Description

  The present invention relates to a facsimile machine that reads a document and transmits data of the scanned document.

  In general, an image reading apparatus that reads an original to form image data is widely known (see, for example, Patent Document 1). Among such image reading apparatuses, there is an apparatus that reads an original with a reading unit while conveying the original with an ADF (auto document feeder).

  As a method of reading an original, there are a method of reading an original while driving the ADF and a method of reading an original placed on an original table by moving a carriage on which a reading unit is mounted. In the above-described image reading apparatus, when the ADF is driven and the document is continuously conveyed, the amount of heat generated by the motor that drives the ADF increases. Therefore, the pause time in which the operation of the motor is stopped according to the amount of heat generated by the motor. By limiting the amount of heat generated by the motor.

JP 2012-90007 A

  By the way, when the ADF of the above-described image reading apparatus is applied to a facsimile machine that reads a document and transmits the data of the read document, a motor is used to limit the amount of heat generated by the motor during the transmission of the document data. May be paused. In such a case, there is a problem that a communication error occurs in the facsimile apparatus, and it is necessary to redo the reading of the original and the transmission of the data of the read original from the beginning.

  The present invention has been made paying attention to such problems existing in the prior art. An object of the present invention is to provide a facsimile apparatus that can avoid the occurrence of a communication error due to heat generated by a drive unit that drives a document transport unit that transports a document.

Hereinafter, means for solving the above-described problems and the effects thereof will be described.
A facsimile machine that solves the above problem is driven by a drive unit, and can read a document that passes through the reading position at a reading position in the middle of the conveying path, and a document conveying section that conveys the document along a conveying path. A reading unit, a communication unit capable of immediately transmitting data of the document read by the reading unit, a temperature acquisition unit for acquiring the temperature of the driving unit,
A control unit that controls operations of the driving unit, the reading unit, and the communication unit based on the temperature of the driving unit acquired by the temperature acquisition unit, and the control unit includes the reading unit When the temperature of the drive unit acquired by the temperature acquisition unit is equal to or higher than a first threshold when the document is read and the data of the read document is immediately transmitted to the communication unit Further, after the reading operation of the original by the reading unit and the transmission operation of the original data by the communication unit are temporarily stopped, the reading operation of the original by the reading unit and the transmission of the data by the communication unit Resume operation.

According to this configuration, it is possible to avoid occurrence of a communication error due to heat generated by the driving unit that drives the document conveying unit that conveys the document.
In the facsimile apparatus, when the temperature of the drive unit acquired by the temperature acquisition unit is less than a second threshold value that is smaller than the first threshold value, the control unit reads the document by the reading unit and Time from the end of the transmission operation of the original data by the communication unit to the start of the operation of reading the next original of the original by the reading unit and the transmission operation of the next original data by the communication unit However, it is preferable to control the operations of the drive unit, the reading unit, and the communication unit so that the temperature of the drive unit becomes shorter than when the temperature of the drive unit is equal to or higher than the first threshold value.

According to this configuration, the document processing speed can be improved.
In the facsimile apparatus, when the temperature of the drive unit acquired by the temperature acquisition unit is lower than the first threshold and equal to or higher than the second threshold, the control unit is configured to read the document by the reading unit. After the reading operation and the transmission operation of the document data by the communication unit are finished, the reading operation of the next document of the document by the reading unit and the transmission operation of the data of the next document by the communication unit are started. It is preferable that the operations of the drive unit, the reading unit, and the communication unit are controlled so that the time until the temperature of the drive unit becomes longer than when the temperature of the drive unit is lower than the second threshold.

According to this configuration, it is possible to ensure the speed at which a document is faxed while using the document transport unit as much as possible.
The facsimile apparatus includes a carriage that is driven by a carriage driving unit controlled by the control unit and is movable while supporting the reading unit, and a document placing unit that places the document. The temperature of the driving unit acquired by the temperature acquisition unit before the reading unit reads the document and transmits the read document data to the communication unit is equal to or higher than the first threshold. In this case, it is preferable to have a notifying unit that notifies the reading unit that the document placed on the document placing unit is read while moving the carriage.

  According to this configuration, since the original can be faxed without using the original conveying section, it is possible to avoid interruption of the user's work.

