摘要： PROBLEM TO BE SOLVED: To prevent the deviation of a nozzle recording position due to the thermal expansion of a recording head from occurring by using a simple recording head positioning mechanism and controlling the recording timing. SOLUTION: The left end of a recording head 103 is fixed in a freely rotatable manner by a pin 116 insetted in a groove part 115 formed ion the left side face 113 of a recording head fixing unit. On the right end of the recording head 103, a bearing 118 is buried to be fixed by a leaf spring 117 in such a manner that the bearing 118 is brought into contact under pressure with the right side face 114 of the recording head fixing unit. That is, the length of the recording head 103 varies in accordance with the temperature variations of the recording head 103, resulting in the shifting of the right end position of the recording head 103 in the paper conveying direction. Therefore, the recording timing is controlled so as to correct the deviation of a nozzle position according to the temperature variations to achieve the correct recording.

摘要： PROBLEM TO BE SOLVED: To prevent satellites which is a part of discharged ink from a recording head from adhering to a discharge opening face of the recording head because of influences by an electric field generated in a constitution designed to generate an electrostatic attraction force in an ink-jet recording apparatus in which the electrostatic attraction force is generated between a recording paper and a transfer belt thereby transferring the recording paper. SOLUTION: In addition to conductive patterns 202A and 202C for generating an electrostatic attraction force, a conductive pattern 202B kept approximately at the same potential as a recording head 119 is set inside a transfer belt 105, thereby preventing an electric field from being brought about between a discharge opening of the recording head 119 and a paper 101. Even when discharged liquid drops are separated to main drops 508 and satellites 507, no polarization is given rise to between the main drops and satellites and the satellites 507 are let to fly together with the main drops 508 to the paper 101.

摘要： PROBLEM TO BE SOLVED: To add a function for correcting an error by using the same parallel interface as before and provide an operation setting means for fast data transfer using a parallel port. SOLUTION: The parallel interface has a data bus for transferring print data, a Strobe signal indicating the effectiveness of the data bus, a Busy signal indicating that a printer is in use, and an Ack signal indicating data reception of the printer. Parity bits are represented by calculating even parity of respective bits of the data bus and controlling the width of the Strobe signal, thereby detecting an error of transmitted data. Further, the time from Strobe signal transmission to Ack transmission is shortened gradually by using training data and on the printer side, operation is set while a communication down such as data absence is detected as to the known training data.

摘要： PURPOSE:To obtain a memory controller capable of applying a high speed memory accessing method by supplying a conversion address from an address conversion means for changing the address bit weighting of a memory address correspondingly to processing data to a data memory. CONSTITUTION:The memory controller is provided with an address conversion part 4 for converting address data from a CPU or the like into a prescribed address signal as necessity. At the time of writing data in a data memory (a DRAM e.g.), write addresses from a host 20 are disconinuous addresses in each color, but practical write addresses in the data memory 3 are continuous addresses due to the converting operation of the conversion part 4. Thereby a high speed page mode or a nibble mode for the DRAM can be used for the control of data reading at the time of printing operation. Since the address conversion part 4 is prepared, the change of software can be made unnecessary.

摘要： PURPOSE:To set measured distance data easily and obtain an absolute position with high accuracy, by moving a sensor in an opposite direction to a scale, reading a measured distance code, processing the code and outputting data of the absolute position of the sensor. CONSTITUTION:A sensor 102 is set at a scale 101 to read a measured distance code. The signal is binarized and input to a correlation detector 103. Code searching is carried out until a generated code agrees. When an output from the detector 103 becomes a peak, a state of a shift register of a code generator 105 indicates a position of the sensor 102 on the scale 101. The content of the shift register at this time represents a current position of the sensor 102. The detector 103 sends a signal to the generator 105, whereby the content of the shift register is output. A look-up table 107 converts, when receiving the measured distance code from the shift register, the code to data of an absolute position and outputs the data. In this manner, the absolute position can be obtained by sequentially reading the measured distance data by the sensor 102.

摘要： PURPOSE:To make it possible to prevent contamination and offset caused by ink by providing a means, which can vary the standby time before the start of the back surface recording after the end of the front surface recording of a recording medium in double-surface recording in response to the kind of the recording medium. CONSTITUTION:When the recording for one page is finished, a recording medium 6 is discharged. When the recording operation is made for one-surface recording, the recording medium 6 is discharged on a paper tray 20. For the double-surface recording, the medium is set at a sucking position for back-surface recording. When the recording medium 6 is set at the sucking position for the back-surface recording, the recording is made to wait for the specified time before the start of the back-surface recording. For the standby time, the standby time corresponding to the preset kind of the recording medium 6 is set in the timer of a CPU30. The waiting is performed by driving a timer 35. After the elapse of the preset time of the timer, the recording medium 6 is sucked, the recording data are received from a host computer by the same way as the operation in front-surface recording and the recording is performed for every one line. After the recording of one page is finished, the recording medium 6 is discharged, and the front-surface recording and the back-surface recording are completed.
