JPS63108841A - Telephone set with automatic holding function - Google Patents

Abstract

PURPOSE:To automatically hold a line in calling, by providing a sensor turned off when a handset is grasped with a normal posture by a caller, and turned on when it is separated from a caller's hand and laid in a horizontal direction. CONSTITUTION:When the caller hooks off the handset 1 from the telephone set main body, a state goes to an OFF-hook state, and a mode switching circuit 8a and a holding circuit 8 go to operating states, however, by grasping the handset 1 with the normal posture by the caller, the output signal of a handset grasp sensor 1a is turned OFF, thereby, the holding mode of the holding circuit 8 is canceled. Next, by separating the handset 1 from the caller's hand, the output signal of the sensor 1a is turned ON, thereby, the holding circuit 8 goes to the holding mode, then, a telephone line is held. Furthermore, if the handset is grasped again to continue the call, the holding state is canceled.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a telephone set having a function of putting a telephone line in use on hold.

(Prior Art) In conventional telephones with a hold function, in order to put the telephone line on hold during a call, the user presses a hold button provided on the telephone body and places the handset on the hook switch of the telephone body. To start a call again, it was necessary to lift the handset from the hook switch (hereinafter referred to as off-hook) and then press the button for the line in use.

(Problem to be Solved by the Invention) However, as mentioned above, when putting a telephone line in use on hold, the person on hold presses the button, and to release the call from hold, the line in use must press the button. The operation is cumbersome because the handset does not go on-hook, and it is necessary to put the handset on-hook after pressing the hold button, but there is a general concept that when on-hook, the telephone line is disconnected, so if you do not perform on-hook operation, if you go on-hook, , No.1
Since the handset is placed on the phone itself, it is difficult for people other than the caller to know that the call is on hold.

The present invention solves the conventional technical and handling problems as described above, and automatically puts a telephone line in use on hold without performing any operations such as pressing the hold button. The purpose of the present invention is to provide a telephone with a hold function that allows users to hold calls.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a holding circuit that puts a telephone line in use on hold in the main body of the telephone, and switches the operation mode of the holding circuit. In addition to providing a mode switching circuit, the handset is provided with a handset grip sensor that detects whether or not the handset is being held.
The output of the handset grip sensor is connected to the mode switching circuit, and when off-hook, the mode switching circuit receives the output signal of the handset grip sensor, and when the handset is not gripped, the hold circuit is switched to the hold mode. The system is configured to release the hold mode of the hold circuit when the handset is held, so that the hold button and the line button are not pressed alternately like in conventional phones with a hold function, but automatically. A device that allows a call to be put on hold or released from hold.

(Function) In the present invention, the handset grip sensor provided in the handset is a general on/off switch, and can be selected from among microswitches, photoelectric switches, mercury switches, etc.; In use, the output signal is such that it is off when the caller is holding the handset in a normal position and turns on when the caller removes the handset and places it on its side.

When the caller first picks up the handset from the telephone and goes off-hook, the hold circuit and mode switching circuit enter the operating state, but since the caller is holding the handset, the output signal from the handset grip sensor is When off, the hold circuit is taken out of hold mode. When the caller takes the handset away from his/her hand, the output signal of the handset grip sensor turns on), and the hold circuit is placed in hold mode via the mode switching circuit, so the telephone line is automatically switched on. It will be on hold. When the caller picks up the handset again and holds the handset in a normal posture, the output signal of the handset grip sensor is turned off and the hold mode of the hold circuit is automatically released, so that the call can be made.

(Example) FIG. 1 is a block diagram of one embodiment of the present invention.

In Fig. 1, 1 is a 71 handset, 1m is a handset grip sensor, 2 is a calling circuit, 3 is a sounder, 4 is an incoming call circuit, 5 is a dial, 6 is a calling circuit, 7 is a hook switch, 8 is a hold circuit, 8& is a mode switching circuit.

FIG. 2 is an external view of an example of a handset.

In FIG. 2, the symbols are the same as in FIG. 1. This shows the case where a microswitch is used as the handset grip sensor 1&, and the actuator portion of the microswitch is shown protruding.

An embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG. In this embodiment, the handset grip sensor 1a
As mentioned above, when using a microswitch, the handset 1 is placed in a position where it is always held when talking in a normal posture.When the handset 1 is gripped, the actuator of the microswitch is pressed, the contact opens, and the output is output. The signal is turned off, and when the handset 1 is released from the hand, the actuator of the microswitch is released from being suppressed, the contact is closed, and the output signal is turned on. The output of the handset grip sensor Ia is connected to the mode switching circuit 8a provided in the telephone main body, and the mode switching circuit 8a switches the operation mode of the hold circuit.

Now, when the caller picks up the handset 1 from the telephone body, it goes into an off-hook state and the mode switching circuit 8a and the hold circuit 8 are activated. However, when the caller holds the handset 1 in a normal posture, Handset grip sensor Ja
Since the output signal of is off, the hold mode of the hold circuit 8 is released and a call can be made. Next, when the caller releases the handset 1 from his/her hand, the output signal of the handset grip sensor 1a is turned on, and the hold circuit 8 enters the hold mode, so that the telephone line is put on hold. To continue the call, if you press ndset 1 again, the hold will be released.

In the above embodiment, a microswitch is used as the handset grip sensor 1m, and the actuator of the microswitch is provided so as to protrude from the back of the handset 1, but in carrying out the present invention, it is limited to microswitches. Instead, a switch element, such as a photoelectric switch, which operates equivalently as a handset grip sensor can be used. Furthermore, in order to ensure operation, a plurality of sensors may be provided on the grip υ of the handset l.

In addition, since the handset 1 is usually held vertically and used with the earpiece facing upward and the mouthpiece facing downward, a mercury switch is used as the handset grip sensor 1a, and the hide set 1 is held vertically. When the mercury switch is placed in the horizontal direction, it is assumed that the hand is held in the hand, and when the handset 1 is placed in the horizontal direction, it is assumed that the handset 1 is released from the hand. It is also possible to configure the reservation circuit to operate via a.

(Effect of the invention) .

As described in detail above, the present invention includes a hold circuit, a handset grip sensor that detects whether or not the handset is being held, and a handset grip sensor that switches the hold circuit to the hold mode in response to an output signal from the handset grip sensor when off-hook. In addition, by providing a mode switching circuit for canceling the hold mode, when placing a call on hold during a call, the telephone line is automatically placed on hold simply by removing the handset without pressing the hold button. This has the effect that there is no need to perform a hold operation.

Furthermore, since there is no need to go on-hook when the call is put on hold, it is expected that it will be easier to know that the call is on hold.
