Abstract: The liquid container is detachable from a case of a liquid ejection apparatus. The liquid container has a bag-shaped member that is flexible and has a storage portion for storing a liquid therein, and a connection member attached to the bag-shaped member. The connection member has a liquid introducing outlet into which a liquid introducing portion of the liquid ejection apparatus is inserted, a container-side electrical connection unit to which an apparatus-side electrical connection unit of the liquid ejection apparatus is connected, and a handle that pivots with respect to the connection member. In a state where the liquid container is arranged in the case, the handle is provided at a position exposed to the outside of the case, and when the liquid container is mounted to/removed from the case, the handle is brought into a second orientation in which the handle is pivoted from a first orientation.

Abstract: In an ink supply amount control method for a printing press, ink is supplied from the gap between a plurality of ink fountain keys and an ink fountain roller to an ink supply path in accordance with rotation of the ink fountain roller. The swing operation of an ink ductor roller is temporarily stopped. When the swing operation should intermittently be stopped, the operation of the ink fountain key or the ink fountain roller is controlled to control the ink supply amount to the ink ductor roller. Ink in a corrected amount is supplied to a printing plate attached to a plate cylinder through the ink supply path by the swing operation of the ink ductor roller. An ink supply amount control apparatus is also disclosed.

Abstract: Webs of printable materials which are fed into a printing machine are provided with a feed tip that allows the web to be rapidly and releasably connected to a the web feed device. The feed tip has a thickened section which is generally perpendicular to the direction of web transport and which cooperates with a carrier element that is fastened to the web feed device. The carrier element has an oblong cavity which extends in the direction of web transport and which cooperates with the thickened portion of the web to form a stop that is perpendicular to the direction of web transport.

Abstract: A printing apparatus having a printing head comprising a plurality of coaxial, rotatable printing wheels, disposed substantially side-by-side and employing printing characters, and a control rotor for controlling the printing wheels and having its axis parallel to that of the printing wheels and positioned to be moved bi-directional to come into engagement with any selected printing wheel and then to be rotated about its axis to rotate the selected printing wheel for bringing into printing position a desired character thereon, comprising mounting structure mounting the control rotor toi) move axially parallel to the axis of the printing wheels,ii) move toward and away from the axis of the printing wheels,iii) rotate as aforesaid; and drive structure to effect the i) movement, the ii) movement and the iii) rotation.

Abstract: A device for adjusting the position of the printing head of a printer has a leaf spring received in a groove formed in the carrier of the printer. The spring is bent into a doglegged form such that the spring force is applied to both ends of the carrier backwardly. The printing head is mounted on a support plate which is provided with a groove with which the anchoring portions of the leaf spring engage. The support plate is mounted on the upper surface of the carrier so as to be slidable forwards and backwards by a counter-sunk screw.

Abstract: A hand-operated printer is disclosed which is suitable for imprinting ZIP codes on letters. The printer includes a printing lever which supports a printing head. Where only the numerals 0-9 need be printed, the printing head includes a printing wheel having raised type numerals thereon and a reading wheel geared to the printing wheel for selecting the numeral to be printed. Where a variety of characters must be printed, for example, the letters of the alphabet, the printing head includes a printing tape having raised type characters thereon and a reading tape geared to the printing tape for selecting the character to be printed. A clamping member is pivotally connected to one end of the printing lever and includes an aperture located opposite the printing head. The clamping member supports an inked ribbon which extends over the aperture.

Abstract: High speed, on-the-fly line printer apparatus including an inked ribbon advancing mechanism, a print sheet advancing mechanism, and drive structure coupled with both the advancing mechanisms to interruptedly advance them. Also, the inked ribbon advancing mechanism may be bodily shiftable between different positions associated with different color printing modes, the drive structure accommodating such shifting. Furthermore, a drum having multiple columns of type font segments is provided.

Abstract: A precision hand-held label imprinter and dispenser includes a compact case or frame with a projecting handle and an applicator roller located remote therefrom, together with a dialable imprinter and platen assembly arranged so that a trigger lever associated with the handle may be manually acutated in one direction to imprint label stock (tape) by driving the platen across an imprinter in an engaged condition to force the printing medium and label stock thereagainst and operates in the opposite direction to separate the imprinter and platen and to simultaneously advance the printing medium and to advance the printed label stock to the applicator roller. Through a series of connected drive elements with the trigger lever, the device times the several functions so that accurate reproductions with high resolution of the dialed imprint information on each label is assured.

Abstract: A label printing apparatus includes a main frame, a drum housing pivotably mounted in the main frame, and a printing drum, mounted in the drum housing, which comprises a plurality of discs each having a series of die groupings about its periphery as well as a groove associated with each die grouping. An assembly for setting each disc to place a selected die grouping in printing position and for simultaneously shifting all of the discs to shift each set die grouping from a first to a second character printing position comprises a spur gear mounted for reciprocation in the direction of the printing drum axis and for rotation to selectively engage each disc and to disengage from all discs. A locking bar, having a notch, is linked to the spur gear to reciprocate with it and position the notch in alignment with the disc engaged by the spur gear. The remainder of the bar projects into a groove in each of all other discs to hold them against rotation during the setting operation.

Abstract: A check printer and including a base having an upwardly facing check print surface thereon and a chassis disposed thereover, such chassis cooperating with the base to form a pathway leading from one side to the other of the check print surface. A plurality of printing wheels are mounted in side-by-side relationship from said chassis for disposition over the check print surface. An ink ribbon cartridge is mounted from the chassis and includes a flat frame overlying the print surface with ink ribbon rollers carried therefrom and disposed on opposite sides of such print surface. An actuating handle engages the chassis and is operable upon depression thereof to shift the chassis downwardly to engage the wheels with a check resting on the print surface to print the numbers selected on such individual wheels on such check.

Abstract: A compact flying printer having a continuously rotating print drum and ratchet wheel, a trigger lever positionable to be struck by a tooth of said ratchet wheel and a hammer lever driven by said trigger lever and provided with a print hammer at its end. The trigger lever is formed with a linear guide portion for regulating the motion thereof and an energy transmitting portion projected for transmitting energy from said ratchet wheel to said hammer lever.