Hereinafter, an embodiment of a facsimile apparatus will be described with reference to the drawings.
As shown in FIGS. 1 and 2, the facsimile apparatus 11 includes a main body case 12 and an opening / closing cover 13 provided on the main body case 12 so as to be openable and closable. On the side surface of the main body case 12, an operation unit 14 for a user to perform various operations of the facsimile apparatus 11 and a display unit 15 configured by a liquid crystal monitor or the like are provided. The operation unit 14 includes various operation buttons, a transmission button 14a, and the like. On the upper surface of the main body case 12, there are provided a document placement portion 16 made of a colorless and transparent glass plate, and a cover sensor 17 for detecting the open / close state of the open / close cover 13.

  As shown in FIGS. 2 and 3, the main body case 12 includes a carriage 18 configured to reciprocate in the scanning direction (left-right direction in FIG. 3) and an example of a carriage driving unit that drives the carriage 18. A carriage motor 19 and a reading unit 20 supported by the carriage 18 are accommodated. Then, with the document G placed on the document placement unit 16, the carriage motor 19 is driven to move the carriage 18 in the scanning direction, thereby reading the document G placed on the document placement unit 16. Read by the unit 20. That is, by moving the carriage 18 in the scanning direction, the original G that is placed on the original placement unit 16 and does not move is read by the reading unit 20.

  As shown in FIGS. 1 and 3, an ADF (auto document feeder) 30 as an example of a document transport unit that automatically transports a document G is provided on the open / close cover 13. The ADF 30 has a document tray 31 on which a plurality of documents G can be set in a stacked state, a transport path 32 through which the document G set on the document tray 31 is transported, and a document G transported along the transport path 32 is discharged. The discharge tray 33 is provided. The conveyance path 32 is curved in a substantially U shape, and the document tray 31 is disposed above the discharge tray 33.

  In the transport path 32, the document G set on the document tray 31 is fed downstream one by one, and the document G fed by the feed roller 34 is transported toward the discharge tray 33. A plurality of (four in this embodiment) transport roller pairs 35 are provided. The four transport roller pairs 35 are arranged at appropriate intervals along the transport path 32. The ADF 30 includes an ADF motor 36 as an example of the drive unit. The ADF motor 36 rotationally drives the feeding roller 34 and the four transport roller pairs 35.

  A position corresponding to the reading unit 20 supported by the carriage 18 at the home position (position of the carriage 18 shown in FIG. 3) in the transport path 32 is a reading position 37. The document G conveyed from the document tray 31 to the discharge tray 33 along the conveyance path 32 is supported by the carriage 18 stopped at the home position in the process of passing the reading position 37 in the middle of the conveyance path 32. Is read by the read unit 20. In this case, a portion corresponding to the carriage 18 at the home position in the document placing portion 16 forms a part of the transport path 32. The document tray 31 is provided with a document sensor 50 that detects the document G on the document tray 31.

Next, the electrical configuration of the facsimile machine 11 will be described.
As shown in FIGS. 3 and 4, the facsimile machine 11 includes a control unit 41 that controls the entire facsimile machine 11. The control unit 41 includes a microcomputer and includes a CPU, a ROM, and a RAM. The ROM stores various control programs including a program for FAX direct communication shown in the flowchart of FIG. 6, various setting data, various messages, a first threshold value K1 and a second threshold value K2, which will be described later.

  The RAM temporarily stores calculation results by the CPU and various data as processing results. And the control part 41 is a calculation part as an example of the main control part 42, the motor control part 43, the alerting | reporting part 44, and a temperature acquisition part, when CPU executes the program for FAX direct communication memorize | stored in ROM. Build 45.

  As shown in FIG. 4, the control unit 41 is electrically connected to the ADF motor 36 and the carriage motor 19 via a motor driver 46 and a motor driver 47, respectively. Furthermore, the control unit 41 is electrically connected to the display unit 15, the reading unit 20, the communication unit 48 connected to the telephone network, the operation unit 14, the cover sensor 17, the encoder 49, and the document sensor 50.

