2. Description of the Related Art Recently, a display member equipped with a liquid crystal panel or the like used as a TV receiver or a display screen of a navigation system has been installed inside a car. Generally, a display member having a liquid crystal panel is attached to the upper ends of dedicated support legs that stand up from the floor surface of an automobile or the like.
A display member storage type display device as shown in FIG. 13 has also been proposed. The structure is such that a housing 1 embedded in a console panel P in the interior of an automobile is provided with a drive bracket 2 that moves in the A1-A2 direction, and the drive bracket 2 has a monitor screen 3a such as a liquid crystal panel. 3 is rotatably supported. Drive bracket 2 is A
When the display member 3 moves in two directions and moves to the rear end in the housing 1, the display member 3 assumes the horizontal posture shown in (a).
It is stored inside. When the drive bracket 2 moves in the A1 direction, the display member 3 protrudes toward the front of the housing 1, and the display member 3 rotates in the rising posture shown in (b) in accordance with the protruding operation, and the monitor screen 3a is displayed in the vehicle interior. Directed to.

[0003]

However, in the case where the display member is attached to the support leg rising from the floor or the like, the display member narrows the living space.
It cannot be a device having a large display screen, but is as small as a 5-inch screen. Further, in the display member storage type shown in FIG. 13, the display member 3 is housed in the housing 1 when not in use, and the display member 3 stands up at a position close to the console panel P when in use. Does not narrow the living space so much.

However, in the case shown in FIG. 13, since the housing 1 is embedded in the console panel P, there is a limit in the internal volume, and therefore the display member 3 cannot be made too large. Further, since the display member 3 may hit the shift lever 4 or the like when protruding in the A1 direction in the horizontal posture, this also limits the enlargement of the display member 3. In either case, the screen of the display member used in the in-vehicle display device becomes small, and the information display area is limited. A screen such as a liquid crystal panel is generally horizontally long in which the width dimension in the X direction is larger than the width dimension in the Y direction in FIG. 13. For example, in the screen used as a navigation system, the current position of the vehicle is Since the arrow indicating the traveling direction and the like are often displayed so as to point upward in the Y direction, the map information in the traveling direction, that is, the Y direction indicated by the arrow or the like becomes short on the horizontally long screen, and the destination direction is identified. Can be difficult.

The present invention solves the above-mentioned conventional problems, and provides a display device capable of accommodating a living space without narrowing it when not in use and substantially increasing the information display area when in use. The purpose is to do.

[0006]

A display device according to the present invention includes a first display member that can move between a position housed in a housing and a position installed outside the housing, and a first display. A second display member that is arranged with the first display member in a state where the member is installed outside the housing is provided, and the first and second display members are provided with each other in a state where both the display members are arranged. It is characterized in that adjacent screens are provided.

In this case, it is possible to adopt a structure in which the second display member is installed on the front surface of the housing while the first display member is housed in the housing.

Further, the display member of the present invention has a housing having a front surface on which a recording medium insertion opening or an operating portion is formed, a position installed on the front surface of the housing, and a position where the insertion opening or the operating portion appears. A first display member that can move between the first display member and a second display member that is arranged side by side with the first display member, and both the display members are arranged on the first and second display members. It is characterized in that screens adjacent to each other in a state are provided.

In the above, the second display member may be detachable from the first display member,

Alternatively, the second display member and the first display member may be connected so as to be folded so as to overlap each other.

[0011]

In the present invention, since the display member is housed inside the housing, the living space is not narrowed by the display member which is not used. In addition, since the screens of the first and second display members are located adjacent to each other during use, the information display area is substantially increased. It is possible to display different information on each screen, and when using it as a navigation system,
Both screens can be arranged vertically. In this case, if the traveling direction of the automobile is displayed by an upward arrow or the like, the map information in the traveling direction can be displayed wider than before.

The second display member can be housed in the housing together with the first display member. However, when the first display member is housed in the housing, the second display member can be stored in the housing. If installed in front of the housing, information can be displayed only on the screen of the second display member.

Further, according to the present invention, when the recording medium insertion port and the display member are provided on the front surface of the housing, the first display member can be normally housed in a position covering the front surface of the housing. . When the first display member is moved, the insertion opening and the display member appear, and the recording medium can be inserted into the housing and various operations can be performed. Also in this case, when the first display member is separated from the front surface of the housing, the second display member is connected and the screens of both display members are adjacent to each other, so that the information display area can be substantially increased.

At this time, the second display member may be detachable from the first display member, or both the display members may be folded with the first and second display members folded. You may store in the position which covers the said insertion opening and a display member.
