Abstract

PURPOSE:To improve the call holding function by providing a function setting/ releasing the call holding state according to the condition present from the information including the information relating to the attitude of a handset detected by a handset attitude detecting means provided in the inside of the handset together with the state of a hook switch. CONSTITUTION:A handset attitude detection means 2 is located in the inside of the handset and is a meas to detect the attitude of the handset, that is, a difference of the height between a receiving speaker and a transmission microphone, and the information relating to the attitude is binarized based on the attitude that a caller grips the handset and keeps it in touch with the ear and the mouth to be in the OFF state and that the caller places the handset on a base close to a horizontal state to be in the ON state and sent to a talking state changeover means 1. A hook switch input 3 being a manual input changes over the setting/release of the call holding state and sends the information being ON/OFF binary information to the talking state changeover means 1. Thus, while the caller leaves the handset, the surrounding noise of the handset is shut off.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a telephone device, and more particularly to a telephone device having a call hold function.

[Conventional technology]

Conventionally, this type of telephone device has a mechanism that, when the caller leaves the handset during a normal call, manually operates a T-hook switch provided on the main body to set the call hold state and cut off the transmitted voice. The caller had to manually set and release the call on hold.

[Problem that the invention seeks to solve]

With the conventional telephone ath mentioned above, not only is it cumbersome to manually set and release a call on hold, but if you neglect to set a call on hold, the person on the other end of the line will hear the noise around the receiver. be.

[Means for solving problems]

The telephone device according to the present invention puts the telephone receiver into a call hold state according to preset conditions based on a receiver posture detecting means provided inside the telephone receiver, information regarding the posture of the telephone receiver obtained by the receiver posture detecting means, and the state of the 7-point switch. It must be equipped with all means for setting and canceling the settings.

〔Example〕

Next, the present invention will be explained with reference to all the drawings.

FIG. 1 is an overall configuration diagram of an embodiment of the present invention.

The handset attitude detection means 2 is a means for detecting the attitude of the handset, that is, the difference in height between the receiving speaker and the sending microphone. , the caller received the call 8!
The call state is converted into a binary value and the call state is switched by assuming that the posture when the receiver is held in iF' and touching the ear and mouth is the off state, and the posture when the caller is placing the handset on a table close to horizontal is the on state. It is sent to means 1. The hook switch 3 is used to manually set and release the 4-talk hold state, and also sends binary off/on information to the call state switching means 1. The call state switching means 1 includes a receiver attitude detection means 2 and a hook switch manual 3.
Regarding the two pieces of information, if either or both are on, the call hold state is set, and if both are off, the call hold state is released. This information about the call hold state or callable state is included in the call letter 111.
4 instruction output 4. From Figure 2 to Figure 5,
The operation of the receiver attitude detecting means 20 is shown, and three of them, FIGS. 2, 3, and 4, show the attitude when the receiver is placed on a nearly horizontal stand. When looking at the orientation of the receiving speaker and the transmitting microphone, they are facing downward in Figure 2, and sideways in Figure 3. 4
The difference between these three figures is that it is oriented upward in the figure. In the states shown in these three figures, it is assumed that the caller has completely interrupted the conversation and is away from the receiver. FIG. 5 shows the posture of the telephone receiver when the caller is having a conversation with the telephone receiver placed over the ear and mouth.

The states shown in FIGS. 2 to 4 are call hold states,
In order to distinguish the state shown in the fifth factor as a callable state, the following method is used.

When the center of the speaker for receiving calls is tR, and the center of the microphone for speaking is iT, the height difference between these two points is set as D.In the call hold state shown in Figures 2 to 4, D becomes a very small value. , D in the callable state shown in FIG.
is a sufficiently large value.

Therefore, by means of fully detecting this height difference L), it becomes possible to easily distinguish between these two states tqt. D
When the value of D gradually increases from O, and the value of D at the point where the call holding state switches to the call ready state is L, then L)<1. Information indicating that the call is on hold when D≧L, and that the call is available when D≧L is output as the call state instruction output 4.

〔Effect of the invention〕

As explained above, the present invention allows the caller to place the call on hold as appropriate by simply holding the receiver to the ear and mouth and having a conversation without being consciously aware of it, and then simply stopping the conversation and hanging up the receiver. It can be set and cleared using a conventional hook switch. As a result, while the caller takes off the handset, noise around the handset is blocked, preventing the other party from feeling uncomfortable, and when the caller picks up the handset again, the hook switch can be operated again to put the call on hold. The troublesomeness of releasing the state is φ.

[Brief explanation of the drawing]

Claims (1)

[Claims] In a telephone device that has a function of setting and canceling a call hold state based on the state of a hook switch provided on the main body of the telephone device, in addition to the state of the hook switch, the telephone receiver position detecting means provided inside the receiver is used. 1. A telephone device characterized by having a function of setting and canceling a call hold state according to preset conditions based on information including information regarding the posture of a receiver.
