DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet conveying apparatus for conveying a sheet subjected to predetermined processing and a photographic processing apparatus using the sheet conveying apparatus.

[0002]

2. Description of the Related Art In a photographic processing apparatus, a photosensitive material (photographic paper) wound into a roll is cut into a predetermined size by a cutter, and an image on a negative film stretched to a predetermined size is exposed. After that, it is transported to a development processing unit and undergoes development, bleaching, fixing, and stabilization processing (the whole is referred to as development processing). The developed photosensitive material is conveyed to a drying unit, dried, and then discharged onto a tray outside the apparatus.

[0003] In general, the order (ordering unit) is a type of simultaneous printing in which one to several images of all the frames on the film are printed in a service size or a post card size simultaneously with the development of the film. Also, there are prints in which only a plurality of images of a specific frame on a film are printed or enlarged and printed. In recent years, a camera using a 135-size film or a film of a so-called new photographic system includes, in addition to a frame shot in a standard size on one film, a frame shot in a panorama size or a high-definition size.

In a conventional photographic processing apparatus, in order to arrange developed photographs in the order of photographing, photographs to be further discharged by a belt conveyor from an outlet of a drying unit are sequentially fed side by side, and an accumulation unit including a stocker and a tray is provided. It is known that the information is accumulated for each order.

FIG. 9 is an exploded perspective view showing a belt conveyor in a configuration example of a conventional photographic processing apparatus, and FIG.
FIG. 11 is a view taken in the direction of the arrow A, and FIG. 11 is a view taken in the direction of the arrow BB. As shown in FIG. 9, a belt conveyor in a conventional photographic processing apparatus includes rollers 111 and 112 arranged in parallel, a support member 113 for rotatably supporting both rollers, and a support member 11.
Conveyor belt 1 with 3 inside and wound around both rollers
A pulley 116 for transmitting a driving force from a motor 115 is provided at one end of an upstream roller 111 of the two rollers. By driving the conveyor belt 114 to rotate around the pulley 116 and the rollers 111 and 112 by the motor 115, a photograph (not shown) placed on the belt surface is transferred to the upstream side.

[0006] Of these, the support member 113 has upright walls 113a, 113a on both sides, and the upright walls 113a, 113a.
Rollers 111 and 112 are pivotally supported at the front and rear ends of the roller 13a, and a flat portion 113b having an upper surface substantially coincident with a surface connecting the upper ends of the peripheral surfaces of the rollers is provided between the two rollers. Cover walls 113c and 113d that cover and have a downwardly inclined surface are provided with upright walls 113a,
It is formed so as to be substantially symmetrical on the outside in the width direction of 113a. A plurality of ribs 113e, 113e,... Having the same height are formed in the width direction on the upper surface of the flat portion 113b of the support member 113 in parallel with the upstream and downstream directions. 113
The frictional resistance due to contact with the contact is reduced.

As shown in FIG. 10, a projecting belt core 114a that is continuous in the upstream and downstream directions is formed on the rear surface at the center in the width direction of the conveyor belt 114.
As shown in FIG. 11, the belt core 114a
Are formed. Roller 112
The same applies to. When the belt core 114a is loosely fitted into the groove 111a or the like, the transport belt 114 is prevented from being displaced sideways and coming off the rollers 111 and 112 when the transport belt 114 rotates around.

[0008] Photograph 1d discharged outside the photoprocessing device
Are successively dropped on a belt conveyor, but if the size is small, they will fit on the belt surface of the conveyor belt 114, so that there is no particular problem. However, as shown in FIG. 10, when the size of the photograph 1d is large, the belt surface of the transport belt 114 may protrude. If the protruding portions are covered by the cover walls 113c, 113c
d, the contacted photograph 1d falls off the belt surface of the conveyor belt 114, or its direction changes even if escaped, and the photograph 1d is aligned in the collecting section. There is a possibility that such a problem that it is difficult to stack the sheets in such a manner. Therefore, conventionally, even when the size of the photograph 1d is large, the portion of the conveyor belt 114 that protrudes from the belt surface is bent,
An inclined angle (about 20 ^° ) is provided on each inclined surface so as not to contact the inclined surfaces of the cover walls 113c and 113d.

