[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a numbering machine, and more particularly to an improvement in an ink pad support for applying ink to a numbering ring.

[0002]

2. Description of the Related Art FIG.
As shown in FIG. 5, a support bracket 53 in which an ink pad 52 is fitted by a pivot 51 around which a coil spring 50 is wound, and a pressing piece 5
4 support the bearing pieces 59, 60 provided integrally with each other,
The coil spring 50 acts on the support fitting 53 and the holding piece 54, and the bent portion 56 of the holding piece 54 is pressed against the long hole 58 of the support arm 57 (see FIG. 6) and stopped. So the Axis,
A coil spring was required, and assembly was troublesome.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide an ink pad support which has a smaller number of parts than the conventional ink pad support, can be manufactured easily, and is inexpensive.

[0004]

The means of the present invention are as follows.

In an ink pad support for a numbering machine in which a support for an ink pad and a holding piece thereof are pivotably connected to each other, a thin elastic metal piece is bent into a broken circle,
Further, the resilient hollow pivot having the intermediate portion curved inward toward the nipple and forming a small curved portion in the intermediate portion is inserted into a circular hole formed in a bearing piece protruding from the support bracket and the holding piece. The outer curved portion of the resilient hollow pivot is brought into contact with the peripheral edge of the circular hole, and the bearing piece of the support bracket and the stop protrusion protruding from the peripheral edge of each circular hole of the bearing piece of the holding piece are attached to the bent end of the outer curved portion. Pressed structure.

[0006]

The knob 1 'of the supporting bracket 1 and the knob 3' of the holding piece 3 are pinched with fingertips, and the knobs 1 'and 3' are moved from the position (b) to the position (c) in FIG. When it is pushed in, the bearing piece 7 of the holding piece 3 rotates, and the stop projection 12 pushes the bent tip 5e of the outer curved portion 5c.
As shown by the dotted line, the holding piece 3 can be opened appropriately. When the force applied to the fingertip is released, the pressing piece 3 returns to the original position, and enters the elongated hole 58 of the support arm 57 shown in FIG.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the drawings, reference numeral 1 denotes a support fitting on which an ink pad 2 is fitted, 1 'denotes a knob thereof, 3 denotes a holding piece of the support fitting 1, and 3' denotes a knob thereof. The pressing piece 3 is composed of a rising part 3a having a right angle so as to be engaged with a long hole 58 provided in a support arm 57 of the numbering machine, and an inclined piece 3b ahead of the rising part 3a.

In the present invention, the support bracket 1 and the holding piece 3
The structure for winding the coil spring around the pivot is modified to use a resilient hollow pivot 5 having both elasticity and spring action, in which an elastic metal piece is rounded. The resilient hollow pivot 5 has a small curved portion 5a which is curved in a nipple-like shape inwardly in the middle part of the resilient hollow pivot 5,
Outer curved portions 5b and 5c are provided in the missing circular portions, and circular holes 8 are formed in left and right bearing pieces 6 and 7 protrudingly opposed to the support fitting 1 and the holding piece 3.
And the elastic hollow pivot 5 is inserted into the circular hole 8, and the bent ends 5 d and 5 e of the outer curved portions 5 b and 5 c are connected to the support fitting 1.
Of the circular hole 8 formed in the bearing piece 6 of the bearing piece 6 and the bearing piece 7 of the holding piece 3.

[0009]

According to the structure of the present invention, the conventional two pivots and winding springs need only one resilient hollow pivot 5, and the number of parts is small. The pivot penetrates through a circular hole formed in the bearing piece, and comes into pressure contact with the circular hole during operation, whereby the opening of the support bracket and the holding piece stops. Therefore, by adjusting the diameter of the circular hole, the support bracket and the holding piece can be operated to such an extent that an excessive force is not applied to the resilient hollow pivot.
