Title: Electronic component mounting device
Inventor: AZUMA MASAYUKI
IPC: H05K13/00
Filed: 1993-04-19
Abstract: PURPOSE:To mount electronic components on a substrate at a high speed without vibration by controlling two tables so that one table can position a supplying unit to a picking up position and the other table can decide stopping operation, low-speed operation, or high-speed operation and perform the decided operation. CONSTITUTION:When motors 3b and 4b rotate, tables 3 and 4 make reciprocating motions in a horizontal direction X along a feed screw 5B. Since the motor 3b and 4b are independently driven, the tables 3 and 4 independently move. The tables 3 and 4 perform supplying work by positioning supplying units U housing desired electronic components to a pickup position Q by moving in the central part A of a working area. In addition, the moving distance and moving parameters of the tables 3 and 4 are set based on the positional information of the tables 3 and 4 and unit values of electronic components supplying data and the optimum parameter is selected from among three kinds of moving parameters.

Title: Ink jet printer
Inventor: JINUSHI NAOTOMO
IPC: B41J2/185
Filed: 1981-06-12
Abstract: PURPOSE:To intercept ink splashes by a printer wherein a shield member having an ink droplet passing port is interposed between an ink head and a recording medium opposite to the ink head. CONSTITUTION:Using a screw 12 a shield member 7 is held by a holding member 11 disposed at the front side of carriage 8 on guide shafts 10. The front side corresponds to the forward direction when the carriage 8 is moved forward (to perform jet operation). With this, during the jet operation of ink droplets 2, an ink head 1 and the shield member 7 are driven by means of a wire 9 in cooperation in such a state that a jetting port of the ink head 1 and an ink droplet passing port 6 in the shield member 7 are positioned concentrically to each other. In this state, the ink droplets 2 are jetted on demand, whereupon the ink droplets 2 strike against a recording medium 4 and this generates ink splashes. These ink splashes are dispersed with an air current caused by rotation of a drum 3' and come near attaching on the front face of the ink head 1. But such attachment of ink splashes is prevented by the presence of the shield member 7.
