PURPOSE:To cause a construction to be thin and to obtain a thinness and a compactness as a whole by providing a concave part to house a rotary part in the bottom surface part of a guide drum. CONSTITUTION:A concave part 600 is provided in the lower side part on the bottom surface of a power guide drum 3 for a tape 400 traveling, and a motor for a direct-coupled drive is arranged inside it. Thus, the size and construction of a device can be made thin, light-weight and, simultaneously, compact. Since an incorporating work can be executed in always maintaining a device attitude in an erecting condition in the assembling process of the device, the work can be made easy to execute. Further, cylindrical rotary transformers 14 and 15 are used. For such a reason, a space for the transformers in the drum 3 can be reduced, and simultaneously, the crosstalk of a signal can be reduced. |
