[Embodiment of the invention]

 An embodiment of the present invention will be described below with reference to the drawings. As shown in FIGS. 2 and 3, inside the apparatus case 1 as the apparatus main body, a reading unit 2 for reading an image on an original G, printing on a recording paper Y based on the received image data. A recording unit 3 for carrying out recording is arranged, and two paper cassettes 4 and 5 for accommodating recording paper Y are vertically and removably mounted in the lower part of the apparatus case 1. A control panel section 6 is formed on the upper surface of the front of the apparatus case 1. The control panel section 6 has an upper surface on which a key input section 7 for inputting a fax number and the like and a liquid crystal for displaying various information are displayed. The display 8 is arranged.

Here, the reading unit 2 will be described. As shown in FIG. 3, the document feed tray 9 is arranged on the upper surface of the apparatus case 1, and the documents G stacked and supported on the tray 9 are assisted by the feeding. Feed is imparted by the rotation of the roller 10, and the feed roller 11 and the separation pad 12 cooperate to separate the sheets one by one and feed them between a pair of paper guides 13 in the apparatus case 1. A reading window 14 is formed in a part of the paper guide 13, and a light source 15 irradiates the original G conveyed between the paper guides 13 through the reading window 14 and a plurality of reflected lights thereof are emitted. The image on the original G is read by being guided to the image sensor 18 via the mirror 16 and the lens 17. A plurality of guide rollers 19 are disposed on the downstream side of the paper guide 13, and the rotation of these guide rollers 19 causes the original G after image reading to be ejected to the outside of the apparatus case 1 and onto the original ejection tray 20. Placed.

Next, the recording unit 3 and the paper cassettes 4 and 5 will be described. Inside the respective paper cassettes 4 and 5, a large number of recording papers Y are accommodated in a stacked state. The push-up plate 21 is tiltably arranged on the inner bottom portions of the paper cassettes 4 and 5, and a spring 22 is interposed between the push-up plate 21 and the inner bottom portions of the paper cassettes 4 and 5. Then, the spring 22 urges the push-up plate 21 to tilt upward, and the tilting pushes up the portion of the recording paper Y on the delivery side. The slide plate 23 is slidably supported on the inner bottom portions of the paper cassettes 4 and 5 in the left-right direction in FIG. 3, and the slide plate 23 can be slid according to the size of the recording paper Y in each paper cassette 4 and 5. Thus, the trailing edge position of the recording paper Y is regulated. In these paper cassettes 4 and 5, B4 size, legal size, letter size and A4 size recording paper Y can be accommodated vertically, and A5 size and B5 size recording paper Y can be accommodated horizontally. . In the present embodiment, the upper sheet cassette 4 accommodates the A4 size recording sheet Y, and the lower sheet cassette 5 accommodates the B4 size recording sheet Y.

The half-moon-shaped sheet feeding roller 24 is disposed in the apparatus case 1 so as to be positively rotatable at the upper position of each sheet cassette 4 and 5, and the rotation of each sheet feeding roller 24 causes each sheet cassette 4 to rotate. The recording paper Y is sent out one by one from the inside. The recording paper Y sent out from the upper paper cassette 4 is sent between the pair of paper guides 29 via the paper guides 25 and 26 and the pair of feed rollers 27 and 28. The recording paper Y sent out from the lower paper cassette 5 is sent between the paper guides 29 via the paper guides 30, 31, 25 and 26 and the pair of feed rollers 32, 27 and 28.

The platen roller 33 is arranged on the downstream side of the paper guide 29 so as to be positively rotatable, and a thermal head 34 is arranged so as to face the platen roller 33. A supply roll 36 and a take-up roll 37 of the ink donor film 35 are arranged in the apparatus case 1 so that they can be positively rotated, and the ink donor film 35 pulled out from the supply roll 36 is the platen roller 33 and the thermal head. It is adapted to be taken up by a take-up roll 37 via a gap between the take-up roll 34 and the roll 34. The recording paper Y passing between the paper guides 29 is fed by the rotation of the platen roller 33 and is received on the recording paper Y by the thermal head 34 while being supported on the platen roller 33. The data of the selected image is printed. The size detection sensor 50 detects the size of the set ink donor film 35 in the main scanning direction. The thermal head 34 of the present embodiment is a line print type, and its printable width in the main scanning direction is set by a switch or the like (not shown) when the thermal head 34 is assembled in the apparatus case 1. The stacker 38 is formed on the upper surface of the apparatus case 1, and the recording paper Y for which printing has been completed is ejected onto the stacker 38 via a pair of guide rollers 39.

