Liquid discharge head and liquid discharge apparatus

A media processing apparatus, comprising:

• a liquid applier including a liquid applying member, the liquid applier configured to apply liquid to a medium;
• a post-processing device configured to process a plurality of media including the medium to which the liquid has been applied;
• a first liquid storage configured to store the liquid applied to the medium;
• a liquid supply portion including:
• a distal end connected to the liquid applying member, and
• a base end configured to be immersed in the liquid stored in the first liquid storage;
• and
• a first liquid-level detector configured to detect a liquid level of the liquid stored in the first liquid storage, the first liquid-level detector including:
• a first liquid-level detecting member,
• a second liquid-level detecting member, and
• a third liquid-level detecting member, wherein
• a lower end of the second liquid-level detecting member is disposed in a substantially same range including a position of the base end of the liquid supply portion in a vertical direction,
• a lower end of the first liquid-level detecting member is above the substantially same range, and
• a lower end of the third liquid-level detecting member is below the substantially same range.
