Description

  The present invention relates to a cordless communication system and a second communication device of the cordless communication system.

For a cordless communication system that simultaneously outputs a ringing sound between a parent device and a child device when the parent device detects a ringing signal from a partner phone via a telephone line, for example, a cordless phone described in Patent Document 1 Are known. In this cordless telephone, when a call signal from the other party telephone is detected by the parent machine, the parent machine enters an incoming call confirmation operation for determining whether or not the call signal from the other party telephone is authentic. At the same time, a transmission set operation for performing a transmission / reception operation with the slave unit is started. When the incoming call confirmation operation confirms that the calling signal of the other party telephone is authentic, the master unit performs a ringing operation and transmits a connection request signal to the slave unit. When receiving the connection request signal, the slave unit starts a ringing operation. Therefore, when the incoming signal from the other party telephone is detected, it is possible to suppress the difference between the start time of the ringing operation of the base unit and the start time of the ringing operation of the handset as much as possible.

  When the handset 71 receives the ringing number information “3” transmitted from the MFP 10, the handset 71 sets the value of the ringing number information reception counter 54 a (ringing number information) to “3”, and the ringing timing is set. With reference to the ringing timing table of the table number “1” stored in the table memory 53a, the content of the ringing sound corresponding to the identification information “B” is acquired from the column where the ringing number information is “3”. At this time, since the content of the ringing sound is “one day”, the handset 71 outputs “one day” from the speaker 62.

  Next, when 2 seconds elapse after the value of the ringing number counter 13a (ringing number information) becomes “3”, the value of the ringing number counter 13a is updated to “4”. Then, the MFP 10 refers to the ringing timing table of the table number “1” stored in the ringing timing table memory 12a, and from the column where the ringing number information is “4”, the ringing sound corresponding to the identification information “S”. Get the contents. At this time, since the content of the ringing sound is “in the forest” which is the second measure of the song name “Kuma no Mori”, “in the forest” is output from the speaker 24.

  When the handset 51 receives the ringing number information “4” transmitted from the MFP 10, the handset 51 sets the value of the ringing number information reception counter 54 a (ringing number information) to “4”, and the ringing timing is set. With reference to the ringing timing table of the table number “1” stored in the table memory 53a, the content of the ringing sound corresponding to the identification information “A” is acquired from the column whose ringing number information is “4”. At this time, since the content of the ringing sound is “NULL”, the handset 51 does not output the ringing sound.

  When the handset 71 receives the ringing number information “4” transmitted from the MFP 10, the handset 71 sets the value of the ringing number information reception counter 54 a (ringing number information) to “4”, and the ringing timing is set. With reference to the ringing timing table of the table number “1” stored in the table memory 53a, the content of the ringing sound corresponding to the identification information “B” is acquired from the column where the ringing number information is “4”. At this time, since the content of the ringing sound is “NULL”, the handset 71 does not output the ringing sound.

  Based on the above-described operation, when the ringing number information is “5”, “in the forest” is output from the speaker 62 of the handset 51, and when the ringing number information is “6”, the handset “Forest” is output from the speaker 62 of 71. As a result, when the table number “1” is selected, the MFP 10, the slave unit 51, and the slave unit 71 ring the ringing sounds having the same contents in order, and the ringing sound is ringed to the user's ear. It will sound like

  The operation described above with reference to FIG. 2A will be described with reference to the timing chart of FIG. First, when the calling signal from the other party telephone is detected by the NCU 28 and the value of the ringing number counter 13a (ringing number information) becomes “1”, the MFP 10 starts to output “A” of “one day” from the speaker 24. When the output period is 2 seconds (when t1 is reached), the output of “hi” of “a certain day” is finished. As a result, the MFP 10 alone outputs a measure of “a certain day” in 2 seconds.

  Next, when 2 seconds have elapsed after the value of the ringing number counter 13a (ringing number information) becomes “1”, the ringing number counter 13a is updated to “2”. Then, the ringing frequency information reception counter 54a is also updated to “2”. Then, while the MFP 10 stops outputting the ringing sound, the slave unit 51 starts outputting “A” of “a certain day” from the speaker 62 (at t1), and when the output period becomes 2 seconds (t2). When it comes to time, finish outputting “hi” for “one day”. Thereby, the subunit | mobile_unit 51 outputs the measure of "a certain day" independently over 2 second.

  Then, when 2 seconds elapse after the value of the ringing number counter 13a (ringing number information) becomes “2”, the ringing number counter 13a is updated to “3”. Then, the ringing frequency information reception counter 54a is also updated to “3”. Then, the handset 51 stops outputting the ringing sound, while the handset 71 starts outputting “A” of “a certain day” from the speaker 62 (at t2), and the output period is 2 seconds. At the time of t3, output of “hi” of “a certain day” is finished. Thereby, the subunit | mobile_unit 71 outputs the measure of "a certain day" independently over 2 second.

  Next, when the value of the ringing number counter 13a (ringing number information) becomes “3” and 2 seconds have elapsed, the ringing number counter 13a is updated to “4”. Then, the ringing frequency information reception counter 54a is also updated to “4”. Then, the handset 71 stops outputting the ringing sound, while the MFP 10 starts to output “M” in “Forest” from the speaker 24 (at t3), and when the output period becomes 2 seconds ( At the time of t4), the output of “ka” in “in the forest” is finished. As a result, the MFP 10 alone outputs the measure “in the forest” in 2 seconds.

  Based on the above-described operation, when the ringing number information is “5”, “in the forest” is output from the speaker 62 of the handset 51, and when the ringing number information is “6”, the handset “Forest” is output from the speaker 62 of 71. Further, the sound output from the MFP 10, the slave unit 51, and the slave unit 71 is repeatedly performed until any of the MFP 10, the slave unit 51, and the slave unit 71 responds to a call from the other party telephone.

  As described above, when the ringing timing table having the table number “1” is selected from the ringing timing table memory 12a, the MFP 10 outputs the ringing sound in the order of MFP10 → slave unit 51 → slave unit 71 → MFP10. In addition, the output of each ringing sound can be controlled so that the ringing sound output from each speaker follows the same measure, that is, forms a ring. Therefore, even when the ringing sounds of the MFP 10, the handset 51, and the handset 71 are output all at once, the timing at which they actually sound does not overlap. The ringing sound that gives an unpleasant feeling can be turned into a ringing sound that gives the user a feeling of relaxation.

At this time, since the contents of the ringing sound corresponding to the identification information “S” and the identification information “B” in the column whose ringing number information is “2” are both “NULL”, the MFP 10 and the slave unit 71 No sound is output.

  On the other hand, when the handset 51 receives the ringing number information “2” transmitted from the MFP 10, the handset 51 sets the value (ringing number information) of the ringing number information reception counter 54 a to “2”, and the ringing timing is set. With reference to the ringing timing table of the table number “2” stored in the table memory 53a, the content of the ringing sound corresponding to the identification information “A” is acquired from the column where the ringing number information is “2”. At this time, since the content of the ringing sound is “in the forest”, the handset 51 outputs “in the forest”, which is the second measure of the song name “Kuma no Mori”, from the speaker 62.

  Next, when 2 seconds have elapsed after the value of the ringing number counter 13a (ringing number information) becomes “2”, the ringing number counter 13a is updated to “3”. Then, the ringing frequency information reception counter 54a is also updated to “3”. At this time, since the contents of the ringing sound corresponding to the identification information “S” and the identification information “A” in the column where the ringing number information is “3” are both “NULL”, the MFP 10 and the slave unit 51 No sound is output.

  On the other hand, when the handset 71 receives the ringing number information “3” transmitted from the MFP 10, the handset 71 sets the value (ringing number information) of the ringing number information reception counter 54 a to “3”, and the ringing timing is set. With reference to the ringing timing table of the table number “2” stored in the table memory 53a, the content of the ringing sound corresponding to the identification information “B” is acquired from the column where the ringing number information is “3”. At this time, since the contents of the ringing sound are “Kumasan ni”, which is the third measure of the song name “Mori no Kumasan”, “Kumasan ni” is output from the speaker 62.

  Next, when the value of the ringing number counter 13a (ringing number information) becomes “3” and 2 seconds have elapsed, the ringing number counter 13a is updated to “4”. Then, the ringing frequency information reception counter 54a is also updated to “4”. At this time, since the contents of the ringing sound corresponding to the identification information “A” and the identification information “B” in the row where the ringing number information is “4” are both “NULL”, the handset 51 and handset 71 Does not output a ringing tone.

  On the other hand, when the ringing number counter 13a is updated to “4”, the MFP 10 refers to the ringing timing table of the table number “2” stored in the ringing timing table memory 12a, and the ringing number information is “4”. The content of the ringing sound corresponding to the identification information “S” is acquired from the column. At this time, since the content of the ringing sound is “I met” that is the fourth measure of the song name “Kuma no Mori”, “I met” is output from the speaker 62.

  Next, when 2 seconds elapse after the value of the ringing number counter 13a (ringing number information) becomes “4”, the ringing number counter 13a is updated to “5”. Then, the ringing frequency information reception counter 54a is also updated to “5”. At this time, since the contents of the ringing sound corresponding to the identification information “S” and the identification information “B” in the row where the ringing number information is “5” are both “NULL”, the MFP 10 and the slave unit 71 No sound is output.

