  Hereinafter, the display device according to the present embodiment will be described with reference to the drawings. The display device of this embodiment is applied to a graphic meter installed on an instrument panel in a vehicle compartment.

  FIG. 1 shows an example of the hardware configuration of the graphic meter 100 of this embodiment. As shown in FIG. 1, the graphic meter 100 includes a microcomputer (CPU: Central Processing Unit) 101, a read-only memory (EEPROM) 102, an interface 103, an interface 104, a CPU power supply unit 105, a graphic A controller 106, a frame memory 107, an X driver 108, a Y driver 109, an LCD (Liquid Crystal Display) power supply unit 110, and a liquid crystal display (TFT-LCD: Thin Film Transistor Liquid Crystal Display) 111 are provided.

  A microcomputer (CPU) 101 is a control unit, and executes various programs necessary for realizing the functions of the graphic meter 100 by executing a program prepared in advance. For example, the microcomputer 101 performs the process shown in the flowchart of FIG.

  The read-only memory 102 stores the contents of a program executed by the microcomputer 101, annular display elements 71, 72, 81, 82 described later, and meter images (a speedometer 41, a fuel gauge 42, a tachometer 51, and a water temperature gauge 52. Image data, etc., and various fixed data.

  The interface 103 inputs a signal (IGN +) indicating the state of the ignition switch on the vehicle side to the microcomputer 101.

  The interface 104 is used to perform communication according to a CAN (Controller Area Network) standard between the microcomputer 101 and various control devices (ECU: Electric Control Unit) on the vehicle side. Specifically, data representing various current vehicle conditions such as the current vehicle running speed, engine rotation speed, cooling water temperature, fuel amount, and whether or not the clutch is connected is transmitted from the vehicle side to the interface 104 as almost real-time data. To the microcomputer 101.

  For example, the interface 104 receives a vehicle speed pulse signal output from a speed sensor mounted on the vehicle side every time the vehicle moves by a predetermined amount, and the microcomputer 101 as travel speed information indicating the current travel speed value of the vehicle. Output to.

  The interface 104 receives a pulse signal output from an engine speed sensor that detects the engine speed, and outputs the pulse signal to the microcomputer 101 as engine speed information. The interface 104 receives information on the fuel amount detected by the fuel sensor and outputs the information to the microcomputer 101. The interface 104 receives a signal from a water temperature sensor that detects the temperature of the cooling water in the radiator, and outputs the signal to the microcomputer 101 as cooling water temperature information.

  The interface 115 is connected to a switch (for example, a steering switch) for instructing an operation related to a graphic screen displayed on the liquid crystal display 111, receives an operation instruction from the user, and outputs it to the microcomputer 101. The interface 115 accepts various data such as video data and navigation image data captured by the camera and outputs them as image information to the microcomputer 101.

  The CPU power supply unit 105 inputs DC power supplied from the vehicle-side plus-side power supply line (+ B) and generates a DC voltage (Vcc) necessary for the operation of the microcomputer 101. Further, a reset signal is generated as necessary, and an operation for suppressing power supply is performed in accordance with a sleep signal output from the microcomputer 101.

  The liquid crystal display 111 is a display unit, and has a color two-dimensional display screen in which a large number of minute display cells constituted by liquid crystal devices are arranged in the X direction and the Y direction. By individually controlling the display states of a large number of minute display cells for each cell, desired information such as graphics, characters, images, etc. can be displayed on the two-dimensional display screen.

  Thus, the liquid crystal display 111 displays the graphic display screen 111a of the graphic meter 100 by two-dimensional screen display. The display content of the liquid crystal display 111 is controlled by the microcomputer 101 as will be described later.

  The scanning position in the Y direction on the display screen of the liquid crystal display 111 is sequentially switched by the output of the Y driver 109. The Y driver 109 sequentially switches the scanning position in the Y direction in synchronization with the vertical synchronization signal output from the graphic controller 106.

  The X driver 108 sequentially switches the scanning position in the X direction on the display screen of the liquid crystal display 111 in synchronization with the horizontal synchronization signal output from the graphic controller 106. Further, the X driver 108 gives the RGB color image data output from the graphic controller 106 to the display cell at the scanning position to control the display content on the screen.

