read when viewed from the outside on the front window FW side. The display here is message information to a third party looking into the stopped vehicle, not information about driving, such as a slogan warning a third party, a decorative animation, or a company advertisement. In the first embodiment, the controller MC scrolls and displays such message information on the display screen 14 . For example, the display screen 14 is used as a kind of standby screen by repeatedly scrolling the text display of "Aiming at the vehicle is a crime" and "An alarm is installed. Please do not touch the vehicle." The user can arbitrarily select standby screen data relating to the types and layouts of such slogans from within the database 44 and set them using the remote controller. In addition, the company name is a slogan created by the user by using the remote control to type in the character information "○○" of the slogan, such as "Please take care of ○○ Co., Ltd.". It is stored in a card, arbitrarily called by a remote controller, enlarged, decorated, etc., and displayed as a character display on a display screen 14.例文帳に追加
3, 4 and 8, the background is represented in white for the convenience of drawing, but in the actual display screen 14, the background is black (that is, relative to the characters, etc.) so that the display contents can be easily seen. dark background).

Also, the controller MC executes the GPS warning function at predetermined timing (for example, at intervals of 1 second). The controller MC obtains the distance between the latitude and longitude data of the target stored in the database 44 and the latitude and longitude data of the current position detected by the GPS receiver 22. ), it is displayed on the display screen 14, and at the same time, an approach warning voice such as "1 km ahead, expressway service area" is output from the speaker device 24. - 特許庁At the same time, the LED 28 is synchronized with the timing of the sound output from the speaker device 24 and flashes to give a lighting warning.
Further, the controller MC executes a radar wave warning function based on detection of a signal corresponding to microwaves in a predetermined frequency band emitted from the radar from the microwave detector 41 . When the controller MC determines that the microwave detector 41 has detected a predetermined microwave, it displays an alarm screen corresponding to the type of microwave on the display unit 14, and also has an alarm function of outputting an alarm sound from the speaker device 24. is. For example, when microwaves in the frequency band of microwaves emitted by radar are detected by the microwave detector 41, for example, radar icons, schematic diagrams, or photographs stored in the database 44 are displayed on the display unit 14, The voice data stored in the database 44 is read out, and the loudspeaker device 17 is made to give a voice notification such as "50 m ahead H system". At the same time, the LED 28 is synchronized with the timing of the sound output from the speaker device 24 and flashes to give a lighting warning.
The controller MC executes a radio alarm function of issuing an alarm by the radio receiver 15 so as not to hinder the traveling of the emergency vehicle when it receives the radio wave emitted by the emergency vehicle. In the radio alarm function, control radio, car location radio, digital radio, special radio, station active radio, police phone, police activity radio, tow radio, helicopter radio, fire helicopter radio, firefighting radio, emergency radio, expressway radio , security radio frequencies, etc., and when a radio signal is received at the scanned frequency, an icon or a schematic diagram indicating that the radio signal corresponding to the frequency stored in the database 44 for each radio type has been received is displayed. The alarm screen is displayed on the display unit 14 , and the voice data stored in the database 44 for each wireless type is read out, and an alarm sound indicating the wireless type is output from the speaker device 24 . For example, when a police radio is received, for example, a voice such as "This is a police radio. Watch out for speed" is output. At the same time, the LED 28 is synchronized with the timing of the sound output from the speaker device 24 and flashes to give a lighting warning.

