Definitions

  • the invention relates to a housing for a typewriter or similar office machine of the type specified in the preamble of claim 1.
  • More complex typewriters and automatic text machines are also equipped with a line display device which reproduces at least some of the last entered characters before they are written out on the record carrier. Using this display device, the operator can check his drawing input and, if necessary, correct it before writing it out.
  • the invention has for its object to provide a housing for a typewriter or similar machine with a housing cover movably mounted from a closed position into a functional element such as an ink ribbon cassette, typewriter, etc. arranged on a carriage that can be moved along the writing line, due to the better working conditions be created for the operator.
  • a functional element such as an ink ribbon cassette, typewriter, etc. arranged on a carriage that can be moved along the writing line, due to the better working conditions be created for the operator.
  • the housing cover ensures that the housing cover remains connected to the housing when it is pushed into the open position and thereby enables easy operation.
  • the housing cover is pushed so far over the keyboard that its keys can no longer be actuated. This reliably prevents incorrect operation or unwanted triggering of functions via the buttons.
  • the inventive features according to claim 3 provide a comprehensive and easy-to-read line display device, the operator only having to change the viewing direction to a small extent in order to observe both the writing line on the recording medium and the display on the display device.
  • a largely natural posture can be maintained and maintained, which prevents excessive flexion of the neck vertebrae and cramping of the back muscles. The work is considerably less tiring for the operator, and diseases of the neck spine and back muscles are prevented.
  • the figure shows a housing 1 of a typewriter with a housing cover 11 arranged in an upper housing part 3 between a typewriter 5 and a keys 7 and having a keyboard 9 15, type wheel 17, etc. releasably mounted opening position.
  • a paper sheet 19 can be transported in a known manner via the drivable platen roller 5 and can be derived via a paper guide 21.
  • the housing cover 11 is displaceably mounted in the upper end part 3 by means of a parallel guide and lies in the open position closely above the keys 7 of the keyboard 9 in such a way that the keys 7 of the keyboard 9 can no longer be actuated by the operator.
  • the housing cover 11 has a rectangular recess 23, in which a line display device 25, which displays at least one complete line, is mounted so that it can be pivoted and locked.
  • the line display device 25 known as the display is electrically connected via a guide cable 27 to a control device fixedly arranged on the base plate 29 of the housing 1.
  • the line display device 25 consists of a display representing several lines, which is arranged embedded in a frame 31.
  • This frame 31 has in the middle on the sides 33, 35 bearing journals 37, 39 which are pivotably mounted in bearing bores 41, 43 of the upper housing part 3.
  • the frame 31 is provided on an underside 45 of a longitudinal side 47 with a protruding brake arm 49, which is formed by two brake cams 51, 53 resilient against one another of a brake member (55) made of plastic is applied.
  • the brake cams 51, 53 are with the free ends of on the fork-shaped brake member 55 arranged holding arms 57, 59 formed in one piece.
  • the brake member 55 is arranged by means of a locking pin 61 in a bore 63 of the housing cover 11 so as to ensure a long service life of the spring action of the holding arms 57, 59, the holding arms 57, 59 with the brake cams 51, 53 are pressed against one another by a snap ring 65 .
  • the parallel guide for moving the housing cover 11 has two pivot levers 67, 69, of which one pivot lever 67, 69 is mounted on the two sides in the machine frame.
  • the pivot levers 67, 69 are each articulated via a connecting arm 71, 73 to the housing cover 11 in the vicinity of the front longitudinal edge 75.
  • the parallel guide in the area of the rear longitudinal side 77 of the housing cover 11 has on the underside 79 guides 81, 83 which are slidably mounted on guide edges 85, 87 of the upper housing part 3.
  • These guide edges 85, 87 are the side edges in the opening 89 for the housing cover 11 in the upper housing part 3.
  • the pivot levers 67, 69 each have a Einhotgearm 91, 93 for serving as locking members springs 95, 97, which are hooked with their other ends in such hangings 99, 101 of the floor pan 29 such that the springs 95, 97 when moving the housing cover 11 can be pivoted into the two end positions via a dead center position. This ensures a secure locking of the housing cover in the two end positions without the need for special locking elements.
  • the two pivot levers 67, 69 are fixedly connected to a common axis of rotation 103, which is rotatably mounted in the bottom pan 29.
  • a pivot lever 69 has a stop arm 105 for a switch 107 in the floor pan 29, via which (107) the power supply to the components in the machine can be interrupted. This ensures that no functions can be triggered when the housing cover 11 is open.
