JPS60205438A - Film magazine device for x-ray snapshot device - Google Patents

Abstract

PURPOSE:To prohibit drawing out of a film magazine while a cap is held open by providing an automatic locking mechanism which locks the film magazine in such a way that the magazine cannot be detached from the inside of a snapshot device while the magazine is held loaded therein and when the cap thereof is opened. CONSTITUTION:A lever 3c is still in a halt state and a magazine 2 is not locked as there is space (s) between the lever and a stopper 2f in the state just before loading of a magazine 2 into a housing 1. When the magazine 2 is fully loaded into the housing 1 from this state, the tip of the pin 2g contacts the other end of the lever 3c and the lever 3c turns counterclockwise to eliminate the space (s). If, therefore, a cap plate 2b is opened by drawing a shaft 2c from this state, a stopper 2f engages with one end of the lever 3c to the state that the magazine 2 cannot be detached even if the user tries to pull the same from the inside of the housing 1 by pulling a handle 2e, i.e., the locked state.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention provides a film magazine comprising an This invention relates to a film magazine device for an X-ray photographic device, in which f is configured to be detachably attached to a photographic device with a loading port area.

[Background of the invention]

Conventional film magazine devices of this type have been configured so that when a film magazine is loaded into the X@speed copy device, it is automatically locked and cannot be removed (pulled out).
The configuration was such that the lock could be manually released.

For this reason, there was a drawback that a film operator who made an erroneous operation could release the lock and pull out the film magazine while the cover was open, causing the film in the storage box to become exposed to light. .

[Purpose of the invention]

The present invention has been developed to eliminate the above-mentioned drawbacks, and the film magazine cannot be removed (extracted) from the X@speed copying device when the lid of the X-ray film storage box is open, thereby preventing erroneous operation. It is an object of the present invention to provide a film magazine device for an X-ray photographic device, which prevents exposure of the film due to exposure to light caused by, for example, exposure of the film.

[Summary of the invention]

The present invention provides an Xll1! in which a film magazine comprising an X-ray film storage box, a lid of the storage box, and a shaft for opening and closing the lid is configured to be removably attached to the magazine loading slot of the X@speed-photography device. In the film magazine device for a quick-shooting device, when the film magazine is loaded in the quick-shooting device and the lid is opened by a shaft, the film magazine is locked so that it cannot be removed from the inside of the quick-shooting device. An automatic locking mechanism is provided to prevent the film magazine from being pulled out while the lid is open.

[Embodiments of the invention]

The present invention will be described in detail below with reference to FIGS. 1 to 5. Fig. 1 is a sectional view showing the loading part of an embodiment of the film magazine device for an X-ray speed copying apparatus according to the present invention, Fig. 2 is a sectional view on the right side of Fig. 1, and Fig. 3 is a dashed line in Fig. 1. These are plan views showing the film magazine taken out. In these figures, 1 is the housing of the X-ray copying device, and 72o formed by 1aViEff body IK is a non-loading port. Note that an insertion hole 1b for a later-described bottle, which constitutes an automatic locking mechanism, is bored in the upper part of the loading port 1a of the housing 1.

2 is a film magazine that can be attached and detached into the housing 1 as shown by the arrow in the loading port 1a, and X#i! The main components include a film storage box 2a, a lid plate 2b that opens and closes the rear upper surface of the storage box 2a, and a shaft 2c that opens and closes by operating the lid plate 2b in the direction of the arrow in FIG. The magazine 2 is provided with a front channel 2d which also serves to prevent the magazine 2 from falling into the housing 1 from the loading port 1a, and a handle 2e attached to the front panel 2d.

Also, at the rear end of the shaft 2c of this magazine 2 is a hook-shaped stone z! 2f is provided, and the front and side panels are 2d.
A bottle 2g is disposed on the back side of the bottle 2g, facing the bottle 2f at a predetermined distance. Note that the mailbox 2c is foldable at the middle bin portion 2h.

3 is the above stone a4?2f and bottle 2g, and ma is non-2
The locking mechanism main body constituting the automatic locking mechanism includes a support plate 3ab shaft 3b, a lever 3c, a tension spring 3d, and a spring hook 3@ above the back surface 91+1 of the magganon mounting opening 1a of the housing 1. It becomes. In the case of Jin, the shaft 3b is the lever 3c'kf'! , rotatably supported at the center,
Further, the spring 3d is provided between one end of the lever 3c and the pin 3e, and applies a rotational force to the lever 3c in the clockwise direction in FIG. 1. In the rest state, the lever 3c
Since the other end is in contact with the back surface of the casing 1, the state shown in FIG. 1 can be maintained. The positional relationship between the lever 3c, the stopper 2f and the bottle 2g is shown in FIG. 4 and 8F4.
As shown in Figure 5. That is, when the ↓ sea urchin lever 3c shown in FIG. 4 is in the rest state, a gap 8 is created,
Stotsu I when operating shaft 2c? One end of the lever 3c is not located on the trajectory of the tip of the lever 2f, and the tip of the bottle 2g comes into contact with the other end of the lever 3c shown in FIG. When the lever 3c is rotated counterclockwise, one end of the lever 3c is located on the trajectory, and when the shaft 2cf is pulled, the stone/412f is set to engage with the one end of the lever 3c.

Next, the operation of the above-mentioned device of the present invention will be described. Figure 4 shows the state of the magazine 2 just before it is loaded into the housing l.
In this state, the lever 3c is still at rest, and the gap S is created between it and the stopper 2f, so the magazine 2
Hasn't been a rock field. When the magazine 2 is completely loaded into the housing 1 from this state, the tip of the bottle 2g comes into contact with the other end of the lever 3c, the lever 3c rotates counterclockwise, and the gap 8 disappears. Therefore, from this state the shirt) 2c
When the cover plate 2b is opened by pulling the handle 26, the stopper 2f engages with one end of the lever 3c as shown in FIG. In other words, it becomes a locked state.

〔Effect of the invention〕

In accordance with the above-mentioned method, the present invention locks the film magazine so that it cannot be removed from the X-ray copying apparatus when a film magazine is loaded in the X-ray copying apparatus and its lid is opened by the shaft. Equipped with an automatic locking mechanism,
It is not possible for the film operator to pull out the film cartridge from inside the quick-shooting device (2) with the lid open, which has the effect of preventing exposure of the film due to erroneous operation.
