Description

  The present invention relates to an image communication apparatus, a control method thereof, and a program.

  When a telephone is connected to a facsimile communication apparatus, there is provided a function for switching between a facsimile communication function and a call function on a single telephone line without increasing the number of lines. In such a facsimile communication apparatus, when an incoming call is received from the outside, it is automatically discriminated whether the incoming call is a facsimile incoming call or a telephone incoming call. Is ringing.

  In such a communication apparatus having both a facsimile communication function and a telephone function, a technique that can effectively reduce the power consumption of the apparatus has been proposed. For example, Patent Document 1 describes a communication apparatus having a facsimile dedicated reception method, a facsimile priority reception method, and a telephone priority reception method. According to this, when the condition for shifting to the power saving mode is satisfied, the communication apparatus is shifted to the power saving mode after forcibly setting the facsimile reception method.

JP 2012-151718 A

  However, in the above-described prior art, when the communication apparatus connected to the telephone shifts to the power saving mode, the facsimile dedicated reception method is forcibly set, so that the telephone cannot be used in the power saving mode. Alternatively, if a call is made by operating the telephone in the power saving mode, the number is not correctly transmitted to the telephone line. In such a communication device, if the user goes off-hook with the telephone and dials immediately while waiting in the power saving mode, it takes time for the communication apparatus to return from the power saving mode, and the telephone is connected to the telephone line by a relay. The switching process to do is not in time. In such a case, since the beginning of the telephone number dialed by the user is not sent to the telephone line, it is impossible to make a call from the telephone to a desired partner.

  An object of the present invention is to solve the above-described problems of the prior art.

  A feature of the present invention is to provide a technique capable of operating a telephone and making a call to a desired partner even in a state in which the telephone is not ringing and the state is shifted to the power saving mode without ringing.

In order to achieve the above object, an image communication apparatus according to an aspect of the present invention has the following arrangement. That is,
An image communication apparatus to which a telephone is connected,
Switching means for switching the telephone and the telephone line to a connected or disconnected state;
A first control unit for controlling the operation of the image communication apparatus and causing the image communication apparatus to shift to a power saving mode when a condition for shifting to the power saving mode is satisfied;
When the mode is shifted to the power saving mode, the switching unit disconnects the telephone and the telephone line, and when the telephone is off-hooked in the power saving mode, the switching unit connects the telephone and the telephone line. And second control means for instructing the first control means to return from the power saving mode, wherein the first control means stops operating in the power saving mode, and the second The control means is operating.

  According to the present invention, there is an effect that a telephone can be operated to make a call to a desired partner even in a state in which the telephone is not ringing and the state is shifted to the power saving mode in a ringing incoming state.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments do not limit the present invention according to the claims, and all combinations of features described in the embodiments are not necessarily essential to the solution means of the present invention. .

  FIG. 1 is a block diagram illustrating a configuration of a multifunction machine 101 that is an example of an image communication apparatus according to an embodiment of the present invention.

  In addition to the facsimile communication function, the multifunction machine 101 has a copy function based on a print job from a computer via a network, an image transmission function, and the like. The multifunction machine 101 is connected to a telephone line 103, a telephone 102, and a network 104. The multi-function peripheral 101 can be used by switching between a facsimile transmission / reception function and a call function using the telephone 102. The multi-function peripheral 101 is connected to a telephone line network and an exchange through a telephone line 103. The multifunction machine 101 is connected to a network via the LAN 104, and performs data communication with a computer, a server, or the like connected to the network to transmit or print image data.

  The controller unit 201 functions as a main control unit that controls each unit of the multi-function peripheral 101, and includes a CPU 330, a ROM 331, a RAM 332, an image processing unit, and the like as illustrated in FIG. 3, and the multi-function peripheral according to a control program stored in the ROM 331. 101 is controlled. The controller unit 201 also performs image processing, data transmission / reception, data conversion, data storage, power control, and the like in the multifunction machine 101. The operation unit 202 includes a switch operated by a user, an operation panel having a touch panel function, and a display unit for displaying operation information. The scanner unit 203 scans a document, converts an image of the document into digital data, and inputs the digital data to the controller unit 201. The controller unit 201 will be described later with reference to FIG. The printer unit 204 receives the image data processed by the controller unit 201 and prints it on a sheet. The facsimile unit 205 connects the telephone line 103 and the telephone 102. The facsimile unit 205 will be described later with reference to FIG.