  The graphic controller 106 displays various graphic elements on the screen of the liquid crystal display 111 according to various instructions input from the microcomputer 101. Actually, the microcomputer 101 or the graphic controller 106 writes the display data to the frame memory 107 that holds the display contents for each pixel and draws the graphic. In addition, a vertical synchronizing signal and a horizontal synchronizing signal for two-dimensionally scanning the screen of the liquid crystal display 111 are generated, and display data stored at a corresponding address on the frame memory 107 at a timing synchronized with these synchronizing signals. Is applied to the liquid crystal display 111.

  The LCD power supply unit 110 receives DC power supplied from the vehicle-side plus power supply line (+ B) and generates predetermined DC power required for display on the liquid crystal display 111.

  FIG. 2 is a diagram showing a graphic display screen 111a displayed on the liquid crystal display 111 of the graphic meter 100 when the graphic meter 100 is in a normal display state. A speedometer 41, a fuel gauge 42, a tachometer 51, a water temperature gauge 52, and a vehicle image 61 are displayed on the graphic display screen 111a shown in FIG. Each of these display elements is realized as a graphic display element expressed by a set of a large number of display pixels.

  The speedometer 41 (first display element) is a circular display element for presenting the current traveling speed (vehicle speed: km / h) as information relating to the state of the vehicle. In the present embodiment, the speedometer 41 is disposed in the vicinity of the annular speed scale 45 and the center of the speed scale 45 as in a general analog instrument, and indicates a part of the speed scale 45 to indicate the current vehicle speed. And a pointer 46 to be presented. As shown in FIG. 2, the speedometer 41 is disposed on one end side (left end side in the figure) of the graphic display screen 111a.

  The fuel gauge 42 (third display element) is a circular display element for presenting the current fuel remaining amount of the vehicle as information relating to the state of the vehicle. In this embodiment, the fuel gauge 42 is arranged in the vicinity of the center of the fuel scale 47 and the annular fuel scale 47 having a smaller diameter than the speed scale 45, as in a general analog instrument. And a pointer 48 indicating a part and presenting the current remaining fuel amount. As shown in FIG. 2, the fuel gauge 42 is closer to the tachometer 51 than the speedometer 41 so that the graphic display screen 111 a overlaps with the speedometer 41 (that is, the center side, the other end side). To be arranged.) In addition, the fuel gauge 42 is not displayed in the overlapping portion, and the speedometer 41 is displayed.

  The tachometer 51 (first display element) is a circular display element for presenting the current engine speed (x1000 rpm) as information relating to the state of the vehicle. In the present embodiment, like a general analog instrument, the tachometer 51 is disposed in the vicinity of the center of the rotation speed scale 55 and the rotation speed scale 55 having the same shape as the speed scale 45 and the rotation speed scale 55. A pointer 56 indicating a part of the speed scale 55 and presenting the current rotation speed is included. As shown in FIG. 2, the tachometer 51 is opposed to the speedometer 41 on the other end side (right end side in the figure) opposite to the one end side where the speedometer 41 is arranged on the graphic display screen 111 a. Has been placed.

  The water temperature meter 52 (third display element) is a circular display element for presenting the current coolant temperature of the vehicle as information relating to the state of the vehicle. In the present embodiment, the water temperature gauge 52 is arranged in the vicinity of the center of the water temperature scale 57 and the annular water temperature scale 57 having substantially the same shape as the fuel scale 47 in the same manner as a general analog instrument. And a pointer 58 that indicates a part of the current temperature and presents the current temperature of the cooling water. As shown in FIG. 2, the water temperature meter 52 is closer to the speedometer 41 than the tachometer 51 (that is, to the center side and one end side) so as to have a portion overlapping the tachometer 51 on the graphic display screen 111a. .) Is arranged. In addition, the water temperature meter 52 is not displayed in the overlapping portion, and the tachometer 51 is displayed.

  The vehicle image 61 is a display element that simulates the overall shape of the vehicle, and is arranged at the center of the screen in the graphic display screen 111a shown in FIG. That is, the vehicle image 61 is arranged between the speedometer 41 and the fuel gauge 42 arranged on one end side, and the tachometer 51 and the water temperature gauge 52 arranged on the other end side. The vehicle image 61 can be used, for example, to represent the current state of the vehicle graphically rather than displaying numerical values.

  Further, as will be described later, when the display is started before the graphic meter 100 transitions to the normal display state, a circular (annular) display imitating the outer shape of the speed scale 45 is displayed on the graphic display screen 111a. Element 71 (second display element), circular display element 72 simulating the outer shape of fuel scale 47 (fourth display element), and circular display element 81 simulating the outer shape of rotation speed scale 55 (second And a circular display element 82 (fourth display element) simulating the outer shape of the water temperature scale 57 is displayed (see FIGS. 4A and 4B). Details of display contents at the start of the display will be described later.

