Claims

[Claims for Utility Model Registration] 1. A sheet material with excellent slipperiness is used to form a sheet material of sufficient size and shape to fit inside a cassette, and window holes 2 are provided at required positions.
Then, the sheet with the shaft hole 3 is bent so as to alternately form peaks 8 and troughs 9 that are continuous from side to side when viewed from the front.
This sheet for preventing irregular winding of a cassette tape is provided with reinforcing small protrusions 10 facing backwards at required positions of the bent portions, and is provided with a means for equalizing the elasticity of each portion of the sheet. 2. As for the bent shape of the sheet, the left and right longitudinal direction connecting the center of the shaft holes 3, 3 is bent upward as the valley part 5, and the upper and lower sides thereof are bent upward from the part touching the shaft holes 3, 3, and the outside is horizontal. Claim No. 1 of the above-mentioned utility model registration, which is formed by folding back to form a horizontal portion 6.6, and folding down the vicinity of the tips of the horizontal portions 6, 6 downward to bring the tips to approximately the same height as the valley portion 5. The cassette tape winding prevention sheet described in item 1. 3. A plurality of small protrusions 10 are protruded symmetrically with respect to the shaft hole 3 on the upper and lower horizontal parts 6 that contact the reel hub E. A sheet for preventing irregular winding of a cassette tape according to claim 1 of the above-mentioned utility model registration, which is made of: 4. As a means to equalize the elasticity of each part of the seat, the crest 8
and slit holes 11 having arbitrary widths and lengths are opened along the bent sides of the troughs 9 in an arbitrary arrangement to prevent disordered winding of a cassette tape according to claim 1 of the above-mentioned utility model registration claim. sheet.
