Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photosensitive material magazine containing a roll of photosensitive material having a light-shielding member wound around its outer peripheral portion.

[0002]

2. Description of the Related Art A magazine containing a roll-shaped photosensitive material wound around a core is attached to the main body of the apparatus,
2. Description of the Related Art A printer processor for exposing a photosensitive material while sequentially sending it to the apparatus main body side has been known.

When the photosensitive material is stored in a magazine attached to the printer processor, the reel rotatably supported by the magazine is taken out from the magazine,
The reel was inserted into the core around which the photosensitive material was wound.

When a magazine is attached to the apparatus main body and the photosensitive material is sent out from the magazine or rewound into the magazine, the reel is rotated at an appropriate speed by a drive mechanism provided in advance on the apparatus main body side, The photosensitive material is sent out from the magazine to the apparatus main body side or is rewound from the apparatus main body side to the magazine.

Further, in recent years, in order to make it possible to store a photosensitive material in a magazine in a bright room, a light shielding member covers the peripheral surface and both end surfaces of the photosensitive material wound in a roll on a core. Things became known.

When the light-sensitive material coated with the light-shielding member is stored in the magazine, the apparatus main body is loaded with the magazine, and the exposure processing is performed, first, the light-shielding member is pulled out from the opening of the magazine. The light-shielding member is broken at the peripheral surface and both end surfaces, and the light-sensitive material is pulled out from the opening of the magazine so as to follow the light-shielding member, thereby enabling storage in a bright room.

That is, the light-shielding member covering the peripheral surface of the photosensitive material serves as a leader tape, is pulled out from the magazine, and subsequently, the photosensitive material is conveyed into the main body of the apparatus.

Here, the light shielding member is wound around the entire outer peripheral surface of the rolled photosensitive material in order to shield the photosensitive material from light. Therefore, the light shielding member is usually in the form of a thin sheet, and is formed so as to be slightly wider than the width of the photosensitive material.

[0009]

As described above, in the printer processor, it is necessary that the light shielding member, which is thinner and less rigid than the photosensitive material and wider than the photosensitive material, can be easily pulled out from the opening as the leader tape. Although I have
If the width of the photosensitive material which is connected to the light-shielding member and subsequently sent out is not regulated, the photosensitive material meanders, which may cause paper jam due to meandering.

On the other hand, after the photosensitive material is stored in the magazine, the light-shielding member becomes unnecessary, so that it is necessary to smoothly pull out the light-shielding member from the magazine, but the structure is such that the drawer can be smoothly pulled out. Then, when the magazine is suddenly lifted and the magazine is vibrated, the weight of the photosensitive material may cause the leading end side of the photosensitive material to be drawn into the magazine.

The present invention has been made in consideration of the above facts, and improves workability in storing a roll-shaped photosensitive material having a light-shielding member wound around an outer peripheral portion and transportability of the photosensitive material. The purpose is to obtain a photosensitive material magazine which prevents the photosensitive material from being drawn into the magazine.

[0012]

According to a first aspect of the present invention, there is provided a photosensitive material magazine, wherein a photosensitive material wound in a roll shape and having a light-shielding member attached to its starting end is housed in an outer frame. A magazine for a photosensitive material, which is guided by a guide roller mounted in an outer frame, passes through an opening formed in the outer frame, and is sent out to an apparatus main body side for processing the photosensitive material. A first guide groove for introducing the light shielding member into the opening when the material is stored in the outer frame; and a first guide groove adjacent to the first guide groove and between the guide roller and the opening. A second guide groove that guides the photosensitive material located while making it planar and allows the photosensitive material to pass therethrough.

According to a second aspect of the present invention, a photosensitive material magazine is housed in an outer frame of a photosensitive material which is wound into a roll and has a light-shielding member attached to a starting end thereof. The photosensitive material is attached to the outer frame. A magazine for a photosensitive material which is guided by a guide roller and passes through an opening formed in the outer frame and is sent out to the apparatus main body side for processing the photosensitive material. And a sandwiching roller that can sandwich the light shielding member and that can rotate only in a direction that sends the photosensitive material and the light shielding member to the opening side, and a sandwiching position of the sandwiching roller that supports the sandwiching roller. A support member reciprocally attached to the outer frame so as to move between the support member and the clamp release position, and the support member reciprocates while engaging and engaging the support member Low A first engaging member that moves by an urging force to a clamping release position, a lid that is openably and closably attached to the outer frame and that shields the inside of the outer frame from light in a closed state, and the lid that is attached to the lid and Of the sandwiching roller by contacting the first engaging member in the closed state with respect to the outer frame and moving the first engaging member against the biasing force of the first engaging member. An operating member that moves to a sandwiching position and an operating member that engages with the supporting member and is reciprocally moved by the operating member from the device body side when the outer frame is attached to the device body to reciprocate the sandwiching roller. It has a 2nd engaging member which moves to a pinch release position.

