The present invention relates to an image recording device.

[0002]

[Prior art]

 In an image recording apparatus such as an output device for plate making, a long continuous film (or photosensitive paper) is often used in order to easily handle a photosensitive film or photosensitive paper as a recording medium. In this case, in the recording medium handling section, the continuous film wound in a roll shape is pulled out by a roller or the like, and when it reaches a predetermined size, it is cut by a cutter into a cut film, which is fed to the image recording section.

[0003]

[Problems to be solved by the device]

 When the cut film is cut out from the continuous film into predetermined lengths, a film shorter than the predetermined length (called a termination film) remains at the end. Such an end film needs to be ejected from the image recording apparatus without performing image recording, but conventionally, the end film was ejected by using a mechanism for ejecting a normal exposed film. .

However, since the mechanism for discharging the exposed film is usually designed for a normal cut film cut into a predetermined length, a termination film that does not satisfy the predetermined length is obtained. If you put it in such a mechanism, it may cause a jam. Even if it is ejected successfully, the unexposed end film will be mixed into the group of normal films that have already been exposed, which may cause problems during the automatic development process of the exposed film later. There is a nature.

The present invention has been made to solve such a problem, and an object thereof is to distinguish an end film which is less than a predetermined length from a normally exposed film so as to form an image. An object of the present invention is to provide an image recording device that prevents the occurrence of jam by discharging the recording device.

The lower guide plate of the second film guide 18 is divided into two and has an open part in the middle, and the downstream guide plate (with respect to the film flowing direction) is bent downward to form the slope 23 and the end film. It is connected to the dish 24.

As shown in FIG. 2, the transport roller 16 is driven by a transport motor 162 that can rotate in both forward and reverse directions via a clutch 161, and both the transport motor 162 and the clutch 161 are controlled by a controller 40. . A first rotary encoder 163 for detecting the rotation angle of the transport roller 16 is provided on the rotary shaft of the transport roller 16, and the output thereof is sent to the control unit 40. The cutter unit 19 is also controlled by the control unit 40. Further, the detection signals generated by the first and second film sensors 20 and 21 are sent to the control unit 40.

Returning to FIG. 1, the recording drum 30 has a drum motor 301 for rotating the recording drum 30 in both forward and backward directions at a low speed, and for fixing the leading end of the continuous film 11 (or cut film) to the recording drum 30. A pressing plate 31 (fixing means) and a recess 32 for facilitating removal of the rear end of the cut film from the recording drum 30 are provided. The pressing plate 31 is an elongated plate that is provided over the entire length of the recording drum 30 in the generatrix direction, and is rotatable about an axis that passes through substantially the center thereof and is parallel to the rotation axis of the recording drum 30. The rotation axis of the pressing plate 31 is fixed to the recording drum 30, and the pressing plate 31 moves as the recording drum 30 rotates. The pressing plate 31 is urged counterclockwise in FIG. 1 by a spring (not shown) and is normally pressed against the recording drum 30, but in FIG. 1, the right end portion ( Hereinafter, this can be locked by pressing the rear end) and leaving the left end (hereinafter referred to as the front end) from the recording drum 30. The recesses 32 are not provided continuously in the generatrix direction of the recording drum 30, but are provided intermittently at several locations.

A large number of small holes are provided on the outer peripheral surface of the recording drum 30 so that the cut film wound around the outer peripheral surface is securely fixed by vacuum suction from the inside. As shown in FIG. 2, the drum motor 301 and the vacuum pump 302 for vacuum suction are controlled by the controller 40. A second rotary encoder 303 that detects the rotation angle of the rotating shaft of the recording drum 30 is provided, and its signal is sent to the control unit 40.

A squeeze roller 33 having a rotation axis parallel to the rotation axis of the recording drum 30 is provided above the recording drum 30. The rotation axis of the squeeze roller 33 is independent of the recording drum 30, and the position of the squeeze roller 33 does not change even if the recording drum 30 rotates. However, the squeeze roller 33 can be moved up and down by an elevator mechanism (not shown), and can move toward and away from the recording drum 30. A motor 331 for raising and lowering the squeeze roller 33 is controlled by the controller 40. The squeeze roller 33 can freely rotate around its rotation axis.

