2. Description of the Related Art Conventionally, in order to appreciate a developed photographic film, a developed projector such as a slide projector for displaying an image on a screen or an image display device for displaying an image using a television receiver as a display monitor. Film viewing equipment is used. Since these viewing devices are generally configured to set a slide film framed into each frame or the film itself cut into several frames, the film is used when the film is used or stored. Inconvenient to handle. Therefore, in order to make it easy to handle the developed photographic film like a video tape cassette, for example, as in the case of a film cartridge for shooting, the film is wrapped around the winding shaft and stored in the cartridge case. It is conceivable to use the film cartridge in a dedicated viewing device.

In this case, the cartridge has the advantage of simplifying the structure that, unlike the film cartridge for photographing, the light shielding function is unnecessary because the film to be stored has already been developed. Since the viewing is repeated many times, it is necessary to have sufficient durability so that it can be used repeatedly.

Therefore, the technical problem to be solved by the present invention is to provide a film cartridge having excellent durability for a developed film, and further, it is suitable for displaying images by using this novel cartridge. It is to provide a device.

[0005]

MEANS FOR SOLVING THE PROBLEMS, ACTIONS AND EFFECTS The developed film cartridge according to the present invention is constructed as follows in order to solve the above technical problems. That is, this cartridge has a developed film, a film winding shaft for winding the film, a tubular wall and both end walls, and a film insertion slit is formed in the tubular wall and the film is formed on both end walls. And a cartridge case in which a bearing portion for the winding shaft is formed, and the bearing portion is formed of a hole having a diameter larger than the outer diameter of the film winding shaft located in the bearing portion.

This cartridge has a cartridge loading section, a feeding mechanism for feeding the film of the cartridge loaded in the loading section, and an image display for displaying the image set at the display position by the feeding mechanism on the screen. A developed film viewing device including a mechanism, wherein a cartridge loading section engages a positioning means for positioning the cartridge case and a winding shaft of the cartridge in which the cartridge case is positioned by the positioning means. It is used in an apparatus that has a support shaft that supports the shaft substantially at the center of the bearing and that drives the winding shaft to rotate, and that is connected to a film feeding mechanism.

In the above structure, when the film cartridge is loaded in the cartridge loading section of the viewing device,
The cartridge case is positioned by the positioning means, and at the same time, the take-up shaft of the cartridge is supported by the support shaft at a substantially central position of the bearing portion of the cartridge case. Since the inner diameter of the bearing portion is formed to be larger than the outer diameter of the winding shaft, the winding shaft does not come into contact with the bearing portion when being rotationally driven by the feeding mechanism.
Then, when the film is fed and a predetermined frame is set at the display position, the image is displayed on the screen such as a screen or a monitor display by the image display mechanism.

In a cartridge for photographing, the winding shaft is normally held in contact with the bearing hole of the cartridge case, and therefore wear occurs when the winding shaft is repeatedly rotated, but the cartridge is viewed as described above. The wear can be prevented by configuring the bearing portion and the winding shaft to be in non-contact with each other when loaded in the apparatus. Therefore, durability against repeated use is improved. Further, in a cartridge for photographing, a rubbing noise is generated when the winding shaft is rotated, but in this cartridge, the rubbing noise can be prevented because the bearing portion and the winding shaft are not in contact with each other.

Further, in the cartridge having the above construction, the film insertion slit is formed so that the width dimension thereof is wider than the thickness dimension of the film, and the guide portions for guiding the edge portion of the film are provided at both ends thereof. Is preferred.
According to this structure, when the film is taken in and out of the cartridge case, the edge of the film is guided by the guide portion, and it is possible to prevent the central image forming region excluding the film edge from contacting the case. . Therefore, the film can be taken in and out smoothly, and the image forming area can be prevented from being damaged.

Further, in the above structure, it is preferable to provide a lid member for opening and closing the film insertion slit.
According to this structure, when the image is viewed, the cover member can be opened and used to smoothly take the film in and out, and by closing the cover member during storage, deterioration of the film can be prevented. It can be prevented. In addition,
By configuring the viewing device and the cartridge so that the lid member is automatically opened when the cartridge is loaded in the viewing device, it is possible to prevent the user from being bothered to open and close the lid.

Further, in the above structure, it is preferable to provide at least a pair of roller members near the film insertion slit to guide the feeding of the developed film by sandwiching the developed film from both sides. According to this structure, the film can be taken in and out more smoothly with respect to the cartridge case.

