A tape cartridge is provided with reliable reel lock and motor/reel coupling mechanisms whose functions are both accomplished during a single motion of the cartridge relative to the drive motor. The motor/reel coupling includes a circular set of gear teeth on the bottom of the tape reel which meshes with a complementary set of gear teeth on a motor coupling rotated by the motor when the cartridge is loaded into the tape drive and the cartridge and motor are moved towards each other. An engagement force to maintain the coupling is provided by an engagement spring in the cartridge which biases the reel towards the motor. Reel locking is accomplished by providing a second circular set of gear teeth on a top side of the tape reel which meshes with a complementary set of gear teeth provided on a slidably mounted locking bracket inside the tape cartridge. A lock spring normally biases the locking bracket towards the top of the tape reel, thus locking the reel when the cartridge is not engaged with the motor. When the cartridge and the drive motor are moved towards each other, the motor coupling engages the bottom of the tape reel, and a projection on the motor coupling extends into the tape cartridge to slide the locking bracket out of engagement with the teeth on the top of the tape reel, thereby unlocking the reel. Thus, reel unlocking and motor/reel coupling are accomplished with a single motion by reliable mechanisms.

The method and unit for braking a metal strip (1), running off a wind-out coiler (2.1) in the form of a coil (1.1) and running onto a wind-on coiler (2.2) again, are to guarantee that a surface of the metal strip remains undamaged and a full effective braking force is exerted on the metal strip (1) by means of an eddy current brake (3.1) with a rotating magnet system (3.2). The above is achieved, whereby the braking force is exerted on the metal strip (1) by means of an induced counter-torque against a support bearing (4) to one side in a non-contact manner, whereby the support bearing (4) may be embodied as a counter roller (4.1).

The machine further includes a note inlet opening (30) and a note outlet opening (28). A note outlet transport (96) extends between the passage area and the note outlet opening. A note inlet transport (98) extends between the passage area and the note inlet opening. A note validator (58) extends adjacent to the note inlet transport for purposes of sensing the validity of notes inserted in the machine. The machine is selectively operative responsive to inputs to receive and deliver notes. The machine is further operative to enable replenishment of notes therein without accessing the interior of the housing.

A lockable chain winder for opening and closing windows has an internal mechanism which includes a stop member (16) which can be moved to engage with the chain winder sprocket (15) in such a manner that the sprocket (15) can freely rotate on one direction, but not in the other direction.

A wind-up type storage container is provided that can easily wind up and store a small or large item, such as a bag, a flag, a sheet, rainwear, etc. and from which such items can be easily pulled out. In order to pull in an item to be stored, a button is pressed to move a wind-up shaft downwardly. A pawl receiving portion is engaged with engaging pawls, and a reel portion is interlocked with a winding shaft. When a reel cord is pulled out, the reel portion is rotated, and the item to be stored is pulled to and wound around a winding shaft. When the button is released, the reel cord is rewound by a restoring force of a power spring. The reel cord is repetitively pulled until the item to be stored is completely stored in the main body capsule.

A recording/reproducing method and a recording/reproducing apparatus for magnetic tapes are provided as a recording/reproducing technique suitable for recording density enhancement of magnetic tapes. The method and apparatus are capable of correctly recording and reproducing data without causing errors even with occurrence of size changes in the widthwise direction of a magnetic tape. In the recording/reproducing method for magnetic tapes in which data tracks and servo tracks are provided, a tape width is detected and a value of the tape width is stored during data recording, and data reproduction is performed while tape tension is controlled so that the tape width during data reproduction is maintained equal to the tape width during data recording.

A printer having a hopper without shaft which performs a print operation on a roll of continuous paper. Detection marks are provided in flanges provided in supported members removably attached to the continuous paper, and the presence/absence of the detection mark in a detection position of an optical sensor is determined. A rear end of the continuous paper in the hopper is determined if the result of determination of the presence/absence of the detection mark during conveyance of the continuous paper is the same. A passage length from the position of the determined rear end of the continuous paper to a print unit is equal to or longer than a predetermined maximum print size. By this arrangement, the rear end of the continuous paper can be detected without upsizing the apparatus and without complicating the structure, and the continuous paper can be effectively utilized without causing shortage of the continuous paper during execution of print operation.
