That is, the display source 2 and the reflection member 3 are disposed so as to face each other in the housing case 10. In the best mode, the case where one reflecting member 3 is provided will be described in order to simplify the description. However, the present invention is not limited to this, and a plurality of reflecting members 3 are provided to provide display light. Various embodiments can be made such that L is reflected a plurality of times, and the display light L is directly projected onto the windshield 101 without using the reflecting member 3.

  As shown in FIG. 3 or the like, the vehicle width direction moving means 4 includes a base member 41, a drive unit 42, a transmission unit 43, a guide unit 44, and a movement amount detection unit 45, and accommodates them. The case 10 is housed and configured.

  The drive unit 42 uses various motors and the like, and is electrically connected to the control unit 6. The drive unit 42 is provided with a gear 42 a at a rotatable output unit, and has a structure in which the gear 42 a rotates in an arbitrary rotation direction under the control of the control unit 6. The transmission unit 43 has a plurality of teeth that mesh with the gear 42a, and has a structure that transmits the power of the drive unit 42 to the base member 41 by the meshing.

  The guide portion 44 is provided on the inner surface of the bottom plate of the housing case 10 so as to extend in the vehicle width direction of the vehicle, and a plurality of rails 44a (a pair in FIGS. 1 and 3) can be moved along the rails 44a. A plurality of convex portions 44b that engage with each other. The moving amount detection unit 45 is electrically connected to the control unit 6 using a variable resistor, a Hall IC, a photo sensor, or the like as desired. The movement amount detection unit 45 outputs a movement amount signal corresponding to the movement amount of the base member 41 to the control unit 6.

  In the vehicle width direction moving means 4 configured in this way, the output of the drive unit 42 is transmitted to the base member 41 via the transmission unit 43, so that the base member 41 moves in the vehicle width direction W along the guide unit 44.

  The control unit 6 is composed of a microcomputer including a known CPU (Central Processing Unit) 61, ROM (Read Only Memory) 62, and RAM (A Read / Write Memory as needed) 63. The ROM 62 stores various data such as a movement control processing program for controlling the movement in the vehicle width direction of the vehicle width direction moving means 4 described above. The RAM 63 appropriately stores data necessary for the CPU 61 to execute various processes.

  In addition, when the display information of the display source 2 is projected onto the projection area E on the windshield 101, the windshield 101 is non-planar, so as shown in FIG. The virtual image S on the right side is visually recognized by a driver or the like with a distorted shape. Therefore, as shown in FIG. 4B, a plurality of pieces of correction information for correcting the distortion of the virtual image S are stored in advance in the ROM 62 or the like in correspondence with the display position of the virtual image S, that is, the moving position of the vehicle width direction moving means 4. I remember it. As an example of the correction information, various data structures such as having correction data for deforming the display information displayed on the display source 2 so that the virtual image 2 is linearly moved in the vehicle width direction are adopted. it can.

  Next, an example of the movement control process executed by the CPU 61 described above will be described below with reference to the flowchart shown in FIG. This process is premised on being activated in response to the display start of the display source 2 and forcibly terminated in response to a power-off, termination request, or the like.

  When the movement control processing program is executed by the CPU 61, it is determined in step S11 based on the operation signal from the operation unit 5 whether or not an operation corresponding to the operation in the vehicle width direction W has been performed. When it is determined that it is not operated (N in S11), the determination process is repeated to wait for an operation by the driver or the like.

L is projected onto the projection area E of the windshield 101. As a result, the driver visually recognizes the virtual image S of the display information and the foreground of the vehicle viewed through the windshield 101 from the eye point EP.

  When the driver's posture changes due to driving for a long time or the like and the visibility of the virtual image S by the driver is reduced, the driver moves the display position of the virtual image S in the vehicle width direction W in order to move to the operation unit 5. A predetermined operation is performed. Thereby, the HUD device 1 detects the selection position (display position) to be moved from the operation, and controls the vehicle width direction moving means 4 so that the vehicle width direction moving means within the storage case 10 up to the selected position. 4 is moved in the vehicle width direction W. As a result, the display light L from the display source 2 housed in the housing case 10 moves in an arbitrary direction in the vehicle width direction W of the projection area E, so the virtual image S moves in the vehicle width direction W. . Therefore, since the virtual image S is displayed at the display position suitable for the driver's posture, the visibility of the virtual image S by the driver can be improved.

  According to the HUD device 1 described above, even when the virtual image S adjusted in the vertical direction of the vehicle is difficult to visually recognize due to a change in the driver's posture, the virtual image S is moved in the vehicle width direction W.