As shown in FIGS. 3 and 4, a size display portion 40 of the recording paper Y 1 is formed on the inner surface of each of the paper cassettes 4 and 5, and recording is performed at the size display portion 40. A size detection piece 41 of the paper Y is slidably attached. Further, a size detection sensor 42 for recording paper Y is arranged in the apparatus case 1 so as to correspond to the size display section 40 of each paper cassette 4, 5, and the sensor 42 has three protruding switches. 42a is provided. These switches 42a are arranged so as to correspond to the positions of the display numbers "1, 2, 3," on the size display section 40. When the size detecting piece 41 is slid to the position of the display number corresponding to the size of the recording paper Y in the paper cassettes 4 and 5, the same detecting piece 41 is used when the paper cassettes 4 and 5 are mounted. The switch 42a facing the detection piece 41 is pressed, and the size detection signal is output from the size detection sensor 42.

For example, in the present embodiment, the B4 size recording paper Y is accommodated in the lower paper cassette 5, and in this case, as shown in FIG. 4, the size detection piece 41 has the display number of the size display section 40. The set operation is performed at the location of "2.3". When the paper cassette 5 is mounted in the apparatus case 1, the size detection piece 41 presses the two switches 42a at the positions corresponding to the display number "2.3", and the size detection sensor 42 moves the recording paper Y to B4. A detection signal indicating the size is output. The size detection signal from the size detection sensor 42 also serves as a detection signal indicating whether or not the paper cassettes 4 and 5 are mounted. Further, as shown in FIG. 2, on the front surface of the apparatus case 1, a plurality of LEDs 43 for displaying the size of the recording paper Y accommodated in each of the paper feed cassettes 4 and 5 are arranged. .

As shown in FIGS. 3 and 4, a sheet-like permanent magnet 44 is attached to the upper surface of the push-up plate 21 of each of the sheet cassettes 4 and 5, and the sheet-like permanent magnet 44 is placed so as to face the permanent magnet 44. Inside the case 1, a remaining amount detection sensor 45 as a detection unit for the recording paper Y, which is a lead switch, is arranged above the paper cassettes 4 and 5. As the recording paper Y in the paper cassettes 4 and 5 decreases, the total thickness of the recording paper Y becomes thinner and the push-up plate 21 is tilted upward to reach the remaining amount detecting sensor 45 from the permanent magnet 44. When the magnitude of the magnetic force changes, the sensor 45 outputs a detection signal when the magnitude of the magnetic force reaches or exceeds a preset value.

The sensor 46 for detecting the presence / absence of the recording paper Y is arranged above the respective paper cassettes 4 and 5 in the apparatus case 1, and is provided with a curved projection 47 which projects downward and is vertically movable and rotatable. Further, at the position corresponding to the protrusion 47, the push-up plate 21 of each of the paper cassettes 4 and 5 is provided with a slit 48. When the recording paper Y is stored in the paper cassettes 4 and 5, the lower end of the protrusion 47 of the presence / absence detection sensor 46 abuts on the upper surface of the recording paper Y to prevent the downward movement of the protrusion 47. . Then, when the recording paper Y is exhausted, the protrusion 47 is inserted into the slit 48 by its own weight and moved downward, and the presence / absence detection sensor 46 outputs a detection signal.

Next, the circuit configuration of the facsimile apparatus of this embodiment will be described. As shown in FIG. 1, a main CPU (central processing unit) 51 has a ROM (Read Only Memory) 52 storing a program for controlling the operation of the entire apparatus, and a RAM temporarily storing various information. A (random access memory) 53 is connected. The NCU (Network Control Unit) 54 has a function of controlling the connection with the telephone line, sending a dial pulse corresponding to the fax number of the other party, and detecting the incoming call. A modem (modulator / demodulator) 55 modulates and demodulates transmitted / received data and also generates a digital command signal (DCS) and a digital identification signal (DIS). The buffer memory 56 temporarily stores the received image data. The reading unit 2 is connected to the main CPU 51, and the key input unit 7 and the liquid crystal display 8 are connected via a panel controller 57. The key input section 7 is provided with a mode selection key 49 for selecting either the automatic reduction mode or the fixed reduction mode. The details of these two reduction modes will be described later.

