Title: Lead frame detecting device
Inventor: MOMO TOSHIAKI
IPC: H01L21/50
Filed: 1978-07-12
Abstract: PURPOSE: To detect presence of lead frame by shutting off a light passage of photo coupler with a piece moving up and down synchronously with conveying pitch of the lead frame.  
     CONSTITUTION: A movable piece 4 is moved up and down by rotation of a shaft 1 operated synchronously with conveying pitch of a lead frame 15. A tongue-like piece 4 contacts a bridging slim strip 15 of the lead frame, and when the lead frame 15 is absent, the tongue-like piece 4 enters as deep as inside of a groove 14 of the conveying jig 13 to shut off a light passage of photo coupler 12. It is possible, by doing so, to detect presence of the lead frame.
