Abstract

PURPOSE:To dial assuredly by using a means which performs the collation between dialed telephone numbers and informing a wrong dial operation if carried out. CONSTITUTION:A changeover switch is set at the display side, and a card containing bar codes recorded is put into the main body of a telephone number display device. Then these bar codes are detected by an optical reader. A telephone number corresponding to the detected codes is displayed at a display part 1B, and the dial operation is performed with reference to the displayed numeric characters. If a mispush of the telephone number is detected through the collation, an information lamp AL is blinked by an information circuit 48. At the same time, the display contrast of an LED is inverted.

Description

[Detailed Description of the Invention] Technical Field of the Invention The present invention aims to eliminate erroneous dialing operations by comparing telephone number information recorded on a card or the like with the telephone number actually dialed. This invention relates to a telephone number display device.

BACKGROUND ART AND PROBLEMS Generally, when looking at a telephone number written on a business card or the like and trying to call that phone number, the following inconveniences may occur. In other words, the telephone number written on a business card is generally small and difficult to read, and when the recipient is an organization, corporation, etc., multiple telephone numbers, such as a representative number and a serial number, are written side by side. This is an inconvenience.

In such a case, first, the telephone number may be read and dialed incorrectly, resulting in an incorrect call. Second, even if you read the phone number correctly, when you read the phone number on the business card while dialing the phone, you may forget which part of the phone number you dialed, or you may be unable to read multiple phone numbers, for example. When these numbers are written side by side on a business card, the user's eyes tend to shift to a phone number on a line other than the line containing the desired phone number, and the user loses track of the next number to dial. As a result, the call may have to be repeated or the call may be the wrong one.

In order to solve this problem, the following methods have been proposed in the past.

The first method is to encode a telephone number, record the code on a card such as a business card by an appropriate means, read the code recorded on the card with an appropriate reader to generate an electrical signal, and generate an electrical signal. This is a method of sending a signal to the telephone line to call the other party. However, this method has the disadvantage that the telephone itself must be modified and construction work is required. Moreover, the equipment for carrying out this method is expensive.

The second method is to drive the rotary or push-button dial of the telephone from outside the telephone based on the electrical signal generated in the first method described above, without sending it to the telephone line. It is. however,
Although this method does not require modification of the telephone itself, it does require a dial drive mechanism to be attached to the telephone from the outside, and has the disadvantage that the mechanism becomes complex.

The third method is to connect a device in which a telephone number is stored in a storage device such as a semiconductor memory device or a memory device to a telephone, and when calling the other party stored in the storage device ξ, a device corresponding to the telephone number is connected to the telephone. This method involves pressing the button above. However, this method has disadvantages in that it is necessary to replace or modify the telephone, construction work is required, and the equipment is expensive. Furthermore, with this method, if the number of phone numbers that can be stored increases, it will not only be difficult to find the button on the device, but also the price of the entire device will be high, and it will be difficult to install the device. The disadvantage is that it requires a lot of space.

Purpose of the Invention The purpose of the present invention is to solve the above-mentioned problems and to provide a telephone number display device that verifies dialed telephone numbers and notifies the user of incorrect dialing. That is.

Structure of the Invention The telephone number display device according to the present invention includes a display means for displaying a telephone number to be dialed, a detection means for detecting the dialed number of the telephone, and a display means connected to the display means and the detection means to display the telephone number and the dialed number. and an erroneous operation display means for indicating the self-displayed number on the display means in response to the output of the collation means.

Embodiment of the Invention FIG. 1 shows a barcode list for displaying telephone numbers on a display. The illustrated barcode list may be arrayed over dozens of pages, such as in a telephone directory, or it may be pasted onto a plank as a single table. In addition, it is also possible to appropriately select and display on a CRT (cathode ray display tube). Which of these should be adopted may be determined depending on the amount of information to be stored, that is, the number of telephone numbers.

