Abstract
Abstract A mounting structure in which an electronic apparatus unit housed in a shield case is anchored directly on a circuit board in fixedly secured relation by fastening part of the shield case thereto. A space is created between the circuit board and a bottom plate of the shield case and part of the shield case which encloses the outer periphery of the electronic apparatus unit extends below the bottom plate to abut the circuit board and fixedly secure the shield case to the circuit board.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
176 words
A mounting structure for an electronic apparatus, comprising: a circuit board for printed wirings, said circuit board having fastening holes; a shield case forming first and second divided spaces, said shield case having protuberances on open edges thereof, wherein said protuberances are inserted into the fastening holes and said open edges are in contact with a surface of said circuit board; an electronic apparatus unit placed in one of the first and second divided spaces in said shield case, said electronic apparatus unit having a mounting base plate, parts mounted on said mounting base plate and input/output terminals, wherein said input/output terminals electrically connect said mounting base plate with said circuit board for printed wirings; and electronic parts placed in the other of the first and second divided spaces in said shield case and being shielded, said electronic parts being arranged on said circuit board surface and electrically connected to said circuit board for printed wirings, wherein said shield case has a bottom plate for dividing the first and second divided spaces in said shield case.
Claim 2
Dependent Claim
176 words
A mounting structure for an electronic apparatus, comprising: a circuit board for printed wirings, said circuit board having fastening holes; a shield case forming first and second divided spaces, said shield case having protuberances on open edges thereof, wherein said protuberances are inserted into the fastening holes and said open edges are in contact with a surface of said circuit board; an electronic apparatus unit placed in one of the first and second divided spaces in said shield case, said electronic apparatus unit having a mounting base plate, parts mounted on said mounting base plate and input/output terminals, wherein said input/output terminals electrically connect said mounting base plate with said circuit board for printed wirings; and electronic parts placed in the other of the first and second divided spaces in said shield case and being shielded, said electronic parts being arranged on said circuit board surface and electrically connected to said circuit board for printed wirings, wherein said shield case has a bottom plate for dividing the first and second divided spaces in said shield case.
Claim 3
Dependent Claim
