摘要： A print wheel printer includes a trigger unit casing and a main housing frame, a plurality of print wheels rotatably mounted on a print wheel shaft and having a corresponding ratchet wheel secured to one side of each print wheel. A plurality of rotatably mounted selective pawls are supported on the trigger unit casing for stopping the rotation of the print wheels at selected print wheel engagement positions wherein a corresponding pawl is rotated into position to engage a corresponding print wheel ratchet wheel. A rotatable reset lever is also mounted on the trigger unit casing for the purpose of returning the selective pawls to a print wheel disengagement position. The selective pawls and the reset lever are both supported on the trigger unit casing in a prealigned relationship and support means are provided on the main housing frame for supporting the set of print wheels. Interengagement means on the trigger unit casing and the main housing frame provide for securing the casing onto the main housing frame whereby positional alignment of the casing selective pawls relative to the print wheel ratchet wheels is achieved without need for any further after-assembly adjustment.

摘要： The type wheels provided on a postage or franking head of a postage meter or franking machine are adjusted in stepwise manner from outside the franking head by means of adjusting push rods, which in each case engage a pinion associated with a type wheel. The engagement and adjusting movement of the adjusting push rod is performed by electromagnets. The engagement movement takes place by pivoting a guide plate carrying the adjusting push rods, on which the rods are displaceable by means of the electromagnet counter to the tension of a tension spring. The electromagnets can be energized on the basis of an electrical pulse, which is simultaneously used for adjusting an electronic display, provided on the franking machine casing.

摘要： A printer for printing a row of characters on a recording medium. The printer includes at least first and second type rings having types disposed on the periphery thereof which are rotatable from a reset position to a print position. First and second pawls are associated with the first and second type rings, respectively. A control member moves the first pawl into engagement with the first type ring when in its reset position to prevent rotation thereof. The second type ring is rotated into a print position while the first type ring is held in its reset position by the first pawl. A lever associated with the first and second pawls is actuated by an electromagnet to move the second pawl into engagement with the second type ring when in a print position to stop the rotation thereof. The control member releases the first pawl from the first type ring which then rotates to a print position. The lever is then reactuated by the electromagnet to move the first pawl into engagement with the first type ring when in a print position. A positioning member positions the second pawl out of engagement with the second type ring and also acts to hold the second pawl in engagement with the second type ring when the second pawl is moved into engagement with the second type ring.

摘要： A printing mechanism is disclosed which has a cylindrical type wheel rotatably supported on a driving shaft and carrying a plural number of types arranged on it circumferential surface at regular angular intervals and protruding from the surface. For effecting printing, one of the types is selected and the selected type is struck against a recording medium making use of a energy of rotation. The present invention is directed to improvement in such type of printer. The improvement comprises an elastic member through which the type wheel is supported on the driving shaft. The elastic member is fixed to the driving shaft. The type wheel is disposed concentrically with the driving shaft and spaced from a platen by a determined distance. The elastic member is engaged with projections formed on the inner circumferential surface of the type wheel so as to transmit rotation of the driving shaft to the wheel. After selecting a time point for printing a selected type, the type wheel is stopped rotating and moved, as a whole, toward the platen eccentrically to the driving shaft so as to strike the selected type against the platen for effecting printing. After printing, the elastic member is disengaged from the inner projections thereby allowing the type wheel to move back toward the driving shaft while the type wheel being still in the state substantially stopped rotating.

摘要： A compact print wheel position sensing device for parallel-wheel printers includes pairs of optoelectronic printed circuit emitters 22 and receivers 24 arranged in two lines inside and outside, respectively, a tubular shaft 21 provided with radial holes 23 aligned with each emitter/receiver pair and carrying wheels 19 which mesh with corresponding parallel print wheels 11. Each wheel 19 has a set of angularly spaced transparent regions, alternating with opaque regions, which permit transmission between the corresponding emitter/receiver pair at each printing position of the respective print wheel. A logic device includes a memory arranged for storing printing wheel position orders and having double reading heads for each division. A double electronic switch is connected to the heads to read the divisions in numerical sequence, each division being read twice per cycle, the earlier reading head controlling electromagnetic latches for stopping each print wheel at the ordered position and the later reading head subsequently delivering the order signal for comparison with the resulting wheel position, thereby compensating for mechanical actuation delay of said electromagnetic latches.

摘要： A serial printing device comprises a type head mounted rotatably on a carriage which is slidable along a printing line of an office machine. A continuously rotating driving shaft is connected to a differential mechanism which normally transfers the motion to the type head for the selection of the character to be printed. A selectively actuatable electromagnet arrests the rotation of the head in the printing position and simultaneously transfers the motion of the driving shaft to a striking mechanism to effect the printing of the selected character. A positioning element, commanded by the striking mechanism at the actuation of the electromagnet, keeps the head locked during the striking movement and the electromagnet is immediately deenergized. After the striking of the selected character the head is freed by the positioning element and is set in rotation again.

摘要： A positioning mechanism for moving a cylinder axially and rotationally is adapted for a printer which has a cylindrical type carrier on which the dies are arranged in intersecting rows and columns. A first electrically conductive coil is coaxial with and mounted on one end portion of the cylinder. A second electrically conductive coil has an axis perpendicular to the axis of and is mounted on the other end portion of the cylinder. A pair of permanent magnets are positioned about opposite end portions of the cylinder such that each coil is disposed for magnetic coupling in the magnetic flux field of a corresponding magnet. By selectively energizing the coils, magnetic effects are produced thereabout for coaction with the permanent magnetic flux fields simultaneously to drive the cylinder axially of and angularly about its axis. A feed back system for sensing the instantaneous longitudinal and angular positions of the cylinder is adapted simultaneously to provide electrical effects, whereby from any axial and angular conditions the cylinder can be driven to any other selected axial and angular conditions.