The sub CPU 58 is connected to the main CPU 51. A ROM 60 and a RAM 59 having an area for temporarily storing image data for one page transferred from the main CPU 51 are connected to the sub CPU 58. The ROM 60 constitutes a storage means for storing a plurality of table data in which a plurality of selection patterns of the sheet cassettes 4 and 5 shown in FIGS. The ROM 60 stores the programs shown in FIGS. 17, 19 and 20. Then, under the control of the sub CPU 58 based on the program in the ROM 60, one table data is selected from a plurality of table data corresponding to each print condition such as the size of the received image data and the reduction mode. Further, according to the judgment of the sub CPU 58 based on the program, printing is performed on the optimum paper of the paper cassettes 4 and 5 based on the selected table data among the paper cassettes 4 and 5 in which the paper is stored. Therefore, the sub CPU 58 and the ROM 60 constitute a selection unit and a processing unit that perform the selection operation and the processing operation described above. Detection signals are input to the sub CPU 58 from the size detection sensor 42, the remaining amount detection sensor 45, and the presence / absence detection sensor 46 corresponding to the respective paper cassettes 4 and 5. Further, a size signal is input to the sub CPU 58 from the size detection sensor 50 of the ink donor film 35 and the size setting switch (not shown) of the thermal head 34. Further, the sub CPU 58 outputs a lighting signal to the LEDs 43 corresponding to the sheet cassettes 4 and 5, respectively. The recording unit 3 is connected to the sub CPU 58.

The ROM 60 stores a large number of table data as shown in FIGS. Although details thereof will be described later, the table data shown in FIGS. 5 to 7 corresponds to the detection signals when the sub CPU 58 inputs the detection signals from the respective sensors 42, 45 and 46, using the detection signals as addresses. This is for selecting data to be sent and sending it to the main CPU 51. These data indicate the size of the recording paper Y, the remaining amount, and the presence / absence. In addition, the table data shown in FIGS. 8 to 14 uses the size of the recording paper Y accommodated in the upper and lower paper cassettes 4 and 5 as an address, and stores the two upper and lower paper cassettes 4 and 5, respectively. This is for determining which of the recording papers Y accommodated will be printed. 7 to 14, "LT" means letter size, and "LG" means legal size. These letter-size and legal-size recording papers Y are accommodated in only one of the upper and lower paper cassettes 4 and 5, and there is no combination of "x" portions in the table data. In addition, “substitution” in the table data means that if there is no recording paper Y in either of the two paper cassettes 4 and 5, the received image data cannot be printed, so the data is recorded in the paper cassettes 4 and 5. That is, the received image data is stored in the buffer memory 56 until the paper Y is set.

When the document G is set on the document supply tray 9 and a predetermined key of the key input unit 7 is operated, the main CPU 51 operates the reading unit 2 to read the image on the document G. , And transmits the read image data via the modem 55 and the NCU 54.

The sub CPU 58 receives the size detection signal from the size detection sensor 42 corresponding to each of the paper cassettes 4 and 5 when the paper cassettes 4 and 5 are mounted. The LED 43 corresponding to is turned on to display the size of the recording paper Y accommodated in each of the paper cassettes 4 and 5.

When the size detection signal is input from the size detection sensor 42, the sub CPU 58 outputs recording paper size data to the main CPU 51 based on the table data shown in FIG. 7 stored in the ROM 60. . For example, in the present embodiment, since the A4 size recording paper Y is accommodated in the upper paper cassette 4 and the B4 size recording paper Y is accommodated in the lower paper cassette 5, the sub CPU 58 is the main CPU 51. On the other hand, B4 size data is output. That is, in the table data shown in FIG. 7, of the recording papers Y accommodated in the two paper cassettes 4 and 5, the size data of the recording paper Y having the larger width in the main scanning direction is set.