  The main control unit 42 causes the communication unit 48 to transmit the data of the document G read by the reading unit 20 to the facsimile machine of the other party connected via the telephone line network. In other words, the communication unit 48 can immediately transmit the data of the original G read by the reading unit 20 to the facsimile machine of the other party connected via the telephone line network based on a command from the main control unit 42. It is configured.

  The motor control unit 43 controls the driving of the ADF motor 36 and the carriage motor 19 via the motor driver 46 and the motor driver 47, respectively. The notification unit 44 displays various messages on the display unit 15 based on the operation of the operation unit 14 by the user. The computing unit 45 calculates the temperature T of the ADF motor 36 based on the drive current value applied to the ADF motor 36, the drive time (heat generation time) of the ADF motor 36, the stop time (heat release time), and the like. That is, the calculation unit 45 acquires the temperature T of the ADF motor 36.

  The encoder 49 outputs a pulse signal having a number of pulses proportional to the amount of movement as the carriage 18 moves in the scanning direction. Then, the control unit 41 counts the pulses of the pulse signal received from the encoder 49 and grasps the moving position of the carriage 18 in the scanning direction with the home position of the carriage 18 based on the counted value. Further, the control unit 41 grasps the open / closed state of the open / close cover 13 based on a signal transmitted from the cover sensor 17.

  In addition, the facsimile apparatus 11 has two transmission modes in which data of the read original G is transmitted while the original G is read by the reading unit 20. One of these two transmission modes is the normal mode shown in FIG. 5 (a), and the other is the weight mode shown in FIG. 5 (b). In the initial setting of the facsimile apparatus 11, the transmission mode is the normal mode. 5A and 5B, the ON position indicates the drive state of the ADF motor 36, and the OFF position indicates the stop state of the ADF motor 36.

  As shown in FIG. 5A, in the normal mode, the first original G is cued in t1 time, the first original G is waited for t2 hours, and the first original G is read. The data transmission operation of the read first original G is performed at time t3, the first original G waits for t4 hours, and then the second original G is cued.

  On the other hand, as shown in FIG. 5B, in the wait mode, the first original G is cued in t1 time, the first original G is kept waiting for t2 hours, and the first original G The reading operation and the transmission operation of the data of the read first original G are performed at time t3, the first original G is kept waiting for t5 hours, and then the second original G is cued.

  In this embodiment, t1 time is set to 1 second, t2 time is set to 1 second, t3 time is set to 17 seconds, t4 time is set to 1 second, and t5 time is set to 21 seconds. Has been. Accordingly, the time required for FAX transmission of one original G is t1 + t2 + t3 + t4 = 20 seconds in the normal mode, and t1 + t2 + t3 + t5 = 40 seconds in the wait mode. In this case, in the normal mode and the wait mode, the reading operation of the first original G after the cueing of the first original G is performed and the data transmission operation of the read first original G are performed. The time to finish is the same.

  However, in the normal mode and the weight mode, after the reading operation of the first original G and the data transmission operation of the read first original G are completed, the next second original G is cued. The time to start is different. That is, in the wait mode, after the reading operation of the first original G and the transmission operation of the data of the read first original G are completed, the reading operation of the next second original G and the reading are performed. The time until the data transmission operation for the second original G is started is much longer than in the normal mode.

  In other words, in the wait mode, the stop time (heat radiation time) of the ADF motor 36 out of 40 seconds, which is the time required for FAX communication of one original G, is t2 + t5 = 22 seconds. In the mode, the stop time (heat radiation time) of the ADF motor 36 out of 20 seconds, which is the time required for FAX transmission of one original G, is t2 + t4 = 2 seconds.

  Therefore, in the weight mode, the driving time (heat generation time) of the ADF motor 36 is the same as that in the normal mode, whereas the stop time (heat radiation time) of the ADF motor 36 is 10 times or more that in the normal mode. Therefore, in the weight mode, the temperature increase of the ADF motor 36 is significantly suppressed as compared with the normal mode.

  Next, a FAX direct communication processing routine executed by the control unit 41 will be described based on the flowchart shown in FIG. The FAX direct communication processing routine is executed by the control unit 41 when the user operates the operation unit 14 and selects the FAX direct communication mode. The FAX direct communication mode is a mode in which the document G is read by the reading unit 20 and the data of the read document G is transmitted to the other party's facsimile apparatus connected via the telephone line network. It is. That is, the FAX direct communication mode is a mode in which an operation for reading the original G and a data transmission operation for the read original G are simultaneously performed.

