Provided are an electronic apparatus for transporting an item and an operation method thereof. The operation method includes identifying characteristic information of the item, identifying whether the identified characteristic information comprises main characteristic information associated with planned placement, based on a result of whether the identified characteristic information comprises the main characteristic information, identifying a placement space corresponding to the main characteristic information among a plurality of placement spaces or identifying one placement space among the plurality of placement spaces, and controlling a transport device to transport the item to a location corresponding to the identified placement space.

Apparatus for conveying product and operating method thereof

Appratus for conveying product and operating method thereof

Disclosed is a piezoelectric ink jet printer head in which a chamber and an ink storage are integrally formed. A process for manufacturing the ink jet printer head is also disclosed. The ink jet printer head formed by laminating a plurality of plates includes: a) an actuator portion being composed of upper and lower electrodes, a piezoelectric plate inserted between the upper and lower electrodes, a protection layer placed on the upper electrode, and a resilient plate disposed beneath the lower electrode; b) an ink passage portion composed of a spacer disposed beneath the resilient plate and forming a side portion of a chamber, a channel plate disposed beneath the spacer, the channel plate forming an ink passage in one side of the chamber and simultaneously expanding the chamber, and a nozzle plate disposed beneath the channel plate, the nozzle plate forming the lower side of the chamber and having a nozzle communicating with the chamber; and c) an ink-supplying portion formed by a through-hole reaching the ink passage of the channel plate through the actuator portion and the spacer.
