<p>PURPOSE:To obtain a small sized recorder of simple structure by a method wherein a high speed printing is effected by utilizing a reversing position of first carriage under a continuous printing condition while utilizing the same position of second carriage under a waiting condition. CONSTITUTION:A linear motor is constituted with a permanent magnet PM, a magnetic plate Y1 and a magnetic sliding shaft Y2, and a carriage CA is driven by feeding an electric current to a coil bobbin CB in which the shaft Y2 is slidable. A scale disc OS of a non-magnetic material is bended at both ends thereof toward the plate Y1 and fixed to an end portion Y1T horizontally together with the shaft Y2, thus, is secured to the shaft Y2. A slit scale detecting means consisting of the coil bobbin CB, an ink jet nozzle NP, a photo diode LE fixed by bonding agents EP1, EP2, a photo transistor PT and a print plate PC is secured to the carriage CA. Terminals of a piezo PZ being a driving source of the ink jet nozzle NP, the photo diode LE and the photo transistor PT are connectted to the print plate PC, while all signal wires of these parts are connected to one end portion FL1 of a flexible cable Fl at an terminal portion PC1 of the print plate PC, and the other end FL2 controls a driving of the carriage CA and the piezo PZ for the ink jet nozzle NP through a connector CN.</p> |
