Head module support mechanism, liquid jet head, and liquid jet system

A liquid jet head comprising:

• a plurality of head modules;
• a module support mechanism that supports the plurality of head modules;
• and
• a frame,
• wherein the module support mechanism includes
• a fixing portion that is joined to the frame,
• a movement portion that supports the plurality of head modules and is supported to be movable in a first direction with respect to the fixing portion,
• a first direction movement portion that moves the movement portion that supports the plurality of head modules in the first direction with respect to the fixing portion, and
• a guide portion that guides the movement portion with respect to the fixing portion and to which a rolling guide extending in the first direction is applied, and
• the module support mechanism supports the plurality of head modules which are connected to each other in the first direction.