  On the other hand, when the handset 51 receives the ringing number information “5” transmitted from the MFP 10, the handset 51 sets the value (ringing number information) of the ringing number information reception counter 54 a to “5”, and the ringing timing is set. With reference to the ringing timing table of the table number “2” stored in the table memory 53a, the content of the ringing sound corresponding to the identification information “A” is acquired from the column where the ringing number information is “5”. At this time, since the content of the ringing sound is “one day”, the handset 51 outputs “one day”, which is the first measure of the song name “Kuma no Mori”, from the speaker 62.

  Then, when 2 seconds elapse after the value of the ringing number counter 13a (ringing number information) becomes “5”, the ringing number counter 13a is updated to “6”. Then, the ringing frequency information reception counter 54a is also updated to “6”. At this time, since the contents of the ringing sound corresponding to the identification information “S” and the identification information “A” in the row where the ringing number information is “6” are both “NULL”, the MFP 10 and the slave unit 51 No sound is output.

  On the other hand, when the handset 71 receives the ringing number information “6” transmitted from the MFP 10, the handset 71 sets the value (ringing number information) of the ringing number information reception counter 54 a to “6”, and the ringing timing is set. With reference to the ringing timing table of the table number “2” stored in the table memory 53a, the content of the ringing sound corresponding to the identification information “B” is acquired from the column where the ringing number information is “6”. At this time, since the content of the ringing sound is “in the forest” which is the second measure of the song name “Kuma no Mori”, “in the forest” is output from the speaker 62.

  The operation described above with reference to FIG. 3A will be described with reference to the timing chart of FIG. First, when the calling signal from the other party telephone is detected by the NCU 28 and the value of the ringing number counter 13a (ringing number information) becomes “1”, the MFP 10 starts to output “A” of “one day” from the speaker 24. When the output period is 2 seconds (when t1 is reached), the output of “hi” of “a certain day” is finished. As a result, the MFP 10 alone outputs a measure of “a certain day” in 2 seconds.

  Next, when 2 seconds have elapsed after the value of the ringing number counter 13a (ringing number information) becomes “1”, the ringing number counter 13a is updated to “2”. Then, the ringing frequency information reception counter 54a is also updated to “2”. Then, while the MFP 10 stops outputting the ringing sound, the handset 51 starts outputting “M” in “Forest” from the speaker 62 (at t1), and when the output period becomes 2 seconds ( At the time of t2), the output of “ka” in “in the forest” is finished. Thereby, the subunit | mobile_unit 51 outputs the measure of "in the forest" independently over 2 second.

  Then, when 2 seconds elapse after the value of the ringing number counter 13a (ringing number information) becomes “2”, the ringing number counter 13a is updated to “3”. Then, the ringing frequency information reception counter 54a is also updated to “3”. Then, the handset 51 stops outputting the ringing sound, while the handset 71 starts outputting “ku” of “Kumasan” from the speaker 62 (at t2), and the output period is 2 seconds. (When t3 time is reached), the output of “ni” of “to bear” is finished. Thereby, the subunit | mobile_unit 71 outputs the measure of "Kumasan ni" alone in 2 seconds.

  Next, when the value of the ringing number counter 13a (ringing number information) becomes “3” and 2 seconds have elapsed, the ringing number counter 13a is updated to “4”. Then, the ringing frequency information reception counter 54a is also updated to “4”. Then, the slave unit 71 stops outputting the ringing sound, while the MFP 10 starts outputting “de” of “I met” from the speaker 24 (at t3), and when the output period becomes 2 seconds (t4) When it comes to time, output “ta” for “I met”. As a result, the MFP 10 finishes outputting the “meeted” measure alone in 2 seconds.

  Based on the above-described operation, when the ringing number information is “5”, “a certain day” is output from the speaker 62 of the handset 51, and when the ringing number information is “6”, the handset 71. The speaker 62 outputs “in the forest”. Further, the sound output from the MFP 10, the slave unit 51, and the slave unit 71 is repeatedly performed until any of the MFP 10, the slave unit 51, and the slave unit 71 responds to a call from the other party telephone.

  As described above, when the ringing timing table with the table number “2” is selected from the ringing timing table memory 12a, the MFP 10 outputs the ringing sound in the order of MFP10 → slave unit 51 → slave unit 71 → MFP10. In addition, the output of each ringing sound can be controlled so that the song title “Mori no Kumasan” is formed as a series of performances by the ringing sound output from each speaker. Therefore, even when the ringing sounds of the MFP 10, the handset 51, and the handset 71 are output all at once, the timing at which they actually sound does not overlap. The ringing sound that gives an unpleasant feeling can be turned into a ringing sound that gives the user a feeling of relaxation.

  Finally, with reference to FIG. 4, the case where the ringing timing table of the table number “3” is selected by the user of the digital cordless telephone system 1 will be described. First, when the ringing timing table of the table number “3” is selected, identification information “S” is assigned to the MFP 10 and stored in the identification information memory 13c. Also, identification information “A” is assigned to the child device 51 and stored in the identification information memory 54 c of the child device 51. Further, identification information “B” is assigned to the child device 71 and stored in the identification information memory 54 c of the child device 71.

  When the calling signal from the other party telephone is detected by the NCU 28 and the value of the ringing number counter 13a (ringing number information) becomes “1”, the MFP 10 stores the table number “3” stored in the ringing timing table memory 12a. With reference to the ringing timing table, the content of the ringing sound corresponding to the identification information “S” is acquired from the column whose ringing number information is “1”. At this time, since the content of the ringing sound is “bell sound”, the MFP 10 outputs “bell sound” from the speaker 24.

  Further, when the handset 51 receives the ringing number information “1” transmitted from the MFP 10, the handset 51 sets the value (ringing number information) of the ringing number information reception counter 54 a to “1”, and the ringing timing is set. With reference to the ringing timing table of the table number “3” stored in the table memory 53a, the content of the ringing sound corresponding to the identification information “A” is acquired from the column whose ringing number information is “1”. At this time, since the content of the ringing sound is “one day” which is the first measure of the song name “Kuma no Mori”, “one day” is output from the speaker 62.

  When the value of the ringing number information reception counter 54a (ringing number information) is “1”, the content of the ringing sound corresponding to the identification information “B” in the column where the ringing number information is “1” is “NULL”. Therefore, the subunit | mobile_unit 71 does not output a ringing sound.

  Next, when 2 seconds have elapsed after the value of the ringing number counter 13a (ringing number information) becomes “1”, the ringing number counter 13a is updated to “2”. Then, the MFP 10 refers to the ringing timing table of the table number “3” stored in the ringing timing table memory 12a, and from the column where the ringing number information is “2”, the ringing sound corresponding to the identification information “S” is displayed. Get the contents. At this time, since the content of the ringing sound is “bell sound”, the MFP 10 outputs “bell sound” from the speaker 24.

  Further, when the handset 71 receives the ringing number information “2” transmitted from the MFP 10, the handset 71 sets the value (ringing number information) of the ringing number information reception counter 54 a to “2”, and the ringing timing is set. With reference to the ringing timing table of the table number “3” stored in the table memory 53a, the content of the ringing sound corresponding to the identification information “B” is acquired from the column where the ringing number information is “2”. At this time, since the content of the ringing sound is “one day” which is the first measure of the song name “Kuma no Mori”, “one day” is output from the speaker 62.

  When the value of the ringing number information reception counter 54a (ringing number information) is “2”, the content of the ringing sound corresponding to the identification information “A” in the column where the ringing number information is “2” is “NULL”. Therefore, the subunit | mobile_unit 51 does not output a ringing sound.

  Next, when 2 seconds have elapsed after the value of the ringing number counter 13a (ringing number information) becomes “2”, the ringing number counter 13a is updated to “3”. Then, the ringing frequency information reception counter 54a is also updated to “3”. At this time, since the contents of the ringing sound corresponding to the identification information “S”, the identification information “A”, and the identification information “B” in the column whose ringing number information is “3” are all “NULL”, None of the MFP 10, the slave unit 51, and the slave unit 71 outputs a ringing sound.

  Next, when the value of the ringing number counter 13a (ringing number information) becomes “3” and 2 seconds have elapsed, the ringing number counter 13a is updated to “4”. Then, the MFP 10 refers to the ringing timing table of the table number “3” stored in the ringing timing table memory 12 a, and from the column where the ringing number information is “4”, the ringing sound corresponding to the identification information “S”. Get the contents. At this time, since the content of the ringing sound is “bell sound”, the MFP 10 outputs “bell sound” from the speaker 24.

  Further, when the handset 51 receives the ringing number information “4” transmitted from the MFP 10, the handset 51 sets the value of the ringing number information reception counter 54 a (ringing number information) to “4”, and the ringing timing is set. With reference to the ringing timing table of the table number “3” stored in the table memory 53a, the content of the ringing sound corresponding to the identification information “A” is acquired from the column whose ringing number information is “4”. At this time, since the content of the ringing sound is “in the forest” which is the second measure of the song name “Kuma no Mori”, “in the forest” is output from the speaker 62.

  When the value of the ringing number information reception counter 54a (ringing number information) is “4”, the content of the ringing sound corresponding to the identification information “B” in the column where the ringing number information is “4” is “NULL”. Therefore, the subunit | mobile_unit 71 does not output a ringing sound.

