摘要： A printer includes a controller for providing a sequence control for the printer in its entirety in response to a control signal and a video signal from another controller. A printer head is adapted for latching and printing a printing data signal transmitted from the controller. Print data arithmetic and logic circuitry provides a logical operation processing for video data signals, counting video clock signals transmitted from the controller, and includes storage for storing the video data signals transmitted from the controller, a selector responsive to reference line timing signals for selectively alternately outputting the video data signals, an additional line signal generator for generating from video signals received from the controller, a video data signal representing an additional line destined for between reference lines during an interval of timing, and logical operation circuitry for performing a logical operation for the video data signals read out from the storage and supplying to the printer head the video data signals subjected to the logical operation in the form of the printing data signal.

摘要： A printing head drive circuit of a printer is mounted on the side of a carriage having a printing head attached thereto for a allowing said carriage to act as a heat sink. Hereby, no particular cooling means (heat sink, cooling fan and the like) is required for printing head drive elements. In addition, a controller and heat generating parts can be completely separated. Thus, it can be anticipated to reduce the number of parts and the cost required for assembling the whole structure as well as to improve reliability of the printing head drive circuit.

摘要： A switching regulator includes a high frequency transformer having a primary and secondary and tertiary windings. It also has a switching element and shunt regulator and photo coupler and control circuit and these elements are arranged for controlling the on-period and the on-time of the switching element so as to increase the on-period as well as the on-time when the load is heavy. The switching losses caused by the limit of the capability of the switching element as a result of an increase in the on-period upon the load becoming light are prevented while the switching frequency is prevented from becoming an audio frequency upon the load becoming heavy. Thus, a high efficiency switching regulator with a wide range of equal load capacities may be constructed.

摘要： A printer includes a first paper feed passage extending from the rear of a platen to a printing position through the lower part of the platen, and a second paper feed passage extending from substantially just under the printing position to the printing position. A first pinch roller is disposed on the way to the first paper feed passage for pressing a first paper against the platen. The first paper is fed by rotating the platen. A second pinch roller is disposed on the way to the second paper feed passage for pressing the second paper against the platen. Rotation of the platen causes the second paper to be fed. In addition, a paper insertion device includes a flat part for placing a paper thereon and a slit for converting the advance direction of a paper from horizontal to vertical. With the second paper placed on the flat part and inserted into the printer, the paper is directed upwardly by a curved surface defining the slit and is allowed to enter the second paper feed passage with ease for further advance.

摘要： Disclosed is a serial printer comprising a carriage loaded with a printing head and moved in the horizontal direction, wherein a motor is contained in the carriage, a pinion is attached to a rotor shaft of the motor, a rack engaged with this pinion is attached onto a guide rail for movably supporting the carriage and the carriage loaded with the printing head is moved along the rack by rotating the pinion engaged with the rack by rotation of the motor.In this serial printer, the power loss of the motor due to the presence of an intermediate power transmitting member indispensable for the conventional printer, such as a wire rope, a toothed belt or a screw shaft, can be eliminated, and occurrence of troubles due to stretching or deformation of this intermediate power transmitting member is prevented. Accordingly, the capacity of moving and positioning the printing head is increased. Furthermore, since the carriage is of the self-running type, it is possible to adopt an embodiment in which at least two carriages are mounted on one printer and they are independently moved to effect the delivery operation. Accordingly, the printing speed can be increased and multi-color printing can be performed.
