         [0022]    In this case “the front” means the user side when looking at the instrument device  100  from front view, in other word the user recognizes vehicle information by looking at the instrument device  100  from front side. Also, “the back” means back side of “the front” (see the  FIG. 1   b ). “The upper side” means the user&#39;s head up side, and “lower side” means head down side. The left and right side of the user refer to “left” and “right” (see the  FIG. 1   a ). 
         [0023]    The instrument body  1  includes a circuit board  10 , a display device  20 , a pointer-type instrument  30 , a main case  40  and a dial plate  41 . 
         [0024]    The circuit board  10  is formed of a printed circuit board and the control unit  50  is mounted on. The circuit board  10  is formed of glass epoxy and a hole  10   a  that an axis of rotation of a motor  31  is formed. The control unit  50  drive controls the display device  20  and motor  31 , etc. according to signals (ex. vehicle speed data) supplied by ECU (Electric Control Unit)  60 . The detail of the control unit  50  will be explained later on. 
         [0025]    The display device  20  is a liquid crystal display that includes a TFT (Thin Film Transistor) type liquid crystal panel  21  and a back light  22  placed behind of the liquid crystal panel  21 , and display an image of notification information to a display area  20   a . The back light  22  illuminates the liquid crystal panel  21  transparently, and consists of a light guide plate and light source  22   a  such as Light Emitting Diode (LED). The display device  20  may be consisted of Organic Electro-Luminescence display. 
         [0026]    The pointer-type instrument  30  is consisted of the motor  31 , a pointer  32  rotated by the motor  31  and an indicating portion  410 . 
         [0027]    The motor  31  is, for example, a stepping motor and placed behind of the circuit board  10 . The motor  31  includes the rotation shaft  31   a  that extends from the back side of the circuit board  10  to the front side and passes through the hole  10   a . The motor  31  rotates the rotation shaft  31   a  controlled by the control unit  50 . 
         [0028]    The pointer  32  is mounted to the rotation shaft  31   a . The pointer  32  rotates on the surface of the dial plate  41  that is placed front side of the main case  40  and points the indicating portion  410 . The dial plate  41  and indicating portion  410  will be explained later on. The control unit  50  receives a speed data and rotates the rotation shaft  31   a  of the motor  31  according to the speed data. The pointer  32  is able to point the indicating portion  410  with preferable angle according to the speed data. The pointer type instrument  30  notifies the user vehicle speed by contrast of a movement of the pointer  32  over the indicating portion  410 . 
         [0029]    The main case  40  is made of synthetic resin, the circuit board  10  is mounted at the back side of the main case  40 , and the dial plate  41  is mounted at the front side of the main case  40 . 
         [0030]    The dial plate  41  is configured by forming the indicating portion  410  or the like on a plate-like substrate having a light-transmitting property. For example, the indicating portion  410  configured with a scales  411  and characters (including numbers)  412  of the dial plate  41  and is formed on the substrate. The indicating portion  410  is formed by, e.g., subjecting the substrate to a printing or painting or the like. For example, the indicating portion  410  is formed (in a so-called outline character shape) in such a way that the scales  411  and the characters  412  have a light-transmitting property and peripheries thereof have a light-shielding property. For example, as shown in  FIG. 1   a , the indicating portion  410  is formed in an arc shape around the rotation shaft  31   a . Further, the dial plate  41  is formed with a through hole  41   a  and a opening portion  42   b . The rotation shaft  31   a  passes through the through hole  41   a . The opening portion  42   b  is configured to allow the display area  20   a  of the display device  20  to be seen. 
         [0031]    The front case  2 , for example shown in  FIG. 1   a , consists of a transmitting member  2   a  and a shading case  2   b . The transmitting member  2   a , for example, is formed from visible light transparency glass or synthetic resin. The shading case  2   b , for example, is formed from hard blackish synthetic resin and shade light. The transmitting member  2   a  and the shading case  2   b  are fitted to each other by protrusions or the like provided in one or both thereof, thereby forming the front case  2 .) 
         [0032]    The back case  3 , for example, is formed from hard synthetic resin and formed in a front side open boxed shape. The front case  2  and the back case  3  are combined so as to sandwich the instrument body  1  by protrusions or the like provided in one or both thereof. 
