In a printing apparatus according to an embodiment of the present invention, it is possible to inspect an image of a printed product where an image is printed accurately without scratching a print medium as the printed product. In the printing apparatus, first, a reading unit reads the image on the print medium conveyed by a conveyance unit, and a fixing unit fixes the print medium to a reading area by the reading unit. Then, control is performed so as to stop conveyance by the conveyance unit and fix the print medium by the fixing unit at the time of image reading, and release fixing of the print medium by the fixing unit and resume conveyance by the conveyance unit if the image reading is complete.

A machine for indirect ink-jet printing and more generally to a machine for indirect digital printing. A first transfer roller is at a printing position at which it provides ink to a first printing roller. The first printing roller engages and transfers ink onto a counter roller for the printing. When its printing has been completed, the first printing roller is moved to a storage position. A second printing roller is selectively moved from a waiting position to the working position to provide ink. The rollers are moved along guides between their positions.

A manufacturing method of an organic thin film transistor includes: forming source and drain electrodes on a substrate; irradiating a photosensitive outer surface with a first charge of a photosensitive roller by laser to pattern the photosensitive outer surface and forming a channel pattern area without charge; spraying an atomized organic material solution with a third charge having same polarity as the first charge onto the channel pattern area to make the organic material solution be absorbed onto the channel pattern area and thereby form a channel region layer; attaching a fourth charge having an opposite polarity to the third charge onto a surface of the substrate disposed with the source and drain electrodes; and transferring a channel pattern in the channel region layer onto the substrate and connected with the source and drain electrodes and thereby forming a channel region. A manufacturing apparatus also is provided.

An active inking system (1) secured to the payer module (25) of the self-service equipment is described. The active inking system (1) includes a modification to the upper cover (4) of the cassette (24), where three upper holes (5) and a front hole (6) are made; the upper holes (5) secure the spreader set (2) and the front hole (6) receives the male quick coupling (13) through which the ink (29) enters. The system (1) comprises a spark sensor (14), component securing structure (12), male quick coupling (13), ink cylinders (15), screws (16), ink outlet connections (20), activation trigger (17), CO.sub.2 gas cylinders (18), tubes (19) and connections (21) for compressed gas. The spreader set (2) comprises a tank (10) aligned with the front hole (6) of the upper cover (4) of the cassette (24), the tank (10) in communication with the spreader tube (8) equipped with orifices (9) directed to the banknotes (7) through which the ink (29) is expelled to mark them. The sparks (27) activate the spark sensor (14), which activates the trigger (17), breaks the seal (28) of the CO.sub.2 cylinder (18), pressurizes the tubes (19) for compressed gas, moves the front (22) and rear (23) plungers and pushes the ink (29).

The present application provides a solder paste dispensing feedback system (10) for a circuit board printer. The system (10) comprises a solder paste container (101), a solder paste extruding device, a first sensor, a second sensor and a control device. The solder paste container (101) is used to contain solder paste and has an outlet. The solder paste extruding device is used to extrude the solder paste from the outlet of the solder paste container (101). The first sensor is used to detect solder paste in the solder paste container (101), and generate a first signal to indicate whether the solder paste container (101) still contains solder paste. The second sensor is used to detect an operating state of the solder paste container (101), and generate a second signal to indicate whether solder paste is extruded from the outlet of the solder paste container (101). The control device is used to receive the first signal and the second signal, and control the operation of the circuit board printer according to the indications of the first signal and the second signal.
