Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a telephone device that is equipped with a dial memory device and that reads a dial number from the dial memory and makes a call by operating a specific key.

[Conventional technology]

2. Description of the Related Art In recent years, many telephones are equipped with a dial memory that stores a dial number in response to a dial key operation, and the dial number is read out from the dial memory by a specific key operation to make a dial call. The function of this dial memory is used as one-touch automatic dialing or redialing. However, since the number of specific keys is limited, there is a limit to the types of dial numbers that can be stored in the dial memory. To solve this problem, a selection key or a shift key is provided in JP-A-61-1151, etc., and the number is switched according to the operation of this key, and the switching state is restored according to a timer or various operating conditions. A method to do this has been proposed.

[Problem that the invention seeks to solve]

However, providing a selection key or a shift key increases the number of required parts, increases the cost, requires more space on the operation surface, and increases the size of the operation surface.In addition, a timer or the like must be used to restore the selected state. is making this problem even more serious.

[Means for solving problems]

In order to solve such problems, this invention
The above-mentioned problem is solved by providing means for storing different numbers during on-hook dialing and off-hook dialing. However, although this method increases the amount of memory, it is different from the conventional usage method and may cause confusion or erroneous operation for the user, so in order to prevent this, the conventional usage method It also has a setting switch that allows you to select.

[Effect]

Therefore, the user can arbitrarily select which function to select.

〔Example〕

Hereinafter, details of the present invention will be explained with reference to figures showing examples.

FIG. 1 is a block diagram of a functional telephone, in which a line terminal 2 to which a telephone line (hereinafter referred to as line) 1 is connected is shown.
The switch HS ¹ and relay SP contact sp
Communication circuit (hereinafter referred to as TKC) via a parallel circuit with
3 is connected, and a dial signal sending circuit (hereinafter referred to as DSS) 4 and a monitor speaker circuit (hereinafter referred to as SPC) 5 are connected in parallel, and if off-hook is performed, TKC3 will be connected to line 1. As a result, the DC loop is closed, so that the DSS 4 can freely send a dialing signal, and in response to a response from the other party, a telephone conversation can be made using the handset 6.

In addition, a processor (hereinafter referred to as CPU) 7 such as a microprocessor is provided, and this is equipped with a fixed memory (hereinafter referred to as ROM) 8 and a variable memory (hereinafter referred to as RAM) 9, as well as a dial key (hereinafter referred to as RAM). (hereinafter referred to as DK) 10, multiple automatic dial keys (hereinafter referred to as ADK) 11 used as specific keys,
Each output is given to a speaker key (hereinafter referred to as SPK) 12, a setting switch (hereinafter referred to as SSW) 16 which sets whether or not the dial number is different during on-hook dialing and off-hook dialing, and a foot switch HS ² . and depending on these outputs
The CPU 7 executes instructions in the ROM 8, makes control decisions while accessing predetermined data from the RAM 8, and operates the dial signal generation circuit (hereinafter referred to as
DSG) 13, SPC5, control of relay SP, and
When the SPC 5 is in an operating state, the speaker indicator light (hereinafter referred to as SPL) 14 is controlled to turn on.

Therefore, if the SSW 16 is set to select different dial numbers for on-hook and off-hook, the
If you operate DK10, CPU7 will respond accordingly.
In order to control the DSG13, a dial signal using a composite audio frequency signal or a pulse signal is sent via the DSS4, and manual dialing is performed in an off-hook dial mode.
When the ADK 11 is operated without setting 0, the CPU 7 reads the corresponding dial number in the RAM 9 and controls the DSG 13 accordingly, thereby performing automatic dialing in the off-hook dial mode.

On the other hand, SPK1 without off-hook
If you operate 2, CPU 7 will relay accordingly.
In order to drive the SP, put the SPC 5 into the operating state, and turn on the SPL 14, a DC loop is closed via the contact sp, enabling on-hook monitoring by the speaker 15, and setting the on-hook dial mode. Manual dialing by the DK 10 or automatic dialing by the ADK 11 is performed in the same manner as described above.

