    摘要： A printer having a printing mechanism for placing printed matter on a substrate, the printing mechanism including character printing elements and an electrically driven hammer unit which is connected to receive an actuating current and is operative for causing the printing elements to print characters on the substrate by impacting against the elements with an impact force dependent on the magnitude of the actuating current, the printer being further provided with: a substrate thickness monitoring device mounted in the printer for monitoring the thickness of a substrate disposed to be printed upon by the mechanism and for producing an electrical output signal indicative of the substrate thickness within a predetermined amount of time; and an actuating current control circuit connected to receive the output signal from the monitoring device and to control the actuating current in a manner to reduce the impact force when the substrate thickness is less than a selected value.

    摘要： A printing apparatus having two character generators, one which generates characters common to a plurality of countries, comprises a keyboard for entering character codes, a first character generator for producing certain character patterns representing certain character codes common to a plurality of countries, and a second character generator for producing other character patterns representing other character codes. A buffer stores the character codes entered by a keyboard and a selection signal generator generates a selection signal in dependence on each character code stored in the buffer. The selection signal indicates that the second character generator is to be utilized to produce the other character patterns represented by the other character codes. A processor controls the operation sequence ofthe apparatus. The buffer is responsive in the absence of generation of the selection signal by the generator to access the first character generator to produce one of the certain character patterns and the processor is responsive to generation of a selection signal by the generator to access the second character generator to produce one of the other character patterns.

    摘要： An impact printer utilizes a single print hammer which is loaded with a selected type chip transferred from a rotatable carousel cartridge containing plural type chips. A single solenoid motor is energized to effect chip transfer, the loading of a spring to effect subsequent return of the chip to the cartridge, and the loading of an energy storage spring utilized to power the print hammer toward a platen. Completion of the chip transfer to the print hammer releases the print hammer to be powered by the storage spring until the solenoid motor is de-energized. The solenoid armature provides a reaction force to the storage spring only during solenoid energization. The duration of solenoid energization thus controls the impact force of the print hammer and is varied in accordance with the character area of the selected type chip and with the desired print density. An interlock latch prevents return motion of the type chip positioning and transfer mechanism during printing and during return motion of the print hammer. A restraining latch restrains the print hammer in its chip receiving position until the chip transfer to the print hammer is completed. The latching member of this latch is resiliently urged to restore the type chip to the cartridge upon return of the print hammer to its chip receiving position. An additional mechanism insures clearance of the latch member from the cartridge upon return of the type chip thereto.
