Description

  The present invention relates to a cleaning member that cleans the surface of a linear encoder scale used in a recording apparatus that records an image on a recording medium by reciprocating a recording head in the main scanning direction, and the cleaning member is removable. The present invention relates to a recording apparatus.

  In a serial scan type recording apparatus, an image is recorded on a recording medium while a carriage on which a recording head is mounted moves in the main scanning direction with respect to the recording medium. In such a recording apparatus, various types of linear encoders have been used as detection means for detecting the position and speed of the carriage in the main scanning direction. Among them, optical encoders have excellent durability because the detector can detect without touching the encoder scale, are resistant to disturbances such as magnetic field changes, are inexpensive, and have high accuracy and high resolution. Since it is suitable for detection, it has become mainstream in high-performance recording devices.

  However, recently, along with the demand for higher performance of the apparatus, optical linear encoders are required to have higher precision and higher resolution, and the following drawbacks are regarded as problems.

  The inside of the recording apparatus is often the cause of contamination such as ink, paper dust, and lubricating oil, and if these adhere to the encoder scale surface, the transmitted light is reduced and the signal output of the linear encoder is reduced. In particular, in an ink jet recording apparatus, ink mist, in which a minute amount of ink is atomized when ink is ejected from the recording head, scatters in the air, so that the ink tends to adhere to the components inside the apparatus. The possibility of adhering to is also great.

  In addition, in optical linear encoders, a method of detecting with high resolution and high accuracy using a combination of optical phenomena such as reflection and refraction has appeared, compared to a method in which the number of light and dark slits is simply counted by a light receiving element. However, in such a method, if dirt such as water droplets that have transparency and change the curvature of the encoder scale surface adheres to the scale surface, the transmitted light from the scale deviates from the normal optical path. A signal is generated.

  The error due to the error signal described above, for example, affects the printing performance of a recording apparatus using a linear encoder. Needless to say, the error accumulation due to the error signal causes the carriage stop position to be out of order. Mechanical damage and runaway occur due to collisions with other parts of the carriage, leading to problems that lead to reduced reliability and durability.

  In order to solve such problems, there has been proposed a cleaning member that is removable from the recording apparatus and that removes dirt adhering to the encoder scale. For example, Patent Document 1 discloses a cleaning member 21 that removably engages with a guide member 4 and a guide shaft 5 that support a carriage provided in a recording apparatus and guide it in the main scanning direction, and that are in close contact with the front and back of the position scale 7. , 22 is described. The user can clean the position scale 7 by attaching the position scale cleaning tool 1 to the recording apparatus and moving the position scale cleaning tool 1 along the guide member 4 and the guide shaft 5 in parallel with the position scale 7. In addition, the number of each component shows the number of patent document 1, and is unrelated to the number in embodiment of this invention mentioned later mentioned later.

  However, in the configuration of the invention described in Patent Document 1, in order to clean the position scale 7, the user slides the position scale cleaning tool 1 along the guide member 4 and the guide shaft 5. As a result, the lubricant applied to the guide member 4 and the guide shaft 5 is wiped off in order to ensure the slidability of the carriage, and the guide member 4 and the guide shaft 5 may be damaged. As a result, there is a problem that the slidability of the carriage is lowered and the quality of the recorded image is lowered.
