Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Field of Industrial Application) The present invention relates to a storage case for storing a photosensitive recording medium used, for example, in an image recording device.

(Prior Art) In a conventional image recording device, a light-shielding image is formed on an intermediate sheet based on image information, and light is irradiated onto a light-sensitive pressure-sensitive recording paper through the intermediate sheet, thereby producing a light-sensitive pressure-sensitive recording. The paper is configured to be exposed to light.

(Problems to be Solved by the Invention) However, in the conventional apparatus described above, the intermediate sheet is conveyed by a simple roller, so the intermediate sheet is moved and the light-shielding image and the photosensitive pressure sensitive image are transported. There was a problem in that when the intermediate sheet and the photosensitive pressure sensitive recording paper were overlapped and exposed to light, a positional shift occurred between the intermediate sheet and the photosensitive pressure sensitive recording paper, resulting in color shift in the image formed on the photosensitive pressure sensitive recording paper. .

In order to solve these problems, when forming an intermediate image, positioning holes are drilled on the intermediate sheet, or positioning marks are placed on the intermediate sheet, which are read by a sensor and used to drive the conveyance rollers, etc. Although it is conceivable to add a device for controlling and accurately positioning, there is a problem that this makes the entire device complicated and expensive.

Another problem with the conventional apparatus is that it requires a space for extending the photosensitive and pressure sensitive recording paper along the intermediate sheet and a mechanism for conveying the photosensitive and pressure sensitive recording paper, making the entire apparatus complicated and large. There was a point.

゛ This invention was made in view of the above-mentioned problems, and its purpose is to easily align the intermediate sheet and the photosensitive and pressure-sensitive recording paper with a wheel-shaped configuration, and to To provide a storage case for light-sensitive and pressure-sensitive recording paper, which can reduce the exposure space of the pressure-sensitive recording paper and downsize the entire apparatus.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention has an opening for pulling out the photosensitive recording medium in the peripheral wall of the storage case body that stores the roll-shaped photosensitive recording medium. a guide member is provided on at least one side wall of the storage case to guide the pulled out photosensitive recording medium along the outer peripheral surface of the storage case so as to be rotatable relative to the storage case body; The guide member is provided with a holding means that fixes the photosensitive recording medium to the guide member when the guide member rotates in one direction, and releases it when the guide member rotates in the other direction.

(Function) Therefore, according to the storage case of the present invention, when the guide member rotates in one direction, the photosensitive recording medium pulled out from the storage case is fixed to the guide member by the holding member, and together with the guide member, the photosensitive recording medium is attached to the outer peripheral surface of the storage case. When it rotates in the other direction, it is released from the guide member and exposure is performed on the outer periphery of the storage case body.

A wire dot type impact head 11 is connected to the impact head 11 via a wire dot, and a translucent intermediate sheet 14 and an ink ribbon 15 are arranged so as to overlap between the impact head 11 and a platen 13 rotated by a motor 12. The light transmitted through each of the filters 7R17G and 7B of the three-color separation filter selectively arranged in the optical path is read by the COD image sensor 8, and the impact head 11 is operated outside the reading area to remove the ink ribbon 15.
Light-shielding images 16 are successively formed on the intermediate sheet 14 by the upper ink.

The intermediate sheet 14 is rewound from a take-up roller 18 rotated by a motor 17 and transported upward, and is sent between the platen 13 and the impact head 11 to be sent to an exposure device 22 and a storage case 41, which will be described later. After passing through the gap, the sheet is guided by a pair of guide rollers 19 and wound onto a winding roller 21 rotated by a motor 20.