The discharge portion 14 is provided with a claw 35 and a pair of first and second discharge rollers 36 and 37. The claw 35 is provided almost directly above the recording drum 30 at a position corresponding to the recess 32 of the recording drum 30. By rotating the claw 35 in the clockwise direction in FIG. 1, the claw 35 enters into the concave portion 32 of the recording drum 30, and the leading end thereof lifts the trailing end of the cut film fixed to the surface of the recording drum 30. . As shown in FIG. 2, the rotation of the claw 35 is driven by the motor 351. The pair of first and second discharge rollers 36 and 37 is driven by one discharge motor 361, and the exposed cut film separated from the surface of the recording drum 30 by the claw 35 is discharged to the film discharge port of the plate making output device. Lead. The claw rotation motor 351 and the discharge motor 361 are both controlled by the control unit 40.

The control unit 40 is composed of a microcomputer including a CPU, a ROM, a RAM, and the like, and the ROM stores a film transport program including a terminal film processing described later. Note that the film transport program may be read from an external storage device instead of being stored in the ROM. The control unit 40 controls the motors, the clutches, etc. based on the signals from the sensors, encoders, etc., according to the film transport program, so as to wind the unexposed film on the recording drums 30 and the recording drums. At 30 the film is removed after it has been exposed. An operation panel 38 is connected to the control unit 40 in addition to the above-mentioned sensors and motors. The operator inputs various commands from the keyboard of the operation panel 38, and the control unit 40 receives the processing state and the processing result. Are displayed on the display of the operation panel 38.

Next, the film transport program executed by the control unit 40 of the plate making output apparatus of this embodiment will be described with reference to the flowcharts of FIGS. 3 to 5.

(1) Wrapping Process of Unexposed Film This will be described with reference to the flowchart of FIG. First, it is determined whether or not the first film sensor 20 located between the exit roller 15 of the film magazine 12 and the transport roller 16 detects a film (step S1). If the first film sensor 20 has not detected the film, the process proceeds to step S3, and a message to load the continuous film into the film magazine 12 is displayed on the display of the operation panel 38. When the first film sensor 20 detects a film, the recording drum 30 is first placed at the winding origin position (step S2). The winding origin position of the recording drum 30 is a position where the front end of the pressing plate 31 fixed to the recording drum 30 is directly below the squeeze roller 33, as shown in FIG. As will be described later, after the previous cut film is removed from the recording drum 30, the front end of the pressing plate 31 is locked while being separated from the recording drum 30.

Next, the clutch 161 of the carry roller 16 is connected, and the carry motor 162 is rotated in the forward direction (step S4). As a result, the continuous film 11 is pulled out from the film magazine 12 and conveyed toward the recording drum 30. While the continuous film 11 is being conveyed in this way, the control unit 40 determines whether or not the first film sensor 20 cannot detect the film (step S5). If the first film sensor 20 no longer detects the film, the process proceeds to a first termination process (step S7) described later.

When the first film sensor 20 detects the film in step S5, it is next determined whether or not the second film sensor 21 provided directly above the recording drum 30 has detected the film. The determination is made (step S6). If the leading edge of the continuous film 11 has not reached the position directly above the recording drum 30, the determinations in steps S5 and S6 are repeated. When the leading edge of the continuous film 11 is detected by the second film sensor 21, the control unit 40 stops the carry motor 162 (step S8), and temporarily stops the continuous film 11 at that position. Then, the elevation motor 331 lowers the squeeze roller 33 to press the front end of the pressing plate 31. As a result, the holding plate 31 is unlocked, and the leading end of the continuous film 11 is fixed by being sandwiched between the front end of the holding plate 31 and the recording drum 30 by the action of the spring. Further, by driving the vacuum pump 302, vacuum suction of the outer peripheral surface of the recording drum 30 is started. Then, after the clutch 161 is disengaged (step S9) and the conveying roller 16 is made free, the recording drum 30 is slightly rotated clockwise by the drum motor 301, and the squeeze roller 33 is pressed against the recording drum 30 (step S10).

