There is provided a liquid droplet forming apparatus comprising: a liquid holding part configured to hold a liquid including precipitating particles; a film member configured to be vibrated so as to eject the liquid held in the liquid holding unit, wherein a nozzle is formed in the film member and the liquid is ejected as a droplet from the nozzle; a vibrating unit configured to vibrate the film member; and a driving unit configured to selectively apply an ejection waveform and a stirring waveform to the vibrating unit, wherein the film member is vibrated to form the droplet in response to applying the ejection waveform and the film member is vibrated without forming the droplet in response to applying the stirring waveform.

A device for detecting the presence or absence of a liquid, which is installed on an ink-jet recording apparatus, is configured to determine the presence or absence of ink in the ink flow path by detecting the reflection of light from a light transmission portion by irradiating light thereon. The light transmission portion is formed on at least a part of the ink path wall that forms the ink flow path for supplying ink to the recording head. As a result, it becomes possible for responding to consumer demands of designing a smaller version of the ink tank, a cost effective production thereof, and the like in addition to provide images with excellent image qualities.

A liquid detection method and a liquid discharging device to detect whether or not a liquid can be supplied in a state in which a liquid channel from a tank for accommodating the liquid to each discharging port of a recording head is not disconnected by a bubble. A detection-signal input terminal is provided at a position where it contacts the liquid. A detection terminal is provided at a position where it does not electrically contact the liquid and is isolated from the liquid within the tank via a lower wall of the tank, made of an insulating plastic material, and the air. An electrical signal is input from a recording apparatus to the detection-signal input terminal via a connection terminal. The input electrical signal is transmitted through the ink within the recording head, the liquid channel within a joint, and the liquid within the tank. The detection terminal, comprising a conductive metal plate provided at a position corresponding to the entire lower surface of the tank, detects the waveform of a voltage. By comparing the detected voltage with a predetermined threshold, it is determined whether or not the liquid can be normally supplied.

A recording apparatus such as a printer for recording onto a recording medium by use of an ink sheet having an ink comprises: a thermal head to heat the ink sheet to thereby record onto the recording medium; a peeling device to peel off the ink sheet from the recording medium after the heating of the ink sheet by the thermal head on the basis of the recording information; and a controller to control the peeling condition of the peeling device on the basis of the recording information so as to initialize the peeling device at the time of the exchange of the ink sheet or the power-ON of the apparatus. With this apparatus, the high quality recording can be certainly performed by a desired color in response to the color information. This apparatus can mount either the uni-color ink ribbon or the two-color ink ribbon. The heating position of the thermal head is controlled so as to start the recording from the print start position in the first or second recordable area which is defined in accordance with the selected one of the uni-color and two-color ink ribbons.

A dot matrix printer comprises a head comprising a plurality of printing elements, a motor for moving the head, an oscillation source for supplying pulses for driving the motor, and varying means for varying the spacing between dots printed by the head at an integer ratio corresponding to the driving pulses put out from the oscillation source.
摘要:
A thermal printer is capable of maintaining the heating elements thereof at a constant temperature to achieve uniform print density and to avoid abnormal heating of the heating elements. For this purpose each heating element receives a stronger driving pulse at the first printing operation in a scan line and receives a weaker driving pulse at the subsequent printing operation.

摘要:
A thermal transfer printer comprising means for identifying space data present between character data in a print data string. When a space portion is detected by the space identifier, the thermal head is moved apart from the platen of the printer and the ink ribbon feed is stopped thereby preventing the waste of the ink ribbon by the space portion in a line.
摘要:
A platen support structure of a thermal transfer printer, for example, has a platen holder holding a platen, a frame supporting two ends of the platen holder, and an indexing mechanism for pivotally supporting the platen holder. The platen holder is curved in the inoperative mode of the printer and is flexed linearly in the operative mode. Clear printing can be performed without irregular line feed.