  A power source 206 is a power source for the multifunction machine 101, and converts AC power into DC power and supplies power to each unit of the multifunction machine 101. The power source 206 includes a first power source 207 and a second power source 208, and the power output from the power source 206 is controlled by a control signal 210 output from the power source control unit 209 of the controller unit 201.

  FIG. 2 is a block diagram illustrating a power supply path in the multifunction peripheral 101 according to the embodiment.

  The power source 206 converts AC commercial power supplied via a power plug into DC power used by the multifunction machine 101. The AC power is supplied to the first power source 207 and the second power source 208 via the main switch 211. The first power supply 207 is a power supply that supplies power even in the power saving mode in which the power consumption of the multifunction peripheral 101 is suppressed. In the normal operation mode such as when the multifunction machine 101 is activated or printing, power is supplied to each unit from both the first power source 207 and the second power source 208. The power supply control unit 209 of the controller unit 201 controls the power supply from the second power supply 208 to be stopped by the control signal 210 in the power saving mode. That is, in the power saving mode, the power supply from the second power supply 208 is stopped by the control signal 210 of the power supply control unit 209, and the power is supplied only from the first power supply 207. Power from the first power supply 207 is supplied to the controller unit 201, the facsimile unit unit 205, and the operation unit 202. In addition, power from the second power source 208 is supplied to the controller unit 201, the operation unit 202, the scanner unit 203, the printer unit 204, and the facsimile unit unit 205. As described above, power is supplied from both the first and second power sources 207 and 208 to the controller unit 201, the operation unit 202, and the facsimile unit unit 205.

  When the controller unit 201 detects that the job has been received from an external device connected to the LAN 104 or the telephone line 103 in the power saving mode, the controller unit 201 returns from the power saving mode to the normal operation mode. As a result, power supply from the second power supply 208 is started in response to the control signal 210 from the power supply control unit 209.

  FIG. 3 is a block diagram illustrating in more detail the configurations of the controller unit 201 and the facsimile unit unit 205 of the multifunction peripheral 101 according to the embodiment. In FIG. 3, a thick line indicates a power supply line.

  First, the configuration of the controller unit 201 will be described. The main controller 301 has a control CPU 330, a ROM 331, and a RAM 332, and the CPU 330 executes a program stored in the ROM 331 and controls the controller unit 201. The controller unit 201 exchanges and controls data according to each target unit in accordance with various operation modes such as copy, print, and facsimile, and executes desired image processing and the like. The main controller 301 includes a scanner I / F and a printer I / F (not shown), and communicates by connecting to the scanner unit 203 and the printer unit 204, and transmits and receives image data.

  The LAN controller 302 is connected to the LAN 104 via a cable and communicates with an external device on the network. The interrupt determination unit 303 detects an input interrupt signal and controls the power supply control unit 209, the relay 314 of the facsimile unit unit 205, and the like in cooperation with the main controller 301. When the interruption determination unit 303 detects an interruption signal by the off-hook signal 320, the incoming detection signal 321 or the like of the telephone 102, the interruption determination unit 303 notifies the main controller 301 via the interruption signal line 325. The interrupt determination unit 303 issues a control instruction to the power supply control unit 209 via the signal line 326 according to an instruction from the main controller 301 or a determination from the interrupt determination unit 303. Also, in the power saving mode, based on the off-hook signal 320 and the incoming call detection signal 321 of the telephone 102, a control instruction is given to the relay 314 that controls the telephone line 103 and the telephone 102 by the second relay control signal 324.

