    Abstract: A variable magnification copying apparatus capable of not only one-to-one magnification copying but also reduction copying, and particularly a variable magnification copying apparatus of the slit exposure scanning type which is capable of two or more types of reduction copying and which uses two movable mirrors and an in-mirror lens on the object side, characterized in that the optical axis of the in-mirror lens is set non-parallel to an original carriage to make the apparatus compact and during magnification change, the in-mirror lens and the second movable mirror are initially displaced by predetermined distances in predetermined directions, whereby the object point position and image point position of an image forming principal light ray on the original supporting surface and photosensitive surface are made fixed irrespective of the copying magnification.

    Abstract: In a TEDS system, a data transmitting and receiving apparatus is provided and a signal transmitted from a TEDS memory to an apparatus side is logically inverted without using a transformer, and further a sneak signal is prevented.Inverters 28, 30 and zener diodes 32, 34 connected in parallel between the TEDS memory and a data driver of the apparatus are provided. Data transmitted from the TEDS memory to an apparatus 18 side is logically inverted by the inverter 28, and the logical voltage attenuates by a predetermined amount at the zener diode 32 to be supplied to the data driver. Since a sneak signal 100 whose logical voltage attenuates by a predetermined amount again by the zener diode 34 is supplied to the inverter 30, the transmission of a logic value is prevented by setting the threshold of the inverter 30 appropriately.
