Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a device for switching telephones in conjunction with displaying the next line.

For displaying the destination of employees in traditional workplaces such as technology companies and factories,
For Kutoe, each person writes their destination with chalk on a blackboard, or places a destination display board 200 like the one shown in Figure 1415 on each person's desk and rotates the needle 201 to match the destination. I'm leaving my seat.

The phone remained on the desk.

Problems to be Solved by the Invention With the above-mentioned method of writing on a blackboard, the whereabouts of the person cannot be determined unless one goes to the blackboard. If you use the destination display board 200 shown in Figure 15, you won't know where the person went unless you go to the person's desk 1.

Depending on the person's position and position in the workplace, some people may have their desks located in multiple locations within the company.

These people often change places during their time.

Therefore, it is difficult to know where to go. If a call comes in while the person is away, the call cannot be answered. Even if someone near the desk answers the phone for them, they may not be able to reach an understanding.

Find out where you are going and ask the operator to connect you to another phone.1
It takes a lot of time and effort to tell the destination number and have the other party fix it.

In order to solve this problem, there is a method of calling using public address equipment, but it is only a noise for people other than those involved, and depending on the location, only the call can be heard.

It is prohibited by law to modify or add telephones connected to the telephone lines of the Nippon Telegraph and Telephone Public Corporation (hereinafter referred to as the "public telephone communication line") without permission, or to branch out the telephone communication line of the public corporation. It is stipulated that all equipment connected to public telephone communication lines must be certified by Nippon Telegraph and Telephone Public Corporation.

Therefore, for example, by using a converter 202 as shown in figure s16, two to three telephones can be connected to one public telephone communication line, and the switching lever 202 of the converter 202
Is it possible to selectively connect and use one of the telephones to the public corporation's telephone communication line by switching the terminals using an assisted operation?

Since the installation location of the converter 202 is limited to one location, it is not possible to switch the telephone in a place where there is no converter, so I went to the installation location of the converter 202 and switched the converter using an assisted operation. Then go back and use the phone. There was the inconvenience of having to contact the person near the switch in some way to have it switched off.

Recently, it has a transfer function. The so-called button telephones are used for the same purpose as mentioned above, but are connected to the same line.

When I receive a call, all the bells ring at the same time, and I don't know who the call is for until I answer it, and if I don't answer it, it's probably the incoming line or it's not my line. If the owner of the phone is out of town, the phone will not respond to any button calls and may cause trouble to the caller. It was a cabinet. The transfer requires the effort of a third party.

- Even if the exchange has an absentee self-help transfer function.

There is also C, which requires a troublesome dial operation and makes you forget to cancel the transfer. Furthermore, there are no pushbutton telephones or switchboards on the market that can also display the destination. Furthermore, the installation of key telephones and switchboards with private transfer functions requires considerable expense.

The purpose of the present invention is to solve the above-mentioned technical problems.

To provide a device for displaying a destination and switching between telephones, which can be realized by simple means without violating the law.

Means to solve problems The present invention includes a plurality of telephones.

txt is distributed near the location of each telephone.

An input means that can perform input corresponding to each location.

Display means disposed individually at the location for displaying the location input by the input means.

A device for switching one destination and a telephone, characterized by comprising a telephone communication line as an input means and a switching means capable of selectively connecting one telephone to the telephone corresponding to the input location. be.

According to the present invention, it is possible to cause the input means placed near the place where the telephone is placed to display one line ahead on the display means individually placed at said place, and Simultaneously with the operation of the means, the telephone can be selectively switched to the telephone at said display location in succession.

L-shaped arms 27R and 27L (telephone switching means) are rotatably attached to the base (not shown) of the IA by pins 29R and 29L fixed to the base (not shown) J.

The bin 3 is placed in the center of the long side of the L-shaped arms 27R and 25L.
0R and 30L are fixed respectively, and these bottles 30R and 3
Long holes 32R and 32L provided at one end of the horizontal guide members 31R and 31L are loosely inserted into the 0L, respectively, and the plunger 33
R and 33L are tied together and plunger 33R
, 33L of the electromagnetic plungers 34R, 34L installed on the left and right sides of the housing 24b of the converter 24.
Sometimes it is biased in the horizontal direction in Figure 5. Here, the Kameda plungers 34R and 34L both attract the plungers 33R and 33L inward during excitation. This is a so-called pull-type electromagnetic plunger.

