Abstract

The switch includes a housing and second rotors for opening and closing cooperable contacts. A third rotor restricts the rotation of the second rotor under a certain condition. All the rotors are disposed in axial alignment with each other. The first and second rotors are urged to rotate in one direction while the third rotor is urged to rotate in the other direction by the action of a force greater than that urging the second rotor to rotate in the one direction. A pushbutton is disposed between the first and second rotors and acts, when depressed, to forcedly rotate them in the other direction so as to establish a loudspeaker receiving circuit.

Yaha, embodiments of the present invention will be described in detail according to the accompanying drawings.

1 to 9 show a first embodiment of the present invention. This embodiment relates to an example in which the switch of the present invention is applied as a hook switch of a telephone.

FIG. 1 is a plan view of a synthetic resin housing 1 in which a cover 1 made of synthetic resin (shown in FIG. 2) is removed and an internal mechanism is exposed.

In the housing 2, rotor chambers 4 and 5 are formed on the left and right sides of the central chamber with narrow narrow chambers 3 therebetween, and a part of the housing 2 is external to the outside of the rotor chamber 5 on the right side. The third rotor chamber 6 which is open at the top is formed. In the rotor chambers 4, 5 and 6, respectively, the rotors 8, 9 and 10 made of synthetic resin are installed so as to be rotatable in a coaxial state, but the first rotor 8 and the second rotor are installed. (9) is a switch for controlling the required on and off by the rotation operation, in the description of this embodiment applied to the telephone, the first rotor (8) for on / off control for the speaker hydration function The rotor and the second rotor 9 are on / off control rotors for the network function. The third rotor 10 is rotated in conjunction with the ringing and falling of the handset (not shown), and regulates the rotation of the second rotor 9. The first rotor 8 and the second rotor 9 come into contact with each other by the rotation of the fixed terminal 11 and the movable terminal 12 as shown in FIG. 2 (on / off). The cam projection piece 13 is expanded to the rotor circumferential surface for this welding. However, the number of switch contacts to be turned on and off by the respective rotors 8 and 9, and the number and shape arrangement of the cam protrusions 13 are individual design matters corresponding to the electric apparatus using the switch, and Since it is not the gist of the present invention, the description is omitted, and only the fixed terminal 11 and the window operating holes 14 and 15 of the movable terminal 12 are shown in FIG.

In the first rotor 8, as shown in FIG. 4, a circular receiving portion 8b extending from the side surface in the axial direction is formed at an end opposite to the second rotor 9, The accommodating portion 8b houses a coil spring 16 that rotates the first rotor 8 in the direction of the arrow a. The second rotor 9 has a first rotor At the opposite end, a circular accommodating portion extending in the axially inward direction from the side surface, which is similar to the accommodating portion 8b of the first rotor 8, is formed, and this accommodating portion is provided with the second rotor 9. The coil spring 17 which rotates in the direction of arrow a is accommodated, and the third rotor 10 is shown in FIG. 7 at an end opposite to the second rotor 9. Similarly, a circular accommodating portion 10b extending from the side surface in the axially inward direction is formed, and the third rotor 10 is rotated in the direction of arrow b in the accommodating portion 10b. The coil spring 34 to be fully charged is accommodated. In this way, when the coil springs 16, 17, 34 are accommodated in the rotors 8, 9, 19, respectively, the space for installing the coil springs in the housing does not have to be formed separately, and the housing 2 Furthermore, not only can the whole switch be miniaturized, but the number of turns of the coil spring can be increased without affecting the installation space, and the secondary force of the coil spring can be maintained for a long time.

In addition, in the present embodiment, in order to further downsize the entire switch to the housing 2, as shown in FIGS. 4 and 7, the accommodating portion of the accommodating portion of the accommodating portion of the second rotor 9 is shown. The rotary shaft portion 9a longer than the axial length of the third rotor 10 is integrally protruded at a predetermined distance from the inner circumferential surface, and the coil spring 17 is covered with the end of the rotary shaft portion 9a. The housing 10b of the third rotor 10 is received from the side of the end portion of the second rotor 9 at the center portion of the third rotation 10 while being accommodated in the housing portion of the second rotation 9. ) And a rotation shaft portion 9a of the second rotor 9 is rotated from the insertion passage 10c to the receiving portion 10b of the third rotor 10 from the insertion passage 10c. Inserting the coil spring 34 on the end of the rotating shaft portion 9a protruding from the receiving portion 10b of the third rotor 10, The end of the rotating shaft portion 9a protruding from the receiving portion 10b of the third rotor 10 to the outer wall 2b of the housing 2. To support it.