In this example, two sets of memory areas with addresses corresponding to ADK11 are provided in RAM9 as described below.In off-hook dial mode, off-hook dial memory area _EM1 is selected, and in on-hook dial mode, off-hook dial memory area EM1 is selected. On-hook dial/memory area EM ₂ is to be selected, and by operating the registration key omitted in the diagram in any mode, and ADK11
After operating DK10, the corresponding dial number will be stored in the selected memory area.
It is stored in the address corresponding to ADK11.

In this way, by using different memory areas for the on-hook state and the off-hook state, the number of dial numbers to be stored can be increased without increasing the number of ADKs 11.

However, conventionally, there is only one type of dial number that corresponds to ADK11, and as mentioned above, if the number is different for on-hook and off-hook states,
Users who do not know this will feel confused. For this purpose, a setting switch 16 is provided, and by operating this switch, the device can be used in a conventional manner. That is, by operating this switch, only memory area _EM1 in RAM 9 is used, as will be described later. In this way, by operating the SSW 16, it is possible to either increase the number of dialed numbers or use the system as usual.

FIG. 2 is a front view showing the panel layout of the ADK 11, in which ADKs _{11 1} to 11 ₆ are used, and facing them are cards 21 ₁ to 21 ₆ for entering destinations, which are divided into upper and lower sections. For example, the upper row corresponds to memory area _EM1 , and the lower row corresponds to memory area _EM2 .

Figure 3 is a flowchart of the control situation by the CPU 7, and "SPK operation?" 101 is N (NO).
If so, a determination is made as to "Off-hook?" 102 according to the output of the foot switch HS ² , whereas if step 101 is Y (YES), the "On-hook dial mode setting" 103 sets the on-hook dial mode flag. is set, and

Next, "DK operation?" 111 is checked, and if this is N, "ADK operation?" 112 is checked.

is judged. Here, if the SSW 16 is set to dial different numbers in the on-hook state and off-hook state, step 150 is determined to be Y, and corresponding to step 103, "On-hook dial mode?" 121 is determined, and this Y of
ADK operated on the assumption that the corresponding "RAM

3, thereby controlling the DSG 13 to perform the "automatic dialing process" 131.

However, if step 150 is set to N, that is, only one type of dial number is used for ADK 11 as before, then the
The dial number reading step 123 is performed from EM ₁ , thereby controlling the DSG 13 to perform the "automatic dialing process" 131.

Further, when step 111 is Y, a "manual dialing process" 132 is performed in response to the operation of the DK 10.

After the other party answers in step 131 or 132 and the call is completed, perform an on-hook operation, or operate the SPK 12 again after dialing in the on-hook dial mode, and if ``End of call?'' 141 becomes Y, then `` Recovery process” 142
Each part is restored to its initial state.

Therefore, if the SSW16 is set to use different dial number functions during on-hook and off-hook, the
If you operate any of ADK11 ₁ to 11 ₆ ,
Step 121 becomes N, and step 123 selects an address from memory area _EM1 .
A dial call is made according to this content, but if you operate SPK12 before off-hook and then operate any of _ADK111 to _ADK116 , step 121 becomes Y and step 12
2, an address is selected from the memory area _EM2 , and dialing is performed based on the contents of this address.Without providing a selection key or shift key, _ADK111 to _ADK116 select the dial number of each of the two destinations in correspondence with each other. can be selectively and automatically called.

However, if SSW16 is set to use only one type of dial number for ADK11, step 150 will be N and RAM9 will be
Since only the EM ₁ area is used, it can be used as before.

FIG. 4 is a functional block diagram for realizing the above operation, and the CPU 7 includes a switch input detection means (hereinafter referred to as HSD) 31, a speaker key input detection means (hereinafter referred to as SKD) 32, an automatic dial Key input detection means (hereinafter referred to as AKD) 33,
It consists of a transmission mode determination means (hereinafter referred to as DMJ) 34, an address selection means (hereinafter referred to as ADS) 35, and a dial driving means (hereinafter referred to as DDR) 36, which can be used to turn on the switch HS ² by off-hook or operate the SPK 12. HSD31 or
When the SKD32 detects the detection, the DMJ34 determines the off-hook dial mode according to the detection output of the HSD31, and similarly determines the on-hook dial mode according to the detection output of the SKD32, and sends this determination result to the ADS35. ,
Sends control signal SC to each part that requires it.

If the SSW16 is set to dial different numbers when on-hook and off-hook, when you operate ADK11, this will be changed.

