CONSTITUTION:When a printer is assembled as an R type, a type wheel 24 is set between seat plates 1, 2 and a gear shaft 19 is attached to an attaching hole 22R for the R type while a cooperation gear 20 is meshed with the outer gear 6B of a main gear 6 and the attachment position of a feed gear 21 is adjusted to bring said gear 21 into engagement with a type gear 26. In the printer assembled into the R type as mentioned above, when a feed pawl 13 sends the main gear 6 to a clockwise direction by the revolution of a revolving lever 12, a main shaft 4 rotates to perform the hand movement of a clock and the cooperation gear 20 and the feed gear 21 are rotated to a counterclockwise direction along with the gear shaft 19. Similarly, the type wheel 24 rotates to a clockwise direction, that is, to a type arranging direction and rightward printing can be performed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printing device in which the arrangement of printed characters can be switched and set in either the left or right direction.

The type wheels are lined up in the direction in which the printing paper is inserted. There are two types: the R type, which prints to the right with respect to the insertion direction of the M8.P for printing, as shown in Figure 5, and the L type, which prints to the left as shown in Figure 6. The decision on whether to use one is entirely based on the user's preference, and students use the model they desire.

However, after purchase, the printing direction may be changed to R or L depending on circumstances, and there are cases where the wrong model is sold or purchased. However, in the printing machine with the above configuration, the feeding direction of the type wheel is set in one direction in both the R type and L type, so for example, it is possible to set the type wheel in the opposite direction. Even if you try to change the model, there is a problem that the type feed will be reversed, so you should prepare the type wheels and parts for the R type and L type in advance, and then take them back to the factory and make the change. Therefore, changing the model requires a considerable amount of time and effort, and there is also the problem of increased manufacturing costs due to the need to prepare type wheels and parts specifically for the two models.

The present invention has been developed in view of the above points, and its purpose is to easily change the printing machine to either the R type or L type on-site without replacing the type wheel or other parts. It is an object of the present invention to provide a printing device which can be modified and which can be easily manufactured and assembled by using a common type wheel and parts, and which can reduce manufacturing costs. The assembly of the type ring is configured so that it can be freely switched to either the left or right direction, and the feeding direction of this type wheel can be changed to either the left or right direction according to the direction in which the type is lined up by changing the gear engagement. Each of the above objectives is achieved by configuring the system so that it can also be changed.