In addition, when the detection signal is not input from one or both of the size detection sensors 42, that is, when the sub CPU 58 is not attached to either one of the two paper cassettes 4 and 5. , Based on the table data of FIG. 7, a signal indicating that the paper cassette is not mounted is output to the main CPU 51. At this time, the main CPU 51 determines that the paper cassette is not mounted and stops the operation of the apparatus. In other words, the fact that the paper cassettes 4, 5 are not installed on either side means that the operator is replenishing the recording paper Y in the paper cassettes 4, 5 and the paper cassettes 4, 5 are installed immediately after the replenishment. In that case, the device has been deactivated.

When the detection signal is input from the remaining amount detection sensor 45, the sub CPU 58 sends to the main CPU 51 a signal indicating that the recording paper Y is small, based on the table data shown in FIG. 5 stored in the ROM 60. Output. That is, as shown in the figure, when a large number of recording papers Y are accommodated in the two paper cassettes 4 and 5, and no detection signal is output from the two remaining amount detection sensors 45, the sub CPU 58 is transferred to the main CPU 51. No signal is output to the main CPU 51, but the main CPU 51 determines that the recording paper Y is sufficiently contained in the paper cassette. When the amount of recording paper Y in one of the two paper cassettes 4 and 5 becomes less than the predetermined amount and the detection signal is output from the remaining amount detection sensor 45, the sub CPU 58 instructs the main CPU 51. Notify that there is not enough recording paper Y.

Further, when the detection signal is input from the presence / absence detection sensor 46, the sub CPU 58 outputs a signal indicating that the recording paper Y is exhausted based on the table data shown in FIG. 6 stored in the ROM 60. Output to the CPU 51. That is, as shown in the figure, when the recording paper Y is in one or both of the paper cassettes 4 and 5, the sub CPU 58 does not output a signal to the main CPU 51, and the main CPU 51 does not output the paper. It is determined that the recording paper Y is in the cassette. When the recording paper Y is exhausted from both the paper cassettes 4 and 5, the sub CPU 58 notifies the main CPU 51 that there is no recording paper.

Then, the main CPU 51 activates the liquid crystal display 8 based on the respective signals input from the sub CPU 58 to determine whether or not the paper cassette is loaded, the remaining amount of the recording paper Y, and the recording paper. The presence / absence information of Y is displayed.

Further, when the sub CPU 58 inputs a size signal from the size detection sensor 50 of the ink donor film 35 and the size setting switch of the thermal head 34 (not shown), the sub CPU 58 outputs the ink donor film 35 and the thermal head 34. Recognize the printable width in the main scanning direction.

When the NCU 54 detects an incoming signal from the transmitting side device, the main CPU 51 controls the NCU 54 to connect the line with the transmitting side device and bring the device into a receivable state. . Then, the main CPU 51 controls the modem 55 to send out a DIS signal to notify the receiving side device, that is, all the functions of the own device to the transmitting side device. Also, the transmission side device sends out a DCS signal in response to the DIS signal, and specifies a function selected from all the functions of the reception side device.

That is, for example, in the present embodiment, as described above, since the sub CPU 58 outputs the B4 size data to the main CPU 51, the main CPU 51 causes the recording paper Y set in the apparatus to be B4 size. When it is determined that the size is the size, the DIS signal notifies the transmission side device that it is possible to receive the document having the B4 size width as the maximum printable width in the main scanning direction.

When the image data of the original is transmitted from the transmission side device, the main CPU 51 temporarily stores the image data in the buffer memory 56, and at the same time, stores one page of the original image data in the stored image data. Image data is transferred to the sub CPU 58. The sub CPU 58 causes the RAM 59 to temporarily store the transferred image data for one page.

Then, the sub CPU 58 determines the reduction mode selected by the mode selection key 49 of the key input unit 7, the width of the image data stored in the RAM 59 in the main scanning direction, and the width of the thermal head 34 in the main scanning direction. Based on the printable width, the width of the ink donor film 35 in the main scanning direction, and the length of the image data in the sub scanning direction, the table data shown in FIGS. 8 to 14 stored in the ROM 60 is required. Select the table data of. Then, the sub CPU 58 selects either one of the two paper cassettes 4 and 5 based on the selected table data and activates the recording unit 3 to change the image data stored in the RAM 59 to the above-mentioned data. Printing is performed on the recording paper Y of the selected paper cassette 4, 5 according to the selected reduction mode.