  FIG. 3 is a flowchart showing a processing procedure at the start of display of the graphic meter 100 shown in FIG. FIG. 4 is a diagram showing a transition of the graphic display screen 111a displayed on the liquid crystal display 111 of the graphic meter 100 at the start of display.

  That is, when the microcomputer 101 starts the display of the graphic display screen 111a by executing the processing procedure shown in FIG. 3, the display contents are sequentially changed as shown in FIG. That is, first, the display state shown in FIG. 4A is obtained, and the display contents change as shown in FIGS. 4B and 4C as time elapses.

  A processing procedure of the microcomputer 101 shown in FIG. 3 and a specific change in display contents on the graphic display screen 111a will be described below. In the processing procedure described below, the microcomputer 101 controls the liquid crystal display 111 to explain the contents of the processing for changing the display content of the liquid crystal display 111. However, the description is simplified and understood. For the sake of simplicity, the microcomputer 101 may be described in a simplified manner that the display content is changed (or changed).

  The microcomputer 101 waits until an ignition switch (IGN +) signal is input by turning on the ignition switch by the driver (step S1). When an ignition-on signal is input through the interface 103, the microcomputer 101 starts displaying various information on the liquid crystal display 111.

  The microcomputer 101 reads the image data of the annular display elements 71 and 81 stored in the EEPROM 102, and the predetermined range 75 (the range defined by the dotted line L1) and the predetermined range 85 (the dotted line L2) of the graphic display screen 111a. The starting positions s within the range are determined irregularly (randomly), and the annular display elements 71 and 81 are arranged at the starting positions s (step S2). At this time, as shown in FIG. 4A, the display elements 71 and 81 are displayed in a predetermined initial shape. Similarly, the microcomputer 101 reads the image data of the annular display elements 72 and 82 stored in the EEPROM 102, and the predetermined range 76 (range defined by the dotted line L3) and the predetermined range 86 (dotted line) of the graphic display screen 111a. The start positions s within the range defined by L4 are determined irregularly, and the annular display elements 72 and 82 are arranged at the start positions s (step S2). At this time, as shown in FIG. 4A, the display elements 72 and 82 are displayed in a predetermined initial shape. FIG. 4A shows display elements 71, 72, 81, 82 displayed in a predetermined initial shape at a start position s within a predetermined range 75, 76, 85, 86. At this time, as shown in FIG. 4A, the display elements 72 and 82 are displayed in the overlapping portions of the display elements 71 and 81 and the display elements 72 and 82.

  Here, the predetermined ranges 75, 76, 85, 86 are set as ranges (setting ranges) in which the annular display elements 71, 72, 81, 82 are movable.

  Then, the microcomputer 101 continuously moves the annular display elements 71, 72, 81, and 82 along the irregular path m from the start position s to the set position e that is the arrival point (step S3). Step S4). Further, during the movement, the microcomputer 101 displays the display elements 71, 72, 81, 82 from the initial shape shown in FIG. 4A to the set shape shown in FIG. 4B according to an irregular shape change pattern. Are continuously changed (step S3, step S4). Further, during the movement, the microcomputer 101 gradually increases these densities from the initial density to a predetermined density that is arbitrarily set (steps S3 and S4). Here, the set position e is a display position where each meter image (speedometer 41, fuel gauge 42, tachometer 51, water temperature gauge 52) is displayed in a normal state. Further, the set shape is the outer shape of each scale (speed scale 45, fuel scale 47, rotational speed scale 55, water temperature scale 57) of each meter image (speed meter 41, fuel meter 42, tachometer 51, water temperature meter 52). It is the shape used as a substantially identical external shape. If the display elements 71, 81 and the display elements 72, 82 have overlapping portions while the annular display elements 71, 72, 81, 82 are moving, the display elements 72, 82 are included in the overlapping portions. Is displayed. That is, the display elements 71 and 81 and the display elements 72 and 82 are displayed so as to be visually recognized by the user so that the display elements 72 and 82 are positioned on the front side.

  As a method of irregularly determining the start position s within the predetermined ranges 75, 76, 85, and 86, various known methods can be applied. For example, there is a method in which a value obtained by using a random number generation function is associated with the coordinates of the graphic display screen 111a and set as the start position s in each of the predetermined ranges 75, 76, 85, 86. Further, the coordinates of the start position s may be fixed values registered in advance, or may be arbitrarily selected from a plurality of coordinates registered in advance.