  When the FAX direct communication processing routine is executed, first, the control unit 41 calculates the temperature T of the ADF motor 36 (step S1). Subsequently, the control unit 41 determines whether or not the temperature T of the ADF motor 36 calculated in step S1 is equal to or higher than the first threshold value K1 stored in the ROM (step S2). The first threshold value K1 is set to a limit temperature at which the ADF motor 36 can be used.

  If the determination result in step S2 is negative, the control unit 41 determines whether or not the temperature T of the ADF motor 36 calculated in step S1 is equal to or higher than the second threshold value K2 stored in the ROM ( Step S3). The second threshold value K2 is a temperature that needs to suppress the temperature increase of the ADF motor 36, and is set to a temperature lower than the first threshold value K1. If the determination result in step S3 is affirmative, the control unit 41 changes the transmission mode from the normal mode to the wait mode (step S4).

  Subsequently, when the transmission button 14a is pressed, the control unit 41 performs FAX direct communication of the document G (step S5). On the other hand, when the determination result of step S3 is negative, the control unit 41 proceeds to step S5. That is, when the determination result in step S3 is negative, the control unit 41 performs the process in step S5 while maintaining the transmission mode in the normal mode without performing the process in step S4 when the transmission button 14a is pressed. I do.

  Subsequently, the control unit 41 determines whether or not there is a next document G on the document tray 31 (step S6). If the determination result of step S6 is affirmative, the control unit 41 proceeds to step S1. On the other hand, when the determination result of step S6 is negative, the control unit 41 ends the FAX direct communication processing routine.

  If the determination result in step S2 is affirmative, the control unit 41 determines whether or not FAX direct communication of the document G has been started (step S7). That is, when the determination result of step S2 is affirmative determination, the control unit 41 determines whether or not the transmission button 14a is pressed. If the determination result in step S7 is negative, the control unit 41 displays a message on the display unit 15 that the opening / closing cover 13 is opened and the document G is manually set on the document placement unit 16 (step S8). .

  Subsequently, the control unit 41 determines whether or not the document G is set (placed) on the document placing unit 16 (step S9). That is, the control unit 41 determines whether or not the opening / closing cover 13 has been closed after being opened once after the process of step S8. When the determination result of step S9 is negative, the control unit 41 repeatedly performs the process of step S9 until the determination result of step S9 becomes a positive determination.

  When the determination result in step S9 is affirmative and the transmission button 14a is pressed, the control unit 41 performs FAX direct communication of the document G without using the ADF 30 (step S10). Subsequently, the control unit 41 determines whether or not there is a next document G on the document tray 31 (step S11). When the determination result of step S11 is affirmative determination, the control unit 41 proceeds to step S1. On the other hand, when the determination result of step S11 is negative, the control unit 41 ends the FAX direct communication processing routine.

  If the determination result in step S7 is affirmative, the control unit 41 disconnects (stops) the FAX direct communication of the document G and displays “adjusting” on the display unit 15 (step S12). . Subsequently, the control unit 41 determines whether or not X seconds have elapsed (step S13). The X value of X seconds is set in advance for each model of the facsimile apparatus 11. When the determination result of step S13 is negative, the control unit 41 repeats the process of step S13 until the determination result of step S13 is positive.

  And the control part 41 will calculate the temperature T of ADF motor 36, if the determination result of step S13 becomes affirmation determination (step S14). Subsequently, the control unit 41 determines whether or not the temperature T of the ADF motor 36 calculated in step S14 is equal to or higher than the first threshold K1 (step S15). If the determination result of step S15 is affirmative, the control unit 41 proceeds to step S13.

  On the other hand, when the determination result of step S15 is negative, the control unit 41 deletes the “adjusting” character displayed on the display unit 15 and redials (step S16). Subsequently, the control unit 41 determines whether or not the temperature T of the ADF motor 36 calculated in step S14 is equal to or higher than the second threshold value K2 (step S17). If the determination result of step S17 is affirmative, the control unit 41 changes the transmission mode from the normal mode to the wait mode (step S18).

