In addition, the plotter pen 30 is installed in the recording unit 8 compactly by being arranged almost parallel to the lower part of the dot pen 16, and there is no need to provide extra space on the recording paper 6. It is now possible to move effectively. Further, the movable piece 32 is provided with an actuating 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 moves the receiving member 31 along the guide pins 29, 29. and slide the printer pen 30 onto the drum 5.
It is moved in the direction perpendicular to (front-back direction).

Further, a sensor 38 detects a reference position of movement of the recording unit 8 in the main axis 9 direction (lateral direction).
is provided on the side plate 1a of the chassis 1, and this detection is performed by an operating protrusion 39 provided on the recording unit 8.

Next, the switching drive means is a first motor 40 that moves the recording unit 8 in the direction of the main shaft 9 (lateral direction).
Then, the printer pen 30, which serves as a printing means, intersects with the drum 5 via the gear train 55 (perpendicular in the embodiment).
A second motor 4 that moves in the direction of
1, a cam mechanism 42 controls the vertical movement of the dotting element 16 constituting the dotting means and the vertical movement of the plotter pen 30.
A third motor 43 is provided to selectively operate the motor. These first, second, and third motors 40,
Reference numerals 41 and 43 are, for example, pulse motors whose pulse drive is controlled by a microprocessor (not shown). The first motor 40 is disposed on the back plate 1b of the chassis 1, and the rotating shaft pulley 40a of the first motor 40 and the feed rollers 12, 12 on both side plates 1a, 1a of the chassis 1 are arranged on the back plate 1b of the chassis 1.
The recording unit 8 is slid in the direction of the main shaft 9 via a wire 13 stretched between them. Also,
The second motor 41 is disposed at the upper back corner of the side plate 1a, and rotates a rotating shaft 36 through which the extrusion cam 37 passes through the printer pen 3.
0 is moved in a direction intersecting the drum 5.
Furthermore, the third motor 43 is fixed to a mounting plate 44 and is arranged on the side plate 1a of the chassis 1 via a gear mechanism constituted by a plurality of gears 45. The driving force of this third motor 43 is transmitted through the gear 45 of the gear mechanism to rotate the main shaft 9 on the one hand, and to drive one disc of the clutch plate 47 fixed to the switching cam 46 forming the cam mechanism 42 on the other hand. Member 47a
is rotating. Furthermore, the third motor 4
The driving force of No. 3 passes through the mounting plate 44 and rotates a light shielding member 48 fixed to the final gear 45a of the gear 45 of the gear mechanism. This light shielding member 48
detects the light of a transmission type sensor 50 provided on the back plate 1b of the chassis 1 through a printed board 49 so as to protrude inward of the chassis 1 every time a signal corresponding to the number of channels of input signals is input. is going on.

The clutch plate 47 is composed of two disc members 47a, 47a each having triangular protrusions 51 formed at a plurality of locations on its surface facing in opposite directions. Further, one disc member 47a fixed to the switching cam 46 is connected to the mounting plate 44 by a spring 53 inserted into a shaft 52.
It is urged in the direction of the other disc member 47a. Therefore, when the main shaft 9 is rotated in the direction of arrow A by the third motor 43, the projections 51, 5
Since the slopes 51a and 51a of 1 contact and the disk member 47a to which the switching cam 46 is fixed escapes toward the mounting plate 44, only the disk member 47a fixed to the relay gear 45b rotates. Further, the slope 51a,
51a contact and pass through, and when the main shaft 9 is reversed in the direction of arrow B, the vertical surface 51 of the protrusions 51, 51

At this time, the actuating cam 24 is arranged so that the actuating roller 26 of the bracket 14 does not fall into the notch 24a of the actuating cam 24 and make a dot on the recording paper 6. Furthermore, when the switching cam 46 rotates, the projection 46a of the switching cam 46 moves the plotter pen 30 up and down together with the swing arm 54 supported between the side plates 1a, 1a of the chassis 1. Note that in the initial state or in the state where dots are printed on the recording paper 6, the switching cam 4 is
A spring 57 that is locked between a locking pin 56 of a disk member 47a fixedly attached to a disk member 6 and a locking pin 44a of the mounting plate 44 causes the axis of the swing arm 54 to be aligned with the switching cam 46. It is held in the position shown in FIG. 4a with respect to FIG.

Next, the operation of the recording apparatus configured as described above will be explained.

First, when the dotting element 16 serving as dotting means is operated to record trends of various measured values on the recording paper 6 based on input signals, when the first input signal is input, the first motor 40 is driven and the recording is performed. The unit 8 moves along the main shaft 9 to a predetermined position on the recording paper 6 and stops (the state shown in FIG. 4a). Subsequently, the third motor 43 is driven, and the main shaft 9 rotates in the direction of arrow A to drop the dotting element 16 to make dots on the recording paper 6 (the state shown in FIG. 4b). Furthermore, when the next input 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 moves the main shaft 9.
further rotates, and the dotting element 16 and ink drum 18
By rotating the , the color of the dots can be changed. Then, when the recording unit 8 stops at the predetermined position, dots are recorded on the recording paper 6. Hereinafter, the above-described operation is performed every time an input signal is input, and trends corresponding to the number of input signal channels are recorded on the recording paper 6.

Next, when operating the plotter pen 30 serving as a printing means to record a character indicating the measured value on the recording paper 6, the first motor 40 is driven and the recording unit 8 is moved along the main shaft 9 onto the recording paper 6. It moves to a predetermined position and stops (the state shown in Fig. 4a).
Next, the third motor 43 reverses the main shaft 9 in the direction of arrow B to raise the plotter pen 30, and the second motor 41 rotates the extrusion cam 37 to move the plotter pen 30 onto the recording paper. 6 to the specified writing start position (5th
Figure a). Next, the main shaft 9 is rotated in the direction of arrow B by the third motor 43 to lower the plotter pen 30 onto the recording paper 6 (the state shown in FIG. 5b). Then, the plotter pen 30 is moved in the direction of the main axis 9 (X direction) and in the direction perpendicular to the drum 5 (Y direction) by the first motor 40 and the second motor 41.
direction) to record the characters on the recording paper 6. If the line recording is interrupted during this period, the third motor 43 rotates the main shaft 9 in the direction of arrow A to raise the plotter pen 30 again, and the first motor 40 After moving the recording unit 8 to the next predetermined position on the recording paper 6, the above-described operations are repeated to record desired characters indicating measured values on the recording paper 6.

[Effects of the Invention] As explained above, according to the recording apparatus of the present invention, the vertical movement of the dotting means and the printing means with respect to the recording paper is controlled by one motor via a gear mechanism, using rotational force during forward and reverse rotation of the motor. Since it is configured to selectively switch by simply transmitting the information to the dotting means or printing means, there is no need for switching parts for each dotting means and printing means. Recording processing can be performed arbitrarily and efficiently.

Furthermore, since trend recording and character recording can be performed with one recording device, the time required for recording can be reduced compared to the conventional method.
