BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an on-vehicle equipment device, and more particularly to an on-vehicle equipment device having an image display section (hereinafter, referred to as a display device), in which the image is displayed only by pushing a button without using a motor. The present invention relates to a display device capable of opening and closing a display unit and the like.

[0002]

2. Description of the Related Art In recent years, particularly in a vehicle such as a passenger car, a display device as a vehicle interior information terminal for improving habitability and operability, that is, a display device having a so-called image display section (vehicle equipment device) There are some equipped with. By providing an image display unit, this display device can display not only a television screen but also various information such as the current position and congestion information using a navigation system. Therefore, it is desirable that such a display device body is embedded on the console box or dashboard on the front of the driver's seat or in the dashboard so as to improve the visibility of the driver's vehicle.

However, since various devices such as car audio devices such as radios and stereos and ventilator grills for air conditioners are generally arranged in these parts, the above-mentioned in-vehicle device device is installed. When the LCD monitor as an image display unit is attached to the
It is difficult to secure space.

Therefore, as described above, for example, when a liquid crystal monitor is attached to and mounted on an in-vehicle device, among those having a space on the console box on the front of the driver's seat or on the dashboard, or in the dashboard, etc. ,
At least, the space such as the console box is fried in consideration of the space that does not interfere with the functions of other devices and equipment, has good appearance, and can be easily mounted. This space is, for example, 2DIN (1
The size is 80 W × 100 H × 160 D), and a car audio device such as a stereo is mainly mounted in many cases. Therefore, in order to cope with this, each manufacturer manufactures car audio devices such as stereos in the above size. However, as described above, a car audio device is generally mounted in the space of the console box in many cases, and mounting a liquid crystal monitor poses a problem of hindering the operation of the car audio device. This is generally used as AM / FM for this car audio device.
Since it consists of a tuner, C / D player, power amplifier, cassette deck, and other devices, when installing the LCD monitor as described above, the AM
The operation unit such as the / FM tuner and the power amplifier can solve this problem by providing these operation units on the liquid crystal monitor, but the device such as the C / D player and the cassette deck has a problem in operation. Will be.

However, as a recent tendency, the above C /
By using the D player as a C / D autochanger device as is well known, it can be housed in a space such as a trunk room or a luggage room of a vehicle. This C / D autochanger accommodates a plurality of CDs, and a disc change is performed by an operation section separate from this apparatus to reproduce a digital sound. Therefore, since the operation unit is provided separately, the problem of space can be solved by providing this operation unit on the liquid crystal monitor.

On the other hand, a device such as a cassette deck is difficult to move to another place because of its structure, and it is indispensable because it is still the mainstream of car audio devices even after the spread of C / D players. It is a device. In addition, for example, when a liquid crystal monitor is attached to the cassette deck device, the cassette deck device has a cassette inlet / outlet for inserting / removing the cassette tape and a device for reproducing the cassette tape in space. A minimum space of 0.5 DIN is required, and the remaining space of 1.5 DIN constitutes the liquid crystal monitor. However, with this size, the screen size naturally becomes small, which causes inconvenience as a monitor.

Therefore, when the liquid crystal monitor is attached to the cassette deck device, the liquid crystal monitor can be attached without changing the size of the liquid crystal monitor, and in order to use the cassette deck device, the liquid crystal monitor must be moved to use the cassette. It is necessary to secure a space such as a cassette tape entrance / exit. Further, as a conventional technique, there has been proposed one in which the movement of the liquid crystal monitor is rotated by a driving means such as a motor, but naturally, a space for the motor or the like is indispensable and the price becomes expensive. There is a problem that ends up.

[0008]

As described above, in the conventional display device, when the monitor is attached to a device such as a cassette deck, the monitor is rotated to secure a space such as a cassette tape entrance and exit. There is a need to.
Therefore, when a driving means such as a motor is used as the rotating means, the number of parts constituting the rotating means also increases,
It is difficult to install because it is in a limited space. Further, there is a problem that the manufacturing process becomes complicated and the cost becomes expensive.

Therefore, the present invention has been made in view of the above problems, and the monitor can be rotated and stored in a storage case without using a drive means such as a motor for rotating the monitor, and an apparatus such as a cassette deck can be used. An object of the present invention is to provide a display device that can be used in combination with a monitor.

Next, the operation of the display device having such a configuration will be described in detail with reference to FIGS. 2 and 3
As shown in FIG. 5, the display device 11 shows a state in which the liquid crystal monitor 14 is stored in the storage case 12. In this state, the liquid crystal monitor 14 is also in a viewable state, and the display portion 14a of the monitor 14 faces the front side and the front side of the device 11.

Therefore, from the housed state of the liquid crystal monitor 14,
The operation of pulling out the liquid crystal monitor 14 to the front of the device 11 in order to use the accommodated cassette deck will be described.

In FIG. 3, first, in the state of the illustrated example, the open button 15 is pushed in the direction F (the arrow direction in FIG. 3). Therefore, the second slider 18 connected to the open button 15 slides at a predetermined position in the arrow direction indicated by G, that is, in the horizontal direction in conjunction with the force pressed by the open button 15. The sliding of the second slider 18 pushes up the sliding pin 19d fitted in the elongated hole 18C of the slider 18 while sliding the sliding pin 19d in the upward direction of the elongated hole 18c.

As a result, the third slider 19 fixedly attached to the sliding pin 19d slides at a predetermined position in the arrow direction indicated by H, that is, in the upward direction. As a result, the locking claw portion 19a formed to extend on the third slider 19 moves in the upward direction (the arrow direction indicated by H) together with the third slider 19. Therefore, the locking member 13a of the tray 13 that has been locked by the locking claw portion 19a is released from the locked state by the upward movement of the locking claw portion 19a.