The operation of the radar detection device 10 having such a configuration will be described together with the control of the controller MC.
First, as shown in FIG. 5, when using the radar detection device 10, the user installs the radar detection device 10 in a position where it does not interfere with viewing the front through the front window FW on the dashboard D in the vehicle, and connects it to a vehicle diagnostic connector (not shown). and turn on the main switch. For installation, the main body case 11 is arranged so that the optical sensor 23 arranged on the inclined wall portion 12 faces the front, that is, faces the front window FW. Then, the main body for the user is arranged in advance so that the user (driver) can see the display screen 14 directly and the display screen 14 can see the virtual image reflected on the front window FW. The direction of the case 11, the angle with respect to the dashboard D, etc. are determined by appropriately moving the main body case 11 with respect to the stand 30. - 特許庁
When the user is ready to drive the vehicle (for example, the engine is on if the vehicle is an internal combustion engine vehicle) or the accessory power supply (ACC) is turned on, the power is automatically turned on to the radar detector 10 via the vehicle diagnostic connector. . The indicator 13 of the radar detection device 10 is initially in the retracted state, i.e., the first position (down state) in FIG. Hereinafter, the processing of the controller MC after the power is turned on will be described based on the flow chart of FIG. It should be noted that if the following processing is performed frequently, the display 13 may be raised and laid down many times at short timings, which may cause annoyance. It is preferable to execute it in units of minutes or hours in long intervals considering changes in weather. For example, the following will run every 10 minutes:
First, in step S1, the controller MC determines whether it is night or day based on the position information and time information received by the GPS receiver 22. FIG. Then, when it is determined that it is night in step S1, the controller MC determines whether the display 13 is currently at the first position in step S2. This is determined based on the detected value of the rotary encoder 19 described above. When it is determined in step S2 that the controller MC is in the first position, in step S3 the controller MC causes the display screen 14 to display the display contents in the normal readable form, which is a mirror image reversal, and the upper side of the entire display contents is displayed on the display screen. 14 (that is, the lower side when viewed directly) is controlled to be displayed on the display screen 14, and the process is temporarily terminated. In such a case, as shown in FIGS. 5 and 6, the display screen 14 is reflected by the front window FW, and the virtual image is displayed as if it were floating in the air outside the front window FW for the user to see. Become. The character information in this virtual image state is in the correct orientation that humans can normally read (recognize), and the upper side of the displayed image is the upper side of the user's visual field, which is also the correct vertical direction that humans can normally recognize. At this time, since it is nighttime, the surroundings are dark, and the display screen 14, which is often felt dazzling when viewed directly at night, is not too dazzling, and the amount of light is attenuated by being reflected by the front window FW, so that the user can achieve just the right amount of light. The display screen 14 can be seen with a good amount of light.
On the other hand, if it is determined in step S2 that the display 13 is not in the first position (that is, in the second position), the motor device 18 is driven to move the display 13 to the first position in step S4. to move the display 13 to the first position. Then, the controller MC causes the process of step S3 to be executed.

On the other hand, if the controller MC determines in step S1 that it is not nighttime, it determines whether it is daytime and whether the light sensor 23 detects the brightness above the predetermined threshold in step S5 for the first time. Determine if it is bright enough. In this way, the determination by the GPS receiver 22 is performed first, and then the determination by the optical sensor 23 is performed. This is to prevent malfunction in such a case because the optical sensor 23 may calculate a value that is higher than the threshold value due to light such as light. If it is determined in step S5 that the brightness is above the predetermined threshold value, in step S6 the controller MC determines whether the display 13 is currently at the first position in the same manner as described above. In this case, it is preferable that the display 13 is at the second position. Therefore, when it is determined that the display 13 is at the first position, the controller MC drives the motor device 18 in step S7 to move the display screen 14 to the second position (upright position). state), and in step S8, the display content is a correct image that is not reversed, and the lower side of the entire display content is on the base side of the display screen 14 (that is, the image is normally recognized by a normal person as described above). Correct up/down direction possible) Control is made to display on the display screen 14, and the process is temporarily terminated. In such a case, the user can directly see the display screen 14 on the front side of the main body case 11 (that is, near the user) as shown in FIG. At this time, since it is daytime when there is sufficient light, the user's pupils are dilated, so that the user can see the display screen 14 with just the right amount of light without feeling dazzled even when looking at the display screen 14 directly.
On the other hand, if it is determined in step S6 that it is not in the first position, it is determined that the display 13 is already in the second position (upright state), the process proceeds to step S8, and the controller MC executes the process of step S8. let it run.

On the other hand, if it is determined in step S5 that the brightness is lower than the predetermined threshold value, it means that the surroundings are not bright, and that it is not nighttime, but it is rainy weather, cloudy weather, evening, etc., where the amount of light is small. to decide. Then, in step S9, the controller MC determines whether the display 13 is currently at the first position in the same manner as described above. In this case, it is preferable that the display 13 is located at the first position. Therefore, when it is determined that the display 13 is at the first position, in step S10, the controller MC displays the reverse image of the display contents in the normal readable form on the display screen 14, and displays the reverse image. The display screen 14 is controlled so that it is oriented such that the upper side of the entire display content is on the base side of the display screen 14 (that is, the lower side when viewed directly), and the process is temporarily terminated. On the other hand, if it is determined in step S9 that the display 13 is not in the first position, it is determined that the display 13 is in the second position (upright state), and the controller MC drives the motor device 18 to display the display screen 14 in step S11. 1 (upright state), and then the controller MC executes the process of step S10, and the process is temporarily terminated.

