  In the present embodiment, the operation panel 11 is in a state in which the protrusion 18 in FIG. 3 is located at the uppermost portion of the guide groove 17, that is, in a normal use state in which the operation panel 11 is vertical as shown in FIG. Closed state. A state in which the projection 18 is positioned at the lowermost portion of the guide groove 17, that is, a state in which the operation panel 11 is horizontal as shown in FIG. A state in which the protrusion 18 is fixed at an arbitrary position between the uppermost part and the lowermost part of the guide groove 17, that is, a state in which the operation panel 11 is fixed at an arbitrary angle as shown in FIG. And

  In the navigation device 1 according to the present embodiment, screen display settings such as brightness and color tone are selected according to three states: a state in which the operation panel 11 is closed, a state in which the operation panel 11 is at an arbitrary angle, and a state in which the operation panel 11 is open. And display video can be set separately. For example, as shown in FIG. 7, the brightness is lowered when the operation panel 11 is closed (a), and the brightness is lowered when the operation panel 11 is opened (b) so that the display panel 14 illuminates the recording medium insertion slot or the like. Set high. In addition, as shown in FIG. 8, the contrast and darkness of the display panel are optimized so that the visibility of the display panel is optimal when the operation panel 11 is closed (a) and the operation panel 11 is at an arbitrary angle (b). In addition, it is possible to set the hue and the like.

  Regarding the control method of the navigation device 1 in the present embodiment, first, a case where the operation panel 11 is in an arbitrary angle state as shown in FIG. 2 will be described. While the operation panel 11 shown in FIG. 1 is closed, the MPU 30 continues to move the operation panel 11 until the operation panel 11 is opened as long as the user keeps pressing the operation panel open / close button 13 for a long time. At this time, the operation panel 11 shifts to the arbitrary angle state, and the MPU 30 changes the screen display setting of the display panel 14 to a set value when the operation panel 11 is in the arbitrary angle state. Here, in the present embodiment, there are three screen display settings associated with the three states of the operation panel 11 being closed, an arbitrary angle state, and the open state, and the angle of the operation panel 11 is arbitrary close to the closed state. In the angle state, the visibility of the display panel 14 is close to the closed state. Therefore, even if the MPU 30 shifts from the closed state to the arbitrary angle state, the screen of the display panel 14 remains until a predetermined angle is exceeded. The display setting is maintained in a state where the operation panel 11 is closed. When the MPU 30 changes the screen display setting in this way, for example, when the display on the display panel 14 becomes difficult to see due to reflection of light from the outside because the operation panel 11 is tilted, the display panel 14 is displayed. The visibility of the display panel 14 can be improved by increasing the luminance.

  Next, a state where the operation panel 11 is opened as shown in FIG. 4 will be described. When the operation panel 11 shown in FIG. 1 is closed or the operation panel 11 shown in FIG. 2 is at an arbitrary angle and the user presses the operation panel open / close button 13 for a short time, the MPU 30 is shown in FIG. The operation panel 11 is opened. At this time, when the operation panel 11 is opened, the screen display setting of the display panel 14 is changed to the value of the screen display setting with the operation panel 11 opened, or the display image is switched to make the entire display screen the brightest white. As a result, the display panel 14 brightly illuminates the recording medium insertion slot and the like. Here, due to the nature of the liquid crystal panel 27, if the entire display screen is the brightest white, the display screen will be brightest, but it can be changed to a color set by the user such as orange or blue. Even if the MPU 30 does not have illumination for the insertion slot that illuminates the MD insertion slot 22, the MD ejection button 23, the disk insertion slot 24, the disk ejection button 25, etc. by changing the setting of the screen display in this way, for example, By increasing the brightness, the display on the display panel 14 becomes brighter, and the insertion slot and the discharge button are lit brightly so that the user can easily recognize them.

  In the present embodiment, when the operation panel 11 is in an arbitrary angle state, the screen display setting in the arbitrary angle state is maintained when the angle equivalent to the state in which the operation panel 11 is opened is maintained. When the user presses the operation panel open / close button 13 for a short time to insert or eject the recording medium, the screen display setting is made with the operation panel 11 opened, and the display panel 14 brightens the recording medium insertion slot and the ejection button. Illuminated.

  Hereinafter, a modification in the case where the MPU 30 changes the display image in a state where the operation panel 11 is opened will be described.

  FIG. 9 is a perspective view showing an external configuration of a navigation device according to a modification of the present embodiment.

  The navigation apparatus according to the modification of the present embodiment has a CD drive and a DVD drive, and an upper stage includes a CD insertion slot 53 and a CD ejection button 54, and a lower stage includes a DVD insertion slot 51 and a DVD ejection button 52. It has become. When the user performs a CD or DVD insertion or ejection operation in a state where the operation panel 11 is closed or in an arbitrary angle state, if the operation panel open / close button 13 is pressed for a short time, the operation panel 11 is opened. At this time, the display image on the display panel 14 is changed to the image shown in FIG. It is possible to display various recording medium information on this display image. With respect to the CD drive and the DVD drive, whether each CD or DVD is inserted in each recording medium insertion slot is determined by each recording medium reader. The types of recording media that can be used, the types of recording media that cannot be used by the respective recording medium readers, and the types of storage media that are currently inserted are displayed.

  FIG. 10 will be described in detail. From the left side of the display panel 14, the navigation device has a CD drive in the upper row and a DVD drive in the lower row. Currently, a recording medium is inserted in the upper CD drive, and a recording medium is inserted in the lower DVD drive. You can see that it is not. The right side of the display panel 14 displays recording media that can be used for CD and DVD drives, and recording media that cannot be used, and the recording media information display allows recording media that can be used for the upper CD drive. CD-DA is inserted and nothing is in the lower DVD drive, so it can be seen that the type of the recording medium is not selected.

  Thus, the recording medium information can be displayed in a concise manner, and the convenience of insertion and ejection of the recording medium by the user can be enhanced.

  As mentioned above, although this invention was demonstrated based on one Embodiment, this invention is not limited to this. For example, in the present embodiment, the screen display setting is changed in each of the three states of the operation panel 11 being closed, the operation panel 11 being in an arbitrary angle state, and the operation panel 11 being in an open state. In, the screen display setting may be changed according to the angle of the operation panel 11 so that the visibility of the display panel 14 is optimized, instead of the single screen display setting. For example, the screen display setting may be changed every time the operation panel 11 is tilted 30 degrees.
