Abstract:
1. A recording tape cartridge comprising: a substantially rectangular-shaped case in which a single reel around which a recording tape is wound is rotatably accommodated; an opening which is formed by notching a corner, on a front side in a direction of loading the case into a drive apparatus, of the case and from which a leader member attached at an end of the recording tape is pulled out; a shielding member having a flat plate shape, which is provided in the case and can be selectively positioned between a close position in which the shielding member is inclined from the loading direction to close the opening and an open position in which the shielding member is disposed substantially along a side wall parallel to the loading direction in the case to open the opening; a compression coil spring disposed along the side wall and applying an urging force to the shielding member toward the close position; an operation portion provided at the shielding member, which comes into engagement with an engagement member of the drive apparatus by an operation of loading of the case to the drive apparatus, thereby applying a moving force to the shielding member toward the open position; and a guide provided at the case, which guides the shielding member so that the shielding member travels between the close position and the open position while changing orientation thereof by the urging force or the moving force.
