Abstract: An inventive card-type portable information processing device case permits a user to select a mode in which a card-type portable information processing device is taken out of the case with a cap attached thereto or a mode in which the card-type portable information processing device is taken out of the case with the cap detached therefrom and engaged with the first cover. The inventive case includes a cap engagement portion (15) provided in a first cover (1). By moving the card-type portable information processing device (30) in a direction A, the card-type portable information processing device (30) is taken out of the case with the cap (40) attached thereto. By moving the card-type portable information processing device (30) in a direction C, only the card-type portable information processing device (30) is taken out of the case with the cap (40) engaged in the cap engagement portion (15) of the first cover (1).

Abstract: The present invention provides a thin connector in which contacts to be brought into contact with terminals of a memory card are less liable to be deformed when the connector is assembled or an external force is exerted on the connector. The contacts (4) are located at a lower level than upper surfaces of protective projections (3a), and distal ends of the contacts (4) are located at a higher level than lower surfaces of the protective projections (3a). This prevents the deformation of the contacts, and allows the connector to have a smaller thickness. Further, the contacts are located at a lower level than the upper surfaces of the protective projections when the protective projections are deformed to be brought into contact with bottom portions of recesses of the memory card. Thus, the contacts are less liable to be deformed by an external force.

Abstract: An object of the present invention is to provide a PC card having four SD memory cards therein, which maintains the positional accuracy of the SD memory cards and connectors, and has high contact stability. The PC card includes in its case a printed circuit board (3), connectors (4) secured to the printed circuit board (3), and pressing members (6) secured to the printed circuit board (3). The pressing members (6) hold two SD memory cards respectively, while pressing them to the printed circuit board (3) and the connector (4).

Abstract: In a PC card incorporating a printed board, an electronic component having a greater height can be mounted on the printed board without reducing the strength of a cover. The PC card includes a cover member (1) and a main cover (2) at least one of which is formed with at least one opening (2a) for prevention of interference with an electronic component (4), and a plate member (8) closing the opening from the outside of the cover member or the main cover. An outer surface of the plate member (8) is located at substantially the same level as an outer surface of the cover member (1) or the main cover (2), and the plate member (8) has a smaller thickness than the cover member and the main cover. This arrangement increases the strength of the cover.

Abstract: A mode switch (9) for use in a magnetic recording and reproducing apparatus such as a VTR as well as a signal processing method therefor, in which the mode switch uses a small number of terminals and is prevented from misdetection when noise occurs. If the logic of an output from the mode switch (9) is checked, the output is determined based on an order preset for loading or unloading only if a predicted logic is obtained.

Abstract: A reel braking mechanism for a magnetic tape recording and/or reproducing apparatus includes first and second reels (5L, 5R), and first and second reel support bases (3L, 3R) for rotatably supporting thereon the first and second reels, respectively the first and second reels are movable together with the first and second reel support bases (3L, 3R) between a first cassette position corresponding to a hub-to-hub distance in a standard tape cassette and a second cassette position corresponding to a hub-to-hub distance for a compact tape cassette. The reel braking mechanism includes a brake lever (7L, 7R) movably mounted on each of the first and second reel support bases (3L, 3R) and having a first arm (7a) engageable with the corresponding reel and a second arm (7b). The brake lever is movable between an engaged position in which the first arm (7a) is engaged with the corresponding reel to hold the reel and a disengaged position in which the first arm (7a) is disengaged from the corresponding reel.

Abstract: A magnetic recording and reproducing apparatus including a cassette discriminating device for discriminating a large cassette having first supply and take-up reels and a small cassette having second supply and take-up reels, a first reel base engageable with the first and second supply reels, a second reel base engageable with the first take-up reel, a third reel base engageable with the second take-up reel, which is lifted and lowered vertically, a first cassette loading device for loading the large cassette onto the first and second reel bases so as to hold the third reel base at a lowered position before completion of loading of the large cassette, a second cassette loading device for loading the small cassette onto the first and third reel bases so as to hold the third reel base at a lifted position before completion of loading of the small cassette and a rotational power transmission device for transmitting a rotational force to the third reel base when the third reel base is held at the lifted position.
