Abstract

PURPOSE:To improve productivity by dividing asymmetrically ribs which form small windows at a heat insertion side at an upper and a lower half, and specifying the length of the ribs of the half so that upper ends of the ribs viewed from the head insertion side do not project upward when the magnetic tape is loaded during assembly. CONSTITUTION:A sheet 15, reel 14, clamper 5, guide roller 6, tape 3, pressure pad 7, pressure pad spring 8, and shield plate 9 are arranged at specific positions of the lower half 20. Further, a sheet 15 is placed and the upper half is stacked to assemble a cassette. In this case, ribs 23a-23d, and 24a-24d for forming small windows in the head insertion surface formed of the lower half 20 and upper half are asymmetrical, and the magnetic tape 3 viewed from the head insertion side is lower than upper ends of the ribs 23a-23d for small window formation of the lower half 20. Consequently, even when the magnetic tape 3 sags when the upper half is stacked, the magnetic tape 3 is never caught between the ribs 23a-23d, and 24a-24d for small window formation of the upper half 21 and lower half 20.
