摘要： PURPOSE:To prevent the generation of noxious gas even at high temperature by forming projections for prohibiting movement of the permanent-magnet attaching surface of a yoke, and attaching the permanent magnet by magnetic attracting force. CONSTITUTION:A lower yoke 32 is provided at the lower part of a side yoke 31 of a voice coil motor 30. An upper yoke 33 is provided at the upper part. Lower magnets 35 and 36 having the different polarities are juxtaposed on the surface of the lower yoke 32 facing a center yoke 34. Upper magnets 37 and 38 are juxtaposed on the facing surface of the upper yoke 33. Side magnets 39 and 40 having the different polarities are juxtaposed on the surface of the side yoke 31 facing the center yoke 34. A magnetic circuit is formed on the yokes 31, 32, 33 and 34 and the magnets 35, 36, 37, 38, 39 and 40. Each magnet is attached to each yoke with its own magnetic attracting force. A plurality of projections, which prohibit the movement of the magnet, are provided on the surface of each yoke facing the center yoke 34. Therefore, even if a coil is heated, noxious gas is not generated.

摘要： PURPOSE:To make the projection of a cartridge from a loading/unloading opening when the cartridge is ejected a prescribed quantity by driving a control lever by the turning of an auxiliary lever which interlocks a sutter opening/ closing lever and applying a break to the side face part of the cartridge when it is ejected. CONSTITUTION:The title mechanism is provided with an auxiliary lever 6 which follows and interlocks the turning of a shutter opening/closing lever 4 and a control lever 8 which is turned by the pushing of the auxiliary lever 6 and whose tip part is slided to a side face part 2B of a cartridge 2. When the cartridge 2 is projected from the loading/unloading opening by the prescribed quantity when the cartridge is ejected, the tip part of the control lever 8 is slided to the side face part 2B of the cartridge 2. When the cartridge 2 is ejected from a housing 1, the projection of the cartridge from the loading/unloading opening can always be made a prescribed value.

摘要： PURPOSE:To facilitate a manual cartridge ejection at the time of stoppage by forming a groove to guide an ejection member to be transferred from a forwarding position to a backward position by hand at the time of the stoppage of a drive source. CONSTITUTION:When a cartridge is loaded into a housing 23 which is positioned at its ascended level, an eccentric roller 22 is turned around by 180 deg. to the right by means of the drive of a motor 26, and the ejection member 21 which is engaged with the roller 22 via a groove 24 is moved to the right, the housing 23 is descended with its roller 29 as guided by a sloping cam 25. If the power failure or some trouble is happened on the above arrangement, the member 21 can be pushed by hand to the left because of the roller 22 being positioned in a wide part 31 of the groove 24, thus ascending the housing 23 to enable the cartridge to be ejected out.

摘要： PURPOSE:To increase the positioning accuracy of a magnetic head, by attaching a ferromagnetic material bar on a bobbin and thus suppressing the vibration of a carriage system. CONSTITUTION:A plural number of ferromagnric material bars 30 are attached equidistantly around the main body of a bobbin 5. Thus the magnetic force of a single direction is applied to each bar 30 to attract the bar 30 toward three magnets provided around the magnetic field in the gap of a voice coil motor magnetic circuit or toward a center yoke 2. This is equivalent to the fact that a reinforcing member is provided around the main body of the bobbin 5 to stretch the bobbin toward the outer or inner side. As a result, the circular vibration toward the radius of the bobbin 5 is suppressed significantly.