Here, the automatic reduction mode and the fixed reduction mode selected by the mode selection key 49 will be described. First, in the automatic reduction mode, as shown in FIG. 15A, the length of the received image data for one page of the original in the sub-scanning direction is the recording paper Y in the selected paper cassette 4, 5. If the printable length is longer than the printable length of, the received image data is automatically reduced at the optimal reduction ratio so that it can be printed on one recording sheet Y, and is printed on one recording sheet Y. . Further, as shown in FIG. 15B, when the difference between the length of the received image data and the printable length of the recording paper Y exceeds the predetermined range, the received image data is divided into two recording paper Y. , Printed without being reduced.

Next, in the fixed reduction mode, unlike the automatic reduction mode, the reduction rate is designated in advance from among a plurality of fixed reduction rates, and as shown in FIG. When the difference between the length of the recording paper Y and the printable length of the recording paper Y is within the predetermined range, the received image data is reduced at the specified reduction ratio and printed on one recording paper Y. As shown in FIG. 16B, in the case where the received image data is reduced by the designated reduction ratio but does not fit on one recording sheet Y even though the difference is within the predetermined range. , The part that does not fit is not printed. As shown in FIG. 16C, when the difference between the length of the received image data and the printable length of the recording paper Y exceeds the predetermined range, the received image data is divided into two recording paper Y. Moreover, the image is reduced at the specified reduction ratio and printed.

Note that the apparatus is always set to the reduction mode of either the automatic reduction mode or the fixed reduction mode, and in any reduction mode, the sub-scanning of the received image data for one page of the original document is performed. When the length in the direction is shorter than the printable length of the recording paper Y, the received image data is not reduced, and is printed on one recording paper Y.

Next, the operation of the facsimile apparatus configured as described above will be described. Now, in this facsimile apparatus, the operation as shown in the flowchart of FIG. 17 is performed under the sub CPU 58. That is, when there is a request from the main CPU 51 for information regarding each paper cassette 4, 5 and the recording paper Y accommodated therein, the presence / absence detection sensor 46 corresponding to each paper cassette 4, 5 detects it first. A signal is taken in, and the presence / absence information of the recording paper Y 1 is output to the main CPU 51 based on the table data shown in FIG. 6 stored in the ROM 60 (steps S1 to S3).

Next, the detection signal from the remaining amount detection sensor 45 corresponding to each of the paper cassettes 4 and 5 is fetched, and the remaining amount of the recording paper Y is determined based on the table data shown in FIG. Information is output to the main CPU 51 (steps S4 to S5). Furthermore, the detection signal from the size detection sensor 42 corresponding to each paper cassette 4 and 5 is fetched, and the size information of the recording paper Y is obtained based on the table data shown in FIG. (Steps S6 to S7).

Therefore, based on these input information, the main CPU 51 recognizes the state of each of the paper cassettes 4, 5 and the recording paper Y accommodated therein. That is, the sub CPU 58 recognizes the respective states corresponding to the respective sheet cassettes 4 and 5 based on the input information from the respective sensors 42, 45 and 46, and the sub CPU 58 shown in FIG. Based on the table data shown in FIGS. 7 to 7, the respective states corresponding to the sheet cassettes 4 and 5 are output to the main CPU 51 as the state of one sheet cassette. Therefore, the main CPU 51 does not recognize the respective states corresponding to the sheet cassettes 4 and 5, but recognizes the state as one sheet cassette.

Further, at the time of reception by this facsimile apparatus, the operation as shown in the flowchart of FIG. 18 is performed under the main CPU 51. That is, when the incoming signal is input and the circuit is established, the DIS signal is sent from the modem 55 to the transmission side device, and the DCS signal is input from the transmission side device (steps S11 to S13).

Next, the image data transmitted from the transmission side device is received, and the received image data is temporarily stored in the buffer memory 56 (steps S14 to S15). Then, the stored image data is transferred to the sub CPU 58 for each page of the original document (step S16), and when all the image data is transferred, the processing of the main CPU 51 is ended.

As described above, with respect to the receiving operation, the main CPU 51 receives the image data and transfers the received image data to the sub CPU 58, and is not involved in the control of the print operation of the received image data. Absent. Further, the main CPU 51 controls the above-mentioned receiving operation, and the image reading operation and its sending operation, which will not be described in detail.