  When the interruption determination unit 303 detects an incoming call by the incoming call detection signal 321 from the incoming signal detection unit 312, it determines whether or not the state notification signal 322 from the main controller 301 is at a low level (power saving mode). If it is at a low level (power saving mode), the power supply control unit 209 is controlled to start supplying power from the second power supply 208. As a result, the multifunction peripheral 101 returns from the power saving mode to the normal operation mode. When an incoming call is detected by the incoming call detection signal 321, if the state notification signal 322 is at a low level and the mode setting storage unit 304 is set to use the telephone 102, the second relay control signal 324 The telephone 102 is disconnected from the telephone line 103. The status notification signal 322 is a notification signal for notifying that the main controller 301 has returned to the normal operation mode in which the modem 310 can be controlled to perform facsimile transmission / reception. If the status notification signal 322 is at a high level, the normal operation mode is indicated. If the status notification signal 322 is at a low level, it indicates that the main controller 301 is returning from the power saving mode or the power saving mode. The mode setting storage unit 304 stores settings for the facsimile reception mode of the multifunction machine 101. When the user sets the facsimile reception mode via the operation unit 202, the main controller 301 sets information corresponding to the reception mode in the mode setting storage unit 304. The first relay control signal 323 is a control signal for the main controller 301 to control switching of the relay 314.

  Next, the configuration of the facsimile unit unit 205 will be described.

  A modem (modem / demodulator) 310 converts an audio signal of the telephone line 103 into digital data, or converts digital data into audio data. The off-hook detection unit 311 detects that the handset of the telephone 102 has been lifted (off-hooked). The incoming signal detection unit 312 detects an incoming call of a facsimile or a telephone. The relay control switching circuit 313 outputs a logical sum of the first and second relay control signals 323 and 324 so that the relay 314 can be controlled from both the main controller 301 and the interrupt determination unit 303. The relay 314 is a relay switch circuit that selectively controls whether the telephone 102 and the telephone line 103 are electrically connected or disconnected. The telephone power supply unit 315 supplies power to the telephone 102 in a state where the telephone 102 is disconnected from the telephone line 103 so that an off-hook of the telephone 102 can be detected even when the telephone 102 is disconnected. The relay 314 electrically disconnects the telephone 102 and the telephone line 103 when the switch is turned on, and connects the telephone 102 and the telephone line 103 when the switch is turned off. Here, when the telephone 102 is disconnected from the telephone line 103, power is not supplied from the telephone line 103 to the telephone 102. Therefore, in this state, even if the handset of the telephone 102 is lifted, a signal cannot be output to the off-hook detection unit 311. Therefore, when the telephone 102 is disconnected from the telephone line 103, power is supplied from the telephone power supply unit 315 to the telephone 102 via the relay 314. The off-hook signal 320 is an off-hook detection signal that is output when the off-hook detection unit 311 detects that the handset of the telephone set 102 has been lifted. The incoming call detection signal 321 is a signal that is output when the incoming signal detection unit 312 detects a facsimile signal or a telephone incoming signal received via the telephone line 103.

  Since the first relay control signal 323 and the second relay control signal 324 are connected to the relay 314 via the relay control switching circuit 313, the relay 314 is controlled from both the main controller 301 and the interrupt determination unit 303. it can.

  In the power saving mode, power is supplied only to the power supply control unit 209, the LAN controller 302, the interrupt determination unit 303, the mode setting storage unit 304, the off-hook detection unit 311, the relay control switching circuit 313, and the telephone power supply unit 315. Since power is supplied to the main controller 301 only from the second power source 208, the power supply to the main controller 301 is stopped in the power saving mode. Alternatively, only a small part of the main controller 301 that can receive the return trigger is energized.

  Conventionally, when a telephone is connected to a facsimile apparatus, there are several reasons why the apparatus cannot be shifted to the power saving mode. When the telephone 102 is switched to the power saving mode in which the telephone 102 is in the silent standby state, since the telephone line 103 and the telephone 102 are not connected, it is necessary to control the connection between the telephone line 103 and the telephone 102 when returning from the power saving mode. become. When the main controller 301 controls the relay 314, if the power supply to the main controller 301 is stopped in the power saving mode, the process of connecting the telephone line 103 and the telephone 102 can be performed when returning from the power saving mode. Disappear. Therefore, in such a case, the power supply to the main controller 301 cannot be stopped in the power saving mode. For this reason, the facsimile apparatus cannot be switched to the power saving mode, or even if the facsimile apparatus is switched to the power saving mode, it is difficult to further reduce the power consumption because the power supply to the main controller 301 must be maintained. Become.

