Abstract: A paper edge sensing apparatus for borderless printing comprises a first paper sensor mounted in connection with the carrier and the frame in the upstream of a paper convey direction of an ink jet position of the ink jet nozzles to detect sheet edges, and a controller controlling operations of the ink jet nozzles of the printer head according to a signal from the first paper sensor to control paper print margins.

Abstract: Disclosed herein is a lead bonding method for SMD packages. The lead bonding method includes the step of placing a package body with its lead-positioning surface facing upward. A lead with solder is arranged on the lead-positioning surface of the package body using vision system. The lead is spot-welded onto the package body to fix the lead to the package body. The package body spot-welded together with the lead is arranged in a positioning depression of a jig with the lead facing downward. The solder formed on the lead are melted to bond the lead to the package body.

Abstract: A paper discharging apparatus for a printer includes: a plurality of support plates for supporting the paper and rotating in a direction parallel to a paper proceeding direction; a rotation shaft of a feed roller arranged in a direction perpendicular to the paper proceeding direction, and to which a feed roller contacting the paper is coupled; a power transfer portion having a sector gear installed on the rotation shaft so that the sector gear doe not rotate when the rotation shaft rotates in a forward direction, and the sector gear does rotate when the rotation shaft rotates in a reverse direction; a crank rod having one end connected to the sector gear, and reciprocating when the sector gear rotates; and a cam shaft connected to the crank rod and rotating in correspondence to the reciprocation of the crank rod.

Abstract: An ink-jet printer has a frame, a carriage, a waste ink collecting box and waste ink spreading device. The paper feeder is mounted to one side of the frame, while a discharge device is mounted to the other side of the frame. The carriage is provided with at least one ink cartridge and is transversely reciprocated between a printing area and a service area along a guide rod that is horizontally mounted to the frame. The waste ink collecting box is for collecting waste ink discharged from the ink cartridge in the service area. The waste ink spreading device uniformly spreads the waste ink heaped in the waste ink collecting box. The waste ink spreading device may have a waste ink spreader.

Abstract: A combined machine for printing and scanning is capable of obtaining a consistent output value from an image pickup device by providing a light source, mounted to a frame, that irradiates a whole line to be scanned or printed. The light source is provided at the rear end of the head assembly which traverses the printing medium or scanning document. The device dries ejected ink in a short time by heat radiated from the light source when performing a printing operation.