  Here, the start positions s of the annular display elements 71, 72, 81, 82 are set within the predetermined ranges 75, 76, 85, 86, respectively, but are not limited to these predetermined ranges. It is also conceivable to set at any position in the graphic display screen 111a.

  In addition, the irregular path m, which is a path that the display elements 71, 72, 81, and 82 move from the start position s to the set position e that is the arrival point, is displayed for each display element by the following method, for example. It is determined. The pattern of the irregular path m is defined as a curve composed of various continuous functions passing through the coordinates of the start position s and the coordinates of the set position e. As the curve, a Bezier curve, an involute curve, a spline curve, a quadratic curve (circle, ellipse, hyperbola, parabola), a primary curve (straight line), or the like can be selected. A plurality of functions representing these curves are numbered in advance and registered in the memory, and a path m is determined using functions and parameters corresponding to values obtained using a random number generation function.

  Further, when determining the route m, the user draws or selects a plurality of routes in advance or registers them in the memory without using a function, and selects them appropriately from the plurality of registered routes. The route m may be determined by

  In the above embodiment, each of the pattern of the start position s and the path m is determined separately. However, a plurality of combinations of the pattern of the start position s and the path m are registered in advance, and Alternatively, the route m may be determined by randomly selecting one combination. In this case, the time required for the processing of the microcomputer 101 can be reduced.

  Further, the irregular shape change pattern that defines the pattern in which the shape of the display elements 71, 72, 81, and 82 changes from the initial shape to the set shape is determined for each display element by the following method. Is done. For example, as a parameter for determining the shape, size, inclination (inclination in the display surface, inclination in the depth direction with respect to the display surface), and the like are determined in advance. Then, a continuous change pattern of each parameter is determined in association with a value obtained using a random number generation function, and the shape is changed according to this. The deformation of the shape can be realized by performing processing for adjusting the magnification, aspect ratio, rotation, opacity, and the like on the original image registered in the EEPROM 102. For example, in the example of the initial shape shown in FIG. 4A, each of the annular display elements 72, 81, and 82 is shown with a different aspect ratio, and is displayed as a slightly flat elliptical shape.

  FIG. 3B shows the annular display elements 71, 72, 81, 82 after moving along the irregular path m and the shape becomes the set shape. Since the length of the path m is different for each of the annular display elements 71, 72, 81, and 82, when the movement time is a fixed value, the movement speed of the annular display element with the longer path m is higher. On the other hand, when the movement speeds of all the annular display elements are set to be the same, the time required to reach the annular display element having the longer path m is longer. In the present embodiment, both can be supported. Further, different moving speeds may be set in advance for each annular display element, and it is expected that the movement is more irregular.

  Subsequent to step S4, the microcomputer 101 changes the darkness of the annular display elements 71, 72, 81, 82 that have reached the set position e so as to be lightened (step S5). The microcomputer 101 displays each meter image registered in the EEPROM 102 so as to overlap with the thin annular display elements 71, 72, 81, 82 (step S6). That is, as shown in FIG. 3C, a speedometer 41, a fuel gauge 42, a tachometer 51, and a water temperature gauge 52 are displayed as meter images.

  Thereafter, the microcomputer 101 erases the annular display elements 71, 72, 81, 82 (step S7). The microcomputer 101 starts display control for changing the display of the pointers included in the meter image based on the vehicle data input from the interface 104 such as travel speed, engine speed, fuel amount, and coolant temperature. (Step S8). Thereafter, the microcomputer 101 ends the operation at the start of display, and makes the graphic meter 100 transition to the normal display state.

  By the processing described above, at the start of display, the annular display elements 71, 72, 81, 82 change in shape from the initial shape to the set shape according to the shape change pattern randomly determined by the microcomputer 101. The microcomputer 101 is displayed so as to continuously move from the start position s to the set position e along the path m determined at random (steps S3 and S4). After the movement, the speedometer 41 and the tachometer 51 are displayed at the set position e instead of the display elements 71, 72, 81, 82 displayed at the set position e (steps S6 and S7). Further, when the speedometer 41, the fuel gauge 42, the tachometer 51, and the water temperature gauge 52 are displayed in place of the display elements 71, 72, 81, 82, their outer shapes are substantially the same. With the above configuration, at the start of display, the user's line of sight is guided to display elements 71, 72, 81, 82 that move randomly, and the user displays the speedometer 41, fuel gauge 42, The tachometer 51 and the water temperature gauge 52 are visually recognized. Therefore, according to the meter unit 100 according to the embodiment, even in the case where the display form similar to that of a general analog meter is employed as shown in FIG. Depending on the display mode, the user can feel that the meter is a highly functional meter completely different from the analog meter.

