Description

  The present invention relates to an in-vehicle device.

As a conventional navigation device, there is one constituted by a main device and a front panel supported to be tiltable on the front surface of the main device. The front panel is provided with a display unit, an operation unit, and the like.
In such a navigation device, an insertion / extraction port for inserting / extracting a storage medium such as a CD (Compact Disk) is provided on the front side of the main device. Such an insertion / extraction opening is usually provided in the upper part of the main device so as to be exposed by tilting the front panel.
In such a navigation device, when the interior of the vehicle is dark, it is difficult to understand the position of the insertion / extraction port, and therefore it may be difficult to insert and eject the storage medium.
Therefore, in the conventional navigation device, the display unit of the front panel is tilted, and the insertion / extraction port is illuminated by the display light emitted from the display unit.

On the other hand, Patent Documents 1 to 4 disclose a configuration in which a navigation unit can be detached from an in-vehicle device mounted on a vehicle. By removing the navigation unit from the in-vehicle device, the navigation unit can be used alone as a portable navigation.
In Patent Document 5, it is possible to remove the navigation device from the vehicle and use the navigation device even during walking. Further, it is disclosed that the car navigation mode is set when the vehicle is mounted, and the man navigation mode is executed when the vehicle is detached from the vehicle.

However, as described above, in the case of an in-vehicle device that detachably holds the navigation unit, the insertion / extraction port cannot be illuminated when the navigation unit is removed from the in-vehicle device.
Therefore, in order to illuminate the insertion / extraction port, it is also possible to provide illumination means on the main device side of the in-vehicle device.
However, when the lighting device is provided in the main device in this manner, the main device has a built-in reproducing device for reproducing the normal storage medium. Therefore, the control board for controlling the entire main device is the main device. Can only be placed at the bottom of Therefore, it is necessary to mount the light source of the illumination means on the control board. When the illumination unit is mounted on the control board, it is necessary to guide the illumination light of the light source to the insertion / extraction port, and thus it is necessary to extend the light guide member from the light source to the insertion / extraction port. Therefore, a large light guide member is required.
In addition, since the position from the light source to the insertion / extraction port is far, even if the illumination light is guided by the light guide member, there is a possibility that sufficient irradiation may not be performed on the insertion / extraction port when the amount of light is small. It is necessary to use a strong light source.
However, when a large light guide member or a light source with a strong light amount is used, the components built into the main device may be increased in size, and as a result, the main device itself may be increased in size.

And a front panel disposed so as to be tiltable so as to expose and shield the front side of the device, and the front panel is provided with illumination means for irradiating the insertion / extraction port. Can be achieved with equipment.
With this configuration, it is possible to irradiate the insertion / extraction port even when the portable device is attached / detached. Moreover, since the illumination means is provided on the front panel, it is possible to suppress an increase in the size of the main device. Moreover, since the illumination means is provided in the front panel, it can irradiate from a position close to the insertion / extraction opening, and the position of the insertion / extraction opening can be easily confirmed.

In the above configuration, the illumination unit includes a light source and a light guide plate that guides light from the light source, and the light source is provided on a substrate built in the front panel adjacent to the housing recess. In addition, the light guide plate may adopt a configuration adjacent to the housing recess.
With this configuration, interference with the storage recess can be prevented. Therefore, it is not necessary to downsize the portable device, and the space in the front panel can be used effectively.

In the above configuration, the light source can be configured to be provided on a surface where the number of components mounted on the substrate is small.
With this configuration, an increase in the size of the substrate can be suppressed.
