Description of the Related Art A display body equipped with a liquid crystal display panel or the like is installed in the interior of an automobile so that terrestrial television broadcasts or satellite television broadcasts can be displayed on the screen or map information of a navigation system can be displayed. It is becoming common to Conventionally, as a structure for mounting this type of display body in the vehicle compartment, the display body is attached to the tip of a pillar-shaped bracket rising from the floor surface in the vehicle interior, or the area where the audio equipment of the console panel is embedded. There is used a display body that is housed in the vehicle and that is projected in a substantially horizontal posture from the housing portion into the vehicle compartment and is rotated so as to stand up after the projection.

[0003]

In the case of using the strut bracket, this strut bracket narrows the space in front of the passenger seat of the automobile, for example, which causes the space in the passenger compartment to be narrowed. The structure in which the display body is housed in the buried area of the audio device is superior to the structure using the support bracket without narrowing the living space in the vehicle interior when the display body is not used. However, the storage area of the audio device on the console panel in the automobile is limited, and normally only two devices each having a size of 1 din can be installed. If the display body is housed in one of the installation areas, the area in which the audio device can be installed is only one area having the size of one din. Therefore, it becomes impossible to install the cassette tape player and the disc player in combination, which narrows the selection of the usage form of the audio equipment.

The present invention solves the above-mentioned conventional problems, and provides a display device in which a housing for installing a display body can be used as an audio device or the like, and an installation space of the device can be effectively used. The purpose is to do.

[0005]

A display device according to the present invention is provided in a housing with an insertion opening into which a recording medium housed in a case is inserted, a holding portion for holding the case inserted through the insertion opening.

It has a display body installed outside the body.

This display device is used, for example, as a vehicle-mounted type, and the casing is installed in an area of, for example, one din of a console panel of an automobile. The recording medium is a compact disc or another disc or tape, or an IC card. One or more recording media are stored in the case. When the case is attached to the holding portion through the insertion opening, the recording medium drive mechanism performs the reproducing or recording operation on the recording medium with one or more recording mediums housed in the case, or one case from the case. The recording medium is taken out and the recording medium drive mechanism performs a reproducing or recording operation. The recording medium drive mechanism is a disk drive mechanism having a turntable or an optical head when the recording medium is a disc, a tape drive mechanism when the recording medium is a tape, and an IC card when the recording medium is an IC card or the like. It is an information reading mechanism (information reading means) for reading the information of.

The support has the same external shape and size as the case for housing the recording medium. This support may be a so-called dummy case without containing the recording medium inside, but when the recording medium is housed inside the supporting body and the supporting body is held by the holding portion, It is also possible that the recording medium can be driven.

Further, according to the present invention, there is provided an operating body provided with an operating member which is detachable from the housing and which operates a mechanism in the housing, and a support body mounted on the housing in place of the operating body. And a display connected to the support. This support is different from a display element such as a small liquid crystal panel provided on the operating body, and is provided with, for example, a color liquid crystal display panel having a large screen.

[0009]

In the above means, the recording medium drive mechanism is built in the housing, and when the case containing one or more recording media is inserted from the insertion port, the recording medium is inserted into the case. In the state where it is still inside, or the recording medium is pulled out from the case and driven by the recording medium drive mechanism,
Playback or recording of sound is performed. Instead of the case in which the recording medium is stored, when the support is inserted from the insertion port and the support is held by the holding portion, the support is movably connected to the support or integrally connected to the support. The display body is installed outside the housing. In the case of a vehicle, in which the support is held by a housing built in the console panel, the display is installed in front of the console panel and the screen of the liquid crystal display panel etc. provided on the display can be viewed. Like

The lead portion for supplying electric power to the display body and for supplying a video signal is a wire or a flexible cable, and extends from the display body to a predetermined portion of the support body. When the support body is mounted on the holding portion, the land portion or the connector portion of the terminal of the lead portion extending to the support body is a signal of a connector or an elastic contact terminal provided at any position in the housing. The circuit and the like in the housing are electrically connected to the display body by being in contact with and electrically connected to the supply means.

The support body for supporting the display body is a dummy case which does not include a recording medium therein and has the same shape and size as the case. In the case of this dummy case support, a circuit for driving the liquid crystal display panel of the display body, an IC for a navigation system or other information stored therein, and a television broadcast reception are provided inside the support body. A tuner etc. can be built in. Alternatively, if a recording medium such as a disc that is stored in the case is stored in a support body that supports the display body, the recording medium in the support body is moved to the recording medium drive mechanism with the display body installed. Can be driven by. The recording medium in this case may be, for example, one recording map information for navigation system or the like related to the display information on the display, a video disc for karaoke, or the like, and audio information unrelated to the video information. It may be recorded.

Further, in the above-mentioned means, in the case where the operating body can be detached from the housing, the supporting body to which the display body is connected is attached instead of the operating body. In the case of an on-vehicle audio device, the operating body can be removed to prevent the entire device from being stolen from inside the vehicle. By using the support body instead of the operating body and mounting the support body on the housing, the display body can be connected to the housing.

Each of the above means can be used as an audio device or the like when the display body is not used, and the support body can be attached to the housing only when the display body is used to view the image of the display body or the like. Like Therefore, when the installation space of the housing is limited, such as for in-vehicle use, the housing can be used for both the acoustic device and the display device,
Effective use of space will be achieved.