In order to select the addresses corresponding to ADKs 11 ₁ to 11 ₆ , the DDR 6 controls the DSG 13 in accordance with the contents and performs dialing.

However, if SSW16 is set to function as before, ADS35 will be used as a memory area.
Select only EM ₁ .

The above example is an example in which a memory area is provided in RAM 9, but it is also possible to use an integrated circuit for dialing circuits that has a speed dial area and make two destinations in the speed dial area correspond to one of ADK 11. It is often possible to prepare arbitrary addresses for dialing in each mode without dividing each memory area, add an incoming call detection circuit, and disable the automatic dialing function while answering an incoming call, or , the same prohibition may be performed once a dial call has been made, and various modifications can be made such that the present invention can be applied not only to function telephones but also to various telephone devices such as key telephone devices.

When ADK 11 is converted to redial key (hereinafter referred to as RDK) 11a in the device shown in FIG.
The same operations as described above can be performed when operating the RDK.

With this configuration, SSW 16 uses "redial memory (hereinafter referred to as RDM) in RAM 9 when on-hook".
If the DK10 is operated after off-hook, the CPU 7 will control the DSG 13 accordingly, so the composite audio frequency signal or pulse will be transmitted via the DSS 4. A dial signal is sent by a signal, and manual dialing is performed in off-hook dial mode, whereas RDK1 does not depend on DK10.
When 1a is operated, CPU7 responds to RAM
9, the dial number which is sequentially updated and stored according to the manual dialing is read out from the RDM, and based on this, the DSG 13 is controlled, and redialing is performed in the off-hook dialing mode.

On the other hand, SPK1 without off-hook
If you operate 2, CPU 7 will relay accordingly.
In order to drive the SP, bring the SPC 5 into operation, and turn on the SPL 14, a DC loop is closed via the contact sp, enabling on-hook monitoring by the speaker 15, and setting the on-hook dial mode. , manual dialing by the DK 10 is performed in the same manner as described above.

However, in this case, the dial number for the manual dial call is not stored in the RDM, and when the RDK 11a is operated, the redial call is performed using the dial number used when the manual dial call was made in the off-hook dial mode.

On the other hand, if the SSW 16 is set to function as before, the dial number of the last dialed destination will be stored in the RDM.

FIG. 5 is a flowchart of the braking operation by the CPU 7. When "Prohibit update storage to RDM during on-hook?" 151 is Y, and "On-hook dial mode?" 131 is Y, "Manual dialing process ” 132 is performed, and the dial number is not updated to the RDM. Step 151
Or, if step 131 is N, the mode is off-hook dialing, and "manual dialing process" is selected.
Update memory to RDM" 133, as before,
1 of the dial number according to DK10 and update memory to redial memory RDM.
Do this for each digit. Note that step 151 is SSW16
This is a judgment based on the setting conditions.

Therefore, when SSW16 is set to "prohibit recording of updates to RDM during on-hook", SPK
If off-hook is performed without operating 12, it becomes off-hook dial mode, and according to the operation of DK10, step 111 becomes Y and step 131 becomes N, and in addition to manual dialing, the dial number is updated and memorized by RDM, and the operation of RDK11 is performed. A redial call is made using the same dial number.

On the other hand, if you operate SPK12 before off-hook, it will become on-hook dial mode, and DK
10 steps 111 and 13
1 becomes Y, and only manual dialing is performed.
Since RDM does not memorize and the dial number in off-hook dial mode is retained as it is, even if you operate the RDK11, a redial call will be made to the destination called in off-hook dial mode, and the dial number will be dialed in on-hook dial mode. The dialing mode makes it impossible for a third party to detect the dialed number.

However, if the SSW 16 is set to perform the conventional function, the process will always follow the route of step 133, and the last dialed destination will be redialed. Therefore, the user only has to select which function to use.