As described above, since the locking claw portion 19a is disengaged from the locking member 13a, the tray 13 fixing the locking portion 13d is moved by the spring 21 urging in the forward direction. The tray 13 is slid to the predetermined position in the direction of the arrow I. The sliding of the tray 13 is performed until the supporting member 13c provided on the tray 13 is joined to the rotating arm 20, and the slide 13 is finished at the same time. Since the rotating arm 20 is joined to the first slider, the rotation of the rotating arm 20 can be locked to support the tray 13.

On the other hand, in the liquid crystal monitor 14 rotatably attached to the support member 13b at the same time as the tray 13 slides, the sliding pins 14b attached to both side surfaces of the monitor 14 are downwardly directed to the slot 12c. The movement of the support member 13b causes the support member 13b to rotate about the axis thereof. That is, the liquid crystal monitor 14 is pulled down and the upper part is lowered to fall it down. Thereby, the storage case 12
A space for the cassette inlet / outlet port 12a such as a cassette deck device provided in the upper part of the front surface of the cassette can be obtained, and the cassette tape can be taken in and out.

Next, the operation of housing the liquid crystal monitor 14 in the front of the housing case 12 will be described with reference to FIGS. 4 and 5. As shown in FIGS. 4 and 5, the display device 11 shows a state in which the liquid crystal monitor 14 is pulled out to the front of the storage case 12. Further, in this state, for example, a cassette deck device (not shown) housed in the device 11 can be used, and a usable space for the cassette inlet / outlet 12 for loading / unloading a cassette tape or the like is secured. .

In FIG. 5, first, in the state of the illustrated example, the close button 16 is pushed in the direction F (the arrow direction in FIG. 5). Therefore, the first slider 17 connected to the close button 16 slides in the horizontal direction by the distance indicated by B in conjunction with the force pressed by the close button 16. Therefore, when the first slider 17 slides, the sliding pin provided on the rotary arm 20 joined to the base end of the slider 17 is pushed up while sliding. That is, by sliding the first slider 17 in the horizontal direction by the distance indicated by B, the pivot arm 20 pivots about the point A as indicated by D. As shown in the illustrated example, the pivoting arm 20 that pivots has a point A as an axis, so that the base end portion of the arm 20 is, as a matter of course, the tray B rather than the stroke B pushed by the first slider 17. The stroke C for pressing 13 is larger. Therefore, the supporting rod 20a provided at the base end of the rotating arm 20 pushes up the supporting member 13c of the tray 13 joined to the supporting rod 20a in conjunction with the rotating operation, that is, the stroke of the tray 13 shown in C. Slide only minutes.

Thereafter, as the tray 13 slides, the locking member 13A provided at a predetermined position on the rear portion of the tray 13 is locked by the locking claw portion 19a of the third slider 19. . It should be noted that, after the rotating arm 20 rotates to move the tray 13, the rotating arm 20 naturally reverses again around the point A as an axis and is joined to the first slider 16 to return to the original state. ing.

On the other hand, the liquid crystal monitor 14, which is rotatably held by the first support member 13b on both sides of the front surface of the tray 13, rotates the point a of the support member 13b as the tray 13 slides. While rotating, the sliding pins 14b attached to both side surfaces of the monitor 14 move upward in the elongated hole 12c. That is, the liquid crystal monitor 14 is in a state in which the lower part is rotated downward about the point a and the upper part is raised in the frontward direction. Thereby, the storage portion 12b provided on the front surface of the storage case 12
The liquid crystal monitor 14 can be housed inside. As a result, the liquid crystal monitor 14 can view the liquid crystal monitor 14 because the display unit 14a for displaying a screen on the front surface of the device 11 can be turned to the front.

As described above, in this embodiment, when the liquid crystal monitor 14 is attached to a device such as a cassette deck device, the liquid crystal monitor 14 can be used, and further, the cassette deck device or the like can be used. Since it is necessary to rotate the liquid crystal monitor 14 to secure a space for the cassette inlet / outlet port 12A in order to use the tray, a slidable tray 13 is provided on the bottom surface of the storage case 12, and the first support member 13b or the long support member 13b is provided. By rotating the monitor 14 using the hole 12c as the tray 13 slides, a space for the cassette inlet / outlet 12a can be secured and the monitor 14 can be stored in the front of the storage case 12. . Thereby, the liquid crystal monitor 14 and a device such as a cassette deck can be used together. Further, the display device 11 has an open / close button 1
Since it is configured to operate by pressing 5, 16 or the like, the rotation 14 of the liquid crystal monitor can be performed by manual force. Therefore, it is possible to rotate the liquid crystal monitor without using a driving unit such as a motor, and it is not necessary to use a driving unit such as a motor. Therefore, it is possible to reduce the number of parts and to facilitate the manufacturing process. It is possible to reduce the cost as well as the cost.

In this embodiment, the liquid crystal monitor 14 is mounted as a display device on a device such as a cassette deck, but the liquid crystal monitor 14 is mounted on a device different from the cassette deck device. It may be configured.

Further, in the present embodiment, the operation section of the liquid crystal monitor 14 and the apparatus such as the cassette deck may be constructed as a remote control type operation section operable by a remote control signal.

[0033]

As described above, according to the present invention, the liquid crystal monitor 14 can be moved while rotating without using any driving means such as a motor by simply pressing the open / close button, and is stored in the storage case 12. be able to. As a result, the number of parts constituting the device can be reduced, the manufacturing process can be facilitated, and the cost can be reduced.

Further, since the monitor can be viewed when the monitor is stored and a space for a cassette entrance / exit such as a cassette deck is secured when the monitor is pulled out, this cassette deck device can also be used. As a result, one display device can be used in combination with the two devices.
