摘要： The invention relates to a playback/recording and/or output device for information carriers, especially for compact disc changers with a housing (1) essentially containing several sets of drives and magazines for the information carriers and closable by at least one door (2, 3), and with a computer unit in which the device's program is stored. A door (2) of the device (1) is unlocked by electromagnetic or manual action by the combination of a lock (12) and a system of connecting rods (8) and a set of locking rods (18). The device is constructed in such a way that only authorised persons have access to it and the changing of magazines for the information carriers is permitted only if the device program has completed at least one of the magazines or if the device has to be opened in an emergency owing to operative failures.

摘要： A write protection system 202 is provided for machine-readable data storage disks, such as optical disks, of a single or multiple disk cartridge 100, where write protection of any disk can be individually enabled or disabled while the cartridge is inserted into a disk drive. Separate trays 104, 108 support each of the disks, all trays being housed by a cartridge. When the cartridge is inserted into the disk drive, only a face 103 of the cartridge is exposed. Each tray includes a write protection mechanism positioned near the cartridge face when that tray is housed by the cartridge. Each mechanism provides a user-selectable, machine-readable indication of the protection status of its associated disk. An exemplary mechanism includes a resilient finger 204, deformably pivotable from a released position to an activated position when a deflection pin is pressed against the finger through an activation hole in the cartridge face. A detente 216 is resiliently urged toward the finger, at an intersecting angle thereto. The detente includes a ramp 218 with a catch 220 facing the finger. As the finger moves from its released position to its activated position, the ramp slidably contacts the finger's tip. The catch maintains the finger in its activated position after the tip slides past the catch. Manually extending a deflecting pin against the detente through a releasing hole in the face pivots the detente away from the finger, causing the tip and the catch to move apart, whereupon the finger's resiliency snaps it back into its released position.

摘要： A disk cartridge has a case comprising an upper and a lower shell halves (6, 7) for accommodating a disk. The case has a spindle insertion hole (8), a head insertion hole (9) and a shutter (10) for opening and closing the two holes (8, 9). The case has at least one of a disconnection preventing mechanism (25, 35; 39, 40) for preventing an elastic spring (23) for urging the shutter (10) from being disconnected from a slider (14) and a part of the case, a drive pin smooth motion mechanism (42) for moving a drive pin (P1, P2) on the slider (14), a shutter locking mechanism (56, 60) for locking the shutter (10) at a closing position, a disk center holding mechanism (85, 101, etc.) for supporting the disk at its center position, a disk periphery holding mechanism (18a, 19a) for holding the periphery of the disk, a writing protection mechanism (29a, 29b) for prevention new information from being recorded on the disk and a mechanism (417) for forming the case with a good outer appearance.

摘要： A limited-use tape cassette includes a follower arm (420) pivotally secured to the housing at one end (422) while abutting the spooled tape (8) of a cassette reel (6) at a distal end. A use-limiting mechanism is provided by the follower arm (420) or another inter-related arm to control rewinding and/or playback of the tape based on follower arm position and/or positional history. In one embodiment, a second rotatable arm (30) is located in controlled interference with the follower arm so as to cause it to "lock up" after a predetermined number of unfettered play back/rewind cycles have taken place. In other embodiments, the arrangement (Fig. 12) utilizes existing brake teeth of a tape cassette reel to prevent rewinding after a predetermined amount of the video has been viewed.

摘要： A write protect switch (SW) which comprises a first metal piece (50) in the form of a fixed metal piece, and a second metal piece (40) having an abutting portion (46) for abutting against a recess (2) conesponding to one slide region of a write protect button (3), the abutting portion being positioned substantially at the middle between a contact (45) and a holder (42) or positioned at a location shifted toward the holder (42) from this middle position, wherein it is ensured that both metal pieces (40, 50) reliably and stably move toward and away from each other and contact each other under required pressure, so that the position of the write protect button is accurately and reliably detected.