In such a configuration, when the radar detection device 10 detects an alarm target such as a GPS alarm, a radar wave alarm, or a radio alarm while the vehicle is running, even if the vehicle is in the first position (laying down state), the second position is detected. Even in the position (upright state), it is displayed on the display screen 14 at each position, for example, as shown in FIGS. 3 and 4, and the user can indirectly or directly view the display contents in an appropriate viewing environment. . At the same time, a sound is announced from the speaker device 24 through the sound hole 25, and the pattern 27a of the panel 27 with the mark blinks and shines as the LED 28 blinks to alert the user.
When the vehicle stops and the controller MC detects engine stop information of the vehicle from the vehicle diagnosis connector, if the indicator 13 of the radar detection device 10 is in the first position (down state), If it is in the second position (upright state), the motor device 18 is driven so as to move to the first position (down state), and the control for informing the user of the driving information is terminated.
When the controller MC detects that the engine of the vehicle has stopped, after a predetermined period of time, the display content displayed on the display screen 14 is turned upside down from that shown in FIG. Display as a standby image.

The user can arbitrarily change the setting conditions from the infrared light receiving section 26 by operating a remote controller (not shown). For example, the layout of the display screen 14 and the types of information displayed on the screen can be replaced and changed (layouts other than those shown in FIGS. 3 and 4, and information related to driving displayed in FIGS. ), change the brightness of the display screen 14, stop the sound output from the speaker device 24, always use the display 13 only in the first position (down state), or conversely always in the first position. It should only be used in position 2 (standing). Alternatively, the display function of the display screen 14 is not used at all (that is, the display 13 is held at the first position), and the information is notified only by the sound output from the speaker device 24 or (and) the lighting of the pattern 27a of the panel 27 with the mark. use it to let
Also, the user can set whether or not to display the standby image by operating the remote controller. In the case of displaying, setting conditions such as the timing of display, the type of standby image, and the display method whether to scroll or not can be arbitrarily changed.

With the configuration as described above, the radar detection device 10 of the first embodiment has the following effects.
(1) Since the display screen 14 is automatically switched between direct viewing and indirect viewing depending on the brightness, it is easier for the user to view the display screen 14 under conditions such as nighttime, dark daytime, and bright daytime. Information is available at.
(2) Since the same display screen 14 of the display device 13 is used for direct vision and indirect vision, the radar detection device 10 can be made compact and lightweight, and can be easily handled when the user installs the device in a narrow vehicle. This is advantageous because it is easy to install and the tolerance of the installation location increases.
(3) In indirect vision, the virtual image on the display screen 14 is displayed at a farther position than in direct vision, and the brightness is relatively attenuated. Furthermore, the thickness of the front window FW may cause double projection of the virtual image. However, the display content of the display screen 14 in indirect vision is different from that in direct vision, and simpler and larger patterns are used to make it easier to see.
(4) When the vehicle is stopped, the display 13 is placed in the first lowered position, so that the upright display 13 is less likely to interfere with the user getting in and out of the vehicle, cleaning the inside of the vehicle, or the like. .
(5) Since the GPS alarm, radar wave alarm, and radio alarm are issued from the display screen 14 whether viewed directly or indirectly, the basic functions of the radar detection device 10 are maintained for the user. In particular, since it is difficult for the user to understand what is being reported in indirect vision, visibility is improved by displaying the indirect vision in a larger size.
(6) By user's operation, for example, audio output from the speaker device 24 is stopped, or conversely, without using the display function of the display screen 14, audio output or (and) lighting of the pattern 27a of the panel 27 with the mark is performed. Since information can be notified, users can acquire information in various modes.
(7) Since the GPS receiver 22 and the optical sensor 23 are arranged on the side where data can be easily obtained, it is possible for the user to obtain more accurate information.
(8) When the vehicle is stopped and in the parking state, the standby image is displayed on the display screen 14 of the display 13 in the first position (down state). It is possible to send various messages to three parties.
(9) The display unit 13 is composed only of the substrate of the LCD module and does not have an extra frame wrapped around the outer periphery, so that the weight can be reduced and the load when the motor device 18 is driven is reduced. Since the display screen 14 is supported via the both ear-like support portions 16 and at the same time supported by the flexible cord 15, the display screen 14 does not shake greatly due to the vibration of the vehicle even if the weight is reduced, making the screen easy to see for the user. there is
(10) Since the display screen 14 uses a dot matrix display such as an LCD that emits light by backlight, it can be used in situations where the surroundings become dark such as when a headlight is required for indirect vision, such as at night. Since it is sufficient to limit the brightness, not so high brightness is required, and on the other hand, the display screen 14 can be directly viewed by the user in a bright environment such as daytime. In addition, a dot matrix display such as an inexpensive general-purpose liquid crystal can be used, which contributes to cost reduction. In addition, high resolution and clear display can be maintained even when viewed directly.

