[0004] However, if the guide pin is attached to the free end portion of the recording tape or the free end of the guide tape connected to the recording tape in such a manner that the end portion of the leaf spring contacts the flat portion formed on both end portions of the parting line portion portion, the spring forces of the tip portions of the leaf springs at both end portions of the guide pin accommodated in the housing, which hold the both end portions of the guide pin when the guide pin is accommodated in the housing, may not be uniform.

Embodiment Construction

[0040] Hereinafter, exemplary embodiments of the present invention will be described in detail based on the accompanying drawings. For ease of description, in figure 1, the direction in which the recording tape cartridge 10 is loaded into the drive device is indicated by arrow FR, and this direction is referred to as the forward direction (front side) of the recording tape cartridge 10 . The direction of the arrow RI perpendicular to the arrow FR is referred to as a rightward direction (right side). The direction perpendicular to the arrow FR and the arrow RI is indicated by the arrow UP, and is referred to as the upward direction (upper side) of the recording tape cartridge 10 . First, the overall structure of the recording tape cartridge 10 will be described.

[0041] Such as figure 1 As shown, the recording tape cartridge 10 includes a generally rectangular cartridge-shaped housing 12 . The peripheral wall 14B is provided standing upright on the peripheral edge of the t...

Abstract

The invention discloses a recording tape cartridge. A leader pin is fabricated by die-casting, is attached to a free-end portion of a recording tape, and is drawn out through an opening formed in a case. A plate spring retains axial direction both end portions of the leader pin such that the leader pin does not fall from inside the case. When the leader pin is being mounted at or removed from the case, the plate spring is pushed by the end portions and resiliently deforms, and allows the mounting or removal operation of the leader pin. A flat surface portion is formed at the leader pin so as to remove parting line portion of the leader pin. The leader pin is attached to the free-end portion at an angle relative to a tension direction of the free-end portion, such that the flat surface portions formed at the end portions do not contact with the plate spring.

Description

technical field [0001] The present invention relates to a recording tape cartridge accommodating a single reel on which a recording tape such as a magnetic tape mainly used as a recording / reproducing medium for a computer or the like is wound. Background technique [0002] Heretofore, there has been known a recording tape cartridge in which a recording tape such as a magnetic tape used as a data recording / reproducing medium (data backup) for a computer or the like is wound on a reel and the reel is individually housed in a casing. The free end of the recording tape or the free end of the guide tape connected to the recording tape is attached to a guide pin which engages with and is withdrawn from a drawer of the drive device. A method of manufacturing the guide pin by die-casting a metal alloy is known (for example, see Japanese Published Patent Application (JP-A) No. 2010-250873). [0003] On the guide pin manufactured by die-casting a metal alloy, flash (burr), step edge,...