  Next, when 2 seconds elapse after the value of the ringing number counter 13a (ringing number information) becomes “4”, the ringing number counter 13a is updated to “5”. Then, the MFP 10 refers to the ringing timing table of the table number “3” stored in the ringing timing table memory 12a, and from the column where the ringing number information is “5”, the ringing sound corresponding to the identification information “S”. Get the contents. At this time, since the content of the ringing sound is “bell sound”, the MFP 10 outputs “bell sound” from the speaker 24.

  Further, when the handset 71 receives the ringing number information “5” transmitted from the MFP 10, the handset 71 sets the value (ringing number information) of the ringing number information reception counter 54 a to “5” and sets the ringing timing. With reference to the ringing timing table of the table number “3” stored in the table memory 53a, the content of the ringing sound corresponding to the identification information “B” is acquired from the column where the ringing number information is “5”. At this time, since the content of the ringing sound is “in the forest” which is the second measure of the song name “Kuma no Mori”, “in the forest” is output from the speaker 62.

  When the value of the ringing number information reception counter 54a (ringing number information) is “5”, the content of the ringing sound corresponding to the identification information “A” in the column where the ringing number information is “5” is “NULL”. Therefore, the subunit | mobile_unit 51 does not output a ringing sound.

  Next, when the value of the ringing number counter 13a (ringing number information) becomes “5” and two seconds have elapsed, the ringing number counter 13a is updated to “6”. Then, the ringing frequency information reception counter 54a is also updated to “6”. At this time, since the contents of the ringing sound corresponding to the identification information “S”, the identification information “A”, and the identification information “B” in the column whose ringing number information is “6” are all “NULL”, None of the MFP 10, the slave unit 51, and the slave unit 71 outputs a ringing sound.

  The operation described above with reference to FIG. 4A will be described with reference to the timing chart of FIG. First, the ringing signal from the other party telephone is detected by the NCU 28, the value of the ringing number counter 13a (ringing number information) becomes “1”, and the ringing number information reception counter 54a also becomes “1”. Then, the MFP 10 starts outputting “bell sound” from the speaker 24. Further, the slave unit 51 starts to output “A” of “a certain day” from the speaker 62, and outputs “HI” of “a certain day” when the output period becomes 2 seconds (at t1). Finish. Thereby, the subunit | mobile_unit 51 outputs the measure of "a certain day" over 2 second.

  Next, when 2 seconds have elapsed after the value of the ringing number counter 13a (ringing number information) becomes “1”, the ringing number counter 13a is updated to “2”. Then, the ringing frequency information reception counter 54a is also updated to “2”. At this time, the MFP 10 continuously outputs the “bell sound” already output from the speaker 24 and outputs the “bell sound” until the output period reaches 2 seconds (until t2 o'clock). And the subunit | mobile_unit 51 stops outputting a ringing sound, On the other hand, the subunit | mobile_unit 71 starts outputting "A" of "a certain day" from the speaker 62 (at t1), and when an output period will be 2 second. At the time of t2, the output of “hi” of “a certain day” is finished. Thereby, the subunit | mobile_unit 71 outputs the bar of "a certain day" over 2 second.

  Next, when 2 seconds have elapsed after the value of the ringing number counter 13a (ringing number information) becomes “2”, the ringing number counter 13a is updated to “3”. Then, the ringing frequency information reception counter 54a is also updated to “3”. At this time, the MFP 10 and the slave unit 71 stop outputting the ringing sound (at time t2). The output stop is continued until the stop period reaches 2 seconds (until t3 time). In addition, the subunit | mobile_unit 51 also continues the stop of the output of a ringing sound.

  Next, when the value of the ringing number counter 13a (ringing number information) becomes “3” and 2 seconds have elapsed, the ringing number counter 13a is updated to “4”. Then, the ringing frequency information reception counter 54a is also updated to “4”. At this time, the MFP 10 starts outputting “bell sound” from the speaker 24. Further, the slave unit 51 starts to output “M” in “in the forest” from the speaker 62, and when the output period becomes 2 seconds (when t4 o'clock), “K” in “in the forest”. Finishes outputting. Thereby, the subunit | mobile_unit 51 outputs the measure of "in the forest" in 2 seconds. In addition, the subunit | mobile_unit 71 continues the stop of the output of a ringing sound.

  Next, when 2 seconds elapse after the value of the ringing number counter 13a (ringing number information) becomes “4”, the ringing number counter 13a is updated to “5”. Then, the ringing frequency information reception counter 54a is also updated to “5”. Also at this time, the MFP 10 continuously outputs the “bell sound” already output from the speaker 24, and outputs the “bell sound” until the output period reaches 2 seconds (until t5 o'clock). And the subunit | mobile_unit 51 stops the output of a ringing sound, On the other hand, the subunit | mobile_unit 71 starts outputting "mo" of "in the forest" from the speaker 62 (at t4), and an output period becomes 2 second. Sometimes (when t5 o'clock), the output of “ka” in “in the forest” is finished. Thereby, the subunit | mobile_unit 71 outputs the measure of "in the forest" in 2 seconds.

  Finally, when 2 seconds have elapsed after the value of the ringing number counter 13a (ringing number information) becomes “5”, the ringing number counter 13a is updated to “6”. Then, the ringing frequency information reception counter 54a is also updated to “6”. At this time, the MFP 10 and the slave unit 71 stop outputting the ringing sound (at time t5). Then, the output stop is continued until the stop period becomes 2 seconds (until t6 o'clock).

  As described above, when the ringing timing table with the table number “3” is selected from the ringing timing table memory 12a by the MFP 10, the MFP 10 continuously outputs the bell sound for 4 seconds, while the slave unit 51 and the slave unit 71 performs control in which the order of sound output is as follows: slave unit 51 → slave unit 71 → slave unit 51..., And the ring tone output from each speaker has the same measure for each measure. Each ringing sound output from each speaker 62 can be controlled so as to follow up, that is, form a ring. Therefore, after setting the ringing sound of the MFP 10 to a “bell sound” that is used relatively frequently, a ring can be formed by the ringing sounds of the handset 51 and handset 71. Accordingly, when the user of the digital cordless telephone system 1 cannot hear the bell sound of the MFP 10 but is in a place where both the ringing sound of the handset 51 and the ringing sound of the handset 71 can be heard, Thus, a relaxed feeling can be given without giving a sense of harshness due to the ringing sound of the handset 51 and handset 71.

  Next, a main process of the MFP 10 and a main process of the slave unit 51 that realize the operations described above with reference to FIGS. 2 to 4 will be described with reference to FIGS. First, a main process of the MFP 10 will be described with reference to FIG. FIG. 5 is a flowchart showing main processing of the MFP 10.

  This main process is a process that is repeatedly executed while the MFP 10 is powered on. In the main process, first, a ringing timing table selection process (S1) for selecting any one ringing timing table from the ringing timing tables of the table numbers “1” to “3” stored in the ringing timing table memory 12a is executed. The This ringing timing table can be selected, for example, when the user of the MFP 10 selects a ringing sound setting from a menu displayed on the LCD 16. In this embodiment, an example in which “Mr. Kuma no Mori” is selected as the ringing sound is shown (see FIGS. 2 to 4). In the digital cordless telephone system 1 of the present embodiment, in particular, in the MFP 10, the slave unit 51, and the slave unit 71, it is desired to output “Mr. Kuma no Mori” like a ring or as a series of performances. It is also possible to make it easy to select the output form of the ringing sound desired by the user by providing options such as “ring” and “performance” in the setting items of the menu.

  When one ringing timing table is selected in the process of S1, the table number stored in the selected ringing timing table is stored in the table number memory 14a and the MFP 10 stored in the selected ringing timing table. The identification information corresponding to is stored in the identification information memory 13c (S2). And the table number memorize | stored in the selected ringing timing table and the identification information corresponding to each subunit | mobile_unit are transmitted to the subunit | mobile_unit 51 and the subunit | mobile_unit 71 (S2).

  For example, when the ringing timing table shown in FIG. 2 is selected in the process of S1, the table number “1” is stored in the table number memory 14a and the identification information “S” is stored in the identification information in the process of S2. Store in the memory 13c. In step S2, the table number “1” and the identification information “A” are transmitted to the child device 51, and the table number “1” and the identification information “B” are transmitted to the child device 71. The identification information corresponding to the slave unit 51 and the slave unit 71 is transmitted from the MFP 10 to each slave unit at the same time in the process of S2, but the MFP 10 receives authentication information (each Since the IDs of the slave units are added to the identification information and transmitted, each slave unit does not receive the identification information of other slave units in error.

  Thereafter, the ringing number counter 13a is set to zero (S3), and the ringing timer 13b is reset (S4). Thereby, the initial setting after the start of the main process is completed. In the present embodiment, since the ringing number counter 13a is added at intervals of 2 seconds, “2 seconds” is set as a value when the ringing timer 13b is reset. After the process of S4, it is determined whether or not the call signal from the other party telephone is detected by the NCU 28 (S5). When the calling signal from the other party telephone is not detected (S5: No), the process of S5 is repeatedly executed. On the other hand, when the calling signal from the other party telephone is detected (S5: Yes), the value of the ringing number counter 13a is incremented by 1 (S6), and the value of the ringing number counter 13a is used as the ringing number information together with the ringing signal. It transmits to the subunit | mobile_unit 51 and the subunit | mobile_unit 71 (S7).

