Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pen-up device for a recorder, which has a pen mechanism for printing braille characters, symbols, etc. on recording paper.

[0002]

[Prior art]

 Conventionally, in this type of recorder, as shown in FIGS. 4 and 5, a carriage 103 is slidably held on a sliding shaft 102 provided in parallel with a rotating shaft 101A of a recording drum 101. The pen 104 held by the carriage 103 is in contact with the recording paper conveyed on the recording drum 101 so that the pen 104 can come into contact with and separate from the recording paper.

Then, the carriage 103 is moved along the sliding shaft 102 on the basis of an input signal from the outside, and the pen 104 is brought into and out of contact with the recording paper to record necessary characters such as characters and symbols. Has been realized.

Therefore, in a conventional recorder, although not shown in the drawing, as a mechanism for moving the pen 104 in and out of the recording paper, the carriage 103 is rotated around the sliding shaft 102 to move the pen 104 up and down. Therefore, when the power of the recorder is turned on, the pen mechanism 104 is kept away from the recording paper, for example, by the action of a solenoid mechanism, and when a signal related to recording is input, the solenoid mechanism is reversed. Printing was performed by moving the pen 104 down on the recording paper.

[0005]

[Problems to be solved by the device]

 However, in a mechanism using this type of solenoid mechanism, when the pen is moved up and down with respect to the recording paper, the power must be turned on. Therefore, for example, if the power is turned off during operation, the pen 104 will not print. There was a problem in that the ink came into contact with the paper and was left falling, leaving the ink bleeding out onto the paper surface.

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-mentioned mechanism.

As shown in FIGS. 4 and 5, this mechanism is provided with a manual pen-up means 105. When the power is turned off, the pen-up means 105 is operated to raise the pen above the recording paper. Holding.

That is, as shown in the drawing, the pen-up means 105 mounts a carriage support rod 105A having a substantially semi-cylindrical cross-section, in which only one outer peripheral surface is cut parallel to the sliding shaft 102, on a mounting frame (not shown). A pivot arm 105B is pivotally supported and a pivot arm 105B is attached to the carriage support rod 105A, and a guide pin 105C provided on the pivot arm 105B is configured to be lifted and lowered by an E-shaped lifting member 105D. Is connected to a lifting lever 108 via one guide pin 107A that slides along a guide slit 106 provided on the apparatus frame.

The lifting lever 108 is supported by the device frame so as to be able to swing around an intermediate support shaft 108A, and the other guide pin 107B is attached to one end of the lifting lever 108 and the other end is supported. A support shaft 110B of a manual lever 110 which can be rotated by a shaft 110A is attached. A toggle spring mechanism 109 elastically holds between the other guide pin 107B and the device frame.

Then, when the recorder is powered off, the manual lever 110 pivotally supported by the support shaft 110A is rotated to invert and lift the toggle spring mechanism 109 as shown in FIG. The lever 108 is swung to raise and lower the elevating member 105D. As a result, the rotating arm 105B rotates, the cut surface of the carriage supporting rod 105A is disengaged from the carriage supporting surface, and the pen 104 is lifted and separated from the recording paper.

However, in the above-described pen-up mechanism, the pen is raised and lowered by a manual operation. Therefore, for example, when the recording is stopped and the operation is interrupted, the manual lever 110 needs to be rotated each time. However, there is a problem that the operation is complicated and troublesome.

Therefore, the present invention has been made in view of the above-described problems, and an object thereof is to provide a worker with a manual operation even if an accident such as a power failure or an operation is interrupted and the power is turned off. It is an object of the present invention to provide a pen-up device for a recorder, which can automatically prevent the ink from bleeding into the recording paper by automatically separating the pen from the recording paper without borrowing a printer.

[0013]

[Means for Solving the Problems]

 In order to achieve the above object, a pen-up device for a recording meter according to the present invention has a carriage 3 slidably held on a sliding shaft 2 provided in parallel with a rotating shaft 1A of a recording drum 1, and the recording drum. A pen-up device of a recorder for contacting and separating a pen 6 held by the carriage 3 with respect to a recording sheet conveyed on a carriage 1, the carriage being arranged in parallel with the sliding shaft 2 and supporting the carriage 3. A gear 12D having a rotating arm 9 provided with a supporting member 8, a swinging member 10 for swingably supporting the rotating arm 9, and an engagement pin 14 engaging with one end of the swinging member 10.

Equipped with It is characterized by a door.

[0014]

[Action]

 When the power is turned off during the operation of printing characters, symbols, etc. on the recording paper, the urging supporting force of the elastic holding means 11 causes the gear 12D to rotate, and the engagement pin 14 of the gear 12D rotates the swinging member 10. Then, the carriage supporting member 8 of the rotating arm 9 is pushed up. As a result, the pen 6 is automatically lifted and separated from the recording paper, and the ink bleeding of the recording paper by the pen 6 can be prevented.

【Example】

 FIG. 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 slide shaft 2 provided in parallel with a rotary shaft 1A of a recording drum 1, and a recording paper (conveying paper on the recording drum 1 of a chart stand 4 ( (Not shown), a pen 6 held by a carriage 3 is provided so as to be able to come into contact with and separate from the carriage 3, and the carriage 3 is moved along the sliding shaft 2 based on an input signal from the outside, so that the recording paper The required recording of characters, symbols, etc. is achieved by performing contact and separation operations with respect to.