The short side ends of the L-shaped arms 27R, 27L are connected to the vertical guide members 37R, 37 by the bins 35R, 35LICj.
Each one end of L is connected to a bottle. Plungers 37R, 3 at the other ends of the vertical guide members 37R, 37L

Plungers 37R, 37Lσ, the electromagnetic plunger 34
When the electromagnetic plungers 36R and 36L, which are installed perpendicularly to the axial direction of the plungers R and 34L, are energized, the kettle 5
It is biased in the direction of arrows C and D in the figure (downward in FIG. 5). Here, both the electromagnetic plungers 36R and 36L are attracted inward during excitation. This is a so-called pull-type electromagnetic plunger.

With reference to FIGS. 5 and s6, telephone switching means 10A
+7) The previous work will be explained below.

(1) When switching the switching lever 24a from the third position to the first position. In this case, the electromagnetic plungers 34R, 36
R is excited. When the electromagnetic plunger 34R is excited, the plunger 33R and therefore the horizontal guide member 31111
j It is attracted in the direction of the arrow R, but due to the play of the long hole 32R provided in the horizontal guide member 31R, the electromagnetic plunger 34R is attached to the bottle 30R fixed to the L-shaped arm 27R.
Even if it is excited, the pressure is not directly applied to the wall 1, but it is concentrated near the inner end 39R of 30R and 32R. - 10,000, electromagnetic plunger 36
When R is excited, the L-shaped arm 27R uses the attraction force in the direction of arrow C (downward in Figure 5) to attach the fixing pin 29.
The horizontal member 26 rotates clockwise around R.
．． Therefore, the elongated hole 25 is displaced in the direction of the arrow R, and the switching knee 24aσ is pressed in the direction of the arrow R, and the IJ
The electromagnetic plunger 34 is angularly displaced from the 13th position to the 1st position.
Even after R and 35H are demagnetized, there are two retaining mechanisms for the switching lever 24b.

The state of the first position shown in FIG. 6(b) is maintained. At this time, the outer end 4O of the long hole 32L provided in the bottle 30Lff of the L-shaped arm 27L and the plunger 31L is used to adjust the angular displacement of the L-shaped arm 27L in the clockwise direction.
Contact L and pull out Kari 33L. On the other hand, the L-shaped arm 27R is on the bin 30R.

It is in contact with the inner end 39R of the long hole 32H provided in the horizontal guide member 31R. The switching lever 24a is then machined.
The switching from the third position to the first position lid is completed.

(When switching the 21 switching lever 24a from the 1143 position to the second position,
36L is excited. In contrast to the previous work described in item (1) above, the L-shaped arm 27L fixed pin 29
angular displacement in a counterclockwise direction about L, thereby causing horizontal member 26. Therefore, the elongated hole 251d is displaced in the direction of the arrow mark (left side in FIG. 5) I, and the switching lever 24b
It is pressed in the direction of the σ arrow and angularly displaced from the third position to the second position.

Even after the electromagnetic plungers 34L and 36L are demagnetized, they are maintained in the second position shown in FIG. 6(C) by the holding mechanism of the switching lever 24b. At this time, the bottle 30Li of the L-shaped arm 27R mentioned above comes into contact with the outer end 40R of the long hole 32R provided with the plunger 31RIC, and the lever 33R is pulled out. On the other hand, a bottle 30Ltj with an L-shaped arm 27L
, is in contact with the inner end 39L of the long hole 32L provided in the horizontal guide member 31L. Above 2 means switching lever 2
The switching from the third position of 4a to the second position is completed.

(3) When switching the switching lever 24a from the $1 position to the third position. In this case, electromagnetic plungers 34R and 34L
are both excited at the same time. Electromagnetic plunger 34R, 3
4L is excited, horizontal guide members 31R, 31Ln
Tomoko receives the pulling force of the electromagnetic plungers 34R and 34L, respectively, and is displaced in the direction of the arrow mark (to the left in FIG. 5) of the horizontal guide member 31R, and at this time, the horizontal guide member 31R is The outer end 40L of the long hole 32L is the L-shaped arm 2.
Pull the fixing pin 30L of 7R in the direction of the arrow mark, so L
The horizontal member 27L is angularly displaced in the counterclockwise direction centering on the fixed pin 29L, and the horizontal member 26° is therefore
is also displaced in the direction of the arrow mark, and presses the switching lever 24a in the direction of the arrow mark against the force of the self-holding mechanism of the switching lever 24a.

