Description

[Detailed description of the invention] Unexploded FJAa, Timestamp, numbering etc.
It relates to a beat device suitable for use in printing machines such as.

Conventional Libby fclm used in printing machines such as time stamps and number rings uses multiple ratchet wheels that are arbitrarily set equally divided rL7, and selects the ratchet ring as appropriate. Because it was designed to obtain arbitrary number of beats and beats by
In order to obtain mt, it was necessary to install a larger number of ratchet wheels. However, as the number of repeats increases, the width becomes wider and the repeat selection structure becomes more complicated, resulting in an increase in the overall size of the device.In addition, the operation for selecting the number of repeats becomes extremely difficult. Due to this problem, the number of repeats is limited to four ratchet rings at most, and sometimes the desired number of repeats cannot be obtained.

This is a simple example of i, rR, in which a repeat case 2t is attached to the upper case 1 of the stang, and the circumferential surface is arbitrarily set and divided into equal parts on the main shaft 3 horizontally suspended on this case 2, for example, as shown in Fig. 3. ``L7'c Attach all multiple ratchet wheels 4, move the case 2 in the axial direction, set any ratchet wheel 4, and set the ratchet pawl 50 in the rotation range, and repeat the rotation by pressing the upper case 1. When the pawl 5 engages with the teeth 4a of the ratchet wheel 4, the type 6 does not advance all the way, but the ratchet wheel 4t1 tooth is advanced and repeats. When the repeat pawl 5 falls into the deep groove 411C of the ratchet wheel 4, the push lever 7 moves the type feed pawl 8. The mechanism is such that the type is fed 6t by pressing the actuating lever 9. Therefore, when it is desired to obtain a large number of repeats, a large number of ratchet wheels 4 are required, and the above-mentioned intermittent setting occurs. Therefore, in reality, with a repeat device of this structure, only three to four types of repeat times can be obtained.

In view of the above-mentioned points of the present invention, one repeat cam can perform a large number of repeat times d of, for example, 10 or more types.
