Field of the Invention The present invention relates to a magazine storage for loading a photographic paper magazine, and photographic paper transport means for transporting photographic paper drawn from the photographic paper magazine loaded in the magazine storage. And an image exposing unit that is arranged in the middle of the conveyance path of the photographic paper conveying unit and forms an exposure image on the photographic paper is provided in the apparatus housing, and the apparatus housing is provided near the magazine storage unit. A first maintenance door that is arranged and opened and closed for maintenance of a photographic paper magazine or equipment disposed near the photographic paper magazine, and for maintaining equipment other than the equipment that is maintained from the first maintenance door. Second
The present invention relates to an image exposure apparatus provided with a maintenance door, wherein opening and closing of the first maintenance door and opening and closing of a photographic paper drawer of the photographic paper magazine are operated in conjunction with each other.

[0002]

2. Description of the Related Art Such an image exposing apparatus draws a photographic paper from a photographic paper magazine loaded in a magazine storage section in an apparatus housing and conveys the photographic paper. It is an apparatus to be manufactured. A first maintenance door is provided near the magazine storage section in the apparatus housing of the image exposure apparatus for replacing a photographic paper magazine or for maintaining equipment near the magazine storage section. When the first maintenance door is opened for replacement of the photographic paper magazine or for maintenance of equipment in the vicinity of the magazine storage section, light in the apparatus housing is turned on. When the first maintenance door is opened and operated by interlocking the opening and closing of the first maintenance door and the opening and closing of the light-blocking shutter provided in the photographic paper draw-out opening of the photographic paper magazine by the mechanism, The shutter of the photographic paper drawer opening of the magazine is closed and operating.

On the other hand, since the first maintenance door alone cannot cover all devices in the apparatus housing, the first maintenance door is further opened and operated on the apparatus housing of the image exposure apparatus. A second maintenance door for maintenance of equipment other than the equipment to be maintained. The second maintenance door is used, for example, for maintenance of an image exposure unit that forms an exposure image on photographic paper, a photographic paper transport unit, and the like. Conventionally, unlike the case of the above-described first maintenance door, the opening and closing of the second maintenance door and the opening and closing of the shutter of the photographic paper drawer of the photographic paper magazine are not linked. This is because the light entering from the second maintenance door is less likely to reach the photographic paper draw-out opening of the photographic paper magazine than the light entering from the first maintenance door, so the photographic paper is wound around the photographic paper magazine. When the photographic paper is pulled out of the photographic paper magazine again after the maintenance work is performed in step (1), the leading end of the drawn photographic paper can be cut off by a small length to cope with the problem.

[0004]

However, from the viewpoint of effective use of the photographic paper, it is not preferable that the leading end of the photographic paper has a portion that is not used for print production as described above, and improvement has been desired. . The present invention has been made in view of such circumstances, and has as its object to effectively use photographic paper with a simple configuration.

[0005]

According to the first aspect of the present invention, a magazine storage portion for loading a photographic paper magazine and a photographic paper magazine loaded in the magazine storage portion are drawn out of the magazine storage portion. Photographic paper transport means for transporting the photographic paper, and image exposure means arranged in the transport path of the photographic paper transport means to form an exposure image on the photographic paper are provided in the apparatus housing, and On the body,
A first maintenance door that is arranged near the magazine storage unit and that is opened and closed for maintenance of the photographic paper magazine or a device arranged near the magazine, and a device that is maintained from the first maintenance door. An image provided with a second maintenance door for maintaining another device, wherein opening and closing of the first maintenance door and opening and closing of a photographic paper drawer of the photographic paper magazine are operated in conjunction with each other. In the exposure apparatus, the opening operation of the second maintenance door is prevented when the first maintenance door is closed, and the first operation is performed when the second maintenance door is open.
A maintenance door linkage mechanical linkage mechanism for preventing the maintenance door from closing is provided.

Therefore, the second maintenance door cannot be opened when the first maintenance door is closed due to the operation of the mechanical linkage mechanism for maintaining the maintenance door. After the first maintenance door is opened, the first maintenance door is opened. When the second maintenance door is opened and the second maintenance door is opened, the shutter provided at the photographic paper drawer of the photographic paper magazine is already closed. And
When the second maintenance door is open, the first maintenance door cannot be closed, and the first maintenance door is first closed after the second maintenance door is closed. It is possible to prevent the shutter provided at the photographic paper drawer opening of the photographic paper magazine from being opened in the state in which is opened.

