Description

  The present invention relates to a thermal paper on which information is printed by a thermal printer, and more particularly to an information-hiding thermal paper that can conceal printed information.

  2. Description of the Related Art Conventionally, when postal contents related to personal privacy are sent by postcard, a postcard that can conceal information has been used in which two paper base materials are bonded together by adhesive. However, in such a configuration, information is printed on one of the two substrates and then the other substrate needs to be pressure-bonded, which is inconvenient, and an apparatus for that is also necessary. .

  Recently, a thermal recording method as shown in FIG. 3 which is excellent in convenience and can be miniaturized mechanically has been used. In the thermal recording system, information is printed on the base paper by heating from the thermal head while the base paper is covered with the upper paper. For this reason, the information is concealed from the beginning, and is printed on the base paper, so that there is no need for a bonding process or apparatus for concealing the information printed on the base paper.

  On the other hand, since the information concealment printing by the thermal recording method is in a state of information concealment from the time of printing on the base paper, the printing state of the base paper such as the presence or absence of printing failure due to disconnection of the thermal head of the printer is confirmed. I couldn't.

  In view of this, a method has been proposed in which the printing state of the base paper can be confirmed without peeling off the upper paper by using a temperature indicating agent that reversibly develops and decolors according to temperature changes. As a method for making it possible to confirm the printing state with a temperature indicating agent, for example, in Patent Document 1, a temperature indicating ink layer is provided on an upper sheet, and the content of printing is performed without peeling off the upper sheet to which concealment is imparted for a certain period of time after printing. A heat-sensitive paper for concealing confidential information can be confirmed.

  In the thermal recording method, for example, even if you try to check the print status of the information concealment before sending out the print on the thermal postcard, check the print status or unprinted / printed without removing the top paper I couldn't. Even when the temperature indicating ink layer is provided on the upper sheet, the printing state cannot be confirmed in the same manner after a certain period of time has passed. In other words, the print result can be confirmed only within “a certain time” during which the temperature ink layer is at the temperature at which the temperature ink develops, and the length of the time is the temperature of the temperature ink layer on the upper paper after printing. Depends on the speed of change. For example, the length of the “certain time” depends on the room temperature and is unstable, and it is immediately after printing that it can be confirmed reliably. For this reason, when confirming the printing state, for example, the place is assumed to be on the printer side, and an environment in which confirmation work in accordance with the printing speed of the printer is required is assumed, and work efficiency is lowered.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an information-hiding thermal paper that can confirm a printed state or an unprinted / printed state of an information-hidden part at any time after printing regardless of the time elapsed after printing.

  The thermal paper of the present invention is a thermal paper in which a base paper on which information is printed and an upper paper that conceals information printed on the base paper, and the base paper is formed on a part of the upper paper. A transparent portion that transmits information printed on paper is provided.

It is characterized by printing information not included.

  The printing apparatus of the present invention includes a base paper on which information is printed, and an upper paper provided with a transparent portion that conceals information printed on the base paper and partially transmits information printed on the base paper And printing confidential data that is information to be concealed in a range other than the transparent portion of the upper sheet, and the confidential data is in the range of the transparent portion. It is characterized by printing information not including.

  According to the present invention, it is possible to provide an information concealment thermal sheet that can confirm the print state of a portion where information is concealed at any time after printing, regardless of the elapsed time after printing.

It is a figure which shows the information concealment thermal paper which concerns on embodiment of this invention. It is a figure which shows the usage example of the information concealment thermal paper which concerns on embodiment of this invention. It is a figure which shows the conventional information concealment thermal paper.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a schematic view of a top view (a) and a side view (b) of an information hiding thermal paper according to an embodiment of the present invention. As shown in the top view (a) of FIG. 1, the information concealment thermal paper is composed of an upper paper 100 and a base paper 200. In the upper paper 100, the transparent portion 101 has an inverted U shape, and the transparent portion is formed at two upper and lower portions in a direction (horizontal direction) orthogonal to the printing direction of the printer.

  The transparent portion 101 of the upper paper 100 is a transparent film. When printing is performed on the base paper 200 at a position corresponding to the transparent portion 101, the base paper 200 is colored and is provided on the upper paper 100. The transparent part 101 can be seen through. Therefore, if a window is provided so as to extend over the entire width direction of the thermal head of the printer, it becomes easy to check the malfunction (disconnection) of the thermal head. Therefore, the disconnection of the thermal head of the printer can be confirmed at the two transparent portions 101a at the top and bottom. In addition, on the transparent portion 101b in the same direction (vertical direction) as the printing direction of the printer, the item name of the print content to be concealed is printed, and it is possible to check the printing status or unprinted / printed. A portion other than the transparent portion 101 has a tint block so that the content printed on the base paper 200 can be seen through, or a trace remaining on the upper paper surface cannot be confirmed. In addition to the film, the transparent portion 101 may be a paper material through which the content printed on the base paper is transmitted, or the transparent portion 101 may be cut out from the upper paper 100. From the aspect of confirming the printing state of the portion other than the transparent portion 101 from the state, the thermal sensitivity is set between the transparent portion 101 and the other portions so that the print quality does not differ as much as possible between the transparent portion 101 and the portions other than the transparent portion 101. It is desirable to use a material that exhibits close characteristics in copy printing. Further, the transparent portion 101 may be L-shaped, one-shaped, or a combination thereof, in addition to the inverted U-shaped.

  Further, as shown in the side view (b) of FIG. 1, the upper sheet 100 of the information concealment thermal paper is attached by the base paper 200 of the information concealment thermal paper and the adhesive layer 110. The adhesive layer 110 is applied to places other than the printable range. When printing is performed by the thermal printer, printing is performed on the base paper 200 of the information concealment thermal paper from the upper sheet 100 of the information concealment thermal paper that is not the thermal paper by the thermal head. As a result, nothing is printed on the upper sheet of the information concealment thermal paper that is not the thermal paper, while various data are printed on the base paper 200 of the information concealment thermal paper that is the thermal paper, and the information is concealed. The print data to be printed is in a state where the upper paper 100 is covered.

  FIG. 2 is a diagram illustrating a usage example of the information hiding thermal paper according to the embodiment of the present invention. As shown in FIG. 2A, a horizontal line for confirming the disconnection of the thermal head is printed on the upper and lower parts of the transparent part, and various data are printed on the part sandwiched therebetween. Items that can be confirmed from the transparent part are items names that do not need to be concealed (in this case, "name", "address", "current guideline", "previous guideline", etc.), and horizontal lines in the upper and lower parts of the transparent part. At the same time, it is possible to check the printing state or unprinted / printed. The data to be printed on the transparent part may include a customer code number, etc., and the customer database etc. can be searched from the code number so that various data concealed on the cover sheet can be confirmed at any time. Also good.

  Also, as shown in FIG. 2B, the confidential data printed on the base paper 200 under the upper paper 100 (here, “Nippon Taro”) is removed by removing the upper paper 100 of the information concealment thermal paper. , “Tokyo Metropolitan XX Ward ◯ 123-45”, management number, etc.) can be seen directly by the user.