In addition, as shown in Figs. 1 and 4, the first and second rotors 8 and 9 have opposite rotational end portions 8d that protrude in opposite directions as shown in Figs. 9d) is integrally formed, so that it intrudes into the chamber 3, in particular, the hydraulic tongue pieces 18 and 19 are integrally formed in the indentation tip, and further, in the chamber 3; In this case, the pushbutton 20 is arranged on the upper end surface of these hydraulic tongue pieces 18 and 19. The relation between the pushbutton 20 and the hydraulic tongues 18 and 19 is as shown in FIG. 5, and the hydraulic tongues 18 and 19 are connected to the base end 21 of the pushbutton 20. The solid line posture which the end part contacted and pushed this pushbutton 20 to the non-pressing position by the rotational bias force of the one direction provided by the coil spring 16 and 17 already demonstrated to a normal state is brought to the normal state. As the pushbutton 20 is pressed down, the first and second rotors 8 and 9 are forcibly rotated through the rotation shafts 8d and 9d.

In addition, the pushbutton 20 is moved to the non-pressurized position via the rotating shaft portions 8d and 9d and the hydraulic tongue pieces 18 and 19 by the rotational force in one direction applied to the coil springs 16 and 17. I'm trying to get it back. Then, the first rotor 8 in charge of the loudspeaker hydration function opens the loudspeaker hydration circuit (which enables hydration) by this forced reverse rotation, and the second rotor 9 in charge of the network function is a network circuit. Open (make callable).

The pushbutton 20 is equipped with a Haatcam mechanism which is first pushed down, and this pushed down state is locked, and is pushed down again to unlock and return. This function includes a Haat cam groove 22 formed in the shaft portion of the pushbutton 20 and a lock pin 23 into which the tip is indented. The operation of the pushbutton 20 will be described with reference to FIGS. 6A and 6B. When the 20 is pushed down from the initial state at the top dead center, the lock pin 23 is relatively raised, the ascending groove 24 in the Haat cam groove 22 is raised and the push button is moved to the bottom dead center. At this time, it returns to the inclined groove part 26 with the step | step 25 with respect to the rising groove part 24, and the lock pin 23 rotates by one rotation and descend | falls the inclined groove part 23 as the next press release is released. The groove engages the generally U-shaped valley 28 deepened by the step 27 to prevent the return of the pushbutton 20 from rising. Therefore, this lock position is halfway between the top dead center and the bottom dead center. When pushed down, the lock pin 23 exits the valley 28 upwards and enters the downward groove 30 having the step 29 with respect to the valley 28, and thus the downward groove 30 according to the release of the depression. The lowering step passes the step 31 and enters the original rising groove 24. It goes without saying that each of the steps 25, 27, 29 and 31 is for dynamic stop of the lock pin 23.

As shown in FIG. 1, the lock pin 23 is provided in parallel with the rotatable chamber 5 in which the second rotor 9 is housed, and a passage hole 32 whose front end is formed in the housing partition wall. Is inserted into the Haatcam groove 22, and the other end, the special pin head portion 23a is pushed out through the housing outer wall 2a, and the pin head portion 23a is removed. As is apparent from Fig. 4, it is formed in a T shape. The lock pin 23 is covered with a coil spring 33 for biasing the rush into the Haat cam groove 22, and one end of the spring has a small shaft diameter portion 23b at the end of the pin (FIG. 4). The other end abuts on the housing outer wall 2a. In addition, when the lock pin 23 performs the above-described lock and unlocking operation, the lock pin 23 not only shakes in the retreat direction, but also shakes in the transverse direction, so that the through hole 32 of the lock pin 23 does not prevent the shake. It is of a size that can afford to the shaft diameter.

The third rotor 10 is a coil spring 34, which has a rotational bias force in a direction opposite to the second rotor 9 as shown by the arrow 4 in FIG. At the same time, the engaging projection ends 35 and 36 for engaging both rotors 9 and 10 as opposite rotational biases are formed as shown in FIG. The second rotor 9 has a structure in which the second rotor 9 receives rotational force of the opposite direction of the third rotor 10 and rotates together.