[0009]

As described above, when the photograph 1d is conveyed, the photograph 1 protrudes from the conveyor belt 114.
In a case where an inclined angle is provided on each inclined surface such that d does not contact the cover wall portions 113c and 113d, as shown in FIG. 11, when the pulley 116 is installed in the cover wall portion 113c, the pulley 116 and the inclined surface , A dead space D that cannot be ignored is generated. Thereby, the rollers 111,
The diameter of 112 increases and the overall height of the belt conveyor increases. Further, in order to secure the number of photographs 1d to be accumulated in the accumulation section, the height of the photograph discharge end of the belt conveyor needs to be higher than the accumulation section by at least one order of the photographs 1d. On the other hand, since the total height of the photographic processing apparatus is limited by the installation space, it is desirable that the total height of the belt conveyor be as small as possible.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art, and is intended to provide a sheet conveying apparatus which can reduce the overall height of the apparatus with a simple structure and a photographic processing apparatus using the same. It is intended to provide.

[0011]

In order to achieve the above object, a sheet conveying apparatus according to a first aspect of the present invention has upright walls on both sides and supports rollers arranged in parallel at the front and rear ends thereof. And a cover wall between the two rollers, the flat wall having an upper surface substantially matching the surface connecting the upper ends of the peripheral surfaces of the two rollers, and covering a portion supporting the rollers and having a downwardly inclined surface. A support member having a portion formed on the outer side in the width direction of the vertical wall, a transport belt having the support member therein and being wound between the rollers, and a driving force applied to one end of the upstream roller among the two rollers. A sheet conveying device that conveys a sheet mounted on the surface of the conveying belt to the upstream side by driving the conveying belt to rotate through the driving transmitting unit and the rollers. The conveyor belt has a surface Of the width direction it is characterized in that the projecting portions along the upstream and downstream directions on a side where the driving force transmitting portion is provided is formed.

[0012] According to this configuration, the conveyed belt has, on the surface thereof, the protruding portion along the upstream and downstream directions on the side of the width direction where the drive transmission portion is provided, so that the conveyed sheet-like body is formed. By lifting up with this projection,
Even if the slope of the cover wall on the side where the drive transmission section is provided is set to a shallower angle than the slope of the cover wall on the side where the drive transmission section is not provided, the sheet-shaped body still has the drive transmission section. There is almost no risk of contact with the inclined surface of the cover wall on the side where the part is provided. Therefore, by setting the drive transmission unit closer to the inclined surface of the cover wall by an amount corresponding to the reduced inclination angle of the inclined surface of the cover wall on the side where the drive transmission unit is provided, a dead space therebetween is provided. Can be reduced, so that the roller diameter can be reduced. On the other hand, with respect to the inclined surface of the cover wall portion on the side where the drive transmission portion is not provided, even if the roller diameter is reduced, without providing the protrusions, a sufficient amount of the conveyed sheet-shaped body does not come into contact. A large inclination angle can be secured. This makes it possible to reduce the overall height of the sheet conveying device.

Further, a plurality of ribs parallel to the upstream and downstream directions are formed on the upper surface of the support member in the width direction, and the protrusion is formed by making the height of the rib higher than other ribs. In this case (claim 2), the side of the sheet-like body to be conveyed on which the drive transmission unit is provided is more protruding than the side on which the drive transmission unit is not provided via a conveyor belt. It can be lifted higher by the difference in height. Therefore, it is possible to reduce the overall height of the sheet conveying device with a simple configuration.

Further, the transport belt is formed to have a constant thickness in the upstream and downstream directions, and the projecting portion is formed so that the transport belt has a greater thickness in the width direction than other portions. Item 3), the side of the sheet-like body to be conveyed, on which the drive transmission unit is provided, can be lifted higher than the side on which the drive transmission unit is not provided, by a difference in thickness in the width direction of the conveyance belt. Therefore, it is possible to reduce the overall height of the sheet conveying device with a simple configuration.

Further, the projecting portion has a projecting amount such that a deflection angle of the sheet-like body in a width direction of the conveyor belt is smaller than about 20 ^° on a side where the drive transmitting portion is provided. In this case (claim 4), the side on which the drive transmission section is provided of the conveyed sheet-like body can be lifted by this projection amount higher than the side on which the drive transmission section is not provided. Therefore, with a simple configuration,
The overall height of the sheet conveying device can be reduced.

Further, in the photographic processing apparatus of the present invention, the sheet is a photograph which has been subjected to a developing process and a drying process, and any one of the above-described sheet conveying devices can be used. 5).

As described above, with a simple configuration, it is possible to obtain a sheet conveying apparatus and a photographic processing apparatus using the sheet conveying apparatus, which can secure the number of sheets to be accumulated and can further reduce the height of the apparatus. it can.

