摘要： Bit data of a received video signal is partially converted into a first signal representing a data sequence corresponding to the resolution of an LED head. The remaining bit data of the received video signal, which are not converted into the first signal are converted into a second signal representing another data sequence corresponding to the resolution of an LED head. The LED head includes a resolution conversion circuit which converts the video data into the first signal and the second signal. The signals are stored in a shift register having a plurality of line buffers. The first signal is printed on a basic raster line and the second signal is printed on an additional raster line. An LED head drive energy with which basic raster lines are printed and another LED head drive energy with which additional raster lines are printed are set independently of each other.

摘要： A multivoltage power supply which can output a plurality of high voltages in parallel. The voltage values of the respective outputs are feedback to an A/D converter. Each feedback signal is converted to a digital signal and the difference between the digital signal and a corresponding predetermined output voltage is then calculated in the form of a digital value. This digital value is inputted to a corresponding auto-reload timer, whereby a pulse signal having a pulse width corresponding to the digital value is output at a predetermined frequency.

摘要： In a printer that includes a carriage section having a print head with a plurality of drive coils provided therein, and a control unit having a power supply circuit supplies drive power to the print head, and a cable having conductors for connecting the control unit and the carriage section, a drive power supply node and discharge node in the carriage section are connected to an output terminal of the power supply circuit in the control unit via the cable. Drive power for the plurality of drive coils is supplied from the terminal of the power supply circuit through the cable and the drive power node, and magnetic energy accumulated in the drive coils is discharged through the discharge node and through the cable to the output terminal of the power supply circuit. Printer protection is achieved by detecting, in the carriage section, whether the discharge node is satisfactorily connected with the terminal of the power supply circuit. This is determined in accordance with the magnitude of the voltage applied to the discharge line. The printing operation is prevented if an unsatisfactory connection is detected.

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： The present invention relates to a method of leading a moving body, such as a print head carrier of a printer of the like, which is driven by a direct current brushless motor, to a starting position. The direct current brushless motor, which forms part of the present invention, includes a stator including a plurality of armature coils secured on a stator yoke through a substrate, a disk-like magnet having N and S poles arranged alternately in the circumferential direction, the magnet being arranged to confront the armature coils, and a rotatable rotor provided with a speed-detecting slit arranged outside the magnet. Rotating power is obtained by applying an electric current corresponding to the magnetic pole of the magnet to each armature coil. A speed detector detects the speed-detecting slit and puts out a frequency pulse voltage proportional to the speed and a counter counts the output pulses from the speed detector to count out the timing to change the excitation phases to the armature coils so as to continuously rotate the rotor. The method of the present invention is characterized in that a stopper to stop the motion of the moving body is arranged so that at a position of a maximum torque of the direct current brushless motor or a predetermined position close to the maximum torque position, the moving body impinges against the stopper to stop rotation of the rotor, the count number in the counter is reset and the motor is then driven in the reverse direction to lead and locate the moving body at a starting position.

摘要： Bit data of a received video signal is partially converted into a first signal representing a data sequence corresponding to the resolution of an LED head. The first signal is transmitted to the LED head in the form of a real printing data signal that is to be printed on a basic raster line in synchronism with a line timing signal. The remaining bit data of the received video signal, which are not converted into the first signal, are converted into a second signal representing another data sequence, and then stored in a line buffer. The second signal stored in the line buffer is transmitted to the LED head in the form of a real printing data signal that is to be printed on an additional raster line in synchronism with an additional line timing signal. The LED head drive energy with which the basic raster lines are printed and another LED head drive energy with which the additional raster lines are printed are set independently of each other. The LED head may be provided with such a resolution function.