That is, in order to close the shutter provided at the photographic paper drawer opening of the photographic paper magazine when opening not only the first maintenance door but also the second maintenance door, for example, A configuration is also conceivable in which the opening and closing of the first maintenance door and the second maintenance door are detected by a sensor, and the shutter provided at the printing paper draw-out opening of the printing paper magazine is opened and closed by an actuator. With the mechanical link mechanism for linking the maintenance door with the above configuration, a slight mechanism is added, making use of the conventional link mechanism that links the opening and closing of the first maintenance door with the opening and closing of the photographic paper magazine drawer. The above-mentioned object can be achieved with a simple configuration.

[0008] In addition, with the above configuration, a further effect can be produced. In other words, in an image exposure apparatus or the like, it is generally necessary to configure such that when a door provided in the apparatus housing is opened and operated, the power of the equipment housed therein is shut off. In a configuration in which the maintenance door and the second maintenance door can be opened and closed independently, it is necessary to provide each door with a sensor for detecting opening and closing.
However, with the configuration according to claim 1, the first maintenance door is always opened when the second maintenance door is open, and the second maintenance door is opened when the first maintenance door is closed. Since the door is always closed, the sensor for detecting the opening and closing of the door only needs to be provided for the first maintenance door only, so that the configuration of the apparatus can be simplified also in this respect.

[0009] Further, with the above configuration, the mechanical link mechanism for linking the maintenance door includes the first door.
A first movable member that can be switched between a blocking position for preventing movement of the maintenance door to the closed position and an allowable position for allowing movement to the closed position, and blocking for opening the second maintenance door; A second movable member that can be switched between a posture and an allowance posture that allows the opening operation, wherein the first movable member moves from the blocking posture with the second maintenance door closed with the closing operation. When the second maintenance member is switched to the allowable posture and the second maintenance door is opened, the switching from the allowable posture to the blocking posture is performed, and the second movable member closes the first maintenance door. The first maintenance door is switched from the blocking position to the allowable position as the first maintenance door is opened.

Therefore, as described above, the first maintenance member is closed when the first maintenance door is in the closed state by the action of the first movable member and the second movable member that are switched between the blocking position and the allowable position, respectively. (2) The opening operation of the maintenance door is prevented, and the closing operation of the first maintenance door is prevented when the second maintenance door is open. Thus, the photographic paper can be effectively used with a simple configuration.

Further, by providing the structure of the third aspect, the first maintenance door is configured to swing and open and close and is disposed on a side surface of the apparatus housing, and the second maintenance door is swingable. It is of a dynamic opening and closing type and is arranged on the upper surface of the device housing. When the first maintenance door and the second maintenance door are arranged in this manner, the directions of movement near the closed position have a relationship of intersecting with each other, so that the two can be easily interacted with each other, and the mechanical linkage for linking the maintenance door. It is particularly suitable for simplifying the structure of the mechanism.

In addition, with the above-mentioned structure, the first movable member is vertically movable and biased between the blocking position on the upper side and the allowable position on the lower side. The first maintenance door is biased upward by the means, and in the blocking position, abuts on a part of the first maintenance door to be closed or a member interlocked therewith, whereby the first maintenance door is The second maintenance door is configured to be prevented from moving to the closed position.
The first movable member is configured to be pushed down from the blocking posture toward the allowable posture. That is,
A first maintenance door for preventing the first maintenance door from moving to the closed position;
The movable member can be constituted by a member that only moves up and down in conjunction with the opening and closing of the second maintenance door, so that the mechanical linkage mechanism for linking the maintenance door can be further simplified.

[0013] Further, with the configuration according to the fifth aspect, the second movable member is fixed to the first maintenance door, and the blocking posture is provided when the first maintenance door is closed. And the second maintenance door is brought into contact with a part of the second maintenance door or a member interlocked with the second maintenance door while taking the allowable posture when the first maintenance door is opened and operated. It is configured to prevent the opening operation of the door. Therefore, when switching the second movable member for preventing the opening operation of the second maintenance door between the blocking posture and the allowable posture, the opening and closing operation of the first maintenance door can be used as it is. Further simplification of the linkage mechanism can be achieved.

In addition, with the configuration according to the sixth aspect, when the first movable member comes into contact with the second movable member, the first maintenance door is prevented from moving to the closed position. It is configured to block. That is, the first
Since the target to which the first movable member for preventing the maintenance door from moving to the closed position comes into contact is the second movable member itself for preventing the opening operation of the second maintenance door, the maintenance machine is used. The design change in the case of adding the type linkage mechanism can be minimized.
