The lead frame is preliminarily cut by a device such as a cutting press and is made into a predetermined size, thereby maintaining a standby state. The cassette CA can be supplied by a conveying means such as a conveyor and moved to a predetermined position. Then, the idle sheet can be placed between the layers of the lead frame while the standby lead frame is loaded on the cassette CA. Thereafter, the cassette (CA) loaded with all the lead frames can be discharged along the discharge conveyor. The auto stacker 10 according to the present invention automatically performs a series of processes such as feeding of the cassette, loading of the lead frame, and discharging of the cassette.

For example, the cassette ejecting module 17 on the left side and the cassette ejecting module 17a on the right side can have the same or similar structure and perform the same or similar functions. Therefore, only one module is described unless it is specifically required for the sake of brevity below.