Further, in the above construction, the film winding shaft is provided with a holding portion for inserting and holding the end portion of the developed film inside the winding shaft, and the holding portion is provided with the end portion inside the holding portion. It is preferable that the winding portion is bent at an obtuse angle from the terminal end portion of the film when the film is wound around the winding shaft by being inserted into the film. According to this structure, the film can be held more firmly than, for example, the end portion of the film is bonded to the take-up shaft, and the end portion of the film is bent at an obtuse angle rather than an acute angle. It is possible to prevent the film from deteriorating even when the film is repeatedly taken in and out.

Further, it is preferable that the viewing device is provided with at least a pair of guide rollers for feeding the film by sandwiching the film from both sides in the vicinity of the film insertion slit of the cartridge loaded in the cartridge loading section. With such a structure of the viewing device, the position where the film passes through the slit of the cartridge case is constant, so that the film can be prevented from coming into contact with the cartridge case.

Further, according to the present invention, instead of forming the bearing portion with a hole having an inner diameter larger than the outer diameter of the film winding shaft, a film having a bearing member for supporting the film winding shaft is provided in the bearing portion. A cartridge is provided. As the bearing member, for example, one having a rolling element such as a ball bearing or a needle bearing is preferably used.

Even with this structure, it is possible to prevent the take-up shaft and the cartridge case from slidingly contacting and wearing. When the bearing is provided as described above, it is not necessary to separately position the cartridge case and the winding shaft on the viewing device side, and only the position of the winding shaft may be fixed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The developed film cartridge and its viewing device according to the embodiment of the present invention shown in FIGS. 1 to 26 will be described in detail below.

First, the cartridge according to the first embodiment shown in FIGS. 1 to 5 will be described. 1 is a perspective view of this cartridge, FIG. 2 is a perspective view of a state in which a film is wound around a winding shaft of the cartridge, FIG. 3 is a longitudinal sectional view of the cartridge, FIG. 4 is a partially cutaway plan view of the cartridge, and FIG. It is a longitudinal cross-sectional view of a state in which the cartridge is loaded in the ornamental device.

In the figure, 10 is a cartridge case having a cylindrical wall 10a and both end walls 10b. A slit 11 for inserting a film is formed in a cylindrical wall 10a of the cartridge case 10, and a hole 10c is formed in both end walls 10b as a bearing portion for receiving both end portions 12a, 12b of a film winding shaft 12. . This bearing hole 10c
Is formed with a diameter larger than the outer diameter of both ends 12a, 12b of the winding shaft 12. In the cartridge for photography, a telem is provided in the slit for inserting the film in order to prevent light from entering the case, but the cartridge of this embodiment stores the developed film and has a light-shielding property. Is not particularly important, so no telemp is provided.

The film winding shaft 12 has one end 1
2a has an engaging claw 12d that engages with a fork 43 of an ornamental device (details will be described later) to rotate the winding shaft 12, and the other end 12b has a rotation of the winding shaft 12. It has a center hole 12c into which a center pin 42 for positioning the center is inserted. The film 20 is wound around the winding shaft 12 so that the edges are aligned along the inner surfaces of the flanges 21a and 21b, and is housed in the cartridge case 10. The tip 2 of this film
0a is obliquely cut so as to easily pass through the slit 11.

Reference numerals 40 and 41 respectively denote cartridge chamber constituent members of the ornamental device. The fork 43 described above is formed integrally with the driver gear 44, and transmits the driving force from a film feeding mechanism (not shown) to rotate the winding shaft 12 to feed the film. Reference numeral 45 denotes a spring for positioning the cartridge case 10 which is provided on the lower surface and the side surface of the cartridge chamber, and presses the cartridge case 10 against the facing surface of each spring 45 and holds it at that position. At this time, each part is dimensioned so that the winding shaft 12 positioned on the center pin 42 and the fork 43 is located substantially at the center of the bearing hole 10c.

Since this film cartridge has a gap between both end portions 12a and 12b of the winding shaft 12 and the bearing hole 10c, the winding shaft 12 is movable as a unit with respect to the cartridge case 10. However, if the cartridge is loaded into the viewing device, cartridge case 1
0 and the take-up shaft 12 are positioned separately, so that the take-up shaft 12 has a bearing hole 10c by allowing a clearance between them to be larger than the positioning accuracy of both members.
It can be rotationally driven in a non-contact state.

