In this case, the shutter includes a pair of shutter members vertically overlapped, and is slidably engaged with a top shutter member and a bottom shutter member. Further, the shutter movement mechanism includes a shutter arm which rotatively moves with power from the drive motor; an articulated arm that, being connected to the flapper arm and coupled to the top flapper member, forms a hinge mechanism; and a guide plate that stands upright on one side of the reflection plate and in which a first guide groove configured to guide the movement of the top side flap member and a second guide groove configured to move the bottom side flap member lead, educated are. The pair of shutter members then move between the closed position and the open position while an overlapping width is shifted with each other by moving the articulated arm in response to a rotational movement of the shutter arm.

Here, in the present invention, preferably, by reducing an overlap width with each other along an opening and closing direction in the closed position, the pair of shutter members are arranged widely in parallel and the pair of shutter members are narrowly parallel to each other by increasing the overlapping width along the opening and closing direction in the opening position arranged and also pulled in a vertically inclined form of the opening.

Further, in the present invention, the display device for a vehicle preferably includes a control unit configured to control movement operations of the shutter and the reflection plate, the control unit moving the reflection plate from the stored position to the developing position after the shutter is stored in the open position is.

Advantageous Effects of the Invention

In accordance with the present invention, a flapper includes a pair of flapper elements that overlap one another. Thus, in a shutter, a wide width can be selected to cover a large opening by changing an overlapping width of the shutter members, and a narrow width can be selected when an opening for supporting the shutter is opened. Thus, the opening on an upper surface of a bearing housing for inserting and removing a reflection door by the shutter can be securely closed with a compact configuration.

7 Figure 3 is a block diagram illustrating a control system of the HUD device 1 in accordance with the embodiment. A control unit 100 has a function of controlling the HUD device 1 on, z. As a microprocessor unit (MPU) or the like is used. The control unit 100 contains a central processing unit (CPU), ROM, RAM and the like. The CPU is a control method for executing each process, each control and the like in accordance with a predetermined program. The ROM is the read only memory that stores a program or the like for the CPU. The RAM is a readable and writable memory which stores each type of data and has an area necessary for a processing operation of the CPU.

In the control unit 100 Be information about the surrounding brightness, which is caused by a light sensor 103 is detected, and predetermined information via an input / output interface (I / O) connected to the CAN 104 entered.

The control unit 100 controls via an LCD driver 21 a liquid crystal display (LCD) 22 that is part of the lighting device 2 forms. Further, the control unit 100 with a motor driver to drive the combiner 101 by outputting a control signal to the motor driver for driving the combiner 101 the drive motor 32 turning on and a move operation of the combiner 3 controls. In addition, the control unit 100 with a motor driver for controlling the shutter 102 by outputting an operation signal to the motor driver for driving the shutter 102 the drive motor 81 turning and a moving operation of the shutter 7 controls.

The following is a moving operation of the shutter 7 in the HUD device 1 described in accordance with the embodiment. 8th Fig. 10 is a flowchart illustrating a procedure of an opening operation of a shutter. The opening operation of the shutter 7 is an operation to the flap 7 , which is positioned in a closed position, to move to an opening position and is before a developing operation to the combiner 3 from a stored position to move to a development position executed. As in 9 is a pair of shutter members 71 and 72 arranged in parallel along an opening and closing direction.

In the case of performing the development operation of the combiner 3 must be an operation signal to control the shutter 102 be output to the motor driver, so that the process in step 10 (S10) is determined positively and to step 11 (S11) passes. On the other hand, no operation signal for driving the shutter needs 102 to be issued to the motor driver so that the process in step 10 is determined negatively and the process in step 10 is executed again if the development operation of the combiner 3 not executed.

In step 11 gives the control unit 100 an operation signal for driving the shutter 102 to the motor driver. In this way, the motor driver will supply a predetermined current to drive the shutter 102 to the drive motor 81 is output and moves the drive motor 81 rotation.

