Description

  The present invention relates to an in-vehicle electronic device, and more particularly to an operation button mounting structure thereof.

  An example of a conventional operation button mounting structure for an in-vehicle electronic device such as a DVD player will be described with reference to FIG. The length of the casing 1 of the in-vehicle electronic device shown in the figure is limited within the depth direction limit A (maximum 160 mm) from the device mounting surface P of the vehicle. A sub-panel 10 is attached to the front surface of the housing 1, and an openable / closable monitor 7 is attached to the subpanel 10 so as to be freely opened and closed.

  The openable monitor 7 is driven manually or by a drive mechanism between a closed position indicated by a solid line and an open position indicated by a two-dot chain line. An operation button 11 is disposed at a position behind the openable monitor 7 of the sub panel 10. The operation button 11 is inserted through the hole 10 a of the sub-panel 10 and is urged forward by an operator of the switch 5 attached to the printed circuit board 4 disposed behind the operation button 11.

  In the above-described conventional operation button mounting structure, the operation button 11 cannot be disposed at the upper part of the sub-panel 10 because the disk insertion slot is provided in front of the recording medium playback mechanism 8, and the lower part of the sub-panel 10 is opened when the openable monitor 7 is opened. Moreover, since it is hidden behind the openable monitor 7, it cannot be placed below the sub-panel 10.

  Then, in order to prevent interference with the open / close type monitor 7 when the open / close type monitor 7 is in the closed position indicated by the solid line, the projecting dimension (d in the drawing) of the operation button 11 from the surface of the sub-panel 10 is increased. I could not. For this reason, there is a problem in that the hang of the finger on the operation button 11 becomes small and the operability is poor.

The self-illuminating button proposed in Japanese Utility Model Publication No. 5-34622 illuminates the entire button without light unevenness while reducing the height from the printed board surface to the surface of the operation button. However, when this self-illuminating button is placed behind the openable monitor, the amount of protrusion from the sub-panel placed behind the openable monitor cannot be increased in order to prevent interference with the openable monitor. The problem of bad nature occurs.
