A switch has a base having a frame portion disposed integrally with an outer peripheral portion of an upper surface of the base, a common fixed contact disposed at a corner of inside surfaces of the frame portion, and a fixed contact disposed on an inside surface of the base opposite to the common fixed contact, a spring member having elastic arm portions extending respectively from both ends of a bellows-like spring portion, wherein a free end portion of one of the elastic arm portions serves as a sliding movable contact, wherein a free end portion of another of the elastic arm portions serves as a rotationally movable contact, and wherein the rotationally movable contact is positioned so as to be in contact with the common fixed contact of the base, and an operation lever including an operation rib.

Switch

A switch has a base having a recess, and a plurality of fixed contacts mounted in an inner side face of the recess, an electrically conductive actuator disposed within the recess of the base, the electrically conductive actuator having a pair of movable contact portions and an elastically deformable elastic portion, the movable contact portions having movable contacts capable of being connected to respective fixed contacts, at least one engagement convex portion disposed on one of the base and the electrically conductive actuator, and at least one engagement concave portion disposed on the other of the base and the electrically conductive actuator and engageable with the at least one engagement convex portion. The elastic portion of the electrically conductive actuator is elastically deformed to break an engagement between the engagement convex and concave portions when the actuator moves between a first position and a second position.

A switch has a base having a frame integrally formed on a periphery of an upper face of the base, a fixed contact formed on an inner side face of the frame, and a support protrusion that protrudes from the upper face of the base that is integrally formed so as to expose a common fixed contact, an electrically conductive spring member whose connecting part arranged at a center of a spiral spring is nonrotatably supported by the support protrusion and that extends a driving piece from the free end of the spiral spring, and an actuating lever whose one end is rotatably supported by the upper face of the base and that integrally forms an actuating trigger that presses the driving piece of the electrically conductive spring member.

An ultrasonic wave that is transmitted from an ultrasonic-wave transmitter is received by an ultrasonic-wave receiver through a sheet A reception signal is input to an extracting unit The extracting unit compares its phase with a phase of a reference signal output from a reference-signal reproduction unit It converts a phase difference therebetween into a signal having a level corresponding to the phase difference. The signal having a level corresponding to the phase difference is compared with a threshold value set in a threshold-value setter by a comparator When one sheet is fed, the comparator produces a signal of high level. When a doubles feeding occurs, it produces a signal of low level.
