Application: Drive unit, liquid discharge head, and liquid discharge apparatus (Patent ID: US20240149583A1)
The patent filed by Ricoh Co Ltd. describes a driver unit that includes a driver and a holder, both contractible and expandable in their longitudinal directions. The holder applies pressure to the driver and consists of a driver housing and a contact member that contacts the driver's end portion. The contact member can be a screw screwed into the end portion of the holder or a tapered pin fitted between the end portions of the holder and the driver.
Additionally, the driver unit can include an adjuster attached to the holder to adjust the inner dimension of the driver housing. The holder is made of metal that is elastically contractible and expandable, with multiple elongated structures around the driver. Each structure includes a bellows at the tip. The driver unit can be used in a liquid discharge head with a nozzle and a valve to close the nozzle, as well as in a liquid discharge apparatus with a liquid feeder. The driver can also include a piezoelectric element, and the longitudinal dimension of the driver housing in the holder is equal to or larger than the driver's longitudinal dimension.