In Figure 1, the names of companies and organizations, names of individuals, etc. are recorded in the left column. In addition, the telephone number corresponding to the name written in the left column is recorded in the form of a barcode on the stone grout lR. This barcode is preferably printed on a separate piece of paper such as a card and pasted on it.

In other words, to print a barcode on the cart,
It is preferable to use the printing device 4 as described below.

2 and 3 show an example of a telephone number display device to which the present invention is applied. Here, Fig. 2 shows its external shape, and Fig. 3
The figure shows its internal configuration.

In Figure 2, BCR is /He code league,
By scanning the barcode shown in the right column R in the first figure, the number is displayed on the display section IB. Note that when using an eight-code league having a reading section having a shape that covers the entire barcode, it is not necessary to scan the barcode. 1 is a main body, and this main body 1 includes a stand IA on which a telephone (indicated by a broken line) is placed, a display part IB connected to the front end of this stand IA, and a display part IB. It has a key power part IC provided below, a cart insertion part IO provided between the display part IB and the key power part 1G, and a notification lamp A to notify that there is an error in the wheel operation.

Display section IB is read by barcode league BCR]T
This is for displaying the telephone number of 5×7.
It consists of a light emitting diode (LED) and its driving circuit. The size of the number displayed on this LED can be, for example, 15 mIIl x 15fflil. The key manual unit IC has ten numeric keys 2 corresponding to the numbers 0 to 9 and a clear key 3. Each numeric key 2 is connected to an eight-code generator (not shown) which generates a bar code signal corresponding to each digit when pressed.

The insertion section 10 has a horizontally long slit-shaped hole 4 having a width slightly larger than the width of a business card on which a barcode is to be printed, and guides 5 provided on both sides of the hole 4. Therefore, it is possible to insert the katido along the guide 5 only when it is inserted in a vertically long state.

Inside the main body 1, there is provided a thermal transfer mechanism for recording a barcode corresponding to a telephone number on a cart inserted into the main body 1 from the insertion part ID.

This thermal transfer mechanism records a barcode corresponding to a telephone number on the cart in the following manner. That is,
By sequentially pressing the number keys 2 on the keypad IC, the number 14,1 corresponding to the telephone number is read from the ROM (not shown) via the controller (not shown). The controller receives the barcode signal from 11 and displays the digits of the corresponding telephone number on the L of display section IB.
The barcode is displayed on the CD card and the thermal transfer mechanism is driven to record the read barcode on the card.

FIG. 3 shows an outline of the thermal transfer mechanism. As shown in FIG. 3, two sets of nip rollers 8 are arranged so as to grip the card 7 inserted into the main body 1 through the hole 4 of the insertion section ID.

Each set of nip rollers 8 is provided parallel to and horizontally with respect to each other. Each nip roller 8 also has a drive roller 8A coupled to a suitable motor (not shown) and a driven roller 8B brought into compressive contact with the drive roller 8A by suitable elastic means (not shown). Furthermore, the contact portion of two rollers in each set of nip rollers 8,
The height of each set of nip rollers 8 is determined in advance so that it is at the same height as the hole 4 of the insertion portion 10.

An insertion section 10 is located adjacent to both sides of the two sets of nip rollers 8.
Two microswitches 9 and 10 are provided to detect the front end of the card 7 inserted into the main body 1 through the hole 4. The motor driving the drive roller 8A and the two microswitches 9 and 1O are controlled by the controller described above.

When the card 7 is inserted into the main body 1 through the hole 4 of the insertion section 10, one of the microswitches 9 is closed, and the two drive rollers 8A of the two nip rollers 8 rotate in the directions indicated by arrows in FIG. do. Therefore, the card 7 inserted into the main body 1 through the hole 4 is pinched by one of the nip rollers 8 closer to the insertion section 10, and further fed into the main body 1 by the rotation of this one nip roller 8. The +iij end of the car 17 sent into the main body l in this way is
It is sandwiched between the externally applied nip rollers 8 and further fed into the main body 1 to close the other microswitch 10.