The third rotor 10 is integrally provided with a first input lever 37 for switching the rotation in conjunction with raising and lowering of the handset. That is, as shown in the third diagram, the rotary shaft 39 is extended to the base set 38, and the rotary shaft 39 has a handle 40 and a first input lever that cooperate with the raising and lowering of the handset. 37) and the set lever 41 engaging from the lower side are installed, and when the handset is placed on the base set 38, the handle 40 is lowered so that the set lever 41 removes the first input lever 37. In the state of pushing the 7-degree solid line, on the contrary, when the handset is removed from the base set 38, the handle 40 is raised, and the coil spring (1) in which the first input lever 37 is built in the third rotor 10 ( The negative force of 34) is to go down with the dashed line of FIG. 42, 42 shows a push button for call start. The first input lever 37 is formed with a cam portion 43 having a substantially C-shape in plan view, and the cam portion 43 has a horizontally collapsed peak having a tapered surface in the upper and lower sides of its open ends. The tapered cam surfaces 44 and 45 of the mountain shape are formed, and the T-shaped shape of the lock pin 23 described above during the rotational trajectory of the tapered cam surfaces 44 and 45 during the rotation operation of the input lever 37. The upper head 23a is configured to be located. Accordingly, in accordance with the rotation of the input lever 37, the tapered cam surfaces 44 and 45 abut against the T-shaped head portion 23a from the top or from the bottom, and the tapered cam surfaces 44 and 45 The lock pin 23 is slid in the direction to be pulled out of the Haatcam groove 22 against the coil spring 33, so that the T-shaped head portion 23a rides over the taper cam surfaces 44 and 45 to lock the pin. 23 doubles. In addition, the extraction of the lock pin 23 causes unlocking of the pushbutton 20. Therefore, in order to realize the release of the lock pin 23 accurately and at high speed with a slight slide of the lock pin 23, as shown in FIG. Likewise, it is preferable to apply a horizontal movement from the valleys 28 of the lock pin 23 toward the descending groove 30. Therefore, the taper cam surfaces 44 and 45 are not positioned at right angles to the lock pin 23 as shown in FIGS. 7 and 8, but are inclined as shown by the arrow C and the lock pin 23 is disposed. Shake it horizontally according to the contact of. In addition, the horizontally swinging structure makes it possible to release the lock without sliding the lock pin 23.

Next, the operation will be described. In the non-call state in which the handset is placed on the base set 38, the first input lever 37 interlocking with the handle 40 is raised, and the third rotor 10 is the coil spring 34. Is rotated against the rotational force in the reverse direction by the rotational force, so that the second rotor 9 is one side by the coil spring 17 without the pressure of the rotational force in the reverse direction with respect to the second rotor 9. Since only the force of the rotating part in the direction is set and is set in the same posture as the first rotor 8, the hydraulic tongues 18 and 19 of the first and second rotors 8 and 9 are ninth (a). Both push the push button 20 as shown. In this state, the speaker receiver circuit is closed and the network circuit is closed.

Next, when the pushbutton 20 is pushed down, the pushbutton is locked by the lock pin 23 and at the same time, each hydraulic tongue 18 and 19 is pressed down as shown in FIG. The two rotors 8 and 9 rotate to open the speaker receiver circuit and the network circuit, so that call oscillation is possible. In this way, since the network circuit is opened with the handset placed on the base set 38, the call oscillation operation can be performed by one hand operation.

When the connection with the other party is established, confirming that the audio signal comes from the speaker (not shown), and picking up the handset, the input lever 37 and the third rotor 10 are coil springs 34. Rotate force in the reverse direction by means of rotation at a time, but at that time, the taper cam surface 44, 45 touches the head portion 23a of the lock pin 23 from above, and slides this lock pin back and also swings laterally. Since the lock of the pushbutton 20 is released, this pushbutton rises and returns, and at the same time, the first rotor 8 rotates and returns to close the speaker receiving circuit. However, since the rotational force of the reverse direction of the third rotor 10 is set to the strength that overcomes the rotational force of one direction of the second rotor 9, the rotation is engaged by the rotation of the third rotor 10. The second rotor 9 having the protruding end portions 35 and 36 re-engaged with each other is blown even though the pushbutton 20 is raised and returned, and does not follow the rotation of the first rotor 8 as shown in FIG. 9C. As a result, the network circuit remains open so that calls by the handset are maintained.

