Margin-regulator (e.g., Adjustable Margin-stop) Mechanism Patents (Class 400/342)
  • Patent number: 8909371
    Abstract: A pointer is guided by a user of a processing machine in succession to a number of locations of a working space of the processing machine. The pointer has first location determining devices which are arranged at predetermined pointer locations relative to a pointer coordinate system in fixed relationship to the pointer. Through interaction of the first location determining devices with second location determining devices arranged at predetermined locations relative to a machine coordinate system in fixed relationship to the processing machine, data describing a geometric relationship of the location determining devices relative to one another are acquired. These data are transmitted to a control device which determines the position of the pointer in the working space based on the characteristic data and based on the data subdivides the working space into a permitted movement range for a component of the processing machine and a complementary prohibited movement range.

  • Patent number: 6916131
    Abstract: A tandem-type image forming device is provided which includes a plurality of photosensitive drums, a paper edge detecting section to detect a front edge and a rear edge of a sheet of paper, an exposure starting time calculating unit for each of a plurality of photosensitive drums, an exposure inhibiting time calculating unit to inhibit printing, when paper having a length being smaller than a predetermined length of the paper is inserted, on a portion being shorter than preset paper, and a control section to control an entire image forming device. By configuring as above, the tandem-type image forming device can be realized by using only one paper edge detecting sensor and only one detecting circuit. Even when paper having a length being smaller than a preset length of the paper is inserted, no transfer of an image to a place outside of the paper, that is, to a carrying belt occurs.

  • Patent number: 4904099
    Abstract: Character and control code data are input from a keyboard into a memory. A CRT display unit displays one line of data stored in the memory. A printer is automatically activated to print the line of data in response to a carriage return or line feed code, a hyphen near the right margin or a space near the right margin with a character in the right margin position. In the latter case, the next line is displayed starting with the character position following the space. The printer prints the line while the next line is being input and displayed. The margins, tab positions and a hot zone near the right margin are displayed above the line of data while a cursor is displayed below the line. Character codes such as backspace codes are displayed with the data and the positions of the data on the display always correspond to the printed data positions.

    Abstract: A paper sheet setting mechanism in a printer such as an ink jet system printer includes a memory device which stores a desired left setting position at which a left paper pressing roller should be positioned, and a desired right setting position at which a right paper pressing roller should be positioned. C-shaped guide plates are secured to the paper pressing rollers. Each of the C-shaped guide plates includes a roof member which is made contact with a pritrusion secured to a printer head when a shaft of the paper pressing rollers is held at a first stable position. When the printer head is driven to shift while the shaft is held at the first stable position, the paper pressing rollers are shifted on the shaft and controlled to be positioned at the desired left and right setting positions, respectively.

  • Patent number: 4303346
    Abstract: A clutch for stopping lateral motion of a first element or device, such as a print head in a data printer, which moves along an elongated second member such as a rod or bar. The clutch includes a movable clutch member with an aperture through which the elongated bar passes. In a data printer, this bar may be the guide bar along which the print head moves laterally. The print head or other such first member is coupled to the clutch member to move it along the bar so long as the clutch member is aligned generally normal to the bar, in which condition the bar passes freely through the aperture in the clutch member. An actuator aligned with the clutch member along its lateral travel path is put into position at a point along such travel path where it is desired to stop the moving print head or other device, and operates to tilt the clutch member so that it cocks into engagement with the bar. This produces a binding action which prevents any further movement of either the clutch member or the primary device (e.g.

  • Patent number: 4272204
    Abstract: In a typewriter environment, a carrier mounted sensor for calculating the width of a sheet of paper on the platen and for thereafter setting-up margins for that sheet of paper. In addition to supporting the sensor, the carrier supports the printhead and associated apparatus for detecting the position of the carrier relative to the platen at each escapement position of the carrier. The sensor starts its scan at the extreme left position of the carrier and senses the left edge of the paper at a transition from dark-(the platen surface) to-light (the sheet of paper). This transition point is detected and stored. The carrier continues its rightward scan and the right edge of the sheet of paper signals a transition from light-to-dark. This position is detected and stored. The carrier and sensor continue scanning to the right for a specific distance to eliminate errors that are caused by dark areas on the paper that prematurely trigger light-to-dark transitions.

  • Patent number: 4152083
    Abstract: A printing apparatus having a moving carriage with a snap action switch mounted thereon to initialize the left and right margins of the printing apparatus. The carriage is moved to the left until the snap action switch strikes a stop on the frame of the machine. The carriage is then moved a predetermined distance to the right, and a left margin counter is set to zero while a right margin counter is set to a count representative of the width of printing between margins. The counters are incremented and decremented by movement of the carriage with the zero point of each counter representing presence of the carriage at that associated margin. Manual devices are provided for setting a narrower printing field with wider margins at either side by resetting the margin counters. Also, a margin release allows movement of the carriage outside of the narrowed printing field but never outside of a maximum printing field.