Thus, the driving of the two drive rollers 8A of the two nip rollers 8 is stopped, and the feeding of the cart 7 is stopped. In addition, between the two sets of 2 and Brote 8,
Guides (not shown) are provided on both sides of the cart so that the cart 7 fed during this period moves straight.

As shown in FIG. 3, a thermal head 11 for thermally transferring a barcode to the card 7 is provided between two sets of nip rollers 8 and close to the top surface of the cart 7 sandwiched between these rollers 8.

Similarly, a platen 12 is provided so as to be in contact with the lower surface of the card 7 and located directly below the thermal head 11.

Further, 13 is an ink film, which is rewound from a rewinding drum 14 provided in the main body 1, and is rewound to the thermal head 11.
and the top surface of the card 7, and the roll ■ solid drum 1
5 + Komakimi ν is done. Kite rollers 16 are provided on both sides of the thermal head 11 and allow the ink film 13 rewound from the unwinding tram 14 to run stably between the thermal head 11 and the upper surface of the card 7, and the ink film 13 is moved to the winding tram 15. Wind it up.

The thermal head II is lowered by a driving means (not shown) and presses the ink film 13 against the upper surface of the card 7 when recording a bar code on the upper surface of the card 7.

The thermal transfer mechanism is constructed as shown below, and furthermore,
As shown in FIG.
An optical reader 17 is placed close to the upper surface of the card 7 between the guide roller 16 that is closer to the sample roller 8.
Place. Here, it is necessary to arrange the optical reader 17 so that it is located on the same line as the thermal head 11 in the direction in which the card 7 is fed. The optical reader 17 is
It has a light emitter such as a laser beam and a light receiver, and the barcode recorded on the card 7 is irradiated with light from the light emitter, and the light reflected from the top of the card 7 is detected by the light receiver. 7
Detect the barcode above. This allows you to reconfirm already recorded barcodes or read new barcodes recorded on a separate card, thereby helping you to create the barcode list shown in Figure 1 without error. can.

As shown in Fig. 2, reference numeral 18 indicates a switch (
+ switch, which switches the previously mentioned controller (not shown) to "record" mode or "display" mode. This controller introduces ON signals from the two microswitches 9 and 10 and a barcode detection signal from the optical reader 17, and a motor (not shown) that drives the winding drum I5.
, a lifting means (not shown) for lifting and lowering the thermal whitening member 1, a motor (not shown) for driving the driving roller 8A of the nip roller 8, and an LCD of the display section IB are controlled.

It should be noted that the barcode reader BCR and the numerical data register NR can be easily configured using known techniques, so detailed explanations will be omitted.

With the above configuration, an 8-code corresponding to a telephone number is recorded on the card 7 in the following manner. Moreover, if necessary, the barcode recorded on the card 7 can be read again and the corresponding tE telephone number display section IB
It is also possible to display the That is, first, set the changeover switch 18 to the "record" side, and use the numeric keys 2 of the key operator IC to enter the telephone number (
number). As a result, a barcode signal corresponding to the telephone number is input to a controller (not shown), and at the same time, the entered telephone number is displayed on the LCD of the display section IB. Please note that if you enter the numbers incorrectly,
Press clear key 2 to erase the numbers displayed on the LCD by the controller and type in the phone number again. Then,
The card 7 is inserted into the main body l through the hole 4 of the insertion part 10.

As a result, the front end of the card 7 closes one of the microswitches 9, and the two nip rollers 8 rotate to feed the card 7 into the main body 1.