FIG. 6 is a functional block diagram that realizes the above operation, and the CPU 7 includes a switch input detection means (hereinafter referred to as HSD) 31, a speaker key input detection means (hereinafter referred to as SKD) 32, a redial key input detection means (hereinafter referred to as RKD) 33a, dial key input detection means (hereinafter referred to as DKD) 38,
A transmission mode determining means (hereinafter referred to as DMJ) 34, a read control means (hereinafter referred to as MRC) 37a and a write control means (hereinafter referred to as MWC) 37b forming a memory control means (hereinafter referred to as MCC) 37, and a dial driving means (hereinafter referred to as DDR) ) 36 is configured, and the off-hook switch HS ² is turned on or the SPK 12 is operated by the HSD 31 or SKD.
32, the DMJ 34 determines the off-hook dial mode according to the detection output of the HSD 31, and similarly determines the on-hook dial mode according to the detection output of the SKD 32, and sends this determination result to the MCC 37. , sends a control signal SC to each part that requires it.

Next, if you operate DK10, this will become DKD3.
8, and according to this detection output
The DDR36 drives the DSG13 and performs manual dialing, as well as the detection output of the DKD38 and
In response to the signal indicating the determination result from DMJ34, if it is in off-hook dial mode, MWC37b
causes the RDM to perform an update storage, thereby storing the dialed number.

However, if the SSW 16 is set to prohibit updates to RDM during on-hook, the MWC 37b will not respond and update recording by RDM will not be performed.

Also, if you operate RDK11a, this will be the RKD
33a, and according to this detection output
MRC37a reads RDM and
To send to DDR36, follow this
The DDR 36 drives the DSG 13 to make a redial call.

FIG. 7 is a flowchart showing another embodiment, in which "Prohibit update to RDM in on-hook mode?" 112b and "On-hook dial mode?" 113 are added, and the same judgment as in step 131 is made. , only when step 112b is Y and step 113 is N, the process moves to steps 121 and subsequent steps and redialing is permitted, whereas if step 113 is Y, steps 111 and subsequent steps are repeated and redialing is prohibited. It is becoming. Further, if step 112b is N, step 113 is skipped.

In addition, in Figure 6, DMJ34 and MRC37a
The dotted line between RDK
11 is operated, according to the detection output of RDK33a and the signal indicating the judgment result from DMJ34,
MRC37a in on-hook dial mode
does not respond and does not make a redial call, and when the SSW 16 is set to the opposite position, it suffices to make a redial call.

Therefore, it can be arbitrarily set by the SSW 16 whether or not to use the update request to RDM when on-hook dialing.
It is sufficient to prohibit updates to RDM, and those who prefer conventional usage can set SSW16 accordingly.

Although a dedicated RDK11 is provided as a specific key, the "#" key on the DK10 or its repeated operation may also be used. The same thing can be done if only the data is stored, and update storage may be performed in accordance with either of the two modes, and storage may not be performed in accordance with the other mode.

Also, if you want to erase the redial memory, in any mode, press DK for a certain period of time.
The redial memory may be cleared when the operation No. 10 is not performed, or under specific timing conditions such as a call termination operation or the next call origination operation.

In addition, an integrated circuit for a dial circuit having a redial memory may be used without providing a redial memory in the RAM 9. In an integrated circuit having a speed dial memory, this memory may be used in the same way; In addition to using SPK12, the dial mode can be set by selecting a method according to the conditions, and can be modified in various ways, such as being applicable not only to function telephones but also to various telephone devices such as key telephone devices. .

In addition, the destination number for redialing is updated and memorized sequentially, so only the number for one destination is always stored, and if the first destination is busy, you can call the number again after calling another destination. A redial machine cannot be used to dial the first destination, and the redial number for the first destination must be operated using a dial key, which is cumbersome to use.

Therefore, steps 122 and 1 in FIG.
If the memory area that requires redialing differs depending on whether it is on-hook or not as shown in 23, if the other party is busy when dialing is performed in on-hook dial mode, the next call will be in off-hook dial mode. This makes it possible to dial and make a call to another party, and after completing the call, to make a redial call to the first party using the on-hook dial mode. However, even in this case, if you use a setting switch so that only the same memory can be used so that you can use it in a customary manner, even inexperienced users can use it without confusion.

Note that the SSW 16 may be entered as a key input using dial keys and function keys, and is particularly effective in the case of a key telephone system, and may be input from a specific handset as part of the system data, for example.

[Effects of the Invention] As explained above, in this invention, access to the dial memory is made different depending on the calling mode, so it is possible to increase the number of destination numbers stored without causing deterioration in economic efficiency or increase in size. Furthermore, depending on the operation of this setting switch, access destinations depending on the call mode can be made the same, which has the effect of enabling customary use.