  Even if the power output of the power control unit 209 is controlled by the off-hook detection signal 320, it takes time to start the power source 206 and the main controller 301. Therefore, it takes time to connect the telephone and the telephone line by the relay 314. It will take. As a result, when the user starts the dialing operation of the telephone in the power saving mode, a situation has occurred in which it is not in time to connect the telephone and the telephone line.

  Therefore, in the embodiment, a process for solving the above-described problem when the user performs a call by operating the telephone 102 after the multifunction peripheral 101 shifts to the power saving mode will be described. Here, a description will be given particularly in the case where the facsimile unit 205 is on standby in a non-ringing standby state (a state where the telephone and the telephone line are disconnected).

  Facsimile reception settings include automatic reception, facsimile / telephone automatic switching, and manual reception. The automatic reception setting is a mode in which a facsimile signal is automatically received and is selected when only the facsimile function is used without using the external telephone 102. If the other party is a telephone, you cannot make a call. The facsimile / telephone automatic switching setting is a setting for automatically switching a reception mode by determining whether a facsimile or a telephone is received when an incoming call is received. When a facsimile signal is received, a facsimile reception is performed. Make a sound. The manual reception setting is a mode in which the telephone 102 rings when there is an incoming call, and the telephone 102 sounds for both incoming calls and facsimiles, and manual operation is required to switch to facsimile reception. This is suitable when you use a lot of telephones.

  When the automatic reception setting and the facsimile / telephone automatic switching are set as the standby state setting in the power saving mode, the telephone 102 waits in a non-sounding state where the telephone 102 does not ring when an incoming call is received. The manual reception setting is a ringing standby in which the telephone 102 rings when an incoming call is received. It should be noted that “waiting for ringing” means waiting while the telephone 102 and the telephone line 103 (exchange) are electrically connected, and “nothing” means waiting when the telephone 102 and the telephone line 103 (switch) are disconnected. It will be called “ringing standby”. In the present embodiment, the use of the telephone set 102 when the MFP 101 is in the power saving mode when the facsimile / telephone automatic switching setting is made will be described.

  FIG. 4 is a diagram illustrating an example of a setting screen for setting “facsimile / telephone automatic switching” of the multifunction peripheral 101 according to the embodiment.

  The user presses the “ON” button 401 when setting automatic switching reception between the facsimile and the telephone on this screen, and presses the “OFF” button 402 when not setting. Thereafter, if the setting is completed, an “OK” button 404 is pressed to close this screen, and a “cancel” button 403 is pressed to redo the setting.

  FIG. 5 is a flowchart for explaining an overview of processing when the multifunction peripheral 101 according to the embodiment shifts to the power saving mode and then detects an incoming call.

  First, in S501, whether or not the condition for shifting to the power saving mode is satisfied is constantly monitored in the standby state. If it is determined that the condition is satisfied, the MFP 101 is shifted to the power saving mode. In step S <b> 502, after the multifunction peripheral 101 shifts to the power saving mode, the off-hook detection unit 311, the incoming signal detection unit 312, and the interrupt determination unit 303 detect the off-hook of the telephone set 102. Thus, the relay 314 is controlled to electrically connect the telephone line 103 and the telephone 102 so that the telephone 102 can make a call. Next, the process proceeds to S503, and either the reception of the facsimile or the reception of the telephone is detected in accordance with the detection of the incoming call by the incoming signal detection unit 312 and the interruption determination unit 303, and the facsimile incoming call and the ringing of the telephone 102 are switched according to the result.

  Hereinafter, the details of the flowchart of FIG. 5 will be described in detail with reference to the flowcharts of FIGS. 6 to 8, the processing of the main controller 301 is achieved by the CPU 330 executing the program stored in the ROM 331.

