Description of the Related Art Conventionally, as shown in FIGS. 4 and 5, a recorder 103 of this type has a carriage 103 slidably mounted on a sliding shaft 102 provided in parallel with a rotating shaft 101A of a recording drum 101. The pen 104 held on the carriage 103 is in contact with the recording paper conveyed onto the recording drum 101 so as to be able to come and go.

Then, the carriage 103 is moved along the sliding shaft 102 based on an external input signal, and the pen 104 is moved toward and away from the recording paper to realize required recording of characters and symbols. ing.

For this reason, in a conventional recorder, although not shown, as a mechanism for moving the pen 104 toward and away from the recording paper, the carriage 103 is rotated around the sliding shaft 102 to move the pen 104 up and down. When the power of the recorder is turned on, the pen 104 is kept separated from the recording paper by the action of a solenoid mechanism or the like, and when a signal related to recording is input, the solenoid mechanism or the like is operated in reverse. Thus, printing was performed by lowering the pen 104 on the recording paper.

[0005]

However, in such a mechanism using a solenoid mechanism or the like, when the pen is moved up and down with respect to the recording paper, the power must be turned on without fail. When the power is turned off, the pen 1
No. 04 comes into contact with the recording paper and is left as it is, leaving the ink oozing out on the paper.

As a mechanism for raising and lowering the pen with respect to the recording paper, a mechanism for manually raising and lowering the pen is known in addition to the above-described mechanism.

[0007] As shown in FIGS. 4 and 5, this mechanism includes a manual pen-up means 105. When the power is turned off, the pen-up means 105 is operated to raise the pen from above the recording paper. keeping.

That is, as shown in the figure, the pen-up means 105 has a carriage support rod 105A having a substantially semi-cylindrical section with only one outer peripheral surface cut off in parallel with the sliding shaft 102.

When B rotates, the cut surface of the carriage support rod 105A is disengaged from the carriage support surface, and the pen 104 is lifted away from the recording paper.

However, in the above-described pen-up mechanism, the pen is raised and lowered by manual operation. Therefore, for example, when the recording is stopped and the operation is interrupted, it is necessary to rotate the manual lever 110 every time. There is a problem that the operation is complicated and troublesome.

Accordingly, the present invention has been made in view of the above-mentioned problems, and its purpose is to provide a method that allows a worker to operate even if an accident such as a power failure or the like and the operation is interrupted and the power is turned off.

[0015]

1 is a diagram showing an embodiment of a pen-up device for a recorder according to the present invention. In the recorder according to this embodiment, a carriage 3 is slidably held on a sliding shaft 2 provided in parallel with a rotating shaft 1A of the recording drum 1, and recording paper (conveying over the recording drum 1 of the chart base 4) is used. (Not shown), a pen 6 held by the carriage 3 is provided so as to be capable of coming and going, and the carriage 3 is provided based on an input signal from the outside.
Is moved along the sliding shaft 2 to perform a contact / separation operation with respect to the recording paper, thereby realizing required recording of characters, symbols, and the like.

The recorder includes a lifting means 7 for raising the pen 6 and separating it from the recording paper when the power is off.

The lifting means 7 includes a carriage support member 8 arranged in parallel with the slide shaft 2 and a carriage support member 8.
, A pair of left and right pivot arms 9 attached to both ends, a swing member 10 that supports the carriage support member 8 via the pivot arm 9, and a swing member 10 that holds the swing member 10 in a direction to push up the carriage support member 8. Elastic means 11 and elastic means 1
1 and a drive motor 12 for urging the swing member 11 against the urging support force and releasing the push-up to the carriage support member 8. Sometimes, it has a function of exerting an elastic force so as to push the swinging member 10 up to the position shown in FIG.

In this embodiment, such a configuration has the following specific structure. That is, the swing member 10 has a pivot shaft 10A in the middle, and is swingably supported by the apparatus frame 13. One end of the swinging member 10 extends below an engaging element 9A provided below the rotating arm 9, and the other end extends toward the drive motor 12.

A gear 12B is provided on the output shaft 12A of the drive motor 12, and the rotational force of the drive motor 12 in the direction of arrow a in the figure is controlled by a two-stage gear 12C meshing with the gear 12B. This is transmitted to the gear 12D.

Further, the swinging member 1 is provided on the control gear 12D.
An engagement pin 14 for engaging the end of the pivot member 10 to swing the swing member 10 is attached, and a spring receiving pin 15 is provided.

