Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a photosensitive material magazine used in an image forming apparatus that forms images using photosensitive film, photosensitive paper, or the like.

[Prior Art] For example, a sheet film packaging body in which a plurality of sheet films are laminated is loaded into a printer device, and the end of the cover member of the sheet film packaging body comes out of the printer device. A film magazine device has been proposed in which a sheet film is manually pulled and peeled to open the film, and a sheet film is fed through the opening using a vacuum method. (Refer to Japanese Unexamined Patent Publication No. 63-11936) [Problems to be Solved by the Invention] In the above method, - once the light-shielding cover member is removed, the cover member is reattached to the sheet film package. It cannot be covered or pasted to block light, making it virtually impossible, for example, if you want to immediately change to a film of a different size and print.

In such a case, it is necessary to remove the magazine from the printer or the like and refill the film in a dark room.

This invention has been made in view of the above-mentioned problems.The light-shielding cover of the magazine can be repeatedly peeled off and pasted inside the printer, thereby making it possible to repeatedly open and shield light, and making the magazine disposable. It is an object of the present invention to provide a photosensitive material magazine for a printer, etc., which can save the trouble of changing films by doing so.

[Means for Solving the Problems] In the present invention, in a magazine for a printer or the like that uses a photosensitive material, the magazine body whose upper surface is covered with a flexible light-shielding cover is a housing made of a light-shielding material. A flange extending in all directions is formed on the top surface of the magazine body, and an adhesive layer is provided on this flange. This photosensitive material magazine is characterized in that it is weaker to adhere to the photosensitive material cover, and is formed so that the light-shielding cover can be repeatedly adhered thereon.

[Function] Therefore, the magazine is configured to be completely shielded from light, and can be repeatedly opened and shielded from light, making it extremely easy to replace films and the like.

A double-sided adhesive tape with release paper or an adhesive layer 19 for fixing the magazine body 14 is provided parallel to the front surface of the magazine body 14.

Next, a printer using the photosensitive material magazine 10 formed in this manner will be described.

FIG. 5 is a side view of the printer main body 21, in which a drawer opening/closing rail 30 is fixed to the center of the printer main body 21, and a magazine case 13 attached to a drawer base plate 33 that is engaged with the drawer opening/closing rail 30 is attached to the drawer base plate 33. It is formed so that it can be pulled out to the outside of 21 (to the right in the figure) to load and take out the magazine 10. A lock arm 36 for locking the drawer operated by a solenoid 34 and a switch 31 for detecting drawer opening/closing are provided at the base end of the drawer opening/closing rail 30.
The tip of the locking part 3 provided at the bottom of the drawer base plate 33
It is formed so as to engage and lock with 3a. Further, a barcode reading photosensor 32 and a barcode reading timing switch 40 are provided on the upper side of the drawer opening/closing rail 30 on the right side of the printer main body 21.

Now, when the magazine drawer button (not shown) is pressed, if the magazine 10 is not shielded from light by the magazine cover 18, the winding plate 25 (described later) is moved to the initial position detected by the initial position detection switch 24. After blocking the light, temporarily lock solenoid 3.
4 is turned on to disengage the lock claw engaging part 33a provided at the bottom of the drawer base plate 33 and the lock arm 36,
When the unit push-out spring 35 provided at the left end of the printer main body 21 is extended, the drawer 33 is pushed out to the right side, pulled out, and becomes ready. The drawer exterior portion 33b is integrally formed with the drawer base plate 33.
When the drawer is pulled out by hand, the drawer is fully opened and the magazine case 13 is completely exposed to the outside of the printer body 21.

This state is shown in FIG. 6. In FIG. 6, the exterior of the drawer is omitted for the sake of complication.

Winding units are formed on both sides of the magazine case 13 on the drawer base plate 33 for winding up and rewinding the magazine cover 18 on the magazine 10 loaded in the magazine case 13 one time. This winding unit straddles the magazine case 13 and uses the top surface of the winding roller 22, which rotates and moves in parallel to wind up and unwind the magazine cover 18 of the magazine IO, to rotate to the left and right winding plates 25. The mounting plate 25
It is configured to be rotated via a gear group 28 by a winding motor 29 attached to the winding motor 29 . A pinion 28a is provided on the gear group 28 to open the magazine cover 18 in parallel, and a rack 27 that meshes with the pinion 28a is provided on the side of the winding unit. A slide rail 26 is provided between the case 13 and the winding plate 25 to support the winding plate 25 in a slidable manner.

