An image recording apparatus has been proposed in which an image-receiving material is brought into close contact with a heat-developable photosensitive material after heat development, and the image is sent to a transfer section, where the image is thermally transferred to the image-receiving material.

As a method for supplying the image-receiving material, there are a method in which the image-receiving material formed in a sheet shape is supplied in a piled state, or a method in which the image-receiving material formed in a sheet shape is supplied after being wound into a roll shape and then cut into a sheet shape. Considering the storability of the image-receiving material,
2. Description of the Related Art A configuration in which an image receiving material wound into a roll is stored in a magazine is preferable, and an image recording apparatus has been proposed in which the magazine is loaded into an image receiving material supply section.

[Problem to be solved by the invention]

When recording an image, an image may be recorded on a single independent image-receiving material, depending on the application, without using a roll-shaped image-receiving material. For example, to record an image on an image-receiving material that is used infrequently, it is more convenient to use an image-receiving material that has been cut into sheets in advance than an image-receiving material that is wound into a roll. Therefore, an image recording apparatus equipped with a manual feeding section has also been proposed so that image-receiving materials can be fed one by one manually.

However, by providing a manual feeding section in addition to the rolled image-receiving material feeding section, two types of feeding mechanisms and conveyance paths are required, resulting in a problem that the configuration of the image recording apparatus becomes complicated. .

Therefore, an object of the present invention is to solve the above-mentioned problems, and even in an apparatus for feeding roll-shaped image recording material,
It is an object of the present invention to provide an image recording material supply device capable of supplying a single sheet of image recording material without requiring any other supply means or conveyance path.

[Means and Effects for Solving the Problems] The above object of the present invention is to provide an image recording material supplying device having a magazine loading section into which a magazine containing a roll of image recording material is loaded. The loading section includes a groove that holds a rear end of the recording material in the transport direction, and a regulating member that restricts the front edge and side edge of the monolayer image recording material whose rear end is held in the liquid groove in the transport direction. This is achieved by an image recording material supply device consisting of:

That is, by having the magazine loading section configured to position and hold the single sheet image recording material, it is possible to supply the single sheet image recording material without providing a manual feeding mechanism or other conveyance path. Further, when the magazine is loaded, the image recording material in the magazine can be supplied, and various types of image recording materials can be supplied without complicating the configuration of the image recording apparatus.

The image recording materials used in the present invention include the following.

For example, Japanese Patent Application Laid-open No. 57-1798 related to the applicant's application

This photosensitive material has a synthetic polymer resin wall capsule containing a vinyl compound, a photopolymerization initiator, and a colorant precursor supported on a support.

Another example is a type in which a latent image generated by imagewise exposure is subjected to preliminary heat development or wet development, and then the image-receiving material is overlapped with pressure to obtain a visible image. Examples of such materials include Japanese Unexamined Patent Publication No. 1983-1999 filed by the present applicant.
There is one disclosed in Japanese Patent No. 278849. The material disclosed in JP-A No. 61-278849 is a material in which a color image-forming substance is transferred to an image-receiving material having an image-receiving layer after thermal development to obtain an image on the image-receiving material. is coated with at least a photosensitive silver halide, a reducing agent, a polymerizable compound, and a color image-forming substance, and at least the polymerizable compound and the color image-forming substance are encapsulated in the same microcapsule.

Another example is a so-called heat-developable photosensitive material in which an image obtained by thermal development is transferred to an image-receiving material by heating. This photosensitive material is one in which a mobile dye is released imagewise by heating, and the mobile dye is transferred to an image receiving material (dye fixing material) having a mordant using a solvent such as water; Transfer to the image receiving material is performed using a high boiling point organic solvent, transfer is performed to the image receiving material using a hydrophilic hot solvent contained in the image receiving material, or
It is known that the mobile dye is thermally diffusible or sublimable and can be transferred to a dye-receiving material such as a support. Specifically, U.S. Pat. ,4
