Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is a light-sensitive room such as a photosensitive strip material cut into a strip shape and wound in a roll, for example, a microfilm, a microfilm for computer output, a film for computer typesetting. The present invention relates to a photosensitive band material container incorporated in an exposure apparatus.

[Conventional technology]

Conventionally, as a container that fulfills such an object, U.S. Patent No. 4,
There is one disclosed in the specification of 272,035. This is an opening for accommodating a photosensitive strip (hereinafter referred to as a roll) wound in a roll shape as shown in FIG. 5 and a slot for accommodating the roll 50 to take out the leader 55 thereof. A main body 51 having a roll 54, a cover 52 for closing the opening of the main body 51 after accommodating the roll 50, and a closing member 53 for closing the slot 54 in cooperation with a protrusion 71 provided on the cover 52.

Further, the main body 51 and the cover 52 are fixed to each other by fitting the edge portions 18 protruding outward from the surfaces of the four side walls of the main body 51 and the protrusions 72 provided on the cover 52.

FIG. 6 is a cross-sectional view of a normal portion of the edge portion, and FIG. 7 is a sectional view of a fitting portion.

[Problems to be solved by the invention]

An important function in such a container is that the length resistance for pulling out the photosensitive material strip from the slot portion is small and the light does not enter the inside of the container.

In general, the light shielding of the slot portion is constituted by sticking a velvet ribbon or a flexible plastic foam on the facing surfaces of the side wall and the shielding member constituting the slot portion. In order to maintain both the pull-out resistance and the light-shielding property in a well-balanced region, the gap between the side wall and the closing member must be accurately and firmly maintained.

The prior art discloses a device for facilitating insertion of the leader part, but does not disclose any special technique for maintaining these gaps. For example, there is play in the fitting part between the cover member and the side wall and the closing member. Also, although it is possible to perform positioning to give the maximum slot width in the closed state by the projection provided on the cover, if the closing member is pulled out to the side wall side, it will be narrower than the original designed value and the pullout resistance will be large. Can happen.

The present invention intends to provide a photosensitive strip material container which keeps an appropriate pull-out resistance with stable light-shielding property by adding a new device to this point.

[Means to try to solve problems]

The present invention has constructed the following means to solve these problems.

The closing member is fixed by providing the closing member with a fin perpendicular to the slot surface, providing a surrounding wall inside the main body, and fitting the surrounding wall so as to surround the fin.

By providing a protrusion inside the groove that fits into the side wall of the main body of the cover, the cover and the main body can be fixed without play at the joint, and the slot width can be kept stable.

Hereinafter, these detailed examples will be described in detail.

FIG. 1 is an overall view of a preferred embodiment of the present invention, in which a basic component is a main body 1 having a slot 4 as in the prior art.
The cover 2 and the closing member 3 are arranged so that the closing member is fitted inside the main body.

Next, FIG. 2 shows a method of fixing the closing member of the first invention.

FIG. 2 (a) is an enlarged view of the closing member 3, which has fins 31 and 32 having a substantially L-shaped cross section and being perpendicular to the surface 30 forming the slot. The shape of the fins 31 and 32 is somewhat trapezoidal, and the relationship between the lengths of the two sides parallel to the slot surface is f> f 'and l>l'.

On the other hand, FIG. 2B shows the surrounding wall 6 provided on the main body. The surrounding wall 6 is provided with a contact wall 61, but this is not necessarily a requirement of the present invention. The surrounding wall 6 has a dimensional relationship between the back side and the opening side.
f0> f0 'and f0' is slightly f0 '<with respect to f'of the closing member.
f '. The relationship between f0 'and f may be f0> f.

FIG. 2C shows a state in which the closing member 3 is fitted to the surrounding wall 6. The fins 31, when inserting the closing member 3 into the surrounding wall,
It is possible to guarantee the maximum value of the slot gap t after fitting by having the surfaces 311 and 321 of 32 along the abutment wall 61 (if the abutment wall 61 is not provided, it is brought into contact with the inner wall 62 of the surrounding wall 6). Since the fins have a trapezoidal shape, the fins are automatically held by the surrounding wall when the fins are inserted along the surrounding wall. By selecting the relationship appropriately, a sufficiently favorable state can be obtained. That is, the closing member is prevented from being pulled out and shifted to the slot surface side, and the t value is always fixed. With this, the first object of the invention was achieved.

Although the hitting wall 61 is not necessarily a requirement for designing, the operability of the present invention can be improved by providing an inclination.

FIG. 3 is an enlarged view of a portion 21 corresponding to the slot portion of the cover 2, and has an outer edge 22 and an inner edge 23 for fitting the side wall 11 constituting the slot portion of the main body.

Reference numeral 24 is a protrusion provided on the inner edge 23, and FIG. 4 is an enlarged view of the protrusion and a modification thereof. Normally, when the cover is closed on the main body, it is necessary to fit all four sides for light shielding, and for that reason, play is required to the extent that light shielding is not impaired.

According to the present invention, the side wall is fixed while ensuring the play required for fitting the main body and the cover, and the side wall of the slot is formed by providing the protrusion 24 on the edge of the mating cover as shown in FIG. It is fixed without playing.

Since the protrusion 24 has a shape as shown in the enlarged view, the tip portion 12 of the side wall 11 shown in FIG. It can be completely fixed without playing.

With this, the second purpose of invention was achieved.

In the prior art, when the leader portion of the photosensitive strip is inserted, the closing member is opened in a V shape to provide ease of insertion. However, even in the present invention, the leader portion is inserted with the closing member inserted halfway. If it is inserted, its easiness is secured, and then, if the closing member is pushed in to the end, the originally intended function can be fulfilled.

[Effect of device]

By implementing the present invention, it is possible to provide a bright chamber loading container that stably maintains the balance between the drawing resistance and the light shielding property.