When the drive motor 81 rotates driving, the drive gear rotates 83 synchronously, so that is the first multi-stage gear 84 and the second multi-stage gear 85 and the driven gear 86 and the arm attachment section 87 rotate. In accordance with the rotation of the arm attachment portion 87 the shutter flap arm rotates 88 around the arm attachment section 87 , In this case, the shutter arm rotates 88 from back to front and moves the articulated arm 90 along with the rotation also from back to front. In this case, the articulated arm 90 moved by passing through the first guide grooves 92a and 92b by the presence of the connecting sections 90a and 90b to be led.

When the articulated arm 90 moves, moves the top flap member 71 together with the articulated arm 90 also from back to front. When the top flap element 71 in this case, with respect to the bottom flap member 72 slides, takes an overlap width of a pair of shutter members 71 and 72 to and becomes maximum (see 10 ). When the overlap width becomes maximum, a pair of the shutter members are lowered 71 and 72 in the bearing housing 6 while they are in sync with each other (see 11 ). In this way, a pair of the shutter members 71 and 72 out of the opening 62a pulled in a vertically inclined shape and positioned in an open position.

Again, based on 8th determines the control unit 100 in step 12 whether a flapper operation is shot down, more specifically, whether the flapper 7 moved to the opening position. If the process in step 12 is positively determined, more specifically, if the shutter operation is completed, the process goes to step 13 via (S13). On the other hand, the process comes to a step 11 back if the process in step 12 is determined negatively, more specifically, if the shutter operation is not completed.

In step 13 gives the control unit 100 a stop signal to the motor driver for driving the shutter 102 out. Thus, the current supplied by the motor driver for driving the flap 102 to the drive motor 81 interrupted and stops the drive motor 81 at.

In step 14 (S14) gives the control unit 100 an operation signal to the motor driver for driving the combiner 101 out. Thus, the motor driver will provide a predetermined current to drive the combiner 101 to the drive motor 32 fed and drives the drive motor 32 turning on.

When the drive motor 32 rotationally drives power of the drive motor 32 transferred to the combiner movement mechanism and moves the combiner 3 upwards (see 12 ). When the combiner 3 then reaches an upper limit position determined by the combiner movement mechanism, the combiner reaches 3 a development position (see 13 ).

In step 15 (S15) determines the control unit 100 whether a combiner operation is complete, more specifically, whether the combiner 3 moved to the development position. If the process in step 15 is positively determined, more precisely, if the combiner operation is completed, the process goes to step 16 via (S16). On the other hand, the process comes to a step 14 back if the process in step 15 is determined negative, more precisely, if the combiner operation has not been completed.

In step 16 gives the control unit 100 a stop signal to the motor driver for driving the combiner 101 out. In this way, one of the motor driver for driving the combiner 101 to the drive motor 32 supplied power is interrupted and stops the drive motor 32 at. Through such a series of operations becomes an opening operation of the shutter 7 including a development operation of the combiner 3 completed.

Further, a closing operation of the shutter 7 in accordance with a reverse procedure to the above-described procedure by reversely operating the drive motor 81 executed. The closing operation of the shutter 7 Here is an operation to the shutter positioned in an open position 7 to move to a closed position, and is executed after a storage operation to the combiner 3 move from a development position to a stored position.

In addition, a user occasionally switches an ignition switch in the presence of the combiner 3 in the development position. In this case, the control unit performs 100 to the next start time after the combiner 3 has been moved to the stored position, a closing operation of the shutter 7 out. 14 is a flowchart showing a closing operation of the shutter 7 when power is supplied represents.

First, the process is in step 20 positively determined and he goes to step 21 via (S21) when an ignition switch (IGN) is turned on. On the other hand, the process is not going to move 21 over and he returns to step 20 back if the IGN is not turned on.

In step 21 gives the control unit 100 an operation signal to the motor driver for driving the combiner 101 out. Thus, the motor driver will provide a predetermined current to drive the combiner 101 to the drive motor 32 fed and drives the drive motor 32 turning on.