[0014]

The operation according to claim 1 will be described below.

An outer frame houses a photosensitive material wound in a roll shape and having a light-shielding member attached to the starting end thereof. A guide roller mounted in the outer frame guides the photosensitive material, and an opening formed in the outer frame allows the photosensitive material to pass therethrough, and the photosensitive material is sent to the main body of the apparatus. The photosensitive material is processed on the side.

Here, when the photosensitive material is stored in the outer frame, the light-shielding member is introduced into the opening portion side using the first guide groove, and is drawn out following the light-shielding member to form the guide roller and the opening portion. The photosensitive material located between the two is guided while the second guide groove is flat.

Therefore, by guiding the light shielding member as the leader tape to the first guide groove, the light shielding member can be easily sent out from the opening. Further, due to the tension generated when the light shielding member is pulled out from the magazine to the apparatus main body side, the light shielding member is folded into the ears, and the light shielding member is moved from the first guide groove to the first guide groove while the light shielding member is being pulled out. The photosensitive material connected to the second light guide member and guided to the second light guide groove and connected to the light shielding member is also guided to the second light guide groove and sent out. Therefore, even when the width dimension of the light-shielding member and the width of the light-sensitive material drawn out subsequently to the light-shielding member are different from each other, the light-sensitive material can be conveyed without meandering by adjusting the width dimension of the second guide groove to the light-sensitive material. .

The operation according to claim 2 will be described below. Also in this claim, the photosensitive material is sent out to the apparatus main body side as in the first aspect.

However, the sandwiching roller can sandwich the photosensitive material and the light shielding member together with the guide roller, and can rotate only in the direction of sending out the photosensitive material and the light shielding member to the opening side, so that the supporting material sandwiches. The roller is reciprocally attached to the outer frame so as to move the roller between the pinching position and the pinch releasing position.

The first engaging member engages with the supporting member to reciprocate the supporting member to move the pinching roller to the pinching releasing position. On the other hand, in the closed state of the lid with respect to the outer frame, the inside of the outer frame is shielded from light, and the operation member attached to the lid moves to the first position when the lid is closed.
By moving the first engaging member by contacting the engaging member of No. 1, the sandwiching roller is moved to the sandwiching position. Further, the second engaging member is operated from the apparatus main body side with the attachment of the outer frame to the apparatus main body to reciprocate the supporting member and move the sandwiching roller to the sandwiching release position.

Therefore, when the photosensitive material is stored, the sandwiching roller is at the sandwiching release position, the light shielding member can be easily introduced into the opening, and when the lid is closed after storage, the sandwiching roller is at the sandwiching position. The light shielding member can be sandwiched between the sandwiching roller and the guide roller by moving. When the outer frame accommodating the photosensitive material is attached to the apparatus main body, the nip roller moves to the nip release position again, and the photosensitive material can be easily conveyed to the apparatus main body.

As a result, the leading edge of the photosensitive material is not pulled into the magazine even when the magazine is vibrated while the light-shielding member is smoothly pulled out.

When the guide cam 128 is moved to the position shown by the solid line in FIG. 1 in a state where the photographic printing paper 22 is hung between the guide roller 124 and the guide roller pair 126, as shown by the imaginary line in FIG. Roller 12
4, the loop 1 of the photographic printing paper 22 between the guide roller pair 126
34 is formed.

A loop sensor 132 composed of a pair of a light emitting element and a light receiving element is provided below the guide roller 124 and the guide roller pair 126. The photographic printing paper 2 is provided between the guide roller 124 and the guide roller pair 126.
When the guide cam 128 is moved to the position shown by the solid line in FIG. 1 in a state where the two are suspended, the loop of the photographic printing paper 22 is provided between the guide roller 124 and the guide roller pair 126 as shown in FIG. 134 is formed. Loop sensor 132
Is turned on when the loop 134 of the photographic printing paper 22 is larger than a predetermined size. The guide roller pair 126 is rotated by the driving force of the pulse motor M3 being transmitted, and sandwiches the photographic printing paper 22 and sends the photographic printing paper 22 to the processor section 14 side.

Guide roller 124, guide roller pair 12
A passage detection sensor 150 is provided adjacent to the guide roller 124 and the guide roller pair 126 on the downstream side of the six arrangement portions. The passage detection sensor 150 is also composed of a pair of a light emitting element and a light receiving element, and is turned on when the leading end of the photographic printing paper 22 passes a portion where the guide roller pair 126 is disposed.

