DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a calling device which informs a portable person of a call from, for example, a doorbell or a telephone by transmitting vibration.

[0002]

2. Description of the Related Art When a call needs to be made, such as when a call is received or when a doorbell is pressed, sound transmission is performed so that the telephone rings or an electronic sound is generated from a speaker. Calls are made normally. In many cases, the level of the generated sound can be adjusted. This may be due to differences in the distance between the person receiving the call and the device generating the ringing sound, differences in the level of hearing of the person receiving the call, or the level of noise at the place where the person receiving the call is located. This is because it is often convenient to make the ringing tone variable, for example.

[0003] If the person receiving the call is too far away to hear with a normal ringing tone, the call is transmitted by carrying a receiver, such as a pager or a cellular phone, to the person. You can also.
There is also a means for a visitor to talk using a receiver and a transmitter at two separate points, such as an intercom.

However, such a conventional apparatus has a problem that it is difficult to recognize a call when the called party is located in a loud place such as a machine operation. Therefore, visitors who press the doorbell need to enter dangerous places where machines are located or call out loudly because there is no response, and in the case of telephone, urgent matters or important communications are required. There was a problem that it was difficult to communicate.

Therefore, Japanese Patent Application Laid-Open No. Sho 62-154095 proposes that an information section for receiving information from a transmitter and stimulating a skin sensation based on the received output be provided in the receiver. This is typically a method of making a call by vibration, so that a call can be detected even in a place where the noise level is high. Another proposal for detecting a call by vibration is disclosed in Japanese Unexamined Patent Publication No.
No. 268854, JP-A-2-305125, JP-A-4-281629 and the like. In the preceding two publications, it is detected that a person wears this device, and only at that time, a call is made by vibration. In the last publication, the shaking of the telephone during the operation of the vibrator is increased.

Making a call by generating vibration is effective not only for a person in a place with a high noise level but also for a person with hearing impairment as disclosed in Japanese Patent Application Laid-Open No. 2-120946. It can also be used as a telephone device.

[0007]

However, in such a conventional calling device, only one type of calling associated in advance can be performed. Therefore, for example, when a call is made by vibrating a telephone, it is not possible to respond to a call bell, and vice versa. Further, in such a conventional apparatus, since the vibration frequency is determined uniformly, a person receiving a call may feel uncomfortable or difficult to perceive the vibration.

Accordingly, an object of the present invention is to provide a calling apparatus capable of individually recognizing and calling a plurality of objects to be notified even when a plurality of objects are to be notified.

Another object of the present invention is to provide a calling device which can set the frequency of the vibration associated with the object to an appropriate frequency when the calling is performed by vibration.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to embodiments.

FIG. 1 shows a system configuration of a calling device according to an embodiment of the present invention. This calling device is composed of a transmitter 15 connected to a telephone 11 and a doorbell 12 by cables 13 and 14, respectively, and a receiver 18 for receiving a radio wave 17 transmitted from an antenna 16 of the transmitter 15. . In the present embodiment, a band 19 similar to a watch band is attached to the receiver 18 so that it can be worn on the arm of the person who receives the call.

FIG. 2 shows a circuit configuration of the transmitter. The transmitter 15 has a CPU (central processing unit) 21 mounted thereon. The CPU 21 is connected to a ROM 23, a RAM 24, a receiving circuit 25, and a transmitting circuit 26 through a bus 22 such as a data bus. The ROM 23 is a read-only memory in which a procedure for transmission by the transmitter 15 is registered. The RAM 24 is a random access memory for temporarily storing data required for various control differences. The receiving circuit 25 receives an incoming signal transmitted from the cable 13 and a doorbell pressing signal transmitted from the cable 14. The transmission circuit 26 selectively generates a signal according to the reception of the reception circuit 25 from the signal generation circuit 28 and transmits the signal from the antenna 16.

FIG. 3 shows a control flow of the transmitter. The CPU 21 shown in FIG. 2 monitors the reception of the incoming signal or the doorbell pressing signal, and when receiving the incoming signal, determines that the telephone set 11 has been received (step S101; Y). Then, a first signal indicating that the telephone 11 has arrived is selected from the signal generation circuit 28 to the transmission circuit 26, and transmitted from the antenna 16 for a predetermined time (step S102).

On the other hand, when the doorbell signal is received, it is determined that the doorbell 12 has been pressed (step S10).
3; Y), a second signal indicating that the doorbell 12 has been pressed is selected from the signal generation circuit 28 to the transmission circuit 26, and transmitted from the antenna 16 for a predetermined time (step S104). When the incoming call of the telephone 11 and the pressing of the doorbell 12 are performed before and after in time, these signals are transmitted in that order.

FIG. 4 shows a main part of the circuit configuration of the receiver. The receiver 18 is also a CPU 3 for the control.
1 is provided. The CPU 31 is a bus 32 such as a data bus.
Are connected to a ROM 33, a RAM 34, a receiving circuit 35, an input circuit 36, a vibration control circuit 37, a frequency setting circuit 38, and a liquid crystal display circuit 39 via the.

The ROM 33 is a read-only memory in which procedures for various controls of the receiver 18 are stored. The RAM 34 is a random access memory for temporarily storing data necessary for control. The receiving circuit 35 is a circuit that receives a signal transmitted from the antenna 16 on the transmitting circuit 26 side via the antenna 41. The input circuit 36 inputs an operation signal from an operation switch 42 for changing the frequency and amplitude of the vibration. The vibration control circuit 37 is a drive circuit for causing the vibrator 43 to vibrate. The vibration is performed at the frequency set by the frequency setting circuit 38, and the amplitude can be changed. The liquid crystal display circuit 39 controls the display of the liquid crystal display 45.

