摘要： According to a method of adjusting a head gap, a wire dot head is set to a predetermined position of a reference head gap; a printing pattern for detecting printing time is printed by a plurality of pins; reference printing times of respective pins are detected. Next, a test printing is performed with test printing dots previously selected from printing data, and printing time of the test printing is detected. Then, the thickness of the printing media is calculated based on the reference printing time and the printing time of the test printing. At that time, a rule of thumb in which the difference of the printing time corresponds to the difference of the head gap, is used. Then, a shift amount of the wire dot head is calculated for setting the head gap to an optimum value according to the thickness of the printing media, and gap shifting mechanism shifts the wire dot head by the shift amount. This leads to highly accurate detection of the head gap and improves printing quality thereof.

摘要： An IC card connecting mechanism for connecting an IC card (30) having a terminal array(32), and a connector (46) for connecting the IC card (30) to an external equipment. The IC card connecting mechanism comprises the frame (35) of the IC card (30), having a peripheral rim (38) provided with recesses (39) respectively at the opposite ends of the front portion thereof, the terminal protecting member (41) of the IC card (30), having a terminal protecting part (41a) for protectively covering the terminal array (32), and legs (41b) extending from the opposite longitudinal sides of the terminal protecting part (41a) and held at the respective free ends thereof on the frame (35) of the IC card (30), the body (55) of the connector (46) having guide legs (53) for guiding the IC card (30) in inserting the IC card (30) in the connector (46), and lifting means (50) provided in the body (55) of the connector (46) so as to enter the recesses (39) of the frame (35) to lift up the terminal protecting part (41a) of the terminal protecting member (41) when the IC card (30) is inserted in the connector (46). Thus, the terminal protecting part (41a) of the terminal protecting member (41) is lifted up automatically to expose the terminal array (32) for electrical connection with the conductors (51, 52) of the connector (46) when the IC card (30) is inserted in the connector (46).

摘要： A driving apparatus for controlling the drive of a direct current (DC) brushless motor (100) including a stator having a plurality of armature coils which are provided on a generally circular stator yoke, and a rotatable rotor in which a disk-like magnet having N and S poles arranged alternately in a circumferential direction is provided on a generally circular rotor yoke to face the armature coils, includes a speed sensor (102a, 102b) for producing outputs responsive to a rotation speed of the rotor, a counter (116) for counting the pulses which are produced by the speed sensors, a control circuit (110, 104) responsive to the speed sensors and counter for controlling the current, which is applied to the armature coils, to apply currents to the armature coils in a predetermined sequence to thereby rotate the rotor, and a mechanism for cancelling a load acting on the rotor. The control circuit, at a start-up of the motor, switches the current applied to the armature coils to excite the armature coils in several different phases to thereby locate the rotor at a starting angular position, in the event when the rotor is located at the starting angular position, cancels a load acting on the rotor, at least before a last one of the phases is excited, subsequently controls rotation drive by counting output pulses of the speed sensor to determine an angular position of the rotor, and controls a rotation direction of the rotor on the basis of output pulses of the speed sensor and on a resuling count of the pulses. Also provided is a driving method for a DC brushless motor for effecting such a control.

摘要： In a dot print head of an impact type moved in a direction of spacing movement relative to a printing medium, and having a plurality of printing elements each having a printing wire arranged substantially in an elongated circle centered at a line parallel with the direction in which the printing elements are driven, and which is provided with a wire guide having guide elements for the respective printing wires for guiding tips of the printing wires to predetermined positions on said printing medium, the guide elements are divided into at least four rows each extending in the direction orthogonal to said direction of the spacing movement and orthogonal to the direction in which the printing wires extend, and distances between said rows are multiples of 1/240 inches. Each of the printing elements is driven for printing either at a reference timing which occurs once a standard printing cycle having a standard period, at a timing 1/4 of the standard period past said reference timing, at a timing half the standard period past said reference timing, or at a timing 3/4 of the standard period past said reference timing.

摘要： Bit data of the received video signal is partially converted into a first signal representing a data sequence corresponding to a resolution of an LED head (19 in FIG. 1). The first signal is transmitted to the LED head in the form of a real printing data signal 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 of another data sequence, and then stored in a line buffer (55 in FIG. 7). The second signal stored in the line buffer is in turn transmitted to the LED head in the form of a real printing data signal to be printed on the additional raster line in synchronism with an additional line timing signal. LED head drive energy with which the 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.
