PURPOSE:To improve operability by removably arranging the second cover and a pivotal member to the first cover. CONSTITUTION:Holes 13 are integrally formed on both sides near the tip of the first cover 12 of a cassette main body 11. On the other hand, the second cover 14 is provided with lugs 15a, 15b to be used as rotation fulcrums. In addition, a pivotal pin 16 is provided with a leg section 16a removably and elastically coupled with the hole 13 formed on the first cover 12 and a supporting hole 16b rotatively supporting the lug 15a of the second cover 14. Accordingly, the second cover 14 is assembled as a cassette cover rotatably pivoted to the first cover 12. When the second cover 14 becomes a hindrance for use or operation, the pivotal pin 16 can be simply removed, thus operability can be improved and breakage can be prevented.
