Description

The present invention relates to a rotary stamp.

An endless print belt having a printing surface formed of a thermoplastic resin having countless continuous pores is stretched between the bridging members provided at the top and bottom of the print frame, and the endless print belt is rotated to obtain the required endless print belt. In the conventional rotational mark in which the print portion is positioned under the lower bridging member, the strength of the thermoplastic resin having countless continuous pores is insufficient as an endless print belt. As seen in Japanese Patent Application Publication No. 2005-205798, an endless print belt made of a laminated fabric in which a thermoplastic resin surface layer having innumerable continuous pores is reinforced with a reinforcing backing is used, but when the endless print belt is widened Even when one of the bridging members is rotated, the endless print belt may follow and rotate without rotating. For this reason, various contrivances have been made to increase the resistance between the back surface of the endless print belt and the bridging member. However, it has been difficult to accurately rotate the endless print belt.

Ri that Do and rotated by the required amount, also annular seal which among feed holes of the endless printing belt body is non-porous with a narrow portion of the side edges being disposed to melt solidifying the thermoplastic resin surface layer The belt-shaped seal portion is formed with a feed hole that is engaged with the belt engagement protrusion of the belt-hanging portion, so that the strength of the periphery of the feed hole can be increased, and the endless print belt can be As wide Square thinning is possible on top that can ensure precise rotation of the endless printing belt without idling, even when the cross member is rotated in. Further, between the non-porous belt-like seal portions on both side edges of the endless print belt main body, a widthwise narrow seal portion made non-porous by melting and solidifying the thermoplastic resin surface layer is provided at a required interval. Since the porous printing portion having innumerable continuous pores is formed on the surface of the thermoplastic resin between the narrow seal portions, the narrow seal portion serves as a bending auxiliary line during the rotation operation. Rotate with a feeling.

Next, a preferred embodiment of the present invention will be described in detail with reference to a rotation mark shown in the drawings.
1 is a printing frame for rotational marks, 2 and 3 are bridging members provided above and below the printing frame 1, 4 is a wide endless printing belt stretched between the bridging members 2 and 3, and the basic structure is the conventional rotation Although the detailed description is omitted because it is the same as the mark, the present invention is characterized by the endless print belt 4 used in the present invention and the stretching means of the bridging member that stretches the endless print belt 4. That is, the endless print belt 4 has a large number of narrow portions close to at least the side edges of the wide endless print belt main body 41 made of a laminated fabric of a thermoplastic resin surface layer 42 having innumerable continuous pores and a reinforcing backing cloth 43. A hole 44 is formed in the feeding portion 45 arranged at a required interval, and a thermoplastic resin surface layer 42 is formed on the portion between both side edges of the thermoplastic resin surface layer 42 which is the front side of the endless print belt main body 41. A narrow print portion 46 in the width direction which is melted and solidified to be non-porous is provided at a predetermined interval, and a porous print portion having innumerable continuous pores between the narrow seal portions 46 and 46. 47 is formed. Further, the feeding portion 45 close to the side edge where the feeding hole 44 is disposed in the endless printing belt main body 41 is a band-shaped seal portion whose front side is made non-porous by melting and solidifying the thermoplastic resin surface layer 42. On the other hand, the reinforcing backing cloth 43 on the back side is formed in a belt-like reinforcing layer impregnated with a thermoplastic resin.

  On the other hand, the printing frame 1 includes a gripping box-shaped outer frame 11 having an open lower end, and inner frames 12 and 12 disposed on both sides of the outer frame 11. The above-described cylindrical member as the upper bridging member 2 is pivotally supported by the support shafts at both ends thereof, and can be rotated by the operation of the rotary operation element 7 at one end, and the lower end between the inner frames 12 and 12. In the meantime, an ink storage member receiver in the shape of an inverted dish box is stretched as the lower bridging member 3 described above, and the ink storage member 5 is fitted therein. Further, near the both ends of the upper bridging member 2 is provided a belt hooking portion 6 in which a large number of belt engaging projections 61 are arranged in a gear shape. In the figure, reference numeral 8 denotes a tray for supporting such a rotation mark on the desk.