After that, as shown in FIG. 6, while winding the continuous film 11 around the recording drum 30, the recording drum 30 is further rotated clockwise by a predetermined amount (step S11). During this time, the continuous film 11 is pulled out from the film magazine 12, but it is determined whether or not the first film sensor 20 no longer detects the continuous film 11 when the drum motor 301 rotates by a predetermined amount (step S12). ). Here, when the first film sensor 20 no longer detects the continuous film 11, the process proceeds to step S14 and the second terminating process described later is performed.

When the film is detected by the first film sensor 20 in step S12, the cutter unit 19 is driven to cut the continuous film 11 (step S13). Then, the recording drum 30 is further rotated in the forward direction by a predetermined amount, and the cut film (cut film 25) is completely wound around the recording drum 30 to the end (step S15). After that, the squeeze roller 33 is raised and separated from the recording drum 30 (step S16). As a result, the image recording on the cut film 25 is ready.

(2) Discharging Process of Exposed Film After the cut film 25 fixed on the surface of the recording drum 30 is exposed, the exposed cut film 25 is removed as follows. Remove from. First, by driving the drum motor 301, the recording drum 30 is placed in the fixed release position. The fixing release position of the recording drum 30 is a position where the rear end of the pressing plate 31 is directly below the squeeze roller 33, as shown in FIG. Here, the squeeze roller 33 is lowered, and the rear end of the pressing plate 31 is pressed by the squeeze roller 33 to lift the front end of the pressing plate 31 and release the fixing of the front end of the cut film 25. As described above, since the pressing plate 31 can be locked with the front end thereof being lifted, the squeeze roller 33 locks the pressing plate 31 and then immediately raises it. However, since the vacuum pump 302 is still driven here, the cut film 25 does not separate from the recording drum 30.

Next, the recording drum 30 is rotated to the discharge origin position. As shown in FIG. 8, the discharge origin position of the recording drum 30 is a state in which the recesses 32 are located almost right above, and the claws 35 provided corresponding to the recesses 32 just enter the recesses 32. The position. At this position, the pawl 35 is rotated to the position shown in FIG. Then, the squeeze roller 33 is lowered and pressed against the recording drum 30 to hold the cut film 25, and the driving of the vacuum pump 302 is stopped to fix the cut film 25 to the recording drum 30 by vacuuming. To release. Then, the recording drum 30 is slightly rotated in the reverse direction so that the rear end of the cut film 25 is hooked on the pawl 35, and the pawl 35 is lifted to a position slightly higher than the outer peripheral surface of the recording drum 30. When the drum motor 301 is rotated in the opposite direction (counterclockwise in FIG. 8) in this state, the cut film 25 is separated from the recording drum 30 by the claw 35.

The cut film 25 separated from the recording drum 30 is sent to the exposed film discharge port of the plate-making output device by a first discharge roller pair 36 and a second discharge roller pair 37, as shown in FIG. I'm getting lost. The exposed film discharge port of the plate-making output device may be provided with an exposed film collection box or may be directly connected to the automatic developing device, but this embodiment applies to both cases. can do .

(3) First Termination Processing If the first film sensor 20 no longer detects the continuous film 11 before the second film sensor 21 detects the leading edge of the continuous film 11 in step S5 of FIG. The first termination process starts (step S7). In this case, the second film sensor 21 directly above the recording drum 30 does not detect the continuous film 11 (step S6), and the first film sensor 20 also stops detecting the continuous film 11 (step S5). Therefore, the leading end of the terminating film, which is the last portion of the continuous film 11, is between the first film sensor 20 and the second film sensor 21, and the trailing end is just past the first film sensor 20. It is in. In this case, as shown in the flowchart of FIG. 4, the control unit 40 first stops the carry motor 162 (step S21). However, since the transport speed of the continuous film 11 is relatively high and the end film cannot be stopped immediately, the end film overruns to some extent, and the trailing end thereof slightly advances beyond the first film sensor 20. However, since the distance between the first film sensor 20 and the transport roller 16 is set to be longer than such an overrun length, the trailing edge of the end film may come off the transport roller 16. There is no.