Next, in this facsimile apparatus, when printing the received image data, the operation shown in the flowcharts of FIGS. 19 and 20 is performed under the sub CPU 58. That is, when the image data for one page of the document is transferred from the main CPU 51, the image data is temporarily stored in the RAM 59 (steps S21 to S22). Then, it is judged whether the reduction mode of the apparatus is the fixed reduction mode or the automatic reduction mode (step S23). In the case of the fixed reduction mode, in the main scanning direction of the received image data stored in the RAM 59. It is determined whether the width is up to the A4 size or is larger than the width and up to the B4 size (step S24). If the width is up to A4 size, either one of the two paper cassettes 4 and 5 is selected based on the table data shown in FIG. 8 stored in the ROM 60 (step S25). For example, in this embodiment, A4 size recording paper Y is accommodated in the upper paper cassette 4 and B4 size recording paper Y is accommodated in the lower paper cassette 5, so that the A4 size recording paper Y is accommodated. The upper sheet cassette 4 in which is stored is selected.

When it is determined in step S24 that the width of the received image data in the main scanning direction is up to B4 size, whether the printable width of the thermal head 34 in the main scanning direction is the B4 size width or not. It is determined whether the width is A4 size (step S26). Then, in the case of the width of A4 size, either one of the two paper cassettes 4 and 5 is selected based on the table data shown in FIG. 14 stored in the ROM 60 (step S27). For example, in the present embodiment, the upper sheet cassette 4 containing A4 size recording paper Y is selected.

In step S26, when the printable width of the thermal head 34 in the main scanning direction is B4 size, the width of the ink donor film 35 in the main scanning direction is B4 size width or A4 size width. It is determined whether the width is wide (step S28). Then, in the case of the width of A4 size, either one of the two paper cassettes 4 and 5 is selected based on the table data shown in FIG. 14 stored in the ROM 60 (step S27). When the width is B4 size, either one of the two paper cassettes 4 and 5 is selected based on the table data shown in FIG. 9 stored in the ROM 60 (step S29).

When any one of the two paper cassettes 4 and 5 is selected in steps S25, S27, and S29, the recording unit 3 is operated and one page of the original stored in the RAM 59 is selected. The partial image data is printed on the recording paper Y of the selected paper cassette 4, 5 according to the fixed reduction mode (step S30).

On the other hand, in step S23, when the reduction mode of the apparatus is the automatic reduction mode, the width of the received image data stored in the RAM 59 in the main scanning direction is up to A4 size or larger than the width. It is determined whether the width is up to B4 size (step S31). When the width is up to A4 size, the length L of the received image data in the sub-scanning direction is a predetermined threshold value (in the present embodiment, half the length of the recording paper Y of A4 size in the sub-scanning direction). It is determined whether or not the length is smaller than the sum of (28 mm) (step S32). When the size is small, one of the two paper cassettes 4 and 5 is stored based on the table data shown in FIG. 10 stored in the ROM 60, and when the size is large, based on the table data shown in FIG. It is selected (steps S33 to S34).

In other words, for example, assuming that the two paper cassettes 4 and 5 each contain the recording paper Y of A4 size and A5 size, the recording paper Y of A4 size which is vertically accommodated in the paper cassette. The length in the sub-scanning direction is twice the length in the sub-scanning direction of the A5 size recording paper Y accommodated in the lateral direction. Therefore, if the length L of the received image data in the sub-scanning direction is the half length of the recording paper Y of A4 size in the sub-scanning direction plus some length, recording of A4 size is performed. When the image data is printed on the paper Y, a half or more blank portion is formed on the recording paper Y, and the recording paper Y becomes useless. However, when the image data is printed on the recording paper Y of A5 size based on the table data of FIG. 10, a blank portion is not formed so much on the recording paper Y, and the recording is performed. The paper Y can be effectively used. Even if the length L of the received image data in the secondary scanning direction is longer than the length of the A5 size recording paper Y within the threshold range, the image data is slightly reduced according to the automatic reduction mode described later. Since it is only printed after printing, the printed image does not become difficult to see. When the length L of the received image data in the sub-scanning direction is longer than the half length of the A4 size recording paper Y in the sub-scanning direction plus a little length, the A5 size recording paper is used. When printing on Y, there is a high possibility that image data will need to be reduced at a large reduction ratio, and the printed image may become difficult to see. In that case, based on the table data in FIG. , Image data is printed on recording paper Y of A4 size.

