In addition, in the explanation of the drawings of both hands, the same elements are indicated by the same reference numerals. A capstan 2 is attached to the rotating shaft of the tanabata 1, which is prevented from rotating by the step pulse, and the capstan 2 is equipped with a steel bell 1-3 or 56. Steel bell l-3 is fixed by bell 1-volk 4, II Bustan 2
Change the rotational motion of to linear motion P1! Zuru. this? The one-line motion is transmitted to the carriage 5 by means of a guide bin 7, thereby causing the -1 goat 5 to make a t1 backward motion along the rail 6.

The carriage 5 is driven in this direction. However, conventionally, since there is a fitting gap between the carriage 5 and the rail 6, when the key 1 ridge 5 moves linearly in the direction of the rail 6, it resonates and the key 17 ridge 5 stops. The vibration state may continue. For this reason, there was a drawback that the head 8 continued to output data and that old data could not be stored.

The spool heel 1-3 has an approximately /-shape. As a result, the rotational motion of the kitobskun 2 is converted into a linear motion, and the rail 6 is moved by a distance in the direction h perpendicular to the axis of the rail 6.

Assuming that the distance from the center to the center is B, the rotational moment 1 will be increased by 71 as shown by the arrow M in the figure. Konoshi-

きる。Also, for the rail support member 5 of the key 17, the distance between the centers of the members 9a and 9b is set to 1, and the drag force of the rail support members 9a and 9b against the rail 6 is set to N and 1. IN

。The coefficient of friction between the rail 6 and the rail support parts u 9 a, 9 b is expressed as μ and 411 generated by the steel bell i-3.
If the frictional force between the rail 5 and the rail 6 is [- and 4, then (1

りするような欠点は無り４する。Therefore, according to equation (1), when there is a jilt line movement, a drag force of N 3/[ is always exerted between the rail 6 and the rail support members 9a and 9b, so the movement -1-Torishi 5 resonates and stops for 11m, and the vibration state becomes dark blue.Continuation (there is no such thing as J-ru.Therefore, it is by head 8)'-Evening readout, it seems that it is not possible to guess. There are no major drawbacks.

Since the force of F = M B / L is applied between b, the time required for the carriage 5 to come to a standstill (sen milling time) is short, and therefore the data There is also the advantage that 71 things can be read quickly, including -1.
