<p>PURPOSE:To accurately supply silicon wafers, on which IC, etc. are printing mounted, every one sheet without touching hands, by extracting matter to be worked, such as, wafers, etc. from a cassette by means of a belt, and by feeding the matter to be worked by means of a guide lever, which is installed along a belt for delivery continuously disposed and can freely be advanced or retreated, in a device that supplies the silicon wafers. CONSTITUTION:Wafers 3 housed in the housing grooves 57 of a cassette 54 every one sheet are extracted every one sheet by contact with an extracting belt 22 and sent to a delivery belt 25, and the postures are controlled so that rectilinear portions 34 be located at the nose by contact with a posture control roller 32. An oscillation arm 23 downward oscillates, the delivery belt 25 lowers and the wafers 3 are placed on a holding plate 41 of a nose of a guide lever 36, which can feerly be advanced or retreated, on the way of its fall. The extracting belt 22 and the delivery belt 25 stop, a feed belt 10 starts its functioning, a holder 8 unified with the belt 10 moves forward with the holding plate 41 and the wafers 3 on the holding plate 41 are supplied onto a working base 4.</p> |
