Description

[0001]
BACKGROUND OF THE INVENTION
The present invention guides and supports the unit so that it can move in parallel in a predetermined direction. Therefore, the first guide support part for guiding and supporting the first part of the unit is different from the first part of the unit. The present invention relates to a unit support mechanism including a second guide support portion that guides and supports two locations, and a photo processing apparatus including the unit support mechanism.
[0002]
[Prior art]
The prior art of such a unit and unit support mechanism will be described with reference to FIG. FIG. 5A is a bottom view, and FIG. 5B is a side view. The unit 60 is guided and supported so as to be movable in the direction of arrow D in the figure, and slide bearings 61, 62, and 63 are provided on the lower surface of the unit 60. The slide bearings 61 and 62 are slidable along a guide shaft 64 fixed to the apparatus main body, and the slide bearing 63 is slidable along a guide shaft 65 that is also fixed to the apparatus main body. ing. Such a unit support mechanism allows the unit 60 to move in parallel.
[0003]
[Problems to be solved by the invention]
However, such a unit support mechanism is expensive because it uses a slide bearing. Further, when the slide bearing is used, the parallelism of the two guide shafts 64 and 65 is required with high accuracy, and the assembly cost is high. Although it is conceivable to use a precision linear rail (LM guide or the like) in place of the slide bearing, the cost becomes even more expensive.
[0004]
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a unit support mechanism that can reduce the cost of a mechanism for moving the unit in parallel and a photographic processing apparatus including the unit support mechanism.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the unit support mechanism according to the present invention includes:
A first guide support portion for guiding and supporting the first portion of the unit in order to guide and support the unit so that it can be translated in a predetermined direction;
A second guide support part for guiding and supporting a second part different from the first part of the unit;
The first guide support portion includes a first roller and a first guide member that regulates a width direction of the first roller,
The second guide support portion includes a second roller and a second guide member that regulates an outer diameter direction of the second roller.
[0006]
According to this configuration, the unit is guided and supported at at least two locations of the first guide support portion and the second guide support portion. A roller is used to translate both the first and second guide support portions. By restricting the width direction or the outer diameter direction of the roller by a guide member, the unit is guided so that it can move in parallel. The unit support mechanism can be constructed at low cost because it uses a roller rather than a slide bearing.
[0007]
The first and second guide members may be provided on the unit side, and the first and second rollers may be provided on the main body side. The first and second rollers may be provided on the unit side, and the first and second rollers may be provided on the main body side. A second guide member may be provided.
[0008]
As a preferred embodiment of the present invention, the first guide support portion is provided to guide and support the lower portion of the unit, and the axial center of the first roller is set to be in a horizontal direction. The first guide member is disposed above or below the first roller;
The second guide support part is provided to guide and support the upper part of the unit, and the second guide support part is set so that the axis of the second roller is in the vertical direction.
[0009]
According to this structure, the 1st guide support part supports the lower part of a unit, and supports the load of a unit with a 1st roller. The first guide member is disposed on the upper side of the first roller, and by restricting the width direction thereof, a smooth parallel movement of the lower part of the unit is realized. On the other hand, the second guide support part guides and supports the upper part of the unit, and regulates the outer diameter direction of the second roller with the second guide member so that the axis of the second roller is in the vertical direction. Thus, the unit can be moved in parallel while maintaining the posture of the entire unit.
[0010]
As another preferred embodiment of the present invention, the first guide support portion is provided to guide and support the lower part of the unit, and is set so that the axis of the first roller is in a horizontal direction. And the first guide member is disposed above the first roller,
The second guide support part is provided to guide and support the side part of the unit, and the second guide support part is set so that the axis of the second roller is in the horizontal direction.
[0011]
The point that the load of the entire unit is supported by the first roller is the same as described above, except that the second guide support portion is provided on the side portion to maintain the posture of the entire unit. In this case, like the first roller, the second roller has a horizontal axis, and its outer diameter direction is regulated by the second guide member. Thereby, it can be translated while maintaining the posture of the entire unit properly.
[0012]
As still another preferred embodiment of the present invention, a third guide member is further provided in the unit, and the outer diameter direction of the first roller is regulated by the first guide member and the third guide member. What is composed is given.
[0013]
According to this configuration, since the outer diameter direction of the first roller is regulated by the first guide member and the third guide member provided in the unit, the first roller can be regulated with high accuracy.
[0014]
As still another preferred embodiment of the present invention, the first roller and the second roller are constituted by bearings whose outer rings are made of metal, the first guide member, the second guide member, and the third roller. The guide member is made of resin.
[0015]
When the guide portion is slid between metal, the moving sound becomes loud when the unit is moved in parallel. Therefore, the moving noise can be reduced by sliding the outer ring made of metal with the bearings and the guide members made of resin.
[0016]
In order to achieve the above object, a photo processing apparatus according to the present invention comprises:
A sorting unit capable of switching the photosensitive material from a single-row transport state to a multi-row transport state is provided, and this sort unit is a unit that is guided and supported by the unit support mechanism described above. .
[0017]
In some photographic processing apparatuses, after the exposure of the photosensitive material is completed in the exposure unit, the conveyance state is switched from one row to multiple rows in order to increase processing capability. A sorting unit is provided for switching the transport state, and the transport state is switched by translating the sorting unit in a direction orthogonal to the transport path of the photosensitive material. By using a roller as a unit support mechanism of this sorting unit, it can be constructed at low cost, and as a result, it can contribute to cost reduction of the photographic processing apparatus.
[0018]
