Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a marker device that records desired information on recording paper by moving a pen on the recording paper in a direction substantially perpendicular to the running direction while running the recording paper. In particular, the present invention relates to a marker device that can record multiple pieces of information such as time marker information, operation start information, control start information, abnormality occurrence information, etc. in an identifiable format even when only one pen is used.

As is well known, in a recorder that feeds a recording paper over time and records detected temperature information on the recording paper, it is possible to record accordingly by reducing the number of pens that perform recording operations. Since the types of information are also reduced, devices that need to record a wide variety of information will require a correspondingly large number of pens, making it difficult to miniaturize the device.

It is characterized by making it perform.

The present invention will be described below with reference to embodiments shown in the drawings.

FIG. 1 is a perspective view showing a first embodiment of a marker device according to the present invention. In this figure, 1 is a dot recorder that records temperature information, etc. A dot recording mechanism 2 is provided on the left side of the dot recorder 1 (left side in the figure); When the recording paper 4 of the recording section 3 is running in the direction of arrow A as the drum 5 rotates, the dot recording device 2 records marks corresponding to temperature information etc. on the left side of the recording paper 4. It is done.

On the other hand, a marker device 6 is provided on the right side of the dot recorder 1, and the marker device 6 records various time information such as time marker information and operation start information on the recording paper 4. The drive section 7, lever section 8, and marker section 9 that constitute this marker device 6 will be explained in detail below.

First, the drive unit 7 connects the first motor 10 and the first
Shielding plate 1 provided at the upper end of the shaft 11 of the motor 10
2, a first rotational position detector 15 consisting of a magnet storage plate 13 and a reed switch storage plate 14 provided above the magnet storage plate 13.
and a cam 16 fixed slightly below the upper end of the shaft 11. When a first marker signal is output from a controller (not shown), the first motor 10 is energized and starts rotating in the direction of arrow C from the state shown in the figure, after which the shielding plate 12 is again connected to the magnetic plate 13.
When the magnetic field lines generated by the magnet plate 13 are blocked between the reed switch plate 14 and the reed switch plate 14, the reed switch 1 in the reed switch plate 14
8 is in an open state, and this first motor 10 is deenergized. Further, on the rear side of this first drive mechanism 17, there is another drive mechanism 19 that constitutes the drive section 7.
(Second drive mechanism 19) is provided. Second
Similar to the first drive mechanism 17, the drive mechanism 19 includes a second motor 20 with a reduction gear, and a shielding plate 2 when fixed to the upper end of the shaft 21 of the second motor 20.
2, second and third rotational position detectors 23 and 24 for detecting the rotational position of this shielding plate 22, and a cam 25 fixed to the shaft 21, and the controller When the marker signal is output, the second motor 20 is energized, and when the shielding plate 22 reaches the position of the third rotational position detector 24 by 1/4 rotation in the direction of arrow C from the position shown in the figure, the second motor 20 is activated. 1 motor 20 is temporarily deenergized. Thereafter, when the controller stops outputting the second marker signal, the second motor 20 is energized again and further rotates in the direction of arrow C, and the shielding plate 22 detects the position of the second rotational position detector 23. When it reaches this point, that is, when it returns to its original position, the second motor 20 is deenergized again.

In addition, the lever portion 8 is a lever 2 that is long in the front and back direction.
6, and a support shaft 27 that is arranged slightly rearward from the front end of the lever 26 and supports the lever 26 so as to be rotatable in the horizontal direction.
The drive section 7 is located behind the support shaft 27.
The same lever 26 is located at the location corresponding to the cams 16, 25.
Arms 28 and 29 are formed that extend in the width direction, and rollers 30 and 31 that abut the cams 16 and 25, respectively, are provided at the tips of these arms 28 and 29.
is provided. On the other hand, a protrusion 32 is formed on the right side of the front end (tip) of this lever 26, and a connecting rod 32a of a marker pen 33 is in contact with this protrusion 32.

Here, the marker section 9 in which the marker pen 33 is provided will be explained. That is, the marker portion 9 is connected to the slide bar 3 arranged horizontally.
4, 35, a marker pen 33 that moves along these slide bars 34, 35, and a pen 36 that is attached to the lower front of this marker pen 33. This marker pen 33 moves along one slide bar 35. The marker pen 33 is always biased in the direction of the arrow D by a coil spring 37 inserted into the marker pen 33, and the front end of the marker pen 33 is biased downward by its own weight so that the pen 36 is always in contact with the recording paper 4. ing.

Next, the operation of this embodiment constructed as described above will be explained with reference to the plan views shown in FIGS. 2A to 2B.

