A document feeding apparatus having both an automatic and manual feed mode. the apparatus includes a paper feeding belt for feeding documents from a stack set on a document stacker, wherein the lowermost document in the stack is fed, and a stop roller placed in contact with an upper surface of the paper feeding belt to prevent the overlapped feed of documents. Documents are fed through a common paper path in both modes. The belt and roller are commonly used in both the automatic and manual document feed modes. In the automatic document feed mode, the belt is driven while the roller is held in a non-rotational state. In the manual document feed mode, the belt is driven and the roller is driven by the belt.

Document feeding apparatus and reproducing machine having document

A recording apparatus includes an electrostatic image support and a fixing device. The toner image formed on the electrostatic image support is transferred onto a copy paper, and the copy paper is separated from the surface of the electrostatic image support and then fed to the fixing device to fuse the toner image, for example by heat. A device is provided for distinguishing the relation in the length between the distance (A) from the separating position at which the copy paper is separated from the electrostatic image support to the fixing position of the fixing device, and the length (B) of the copy paper in the transport direction. A control device controls the relative circumferential speeds of the electrostatic image support and the copy paper transport apparatus provided inside the fixing device as a function of the distinguished relation between said lengths (A) and (B).

Recording apparatus with speed control

The slit exposure optical system for a copying machine generally includes two mirror-carrying movable tables of which one is driven at half the speed of the other. Normally each table is driven from one and the same end which means that the other end of each table must follow. If such following is not precise, aberrations in the optical system result. The present invention provides means for interconnecting the nondriver ends of the tables in such a manner that the movement of the nondriver ends will precisely follow the movement of the driver ends and aberrations are thereby avoided.

Split exposure optical system for copying machine

In the optical system of an electrophotographic copying apparatus embodying movable mirrors, it is of the utmost importance that these mirrors be properly aligned relatively to one another. In the present invention, two of the mirrors mounted at right angles to one another on a slidable frame which moves at half the speed of another movable mirror, are mounted on that frame for slight pivotal movement. This pivotal movement is controllable to provide adjustment of errors in the optical system and when adjustment is completed the mirrors are fixed in place.

Adjustable mirror support for copying apparatus

An electrophotographic reproducing apparatus in which a reproducing apparatus body unit including an electrostatic latent image receptor such as a photosensitive member and other electrophotographic treating device is assembled in advance whereas an optical scanning unit including at least a document illumination lamp, a group of mirrors and a group of focusing lenses is assembled in advance in a predetermined positional relationship to the reproducing apparatus body unit, and both the units thus assembled are jointed at predetermined reference planes to each other and so integrated that they can be driven cooperatively with each other. Said two units further include jointing device at their respective predetermined reference planes.

Electrophotographic reproducing apparatus

A shock absorbed device for reciprocating a driven member includes a bidirectionally rotatable driving pulley, a pair of fixed pulleys between which the driven member is disposed, an oscillating pulley arranged between the driving and fixed pulleys, and at least a wire connecting all said pulleys. The oscillating pulley is mounted for free movement along a path from a neutral position centrally within its path in response to rotation of the driving pulley in either direction thereof.

Reciprocating driving device

A fixing apparatus includes a first, heated roller and a second roller movable from spaced apart condition in their nonoperative mode into mutual pressure contact with each other for operatively fixing a toner image to a support sheet passed therebetween, and a cleaning blade maintained in continuous contact with the first roller to clean contaminating matter from its surface. In operation, the first roller is rotated through at least one full revolution prior to contact with the second roller so that residual contaminating matter can be cleaned from the first roller surface before contact with the second roller and image fixing take place.

Heated roller type fixing apparatus

A recording apparatus having a roller type fixing device made up of a first roller and a second roller for fixing the image to the transfer paper. The recording apparatus has an upper guide plate placed over the transfer paper passage on the inlet side of the roller type fixing device, the upper guide plate being curved down gradually toward the front end and extending near the lower portion of the first roller. The upper guide plate has on its underside a plurality of projecting strips extending in the direction of the paper feed.

Recording apparatus having roller type fixing device

An apparatus for measuring a temperature comprising a temperature measuring element. Said temperature measuring element is arranged closely to a surface of an article whose temperature is to be measured, an electric property of said temperature measuring element being varied corresponding to a temperature variation, and lead wires of said temperature measuring element are arranged so as to stretch closely to and along by the surface of said article.

Apparatus for measuring temperature

A roller type fixing apparatus for an electrophotographic copying machine comprising a fixing roller, a pressing roller disposed to confront and have contact with said fixing roller and a mechanism for rotating said fixing roller and press roller. At least one of said fixing roller and press roller has a peripheral surface layer portion composed of a resinous material and a low electric resistance powder incorporated therein and said peripheral surface layer portion is electrically grounded.
