かかる欠点を除去したものでその目的は第1に活字輪体
を用いた回転ローラ印字方式を可能にすることにある。That is, a type wheel spindle 1 having a plurality of spline grooves that selectively rotates, stands still, and returns to rotation, and is disposed on the axis and synchronously engages with the type wheelset 1 as appropriate by electric signals to selectively rotate, stand still, and rotate back. Any typeface 2-1 of typeface 2 and typeface 2
It is constituted by a printing lever body 3 that presses and prints. The printing shaft 1 is selectively rotated, stopped, and rotated back by a Geneva gear (not shown), and when the printing shaft 1 is stationary, the printing lever body 3 presses and prints on an arbitrary printing surface 2-1 of the printing wheel body 2. In this system, the type roller shaft 1 is held stationary by a geneva stop or the like, but the type roller body 2 is synchronized with the spline groove of the type roller shaft 1 by means of selective engagement means such as a type roller claw 2-2 and a type roller spring 2-3. Becomes still. For this reason, the first
However, it has a serious drawback in that it is impossible to apply rotational torque to the type wheel body 2 during pressure printing by the pressure printing means. That is, a rotating roller printing method that generates high printing pressure with low load torque cannot be used as a pressure printing method. Second, if the type wheel claws 2-2 of the type body 2 do not fit completely into the spline grooves of the type body 1, the type faces 2-1 of each type body 2 may be misaligned, resulting in uneven printing lines. Not only does this result in poor print alignment, but also print characters may be missing. Furthermore, there is a major problem in that the printing surface 2 is unstable, which causes the printed surface to become double and cause stains. Thirdly, a mechanism such as a Geneva stop is required to keep the type axis 1 stationary, which requires very severe part processing accuracy. This not only increases the cost of parts, but also has the drawback of lacking reliability against changes in temperature. The present invention eliminates such drawbacks, and its first purpose is to enable a rotating roller printing system using a type wheel.

ある。The second objective is to eliminate problems such as poor line alignment, missing printed characters, and smeared printed characters caused by unevenness of printed letters during pressure printing. Thirdly, there is no need for a highly accurate Geneva stop mechanism and there is no reduction in reliability due to temperature changes. The present invention will be described in detail below based on Examples. In FIG. 2, there is a typeface shaft regulating cam 11-2 formed at one end of a spline shaft 11-1 having a spline groove on its circumference and having at least one shaft regulating groove 11-3 on a part of the circumference. There is a type wheel set 11 having a.

大きな効果を提供するものである。The printing shaft 11 is rotated by a drive mechanism (not shown) for selection, stopping, and return. A type wheel 12 is arranged on the type axis 11. On the circumference of the type ring 12, there is a character surface 1.
2-1 and type wheel regulating cam grooves 12-2 are provided alternately. Further, a type roller claw 13 is attached to the end face of the type ring 12 in a state where it is biased by a type ring spring 14. 1 in the diagram
Reference numeral 5 denotes a selection lever which is actuated by an electric signal and selectively engages the type lever 13 with the spline shaft 11-1 of the type axis 11. The crankshaft 17 is rotated by a drive device (not shown), and the printing roller 6, which is mounted eccentrically, is operated according to a rotation outer circumferential locus 16-1.
The crankshaft 17 is synchronized with the type wheel shaft 11, and is set so that when the type wheel shaft 11 is stationary, the printing roller 6 engages with any character surface 12-1 of the type wheel 12 to perform pressure printing. In the figure, reference numeral 18 denotes a type wheel alignment plate, which is biased clockwise in the drawing by the alignment plate return mechanism provided between the rotary shaft 19 and the alignment plate drive cam 21. Type wheel alignment plate 18
The type wheel shaft actuating portion 18-1 and the type wheel regulating cam groove 1 are engaged with the shaft regulating grooves 11-3 of the type wheel regulating cam 11-2.
A type rotation portion 18-2 is provided which engages and operates with 2-2. The type alignment plate 18 is rotated to the rotating shaft 19 by the push cam portion 21-1 of the alignment plate drive cam 21 when the type axis 11 is stationary.
When it is rotated around
The shaft regulating groove 11-3 engages with the type wheel shaft regulating cam 11-2, and then the type rotation section 18-2 engages with the type wheel shaft regulating cam 11-2.
The shape is set so that it engages with -2. In addition, the type wheel alignment plate 18 is provided with a forced return actuating part 18-3, and if the alignment plate return spring 20 does not return the type, the type wheel alignment plate 18 engages with the forced return cam part 21-2 of the alignment plate drive cam 21 and returns to the original state. It is set to do so. In this example configured in this manner, when the selection lever 15 is actuated in response to an arbitrary electric signal during the selective rotation of the type mechanism shaft 11, the type mechanism claw 13 and the spline shafts 11-1 engage, and the type mechanism 12 is activated. Type theory axis 11
Rotates synchronously with. At the same time as the type wheel shaft 11 comes to rest with the type wheels 12 selectively rotated in this way, the type wheel alignment plate 18 moves to the pushing cam portion 2 of the alignment plate drive cam 21.
1-1, first, the type wheel shaft actuating portion 18-1 engages with the rat regulating grooves 1-1-3 of the type-type wheel regulating cams 1-1-2, and corrects and rotates the type wheel shaft 11 to regulate it. At the same time, when the type wheel 12 is also corrected, the type wheel actuator 18-2 fits into the type type restriction cam groove 12-2 and rotates the type wheel 12 for supplementary correction to align it in regulation (as shown by the two-dot chain line in the figure). Type theory 1
2 are regulated and aligned by the type alignment plate 18', the printing roller 16 driven by the crankshaft 17 presses and prints on any character surface 12-1. Then, while the printing roller 16 and the character surface 12-1 are in contact with each other, the printing wheel alignment plate 18, which regulates and aligns the printing type 12, finishes printing, that is, the printing roller 16
Immediately after the character surface i2-1 is released, the alignment plate return spring 201
Therefore, if the spring force does not allow for return, the forced return cam portion 21-2 of the alignment drive cam 21 causes the return. (
Indicated by a solid line in the figure. ) When the type alignment plate 18 returns, the type axis 11 rotates again together with the type wheel 12, and the selection lever 15, which has returned at this time, engages the type mechanism pawl 13, and the type wheel pawl 13 and spline shaft 11. When the engagement is released, the typography 12 returns to the standby state (indicated by a solid line in the figure). In this way, the type wheels 12 are sequentially returned to the standby state, and selective printing is completed. The present invention completely achieves the above-mentioned purpose by correcting the rotation of the type wheel axis and the type itself during printing using a single component called the type wheel alignment plate, and thereby solves the problems of the conventional printing method and type. It is also possible to separate the relationship with the logic selection method, and the scope of its application is immeasurable, not only in the one-rotation clutch method type selection method and the printing method using the printing roller according to this example. Furthermore, the present invention provides significant effects in terms of cost, quality, and reliability of printing devices.
