Abstract
A light-emitting element and light-receiving elements are embedded upright in a single printed wiring board for cooperating with one another in detecting the leader tape portion of a magnetic tape. Such a printed wiring board is fixed to a chassis by means of which a magnetic tape cassette is held in position. This arrangement enables a reduction in the number of leads and connectors, and hence greatly decreases the number of connections to the body of a magnetic recording and reproducing apparatus, thereby improving its adaptability with respect to automated assembly.
