Latest Patents
One of his latest patents is for a printer having a continuous paper/cut paper changeover apparatus. This invention provides an apparatus capable of automatically changing over between continuous paper and cut paper. It allows for manual changeover even if an actuator is locked due to an accidental paper jam, thus facilitating processing. The design includes a platen gear associated with a tractor drive gear via a clutch gear, which connects or disconnects both gears upon oscillation of a clutch lever. The clutch lever is moved by a changeover lever, driven by a stepping motor, allowing for manual movement under normal conditions.
Another significant patent is for a dot matrix printer featuring a print head position adjusting mechanism. In dot impact printers, thermal expansion or contraction of the platen or print head can alter the gap between the print head and the print paper. To maintain a proper gap, a temperature sensor is included to sense the temperature of the platen or print head. The gap is adjusted based on the sensed temperature, ensuring consistent printing quality.
