摘要： A sheet end detector comprising a light-emitting element and a light-receiving element for detecting changes in the amount of light associated with movement of a piece of a recording medium is provided. A standard value calculator detects the difference between the sheet end detector platen voltage Vp corresponding to light reflected only from said platen and said sheet end detector paper saturation voltage Vm corresponding to light reflected only from the recording medium. The amount necessary to feed the paper for platen voltage Vp to reach paper saturation voltage Vm is a constant value, irrespective of recording medium characteristics, which is when all of the light is reflected by the recording medium and the entire end portion of a piece of a recording medium has reached a predetermined position relative to the position of the sheet end detector. A standard value is calculated by multiplying this difference by a constant coefficient C and then adding back the lesser of Vp or Vm, C being a numerical value greater than 0 and less than 1 and being an indication of the desired position of the leading edge of the recording medium. A comparator compares the standard value and a signal from the sheet end detector and determines when the signal corresponds to the standard value, which is indicative that the presence of a leading edge or trailing edge of the recording medium has reached a predetermined position.

摘要： A method of printing on a printing medium is provided, including providing a printing head for printing on a recording medium and conveying the recording medium in a first direction with a conveyer. A detector is positioned on the upstream side of the print head, the detector then detecting a trailing edge of the recording medium. The amount of recording medium conveyance by the conveyer upon the detection of said trailing edge is computed and it is determined whether the recording medium is of a standard size. Thereafter, a printing region on the recording medium is defined in accordance with the size of the recording medium if the recording medium is a standard size. A printer for printing on a printing medium which employs the above method is also provided wherein a detector is positioned upstream of the print head for detecting a trailing edge of the recording medium which is being conveyed. A computer computes the amount of the recording medium conveyance by the conveyer upon the detection of the trailing edge by the detector, and a size determiner determines whether the recording medium is of a standard size and defines a printing region on the recording medium in accordance with the size of the recording medium if the recording medium is of a standard size.

摘要： A ribbon mask for use with a impact dot matrix printer is provided. The ribbon mask comprises a head confronting surface and a pair of opposed side plates each positioned on an opposite side of the head confronting surface. An obtuse angle is formed between said head confronting surface each of the opposed side plates. A pair of fitting tabs are also provided. Each fitting tab is positioned on one of the pair of opposed side plates. An acute angle is formed between each of the fitting tabs and a plane parallel to a plane in which the head confronting surface lies. As a result of this construction, when the ribbon mask comes in contact with a sheet of a recording medium, the ribbon mask is deformed so that a portion of the head confronting surface comes into contact with an end of a recording head, which in turn prevents the ribbon mask from interfering with the sheet of the recording medium.

摘要： A control method is provided for an ink jet recording apparatus 30 including a recording head 32 for ejecting ink to a medium 31, a heating means 46 for heating the recording head 32, an ink storage part 12 which reserves ink supplied to the recording head 32, and a negative pressure adjusting part 40 which adjusts a pressure in an inside of the ink storage part 12 to be a negative pressure. In the control method, when the ink jet recording apparatus 30 is to be turned off, heating of the recording head 32 by the heating part 46 is turned off but the negative pressure adjusting part 40 is left to be in an “ON” state so that the negative pressure in the inside of the ink storage part 12 is maintained and, after that, the negative pressure adjusting part 40 is turned off.

摘要： A mechanism for switching a paper holding roller of an automatically feeding printer between a contact position for holding a paper against the platen and a separation position away from the platen utilizing the platen power source. A transmission mechanism includes a trigger which is moved selectively by an electro-magnetic member to engage a gear between the platen power source and a roller lever on which the paper holding roller is mounted to move the paper holding roller between the contact/separation positions. In one embodiment, two partial gears engage a gear portion of the lever to move the lever in both directions. In another embodiment, an epicyclic lever is selectively rotated in one of two directions to engage one of two oppositely rotating epicyclic gears to move the paper holding roller.