In step S31, when the width of the received image data in the main scanning direction is up to B4 size, the thermal head 34 is printed in the main scanning direction in the same manner as the process in the fixed reduction mode. It is determined whether the possible width and the width of the ink donor film 35 in the main scanning direction is the B4 size width or the A4 size width (steps S35 to S36). When either the printable width of the thermal head 34 in the main scanning direction or the width of the ink donor film 35 in the main scanning direction is A4 size, the table data shown in FIG. Based on this, either one of the two paper cassettes 4 and 5 is selected (step S37).

When both the printable width of the thermal head 34 in the main scanning direction and the width of the ink donor film 35 in the main scanning direction are B4 size, the length of the received image data in the sub-scanning direction is long. It is determined whether or not the size L is smaller than the length obtained by adding a predetermined threshold value (28 mm in this embodiment) to the half length of the B4 size recording paper Y in the sub-scanning direction (step S38). If it is smaller, one of the two paper cassettes 4 and 5 is selected based on the table data shown in FIG. 12 stored in the ROM 60, and if it is larger, based on the table data shown in FIG. (Steps S39 to S40).

That is, for example, assuming that the two paper cassettes 4 and 5 respectively contain the recording paper Y of B4 size and B5 size, the recording paper Y of B4 size which is vertically accommodated in the paper cassette. The length in the sub-scanning direction is twice the length in the sub-scanning direction of the B5 size recording paper Y accommodated sideways. Therefore, as in the case of the recording paper Y of A4 size or A5 size described above, the length L of the received image data in the sub-scanning direction is slightly longer than the half length of the recording paper Y of B4 size in the sub-scanning direction. If the image data is printed on the recording paper Y of B4 size for the length up to the sum of the lengths, a blank portion of almost half or more is formed on the recording paper Y, and It is useless. However, when the image data is printed on the recording paper Y of B5 size based on the table data of FIG. 12, a blank portion is not formed so much on the recording paper Y. The recording paper Y can be effectively used. Even if the length L of the received image data in the sub-scanning direction is longer than the length of the B5 size recording paper Y within the threshold range, the image data is slightly reduced according to the automatic reduction mode described later. Since it is only printed, the printed image is not difficult to see.

When any one of the two paper cassettes 4 and 5 is selected in steps S33, S34, S37, S39 and S40, the recording unit 3 is activated and the RAM 59 is stored. The stored image data for one page of the original is printed on the recording paper Y of the selected paper cassette 4, 5 according to the automatic reduction mode (step S41). If there is image data for the next page, the process returns to step S21 and the process is performed as described above (step S42).

As described above, the sub CPU 58 executes the ROM 60 based on the print conditions such as the size of the received image data transferred from the main CPU 51, the selected reduction mode, and the widths of the thermal head 34 and the ink donor film 35. The required table data is selected from the table data shown in FIGS. 8 to 14 stored in the table, and either one of the two paper cassettes 4 and 5 is selected based on the selected table data. The received image data is printed on the recording paper Y of the selected paper cassette 4, 5.

That is, the ROM 60 has an optimum paper cassette selection pattern according to the size and presence or absence of the recording paper Y in each of the paper cassettes 4 and 5 so as to correspond to the above-described many printing conditions. Are stored as table data. Therefore, when receiving the image data, it is only necessary to select the required table data corresponding to the printing conditions from the large number of table data stored in the ROM 60. The most suitable paper cassette can be easily selected according to the size and presence / absence of the recording paper Y in the paper cassettes 4 and 5, and the received image data can always be printed on the optimum recording paper Y. Therefore, it is possible to effectively use the recording paper Y without fear that the recording paper Y is wasted due to improper printing on the recording paper Y.

The present invention is not limited to the above-described embodiment. For example, the sub CPU 58 is not provided, and the main CPU 51 is configured to control the selection of the paper cassette and the printing operation. It is also possible to arbitrarily modify and embody the configuration of each unit without departing from the spirit of the invention.