The magazine case 13 on which the magazine 10 is mounted is provided with a hole 13a on the front side of the bottom through which a lifting rod of a lifting device to be described later passes.
A hole 13b for detecting the barcode 37 of the magazine IO is provided on the back side. Also, around this magazine case 13, there is a micro switch 24 for detecting the initial position of the winding plate 26. Reflective photosensor 23 for detecting the end position. Safety switch for door opening/closing detection to confirm that the drawer is closed 31. A photosensor 32 for reading a bar code for detecting the type of film and a microswitch 4° for timing the photosensor 32 to emit light are provided.

In FIG. 6, the winding plate 25 is loaded with a magazine.

The initial state at the time of removal is shown.The magazine 10 is set in the magazine case 13, and the release paper of the double-sided adhesive tape 19 with release paper attached to the tip of the leader part 18a of the magazine cover 18 is peeled off and rolled up. Loading of the magazine 10 is completed by pasting and winding it around the roller 22.

Next, when a part of the drawer is pushed into the printer main body 21 and stored, the sensor 32 reads the barcode 37 attached to the back of the magazine 10, detects the type and size of the film inside the magazine, and the drawer is activated by a safety switch. 31 is turned on and stored in the printer body 21.

FIG. 7 shows a state in which the magazine cover 18 is peeled off and opened after the drawer is housed in the printer main body 21. Note that the exterior of the drawer is omitted in this figure to avoid complication. The above safety switch 31
is turned on, the take-up motor 29 is turned on, the gear group 28 rotates and the take-up roller 22 is rotated, the take-up plate 25 is moved parallel to the back side, and the magazine cover 18 is moved around the take-up roller. 22 and opened.

Then, the magazine cover 18 is wound up by an amount sufficient to feed the film (about 1/2 in this case), and the hole 14b of the reflective photosensor is opened.

13c is opened and the reflective photosensor 23 is turned off, thereby stopping the winding motor 29. That is, when the magazine cover 18 is present, the light returns to the photo sensor 23 and turns on, but when the magazine cover 18 is wound up, the photo sensor 23 is exposed to the hole 14C1 provided in the flange 14a of the magazine body and the corresponding magazine case 13. It is turned off when the hole 13c provided in the hole 13c is no longer blocked and becomes open, allowing light to pass through.

The relationship between the moving speed of the winding plate 25 and the circumferential speed of the winding roller 22 for opening the magazine cover 18 that blocks light from the magazine body 14 is the moving speed of the winding plate 25, that is, the sliding movement of the winding roller 22. The speed is set to be approximately 1.15 times faster than the circumferential speed of the take-up roller 22.

This is necessary for the winding plate 25 to cover the magazine cover 18 in order to attach it without a gap between the magazine cover 18 and the magazine body 14 when closing the magazine cover 18 while winding it back to block light in order to take out the magazine 10. At the initial stage of winding, the magazine cover 18 is slightly loosened, but as the magazine cover 18 is wound around the winding roller 22, the winding roller 22 becomes loose. As the winding diameter gradually increases and the circumferential speed of the take-up roller 22 also increases accordingly, the slack in the magazine cover 18 disappears. Since the double-sided adhesive tape 20 has a strong adhesion force so that it always adheres to the flange 14a side of the magazine body 14, the winding and unwinding of the magazine cover 18 are smoothly performed.

Next, FIG. 8 is a sectional view showing a part of the drawer and a lifting mechanism, which is a film pushing-up mechanism, which is attached to the printer main body 21. As shown in FIG. This is configured so that the height of the film 7 is always kept constant in order to feed the topmost sheet of the film 7 of the magazine cover to the sub-operation section Di by the conveyance roller 15. (See FIG. 4) For this reason, a lifting mechanism is provided for raising and lowering the lifting rod 5 that lifts the front end side of the cardboard board 6, which is the bottom plate on which the film 7 is laminated inside the magazine body 14. This lifting mechanism has a case in which a nut 4 with a female thread is fixed to the center of a lifting rod mounting plate 39 to which the lifting rods 5 (four in the figure) are attached, and the nut 4 is fixed to the printer main body 21. A feed screw shaft 3, which is attached to the base m21a so as to be vertically rotatable, is engaged with the base m21a through a bearing 11, and is configured to be able to move upward and downward along a lifting guide 16. The gear 2' attached to the lower end of the feed screw shaft 3 meshes with the gear 2 attached to the output shaft of the lifting motor l attached to the case base plate 21a to move the feed screw shaft 3 upward and downward. In addition, this lifting mechanism includes a detection switch 12 on the board 21a that detects the lower limit lifting position, and a handling guide plate 5.
A film height detection member is rotatably supported on a fulcrum 8a at the upper part of the film, and one end is in contact with the upper surface of the film and the other end is bent to face a photo sensor 9 for film height detection. 8 is provided.

