Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing apparatus suitable for use in a recorder such as a pen recorder.

[0002]

As is well known, a pen recorder or XY.
A recorder such as a recorder records a signal supplied from the outside on a recording paper, and its recording method includes an ink type and a thermal type. When a waveform is recorded using such a recorder, it is often the case that the necessary conditions such as measurement conditions and recorded contents are written on the recording paper along with the recorded waveform. However, in a recording operation using this type of recorder, predetermined items are manually entered, which may cause a problem that the recorder is restrained for a long time for the entry in some cases.

Therefore, in recent years, a model has been put into practical use in which a recorder is equipped with a printing device to print a predetermined item. A printing device used in such a recording device employs, for example, a method in which a self-contained ink-type printing ring stamps the surface of the recording paper for printing, or a heat-sensitive method.

[0004]

By the way, in the printing apparatus used in the above-mentioned conventional recording device, in order to prevent the printed characters and the waveform recording from overlapping as much as possible, the corners of the recording paper are usually used. Printing is performed at a predetermined fixed position, and the printing size is set to a small value of about 2 mm. As a result,
Not only is it difficult to read the printed items, but it also becomes difficult to read when the printed characters overlap the recorded waveform. In addition, it is often the case that some recorders equipped with such a printing device cannot record signals during printing. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a printing device capable of printing characters of a predetermined size on an arbitrary position on a recording paper.

[0005]

SUMMARY OF THE INVENTION According to the present invention, a printing device mounted on a recording device for recording a signal on a recording paper surface fed at a predetermined speed to print on the recording paper surface has a plurality of printed characters on the outer circumference. A printing mechanism comprising a driving means for rotating the printing ring formed on the surface and a pressing means for bringing the printing ring into contact with the recording paper surface, and the printing mechanism is magnetically attracted and attached to an arbitrary position of the recording device. The mounting means for controlling and the driving means in accordance with a print signal supplied from the outside to set the rotational position of the print ring so that the character to be printed comes into contact with the recording paper surface, and And a control unit that operates the pressing unit according to the paper feed speed.

[0006]

According to the above construction, the mounting means mounts the printing mechanism at an arbitrary position of the recording device, and the control means sets the rotational position of the print ring so that the character to be printed comes into contact with the recording paper surface. At the same time, the print ring is brought into contact with the surface of the recording paper according to the paper feed speed of the recording paper.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side view showing the structure of a printer according to an embodiment of the present invention. The printing device shown in this figure is attached to a recording device such as a pen recorder via a magnet type attaching / detaching device 4.

In the figure, reference numeral 1 is a drive motor, and 2 is a pulley with a timing plate fixed to the rotary shaft of the drive motor. A marking indicating the origin position is provided on the outer peripheral direction of the pulley 2 with the timing plate. Reference numeral 3 denotes a sensor which is arranged so as to face the pulley 2 and generates an origin signal when the origin position is detected. Reference numeral 5 denotes a print ring that comes into contact with the surface of the recording paper for printing, and a character string made of stamp ink (gansin) type rubber is arranged on the outer peripheral edge of the print ring so as to divide the outer circumference into 16 equal parts. A sponge material that supplies ink to the rubber is embedded in the ring 5. The stamp ink type rubber in the print ring 5 can be easily changed to have various print sizes. Reference numeral 6 is a pulley fixed to the rotating shaft of the ring 5. Reference numeral 7 is a timing belt that transmits the rotation of the pulley 2 with the timing plate to the pulley 6.

Next, 8 is a connecting arm configured to connect the rotating shaft of the motor 2 and the rotating shaft of the print ring 5 while allowing them to rotate. In addition, this connecting arm 8
Is a structure that swings around the connecting portion on the motor 2 side. Reference numeral 9 is a solenoid bar whose one end is fixed to the connecting arm 8. The solenoid bar 9 pushes down the connecting arm 8 toward the recording sheet when a predetermined drive current is supplied. Reference numeral 10 is a spring that pulls the connecting arm 8 upward. With such a structure, when the solenoid bar 9 does not operate, the connecting arm 8 is pulled up to the position where the upper stopper 11 abuts. As a result,
A predetermined gap is formed between the print ring 5 and the recording paper surface.
This gap is about 1 mm to 1.5 mm. On the other hand, when the solenoid bar 9 is activated, the connecting arm 8 is pushed down to the position where the lower stopper 12 contacts. In this way, the print ring 1 can move up and down according to the operation of the solenoid bar 9.

When the printing apparatus having the above structure is turned on, first, the drive motor 1 rotates and the timing plate pulley 2 rotates. Here, the sensor 3 detects the origin position of the pulley 2 and supplies an origin signal to a control means (not shown). As a result, the control means controls the drive motor 1
To stop. In this state, the print ring 1
The first printed character of the six characters faces the surface of the recording paper.

Next, when print data designating a character to be printed is supplied from the outside to the control means, the control means rotates the print ring 5 so that the desired print character faces the recording paper surface. Next, when the print ring 5 reaches a desired position, the control means stops the drive motor 1 and causes the solenoid bar 9 to perform an engraving operation. As a result, the print ring 1 comes into contact with the recording paper to print one character. Then, by repeating the above process,
Predetermined items are printed on the surface of the recording paper. The engraving operation of the solenoid bar 9 described above is adjusted according to the feeding speed of the recording paper.

As described above, according to the above embodiment, since the printing device is fixed by the magnet type attaching / detaching device 4, the printing position on the recording paper surface can be changed in any way, and the characters of the selected size can be changed. Printing can be performed in synchronization with the paper feed speed of the recording paper.

[0013]

As described above, according to the present invention, the mounting means mounts the printing mechanism at an arbitrary position of the recorder,
The control means sets the rotational position of the print ring so that the characters to be printed come into contact with the surface of the recording paper, and brings the print ring into contact with the recording paper surface in accordance with the paper feed speed of the recording paper. It is possible to print at an arbitrary position on the paper, and it is possible to perform printing of a predetermined size by changing the print character size of the print ring. Further, the printing color can be changed by changing the ink color of the printing ring.
