A transfer device for sequentially transferring a transferred image to a recording sheet such as a postcard or a notebook is known. In such a transfer device, an image of the original sheet is formed as a hole in the original sheet by irradiating a light beam, and ink is set in the recording paper through the hole, thereby recording the image of the original sheet. Transcribed on paper.

[Problems to be Solved by the Invention] However, in the above-described transfer device, since a large amount of ink cannot be applied, the transferred image is blurred when a large number of inks are transferred. Therefore, it is necessary to replenish the ink on the way, which is troublesome, and there is a problem that the hands become dirty. In addition, when the original transferred in this way is used again after a few days, the ink oozes out in the next few days, so the transfer cannot be performed immediately, and the reuse is inconvenient. There is a problem that it is troublesome.

FIG. 6 shows a circuit configuration of the thermal transfer device 1 described above. In the figure, reference numeral 12 denotes a battery stored in the battery storage chamber 6 of the apparatus main body 2. The battery 12 is connected to a high voltage generating circuit 19 via a voltage dividing resistor R ₁ , R ₂ , R ₃ and a contact _{Sa 1} interlocking with _a charging switch Sa interposed in a connection line of a constant voltage detecting circuit 18, and a flash light. The capacitor C ₁ , the relay L, the trigger circuit 20, and the discharge lamp 9 are connected. The high voltage generation circuit 19 boosts the voltage of the battery 12 to a high voltage.

But the trigger circuit 20 including a step-up transformer, the discharge lamp 9 is flash the voltage charged when the discharge switch S _b is closed to the flash capacitor C ₁ is boosted.

Next, a case where an original plate is created and transferred to a recording sheet by the thermal transfer apparatus 1 configured as described above will be described.

When preparing an original, first, the holder 3 is removed from the lower part of the apparatus main body 2 as shown in FIG. In this state, the operating levers 4 and 4 of the apparatus main body 2 are operated to push down the holding members 11 and 11 as shown in FIG. Set sheet 15. That is, when the operation button 4a of the operation lever 4 is pushed from the outside, as shown in FIG. 4, the rotation arm 4b rotates around the pin 4c in the arrow X direction, and the tip of the rotation arm 4b is held. The respective contact portions 11c of the member 11 are pushed down against the coil spring 16. Then, the holding member 11 is moved downward with the guide portions 11b, 11b at both ends thereof being guided by the guide grooves 2h, 2h of the lower case 2b, and the locking portion 11a at the lower end thereof is positioned below the light source chamber 8. It is extruded downward from the provided transparent glass 13. In this state, the original sheet 15 is inserted between the locking portion 11a of the holding member 11 and the transparent glass 13. When the pressing of the operation lever 4 is released, as shown in FIG.
Each holding member 11 is pulled up by the coil spring 16, and the locking portion 11 a at the lower end sandwiches the edge of the original sheet 15 into the concave portion 13 a provided at the edge of the transparent glass 13. As a result, the original sheet 15 is mounted on the lower surface of the transparent glass 13. After the original sheet 15 is attached in this manner, the apparatus body 2 is placed on the original 21 with the original sheet 15 down.
(See Fig. 7), and place the original sheet 15
Adhere to 21. In this case, since the holder 3 is not attached to the lower part of the apparatus main body 2, the original sheet 15 mounted below the transparent glass 13 directly contacts the original 21.
As a result, an original can be created.

Then, set the charging switch S _a provided on the upper surface of the apparatus main body 2 to the original creation position I. Then, the contact S _a1 shown in FIG. 6 is closed, charging is started to flash capacitor C _1, the voltage V ₀ increases with charging of the flash capacitor C _1, which together with the input of the constant voltage detection circuit 18 side voltages V ₁ is opened the contact L _a of the relay L becomes a predetermined value, the charging of the flash capacitor C ₁ is stopped, the light emitting diode 7 is turned on at the same time. Lighting of the light emitting diode 7 indicates that flash preparation is completed. In this state, when closing the discharge switch S _b, the voltage accumulated in the flash capacitor C ₁ is supplied to the trigger circuit 20, a high voltage is applied to the trigger electrode of the discharge lamp 9, the discharge lamp 9
Emits a strong flash.

