Abstract: Tête d'impression. Les électrodes E1, E2, E3,. En sont disposées selon une droite ascendante par rapport au sens de déplacement de la tête, et elles sont espacées entre elles de manière telle que l'incrément qui les sépare augmente linéairement. Si l'on désigne par E'1, E'2, E'3,. E'n, des électrodes fictives, régulièrement espacées, E1 coïncidant avec E'1, E2 s'écarte de E'2 de DELTA x, E3 de E'3 de 2 DELTA x, etc. Imprimantes.

Abstract: In a high-resolution electroerosion print head, the relatively fine electrodes are guided in thin glass tubes, the glass tubes being embedded in the body of the print head or the like. Feed rolls are provided for advancing the electrodes, such feed rolls being paired and each pair including a first, hard roll provided with grooves for guiding the electrodes, and as second roll of a relatively softer material. The hard material can be an acrylonitrile-butadiene-styrene-copolymer, and softer material, a polyurethane.

Abstract: RECORD MARKING APPARATUS Control circuit for printing head of a metal paper printer with electrodes arranged on a slope, said electrodes being staggered in horizontal projection by the D-fold of their electrode width. The matrix-like structurized character consisting of individual image elements is stored in a main storage. This character information is read out column-by-column and written into predetermined locations of a read/ write buffer storage. Such a write phase is followed by a read-out phase of predetermined locations of the storage for the direct addressing of the electrodes of the writing head. Write and read phases are alternating. For determining the address of the storage locations during the write and read phases two counters are used in particular in connection with a multiplier and an adder, as well as a register for storing the D-value.

Abstract: The disclosure relates to a print buffer, and its addressing, which is used to edit print data for a multiple electrode print head of a metal paper printer wherein the electrodes of the print head are arranged on a slope. The information to be printed is initially stored in the form of a matrix. In accordance with the arrangement of the electrodes in the print head, this information is edited in the print buffer and editing is effected in such a manner that the desired print image is obtained when the print buffer is read column by column. The information stored in a register in, for example, two groups of four bits each, is read in parallel and edited in the buffer. The information of the upper group is stored in buffer 1 and the information of the lower group in buffer 2. Each column address of the buffers comprises four bit positions. The information is written at different points of the four possible bit positions of different column addresses. One buffer line is associated with each electrode of the print head and the information is written into the buffers taking into account the horizontal stagger of the print head electrodes. The buffers are addressed by a suitable logic as a function of the number of electrodes and their mutual spacing. GE 979 044
