Each contact 40 comprises an anchoring portion 41, a connect portion 43, and a V- shaped arm portion 44, which further includes first and second arm portions 46 and 47 extending from a pivot portion 45. The pivot portion 45 of each contact engages with the connector housing 32d and its movement downward is restricted. A contact portion 48 which is provided at the end of the first arm portion is positioned below the card receiving room 13 of the connector while a push portion 47a which is provided at the end of the second arm portion is positioned in the card receiving room 13. When an IC card 2 is inserted into the card receiving room 13, the tip 2a of the IC card hits and lowers the push portions 47a of the contacts, thereby rocking the V- shaped arm portion 44 of each contact around the pivot portion 45. As a result, the contact portions 48 of the contacts are lifted and brought into contact with the flat contacts of the IC card 2. With this construction, the distance which the flat contacts of the IC card travel sliding on the contact portions of the contacts of the connector is minimized to reduce the wear of the contacts so as to prevent occurrence of contact failure.

A function expanding apparatus for a compact electronic device includes a casing (11) having a supporting portion (21), and a supporting plate (31) attached to the casing to be movable in a predetermined direction. A pair of retaining portions (35) are formed on the supporting plate. The rear portion of the electronic device is mounted on the supporting portion and is positioned in its width direction by a pair of positioning members (20) provided at the supporting portion. The front end portion of the electronic device is mounted on the supporting plate and, the retaining portions engage the front edge of the electronic device so as to restrain the movement of the electronic device in the depth direction thereof. The position of the retaining portion is adjusted by moving the supporting plate, in accordance with the depth of the mounted electronic device.

A sliding member 130 is slidably provided to a housing base 110, and this sliding member 130 is biased forward by a tension spring 170. When the insertion of an IC card 2 is complete, a toggle device 160 keeps the sliding member 130 locked against the biasing force of the tension spring 170. An electromagnetic solenoid 190 attracts a movable magnet core 155 forward when current is supplied, and causes a second arm 150 to swing so that a protrusion 163 on the toggle device 160 is pressed to the left by a protrusion 153. As a result, the above-mentioned lock hold provided by the toggle device 160 is released, and the sliding member 130 is slid forward by the biasing force from the tension spring 170, ejecting the IC card 2.

A modulation and demodulation method is proved for transmitting a data signal, whose data logic is expressed by an H level and an L level. The data signal is converted to a modulated signal for transmission and demodulated upon reception, with the modulated signal comprising pulse signals with duty ratios of H : L = N : 1 and 1 : N or H : L = 1 : N and N : 1 (with N > 1) in correspondence to the H level and the L level of the data signal.

A card connector 1, which is constructed with a main body 11, a flap member 21, a plurality of first contacts 31 and a plurality of second contacts 32, comprises a first connector section 10 and a second connector section 20. The first connector section 10 allows removable insertion of a first card-like memory module 51 through an insertion opening 12 into a slot-like receiving part provided at the lower part of the main body 11 for electrical connection through the first contacts 31, which are aligned and retained in the receiving part. The second connector section 20 allows removable installation of a second card-like memory module 52 for electrical connection through the second contacts 32, which are aligned and retained on the main body above the receiving part, with the flap member 21 being mounted on the upper part of the main body 11 pivotally to be opened and closed for installation of the second card-like memory module 52.

The present invention comprises a housing (10) for holding a card (2) in a receiving space (13); a main unit member (11) comprising contacts (40, 50) for making direct contact with a flat contact disposed on the held card (2); and a cover member (12) mounted in a freely detachable condition to this main unit member (11), and a card ejection mechanism (100) for ejecting a card(2)held in the receiving space (13) is disposed in the cover member (12).
摘要:
A connector element (5) removably holding a card (2) containing stored data is mounted within a case (100) such that the connector element is slidable in the card (2) insert/eject direction, this connector element (5) being normally urgent in the card (2) eject direction by springs (SP1, SP2). A connector element mounting member (120) is provided with a locked portion (125) detained by a locking member (143) urged rightward by a spring (142) when the connector element (5) has been slid in the card (2) insert direction, and the locking member (143) is unlocked by leftward motion thereof by means of magnetic attraction by a solenoid (140) operated by a switch (147).
