DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for forming a mark by heating, and more particularly to an improvement in an apparatus for forming a mark such as a character on a stencil printing plate and a heat-sensitive label by a plate making apparatus.

[0002]

2. Description of the Related Art The applicant of the present invention has previously disclosed a stencil printing plate (heat treatment member) used for stencil printing and a stamp apparatus (mark by heating) for forming marks such as desired characters on the stencil printing plate as perforated images. Forming apparatus) (Japanese Patent Application No. 4-6505). The proposed stamp apparatus and stencil printing plate will be described with reference to FIGS.

As shown in FIGS. 8 (A) and 8 (B), a stencil printing plate 50 includes a heat-sensitive stencil sheet 54 composed of a thermoplastic film 51 and a porous support 53, and a heat-sensitive stencil sheet 54. Separator 5 disposed on porous support 53 side
5, a nonwoven fabric 56 which is an impregnated body impregnated with ink,
A frame 57 made of a hard resin or the like disposed so as to surround the nonwoven fabric 56 and a film 58 as an ink impermeable base material are sequentially laminated. In addition,
Reference numerals 52 and 59 are adhesives.

In the stencil printing plate 50 having such a structure, a perforated image is formed by heating and melting the surface of the thermoplastic film 51 of the heat-sensitive stencil 54 with a plate making apparatus 80 using a thermal head as shown in FIG. (Hereinafter, the formation of a perforated image is referred to as plate making). The stencil printing plate 50 thus made is mounted with the separator 55 inserted into the stamp member 60, and after the separator 55 is removed,
As shown in FIG. 9, stencil printing is performed by pressing the stamp member 60 on the printing paper 70. Reference numeral 61 denotes a handle, reference numeral 62 denotes a cushion layer, and reference numeral 63 denotes an adhesive layer.

[0005] As shown in FIG. 7, the external configuration of the plate making device 80 is an operation section 81 on the front upper surface of the plate making device 80.
A keyboard 82 for inputting a desired perforated image, a display 83 made of liquid crystal for displaying the inputted perforated image, a perforating switch 84 for instructing the start of perforating, and an on / off switch 85 for turning on / off the power supply are provided. Provided. An insertion window 86 for inserting the stencil printing plate 50 is formed on the right side surface of the plate making device 80, and a stamp groove 87 for inserting and placing the stamp member 60 is formed on the rear side upper surface of the plate making device 80. .

[0006] Then, the stencil printing master plate 50 is
0 is inserted through the insertion window 86, and a desired character or the like is entered through the keyboard 82 and displayed on the display 83 for confirmation. When the plate making switch 84 is pressed, the thermal plate disposed inside the plate making device 80 is pressed. Head (not shown)
As a result, the heat-sensitive stencil sheet 54 of the stencil sheet 50 is heated and melted to form the perforated image of the input mark such as a character. Stencil printing plate 5 on which the perforated image is formed
0 is conveyed to the stamp groove 87, and when the handle 61 of the stamp member 60 is pressed in this conveyed state, the stencil printing
0 is adhesively held by the adhesive layer 63. Next, the stamp member 60 on which the stencil printing plate 50 is adhesively held is pulled out from the stamp groove 87, and the ink impregnated in the nonwoven fabric 56 is pulled out of the separator 55 as described above.
4 bleeds out from the surface and can be pressed and printed on the printing paper 70. Here, as shown by reference numeral A in FIG. 7, characters such as ABC are perforated on the “lower surface” of the stencil printing plate 50 conveyed to the stamp groove 87.

On the other hand, it is also possible to apply a heat-sensitive label (heat-sensitive member) 90 shown in FIG. That is, in the thermal label 90, a thermal paper 92 is stuck on the “back side” of a mount 91 made of flexible release paper, and after forming characters and the like by heating, the thermal paper 92 is peeled off from the mount 91. It can be applied to an appropriate place.

[0008]

However, as shown by reference numeral B in FIG. 7, characters such as ABC formed by heating are formed on the "back surface" of the heat-sensitive label 90. Therefore,
The characters and the like after the heating and formed transferred into the stamp groove 87 are
It is not possible to check from above "as is". In other words, in order to check the characters and the like, remove the heat-sensitive label 90 from the stamp groove 87 and “turn it over”.
Need to check from. If such an inside out operation is abolished, the usability of the conventional stamp apparatus (mark forming apparatus by heating) is improved.

The present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to form a mark by heating by changing the transport direction according to the use of a stencil printing plate, a heat-sensitive label, or the like as a heat-treating member. It is intended to provide a device.

[0010]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention conveys a plurality of heat-treating members having heat-sensitive paper for different purposes by a conveying device and heats the heat-sensitive paper to mark characters such as characters. A mark forming device by heating, which is formed on the thermal paper by heating and then discharged to the outside of the apparatus main body, wherein the transfer device is a transfer direction switching device that switches a transfer direction according to the use of the heat processing member after the heat formation. It was configured.

[0011]

The transport direction switching device provided on the transport path is constituted, for example, by a pair of transport rollers provided slightly above the transport path, wherein the vertical movement of one transport roller is fixed, and the other transport roller is fixed. Rollers are movably arranged for vertical movement. In this state, when the rigid and thick stencil printing plate (heat-sensitive member) reaches the pair of transport rollers, the stencil printing plate "straights" while pushing down the other transport roller. On the other hand, when the flexible and thin thermal label reaches the pair of transport rollers, the height position of the other transport roller hardly changes. Therefore, the thermal label is transported "upward" according to the original arrangement of the pair of transport rollers.
