Front panel operating apparatus and method

A front panel operating apparatus of a car audio, comprising:

• a main chassis configured to receive an audio device, wherein the audio device is configured to receive and eject an information medium through an entrance;
• a front panel coupled to the main chassis having a display part exposed in a front side, wherein the front panel selectively covers the entrance;
• a protruded section protruded from an upper portion of at least one of the main chassis and the front panel toward the other of the main chassis and the front panel;
• a guide configured to engage the protruded section, wherein the guide is coupled to the other of the main chassis and the front panel, wherein the guide extends a prescribed distance in substantially a first direction;
• a supporting panel pivotably coupled to a lower portion of the front panel, wherein the supporting panel is configured to reciprocally move in substantially a second direction that is perpendicular to the first direction;
• a supporting panel diving section configured to move the supporting panel in the second direction to controllably adjust an inclination angle of the front panel with respect to the main chassis among a plurality of values from a closed position covering the entrance;
• and
• a gyro device coupled to the main chassis such that an installation angle thereof is controllable;
• a communication hole formed in the main chassis and serving as a rotational center for controlling the installation angle of the gyro device;
• a control slot arranged concentrically with the center of the communication hole and formed in a curvature corresponding to a rotational trace of one side of the gyro device;
• a hook protrudedly formed on a lower side of a gyro housing constituting an outer shell of the gyro device and rotatably mounted on an inner circumference of the communication hole;
• and
• a coupling device coupled to a selectable position of the control slot and the gyro housing for fixing the installation angle of the gyro device.

A front panel operating apparatus of a car audio, comprising:

• a main chassis configured to receive an audio device, wherein the audio device is configured to receive and elect an information medium through an entrance;
• a front panel coupled to the main chassis having a display part exposed in a front side, wherein the front panel selectively covers the entrance;
• a protruded section protruded from an upper portion of at least one of the main chassis and the front panel toward the other of the main chassis and the front panel;
• a guide configured to engage the protruded section, wherein the guide is coupled to the other of the main chassis and the front panel, wherein the guide extends a prescribed distance in substantially a first direction;
• a supporting panel pivotably coupled to a lower portion of the front panel, wherein the supporting panel is configured to reciprocally move in substantially a second direction that is perpendicular to the first direction;
• a supporting panel driving section configured to move the supporting panel in the second direction to controllably adjust an inclination angle of the front panel with respect to the main chassis among a plurality of values from a closed position covering the entrance;
• and
• a gyro device attached on an inner surface or an outer surface of the main chassis to ascertain a moving direction of a vehicle, the gyro device being used in a navigation system of the vehicle.