Next, the carry motor 162 is reversely rotated for a predetermined time (step S22). Thereby, the end film is returned to the film magazine 12. After that, the control unit 40 disengages the clutch 161 (step S23), and displays "Remove the end film and load a new continuous film" on the display of the operation panel 38 (step S24). When the operator removes the film magazine 12 according to this display, the operator can easily remove the trailing edge of the end film from the transport roller 16 to the front side (left side in FIG. 1) or drop it down. The terminal film can be taken out from the plate making output device.

(4) Second Terminal Processing When the first film sensor 20 no longer detects the continuous film 11 in step S12 of FIG. 3, the second terminal processing is started. In this case, the leading end of the continuous film 11 has already been fixed to the recording drum 30 by the pressing plate 31 (step S9) and started to be wound around the recording drum 30, but the length of the continuous film 11 is the predetermined length of the cut film 25. The length is less than the length, and the rear end of the continuous film 11 (that is, the end film) has passed through the first film sensor 20 before being cut by the cutter unit 19. In this case, since the front end of the terminating film is fixed by the pressing plate 31, the terminating film cannot be taken out simply by rotating the conveying roller 16 in the reverse direction as in the first terminating process. Therefore, in the second termination process, first, the drum motor 301 is stopped (step S31). Unlike the above case, in this case, the recording drum 30 is in the state of pulling out the continuous film (termination film) 11, but it is difficult to suddenly stop the recording drum 30 having a large mass, and the end film is over. The run amount is larger than in the case of the above-mentioned first terminal treatment. For this reason, the trailing edge of the terminating film has passed the transport roller 16 and has come to a position ahead of the opening portion of the second film guide 18 (to the recording drum 30 side).

Next, the drum motor 301 is rotated in the reverse direction to stop the recording drum 30 at the fixing release position (step S32). As described above, at the fixing release position (FIG. 7), the squeeze roller 33 is located directly above the rear end of the pressing plate 31, so that by lowering the squeeze roller 33 at this position and pressing the rear end of the pressing plate 31, The front end of the pressing plate 31 is lifted to release the fixing of the end film (step S33). Then, similar to the case of step S24, the display of the operation panel 38 displays "Please take out the end film and load a new continuous film" (step S34). By rotating the recording drum 30 in the reverse direction in step S32, the trailing edge of the terminating film advances from the slope 23 to the terminating film tray 24. The end film can be taken out from the plate making output device.

In the image output apparatus of this embodiment, the distance from the cutter unit 19 to the recording drum 30 is shortened in order to make the whole compact, and the continuous film 11 is wound before the continuous film 11 is wound on the recording drum 30. It is not possible to cut it to the specified length. Therefore, in the plate-making output apparatus of this embodiment, the continuous film 11 is processed as described above, so that the end film found to be less than the predetermined length after being wound around the recording drum 30 is automatically recorded. And eject it to the film supplier. Therefore, the short end film is not sent to the discharge unit 14 to cause a jam, and the uncut film is prevented from being mixed into the exposed cut film.

In the first embodiment, as the embodiment of claim 1, the first and second film sensors function as material length detecting means for detecting the length of the continuous film, and step S22 The control unit 40 that performs the processing of (1) functions as a termination processing unit. Further, as an embodiment of claim 2, the control unit 40 performing the processing of steps S9 to S11 functions as a winding means, and the control unit 40 performing the processing of step S32 functions as a termination processing means.

