Abstract
An apparatus for conveying magazines which are for electronic devices such as semiconductors, etc. including a magazine pusher that pushes the magazines placed on a magazine stand toward an elevator, slide rails that are movable back and forth between the magazine stand and the elevator, and a slide rail pusher that drives the slide rails. When all the magazines on the magazine stand are pushed by the magazine pusher and the front most magazine among them is transferred onto the slide rails, slide rail pusher brings the slide rails to the elevator so that the elevator lifts the magazine to a predetermined height so that electronic devices are brought into or out of the magazine. Thus, many magazines are placed on the magazine stand without inviting any positioning errors, and the apparatus can meet any change of the size of the magazines to be conveyed.
