A recording tape cassette comprising a top section and bottom section having a recording tape wound on a pair of tape reels and a pair of tape drawing openings each of which is defined at a front left end and a front right end of a front portion of the tape cassette by top front walls, bottom front walls, and a pair of generally vertical side walls, said recording tape being drawn out of said tape cassette from one of said tape drawing openings and returned to the tape cassette passed through a second tape drawing opening, said recording tape cassette comprising within each of said defined tape drawing openings inner vertical guide walls projecting from said bottom front wall, a top end thereof contacting a lower surface of said top front walls, each of said inner vertical walls having a hollow semi-cylindrical surface along a front end portion thereof for guiding said recording tape in a vertical attitude, a front edge of each of said top front walls being set back from a frontmost portion of said cylindrical surfaces where said lower surfaces of said top walls contact said top ends of said vertical guide walls thereby providing added support to said guide walls preventing bending thereof under force applied by said recording tape, said set back feature preventing damage to said tape if displaced in an upward direction.
- 2. The recording tape cassette according to claim 1, wherein the distance between the front edge of the respective top front wall and the frontmost portion of the respective inner vertical guide wall is greater than play in a widthwise direction of the recording tape in a space between said lower surface of said top front walls and an upper surface of said bottom front walls, such that said upper surface of said respective bottom front wall acts to regulate the height of said recording tape.
- 3. The recording tape cassette according to claim 1, wherein said respective upper surface of said top front wall is stepped lower than an upper surface of a top wall of said top section of the tape cassette.
- 4. A recording tape cassette comprising a top section and bottom section having a recording tape wound on a pair of tape reels and a pair of tape drawing openings each of which is defined at a front left end and a front right end of a front portion of the tape cassette by top front walls, bottom front walls, and a pair of generally vertical side walls, said recording tape being drawn out of said tape cassette from one of said tape drawing openings and returned to the tape cassette passed through a second tape drawing opening, said recording tape being supported by first and second hollow semi-cylindrically shaped tape supporting members vertically provided on said bottom front walls for supporting said recording tape in a vertical attitude, respective front edges of each of said top front walls being set back from frontmost portions of each of said tape supporting members where a lower surface of each of said top front walls contacts respective top ends of said tape support members thereby providing added support to said tape supporting members preventing bending thereof under force applied by said recording tape, said set back feature preventing damage to said tape if displaced in an upward direction.
