The thermal head support device in the line printer

摘要

(57) Abstract Objective The thermal head support in the line printerNumber of articles of the device is decreased, cost decrease is assured. Constitution The left edge of leaf spring 15, with fixed screw 25 samaIt locks in ruhetsudo 16. It was provided in the intermediate section of leaf spring 15The head which can provide the U channel 23 of bearing 22, in the computer frameIt engages in spindle 14. Engagement section 24 of right hand edge of leaf spring 15, computerIt engages in the engagement channel 26 which is provided in frame 11. In thisThe ri, thermal head 16 with leaf spring 15 on platen 13 sideThe pushing it overpowers. As for the reaction force operation to leaf spring 15, the computer frameThe platen 13 which is home position, head spindle 14 and the engagement channel 26Containment leaf spring 15 by receiving in 3 dots. tsute, as for leaf spring 15, platen balance of 13 and head spindle 14 errorIn order to be able to absorb difference, thermal head 16 elasticity containmentFunctioning it does as the head containment board which it does. Therefore, hetsuIt is not necessary to provide the do containment board separately.
