Abstract: In an electric safety switch circuit for use in apparatus having at least one safety switch for detecting at least one abnormal condition of the apparatus, switching elements are connected between a power source and the apparatus. The voltage of the main power source is transformed to a lower voltage and the switching elements are opened or closed by control circuitry in the low voltage circuit. The at least one safety switch is connected to the voltage transformer and the control circuitry such that the actuation of the at least one safety switch upon detection thereof of an abnormal condition actuates the control circuitry to open the switching elements and disconnect the apparatus from the power source.In one embodiment a primary switch is interconnected between the power source and the electric safety switch circuit, and in a modified embodiment the primary switch is connected in the electric safety switch circuit itself. The reduction in the voltage and current in which the primary switch and/or the at least one safety switch are interconnected results in improved reliability, durability, and operating life of the electric circuit as well as providing commensurate decreases in the cost of the electric circuit.

Abstract: An electrostatic latent image transfer type copying apparatus which has a photoconductive member, a system for forming an electrostatic latent image on the photoconductive member, an image transfer system for conducting transfer material having an insulating dielectric layer coated over an electrically conductive layer into contact with the photoconductive member for transferring the latent image onto said transfer material, a transporter for the transfer material to transport it along a predetermined path to the image transfer system, a member such as a relatively sharp edge member like a cutter provided along the path and below which the insulating dielectric layer side of the transfer material passes, and an insulating member provided adjacent the sharp edge member for preventing the surface of transfer material from contacting the sharp edge member as the transfer material is transported, whereby the contact of the sharp edge member with the surface of transfer material which causes frictional charging on the transfer material is substantially prevented.