  FIGS. 6A and 6B are flowcharts for explaining the processing of the interrupt determination unit 303 and the main controller 301 in the transition processing to the power saving mode in S501 of FIG. This process is performed by the interrupt determination unit 303 and the main controller 301 when the “ON” button 401 is pressed on the screen of FIG. 4 and “facsimile / telephone automatic switching” is set and the mode is shifted to the power saving mode. Processing is shown.

  First, the processing by the main controller 301 will be described with reference to FIG.

  First, in step S <b> 610, the CPU 330 satisfies the condition for shifting to the power saving mode because the operation unit 202 does not detect a user operation for a predetermined time or more, or does not receive a job from the LAN 104 or the telephone line 103 to the multi-function peripheral 101. Determine if you did. If it is determined that the conditions for shifting to the power saving mode are satisfied, the process advances to step S611, and the CPU 330 performs processing for shifting to the power saving mode, and saves the software to a non-volatile memory or an area backed up even in the power saving mode. And so on. In step S612, the CPU 330 sets the status notification signal 322 to a low level, and notifies the interrupt determination unit 303 that the controller 301 shifts to the power saving mode. Next, proceeding to S613, the CPU 330 turns off the first relay control signal 323 (low level), and enables the control of the relay 314 by the second relay control signal 324 from the interrupt determination unit 303. In step S614, the CPU 330 completes the transition to the power saving mode.

  Next, transition processing to the power saving mode by the interrupt determination unit 303 will be described with reference to the flowchart of FIG.

  First, in step S601, the state notification signal 322 from the main controller 301 is changed to a low level to determine whether the main controller 301 has shifted to the power saving mode. Sometimes stays in S601. In step S <b> 602, the interrupt determination unit 303 determines whether the mode setting storage unit 304 is set to a mode for using the telephone 102. Here, if any one of the information indicating the mode for using the telephone 102 is set, the process proceeds to S603, and if the mode for using the telephone 102 is not set, the process proceeds to S604. In step S603, the interrupt determination unit 303 turns on the second relay control signal 324 (high level), turns on the relay 314, disconnects the telephone set 102 from the telephone line 103, and sets the telephone set 102 to “no ringing standby”. The state is set and the process proceeds to S605. As a result, even when a telephone call is received in the power saving mode while the telephone 102 is connected, the telephone can be prevented from ringing before the apparatus returns from the power saving mode.

  On the other hand, in step S604, the interrupt determination unit 303 turns on the second relay control signal 324 (high level), turns off the relay 314, connects the telephone 102 and the telephone line 103, and makes the telephone 102 “ring”. The state is set to “waiting”, and the process proceeds to S605. In step S605, the interrupt determination unit 303 notifies the power supply control unit 209 that the power saving mode has been entered. As a result, the power supply by the second power source 208 is stopped, and the multifunction peripheral 101 shifts to the power saving mode.

  7A and 7B are flowcharts for explaining the processing of the interrupt determination unit 303 and the main controller 301 in the off-hook detection processing of the telephone set 102 in S502 of FIG.

  First, the off-hook detection processing of the telephone set 102 by the interrupt determination unit 303 will be described with reference to the flowchart of FIG.

  The interrupt determination unit 303 detects an off-hook of the telephone 102 in the power saving mode. The off-hook detection unit 311 inputs an off-hook detection signal 320 to the interrupt determination unit 303 when detecting an off-hook indicating that the handset of the telephone set 102 has been lifted. Thereby, the interrupt determination unit 303 can detect the off-hook of the telephone 102 even in the power saving mode. The interrupt determination unit 303 monitors the incoming interrupt signal 321 from the incoming signal detection unit 312, the signal from the mode setting storage unit 304, and the interrupt signal from the main controller 301 even in the power saving mode.

  In step S701, the interrupt determination unit 303 detects the input of the off-hook detection signal 307, and when detecting the off-hook of the telephone 102, the process proceeds to step S702. In step S <b> 702, the interrupt determination unit 303 determines control of the relay 314. Here, the interrupt determination unit 303 masks the input of the incoming call detection signal 321 after detecting the off-hook detection signal 320. As a result, occurrence of an interrupt due to the incoming call detection signal 321 is prevented. This is to prevent detection of an incoming signal before switching the relay 314. Further, the state of the state notification signal 322 from the main controller 301 is confirmed, and it is confirmed that the multi-function peripheral 101 has shifted to the power saving mode. If these conditions can be confirmed, the interrupt determination unit 303 determines that the user is trying to make a call by lifting the handset of the telephone 102. In that case, the switch of the relay 314 is turned off to connect the telephone line 103 and the telephone 102.

