Since the sticking force is strengthened so as to be attached to the side of the collar 14a of the 14, the magazine cover 18 is smoothly wound and unwound.

Next, FIG. 8 is a cross-sectional view showing a drawer portion and a lifting mechanism which is a film lifting mechanism attached to the printer main body 21. In this configuration, the uppermost sheet of the film 7 in the magazine 10 is fed to the sub-operation unit D by the transport roller 15, so that the height of the film 7 is always kept constant. (See FIG. 4.) For this purpose, a lifting mechanism is provided for lifting and lowering a lifting rod 5 for lifting the front end side of a card board 6 which is a bottom plate on which the film 7 in the magazine body 14 is laminated. In this lifting mechanism, a nut 4 having a female thread is fixed at the center of a lifting rod mounting plate 39 to which the lifting rods 5 (four in the figure) are mounted, and the nut 4 is fixed to the printer body 21. The feed screw shaft 3 attached to the substrate 21a via the bearing 11 so as to be vertically rotatable is engaged, and is configured to be able to move up and down along the lifting guide 16. Then, the gear 2 'attached to the lower end of the feed screw shaft 3 and the gear 2 attached to the output shaft of the lifting motor 1 attached to the case board 21a mesh and move up and down. The lifting mechanism includes a detection switch 12 for detecting a lifting lower limit position on the substrate 21a, and a rotatable fulcrum 8a at an upper portion of the discarding guide plate 50. Is provided so as to be opposed to the photo sensor 9 for detecting the film height.

Therefore, the state where the lifting rod mounting plate 39 is illuminating the photosensor 12 is the initial position. The top position is detected by the rotation of the lifting motor 1 so that the lifting rod 5 comes into contact with the card board 6 and the leading end of the film 7 is moved. When the film is lifted up and the uppermost film cuts off the hemispherical end of the detecting member 8, the other end turns on the film height detecting sensor 9, and the lifting motor 1 is rotated in reverse from this point, and the pulse number is increased. It is configured to stop when rotated. The film height detecting member 8 is biased by its own weight in the clockwise direction in FIG. 8 around the fulcrum 8a, but the position shown in FIG. 8 is the movement limit position in the clockwise direction, As described above, when the lifting motor 1 is rotated in the reverse direction and stopped, the hemispherical end of the detection member 8 does not contact the upper surface of the film.

When one sheet is printed and the film is discharged, the lifting motor 1 is rotated to feed the film 7 located at the uppermost position in the magazine body 14, and one sheet of the film 7 is pushed. And the film 7 is always positioned so that the distance between the feed roller 15 and the film 7 is kept constant.

The rollers 15 for feeding the film are shown in FIGS. 9 (A) and 9 (B).
The roller 15a for the large-size film 7a and the roller 15b for the small-size film 7b are half-moon rollers formed in a D-shape as shown in FIG.
When the film is fed, as shown in FIG. 11, it is configured to contact the upper surfaces of both ends of the films 7a and 7b of the respective sizes and to reliably send out only the uppermost one. This is because, unlike the case of paper, as in a general copying machine, an emulsion surface which is a photoreceptor is provided on the surface of the film so as not to damage the surface as much as possible. And it is comprised so that it may contact only at the time of feeding.

As shown in FIG. 9 (A), when the film 7 is a small-sized film cassette 10 ', the amount of reverse rotation of the lifting motor 1 from the top is reduced, and as shown in FIG. 9 (B). In the case of the film cassette 10 of the large-sized film 7a, the height is kept constant so that the distance between the feeding roller 15a and the film 7a is increased.

Next, FIG. 10 is a perspective view showing a configuration of a film feeding device portion. In this feeding device, two feeding rollers 15a for the large size and two feeding rollers 15b for the small size of the film 7 are respectively attached to both ends of the feeding shaft 46, and the feeding shaft 46 swings. Swinging plate 51 provided in parallel with the upper part so as to swing together with the separating card plate 50
The gear 53 of the feed shaft drive shaft 47 and the gear 54 of the feed shaft 46, which are supported by a support plate 52 provided at the center on the tip side of the feed shaft 46 and provided in parallel with the feed shaft 46, motor
It is formed to be driven to rotate by 44. On the other hand, a feed guide plate moving shaft 48 is provided on the base end side of the swing plate 51 in parallel with the feed shaft 46.
A feeding guide plate 50 having a bent portion at the tip and a swinging plate 51 are swingably attached to 48. A feed guide moving motor 43 is connected to the feed guide plate moving shaft 48 so as to swing. A rotation detection plate 55 is attached to the feed shaft 46, and a paper feed roller detection microswitch 45 is provided corresponding to the rotation detection plate 55, and a detection plate 51a is provided on the upper surface of the swing plate 51. A guide plate upper position detecting sensor 42 and a guide plate lower position detecting sensor 41 are provided at the upper and lower positions corresponding to the mounted state.

