Description

TECHNICAL FIELD OF THE INVENTION The present invention relates to an apparatus for controlling a pen plate that is applied to the tip of an ink writing recorder.

Background Art and Problems In an ink writing recorder, the nib of the pen attached to the bon motor is exposed to air and the ink dries out when the recorder is left unused for a long period of time. It becomes clogged with ink, making it impossible to supply ink to the nib the next time the recorder is used. For this reason, in the past, a separately prepared pen plate with a rubber-like cutter attached was placed over the pen tip and sealed with a rubber-like material, so that the ink that had been supplied to the end of the pen tip was released into the air. I stored the recording device without touching it, and the next time I used it, I removed the pen plate from the pen tip and resumed recording.
Operators often forget to remove the pen plate from the nib and damage the pen nib, and due to the complexity of the work, operators do not use the 4-pen plate (the nib is clogged with ink). I had lost the main unit.

Also, a device has been considered that moves the pen tray back and forth using only the Lenaut operation to supply the pen, but this has the drawback that automatic switching and remote control are not possible.

Purpose of the Invention In view of the above-mentioned points, the present invention provides an extremely easy-to-operate ink character recorder in which the pen tray is automatically moved to the supply position or the standby position in conjunction with the 4-in vertical mechanism. It is an object of the present invention to provide a pen tray control device in the present invention.

Summary of the Invention The present invention includes a cam connected to a rotating shaft, a pen lifting arm that moves the υben up and down by the rotation of the cam, and a drive arm that moves the position of the pen tray. It is characterized by the fact that it can be used to control and hang the pen plate.

Embodiment 1 to 5 show a first embodiment of the present invention, and FIG. 1 is an exploded perspective view thereof. In the figure, (1) is a device that performs rotational motion, such as a stepping motor, and (2)
is the motor shaft, (3) is the cam, (4) is the pin, (5)

Figure 2 shows the recording state of the device in Figure 1. Figure 2 shows a partial plan view, Figure 2B shows a side view, and Figure 2C shows the recording state of the device shown in Figure 1.
is a sectional view taken along the AOA line in FIG. 2B. In the figure, parts corresponding to those in FIG. 1 are given the same reference numerals.

As shown in the figure, in the recording state, the cam (3) lowers the lifting arm (9), and the drive arm (5) pulls the pen tray holder (7) to the standby position on the cam (3) side. As shown in Figure 2 C, the cam shaft (2) is fixed to the motor shaft (2), and the cam (3) is attached to the cam shaft C (g). The roller α is in contact with the cam (3) and moves up and down using the cam (3) as a fulcrum.
The position of the cam (3) is also close to the center of the shape. Therefore, the in-up rod 0→ is located below and away from the wave θ]. Therefore, the pen tip (13a) of the pen 01 is in contact with the recording paper a◆ and ready for recording.

FIG. 3 shows the device shown in FIG. 1 in a pen-raised state; FIG. 3 is a partial plan view, and FIG. 3B is a side view. When the motor (1) is driven from the recording state shown in Figure 2 and the cam (3) fixed to the motor shaft (2) is rotated counterclockwise, the cam (3) moves from a position close to the center of the shape. Move to a position with a slightly larger radius than the center, and raise the in-raise arm (
9), press the 9th roller (11) and move the pen lifting arm (9) upward using the axis α1 as a fulcrum.4. The pen lift frame (1) hits the pen (1'3) and pushes it down.

Therefore, the pen tip (13a) separates from the recording paper (1→.At this time, even though the cam (3) has rotated counterclockwise, the amount of movement of the drive arm (9) is 7), the in-dish receiver (7) does not move because it is within the range of the slit hole formed in the drive arm (5) guided by the guide pin OQ installed in the middle of the drive arm (5).

FIG. 4 shows a state in which the apparatus shown in FIG. 1 is in the middle of supplying four trays; FIG. 4 is a partial plan view, and FIG. 4B is a side view thereof. When the motor (1) is driven to further rotate the cam (3) in the counterclockwise direction from the raised state shown in FIG. 3, the cam (3) moves to a position where the center diameter is even larger than in the raised state. Push up the roller α further and raise the in-lift arm (9)
moves around the axis aO as a fulcrum, and the pen lifting rod α) pushes up the pen further. At the same time, the drive arm (5) also moves due to the rotation of the cam (3), and unless the amount of movement exceeds the range of play of the slit hole of the drive arm (5), the drive arm (5) is moved by the crab tray receiver (7). Press the guide bin OQ. Therefore, the inner tray holder (7) rotates around the axis 0→, and the pen tray (6) attached to the inner tray holder (7) moves towards the pen tip (13a).
) to the bottom.