(Embodiment 2)
Embodiment 2 is obtained by disposing a reflecting plate 71 as a reflector in Embodiment 1. FIG. In the illustration of the second embodiment, the same reference numerals are assigned to the same configurations as in the first embodiment, and detailed description thereof is omitted. As shown in FIGS. 11 to 13, a reflecting plate 71 is arranged on the top plate 11b side of the body case 11 of the radar detection device 70 of the second embodiment. Reflector plate 71 is a transparent integral molded member made of polycarbonate. The reflecting plate 71 is composed of a rectangular parallelepiped main body 72 whose inner surface is slightly curved concavely in the vertical and horizontal directions, and a pair of left and right legs 73 formed at the base of the main body 72 . The entire circumference of the end surface of the reflection plate 71 is roughened like a frosted glass (however, only a portion is left transparent as will be described later). The main body 72 is configured to be wider than the display 13 in the lateral width direction and to have the same length in the vertical direction (larger than the display 13 as a whole). An antireflection coating is applied to the outer surface of the reflection plate 71 .
As shown in FIG. 14, discs 74 are formed inside the legs 73 respectively. A rotating shaft 75 is formed in the center of the disk 74, and four engaging protrusions 76a to 76d are formed on the outer circumference of the disk 74. As shown in FIG. As shown in FIG. 15, the reflecting plate 71 rotates the rotation shaft 75 of the leg portion 73 with respect to the shaft hole 77 formed in the rear portion of both side walls 11d of the main body case 11 (the position adjacent to the inclined wall portion 11a). It is possible to swing with respect to the main body case 11 by axially supporting the main body case 11 . The reflecting plate 71 can be removed by bending both legs 73 outward and removing the rotating shaft 75 from the shaft hole 77 .

A protrusion 78 having a circular cross section is formed at a position adjacent to the shaft hole 77 of the body case 11 . As shown in FIGS. 14 and 15, when the reflecting plate 71 is attached to the main body case 11, the protrusions 78 are arranged at positions where they can interfere with the engaging protrusions 76a to 76d. Therefore, the reflection plate 71 cannot be rotated unless a predetermined torque or more is applied to the reflection plate 71 because the projections 78 interfere with the engaging projections 76a to 76d. On the other hand, if a torque greater than a predetermined value is applied, the disk 74 and the protrusions 78 are bent and the engaging protrusions 76a to 76d get over the protrusions 78, so that the reflection plate 71 can be rotated. In the second embodiment, when the reflecting plate 71 in FIG. 14A stands upright, the projection 78 is fitted between the engaging projections 76a and 76b, making it difficult to rotate in either direction. As a result, the reflecting plate 71 is held. On the other hand, in the position where the reflecting plate 71 is laid down in FIG. 14B, the projection 78 is fitted between the engaging projections 76c and 76d, and the reflecting plate 71 is similarly held. In the second embodiment, the projections 78 are fitted at three positions between the adjacent engaging projections 76a to 76d so that the reflection plate 71 can be held in position.
As shown in FIGS. 12 and 13, when the reflecting plate 71 is held upright, the trajectory of the indicator 13 when reciprocating between the first position (falling position) and the second position (upright position) is shown. Since the reflection plate 71 is not inside, the movement of the display device 13 is not hindered. When the display 13 is in the first position (down position), a cover is placed on the display 13 from above as shown in FIG. can be
As shown in FIGS. 11 to 13, an LED 80 is provided on the rear slanted wall portion 11a of the body case 11. As shown in FIGS. The LED 80 is arranged at a position adjacent to the reflecting plate 71, and is arranged so that the irradiation direction faces the end surface of the reflecting plate 71 and is oriented inward when the reflecting plate 71 is upright. Only the end faces facing the LEDs 80 are left transparent without being roughened, so that light can easily enter.

