Abstract

PURPOSE:To attain to enhance the quality of recording by preventing the vibration of a recording head, by providing a vibration-proof material, which absorbs the vibration generated by the meshing of the rack teeth of the belt connected to a carriage with the groove of a pulley transmitting driving force to said rack teeth, on the carriage. CONSTITUTION:At the time of recording, a timing belt 4 is driven by rotationally driving a pulley, which has not only the timing belt 4 wound therearound but also the groove meshed with rack teeth 4a, by a motor and a carriage 2 is pulled by the timing belt 4 to allow a carriage 2 to run on slide shafts 1, 1'. With the running said carriage 2, an ink jet head 6 is driven corresponding to recording data by the driving signal applied through a flat cable 9 and ink liquid droplets are emitted from the orifices arranged to the front surface of said head 6 to perform recording. In this case, vibration is generated in the timing belt 4 by the meshing of the rack teeth 4a of the timing belt 4 and the groove of the pulley but absorbed by vibration-proof materials 3, 3', 5, 5' and, because the transmission of vibration to the ink jet head 6 is prevented, high grade recording can be performed.

The method using the timing belt 23 shown in FIG. 4 has little belt elongation, is easy to assemble, and can be constructed at low cost, so this method is often used. However, in this method, the rack teeth of the timing belt 23 and the pulley 21
, 22 come into contact (interference) when the timing belt 23 enters and exits the mesh, causing vibrations in the timing belt 23. Particularly in recent years, there has been a trend to make recording heads smaller and lighter and to increase the moving speed of the carriage to perform high-speed recording. However, the more this is done, the greater the vibration described in item 1 becomes, which is transmitted to the recording head. As a result, a deviation occurs in the recording position, and the recording quality deteriorates. For example, by driving the recording head at very short predetermined pitches in the main scanning direction,
When attempting to record a line, variations occur in the pitch in the main scanning direction indicated by arrow F in the recording performed as shown in FIG. Further, variations in recording positions also occur in the sub-scanning direction.
