Abstract

PURPOSE:To decrease the number of components and to switch trend recording and character recording by operating a recording unit and a printing means selectively by motors through a switching driving means which selects dot or print recording. CONSTITUTION:When the switching driving means switches and operates selectively an intemittent recording means 16 for the trend recording and the printing means for character recording which are mounted on the common recording unit 8, the 1st motor 40 of the switching driving means moves the recording unit 8 laterally. The 2nd motor 41 moves the printing means 30 forth and back. The 3rd motor 43 switches the up/down motion of the intermittent recording means 30 and the up/down motion of the printing means 30 selectively through a cam mechanism 42. Consequently, the trend recording and character recording are switched and the intermittent recording and printing operation are performed partially by one motor, so the total number of components can be decreased.

It is now possible to move effectively against. Further, the moving piece 32 is provided with an operating piece 35 having a small cylindrical projection 35a. This actuating piece 35 is pressed by the circumferential surface of a push-out cam 37 provided on a rotating shaft 36 passing between both side plates 8a, 8a of the recording unit 8, and the receiver moves the member 31 along the guide bins 29, 29. The plotter ben 30 is slid in a direction perpendicular to the drum 5 (mitt direction).

Note that the extrusion cam 37 has a recess 37a formed therein as shown in FIGS. 4 and 5. The small protrusion is located in this recess 37a when the dotting means is activated, and in this state the extrusion cam 37 is prevented from rotating counterclockwise.

is driven, and the recording unit 8 moves along the main shaft 9 to a predetermined position on the recording paper 6 and stops (the state shown in FIG. 4(a)). Subsequently, the third motor 43 is driven, and the main shaft 9 rotates in the direction of the arrow to drop the dotting element 16 to make dots on the recording paper 6 (the state shown in FIG. 4(b)). Furthermore, when the next human power signal is input, the first motor 40 moves the recording unit 8 to the next predetermined position on the recording paper 6, while the third motor 43 further rotates the main shaft 9. The color to be dotted is changed by rotating the dot head 16 and ink drum 18. Then, when the recording unit 8 stops at the predetermined position, dots are recorded on the recording paper 6. below,
The above-described operation is performed every time an input signal is input, and trends for the number of channels of human input signals are recorded on the recording paper 6.

Next, when operating the plotter ben 30, which serves as a printing means, to record characters indicating the measured values on the recording paper 6, the first motor 40 is driven, and the recording unit 8 is driven by the main shaft 9.
It moves along to a predetermined position on the recording paper 6 and stops (
FIG. 4(a) state). Subsequently, the main shaft 9 is reversed in the direction of arrow B by the third motor 43, and the plotter bench 3
o is raised, and the push-out cam 37 is further rotated by the second motor 41 to push out the plotter ben 3° to a predetermined writing position on the recording paper 6 (Fig. 5<a>).
condition). Next, the main shaft 9 is rotated in the direction of arrow B by the third motor 43 to lower the plotter ben 30 onto the recording paper 6 (the state shown in FIG. 5(b)). Then, the plotter ben 30 is alternately moved in the direction of the main shaft 9 (X direction) and in the direction perpendicular to the drum 5 (Y direction) by the first motor 40 and the second motor 41 to print the character on the recording paper 6. Record. In addition, if the continuity of lines recorded during this period is interrupted, the main shaft 9 is rotated forward in the direction of arrow A by the third motor 43 to
0 is raised again and the recording unit 8 is moved to the next predetermined position on the recording paper 6 by the first motor 40, and then the measurement value is displayed on the recording paper 6 by repeating the above-mentioned operation. Recording of the desired character is performed.

[Effects of the Invention] As explained above, according to the recording device of the present invention, trend recording by the dot means and character recording by the printing means can be arbitrarily switched using a simple drive mechanism mainly consisting of a motor, a cam mechanism, and a gear mechanism. It can be done efficiently. In addition, since a single motor serves as a part of the operation of the dotting means and the printing means, only three motors are required in total, which reduces the number of parts and contributes to the downsizing of the device. can do.
