In addition to the movement to the (second position), the first indicator 1 is displayed so that the indicator portion 1a and the background portion 1b of the image move according to the movement of the pointer 2a and the display partition portion 2c3. Further, when the image is moved, the microcomputer 10 moves the first display 1 to move the unclear image 1d in which at least part of the image is unclear from the display position of the image in a direction opposite to the moving direction D1 of the image. Is displayed at a position shifted in the pre-movement direction D2. FIG. 8 shows a display example in which the unclear background portion in which the background portion 1b is unclear as the unclear image 1d is displayed with a predetermined amount shifted from the background portion 1b. FIG. 8 shows only the indicator 1a and the background 1b corresponding to the second display 2 (speedometer) on the right side, but corresponds to the second display 2 (rotometer) on the left side. Similarly, the unclear image 1d is displayed for the index portion 1a and the background portion 1b. The blurred image 1d is drawn so that the background portion 1b is different from the background portion 1b by making at least one of density, luminance, hue, or saturation different from that of the background portion 1b. In this case, the background portions 1b are displayed side by side so as to become gradually unclear (a gradation) toward the pre-movement direction D2. When the microcomputer 10 shifts from the second display form to the first display form, the microcomputer 10 places the support member 2c having the pointer 2a and the display partition part 2c3 on the moving mechanism 4 at both end positions (first position). ) To the center position (second position), and the indicator portion 1a and the background portion 1b of the image are moved according to the movement of the pointer 2a and the display partition portion 2c3 on the first display 1.

Display at a position shifted to.

  When the second display 2 and the image on the first display 1 are moved in synchronization, the afterimage of the image follows the display partition 2c3 by displaying the unclear image 1d. Even if the position of the display partition 2c3 of the second display 2 and the display position of the image are not completely synchronized, the user is recognized by the presence of the afterimage. It becomes difficult to eliminate the uncomfortable feeling and improve the visibility and appearance when moving. In particular, when the display partition portion 2c3 is made translucent and the background portion 1b is displayed on the first display 1 so as to overlap the display partition portion 2c3, the difference between the display partition portion 2c3 and the background portion 1g is recognized by the user. Although it is easy to be performed, it is preferable that the unclear background portion adjacent to the background portion 1b is displayed as the unclear image 1d, thereby reducing the user's uncomfortable feeling and improving the visibility and appearance. For the index part 1a, it is desirable not to display the unclear image 1d corresponding to the index part 1a when emphasizing the legibility of the index and numbers. However, when emphasizing the presentation effect, the index part 1a is not displayed. In addition, by displaying a blurred image, the movement of the image can be emphasized, and the merchantability as an instrument device can be improved.

  The present invention is applicable to an instrument device provided with a display device called a flat panel display such as a liquid crystal display panel.
