Description

  The present invention relates to an ink jet recording apparatus that performs recording by discharging ink from a recording head to a recording medium.

  In an ink jet recording apparatus that forms an image on a recording medium by ejecting ink droplets from a recording head, it is generally performed to cover with a cap for the purpose of protecting the ink ejection portion of the recording head during non-recording. The functions required for the cap are protection of the ejection port of the recording head and prevention of evaporation from the inside of the cap to the atmosphere. That is, the fine discharge port portion of the recording head is protected from physical damage, and ink thickening due to evaporation of the ink solvent from the discharge port and clogging of the discharge port due to the ink thickening are prevented. That is.

  Therefore, it is configured to shield the inside of the cap from the atmosphere by bringing the peripheral rib of the cap into contact with the periphery of the discharge port of the recording head, and using the flexibility of the cap material to closely contact the peripheral rib. Yes. As the material of the cap material, a flexible material such as rubber is used. In addition, since the cap comes into contact with a position close to the ejection port, the cap material needs to have a property that does not cause a chemical reaction with the color material or the solvent in the ink. Furthermore, it is desirable that the amount of ink solvent that evaporates through the cap is as small as possible. From such a viewpoint, for example, a flexible material such as chlorinated butyl rubber, butyl rubber, and elastomer is selected as the cap material. In addition, there are recording heads that are interchangeably mounted on the carriage that performs reciprocating scanning, and those that are fixed to the main body of the recording head, and are assembled when the operator unpacks / installs the recording apparatus. Or those already installed at the time of shipment from the factory.

  When the cap is made of chlorinated butyl rubber, the operation force necessary to release the adhesive state between the recording head and the cap and peel it off is as follows. That is, the operating force reaches several tens of N (several kgf) at the time of arrival after passing through a physical distribution storage state from factory shipment, and a considerable force is required to separate (peel) the cap from the recording head. . On the other hand, the operating force during normal use is 0.5 N to 2 N (50 gf to 200 gf), and there is a large gap from the operating force at the time of arrival. As for the number of caps, the number of ink colors to be mounted for image formation has been increasing in recent years, and the number of caps has increased accordingly since the number of recording heads has increased according to the number of ink colors. Tend to. For this reason, there is a tendency that the operating force for peeling the cap that is in close contact with the recording head also increases. This is not limited to the case where the cap material is chlorine butyl rubber, and the same applies when the cap is made of other flexible materials.

For this reason, the cap should be used when the recording device is shipped from the factory with the recording head installed, or when the recording device is used less frequently after the recording head is installed by the operator. It is necessary to select a drive source such as a motor assuming a maximum load state in which an operation force to be peeled off from the recording head is large. Furthermore, it has been studied to add another release mechanism for forcibly releasing the close contact between the recording head and the cap, and the packaging material to be removed when the apparatus main body is installed in a usable state. It has also been studied to release the close-contact state of the cap by using.

  However, in the above-described prior art, if a drive source such as a motor is configured assuming a maximum load when a cap that has been in close contact for a long time is peeled off, there is an inconvenience that the apparatus is increased in size and cost. Moreover, in order to guarantee the operation at a high load as described above, it is necessary to increase the strength of the parts of the transmission mechanism from the drive source. There is a risk of increasing the size and cost. Furthermore, in the method of installing a dedicated release means for releasing the cap and letting the operator operate it, there is a risk that if the release operation is forgotten, it may temporarily become inoperable when installing the recording device. is there. In addition, in the case of the release means that also uses the packaging material, it is necessary to process the packaging material after the recording apparatus is installed, resulting in an inconvenience that the environmental load increases.

  The present invention has been made in view of such a technical problem, and an object of the present invention is to provide a simple drive source without requiring a new drive source in the process of installing the recording apparatus in a usable state by the operator. Another object of the present invention is to provide an ink jet recording apparatus that can release the contact between the recording head and the cap without being aware of the releasing operation by extending the installation operation with an inexpensive configuration without causing an environmental load.
