    摘要: A serial printer with a dot print head which prints print data produced in accordance with a page describing language. In this serial printer, it is judged whether or not character data is included in the print data and, if included, whether or not character data printable by the dot print head in a single scanning stroke exists in the character data previously judged, whereby the character data non-printable in a single scanning stroke of the head is printed similarly to graphic data included in the print data after being converted into image data, and the character data printable in a single scanning stroke of the head is printed independently of graphic data. Consequently, the character data can be printed without displacement of dots according to print ability of the dot print head and excellent print quality of the characters can be obtained.

    摘要: A paper feeding apparatus in a printer, wherein a sheet of paper placed on a rotary support member is fed by a predetermined distance through a corresponding angle of rotation of a drive motor which is energized by a drive circuit under control of a control device which applies a control signal to the drive circuit to give a predetermined angle of rotation to the drive motor and thereby effect a paper feeding cycle each time the control signal is applied. The control device includes control means for adapting the control signal so as to progressively increase the operating speed of the drive motor up to a predetermined level when the application of the control signal takes place more than a predetermined time interval after termination of the previous paper feeding cycle. When the application of the control signal takes place within the predetermined time interval, the control means adapts the control signal so as to cause the drive motor to operate at a constant speed equal to the predetermined level throughout the predetermined angle of rotation thereof.

    摘要: A printer enables discrimination of the kind of a printing medium and automatically controls whether the medium is to be thermally processed or not by the result of the discrimination, while enabling reversal of the execution or inexecution of the heating process if necessary. A control portion is able to discriminate the kind of a printing paper based on a signal output from a detector and changeover automatically, whether the printing paper is to be thermally processed or not, in moving a diverter from a first position to a second position by controlling a solenoid. A user can reverse the execution or inexecution of a heating process of a printed paper in operating the diverter by the operation of a reverse key provided in a control panel.

    摘要: Image data supplied from an external equipment is stored in an image data memory. The size of an outline region determined on the basis of the image data is compared with the size of the printable region of selected paper, stored in a size memory. If the outline region is larger, paper having a size larger than that of the selected paper is selected. Data of linear marks indicative of cut positions on the extension lines of virtual boundaries of the outline region is calculated on the basis of data of a pair of corners in the image data, to be synthesized with the image data supplied from the external equipment, for a print operation with respect to the print paper.

    摘要: A drive control system for controlling a drive motor in response to external command signals. The system comprises a first control arrangement for obtaining numerical values corresponding to amounts of successive intermittent operations of the drive motor responsive to respective external command signals, summing the obtained numerical values, and subtracting from a current sum of the numerical values a numerical value corresponding to a non-operation time period during which the drive motor is held at rest between the successive intermittent operations. The system further comprises a second control arrangement for inhibiting the operation of the drive motor responsive to the next command signal, for a length of time corresponding to the current sum after the drive motor has completed each of the intermittent operations, whereby the temperature of the drive motor is kept below an upper limit.

    摘要: A paper edge detecting device for a printing apparatus in which a paper margin of a print paper can be detected with high accuracy. A mark printing process is executed upon power-on of a printer, so that a carriage is displaced from an original position H0 to a position corresponding to a set pulse number H.sub.P and stopped at that position to print on the print paper a linear mark M aligned in a direction perpendicular to a displacement direction of the carriage. Thereafter, a mark detection process is executed, and the carriage is displaced from the original position H0 until the mark M is detected by the photosensor. Subsequently, a correction amount generating process is executed to calculate a correction value .alpha. on the basis of the set pulse number H.sub.P and the count value C.sub.P when the mark M is detected by the photosensor.