         [0033]    Next, a configuration of the electrical structure of the instrument device  100  will be described in detail with reference to  FIG. 2 . There are the liquid crystal panel  21 , light source  22   a , motor  31 , ECU  60 , operation portion  70  and car navigation device  80  are electrically connected to the control unit  50 . 
         [0034]    The control unit  50  processes controlling of the instrument device  100 , and is connected to a microcomputer  51 , graphic display controller (GDC)  52 , motor  31 , liquid crystal display  21 , light source  22   a  with various wirings, and is consisted with various driver integrated circuit (not shown). 
         [0035]    The microcomputer  51  is provided with Central Processing Unit (CPU), Read Only Memory (RAM) and input/output interface. The microcomputer  51 , for example, CPU reads out curtain information which pre-stored in ROM and executes predetermined process (later described image transition process) by using pre-stored image data. RAM functions as a working memory upon CPU processes. The microcomputer  51  is electrically connected to ECU  60 , operation portion  70  and car navigation device  80 , and receives various information received from ECU  60 , operation portion  70  and car navigation device  80 . The microcomputer  51  executes process to control the instrument device  100  though electrically connected various drivers IC and GDC  52 . GDC  52  executes process to control display motion collaborating with the microcomputer  51 . GDC  52  is a controller that is able to draw both vector image and raster image (bitmap image). 
         [0036]    ECU  60  measures speed and remaining amount of fuel by sensors and supplies the data to the control unit  50 . 
         [0037]    The operation portion  70  is, for example, a sterling switch stored in a vehicle which the instrument device  100  is mounted in, and receives operation motions of user (driver) and supplies signals corresponding to the motions to the control unit  50 . In detail, the operation portion  70  is placed at the sterling so that the driver can operate while holding the sterling. The operation portion  70  includes upper bottom  70 U, lower bottom  70 D, left bottom  70 L and right bottom  70 R placed to surround a center point. The upper bottom  70 U is placed at upper side of the center point, the lower bottom  70 D is placed at lower side of the center point, the left bottom  70 L is placed at left side of the center point and the right bottom  70 R is placed at right side of the center point. Within those four bottoms, one bottom is pressed down by the driver&#39;s finger (for example a thumb) and an operation signal will be sent to the control unit  50 . In this embodiment, these bottoms will receive operation of transiting a certain image that is displayed in the display area  20   a.    
         [0038]    The car navigation device  80  is, for example, a car navigation device is mounted in the vehicle with the instrument device  100  is mounted and has audio function. The control unit  50  receives various information (vehicle operational information, audio information, etc.) from the car navigation device  80  and displays images (below, navigation image) that the car navigation device  80  should display to the display device  20  (display area  20   a ). In this case, the navigation image may be displayed as it is or changed partially. 
         [0039]    Next, a configuration of the image transition processing of the control unit  50  will be described in detail with reference to  FIGS. 4   a - 4   c ,  5   d - 5   g  and  6   a - 6   c . The control unit  50  stars processing image transition upon receiving a trigger of displaying the navigation image to the display device (the display area  20   a ) from the external car navigation device  80 . 
         [0040]    In this embodiment, an example of displaying an image shown in  FIG. 4   a  to the display area  20   a  is described. This displayed image includes a notification image  5  that notifies audio information displayed at position A1 of the display area  20   a . The notification image  5  notifies a name of music being played (or being selected) and information about the music (images of recorded album, length of the music). The notification image  5  is displayed based on the information inputted from the car navigation device  80  and is caused by the control unit  50  displaying at the display device  20 . The display image, in an area rather than the notification image  5  (left area of the figure), includes gear information (N, D, L, etc.) to notify where the gear is shifted and the fuel meter to notify remaining amount of fuel. These information is displayed on the display device  20  by the control unit  50  based on the information inputted from ECU  60 . 
         [0041]    The notification image  5 , shown in  FIG. 6   c , is configured with a content image  5   a  to display a content of the notification image  5  shown in  FIG. 6   a  (the information the notification image  5  must notify) and an outline image  5   b  to display an outline surrounding the notification image  5  shown in  FIG. 6   b . In this embodiment, the content image  5   a  is a raster image and the outline image  5   b  is a vector image. The  FIG. 4   a  describes the content image  5   a  and outline image  5   b  are positioned at the position A1. The meaning of positioning at the same position is that one of the coordination of the center of gravity is the same as the other coordination of the center of gravity and the user can recognize the two images are being at the same position. 
