DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows the structure of this electronic stamp. A dial 1 for selecting input characters is provided on the upper surface of the housing 4 of the electronic stamp, and the circumference of the dial 1 is hiragana,
Letters, numbers, symbols, etc. are printed.
Further, at the center of the dial 1, a button 1a for confirming the character selected by rotating the dial 1 is formed.

On the upper right side of the dial 1, a conversion key for converting the hiragana selected by the dial 1 or the like into kanji, a shift key for selecting uppercase or lowercase letters, a cursor movement key for moving the cursor, a layout or a format is changed. The input unit 2 is provided with various function keys for winding, a roll paper winding key for winding the heat-sensitive stencil sheet 8, a power switch and the like.

Below the input unit 2, a display unit 3 for displaying dialed characters, formats, messages and the like is arranged.
It is composed of a liquid crystal display panel.

The housing 4 having the above-mentioned members mounted on its upper surface is made of, for example, a resin or the like, and is formed in a shape that covers the chassis 5 from above, that is, a shape in which the bottom surface of the substantially hexahedron is opened. Has been done. Then, by a well-known method (not shown), it is assembled so as to be movable relative to the chassis 5 in the vertical direction, and is assembled so as to move integrally with the chassis 5 in the horizontal direction.

As shown in FIG. 1, the chassis 5 is formed in a substantially U-shape having three side walls 5a, 5b, 5c. Further, inside the housing 4, a locking piece 6 is attached to the tip.
The ink pad holder 6 having a is assembled integrally with the housing 4. The ink pad 7 is detachably attached to the locking piece 6a of the ink pad holder 6 from the side of the chassis 5 without the side wall, that is, from the lower left direction in the drawing.

Therefore, when the housing 4 is pushed from above, the housing 4 and the ink pad 7 move integrally downward with respect to the chassis 5 in the direction indicated by the arrow 21.

Further, on the side wall 5b of the chassis 5, a raw paper supply spool 10, a raw paper winding spool 9, and a platen 13 are rotatably supported.

The thermal head 12 is for selectively perforating the heat-sensitive stencil sheet 8 by heat melting, and the chassis 5
It is assembled so as to be swingable about a shaft 19 attached to the side wall 5a. Usually, the heat-generating end of the heat-sensitive stencil sheet 8 is supplied to the platen 13 from the stencil sheet supply spool 10 by a known means (not shown).
It is pressed against.

Inside the chassis 5, there is disposed a heat-sensitive stencil sheet 8 which is supplied from a sheet-paper supply spool 10 by a sheet-paper winding motor 11 and a drive mechanism (not shown) and is wound up on a sheet-paper winding spool 9.

The heat-sensitive stencil sheet 8 has a thermal head 12
And the platen 13 and the base paper guide roller 1
The heat sensitive stencil sheet 8 is guided by the sheets 7 and 18 so that the printing surface of the heat-sensitive stencil sheet 8 is positioned under the ink sheet 7, and is wound on the stencil sheet winding spool 9 in a fixed amount.

On the other hand, as described above, the release lever 14, which is swingably assembled to the chassis 5, has a thermal head 12 and a platen 13 which are usually in close contact with each other with the heat-sensitive stencil sheet 8 sandwiched therebetween. This facilitates replacement of the heat-sensitive stencil sheet 8 after release.

Further, inside the chassis 5, the timing belt 3 is attached to both ends of the masking sheet 36.
7 is mounted by a belt drive shaft 33, belt guide shafts 31 and 32, and a belt guide roller 34. The belt guide shaft 31 is concentrically and rotatably supported by the base paper guide roller 17. Further, the masking sheet drive motor 35 sends a masking sheet 36 by transmitting a rotational force to the belt drive shaft 33 by a drive mechanism (not shown).

Next, a method of using the electronic stamp thus constructed will be described.

In order to create a stamp face in a new format, the heat-sensitive stencil sheet 8 is pressed out by the heating element of the thermal head 12 and the platen 13 while the platen is rotated and sent out. At this time, the thermal head 12
The heating element selectively heats up in accordance with the characters and layout input through the input section 2, and heat-punches the heat-sensitive stencil sheet 8. The sent heat-sensitive stencil sheet 8 is wound up by the sheet-paper winding spool 9 and stopped at a position right below the ink pad 7.

At this time, the masking sheet 36 is sent out in a state in which only the newly formed stamp surface portion is opened.

Next, printing is performed with the ink pad 7 as described above.
The ink impregnated in the ink pad 7 passes through the holes punched in the heat-sensitive stencil sheet 8 and is applied onto the printing surface by pressing the housing 4 that operates integrally with.

2 and 3 show the structure of the masking sheet 36 portion. FIG. 2 shows a state in which the masking sheet 36 is opened over the entire printing area. When the belt drive shaft 33 is rotated in the direction of arrow A from this state, the entire printing surface area is masked as shown in FIG. In practice, the control means drives the masking sheet drive motor 35 to move the position of the masking sheet in accordance with the size of the stamp surface in the mask range shown in FIGS.

FIG. 4 shows an example of a stamp surface having a maximum stamp surface size. In this figure, the hatched portion is the masking sheet 36. Since this figure is a view of this machine from the printing surface side, the characters are mirror images.

FIG. 5 shows a state in which a character newly input from the stamp face of FIG. 4 has been punched. As can be seen here, a part of the stamp surface previously created in FIG. 4 remains, and the newly created stamp surface is positioned rightward as viewed from the stamp surface side.

If the masking sheet 36 of the present invention is used here,
Without it, it is easy to understand that the newly perforated stencil sheet needs to have the same size as the maximum stamp surface, and the stencil sheet is consumed about twice the required size.

The present invention is not limited to the embodiments described in detail above, and various modifications can be made without departing from the spirit of the invention. For example, the masking sheet 36 may be fed out by a user's hand and rewound without being fed by a motor.

[0030]

As is clear from the above description,
According to the present invention, since the imprinting range can be changed according to the size of the created stamp surface, the stencil sheet can be used effectively and wasteful consumption can be eliminated.
