In the direction in which 8 overlaps arm rods 7, 7, in other words, link 8
, 8 are urged downward, so that the print roller 9 and the ink roller 10 remain in contact with the ink plate 11 that has absorbed ink.

When printing, when the bundle 5 is rotated or swung forward, the printing roller 9 and the ink roller 10 are moved or slid forward while being pressed against the ink plate 11 as the arm rods 7, 7 are tilted. do.

When the printing roller 9 and the ink roller 10 move or slide on the ink plate 11 and reach the bending part 12, the rollers 9a, 9a, which are coaxial with the printing roller 9 and provided on the outside of the links 8, 8, are supported. It rolls along oblique grooves 2a, 2a provided in the frames 2, 2 and guide pieces 2b, 2b fixed to the supporting frames 2, 2 so as to be continuous therewith, and assists in guiding the advance of the printing roller 9.

In front of the ink plate 11, there is a gate-shaped card holder 14 for receiving a printed card A covered with mimeograph paper, and a presser spring piece for pressing the printed card A placed in the holder 14 from above on both sides of the holder. 15, 15 is provided.

The card holder 14 and the pressing spring piece 15.15 are the first
As shown in the figure, both are attached to a support plate 13 whose base end is freely supported on the rotational main shaft 3 described above.

Suppression pieces 16.16 are integrally provided on both sides of the base end of the support plate 13, and extensions of the base ends of the push spring pieces 15.15 are bent to form elastic pieces 15a, 15a. It is.

These elastic pieces 15a, 15a are in contact with fixed members such as the supporting frames 2, 2, and are used to bring the support plate 13 and card holder 14 into close contact with the printing paper inserted below them during printing. However, under normal conditions, the restraining piece 16 of the support plate 13
．． 16 is adapted to abut against the pair of arm rods 7, 7, and the support plate 13 and card holder 14 are connected to the elastic pieces 15a,
15a (FIG. 1), and a gap is formed between these members 13 and 14 and the upper surface of the base 1 through which printing paper can be inserted.

As described above, after the printing roller 9 reaches the bent portion at the tip of the ink plate 11, the bundle 5 continues to swing, and the printing roller 9 is removed from the ink plate 11, and the subsequent ink roller 10 is also moved immediately after that. The printed card A is supported by the card holder 14 and the spring piece 15 in front of it (separated from the ink plate 11).
The upper part is rolled, and characters, etc. are printed on the printing paper placed below it. At this time, the links 8, 8 are held in place by the spring 23 to prevent the printing roller 9 from extending forward. , armrest against 23 7. This is achieved by acting to open the valve.

Once printing has been completed in this manner, the bundle 5 can be rotated rearward to return to the state shown, whereby the link 8° 8, the support plate 13 and the card receiver 14 are supported by the elasticity of the torsion springs 23, 23, respectively. It is returned to its original state by force and by pressing the restraining pieces 16, 16 by the arm rods 7,7.

At the rear of the base 1 of the manual address printing machine as described above, a frame 17 that supports the roll paper B has pins 17a.

It is attached with 17 a.

The roll paper B is a continuous paper, and is generally separated from a mount and tags, labels, etc. attached at appropriate intervals to the mount.

The traveling direction of the rolled paper B is regulated by guide pieces 18 and 18 provided on both sides of the base frame 17, and the above-mentioned printing mechanism, that is, the support plate 13 and It is inserted under the card holder 14 and pulled out from the front of the base 1.

This feeding of the roll paper B is performed manually in the illustrated printing machine.
