A multi-color recording apparatus is provided with a feeding device for feeding a recording material of determined colors, a recording head for depositing the recording material supplied from the feeding device onto a recording sheet in a pattern corresponding to recording information a detector for detecting the color of the recording material supplied from the feeding device and a control for comparing color information contained in the recording information with the result of the detection by the detector and prohibiting the recording operation of the recording head when there is an absence of coincidence in the color of the recording material and the color information in the recording information.
摘要:
A thermal printer adapted for multicolor printing is provided with a thermal head which is driven according to information of color of character or image to be printed. The color information is previously stored in a memory. The multicolor ribbon used in the printer is composed of different color inks having different melting points coated in layers on a base film. In driving the thermal head, the amount of thermal energy generated from it is changed by changing the applied voltage to it and/or the driving time of it to perform multicolor printing with the multicolor ink ribbon.
摘要:
This invention provides a printer capable of regulating the displacement of printing head according to the kind of characters to be printed. The printer has a printing head, an identifying device for identifying the print size of the printing head, and a drive mechanism for driving the printing head according to the print size identified by the identifying device.
摘要:
A printing apparatus for serial printing by displacement of a printing head, in which a discriminating circuit identifies the typefont of the printing head mounted on the carriage, and a coincidence circuit compares the result of typefont identification with the typefont to be printed and provides alarm if the two are different.
摘要:
A recording head having plural recording elements, a printed circuit board connected to the plural recording elements for power supply thereto, a serial-in-parallel-out driver circuit provided on the printed circuit board for converting the signals to the recording elements into parallel signals, and electrodes provided on the printed circuit board for connection with an external connector.
摘要:
A heat transfer printer prints information while sequentially driving dots of a thermal head to urge them against a platen through a printing paper sheet and a transfer ink ribbon. The printer has a pulse motor or the like which carries the transfer ink ribbon at a speed relative to the stationary printing paper sheet for performing heat transfer printing with the thermal head.
摘要:
The present invention relates to a discharge recovery processing of an ink jet recording apparatus which forms an image on the recording medium by discharging the ink. The invention aims to prevent the increase in the running costs and the shortened life of a waste ink tank by preventing the wasteful ink consumption which may be caused by the dual use of an automatic recovery processing and a manual recovery processing after the replacement of an ink tank.Also, the invention further aims to provide an ink jet recording apparatus with high safety and reliability as well as effecting an appropriate recovery by controlling the movement of head in involving the recovery.
摘要:
A display unit is provided so as to be rotatable with respect to a main body of an electronic apparatus. An inlet for manually inserting a sheet is provided in the vicinity of the center of rotation of the display unit, and a sheet feeding device capable of continuously feeding sheets is provided so as to be detachable with respect to the inlet. It is thereby possible to supply a sheet from the front side of the electronic apparatus.
摘要:
A recording apparatus for recording by discharging plural kinds of ink from the recording head to a recording medium comprises detection device for detecting the decrease of ink remains of each ink of the plural kinds of ink, ink amount indication device arranged in a number smaller than the number of the plural kinds of ink, and signal outputting device for outputting signals which enables the decrease of ink remains having the least amount of ink remains to be displayed on the ink amount indication device in accordance with the results of plural detections by the detection device. In this way, only the ink remains having the least ink remains among those kinds of ink in use is indicated on the display, not the ink remains of all the kinds of ink, thus making it possible to minimize the number of indication devices to make the indication device simpler and smaller or minimize the area on the screen of the display assigned for indicating the ink remains in order to save it for indicating more information other than the ink remains.