  The purpose of this determination in S702 is to allow the relay 314 to be controlled without a time delay when the telephone set 102 is lifted in both the normal mode and the power saving mode. In particular, in the power saving mode, the relay 314 can be controlled by the determination of the interrupt determination unit 303. Therefore, even when the user performs a dial operation immediately after lifting the handset 102, the relay 314 can be switched. .

  The interrupt determination unit 303 may be configured by a logic circuit, a programmable logic circuit, or a circuit including a CPU and a memory. In any case, the response time can be processed in a time sufficiently shorter than when the user lifts the handset of the telephone 102 and performs a dial operation.

  In step S <b> 703, the interrupt determination unit 303 determines whether to control the relay 314. If the interrupt determination unit 303 determines in step S703 that control of the relay 314 is to be performed, the process proceeds to step S704. If it is determined that control of the relay 314 is not necessary, the process ends. In step S704, the interrupt determination unit 303 turns off the second relay control signal 324 (low level) and turns off the relay 314. At this time, since the first relay control signal 323 is at a low level, the relay 314 is controlled according to the output of the interrupt determination unit 303 as the output of the relay control switching circuit 313. In this way, the telephone 102 and the telephone line are connected by the relay 314 in S704.

  In step S <b> 705, the interrupt determination unit 303 waits for detecting the on-hook of the telephone 102, and waits for the user to place the telephone 102 on the telephone 102 when the call ends. When the on-hook of the telephone 102 is detected in this way, the process proceeds to S706. In step S <b> 706, the interrupt determination unit 303 is a relay 314 switching process. When the user's call is finished, it is necessary to return to the standby state of the power saving mode. Therefore, the interrupt determination unit 303 turns on the second relay control signal 324 (high level) and turns on the relay 314. . As a result, the connection between the telephone 102 and the telephone line is disconnected, and the telephone 102 and the telephone power supply unit 315 are connected.

  FIG. 7B is a flowchart showing processing of the main controller 301 in the power saving mode. Here, the main controller 301 remains in the power saving mode in S710 and is not affected by the processing of the interrupt determination unit 303.

  8A and 8B are flowcharts for explaining the processing of the interrupt determination unit 303 and the main controller 301 in the incoming call detection processing of S503 of FIG. Here, the processing of the interrupt determination unit 303 and the main controller 301 when there is an incoming call when the multi-function peripheral 101 is waiting in the power saving mode is shown.

  FIG. 8A is a flowchart for explaining incoming call detection processing by the interrupt determination unit 303.

  In step S801, the interrupt determination unit 303 determines whether the incoming call detection signal 321 output from the incoming signal detection unit 312 is turned on (detects an incoming call). If the incoming call detection signal 321 is turned on, the process proceeds to step S802. In step S <b> 802, the interrupt determination unit 303 controls the power supply control unit 209 to turn on the power supply output of the first power supply 207 to supply power to the main controller 301, the facsimile unit unit 205, and the operation unit 202. To return to normal operation mode. In step S803, the interrupt determination unit 303 waits for the state notification signal 322 to be at a high level (the main controller 301 returns to the normal operation mode), and then proceeds to step S804. In step S804, the interrupt determination unit 303 sets the second relay control signal 324 to a low level to enable control of the relay 314 using the first relay control signal 323, and ends this process.

  FIG. 8B is a flowchart for explaining incoming call detection processing by the main controller 301.

  When power is supplied from the first power supply 207 in S802 of FIG. 8A, the main controller 301 returns from the power saving mode, and when the return is completed, the process proceeds from S810 to S812. In step S812, the CPU 330 sets the state notification signal 322 to a high level to notify the interrupt determination unit 303 that the normal operation mode has been restored. As a result, the process proceeds from S803 to S804 in the process of FIG.