FIG. 17 is a block diagram for explaining the electrical configuration of the control section 21 of the radar detection device 70 according to Embodiment 2. As shown in FIG. An LED 80 is connected to the controller MC in addition to the electrical configuration of the first embodiment. When an event occurs, the controller MC lights the LED 80 according to the event to cause a predetermined blinking display to attract the user's attention. As an event, in the second embodiment, when the radar detection device 70 detects an alarm target such as a GPS alarm, a radar wave alarm, or a radio alarm while the vehicle is running (that is, the display screen 14 simultaneously displays that effect). ), and when each time exactly 0 minutes is acquired, the user's birthday (executed when the first radar detection device 70 is activated on the day of the birthday) is prepared by the user's remote control input. The user can arbitrarily change the setting conditions such as whether or not the LED 80 emits light from the infrared light receiving section 26 by operating a remote controller (not shown), and in what event the light is emitted.

The operation of the radar detection device 70 having such a configuration will be described.
When using, the user installs the radar detection device 70 on the dashboard D in the vehicle by the same operation as in the first embodiment. Then, the reflecting plate 71 of FIG. 11 as a protective cover is manually operated from the position superimposed on the display 13 at the first position to obtain the upright state of FIG. The method of use thereafter is the same as that of the radar detection device 10 of the first embodiment.
By adopting such a configuration, the radar detection device 70 of the second embodiment, like the radar detection device 10 of the first embodiment, allows the user to indirectly or directly understand the display contents displayed on the display screen 14 appropriately. can be viewed in a normal viewing environment. In the second embodiment, in indirect vision, the display screen 14 is reflected by the inner surface of the reflecting plate 71 as shown in FIG. It will be visible. Further, in the second embodiment, as in the first embodiment, the sound is notified from the speaker device 24 through the sound hole 25, and the pattern 27a of the marked panel 27 blinks and shines by blinking the LED 28 to alert the user. is done.
Moreover, when an event occurs, the LED 80 emits light while blinking to irradiate the reflecting plate 71 .
When the vehicle stops, the indicator 13 is positioned at the first position (down state) as in the first embodiment. Since the reflecting plate 71 is in an upright state even when the vehicle stops, the user manually rotates the reflecting plate 71 in the laying direction with respect to the main body case 11 as desired to bring it into the state shown in FIG.

With the above configuration, the radar detection device 70 of the second embodiment has the following effects in addition to the effects of the first embodiment.
(1) For indirect vision, since the reflective plate 71 is provided separately from the front window FW, the user can see indirectly at a closer position, so the display screen 14 does not have to be so bright.
(2) Since the reflection plate 71 is coated with an antireflection coating, it is difficult for the image to be duplicated, and a clear virtual image can be obtained.
(3) The reflective plate 71 is arranged to overlap the display 13 when retracted, and serves as a protective cover when the user is set not to look at the display screen 14 .
(4) The reflective plate 71 can be removed as needed, and even if it is removed, the vehicle information is still notified, so it can be used according to the user's policy.
(5) Since the reflection plate 71 enables indirect vision, the radar detection device 70 does not necessarily have to be placed in front of the front window FW, and the user has more flexibility in the placement position.
(6) Since the reflective surface of the reflective plate 71 is formed in a concave shape, the displayed contents are magnified, making it easier for the user to see.
(7) In the radar detection device 10, the stand 30 is composed of a bracket portion 31 and a base 32 for positioning the position-changing display 13 and the reflecting plate 71. It can be displaced to any position within a wide range of motion. Therefore, the display device 13 and the reflection plate 71 cannot be rotated and can only be moved between two fixed positions, but both the display device 13 and the reflection plate 71 can be arranged at positions that are sufficiently easy for the user to see.
(8) When an event occurs, the LED 80 emits light while blinking to illuminate the reflection plate 71 . Therefore, the end portion of the reflection plate 71 diffusely reflects the light to produce an illumination effect that surrounds the reflection plate 71, thereby arousing the playfulness of the user.

