Abstract

A carriage driving mechanism moves a paper cassette forward and backward along a feeding direction. A cassette rotating mechanism rotates the paper cassette. A single carriage driving mechanism and a single cassette rotating mechanism are provided for each paper cassette and installed on a level between a cassette circular plate and a large turntable. The carriage driving mechanism includes a driving system constituted by a pulse motor, a series of gears, a pulley, a carriage, a wire wound around the pulley, and guide bars. The cassette rotating mechanism includes a pulse motor and a series of gears. The driving system of the carriage driving mechanism and the cassette rotating mechanism are mounted on the bottom surface of the carriage so as to be level, and move along with the carriage. This configuration enables a reduction in the height and size of a rotatable cassette-type feeding apparatus and an increase in copying functions.

Claims7

Dependent claims

A rotatable cassette-type feeding apparatus, comprising:

base means for carrying said rotatable cassette-type feeding apparatus;
storing means for storing copy material on which an image on a document is to be copied and for feeding the copy material from a predetermined feeding position;
carrying means installed on said base means for carrying said storing means, said storing means being rotatable and movable forward and backward in a first direction on said carrying means, and wherein the first direction is a radial direction of rotation of said carrying means;
first rotation driving means installed between said base means and said carrying means for rotating said carrying means;
second rotation driving means installed between said storing means and said carrying means for rotating said storing means;
moving means installed between said storing means and said carrying means for moving said storing means in the first direction, said moving means being level with said second rotation driving means;
first rotation controlling means which controls said first rotation driving means to align the center of the copy material with a transport center line when the copy material is fed;
second rotation controlling means which controls said second rotation driving means to switch a position of the copy material with respect to a second direction in which the copy material is fed and to position a leading edge of the copy material fed from said storing means at right angles to the second direction;
movement controlling means which controls said moving means to move said storing means to the feeding position;
and
wherein said second rotation driving means is mounted on said moving means and is moved in the first direction together with said storing means.