The feed rollers 15a and 15b are half-moon rollers formed in a D-shape as shown in FIGS. 12 (A) and 12 (B), and are normally operated in accordance with the position detection of the feed roller detecting microswitch 45. As shown in FIG. 8, the D-cut is stopped with the cut surface facing the film surface. In addition, both are formed so that their perimeters l and l 'are equal. This is because if the film 7 is sent out to the transport roller 56 provided in the printer main body 21 shown in FIG. 4, the film 7 is transferred to the sub-scanning section D of the printer by the transport roller 56. is there.

As shown in FIG. 10, the feed rollers 15a and 15b feed the uppermost film of the loaded film 7 by one rotation of the feed motor 44. The feed rollers 15a and 15b
The rotation control is performed by opening the feed roller detection microswitch 45 at the notch of the rotation detection plate 55. Further, when the drawer is taken in and out, the whole film feeding mechanism can be moved up and down by the feeding guide moving motor 43 and its shaft 48 so that the feeding guide plate 50 does not become an obstacle. Have been.

Next, the relationship between the feed guide plate 50 and the magazine 10 will be described based on FIGS. 13 (A), (B), (D) and (D). No.
A rib 14b is provided on the front surface of the magazine body 14 as shown in FIG. 13 (A), while it is fitted to the leading end of the feed guide plate 50 as shown in FIG. 13 (D). When the feeding unit descends, the projecting portion 50b is engaged with the rib 14b of the magazine body 14 without any gap, and the film is fed by the body shown in FIG. The film is fed so that the leading end of the film 7 does not collide with the feeding guide 50. FIG. 13B shows a state after the film is fed, and the feeding unit swings by turning on the feeding guide moving mode 43 to be in the standby position.

The operation of the film feeding device of the printer configured as described above will be described with reference to the flowcharts shown in FIGS.

FIG. 14 shows a main flowchart, in which the CP of the control device is pressed by pressing a button of a power supply device of a printer (not shown).
U is powered up.

Then, first, the drawer open / close detection switch 31 detects whether or not the film magazine case 13 is pulled out. When the magazine case 13 is in the state of being pulled out, a display for urging the user to load a magazine is displayed on a display panel of the printer body (not shown). When the magazine is loaded, the status of each device in the printer is diagnosed (self-diagnosis). If there is no error, the printer is initialized and the printer is ready for printing.

Next, the loading of the magazine 10 and the winding of the magazine cover 18 will be described with reference to the flowchart shown in FIG. 15 and FIGS. 5 to 7.

First, it is determined whether the drawer 33 has been pulled out and then pushed in. This is because the bar code 37 attached to the rear wall of the magazine body 14 reads the type and size of the film inserted into the magazine. It is determined whether the switch 40 has changed from off to on. Then, the barcode 37 attached to the magazine is read by the barcode reading photosensor 32, and the type and size of the film in the magazine are sent to the CPU of the control device (not shown).

Next, it is determined by the winding plate limit switch 24 whether the magazine cover 18 is at the initial position. Then, if it is at the initial position, the winding motor 29 for winding the magazine cover 18 is rotated forward and the timer is started. The set value of this timer is set slightly more than the value required for the normal winding operation for winding the magazine cover 18. Then, the winding detection photosensor 32 repeats the hole 14c of the flange 14a of the magazine body 14 until the magazine cover 18 is opened, and even if the winding mechanism is operated, the winding detection is performed by the time-up of the timer. If the sensor 32 does not detect that the take-up of the cover 18 is completed, the magazine cover 18a may fail to be fixed to the take-up roller 22, for example, or a take-up failure may occur. Is stopped and an error message is displayed on the display panel. When the magazine cover 18 is normally wound without these abnormalities, the winding motor 29 is stopped. This state is the state shown in FIG.

Next, the operation of the film magazine lifting device will be described with reference to the flowcharts shown in FIGS. 16 (A) and (B) and FIG. First, whether the film 7 is set to the initial position is detected by the lifting lower limit position detecting switch 12. If the lifting mounting plate 39 is not at this position, the lifting motor 1 is rotated in the reverse direction and the timer is started. When the time is up, the lifting motor 1 is stopped. If there is a problem with the lifting device, an error is displayed.
Next, the lifting motor 1 is rotated forward so that the uppermost film of the film 7 inserted into the cassette body 14 comes into contact with the feeding rollers 15a and 15b, and the lifting rod 5 is raised. Height detection member 8
Then, the photo sensor 9 for detecting the film height is operated in a state where the uppermost film 7 is in contact with the film 7, and the lifting motor 1 is stopped.

Next, the process proceeds to the flowchart shown in FIG. 16 (B), in which the bar code 37 attached to the cassette 10 detects information such as the film type and size previously read by the bar code reading sensor 32. Judge the size of the cassette. Then, the lifting motor 1 is rotated in the reverse direction and the pulse counter is started, and the number of pulses m, n (m <n) set in advance according to the size of the film cassette is small.
n), the reverse rotation of the lifting motor 1 is stopped, the uppermost film inserted into the cassette body 14 does not contact the film height detecting member 8, and the D of the feed rollers 15a and 15b The state shown in FIGS. 9A and 9B does not come into contact with the cut portion. The film height detecting photosensor 9 detects whether or not the film 7 is present in the magazine main body 14. If there is no film, an error is displayed, and the setting of the magazine 10 is completed.

