    摘要： An optical transducer for detecting the angular position of a rotary member with respect to a fixed structure comprises a disc 13 mounted rotatably within a casing. The disc is provided with a plurality of opaque radial regions 19 which are spaced by transparent regions 18 which transmit the light emitted by a light source mounted on the casing. The light is received by a photodetector element 25 comprising a support plate 28 on which is disposed a multiplicity of photovoltaic cells 26 each having an area which is fraction of the area of each transparent region of the disc. The cells are subdivided into three groups A, B and C with different functions and phase positions and are distributed diffusely over the area encountered by the beam of light from the light source. The cells of each group are connected together in parallel to generate three electrical signals, one of which provides pilot control for the feed to the light source to stabilise the signals of the other two groups of photoelectric cells.

    摘要： The device comprises a flange (14) which is fixed to the shaft (12) of the motor and which is provided on its front face with a plurality of radial teeth (28) spaced by recesses each having their active side surfaces parallel to each other and to the radial line through the recess. Removably connected to the character-carrying disc (11) coaxially therewith is another disc (35) of smaller diameter which is provided on its outward front surface with radial teeth (48) having their active side surfaces (50) parallel to each other and capable of being coupled to the radial recesses of the flange which is fixed to the motor shaft. On the other front surface, hooks (38,39) engage in holes (21, 23) in the disc. In an alternative embodiment the teeth (48) are integral with the hub (16) of the disc (11) itself.

    摘要： The device comprises two or more cover plate members (14), whose lengths are submultiples of the lengths of a range of platen rollers (12) and such that two or more plate members disposed in side-by-side relationship cover the entire length of the platen roller. Each plate member (14) comprises a lower guide portion (16) of part-cylindrical shape and two wall portions (17, 18) which are substantially planar and set at different angles of inclination, being connected to the lower guide portion in such a way as to lead in a sheet of paper (19) towards the guide portion. Each plate member (14) is pivotally mounted on a control shaft (22) which is parallel to the axis of the roller (12) and capable of preventing transverse movements of the plate member with respect to the roller, and carries the usual paper pressing rollers (34,36) which are disposed in two parallel rows. A leaf spring (26) co-operates with a lug (24) on the plate member (14) to hold the paper pressing rollers pressed against the platen roller. The control shaft comprises opening cams (57) arranged to co-operate with the leaf springs to disengage same from the respective lugs and to permit the respective plate members to drop away from the platen roller (12), whereby the paper pressing rollers (34, 36) are disengaged from the platen roller to assist in introducing the sheet of paper.
