A housing for a paper shredder with a slit-like paper feed disposed on one side of the housing and a slit-like paper discharge disposed on the opposite side of the housing. The housing has an elongated shape, the dimension of length being a multiple of the dimension in width, where on each narrow side of the paper discharge support surfaces are disposed, with which the paper shredder can be placed on a waste receptacle. The width of the support surface is selected such, that one of the support surfaces is considerably larger than the width of the edge of the waste receptacle, while the other support surface has a width only negligibly greater than the width of the edge of the waste receptacle. It is additionally possible to provide a clamping device in the area of one support surface as security against sliding of the paper shredder placed on the waste receptacle.

The plug connection device for mechanical and electrical plug connection of one electronic unit having a first housing (1) with another electronic unit having a second housing (2) includes an electronic plug (5) in the one unit and a socket (6) for the plug (5) in the other unit, and a mechanical locking device separate from the electronic plug (5) in the one unit. The mechanical locking device includes an operating rod or bar (7,7') slidable parallel to a wall of the one unit; at least two plate-like lock studs (10) extending inclined to the wall of the one unit and correspondingly inclined running surfaces (15) bounding lock stud recesses (13) provided in the rear wall of the other electronic unit. After the units are pushed together, the plate-like lock studs (10) are slidable by sliding the operating rod or bar substantially parallel to the wall of the one unit, so that the lock studs (10) engage in the lock stud recesses (13) of the other electronic unit (2) interiorly of running surfaces (15) provided in the second electronic unit (2), the lock studs (10) contacting and running on the running surfaces (15) during electrical connection of the plug and socket.
摘要:
A typewriter or similar machine having a platen turnable by means of a ratchet and a line spacing wheel and a carriage movable along the platen by means of a pulling means, on which a typing element or push button is disposed. In accordance with the invention a so-called lift-rotation motor is used for turning the platen, for line spacing and for moving the carriage. Its turning movement is transferred to the carriage by a pulling means. The axial movement of the motors causes the pivoting of a ratchet support on which the spacing ratchet is disposed which turns the platen by means of a toothed spacing wheel. In this way no additional motor for one of the two functions is required. The lift and rotary movement of the motor can take place temporally superimposed. In this way no time delays occur in the course of operation of the typewriter or of a printer.

A typewriter or similar machine with a print wheel disposed on a shaft drivable by a motor, the characters of which are printed by means of a hammer. In accordance with the invention, use of a separate print magnet is to be omitted. This is made possible by the use of a lift-rotation motor. Its rotational movement is used for the rotational positioning of the print wheel, while the axial movement of the motor shaft is transferred to a print hammer pivotably disposed on the carriage. Determination of the engagement point of the motor shaft with the print hammer makes possible the optimum determination of the movement cycle of the print hammer as well as its print force. Thus the space above the motor for the print wheel, otherwise required for a print magnet, can be used for other purposes. Additionally there is a reduction of the masses which are required to be moved along the platen.

A multi-circuit connector (5) to receive edge contacts of plug-in modules (4) and make electrical contacts with a printed board (2). The connector (5) comprises means (20) to achieve a floating mount in a support (11) having lateral spring tabs (19) and contact clips (6) which project forwardly in parallel rows to make circuit with the board (2). The clips (6) are bent (24) to improve resilience along their own axis to reduce stress on the board (2) when a male module (4) is inserted. Two or more embodiments are disclosed.

In an electronically controlled typewriter, a printer or the like with an exchangeable ribbon cassette, which is provided with identifying codings and where the ribbon cassette is pivotable between a lowered position of rest and an elevated printing or operating position around the cassette base facing away from the printing area, it is provided in order to attain a simple and dependably readable coding which can discriminate between a plurality of different types of ribbon cassettes, that at a defined radial distance from the base of the ribbon cassette, which is to be inserted, a sensor is disposed at the side of the pivot path of the same, which gives off an electrical output signal in reference to a changing magnetic field. It is provided in a ribbon cassette for such a typewriter or such a printer to dispose at least one bistable magnetic element on a lateral surface of the ribbon cassette.

A keyboard for typewriters or similar machines has a key support, switching contacts and key push rods, each of which is acted upon by a spring. The design of the few individual parts assures their simple manufacture (extruded parts and a stamped part) as well as an assembly just as simple and therefore automated, and, if desired, even without screws or aids of that type. Activation of the individual keys takes place with satisfactory tactile feedback and without undesireable vibrations.