  Then, based on the selected ringing timing table (based on the ringing timing table corresponding to the table number stored in the table number memory 14a), the ringing sound is output from the speaker 24 (S8). In the process of S8, for example, when the ringing timing table of the table number “1” shown in FIG. 2A is selected and the value of the ringing number counter 13a (ringing number information) is “1”, FIG. As shown in (b), the MFP 10 starts outputting “A” of “a certain day” from the speaker 24.

  Thereafter, the value of the ringing timer 13b is subtracted based on the elapsed time from the detection of the calling signal (or the elapsed time after the processing of S7) (S9), and responds to the calling signal from the other party telephone. It is determined whether or not a response signal indicating this is detected by pressing the operation key 15 or the like (S10). When a response signal is not detected (S10: No), it is determined whether a response signal is received from the child device 51 or the child device 71 (S11). If no response signal is received from either the slave unit 51 or the slave unit 71 (S11: No), whether or not the value of the ring timer 13b is zero, that is, the value of the ring number counter 13a is updated. (S12) It is determined whether or not 2 seconds have passed since the ringing frequency information was updated (S12). If the value of the ringing timer 13b is not zero (S12: No), since the value of the ringing number counter 13a has been updated (after the ringing number information has been updated), two seconds have not yet elapsed. ˜S12 is repeatedly executed. As described above, if the value of the ringing number counter 13a is updated (after the ringing number information is updated), if 2 seconds have not yet elapsed, the process of S8 is repeatedly executed. For example, the process of S1 2A, when the ringing timing table of the table number “1” shown in FIG. 2A is selected, as shown in FIG. 2B, the MFP 10 from the speaker 24 to “Hi” of “a certain day”. Can be output continuously.

  On the other hand, when the value of the ringing timer 13b is zero (S12: Yes), 2 seconds have elapsed since the value of the ringing number counter 13a was updated (after the ringing number information was updated). The ringing timer 13b is reset (S20), the process returns to S6, and the value of the ringing number counter 13a is incremented by 1 (S6). Then, in the process of S7, the value of the ringing number counter 13a added by 1 is transmitted as ringing number information to the handset 51 and handset 71 together with the ringing signal, and then the process of S8 is executed. In the process of S8 after 1 is added to the ringing number counter 13a, for example, the ringing timing table of the table number “1” shown in FIG. 2A is selected, and the value of the ringing number counter 13a (ringing number information) ) Is “2”, as shown in FIG. 2B, the MFP 10 stops outputting the ringing sound from the speaker 24.

  As described above, the MFP 10 can intermittently output a ringing sound from the speaker 24 by using the ringing number counter 13a, the ringing timer 13b, and the table number memory 14a (one selected ringing timing table).

  When a response signal is detected by pressing the operation key 15 or the like in the process of S10 (S10: Yes), a response signal indicating that the call from the other party telephone is answered is transmitted to the slave unit 51 and the slave unit 71. (S13). Thereafter, the output of the ringing sound output from the speaker 24 is stopped (S14), and a known call process for making a call with the other party telephone is executed (S15).

  Thereafter, it is determined whether or not the call has ended (S16). If the call with the other party telephone has not ended yet (S16: No), the process of S15 is repeatedly executed. On the other hand, when the call with the other party telephone is finished (S16: Yes), an end signal indicating that the call with the other party telephone is finished is transmitted to the handset 51 and handset 71 (S17). The process ends.

  If a response signal is received from either the slave unit 51 or the slave unit 71 in the process of S11 (S11: Yes), the output of the ringing sound output from the speaker 24 is stopped (S18). Then, it is determined whether or not an end signal indicating that the call with the other party telephone has ended is received from the handset 51 or handset 71 with which the call is being made (S19). If the end signal has not been received (S19: No), the process of S19 is repeated. On the other hand, when the end signal is received (S19: Yes), this main process is ended.

  Next, with reference to FIG. 6, the main process of the subunit | mobile_unit 51 is demonstrated. FIG. 6 is a flowchart showing the main process of the slave unit 51. Since the main process of the slave unit 71 is the same as the main process of the slave unit 51, the description thereof is omitted.

  This main process is a process that is repeatedly executed while the slave unit 51 is powered on. In the main process, first, it is determined whether or not the table number and identification information transmitted from the MFP 10 have been received (S51). When the table number and the identification information are not received (S51: No), the process of S51 is repeatedly executed. On the other hand, when the table number and the identification information are received (S51: Yes), the received table number is stored in the table number memory 55a, and the received identification information is stored in the identification information memory 54c (S52).

  Thereafter, the ringing frequency information reception counter 54a is set to zero (S53), and the ringing timer 54b is reset (S54). Thereby, the initial setting after the start of the main process is completed. In the present embodiment, since the ringing frequency information reception counter 54a is added at intervals of 2 seconds, “2 seconds” is set as a value when the ringing timer 54b is reset. After the processing of S54, it is determined whether or not the ringing signal and ringing number information have been received (S55). When the ringing signal and ringing number information have not been received (S55: No), the process of S55 is repeatedly executed. On the other hand, when the ringing signal and ringing number information are received (S55: Yes), the value of the ringing number information reception counter 54a is set to the value indicated by the received ringing number information (S56).

  Thus, in the process of S56, since the value of the ringing number information reception counter 54a is set to the value indicated by the received ringing number information, even when the handset 51 fails to receive the ringing number information and the ringing signal. By receiving the ringing number information and the ringing signal transmitted from the MFP 10 after 2 seconds, the value of the ringing number information reception counter 54a of the slave unit 51 can be matched with the value of the ringing number counter 13a of the MFP 10.

  After the process of S56, based on the selected ringing timing table (based on the ringing timing table corresponding to the table number stored in the table number memory 55a), the ringing sound is output from the speaker 62 (S57). In the process of S57, for example, when the table number stored in the table number memory 55a is “1” and the value of the ringing number information reception counter 54a (ringing number information) is “1”, it is shown in FIG. As a result, the handset 51 stops outputting the ringing sound. Further, for example, when the table number stored in the table number memory 55a is “1” and the value of the ringing number information reception counter 54a (ringing number information) is “2”, as shown in FIG. 51 starts to output “a” of “a certain day” from the speaker 62.

  Thereafter, the ring timer 54b is subtracted (S58). Here, the value of the ringing timer 54b is subtracted based on the elapsed time since the ringing signal was received in the process of S55. Subsequently, it is determined whether or not a response signal responding to the call from the other party telephone is detected by pressing the operation key 56 or the like (S59). If a response signal is not detected (S59: No), it is determined whether a response signal is received from the MFP 10 or the slave unit 71 (S60). If no response signal has been received from either the MFP 10 or the slave unit 71 (S60: No), whether or not the value of the ring timer 54b is zero, that is, the value of the ring number information reception counter 54a is updated. It is determined whether or not 2 seconds have elapsed since the ringing frequency information was updated (S61). If the value of the ring timer 54b is not zero (S61: No), since the value of the ring number reception counter 54a has been updated (after the ring number information has been updated), 2 seconds have not yet elapsed. , S57 to S61 are repeatedly executed. As described above, if the value of the ringing number information reception counter 54a is updated (after the ringing number information is updated), if 2 seconds have not yet elapsed, the process of S57 is repeatedly executed. When the table number stored in the number memory 55a is “1” and the value of the ringing number information reception counter 54a (ringing number information) is “2”, as shown in FIG. To “hi” of “one day” can be output continuously.

  On the other hand, when the value of the ringing timer 54b is zero (S61: Yes), 2 seconds have elapsed since the value of the ringing number information reception counter 54a is updated (after the ringing number information is updated). Therefore, after returning to the processing of S54 and resetting the ringing timer 54b, it is determined again whether or not the ringing signal and ringing number information have been received (S55). When the ringing signal and ringing number information are received again (S55: Yes), the value of the ringing number information reception counter 54a is updated (S56), and the process of S57 is executed again. In the process of S57 after the value of the ringing number information reception counter 54a is updated, for example, the table number stored in the table number memory 55a in the process of S52 is “1”, and the ringing number information reception counter 54a When the value (ringing frequency information) is “3”, as shown in FIG. 2, the handset 51 stops outputting the ringing sound from the speaker 62.

  As described above, by using the ringing number information reception counter 54a, the ringing timer 54b, and the table number memory 55a (one selected ringing timing table), the slave unit 51 can intermittently output the ringing sound from the speaker 62. Can do.

  In the process of S59, when a response signal is detected by pressing the operation key 56 or the like (S59: Yes), a response signal indicating that the call from the other party telephone is answered is transmitted to the MFP 10 and the slave unit 71 ( S62). Thereafter, the output of the ringing sound output from the speaker 62 is stopped (S63), and a known call process for making a call with the other party telephone is executed (S64).

  Thereafter, it is determined whether or not the call has ended (S65). If the call with the other party telephone has not ended yet (S65: No), the process of S64 is repeatedly executed. On the other hand, when the call with the other party telephone is finished (S65: Yes), an end signal indicating that the call with the other party telephone is finished is transmitted to the MFP 10 and the slave unit 71 (S66). finish.

  If a response signal is received from either the MFP 10 or the slave unit 71 in the process of S60 (S60: Yes), the output of the ringing sound output from the speaker 62 is stopped (S67). Then, it is determined whether or not an end signal indicating that the call with the other party telephone is ended is received from the MFP 10 or the handset 71 on which the call is made (S68). If the end signal has not been received (S68: No), the process of S68 is repeated. On the other hand, when the end signal is received (S68: Yes), this main process is ended.

