<p>PURPOSE:To obstruct the pursuing sound recording by few parts, and to make the titled tape recorder small and thin in size by constituting it so that a projection part of a sound recording substrate abuts on a lock part of a lock lever at the time of a reproducing operation, and obstructs a sound recording operation. CONSTITUTION:A tape cassette 21, and a sound recording/reproducing head 22 are attached to a head substrate 23, a punch roller 24 is supported axially so as to be rotatable by an arm 43, and an erasing head 27 is loaded on an erasing lever 28. When a reproducing button 26 is pushed, a lock part 23a of the head substrate 23 is detained to a bend part 33a of a lock plate 33, and a reproducing operation state is held. A shaft 31 which has been fixed to the head substrate 23 slides along a cam hole 30a of a sound recording substrate 30, and the sound recording substrate 30 turns centering around a shaft 32, and in case of setting the reproducing state to the sound recording state, an obstructing part 30c of the sound recording substrate 30 hits against the bend part 33a, and the operation is obstructed.</p> |
