Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a telephone in which all the functions of a telephone are housed in a handset.

(2) Prior Art and Problems In recent years, various telephones have been developed to improve the operability and functionality of telephone terminals. On the one hand, multi-functional telephones with multiple functions housed in the telephone have been developed, and along with the provision of a wide variety of services, some have also appeared that can also input data, etc. On the other hand, simple telephones have also been actively developed. In particular, compact integrated telephones have been proposed that have a handset with a telephone on/off function and a dialing function.

An on-hook call function has also been proposed for the handset type telephone, which allows calls to be made while the handset is placed on the stand. However, there are no proposals yet regarding its specific structure.

(3) Purpose of the Invention The object of the present invention is to provide a handset-type telephone that enables on-hook calls (calls made while the handset is placed).

(4) Structure of the Invention In order to achieve the above object, the present invention is a telephone in which a calling function etc. are housed in a handset, and the handset is equipped with a switch for forming a calling loop in addition to an on-box switch. The handset holder is provided with means for controlling on/off of the switch by moving a lever up and down, so that on-hook transmission can be made while the handset is placed on the holder.

(5) Examples of the invention The present invention will be explained in detail below using examples.

FIGS. 1 and 2 show an overview of the handset type telephone of the present invention, showing the handset in a state where it is stored in a stand and a state where the handset is raised, respectively. The handset 1 is provided with a dial button 11 on the back side, allowing dialing while the handset 1 is housed in the stand 2. Place the receiver on the top of handset 1,
A transmitting section 13 is formed at the lower part, and a hook switch 16 linked to the on/off hook circuit of the telephone is provided at a portion of the lower part that engages with the stand. This switch 16 is turned off by the weight of the handset 1 when it is stored in the stand 2, and turned on when it is lifted up.

Here, in the present invention, a lever 3 having a magnet in the center is attached to a stand so as to be movable up and down, and the handset 1 can be lifted up by operating the lever.
This makes it possible to send messages. As shown in Figure 2, by pushing up the lever 3, a magnet (described later) can be inserted into the inside of the stand where the handset is stored.
It is provided with a magnet operation hole 21 from which the magnet operates.
On the other hand, on the handset 1 side, a non-lock switch 15 is installed in addition to the hook switch 16 at a position corresponding to the magnet, and a metal plate 14 that is attracted to the magnet is stretched around the switch 15 ( (This metal plate may be attached to either the inside or the outside of the housing of the switch.) Details of this construction will become clear from FIG. 3, which is a sectional view taken along line A--A in FIG. 1. A magnet 31 is attached to the lever 3, which is movable up and down by springs 32 and 33, and is normally pulled more strongly downward. When this lever 3 is lifted upward with the handset 1 placed thereon (as shown in FIG. shall be.

This operation will be explained in more detail with reference to the cross-sectional views of FIG. 4A, FIG. 4B, and FIG. 4C.

FIG. 4A shows a state in which the handset is mounted, and normally, in this state, both the switch 15 and the touch switch 16 are in the off state.

When the handset is lifted to make a normal call, the hook switch 16 is turned on and a call can be made.

On the other hand, FIG. 4B shows a state in which a call is made with the handset mounted (on-hook call).

When making a call while the handset 1 is placed on the stand 2, push up the lever 3 so that the magnet 31 is attracted to the metal plate 14 and the switch 15
Push up to enter the transmitting state.

At this time, the switch 16 remains off. When the user dials the number of the other party and lifts up the handset 1 to talk to the other party, the switch 15 is released and the hook switch 16 is activated, keeping the telephone circuit in a loop state. Note that dial tones and the like during on-hook calls made while the handset is placed are heard through a built-in speaker (not shown).

FIG. 4C shows the handset in its lifted state. The transition from the state shown in FIG. 4A to the state shown in FIG. 4C is a normal transmission operation, but the transition from the state shown in FIG. 4B to FIG. 4C causes the magnet 31 and the metal plate 14 to separate, The switch 15 is turned off and the lever 3 is restored.

If the dial is in the state shown in FIG. 4B and you wish to stop making a call midway through, press down the lever 3 to return to the recovery state (FIG. 4A).

With the above configuration, switch 15 and hook switch 16
The relationship between the two is made clear by the main circuit diagram in FIG. In the figure, L1-L2 are connected to subscriber lines (connected to the exchange main body side), and the dial originating circuit, receiving circuit, transmitting circuit, etc. are on the right side of the figure.
It has been omitted. Switches SW1 and SW2 are the switches explained earlier (switches for on-box transmission)
The switches HS1 and HS2 operate in conjunction with the operation of the switch 16. B
is a bell circuit, and L is a hybrid coil.

Normally, the state shown in FIG. 4A is the state shown in FIG. 5, and when the state shown in FIG. ) is disconnected and forms a loop circuit for the line.

On the other hand, when a call is made as shown in Figure 4C, switches SW1 and SW2 are restored, and switch 16
As the circuit operates, a loop circuit is formed in the same way as before.

(6) Effects of the Invention According to the present invention, it is possible to provide a normal calling function and an on-hook calling mechanism with a simple configuration, thereby improving serviceability.
