An auxiliary engaging piece 71d as an auxiliary engaging portion engageable with the guide groove 42 is further provided in a protruding manner.

The method of using the above reel will be described.

First, the fitting protrusion 56 of the guide stopper plate 52 constituting the first guide body 5 is fitted into the predetermined fitting groove 41 in accordance with the width of the photographic paper roll P to be set. The guide member 5 is attached to the support member 4. For example, when a photographic paper roll P having a width of 117 mm is set, 1
The fitting protrusion 56 of the guide stopper plate 52 is fitted into the fitting groove 41a for 17 mm. When the photographic paper roll P having a width of 120 mm is set, the first guide body 5 is set to be 117 mm wide. Is rotated 90 degrees in the circumferential direction with respect to the support 4 from the state in which the photographic paper roll P is set, and the fitting protrusion 56 of the guide stopper 52 is fitted into the fitting groove 41c for 120 mm. It is.

Subsequently, after the photographic paper roll P is inserted into and supported by the support 4, the second guide 6 is attached to the other end of the support 4 in the longitudinal direction.

To attach the second guide body 6 to the support 4, first, the operating portion 63 is rotated with respect to the casing 62 via the operating rod 63 c, and the ratchet pawls 71, 72.
By swinging 73 in the direction against the return spring 62e, the claw portions 71a, 72a, and 73a are retracted into the casing 62.
The guide body 6 is fitted to the other end of the support body 4 in the longitudinal direction, and inserted near the end face of the photographic paper roll P.

Then, the operator releases the operating rod 63c and rotates the operating portion 63 in the reverse direction by the spring force of the spring 63f, so that the engaging pieces 71c, 72c, 73c and the auxiliary engaging pieces 71d are guided by the guide grooves 42. , The second guide body 6 is rotated with respect to the support body 4 and the second guide body 6 is screwed until the inner surface of the guide plate 61 contacts the end surface of the photographic paper roll P. Let it do.

As described above, since the second guide body 6 is prevented from rotating in the direction of retreating with respect to the support body 4 by the action of the ratchet mechanism 7, both ends in the width direction of the printing paper roll P are prevented. The support 4 is reliably received by the guides 5 and 6.
It is held without careless play in the axial direction.

In the above-described second guide member 6, the operation portion 63 can be operated to move the support member 4 to a desired position instantaneously. For example, the width of the photographic paper roll P supported by the support member 4 is narrow. In this case, the second guide body 6 can be set immediately to the vicinity of the photographic paper roll P, so that workability is good.

By the way, when the photographic paper roll P having the maximum width usable in the photographic processing apparatus is supported on the support 4, the photographic paper roll P whose width dimension is wider than the standard due to a manufacturing error or the like, Alternatively, if the outer peripheral portion is shifted in the axial direction with respect to the axial center portion to be wider than the standard width by, for example, conveyance, even if manufactured in the standard, the engaging pieces 71c, 72c, and 73c will At least the rearmost engagement piece 73c and auxiliary engagement piece 71d come to a position where the guide groove 42 is not formed as shown in FIG.
In addition to the engaging piece 73c and the auxiliary engaging piece 71d, the guide groove 4
Since the engagement pieces 71c and 72c located on the second 2 also do not engage with the guide grooves 42, the second guide body 6 is not attached to the support body 4.

Therefore, it can be seen that the photographic paper roll P supported by the support 4 is of a nonstandard width, and the wide nonstandard photographic paper roll P is not carelessly set on the reel. When setting the photographic paper roll P having the largest possible width, the operator is prevented from erroneously attaching the second guide body 6 to the support 4.

On the other hand, when the photographic paper roll P having the maximum width usable in the photographic processing apparatus is supported on the support 4 and the photographic paper roll P has a width conforming to the standard, FIG.
As shown in (1), all of the engagement pieces 71c, 72c, 73c and the auxiliary engagement pieces 71d are engaged with the guide grooves 42, and the second guide body 6 can be immediately attached to the support body 4.

The torque limiter 703 is the second speed increasing gear 70.
When the load is applied to the torque limiter 703 and the second driven shaft 600b, the second load is applied to the torque limiter 703 and the second driven shaft 600b.
The speed increasing gear 702 is caused to slip and rotate.

The second reduction gear 802 constituting the reduction gear section 800 is supported by the second driven shaft 600b via a one-way clutch 803, and is engaged with the first reduction gear 801.

The one-way clutch 803 incorporated in the second driven gear 802 locks when the second reduction gear 802 rotates in the normal rotation direction (the normal rotation direction of the drive shaft 400) and locks the rotation of the second reduction gear 802. The structure is such that the power is transmitted to the second driven shaft 600b.

In the above configuration, the photographic paper carry-out port 22
At the time of forward rotation of the drive shaft 400 accompanying the feeding from the printing paper roll, the peripheral speed of at least the maximum roll diameter of the photographic paper roll P supported on the reel 3 via the reduction gear portion 800 of the rotation speed switching mechanism 900 is equal to the peripheral speed of the transport roller pair 500. Try to be slower than fast.

When the drive shaft 400 rotates in the reverse direction due to the rewinding of the photographic paper, the speed increasing gear 70
0, the peripheral speed of the photographic paper roll P at least at the minimum roll diameter is set to be faster than the peripheral speed of the conveying roller pair 500.

In the figure, reference numeral 602a denotes a toothed belt 602.
Is a tension pulley for applying tension to the pulley.

The operation of feeding and rewinding photographic paper in the magazine having the above structure will be described.

First, when the drive shaft 400 rotates forward by the drive of the drive device to feed the photographic paper, the first driven shaft 401 also rotates, and the transport roller pair 500 rotates forward.

