As an issue.

[0006]

According to the first aspect of the present invention, a photographic light-sensitive material on which an image is recorded is installed on a scanning unit.

The photographic photosensitive material is held between a mask set on a document table and a pressure plate for pressing the mask. The moving means reciprocates the base on the base, and causes the line sensor of the reading unit to read the image information recorded on the photographic material.

Further, since the mask is provided with a conveying means so that the photographic light-sensitive material can be frame-advanced on the original table, it is not necessary to open the pressure-bonding plate to carry the frame.

According to the second aspect of the present invention, the holding means holding the photographic light-sensitive material is mounted on a document table. The platen moves onto the scanning unit, and causes the line sensor of the reading unit to read the image information recorded on the photographic material.

The holding means is provided with a second conveying means for conveying the photographic material, so that the photographic material can be fed on a document table. Driving force is transmitted to the second transport means from the first transport means provided on the document table. When the document table moves to a predetermined position, a driving force is transmitted to the first conveying unit from a driving source provided on the base table.

According to the third aspect of the present invention, the first transporting means has an impact buffering means for buffering an impact force with the drive source when the document table moves to a predetermined position. For this reason, the drive source and the first transport unit are not easily damaged by the impact force.

According to the fourth aspect of the present invention, the first transport means is rotatably attached to the support member fixed to the document table and the support member, and is rotated from the driving source when the document table is moved to a predetermined position. A first rotational force transmitting member to which a force is applied, and a shock absorbing means for supporting the first rotational force transmitting member so as to be slidable in the moving direction of the document table;
Urging means for urging the first torque transmitting member toward the drive source;
Wherein the second conveying means is provided with a driven roller provided on the holding means, a driving roller provided on the holding means for nipping and conveying the photographic photosensitive material between the driven roller, and a driving roller. A second torque transmitting member provided on the shaft and to which a torque is applied from the first torque transmitting member.

In this configuration, the first torque transmitting member is rotatably supported by the support portion of the support member fixed to the document table so as to be rotatable and slidable in the moving direction of the document table. Also,
The first rotational force transmitting member is urged toward the drive source by the urging means, and slides when contacting the drive source to buffer the impact force. In addition, the first torque transmitting member receives the torque from the drive source while being in contact with the drive source.

On the other hand, the driven roller and the driving roller of the holding means mounted on the document table sandwich and transport the photographic material. A second rotational force transmitting member is provided on the shaft of the drive roller, and rotational force is applied from the first rotational force transmitting member.
Thereby, the torque is transmitted in the order of the drive source, the first torque transmitting member, and the second torque transmitting member.

According to the fifth aspect of the present invention, the holding means without the second conveying means, for example, a mount mask can be attached to and detached from the document table.

According to the sixth aspect of the present invention, when the document table moves to a predetermined position, the document table is transferred to a transport unit provided in the holding means.
The driving force is directly transmitted from a driving source provided on the base, and the photographic material is conveyed.

In the invention according to claim 7, the periphery of the slit provided on the base and corresponding to the scanning section is closed by a cover, and the slit is covered by a light-transmitting flat plate. For this reason, there is no possibility that foreign matter is accidentally dropped on the scanning unit.
