<p>PROBLEM TO BE SOLVED: To eliminate the scraching of a tape and also to lower the cost of a device by eliminating the lower flange of a guide roller and unitizing a guide for regulating the position of the width direction at the time of drawing out a tape to a tape guiding body. SOLUTION: The flange 10b provided in a tape guiding body 10 by holding a roller 24 with a washer 29 achieves a function equivalent to a lower flange. The relation of respective diametersϕC,ϕA,ϕB of the flange 10b, an upper flange 23 and roller 24 is constituted so as to satisfyϕC>=ϕA>ϕB orϕA>=ϕC>ϕB. As a result, the flange 10b regulates the position of the width direction of a tape until the tape is drawn out from a cassette to be wound around a cylinder and prevents damage of scraches or the like from being imparted on the tape without applying a restricting force to the tape during the tape is running. Thus, even when a guide roller which does not have the lower flange is used in this device, the constant running of the tape is made possible.</p> |