Further, with the forward rotation of the drive shaft 400, the toothed pulley 601 rotates forward via the toothed belt 602, and the first reduction gear 80 integrally formed with the toothed pulley 601.
1 and the first speed increasing gear 701 also rotate forward, and the first speed reducing gear 8
01 and the forward rotation of the first speed increasing gear 701 are transmitted to the second reduction gear 802 and the second speed increasing gear 702.

At this time, the second speed increasing gear 702 tries to rotate faster than the second speed reducing gear 802, but the second speed reducing gear 802 is interlocked with the second driven shaft 600b by the locking operation of the one-way clutch 803. It is in. for that reason,
By the action of the torque limiter 703, the second speed increasing gear 70
2 rotates slip with respect to the second driven shaft 600b, and the second driven shaft 600b is rotated by the reduction gear unit 800 at a speed lower than the rotation speed of the drive shaft 400 that is rotating forward.

The forward rotation of the second driven shaft 600b is caused by the first to fourth driven gears 603 and 604 from the extension shaft portion 601b.
. 605, 606, to the input gear 4c of the reel 3, and further from the core shaft 4a to the torque limiter 4b.
And finally transmitted to the support 4 via the reel 3
The reel 3 rotates forward at a speed at which the peripheral speed of the photographic paper roll P supported is lower than the peripheral speed of the transport roller pair 5.

Therefore, the photographic paper is sent out from the carry-out port 22 in a state where a moderate tension is applied.

When the printing paper is sent out by the forward rotation of the conveying roller pair 500, the photographic paper roll P is also forcibly rotated in the same direction, and the peripheral speed of the photographic paper roll P becomes faster than the peripheral speed of the conveying roller pair 500. In such a case, slip occurs due to the torque limiter 4b incorporated in the support 4 of the reel 3, so that the photographic paper is always fed out with tension applied.

On the other hand, when the drive shaft 400 is rotated in reverse by the drive of the drive unit to rewind the photographic paper on the reel 3, the first
The driven shaft 401 also rotates in the reverse direction, and the transport roller pair 500 rotates in the reverse direction.

Further, with the reverse rotation of the drive shaft 400, the toothed pulley 601 reversely rotates via the toothed belt 602, and the first reduction gear 80 integrally formed with the toothed pulley 601.
The first and first speed increasing gears 701 also rotate in the reverse direction.

First reduction gear 801 and first speed increasing gear 70
1 is rotated by the second reduction gear 802 and the second speed increasing gear 7.
02 is also transmitted, and the second reduction gear 802 and the second speed-up gear 702 also rotate in the reverse direction. At this time, the one-way clutch 803 attached to the second reduction gear 802 is in a free state. The rotation of the reduction gear 802 is not transmitted to the second driven shaft 600b. Therefore, the second driven shaft 600b is
The rotation speed of the drive shaft 400, which is rotating in the reverse direction, is increased more than the rotation speed of the drive shaft 400 and rotates in the reverse direction.

The reverse rotation of the second driven shaft 600b is applied to the first to fourth driven gears 603 and 604 from the extension shaft portion 601b.
. 605, 606, to the input gear 4c of the reel 3, and further from the core shaft 4a to the torque limiter 4b.
And finally transmitted to the support 4 via the reel 3
The reel 3 reversely rotates at a speed at which the peripheral speed of the photographic paper roll P supported by the roller 3 is higher than the peripheral speed of the conveying roller pair 500, and winds up the photographic paper.

Since the photographic paper roll P rotates in the reverse direction with its peripheral speed being faster than the peripheral speed of the pair of conveying rollers 500, the photographic paper roll P supported on the reel 3 without slackening is obtained.
It is wound up.

In the above magazine, the reel 3
The photographic paper fed from the photographic paper roll P supported by the paper is fed to a turn roller 51 provided in the middle of the transport path in the magazine.
After the transfer direction is changed at 0, the paper is sent out to the carry-out port 22.
, The both edges of the printing paper in the width direction are formed by the flange portions 541 of the turn guides 540a and 540b and the guide pieces 5 of the first and second width regulating guide members 520 and 530.
Since the photographic paper is sequentially received by the transfer rollers 22 and 532, the photographic paper is not shaken from side to side, and further from the turn roller 510 to the carry-out port 22, the regulating body 560 further prevents the photographic paper from being bent in the width direction. Therefore, the photographic paper can be stably conveyed outside the outlet 22 as a whole.

Thus, in the above embodiment, the first and second
Flange portion 541 of turn guide 540a / 540b
Is a boss 542 inserted and supported by the turn roller 510.
As a result, the play and inclination of the turn roller 510 are suppressed, so that the guide of the printing paper by the flange portion 541 is further stabilized.

In addition, even when the width of the photographic paper is out of the specified range, the guide piece 531 of the second width regulating guide member 530 urges the first width regulating guide member 520 by the spring reaction force of the coil spring 533. The printing paper is pushed toward the first width regulating guide member 520 so that both edges in the width direction of the printing paper are always guided by the guide pieces 521 of the two regulating guides 520 and 530.
The printing paper is stably conveyed by the guide pieces 521 and 531 in sliding contact with 531.

In the above embodiment, the first guide 5, the first turn guide 540a, and the first width guide 540a, and the first width guide 540a, the first turn guide 540a, the first width Since the transport direction of the photographic paper is determined by the regulating guide member 520, the photographic paper supported on the reel 3 can be transported accurately and in a stable state.

In the above embodiment, the present invention is applied to a magazine for setting a roll of photographic paper. However, the present invention is not limited to this, and is applied to a magazine for setting a film wound in a roll. Is also good.
