Two leaf springs of substantially identical width which define first and second movable members are superposed on each other at one end and connected together. A movable contact is attached to the thus connected portion. The first movable member has a slot formed in a middle portion thereof. The width of an end portion of the second movable member is set so that the end portion can be inserted in the slot. A supporting member being inserted in the slot has a portion for swingably supporting an edge portion of the slot and another portion for swingably supporting an end portion of the second movable member opposite to the movable contact. The second movable member is curved so that upon application of a operating force to the first movable member the urging direction of the second movable member changes to cause a snap action to thereby selectively bring the movable contact into contact with one of the two fixed contacts. The width of the second movable member can be increased irrespective of the size of the slot, thus making it possible to provide a large urging force.

A transmitting and receiving system including, a transponder always maintains a transmission function even if circuit constants of circuit elements are deviated or such circuit constants are shifted in association with temperature changes. The transponder includes a transponder coil electromagnetically coupled to an antenna coil through which a response signal is transmitted, a resonance capacitor, a main modulation circuit including a first modulation capacitor, and a supplemental modulation circuit including a second modulation capacitor whose static capacitance value is different from that of the first modulation capacitor. A response signal is transmitted in changing an impedance of a transmitting and receiving portion by the main modulation circuit when a question signal is received and by the supplemental modulation circuit when a correction command signal is received.

A vehicle starting control device which implements inhibiting/enabling of the rotation of a steering shaft when a storing medium is used as an ignition key. A system ECU 19 reads an ID code stored in an IC card 2 via a communication means 24, outputs a permission code to a knob rotation inhibiting means 27 at the time when the system ECU 19 determines that the IC card 2 is an ordinary one, and, when an ignition knob 23 has been set to the LOCK position in an outputting state of the permission code, terminates outputting of the permission code. The knob rotation inhibiting means 27 basically inhibits the rotation of the ignition knob 23, and enables the rotation of the ignition knob 23 in a state in which the permission code is being input. A steering lock means 28 cancels a rotation-inhibiting state of the steering shaft due to a steering lock means 29 in a state that the ignition knob 23 has been set to positions other than the LOCK position.

A card body of an IC card is composed of first and second halves connected by a self hinge portion so as to be foldable into halves in such a manner that the surface where a contact is provided comes inside. The first and second halves are provided with a magnet and a magnetic body to hold the IC card folded by magnetic attractive force. When folded, a control section provided in the first half 1a is connected to transmitting-receiving means and a communication control section that are provided in the second half, by the contact and the transmission-reception contact, so that the IC card can function as a non-contact type IC card.

An object of this invention is to provide a door unlocking device adapted unlock a door by transmitting a signal in the air through a signal transmitter, which can unlock the door even when the power source of the signal transmitter, namely, the battery has consumed up. With a door unlocking device, upon insertion of an ignition key into the rotor of a key cylinder, a shutter is opened to operate a shutter switch. Under this condition, the rotor is turned in opposite directions from the neutral position according to a predetermined rotor turning pattern. The rotor turning pattern is discriminated by a rotor-turning-pattern discriminating circuit. Ensuring that the rotor turning pattern is the one predetermined for unlocking the door, the rotor-turning-pattern discriminating circuit activates an electric operating mechanism to cause a lock mechanism to unlock the door.

A switch device for making a motor or the like alternate between forward reverse rotation, having a pair of switches and a control circuit. When either one of the switches is activated, the control circuit activates the motor in one or the other direction depending upon which switch is activated. When both switches are activated, the control circuit activates the motor until a desired action or task is completed. Therefore, when the present invention is used in a window glass lifting apparatus of an automobile, three kinds of operations of the window glass can be performed by using a pair of switches: partial upward and partial downward movement and continuous movement down to the fully open state of the window glass.

A liquid crystal antidazzle mirror for turning OFF a power of a liquid crystal drive control circuit by a power switch provided between the liquid crystal drive control circuit and a power source comprising a capacitor of a predetermined capacity disposed between the power switch and the liquid crystal drive control circuit and connected in parallel between power lines to supply power from the capacitor to at least a mode memory circuit in the liquid crystal drive control circuit for a predetermined time determined by the discharging characteristic of the capacitor when the power switch is opened. Thus, the mirror can reset the set mode of the antidazzle mirror to the used mode immediately before a power switch is opened when the power switch is closed within a predetermined time after the power switch is opened.

A liquid crystal antidazzle mirror for supplying a power to liquid crystal drive control circuit when a key plate is inserted into a key cylinder which comprises a key position detecting switch for detecting that the key plate is inserted into the key cylinder, and an initializing circuit for initializing the liquid crystal drive control circuit to either special mode of predetermined antidazzle or dazzle state upon receiving a detection signal of the key position detecting switch. Thus, the antidazzle mirror can automatically initialize the antidazzle mirror to either special mode of a predetermined antidazzle and dazzle states when power is supplied from a battery.

An electricity generator is attached to a rotating body having a case secured thereto. The case houses a plurality of rotary members which cannot revolve around the axis of the case but are rotated around their own axes as the case is rotated. A permanent magnet is supported by the rotary members and is rotated in a direction opposite to the direction of rotation of the case. A coil attached to the case generates an alternating current when the permanent magnet is rotated.

A vehicle start-up permission device in which an identification code stored in an electronic key can be kept secret. A start-up permission ECU (1) is magnetically coupled with a transmit-receive controlling circuit (6) of an electronic key (3) via an antenna (2) and an antenna (5) of the electronic key (3) with the electronic key (3) being inserted in an ignition key (4) so as to supply electric power for the circuit. When the ignition switch (4) is operated to an ACC position, the start-up permission ECU (1) transmits a random number code. When the transmit-receive controlling circuit (6) of the electronic key (3) receives the random number code, it converts by predetermined encryption processing a previously registered key code to a return code on the basis of the random number code and returns the return code. When the start-up permission ECU (1) receives the return code, it decodes a key code on the basis of the random number code, and when the key code coincides with the previously registered key code, the start-up permission ECU (1) outputs a start-up permission signal to an engine-controlling ECU (7).
