The swingable member includes a slide guide surface configured to come into sliding contact with a slide surface of the media cassette upon the insertion and pulling of the medium cassette. ## Claims ### Claim at position 1 1-20. (canceled) ### Claim 21 A media cassette housing apparatus comprising: a guide portion configured to guide an insertion of a media cassette to a cassette housing area and to guide a pulling out of the media cassette from the cassette housing area; and a swingable member swingably provided to the guide portion, being swingable in inserting and pulling direction of the media cassette, wherein the swingable member is formed with a guide surface, the guide surface extending in insertion and pulling direction of the media cassette and configured to come into sliding contact with a part of the media cassette along the insertion and pulling direction of the media cassette, and the guide surface is formed with a flat surface that extends substantially parallel to the insertion and pulling direction of the media cassette. ### Claim 22 (depends on 21) The media cassette housing apparatus according to claim 21, wherein a swing fulcrum for the swingable member is provided to the swingable member. ### Claim 23 (depends on 22) The media cassette housing apparatus according to claim 22, wherein the swing fulcrum of the swingable member comprises a protrusion projected from a surface of the swingable member opposite from the guide surface. ### Claim 24 (depends on 23) The media cassette housing apparatus according to claim 23, wherein a center of gravity of the swingable member is located upstream of the swing fulcrum in the inserting direction of the media cassette. ### Claim 25 (depends on 21) The media cassette housing apparatus according to claim 21, wherein a swing fulcrum for the swingable member is provided to the guide portion. ### Claim 26 (depends on 21) The media cassette housing apparatus according to claim 21, wherein the swingable member is formed with a curvature portion at an upstream end portion of the guide surface in the insertion direction of the media cassette. ### Claim 27 (depends on 21) The media cassette housing apparatus according to claim 21, wherein the swingable member is provided to the guide portion such that the swingable member is slidable with respect to the guide portion in the insertion direction of the media cassette. ### Claim 28 (depends on 21) The media cassette housing apparatus according to claim 21, wherein the guide portion comprises: a recess in which the swingable member is accommodated; and an inclined surface formed upstream of the recess in the insertion direction of the media cassette. ### Claim 29 (depends on 21) The media cassette housing apparatus according to claim 21, wherein the guide portion is formed with a recess in which the swingable member is accommodated, and the swingable member is formed with a regulation portion configured to prevent the swingable member from coming off the recess. ### Claim 30 (depends on 21) The media cassette housing apparatus according to claim 21, wherein the regulation portion extends in a direction substantially orthogonal to the insertion and pulling direction of the media cassette. ### Claim 31 (depends on 21) The media cassette housing apparatus according to claim 21, wherein the guide portion includes a support portion configured to swingably support the swingable member, the support portion of the guide portion is formed with a first surface and a second surface both of which are configured to come in contact with the swingable member, the second surface is provided upstream of the first surface in the insertion direction of the media cassette, and the first surface is provided substantially parallel to the insertion direction of the media cassette, and the second surface is inclined with respect to the insertion direction of the media cassette. ### Claim 32 A media cassette housing apparatus comprising: a medium cassette configured to be inserted to and pulled out from a cassette housing area; a guide portion configured to guide an insertion of the media cassette to the cassette housing area and to guide a pulling out of the media cassette from the cassette housing area; and a swingable member swingably provided to the guide portion, being swingable in inserting and pulling direction of the media cassette, wherein the swingable member is formed with a guide surface, the guide surface extending in insertion and pulling direction of the media cassette and configured to come into sliding contact with a part of the media cassette along the insertion and pulling direction of the media cassette, and the medium cassette is formed, at an insertion leading end of the media cassette, with an inclined portion with respect to the insertion direction of the media cassette, wherein the inclined portion of the media cassette is provided at an area where the inclined surface comes into contact with the swingable member upon insertion of the media cassette. ### Claim 33 (depends on 32) The media cassette housing apparatus according to claim 32, wherein the guide portion comprises: a recess in which the swingable member is accommodated; and an inclined surface formed upstream of the recess in the insertion direction of the media cassette. ### Claim 34 (depends on 33) The media cassette housing apparatus according to claim 33, wherein the swingable member is formed with a curvature portion at upstream end portion of the guide surface in the insertion direction of the media cassette. ### Claim 35 (depends on 32) The media cassette housing apparatus according to claim 32, wherein the swing fulcrum of the swingable member comprises a protrusion projected from a surface of the swingable member opposite from the guide surface. ### Claim 36 (depends on 32) The media cassette housing apparatus according to claim 32, wherein the swingable member is provided to the guide portion such that the swingable member is slidable with respect to the guide portion in the insertion direction of the media cassette.
