A desk-top electrostatic copying machine comprising a lower section, an upper section pivotally attached to the lower section, and a front section pivotally attached to the upper section. The lower section contains a copy paper charging station, a copy paper exposure station, and a copy paper developing station, all disposed along a copy paper flow path. The copy paper flow path is defined by bottom elements carried by the lower section and top elements carried by the upper section, so that when the upper section is opened the flow path of the copy paper is exposed. The upper section contains an original paper illuminating station and an optical system for projecting the image of the original paper from the illuminating station to the copy paper exposure station. An original paper flow path is defined by bottom elements carried by the upper section and top elements carried by the front section so that when the front section is pivoted to the open position the flow path of the original paper is exposed.
