Electronic equipment system for vehicle
An electronic equipment system includes a housing 20 and a plurality of modules 31 to 35, which are removably built in and fixed to the housing 20. The modules 31 to 34 includes a liquid crystal display 31 a ; a graphic control circuit 32 a 1 and a navigation control circuit 32 a 2; an MD unit 33 a ; and a CD unit 34 a , respectively. The module 35 is formed through integration of control sections, such as constant-voltage circuits for power supply, which achieve a function that is common among the graphic control circuit and the navigation control circuit, the MD unit, and the CD unit. Thus, it becomes possible to replace only necessary one among the modules 31 to 34, thereby reducing cost necessary for upgrading of the system.
1. An electronic equipment system for a vehicle which includes an operation section, a plurality of peculiar sections each having a peculiar configuration for effecting a specific operation and being physically separated from other sections, a control section having a physically integrated portion which provides a common function to two or more physically separated peculiar sections, and a housing, said operation section, said plurality of peculiar sections, and said control section being mounted to said housing, and said system being configured in such a manner that in response to operation of said operation section, one peculiar section among said plurality of peculiar sections and said control section cooperate to provide the specific operation of said one peculiar section, said operating section having a plurality of switches each being electrically connected to at least one of said peculiar sections or to said control section via a switch circuit, wherein
said control section is configured to be mounted to and removed from said housing independently.
2. An electronic equipment system according to claim 1 , wherein
said housing is removably mounted to the vehicle and has an opening in a face which faces the rear of the vehicle when said housing is mounted to the vehicle; and
said at least one peculiar section and said control section are configured to be inserted into said housing from the opening of said housing and be removably mounted to said housing.
3. An electronic equipment system according to claim 2 , wherein
the opening of said housing is closed by a panel removably attached to said housing; and
said operation section is provided on said panel in a physically integrated manner.
4. An electronic equipment system according to claim 3 , wherein
the switch circuit is integrally provided on said panel.
5. An electronic equipment system according to claim 1 , wherein
said peculiar portions and said control section are formed on corresponding mounting substrates; said housing has a plurality of slits on an inner wall surface thereof; and said peculiar portions and said control section are fixed to said housing in a state in which edge portions of said mounting substrates are received by said corresponding slits.
