Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a display device for a telephone for managing call time, etc. of the telephone.

Conventionally, when using a telephone in an office, etc., for example, when a call is received and the call is forwarded to the person in charge, the person often places the call on hold and searches for the person in charge. Calls may be left on hold for long periods of time, resulting in
There were times when callers felt uncomfortable.

When the telephone receives a call or is in the outgoing state, the present invention shows whether the telephone is on hold or whether the call is from you or who is the other party. The above-mentioned problem is solved by letting those around you know whether the call is coming from someone else or not, and by allowing them to respond quickly if the call is received while the phone is on hold.

Furthermore, as a warning signal to the speaker during a call, a pre-programmed voice synthesis module is used to automatically generate the call time in sequence. At the same time, the call time zone may be displayed by lighting an LED lamp to visually encourage shortening the call time. In addition, the total call time can be memorized and automatically uttered as soon as the call ends, and if a printer is built in or connected, it can be printed out for each call time, allowing you to manage the cumulative call time depending on the purpose. , which is more convenient.

It is a well-known fact that voice current detection in telephones uses leakage of voice current in telephone pickups, etc., but using this method, the voice signal detection results are sent to the microcomputer control section, and this Based on the signals, each part display, vocalization, and print display are controlled.

An embodiment of the present invention will be described below with reference to the drawings.

Figure 1 is an external view of the device, Figure 2 is a block diagram,
FIG. 3 is a flowchart explaining the operation.

Examples of the functions of this device are as follows.

1 Color-coded lamp display for receiving and outgoing calls, and color-coded lamp display for local and long-distance calls.

2 LED lamp lights up and flashes for each call time zone.

3. Automatic voice announcement of call time (every 30 seconds or every minute).

4. Stores the total call time and automatically utters the voice when the call ends.

5 Automatic printing at the end of the call time (color-coded printing of call time and long-distance and local calls) using the built-in printer or external connection.

In FIGS. 1 and 2, reference numeral 1 denotes a telephone set mounted on the automatic call time management device 2. As shown in FIG. 3
is a voice current sensor (sensor means) consisting of a telephone pickup or the like, and the voice current detection result is sent to a microcomputer control section 4 (control means) built in the automatic call time management device 2. 5 is the power switch, 6 is the receiver, the color-coded display lamp for the transmission,
7 is a color-coded indicator lamp for inner city and outer city area (display means); 8
9 is a call time zone display lamp, 9 is a call time speaker, and 10 is a built-in printer.

In terms of circuitry, as shown in FIG.
1-dial pulse current detection circuit 12, local/long distance call color-specific driving circuit (discrimination means) 13, voice current generation check circuit 14, call time counting circuit 15, voice synthesis section 16, and voice generation circuit 17. It has a speech synthesis module 18, a printer control circuit 19, and the like.

The operation will be explained with reference to the flowchart in FIG.

First, the oscillation sound is checked, and if it is a continuous "poo" sound, the receiving and transmitting color lamps 6 are displayed.
The red LED light will light up to indicate an outgoing call. If the number of intermittent dial pulse current generation is less than 7 times, the local call indicator lamp 7 is turned on by color indicator lamp 7 for local and long distance calls, and if it is 7 or more times, a different color long distance call indicator is displayed. Turn on the lamp. When the generation of the dial pulse current stops, the call is confirmed by detecting whether a voice current is generated.

On the other hand, if it is an intermittent tone (ringing tone), the generation of the intermittent tone is confirmed, and the LED edge lamps of the receiving and outgoing color lamps 6 are turned on to indicate the received call. When the intermittent tone stops, the call is confirmed in the same manner as described above.

When the voice current is generated, the signal from the call sensor is held at H level, and the call timer (call time counter 15) starts counting. and,
The call time is accumulated and stored in memory, and the voice synthesizer 16 is operated every 30 seconds or every minute to automatically pronounce the call time at that time.

In addition, while the voice current is occurring intermittently, the call time may be within a predetermined period, for example, within 3 minutes, or between 3 minutes and 5 minutes.
minutes, divided into 5 minutes or more, and this period is detected.

In the call time zone display lamp 8, the LED edge lamp lights up if it is within 3 minutes, the LED red lamp lights up if it is 3 to 5 minutes, and the LED red lamp blinks if it is more than 5 minutes. do.

When the generation of the voice current stops, the signal of the call sensor returns to the L level, stops counting, outputs the total call time, and prints the accumulated call time on the printer 10. When printing, it is convenient to use different colors for local calls and long distance calls, which makes it easier to see and manage later.

As described above, the present invention includes a voice current sensor for detecting voice current of a telephone, and a signal received from the voice current sensor based on an outgoing call operation on the telephone or an incoming call to the telephone; a control means that determines whether the sound is continuous or intermittent, and determines that if it is a continuous sound, it is in a transmitting state; if it is an intermittent sound, it is in a receiving state; and based on the determination result of the control means. , and display means for identifying and displaying whether the telephone is in a calling state or a receiving state, so that people nearby can determine whether the telephone on hold is in a calling state or a receiving state. The reception display has the effect of allowing those around you to respond quickly.