  In this embodiment, after the meter image is displayed, the thin annular display elements 71, 72, 81, and 82 are erased. However, the thin annular display element becomes a part of the meter image. In addition, a meter image may be displayed inside. Alternatively, the annular display elements 71, 72, 81, and 82 are respectively attached to the outer frame of the speedometer 41, the fuel gauge 42, the tachometer 51, and the water temperature gauge 52 (that is, the speed scale 45, the fuel scale 47, and the rotation speed scale). 55, a part of the water temperature scale 57) may be a display element having the same shape. Thereby, the transition to the meter image is performed with a smoother display.

  Below, the effect | action and effect of the display apparatus which concern on this embodiment are demonstrated.

The graphic meter 100 (display device) according to the present embodiment includes a liquid crystal display 111 (display unit) capable of displaying an arbitrary image by combining a large number of pixels whose display forms can be individually controlled, and a liquid crystal display 111. A microcomputer 101 (control unit) that executes various controls including control of display contents, and can display information related to the state of the vehicle (vehicle speed, fuel remaining amount, engine rotation speed, cooling water temperature). Device. When the graphic meter 100 is in a normal display state, the liquid crystal display 111 presents a circular speedometer 41 (first display element) for presenting the vehicle speed and an engine rotational speed. The circular tachometer 51 is displayed at a predetermined display position (set position e). In addition, the liquid crystal display 111 starts from the start position s (movement start position) to the set position e along the path m randomly determined by the microcomputer 101 at the start of display before the graphic meter 100 transitions to the normal display state. The circular display elements 71 and 81 (second display elements) are displayed so as to move continuously, and then the speedometer 41 and the tachometer are substituted for the display elements 71 and 81 displayed at the set position e. 51 is displayed at the set position e.
Thereby, the gaze position of the user is guided to the speedometer 41 and the tachometer 51 at the start of display by the display elements 71 and 81 that move at random. For this reason, the user can be prompted to see these instruments at the start of operation (ie, at the start of display). Moreover, since the movement of the display elements 71 and 81 is irregular, a display rich in change can be realized, and a novel impression different from a general analog meter can be given to the user.

Furthermore, in the graphic meter 100 according to the present embodiment, the outer shape of the speedometer 41 and the tachometer 51 and the display elements 71 and 81 is displayed when the speedometer 41 and the tachometer 51 are displayed instead of the display elements 71 and 81. Are substantially the same.
For this reason, it is easy to make a user recognize the change of the display mode at the time of a display start as a series of changes. For this reason, a display with little discomfort can be realized.

Further, in the graphic meter 100 according to the present embodiment, the liquid crystal display 111 has a portion that overlaps with the speedometer 41 and the tachometer 51 when the graphic meter 100 is in a normal display state. A circular fuel gauge 42 (third display element) for presenting the remaining amount of fuel on which the speedometer 41 and the tachometer 51 are displayed, and a circular water temperature gauge 52 for presenting the temperature of the cooling water. (Third display element) is displayed at the set position e (another predetermined display position). The liquid crystal display 111 displays substantially circular display elements 72 and 82 so as to continuously move from the start position s to the set position e along the path m randomly determined by the microcomputer 101 at the start of display. (Fourth display element) is displayed, and then the fuel gauge 42 and the water temperature gauge 52 are displayed at the set position e instead of the display elements 72 and 82 displayed at the set position e. When the display elements 72, 82 are moving, and the display elements 72, 82, the fuel gauge 42, and the water temperature gauge 52 have overlapping portions, the liquid crystal display 111 has the display elements 72, 82 in the overlapping portions. Is displayed.
As a result, during normal display, a part of the fuel gauge 42 and the water temperature gauge 52 is displayed behind the speedometer 41 and the tachometer 51, whereas when the display starts, the display is displayed on the speedometer 41 and the tachometer 51. In front of the display elements 71 and 81 that should be replaced, display elements 72 and 82 that should be replaced by the fuel gauge 42 and the water temperature gauge 52 are displayed. That is, the speedometer 41, the tachometer 51 and the display elements 71 and 81, and the fuel gauge 42, the water temperature gauge 52 and the display elements 72 and 82 are displayed so that the overlapping order is different between the normal display time and the display start time. Is done. For this reason, a more novel impression can be given to the user.

