Claim:
A printer apparatus, comprising: a printer body for printing on a paper sheet; a paper support attached to said printer body, and including a flat plate portion for supporting the paper sheet to be fed to said printer body; paired bearing portions provided at said printer body to face each other; and paired rotating shaft portions provided at said paper support, and rotatably journaled by said paired bearing portions, wherein each of said paired rotating shaft portions includes a shaft body protruding from a side opposite to a side where said paired rotating shaft portions face each other, a shaft support portion provided at said flat plate portion to support said shaft body, a tab portion provided at said shaft support portion, and a protruding portion formed at said shaft support portion on the side opposite to the side where said paired rotating shaft portions face each other, each of said paired bearing portions includes a bearing body for receiving and journaling said shaft body, an engaging portion formed at said bearing body on a side where said paired bearing portions face each other, and receiving said tab portion to restrict axial movement of said rotating shaft portions, and a recess formed at said bearing body on the side where said paired bearing portions face each other, and receiving said protruding portion, when said protruding portion is received in said recess, and said paper support is opened to stand with respect to said printer body so that the paper sheet can be fed, said tab portion disengages from said engaging portion, resulting in that said paper support is made detachable from and attachable to said printer body, and when said paper support is tilted toward said printer body to be closed, said tab portion engages said engaging portion, resulting in that axial movement of said paper support is restricted.