  As described above, according to the digital cordless telephone system 1 in the present embodiment, when the ring timing table having the table number “1” or the table number “2” is selected from the ring timing table memory 12a, the MFP 10, the slave unit 51, and The ringing sound output from the handset 71 can be set to a single sound without overlapping. Therefore, even if the user of the digital cordless telephone system 1 is in a position where not only the ringing sound of the MFP 10 but also the ringing sounds of the handset 51 and handset 71 can be heard, a synthesized sound by each ringing sound is formed. Therefore, it is possible to output a ringing sound without giving a harsh feeling to the user.

  Further, according to the digital cordless telephone system 1 in the present embodiment, the ringing sound output from the handset 51 and handset 71 is superimposed regardless of which of the ringing timing tables stored in the ringing timing table memory 12a is selected. Can be set to a single sound without any problems. Therefore, even if the handset 51 or handset 71 is not placed in a place where it should originally be installed, the user of the digital cordless telephone system 1 can rely on a single ringing sound output from each handset. , It is possible to specify the location where each slave unit is currently located.

  Next, the digital cordless telephone system 100 according to the second embodiment will be described with reference to FIGS. First, an electrical configuration of the digital cordless telephone system 100 will be described with reference to FIG. FIG. 7 is a block diagram showing an electrical configuration of digital cordless telephone system 100 including MFP 110 and slave unit 151 (slave unit 171). In the digital cordless telephone system 100 according to the second embodiment, when the MFP 110 detects a ringing signal from the other party telephone, the MFP 110 controls the output or stop of the ringing sound by the MFP 110 and the slave unit 151 (slave unit) 171) is transmitted to switch the output or stop of the ringing sound, and the output or stop of the ringing sound by the slave unit 151 (slave unit 171) is controlled. Therefore, according to the digital cordless telephone system 100 in the second embodiment, the MFP 110 can control the output or stop of the ringing sound by the slave unit 151 (slave unit 171) in addition to the output or stop of the ringing sound by the MFP 110. it can. Accordingly, the output or stop of the ringing sound by the MFP 110 and the output or stop of the ringing sound by the slave unit 151 (slave unit 171) are asynchronous (the output or stop of the ringing sound by the MFP 110 and the slave unit 151 (slave unit) It is possible to prevent the output or stop of the ringing sound by the machine 171) from deviating with time).

  In the electrical configuration of the digital cordless telephone system 100 according to the second embodiment, the contents of the RAM 13 in the MFP 10 used in the digital cordless telephone system 1 according to the first embodiment and the slave unit 51 (slave unit 71). Since the contents of the ROM 53 and the RAM 54 are partially changed, the same parts as those of the digital cordless telephone system 1 in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted and the changed points are described. I do. In addition, the switching signal transmitted from the MFP 110 to each child device in the second embodiment corresponds to a ringing signal transmitted from the MFP 10 to each child device in the first embodiment.

  First, the electrical configuration of the MFP 110 will be described. In the MFP 110, an identification information detection memory 13d is newly provided in the RAM 13 as compared with the MFP 10 of the first embodiment. The identification information detection memory 13d is a memory that stores identification information indicating whether the device that controls the output of the ringing sound is the MFP 110, the slave unit 151, or the slave unit 171. When the identification information is stored in the identification information detection memory 13d, the MFP 110 controls the device corresponding to the stored identification information (MFP 110, the slave unit 151, or the slave unit 171) to output a ringing sound. It is determined that it is a target.

  Next, the slave unit 151 will be described. In addition, since the subunit | mobile_unit 171 is the structure same as the subunit | mobile_unit 151, description about an electrical structure is abbreviate | omitted.

  The subunit | mobile_unit 151 deletes the ringing timing table memory 53a provided in ROM53 with respect to the subunit | mobile_unit 51 of 1st Embodiment, and has newly provided the sound information memory 53b. The sound information memory 53b is a memory that stores information on ringing sounds (contents of ringing sounds) output from the speakers 62. Unlike the ringing timing table (see FIGS. 2 to 4) stored in the ringing timing table memory 53a, the sound information memory 53b is not associated with ringing number information and identification information, but only the contents of the ringing sound. Is stored (the ringing number information and the identification information are not stored).

  Moreover, the subunit | mobile_unit 151 deletes the ringing frequency information reception counter 54a and the ringing timer 54b provided in RAM54 with respect to the subunit | mobile_unit 51 of 1st Embodiment, and provides the sound output flag 54d newly. The sound output flag 54d is a flag for controlling the output and stop of the ringing sound from the speaker 62. When the sound output flag 54d is turned on, a ringing sound is output from the speaker 62 during the on-period. On the other hand, when the sound output flag 54d is turned off, the output of the ringing sound is stopped. The sound output flag 54d is switched on / off every time a switching signal transmitted from the MFP 110 is received.

  Next, a ringing timing table stored in the ringing timing table memory 12a of the MFP 110 will be described with reference to FIG. FIG. 8A is a diagram schematically showing the ringing timing table for table number “4”, and FIG. 8B is the MFP 110 executed based on the ringing timing table for table number “4”. 5 is a timing chart showing the output timing of each ringing sound of the slave unit 151 and the slave unit 171.

  As shown in FIG. 8A, the ringing timing table of the table number “4” stored in the ringing timing table memory 12a includes ringing number information, identification information, and the contents of ringing sounds.

  When the ring timing table of the table number “4” is selected by the user of the digital cordless telephone system 100, the identification information “S” is assigned to the MFP 110, and this is stored in the identification information memory 13c. Further, identification information “A” is assigned to the slave unit 151 and stored in the identification information memory 54 c of the slave unit 151. Furthermore, identification information “B” is assigned to the child device 171 and stored in the identification information memory 54 c of the child device 171.

  When the calling signal from the other party telephone is detected by the NCU 28 and the value of the ringing number counter 13a (ringing number information) becomes “1”, the MFP 110 stores the table number “4” stored in the ringing timing table memory 12a. With reference to the ringing timing table, the content of the ringing sound, that is, the identification information in which the bell sound is stored is detected from the column where the ringing number information is “1”, and the detected identification information is stored in the identification information detection memory 13d. Remember. At this time, since the identification information in which the bell sound is stored is “S”, the MFP 10 stores the identification information “S” in the identification information detection memory 13d. Then, since the identification information stored in the identification information detection memory 13d is “S”, the MFP 10 determines that the control target for outputting the ringing sound is its own device, and outputs the bell sound from the speaker 24. .

  Next, when 2 seconds have elapsed after the value of the ringing number counter 13a (ringing number information) becomes “1”, the ringing number counter 13a is updated to “2”. Then, the MFP 10 refers to the ringing timing table of the table number “4” stored in the ringing timing table memory 12a, and detects the identification information storing the bell sound from the column where the ringing number information is “2”. The detected identification information is stored in the identification information detection memory 13d. At this time, since the identification information in which the bell sound is stored is “A”, the MFP 10 stores the identification information “A” in the identification information detection memory 13d. Since the identification information stored in the identification information detection memory 13d is “A”, the MFP 10 determines that the control target for outputting the ringing sound is the slave unit 151, and sends a switching signal to the slave unit 151. Send. Thereby, the subunit | mobile_unit 151 outputs a bell sound from the speaker 62. FIG.

  Then, when 0.5 second elapses after the value of the ringing number counter 13a (ringing number information) becomes “2”, the MFP 110 starts output from the speaker 24 when the value of the ringing number counter 13a is “1”. Stop the bell sound. Thereby, the bell sound output from the speaker 24 of the MFP 110 can be stopped after being superimposed on the bell sound output from the speaker 62 of the slave unit 151.

  Next, when 2 seconds have elapsed after the value of the ringing number counter 13a (ringing number information) becomes “2”, the ringing number counter 13a is updated to “3”. Then, the MFP 10 refers to the ringing timing table of the table number “4” stored in the ringing timing table memory 12a, and detects the identification information storing the bell sound from the column where the ringing number information is “3”. The detected identification information is stored in the identification information detection memory 13d. At this time, since the identification information in which the bell sound is stored is “B”, the MFP 10 stores the identification information “B” in the identification information detection memory 13d. Since the identification information stored in the identification information detection memory 13d is “B”, the MFP 10 determines that the control target for outputting the ringing sound is the slave unit 171, and sends a switching signal to the slave unit 171. Send. Thereby, handset 171 outputs a bell sound from speaker 62.

  Then, when 0.5 second has elapsed after the value of the ringing number counter 13a (ringing number information) becomes “3”, the MFP 110 transmits a switching signal when the value of the ringing number counter 13a is “2”. A switching signal is transmitted again to the slave unit 151. Then, handset 151 stops outputting the bell sound output from speaker 62. As a result, the bell sound output from the speaker 62 of the slave unit 151 can be stopped after being superimposed on the bell sound output from the speaker 62 of the slave unit 171.

