Abstract: A conductor device including a plurality of insulators, and a plurality of conductors extending mutually in parallel. Each of the conductors is supported at two positions spaced apart along the longitudinal direction thereof by a pair of the insulators. The conductor device also includes an insulating member provided intermediately along the longitudinal direction between the two supported positions of each of the conductors. The insulating member has a plurality of space portions along a side thereof, and the conductors are positioned in individual ones of the space portions.

Abstract: According to the reciprocal movement of a movable arm, a stationary arm is connected or disconnected to fingers mounted to the movable arm. A metal ring electrically connected to the stationary arm and coated on the front end with an insulator coating surrounds a contact end of the stationary arm.

Abstract: An original pressing device for pressing an original on an original supporting surface by means of an original pressing plate, which device has a plate-like member of synthetic resin, a bending portion formed in the plate-like member, a mounting device provided on one side of the plate-like member with the bending portion as the boundary, the mounting device being for mounting said one side on an original supporting table, an original keeping portion provided on that surface of the plate-like member opposite to the mounted one side, and an abutting portion provided near the bending portion and adapted to be bent and thereby abut with the bending portion to set the angle of bend of the plate-like member, said plate-like member, said bending portion and said abutting portion being formed of a unitary plate-like member of synthetic resin.

Abstract: In a portable type machine, material supporting members adapted to be stretched for use during the use of the machine are pivotally connected to the opposite sides of the machine for upward rotation and during the transportation of the machine, the supporting members are pivoted onto the top of the machine body so as to form a transportation handle on top of the machine body. By one touch, the machine can be transformed from its shape during use into a compact shape suitable for transportation, thus greatly enhancing the transportation efficiency of the machine.
