PURPOSE:To miniaturize a device, simplify constitution and obtain the device which is easily assembled by unifying and forming yokes and spring members for forming armatures. CONSTITUTION:Wire heads 7 are bent unforcedly by means of a guide body 2 housing guide pieces 2a-2d, and arrangement which is at regular intervals and in a straight line at the tips is changed into a shape that is at regular intervals on the circumference at rear ends. Contacting bodies 11 are fixed to the rear ends of the wire heads, and the tips of the contacting bodies 11 are projected outward a stopper 12 by means of coil springs 13 put among the contacting bodies and the guide body 2. The contacting bodies 11 overcome the force of the coil springs 13 because the armatures 6b of a resilient magnetic substance 6 each formed in a case 1 integrally are adsorbed by adsorbing pieces 15, are turned centering around the roots and are pushed, and the tips of each wire head 7 are contacted with a platen. |