At least at the beginning of the entire development step and the fixing step, No exposure to stray light from outside. Therefore, the development processing unit 40
The inside 401 of 0 is configured as a dark room. In the inside 401 of the development processing unit 400, for example, development processing tanks 402 and 403, bleach-fix processing tanks 404 and 405, and stabilization processing tanks 406 to 408 are arranged in this order. In order to sequentially transport the photosensitive material at a constant speed, a photosensitive material transport mechanism 409 including a transport roller and a transport belt is provided. The photosensitive material 1c that has come out of the last stabilization processing liquid tank 408 is conveyed to the drying unit 500 after the processing liquid adhering to the surface is wiped off by the squeeze roller 212. Below the drying unit 500, a blower 220 for blowing warm air into the drying unit 500 is provided. The details of the drying unit 500 will be described later.

The photosensitive material 1d conveyed to the drying unit 500 and dried (ie, a photograph as a finished product) 1d is
After being discharged from the discharge port 501 on the upper part of the drying unit 500, sequentially dropped on the first transporting device 100, the transporting direction is changed by 90 degrees, and then, 1 is transferred onto the belt transporting portion 151 of the second transporting device 150. Only the order (for example, the number of frames shot on one film) is stacked.
When the processing for one order is completed, the belt transport unit 151 is moved, and the photos of the next order are stacked on another portion on the belt transport unit 151. Belt transport unit 15
On one, photos of a plurality of orders can be held.

Next, details of the structure of the exposure unit 300 are shown in FIG. Below the light source 311 and the mirror unit 312 of the exposure device 310,
The film 2 is held at a position facing the opening of the mirror unit 312 by a film holder (not shown).

The enlargement lens unit 250 includes a film holder (not shown) for holding a negative film to be printed, a lens moving deck 260 for mounting a lens 251 such as a zoom lens, and a lens moving deck 2.
A ball screw mechanism 252 for driving 60 in the X direction;
It is mounted on the lens moving deck 260 and is constituted by a mirror 253 and the like for bending the traveling direction of the light transmitted through the negative film by approximately 90 degrees and guiding it to the optical sensor 254.

Below the stretching lens unit 250, there is provided an exposure table 305 constituted by a transport belt 305a and the like for sucking and holding the cut photosensitive material 1b and transporting it in the X direction. The exposure surface of the exposure table 305 is arranged substantially horizontally.

Below the exposure table 305, a magazine 301 is loaded in a magazine loading mechanism 302 (see FIG. 2A) so that the photosensitive material 1 is pulled out substantially vertically upward from the magazine 301. A drive roller 303 for transporting the photosensitive material 1 extracted from the magazine 301 onto a transport belt 305a and a cutter 304 for cutting the photosensitive material 1 are provided on a part of the exposure table 305 above the magazine 301.
Is provided. The photosensitive material 1 pulled out substantially vertically upward from the magazine 301 is wound around a drive roller 303 by a guide plate, a driven roller, and the like (not shown).
After the conveyance direction is changed in a substantially horizontal direction, the sheet is cut into a predetermined length by the cutter 304.

In the state where the cut photosensitive material 1b is suction-held on the exposure surface of the exposure table 305, the mirror unit 31
2, the center of the image (frame) of the film 2, and the center of the cut photosensitive material 1 b, respectively.
It almost coincides with the optical axis of the first optical system. The focal length of the optical system of the lens 251 and the position of the optical system are adjusted in advance so that the image of the image (object) on the film 2 is formed (focused) on the photosensitive material 1b. When the shutter is opened in this state, the photosensitive material 1b is exposed.

The exposed photosensitive material 1b is located downstream of the exposure table 305 in the transport direction (X direction) of the photosensitive material 1b.
a printing device 306 for printing a predetermined symbol on the back surface (the side on which the emulsion layer is not applied) of b. A distribution device 307 for distributing to the road is provided. The distributing device 307 includes the photographic processing device 200
Exposure unit 300 and developing unit 4 provided inside
It moves up and down along a substantially vertical partition wall 320 that separates 00 and 00. The cut photosensitive material 1b is nipped by the distribution device 307, passes over the partition wall 320, and is
Transported to 0.

