  Hereinafter, the operation of the present embodiment will be described with reference to FIGS.

  FIG. 6 shows a flow in the illuminance sensor mode until the illuminance sensor determines ambient brightness after facsimile reception.

  The main control unit 201 detects the state of the peripheral circuit at regular intervals during the standby process (S101). The user controls the key input unit 215 to monitor whether or not to perform reception control using the illuminance sensor 225 (S102). When the illuminance sensor mode is not set, if there is a setting for printing when a facsimile is received, printing processing of the received facsimile data is started. At this time, if there is no sheet, memory reception is performed (S108).

  When the function key 301 of the key input unit 215 is pressed, the main control unit 201 displays a function to be selected on the display unit 214. When the function selection state is entered, the illuminance sensor mode is selected by the selection key 310 and the illuminance sensor mode ON is set by the set key 309, the setting content is recorded in the RAM 203 and the illuminance sensor mode is started.

  When the illuminance sensor mode is set, the main control unit 201 detects whether the display unit 214 is open (FIG. 4) or closed (FIG. 5) (S103). .

  When the main control unit 201 detects that the display unit 214 is closed, the main control unit 201 stops the display process on the display unit 214 and turns off the backlight to perform a process for reducing power during standby (S109). ). When the setting of the energy saving mode is completed, the main control unit 201 sets a flag indicating that the LCD is closed to the RAM 203.

  When it is detected that the display unit 214 is open, the main control unit 201 monitors the communication processing unit 204 and monitors whether there is an incoming call from the line (S104).

  When there is no incoming call from the line 102, the control unit 201 detects the LCD close flag in the RAM 203, and when the LCD close flag is set, the control unit 201 shifts to a standby process (S111). When the LCD closing flag is not set, the display unit 214 determines that the LCD is open as shown in FIG. 4, performs timer timing processing, and performs timing processing to determine whether a predetermined time has elapsed (S112). ). If the predetermined time has not elapsed as a result of the timer timing process (S113), the process proceeds to a standby process. When the main control unit 201 detects that a predetermined time has elapsed as a result of the timer timing process (S113), the LCD display and the backlight of the display unit 214 are turned off, and the mode shifts to the energy saving mode (S114).

  During standby, when the main control unit 201 detects an incoming signal from the communication processing unit 204 (S104), it controls the analog path of the switch unit 207 to output a ring tone from the sound source unit 206, and a speaker via the switch unit 207. From 209, a ring tone is sounded. When the incoming call from the line is received a plurality of times, the main control unit 201 controls the communication processing unit 204 to close the DC loop and perform a response process for the incoming call from the line.

  After the automatic response process, the analog signal 218 from the line is input to the DSP 205 via the switch unit 207. The DSP 205 analyzes the analog signal from the line and, when detecting a CNG signal which is a facsimile transmission request, recognizes that it is facsimile reception and starts reception processing using the G3 protocol (S105). When the main control unit 201 monitors the state of the DSP 205 and detects the completion of reception (S106), the main control unit 201 detects the output of the illuminance sensor 225 and determines whether the surroundings of the device are bright or dark (S107).

  FIG. 7 is an operation flowchart when the illuminance sensor determines that the surroundings of the device are bright after facsimile reception.

  When the main control unit 201 detects the state of the illuminance sensor 225 and detects that the surroundings of the device are bright, the main control unit 201 confirms the setting of the flag in the RAM 203 and determines whether or not to perform printing by default after receiving the facsimile ( S201). When the default print processing is set after receiving the facsimile (S201), processing for printing the received facsimile data is performed, the data in the RAM 203 is decoded, output to the recording unit 211, and the print processing is performed. It performs (S211).

  After receiving the facsimile, the main control unit 201 confirms the setting of the flag in the RAM 203 and, when determining that the default printing process is not performed (S201), confirms whether the LCD close flag in the RAM 203 is set (S202). If it is confirmed that the LCD close flag is set, the main control unit 201 performs processing for notifying the user that the facsimile has been received by blinking the LED in the reception key 305 (S212).

  When the main control unit 201 determines that the LCD close flag is not set (S202), the main control unit 201 determines that the display unit 214 is open (the state in FIG. 5), and demodulates the received facsimile data. , QVGA (320 × 240) format is converted and displayed on the LCD. A general method as a display facsimile is used to display the received facsimile data on the LCD (S203).

  When the display process ends, the main control unit 201 performs a timer timing process and monitors whether a predetermined time has elapsed (S204). If the predetermined time has not elapsed, a signal indicating that the display unit 214 from the open / close detection unit 224 has been closed (state of FIG. 6) is detected (S213). When the display unit 214 is not closed, the main control unit 201 continues displaying the received facsimile data on the display unit 214.

  When the main control unit 201 receives a signal indicating that the display unit 214 is closed from the open / close detection unit 224, the main control unit 201 sets an LCD close flag in the RAM 203 (S214), and transfers the data to the LCD of the display unit 214. A process of stopping the backlight lighting process is performed (S215).

  When the main control unit 201 detects that the display on the display unit 214 has elapsed for a predetermined time, the main control unit 201 stops the display process on the display unit 214 (S205) and blinks the LED of the reception key 305 indicating that there is reception data. (S206).

  After the above processing, the main control unit 201 detects the output state of the illuminance sensor 225 and detects whether or not the signal has changed to a signal indicating that the illuminance is bright (S207). When the output of the illuminance sensor 225 changes in a direction indicating that the output has become brighter than a certain level (S207), the main control unit 201 determines that the user has performed an operation such as turning on the light when returning home, etc. Processing for displaying the received facsimile data on the display unit 214 is performed (S203).

