There is a loading opening through which the thermal printer component is supplied with the recording sheet. Plural guiding projections position the recording sheet in the loading opening. A recording sheet package includes a packaging case for containing a loose stack of plural recording sheets. The loading opening is loadable with the packaging case. A package outlet is formed in the packaging case for passage of each recording sheet, and set directed toward the thermal printer component. Plural cutouts are formed in a periphery of the packaging case, and receive the guiding projections. Blocking portions of a blocking frame are disposed inside the packaging case, and close the cut-outs. The blocking portions are shiftable inwards from the cutouts by the guiding projections.

Recording sheet package and sheet supply cassette for printer

A recording sheet package includes a stack of plural recording sheets. A packaging body contains the recording sheets. The packaging body or the recording sheets include humidity and temperature indicators which allows the degradation of the recording sheets to be compensated for in the course of thermal printing. A detection cutout is formed in the packaging body, for receiving insertion of a sheet remainder counter. The sheet remainder counter is allowed to push the recording sheets in a thickness direction thereof. The sheet remainder counter is adapted to detect a number of remaining ones of the recording sheets in the packaging body.

A thermosensitive recording sheet includes a support and three thermosensitive coloring layers overlaid on the support. A print is produced by image recording to the recording sheet. A colorless gloss indicia is recorded by thermal recording, and discernible according to a glossiness difference. In a preferred embodiment, an image reading device comprises an image reader for reading an image from an original. A glossmeter unit measures glossiness of respectively unit areas in the original. An arithmetic operation unit obtains an average glossiness of the glossiness of respectively the unit areas. An indicia discriminator checks existence of a gloss indicia according to a glossiness difference between the glossiness of respectively the unit areas and the average glossiness. A controller allows the image reader to operate if the gloss indicia lacks, and generates an alarm signal if the gloss indicia exists.

A thermal printer includes a thermal printer component for image recording to a thermosensitive recording sheet. There is a loading opening through which the thermal printer component is supplied with the recording sheet. Plural guiding projections position the recording sheet in the loading opening. A recording sheet package includes a packaging case for containing a stack of plural recording sheets with looseness. The loading opening is loadable with the packaging case. A package outlet is formed in the packaging case for passage of each recording sheet, and set directed toward the thermal printer component. Plural cutouts are formed in a periphery of the packaging case, and receive the guiding projections. Blocking portions of a blocking frame are disposed inside the packaging case, and close the cutouts. The blocking portions are shiftable inwards from the cutouts by the guiding projections.

In magenta fixation, when a rear end of a recording area reaches a first fixation area, a small shutter plate moves at a speed equal to conveyance of a recording material. When a shutter plate reaches a shutting position to cover a low-intensity area, a controller stops conveyance of the recording material. Then, Electromagnetic rays are applied to a rear portion of the stationary recording sheet, until an amount of applied rays of the rear end is equal to that of a front portion. Since the rear end of the recording area is faced to a high-intensity area, fixation time can be shortened without enlarging printer size.

An optical fixing device of a color thermal printer is used for fixing one of three color developing thermosensitive layers of a color thermosensitive recording medium. A pair of lamps are disposed side by side in a reflector of the optical fixing device, for projecting electromagnetic rays of a specific wavelength range toward the color thermosensitive recording medium. A plurality of apertures are formed through the reflector to provide a light path from each of the lamps to a single photosensor, wherein distances from the lamps to the photosensor are different from each other, and incident angles of the respective light paths onto the photosensor are determined such that the photosensor may receive an equal amount of electromagnetic rays from each of the lamps under the same conditions.

Color thermal printer and optical fixing device therefor

A color thermal printer for printing a full-color image in frame-sequential fashion to a color thermosensitive recording sheet (12) including yellow, magenta and cyan coloring layers (26-28). A fixing station is disposed next to a thermal head (18). One of first and second fixing devices (30, 31) is alternatively set in a fixing station. While recording a yellow frame on the recording sheet transported in a forward direction to the fixing station, the first fixing device (30) is set in the fixing station to project ultraviolet rays for fixing the yellow coloring layer (28) onto the recording sheet. While the recording sheet temporarily stops with its end nipped between a pair of transport rollers, a shutter plate (70) is inserted between the recording sheet and the first fixing device still projecting the ultraviolet rays, at the same speed as the transport speed of the recording sheet to uniformly and sufficiently fix as much area of the recording sheet as possible. After the yellow fixation, the recording sheet is moved in a reverse direction toward the thermal head. While recording a magenta frame, the second fixing device (31) generates ultraviolet rays for fixing the magenta coloring layer (27).

A color thermal printer has a thermal head (18) for printing a full-color image in frame-sequential fashion to a color thermosensitive recording sheet (12), which includes at least yellow, magenta and cyan thermosensitive coloring layers (26-28) for developing yellow, magenta and cyan colors. Two transport rollers (22) nip and transport the recording sheet (12) while a thermal head (18) records to the recording sheet (12). At least one first fixing lamp (30, 70, 76) generates ultraviolet rays associated with the yellow coloring layer (28). At least one second fixing lamp (31, 71, 77) generates ultraviolet rays associated with the magenta coloring layer (27). The recording sheet (12) is fixed in a fixing station by the first and second fixing lamps (30, 31; 70, 71; 76, 77), which are supported by a fixer support device (35, 72, 74) in fashion selectively settable in the fixing station. The two fixing lamps (30, 31; 70, 71; 76, 77) are arrangeable substantially equally near to the two transport rollers (22) when set in the fixing station.

A thermal printer for use with a thermosensitive recording sheet is provided with an optical fixing device which has at least a lamp to optically fix a thermosensitive color developing layer of the recording medium. The lamp extends across a transport path of the recording sheet such that an intermediate portion of the lamp where luminance is approximately uniform extends over a range exceeding a maximum width of the recording sheet. A photosensor is disposed on a lateral side of the recording sheet so as to receive electromagnetic rays from the intermediate portion of the lamp. A control device controls the quantity of electromagnetic rays generated from the lamp in accordance with an illuminance value detected by the photosensor, so as to maintain the illuminance of an illumination area in front of the lamp to be constant.