  Then, when the transmission button 14a is pressed, the control unit 41 performs FAX direct communication of the document G (step S19). On the other hand, when the determination result of step S17 is negative, the control unit 41 proceeds to step S19. That is, when the determination result of step S17 is negative, the control unit 41 performs the process of step S19 while maintaining the transmission mode in the normal mode without performing the process of step S18 when the transmission button 14a is pressed. I do.

  Subsequently, the control unit 41 determines whether or not there is a next document G on the document tray 31 (step S20). When the determination result of step S20 is affirmative, the control unit 41 proceeds to step S1. On the other hand, when the determination result of step S20 is negative, the control unit 41 ends the FAX direct communication processing routine.

Next, the operation of the facsimile apparatus 11 will be described.
When a plurality of originals G are faxed to the other party by FAX direct communication, each original G is set in a stacked state on the original tray 31 of the ADF 30, and then the operation unit 14 is operated to operate the FAX direct communication mode. Select. Subsequently, the operation unit 14 is operated to dial the other party, and when a line is connected to the other party, the transmission button 14a is pressed. Then, the document G is sequentially conveyed by the ADF 30 and read by the reading unit 20, and the data of the read document G is transmitted to the other party by the communication unit 48.

  At this time, as shown in FIG. 7A, if the temperature T of the ADF motor 36 is less than the second threshold K2 at the fax start time J1 of the document G (the time when the transmission button 14a is pressed), the document G While being read in the normal mode, the read data is transmitted to the other party. When the document G is repeatedly conveyed and the ADF motor 36 generates heat and the temperature T of the ADF motor 36 reaches the second threshold value K2 at time J2, the document G is read in the wait mode while being read. Will be sent to the other party. Thereby, the temperature rise of the ADF motor 36 is suppressed.

  Further, the transport of the original G is repeated and the ADF motor 36 generates heat. When the temperature T of the ADF motor 36 reaches the first threshold value K1 at time J3, the FAX direct communication of the original G is disconnected (stopped) and displayed. The text “Adjusting” is displayed in the section 15. Thereafter, when the predetermined time (X seconds) elapses and the temperature T of the ADF motor 36 becomes lower than the first threshold value K1 at time J4, the “adjusting” character displayed on the display unit 15 disappears and redialing is performed. The

  If the line is connected to the other party and the temperature T of the ADF motor 36 is lower than the second threshold value K2, when the transmission button 14a is pressed, the read data is read while the original G is read in the normal mode. Sent to the other party. At this time, if the line is connected to the other party and the temperature T of the ADF motor 36 is within the range of the second threshold value K2 or more and less than the first threshold value K1, the document G is read in the wait mode when the transmission button 14a is pressed. However, the read data is transmitted to the other party.

  Further, as shown in FIG. 7B, when a plurality of originals G are faxed to the other party by FAX direct communication, the temperature T of the ADF motor 36 at the start time J1 of the original G is the second threshold value K2. If it is within the range below the first threshold value K1, the original G is read in the wait mode, and the read data is transmitted to the other party. Thereafter, the process is the same as in the case of FIG.

  Further, as shown in FIG. 7C, when a plurality of originals G are faxed to the other party by FAX direct communication, the temperature T of the ADF motor 36 becomes the first before the fax start time J1 of the original G. If the threshold value is equal to or greater than the threshold value K1, a message indicating that the opening / closing cover 13 is opened and the document G is manually set on the document placement unit 16 is displayed on the display unit 15.

  Then, after the user opens and closes the opening / closing cover 13 and sets (places) the document G on the document placing portion 16, the ADF 30 is used when the opening / closing cover 13 is closed and the transmission button 14a is pressed. The original G is faxed to the other party by FAX direct communication. In this case, the reading unit 20 reads the document G set on the document placing unit 16 in a stopped state while moving in the scanning direction together with the carriage 18.

  As described above, in the facsimile apparatus 11 of the present embodiment, when the ADF 30 is used to fax a plurality of documents G to the other party by FAX direct communication, the ADF motor 36 generates heat and the temperature T of the ADF motor 36 is increased. Even if it rises, the fax operation is continued without causing a communication error. For this reason, interruption of the user's fax operation is avoided.