FIG. 5 shows a state of control when the first or second signal is received by the receiver. The CPU 31 shown in FIG. 4 waits for a signal to be sent from the transmitter 15 (step S201).
When the signal is received (Y), it is determined whether or not it is the first signal indicating the incoming of the telephone 11 (step S202). If the signal is a first signal indicating the arrival of the telephone 11 (Y), the output of the frequency setting circuit 38 is set to the first frequency, and the vibration control circuit 37 is driven so that the vibrator 43 vibrates for a predetermined time t. Perform control (step S
203). At the same time, the liquid crystal display 45 displays that the telephone set 11 is in a receiving state (step S204).

On the other hand, if the second signal has been received (step S202; N), it means that the doorbell 12 has been pressed. Therefore, in this case, the output of the frequency setting circuit 38 is set to a second frequency different from the first frequency, and the drive control of the vibration control circuit 37 is performed so that the vibrator 43 vibrates for a predetermined time t (step S205).
At the same time, the doorbell 12 is displayed on the liquid crystal display 45.
Is displayed (step S204).

As described above, when the telephone 11 receives a call or the bell 12 is pressed, the receiver 18 vibrates at different frequencies. Therefore, the receiver carrying the receiver 18 on his / her wrist can easily determine whether the telephone 11 has arrived or the doorbell 12 has been pressed based on the vibration frequency. In addition, the receiver carrier can check the target of the call by looking at the liquid crystal display 45. Of course, the liquid crystal display 45 can be omitted from the receiver 18 depending on the device.

Although a specific procedure is not specifically described in this embodiment, the first frequency and the second frequency can be set to desired frequencies by operating the operation switch 42, respectively. The amplitude of the vibration can be set or changed to a desired value. If these frequencies and amplitude levels are stored in a non-volatile memory area configured by backing up a part of the RAM 34 with a battery, these current levels can be used even when the battery of the receiver 18 is replaced. Can be held without being erased.

In the above description, the case where the transmitter 15 and the receiver 18 each control the circuit operation by a program has been described. However, the same transmission control and reception control may be performed by a combination of pure circuits. Good.

Further, in the embodiment, the case of two types of calls, ie, a telephone and a bell, has been described. The type of the call can be determined. Further, in the embodiment, the receiver 18 is attached to the arm by the band 19,
It can be freely attached to other places such as the waist, and it is natural that the vibration frequency and amplitude should be slightly changed depending on each place.

Further, in the embodiment, the telephone 11 and the doorbell 12 are respectively connected to the transmitter 15 by wire, but the connection may be made wirelessly. In this case, it is not necessary to limit to radio waves, and other wireless means such as ultrasonic waves and light may be used.

[0032]

As described above, according to the first aspect of the present invention, the signal transmitted from the transmitter is determined on the receiver side in accordance with the type of signal to be broadcast, and the transmitted signal is determined. The vibration is generated in a vibration mode according to the type of the device, so that even if there are a plurality of objects to be notified, they can be identified and called. Therefore, calls can be made reliably even in loud noise places or people with hearing impairments, and callers may enter dangerous places due to lack of response, or delay response to emergency calls. The situation can be prevented.

According to the first aspect of the present invention, since vibration is generated in a vibration mode according to the type of the transmitted signal, the source of the vibration is different, for example, between right and left hands or between hands and feet. It may be attached to a place, and even if the frequency is the same, the place to vibrate is different, so that the destination of the response to the call may be determined. As a result, for example, the vibration occurs on the right hand side, so that it responds to the telephone placed in front of the right hand of the workplace, or the vibration occurs on the left foot, so that it responds to the intercom located on the left rear side. , It is possible to easily and reliably cope with three or more types of calls.

According to the second aspect of the present invention, since the calling of the telephone and the call bell can be processed in common by one transmitter and the receiver, an economical calling system can be constructed. Further, since it is possible to determine which call is being made, it is possible to prevent a useless action such that the person who receives the call goes in the wrong direction for handling. Further, since the call can be distinguished by the vibration, it is possible to reliably and promptly respond to a place with a lot of noise or a hearing-impaired person as described above.

According to the third aspect of the present invention, the portable receiver has the band attached to the arm, so that the difference in frequency can be sensed relatively sensitively, and the portable receiver has a lamp or a liquid crystal. When a display or the like is provided, there is an advantage that these display contents can be easily confirmed.

According to the fourth aspect of the present invention, since the transmitter is connected to the doorbell and the telephone by wire, the reliability of signal reception can be improved and the radio reception can be improved as compared with the case where signals are transmitted and received wirelessly to these devices. As a result, the circuit configuration of the transmitter can be simplified by omitting the receiving circuit.

Further, according to the fifth aspect of the present invention, a vibration state adjusting means capable of arbitrarily setting the frequency and amplitude of the vibration of the vibration means is provided. And amplitude can be selected,
For example, reception of an unpleasant frequency can be avoided. Further, by selecting a frequency, a plurality of call destinations can be easily recognized.

In the invention according to claim 6, since the receiver is provided with a display unit for visually displaying the response destination to the call, the confirmation of the response destination can be reliably performed in addition to the identification by the vibration. .
