Description

DETAILED DESCRIPTION OF THE INVENTION << Industrial Application Field >> The present invention relates to a film magazine supporting device for supporting a film magazine mounted from above at a film carry-in port of an image recording apparatus.

<< Prior Art >> Generally, a film magazine of this type containing a roll film is mounted in an image recording apparatus in a bright room.

Then, the conventional film magazine is configured, for example, as shown in FIG. 6 and mounted on the image recording apparatus as shown in FIG.

That is, the film magazine 101 includes a film holder 110 that holds the roll film 5 in a light-tight magazine box 102. This film holder 110
Is a bearing device 1 in which both ends of the spool 6 for roll film 5 are held by flange members 112, and both ends of a spool shaft 111 of the film holder 110 are provided on both side plates 103.
We support in 08.

The roll film magazine 101 is detachably mounted on a film magazine cradle 114 provided in a film carry-in section of the image recording apparatus, and a film transport roller 118 provided in the image recording apparatus causes the roll film magazine 101 to be held in a film holder. The roll film 5 is conveyed from the spool 6 held by 110 into the image recording apparatus.

<< Problems to be Solved by the Invention >> However, the above-mentioned conventional example has a problem that meandering occurs when the roll film is conveyed.

The reason is that the spool shaft 111 of the film holder 110 is
Are supported by bearings 108 in the magazine box 102, and when the film magazine 101 is placed on the magazine receiving stand 114, the axis line between the spool shaft 111 and the pair of film transport rollers 118 for transporting the film. It is not always possible to maintain the parallelism of P with high accuracy.

That is, since the support for the spool shaft 111 and the support for the film transport roller 118 are formed as separate parts,
The accuracy of the assembling of the pedestal 114 for the magazine, the distortion of the shape of the magazine box 102, the assembling of the bearing member 108 in the magazine box 102, etc. affects the parallelism between the spool shaft 111 and the film transport roller 118. Therefore, complicated work is required for adjustment such as assembling, and it is extremely difficult to maintain this parallelism.

It is an object of the present invention to provide a film magazine supporting device which prevents the film from meandering when the roll film is conveyed from the film magazine into the image recording device.

<Means for Solving the Problem> In order to achieve the above object, the present invention provides a film magazine supporting device for supporting a film magazine mounted from above at a position of a film carry-in port of an image recording device, A pedestal provided on the upper side of the recording device to mount the film magazine, and provided on both sides of the film carry-in port, support a shaft of a roll film housed in the film magazine outside the image recording device. A pair of support members each having a bearing groove and supporting both ends of a pair of film transport rollers in parallel with the axis of the roll film in the image recording apparatus.

<Operation> When the film magazine is placed on the pedestal provided on the upper side of the image recording apparatus, the shafts of the roll film stored in the film magazine are provided on a pair of support members provided on both sides of the film carry-in port. Is supported by the bearing groove. At this time, in the image recording apparatus, the pair of support members support both ends of the pair of film transport rollers in parallel with the axis of the roll film. Therefore, since the shaft of the roll film and the film conveying roller are supported in parallel by the pair of supporting members, the meandering of the film does not occur when the roll film is conveyed from the film magazine into the image recording apparatus.

<< Embodiment >> FIGS. 1 to 3 show a first embodiment of the present invention. FIG. 1 is a longitudinal sectional view showing a supporting structure of a film magazine, and FIG. 2 is II-II of FIG. FIG. 3 is a perspective view of a main part, which is a vertical cross-sectional side view.

In these drawings, reference numeral 1 indicates the entire film magazine, and the film magazine 1 includes a film holder 10 in a light-tight magazine box 2. The film holder 10 holds both ends of the spool 6 of the roll film 5 with a pair of flange members 12, 12, and the spool shaft 11 of the film holder 10 has both ends on both side plates 3, 3 of the magazine box 2. It is extended out of the film magazine 1 through the through holes 4 and 4.

The film magazine 1 is provided with a cradle 14 for the film magazine, which is provided above the film carry-in section of the image recording apparatus.
In the state in which the spool shaft 11 is mounted on, the both ends of the spool shaft 11 are directly supported by the pair of spool shaft support plates 16 provided on both sides of the film carry-in port of the film carry-in unit.

As shown in FIG. 3, the magazine box 2 is formed in two pieces so as to divide the insertion hole 4 of the spool shaft into two, and one lid 2a is opened to hold the roll film 5. It is attached to the film holder 10.

Further, the portion of the spool shaft corresponding to the insertion hole 4 is processed to have a small diameter as shown in the drawing, and prevents light from entering the film magazine 1 through the insertion hole 4.

The spool shaft support plate 16 supports both ends of a pair of film transport rollers 18 for transporting the film 5 from the film magazine 1 in the image recording apparatus, and a bearing groove 17 is provided at the upper end thereof. Spool shaft 11 with bearing groove 17
The end portion 11a is supported via a bearing sleeve 13. The pair of bearing grooves 17, 17 has a pair of film transport rollers 18 whose axes convey the film 5.
Is formed so as to be parallel to the axis line of the bearing groove 17
When the spool shaft 11 is supported by
And the axis of the pair of film transport rollers 18 are parallel to each other.

In FIG. 2, reference numeral 7 is a guide plate for conveying the roll film 5, and reference numeral 15 is a sensor for detecting whether or not the film magazine 1 is correctly placed and mounted on the cradle 14 for the film magazine.

FIG. 4 is a vertical cross-sectional view of the essential parts showing a second embodiment of the present invention.

This embodiment is different from the first embodiment in that the magazine box 2 has covers 2A, 2A for covering both ends of the spool shaft 11, the appearance is adjusted, and the light tightness is further improved. .

FIG. 5 is a vertical cross-sectional view of the essential parts showing a third embodiment of the present invention.

In this embodiment, when mounting the film holder 10, both ends of the spool shaft 11 are attached to both side plates 3 of the magazine box 2.
It is supported by the shaft supporting members 8 and 8 provided in 3. Then, the insertion holes 20, 20 of the spool shaft support plates 16, 16 are opened in the bottom wall 2b of the magazine box 2 and closed with the closing lids 21, 21. When the film magazine 1 is placed on the pedestal (not shown) for the film magazine, the spool shaft support plate 16
Closes and pushes the lid 21 open to project into the magazine box 2 and supports both ends of the spool shaft 11.

<< Advantages of Invention >> As described above, according to this invention, the shaft of the roll film and the film transport roller are supported in parallel by the pair of support members provided on both sides of the film carry-in port of the image recording apparatus. With such a simple configuration, it is possible to prevent the meandering of the film that occurs when the roll film is conveyed from the film magazine to the image recording apparatus.