Therefore, the state where the lifting rod mounting plate 39 is kicking the photosensor 12 is the initial position, and the top position is detected when the lifting rod 5 comes into contact with the cart position and the bottom of the film 7 due to the rotation of the lifting motor l. When the uppermost film touches the hemispherical end of the detection member 8, the other end turns on the film height detection sensor 9, and the lifting motor l is reversely rotated from this point, producing a certain pulse. It is designed to stop after a few turns.

Although the film height detection member 8 is biased by its own weight in the clockwise direction in FIG. 8 about the fulcrum 8a, the position shown in FIG. 8 is the limit position of movement in the clockwise direction.
As described above, when the lifting motor 1 is rotated in reverse and stopped, the hemispherical end of the detection member 8 is prevented from coming into contact with the upper surface of the film.

When one sheet of film is printed and the film is ejected, the lifting motor 1 rotates to feed the film 7 located at the top of the magazine body 14, and pushes one sheet of film 7. The feed roller 15 and the film 7 are positioned such that the distance between the feed roller 15 and the film 7 is always kept constant.

The film feeding roller 15 is shown in FIGS. 9(A) and 9(B).
As shown in the figure, the roller 15a for the large-sized film 7a and the roller 15b for the small-sized film 7b are half-moon rollers formed in a D-shape, and two of each are attached to the feeding shaft 46 to feed the film. During feeding, as shown in FIG. 11, the structure is such that it contacts the upper surfaces of both ends of the films 7a and 7b of each size to ensure that only the top one is fed. This is because, unlike the paper used in general copying machines, the surface of the film is provided with an emulsion surface, which is a photoreceptor, and the purpose is to prevent scratches on that surface as much as possible. And, it is configured so that it comes into contact only when feeding is performed.

As shown in FIG. 9(A), when the film 7 is a small-sized film cassette lO', the amount by which the lifting motor 1 is reversely rotated from the top is reduced;
As shown in B), in the case of a film cassette 10 containing a large-sized film 7a, the distance between the feeding roller 15a and the film 78 is increased so that the height thereof is kept constant.

Next, FIG. 10 shows a perspective view showing the structure of the film feeding device. This feeding device has two feeding rollers 15a for large size film 7 and two feeding rollers 15b for small size film 7. The feeding shaft 46 is attached to both ends of a feeding shaft 46, and the feeding shaft 46 is attached to the center of the tip side of a swinging plate 51 provided parallel to the upper part of the swinging plate 51 so as to swing together with the swinging sorting guide plate 50. A gear 53 of a feed shaft drive shaft 47 provided parallel to the feed shaft 46 and a gear 54 of the feed shaft 46 mesh with each other, and are rotationally driven by the feed motor 44. It is formed to do so. On the other hand, a feeding guide plate moving shaft 48 is provided on the base end side of the rocking plate 51 in parallel with the feeding shaft 46, and this shaft 48 has a feeding guide plate 50 having a bent portion at its tip. And a rocking plate 51 is swingably attached. A feeding guide moving motor 43 is connected to the feeding guide plate moving shaft 48 so as to swing the feeding guide plate. Further, a rotation detection plate 55 is attached to the feed shaft 46, and a micro switch 45 for detecting the paper feed roller is provided correspondingly thereto. A guide plate upper position detection sensor 42 and a guide plate lower position detection sensor 41 are provided at upper and lower positions corresponding to the upper and lower positions.

The feeding rollers 15a and 15b are shown in FIGS. 12(A) and 12(B).
) is a half-moon roller formed in a 0 shape,
In response to the position detection of the feeding roller detection microswitch 45, the D-cut surface is normally stopped in a state facing the film surface, as shown in FIG. Also, both have a circumference of 2, 2'
are formed so that they are equal. This is because once the film 7 is fed out the distance to the conveyance roller 56 provided in the printer main body 21 shown in FIG. be.

Further, as shown in FIG. 10, feeding rollers 15a, 15
b is rotated once by the feed motor 44 to feed the topmost film of the stacked films 7, and the rotation of the feed rollers 15a and 15b is controlled by a notch in the rotation detection plate 55. Detection is performed by turning on the detection microswitch 45, and the entire film feeding mechanism is moved up by the feeding guide moving motor 43 and its shaft 48 so that the feeding guide plate 50 does not get in the way when the drawer is taken in or taken out. It is configured so that it can be moved by swinging downward.

