Abstract:
PROBLEM TO BE SOLVED: To provide an inkjet printer using phase-change ink printing on continuous web. SOLUTION: A web W which is wound around a spool 10 is fed to a printing section 20 along a path (in the processing direction P) through a roller 12 or the like located on the downstream side. The phase-change ink is loaded on the web W by using printing heads 21A to 21D (they may be one piece) in the printing section 20. A pre-heater 18 which pre-heats the web W to a specified pre-heating temperature is located between the spool 10 and the printing section 20. A means for keeping the temperature of the web W within a specified ink receiving temperature zone, e.g., backing materials 24A to 24D are located in the printing section 20. The temperature of the web W in the printing section 20 can be controlled so that each color ink sequential loading by the printing heads 21A to 21D can favorably be performed.

PROBLEM TO BE SOLVED: To provide an electrophotographic printing machine recording an electrostatic latent image on an oblong photoconductive belt provided with a long shaft and a short shaft. SOLUTION: In this electrophotographic printing machine, the oblong photoconductive belt 10 provided with a long shaft and a short shaft, N pieces of image recording stations 20, 22, 24 installed in the vicinity of the outer surface of the photoconductive belt 10 on one side of the long shaft of the photoconductive belt 10 to record the electrostatic latent image on the photoreceptor belt 10 and N-1 pieces of image recording stations 16, 18 installed in the vicinity of the outer surface of the photoconductive belt 10, on the opposite side of the long shaft are provided.
Abstract:
PROBLEM TO BE SOLVED: To obtain an encoding device which has enhanced accuracy and simple structure and can be produced at a low cost by providing an encoding wheel coming into contact with a part of the span of a web and an extended supporting member for supporting the span and the other part. SOLUTION: The encoding wheel 72 is provided in proximity to the inside surface of a belt 22, to operate linked with it. The wheel 72 is fixed on a shaft 74 and this shaft 74 is supported by bearing parts 76 and 78. The bearing parts 76 and 78 are fixed in a frame 70 for supporting the constituting parts of a printer, as a whole. The end on a side opposite to the wheel 72, of the shaft 74 is connected to an encoder circuit 68. Then, the belt supporting member shown by a roller 80 is provided to support the span part of the belt 22 with which the wheel 72 does not come into contact. The wheel 72 is installed so that the outer periphery 82 of the wheel 72 and the outer periphery of the roller 80 have the same plane, along a line in contact with the belt.

PROBLEM TO BE SOLVED: To restrain the slip of a belt at the time of driving the belt. SOLUTION: A belt driving module and a corresponding method include or adopt the belt moving along a path, at least one supporting roller or another structural body to support the belt when the belt is moved along the path, a driving roller to move the belt along the path, a tension roller to apply tensile force to the belt in order to maintain the coupling of the belt with the driving roller and/or the supporting roller, at least one processing station (for example, image processing station) arranged along the path in order to perform a process related to the specified position of the belt, and a torque supporting and driving part to apply torque supporting force Td at a position between the driving roller and the tension roller. The torque supporting force Td makes the exact positioning of the belt easy by reducing the slip between the driving roller and the belt.

PROBLEM TO BE SOLVED: To provide a device for removing dust particles deposited on the rear side of an image forming surface of a photoreceptor belt or drive rollers. SOLUTION: This foamed pad type cleaning device 94 consists of 1) an endless conductive foamed pad belt which has conductive foamed pads 110 extending outward from a base body 190 and is electrically biased, 2) rollers 102, 104, 106 and 108 around which the foamed pad belt is put and 3) flicker bars 120 which remove the collected particles from the foamed pads 110. One of the rollers supporting the foamed pad belt is the drive roller which moves the foamed pad belt by rotation and brings the clean foamed pads 110 into contact with the rear side of the photoreceptor belt 12.
