The invention relates to an electrically driven device comprising a housing (4, 5), an electric motor (1) with a drive shaft (2) having a first rotary axis (I) and a drive pin (3) connected to the drive shaft (2) eccentrically with respect to the rotary axis (I), and a driven shaft (12) mounted in the housing (4, 5) for performing a pivoting. The driven shaft (12) is indirectly coupled to the drive shaft (2) by means of a gear mechanism converting a rotary motion of the drive shaft (2) into a reciprocating pivoting motion of the driven shaft (12). The gear mechanism comprises one intermediate shaft (9, 17, 20) having a second rotary axis (II) extending in the longitudinal direction of the intermediate shaft (9, 17, 20) and at least one crank arm (6, 8, 16) coupled to the drive pin (3). The crank arm (6, 8, 16) is pivotably mounted in the housing (4, 5) and is coupled to the intermediate shaft (9, 17, 20) thereby converting a rotary motion of the drive shaft (2) into a reciprocating pivoting of the intermediate shaft (9, 17, 20) about the second rotary axis (II). The intermediate shaft (9, 17, 20) is coupled to the at least one driven shaft (12) by means of a pivotable bridge (10) such that the intermediate shaft (9, 17, 20) is offset with respect to the at least one driven shaft (12).

The invention relates to an electric shaver comprising at least a first long hair cutter element that is provided with a first under cutter and a first, non-foil type upper cutter, wherein one or both of the first under cutter and the first upper cutter oscillate relative to the other in a direction parallel to an axis x and at least one guard that is provided adjacent to the second upper cutter and extends parallel to axis x, said guard is provided with a comb structure having several teeth each being provided with a skin contact top portion and several slot's being provided between the teeth each being having a low portion for guiding the hair in between and wherein the comb structure is provided as a micro comb structure having a depth of the slots from the top portion of the teeth to the low portion of the slots ranging between 0,2 to 0,7mm.

This slit blade block includes multiple comb teeth adjacent to multiple outer blade pieces. Each comb tooth has a leading end surface, and a protruding part protruding in a direction away from the outer blade pieces. The protruding parts include an apical part that is the outermost end in said direction away from the outer blade pieces. The leading end surfaces of the protruding parts are positioned between the leading end surfaces and the base end surfaces of the adjacent outer blade pieces. Length L1 in the height direction, defined by the apical part of the protruding parts and the leading end surfaces of the protruding parts, is less than or equal to thickness L2 of the outer blade pieces, defined by the leading end surface and the base end surface of the outer blade pieces.

A shaving unit (25) for a dry-shaving apparatus comprises an external first cutting member (1) with an annular wall portion (3) formed with hair-entry apertures (4) and a second internal cutting member (2) which is cooperable with the first cutting member (1) and which comprises a ring of cutters (5) which second cutting member (2) can be driven relative to the first cutting member (1) with an oscillatory rotational movement. The first and second cutting members (1, 2) are interconnected by at least two resilient elements (11) each of which extends substantially radially of the rotational axis of the second cutting member (2) and has an end connected to the first cutting member (1) and an end connected to the second cutting member (2).The elastic properties of the resilient elements (11) are such as to permit the oscillatory rotational movement of the second cutting member (2), but the resilient elements are rigid in direction extending substantially parallel to and radially of the rotational axis of the second cutting member (2).