When the discharge lamp 9 emits a flash in this manner, the light beam is transmitted to the original 21 through the transparent glass 13 provided at the lower part of the light source chamber 8 and the original sheet 15 under the light as shown in FIG. Irradiated. In this case, the original sheet 15 is a resin sheet made of a transparent polyester film or the like. The document 21 is provided with an ink image 21a on the surface (upper surface) of the document 21 by printing or copying, and is, for example, an ordinary printed matter or copied paper. And
As described above, when the light from the discharge lamp 9 irradiates the original 21, the original 21 is in close contact with the lower surface of the original sheet 15, and thus a part of the ink image 21 a on the surface of the original 21 (that is,
The carbon and the like contained in the ink are transferred to the lower surface of the upper original sheet 15 as an image 22a as shown in FIG. As a result, the original plate 22 is created.

Next, an image 22a transferred using the master 22
The case of transfer to 3 will be described. In this case, first, the reels 17, 17 around which the thermal transfer sheet 14 is wound are stored in the respective relay storage sections 3 b, 3 b of the holder 3, and the holder 3 is mounted on the lower part of the apparatus main body 2. That is, the respective ends of the thermal transfer sheet 14 are wound around the reels 17 and 17, respectively, and the intermediate thermal transfer sheet 14 is disposed below the holder 3 as shown in FIG. It is inserted from above the reel storage portions 3b, 3b through the side of the holder 3, and each shaft portion 17a of the reels 17, 17 is rotatably supported by the shaft support portions 3f. In this state, the holder 3 is made to correspond to the lower part of the apparatus main body 2, and the hooks 3c, 3c provided before and after the holder 3 are engaged with the locking recesses 2j on the apparatus main body 2 side. Thereby, the holder 3 is mounted on the lower part of the apparatus main body 2.
When the holder 3 is installed in this way, as shown in FIG. 5, the original plate 22 held on the lower surface of the transparent glass 13 of the light source chamber 8
Only the protrusion protrudes downward from the opening 3a of the holder 3, and the thermal transfer sheet 14 is stretched over the lower surface thereof. The apparatus main body 2 on which the thermal transfer sheet 14 is stretched as described above is disposed on the recording paper 23, and the thermal transfer sheet 14 is brought into close contact with the recording paper 23.
As a result, transfer to the recording paper 23 becomes possible.

In this state, when transferring to the recording paper 23,
As with the original creation described above first sets the charging switch S _a on the recording paper created position II. In this case, except that the input to the constant voltage detection circuit 18 becomes the connection portion of the resistor R ₂ and R _3, the discharge lamp 9 is the same as for the operation of all mask fabrication until the flash. That is, the voltages V ₁ and V ₂
Increases as the charging voltage V ₀ increases, and V ₁ >
Have a relationship of V _2. Therefore, when the constant voltage detecting circuit 18 is connected to the original plate forming position I, the recording paper forming position II
Operate later than if connected to In other words, than when the person in the case of setting the charging switch S _a to mask fabrication position I is set to the recording paper transfer position II, longer charging time for the flash capacitor C _1, it is charged to a high voltage You. For this reason, the flash energy of the discharge lamp 9 is larger in the case of preparing the master, and smaller in the case of transferring the recording paper.

