Abstract

PURPOSE:To attain the use of the telephone set independently of the relative position with a user by designing a handset that it is connected optionally to both the right/left sides or the right or left side of a main body section where a dial pad is placed. CONSTITUTION:When a handset part 20L is connected to the left side of a telephone set main body section 10, a changeover switch 3 is switched to the position A, and a dial 1 and a trunk line /PBX selection button 2 or the like are used similarly as a normal key telephone set. In connecting the handset section 20R to the right side of the main body section 10, the changeover switch 3 is switched to the position B and similar operation is conducted. In connecting the handset to both sides, the switch 3 is changed over to the position B when the right side handset is used, and when the left side handset 20L responds to an incoming call, the changeover switch 3 is switched to the position A and the user responds to the call by depressing the trunk line /PBX selection button 2. The switch is used while being connected to the handset to be used independently of outgoing/incoming of the trunk line and an extension. Thus, the handsets at both the sides cannot be used at the same time in this way.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a button telephone, and more particularly, to a button telephone in which a handset can be connected to both the left and right sides, or to the left and right sides.

Traditionally, button telephones had a handset and receiver located on the left side, but when one button telephone was used by multiple people,
This has the disadvantage that it is difficult for people who are located on the right side of a button telephone to use the handset because it is far away, and it is difficult for people who listen with their right ear or left hand to use it.

SUMMARY OF THE INVENTION An object of the present invention is to provide a button telephone that solves the drawbacks that the handset is far away and difficult to use when using the telephone, and that people who listen with their right ear or who listen with their left hand find it difficult to use the telephone. be.

The button telephone of the present invention has a dial used for dial oscillation, function buttons such as speaker monitor, microphone on, and hold button, and a central office line/PBX selection button used for receiving and outgoing calls from the central office line/PBX line. A handset consisting of a main body having a telephone circuit network consisting of a communication path network, a handset selector switch used to select a plurality of handsets and a plurality of connectors for connecting the plurality of handsets, and a transmitter and a handset. and 2 that can be connected to the hook switch and main unit.
The present invention will now be described with reference to embodiments.

FIG. 1 is a system block diagram of one embodiment of the present invention. In Fig. 1, the phone main body] 0 is the dial pad l used when excavating the dial, the speaker monitor,
Function buttons such as microphone on and hold button, as well as the office line/PBX line used when receiving and sending calls from the office line/PBX line.
It has a button group 2 such as a PBX line selection button, a transmitting/receiving switch 3 used to select a plurality of handsets, and a plurality of connectors 4at4b for connecting with the handsets described later. In addition, although not shown in the drawings, a circuit network including various circuit components for configuring the telephone circuit is built inside the main body portion 10. A left handset part 20L is provided on the left side of the main body part 10, and a right handset part 20R is provided on the right side of the body part 10, and each connector 5a is provided with a right handset part 20R.
, 5b, and hook switches 6, 6 and handsets 7, 7 are provided.

In order to use the telephone of the present invention, when the handset section 20L is connected to the left side of the telephone main body section io, set the cut-off switch 3 to the A side, and dial like a normal button telephone. Use selection button 2, etc. Further, when the transmitter/receiver section 2OR is connected to the right side of the main body section 10, the changeover switch 3 is set to the B side and the same operation is performed. Furthermore, when the handset sections 20L and 20R are connected to both sides of the main body, when making a call using the right handset, the selector switch 3 is set to the B side to make a call. Also, when there is an incoming call next time and you want to answer it using the left handset 2OL, first move the selector switch 3 to the A side, press the central office line/PBX selection button 2, and answer the call.

As mentioned above, the button telephone of the present invention has the effect that the handset can be connected arbitrarily to either the left or right sides, the left side, or the right side of the main body where the dial pad etc. are located, and that it can be used conveniently regardless of its relative position to the user. be.