For example, in the case of a photo processing apparatus 200 capable of processing a photograph of six slices (8 inches × 10 inches),
The width of the photosensitive material transport path of the developing unit 400 and the drying unit 500 is set to 8.5 inches. However, a stretched photograph such as a six-cut size has a high unit price and is not processed in such a large amount. On the contrary,
Photos of so-called service sizes are processed in large quantities.
Therefore, in order to increase the processing efficiency, for example, when the width of the photographic or photosensitive material is 4 inches or less, the material is sorted and transported in a plurality of rows by the sorting device 307, and the developing process and drying are performed.

FIG. 4 shows an example of a method of transporting the photosensitive material. The photosensitive materials 1A to 1F are in the same order. In the order of exposure, 1A is the left column, 1B is the right column
・ The last 1F is transported to the center. That is, when only a specific portion of the photosensitive material transport path is used, dirt or the like adheres to an unused portion (for example, a central portion). When the wide photosensitive material 1G is conveyed,
Band-like unevenness of development or the like appears in that portion. In order to prevent this phenomenon, the photosensitive material 1F is conveyed in the central part, one for every several sheets. Note that the photosensitive materials 1A to 1E conveyed separately are arranged in a so-called staggered manner such that the front end and the rear end overlap in the conveying direction.
The same applies to a panoramic size such as 1D.

Next, the details of the upper part of the photographic processing apparatus 200, particularly the upper part of the developing unit 400, are shown in FIG. The photograph 1d dried by the drying unit 500 and discharged to the outside of the photographic processing apparatus 200 is discharged from the discharge port 501 at the upper part of the drying unit 500, and is sequentially dropped on the first transport device 100. The first conveying device 100 is a belt conveyor, and assuming that the conveying direction (X direction) of the photosensitive material inside the photographic processing device 200 is the first direction, the belt conveying portion 101 is in the second direction (the second direction orthogonal to the first direction). The photograph 1d is transported in the Y direction).

The transport side end 100a of the first transport device 100
In the vicinity, the second transfer device 150 and the second transfer device 150
A guide plate 160 is provided to face the transfer side end 100a of the first transfer device 100 with the space therebetween. The second conveyor 150 is also a belt conveyor, and its belt conveyor 15
Reference numeral 1 functions as a tray for receiving the photographs 1d transported in the second direction (Y direction) by the first transport device 100, and re-transfers the photographs 1d stacked thereon in the first direction (X direction). Transport.

Inside the drying unit 500 and near the discharge port 501, a sensor (not shown) for detecting the passage of the rear end of the dried photograph 1d is provided. When the sensor detects the passage of the rear end of the photograph 1d, the first transport device 100 is activated, and is discharged onto the belt transport unit 101 of the first transport device 100 until the next photo 1d 'is discharged. The photograph 1d is transferred onto the belt transport section 151 of the second transport device 150. The photograph 1d that protrudes in the second direction (Y direction) from the transfer side end 100a of the first transfer device 100 abuts on the guide plate 160, and the second transfer device 150
Falls in a relatively limited fixed range on the belt conveyance unit 151 of the first embodiment.

Since the number of prints for each order is known in advance when the operator operates the operation panel 230 shown in FIG. 1, the above sensor detects the end of the last photograph of one order (for example, 1F in FIG. 4). After a certain period of time has passed after the detection of the passage, the second transport device 150 is driven, and the photographs 1d stacked on the belt transport unit 151 move in the first direction (X direction) by a predetermined distance.

The second transport device 150 is provided for the photographic processing device 20.
The developing unit 400 is provided along the first direction (X direction), which is the photosensitive material transport direction, on the upper part of the developing unit 400, and a plurality of orders of the photograph 1d can be placed on the belt transport unit 151. It is. As is apparent from FIG. 1, the end 151 a of the belt transport unit 151 of the second transport device 150
Is near the operation panel 230. That is, the operator of the photo processing apparatus operates the operation panel 230 and the like to input the number of the frame to be printed and the number of prints at the same position without moving, and packs the already printed photos together with the negative film. And work efficiency is improved.

FIG. 6 is an exploded perspective view showing an example of the configuration of the first transfer device, FIG. 7 is a view taken along the line AA, and FIG. 8 is a view taken along the line BB. As shown in FIG. 6, the first transport device 100 includes rollers 111 and 112 arranged in parallel, a support member 113 for rotatably supporting both rollers, and a support member 113.
Conveyor belt 11 wound around both rollers with
4, a pulley 116 for transmitting a driving force from a motor 115 is provided at one end of an upstream roller 111 of the two rollers. The reason why the pulley 116 is provided on the roller 111 on the upstream side is that it is necessary to apply tension to the belt surface. Then, by driving the conveyor belt 114 around the pulley 116 and the rollers 111 and 112 by the motor 115, the photograph 1d placed on the belt surface is transferred to the upstream side.

