Abstract

PURPOSE:To contrive a more uniform corrected surface and easier correction, by a method wherein a film provided with a heat-fusible ink in discontinuous patterns is placed at a window provided in a lower surface of a casing, and the ink is melted by a heating means to correct an image on a document. CONSTITUTION:With a knob 7b press down so that the window 1a is located on the part to be corrected of the document, a movable member 7 is depressed, whereby a pawl 12 is separated from a rachet wheel 9. By pressing the member 7, the ink 2a applied to the film 2 is extruded to the exterior of the window 1. The ink 2a is melted, and is transferred onto the part to be corrected of the document. With the knob 7b released after correction, the member 7 is returned upward. At this time, a gear 11 is driven to rotate counterclockwise, a one-way clutch is operated to rotate the ratchet wheel 9 counterclockwise, and the holes 2b in the film 2 are sequentially fitted to the teeth of the sprocket 8, whereby the feeding of the film is started. The rotation of the sprocket 8 is stopped after one-tooth amount of feeding, whereby the movement of the film is stopped.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a calligraphy and drawing correction device using thermal transfer.

Conventional technology In the past, when making partial corrections to the content written on documents such as photocopies, the practice was to apply so-called correction fluid to the corrected areas or to scrape off the corrected areas using a knife. .

Problems to be Solved by the Invention However, with the conventional methods described above, there are problems such as the correction is time consuming and the surface of the corrected area becomes rough, making it difficult to perform new recording. Ta.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, it is an object of the present invention to provide a calligraphy and drawing correction device using thermal transfer that can correct a portion of the content written on a document with ease and with a uniform surface.

Means for Solving the Problems In order to achieve the above object, the present invention provides the following steps according to the distance between the casing having a window hole formed on the lower surface and the heat-melting ink provided intermittently on the film. A means for conveying the film intermittently so that the film can be seen through the window hole on the lower surface of the casing, a means for heating the film that is seen through the window hole on the lower surface of the casing, and means for pressing the film seen through the window hole on the lower surface to the outside of the casing.

For example, when there is a portion of the document that needs to be corrected, the film is transported by the transport means to the window hole on the lower surface of the casing.

The film that has reached the window hole is pressed against the outside of the casing by a pressing means, and the hot-melt ink on the film that has entered the window hole is transferred to the portion of the document that needs to be corrected. Documents will be corrected.

Embodiment FIG. 1 is a schematic sectional view of an embodiment of the present invention, and FIG.
FIG. 3 is a schematic bottom view of the device shown in the figure, and FIG. 3 is a schematic perspective view of the device.

In FIGS. 1 to 3, window holes 1a and 1b are formed in the lower and side surfaces of the case 1, respectively.

The casing 1 has a supply roller 3 around which a film 2 is coated intermittently with heat-melting ink 2a and has intermittent holes 2b formed on the side thereof, and a take-up roller that winds the film 2. It has 24 built-in.

The film 2 is intermittently conveyed above the window hole 1a according to the intermittent length of the ink 2a on the film 2.
a conveying means 5 for allowing the film 2 to be seen through the window hole 1a, a heat generating circuit 6 as a means for heating the film 2 seen through the window hole 1a, and a means for pressing the film 2 through the window hole 1a to the outside of the casing. A movable member 7 is provided.

The conveying means 5 includes a sprocket 8 that sequentially fits into the hole 2b of the film 2 and conveys the film 2, a ratchet gear 9 provided on the shaft of the sprocket 8, and a belt 1o connected to the sprocket 8 and the take-up roller 4. and a gear 11 equipped with a one-way clutch that transmits only counterclockwise driving force. The distance between adjacent teeth of the ratchet gear 9 is equal to the discontinuous length of the ink (2a) applied to the film 2. The pawl 12, which together with this ratchet gear constitutes the ratchet device 12,
It is provided near the ratchet gear 9. The fulcrum 12a of the claw 12 is fixed to the casing 1, and the claw 12 is fixed to the fulcrum 12a.
It is rotatable around the center. A spring 13 is attached to one end of the pawl 12, and the other end of this spring 13 is attached to the fixed portion 1C. Further, a wire 14 is tied to the other end of the pawl 12, and the other end of the wire 14 is connected to the movable member 7, with the intermediate portion in contact with the fixed portion 1C.

The upper part of the movable member 7 is attached to the casing 1 via a spring (not shown). Further, the movable member 7 has a rack 7a on its upper part for driving the gear 11, and a knob 7b exposed through a window hole 1b on its side.

The heat generation circuit 6 is provided inside the movable member 7 and includes a switch 6a, a resistor eb, a power source 60, and the like. When the movable member 7 moves downward, the switch 6a is closed by the fixed part 1d, and the resistor 6b is configured to generate heat.

Next, the operation of this device will be explained.

When the window 1a of this device is placed over the area to be corrected in the document and the knob 7b is pushed down, the state shown in FIG. 4 is obtained. That is, as the movable member 7 is pushed down, the pawl 12 is pulled by the wire 13 and separated from the ratchet gear 9. At this time, the gear 11 of the rack 7a is rotated clockwise, but this driving force is not transmitted to the belt 1o due to the action of the one-way clutch, and the belt 10 does not move. Further, by the suppression of the movable member 7, the ink 2a applied to the film 2 at the relevant portion is made to protrude outside the window hole 1a. At the same time, switch 6a is closed and resistor 6
b generates heat. The ink 2a is melted by this heat and is transferred to the portion of the document to be corrected, thereby making the correction at that portion.

When the correction is completed and the knob 7b is released, the movable member 7 is returned upward by a spring (not shown). - At this time, the gear 11 is rotated counterclockwise due to the upward movement of the rack 7a, and the one-way clutch is activated.
The driving force rotates the ratchet gear 9 counterclockwise via the bell 10, the holes 2b of the film 2 are sequentially fitted into the teeth of the sprocket 8, and the film 2 begins to be conveyed.

Then, the spring 13 causes the pawl 12 to hit the ratchet gear 9, and when it has been advanced by one tooth, the rotation of the ratchet gear 9, that is, the rotation of the sprocket 8, is stopped, and the movement of the film is stopped. . In this way, the film 2 is fed intermittently. Then, new ink 2a is transferred to the window hole 1a, and the state shown in FIG. 1 is again achieved.

In addition, in this example, the case where correction is made in a fixed shape has been explained, but by creating a structure in which the size of the window hole can be changed and restricting ink transfer with the window hole, it is possible to make corrections in any size. You can also do this.

Effects of the Invention According to the present invention, a film intermittently provided with heat-melting ink is shown through the window hole on the lower surface of the case, and the ink is melted by heating means to correct the calligraphy and drawings on the document. The surface can be made uniform and corrections can be easily made. Also, after modification,
Since the film is intermittently transported by the transport means according to the length of the ink interruption, and the film with new ink is exposed through the window hole, corrections can be made without any hassle.