A plate making output device (second embodiment) which is an embodiment of claim 1 of the present invention will be described with reference to FIGS. 10 to 13. As shown in FIG. 10, the plate making output device of the present embodiment does not have a pressing plate on the recording drum 80, and the cut film is fixed to the outer periphery of the recording drum 80 only by vacuum suction. . Further, as the rollers for conveying the continuous film 61, in addition to the first conveying roller 66 provided between the film magazine 62 and the cutter unit 69, which is the same as in the case of the first embodiment, there is a cutter unit 69. A second transport roller 75 is provided between the recording drum 80 and the recording drum 80. As shown in FIG. 11, the first transport roller 66 and the second transport roller 75 are driven by a single transport motor 662, and the first and second transport rollers 66 and 75 respectively have the first and second rollers. Switches 661 and 751 are provided. The first transport roller 66 is provided with a rotary encoder 663 that detects the amount of rotation of the first transport roller 66.

Returning to FIG. 10, in the present embodiment, the first film sensor 70 and the first film sensor 70 and the first carrying roller 66 are respectively provided between the film magazine 62 and the first carrying roller 66 and between the second carrying roller 75 and the recording drum 80. A two-film sensor 71 is provided. Between the exit roller 65 of the film magazine 62 and the first transport roller 66, between the first transport roller 66 and the cutter of the cutter unit 69, between the cutter unit 69 and the second transport roller 75, and the second A first film guide 76, a second film guide 77, a third film guide 78 and a fourth film guide 79 are provided between the transport roller 75 and the recording drum 80. Of these, the lower guide plate of the third film guide 78, which is between the cutter unit 69 and the second transport roller 75, is divided into two and an open portion is provided in the middle, and the downstream side (recording drum) The guide plate on the 80 side) is connected via a slope 73 to a terminal film collection box 74 provided below the film magazine 62.

The connection relationship between the control unit 90 of this embodiment and the sensor, motor, etc. is as shown in FIG. In the case of this embodiment, the control unit 90 processes the end film as shown in the flowchart of FIG. First, the transport motor 662 is rotated in the forward direction, and the first and second clutches 661 and 751 are brought into the connected state (step S41). As a result, the first and second transport rollers 66 and 75 rotate, and the continuous film 61 is pulled out from the film magazine 62. Next, it is determined whether the first film sensor 70 detects a film (step S42). If the first film sensor 70 no longer detects the film, the process proceeds to the terminating process described later (step S44).

When the first film sensor 70 detects the film in step S42, the process proceeds to step S43, and the pulse signal from the rotary encoder 663 that detects the rotation amount of the first transport roller 66 is counted. In the next step S45, it is determined whether or not the number of counts has reached a predetermined number (that is, whether or not the continuous film 61 has been conveyed by a predetermined amount). If the count number of the rotary encoder 663 is less than the predetermined number, the process returns to step S42 to determine whether or not the continuous film 61 is exhausted by the first film sensor 70 while the continuous film 61 is being conveyed by both the conveying rollers 66 and 75. Is determined (step S42).

When the count number of the rotary encoder 663 reaches a predetermined number, the process proceeds to step S46 to perform a normal winding process. Here, vacuum suction of the recording drum 80, winding of the continuous film 61, pressing by a squeeze roller (not shown), cutting by the cutter unit 69, etc. are performed, but details are omitted. The termination treatment of this embodiment can be adopted regardless of which winding method is used.

When the first film sensor 70 no longer detects the film in step S42, the termination process shown by the flowchart of FIG. 13 is started. In this case, since the length of the continuous film 61 is less than the predetermined length corresponding to the predetermined number of encoder pulses, the control unit 90 first stops the transport motor 662, and the first clutch 661 and The second clutch 751 is disengaged (step S51). As a result, the continuous film 61 that is less than the predetermined length, that is, the end film, slightly overruns and then stops. However, since the first film sensor 70 is attached so as to be separated from the first transport roller 66 by an amount equal to or more than this overrun amount, the end of the end film does not exceed the first transport roller 66.

