摘要： In a serial impact printer, a printing head having an impact wire pin array of two arrangement lines is mounted on a carriage in such a way that the pin arrangement lines are inclined by an angle .theta. with respect to the virtual vertical direction. The respective wire pins in the array are driven at timings different delay time by delay time according to the inclination angle .theta.. The control circuit for determining the drive timings comprises a circuit for turning on the respective wire pins at the delay time intervals and a circuit for turning off the respective wire pins in sequence at the delay time intervals after a predetermined time has elapsed. It is desirable that the inclination angle .theta. satisfies the following formula:tan .theta..ltoreq.a/(2.multidot.b)where 2a denotes the pitch between two adjacent wire pins arranged along a single arrangement line of the array, and b denotes a distance between the two arrangement lines of the array.

摘要： A digital image forming apparatus is constructed to accurately detect period abnormality of a horizontal sync signal. In the apparatus, a sync signal generation portion outputs the horizontal sync signal by a received light signal from a light position detector. A sync signal abnormality monitor monitors whether a detected period of the sync signal is longer than a reference period, or it is normal. When the output signal of the sync signal is judged to be longer than the reference period, an abnormality detecting signal is supplied to a continuous turning-on portion. When the continuous turning-on portion receives the abnormality detecting signal, it issues an instruction to a synchronizing turning-on portion so that video data continues to be turned on, that is, turning-on signal is continuously outputted. Since a laser beam is continuously turned on by this instruction, the light position detector can certainly receive the laser beam. Accordingly, the period of the sync signal can be accurately detected and the cause of period abnormality can be specified.
摘要翻译：构造数字图像形成装置，以准确地检测水平同步信号的周期异常。在该装置中，同步信号产生部分通过来自光位置检测器的接收光信号输出水平同步信号。同步信号异常监视器监视同步信号的检测周期是否长于参考周期，或者是正常的。当同步信号的输出信号被判定为长于基准周期时，异常检测信号被提供给连续接通部分。当连续接通部分接收到异常检测信号时，它向同步开启部分发出指令，使得视频数据继续接通，即连续输出接通信号。由于通过该指令连续地接通激光束，所以光位置检测器肯定可以接收激光束。因此，可以精确地检测同步信号的周期，并且可以指定周期异常的原因。

摘要： A serial printer for printing on a recording medium which includes a platen, a carriage and a recording medium discharge section. The platen serves as a recording medium insert member and is rotated by a motor. A carriage shuttles in parallel with the platen and includes a recording head and a paper holder attached thereto. The sheet discharge section is arranged on a downstream side of the carriage and is provided for guiding the recording medium to a sheet discharge outlet. The printer further includes a carriage controller for moving the carriage towards the center of the recording medium and stopping the carriage proximate the center of the recording medium, while decelerating the carriage before the center of the recording medium, when the recording medium is forwarded for printing until the recording medium reaches a sheet discharge section from a predetermined position on the downstream side of the paper holder. A forward controller is provided for starting a recording medium forward operation for a single line of the recording medium in sync with the deceleration of the carriage. The carriage controller further moves the carriage proximate the center of the recording medium upon turning on the printer. The carriage controller also moves the carriage proximate the center of the recording medium when a print operation on the recording medium has ended.

摘要： A print controller apparatus and method thereof for controlling the movement of a printhead assembly including a carriage, printhead, and head pins. First and second moving times of the carriage moving from first and second predetermined distances and a difference between these moving times are determined. The carriage at a third predetermined distance is then determined based on the first and second moving times and the difference of the moving times. A basic timing signal corresponding to the current print mode is generated in accordance with the current moving time of the carriage. A correction value is then computed based on the current moving time of the carriage and from a preceding detected moving time which equals a predetermined time the printhead arrives at the printing paper. The basic timing signal is corrected using the correction value to thereby generate a print timing signal. In accordance with a speed signal being of an inverse proportion to the current moving speed of the carriage and with a preceding computed print timing signal, a drive signal in proportion to the speed signal causes the head pin to make contact with the printing paper for a corresponding amount of time.

摘要： A print head activation circuit for a wire dot printer includes a first switch and a second switch. A CPU produces a printing timing control signal. A first driving signal-generating circuit produces a first driving signal pulse having a pulse width T.sub.1 in response to the printing timing control signal. A delay circuit delays the first driving signal. A second driving signal-generating means produces a second driving signal pulse having a pulse width T.sub.2 in response to the leading edge of the delayed first driving signal. The first switching means is connected with a DC power supply. The first switching means is also connected with one terminal of each actuator coil of the print head. The second switching means is connected between a second terminal of the actuator coil and ground. The second driving signal-generating means is operated in response to the delayed first driving signal. The delay time .DELTA. T is set so that the first switching means is biased into conduction simultaneously with or earlier than the second switching means.
