JPH1016368A - Printing body of rotary printer - Google Patents

Abstract

PROBLEM TO BE SOLVED: To increase the number of printing faces twice without the need of enlarging its rotary printing outside size, by constituting such that when rotated, at a place where a motive driving wheel turns round twice while being twisted half at the half-round twisted position of a flat belt, the printing face turns back again at the control printing position. SOLUTION: A flat belt 1 of an endless ring formed of rubber having a half-round twisted portion en route and an arrangement of various kinds of one and another side printing faces 2, 3 laying along the longitudinal direction of the flat belt 1 form a printing body 6 having recesses 4, 5 defining teeth of a rack between the one and another side printing faces 2, 3. Besides, large and small diameter pinions 9, 10 are axially supported within the upper and lower parts of a case 8 and the printing body 6 is rounded over the large and small diameter pinions 9, 10 so as to permit the toothed parts 11, 12 of the large and small diameter pinions 9, 10 and the recesses 4, 5 to be fitted with each other. When the large diameter pinion 9 is rotated, it comes back to the first printing face at the position where it turns round twice while being twisted at the half-round twisted portion of the flat belt 1, i.e., sealing can be done by arbitrarily selecting one in the one and another side printing face 3, 4.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a stamp body in a rotary stamp of a type in which a desired stamp surface is selected by rotating a stamp body by a driving wheel and a driven wheel to imprint a stamp.

[0002]

2. Description of the Related Art A known type of a stamp body of this type is of a type in which a large number of stamp faces are arranged only on one side of an endless ring-shaped flat belt having no torsion. So,
The other side has no stamped surface.

[0003]

However, in the above-described prior art, the rotary stamp printing body cannot provide a printing surface on the other surface side, so that the total number of printing surfaces is small. If the number is increased, the outer shape of the entire rotation mark becomes large.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a novel rotary stamp body which can be implemented even if the total number of stamp surfaces is doubled and the outer shape of the entire rotary stamp is hardly increased. It is.

[0005]

In order to achieve the above object, a stamp for a rotary mark according to the present invention comprises a flat belt 1 having an endless ring shape with a half-turn twist in the middle, and a flat belt 1 having an endless ring shape.
On one side along the longitudinal direction thereof, and a plurality of one-side stamped surfaces 2 arranged along the longitudinal direction on the other surface, and a plurality of other stamped surfaces 3 arranged on the other surface along the longitudinal direction. .

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the embodiment shown in the figure, a flat belt 1 is formed into an endless ring shape by twisting a half turn with rubber in the middle.
Numerous types of one-side stamped surfaces 2 are arranged on one side of the flat belt 1 along its longitudinal direction, and many other-side stamped surfaces 3 are also arranged on the other surface along the longitudinal direction. As a result, a stamp body 6 having recesses 4 and 5 having a tooth shape of a rack between the one-side stamping surfaces 2 and the other-side stamping surfaces 3 is obtained. A long and oblong flat case 8 having a long diameter 7 is formed, and a large-diameter pinion 9 is supported in the upper part of the case 8 and a small-diameter pinion 10 is similarly supported in the lower part thereof. On the other hand, the stamp body 6 is wrapped around the teeth portions 11 and 12 of the pinions 9 and 10 and the recesses 4 and 5 are engaged with each other, and the central shaft portion 13 of the large-diameter pinion 9 is moved out of the case 8. Extrude and fix the rotary operation knob 14 to the extruded end Shall apply those were, the knob 14
Is turned by hand to allow one stamp face to protrude outside of the stamp face exit 7.

In the figure, reference numeral 16 denotes a tooth 12 of the small-diameter pinion 10.
2 shows a pressing spring 17 type stopper which enters and exits the rotation locus of the pinion 10 to prevent the pinion 10 from idling.

[0008]

According to the present invention, the rotary mark is rotated around a driving wheel (corresponding to a large-diameter pinion in the embodiment) and a driven wheel (corresponding to a small-diameter pinion in the embodiment). In this case, the flat belt 1 returns to the first stamped surface after making two turns while being half-twisted at a twisted portion (indicated by reference numeral 19 in the figure) of the flat belt 1, that is, the one-side stamped surface 2 and It is possible to arbitrarily select and seal one of the other side-side stamped surfaces 3.

[0009]

According to the present invention, it is possible to provide a stamp body in which the number of stamp faces is doubled, and it is not necessary to enlarge the outer shape of the rotary stamp.