         [0042]      FIG. 4   a  shows that the display device  20  notifying and being displayed in the center of the display area  20   a . If the user desires to check other information rather than audio information (in this embodiment, the other information is displayed in the vacant display area that the notification image  5  was moved from the position A1), the upper bottom  70 U of the operation portion  70  is pressed. The signal according to the pressing the upper bottom will be sent to the control unit  50  and the control unit  50  will start the process of transiting the notification image  5 . 
         [0043]    First of all, the control unit  50  controls movement of the display device  20  and erases the content image  5   a  of the position A1. Specifically, as shown in  FIGS. 4   b  and  4   c , the content image  5   a  is gradually erased by fade-out animation. It should be noted that zoom-out animation (the content image  5   a  gradually reduce its size and converge at one point) can be used to erase the content image  5   a  as well. 
         [0044]    After the content image  5   a  is erased, the control unit  50  moves the outline image  5   b  from the position A1 to upper positioned A2. Specifically, as shown in order of  FIG. 4   c ,  FIGS. 5   d ,  5   e  and  5   f , the control unit  50  moves and gradually reduce its size of the vector image of the outline image  5   b  from A1 to A2. Continuously drawing the outline image  5   b  and finally displaying reduced size outline image  5   b  to the position A2 of the display device  20 . Not only changing shape of the outline image  5   b , but color and brightness also can be changed so that changes of displaying status so that the user can catch sensuously and better recognize that displaying status is changing (gradually changing color or brightness of the outline image  5   b  and blinking the outline image  5   b  etc.) 
         [0045]    The control unit  50  after transiting the outline image  5   b  to the position A2 (in other words, an outline image  5   b ′ is displayed at the position A2), and, as shown in order of  FIGS. 5   f  and  5   g , display a content image  5   a ′ which represent part of the content of the content image  5   a  that was displayed at the position A1. For one example described in figure, the content image  5   a ′ is displaying a name and number of currently played (or selected) music. Specifically, as shown in  FIGS. 5   f  and  5   g , the content image  5   a ′ is gradually moved out of the outline image  5   b ′ by fade-in animation. It should be noted that zoom-in animation (the content image  5   a  gradually expand its size and converge at one point) can be used to display the content image  5   a ′ as well. Also it should be noted that a timing when displaying the content image  5   a ′ can be at same time or slightly after the outline image  5   b  reaches the position A2. In this way, the notification image  5  positioned at the position A is configured with the content image  5   a ′ and outline image  5   b ′, and is changed to the notification image  5 ′ which share the same content with the notification image  5 . 
         [0046]    The control unit  50  also displays a notification image  6  to empty display area  20  where the notification image  5  was displayed and transited. This notification image  6  is, for example in  FIG. 5   g , an image of an average speed of a vehicle. This notification image  6 , same as the notification image  5 ′, is gradually displayed in fade-in animation or zoom-in animation, etc. 
         [0047]    The notification image  5 ′ displayed at the position A2 is displayed slightly less visible than the notification image  5  displayed at the position A1 (for example, the transparency of the notification image  5 ′ is higher than that of the notification image  5 ). Describing further, the notification image  6  to describe the average speed of the vehicle is more clearly visible than that of the notification image  5 ′ (the notification image  6  is brighter or brighter color). The reason for this is that the above process was enforced when the user prefers information rather than audio information (in a situation the user want to confirm the notification image  6  about average vehicle speed), a priority of displaying audio information should be less than a priority of displaying average vehicle speed information to meet the use&#39;s demand. 
         [0048]    On the other hand, if the user prefers the audio information, the display can be changed by operating the operation portion  70  in the opposite procedure. The user press down the lower bottom  70 D of the operation portion  70 , and the control unit  50  receive the signal of the lower bottom  70 D being pressed and transit the notification image  5 ′ of the position A2 to the position A1 as the notification image  5  in order of  FIG. 5   g ,  5   f ,  5   e ,  5   d ,  FIGS. 4   c ,  4   b  and  4   a.    
         [0049]    (Modification) 
         [0050]    Above explanation is for a predetermined image transiting inside of the display area  20   a . The instrument device  100  can display an image that was displayed in other display device can transited into the display area  20   a . An example will be explained. 
