A data distributing system wherein an electronic book data storage center which is stored with a plurality of pieces of book data is capable of communicating with electronic book vending machines 2 via a communication line and/or a communication satellite. In each of the vending machines, a storage medium can be inserted. The vending machine selects a piece of book data, which may be desired by the user, based on data stored in the storage medium as data to be to recorded into the storage medium. The user himself or herself can select a piece of book data. Also, the recorded data can be deleted from the storage medium in compliance with the user's request. These vending machines may have a function of casting accounts.
摘要:
An ink jet printer includes a piezoelectric element, and a voltage generation device for applying a voltage to the piezoelectric element. The voltage generation device applies a pulse voltage having a rising edge, a constant amplitude holding portion, and a falling edge for driving a piezoelectric element, whereby ink dots of a plurality of diameters are printed out to reproduce a half tone image. The waveform of the pulse voltage has the voltage boosted more gentle as the pulse amplitude becomes greater. The sudden strain of a piezoelectric element is prevented. An ink droplet of a particularly great diameter can be sprayed out stably. The conventionally encountered satellite dot, dot split noise, and ink hit position offset are prevented.

An inkjet printing apparatus having a print head and a control system to control the discharge of variable size ink drops from the print head. The control system for printing half-tone images applies pulse voltages of varying waveforms to the print head to control the volume of ink discharged, thereby controlling the diameter of a printed ink dot on a receiving print medium.
摘要:
An apparatus and method are disclosed for inkjet printing which includes a piezoelectric member which deforms in response to a voltage to discharge an ink drop, as well as a device for generating an electric field for stabilizing the flight of the ink drop. Additional features include switching the electric field in accordance with image data so that printing large ink drops are stabilized and ink drop anomalies are reduced, while printing of small drops is accomplished without an electric field.

Disclosed is an ink jet recording apparatus and an ink jet head which ejects an ink droplet from an ink chamber via an orifice in response to transformation of a piezoelectric member. The ink jet head has a non-piezoelectric member having a groove; a film provided on the non-piezoelectric member to cover the groove, a space formed between the groove and the film being used as the ink chamber; and a piezoelectric member provided on the film corresponding to the ink room. The piezoelectric member has a plurality of surfaces one of which is fixedly connected with the film corresponding to the ink room and other of which are facing to air.
