摘要:
A magnetic head for recording information on a recording disk which has a head body that has a sliding sole which contacts the recording disk. The head body is supported by a three-piece leaf spring which has one end connected to a support and the other end connected to the head body. The support member includes a stopper which engages the end of the second portion of the leaf spring so as to control the position of the head body.

A magnetic head apparatus for a magneto-optical recording medium recording and/or reproducing apparatus includes a head body and an arm-shaped support mechanism. The head body includes a magnetic head unit for generating a perpendicular magnetic field, and a contact-slide portion to which the magnetic head unit is secured and which is slid along the magneto-optical recording medium in contact with the surface of the magneto-optical recording medium. The arm support mechanism to which the head body is secured is movable in such a direction that the magnetic head unit is contacted with or away from the magneto-optical recording medium. The arm-shaped support mechanism has an arm portion, a fixed portion and first and second elastic displacing portions. The head body is secured to one end side of the arm portion through the first elastic displacing portion. The fixed portion has one end secured to the fixed member and the other end portion has one end secured to the fixed member and the other end which is linked to the other end of the arm portion through the second elastic displacing portion. The arm-shaped support mechanism is disposed so as to sandwich the central axial line of the support mechanism, and it comprises a pair of plate-shaped elastic members constituting the first and second elastic displacing portions, and a resin portion which is provided at both sides of at least one of the elastic members and forms the arm portion and the fixed portion.

A portable electronic tool comprising a body for the portable electronic tool; a cable; and an engaging mechanism, so that the cable is stored while the cable is wound by the engaging mechanism around the external surface of the electronic tool body. A first and a second protrusion are provided at the respective ends of the body and prevent the cable from slipping off the body when the cable is wound around the body. The engaging mechanism includes a terminal tool, which is provided at the distal end of the cable, and a recessed portion, which is provided in the first protrusion, wherein the terminal tool is retained. A guide member is provided to guide, in a direction in which the cable is wound, the base end portion of the cable so as to prevent the base end of the cable from being projected outward from the body when the cable is wound around the body. The terminal tool is so designed that selective attachment of various types of plugs is possible.

A photographic film cassette has photographic film wound on a spool and rotatably contained in a cassette shell. A leader of the photographic film is caused by rotation of the spool to advance outward from a passage mouth thereof. Two positioning holes are formed in an end face of the cassette shell on an advancing side as inserted into a cassette receiving chamber of a camera, and are fittable on projections of a camera when the cassette shell is loaded therein. Three projections are formed on the end face, and come into contact with an upper inside face of the chamber of the camera when the cassette is loaded in the camera, in order to position the cassette shell vertically. A locking device, which locks the film spool, is unlocked when the film cassette is loaded in the camera.

A sliding type magnetic head for magneto-optical recording which can prevent a jump thereof caused by a variation in profile of a surface of a disk and can realize reduction of a load force and provide a countermeasure against an external impact. A magnetic head body includes a head element having a coil wound on a magnetic core and has a sliding element provided on one side of the head element for slidably contacting with a magneto-optical disk. The magnetic head body is mounted on a gimbal of a slider arm at a position thereof corresponding to the position of the center of gravity thereof or to a position in the proximity of the position of the center of gravity. The slider arm is supported for pivotal motion on a head arm at a position thereof corresponding to the position of the center of gravity thereof or to a position in the proximity of the position of the center of gravity. A coil spring is interposed between the head arm and the sliding element of the magnetic head body.

A positioning mechanism includes a housing, at least one holding member inserted into a lateral opening formed in the housing at the side wall, thereof and an electrostrictive effect element mounted on the holding member. When the electrostrictive effect element is energized, it expands to urge the holding member against a moving member which is to be stopped and held a desired location.

A self-advancing film cassette has at least one separation claw for separating a film leader from a roll of film. This separation claw is disposed within a cassette shell so that it will contact an outermost peripheral surface of a photographic film on the outer side of an area where a picture frame is to be formed. The separation claw is so configured that the contact position between the tip thereof and an end face of a film leader end is 1/3 or more of the film thickness when measured from the outer surface of the photographic film. The film leader projects most at a portion corresponding to the separation claw, and the film leader is formed to be narrow so that it will not be stuck to the film roll. In one embodiment, the film leader is subjected to deformation treatment to form a corrugated leading portion, or to rigidity increasing treatment to form a more rigid leading portion.
