PURPOSE: To continuously perform surface treatment in a state where the occurrence of uneven treatment is reduced at the time of surface-treating a strip-like lead frame by electrolytic processing or electrolysis, such as electroplating, etc. ;CONSTITUTION: An endless carrying belt body 4 is provided above an electrolytic bath 1 incorporating electrode plates 2 and 3 so that the belt body 4 can move along the length direction of the bath 1 and hinge bodies 7 which clamp one end section of a strip-like lead frame are pivotally fit to the belt body 4 at a plurality of locations. On the other hand, a first guide body 11 which changes the attitude of each hinge body 8 from a nearly horizontal attitude to a nearly downward attitude and a second guide body 13 which changes the attitude of each hinge body 7 from the nearly downward attitude to the nearly horizontal attitude are respectively provided at both end sections of the bath 1.;COPYRIGHT: (C)1993,JPO&Japio