  Next, when 2 seconds elapse after the value of the ringing number counter 13a (ringing number information) becomes “3”, the value of the ringing number counter 13a is updated to “4”. Then, the MFP 10 refers to the ringing timing table of the table number “4” stored in the ringing timing table memory 12a, and detects the identification information storing the bell sound from the column where the ringing number information is “4”. The detected identification information is stored in the identification information detection memory 13d. At this time, since the identification information in which the bell sound is stored is “S”, the MFP 10 stores the identification information “S” in the identification information detection memory 13d. Then, since the identification information stored in the identification information detection memory 13d is “S”, the MFP 10 determines that the control target for outputting the ringing sound is its own device, and outputs the bell sound from the speaker 24. .

  Then, when 0.5 second has elapsed since the value of the ringing number counter 13a (ringing number information) becomes “4”, the MFP 110 transmits a switching signal when the value of the ringing number counter 13a is “3”. A switching signal is transmitted again to the child device 171. Then, handset 171 stops outputting the bell sound output from speaker 62. Thus, the bell sound output from the speaker 62 of the slave unit 171 can be stopped after being superimposed on the bell sound output from the speaker 24 of the MFP 110.

  In addition, based on the above-described operation, when the value of the ringing number counter 13a (ringing number information) is “5”, the same operation as when the value of the ringing number counter 13a is “2” is executed. When the value of the number counter 13a (ringing number information) is “6”, the same operation as that performed when the value of the number of ringing counter 13a is “3” is executed in the MFP 110, the slave unit 151, and the slave unit 171. The

  The operation described above with reference to FIG. 8A will be described with reference to the timing chart of FIG. First, when a calling signal from the other party telephone is detected by the NCU 28 and the value of the ringing number counter 13a (ringing number information) becomes “1”, the MFP 10 starts outputting a bell sound from the speaker 24. Next, when 2 seconds elapse after the value of the ringing number counter 13a becomes “1”, the value is updated to the value “2” of the ringing number counter 13a. At this time, the MFP 110 transmits a switching signal to the slave unit 151. Then, handset 151 starts outputting bell sound from speaker 62 (at time t1). Then, when 0.5 second elapses after the value of the ringing number counter 13a becomes “2”, the MFP 10 stops outputting the bell sound (at time t2). Accordingly, the MFP 10 outputs a bell sound alone for 2 seconds after the value of the ringing number counter 13a becomes “1”.

  Next, when 2 seconds elapse after the value of the ringing number counter 13a (ringing number information) becomes “2”, the value of the ringing number counter 13a is updated to “3”. At this time, the MFP 110 transmits a switching signal to the slave unit 171. Then, handset 171 starts outputting a bell sound from speaker 62 (at t3). Then, when 0.5 second has elapsed since the value of the ringing number counter 13a becomes “3”, the MFP 110 transmits a switching signal to the slave unit 151. Then, handset 151 stops outputting the bell sound (at time t4). Thereby, the subunit | mobile_unit 151 outputs a bell sound independently for 2 seconds after the ringing frequency information becomes "2".

  Next, when 2 seconds elapse after the value of the ringing number counter 13a (ringing number information) becomes “3”, the value of the ringing number counter 13a is updated to “4”. Then, the MFP 110 starts outputting a bell sound from the speaker 24 (at time t5). Then, when 0.5 second has elapsed since the value of the ringing number counter 13a becomes “4”, the MFP 110 transmits a switching signal to the slave unit 171. Then, handset 171 stops outputting the bell sound (at time t6). Thereby, the subunit | mobile_unit 171 outputs a bell sound independently for 2 seconds after the value of the ringing number counter 13a becomes "3".

  In addition, based on the above-described operation, when the value of the ringing number counter 13a (ringing number information) is “5”, the same operation as when the value of the ringing number counter 13a is “2” is executed. When the value of the count counter 13a is “6”, the MFP 110, the slave unit 151, and the slave unit 171 perform the same operation as when the ringing number counter 13a is “3”. Note that the bell sound output from the MFP 110, the slave unit 151, and the slave unit 171 is repeated until a call from the partner telephone is answered.

  As described above, when the ring timing table having the table number “4” is selected from the ring timing table memory 12a by the user of the digital cordless telephone system 100, the MFP 110 determines that the order of bell sound output is MFP 110 → slave unit. 151 → Slave unit 171 → MFP 110 ... In addition to performing a part of each bell sound output from each speaker, a period in which each bell sound is output independently is generated. Control. Therefore, even if bell sounds are output from the speakers of the MFP 110, the slave unit 151, and the slave unit 171, respectively, it is possible to reduce the harsh feeling given to the user of the digital cordless telephone system 110.

  Next, the main process of the MFP 110 and the main process of the slave unit 151 (slave unit 171) for realizing the operation described above with reference to FIG. 8 will be described with reference to FIGS. First, a main process of the MFP 110 will be described with reference to FIG. FIG. 9 is a flowchart showing main processing of the MFP 110.

  This main process is a process repeatedly executed while the MFP 110 is powered on. In the main process, first, the processes of S111 to S114 are executed. Note that the processing of S111 to S114 is the same as the processing of S1 to S4 in the main processing in the MFP 10 of the first embodiment, and thus description thereof is omitted. However, in the following description, in order to facilitate understanding of the invention, it is assumed that the ringing timing table of the table number “4” shown in FIG. 8 is selected in the ringing timing table selection process (S111). I do.

  After the processing of S111 to S114, the identification information detection memory 13d is cleared (S115). Thereby, the initial setting after the start of the main process is completed.

  Next, it is determined whether or not the call signal from the partner telephone is detected by the NCU 28 (S116). When the call signal from the other party telephone is not detected (S116: No), the process of S116 is repeatedly executed. On the other hand, when the calling signal from the other party telephone is detected (S116: Yes), the value of the ringing number counter 13a is incremented by 1 (S117), and the selected ringing timing table is referenced (table number memory 14a). (Refer to the ringing timing table corresponding to the table number stored in the table), the identification information in which the content of the ringing sound is stored in the column indicated by the value of the ringing number counter 13a, that is, in the column indicated by the ringing number information. And the detected identification information is stored in the identification information memory 13d (S118).

  In the process of S118, the MFP 110 refers to the ringing timing table of the table number “4” shown in FIG. If the ringing number information (the value of the ringing number counter 13a) is “1”, the identification information “S” is detected and stored in the identification information memory 13d. If the ringing number information (ringing number counter 13a value) is “2”, the identification information “A” is detected and stored in the identification information memory 13d.

  After the process of S118, the process proceeds to S119 to S123. Note that the processes in S119 to S123 are processes for outputting a bell sound from each speaker of the MFP 110, the slave unit 151, or the slave unit 171.

  In the process of S119, it is determined whether or not the identification information stored in the identification information detection memory 13d is “S” (S119). When the identification information stored in the identification information detection memory 13d is “S” (S119: Yes), it is determined that the control target for outputting the ringing sound is the own device, and the bell sound ( A ringing sound is output (S120). When the process of S120 is executed, the MFP 110 continuously outputs the bell sound from the speaker 24 until the output of the bell sound is stopped.

  On the other hand, if the identification information stored in the identification information detection memory 13d is not “S” (S119: No), it is determined whether or not the identification information stored in the identification information detection memory 13d is “A”. (S121). When the identification information stored in the identification information detection memory 13d is “A” (S121: Yes), it is determined that the control target for outputting the ringing sound is the slave unit 151, and the identification information “A” At the same time, a switching signal is transmitted to each slave unit (S122). On the other hand, if the identification information stored in the identification information detection memory 13d is not “A” (S121: Yes), the identification information stored in the identification information detection memory 13d is “B”, so that the ringing sound is output. It is determined that the subject to be controlled is the handset 171 and a switching signal is transmitted to each handset together with the identification information “B” (S123).

  In the processes of S122 and S123, a switching signal is transmitted to each slave unit, but the MFP 110 transmits identification information together with this switching signal. Thereby, each subunit | mobile_unit can discriminate | determine from identification information whether the transmitted switching signal is a thing with respect to an own machine. Therefore, even if the switching signal is transmitted to each slave unit, the slave unit 151 and the slave unit 171 receive the switching signal to the other slave unit by mistake, and the ON / OFF of the sound output flag 54c is erroneously determined by the switching information. Will not switch. Therefore, the subunit | mobile_unit 151 and the subunit | mobile_unit 171 can output or stop the bell sound (ringing sound) output from each speaker 62 without an error.

  After the process of S120, S122 or S123, the ringing timer 13b is subtracted (S124), and the process proceeds to S125 to S130. The subtraction process of the ring timer 13b is the same as in the first embodiment. Note that the processing of S125 to S130 is performed by using the bell sound (ringing sound) output from each speaker of the MFP 110, the slave unit 151, or the slave unit 171 before updating the ringing number counter 13a. This is a process for stopping after 5 seconds.

  In the process of S125, it is determined whether or not the elapsed time from the update of the ringing number counter 13a is 0.5 seconds, that is, whether or not the elapsed time from the start of subtraction of the ringing timer 13b is 0.5 seconds. (S125). In the process of S125, in addition to the case where the elapsed time from the subtraction start of the ringing timer 13b is less than 0.5 seconds, the ringing is performed even when the elapsed time from the start of subtraction of the ringing timer 13b exceeds 0.5 seconds. It is determined that the elapsed time from the start of subtraction of the timer 13b is not 0.5 seconds, that is, "No".

