Abstract
The present invention relates to a porous stamp assembly. The manufacturing method of the assembly comprises a first step of hermetically adhering a porous impression die member of thermoplastic resin to a front end face of a frame; a second step of fixing the die member embedded frame onto a mount that is to be in face-to-face relation with a thermal head attached to a seal carving device; a third step of putting the thermal head in contact with an upper major surface of the porous impression die member, with a resin film interposed therebetween, and moving the thermal head and the porous impression die member relative to each other; and a fourth step of removing the die member embedded frame from the mount.
Claims13
A manufacturing method of a porous stamp assembly, comprising the steps of
- hermetically adhering a porous impression die member of thermoplastic resin to a front end face of a frame, for preparing a die member embedded frame,
- fixing the die member embedded frame onto a mount that is to be in face-to-face relation with a thermal head attached to a seal carving device, for bringing an upper major surface of the mount in contact with a lower major surface of the porous impression die member,
- putting the thermal head in contact with an upper major surface of the porous impression die member, with a resin film interposed therebetween, and moving the thermal head and the porous impression die member relative to each other, for carving the upper major surface of the porous impression die member into an impression die, and
- removing the die member embedded frame from the mount, and bringing and keeping the lower major surface of the porous impression die member in contact with an ink retainer soaked with ink, for permitting a holder keeping the ink retainer therein to hold the die member embedded frame.
A manufacturing apparatus of a porous stamp assembly, comprising
- a first means hermetically adhering a porous impression die member of thermoplastic resin to a front end face of a frame, for preparing a die member embedded frame,
- a second means having a thermal head and fixing the die member embedded frame onto a mount that is to be in face-to-face relation with the thermal head, for bringing an upper major surface of the mount in contact with a lower major surface of the porous impression die member,
- a third means putting the thermal head in contact with an upper major surface of the porous impression die member, with a resin film interposed therebetween, and moving the thermal head and the porous impression die member relative to each other, for carving the upper major surface of the porous impression die member into an impression die as a stamping face, and
- a fourth means removing the die member embedded frame from the mount, and bringing and keeping the lower major surface of the porous impression die member in contact with an ink retainer soaked with ink, for permitting a holder keeping the ink retainer therein to hold the die member embedded frame.