Of these, the support member 113 has upright walls 113a, 113a on both sides.
Rollers 111 and 112 are pivotally supported at the front and rear ends of the roller 13a, and a flat portion 113b having an upper surface substantially coincident with a surface connecting the upper ends of the peripheral surfaces of the rollers is provided between the two rollers. Cover walls 113c and 113d that cover and have a downwardly inclined surface are provided with upright walls 113a,
113a is formed outside in the width direction. Cover wall 1
13c has a role as a protective cover for protecting an operator or the like from the pulley 116, and the cover wall 113d is a decorative cover having no such role. In the present embodiment, the support member 113 has a projection 113f formed on the upper surface thereof along the upstream and downstream directions on the side where the pulley 116 is provided in the width direction. For this reason, unlike the above-mentioned conventional example, the cover portion wall portions 11 on both sides are provided.
3c and 113d have different downward inclination angles.

A plurality of ribs 113e, 113e,... Parallel to the upstream and downstream directions are formed in the width direction on the upper surface of the flat portion 113b of the support member 113 so as to contact the support member 113 when the transport belt 114 is driven to rotate. The frictional resistance is reduced. In the present embodiment, the protrusion 1
13f, the height of the rib 113e1 is
e, 113e,... Therefore, the side on which the pulley 116 of the photograph 1 to be conveyed is provided is higher than the side on which the pulley 116 is not provided via the conveyor belt 114 by the difference in height between the ribs.

As shown in FIG. 7, a protruding belt core 114a which is continuous in the upstream and downstream directions is formed on the rear side of the center of the conveying belt 114 in the width direction.
In FIG. 1, a groove 111a corresponding to the belt core 114a is formed as shown in FIG. The same applies to the roller 112. Then, the belt core 1 is inserted into the groove 111a or the like.
14a is loosely fitted into the conveyor belt 11
The transport belt 114 is prevented from being displaced sideways and coming off the rollers 111 and 112 during the circulating drive of No. 4. In the present embodiment, in order to lift a part of the transport belt 114, the belt core 114a is made slightly larger than that in the conventional example for safety.

In FIG. 1, the photograph 1d discharged to the outside of the photographic processing apparatus 200 is discharged from the discharge port 501 on the upper part of the drying unit 500 and dropped on the first transporting device 100 as described above. However, if the size is small, it fits on the belt surface of the conveyor belt 114,
There is no particular problem. However, as shown in FIG. 7, when the size of the photograph 1d is large, the photograph 1d may run off the belt surface of the transport belt 114 in some cases. If the protruding part is the cover wall 113c,
If the photograph 1 comes into contact with the inclined surface 113d, the photograph 1 falls off from the belt surface of the conveyor belt 114, or its direction changes even if it escapes from the belt surface. As described above, there is a possibility that a problem that it becomes difficult to align and stack the photographs 1d in the above manner. In this regard,
In the present embodiment, the photograph 1d to be conveyed is the projection 11
Since the photograph 1d is lifted upward at 3f, the deflection of the photograph 1d is slightly smaller on the side with the protrusion 113f (provided with the pulley 116) than on the side without the protrusion 113f (without the pulley 116). Therefore,
Even if the inclination angle of the inclined surface of the cover portion wall 113c on the side where the pulley 116 is provided is smaller than about 20 ^° , there is almost no possibility that the photograph 1d will contact the inclined surface of the cover portion wall 113c.

As described above, in the present embodiment, the pulley 116
The pulley 116 is connected to the cover wall 113c by an amount corresponding to the shallower inclination angle of the inclined surface of the cover wall 113c on the side where the cover wall 113c is provided.
8, the dead space D during this time can be made smaller than that in the conventional example, as shown in FIG.
Can be reduced in diameter. On the other hand, pulley 116
Regarding the inclined surface of the cover wall portion 113d on the side where no is provided, even if the diameter of the roller 111 is reduced, without providing the protrusion 113f, a sufficiently large inclination is provided so that the conveyed photograph 1d does not contact. The angle can be secured.
Similarly, the diameter of the roller 112 can be reduced. Accordingly, the diameter of the rollers 111 and 112 can be reduced, and the overall height of the first transport device 100 can be reduced. As described above, even when the photograph 1d is lifted only on the cover wall 113c side, the height of the highest part at the center in the width direction of the photograph 1d hardly changes, and the photograph 1d on the cover wall 113d side sinks. There is no problem because it is slight. As a result, the number of photos 1d to be stacked can be ensured, and the overall height of the photo processing device 200 can be reduced from the viewpoint of securing space.