  When the elapsed time from the start of subtraction of the ringing timer 13b is 0.5 seconds (S125: Yes), the output is started before the value of the ringing number counter 13a is updated (during the previous ringing number information). Since it is the timing to stop the output of the bell sound (ringing sound), the process of S126 is executed in order to identify the control target for stopping the bell sound.

  In the process of S126, 1 is subtracted from the value of the current ringing number counter 13a with reference to the selected ringing timing table (with reference to the ringing timing table corresponding to the table number stored in the table number memory 14a). The identification information in which the content of the ringing sound is stored in the column indicated by the value, that is, the column of the previous ringing number information is detected (S126). Then, it is determined whether or not the identification information has been detected (S127).

  In the process of S126, the MFP 110 refers to the ringing timing table of the table number “4” shown in FIG. If the value of the current ringing number counter 13a (ringing number information) is “2”, 1 is subtracted and the content of the ringing sound is stored in the previous ringing number information “1” column. Information “S” is detected. If the current value of the ringing number counter 13a (ringing number information) is “3”, 1 is subtracted and the content of the ringing sound is stored in the previous ringing number information “2” column. Information “A” is detected. In this case, in the process of S127, it is determined that the identification information has been detected (S127: Yes). On the other hand, if the value of the current ringing number counter 13a (ringing number information) is “1”, subtracting 1 results in the ringing number information being “0”, and the previous ringing number information “0” column is a table. The number “4” does not exist in the ringing timing table. That is, when the current value of the ringing number counter 13a (ringing number information) is “1”, before the value of the ringing number counter 13a is updated (during the previous ringing number information), the MFP 110, the slave unit No bell sound (ringing sound) is output from either 151 or handset 171. Therefore, in this case, it is determined that the identification information cannot be detected in the process of S127 (S127: No).

  If the identification information can be detected in the process of S127 (S127: Yes), it is determined whether or not the identification information detected in the process of S126 is “S” (S128). If the identification information detected in the process of S126 is “S” (S128: Yes), the bell sound was output before the value of the ringing number counter 13a was updated (during the previous ringing number information). Is the MFP 110, the bell sound output from the speaker 24 is stopped (S129). Thereafter, the process proceeds to S131.

  On the other hand, when the identification information detected in the process of S126 is not “S” (S128: No), that is, when the identification information detected in the process of S126 is “A” or “B” ( S128: No), since it is the slave unit 151 or the slave unit 171 that output the bell sound before the value of the ringing number counter 13a is updated (during the previous ringing number information), the identification detected in the process of S126 A switching signal is transmitted to each slave unit together with the information (S130). Thus, either the handset 151 or handset 171 that has output the bell sound before the value of the ringing number counter 13a is updated (during the previous ringing number information), the bell sound output from the speaker 62 is output. Stop. In addition, after the process of S130, it transfers to the process of S131.

  When the elapsed time from the start of subtraction of the ringing timer 13b is not 0.5 seconds in the process of S125 (S125: No), and when the identification information is not detected in the process of S127 (S127: No), Since it is not necessary to stop the bell sound (ringing sound), the process proceeds to S131.

  Note that the processing of S131 to S141 is the same as the processing of S10 to S20 in the main processing in the MFP 10 of the first embodiment, and thus description thereof is omitted.

  Next, with reference to FIG. 10, the main process of the subunit | mobile_unit 151 is demonstrated. FIG. 10 is a flowchart showing the main process of the slave unit 151. Note that the main process of the slave unit 171 is the same as the main process of the slave unit 151, and thus the description thereof is omitted.

  This main process is a process that is repeatedly executed while the power of the slave unit 151 is turned on. In the main process, first, the processes of S151 and S152 are executed. In addition, about the process of S151 and S152, since it is the same process as the process of S51 and S52 in the main process of the subunit | mobile_unit 51 in 1st Embodiment, the description is abbreviate | omitted. However, in the following description, in order to facilitate understanding of the invention, the ringing timing table of the table number “4” shown in FIG. 8 is shown in the ringing timing table selection process (S111) of the MFP 110 (see FIG. 9). The description will be made assuming that is selected.

  After the processing of S152, the sound information corresponding to the table number stored in the table number memory 55a is acquired from the sound information memory 53b, and the ringing sound output from the speaker 62 is set based on the acquired sound information (S153). ). In the processing of S153, since the table number “4” is stored in the table number memory 55a, the ringing sound output from the speaker 62 is set to the bell sound.

  Thereafter, the sound output flag 54d is turned off (S154). Thereby, the initial setting after the start of the main process is completed. Thereafter, it is determined whether or not the identification information transmitted from the MFP 110 has been received (S155). If the identification information has not been received (S155: No), the process of S155 is repeatedly executed. On the other hand, when the identification information is received (S155: Yes), it is determined whether or not a switching signal is received (S156). When the switching signal has not been received (S156: No), the process of S156 is repeatedly executed. On the other hand, when the switching signal is received (S156: Yes), it is determined whether or not the received identification information is the same as the identification information stored in the identification information memory 54c (S157). When the received identification information is the same as the identification information stored in the identification information memory 54c (S157: Yes), the received identification information is the identification information for the slave unit 151, and therefore received in the process of S156. The switch signal is authenticated, and the process proceeds to S158 to S160, which is a process of switching the sound output flag 54d.

  In the process of S158, it is determined whether or not the sound output flag 54d is currently on (S158). If the sound output flag 54d is currently on (S158: Yes), the sound output flag 54d is turned off (S159). On the other hand, if the sound output flag 54d is currently off (S158: No), the sound output flag 54d is turned on (S160).

  On the other hand, when the received identification information is not the same as the identification information stored in the identification information memory 54c (S157: No), the received identification information is not the identification information transmitted to the slave unit 151. , The switching signal received in S156 is not authenticated. Thereby, the process of S158-S160 is skipped and it transfers to the process of S161.

  As described above, the slave unit 151 determines whether the identification information transmitted from the MFP 110 is the same as the identification information stored in the identification information memory 54c. It is possible to determine whether or not Accordingly, the slave unit 151 can prevent the switching information to the other slave unit from being erroneously received and the on / off of the sound output flag 54c can be prevented from being erroneously switched by the switch information.

  Here, the reason why the process proceeds to the process of S161 when it is determined in the process of S157 that the received identification information is not the same as the identification information stored in the identification information memory 54c (S157: No). When it is determined that the received identification information is not the same as the identification information stored in the identification information memory 54c (S157: No), this indicates that the identification information for other slave units has been received. Indicates that a calling signal has been detected by the MFP 110. Therefore, in the processing after S161, in addition to determining the presence or absence of detection of the response signal in response to the call signal, the identification information stored in the identification information memory 54c is used to determine whether or not the response signal is received. If it is determined that they are not identical (S157: No), the process proceeds to S161.

  In the process of S161, it is determined whether or not the sound output flag 54d is on (S161). If the sound output flag 54d is on (S161: Yes), a ringing sound is output from the speaker 62 (S162). On the other hand, if the sound output flag 54d is off (S161: No), the ringing sound output from the speaker 62 is stopped (S163).

  After the processing of S162 or S163, it is determined whether or not a response signal responding to the call from the other party telephone is detected by pressing the operation key 56 or the like (S164). If no response signal is detected (S164: No), it is determined whether a response signal has been received from the MFP 110 or the handset 171 (S165). If no response signal has been received from either the MFP 110 or the slave unit 171 (S165: No), it is determined whether or not new identification information has been received (S166).

  When the identification information is not newly received (S166: No), the process proceeds to S161. Thereafter, the processing after S161 is repeatedly executed. On the other hand, when the identification information is newly received (S166: Yes), the process proceeds to S156. Thereafter, the processes after S156 are repeatedly executed.

  When a response signal is detected in the process of S164 (S164: Yes), the process proceeds to S167. If a response signal from the MFP 110 or another slave unit is received in the process of S165 (S165: Yes), the process proceeds to S172.

  Since the processing of S167 to S173 is the same as the processing of S62 to S68 in the main processing of the slave unit 51 in the first embodiment, the description thereof is omitted.

  As described above, according to the digital cordless telephone system 100 in the second embodiment, when the calling signal from the other party telephone is detected by the NCU 28, the MFP 110 responds to the value of the ringing number counter 13a (corresponding to the ringing number information). In addition to controlling the output or stop of the ringing sound by the MFP 110, the slave unit 151 (slave unit 171) repeatedly transmits a switching signal for switching the output or stop of the ringing sound to the slave unit 151 (slave unit 171). To control. That is, the MFP 110 controls the output or stop of the ringing sound by the slave unit 151 (slave unit 171) in addition to the output or stop of the ringing sound by the MFP 110. Thereby, according to the digital cordless telephone system 100 in the second embodiment, compared to the configuration of the digital cordless telephone system 1 in the first embodiment, specifically, the ringing sound of each handset is stopped. Compared with the case where control is performed by the ring timer 54b provided in each slave unit, the output or stop of the ringing sound by the MFP 110 and the output or stop of the ringing sound by the slave unit 151 (slave unit 171) are asynchronous. (The output or stop of the ringing sound by the MFP 110 and the output or stop of the ringing sound by the slave unit 151 (slave unit 171) are prevented from deviating over time).

  In addition, according to the digital cordless telephone system 100 in the second embodiment, a period in which the ringing sounds output from the MFP 110, the slave unit 151, and the slave unit 171 are independently output is provided. Therefore, even if the user of the digital cordless telephone system 100 is in a position where not only the ringing sound of the MFP 110 but also the ringing sounds of the slave unit 151 and the slave unit 171 can be heard, the synthesized sound by each ringing sound is always present. Since it is not formed, it is possible to reduce the feeling of harshness given to the user.

