Abstract

Zur Einstellung des Druckspaltes und gegebenenfalls auch der Anschlagstärke wird bei einem Matrixdrucker, insbes. einem Nadeldrucker, dem Druckkopfhalter (1) ein Tastfinger (10) zugeordnet, der das Lagerspiel zwischen dem Halter (1) des Druckkopfes (2) und seiner Führungswelle (8) erfaßt. Wird beim Anlegen des Druckkopfes (2) gegen das Druckwiderlager (6) oder einen Aufzeichnungsträger (5), der Druckkopfhalter (1) gegenüber der Führungswelle (8) angehoben, so wird durch diese geringe Bewegung über den Tastfinger (10) ein elektrisches Signal ausgelöst. Damit wird die Lage des Druckkopfes (2) bzw. seines Stellantriebes (7) erfaßt. und der Stellantrieb (7) entsprechend der gewünschten Einstellung des Druckkopfes (2) gesteuert.

Figure 00000001
In order to adjust the printing gap and, if necessary, also the stroke strength, a touch finger (10) is assigned to the print head holder (1) in a matrix printer, in particular a dot matrix printer, which detects the bearing play between the holder (1) of the print head (2) and its guide shaft (8 ) detected. If the printhead holder (1) is raised in relation to the guide shaft (8) when the printhead (2) is placed against the platen (6) or a record carrier (5), an electrical signal is triggered by this slight movement via the touch finger (10) . The position of the print head (2) or its actuator (7) is thus detected. and the actuator (7) is controlled according to the desired setting of the print head (2).
