In the setting operation conducted by the handle,which is an operating section, an upper portion of the portion,&prime; of the slidable T-post,is pushed by the end portion of the cam,, and the slidable T-post,is moved. In accordance with the movement of the card,, the suction cup block,is elastically deformed, and the suction cup,is held by the body,by a holding force of the suction cup,. The body,is composed of a porous body, and air flows from the ventilation hole,into a space formed between the suction cup,and the body,, via the body,. The slidable T-post,is biased ahead by the return spring,. When the releasing operation is conducted by the handle,, the cam,is rotated, and the end portion of the cam,is separated from the end of the portion,&prime; to be pushed. After that, when the intensity of the holding force of the suction cup,to the body,is decreased lower than that of the spring force of the return spring,, the slidable T-post,is moved ahead, so that the card member,pushes up the movable contactor

A moving-coil linear motor is formed with a stator means forming a guide and having a permanent magnet array having opposite poles alternately at constant intervals in longitudinal direction of the stator means, and a mover means mounted on the stator means for being movable through an electromagnetic force along the stator means, the mover means having three-phase moving coils wound in bipolar system on cores U-shaped in section. Positive and negative voltages are alternately applied through brushes to the moving coils of the mover means, while its U-shaped cores are opposed to the permanent magnet array, disposing the array between both leg portions of the U-shaped cores, with the magnetic efficiency of the motor thereby remarkably improved while sufficiently effectively minimizing the size.
