A second contact member is arranged in a manner concentric with the dial and circumferentially divided into m (m.gtoreq.2) parts each of which is formed by an electrically conductive portion alone. n.times.s first brushes are arranged on the dial in a manner circumferentially corresponding to the s divisional parts of each of the n first contact member(s). A second brush is arranged on the dial in a manner corresponding to the second contact member. The characters are expressed by k (k.ltoreq.2.sup.(n.times.s) .times.m) identifying patterns out of 2.sup.(n.times.s) .times.m identifying patterns formed by a combination of bit patterns of n.times.s bits generated by contact between the electrically conductive portions and the electrically non-conductive portions of each of the divisional parts of the first contact member and the n.times.s first brushes, and m grouping patterns generated by contact between the m parts of the second contact member and the second brush.
