Abstract: PROBLEM TO BE SOLVED: To obtain an optimum method for driving a carriage corresponding to all combinations by variably controlling a drive system for energizing a motor of a drive source and a profile of accelerating, decelerating or the like based on a type of a unit mounted on the carriage and an identification of the combinations. SOLUTION: A recording head has three terminals 71 to 73, which are respectively pulled up by resistors 74 to 76 and selectively connected to a ground potential by patterns 77 to 79 when the heads are mounted in a body. Thus, eight types of combinations are generated by three signals A, B and C. Combinations of the units mounted on a carriage are identified, and a current profile conducting with a main scanning motor is decided from causes such as combinations of the units, printing mode, ink residue or the like. The motor is driven according to the decided profile. Energy conservation, noise reduction and settling characteristics can be improved.

Abstract: PURPOSE:To increase magnetic efficiency, save power consumption and accelerate operational speed by constituting a plunger with a type drive of non- magnetic material and a flux receiver/sender of magnetic material. CONSTITUTION:When a coil 15 is excited, a flux phi flows through a magnetic circuit consisting of plunger 12   magnetic space G1   the first yoke 16  the second yoke 17   magnetic space G2 and plunger 12 arranged in that order. Then an electromagnetic suction force characteristic becomes a line 14, an electromagnetic force overcomes the spring force of a return spring 18 and the plunger 12 shifts in an arrow W direction. If one end of the plunger 12 reached the most isolated operational position from the bottom 19d of a rear frame 19, the head 22c of a type drive 22 hits a type. The excitation of the coil 15 disappears and the plunger 12 returns to a normal position by an impact repulsive force at the time of hitting the type and the spring force of the return spring 18. As a result, magnetic efficiency is increased to achieve low power consumption and operational speed acceleration.

Abstract: PURPOSE:To slowly perform the deformation in the course of press-forming by providing an inclined surface made by the difference between plate thicknesses and the length exceeding a specific times the difference on a lower (or an upper) die of a press die and positioning a stocks joining part on the inclined surface. CONSTITUTION:The clearance step 12 on the lower die 11 of the press die is an inclined surface and the level difference  t is equal to the difference between the plate thicknesses in the joined stock to be pressed and the length S exceeds 50 times as long as  t. The upper die of the press die is flat and abuts on the flat surface of the joined stock. Joined (laser-welded) stock of plates different in thickness is press-formed by the lower die 11 and a flat upper die so that the joined part different in level comes to a clearance step (inclined surface) 12. S/ T is changed in a range 50-140, and the larger the ratio S/ T is, the smaller the strain quantity ratio H/L of the strain height H near the joined part to the strain range L is. Thus, the deformation in the course of press-forming is made slowly on the inclines surface and the clearance step corresponding to the difference between plate thicknesses does not make trouble to forming.
