<P>PROBLEM TO BE SOLVED: To reduce difference of intensity of light going outside from an eject button, between in a case where a card is inserted into an on-vehicle electronic device and a case where the card is not inserted. <P>SOLUTION: An eject button 3 guides light emitted by a light source 6 in a casing, in a projection direction of the eject button, and sends the light out of the casing. A lighting circuit of the light source 6 increases brightness of the light source 6 according as a card has been inserted into the casing from a card insertion port, and thereby making difference of luminous intensity on a surface of the eject button 3 in the projection direction between before and after the card is inserted less than in a case where, for example, the brightness of the light source 6 is not changed between before and after the insertion of the card. <P>COPYRIGHT: (C)2013,JPO&INPIT |
