Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cordless telephone composed of a master unit and one or a plurality of slave units connected to the master unit by radio transmission.

[0002]

2. Description of the Related Art With the widespread use of cordless telephones in homes and the like, there is an increasing demand for various additional functions in this type of telephone. For example, in recent cordless telephones, many have a built-in clock and are combined with an absence recording function so that the reception time is displayed so that the absence recording can be played back.

[0003]

Therefore, as a part of such multi-functionalization, the clock built in the master unit is used to set from the master unit or a slave unit installed at a place distant from the master unit. It is expected that if a ringing tone can be played at each time, the cordless telephone can also be used as an alarm clock, which is very convenient.

The present invention proposes a cordless telephone newly equipped with the above-mentioned wake-up function as an additional function.

[0005]

As a means for achieving the above object, the present invention comprises a master unit and one or more slave units connected to the master unit by wireless transmission, and at least a master unit. The machine is provided with a clock, time setting means and sounding means, and the slave is equipped with an operating section and a sounding means for setting the set time in the time setting means of the master, and when the clock time of the master exceeds the time set by the time setting means. It is provided with a wake-up control means for sending a calling signal to the handset or the base unit and causing the sounding means to emit a calling sound.

[0006]

In this cordless telephone, it is possible to set the desired set time (wake-up time) in the time setting means of the master unit by operating the operation unit of the slave unit. When the set time is set in the time setting means of the master unit, the wake-up control means provided in the master unit or the like compares the clock time with the set time of the time setting means, and the clock time passes the set time. Then, a calling signal is sent to the child device or the parent device (both may be used), and a ringing tone is emitted from the sounding means, and the alerting function is expressed by this ringing tone.

[0007]

EXAMPLES Examples of the present invention will be illustrated and described below.
1A and 1B show a block configuration of a cordless telephone according to the present invention separately for a master unit 1 and a slave unit 2.

The master unit 1 connected to the telephone line L has a control unit (CPU) 1A and a wireless transmission / reception unit 1B for wirelessly transmitting a signal between the slave unit 2 and the antenna 1C. As related to the wakeup function, at least a clock 1D, a time setting RAM (time setting means) 1E, a speaker (sound generation means) 1F, and a voice output unit 1G for outputting a message for wakeup are configured.

On the other hand, the slave unit 2 separated from the master unit 1 has a control unit (CPU) 2A and a wireless transmission / reception unit 2B for wirelessly transmitting a signal between the master unit 1 and an antenna 2C. , As a function related to the wake-up function, at least the time setting RAM1E of the base unit 1 is set to a more wirelessly set time (wake-up time), or the remote unit or the base unit that activates the wake-up function is designated and registered. Operation unit 2D for
And a speaker (sound producing means) 2E.

The control unit 1A mounted on the base unit 1
Serves as a wake-up control means for executing a predetermined wake-up function based on a program stored in advance in a ROM (not shown) or the like. That is, when the desired wake-up time is set in the time setting RAM 1E, the control unit 1A compares the clock time with the set time in the time setting RAM 1E, and when the clock time passes the set time, the control unit 1A and the wake-up time are set in advance. The speaker 2E or 1F is transmitted by sending a calling signal to any one of the designated child device 2 or the parent device 1 (or both).
The operation of ringing the ringing tone from is executed. Further, in addition to the ringing bell sound, the control section 1A also executes a message sending function of issuing a voice message to an operator who is an awakened person to wake up, in response to the ringing bell sound. There is.

FIG. 2 shows a flowchart of the wakeup control operation executed by the control unit 1A.

When an arbitrary set time is set in the time setting RAM 1E of the master unit 1, the control section 1A compares the clock time with the set time of the time setting RAM 1E (step s
1). When it is confirmed in step s1 that the clock time has passed the set time, the process proceeds to step s2, and the model to be called is discriminated based on the registration information of the called model that is designated together with the set time. Then, in the case of calling the slave 2, the series of operations in steps s3 to s7 is executed, and in the case of calling the master 1, the series of operations in steps s8 to s11 and s7 are executed.

That is, in the case of calling the slave unit, a call signal is sent from the control unit 1A of the master unit 1 to the control unit 2A of the slave unit 2 via wireless transmission between the wireless transmission / reception units 1B and 2B, and the slave unit Ring the ringing sound from the speaker 2E of the machine 2 (step s
3). The sending of the calling signal is continued until the awakened person operates the handset 2 off-hook in response to the bell sound (step s4). When the off-hook operation of the handset 2 is confirmed, the voice output unit 1G outputs the call signal. For example, a voice message such as "It's time to get up" is repeatedly transmitted and output from the speaker 2E of the handset 2 (step s5). As a result, it is possible to reliably notify the awakened person who responded while illusioning that it was a "phone call" to the effect that it was the wakeup time. Then, the output of the voice message is stopped (step s6) on condition that the operator who is an awakened person confirms the voice message and the on-hook operation is performed (step s6).
7) Then, the predetermined alarm control operation is ended.

Also in the case of calling the base unit, as in the above steps s3 to s7, the ringing of the ringing sound (step s8), the confirmation of the response at the base unit 1 (step s9), and the voice message up to the on-hook operation are performed. Is repeated (steps s10 and 11) and the audio output is stopped (step s7).

In the above-described wake-up function, not only the ringing bell sound that awakens the awakened person is sounded from the speakers 2E and 1F of the slave unit 2 or the master unit 1 at the set time, but also the slave unit in which the awakened person is sounded. 2 or a voice message for waking up is output on condition that the master unit 1 is off-hooked, so a more reliable waking up effect can be expected. In addition, it is possible to distinguish between the original telephone call and the wake-up call, which are problems when the telephone is also used as an alarm clock, and erroneously recognize the telephone call as the wake-up call without changing the ringing tone. The inconvenience of being unable to make a call does not occur.

3 and 4 show an example of the form of a cordless telephone to which the present invention is applied. That is, FIG. 3 shows a case where one or more cordless slave units 2 are wirelessly connected to the master unit 1 which is a main telephone in the form of a master-slave telephone, and FIG. The case where the device 2 is wirelessly connected in a one-to-one relationship is illustrated, and the present invention is applicable to any type of cordless telephone. Note that the same reference numerals as those given in the block diagram of FIG. 1 are given to corresponding portions in FIGS. 3 and 4.

[0017]

As described above, in the cordless telephone according to the present invention, when the desired wake-up time is set from the cordless slave unit to the time setting means provided in the master unit, the slave unit or the master unit is set at the set time. Since (or both) sounding means emits a ringing tone for wake-up, it is possible to realize a versatile multi-use having a high utility value that the cordless telephone can also be used as an wake-up clock.
