STRUCTURE OF PREVENTING MISSING OF SUBSTRATE OR ELECTRONIC COMPONENT, AND PORTABLE MACHINE

PROBLEM TO BE SOLVED: To provide a structure of preventing the missing of a substrate which can prevent from being assembled in a state that the substrate is not installed cases, and to provide a portable machine. SOLUTION: A resin holder 8 required for assembling an upper case 4 and a lower case 5 is attached to the edge of a substrate 2. The holder 8 is fixed to the substrate 2 by adhesion, welding, or other methods. On the inner surface of each end of the upper case 4 and lower case 5, projections 10 and 11 are formed circumferentially along the opening end of each case. On the external surface of the holder 8, there are formed engagement grooves 12 and 13 so as to be engaged with the projections 10 and 11. The upper case 4 and the lower case 5 are integrally assembled to each other by a snap fit structure wherein the projections 10 and 11 of the cases 4 and 5 are fit in with the engagement grooves 12 and 13 of the holder 8 without using an adhesive.
