Title: Platen gap adjustment mechanism, platen gap adjustment method and recording device
Inventor: AKAHA CHIKAKO
IPC: B41J25/308
Filed: 2002-12-24
Abstract: <P>PROBLEM TO BE SOLVED: To provide a platen gap adjustment mechanism which can adjust a platen gap to suppress a recording density variation, and to provide a platen gap adjustment method and a recording device.  <P>SOLUTION: The recording device for recording images to a sheet supplied between a recording head and a platen by striking a recording wire hammered out of the recording head via an ink ribbon has a platen gap adjustment means for adjusting the platen gap between the recording head and a platen face. The platen gap adjustment means preliminarily measures a distance between the recording head and the platen by a predetermined timing, and stores the measured value. When the platen gap is to be adjusted, a distance between the recording head and a sheet face is measured, and a thickness of the sheet is calculated by subtracting the measured value from the stored distance between the recording head and the platen face. The platen gap is adjusted on the basis of the thickness of the sheet.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