When the front end of the card 7 closes the other microswitch 10, the winding drum 15 starts winding up the ink film 13, and at the same time presses the ink film 13 against the thermal spatula (11) or the card 7 which is being fed. A bar code corresponding to the telephone number entered as described above is recorded on the card 7. When this recording is completed, the winding of the ink film 13 by the winding drum 15 is completed, and the two The rotation of the nip rollers 8 is temporarily stopped, and the thermal head 11 is rotated. Then, the two nip rollers 8 are reversed, and the card 7 fed into the main body 1 is rotated.
Return it to the outside of the main body. In this way, a barcode corresponding to the telephone number can be easily recorded on the card 7. Therefore, as shown in the first diagram, it is possible to paste the barcode recording paper close to each name field.

On the other hand, set the changeover switch 18 to the "display j side" and insert the card 7 on which the barcode is recorded as described above into the main body l through the hole 4 of the insertion part ID of the main body l. In the same manner as described above, the card 7 is fed into the main body l.During this feeding, the part where the barcode is recorded passes directly under the optical reader 17, and the barcode is read into the optical reader 17. The phone number corresponding to the 8-code that was shipped is displayed on display section I.
The card 7 is displayed on the CD by reversing the nip roller 8 at the end of detection.
put it back outside. In this way, from the card 7 on which the barcode is written, the numbers of the seven-part number corresponding to the barcode can be displayed on the LCD of the display section 1B having display numbers of an appropriate size.

The display section 1B is located immediately nη of the telephone placed on the stand [A], and the telephone number displayed there is very easy to see. Therefore, by scanning any desired barcode on the barcode list with the eight-code reader BCR, a telephone number of an appropriate size corresponding to that barcode is displayed on the display section IB, and the number is displayed. However, you can dial the phone extremely reliably.

In the above description, a recording means for recording a barcode on a card having an appropriate size, a reading means for reading the barcode recorded on the card,
Although a device has been shown in which a notifying means for notifying a telephone number corresponding to the read 8-code is integrated into the main body, the following modifications may be made.

(1) The recording means, the reading means, and the notification means are each configured independently.

(2) The recording means is an LCD that has a numeric keyboard and can display a corresponding barcode by inputting numbers manually using the numeric keys.
It may be constructed by combining a sheet-like barcode display having a barcode display (7) and a copying machine that can appropriately reduce the barcode on the LCD and record it on a card.

(3) In the case of (2) above, magnetic toner can be used as the material for recording the barcode on the card, and in this case, the reading means can be an optical one as described above. In addition to barcode readers, magnetic heads can also be used.

(4) As a notification means, not only a numeric display but also a voice notification device can be used. In this case, the telephone number is announced every digit or every arbitrary number of digits at appropriate time intervals. The notification can be made by voice.

Next, each embodiment for the notification lamp AL and the display section IB shown in the second figure will be described in detail.

FIGS. 4A and 4B show an embodiment in which two layers of transparent thin plates 40.42 are placed on a button switch of a button switch. An insulating material (for example, air) is mixed in so that the transparent thin plates 40 and 42 do not come into contact with each other. As shown by the broken line in FIG. 4A, the inner portions of the transparent thin plates 40 and 42 have a transparent conductive material v? Apply a film. Therefore, by pressing down on the upper surface of the thin plate 40, the two layers of electrodes come close to each other or come into contact with each other. In this way, the pressed telephone number is sequentially stored in the register 44, and is matched with the read number from the barcode reader BCR in the matching circuit 46. As a result of the 11θ match,
If the telephone number is entered incorrectly, the notification circuit 48
At the same time, the notification lamp AL (see Fig. 2) is made to blink and the display contrast of the LED is inverted. That is, the lighting state of the number corresponding to the incorrect dial operation and the surrounding area is reversed, thereby clearly indicating the number.

For example, if you are supposed to turn the dial "2" but turn any other number.

As shown in FIG. 4C, the contrast of the corresponding numbers is alternately inverted.

