Abstract
A printer comprising printing type belts 16 and 16' having printing types 16b and 16b' as well as indicating types 16d and 16d', and setting wheels 7 and 7' for turning the printing type belts, and configured to limit the turnings of the printing type belts for preventing the indicating types from being fouled, and to allow the setting wheels to rotate idly for preventing breakage of the printer itself after the printing type belts have reached rotation-limited positions. The rotation-limited position is determined by a pair of convexities 16e and 16f or 16e' and 16f' formed on each of the printing type belts and edges 4a and 5a or 4a' and 5a' of display window frames 4 and 5 or 4' and 5'. The setting wheels are allowed to rotate idly by recesses which are formed in the printing type belts so as to be engaged with teeth 7b and 7b' of the setting wheels, and configured so as to have slanted surfaces 16h and 16h' rising from sides near the convexities toward sides far from the convexities.
