Abstract

1422812 Recording apparatus CAMILLE BAUER MESSINSTRUMENTE AG 27 Sept 1973 [6 Oct 1972] 45348/73 Heading G1J [Also in Division B6] A chart recorder comprises a number of printing elements 5 Fig. 1, or 27a, b, Fig. 2, attached to a movable transport means 1 or 23, e.g. a continuous belt or chain, to be moved linearly across a record medium 7 or 25, a permanent magnet 2 or 26a, b attached to each printing element, and fixed electromagnet 3, 4 or 21, 22 spaced from but aligned with the permanent magnets, each permanent magnet being of opposite polarity to the next adjacent permanent magnet(s), and means for selectively exciting the electromagnet(s) with a given polarity to deflect one or more of the permanent magnets towards the record medium to cause the associated printing element or elements to print thereon. The support arms 8 of the printing elements 5 are of flexible springy material and carry the permanent magnets 2 part-way along their length. In Fig. 2, one electromagnet 21 is associated with permanent magnets 26a of one set of printing elements 27a, and a second electromagnet 22, independently excited is associated with the permanent magnets 26b of a second set of printing elements 27b. One set of printing elements may print dots, crosses, or other plotting symbols, and the other set may print alpha-numeric characters to identify the traces, or to print time or other reference markings at the side of the chart, or to print a coded or non-coded message. The printing elements 5 strike the chart 7 through an ink ribbon 6, Fig. 1, or they may be caused to contact an ink ribbon away from the chart by an auxiliary electromagnet.