         [0051]    In this modification, an image displayed in the mobile terminal device  90  (for example, smart phone) in  FIG. 7  is displayed so as to be transited to the display device  20  of the instrument device  100 . The mobile terminal device  90  is well known so called mobile phone with talk function and web browser. The car navigation device  80  possibly communicates with the mobile terminal device  90  through wired or wireless network (in an example of wireless network, the car navigation device  80  and the mobile terminal device  90  are both Bluetooth compatible and paring models). The instrument device  100  can transit the image  8  of the mobile terminal device  90  to the display device  20  through the car navigation device  80 . 
         [0052]    In this modification, a display image being displayed in the display area  20   a  shown in  FIG. 8   a  is explained. In the condition shown in  FIG. 8   a  the display area  20   a  has no image of information notification. If the user wants to display a information of incoming phone call received by the mobile terminal device  90  to the display device  20 , the user can press down the left bottom  70 L of the operation portion  70 . Then, an operational signal corresponding to the left bottom  70 L will be sent to the control unit  50 , and the control unit  50  starts a process of displaying at least a part of the image  8  being transited to the display device  20 . 
         [0053]    The control unit  50  receives the operational signals and transits the outline (vector) image  7   b  that represent the outline of the final notification image  7  in order of  FIG. 8   b ,  8   c  and  FIG. 9   d  to the target position B from the end right portion of the display area  20   a . It is more effective that the color and brightness could been changed for the user to recognize the display has been changed (gradually changing the color and brightness). 
         [0054]    After transiting the outline image  7   b  to the target position B, the control unit  50  displays the content image  7   a  (raster image) which represent a part of the image was displayed in the mobile terminal device  90  to the target position B. The content image  7   a  is, for example, to notify there is an incoming call from a particular person. More specifically, the control unit  50  display a part of the content image  7   a  moves into inside of the outline image 7   b  by the fade-in animation. In this case a part of the content image  7   a  can be protruding from the outline image  7   b  (see  FIGS. 9   e  and  9   f  “In Coming Call”). It should be noted that the content image  7   a  can be gradually displayed by zoom-in animation (for example, the content image  7   a  expands gradually from one point). The content image  7   a  can be displayed at the same time or immediately following as the outline image  7   b  reaches to the target position B. In this way, the image  8  displayed at the mobile terminal device  90  is configured with the content image  7   a  and outline image  7   b , and the user can recognize as if the image  8  was changed to the notification image  7  that shares a part of the content of the image  8 . 
         [0055]    On the other hand, if the user desires to delete the information regarding to the mobile terminal device  90  from the display device  20  due to finishing of the phone call, opposite procedure of the above mentioned procedure will be followed in order of  FIG. 9   f ,  9   e ,  9   d ,  FIG. 8   c ,  8   b ,  8   a . In particular, when the user presses down the right bottom  70 R of the operation portion  70  and the control unit  50  receives the control signal regarding the action to the right bottom  70 R, the control unit  50 , described in  FIGS. 9   f  and  9   e , gradually erases the content image  7   a  displayed at the target position B by fade-out animation or zoom-out animation. The control unit  50  also frame-out the outline image  7   b  from the target position B to right end portion. It is effective to change the color and brightness of the outline image  7   b.    
         [0056]    According to the above described image transition process modification, the control unit  50  not only can starts the process of displaying the notification image  7  due to receiving the signal sent from the operation portion  70 , but also starts the process of displaying the notification image  7  in response to receiving a signal from the mobile terminal device  90  through the car navigation device  80  that there is a incoming phone. Regardless of operated by the user, the control unit  50  can erase the notification image  7  in response to receiving a signal of finishing the phone call. 
         [0057]    According to the instrument device  100  according to the embodiment and its modified examples described above, rather than the image showing the content of the notification image, subsequent to moving the image showing the outline of a notification image (outline image) for displaying the notification image including the content image, the user can recognize a predetermined image as it is moving. It is possible to reduce the load on the user, since it is an outline image showing the outline (border), appearance of the moving image does not become coarse. 
         [0058]    Since it is a vector image, the outline image has the following advantages. 
         [0059]    As in the prior art, when an attempt to move a predetermined image by animation using raster image, the image of the moving object is increased for each image to be moved, it is necessary to prepare the image data for animation and the and storage capacity of the storage means such as ROM is increased. Since large image resolution data is large in its amount, it takes time to transit, and it is not reproduced as smooth animation. In order to control the display quality, high control unit of computing power was required. 