The processor section 14 is provided with a plurality of processing tanks (not shown), and the processing liquid is stored in each processing tank. The printing paper 22 conveyed to the processor unit 14 is dipped in the processing liquid in each processing tank and processed.

Next, the operation of this embodiment will be described. When the opening / closing lid 18B is opened, as shown in FIG.
And the coil spring 17 via the bracket 152.
2, the attachment / detachment detection pin 34 is retracted, and the light-shielding shutter 3
Move 0 to the retracted position. With the opening / closing lid 18B open, the reel 146 is taken out and fitted into the core 140 of the new paper roll 21. And the photographic paper 22
The paper roll 21 is stored in a predetermined position of the magazine 18 while being covered with the light shielding member 148.

When the storage of the photographic printing paper 22 is completed, the light shielding member 148 on the peripheral surface side is grasped and inserted until the tip of the light shielding member 148 reaches the tip of the paper port 26 beyond the opening 29, as shown in FIG. Thus, the opening / closing lid 18B is closed to bring the opening / closing lid 18B into a closed state with respect to the magazine body 18A. In this closed state, the operation piece 174 has the rotating piece 16
By contacting the lower end portion 164 </ b> A of the No. 4 and rotating the rotating piece 164 about the support shaft 150, the sandwiching roller 156 is moved to the sandwiching position via the rotation of the bracket 152. As a result, the sandwiching roller 156 is replaced by the guide roller 23.
The light blocking member 148 can be sandwiched between and. Further, the photographic paper 22 and the light shielding member 14 are intervened by the free wheel clutch.
8 can be rotated only in the direction of sending 8 to the opening 29 side.

As a result of the attachment / detachment detection pin 34 being pushed back into the magazine 18 in conjunction with the rotation of the bracket 152, the light-shielding shutter 30 in the paper port 26 moves to the light-shielding position, and the opening / closing lid 18B opens the magazine body 18A. As the inside is shielded, the inside of the paper port 26 is shielded while the tip of the shielding member 148 is nipped. Then, after the opening / closing lid 18B is closed, it is locked by the lock mechanism 25.

Next, when the light-shielding member 148 pulled out from the opening 29 is pulled, the light-shielding member 148 is broken on the peripheral surface side and both end surface sides of the printing paper 22 and is welded in advance. It is possible to follow the starting end of 22 and guide it to the opening 29.

When the light shielding member 148 is introduced to the opening 29 side, the opening 2 is inserted through the wide guide groove 202.
By guiding the light-shielding member 9 to 9, the light-shielding member 148 wider than the photographic paper 22 is easily guided to the opening 29. And
After completely pulling out the light blocking member 148 from the printing paper 22,
The light blocking member 148 is cut out from the starting end of the photographic printing paper 22.

Therefore, the light shielding member 1 as the leader tape
By introducing 48 into the guide groove 202, the light shielding member 148 can be easily pulled out from the opening 29, and even if the photographic paper 22 is stored in a bright room, the photographic paper 22 is exposed to light. There is nothing to do, and storage work becomes easy.

After storing the paper roll 21 in this manner, the magazine 18 is placed on the magazine table 46. When the operation handle 54 is rotated from the position shown by the chain double-dashed line to the position shown by the dotted line, the engagement of the roller 50 and the groove 48A causes
The plate 48 moves leftward together with the magazine table 46. During the movement of the magazine table 46, the loading detection sensor 5
When 6 is turned on, the controller causes the pulse motor M1 to rotate in the normal direction and is transmitted to the feed roller pair 28 via the paper supply gear system FG, so that the feed roller pair 28 rotates.

When the magazine handle 46 is moved by further rotating the operation handle 54, the magazine 18 is set at the loading completion position. Immediately before this loading is completed, the attachment / detachment detection pin 3
Since 4 hits the protrusion 38, the light-shielding shutter 30 moves against the spring 36 to open the paper port 26, and the bracket 152 and the support engaged with the small diameter portion 34A of the attachment / detachment detection pin 34 accordingly. The body 158 is reciprocally moved, and as shown in FIG. 11, the sandwiching roller 156 is moved to the sandwiching release position.

Immediately after this, the feed roller pair 28 rotates into the notch 26A of the paper port 26, and the leading edge of the photographic printing paper 22 is gripped by the feed roller pair 28. The leading end of the photographic paper 22 is the feed roller pair 2
When the pulse sensor M1 passes through 8 and is detected by the passage sensor 60, the forward rotation of the pulse motor M1 is stopped.

At this time, the guide groove 204 is formed by the light shielding member 14
8 and the guide roller 23 and the opening 29.
The photographic printing paper 22 positioned between and is guided while passing it through.