  In step S812, the CPU 330 determines whether the mode stored in the mode setting storage unit 304 is set to a mode in which the standby state at the time of reception does not ring the telephone set 102. If the CPU 330 determines in S812 that the mode in which the telephone 102 is not ringed is set, the process proceeds to S813, where the first relay control signal 323 is turned on (high level) and the relay 314 is turned on. As a result, the telephone 102 and the telephone line 103 are disconnected, and a “no ringing standby” is set. On the other hand, when the mode for ringing the telephone 102 is set, the process proceeds to S814, where the first relay control signal 323 is turned off (low level) and the relay 314 is turned off. As a result, the telephone 102 and the telephone line 103 are connected to each other, and a “ringing standby” is set.

  FIG. 9 is a timing diagram illustrating the timing for detecting the off-hook of the telephone 102 in the normal operation mode and the power saving mode in the multifunction peripheral 101 according to the embodiment.

  FIG. 9A is a timing chart in the normal operation mode (when power is supplied from both the first power supply 207 and the second power supply 208).

  When the off-hook detection unit 311 detects that the handset of the telephone set 102 has been lifted at the timing T1 in the normal operation mode, the off-hook detection signal 320 is turned on. At this time, the off-hook detection signal 320 changes from the low level to the high level. Thereby, the interrupt determination unit 303 confirms the incoming call detection signal 321 and the state notification signal 322. Here, since the incoming call detection signal 321 is low level and the status notification signal 322 is high level, it is determined that the telephone 102 is off-hook in the normal operation mode. Then, the signal from the interrupt determination unit 303 to the main controller 301 is changed from the low level to the high level to notify the main controller 301 to control the relay 314. As a result, the main controller 301 sets the first relay control signal 323 to the low level to turn off the relay 314 and connect the telephone set 102 and the telephone line 103.

  In this way, in the normal operation mode, power is supplied to each block to be controlled, and the relay 314 is switched sufficiently earlier than when the user lifts the handset of the telephone 102 and operates the dial of the telephone 102. Can do. Also, when the handset of the telephone 102 is returned to the original state (on-hook), the same processing is performed to return the relay 314 to the original standby state.

  FIG. 9B is a timing chart in the power saving mode (only power supply from the first power supply 207).

  When the off-hook detection unit 311 detects that the telephone set 102 is off-hooked at the timing T2 in the power saving mode, the off-hook detection signal 320 is set to the high level. As a result, the interrupt determination unit 303 confirms that the incoming detection signal 321 is at the low level and no incoming call is received, and that the state notification signal 322 is at the low level and the main controller 301 has shifted to the power saving mode. Thereby, since it is a power saving mode, it determines that the interrupt determination part 303 is in the state which controls the relay 314. FIG.

  As a result, the second relay control signal 324 is set to the low level, the switch of the relay 314 is turned off via the relay control switching circuit 313, and the telephone set 102 and the telephone line 103 are connected. At this time, as in the normal operation mode, since power is supplied to each block to be controlled, the relay 314 causes the telephone 102 to be sufficiently faster than the user lifting the handset of the telephone 102 and performing a dial operation. And the telephone line 103 can be connected. Further, when the telephone 102 is returned to the on-hook state, the same processing can be performed, and the connection between the telephone 102 and the telephone line 103 can be returned to the original standby state by the relay 314.

  As described above, according to the embodiment, the MFP 101 can be shifted to the power saving mode even when the facsimile reception mode in which the telephone 102 is connected and “no ringing standby” is set.

  Furthermore, even in the power saving mode, by performing the relay control for controlling the off-hook detection of the telephone and the connection between the telephone and the telephone line, before the user lifts the handset of the telephone 102 and performs the dial operation, A telephone line can be connected. As a result, it is possible to avoid a situation in which switching of the relay is not in time when it is off-hooked in “no ringing standby” in the power saving mode.

  In the embodiment, automatic facsimile / telephone switching has been described as an example. However, the present invention can be similarly applied to other reception settings that are set in a power saving mode and are set to stand-by without ringing, and the same effect can be obtained.
