  • Patent number: 5588757
    Abstract: A recording apparatus for performing recording uses a carriage mounted with a recording head moving along a guide shaft. The recording apparatus includes a magnetic linear encoder consisting of a scale element magnetized and a detection unit for detecting magnetized information magnetized to the scale element. Provided also are clicks formed on any one of the detection unit and the carriage and click engaging portions formed in the other one of the detection unit and the carriage. The clicks engage with the click engaging portions, whereby the detection unit is snap-locked to the carriage. This enables the detection unit of the magnetic linear encoder to be readily attached to the carriage and besides, when attached, prevents disorder of the information magnetized to the scale element. Further, even when a position of the carriage shifts corresponding to sheets having different thicknesses, a sliding load of the carriage does not change.

  • Patent number: 5584591
    Abstract: When format information is changed, print area check data is generated as per the changed format information (S25). If the check data is found not to be printable within the print area of the tape defined by the printable width and set tape length ("YES" in S27), the changed format information is invalidated (S28), and a message indicating what has taken place appears on the display (S29). Whenever a character or the like is input, the corresponding print check data is generated (S33). If the data is found to be printable within the print area ("NO" in S35), a print-like image of that character is displayed; if the data is found not printable ("YES" in S35), a message indicating the unavailability of printing is displayed (S38), and the corresponding text appears on the display unit (S40).

  • Patent number: 5584590
    Abstract: A printer which includes a paper selector for setting return amount and return amount memories for storing return amounts for at least two kinds of recording paper. The type of recording paper is selected by a printer control command so that a return amount for continuing a printing operation specific to the selected type of recording paper can be set. As a result, printing can be executed once a return amount has been set for each type of recording paper if the user wishes to print on different types of recording paper having different return amounts, thereby reducing the burden on the part of the host computer in controlling the printer and increasing the printing speed of the printer.

  • Patent number: 5580177
    Abstract: A network includes plural client processors, a file server and plural printers. Each client processor has memory that stores a printer driver procedure which enables the client processor to interface with at least one printer type. The file server includes memory for storing a most updated printer driver procedure for each printer type coupled to the file server. The file server is responsive to a print request from a client processor to assign a printer to the requesting client processor. The file server then in combination with the client processor determines if a printer driver procedure for the assigned printer in the client processor is identical to a most updated printer driver procedure stored in memory in the file server. If not, the file server enables alteration of the printer driver procedure in the client processor to bring it into coincidence with the most updated print driver procedure.

  • Patent number: 5577848
    Abstract: A keyboard where no finger pressure is needed to input data, that uses rows of emitters opposed by rows of detectors to detect a finger position, that is environmentally sealed, and inherently intrinsic safe. The keyboard has a mouse function so an operators finger can be tracked to position a cursor on a host display, and input normal keyboard functions. The keyboard has a field changeable coded overlay with indicia thereon so a scan pattern, ambient reference level or other application specific variables can be changed without breaking the environmental seal or powering down the keyboard. Further, the different scan patterns can include scanning the finger position by multiple emitter detector pairs at angles other than ninety degrees to give a cross check of detection. These said scan patterns can be further optimized to scan angled sets of keys and to adjust to different ambient light conditions so errors can be detected by the emitter detector pair closest to detection of a finger.

  • Patent number: 5564848
    Abstract: A media handling subsystem picks a media sheet from a stack, then moves the picked sheet along a media path. Any skewing of the media sheet existing in the media stack or occurring during the pick cycle is removed before the sheet reaches a position to receive print markings. In particular, the alignment of the skewed media sheet is altered (i.e., the sheet is moved) to square the media sheet to the media path. An electro-optic sensor detects when the top of a media sheet enters between a drive roller and pinch roller. Upon entering, the media sheet moves a mechanical flag into the light circuit of the optical sensor. After the media sheet trips the flag, the drive roller moves the top edge of the media sheet backward along the media path out of the grasp of the pinch roller and drive roller. As the sheet moves out of the grasp, the top edge of the sheet falls into squared alignment with the drive roller and pinch roller. The squared media sheet then is moved forward tripping the flag again.

  • Patent number: 5547296
    Abstract: A method of controlling a transportation velocity of a printhead carriage of a serial printer is disclosed. The printhead carriage is driven by a motor via a timing belt. First, a characteristic equation, which includes a motor speed, a current applied to said motor, an equivalent disturbance indicating environmental variations affecting said motor speed, is discreted. Thereafter, the equivalent disturbance is estimated using the characteristic equation which has been discreted. A value of the equivalent disturbance is determined and subsequently, a value of the equivalent disturbance compensating level is calculated using a discrete low pass filter. Finally, a current to be applied to said motor is obtained by adding a compensating level of the controller to the level of the equivalent disturbance.
