Abstract: A portable electronic apparatus includes a housing having a storing section which has an insertion opening opened to the outside the housing. A HDD pack is stored in the storing section and detachable through the insertion opening. A HDD holder is connected to the HDD pack and detachably fitted in the insertion opening. A pair of sliders are provided on the HDD holder and movable between an engaged position where the sliders are engaged engagement holes formed in the housing to hold the HDD holder in the insertion opening and a retreated position where the sliders are disengaged from the engagement holes to allow the HDD holder to come into and out of the insertion opening. A lock member is provided on the HDD holder and movable between a locking position where the sliders are locked in the engaged position and a releasing position where the sliders are allowed to move.

Abstract: A portable computer has a housing in which a storing section is formed. The storing section has an opening which is opened to a top face of the housing between a keyboard and a top rear end portion of the housing. A battery pack is fitted in the storing section and is detachable from the storing section through the opening. The battery pack has a top face which forms a pan of the top face of the housing. A strip-like holding groove, for receiving a strip-like function label, is formed on the top face of the housing and the top face of the battery pack. A display unit is attached to the housing so as to be rotatable between a closed position in which the display unit covers the keyboard and the opening of the storing section and an opened position in which the keyboard and the top face of the detachable unit are exposed. Display unit supports are attached to the rear end portion of the top face of the housing.

Abstract: An electronic apparatus has a substantially rectangular box-like housing, having a top wall. A storing section is formed in the housing adjacent to the top wall of the housing and having an insertion opening in the housing. A card-like electronic member is detachably insertable into the storing section through the insertion opening in a card inserting direction. A plate like ejecting member is attached to an under side of the top wall of the housing and located above the storing section in the housing so as to be slidable in a direction parallel to the direction in which the electronic member is inserted into the storing section. An operation member on the ejecting member projects outside the housing through an opening formed in the top wall of the housing.

Abstract: A dielectric ceramic body for use in a band-pass filter. The ceramic body has a plurality of through holes formed to extend transversely from one side surface to another side surface which is opposite to the one side surface and arranged in series along a longitudinal direction of the body. Slits are formed on one of the aforementioned two side surfaces between respective two holes. The slits have depths which increase toward end portions of the ceramic body.