Figure 5 shows a pick-up coil 50 on the lead wire of a telephone device.
An example will be shown in which a dial pulse is detected. That is, the pulses sent out by turning the dial or pressing the button switch are detected by the pickup coil 5° and the pulse detection circuit 52, and the number of pulses is compared with the number read from the 8-code reader BCR. The verification circuit 54 performs this, and if there is an error, the notification circuit 56 causes the notification lamp AL (i2 (4 reference (μ)) to blink and at the same time inverts the display contrast of the corresponding LED.

FIG. 6 shows an embodiment in which a dialed number is detected by attaching a microphone MIG to the side of a telephone device equipped with a rotary dial. That is, in this embodiment, the dialed number is detected by detecting the length of the "g" sound that occurs when the dial is returned.

The sound detected by the mass microphone MIC is amplified by a buffer amplifier 80 and sent to a bandpass filter 61. This band pass filter 61 is set in advance to have a characteristic that allows only the return sound of the dial to pass through.

The dial tone signal that has passed through the band pass filter 61 is then introduced into a waveform shaping circuit 82, where it is transformed into a variable pulse waveform.

Then, the above-mentioned pulse signal is supplied as a gate opening/closing control signal for the counter 63 that introduces a predetermined clock signal CLK, and the count number is stored in the register 84.

Then, the verification circuit 85 determines the dial number based on the count accumulated in the register 64, and at the same time compares it with the number read from the barcode reader BCR. If there is an error, the notification circuit 66 causes the notification lamp AL (see FIG. 2) to blink and at the same time inverts the display contrast of the corresponding LED.

Figures 7 to 9 show the dial tone of the button
An embodiment is shown in which a dial number can be verified by detecting "P, B...". In the configuration shown in this figure, an extra base 70 and a speaker 74 are attached to the handset receiver compared to the configuration shown in FIG. 2.

Here, the speaker 74 has the same function as the notification lamp AL shown in the second diagram. The rest of the configuration is the same as that shown in the second diagram, so the parts that perform the same functions are included in the second diagram.
The same numbers as in the figure are given.

As shown in FIG. 8, a telephone handset 80 is mounted on the handset receiver holder 70 shown in FIG. 7. As shown in FIG. This cradle 70
has two recessed portions 82 and 84, and the transmitter portion 80A of the handset 80 has two recessed portions 82 and 84.
The handset receiver places the handset 80 on the base 70 so that the handset part 80B and the handset part 80B are fitted into each other. The two four parts 82, 84 are each provided with a microphone (not shown). Therefore, by placing the handset 80 on the base 70 and dialing the telephone, the microphone detects the dial operation sound (that is, the sound of the frequency corresponding to the pressing of the button switch).

As shown in FIG. 9, the handset receiver receives the dial operation sound detection signal from the microphone 80 provided on the stand 70.
It is input to one input terminal of the verification circuit 92. Verification circuit 82
- The above-mentioned barcode reader BC is connected to the other input terminal of the
A reference signal corresponding to the telephone number read from R is input, and these two manual numbers are compared to detect an error in dialing. The dial operation error detection signal sent from the collation circuit 92 is input to the drive circuit 84, and the drive circuit 94
As a result, a warning sound is generated from the speaker 74, and at the same time, the display contrast of the corresponding LED is inverted. The verification circuit 82 is reset by detecting an error in the dial operation or when there is no error in the dial operation as a result of comparing two bows made by two people. The speaker 74 can be attached to the power section 1G of the main body 1, for example, as shown in No. 1 in FIG.

In the above description, 5×7 dot LEDs are used in the display section IB to invert the contrast; however, the present invention can also be practiced with the following configuration, for example.

(1) In a 5×7 dot LED, only the displayed numbers are made to blink without inverting the display contrast.

(2) A liquid crystal display (Ic; D) is used instead of an LED.

(3) Instead of blinking the numeric display, a lamp placed above the corresponding digit is lit.

As described in detail, according to the present invention, it is possible to read a telephone number corresponding to an 8-code, reliably notify it, and reliably warn of an error in dialing based on the notification information. . Therefore, the filling machine can be dialed extremely reliably in ').