FIG. 5 shows the pen tip of the device shown in FIG. 1 in a sealed state, and FIG. 5 shows a partial plan view, and FIG. 5 BV shows a side view. When the cam (3) fixed to the motor (1) is further rotated counterclockwise from the state shown in Fig. 4 and stopped at the position shown in Fig. 5 B, the 4-in lifting arm (9) will move from the position of the cam (3). shape is second
Since the radius is intermediate between the radius shown in the figure and the radius shown in FIG. 3, it moves about the axis 00 as a fulcrum, and the pen lifting rod α) lowers from the state shown in FIG. 4.

Accordingly, Ben 03's pen tip (13a) is Ben M (
6) is placed on top. On the other hand, the drive arm (5) moves due to the rotation of the cam (3), but the amount of change is very small and does not deviate from the width of the pen plate (6). Pen plate (6)
To do this, a rubber plate α is adhered to the contact surface of the pen nib (13a), and a sealed state is created between the rubber plate Qf) and the nib (13a) to prevent the ink from drying. The recorder is stored in the ink sealed state shown in FIG. 5, and the pen tip is released from the sealed state when it is used again. In other words, in this example, stepping
Rotate the motor (1) clockwise to return the state shown in FIG. 5 to the state shown in FIG. 2. If the drive motor has some kind of failure during this process and stops operating, the cam (3)
When one end is pushed in the axial direction and rotated clockwise, the pin 07 (nine places above the camshaft) comes out of the groove of the cam (3), and the cam (3) is separated from the motor shaft (2) (the second pin 07). (See Figure C). Therefore, motor drive can be switched to manual operation.

In these figures, the same reference numerals are given to the parts corresponding to those described above, and the explanation thereof will be omitted.

In this example, the rotation range of the cam is manually controlled by a lever instead of being driven by a motor. The α mark is the lever, the handle is the large gear, the CO is the small gear, (22+ is the bearing, and (to) is the gear shaft. It moves the large gear handle attached to (to) and meshes with it. When the pinion (20) is moved, one end moves the cam (3) fixed to the other end of the shaft (2), which is fixed to the pinion (20), and the same effect as in the first embodiment can be performed. .

Next, a method of electrically driving the pen up/down mechanism and the pen tray feeding mechanism in the first embodiment will be explained.

FIG. 10 is a block diagram showing an example of the driving method. SWl is the record switch, Sw2 is the stop switch.
Switch % SW3 is a Benrest switch, and SW4 is a power switch. The record switch SW, as shown in FIG. As shown in Figure 3, this is a switch that raises the pen tip and stops conveying the recording paper while retracting the pen tray, that is, puts the device in the pen-up state.The pen rest switch Sw3 is as shown in Figure 5. This is a switch that moves the pen tray below the pen nib and places the pen nib on the 4-inch tray to stop conveyance of the recording paper, that is, to place the device in the pen nib sealed state.Latch circuit L/jT1
temporarily stores a new switch state each time the switches SW1 to SWS are switched. Each switch SW1~SW
3 are logically or mechanically interlocked and are stored in the latch circuit with only one switch being turned on. Every time a new signal is given to latch circuit LAT 1, the previous old signal is
It is transferred from I to the latch circuit LAT2 and stored.

The comparator COM compares the newest signal stored in the latch circuit LATI with the previous signal, and outputs a signal to drive the monostable multivibrator W only if they do not match. At the same time, positive and negative signals are applied to the motor drive unit MDR to determine the rotation direction of the motor (1).

For convenience of explanation, the rotational direction of the motor from the closed state to the recording state is defined as the forward direction, and the opposite direction is defined as the reverse direction. When a signal from the record switch SW1 is input, the flip 70-tube FFI is set and outputs a signal that turns on the paper feed drive unit. Also, the signal of flip-flop 7″FFI B % stop switch SW2 or Happenrest switch SW3 is OR.
-) When input through ORI, it is reset and outputs a signal that turns off the paper feed drive unit. In this embodiment, there is a motor for transporting paper in addition to the motor (1) that drives the cam (3), and when a signal to turn on the paper transport υ drive unit is output, the recording paper is transported. It is like that.

