Ink container and ink jet recording system

摘要

The invention relates to an ink container (1), which comprises: a body (20) for retaining ink; a latch lever (30) which has a fixed end (34) connected to the body and a free end, the latch lever being movable between a first position in which a distance between the free end and the body is a first distance and a second position in which a distance between the free end and the body is a second distance smaller than the first distance; a light emitting portion (51); and a light guide member (36) provided on the latch lever and movable in conjunction with the latch lever, the light guide member (i) having a light receiving portion (33) configured to receive light from the light emitting portion when the latch lever is at the second position and a light-outputting portion (31) configured to output the light and (ii) being configured to guide the light from the light receiving portion to the light-outputting portion. A distance between the light receiving portion and the light emitting portion when the latch lever is at the second position is smaller than a distance between the light receiving portion and the light emitting portion when the latch lever is at the first position.
