Abstract: PURPOSE:To improve welding resistance further. CONSTITUTION:A contact point switchgear is provided with a low resistance contact point block l having fixed side and movable side low resistance contact points 1a and 1b capable of contacting with/separating from each other and an arc contact point block 2 having excellently welding resistant fixed side and movable side arc contact points 2a and 2b capable of contacting with/ separating from each other, and both the contact point blocks 1 and 2 are formed mutually in a parallel circuit so that the arc contact points 2a and 2b can contact earlier with each other at closing operation time than the low resistance contact points 1a and 1b and can open later at opening operation time. The movable side contact point 2b of the arc contact point block 2 is connected by an extended piece 2f to a mass body 2g situated separately in a direction approximately orthogonal to a direction for contacting with/ separating from the fixed side contact point 2a. Thereby, in the arc contact point block 2, when the contact points are closed, since inertia force of the mass body 2g acts in a direction for preventing the contact points from being opened, contact time of the contact points becomes long, so that the low resistance contact points are closed when a rush current is smaller.

Abstract: PURPOSE:To obtain good printing quality without any difference among layers even if the moment of inertia of movable parts in each layer is different by arranging the energy put into a coil of each layer to compensate said difference in the moment of inertia of movable parts of the layer. CONSTITUTION:When printing is done by a printing head, if a predetermined coil of a predetermined layer, for example, a coil 2A is made conductive, a movable member 5A confronting to an iron core 44 fitted with the coil 2A is attracted to the iron core 4A while an elastic member 7A is being deformed. Accordingly, an end of a wire 6A is, through an ink ribbon and a paper, pressed against a platen 10, thereby realizing printing. In this structure, the energy put into the coils 2A, 2B of each layer is arranged to be different so that the difference in the moment of inertia of the movable parts 34, 38 is compensated. Therefore, even if the moment of inertia of the movable parts 3A, 3B of each layer is different, good printing quality without difference between layers can be obtained.