Next, a slide projector used as an ornamental device for this cartridge will be described. FIG. 6 is a perspective view of this slide projector, and FIG.
Is a perspective view of the slide projector with a cartridge loading lid opened, FIG. 8 is a view showing an optical configuration of the slide projector, and FIG. 9 is a configuration diagram of a film feeding mechanism in the slide projector.

6 and 7, reference numeral 100 is a slide projector main body, 102 is a cartridge loading lid, 104 is a projection lens, 106 is a cartridge used in the slide projector 100, and 108 is a film guide. Further, in FIG. 8, 110a, 11
0b is a screen frame that also serves as a film passage guide and determines the frame of the image, 112 is a spool for winding the film, 114 is a light source lamp, 116 is a reflecting umbrella for condensing, and 118 is a condenser lens. The mechanism is configured. In FIG. 9, 120 is a film pulled out from the cartridge 106, 122 is a perforation provided on the film 120 to determine the position of the screen, 124 is a film drive mechanism, 126
Is the first output gear, 128a is the feed drive planetary gear, 1
28b is a rewinding drive planetary gear, 130 is a fork drive gear, 132 is a fork drive mechanism, 134 is a fork engaging with the take-up shaft 106a of the cartridge 106, 1
36 is a second output gear, 138 is a hoisting drive planetary gear,
Reference numeral 140 is a spool drive gear, 142 is a spool drive mechanism, 144 is a photo reflector for detecting the moving state of the perforation 122, 146 is a magnetic head for reading and writing magnetic information from and to a magnetic surface provided on the film, and 148 is an apparatus. It is a control circuit that controls the entire operation.

In this slide projector 100, after the cartridge 106 is loaded, the control circuit 14
8 outputs a fork drive signal to the film drive mechanism 124, and the first output gear 126 rotates counterclockwise in the figure in accordance with this signal. Therefore, the feed drive planetary gear 128 a meshes with the fork drive gear 130, and the rotation thereof is transmitted from the fork drive mechanism 132 to the winding shaft 106 a of the cartridge 106 via the fork 134, and the film 120 is fed from the cartridge 106. The film 120 sent out is the film guide 1
It advances from 08 through the screen frames 110a and 110b, and winds around the spool 112.

At this time, the second output gear 136 rotates clockwise based on the output signal from the control circuit 148, and the rotation of the second output gear 136 passes through the winding drive planetary gear 138, the spool drive gear 140, and the spool drive mechanism 142. Is transmitted to the spool 112. Therefore, the film 120 is wound and driven by the spool 112 after being wound around the spool 112.

The film 120 has a perforation 1
The movement of the photo reflector 144 is detected by the change in the signal of the photo reflector 144 due to the passage of 22. Further, when the film 120 is fed, the magnetic information is read by the magnetic head 146 and a predetermined frame is detected. Therefore, when it is determined that the predetermined frame is set at the display position based on the magnetic information read by the magnetic head 146, the film driving mechanism 124 is stopped and the film is illuminated with the light from the light source lamp 114, and An image can be projected on a screen (not shown) by the projection lens 104 by the transmitted light.

When the viewing is completed, a signal is sent from the control circuit 148 to the film driving mechanism 124 so that the first output gear 126 rotates clockwise. Therefore, the rotation is transmitted from the rewinding drive planetary gear 128b to the fork drive gear 130, and the fork drive mechanism 13
It is transmitted from 2 to the winding shaft 106a via the fork 134. As a result, the film is wound on the winding shaft 106a, and when the winding is completed, the lid 102 can be opened and the cartridge can be taken out.

When viewing an image recorded on the film 120, the film 120 is usually forwarded frame by frame, and rewinding is performed after the last frame is completed. Accordingly, the film drive mechanism 124 is controlled by the control circuit 148 to enable reverse feed during viewing and fast forward in both forward and reverse directions for searching for a predetermined frame. Therefore, although the winding shaft 12 frequently rotates in both directions with respect to the cartridge case 10, as described above, the winding shaft 1
Since the shaft 2 and the bearing hole 10c are not in contact with each other, the shaft 12 and the bearing hole 10c are not worn. Therefore, the film cartridge of this embodiment does not suffer from deterioration in durability due to abrasion.

Incidentally, this slide projector 100
In the above, the pair of film guides 108 is provided in the vicinity of the film insertion slit of the cartridge 106, but a guide roller may be provided instead. By doing so, the film can be fed more smoothly.
