摘要:
A paper feed device according to the invention comprises a paper feed cassette accommodating paper sheets and a paper feed mechanism for feeding out paper from the cassette. It also comprises a manual paper supply guide provided on top of the cassette for advancement and retreat therealong and having a paper guide surface for guiding manual supply paper. The detection of whether paper is present in the paper feed cassette and also the detection of a paper sheet being fed over the manual paper supply guide in a manual paper feed supply mode are effected by a single detecting switch.

A microfilm reader printer has a reader unit which projects a microfilm image onto a screen and a printer unit which reproduces copies of the microfilm image. The printer unit has an optical device for forming an electrostatic image on a photoreceptor by exposing the microfilm image onto the photoreceptor and a developing device for visualizing the electrostatic latent image formed on the photoreceptor. The developing device has a first developing unit for achieving direct development, a second developing unit for achieving reversal development and driving device for activating one of the developing units. A positive copy may be reproduced from both positive and negative types of a microfilm by selectively operating one of the developing units.

An image forming apparatus with a color agent coated supply medium, a first recording medium and a second recording medium. The color agent is transferred selectively to the first recording medium to form a first pattern on the color agent supply medium and a second pattern on the first recording medium. One of the patterns is used for displaying and the other is transferred to the second recording medium for recording.

A thermal transfer color printer for printing color images on individual sheets of paper. One sheet of paper at a time is removed from a stack of paper stored in a cassette and this sheet is transported by a reversible platen roller in a first or forward direction at a first predetermined rate. While the sheet of paper is gripped between the reversible platen roller and one or more pinch rollers, slack is removed by a slack removing device. A multicolored ink ribbon with successively arranged color segments also is transported in the first direction at the same predetermined rate. A thermal printhead presses against the reversible platen roller to press the ink ribbon and sheet of paper together as they move in the first direction. Energization of the thermal elements on the thermal printhead by color component signals corresponding to the current color of the ink ribbon causes the particular current color to be thermally and selectively transferred to the sheet of paper. The thermal printhead then disengages the platen roller and the sheet of paper is transported in a set distance in a second direction opposite the first direction, and at a second predetermined rate, in order to repeat the process of thermally transferring other colors to the sheet of paper. During the back and forth movement of the sheet of paper, the reversible platen roller and the pinch rollers continuously grip the sheet of paper in order to precisely control the position of the sheet of paper to thereby avoid distortion. A complete color image is formed on the sheet of paper by superimposing the multiple colors of the ink ribbon as the sheet of paper and the different colors of the ink ribbon repeatedly move past the selectively energized thermal elements of the thermal printhead.

An image reading device having a document handling system is suitable utilized on a modified standard office copier as electronic copying machine. In particular, the document presser plate is composed of a presser plate which is provided on the cabinet of the device. The document presser plate is held selectively over the exposure glass surface in two or more positions and used as the document feed tray in automatic document feed. When using this invention, the document presser plate functions as a document feed tray and a document dispense tray, there is no requirement for special feed and dispense trays. A compact and light-weight unit can therefore be achieved.

According to one embodiment, an image forming apparatus includes a printer section and a control section which controls the printer section. The control section controls a developing roller driving section to stop the rotation of a developing roller when an image on a recording medium is erased when the printer section operates in an image erasing mode, alternatively, the control section includes an image formation fee counter and an erasure fee counter provided separately from the image formation fee counter.
