    摘要： An electronic keyboard comprises a plurality of depressable keys each one of which comprises a stem normally movable and connected through a spring to a metallic actuator. Each actuator is lodged in a supporting element jutting out from the stem and cooperates with a permanent magnet which retains it in a rest position. Upon the depression of a key, the corresponding spring is loaded and after a predetermined displacement of the key a shoulder of the supporting element cooperates directly with the corresponding actuator disengaging it from the permanent magnet. The actuator is then pushed by the action of the spring to a movable contact of an electronic switch which generates an electrical signal.

    摘要： Keyboard for calculating, accounting and other office machines, comprising a series of keys each connected to a corresponding setting element and a series of code bars associated with a series of switching means. The code bars are shiftable by the setting elements in a first or a second position and restoring means cooperate with the bars for positioning the code bars at rest in a position intermediate between the first and second position in order to cause the bars to be shifted by the same amount by the setting element on the depression of any key. The switching means generate a setting-in signal when the bars are positioned by said setting element and connected to a pulse shaper to generate a start pulse of shape independent of the setting-in signal.

    摘要： Magnetic keyboard transforms the depression of a key to electric signals corresponding to a numerical code, comprising circuits having superimposed coils, magnetically decoupled by a conductive disc placed in the immediate vicinity of the primary circuit. The depression of a key moves the conductive disc away and couples the secondary coil to the primary coil.

    摘要： An actuating key for use in a business machine having an electromagnet positioned therein so that the key may be operated by actuation of the electromagnet or may be actuated manually by the depression of the key cap. The key cap partially covers the electromagnet so as to prevent foreign matter from entering the mechanism and interfering with its operation. Also the core of the electromagnet is not attached to the key cap so that when the key is operated electromagnetically, the key cap does not move to the depressed position.

    摘要： An impact transducer switch includes a manually operable key, an energy storage spring, and a piezoelectric element. Upon actuation of the key, means is provided for moving said spring through a first range of movement where energy is stored in said spring, and for thereafter effecting release of said spring at a predetermined point to cause release of said energy and impact of said piezoelectric element to cause an electrical signal to be generated by said piezoelectric element. In one form, an end of the energy storage spring impacts the piezoelectric element, while in another form, the spring transfers the energy to an impact means which in turn causes the impact.