  When the main control unit 201 detects the output state of the illuminance sensor 225 and determines that the brightness around the device has become darker than a certain level (S208), the main control unit 201 switches to processing when the illuminance sensor described later is dark.

  When the output of the illuminance sensor 225 does not change beyond a certain level, the main control unit 201 operates the display unit 214 or presses the keys of the hook detection unit 216, the document detection unit 213, and the key input units 301 to 310 by the user. Detection is performed (S209).

  If the user determines that some control processing is not performed (S209), the main control unit 201 continues the process of detecting the output state of the illuminance sensor 225 (S207).

  When the main control unit 201 monitors the state of the key input units 301 to 310 and determines that some device control has been performed by the user (S209), the main control unit 201 performs display processing requested by the user on the display unit 214 in a normal manner. Display processing is used (S210) to prompt user processing.

FIG. 8 is a flowchart when the illuminance sensor after receiving the facsimile determines that the surroundings of the device are dark.
When the main control unit 201 detects the state of the illuminance sensor 225 and detects that the surroundings of the device are dark, the main control unit 201 checks the setting of the flag in the RAM 203 and determines whether or not to perform printing by default after receiving a facsimile. (S301).

  In the case of setting to perform default printing processing after receiving the facsimile (S301), the main control unit 201 sets a default printing flag in the RAM 203 (S302). With this setting, when the surroundings of the device are dark, the received facsimile data is not printed even in the default print setting.

  After receiving the facsimile, the main control unit 201 confirms the setting of the flag in the RAM 203, and determines that the default print processing is not performed (S301), confirms whether the LCD close flag in the RAM 203 is set (S303).

  When it is confirmed that the LCD close flag is set, the main control unit 201 confirms that the sensor mode is being operated with respect to the RAM 203, and sets a flag indicating that the reception is performed when the surroundings are dark in the sensor mode. (S315) The printing process and the display process of the received data on the LCD are not performed, but only the LED of the reception key 305 is blinked (S316).

  After the processing, the main control unit 201 detects a signal indicating that the display unit 214 is opened from the open / close detection unit 224 (S317). When the main control unit 201 detects that the display unit 214 has been opened by a signal from the open / close detection unit 224 (S317), the main control unit 201 clears the LCD close flag in the RAM 203, and displays the LCD when the surroundings of the device are dark. Display processing is performed (S303, S304).

  When the state of the display unit 214 does not change, the main control unit 201 monitors a signal from the illuminance sensor unit 225 indicating that the surrounding area of the device has become bright (S318). If the surroundings do not become bright, the LED blinking process is continued (S316). When the output from the illuminance sensor 225 is monitored and it is detected that the brightness around the device has become brighter (S318), print processing (S310 to S314) described later is performed.

  If it is confirmed that the LCD closing flag is not raised, the main control unit 201 performs processing for displaying the received facsimile data on the display unit 214 (S304). At this time, the main control unit 201 performs display processing when the surroundings of the device are dark, instead of displaying when the surroundings of the normal device are bright, based on the output result of the illuminance sensor 225 (305).

  The display process when dark is performed by adjusting the brightness of the backlight in the display unit 214 stepwise based on the output result of the illuminance sensor 225, or the display process of image data when dark in the ROM 202. This is performed (S305). Image data with a higher black rate is used for image data when dark than when light. The backlight can be easily adjusted by changing the duty of the PWM signal in the main control unit 201.

  The main control unit 201 performs a time-measurement process for a predetermined time during display of received data on the LCD (S306). If the predetermined time has not elapsed (S306), it is detected whether the user operates the display unit 214 or presses the keys of the hook detection unit 216, the document detection unit 213, and the key input units 301 to 310 (S319).

  If the user determines that no control processing is performed (S319), the main control unit 201 continues the display processing of received data when the illuminance sensor 225 on the display unit 214 determines that the surroundings of the device are dark. (S305).

  When the main control unit 201 monitors the operation of the display unit 214 or the state of the hook detection unit 216, the document detection unit 213, and the key input units 301 to 310, and determines that some device control has been performed by the user (S319). A display process desired by the user is performed on the display unit 214 by adjusting the light amount of the backlight and using a display process that matches the ambient brightness (S319), and prompts the user's process. The image data used at this time is not the image data when dark but the image data when bright.

  When the main control unit 201 detects that a predetermined time has elapsed during the dark display process (S306), the main control unit 201 controls the LCD and the backlight in the display unit 214 to stop the display process (S307), and the reception key 305. The process of blinking only the LEDs inside is continued (S308).

  The main control unit 201 monitors the output signal of the illuminance sensor 225 after the blinking process of the LED, and detects whether or not the surrounding has become bright (S309). If it is not detected that the surrounding area has become bright, the clocking process for a predetermined time is continued (S306), and the LCD display stop (S307) and the user control detection process (S319) are continued.

  The main control unit 201 monitors the output of the illuminance sensor 225, and detects the presence or absence of a default print flag in the RAM 203 when detecting that the surroundings of the device are bright (S310). When there is no default print flag, the main control unit 201 switches to the process when the illuminance is bright in FIG.

  When there is a default print flag in the RAM 203, the main control unit 201 performs LCD and backlight control on the display unit 214, starts display processing to start printing (S311), and the sound source in the sound source unit 206 Is output from the speaker via the switch unit 207 (S312). The notification sound is from a single sound to speech synthesis or the like, and does not specifically define the type.

  After the processing, the facsimile reception data recorded in the RAM 203 is decrypted, and the data is transferred to the recording unit 211 to perform printing processing (S313).