         [0060]    On the other hand, the outline image of the instrument device  100  is a vector image and expresses the movement of the image. Because it is generated in real time based on the coordinate data, it is possible to reduce the amount of data, and storage capacity the storage means needed is relatively small. Furthermore, by simply changing the number, etc., of the vector image, it is possible to move the outline image and alter the outline of the shape and color and brightness. 
         [0061]    In the above embodiments, it is difficult to visually recognize the content image  5   a ′ than the content image  5   a , and thereby easier to visually recognize the content image  5   a  (the notification image  6  and the content image  5   a  also follow the same principle). Thus, if the priority of notified information is decreased, it is subjected to a cryptocrystalline treatment, and if the priority is increased in reverse, it is subjected to a significant treatment, this also makes it possible to reduce the load on the user&#39;s information recognition since information can be appropriately notified to the user. 
         [0062]    In the above embodiments and variations, the content image  5   a ,  5   a ′,  7   a  erased gradually, and also, it is made to gradually display the content images. Because it is said that instrument viewing time of the driver is the average 0.3 seconds, the erasing or sudden movement of the image confuse the driver, and it would be the extra information recognized by the driver. However, the instrument device  100  is possible to eliminate or reduce such a road by displaying and erasing the image gradually as described above. Furthermore, by gradually performing as it is possible to feel like the content image and the outline image is smoothly linked, more effectively and smoothly a predetermined image can be displayed as it is moving. 
         [0063]    Further, the instrument device  100 , the operation direction of the operation portion  70  and the moving direction of the outline image (the moving direction of the notification information) is corresponding (From the position A1, when moving the image to the right of the position A2 than the position A1, pressing the right bottom  70 R located on the right side of the operation portion  70 ). Thus, since the image is moved in accordance with the request of the user, without having to violate the user&#39;s predictions, it is user friendly, also, it is possible to reduce the load of information cognition. 
         [0064]    The invention is not intended to be limited by the embodiments, the variant, and the drawings. Within changing the gist of the present invention, it is possible to make appropriate changes. Below an example is shown. 
         [0065]    In the above description, the vehicle display device is an instrument device  100 , although the instrument device  100  is an example which can display information for the car navigation device  80 , vehicle display device may be a car navigation device itself. In this case, the control unit of the car navigation device  80  to perform the same image moving process as above. 
         [0066]    Also, the instrument device  100  without passing through the car navigation device  80 , and may be able to communicate directly with the mobile terminal device  90 . 
         [0067]    Furthermore, the notification image of a moving object (moving object) displayed on the display area  20   a , it is needless to say that it is not limited to audio information. It may be a notification image indicating the back monitor image or the like. 
         [0068]    In addition, external image does not have to be a vector image, may be a raster image. However, the vector image is preferred because it can reduce the amount of data required. Also, content image is, not only raster image, are configured from the raster image and the vector image. 
         [0069]    Moreover, outline image to be actually moved (an example of a graphic image) is not limited to the outline of the content image. It may be a graphic image consisting of other shapes. For example, after moving the lines and other shapes such as a track and display the notification image of the object to be moved, it is also possible to feel as the content image moved. In other words, as long as the user feels the movement of the notification images, graphics are not limited to those showing an outline of the notification image. In this case, graphic images to be actually moved, it is preferably a vector image. 
         [0070]    Moreover, the notification image after and before the movement may be displayed to be one may also include the other, (the portion constituting one of the notification image contained in the other notification image), one and the other may be the same. In other words, the content of the notification image after the movement and before the movement, it is sufficient that at least partially common. 
         [0071]    The operation portion  70  is not limited the steering switch. Various control switches near the instrument panel, a known operating unit such as an input means having a touch panel for accepting gesture operation may be used. Also in this case, it is preferable that the operation direction for accepting the operating portion and the moving direction of the outline image (direction in which the notification image is moving) is compatible. 
         [0072]    In the above description, in order to facilitate the understanding of the present invention, the description of the known technical matters that are not important as appropriate is omitted. 
       INDUSTRIAL APPLICABILITY 
       [0073]    The invention, for example, a display device mounted on a vehicle, can be applied as an instrument can reduce the load of the user information recognition.
