Abstract: A portable acoustic apparatus includes a sound outlet (3) formed in the front wall (61) of a housing (6); an acoustic converting element (1) fixed in the housing in such a manner that a front chamber (2) is formed between the acoustic converting element and the front wall (61), and a back chamber (4) is formed between the acoustic converting element and the back wall (62) of the housing (6); and a duct (5) that is formed in the front wall (61) around the sound outlet (3) and communicates to the outside of the housing. The minimum inner width W of the outer casing (63) of the housing (6) is made equal to or less than the standard diameter of the human concha.

Abstract: A small-sized and thin flexible recording system including a flexible disk drive and a recording disk is provided. The recording disk has a disk-shaped recording medium and a recording medium cartridge rotatably receiving therein the recording medium. The flexible disk drive includes a magnetic head for recording information into the recording medium or reproducing information recorded in the recording medium, a carriage mechanism for moving the magnetic head, a recording medium drive motor for rotating the recording medium, a frame having an insertion opening through which the recording disk is inserted, a recording medium mounting portion formed adjacent the insertion opening in a direction in which the recording disk is inserted for mounting thereon the recording disk, and a recording-disk ejection mechanism for ejecting the recording disk from the frame.

Abstract: A flexible disk drive has the configuration of a type-2 card for use in a personal computer or other information processing apparatus. The flexible disk drive includes a cabinet for insertion into a card slot in the information processing apparatus, a mechanism for inserting and ejecting a recording medium cartridge containing a recording medium, a head for accessing the recording medium, a head drive actuator for moving the head, a recording medium drive actuator for driving the recording medium, a position device for positioning the recording medium in a predetermined position, and a drive force transfer mechanism for transferring the driving force of the recording medium drive actuator to the recording medium. The components of the flexible disk drive have thin profiles to achieve the form factor of the type-2 card.

Abstract: A recording medium cartridge includes a disk-shaped recording medium and a case housing the recording medium. A window is provided in the case to expose a portion of the recording medium. A shutter is provided on the case to close and expose the window. A latch is movable in a direction perpendicular to the direction of relative movement of the shutter and is linked to the shutter by a band such that movement of the band causes the shutter to selectively close or expose the window. In one embodiment, the recording medium cartridge has a non-zero thickness equal to or less than approximately 2.0 mm.

Abstract: A flexible magnetic disc apparatus comprising a magnetic head portion for recording and reproducing a disc-shaped recording medium and a loading mechanism portion for loading and unloading the recording medium and having a button portion. When the recording medium is loaded, the button portion projects from a panel surface of the flexible magnetic disc apparatus in a first direction. When the button portion is depressed in a second direction opposite to the first direction, the button portion causes the loading mechanism portion to unload the recording medium. The button portion is capable of being elastically deformed in a direction other than the first direction and may be rubber which has a rubber hardness of a range of from 80 to 100. The button portion may be a cylindrical member having a diameter of from 1.0 mm to 3.0 mm and a distance of projection of the button portion being from 3.0 mm to 5.0 mm.

Abstract: A head assembly moving along a long side of a magnetic card, more than one magnetic head rotating in the head assembly for reading/writing data, a rotary transformer and a carriage with a card holding mechanism for keeping a card at a predefined position are provided in a card reader of the present invention. A rotating part of the rotary transformer in the head assembly receives and sends a signal to the magnetic head and a fixing part of the rotary transformer is connected to a reading/writing circuit. On the card of the present invention, which is usually rectangular, there are tracks defined by plural arcs. The arcs are on plural same-size circles whose centers are aligned on one line along the long side of the card. A magnetic card or an optical card can be used for the present invention.

Abstract: A small and thin storage device that can be substituted for IC memory card is disclosed. When the recording medium cartridge is inserted into the frame of the storage device, a slide member in a hub moves parallel to the frame and retracts a shaft under restriction of a restriction member provided in the recording medium cartridge so that the hub and the shaft engage. When the recording medium cartridge is ejected from the frame, the slide member moves parallel to the frame and the shaft under restriction of the restriction member so as to release the engagement of the shaft and the hub.