The present invention may be embodied and implemented in the following modes.
In the first embodiment described above, while the engine is stopped and the vehicle is parked, a third party can view the fallen display screen 14 of the radar detection device 10 installed on the dashboard D from outside the front window FW. It was designed to be visible from the bonnet side. For example, in Embodiment 2, as shown in FIG. 18, a virtual image reflected by an upright reflecting plate 71 may be viewed. In this case, since a third person sees from the rear side of the reflective plate 71 on the driver's (user's) side, the mirror image displayed on the display screen 14 is reversed in the same manner as in the first embodiment. The display screen 14 in the laid down state as in FIG. 8 is displayed upside down from FIG. 3 so that it can be easily read when viewed from the outside on the front window FW side. Of course, even in the second embodiment, it is possible to adopt a configuration in which the reflection plate 71 is removed and the display screen 14 is directly viewed by a third party as in the first embodiment. The user may choose to display either pattern.
- In the second embodiment, the reflecting plate 71 having a concave reflecting surface with a magnifying lens effect is prepared. A plate may be prepared for replacement so that it can be exchanged with the reflective plate 71 prepared by default. By configuring in this way, the user can select his or her preference or whichever plate is easier to see.
- In each of the above embodiments, a remote controller (not shown) is used by the user to perform various inputs and change operation of setting modes. good too.
The rotation position of the indicator 13 is detected using the rotary encoder 19 in each of the above-described embodiments, but other detecting means such as a limit switch or a proximity switch may be used.
・In each of the above embodiments, the brushless D is used as the motor device 18 for rotating the display device 13 .
Although C motors have been used, other types of motors such as servo motors, linear motors, etc. may be used.
・In each of the above embodiments, the display unit 13 is automatically lowered and raised by controlling the motor device 18. However, the user manually operates the display device 13 without using a driving means such as the motor device 18. You can go by For example, when the display 13 is laid down in the default state, it is better to stand up as a result of detection by means capable of detecting brightness such as the optical sensor 23 (that is, to directly view the display screen 14). When the controller MC determines that the brightness continues, the user is notified of the fact, and the user's operation (manual operation or, for example, a remote control or an input switch may be used) to change the lying state to the standing state. (or vice versa). The user may manually lay down and raise the display 13 without using a driving means such as a motor. In addition, the notification may include visual notification such as text display indicating that the screen is easier to see when switched to the display screen, auditory notification using sound from a speaker device or alerting sound such as a chime, or both of them. Also, even if there is no means for detecting brightness, the user may subjectively switch between the lying state and the standing state by the user's operation. Even in such a case, the rotation position of the display 13 can be detected using the rotary encoder 19 as described above or other detection means.

- Although both the GPS receiver 22 and the optical sensor 23 are used to lay down and stand up the display device 13 in each of the above-described embodiments, only one of them may be used.
The amount of light of the backlight of the liquid crystal display, which serves as the display screen 14, may be changed between the indirect viewing state in which the display device 13 is laid down and the direct viewing state in which the display device 13 is raised. For example, since indirect vision is relatively darker than direct vision, the controller MC may control the light amount of the backlight to be brighter than in direct vision. Conversely, direct vision may be controlled to be relatively darker than indirect vision.
In each of the above embodiments, an example of installing the radar detection device 10 on the dashboard D in the vehicle was given as an example of electronic equipment, but placing it in the vehicle or on the dashboard D is one example. Yes, it may be used as an electronic device other than an in-vehicle electronic device. Therefore, the light may be reflected from other than the front window FW of the vehicle. Further, the radar detection device 10 may be arranged in another position even inside the vehicle, for example, in the A pillar P shown in FIG.
- A light-emitting device other than the liquid crystal display, such as an organic electroluminescence (OEL) or an LED, may be used as the display screen 14 device.
The reflective plate 71 may be made of any material as long as it is transparent, and in addition to the above materials, for example, transparent plastics such as acrylic and polyester can be used.
The present invention can be freely implemented in a modified form without departing from the scope of the invention.

10... Radar detector as electronic information system, 14... Display screen, 71... Reflector plate as reflector, FW... Front window as reflector.