The recorder is provided with an elevating means 7 for raising the pen 6 to separate it from the recording paper when the power is off.

The elevating means 7 includes a carriage supporting member 8 arranged in parallel with the sliding shaft 2, a pair of left and right rotating arms 9 attached to both ends of the carriage supporting member 8, and a rotating arm. A swinging member 10 for supporting the carriage supporting member 8 via 9, a holding means 11 for holding the swinging member 10 in a direction to push up the carriage supporting member 8, and a biasing supporting force of the holding means 11. It is equipped with a drive motor 12 for urging the swinging member 11 against it and releasing the pushing up to the carriage support member 8. The elastic holding means 11 is provided with the swinging member 10 when the drive motor 12 is stopped. Has the function of exerting an elastic force to push up to the position shown in FIG.

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

Further, the output shaft 12A of the drive motor 12 is provided with a gear 12B, and the rotational force in the direction of the arrow a in the figure by the drive motor 12 is transmitted via the two-stage gear 12C meshing with the gear 12B. It is adapted to be transmitted to the control gear 12D.

Further, the control gear 12D is provided with an engagement pin 14 for engaging the end portion of the rocking member 10 to rock the rocking member 10, and a spring receiving pin 15 is provided. ing.

The elastic holding means 11 is composed of, for example, a tension coil spring, one end of which is connected to the spring receiving pin 15 and the other end of which is a support pin 16 provided on the device frame 13, the abutting plate 20, and the like. Connected to. Further, the strength of the spring by the elastic holding means 11 is set to be larger than the force that raises the pen 6 and the force that rotates the drive motor 12 when not excited, and smaller than the drive torque of the drive motor 12. Has been done.

In this embodiment, upper limit stopper pins 17 and 18 for limiting the upper limit of the swing range of the swing member 10 are provided on the device frame 13. Further, the control gear 12D is provided with a lower limit stopper pin 19, and an abutting plate 20 having a notch 20A is provided on the device frame 13 corresponding to the lower limit stopper pin 19 so that the lower limit stopper pin 19 is cut. By contacting the end face of the notch 20A, the lower limit of the swing range of the swing member 10 is regulated.

As a result, when the drive motor is driven while the pen 6 is in contact with the recording paper, the swinging member 10 moves from the position where the control gear 12D is restricted by the lower limit stopper pin to the carriage supporting member 8. The pen 6 moves in the front-rear direction orthogonal to the recording paper while being controlled to rotate in the directions of the arrows a and b within the range where the pen is not pushed up.

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

In the above configuration, when the power supply of the recorder is turned on, the drive motor 12 is driven from the state of FIG. 2 and the control gear 12D is moved against the elastic force of the elastic holding means 11. The engaging pin 14 is retracted from the swinging member 10 by rotating in the clockwise direction (the direction of arrow a) in the figure via the rows 12B and 12C. As a result, as shown in FIG. 1, the rocking member 10 is held at the position regulated by the lower limit stopper pin 19 without being subjected to the pushing force.

On the other hand, when the power is turned off in order to stop printing due to an unexpected accident (for example, power failure) or to stop the operation, the biasing force of the drive motor 12 is released and the control gear 12 D The elastic force of the elastic holding means 11 causes it to rotate in the counterclockwise direction (the direction of the dotted arrow b) in the figure, and pushes the rocking member 10 with the engagement pin 14 of the control gear 12D. As a result, the swing member 10 pushes up the engaging element 9A of the swing arm 9 to swing the swing arm 9, lifts the carriage support member 8, and the swing member 10 is supported by the upper limit stopper pin 17. The pen 6 is lifted from the recording paper to a predetermined height position.

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

By the way, in the above-described embodiment, when the chart frame 4 is pulled out from the main body of the recorder while the recorder is powered on, the pen 6 is automatically lifted to remove the recording paper from the recording paper. It is configured to leave.

To explain this structure further, in the lower part of the rotating arm 9, a substantially inverted L-shaped lifting member 21 is provided with the upper flat surface in contact with the lower end surface of the rotating arm 9. It is pivotally supported by the frame 13, and the raising / lowering member 21 about the fixed shaft 21A raises / lowers the turning arm 9 so that the pen 6 moves up / down with respect to the recording paper.

A torsion spring 22 is provided on the fixed shaft 21 A of the elevating member 21. The torsion spring 22 has one end attached to the bent portion of the elevating member 21 and the other end attached to the apparatus frame 13, and urges the elevating member 21 about the fixed shaft 21A in the direction of arrow c in the figure. ing.

Further, in the recorder main body, a chart base 4 containing the recording paper conveyed on the recording drum 1 is housed, and in the state where the chart base 4 is housed in the recorder main body, The recording paper pressing portion 4A provided inside the outer circumference of the recording drum 1 of the chart stand 4 contacts the lower end piece 21B which is the open end of the elevating member 21 to press the elevating member 21 and the pen 6 moves the recording paper. Is in contact with.

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 it rotates about the fixed shaft 21A in the direction of arrow c in the figure, and the flat surface is Push up the rotating arm 9. As a result, the carriage supporting member 8 pushes up the carriage 3 and raises the pen 6 from the recording paper to hold the pen 6 away from the recording paper. As a result, even when the chart frame 4 is pulled out, the pen 6 can be automatically lifted and separated from the recording paper, and the ink bleeding on the recording paper by the pen 6 can be prevented.
