Speed controlled printer

A printer for printing on a recording paper, comprising:

• printing head means, said printing head means being mounted for incremental translation relative to said paper for printing a line of characters thereon;
• means for translating said printing head means for said printing;
• speed control means cooperating with said printing head means, said speed control means controlling the speed of said incremental translation of said printing head means, said speed control means including teeth means and ankle means having at least two ankle pawls for alternate engagement with said teeth means, said incremental movement of said printing head means being caused by said alternate engagement of said ankle pawls with said teeth;
• detection means mounted on said printing head means, said detection means providing a signal at each increment of movement of said printing head means for printing, said signals synchronizing actuation of said printing means with each incremental position of said printing head means, said detection means including a lever on and moving with said ankle means, and a detector, said detector detecting a pivoting motion of said lever and producing said signals each corresponding to an incremental movement;
• printing means mounted on said printing head means and moving therewith, said printing means printing on said paper when said printing head means is moved for printing.
