<p>PURPOSE: To attain accurate positioning by matching a tape guiding pin at an inclined angle with respect to the rotary shaft line of a tape recording and/or reproducing drum. CONSTITUTION: A recording or reproducing drum 40 is provided on a drum holding plate 42, while a tape guiding pin 48 is provided on the drum holding plate 42 closely to the tape recording and/or reproducing drum 40 so that a relative position may not change during the recording and/or reproducing operation. The holding plate 42 is firmly provided on a base plate or between the side walls of the housing so as to remain still during the tape recording and/or reproducing operation. In this case, the two tape guiding pins 48 are provided which are firmly installed on the still holding plate 42 and which are positioned closely to the tape recording and/or reproducing device 40 ; and also, the two tape guiding pins 48 are matched at an inclined angle concerning the rotary shaft line of the tape recording and/or reproducing drum 40. As a result, accurate positioning is made possible.</p> |