Next, the control unit 90 determines whether or not the second film sensor 71 between the cutter unit 69 and the recording drum 80 detects a film (step S52). When the leading edge of the end film exceeds the position of the second film sensor 71, the second film sensor 71 detects the film in step S52. In this case, the process proceeds to step S53, the rotation of the carry motor 662 in the forward direction is started, and the first clutch 661 and the second clutch 751 are engaged. As a result, the terminal film is conveyed toward the recording drum 80. Then, such a transportation state is continued for a predetermined time set in the first timer provided in the controller 90 in advance (step S55). The time set in the first timer is set so that the trailing edge of the terminating film enters the lower open portion of the third film guide 78. As a result, the trailing edge of the terminating film is suspended from the slope 73 to the terminating film collecting box 74. Then, the transport motor 662 is stopped and the first clutch 661 is disengaged (step S57). The second clutch 751 remains connected. Then, the carry motor 662 is rotated in the reverse direction (step S58), and the terminal film is carried by the second carry roller 75 for a predetermined time set in the third timer provided in the controller 90 in advance (step S59). The predetermined time set in the third timer is such that the front end of the end film (the end on the recording drum side) exceeds the second transport roller 75, and the end film falls from the slope 73 toward the end film collection box 74. Set to the value. After the elapse of the predetermined time set in the third timer, the control unit 90 stops the carry motor 662 and also disconnects the second clutch 75 1 (step S60). Thereby, the operator can collect the end film from the end film collection box 74 at the same time when the film magazine 62 is replaced.

If the conveying motor 662 is stopped in step S51 and the end film is stopped after some overrun, and the end of the end film has not yet reached the second film sensor 71, in step S52. The second film sensor 71 does not detect a film. In this case, the process proceeds to step S54, and the controller 90 rotates the carry motor 662 in the forward direction to connect the first clutch 661 and the second clutch 751 as in the case of step S53. As a result, the terminal film is conveyed toward the recording drum 80. This conveyance is performed for the time set in the second timer provided in the control unit 90 in advance (step S56), and then the process proceeds to step S57, the conveyance motor 662 is stopped, and the first clutch 661 is disengaged. (Step S57). Here, the set time of the second timer is set to a value longer than the set time of the first timer. This is because in the present case, the length of the end film is shorter than that in the case of proceeding from step S52 to step S53 (in this case, the end of the end film is beyond the second film sensor 71). By the transport by the first transport roller 66 during the second timer setting time, the terminal film is caught by the second transport roller 75, or, if it is shorter than that, the end of the third film guide 78. From the opening on the lower side, it travels down the slope 73 and falls into the terminal film recovery box 74.

In any case, thereafter, as in the above case, the carry motor 662 is rotated in the reverse direction for the time set in the third timer (steps S58, S59). As a result, when the end film is caught in the second conveying roller 75, the end film is conveyed from the slope 73 to the end film collecting box 74 by the second conveying roller 75.

As described above, also in the plate-making output apparatus of this embodiment, the end film does not enter the normal exposed film discharge route, and there is no fear of jam. Further, since the terminal film can be collected separately from the exposed film, the exposed film can be easily handled. Also in the second embodiment described above, the first and second film sensors 70 and 71 act as the material length detecting means, and the control unit 90 that performs the process of step S58 acts as the end processing means.

[Effect of device]

 In the image recording apparatus according to the present invention, when the continuous recording material supplied from the material supply unit is the last portion and the length thereof does not reach the predetermined length, the conveyance roller for conveying the continuous material is used. Rotate in the opposite direction. As a result, the continuous material at the trailing end is returned to the material supply section and does not enter the discharge route of the recording material normally recorded in the image recording section, so that there is no jam in the discharge route. Also, it is possible to prevent abnormal unexposed film from being mixed into normally exposed film.

Further, when the image recording unit uses a drum and means for fixing the recording material to the drum is provided, the drum functions to convey the recording material. In the present invention, in this case, when it is detected that the recording material does not reach the predetermined length, the drum is rotated in the reverse direction and the recording material is also unfixed. As a result, as in the above case, the continuous material at the end portion is returned to the material supply section and does not enter the discharge route of the recording material normally recorded in the image recording section. In addition, the abnormal unexposed film is prevented from being mixed into the normally exposed film.
