Abstract

PURPOSE:To prevent the operation sensitivity of the telephone set from being effected by the operating condition by measuring a time till the operation is implemented after the access of a hand of the operator is sensed by a timer and using a sensitivity change means to adjust the sensitivity of a sensor depending on the difference between the measured data and an object. CONSTITUTION:A control means 1 uses a microcomputer to control a speech circuit or the like. A sensor 2 senses it that a hand of the operator is accessed and outputs a sensing signal. A sensitivity change means 3 sends an output of the sensor 2 to the control means 1 and revises the sensitivity of the sensor 2 by using a count data output from the control means 1. A timer 6 counts the time after the sensor 2 senses the access of the hand of the operator till the operation button 5 or a dial button 4 is depressed. Thus, the sensitivity of the sensor 2 is revised depending on the time counted by the timer 6.

Description

[Detailed description of the invention] Industrial applications The present invention relates to telephone devices.

Conventional technology In recent years, various functions have been added to telephone devices.When making a call with the handset on the receiver, instead of pressing the monitor button on the operation button, a sensor detects when a human hand approaches. However, in the conventional configuration described above, the sensitivity of the sensor is fixed. The disadvantage is that the operating feel varies greatly depending on the temperature.

The present invention solves the above-mentioned conventional problems, and aims to provide a telephone device in which the operational feeling of the device is not affected by usage conditions.

Means for Solving the Problems To achieve this object, the telephone device of the present invention is provided with a timer that measures the time from when the sensor detects the approach of the operator until the operation button or dial button is pressed. The sensor is equipped with a sensitivity changing means for automatically changing the sensitivity of the sensor based on the value υ measured by the timer.

Function: With this configuration, data is accumulated regarding individual differences in the operator's operating method, ease of detection by the sensor, etc., and the installation conditions of the device, and the sensitivity of the sensor is automatically adjusted based on the data. Therefore, you can always get a constant feeling of operation.

A sensor 2 detects that the operator's hand is brought close and outputs a detection signal. Reference numeral 3 denotes a sensitivity changing means, which sends the output of the sensor 2 to the control means 1 and changes the sensitivity of the sensor 2 based on the output of time measurement data from the control means 1. Reference numeral 4 denotes a dial button, which includes a push detection contact and an LED, and is connected to the control means 1. 6 is the operation button! There are a number of buttons, a speed dial registration button, amplification button, etc., and the output thereof is sent to the control means 1. Reference numeral 6 denotes a timer, which inputs start/stop signals from the control means 1 and outputs clock data or time-over information to the control means 1. Reference numeral 6a denotes a memory for storing timed values, which is built into the timer 6.

Reference numeral 7 denotes an automatic dial storage means, which automatically stores what is pressed on the dial button 6 via the control means 1. 8 is a hook switch, ON and O with control hand $1
He is in charge of FF. 9 is a receiver, which is made up of a receiver and a microphone. Reference numeral 1° is a telephone communication circuit, which functions to send a signal from the control means 1 to prevent the sound from the microphone of the receiver 9 from leaking to other lines, and to reduce the volume coming from the line to the receiver. . Reference numeral 11 denotes a dial transmission means, to which dial data is sent from the control means 1. Reference numeral 12 denotes line connection means, to which a signal is sent from the control means 1 to connect or disconnect multiple lines, and the lines are connected. A connection terminal 13 is used to connect the device to a line, and is connected to the line connection means 12.

Next, the operation of the above embodiment will be explained. First, the signal flow of the telephone device will be explained. FIG. 2 is a flowchart showing the operation of the control means 1. In FIG. 2, the control means 1 monitors the sensor input, the state of the hook switch 8, and the depression of the operation button 6 in the standby state (steps 14, 15 and 16). Here, when the sensor 2 detects that the operator's hand has come close and outputs it to the control means 1 via the sensitivity change means 3, the control means 1 controls the dial button 4.
The automatic dialing mode is displayed by lighting up the LED (step 17). A start output is sent to the timer 6 (step 18), and the automatic dialing mode enters the operation input waiting state. In the automatic dialing mode operation input waiting state, the control means 1 is the output of timer 6, pressing of dial button 4, and operation button 5.
is pressed and the state of the hook switch 8 is monitored (steps 19.21.22.23). Here, when the timer 6 outputs a timeout, the control means 1 cancels the automatic dial mode display of the dial button 4 (step 20),
The control means 1 returns to the standby state. When the dial button 4 is pressed while waiting for an automatic dial mode operation input, the control means 1 detects this and outputs a stop signal to the timer 6 (step 30), and cancels the automatic dial mode display of the dial button 4 (step 31). Furthermore, the control means 1
reads the timing data from timer 6 (step 32).
), and outputs this time measurement data to the sensitivity changing means 3 (step 33). Thereafter, the control means 1 drives the line connection means 12 to connect the line (step 34), and proceeds to automatic dialing processing.

In addition, when the operation button 6 is pressed down while there is no sensor input in the standby state, the control means 1 once outputs a start output to the timer 6 (step 36), and then performs the processing from step 26 onwards.

Next, the flow of signals in the sensitivity changing means 3 and the timer 6 will be explained. 3 is a flowchart of signals in the timer 6, and FIG. 4 is a flowchart of signals in the sensitivity changing means 3. In FIG. 3, the timer 6 is in the standby state and monitors the start output from the control means 1 (step 36).
, when a start signal is input, time measurement begins (step 3 completed).

The timer 6 monitors the elapsed time and the stop output of the control means 1 (steps 38 and 39).

When the elapsed time exceeds a predetermined value, the timer 6 outputs a time-over output (step 44), stops the il-time (step 45), and returns to the standby state. During timing,
When the control means 1 performs a stop output, the timer 6 stops timing (step 40), and stores the measured value and the memory 6a.
(step 41), and outputs the calculated value to the control means 1 as time data (step 42).

Furthermore, the timer 6 writes the measured value to the memory 6a (
Step 43), the standby state returns. In Figure 4,
The sensitivity changing means 3 always monitors the output of the control means 1 (step 46), reads the clock data when it is output from the control means 1 (step 47), and compares the read clock data, target value, and current value. From the set sensitivity, for example, calculate the sensitivity to be changed as follows: Setting sensitivity to be changed = Current set sensitivity x (Target value ÷ Time measurement data) 2 (Step 48), and change and set the sensitivity (Step 49).

As described above, according to this embodiment, by providing the sensitivity changing means 3 and the timer 6, the time from when the sensor detects the approach of the operator's hand until the operation is performed can be kept constant. I can do it. Furthermore, since the sensitivity is changed based on the average value obtained by measuring the time twice, it is possible to suppress changes in sensitivity more than necessary even in response to abnormal operations. Furthermore, in the above formula, by specifying the number of significant digits of the calculation result, the sensitivity setting value becomes a discrete value, and unnecessary sensitivity changes can be suppressed when the target value and timing data are close values. Since the square of the ratio between the target value and the clock data is reflected in the sensitivity setting, the amount of change can be increased when the difference is large, and the amount of change can be decreased when the difference is small.

Effects of the Invention As described above, the present invention measures the time from when the sensor detects the approach of the operator's hand until the operation is performed in actual use, and calculates the difference between the measured data and the target value. Accordingly, the sensitivity of the sensor is adjusted by the sensitivity changing means, and it has the effect that a constant operational feeling can be obtained regardless of the individual differences among operators and the installation conditions.

Furthermore, there is no need for adjustment to bring the sensor closer to the target value during manufacturing, which has the effect of reducing manufacturing costs.
