Abstract: A printer is provided with carriage having a daisy print wheel supporting type elements at the external circumferential edges of respective spokes that make up the wheel. The printer sequentially performs a printing operation by causing its carriage to move in the direction of a printing row and a hammer to strike the designated type element held by an associated print wheel spoke after rotating the designated type element into the printing position. The daisy print wheel includes a number of spokes each mounting a type element at its external circumferential edge. At least one of these spokes is provided with a pen at the position corresponding to that of the type element held by the remaining spokes, and as a result, by selecting the pen from the type element supported in the remaining spokes, either a picture, diagram, or a graph can be optionally drawn, thus effectively realizing a multifunctional printer.

Abstract: Sheet-fed rotary printing press for single-side multicolor printing or for first form and perfector printing having a plurality of printing units disposed in tandem and having devices for processing both paper as well as heavier paperboard, each of the plurality of printing units having a plate cylinder and a blanket cylinder of equal given diameter in mutually cooperative relationship as well as an impression cylinder operatively engaging the blanket cylinder and having a diameter double the given diameter, and a sheet transfer cylinder in mutually cooperative relationship with the impression cylinder, each of the printing units includes an upper part and a lower part, the lower part thereof having two opposite side walls each formed with two bearing holes, respectively, located vertically above one another for receiving therein respective bearings for sheet transfer cylinders, the lower of the two vertically disposed bearing holes being of such size as to accommodate a bearing for a journal of a sheet trans

Abstract: A printing unit of an offset rotary printing machine for printing a paper web with an endless impression, the printing unit having two plate cylinders with respective printing plates disposed on half the respective peripheries thereof for providing respective partial prints successively includes at least one blanket cylinder operatively associated with the two plate cylinders, an applicating roller equal in size to that of one of the plate cylinders disposed for simultaneous engagement with both of the plate cylinders, an inking unit and a dampening unit operatively connectible via an inking cylinder with both of the plate cylinders for delivering ink and dampening fluid thereto, a sum of distances starting from a contact location at which successive partial prints provided by the two plate cylinders become united and extending via the at least one blanket cylinder, one of the plate cylinders and the inking cylinder back to the contact location corresponds to a multiple of the periphery of one of the two plat

Abstract: A portable, handheld data recorder for pressure-transfer printing embossed information onto a form set from a credit card or the like includes a push/pull platen assembly contained in a closed housing but manually operable from the exterior of the device. A releasable retainer also within the housing is provided for holding the form set in place during imprinting and again is manually operable from the exterior of the device. The recorder also includes resilient means for accommodating credit cards of different thicknesses.

Abstract: An apparatus for producing a reset pulse for performing the printing operation of an impact printer. A cam is secured to a shaft of a type drum. The cam has a rising portion, lowering portion, and escape portion. A cam follower is mounted on a lever to engage with the cam. The cam follower has a large diameter portion and a small diameter portion, and a reset switch is provided to be operated by the lever to produce a reset pulse when the lever is rocked by the engagement of the cam follower with the lowering portion of the cam.

Abstract: A printing unit with a short inking unit, the printing unit having mutually engageable impression, blanket and plate cylinders and at least one applicator roller having a size comparable to that of the cylinders for feeding both dampening medium and ink includes an inking cylinder, the inking cylinder and the plate cylinder being disposed relative to one another and to the blanket cylinder in a manner that the blanket cylinder is selectively engageable alternatively with one of the inking cylinders and the plate cylinder, the blanket cylinder being coverable selectively by a blanket and a rubber block, the inking cylinder having a ductor blade engageable therewith, the applicator roller being separated from the inking cylinder in a condition of the printing unit wherein the blanket cylinder is covered by the rubber block and is in direct cooperative engagement with the inking cylinder.

Abstract: A leaf spring unit has a leaf spring cantilevered on a supporting member, an armature secured to one side of a free end portion of the leaf spring, and a wire secured to the armature. A reinforcement plate is secured to the other side of the leaf spring opposite to the armature. An inner edge of the reinforcement plate is inwardly extended from the inner side of the armature so as to reinforce a part of the leaf spring.

Abstract: The device comprises two or more cover plate members (14), whose lengths are submultiples of the lengths of a range of platen rollers (12) and such that two or more plate members disposed in side-by-side relationship cover the entire length of the platen roller. Each plate member (14) comprises a lower guide portion (16) of part-cylindrical shape and two wall portions (17, 18) which are substantially planar and set at different angles of inclination, being connected to the lower guide portion in such a way to lead in a sheet of paper (19) towards the guide portion. Each plate member (14) is pivotally mounted on a control shaft (22) which is parallel to the axis of the roller (12) and capable of preventing transverse movements of the plate member with respect to the roller, and carries the usual paper pressing rollers (34, 36) which are disposed in two parallel rows. A leaf spring (26) co-operates with a lug (24) on the plate member (14) to hold the paper pressing rollers pressed against the platen roller.

Abstract: This invention relates to a page printer having an electro-thermal dot-matrix printing mechanism. The latter comprises at least one print plate which is disposed parallel in relation to the print line and radially in relation to the platen, which is hooked at both ends into a tensioning device. The print plate consists of a carrier plate made of material having relatively good electrical and heat-conducting properties. It is applied with its front surface to the thermo-sensitive recording medium on which recordings are made via a plurality of closely adjacent heating elements. These heating elements are deposited onto at least one of the lateral faces of the carrier plate, made flush with the front surface, and are conductively connected to the carrier plate. The remaining part of each of the lateral faces is covered, throughout the widths of the heating elements, with a layer of insulating material on which the conducting paths extending to the heating elements are disposed.