Next, the operation of the feeding device will be described with reference to the flowchart shown in FIG. 17 and FIG. The upper position sensor 42 shown in FIG. 10 first detects whether the feed roller 15a or 15b is at the upper position. When the swing plate 51 and the feed guide plate 50 are not at the upper position, the feed guide moving motor 43 is reversely rotated and a timer is started,
The swinging plate 51 and the feeding guide plate 50 are once swung to move the feeding rollers 15a and 15b upward. At this time, the time value of the timer is set slightly longer than the time required for moving the paper feed mechanism from the lower position to the upper position.
Then, when the upper position sensor 42 detects that the feed roller 15a or 15b has reached the upper position,
The reverse rotation of the feed guide moving motor 43 is stopped. If the completion of reaching the upper position is not detected by the time-up of the timer, it is determined that a problem has occurred in the feeding mechanism, the motor 43 is immediately stopped, and an error is displayed.

After checking the swing of the feeding mechanism, the feeding motor 44 is turned on to rotate the feeding roller 15a or 15b and start the timer. At this time, the time value of the timer is set slightly more than the time required for the normal rotation of the feed roller 15a or 15b.

Then, the process proceeds to the flowchart shown in FIG.
Whether the feed roller 15a or 15b has reached the initial position is detected by rotation of the rotation detection plate 40 of the feed shaft 46 by the feed roller detecting microswitch 45.

At this time, if the completion of reaching the initial position is not detected by the time-up of the timer, it is determined that there is a problem in the driving of the feeding roller, and the feeding motor is immediately determined.
Stops 44 and displays an error. On the other hand, if it reaches the initial position by the time up of the timer,
At that time, the feed motor 44 is stopped.

Next, the feed guide moving motor 43 is rotated forward to rotate the feed mechanism downward and start the timer. Then, when detected by the lower position sensor 41, the feed roller 15a or 15b is in the lower position,
The forward rotation of the feed guide moving motor 43 is stopped. At this time, if the feeding mechanism does not come to the lower position by the time-up of the timer, it is determined that a problem has occurred in the feeding mechanism, the feed guide moving motor 43 is immediately stopped, and an error is displayed. Do. Thus, the feeding mechanism is in an operable state.

Next, the operation after the start of printing will be described with reference to the flowchart shown in FIG. 18 and FIGS. 1 and 8. A print button (not shown) is pressed or a signal is input by communication to start printing. An image is drawn on the film on the sub-scanning portion D by the laser beam modulated by the optical recording device A. When the image formation is completed, it is detected by the film height detecting photosensor 9 whether or not the film remains in the magazine 10, and when there is no film, an indication of no film is displayed. If the film is loaded, the lifting motor 1 is rotated forward and the pulse counter is started. Then, when the number of pulses t corresponding to the preset thickness of one film is reached,
Stop the forward rotation of the lifting motor 1
The uppermost portion of the film 7 inserted into the position 14 is fed, and preparation for the next print is completed.

Next, the operation of taking out the magazine will be described with reference to the flowchart shown in FIG. 19 and FIGS. 5 to 7.
When the magazine 10 is taken out of the printer device, when a magazine removal button (not shown) is first pressed, the take-up motor 29 is rotated in the reverse direction so as to rotate the take-up roller 22 of the magazine cover 18 in the rewinding direction, and the timer is started. The set value of this timer is set slightly longer than the time required for the normal rewind operation. Then, the winding limit switch 24 detects whether the winding roller 22 has been rewound to the initial position. At this time, the condition is that the winding photosensor 23 is always turned off and the magazine cover 18 shields the cassette body 14 from light. Even after the timer expires, the magazine cover
If the cover 18 does not cover the hole 14c of the flange 14a of the cassette body, it is determined that a light-blocking trouble has occurred, and the winding motor 22 is immediately stopped and an error is displayed.

When the winding limit switch 24 detects the initial position of the winding roller 22, the reverse rotation of the winding motor 22 is stopped, the lock solenoid 34 is turned on to release the lock of the drawer, and the drawer is pulled out to take out the magazine 10. Becomes possible.

The flowchart shown in FIG. 20 shows a routine in which a check is always performed at a certain period apart from the routine based on the main flowchart shown in FIG. That is, it detects whether the magazine 10 can be removed from the printer main body 21.When a magazine load button (not shown) is pressed, it is detected whether printing is completed,
If the printing is completed, the magazine can be taken out.

[Effects of the Invention] As is clear from the above description, according to the present invention, the light-shielding sheet cover is repeatedly provided on the flange portion of the magazine main body so that the light-shielding sheet cover can be stuck or peeled off. Can be easily replaced. Further, since the magazine is disposable, it is not necessary to refill the film or the photosensitive paper in a dark room. Further, since the detecting means detects the hole for detecting the peeling and automatically stops the peeling based on the detecting operation of the hole, there is no possibility that the light shielding sheet cover is peeled more than necessary.
