Abstract

A liquid droplet ejecting apparatus of the present invention includes a cleaning unit, a regular flushing unit, capping unit, and an ejection-amount measuring unit as droplet ejecting head maintenance units used for function maintenance, function recovery, adjustment, or inspection of a liquid ejecting head. The droplet ejecting head maintenance units are arranged in a group in a movable platen as a maintenance-unit installing section. The movable platen is supported by an accessory stand physically separated from a main body.

Claims (14)

1. A liquid droplet ejecting apparatus comprising:

a work mounting unit on which a work is mounted;

a droplet ejecting head for ejecting a functional liquid to the work;

a droplet ejecting head maintenance unit; and

a maintenance-unit moving mechanism,

wherein the maintenance-unit moving mechanism moves the droplet ejecting head maintenance unit with respect to the droplet ejecting head, and

wherein the droplet ejecting head maintenance unit comprises:

a flushing unit for receiving an ejected droplet, the flushing unit including an absorbent material; and

an ejection-amount measuring unit for measuring an ejected droplet amount.

2. The liquid droplet ejecting apparatus according to claim 1 , further comprising a relative movement mechanism for moving the work mounting unit with respect to the droplet ejecting head, wherein the work mounting unit is movable in the same direction with the droplet ejecting head maintenance unit.

3. The liquid droplet ejecting apparatus according to claim 1 , wherein the droplet ejecting head maintenance unit comprises a detecting unit for inspecting an ejected droplet.

4. The liquid droplet ejecting apparatus according to claim 1 , wherein the droplets are ejected during ejection periods and waiting periods between ejection periods, the flushing unit receiving ejected droplets during the waiting periods.

5. The liquid droplet ejecting apparatus according to claim 4 , wherein the flushing unit includes liquid receivers for receiving the ejected droplets during the waiting periods.

6. The liquid droplet ejecting apparatus according to claim 5 , wherein the liquid receivers each include the absorbent material.
