Abstract

PURPOSE:To enable hand-free talking by rising a handset laid on a placing base automatically in response to an incoming call or a call signal from a telephone line, thereby facilitating the gripping of a handset at on-hook. CONSTITUTION:A liftup means 17 for a handset 12 and the handset 12 are supported in contact with a mechanical force transmission mechanism 16 and a power source 15 forwarded or reversed through the detection of a call and an incoming call signal detected at a line terminal to be rised or laid down. That is, the power source 15 is driven forward through the detection of an incoming call signal by the power source 15 to deliver a mechanical energy to the transmission mechanism 16 to raise a liftup means 17 supporting a handset 12 while being in contact therewith in the direction of solid line arrow at an open angle to part the handset 12 on a placing plate 11 from a handset receiving base 13 in interlocking with on/off of a hook switch thereby causing a talking enable on-hook state. Thus, the handset 12 is gripped rationally and when both hands are not available, hand-free talking is enabled.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone device useful when applied to a subscriber telephone with various functions or a cordless telephone capable of communicating with a plurality of handsets, which is used in homes such as ordinary households and offices. In response to the signal, the handset in the prone state (hereinafter referred to as the handset) is automatically raised to the off-hook state, and the handset can be picked up or the call can be made hands-free, and when the call ends, the original on-hook state is automatically established. It is configured to be able to return.

[0002]

2. Description of the Related Art In general, a telephone set includes an electronic circuit for making and receiving a telephone line, an electronic circuit such as a line selection switching function, a mechanism block, a power source, a wireless transceiver, and the like.
It consists of a dial button including a special button, an indicator light, a switch and a handset equipped with a wireless transmitter / receiver in some cases.Usually, the handset is placed in a prone position on the receiving part that interlocks with the hook switch on the stand, and the handset And the stand are connected by cord connection or cordless.

When an incoming (call) signal is received from the line,
When the operator activates the ringer and sounds, and recognizes that the call is received together with the lamp marking, the operator picks up the handset, and the line that was in the on-hook state is switched to the off-hook state, and the call state is set. By the way, when the handset is picked up from the stand, the stand is designed to have a recessed portion so that the fingers holding the handset do not get in the way and the whole handset is loosely embedded.

[0004]

2. Description of the Related Art As described above, when attempting to pick up the handset from the recessed portion of the stand when receiving a call, depending on the relative positional relationship between the operator and the telephone set, a finger may be placed along the longitudinal direction of the handset. For a shallow grip, keep your wrist inside
If you bend it to the outside and force it, or if you are in a hurry, you may slip and lose grip, or you may drop it and damage the handset.

DISCLOSURE OF THE INVENTION The present invention eliminates the above-mentioned obstacle at the time of picking up a handset in a telephone device in which a handset and a wireless telephone set the handset in a prone state on a stand, and receives the handset. It is in an off-hook state in synchronism with, and automatically stands up to facilitate grasping, and at the same time tries to make a call even in a hands-free state without using hands, the CPU detects the ringer on the telephone line and the CPU sets the handset. In addition to standing up, a command is sent to a holding circuit that determines the lower limit position, and a drive circuit that starts or stops by this signal and the output from the sensor, and a transmission mechanism to the lifting means that supports the power of this driving circuit to stand up the handset. It is connected to.

[0006]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of an electric / mechanical structure which is connected to L ₁ and L ₂ of a line terminal and is incorporated in a stand. 1 is a ringer detection circuit, 2 is a handset hook-on / off detection circuit, 10 is a CPU, and 3 is A holding circuit for holding the upper and lower limit positions of the handset upright and prone is shown in FIG.
2, a drive circuit including a power source 15 and a telephone / power circuit block 14, 5 is a drive mechanism including a transmission mechanism 16 and lifting means 17 in FIG. 2, and 6 is a sensor such as a limit switch. The CPU is a processing unit that can detect and judge information based on the ringer frequency, hook-on / off, timer, etc., and output a command, and also control signals for the transmission and reception stages of the wireless device (not shown).

Referring now to FIG. 2, in the embodiment shown in the figure, the power source 15 is rotated forward by the handset 12 detecting the incoming signal of the power source 15 on the table 11, and the power source 15 is rotated forward.
A mechanical means for transmitting mechanical energy to and lifting the handset 12 in contact with the handset 12 in the direction indicated by the solid line, the handset stands upright in the direction indicated by the dotted line, and the handset receiver is linked to the on / off state of the hook switch. 13 represents an off-hook state in which a call can be made apart from the telephone number 13.

The operation flow of the telephone device of the present invention will be described with reference to FIG. First, when a call is received from a telephone line, the handset lifting direction, that is, the motor is rotated forward by the input of a ringer tone signal for ringing the ringing system to reach the upper limit of the limit switch and the operation of the motor is stopped. At this point, the handset has already separated from the handset receiver on the stand and the hook switch is in the off-hook state, so that the call can be started.When the call ends, the handset is returned to the original on-hook state and the motor is reversed. When the handset is rotated, the lower limit of the limit switch is reached and the operation of the motor is stopped. Then, the handset is pushed into the handset receiver on the table and put in the on-hook state in the recess.

On the other hand, in order to put the telephone in the on-hook state into the call state, the hands-free button switch must be pushed in advance or the handset itself must be lifted to go off-hook. When it starts up and reaches the upper limit of the limit switch and stops rotating, a dial tone is sent and the call state is set.

The above is an example in which the handset is automatically lifted up based on the called signal from the telephone line. However, when the subscriber telephone is provided with a hands-free button switch and the signal is detected by pushing it in, the CPU thereafter It is also possible to have the mechanism of function to automatically raise the handset.

The cordless telephone is used as a charging stand.
Since the built-in battery is always maintained and the charging terminal is connected to the hooking circuit of the telephone line, the mobile unit is lifted and the telephone output is output by the transmitter of the mobile unit as usual. The line can be hooked off-hook directly, but it is also possible to automatically hook the mobile phone hands-free without removing it from the charging stand.

[0012]

As described above, according to the present invention, in response to an incoming or outgoing signal from the telephone line, the handset lying on the stand is automatically raised, so that the handset can be grasped without difficulty. It is possible to prevent damage due to lack of grip, and to confirm that the line is in a calling state other than visually recognizing incoming and outgoing calls with a lamp, etc., and as a design of the telephone device, the notch for inserting a finger can be eliminated to create a neat and beautiful appearance. Can be given.

In addition, since the handset can be automatically returned to the original on-hook position when the call is ended or the line is disconnected, it is possible to prevent the use of the line unnecessarily and to make a hands-free call to answer the incoming call when both hands are blocked. You can also
