Abstract:
1. A liquid discharge apparatus comprising: a liquid cartridge comprising: an apparatus main body comprising: a plurality of sets, each set of the plurality of sets comprising a needle of the plurality of needles and a sealing member of the plurality of sealing members, wherein the needle of each set is inserted into the sealing member of each set, wherein each set is configured to produce a peak load in response to the needle of each set being inserted an initial insertion amount into the sealing member of each set, the peak load corresponding to an increased load produced by each set when the needle of each set is being inserted into the sealing member of each set, wherein each set is further configured to produce a steady load when the needle of each set is further inserted into the sealing member of each set, wherein a magnitude of the steady load is maintained when the needle of each set is further inserted into the sealing member of each set, the steady load being less than the peak load, wherein either the peak load produced by a first set of the plurality of sets is different than the peak load produced by a second set of the plurality of sets or the steady load produced by the first set is different than the steady load produced by the second set, wherein the plurality of needles is configured to receive the peak loads at predetermined intervals in a predetermined order, wherein the predetermined order is one of a plurality of unique orders, each unique order of the plurality of unique orders associated with a greatest load, the greatest load associated with each set corresponding to a greater of the peak load received by a needle of the plurality of needles receiving the peak load first in each unique order and a sum load of the peak load received by a needle of the plurality of needles receiving the peak load after the needle receiving the peak load first in each unique order and the steady load received by a needle of the plurality of needles receiving the peak load before the needle receiving the peak load after the needle receiving the peak load first in each unique order, wherein the greatest load associated with the predetermined order is less than the greatest load associated with each of all others of the plurality of unique orders, wherein the predetermined interval is determined such that a total load received by the plurality of needles when the plurality of needles is being inserted into the plurality of sealing members is equal to or less than the greatest load of the predetermined order, wherein the apparatus main body further comprises: wherein the needle moving mechanism comprises: wherein the plurality of needles is configured to receive the peak loads at the predetermined intervals in the predetermined order based on a length of each needle of the plurality of needles in a direction in which each needle extends from the base.
