DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to a tape cartridge used as a recording medium of a tape drive unit used as an auxiliary memory unit connected to data processing equipment such as computer, etc.
BACKGROUND ART
Hitherto, there have been used tape cartridges loaded into a tape drive unit used as an auxiliary recording unit for data processing equipment such as computer, etc. and adapted for recording data signals stored in the data memory section of the equipment body side, or recording data signals delivered to the data storage section of the equipment body side.
As a tape cartridge of this kind, there is known a tape cartridge in which a pair of reel support shafts are vertically provided on a base plate in a thin plate form which takes rectangular shape formed by metal such as aluminum, etc. to respectively rotatably support, through these reel support shafts, tape reels of the tape supply side and the tape winding side to wind a magnetic tape as an information recording medium extending over these tape reels, and a tape drive mechanism for allowing the magnetic tape to undergo traveling operation from the tape reel of the tape supply side to the tape reel of the tape winding side is further provided on the base plate.
This tape drive mechanism includes a drive roller rotatably supported on a drive roller support shaft vertically provided on the base plate, and belt guide rollers rotatably supported on a pair of guide support shafts similarly vertically provided on the base plate. Further, the tape drive mechanism includes an endless drive belt laid across the drive roller and a pair of belt guide rollers, and caused to be in force or pressure contact with the outer circumferential surface of the magnetic tape wound on a pair of tape reels. Further, the tape drive mechanism is adapted so that when the tape cartridge is loaded into the auxiliary recording unit, the capstan roller provided on the equipment side is caused to be in pressure-contact with the drive roller so that the drive roller is rotationally operated. When the drive roller is rotationally operated, the endless drive belt is caused to undergo traveling operation. Thus, a pair of tape reels with which the endless belt comes into pressure contact through the magnetic tape wound thereon is rotationally operated. When the tape reels are rotationally operated, the magnetic tape wound between these tape reels is caused to undergo traveling operation from one tape reel toward the other tape reel.
As stated above, the tape cartridge in which a pair of tape reels on which the magnetic tape is wound and a tape drive mechanism for allowing the magnetic tape to undergo traveling operation are provided on the base plate is adapted so that, with one surface of the base plate being as attachment reference surface, reel support shafts on which the tape reels are respectively supported, a drive roller support shaft on which the drive roller is supported, and guide support shafts on which belt guide rollers are supported are vertically provided. Namely, the reel support shafts, the drive roller support shaft and the guide support shafts are vertically provided on one surface of the base plate.
Moreover, at one surface side of the base plate, in order to prevent that the magnetic tape wound between tape reels and/or the tape drive mechanism are damaged resulting from the fact that foreign material comes into therewith or is attached thereto, a cover member is attached in a manner to cover a pair of tape reels on which the magnetic tape is wound and the tape drive mechanism. This cover member is formed by molding synthetic resin material, and is formed so as to take a square casing shape corresponding to the base plate. Further, the cover member is fixed on the base plate by fixing screws inserted through the other surface side of the base plate in the state where the end surface of the circumferential wall formed in a rising manner (hereinafter simply referred to as rising-formed depending upon circumstances) at the circumferential edge thereof is c