The elastic holding means 11 is formed of, for example, a tension coil spring. One end is connected to a spring receiving pin 15 and the other end is connected to a support pin 16 provided on the apparatus frame 13, the contact plate 20 or the like. Connected. The strength of the spring by the elastic means 11 is set to be greater than the sum of the force for raising the pen 6 and the force for rotating the drive motor 12 when not energized, and smaller than the drive torque of the drive motor 12. ing.

In this embodiment, the upper limit stopper pin 17 for regulating the upper limit of the swing range of the swing member 10 is provided.
18 is provided on the device frame 13. Further, the control gear 12D is provided with a lower limit stopper pin 19, and on the apparatus frame 13 corresponding to the lower limit stopper pin 19, an impact plate 20 having a notch 20A is provided.
The lower limit stopper pin 19 abuts on the end face of the notch 20A to regulate the lower limit of the swing range of the swing member 10.

With this arrangement, when the drive motor is driven while the pen 6 is in contact with the recording paper, the control gear 12
D is rotationally controlled in the directions of arrows a and b from the position regulated by the lower limit stopper pin in a range in which the swinging member 10 does not push up the carriage support member 8, and the pen 6 moves in the front-back direction orthogonal to the recording paper.

The movement of the pen 6 in the direction parallel to the recording paper is controlled by another drive system (not shown), and printing of characters, symbols, and the like on the recording paper is performed.

In the above configuration, when the power of the recorder is turned on and the drive motor 12 is driven from the state shown in FIG. By rotating clockwise (direction of arrow a) in the figure via 12B and 12C, the engaging pin 14 is retracted from the swing member 10. Thereby, as shown in FIG. 1, the swinging member 10 is held at a position regulated by the lower limit stopper pin 19 without receiving a pushing-up force.

On the other hand, when the power is turned off in order to stop printing due to an unexpected accident (for example, a power failure) or the like or to stop printing, the urging force of the drive motor 12 is released, and the control gear 12D is resilient. The swinging member 10 is rotated in the counterclockwise direction in the drawing (the direction of the dotted arrow b) by the elastic force of the means 11 and pushes the swing member 10 with the engaging pin 14 of the control gear 12D. Thus, the swing member 10 pushes up the engagement element 9A of the swing arm 9 to swing the swing arm 9, lifts the carriage support member 8, and allows the swing member 10 to be supported by the upper limit stopper pin 17. The pen 6 is lifted from the recording paper to the height position of.

Therefore, in the above-described embodiment, even if an unexpected accident such as a power failure or the operation is stopped, printing on the recording paper is interrupted, and the power is turned off, the operation is automatically performed without the help of an operator. As a result, the pen can be lifted up and separated from the recording paper, and the ink can be reliably prevented from bleeding on the recording paper.

In the embodiment described above, when the chart base 4 is pulled out from the recorder main body while the power of the recorder is turned on, the pen 6 automatically moves up and separates from the recording paper. It has a configuration.

To explain this structure, a substantially inverted L-shaped elevating member 21 is mounted on the lower part of the rotating arm 9 with its upper flat surface in contact with the lower end surface of the rotating arm 9. The pivot arm 9 is pivoted by the elevation of the elevating member 21 about the fixed shaft 21A, and the pen 6 is moved up and down with respect to the recording paper.

The fixed shaft 21A of the elevating member 21 has
A torsion spring 22 is provided. One end of the torsion spring 22 is attached to the bent portion of the elevating member 21 and the other end is attached to the device frame 13, and biases the elevating member 21 in the direction of the arrow c in FIG. .

Further, a recording drum 1 is provided in the recorder main body.
The chart base 4 containing the recording paper to be conveyed above is accommodated therein. When the chart base 4 is accommodated in the recorder main body, the recording provided on the inner periphery of the recording drum 1 of the chart base 4 is performed. The paper holding section 4A is moved by the elevating member 21.
The pen 6 is in contact with the recording paper by pressing the elevating member 21 by contacting the lower end piece 21B which is the open end of the pen.

Then, when the chart base 4 is pulled out from the recorder main body, the pressing of the lower end piece 21B of the elevating member 21 is released, and the chart base 4 is rotated around the fixed shaft 21A in the direction of arrow c in the figure, and the flat surface is turned. The moving arm 9 is pushed up. As a result, the carriage support member 8 pushes up the carriage 3, raises the pen 6 from the recording paper, and holds the pen 6 away from the recording paper. Thereby, even when the chart base 4 is pulled out, the pen 6 is automatically raised and separated from the recording paper, so that it is possible to prevent the pen 6 from bleeding ink on the recording paper.
