Abstract: An image forming device provided with a main cover 6 that is capable of freely opening and closing and that covers an internally provided recording medium feed mechanism and the area scanned by the recording head during recording operations; and a maintenance cover 7 that is provided separately from the main cover in order to cover the maintenance mechanism and that is capable of freely opening and closing. Being provided separately from the main cover, the maintenance cover can be constructed relatively small and is, therefore, easy to open and close when replacing the maintenance paper. In addition, by only opening the maintenance cover while the recording head is positioned in the scanning area, the temperature of the recording head is not lowered.

Abstract: A printer is provided with: a heating device for heating a solid ink to dissolve the solid ink into a liquefied ink while an alternative current is supplied thereto; a recording device, on which the heating device is provided, for recording record information onto a record sheet by use of the liquefied ink; and a moving device for moving the recording device.

Abstract: In the position detection device, a timing fence is formed with a plurality of slits which are arranged in its elongated direction. An elongated metal member is provided for supporting the timing fence so that the timing fences will extend in the scanning direction of the image recording head. An encoder is provided for counting the slits on the timing fence while the carriage moves. A gap between the encoder and the elongated metal member can be adjusted properly and uniformly through rotating eccentric collars of the adjustment members inserted into the elongated through-holes in the elongated metal member.

Abstract: An ink cartridge retains a plurality of solid inks, each of which is to be heated and dissolved so that the dissolved ink is used for recording record information. The ink cartridge is provided with: a cartridge main body in which the solid inks are aligned and retained; and a plurality of gap members disposed in the cartridge main body for prescribing a gap between each pair of the aligned solid inks adjacent to each other in the cartridge main body.

Abstract: Disclosed is an image forming apparatus for forming an image on roll paper. The image forming apparatus is provided with a printing head to form an image in accordance with an image data, a sheet feed mechanism to feed the roll paper, and a cutter which cuts out the printed portion of the roll paper. The image forming apparatus is further provided with an information recording system which records information related to the roll paper on downstream side of the portion at which the cutter cuts the roll paper.

Abstract: In the charging device, when the secondary battery is charged, charging electrodes are electrically connected to the battery electrodes. When charging of the battery is completed, charging operation of the charging device is completed, and the charging electrodes are moved away from the battery electrodes so that the charging electrodes are disconnected from the battery electrodes.

Abstract: A checkwriter has a tray for containing check forms having a transparent cover with a scaled region provided with scale lines. The tray is detachably loaded into the check printing unit thereof. When the cover is closed, the surface of the top check form among check forms stacked in the tray can be observed through the transparent cover, and print starting positions where the printing operation for printing desired words for items is started can be measured using the scale lines. The measured print starting positions are registered to correctly print the desired words for the items at predetermined positions on the check form. Since the cover is combined with the tray, it is prevented from being lost.

Abstract: In a label adhesion device for automatically adhering a plurality of labels on one side of a plurality of adhered to members, a cassette storing an ink ribbon, a first roll type support member on which a plurality of print labels are temporarily adhered and a second roll type support member on which a plurality of cover labels are temporarily adhered is detachably mounted on a movable carriage for movement along one side or end portion of an adhered to member inserted in a sheet inlet provided on a main body case of the label adhesion device. The carriage includes a print head for printing desired character image on a projected portion of the label, a drive unit for feeding the first roll type support member and the second roll type support member in a predetermined direction, and a pressing unit for pressing the print label and the cover label holding the adhered member therebetween.

Abstract: To eliminate wasteful use of thermal stencil paper and thereby provide an inexpensive stamp device, a single thermal head is employed for both the thermal recording on a reversible thermal recording sheet for confirmation of a stamp image and the thermal perforation through the thermal stencil paper for creation of a stamp original. The stamp image is first thermally recorded on the reversible thermal recording sheet; the stamp image thus recorded is then confirmed; and the thermal stencil paper is thermally perforated in accordance with the stamp image to create the stamp original.

Abstract: A battery powered serial printer having a print head for printing data on a printing sheet in a normal direction from the beginning of a line or in the reverse direction from the end of a line includes a drive unit for moving the print head in reciprocatory movement in the normal and reverse directions, and a device for judging whether the print head is printing characters in the normal direction or in the reverse direction. The serial printer further includes a correcting device responsive to voltage changes for delaying the initiation of the operation of printing characters by the print head at the least in either the normal direction and/or the reverse direction judged by the judging device, so as to bring the positions of characters printed in the normal direction into alignment with the positions of characters printed in the reverse direction.

Abstract: A thermal printer is provided with a detecting member adapted to detect the presence of a thermal ribbon cassette on the printer. When the thermal ribbon cassette is mounted on the printer, the thermal print head is held at a release position until a cycle of ribbon feeding action has been completed. The thermal head is moved from the release position to a print position to print data on the next line, after the used part of the thermal ribbon has been taken up and an unused part of the thermal ribbon is positioned opposite a sheet of ordinary paper.

Abstract: A printer having a thermal print head capable of printing directly on heat-sensitive paper, and printing on non-heat-sensitive paper through a thermal ribbon. The printer comprises a carriage drive circuit for moving the thermal print head along a platen for printing each line of characters, and a detector for sensing the thermal ribbon to check if the thermal ribbon is usable or not. The printer further comprises a control device responsive to a signal from the detector, for selecting, while the thermal ribbon is sensed, a unidirectional printing mode in which the printing movements of the thermal print head take place in a predetermined one of the opposite longitudinal directions of the platen, and selecting, while the thermal ribbon is not sensed, a bidirectional printing mode in which the printing movements take place in either one of the opposite longitudinal directions.

Abstract: In a ribbon changing mechanism, a ribbon retaining portion of the ribbon vibrator lifts a printing ribbon from a lowered non-printing position to an elevated printing position, in response to the printing operation. When a push button is depressed for retaining an actuating lever in a first position where said ribbon vibrator is shifted to a ribbon changing position, the ribbon vibrator connected to the actuating lever is moved upward from the lowered non-printing position to the ribbon changing position, independently of the printing operation and retained in the ribbon changing position. The ribbon retaining portion is comprised of a rear ribbon retaining member and a front ribbon retaining member, which defines a pair of ribbon passages having closed top and bottom portions in combination with both ribbon retaining members.
