Abstract: PURPOSE: To raise gasification efficiency and heating efficiency by a method wherein a heating means in which a recording material of a recording material accomodating part is heated to be transferred to a material to be recorded is composed of a heating element which extends at least in a depth direction of the recording material accomodating part. CONSTITUTION: When a head 70 is operated as an actual vaporizer, a molten liquid dye 22 sucked up by a capillary phenomenon from a side surface of a piller-shaped body 175A of a micro-heater is heated at about 50-300 deg.C by the piller-shaped heater part 175A ranging over the whole in a depth direction. The dye 22 is vaporized from an upper part hole 150 of an electrode 85 and around an electrode 84 to be stuck to a material to be recorded, and printing can be carried out on photographic paper without any contact. In that case, the dye 22 permeated around the piller-shaped body 175A can be efficiently heated to be vaporized without fleeing. Further, since the heat is generated by the piller-shaped heating element 175A ranging in a depth direction of a dye accomodating part 87, the heat is held sufficiently over the whole of the dye, and there is hardly any influence caused by diffusion on a base 73.

Abstract: PURPOSE: To improve efficiency in gasification by transmitting heat efficiently to a recording material by a method wherein a porous structure which holds and feeds the recording material is provided at a position deeper than that of a heating element provided on a surface area of the recording material. CONSTITUTION: A heating element 75 is arranged on a surface area of a liquified dye 22 in a dye-accomodating part 87 of a printer head 70. Therefore, temperature of the liquified gas 22 is quickly raised on the surface area to make thermal efficiency by heating ascend, and efficiency in transfer of the dye by gasification can be improved. Further, a fine meandering pillar-shaped body 80 for holding and feeding the dye 22 is provided as a porous structure at a position deeper than that of the heating element 75 on the surface area of the dye 22 in contact therewith. Therefore, a capillary structure comes to be provided also to a gasification part 77, running away of the dye is inhibited by capillary action to hold the dye effectively and feed a specific amount thereof, and heat by the heating element 75 can be efficiently transmitted.

Abstract: PURPOSE:To obtain a single-type ribbon cartridge capable of taking a used ink ribbon out of a printer without rewinding it on a ribbon supply reel in a cartridge body and simply replacing the cartridge body. CONSTITUTION:In an approximately cylindrical cartridge body 2 made of a resin and provided with a ribbon supply port 23b, a ribbon supply reel 30 with an ink ribbon 40 wound thereon is rotatably supported. On the top end of the ink ribbon 40, a ribbon lead-out film 41 is bonded. On each side of the ribbon lead-out film 41, a plurality of take-up perforations are provided. In this manner, when the ribbon lead-out film 41 is wound into a cylindrical foam between a pair of take-up reel mounts on a printer side, a ribbon take-up reel 41' having a core of the ribbon lead-out film 41 is formed to be wound with a used ink ribbon.

Abstract: PURPOSE:To diminish the capacity of a rectified DC voltage source, and to miniaturize a set and reduce cost while improving the quality of photographic printing in a battery driven type printer. CONSTITUTION:A rechargeable battery 7 is installed to a power supply for photographic printing, the battery 7 is charged previously by a rectified DC voltage source composed of an AC rectifying section 2, a switching section 3, a voltage control section 4 and a secondary rectifying section 5 at the time of non-photographic printing and electricity is discharged at the time of photographic printing, and power for photographic printing is supplied. A voltage drop by discharge at that time is detected, and an output from the rectified DC voltage source is controlled by a voltage control section 4 so as to correspond to the voltage drop section, and overlapped to the battery 7 through a charge/overlapping changeover section 6 and an over-lapping section 8, and corrected. Consequently, photographic printing voltage is stabilized, and the quality of photographic printing is improved. Accordingly, the rectified DC voltage source is used together with the battery 7, thus diminishing the capacity of the rectified DC voltage source for photographic printing, then saving space and reducing cost.

Abstract: PURPOSE:To make it possible to discriminate used parts and unused parts of an ink ribbon at normal use of printer, emergent power off, and exchange of ink ribbon halfway, and to take out a head of an unused part of the ink ribbon particularly at the exchange of the ink ribbon halfway. CONSTITUTION:An auxiliary head 6 marks an identification mark on a part of a part not to be printed of an ink ribbon 4 by receiving a command from a CPU 17 through an auxiliary head control circuit 18. Because of this identification mark, discrimination of used parts and unused parts at least at every sheet of the ink ribbon is possible. Further, by reading this identification mark by a sensor 7 at, for example, exchange of the ink ribbon, a head of an unused ink ribbon can be taken out and the number of used sheets or remaining quantity can be confirmed.

Abstract: PURPOSE: To always perform good recording by providing a plurality of recording material transfer parts in a common recording material supply passage and transferring a recording material from the recording material transfer part to a material to be recorded to efficiently transfer the same to the recording material transfer part. CONSTITUTION: The liquefied dye 22 flowing in a dye supply passage 84 from each dye housing tank is repelled to one end of a liquid stop part 197 to preliminarily flow in so as to be biased to first and second walls 82a, 102a. Rectangular evaporation holes 68a, 97a, 91a are provided to the heater layer 68, liquid stop layer 97 and protective layer 91 on the heating element 75 arranged to the central part of the second wall 102a to form an evaporation part 77. The liquefied dye 122 in the liquefied dye supply passage 84 is heated and evaporated in the vicinity of the upper part thereof by the heat from the heating element 75 to fly upward and bonded to a material to be recorded to perform recording. The liquefied dye on the heating element 75 consumed by evaporation has a recessed part temporarily and partially but the recessed part is immediately supplied with the dye by the surface tension of the liquefied dye 22 and the flow caused by the wettability of the first and second walls 82a, 102a.