Now, when the controller is not outputting both the first and second marker signals, as shown in FIG.
5a are not in contact with the corresponding rollers 30 and 31, the central axis 37 of the lever 26 coincides with the traveling direction A of the recording paper 4, and the recording paper 4 follows a straight line _S1 without ups and downs as it travels. be painted. Next, if the controller outputs and holds the second marker signal, the second motor 20 rotates 1/4 in response to this, as shown in FIG. Projection 2 of cam 25 fixed to shaft 21
5a presses the roller 31, and the central shaft 37 of the lever 26 is tilted about the support shaft 27 with respect to the running direction A of the recording paper 4, and the marker pen 33 connected to this lever 26 is tilted in the horizontal direction. is moved by a distance x ₁ . Here, the length of the protrusion of the cam 25 is a, the distance from the support shaft 27 to the arm 29 is l ₂ , and the length of the support shaft 27 is
If the distance from the to _the connecting rod 32a is L, the moving distance _{x 1} of the marker pen 33 is expressed as A straight line S ₂ is drawn that is shifted laterally by a distance x ₂ . Next, in this state, if the controller outputs a first marker signal, the first motor 10 starts rotating in response to this, and is fixed to the shaft 11 of the first motor 10 as shown in FIG. The roller 30 is pressed by the cam 16, and the lever 26 is further rotated. That is, the length of the protrusion of the cam 16 is a, and the length of the protrusion from the support shaft 27 is
If the distance to the arm 28 is l ₁ , then the lever 26
The marker pen 33 connected to the marker pen 33 is moved laterally from the position shown in A to the position shown in C in the same figure by a distance x ₁ shown by x ₁ ≒ L/l ₁・a (2) It turns out. In this case, since the first motor 10 rotates continuously until it completes one revolution, a mark _S3 is drawn on the recording paper 4 that projects from the straight line _S2 by ( _x1 - _x2 ), and then the controller The marker pen 33 continues to draw a straight line S 2 a continuous to the straight line S ₂ until the marker pen 33 stops outputting _the second marker signal. below,
The above-described operations are repeated in response to the output of the controller, and the required information is recorded on the recording paper 4.

In this marker device, since the lengths from the spindle 27 to the arms 28 and 29 are set to be different, the arms 28 and 29 can be connected to the cams 16 and 25 of the same shape. Even if the arms 28 and 29 are energized, the length x of the markings recorded on the recording paper 4 can be changed, and the energization time of each arm 28, 29 is made different.
Since the width W of the markings recorded on the paper 4 is varied, even if a plurality of markings are superimposed on the recording paper 4, they can be easily read.

Also, in this case, the lever 26 is biased using the first and second motors 10 and 20;
In this case, the number of motors may be reduced by using one motor and selectively supplying the driving force of this motor to each cam 16, 25 using a driving force intermittent mechanism such as an electromagnetic clutch mechanism. By using a rotary solenoid instead of the second motor 10, 20 and controlling the rotary solenoid to open, positioning of each cam is unnecessary.
The rotational position detectors 15, 23, and 24 for detecting the rotational position of each cam may be omitted.

Furthermore, in the embodiment described above, the lever 26
Although the case where two arms are provided has been described, it is also possible to use three or more arms to further increase the number of information that can be recorded. In this case as well, since it is sufficient to provide the same biasing mechanism for each motor that biases each arm as many times as there are arms, it is possible to standardize parts and design each biasing mechanism individually. The cost can be kept lower than in the case of other cases, and the assembly can be made easier and the structure can be simplified.

Next, a second embodiment of the marker device according to the present invention will be described.

FIG. 3A is a plan view showing a second embodiment of the present invention. The marker device shown in this figure is the lever 26.
Arms 28, 29, 40 are provided on both sides of a, and each cam 1 contacts rollers 30, 31, 42 at the tips of these arms 28, 29, 40.
6, 25, 43 are arranged in front of each roller 30, 31, 42, and when each of these cams 16, 25, 43 is not biased, a leaf spring 44 provided at the rear end of lever 26a is applied. Twist lever 26a
is at the neutral position, and each cam 1
Any one of the cams 6, 25, and 43, for example, the cam 16, is biased so that its protrusion 16a moves toward the roller 30.
Even when the lever 26a comes into contact with the lever 26a, the other cams 25 and 43 do not interfere with the rotation of the lever 26a, as shown in FIG.

In this embodiment, the lever 26
Since the arms 28, 29, 40 are provided on both sides of the lever 26a, the distance from the support shaft 27 to each arm 28, 29, 40 can be made close, and even if the total length of the lever 26a is fixed, the information The number can be increased.

Further, by rotating the cams 16 and 25 in the direction of arrow E, the marker pen 33 can be made to swing in the direction of arrow F, and by rotating the cam 43 in the direction of arrow G, the marker pen 33 can be made to swing in the direction of arrow H. Since it is possible to distribute the information to multiple sources, it is possible to further advance the multiplex recording of information. That is, in this case, as shown in _FIG .
marking S ₃ b corresponding to the third marker signal;
When sequentially recording marks S ₄ , the cam 25 is energized and held to start recording the mark S ₂ b, then the cam 16 is energized to record the mark S ₃ b, and then the cam 25 is If the pressing operation of the roller 31 is once released, the cam 43 is energized to record mark S ₄ , and then the cam 25 is energized again to record mark S ₂ b successively. ,
These first to third marker signals can be multiplexed and recorded. In this case, each cam 16, 2
By making it possible to reverse the direction of rotation of 5 and 43, it is possible to further increase the amount of information that can be recorded.

Each arm is formed on the side of the levers 26, 26a, and rollers 30, 31, 42 are provided at the tips of the arms. This lever 2
The rollers 30, 31, 42 may be driven by the cams of the respective motors arranged below the rollers 6, 26a.

As explained above, the marker device according to the present invention has a plurality of pressing points in the longitudinal direction of the lever, and selectively presses each of these pressing points using a drive mechanism provided near the lever. Since this is rotated by the angle corresponding to the pressing point, the moving distance of the marker pen driven by this lever can be made different depending on each information, and the marker pen can be Even if the device is miniaturized, it is possible to multiplex record a plurality of pieces of information in a readable manner, and it is possible to secure a sufficient number of information that can be recorded even if the device is miniaturized.