In this way, the switching lever 24a is angularly displaced from the first position to the third position. At this time, the electrographic plunger 34R is also energized at the same time, pulling the horizontal guide member in the direction of arrow R (to the right in FIG. 5).

The switching lever 24a changes from the 1st position in Figure 6(b) to the 3rd position in Figure 6(a) even after the magnetic plungers 34R and 34L are turned off. The holding mechanism holds the lever 24a in the third position. By the above, the switching lever 24a is moved from the first position to the third position.
The changeover to the position is completed.

(4) When switching the switching lever 24a from the second position to the third position, in this case as well, @H1
15:/S'r 34 R, 34Lii are simultaneously excited. This is the fixed bin 30R with the L-shaped arm 27H.
#:r, pushed in the direction of arrow R by the outer end 39R of the elongated hole 32R provided in the horizontal guide member 31R, and the L-shaped arm is displaced clockwise around the fixed pin 29R. , therefore, the elongated hole 25 of the horizontal member 26 is also indicated by the arrow R.
, and press the switching lever 24a in the direction of the arrow R against the spring blade of the self-holding mechanism of the switching lever 24a.

In this way, the switching lever 24a is displaced from the second position to the third position. At this time, the electromagnetic first langeer 34L is also energized M1 at the same time, pulling the horizontal guide member in the direction of the arrow.

Even after the magnetic plunger is removed, the switching lever 24
Maintaining the state of the third position of the switching lever 24a and 1g6 is also the same as the above-mentioned item (31).
The state changes from the second position shown in Figure (C) to the third position shown in Figure s6 (A), and the switching of the switching lever 24a(1) from the second position to the third position is completed.

(6) When switching the switching lever 24a from the first position to the second position, in this case, the displacement force from the first position to the third position is mainly Due to the displacement force of plunger 34L.

The displacement force from the third position to the second position is the plunger 36L
1, and the switching lever 24a is displaced from the 2nd position to the 3rd position, and then to the 2nd position. With the above steps, switching of the switching lever 24a from the first position to the second position is completed.

(6) When switching the switching lever 24a from the i@2 position to the @1 position, this case is the same as the first operation in item (!), but the displacement force from the 2nd position to the 1@3 position is Mainly due to the displacement force of the plunger 34R, the displacement force from the third position to the first position tilt'-f is covered by the displacement force of the plunger 36R, and the displacement force from the second position to the third position of the switching lever 24a is covered by the displacement force of the plunger 36R. Then, it is further displaced to the first position. After that, the switching of the switching lever 24a from the second position to the first position is completed.

Here, one operation of the switching lever 24a, the director's desk A,
Therefore, the switching state of the director's telephone 8A is as shown in Table 2.

Table 2 also shows the correspondence between the type of switching lever 24a and the *magnetic plunger.

6 or less margins) Table 3' Figure 7 shows the display input means 7A placed on the director's desk A3.
3, the display input means arranged on other desks have the same circuit configuration.

The I/'i current power supply voltage is applied between the terminals P and N of the connection terminal plate TBI, and the control element 4 is applied via the line 39.41.
The voltage is applied between terminal VCC of 0 and 0. Line 39 is at medium potential and line 40#i0 potential. This circuit has a control input terminal IN of 40 control elements and a plurality of control output terminals OTI to OTn, and includes a reference voltage generation circuit and an input voltage generated at the control input terminal IN. and the reference voltage, and selectively outputs one of the output terminals OTI to OTn to a low level in accordance with the level of the input voltage. It has a comparator circuit, an arithmetic circuit, an output selection circuit, etc.

The reference voltage set inside the control element 40 is led to the terminal Vref of the control element 40, connected to the comparator input terminal R1 via the line 42, and connected to the terminal Vr.

Connected to 1.

Here, when none of the operation switches S] to S8 are pressed, the terminal R1 of the control element 40 is connected to the resistor R.
*i#i is zero flowing out through o, and therefore the potential difference between terminal IN and terminal RI is also zero. At this time, all of the control output terminals OTI to 0T8H are at a high level.

