Embodiment approach 1

[0062] "Reference Figure 1A , Figure 1B , Figure 2A , Figure 2B , image 3 , Figure 4A , Figure 4B Explanation of the mechanical structure of the stamp forming device (thermal printer) >>

[0063] Figure 1A It is an external perspective view showing the seal forming device according to Embodiment 1 of the present invention together with the seal member holder, Figure 1B It is a perspective cross-sectional view showing the cross-sectional structure of the seal forming device on the X-Z plane (including the vertical plane in the transport direction). Figure 2A It is a schematic diagram showing the structure around the discharge port of the seal member holder of the seal forming device according to Embodiment 1, showing Figure 1B Part IIA shown (in this specification, for the sake of convenience, "II" is used as the same Figure 1B The number corresponding to the Roman numeral "2" is shown, and "V" is used as the number corresponding to the Roman numeral "5" for ...

Embodiment approach 2

[0210] As described above, the stamp forming apparatus (printer 1 ) according to Embodiment 1 can form a stamp suppressed from crushing by reducing the heat of the heating point adjacent to the non-heating point. However, as long as it is a heating point adjacent to a non-heating point, regardless of the heating point, the seal forming apparatus according to Embodiment 1 reduces the amount of heat generated. So, for example, if the reduction targets such as Figure 15A If the heating amount of the isolated heating point surrounded by non-heating points is shown, sufficient heating amount cannot be obtained. As a result, there is a problem that, for example, in an image in which non-heated spots (ink bleeding portions) are in the majority, such as an error diffusion image, the printed result is likely to be crushed by ink.

[0211] Therefore, given that the point most prone to crushing is the Figure 15B As shown, the non-heating point (isolated point) surrounded by the heati...

Abstract

A stamp face forming apparatus includes a stamp face forming part including a plurality of heating elements arranged in a direction along a surface holding a porous stamp face material that can be made non-porous by heating, and a drive circuit for controlling heat generating states of the plurality of heating elements to form a stamp face on the stamp face material; and a controller for controlling the drive circuit of the stamp face forming part by adjusting a signal to be applied to the drive circuit such that an amount of heat per dot for a dot to be heated directly adjacent to a dot to be non-heated is less than an amount of heat per dot for a dot to be heated not directly adjacent to the dot to be non-heated in image data for forming the stamp face.

Description

[0001] Cross References to Related Applications [0002] The present invention is based on and claims priority to Japanese Patent Application No. 2013-229261 filed on November 5, 2013, and Japanese Patent Application No. 2014-132827 filed on June 27, 2014, And the entire content of this original patent application is hereby incorporated by reference. technical field [0003] The present invention relates to a seal forming device and a seal forming method. The seal is formed on a seal component held by a seal component holder. Background technique [0004] The known seals in the past used porous sheets such as sponges and rubber as seal components, and ink was impregnated in the seal components in advance in order to save the man-hours of attaching ink to the seal surface each time the seal was pressed. For example, such a device has been proposed in Japanese Patent Application Laid-Open No. 10-100464. A stamp with a printing plate (print surface member) made of a porous she...