Next, FIG. 13 (A), (B), CD).

The relationship between the feeding guide plate 50 and the magazine 10 will be explained based on (D). As shown in FIG. 13(A), a rib 14b is provided on the front surface of the magazine body 14, while a rib 14b is provided at the tip of the feeding guide plate 50 as shown in FIG. 13(D).
The protruding portion 50b that is fitted with this is formed in a comb-teeth shape, and when the feeding unit descends, it engages with the rib 14b of the magazine body 14 without any gap, and when the film is fed, it is shown in FIG. 13(C). When feeding is performed in the state shown, the leading edge of the film 7 and the feeding guide 50 are formed so as not to collide with each other. Further, FIG. 13(B) shows the state after the film is fed, and the feeding unit is swung to the standby position by turning on the feeding guide moving motor 43.

The operation of the film feeding device of the printer configured as described above will be explained with reference to the flowcharts shown in FIGS. 14 to 22.

FIG. 14 shows the main flowchart, and by pressing the button of the printer's power supply (not shown),
PTJ is powered up.

First, the drawer opening/closing detection switch 31 detects whether or not the film magazine case 13 is pulled out.
Detected by. When the magazine case 13 is pulled out, a display prompting loading of the magazine is displayed on the display panel of the printer body (not shown), and when the magazine is loaded, the status of each device inside the printer is diagnosed ( self-diagnosis), and if there are no errors, initial settings are made and the printer is ready for printing.9 Next, with reference to the flowchart shown in FIG. 15 and FIGS. 5 to 7, loading the magazine 10 and loading the magazine cover 18
The winding process will be explained.

First, it is determined whether the drawer 33 has been pushed in after being pulled out. In order to read the type and size of the film inserted into the magazine using the barcode 37 attached to the rear wall of the magazine main body 14, this barcode reading timing is used to first make the barcode reading photosensor 32 emit light. The judgment is made by checking whether the switch 40 changes from off to on. Then, the barcode 37 affixed 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 that winds up the magazine cover 18 is rotated in the normal direction, and a timer is started. The set value of this timer is set a little more than the value required for the normal winding operation of the magazine cover 18. Even if the winding detection photosensor 32 repeatedly opens the hole 14c of the flange 14a of the magazine body 14 until the magazine cover 18 opens, and the winding mechanism is activated, the winding detection sensor 32 does not detect the completion of winding of the cover 18, it is determined that a winding failure has occurred due to forgetting to fix the magazine cover 18a to the winding roller 22, or that the motor is malfunctioning, and the winding motor 29 is immediately turned off. The winding motor 29 is stopped and an error message is displayed on the display panel.When there are no abnormalities and the magazine cover 18 is normally wound, 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 explained with reference to the flowchart shown in FIGS. 16(A) and CB) and FIG. 8. First, the lifting lower limit position detection switch 12 detects whether the film 7 is set at the initial position. If the lifting mounting plate 39 is not in this position, the lifting motor 1 is reversed and a timer is started. Then, when the time is up, the lifting motor 1 is stopped. If there is a problem with the lifting device, an error message will be displayed.Next, the lifting motor is moved so that the uppermost film of the film 7 inserted into the cassette body 14 is located at the initial position where it contacts the feeding rollers 15a and 15b. 1 is rotated in the normal direction to raise the lifting rod 5, and with the uppermost film 7 in contact with the film height detection member 8, the photo sensor 9 for film height detection is activated, and the lifting motor 1 is stopped.

Next, moving to the flowchart shown in FIG. 16(B), the barcode reading sensor 32 detects information such as the film type and size that has been read in advance on the barcode 37 pasted on the cassette 10, and cassette size,
Judging small. Then, the lifting motor 1 is reversed and the pulse counter is started, and the preset number of pulses (mn) is set according to the size of the film cassette.
(m<n), the lifting motor 1 stops reversing, and the uppermost film inserted into the cassette body 14 does not come into contact with the film height detection member 8, and each feeding roller 15a.

Figure 9 (A) where the D cup 8 of 15b is located and does not make contact.
, the state shown in (B) is reached. And the magazine body 14
A photo sensor 9 for detecting film height detects whether there is a film 7 in the magazine 7 or not, and if there is no film, an error message is displayed and the setting of the magazine 10 is completed.