After the end of the call, the handset is returned to the base set 38 so that the second and third rotors 9 and 10 are rotated as intact, so that both the speaker signal circuit and the network circuit are closed. It becomes the initial state.

At the call of the other party, when the handset is picked up, it is in the state of FIG. 9C and only the network circuit is opened.

As described in detail above, when the switch of the above embodiment is used as an on / off control switch of a speaker handset circuit and a network circuit of a telephone, for example, by pressing the pushbutton while the handset is placed on the base set, the switch is pressed. By rotating both the first and second rotors for contact on / off control in the on direction, both the speaker receiver circuit and the network circuit are opened, and the call oscillation operation is possible with the handset placed on the base set. If the handset is picked up after contact with the other side, the input lever which rotates in conjunction with the picked-up operation releases the lock state of the lock pin to the pushbutton by the cam portion, and closes the speaker receiver circuit. The third rotor, which is integrally rotated with the input lever, prevents the return of the second rotor and keeps opening the network circuit. Therefore, call oscillation can be performed by one-handed operation, and only the speaker sign circuit can be closed by picking up the handset. In addition, since this function is achieved by the mechanism mechanism, it is inexpensive and can be easily installed in the base set, thus eliminating the need for a large control box as in the prior art, and affecting the direct use voltage and current of the telephone. The function can be added without receiving.

10 to 17a to 17f show a second embodiment of the present invention. This embodiment is applied to the hook switch of the telephone as in the first embodiment, but in particular, the switch of this embodiment has a call hold function in addition to the speaker sign language function of the first embodiment. . This switch will be described in detail below. In addition, in the detailed description about this, and in FIGS. 10-17a-17f, the same part as the said 1st Example (FIGS.-9a, 9b, 9c) is shown. have.

FIG. 10 is a plan view of the housing 102 in which the inner structure is exposed by removing the cover 101 made of synthetic resin (shown in FIG. 11).

Four rotor chambers 103, 4, 5, 6 are formed in the housing 102 from the left side to the right side of the drawing, and between the fourth rotor chamber 103 and the first rotor chamber 4. And small chambers 107 and 3 are formed between the first rotor chamber 4 and the second rotor chamber 5, respectively. In the rotor chambers 103, 4, 5 and 6, rotors 109, 8, 9 and 10 made of synthetic resin are respectively mounted in the housing 102 so as to be rotatable in a coaxial state. Four rotors 109 are on / off control rotors for call holding function, the first rotor 8 is on / off control rotors for speaker hydration function, and second rotor 9 is network function Rotor for on / off control. Similar to the sixth embodiment, the third rotor 10 is rotated in conjunction with raising and lowering the handset (not shown), and restricts rotation of the second rotor 9. Similarly to the first embodiment, the fourth rotor 109 also contacts (on / off) the fixed terminal 113 and the movable terminal 114 as shown in FIG. 11 according to the rotation thereof. For this contact, the cam-dol piece 115 is expanded on the circumferential surface of the rotor. However, the number of switch contacts turned on and off by the fourth rotor 109, and the number, shape, and arrangement of the cam protrusion pieces 115 vary depending on the respective functions, and individual design matters according to the electric apparatus using the switch. In addition, since it is not the summary of this invention, description is abbreviate | omitted and only the hole 116 and 117 for attachment of the fixed terminal 113 and the movable terminal 114 are shown in FIG. .

At the end opposite to the first rotor 8, the fourth rotor 109 is formed with a circular accommodating portion 109b (see FIG. 13) extending in the axial direction from the side surface thereof. The coil spring 118 which rotates this 4th rotor 109 in the direction of arrow a is accommodated in 109b. Moreover, the rotating shaft part 109d which protrudes toward the 1st rotor 8 integrally formed from the other end side surface of the 4th rotor 109 is turned to the loss | disappearance 107, and the edge part of the rotating shaft part 109d is carried out. The hydraulic tongue piece 121 is integrally formed at the upper side, and the pushbutton 124 is disposed on the upper end surface of the hydraulic tongue piece 121. The push button 124 mounted on the chamber 107 is for call holding, and as shown in FIGS. 17A to 17F, the hydraulic tongue 121 of the fourth rotor 109 is a push button for call holding. The pusher button 124 is pushed down in contact with the base end of 124 and in a normal state in which the button is pushed up to an ascending position by the rotational force in one direction given by the coil spring 118 described above. Accordingly, the fourth rotor 109 is forcedly reversed through the hydraulic tongue piece 121. Then, the fourth rotor 109 in charge of the call holding function opens the call holding circuit with this forced reverse rotation (holds the call on hold).