For example, when the operation switch SW2 is pressed, S2 is closed while it is pressed, and -'+ItlJ control element 4
Since the terminal R1 of 0 and the like 414j decoy resistor r01rl are connected, a current flows from the terminal R1 to the line 41, and the voltage of the terminal R1 to the line 41 changes to the base r! A is constant and equal to the voltage Vref, and the resistance is 1
0. Since rl is also a predetermined line, a voltage indicated by σ is applied between the terminal IN and the line. The reference voltage Vref of the control element 4o is compared with the voltage Vin(S2) of the formula fi+, and as a result, the corresponding control output terminal OT2 is selectively outputted as a low level. Similarly, when the operation switch S3 is pressed, the pressed quantity control manual terminal I
A negative voltage is applied between N and the line 41, and the corresponding control blade terminal OT3 becomes low level. The same applies when any other sh switch is pressed.

As shown in the diagram, the connecting terminal plate TBI Keyu 2 is also connected to the display manpower means 7A1 and 7A2, which are respectively arranged on the director's other desks AI and A2, via the display manpower control line CA. Therefore, the control input voltage Vin(Sn
) is also applied to the connection terminal W of the display input means 7A1, 7A2, and the control elements 4° in each display input means 7A1, 7A2 perform the same 1111 operation.

The control output terminals OTI to 0T81 of the control element 40 are connected to the σ resistors rbl to rb8, respectively, and the other ends of these resistors are connected to the bases of the transistors Q to Q8, respectively. Further, resistors rcl to rcs are connected to the bases of transistors Q1 to Q8, respectively, and the other ends of these resistors are all connected to line 39, and are at the power supply voltage level, that is, high level. In addition, a diode D1 is connected to the control output terminals OTI to OT8 of the control element 40.
The anode sides of these diodes are connected in common and connected to the base of a transistor Q9 via a resistor rb9, and a resistor rc9 is connected to the base of the transistor Q9. Connected to line 39.

The photoelectric charge σ of the capacitor Co is discharged through the relay coil RLIO, and the relay coil RL10i is discharged only during the discharge period.
Excited.

The relay switch r 110 interrupts the conduction between the line 42 and the line 41, which are conductive, for the period described above.

Relay switches rli to r18 are connected between the base and collector of the transistor QINQ8, and the common contacts and individual contacts of these relay switches become conductive when the corresponding relay coils are excited, and Encourage once! It releases a so-called self-holding circuit that maintains that state when it is turned on. Therefore, the relay switch rllO functions as a reset for the self-holding circuit.

Indicator lights P1 to P realized by F on light emitting diodes, etc.
8 is connected in parallel to the relay coil RLI-RL8 via a protective eel resistor r d I Nr d 8,
Each of these indicator lights is activated during the excitation period of the corresponding relay coil.
In other words, one point continues to appear during the self-preservation period. This is director's other desk AI, display human power means 7A1 placed on A2.
, 7A2 are also performed at the same time as described above. In addition, these indicator lights P1 to P8, the indicator lights PLI to P shown in the third figure
This corresponds to L8.

It lies at the connection point between each collector of the transistors Q1 to Q8 and one end of each of the relay coils RLI to RL8.

Each line 43-50 is #fPjeg individually.

These lines 43 to 50 are introduced into a diode matrix circuit 51 (the lower part of Fig. 147, surrounded by a virtual line), which will be described later, and organized into a circuit for driving the above-mentioned telephone switching means 10a. Terminals A and B of TB2
, C. In addition, the terminal P of the connection terminal board TB2,
A power supply voltage is applied through the N line 39 and 41. The above-mentioned telephone disconnection means Oa is connected to the connection terminal plate TB2 via the M filling machine switching control line DA shown in FIGS. 2 and 3.

Next, 11 works of the seventh (2) electric circuit will be explained.

Assume that the 1-operation switch Sl is pressed at time t1.

At this time, as described above, the control output terminal OTI of the control element 40 becomes a low level and triggers the base of the transistor Q9 via the diode DI, so that the transistor g9ij4mL.