In this way, after being charged to a high voltage flash capacitor C ₁ is to close the discharge switch S _b, a discharge lamp 9
Flash. Then, as shown in FIG. 9, the light beam is radiated to the thermal transfer sheet 14 therebelow through the original sheet 15, but its flash energy is smaller than in the case of the original preparation as described above. When the light beam irradiates the master 22 in this manner, the master 22 has an ink image 21a of the original 21 on its lower surface.
Since the image 22a in which a part of is transferred is provided,
Since the image 22a does not transmit light, and the image 22a is made of black carbon or the like having good heat absorption, the image 22a absorbs light and has heat. Since the other portions transmit light, they do not have heat. On the other hand, the lower thermal transfer sheet 14 has an overall thickness of about 3
A light reflection layer 14b made of a metal vapor-deposited layer of nickel (Ni), aluminum (Al), copper (Cu) or the like on the transparent or opaque base film 14a of polyester or the like, A configuration is such that a hot-melt ink layer 14c made of hot-melt color ink or the like is formed on the lower surface of the base film 14a. Therefore, the light transmitted through the portion of the original plate 22 other than the image 22a is applied to the heat transfer sheet 1
4 is reflected by the light reflection layer 14b, the heat transfer sheet 14 in this portion does not have heat, but since the portion of the image 22a of the original 22 has heat due to the irradiated light beam, this heat is transferred to the heat transfer sheet 14. It is transmitted to the hot-melt ink layer 14c via the 14 light-reflective layers 14b and the base film 14a, and only the hot-melt ink layer 14c in this portion is melted, and the melted portion 14d is located on the lower side as shown in FIG. It is thermally transferred to the recording paper 23. This allows
The image 22a of the original 22 is transferred to the recording paper 23 reliably and clearly. When transferring to another recording paper 23 again, one of the reels 17, 17 exposed from the holder 3 is turned with a finger or the like, and the thermal transfer sheet 14 necessary for one transfer is transferred to the original plate. The discharge lamp 9 may be flashed in the same manner as described above by pulling out and setting a new one under 22. By repeating this, any number of sheets can be transferred, and furthermore, it can be easily transferred to a recording paper bound with a note or the like.

In the above-described embodiment, the ink image 21a of the original 21 is directly transferred to the lower surface of the original sheet 15 at the time of original production. However, the present invention is not limited to this.For example, as shown in FIG. A transparent hot-melt adhesive layer 15a may be provided in advance on the lower surface of the printer, and the ink image 21a of the document 21 may be transferred to the original sheet 15 side with the hot-melt adhesive layer 15a. In this case, it is preferable that the hot-melt adhesive layer 15a does not melt much by heat.

Further, the transfer sheet 14 does not necessarily have to have the light reflection layer 14b on the upper surface of the base film 14a, and need to have the hot-melt ink layer 14c on the lower surface.For example, as shown in FIG. A heat-melted ink layer 14c may be provided on the lower surface, and as shown in FIG. 13, the base film 14a
Although a light reflection layer 14b and a hot-melt ink layer 14c may be sequentially laminated on the lower surface of the base film 14, in this case, the base film 14
As a, it is necessary to use a transparent durable film such as polyimide.

Further, the circuit configuration of the power supply for flashing the discharge lamp 9 is not limited to the method of switching the charging time as in the above-described embodiment, and for example, the flashing time may be switched.
Alternatively, two capacitors may be used and charged independently.

The transfer sheet is placed so that the light reflecting layer of the transfer sheet faces the transparent member and covers the resin sheet, and in this state, the transfer sheet is pressed onto the recording paper, and the light source lamp in the light source chamber flashes. By irradiating light rays from the resin sheet side, the hot-melt ink layer corresponding to the ink image of the resin sheet can be transferred onto the recording paper, and thereafter, one end of the transfer sheet is connected to the other end. By winding the transfer sheet from the side, the transfer sheet can be sequentially moved in the longitudinal direction, so that a new portion of the transfer sheet can be made to sequentially correspond to the resin sheet. It can be transferred to recording paper. As a result, any number of sheets can be easily transferred without soiling the hands and the like, so that the transfer workability is good and efficient, and it is easy to transfer the data to the recording paper joined with the notebook or the like. Can be. In particular, if the power supply device is provided with a circuit means for changing the flash energy of the light lamp, it is possible to more efficiently perform the preparation of the master and transfer the image to the recording paper, and to achieve a sharper image. Images can be obtained.