In the graphic meter 100 according to the present embodiment, the liquid crystal display 111 has a circular speedometer 41 (first display element) for presenting the vehicle speed when the graphic meter 100 is in a normal display state. And a circular tachometer 51 for presenting the rotational speed of the engine is displayed in a predetermined shape (set shape) at a predetermined display position (set position e). The liquid crystal display 111 changes its shape from the initial shape to the set shape according to the shape change pattern randomly determined by the microcomputer 101 at the start of display before the graphic meter 100 transitions to the normal display state. The circular display elements 71 and 81 (second display elements) are displayed so as to continuously move from the start position s (movement start position) to the set position e, and then displayed at the set position e. Instead of the display elements 71 and 81, the speedometer 41 and the tachometer 51 are displayed at the set position e.
Thereby, the gaze position of the user is guided to the speedometer 41 and the tachometer 51 at the start of display by the display elements 71 and 81 whose shapes change at random. For this reason, the user can be prompted to see these instruments at the start of operation (ie, at the start of display). In addition, since the change in the shape of the display elements 71 and 81 is irregular, a display rich in change can be realized, and a novel impression different from a general analog meter can be given to the user.

  The technical scope of the present invention is not limited to the embodiment described above. The above-described embodiments can be accompanied by various modifications and improvements within the technical scope of the present invention.

  For example, in the above-described embodiment, the two display devices, the speedometer 41 and the tachometer 51, are displayed to face each other as the first display element, but any one of these is displayed. It does not matter. Moreover, you may be the structure by which this other instrument is displayed as a 1st display element. The same applies to the third display element. Further, the third display element may not be displayed.

  Moreover, in the said embodiment, the speedometer 41 which is the 1st display element, the tachometer 51, the display elements 71 and 81 which are the 2nd display element, the fuel gauge 42 which is the 3rd display element, the water temperature gauge 52, Although the display elements 72 and 82 as the fourth display element are both configured to be circular, they may be substantially circular, for example, elliptical. For example, the speedometer 41 and the tachometer 51 may have a configuration having an elliptical outer shape. However, it is possible to enhance the sense of unity as a whole by unifying the meter images and the annular display elements 71, 72, 81, 82 with a circular outer shape.

  In the above-described embodiment, the shape and shading of the annular display element are changed by image processing for adjusting the magnification, aspect ratio, rotation, opacity, and the like. A configuration in which the shape and shading are changed using a plurality of different images may be used.

  Further, in the above embodiment, the display elements 71 and 81 change the shape from the initial shape to the set shape according to the shape change pattern randomly determined by the microcomputer 101, and the path m determined by the microcomputer 101 at random. Are displayed so as to continuously move from the start position s to the set position e (step S3, step S4), but the shape does not change during the movement, and the set shape (initial shape) The configuration may be such that the microcomputer 101 is displayed so as to continuously move from the start position s to the set position e along the path m determined at random. Alternatively, the movement path of the display elements 71 and 81 is not determined at random, and the shape changes from the initial shape to the set shape according to the shape change pattern randomly determined by the microcomputer 101, along the predetermined path, It may be configured to be displayed so as to continuously move from the start position s to the set position e. However, a more novel display can be obtained by adding randomness to both the path and the shape change pattern.

  Further, in the above embodiment, at the time when the speedometer 41 and the tachometer 51 are displayed instead of the display elements 71 and 81, the outer shapes of the speedometer 41 and the tachometer 51 and the display elements 71 and 81 are substantially the same. Although a certain configuration is adopted, the outer shapes of the speedometer 41 and the tachometer 51 and the display elements 71 and 81 may be different at that time.

  Moreover, in the said embodiment, after changing the darkness of the cyclic | annular display element 71, 72, 81, 82 thinly by step S5, each meter image is displayed by step S6, and cyclic | annular display element 71, step S7, 72, 81, and 82 are deleted, but other display modes can be used as long as each meter image is displayed in place of the annular display elements 71, 72, 81, and 82. It does not matter. For example, the display of each of the meter images may be switched instantaneously with the annular display elements 71, 72, 81, 82 without changing the darkness of the annular display elements 71, 72, 81, 82.
