Title: Separation device for transferring material
Inventor: TSUNEMI TAKEO
IPC: G03G15/16
Filed: 1992-06-19
Abstract: PURPOSE:To make the attaching adjustment of a guiding part unnecessary and to eliminate the joint between parts so that such a problem that a transferring material is caught may be eliminated by integrally forming a supporting part supporting an electrode for destaticizing and the guiding part guiding the transferring material toward the upper part of the electrode. CONSTITUTION:The guiding part 19f on a downstream side is formed higher than the guiding part 19e on an upstream side by the guiding parts 19e and 19f of a destaticizing holder 19b on the upstream side and a holder 19a on the downstream side; therefore, the leading edge of the transferring material does not receive large shock, because the leading edge is slippery even though the leading edge of the transferring material is brought into contact with a pawl part at a certain angle from an upper part with respect to a horizontal direction in a figure, and even though the leading edge of the transferring material projectingly curled upward is brought into contact. The holder 19b is a separate component from the holder 19c and is independent; however, each component constitutes the guiding parts 19e and 19f by integral forming. Thus, adjustment, etc., are not required, and the high accurate carriage surface of the transferring material can be formed.