In the above embodiment, the protrusion 113f
Although the rib 113e1 on the side where the pulley 116 is provided among the ribs 113e provided continuously along the upstream and downstream directions of the support member 113 is projected more than the other rib 113e over the entire length of the rib 113e1, Only the pulley 113e1 and its vicinity may be gradually projected.

Further, in the above-described embodiment, the pulley 116 is exemplified as the drive transmission unit for transmitting the driving force of the motor 115 to the roller 111. However, a transmission method using gears or the like does not cause any problem.

Further, in the above embodiment, the support member 11
Although the protrusion 113f is formed by the difference in the rib height of No. 3, the protrusion 113f may be formed instead by changing the thickness of the transport belt 114 in the width direction. For example, the transport belt 114 may be formed to have a constant thickness in the upstream and downstream directions, and the thickness in the width direction may be greater than other portions. In that case, the pulley 1 of the photograph 1d to be conveyed
The side on which the pulley 116 is provided can be raised higher than the side on which the pulley 116 is not provided by the difference in the thickness of the transport belt 114 in the width direction. Therefore, also in this case, the overall height of the first transfer device 100 can be reduced with a simple configuration.

According to this configuration, the conveyed belt is formed with a protruding portion along the upstream and downstream directions on the surface where the drive transmission portion is provided in the width direction, so that the conveyed sheet-like body is formed. By lifting up with this projection,
Even if the inclined surface of the cover wall portion on which the drive transmission portion is provided is formed at a shallower angle than the inclined surface of the cover wall portion on which the drive transmission portion is not provided, the sheet-shaped body has the drive transmission portion. There is almost no risk of contact with the inclined surface of the cover wall on the side where the part is provided. Therefore, by setting the drive transmission unit closer to the inclined surface of the cover wall by an amount corresponding to the reduced inclination angle of the inclined surface of the cover wall on the side where the drive transmission unit is provided, a dead space therebetween is provided. Can be reduced, so that the roller diameter can be reduced. On the other hand, with respect to the inclined surface of the cover wall portion on the side where the drive transmission portion is not provided, even if the roller diameter is reduced, without providing the protrusions, a sufficient amount of the conveyed sheet-shaped body does not contact. A large inclination angle can be secured. This makes it possible to reduce the overall height of the sheet conveying device.

Further, a plurality of ribs parallel to the upstream and downstream directions are formed on the upper surface of the support member in the width direction, and the protrusions are formed by making the height of the ribs higher than other ribs. In this case (claim 2), the side of the sheet-like body to be conveyed on which the drive transmission unit is provided is more protruding than the side on which the drive transmission unit is not provided via a conveyor belt. It can be lifted higher by the difference in height. Therefore, it is possible to reduce the overall height of the sheet conveying device with a simple configuration.

Further, the transport belt is formed to have a constant thickness in the upstream and downstream directions, and the projecting portion is formed so that the transport belt has a greater thickness in the width direction than other portions. Item 3), the side of the sheet-like body to be conveyed, on which the drive transmission unit is provided, can be lifted higher than the side on which the drive transmission unit is not provided, by a difference in thickness in the width direction of the conveyance belt. Therefore, it is possible to reduce the overall height of the sheet conveying device with a simple configuration.

Further, the projecting portion has a projecting amount such that the deflection angle of the sheet-like body in the width direction of the conveyor belt is smaller than about 20 ^° on the side where the drive transmitting portion is provided. In this case (claim 4), the side on which the drive transmission section is provided of the conveyed sheet-like body can be lifted by this projection amount higher than the side on which the drive transmission section is not provided. Therefore, with a simple configuration,
The overall height of the sheet conveying device can be reduced.

Further, in the photographic processing apparatus of the present invention, the sheet is a photograph which has been subjected to a developing process and a drying process, and any one of the above-mentioned sheet conveying devices can be used. 5).

As described above, with a simple configuration, it is possible to obtain a sheet conveying apparatus and a photographic processing apparatus using the sheet conveying apparatus capable of securing the number of sheets to be accumulated and further suppressing the height of the apparatus. it can.