Excitation current flows through relay RL9 and relay switch r19
is opened, and the common contact r19c and the individual contact r19b are opened; instead, the common contact r19c and the individual contact rlQa are closed. At this time, the charge of the capacitor Co is discharged through the relay coil RL10, and the relay coil is energized during the discharge period t2, and the relay switch r1]0
The pre-reset operation is performed after opening for the above-mentioned period t2. At the same time as the reset of the relay switch rllo ends, the base of the transistor Ql is also triggered by the output control terminal OTI like the base of the transistor Q9, so the transistor Q1 becomes conductive, the relay coil RLI is energized, and the relay switch rll closes and retains itself. Therefore, the indicator light PI continues to light up, and the power supply voltage is applied to the diode matrix circuit 51 via the line 39 - relay switch rll → line 43.
is derived. In this state, another operation switch Sn is pressed and the relay switch rll is reset.
will be maintained. In this embodiment, a relay is used to configure the self-holding circuit, but a semiconductor element such as a thyristor may be used to make the circuit non-contactable.

FIG. 8 is a time chart showing #f'V of each part during 871 operation of the electric circuit shown in FIG. 9M7. Figure 8 full
At time T1, the operation switch S] is suppressed for a time t1, and accordingly, FIG. 8 (1a) shows that the output control terminal OTI of the control element 40 outputs a low level.

Figure 8 (21c) At time T2, operation switch S2 is suppressed at time t4, @Figure 8 (2a) bottom output control terminal OT2
indicates that outputs low level. Figure 8 (3) shows that the transistor Q9 conducts for the above time tl, and as a result, the relay switch r19 is turned on in Figure 8 (3a). It is shown that the relay switch rllO is activated during the discharge period t to discharge through the coil RLIO. When the discharge time t2 has elapsed, the relay switch rllO is restored, and at the same time, the transistor Q1 becomes conductive for the time tl-t2 in FIG.
f As a result, the relay coil RLI is excited, the relay switch rll is activated, and thereafter it is shown to be self-holding at time T'2''! Therefore, the power supply voltage is derived to the line 43 in Section 8 (7). It is shown that the process continues until time T2.

The same goes for relay switch r12 and line 44.

FIG. 9 is an electrical circuit diagram of the diode matrix circuit 51 mentioned above. FIG. 9 forms a part of the electrical circuit diagram of FIG. 7, and corresponding parts are given the same reference numerals. Referring to Fig. 7, diode D43 in Fig. $9

The cathode of diode D44 is also connected to terminal B on line 5.
The cathodes of the diodes D45 to D50 are commonly connected together and connected to the terminal C1 via a line 54. According to this, the operation switch S
When 1 is pressed, terminal A.

l Output as 1g1 control voltage for HA operation. When operation switch S2 is suppressed, terminal B and N terminal are connected to N2.
Control voltage is output. When any one of the operation switches 83 to S8 is pressed, I! is applied between terminals C and N. 3 control voltages are output. Here, the control voltage is increased, and the switching lever 24a of the telephone switching means 10A is switched to the first position,
The second simple j control voltage switches the switching lever 24a to the second position.

This is for switching the switching lever 24a to the third position at a voltage of @3 mJa, and at this time the switching #J operation of the telephone shown in Table 2 above is performed. In addition, in Figure @9, the cathodes of diodes D45 to D50 are connected in common, so if an operation switch for a destination other than Buildings 1 to 3 is pressed (for example, press S6 to display "Meals"), the Director This is to connect the director's internal telephone communication line IA to the telephone 8A3 on the director's desk A3 when the director is absent from desks A1 to A3. This adds up to a telephone call 8A3 on the director's desk A3.1 For example, by providing a desk for the director's secretary near the director's desk A3, the response can be made appropriate and simple.

In this example, one 3-circuit converter was used as the switching means 10A, but if there are four or more switching points, 2-circuit or 3-circuit converters may be connected in series or parallel as appropriate. It's great if you put them together.

Next, one of these electrical circuit diagrams will be explained.

It is assumed that the switching lever 24aH is in the $3 position shown in the fifth figure.

When +111141 control voltage is applied between terminals A and N, terminal A - common contact rllllc - individual contact rllllb → relay coil RL12 → line 56 - path of terminal N, terminal A → diode Dll → common contact r115c - individual contact rl15b - relay coil RL 16 - line 56 - terminal N path is formed, and relay coil RL12. R

l16 is fIF, at.

