Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an on-vehicle electronic device such as an audio device, a telephone device, a navigation system, or a facsimile device, and more particularly to an on-vehicle electronic device having an operation section and a display section.

[0002]

2. Description of the Related Art FIG. 7 is a partial front view showing the structure of an operating portion of a general vehicle-mounted audio equipment. In an on-vehicle audio device, for example, a 1-din (DIN) size housing is embedded in a storage portion of an instrument panel in a vehicle compartment, and is fixed to the front surface of the housing.
Appears on the front of the instrument panel. On the front panel 1, a push button or rotary knob type operation member 2 is arranged. Further, the front panel 1 is provided with a display unit 3 such as a liquid crystal display panel. The display unit 3 displays, for example, a song number or the like when a disc is driven or an equalizer display, and the tuner is operating. Occasionally, a tuning display is displayed.

[0003]

In the conventional on-vehicle audio equipment shown in FIG. 7, the area of the front panel 1 is limited to a so-called 1-din (DIN) size, and a predetermined number of operating members 2 are provided. Therefore, the area of the display unit 3 is limited, and thus the information that can be displayed is also limited. On the contrary, when the area of the display unit 3 is widened, the arrangement area of the operation member 2 becomes narrow, and the number of the operation members 2 that can be arranged is limited.

In the future electronic devices for vehicles, FM and AM
Radio reception and dual use as both compact disc player and mini disc (MD) playback device,
Further, it is expected that multi-use such as dual use as a navigation system and addition of functions as a telephone device and functions such as transmission and reception of various information will progress. In such a case, in the case shown in FIG. 7, the area of the display unit 3 is too small, and it is difficult to display various kinds of operation information and operation information in an easily viewable state. In addition, a limited number of operating members 2
Therefore, it is difficult to input all the functions, and a single operation member 2 is used to perform a multi-function input operation, resulting in a confusing operation. Further, in a case where a recording medium such as a disk or a tape cassette is inserted into the housing, the front panel 1 has openings for inserting these recording media.
The area will be limited.

The present invention is to solve the above-mentioned conventional problems, and in a case having a housing of a limited size, a sufficiently wide arrangement space for operating members is ensured, and
It is an object of the present invention to provide an in-vehicle electronic device that can be provided with a sufficiently wide display screen.

It is another object of the present invention to widen the space for disposing the display member, secure a wide display screen, and make it possible to insert a recording medium such as a disk or a tape cassette.

[0007]

According to the present invention, a housing provided on a vehicle body is provided with a display body having a display screen and an operating body on which an operating member is arranged. One is movable from a position housed inside the housing to a position projecting to the front of the housing, and the other is movable further forward from the front of the housing. The display device is characterized in that the display device is installed in a posture in which the display can be seen and operated in front of the housing.

According to the present invention, since one of the display body and the operating body projects from the position housed in the housing, the display body and the operating body can be operated even if the front surface area of the housing is limited. When is located in front of the housing, a sufficiently large space for disposing the operation member and a sufficiently wide display screen can be secured.

For example, the display body is accommodated in a horizontal posture in the casing, and when it protrudes to the front of the casing, it is rotated upward to make the display visible, and the operating body is the display body. Is at a position that substantially closes the front surface of the housing when the housing is housed in the housing, and when the operating body projects from the housing, is in a position that does not hinder the protruding movement of the display body and is in an operable posture. Thus, it moves to the front of the housing.

In this case, the operating body is installed at a position that closes the front surface of the housing with the operating surface facing inward of the housing.
It will rotate from that position to the front of the housing. Or
When the operating body is in a position to close the front of the housing, the operating surface is directed to the front surface, and the operating member can be operated as it is,
It may be a structure in which the operating body moves diagonally forward when the display body projects.

Alternatively, the display body is installed with the screen facing forward at a position where it blocks the front surface of the housing, and at this time, the operating member is housed inside the housing, and the display body is slanted on the housing. It may be a structure in which the operating body moves substantially parallel to the upper direction and the like and the operating body projects from the inside of the housing to an operable posture in front of the housing.

Further, when the display body and the operating body are located in front of the housing, it is preferable that the recording medium can be loaded into the housing through the gap between the display body and the operating body.

When the display body and the operating body are vertically arranged in front of the housing, a recording medium insertion opening appears from a gap between the two and the recording medium can be inserted into the housing through the insertion opening. With such a structure, even in the case of an electronic device having a small front surface, a space for arranging the operation members can be secured, a wide display screen can be realized, and a recording medium can be further inserted.
It becomes possible to exhibit various functions, and even if the electronic device is made to have multiple functions, it has sufficient display capability and enables operation input corresponding to the multi-function.
