Abstract

A stacking apparatus includes: a cassette which accommodates a plurality of recording media in a superimposed manner; a mounting portion on which the cassette is mounted; a transportation path which is arranged at a downstream side in a direction in which the cassette is mounted on the mounting portion and on which the recording media are transported from the cassette mounted on the mounting portion; a stopper of which surface for regulating downstream side edges of the recording media regulates the side edges until the cassette is mounted on the mounting portion and of which surface for regulating the side edges of the recording media releases the regulation of the side edges with a rotational operation after the cassette is mounted on the mounting portion; and a slider which slides along a back surface of the regulating surface of the stopper for regulating the side edges.

Claims

1. A stacking apparatus comprising:

a cassette which accommodates a plurality of recording media in a superimposed manner;

a mounting portion on which the cassette is mounted;

a transportation path which is arranged at a downstream side in a direction in which the cassette is mounted on the mounting portion and on which the recording media are transported from the cassette mounted on the mounting portion;

a stopper of which surface for regulating downstream side edges of the recording media regulates the side edges until the cassette is mounted on the mounting portion and of which surface for regulating the side edges of the recording media releases the regulation of the side edges with a rotational operation after the cassette is mounted on the mounting portion; and

a slider which slides along a back surface of the regulating surface of the stopper for regulating the side edges.

2. The stacking apparatus according to claim 1,

wherein a first comb-tooth shape is provided on a back surface of the regulating surface of the stopper for regulating the side edges and a second comb-tooth shape which engages with the first comb-tooth shape is provided on a surface of the slider at a side opposed to the stopper.

3. The stacking apparatus according to claim 2,

wherein a viscous material is arranged between surfaces of the stopper and the slider, which are opposed to each other.

4. The stacking apparatus according to claim 3,

wherein the surface of the stopper for regulating the side edges is subjected to a high friction processing.

5. The stacking apparatus according to claim 4,

wherein the stopper is provided at a position corresponding to a center portion of the side edges in an extension direction of the side edges.

6. The stacking apparatus according to claim 5,

wherein a plurality of stoppers are provided so as to be parallel with the extension direction of the side edges.

7. A transportation apparatus comprising:

a cassette which accommodates a plurality of recording media in a superimposed manner;

a mounting portion on which the cassette is mounted;

a transportation path which is arranged at a downstream side in a direction in which the cassette is mounted on the mounting portion and on which the recording media are transported from the cassette mounted on the mounting portion;

a stopper of which surface for regulating downstream side edges of the recording media regulates the side edges until the cassette is mounted on the mounting portion and of which surface for regulating the side edges of the recording media releases the regulation of the side edges with a rotational operation after the cassette is mounted on the mounting portion; and

a slider which slides along a back surface of the regulating surface of the stopper for regulating the side edges; and

a transportation roller which transports the recording media transported from the stacking apparatus.

8. A recording apparatus comprising:

a cassette which accommodates a plurality of recording media in a superimposed manner;

a mounting portion on which the cassette is mounted;

a transportation path which is arranged at a downstream side in a direction in which the cassette is mounted on the mounting portion and on which the recording media are transported from the cassette mounted on the mounting portion;

a stopper of which surface for regulating downstream side edges of the recording media regulates the side edges until the cassette is mounted on the mounting portion and of which surface for regulating the side edges of the recording media releases the regulation of the side edges with a rotational operation after the cassette is mounted on the mounting portion;

a slider which slides along a back surface of the regulating surface of the stopper for regulating the side edges;

a transportation roller which transports the recording media transported from the stacking apparatus; and

a recording portion which performs a recording processing on the recording media transported by the transportation apparatus.
