<p>PURPOSE:To make a device light and small-size and make it possible to perform tape loading surely and smoothly by making the tape loading mechanism small-size. CONSTITUTION:As a tape loading means to lead out a tape from an accommodating box body, a rotation operation means is provided which consists of loading rings 11a and 11b, which have a part of the outside circumference shaped into a gear and can rotate around tape guide drum 10, and a gear which is geared with outside circumference gear parts 120a and 120b of rings 11a and 11b and rotates respective rings. Then, outside circumferences 130a and 130b of rings which are not geared with the rotation operation means are set to a length shrter than the outside diameter of gear part 120a and 120b, and support materials 18a to 18c for respective rings are provided on these shorter outside circumfernce parts. As a result, the constitution of the whole of the device can be made light and small-size.</p> |