In step 22 (S22) determines the control unit 100 whether a combiner operation is complete, more specifically, whether the combiner 3 moved to the stored position. If the process in step 22 is positively determined, more precisely, if the combiner operation is completed, the process goes to step 23 via (S23). On the other hand, the process comes to a step 22 back if the process in step 22 is determined negative, more precisely, if the combiner operation has not been completed.

In step 23 gives the control unit 100 a stop signal to the motor driver for driving the combiner 101 out. In this way, one of the motor driver for driving the combiner 101 to the drive motor 32 supplied power is interrupted and stops the drive motor 32 at.

In step 24 (S24) gives the control unit 100 an operation signal to the motor driver for driving the shutter 102 out. In this way, the motor driver will supply a predetermined current to drive the shutter 102 to the drive motor 81 fed and drives the drive motor 81 turning on.

In step 25 (S25) determines the control unit 100 whether a flapper operation is complete, more specifically, whether the flapper 7 moved to a closed position. If the process in step 25 is positively determined, more specifically, if the shutter operation is completed, the process goes to step 26 via (S26). On the other hand, the process comes to a step 24 back if the process in step 25 is determined negatively, more precisely, if the shutter operation has not been completed.

In step 26 gives the control unit 100 a stop signal for the motor driver for driving the shutter 102 out. Thus, one of the motor driver becomes to drive the shutter 102 to the drive motor 81 supplied power interrupted and stops the drive motor 81 at. Over a series of operations becomes a closing operation of the shutter 7 including a storage operation of the combiner 3 completed.

In the embodiment as described above, the HUD device includes 1 the bearing housing 6 , the combiner 3 , the flap 7 , the shutter movement mechanism 82 and the drive motor 81 , The bearing housing 6 Contains the opening on an upper surface thereof 62a , The combiner 3 is movably disposed between a stored position and a development position and reflects the illumination device 2 emitted indicator light L1. The flap 7 is at the opening 62a the storage device 6 arranged. The shutter movement mechanism 82 moves the shutter 7 between a closed position and an open position. The drive motor 81 Performs by transferring power to the shutter movement mechanism 82 a movement operation of the shutter 7 out. In this case, the shutter contains 7 a pair of shutter members 71 and 72 that are vertically overlapped. The top flap element 71 and the bottom flap member 72 are slidably engaged. Further, the shutter flap moving mechanism includes 82 the shutter flap arm 88 , the articulated arm 90 and the auxiliary plate 92 , The shutter arm 88 rotates with power from the drive motor 81 , The articulated arm 90 forms a hinge mechanism by connecting with the flapper arm 88 is connected and with the top hinge element 71 is coupled. In the auxiliary plate 92 are the first guide grooves 92a and 92b and the second guide groove 92c educated. The first guide grooves 92a and 92b stand on one side of the combiner 3 upright and guide the movement of the top flap element 71 , The second guide groove 92c performs the movement of the bottom flap member 72 , The articulated arm 90 moves in the shutter movement mechanism 82 in response to the rotational movement of the shutter flap arm 88 and a pair of the shutter members 71 and 72 Moves by moving an overlap width between each other between the closed position and the open position.

In accordance with the embodiment described above, the shutter includes 7 a pair of shutter members 71 and 72 that are overlapped with each other. Thus, in the flap 7 By changing an overlap width with each other, a wide width can be selected around the large opening 62a to cover, and a narrow width can be selected when the shutter 7 by opening the opening 62a is stored. Thus, the opening 62a on an upper surface of the bearing housing 6 for taking in and taking out the combiner 3 through the flap 7 be securely closed with a compact configuration during a bearing and a moving operation.

Further, in the embodiment, by reducing an overlapping width with each other in a closing position, a pair of the shutter members are 71 and 72 arranged in parallel along an opening and closing direction. On the other hand, a pair of the shutter members 71 and 72 along the opening and closing direction, by increasing the overlapping width with each other narrowly parallel to each other in an opening position, and also it becomes out of the opening in a vertically inclined shape 62a moved in.