Monostable multivibrator waist output counter CTR
Give a load signal to the counter CTR and selector SSL
The count number that was set is stored. At the same time as the monostable multivibrator ΔW is removed, a signal is also given to the flip 70 tsuzo F'F2 to set it. Work as given. When the signal selector SSL changes between the recording state and the pen-up state, or between the in-in-up state and the pen-tip sealing state, the signal selector SSL resets ``0'' on the OR gate OR2 and sets the number of 70 counts. , the change between the recording state and the pen tip sealing state [,j is given "1" from the or-ro "-1-oIc2" and a count number of 140 is selected. Counter CTR) subtracts and counts the returned count number from P% machine SSL, and when the count reaches 0, outputs a ++r low signal and flips the counter. Reset F2 and r-) ANI
) 1 to prevent the passage of the clock signal.

As a result, the clock signal Q supplied to the motor drive section MDH disappears and the rotation of the motor (1) stops.

Motor Ij → < L, 'J part MDR determines the rotation direction by the forward rotation or reverse rotation of the comparator COM and rotates the motor by the number of clock pulses of ANDI. This is a circuit that advances step (1).

- As an example, a case will be explained in which the penrest switch 1llW3 is pressed while the record switch SWi has already been pressed. Signal A given when each switch tile 1 to SWs is pressed.

B and C are υ in Table 1.

Table 1 When switch sw1 is pressed, latch circuit LAT
The output of I, that is, the input of comparator COM A r B , C
are respectively 1.0.0. In this state, switch 5
When is pressed, A, B, and C change to o, o, and i, respectively, but at the same time, the output of the latch circuit LAT2, that is, the input of the comparator COM, A'l B/, and C' change to the previous data 1, Gives 0.0. Comparators COM are A, B, C and A
The inputs of ', B', and C' are compared and a signal is output to the monostable multivibrator MMV only if they do not match, so in this example, the signal is given to the monostable multivibrator MMV. Sunda, and dirt AND2 Hanito C
are both 1, and r −) AND3 produces an output when A and C' are both 1, but in this example, A,
B.

Since C is 0.0.1 and A/, B/, and C/ are 1.0.0, A' and C are both 1, or r -) O
R2 produces an output and signal selector SSL selects 140. The signal selected by this signal selector SSL is the load signal of the monostable multivibrator
Stored in R. At the same time, a signal is also applied to flip-flop FF2, which opens ANDI to allow a clock signal to pass through, which is applied to counter CTR and motor drive unit MDR. On the other hand, the flip roller 'fFF1 is reversed by receiving a signal via the ORI (◆r -) ORI, turning off the paper transport υ drive unit and stopping the transport of the paper.

The counter CTR, which stores a count number of 140, subtracts and counts, and when the count reaches 0, it outputs a zero-signal and gives it to flip FF2, and closes the ANDI to prevent the passage of the clock signal. hinder. The motor drive unit MDR1'$ motor (1) is driven by the 140 clock pulses given up to this point. Here, the weighting of A, B, C and A/, B/, C/ is set to 4 and 2.1, respectively, and A+B+C<A'
+B'+C', comparator COM is motor drive unit MDR
to issue a reverse signal. In this example, A, B, C
are Q, Q, 1 and A/, B/, C/ are 1,0.0, so A0B+C-1, A'+ B'+ C"x 4
Since A+B+C ('A'+B'+Cθ) is established, the comparator COM outputs a reverse rotation signal, and the cam (3) changes from the state shown in Fig. 2B to Fig. 3B and Fig. 4B. Figure 5B
Rotate to the state of .

The above is a case where the penrest switch sw5 is pressed while the record switch sw1 is pressed, but since the operations in other cases are the same as described above, the explanation will be omitted. Moreover, as shown in FIG. 10, OR・r−)OR3
The logical sum of the state of the power switch SW4 and the state of the fourth-rest switch sw'3 is
If you apply it to the latch circuit LATI as a signal of W5 and hold the power supply voltage for a certain period of time with a capacitor etc. so that the power supply voltage does not drop until the pen tip changes to the sealed state after turning off the power switch 8W4, recording will be possible. Even if the power switch SW4 is turned off in this state, the mechanism section continues to be driven until the pen tip is sealed. Therefore, even if you forget to press the pen rest switch SW3 after using the recorder and turn off the power switch SW4, the pen tray will be supplied and the pen tip will be sealed, so there will be no inconvenience the next time the user uses it. You get the advantage of not having to spend money.