  Further, according to the digital cordless telephone system 100 in the second embodiment, a period in which the ringing sound output from the slave unit 151 and the slave unit 171 is output alone is provided. Therefore, even when each of the ringing sounds starts to be output when the handset 151 or handset 171 is not placed in a place where it should originally be installed, the digital cordless telephone system 100 can be relied on depending on the ringing sound output alone. The user can easily specify the location where the handset 151 or handset 171 is currently placed.

  Although the present invention has been described based on the embodiments, the present invention is not limited to the above-described embodiments, and various improvements and modifications can be easily made without departing from the spirit of the present invention. Can be inferred.

  In each of the above embodiments, the ringing timing table memory 53a and the sound information memory 53b are provided in each slave unit, and the ringing sound output from each speaker 62 is set by each of the memories. However, the present invention is not limited to this. . That is, the MFP 10 (MFP 110) may add information on the sound of sound output from each speaker 62 to the sound signal or switching signal and transmit it to each child device. And each subunit | mobile_unit should just be set as the structure which outputs a ringing sound from each speaker 62 using the information of the received ringing sound. According to this configuration, the ringing timing table memory 53a and the sound information memory 53b provided in each slave unit can be made unnecessary.

  In each embodiment, the other party telephone is a telephone apparatus connected to the telephone line network 80. However, the present invention is not limited to this. That is, the other party telephone may be an internet telephone device connected to the internet network. In this case, the MFP 10 and the MFP 110 may be provided with an Internet interface that receives an incoming signal via the Internet network.

  In each embodiment, the case where two cordless handsets are provided in the digital cordless telephone system 1 (digital cordless telephone system 100) has been described. However, in the digital cordless telephone system 1 (digital cordless telephone system 100), One slave unit may be provided, or three or four slave units may be provided. As described above, when the number of slave units changes depending on the digital cordless telephone system 1 (digital cordless telephone system 100) to be used, the identification information stored in the ringing timing table is increased according to the number of slave units to be used. At the same time, the content of the ringing sound may be set according to the increased identification information.

  In each embodiment, the ringing timing table to be used is selected by the ringing timing table selection processing (S1, S111) of the MFP 10 (MFP 110). However, the present invention is not limited to this. That is, the slave unit 51 or the slave unit 71 (slave unit 151 or slave unit 171) is provided with ringing timing table selection processing (S1, S111) for selecting a ringing timing table, and the slave unit 51 or the slave unit 71 (slave unit). 151 and the slave unit 171) may perform a ringing timing table selection process (S1, S111) to select a ringing timing table to be used.

  In the first embodiment, if the slave unit 51 (slave unit 71) fails to receive the ring signal transmitted from the MFP 10, the slave unit 51 (slave unit 71) that failed to receive the ring signal will ring. Although it was the structure which cannot output a sound, it is not restricted to this. That is, after transmitting the ringing signal, the MFP 10 receives a reception signal indicating that the ringing signal has been received from the slave unit 51 (slave unit 71), and the slave unit 51 (slave unit 71) receives the ringing signal. It is configured to determine whether or not If the MFP 10 cannot receive the reception signal from the slave unit 51 (slave unit 71) within a predetermined time, it determines that the slave unit 51 (slave unit 71) has failed to receive the ringing signal, and the slave unit It is good also as a structure which outputs the ringing sound which 51 (slave unit 71) should output instead of the sub unit 51 (slave unit 71). With this configuration, the MFP 10 can prevent each ringing sound from being output without forming a ring or a series of melodies.

  In the first embodiment, the MFP 10 transmits the ringing signal and ringing number information to each of the slave units 51 and 71 to control the output of the ringing sound by each of the slave units 51 and 71. However, the present invention is not limited to this. is not. That is, the content of the ROM 12 and the content of the RAM 13 (the ringing number counter 13a to the identification information memory 13c) including the program for realizing the flowchart of FIG. The contents of the ROM 53 including the program for realizing the flowchart and the contents of the RAM 54 (ringing frequency information reception counter 54a to identification information memory 54c) may be interchanged between the MFP 10 and the slave unit 51 (slave unit 71). That is, the operation function of the MFP 10 and the operation function of the slave unit 51 (slave unit 71) may be interchanged. This is also applicable to the second embodiment. In this configuration, when the NCU 28 of the MFP 10 detects an incoming signal from the other party telephone, a detection signal indicating the detection is transmitted from the wireless communication control circuit 22 to the slave unit 51 (slave unit 71). When the slave unit 51 (slave unit 71) receives the detection signal, the configuration shown in FIG. 5 may be executed.

  In the first embodiment, the MFP 10 transmits the ringing signal and ringing number information to each of the slave units 51 and 71 to control the output of the ringing sound by each of the slave units 51 and 71. However, the present invention is not limited to this. is not. That is, the contents of the ROM 12 and the contents of the RAM 13 (ringing number counter 13a to identification information memory 13c) including the program for realizing the flowchart of FIG. The content of the ROM 53 and the content of the RAM 54 (ringing frequency information reception counter 54a to identification information memory 54c) including the program for realizing the flowchart of FIG. In the case of this configuration, in addition to the MFP 10, the slave unit 51 (slave unit 71) can also transmit a ringing signal and ringing number information. This is also applicable to the second embodiment. In addition, when transmitting a ringing signal and ringing frequency information from the subunit | mobile_unit 51 (subunit 71), what is necessary is just to set it as the following structure. First, when the NCU 28 of the MFP 10 detects an incoming signal from the other party telephone, a detection signal indicating the detection is transmitted from the wireless communication control circuit 22 to the slave unit 51 (slave unit 71). When the slave unit 51 (slave unit 71) receives the detection signal, the configuration shown in FIG. 5 may be executed.

  In the first embodiment, for example, as shown in FIG. 2, when any ringing sound of the MFP 10, the slave unit 51, or the slave unit 71 is stopped, the MFP 10, the slave unit 51, or the slave unit 71 immediately. However, the present invention is not limited to this. That is, when the ringing sound of any of the MFP 10, the slave unit 51, and the slave unit 71 is stopped, a predetermined time (for example, 0.5 seconds) is left, and the MFP 10, the slave unit 51, or the slave unit 71. It is good also as a structure by which any ringing sound is output. Therefore, the values set in the ringing timers 13b and 54b are not limited to 2 seconds, and can be changed according to the type of ringing sound (melody) or according to the preference of the user.

  In the second embodiment, the ringing sound output from the MFP 110, the slave unit 151, and the slave unit 171 has the output volume set to zero when 2.5 seconds have elapsed from the start of output, as shown in FIG. However, it is not limited to this. That is, the output volume of the ringing sound output from the MFP 110, the slave unit 151, and the slave unit 171 starts to decrease after 2.0 seconds from the start of output, and becomes zero when 2.5 seconds from the start of output. It is good also as control. Furthermore, as a control for increasing the output volume of the ringing sound output from the MFP 110, the slave unit 151, and the slave unit 171 from the start of output to 0.5 seconds after the start of output, the predetermined volume is reached. Also good. In this case, compared with the case where the ringing timing table of the table number “4” shown in FIG. 8 is used, the volume of the synthesized sound by each ringing sound can be suppressed. Therefore, it is possible to further reduce the harsh feeling given to the user of the digital cordless telephone system 100.

  Further, in the second embodiment, when the call signal from the other party telephone is detected by the NCU 28, the MFP 110 performs different timings to each of the slave unit 151 and the slave unit 171 according to the value of the ringing number counter 13a. Thus, the slave unit 151 and the slave unit 171 are controlled by repeatedly transmitting a switching signal for switching between outputting and stopping the ringing sound, but the present invention is not limited to this. That is, the MFP 110 may control the slave unit 151 and the slave unit 171 by repeatedly transmitting a switching signal to each of the slave unit 151 and the slave unit 171 at the same timing. In this case, a standby signal for waiting for each slave unit to switch between outputting and stopping the ringing sound may be set according to the selected ringing timing table and transmitted in addition to the switching signal. Thereby, the MFP 110 can transmit the switching signal to each of the slave unit 151 and the slave unit 171 at the same timing, and the idle time of the MFP 110 can be secured.

  In the second embodiment, the table number “4” illustrated in FIG. 8 is selected and the ringing sound output from each speaker is described as a bell sound. However, the present invention is not limited to this. . That is, the digital cordless telephone system 100 of the second embodiment may be configured to output, for example, each measure of “Mr. Kuma no Mori” instead of the ringing sound output from each speaker. In the case of this configuration, first, the bell sound, which is the content of the ringing sound stored in the table number “4” shown in FIG. 8, is used for each measure of the song name “Mr. And this is stored in the ringing timing table 12a as the table number “5” or the table number “6”. Then, the MFP 110 is configured to transmit the ringing number information together with the switching signal to the slave unit 151 (slave unit 171). Further, the slave unit 151 (slave unit 171) is replaced with the sound information memory 53b provided in the ROM 53 of the slave unit 151 (slave unit 171), and the ringing timing provided in the ROM 53 of the slave unit 51 (slave unit 71). What is necessary is just to make it the structure which has the table memory 53a.
