Abstract
An ink jet recording apparatus comprises a recording head having a discharge port for discharging ink as a droplet, a head recovery device provided at a position opposed to the discharge port of the recording head, and a conveying belt driven for conveying a recording medium onto which recording is performed by discharging ink from the recording head. The conveying belt is located between the recording head and the head recovery device, which are located opposite to each other, and has an opening at a part thereof.
Claims24
An ink jet recording apparatus, comprising:
- a recording head having a discharge port for discharging ink as a droplet;
- head recovery means provided at a position opposite to said discharge port of said recording head, with said head recovery means including cap means for covering and receiving ink from said discharge port and suction means connected to said cap means for collecting ink from said discharge port to recover operation of said recording head in association with said cap means;
- and
- a conveying belt located between said recording head and said head recovery means and having an opening at a part thereof, with said conveying belt being driven to convey on an outer surface thereof a recording medium on which an image is formed by said recording head, wherein
- said opening is large enough to permit said recording head to contact said cap means through said opening, said head recovery means being disposed in an area surrounded by said conveying belt, and
- said recording head and said cap means are relatively movable only in directions opposed to each other whereby said cap means can cover said discharge port.
