Work working method and apparatus, cassette, and unit for printing apparatus

A working method of performing working of a work, comprising the steps of:

• controlling a cleanliness with respect to dust particles independently in each work chamber, a plurality of work chambers being arrayed consecutively corresponding to work steps for the work,
• transferring the work to the respective work chambers, and
• performing the working in each of the work chambers in which a cleanliness is maintained below a predetermined cleanliness corresponding to a type of working of the work.

A working apparatus for performing working of a work, comprising

• a work chamber in which the working is performed,
• said work chamber having a cleanliness atmosphere from which dust particles have been removed by a gas flow, and the cleanliness atmosphere in which a cleanliness is maintained hierarchically.

A working apparatus for performing working of a work, wherein

• a plurality of work chambers corresponding to work steps for the work are arranged, and
• each of said work chambers includes means for independently maintaining a cleanliness, means for transferring the work to each work chamber, and process means for performing a process corresponding to each step in each of said work chambers.

A method of working a unit for a printing apparatus which discharges a liquid, comprising the steps of:

• controlling a cleanliness with respect to dust particles in a work chamber in which the work is worked hierarchically in the work chamber, and
• performing the working of a work forming the unit at a position at which the cleanliness is high so as to prevent dust particles from adhering to the unit.

A unit for a printing apparatus which has a liquid discharging nozzle mounted on a substrate, wherein

• said unit is worked by a working apparatus having a plurality of work chambers in which a predetermined cleanliness is maintained, and a cassette which can be coupled to the work chamber and supplies the nozzle, and the substrate and the nozzle are worked in an atmosphere with a predetermined cleanliness.

A working method for a unit for a printing apparatus which prints on a carrier by discharging a liquid, comprising the steps of:

• controlling a cleanliness of a plurality of independent work chambers corresponding to work steps for the unit which has a nozzle mounted on a substrate, and
• performing the working of the unit through the plurality of independent work chambers which are controlled to have a cleanliness corresponding to the work step.

A working method of performing working of a work, wherein

• dividing a work atmosphere for the work into a plurality of independent work regions,
• maintaining the divided regions at a predetermined cleanliness, and
• performing the working of the work by transferring the work from the first independent work region to the second independent work region by first transfer means which reciprocally moves between the first and second work regions to receive and transfer the work.