Next, the operation of the feeding device will be explained with reference to the flowchart shown in FIG. 17 and FIG. 1O. The upper position sensor 42 shown in FIG. 1O first detects whether the feed roller 15a or 15b is in the upper position. When the swinging plate 51 and the feeding guide plate 50 are not in the upper position, the feeding guide moving motor 43 is reversed and a timer is started, and the swinging plate 51 and the feeding guide plate 50 are swung. Move the feeding rollers 15a and 15b upward. At this time, the time value of the timer is normally set to be slightly longer than the time required to move the paper feed mechanism from the lower position to the upper position. When the upper position sensor 42 detects that the feed roller 15a or 15b has reached the upper position, the feed guide moving motor 43 stops rotating in reverse. If the completion of reaching the upper position is not detected by the time the timer times up, it is determined that there is a problem with the feeding mechanism, and the motor 43 is immediately stopped and an error message is displayed.

After checking the swing of the feeding mechanism in this way, the feeding motor 44 is turned on and the feeding roller 15a or 15b is rotated.
and start the timer. The time value of the timer at this time is normally set to be slightly longer than the time required for one rotation of the feeding roller 15a or 15b.

Then, moving to the flowchart shown in FIG. 17(B),
Whether the feed roller 15a or 15b has reached the initial position is detected by the feed roller detection microswitch 45 based on the rotation of the rotation detection plate 40 of the feed shaft 46.

At this time, if the completion of reaching the initial position is not detected by the time the above-mentioned timer times up, it is determined that there is a problem with the drive of the feed roller, and the feed motor 4 is immediately activated.
4 and displays an error message.On the other hand, if the initial position is reached before the timer times out,
At that point, the feed motor 44 is stopped.

Next, the feeding guide moving motor 43 is rotated in the normal direction to rotate the feeding mechanism downward and a timer is started. Then, when detected by the lower position sensor 41,
The feed roller 15a or 15b is in the lower position, and the normal rotation of the feed guide moving motor 43 is stopped. At this time, if the feeding mechanism does not reach the lower position by the time the timer times up, it is determined that there is a problem with the feeding mechanism, and the feeding guide moving motor 43 is immediately moved.
In this way, the feeding mechanism is ready for operation.

Next, with reference to the flowchart shown in FIG. 18 and FIGS. 1 and 8, the operation after printing is started will be explained. 6. Printing is started when a print button (not shown) is pressed or a signal is input via communication. . An image is drawn on the film above the sub-scanning section by a laser beam modulated by the optical recording device A. When the image formation is completed, the photo sensor 9 for detecting film height detects whether or not there is any film left in the magazine 10, and if there is no film, a message indicating that there is no film is displayed.

If the film is present, the lifting motor 1 is rotated forward and the pulse counter is started. When the preset number of pulses t corresponding to the thickness of one film is reached, normal rotation of the lifting motor 1 is stopped and the topmost part of the film 7 inserted into the magazine body 14 is fed. , the preparation for the next print is completed.

Next, the magazine ejecting operation will be described with reference to the flowchart shown in FIG. 19 and FIGS. 5 to 7.

When removing the magazine 10 from the printer device, first press the magazine eject button (not shown), and the magazine cover 1 will be removed.
The take-up motor 29 is reversed so that the take-up roller 22 of No. 8 is rotated in the rewinding direction, and a timer is started. The set value of this timer is set to be slightly longer than the time required for normal rewinding operation. Then, the take-up roller 22 is activated by the take-up limit switch 24.
Detect whether the has been rewound to the initial position. At this time, the conditions are that the winding photosensor 23 is always turned off and the magazine cover 18 shields the cassette body 14 from light. If the magazine cover 18 does not cover the hole 14c of the flange 14a of the cassette body even after the timer has expired, it is determined that a light blocking problem has occurred, and the inspection motor 22 is immediately stopped and an error occurs. Perform display.

When the take-up limit switch 24 detects the initial position of the take-up roller 22, it stops the reverse rotation of the take-up motor 22, turns on the lock solenoid 34, releases the drawer lock, and pulls out the drawer to take out the magazine 10. becomes possible.

The flowchart shown in FIG. 20 shows a routine that always performs a check at certain intervals, in addition to the routine based on the main flowchart shown in FIG. That is, it detects whether the magazine IO can be taken out from the printer main body 21. When a magazine load button (not shown) is pressed, it detects whether printing has finished, and if printing has finished, the magazine can be taken out. becomes.

[Effects of the Invention] As explained above, the magazine of the present invention has a light-shielding magazine cover that can be repeatedly attached to or peeled off from the magazine body, so it can be easily replaced with a light-shielded magazine even in a bright place. can do. Furthermore, since the magazine is disposable, there is no need to refill the film or photosensitive paper in the darkroom. Furthermore, it can be easily installed in a printer, and after installation, the magazine cover can be peeled off to prepare for printing.