In addition, the push button 124 for call holding has a Haatcam mechanism that is locked in the depressed state by the first depressing and released by the depressing again. That is, it includes a Haat cam groove 126 impregnated in one side of the push button 124 for call holding and a lock pin 127 in which the tip portion is indented, and the push button 124 is shown in FIG. When pushed down from the initial state at the top dead center, the lock pin 127 relatively rises, and ascends the rising groove 128 in the heart cam groove 126, and the rising groove 128 when the push button reaches the bottom dead center. ) Into the inclined groove 130 having a step 129, the lock pin 127 is rotated once to descend the inclined groove 130 in accordance with the depressing release, and further grooves in the step 131. By engaging with the generally U-shaped bone portion 132 deepened by the restraining rise of the push button 124. Therefore, this lock position is halfway between the top dead center and the bottom dead center. When pushed down again, the lock pin 127 exits the valley 132 upward and enters the downward groove 134 having the step 133 with respect to the valley, thereby pushing down the groove 134 according to the release of the depression. It descends and enters the original upper groove 128 through the step 135. In addition, it is a matter of course that each of the steps 129, 131, 133, 135 is for the reverse stop of the lock pin 127.

자형상의 금구로서, 제13도 제15도와 같이 지지판(136)의 원형구멍(137)에 하단부(127a)를, 원호형상의 긴구명(138)에 상단부(127b)를 끼우고, 이 하단부를 지점으로해서 좌우로 회동할 수 있게 해서, 이 지지판(136)을 하우징(102)의 홈(139)에 삽입하여 하아트캠홈(126)에 대면시키며, 또한 지지판 배면부의 하우징격벽(102c)에 의해서 록크핀(127)의 빠져나감을 저지한 상태에서 상단부(127b)를 하아트캠홈(126)에 돌입시키고 있다. 이와같이 록크핀(127)을 좌우방향으로 회동 가능하게 하는것은, 이 핀이 상승홈부(128)와 하강홈부(134)에 걸치 가로이동을 행하지 않으면 안되기 때문이다.The lock pin 127 is generally

As the female bracket, as shown in FIG. 13 and FIG. 15, the lower end 127a is inserted into the circular hole 137 of the support plate 136, and the upper end 127b is inserted into the arc-shaped long life 138. The support plate 136 is inserted into the groove 139 of the housing 102 so as to face the Haatcam groove 126, and is locked by the housing partition wall 102c of the support plate rear portion. The upper end portion 127b enters the Haatcam groove 126 while preventing the pin 127 from escaping. The locking pin 127 can be rotated in the left and right directions in this way because the pin must move horizontally over the rising groove 128 and the falling groove 134.

The Haatcam furniture and lock pin 23 of the pushbutton 20 for speaker hydration and network are the same as those of the first embodiment.

In addition, the push button 124 for call holding is integrally formed with an arm 148 which protrudes out of the housing in a state where the button is accommodated in the housing 102 and at the outer side of the housing 102. A second input lever 149 pivots around the support side 152 at a position near the protruding arm 148. The second input lever 149 is provided with a hook click 150 on the pivotal base thereof, which can be pushed out of the slide trajectory of the arm 148 on which the push button 124 is integrally raised and lowered. The rotational force in the direction in which the direction deviates from the slide trajectory is applied to the second input lever 149 by the coil spring 151.

The relationship between the arm 148 and the hook click 150 is as follows. When the push button 124 is in the top dead center position, the hook click 150 is moved downwards without hitting the arm 148. When the pushbutton 124 is in the locked position, the hook-click 150 engages with the upper surface of the arm 148 to enter the slide trajectory. The tapered surface 148a formed on the arm 148 is a cutout formed to allow passage therethrough.

As shown in FIG. 12, a shaft main body 39, which rotates in association with the raising and lowering of the handset, is supported in the main body of the telephone, and the two input levers 37 from the shaft main body 39 are supported. The set lever 155 engaged with any one from below is installed at 149. When the hand set is placed on the base set 38, the handle 40 is lowered, so that the set lever 155 is the two input lever 37. 149, and on the contrary, when the handset is removed from the base set 38, the handle 40 is raised so that each of the input levers 37 and 149 is subjected to the force of the coil springs 34 and 151. Configured to descend.

