摘要： A magnetic tape cartridge includes a cartridge casing formed by upper and lower casing halves and a single reel around which a magnetic tape with a leader pin fixed to its leading end is wound and which is contained in the cartridge casing for rotation. A spring member removably holds upper and lower end portions of the leader pin on the cartridge casing. The spring member includes upper and lower holding portions which are respectively brought into abutment against the upper and lower end portions of the leader pin and are connected to each other.

摘要： A magnetic tape cartridge is equipped with a cartridge, a single tape reel, a tape leader pin, and a U-shaped clip. The cartridge case is formed by fastening upper and lower cases of synthetic resin together and has a tape leader opening formed in the upper and lower side walls of the upper and lower cases. The single tape reel has magnetic tape wound thereon and is rotatably housed within the cartridge case. The tape leader pin is firmly attached to a leading end of the magnetic tape, and is detachably held in an upright state between the upper and lower cases so that it faces the tape leader opening. The U-shaped clip is attached to walls near the tape leader opening to fasten the upper and lower cases together, whereby the fastening strength of the upper and lower cases is enhanced.

摘要： Disclosed herein is a magnetic tape cartridge including a cartridge case in which a single reel with magnetic tape wound on an outer periphery of a reel drum is rotatably housed. The magnetic tape cartridge further includes a locking member, provided within the reel drum so that it is movable between a locking position and an unlocking position in the axial direction of the reel. The locking member is used for locking the reel to restrain rotation of the reel during periods of non-use. In the magnetic tape cartridge, a first radial clearance between the locking member and the reel drum is set smaller than a second radial clearance between the reel and the cartridge case so that when the magnetic tape cartridge is vertically loaded into a cartridge drive unit, chucking failure is prevented.
摘要翻译：本文公开了一种磁带盒，其包括盒壳体，其中卷绕在卷筒鼓的外周上的具有磁带的单个卷轴可旋转地容纳。磁带盒还包括锁定构件，该锁定构件设置在卷轴鼓内，使得其能够在卷轴的轴向方向上的锁定位置和解锁位置之间移动。锁定构件用于锁定卷轴以在不使用期间限制卷轴的旋转。在磁带盒中，锁定构件和卷轴鼓之间的第一径向间隙被设定为小于卷轴和盒壳体之间的第二径向间隙，使得当磁带盒被垂直地装载到盒驱动单元中时，夹紧故障被阻止。

摘要： A magnetic tape cartridge is equipped with a cartridge case in which a single reel with magnetic tape wound on the outer periphery of a reel hub is rotatably housed. The cartridge is further equipped with a locking member, and a plurality of ribs extending in the axial direction and formed in the inner periphery of the reel hub. The locking member is provided within the reel hub so that it is movable between a locking position and an unlocking position in the axial direction of the reel. The locking member locks the reel to restrain rotation of the reel when not being used. A first radial clearance between the locking member and the ribs at the locking position is set to a value smaller than a second radial clearance between the locking member and the ribs at the unlocking position.

摘要： A magnetic tape cartridge includes a magnetic tape wound around a single reel, a cartridge casing in which the reel is housed for rotation and a reel stopper which locks the reel not to rotate when the magnetic tape cartridge is not being used and releases the reel to permit to rotate when the magnetic tape cartridge is to be used. The reel stopper includes a braking member which is movable between a locking position where it is in contact with the reel to restrict rotation of the reel and a releasing position where it is away from the reel to permit rotation of the same, an urging member which urges the braking member toward the locking position, and a releasing member which is rotated integrally with the reel and moves the braking member toward the releasing position in response to a reel chucking action of the reel drive means of a tape drive. The braking member is provided with a braking gear which is adapted to be engaged, to restrict rotation of the reel, with an engagement gear tooth on an engagement projection formed on the reel while the reel is provided with a guide member which centers the braking member with respect to the reel.

摘要： A single-reel magnetic tape cartridge has a cartridge casing and a single reel around which a magnetic tape is wound and which is contained in the cartridge casing for rotation, in which the magnetic tape is fixed at the leading edge thereof to a leader pin employed for extracting the magnetic tape from the cartridge and the flanges at the upper and lower ends of the leader pin are engaged by the lateral drawing force of a latch spring removably held in the tape cartridge casing. Even for cases in which there is a deviation in the insertion position in which leader pin is inserted by the record and playback apparatus, etc. causing the entry path of the leader pin into the cartridge casing to be off track, etc., it is still possible for the leader pin to be inserted into the cartridge casing. The incline angle, in relation to the insertion direction of the leader pin, at the point at which the flanges of the leader pin are brought into abutment with the guide surface of the latch spring is set within the range of 30°±5°.