In the relay switch rl12, the common contact rl12C and the individual contact rl12afsil are electrically connected.1 Individual contact rl]2b
is cut off, so capacitor CI is connected to relay switch r.
Relay coil RL17 via the seventh contact point of l12,
Furthermore, diode D]3. Relay coil RLI via D14 1. It is connected to RLI2. Therefore, since the charge force i of the capacitor C1 is discharged through these relay coils, both of the relay coils J are energized for the time a when the discharge of the capacitor C1 ends l. Therefore, for excitation of relay coil RLII, 2 relay switch r is used.
l11 is young and switched, and the application of the receptacle 1 control voltage is switched from the relay coil RL12 to the relay coil RLI1, and the relay fill RL11V'i enters a self-holding state by the i first control voltage. However, the signal 'MJ' of the control voltage to the relay coil RL12 is disconnected.

This is because the charge of the capacitor C1 flows through the diode DI4. Since the relay coil RL2 is not demagnetized and continues to be excited until the discharge of the capacitor C1 is completed, chattering of RLI2 does not occur. What?
Relay coil RL] Another relay switch r of 2
l12x operates ω1 to disconnect the relay coil RL20 for the discharge period.

Next, relay switch rl16 cuts off common contact r116c and individual contact rl16b, so capacitor C3
is connected to the relay coil RL19 via the contacts of the relay switch rl16, and further to the diode D17. It is connected to relay coils RL15 and RLI6 via D18.

Therefore, since the photoelectric charge of the capacitor C3 is discharged through these relay coils, both of the relay coils are excited at the time when the discharge of the capacitor C3 ends.

Therefore, the relay switch rl15 is activated and switched by the excitation of the relay coil RL15, and the application of the $1 control voltage is switched from the relay coil RL16 to the RLI5, and the relay coil RL15tj and the subsequent 141? ItlJ
The control voltage becomes 29 self-holding state. Relay coil RL1
The capacitor C3 is disconnected from the first control voltage to the capacitor C3.
Since the charged charge flows through the diode D18,
Since the relay coil RL16a is not immediately demagnetized and continues to be energized when the discharge of the capacitor C3 ends 1, no chattering occurs in the RLI6.

Therefore relay switch rl12. Since both rl16σ and rl16σ do not immediately recover and maintain their previous states, the relay coil RLI7. RLI 911:t are energized by capacitors C1 and C3, respectively, and relay switch rl17. rl19 is switched and connected to capacitor C4H solenoid coil P36R and capacitor C6ff solenoid coil p34H, so both solenoid coils are connected to the discharge current of the capacitor.
During this time, the electromagnetic plungers 34R and 36R are driven. This allows the above-mentioned I sea urchin switching lever to

b is shut off, so the relay coil RL18 is connected to the relay coil RL18 via the capacitor C2 or the contact point of the relay switch RL14.
Furthermore, relay coil RL13. It is connected to RL14. For this reason, the charge in the capacitor C2 is discharged through these relay coils, so the relay fills marked J are all connected to the capacitor C
It is excited only for the time until the end of discharge in step 2. Therefore, the excitation of the relay coil RL13 is caused by the relay switch rl.
13 is switched with an explosion 11, and the stamping point of the second control voltage is switched from relay coil RL14 to relay coil RLIa, and from relay coil RL14tj onward, the second control voltage becomes a self-holding state. Relay coil RL14
The @2 control voltage is no longer applied to the capacitor C2, but since the charge in the capacitor C2 flows in through the diode D16, the relay coil RL14 is not immediately extinguished and continues to be excited until the capacitor C2 is finished discharging. Therefore, RL1
4 chattering does not occur. In addition, relay coil RL
Another relay switch rl14x of I4 is activated to disconnect the relay coil RL19 for the discharge period.

Next, the relay switch rl16 is cut off between the common contact r116c and the individual contact rl16b, so the capacitor C3
is connected to the relay coil RL20 via the contact point t of the relay switch rl16, and further to the relay coils RL15 and RL]6 via the diode I)17,018. As a result, the photoelectric charge of the capacitor C3 is discharged through these relay fills, so that both of the relay coils are energized for a period of time until the discharge of the capacitor C3 is completed.

Then, the relay switch RL15 is activated and switched by the excitation of the relay coil RL15, and the inlet of the second control voltage is switched from the relay coil RL16 to RL15. to 2

When capacitor C2 finishes discharging, relay coil RL

Since the solenoid coils P34L and P34R are connected to each other, both the solenoid coils P34L and P34R are excited by the discharge current of the capacitor C6, during which time the electromagnetic plungers 34L and 34R are driven. As a result, the switching lever 24a is displaced to the 3rd position as described above.