Next, the operation will be described. In the non-call state in which the handset is placed on the base set 38, all of the input levers 37 and 149 linked to the handle 40 are raised, and the third rotor 10 It is in the position rotated against the rotating part force of the reverse direction by the coil spring 34, Therefore, the 2nd rotor 9 receives only the rotating part force of one direction by its coil spring 17, and the 1st rotor Since the hydraulic pressure pieces 18 and 19 of the first and second rotors 8 and 9 are all pushed up the pushbutton 20 as shown in Fig. 17A, have. In this state, the speaker receiving circuit and the network circuit are closed. In addition, the hook click 150 of the input lever 149 enters into the slide trajectory under the arm 148, and the hydraulic pressure piece 121 of the fourth rotor 109 pushes the push button 124 to the coil spring. At the same time pushing up with a force of 118, the integrated hold circuit is also closed.

Next, when the speaker hydration pushbutton 20 is pushed out, the button is locked by the lock pin 23 and at the same time, the first and second rotors 8 and 9 rotate as shown in FIG. 17B, The loudspeaker sign circuit and network circuits open, allowing call origination. In this way, since the network circuit is opened with the handset placed on the base set 38, the call oscillation operation can be performed by one hand operation.

When the connection with the other party is made and the audio signal is confirmed to come from the speaker (not shown), and the handset is picked up, the input lever 37 and the third rotor 10 are driven by the coil spring 34. While rotating in reverse direction at one time, the tapered cam surfaces 44 and 45 abut against the head 23a of the lock pin 23 from above and release the lock of the pushbutton 20. Therefore, this button At the same time as the rising and returning, the first rotor 8 rotates and the speaker receiving circuit is closed. However, since the rotational force of the reverse direction of the third rotor 10 is set to the strength that overcomes the rotational force of one direction of the second rotor 9, it is engaged by the rotation of the third rotor 10. The second rotor 9 in which the protruding end portions 35 and 36 are re-engaged with each other does not follow the rotation of the first rotor 8 as shown in FIG. 17C even though the push button 20 has been raised and returned. In this case, the network circuit remains open and the call can be made. The hook click 150 of the input lever 149 escapes from the slide trajectory of the arm 148 to allow the push button 124 for call holding to be pushed down.

When the push button 124 for holding is pressed in the middle of a call, this button is locked, and the 4th rotor 109 rotates like FIG. 17 (d), and a call hold circuit is opened. Then, the handset is placed on the base set 38, and the input levers 37 and 149 are raised so that the third rotor 10 is forcedly reversed as shown in 17 (e). ) Is released and the network circuit is closed by the return of the second rotor. On the other hand, the hook click 150 of the input lever 149 enters the slide trajectory of the arm 148, engages with the arm 148 at the lock position (Fig. 16 dashed line position) from above, and push button 124. Is pressed to the bottom dead center (16th dashed line position). Therefore, the lock of the push button 124 is released, but since the pushed down state of the button is maintained, the return rotation of the fourth rotor 109 is not made and the network circuit maintains the call holding state. When the handset is picked up again, the input levers 37 and 149 are lowered, and the third rotor 10 rotates the second rotor 9 together to open a network circuit (figure 10 (f)). Maintain currency. In addition, since the push button 124 is released by the hook-click 150, the restraint is lifted, the call holding circuit is closed, and the handset is returned to the base set 53 upon completion of the call. Is set.

In addition, when the handset is picked up by the call of the other party, only the network circuit is opened in the state of FIG. 17C.

As described above, according to the switch of this embodiment, the push button is pressed to hold the call in a call state, and afterwards, the rotating part of the input lever presses this button by returning the handset to the base set. By pressing until the lock is released and the call is held, the call can be secured when the handset is picked up again. In addition, since the call holding function and the speaker sign language function have been achieved as a mechanism mechanism, it is inexpensive and can be easily integrated into the base set, thus eliminating the need for a large control box as in the prior art, and the direct operation of the telephone. The plural functions can be added without being affected by the voltage and current used.

In addition, in Figs. 10 and 12, the call holding circuit is integrally assembled together with the network circuit and the spiker sign language circuit, but the call holding function portion may be assembled and operated in a separate housing.
