    摘要: The polyimide film of this invention is formed from a polyimide, which is prepared by reacting a diamino compound represented by the general formula (1): ##STR1## wherein X represents a hydrocarbon group having 1 to 20 carbon atoms or a sulfur atom; R represents each independently a halogen atom, a hydrocarbon group having 1 to 6 carbon atoms or a halogen-containing hydrocarbon group having 1 to 6 carbon atoms; a represents each independently an integer of 0 to 4; with a tetracarboxylic dianhydride represented by the general formula (2) ##STR2## wherein Y represents a tetravalent organic group having 2 or more carbon atoms. The polyimide film obtained can be applied favorably to a flexible printed circuit board without adhesion layer, a protective coating for electronic parts and electric wires, or a heat resistant adhesive.

    摘要: A sheet member discharge mechanism comprising an upper discharge roller and a lower discharge roller for conveying a sheet member in a predetermined direction while nipping it therebetween. A push-down member is disposed downstream of the nipping portion between the upper discharge roller and the lower discharge roller as viewed in a direction of conveying the sheet member, the push-down member being allowed to move between an ascended position and a descended position and is urged to the descended position. The push-down member is moved to the ascended position by the sheet member acting upon the push-down member while the sheet member is being conveyed by the upper discharge roller and the lower discharge roller that work in cooperation. The push-down member moves to the descended position to push down the trailing edge of the sheet member after the trailing edge of the sheet member has passed the nipping portion between the upper discharge roller and the lower discharge roller.