When capacitor C3 finishes discharging, relay coil RL16

Second, in this example, since the discharge of the capacitor is used to drive the electromagnetic plunger, there is no need to supply a large current through the switching control line DA, and the wire diameter is also small. It's 2. In addition, although a relay was used to switch between charging and discharging in this embodiment, it is also possible to use a semiconductor element such as Cyrisk to make the circuit contactless. .

In this embodiment, the 11IO operation of the telephone switching means 10A placed on the director's desk A3 has been described, but in this embodiment, the telephone switching means 10B placed on the assistant director's desk B3 is One version of the telephone switching means 10C placed on the factory manager's desk C3 is also exactly the same as the earlier version of the telephone switching means IOA.

This figure is similar to Figure 2, and corresponding parts are given the same reference numerals. @1 Since the manager has one less desk than the director's desk AX, the display input means 7 and 8 telephones are the same, except that the diode matrix circuit and If telephone switching means 10D are slightly different. is used.

It is a circuit diagram of a diode matrix circuit 51a housed in display human power means 7D1 and 7D3 arranged at the desk of the manager 12A. The first manager's desk is one less than the director's desk in 2 above, desk D1 in Building 1 and desk D3 in Building 3, so the 6th desk is Building 1.

This switching lever 60a#'? protrudes outward from 0b (cubic in FIG. 5). . The third position in the vertical state shown in Figure 13 and the direction indicated by arrow R (to the right in Figure 113)
There are two types of modes in which the first position is angularly displaced in the direction of the arrow R by the sword applied to the blade. When the switching lever 60a is at the $3 position, the line /Dσ and the line /D3
When in the first position, it is selectively connected to the telephone 8D3 via the telephone 8D3, and to the telephone 8Dl via the 8 line/D line/DI, respectively.

A horizontal member 62 is arranged at the bottom of the housing 60b facing the switching lever 60a, and a slotted hole 61 is provided in the center of the horizontal member 62.
It is loosely inserted inside. One end of the horizontal member 62 is connected to the plunger 63R of the plunger 65R by a pin 64RIC, and the other end is connected to the plunger 63L of the electromagnetic plunger 65L by a pin 64L. Here, when all of the electromagnetic plungers t are energized, they attract the plunger 1 into the solenoid. This is a so-called pull-type electromagnetic plunger.

If the switching lever 60a is now in the third position shown in the drawer 13, when the electromagnetic plunger 65R is excited, it will move in the direction shown by the arrow R in Fig. The horizontal member 621
Therefore, the elongated hole 61σ is displaced in the direction of the arrow R and presses the switching lever 60a in the direction of the arrow R, and in response, the switching lever 60atj is angularly displaced in the direction of the arrow R and $1
Even after the electromagnetic plunger 65R is cleaned, the state of the first position is maintained by the self-holding mechanism, and the switching of the switching lever 60a from the third position to the first position is completed.

Next, the construction of this electric circuit diagram will be explained.

It is assumed that the switching lever 60aF'i is in the s3 position shown in the twelfth figure.

When the first control voltage IIII is applied between terminals I and 8 (indicating that the connection destination is terminal AI in FIG. 12A and terminal B in FIG. 12B), relay coil RL2I is energized M1,
Relay switch r121 is created, common contact r121c
and the individual contact r121a are electrically connected, the capacitor C7 and the solenoid coil P65R are connected, and the charge WIIW & load of the capacitor C7 is discharged through the solenoid coil P65R, and the solenoid coil P65R is energized only for this discharge time.

*The i-plunger 65R is activated. As a result, the aforementioned switching lever 60a is displaced to the IB1 position.

Relay coil RL21 continues to be excited by the first control voltage, so common contact r121c and individual contact r12
1a and σ conduction state is maintained, but when the capacitor C7 finishes discharging, the solenoid coil P65R is demagnetized,
The electromagnetic plunger 65Rσ becomes free.

When +21@3 control voltage is applied between terminals C and N.

The first control voltage becomes zero, the relay coil RL21 is turned off, the relay switch r121 is restored, and the capacitor C7 is charged again through the resistor r21.

2 relay coil RL22 is energized at 0 of the third control turtle pressure, and relay switch r122 is activated.

The common contact r122c and the individual contact r122a are electrically connected.
