PURPOSE:To change the mumbers of tip type integrated circuit to be mounted by a method wherein a separator the size of which is changeable is provided on an additional module. CONSTITUTION:A cassette case 8 is formed to be removably inserted into the lower case 2' of an electronic device. The case 8 contains an additional module 20 comprising insulators 9, 9' and a separator 10 inserted between these insulators 9, 9'. A printed circuit 11 penetrates into the slots 9c, 9c' of the insulators 9, 9' and LSI 12 is mounted on the under surface of the printed circuit 11. The contact terminals 13 come into contact with the contact patterns 5a on the printed circuit substrate 5 through the holes 9b, 9b' formed into the insulators 9, 9, and the holes 2a' on the case 2'. The numbers of LSI 12 may be changed by means of changing the size of the separator 10 and the insulators 9, 9'. |
