2. Description of the Related Art Conventionally, a manuscript in which a plate image is formed on a transparent film is superimposed on a sign surface of a stamp material formed of a porous resin having continuous cells that can be impregnated with stamp ink, and light is emitted on the manuscript. Various stamp plate making apparatuses have been proposed in which light of a body is irradiated to selectively seal open cells in the stamp surface portion to form a mirror image of a stamp image on the stamp surface portion. For example, in a stamp making apparatus described in Japanese Patent Application Laid-Open No. H11-277711, the stamp making apparatus is provided on a lower surface of a stamp unit and forms a stamp on a stamp material made of porous resin. Document creation means for creating a document on a transparent film based on stamp data for forming a key, and light emitted and emitted from the document side with the document created by the document creation device facing the stamp material A light emitting lamp for irradiating the stamp unit, a size detecting means arranged in the stamp device to detect the size of the stamp unit, and a driving voltage of the light emitting lamp based on the size of the stamp unit detected via the size detecting means. And voltage control means for controlling the voltage. As a result, a portion selectively melted and solidified according to the image of the original and a portion remaining as the porous resin are formed on the stamp material formed of the porous resin. Is formed.

However, the ink jet printer head directly applies a stamp ink to a mirror image of a stamp image formed on a stamp surface of a stamp material produced by a stamp producing apparatus described in Japanese Patent Application Laid-Open No. 11-277711. When a stamp is formed by applying the stamp, it is necessary to attach the stamp to the ink jet printer head with high accuracy, and thus there is a problem that the manufacturing cost of the stamp ink applying device increases. In addition, when there is a large error in the mounting position of this stamp with respect to the ink jet printer head, when multi-color printing is performed by the ink jet printer head, the applied ink dots spread to some extent and spread on the stamped surface of the porous resin. Because of the absorption, there is a problem in that the peripheral portion of the already applied ink dot of another color and the peripheral portion of the ink dot of the predetermined color overlap and the color blurs.

Accordingly, the present invention has been made to solve the above-mentioned problems, and has been made after forming a mirror image of a stamp image.

As described in detail above, in the stamp making apparatus according to the first aspect, the stamp face of the stamp is formed of a porous resin having continuous cells that can be impregnated with the stamp ink. In addition, the stamp holds the stamp in a detachable manner, and the light source of the illuminant is attached to the document in a state where the document is fixed via a fixing member that detachably fixes the document by opposing the stamp surface of the stamp. Is irradiated to selectively seal the open cells on the stamp surface, thereby forming a mirror image of the stamp image on the stamp surface. In this state, the stamp is attached to a stamp forming apparatus provided with a holding means for detachably holding the fixing member at a predetermined position. Subsequently, after detecting the position of the image of the document via the position detecting means, the stamp forming apparatus removes the document from the fixing member via the document removing means, removes the document from the stamp surface, and discharges the ink. The stamp ink is ejected to the stamp portion based on the detection data of the position detecting means and the stamp data via the means to form a stamp. Thereby, since the position of the stamp image can be detected in a state where the document is fixed to the stamp surface of the stamp via the fixing member, after forming a mirror image of the stamp image formed on the stamp surface by light irradiation,

Further, the stamp making device makes a plate image on a transparent film based on the stamp surface data through the document forming means, and irradiates the plate-made document with the stamp surface of the stamp while irradiating light from the document side. The light is emitted through the means and irradiated with light, and the open cells in the stamp face are selectively sealed to form a mirror image of the stamp image. Subsequently, the stamp forming apparatus separates the light irradiating means from the printing material via the separating means, and detects the position of the printed image of the document facing the stamp face by the position detecting means. Then, the stamp creating device removes the original from the stamp surface via the original removing unit, and discharges the stamp ink to the stamp surface based on the detection data and the stamp data of the position detecting unit via the ink discharging unit. Create a stamp. This makes it possible to make an original image on a transparent film based on the imprint data through the original preparing means to create the original, and then to detect the position of the imprint of the original in a state where the original continuously faces the imprint portion. Therefore, after forming a mirror image of the imprint on the stamp surface by light irradiation, the position of the original can be accurately detected in a state where the stamp material and the original face each other, and the detection data and the stamp surface data can be used. By applying the stamp ink to the printing surface by the ink discharging means based on the above, it is possible to provide a stamp making apparatus capable of applying the stamp ink to the mirror image of the printing image with high accuracy and speed.

According to a third aspect of the present invention, in the stamp forming apparatus according to the first or second aspect, the original has a positioning mark drawn outside a stamp image, and the position detection is performed. The means detects the positioning mark. Accordingly, the position detecting means provides a stamp producing apparatus which can have a simple structure for detecting the positioning mark drawn outside the stamp image and can improve the detection accuracy of the positioning mark. be able to.

According to a fourth aspect of the present invention, in the stamp forming apparatus according to any one of the first to third aspects, the ink discharging means and the position detecting means are provided integrally. Accordingly, the positional relationship between the ink ejection unit and the position detection unit is fixed, so that highly accurate positioning of the ink ejection unit can be easily performed based on the detection data of the position detection unit. Further, it is possible to provide a stamp making apparatus which can apply stamp ink through the ink ejection means positioned with high precision, and can easily apply stamp ink to minute characters and patterns.

Further, in the stamp forming apparatus according to the fifth aspect, in the stamp forming apparatus according to any one of the first to fourth aspects, since the position detecting means is a light reflection type sensor, it can be easily miniaturized. It is possible to provide a stamp creation device that can be converted into a stamp.
