INK-JET RECORDING APPARATUS

摘要

A recording apparatus includes a recording head, a sub tank, an ink tank containing ink supplied to the sub tank, a detector that detects an amount of ink contained in the sub tank, a variable volume member provided between the recording head and the sub tank and having variable inner volume, and a controller that repeatedly performs first and second operations, thereby supplying ink from the ink tank to the sub tank. In the first operation, the member is caused to switch from a first state to a second state, while in the second operation, the member is caused to switch from the second state to the first state.

1. An ink-jet recording apparatus, comprising:
a recording head configured to eject ink; a sub tank containing ink to be supplied to the recording head; an ink tank containing ink to be supplied to the sub tank; a detector configured to detect an amount of ink contained in the sub tank; a variable volume member provided between the recording head and the sub tank and configured to change inner volume; and a controller configured to repeatedly perform first operation and second operation, thereby supplying the ink from the ink tank to the sub tank, the first operation causing the variable volume member to switch from a first state to a second state, the second operation causing the variable volume member to switch from the second state to the first state, wherein volume of the variable volume member in the second state is larger than the volume in the first state, wherein the controller prohibits the detector from detecting the amount of the ink during a period of time in which the first operation is performed.