That is, printing paper 22
The tension generated when the paper is sent to the printer processor 10 side causes the photographic paper 22 to become a flat surface, climb over the wall portion 206, and move the photographic paper 22 from the guide groove 202 to the guide groove 204.
And is guided by the guide groove 204 and sent out. For this reason, the photographic printing paper 22 that is pulled out after the light shielding member 148 is drawn.
Even when the width dimension of the light shielding member 148 is different from that of the light shielding member 148, the width dimension of the guide groove 204 is adapted to the photographic printing paper 22 so that the photographic printing paper 22 can be conveyed without meandering.

From the above, when storing the photographic printing paper 22,
Since the nip roller 156 is at the nip release position, the light blocking member 148 can be easily introduced into the opening 29, and the opening / closing lid 18 can be stored after being stored.
When B is closed, the sandwiching roller 156 moves to the sandwiching position and does not rotate in the opposite direction.
Thus, the light blocking member 148 can be sandwiched. When the magazine 18 containing the printing paper 22 is attached to the printer processor 10, the nip roller 156 moves to the nip release position again and passes through the guide groove 204 matching the width dimension D2 of the printing paper 22. Together, the photographic paper 22 can be easily transported to the printer processor 10 side.

As a result, even when the magazine 18 is vibrated while the light-shielding member 148 is smoothly pulled out, the leading end side of the photographic printing paper 22 is not pulled into the magazine 18.

When the loading of the magazine 18 is completed in this way, the photo sensor 42 reads the paper information from the signal section 40 and sends it to the controller. This controller adjusts the width of the variable guide 72 and the size of the variable paper mask 86.

The rotation of the feed roller pair 28 causes the leading end of the photographic printing paper 22 to reach the main feed roller 114 via the exposure stage 84. This main feed roller 11
Since No. 4 is rotated by the pulse motor M2, the leading edge of the photographic printing paper 22 is gripped and sent out. When the leading edge of the printing paper 22 is detected by the passage detection sensor 120, the rotations of the pulse motors M1 and M2 are stopped.

After stopping the pulse motors M1 and M2, the motor 66 rotates to retract the guide cam 64 to the position shown by the solid line. Immediately after this, the pulse motor M1 rotates in the normal direction, and the photographic printing paper 22 pulled out from the magazine 18 forms a loop 70. When the loop 70 reaches a predetermined amount (at least one frame or more), the loop sensor 68 is turned on to stop the normal rotation of the pulse motor M1.

As described above, the paper loading is automatically performed only by loading the magazine 18, and the printing standby state is entered. Negative film 9 on film carrier
After setting 2, the keyboard (not shown) is operated to indicate the print, and the photometric unit (not shown) measures the frame on the negative film to be printed.
Various printing exposure amounts are calculated from the obtained photometric value and exposure information such as sensitivity and surface type, and the filter setting position of the filter section 98 is adjusted according to these printing exposure amounts.
After this filter adjustment, the black shutter 104 operates to print-expose the printing paper 22 set on the exposure stage 84.

When a negative film frame is printed and exposed on the photographic printing paper 22, the pulse motor M2 rotates a fixed amount to convey the photographic printing paper 22 for one frame. This causes the printed portion to be conveyed towards the loop 130 and the unprinted portion to be pulled out of the loop 70. This loop 70
When the loop amount is reduced, the loop sensor 68 is turned on, so that the pulse motor M1 is normally rotated to pull out the photographic paper 22 from the magazine 18 and send it into the loop 70. The pulse motor M1 rotates until the loop sensor 68 is turned off, and a predetermined amount of photographic paper 22 is constantly stocked in the loop 70.

When printing is performed a plurality of times, the printing paper 22
A passes over the guide cam 128 and the guide roller pair 12
Reach 6 Since the pulse motor M3 rotates the guide roller pair 126 after the start of printing, the approaching photographic paper 22 is gripped. When the photographic paper 22A is detected by the passage detection sensor 150, the pulse motor M
The rotation of 3 stops. Immediately after this, the motor 130 rotates to move the guide cam 128 to the retracted position shown by the solid line.

When printing is further continued, the printed printing paper 22 sent by the main feed roller 114 is stocked in the loop 130. Then, when a certain amount of the printed photographic paper 22 is stocked in the loop 130, the loop sensor 132 is turned on, so that the rotation of the pulse motor M3 is started. This pulse motor M
3 sends the printed printing paper 22 to the processor unit 14 at a constant speed. The processor unit 14 conveys the printed photographic printing paper 22 at a constant speed and sequentially passes through each processing tank to perform a photographic developing process.

In the above embodiment, the present invention is applied to the photographic printing paper 22 as a photosensitive material. However, the present invention is not limited to this. For example, a photosensitive material for developing a negative film is used. The present invention can be applied to a processing device.
