摘要： In a differential lever actuator comprising transmission members (41, 42) for differentially transmitting oppositely sensed angular displacements from first and second weight points (P1, P3) of first and second lever members (31, 32) to first and second predetermined points (P2, P4) of a differential lever member (41), a distance between midpoints (S, T) between the first weight and predetermined points and between the second weight and predetermined points is kept constant irrespective of the angular displacements. Preferably, at least one transmission member should be perpendicular to a line passing through the related weight point and a fulcrum point (Q or R) of the associated one of the first and second lever members. When carried by the differential lever member for print of a dot, a rod should preferably have an axis passing through a point of intersection of the transmission members. Alternatively, the differential lever member should have a center of a rotational component of the distance (ST) at a point of percussion related to a reaction resulting from print of the dot. As a further alternative, at least one transmission member should be thicker than 0.05 times a length between the related weight and predetermined points.

摘要： This invention relates to a selective printing mechanism. The printing apparatus includes several carrousels which are themselves mounted on a principal rotating plate. Each carrousel supports, in addition to rotating cylinders having printing characters, charactercarrying elements fixed with respect to the plate of the respective carrousel. The principal rotating plate carries also rotating printing cylinders and character-supporting elements fixed with respect to its plate. The rotating unit thus constituted can be disposed horizontally behind the paper and the whole of this unit and of a percussion element is displaceable horizontally at each stroke, in order to type a line of characters. This apparatus has particularly efficient application to the construction of a typewriter for printing in the Chinese or Japanese languages.

摘要： A bidirectional motor is drivingly connected to two (or two series of) print-wheels via respective one way clutches such that rotation of the motor in one direction causes one (or one series) to be set and rotation in the other direction causes the other (or other series) to be set. A series of print-wheels may be a decade-wheel set in which motion is transmitted from a driven (e.g. units) wheel to a further (e.g. tens) wheel by a Geneva or like mechanism. As described (Fig 3) the motor 49 (which may be in the printhead of a franking machine) drives print-wheels 42 and 422 via clutch 50 and also drives print-wheels 423 and 424 via clutch 51, With respect to the series 42 and 422, the clutch 50 drives a first intermediate gear assembly 472-52 of which the wheel 472 is fully toothed and the wheel 52 has only one tooth. The wheel 472 meshes directly with first print-wheel 422, but the other print-wheel 42 meshes with an idler wheel 471 mounted coaxially on the intermediate gear assembly 472-52. Motion is transmitted from the one-toothed wheel 52 to the idler 471 by a transfer gear 54 (obscured in Fig 3) journalled on a shaft 55 parallel with but behind motor shaft 48. The print-wheel 421 is thereby indexed one digit for each complete revolution of the motor while the print-wheel 422 rotates one whole revolution per motor revolution. In other embodiments there may be two series of printwheels coaxially mounted at axially spaced locations on the motor shaft, each series having its own internal decade mechanism (Fig 2), or the decade mechanism can be dispensed with and two motors may set four printwheels directly with each motor controlling alternate wheels (Fig 1).

With this differential lever actuator the transmission members (41, 42) are not severely deformed during operation and do not break even during repeated operation.

摘要： A release latch (8) of the key lever (2) with a pivot (21) and spring (29) is constructed as an integral component made of elastic plastic. The spring is constructed as a tongue (29) which is provided at its free end with a holding pin (30) which extends approximately parallel to the pivot (21) and engages in a corresponding bore (32) in the key lever (2). The release latch (8) is provided with a side guiding surface (34) engaging around the key lever (2) in the region of a longitudinal edge and is connected to the key lever by plugging in. This obviates the need for riveting and for hooking in springs for all the key levers with release latches on a typewriter.

摘要： A hand-operated typewriter with a segment shift mechanism has several key lever shafts supported on a frame in several rows at different heights and at different distances from the front or operator side of a frame (the type being towards the rear side of the frame) for pivotally mounting key levers, the number of shafts being more than the number of key rows. The key levers corresponding to the keys which are positioned in an outer part of each row of keys (i.e., away from the center or inner part of the typewriter) are pivotally supported on a shaft which is disposed at a position higher than the shaft on which the key levers corresponding to keys positioned in a center part of each row are supported, so as to make the strokes of all the keys depressions uniform.
