摘要： A sheet moistening device comprises a pair of moistening rollers which respectively have porous layers and form a nip to convey a sheet, and a dampening mechanism which supplies water to at least one of the pair of moistening rollers through a surface thereof. In the sheet moistening device, a roller surface hardness differs between the pair of moistening rollers. In addition, the sheet moistening device can further comprise a regulating device which regulates an amount of water to be supplied from the dampening mechanism to the moistening roller.

摘要： A duplicating machine has an impression roll positioned to press copy sheets against a master sheet on a drum which is rotatable by an electric drive motor through a coil spring type clutch. The clutch consists of a coil spring having an interference fit with cylindrical friction surfaces on driving and driven clutch members which are connected respectively to the motor and drum. The coil spring is helically wound in a direction to tighten the interference fit when the motor rotates the driving clutch member to turn the drum in a printing direction; conversely, the interference fit loosens when the driving end of the coil spring is held, enabling the driving clutch member to rotate freely. A tang on the driving end of the spring is positively connected to a cylindrical release collar surrounding the spring. The driven end of the spring has a positive tang connection to the driven clutch member and drum. Thus, rotation of the release collar and drum are synchronized within a range determined by the torsional elasticity of the spring. A stop arm is movable to and from a stop position engaging one or more detent recesses in the release collar. Engagement of the stop arm within one of the recesses, at the end of a printing run, automatically stops the collar. This disengages the clutch by releasing the interference fit between the spring and the driving clutch member. The drum stops at a position determined by the stopped position of the release collar. A plurality of detent recesses are circumferentially and axially spaced about and along the axis of the release collar. The stop arm is selectively engageable with one or the other of the recesses to stop the drum at different rotated positions to enable the ends of different length master sheets to clear the impression roll. A manually operable starter arm assembly releases the stop arm from the detent recess on the release collar and simultaneously closes a switch to actuate the drive motor. Conversely, when the last copy sheet is fed into the machine, the stop arm automatically drops into the selected recess to stop the release collar to disengage the clutch while simultaneously opening the switch to deactuate the driving motor and allow the drive train to coast to a stop.

摘要： An electrophotographic copier unit and an offset printer unit are combined together to constitute a copying-printing apparatus in accordance with the principles of the present invention, which utilizes an electrophotographic process to accomplish offset printing, utilizes preferably the wet type development to develop an electrostatic latent image, and utilizes an image transfer system to transfer the developed image to a transfer sheet. Such transfer sheet may in turn be used as an offset master sheet. Thus, the apparatus can perform copying and printing operations at high speeds and produce multiple copies in a short time and in an economical and hygienical manner.

摘要： A PRINTING MECHANISM INCLUDING AN ORDINAL SERIES OF DIGITAL PRINTING WHEELS IS SET TO SELECTED DIGITAL POSITIONS BY AN ELECTRIC CONTROL CIRCUIT INCLUDING AN ORDINAL SERIES OF DIGITAL SETS OF MANUALLY OPERATED KEY SWITCHES. AFTER ACTUATION OF A KEY SWITCH FOR EACH PRINTING WHEEL, A START SWITCH IS OPERATED WHEREUPON THE PRINTING WHEELS ARE AUTOMATICALLY SET TO THE SELECTED PRINTING POSITION. THE MECHANISM IS BUILT INTO A CAVITY OF A PRINTING CYLINDER SO THAT A COPY SHEET IMPRINTED BY THE SAME IS ALSO IMPRINTED BY THE PRINTING WHEELS. IT IS ALSO POSSIBLE TO ARRANGE THE PRINTING WHEELS IN THE PATH OF MOVEMENT OF A COPY SHEET IMPRINTED IN A PRINTING MACHINE, AND TO USE THE PRINTING WHEELS TO PRINT ADDITIONAL INFORMATION ON THE COPY SHEET.