As described above, according to the embodiment described in detail, the following effects can be obtained.
(1) When the temperature T of the ADF motor 36 is equal to or higher than the first threshold value K1, the reading operation of the original G and the data transmission operation of the read original G are temporarily stopped, and then the reading of the original G is performed. The operation and the transmission operation of the read document G data are resumed. That is, when the temperature T of the ADF motor 36 becomes equal to or higher than the first threshold value K1, the fax of the document G is temporarily stopped and then the fax of the document G is resumed. For this reason, it is possible to avoid occurrence of a communication error due to heat generated by the ADF motor 36 that drives the ADF 30 that transports the document G.

  (2) When the temperature T of the ADF motor 36 is lower than the second threshold value K2, which is smaller than the first threshold value K1, the following occurs. That is, after the reading operation of the original G and the data transmission operation of the read original G are finished, the reading operation of the next original G of the original G and the transmission operation of the data of the next original G are started. Is shorter than when the temperature T of the ADF motor 36 is equal to or higher than the first threshold value K1. In other words, when the temperature of the ADF motor 36 is lower than the second threshold value K2, which is smaller than the first threshold value K1, the fax of the original document G after the fax of the original document G is started. The time is shorter than when the temperature T of the ADF motor 36 is equal to or higher than the first threshold value K1. For this reason, the processing speed when faxing the original G can be improved.

  (3) When the temperature T of the ADF motor 36 is lower than the first threshold value K1 and higher than or equal to the second threshold value K2, the following occurs. That is, after the reading operation of the original G and the data transmission operation of the read original G are finished, the reading operation of the next original G of the original G and the transmission operation of the data of the next original G are started. Is longer than when the temperature T of the ADF motor 36 is lower than the second threshold value K2. That is, after the fax of the document G when the temperature T of the ADF motor 36 is lower than the first threshold value K1 and equal to or higher than the second threshold value K2, the fax of the document G next to the document G is started. Is longer than when the temperature T of the ADF motor 36 is lower than the second threshold value K2. For this reason, since the temperature rise of the ADF motor 36 is suppressed, the usable time of the ADF 30 can be extended. Therefore, it is possible to secure the processing speed when faxing the document G while using the ADF 30 as much as possible.

  (4) When the temperature T of the ADF motor 36 is equal to or higher than the first threshold value K1 before the data of the read original G is transmitted while reading the original G, the original is placed while moving the carriage 18 in the scanning direction. A message that causes the reading unit 20 to read the document G placed on the placement unit 16 in a stopped state is displayed on the display unit 15. That is, if the temperature T of the ADF motor 36 is equal to or higher than the first threshold value K1 before faxing the original G, the original G is manually placed on the original placement unit 16 without using the ADF 30. A message to G fax is displayed on the display unit 15. For this reason, since the original G can be faxed without using the ADF 30, it is possible to avoid interruption of the user's fax operation.

(Example of change)
In addition, you may change the said embodiment as follows.
If the temperature T of the ADF motor 36 is equal to or higher than the first threshold value K1 before faxing the original G, the original G is manually placed on the original placement unit 16 without necessarily using the ADF 30. There is no need to display a message to G fax on the display unit 15.

  From the end of faxing of the original G when the temperature T of the ADF motor 36 is lower than the first threshold K1 and higher than or equal to the second threshold K2, until the start of the fax of the next original G of the original G Is not necessarily required to be longer than when the temperature T of the ADF motor 36 is lower than the second threshold value K2.

  The time from when the fax of the original G is finished to when the fax of the next original G is started after the temperature T of the ADF motor 36 is lower than the second threshold K2 smaller than the first threshold K1. Is not necessarily shorter than when the temperature T of the ADF motor 36 is equal to or higher than the first threshold value K1.

The message that the original G is manually placed on the original placement unit 16 and the original G is faxed without using the ADF 30 may be notified to the user by voice.
A temperature sensor for measuring the temperature T of the ADF motor 36 may be provided as a temperature acquisition unit.

The facsimile apparatus 11 may be mounted on a multi-function machine including a recording apparatus that performs recording (printing) on a medium such as paper.
