Claims

[Claims for Utility Model Registration] 1. A plurality of print sheets of arbitrary thickness are mounted in parallel at intervals on a platen, and printing is sequentially performed on each of the print sheets while sliding the print head along the longitudinal direction of the platen. A serial printer that carries out the following steps: a carriage on which the print head is placed; a non-contact detection device that is installed on the print head or the carriage and is capable of identifying the presence or absence of each print paper; and a thickness of each print paper. a position adjustment means that automatically adjusts the gap between the print head and the print paper according to the position, and control that starts the position adjustment means for each print paper by an initial signal from the detection device that notifies the presence of each print paper. A serial printer characterized by comprising a device and the following. 2. The serial printer according to claim 1, wherein the platen or the paper guide for guiding the printing paper is dark-colored, and a reflective sensor is used as the detection device.
