SELECTIVE PRINTING MECHANISMS, i.e. MECHANISMS PRINTING OTHERWISE THAN FROM A FORME; CORRECTION OF TYPOGRAPHICAL ERRORS ## Abstract A printer case assembly structure includes a print main body; a first case installed at a portion of the printer main body; a second case installed to surround the print main body except for an installing area of the first case and a cover installation opening part area; a latching sill part formed in the print main body and the first case to assemble the first case; a separation prevention part formed in the first and second cases to prevent the first case from being separated from the latching sill part; and an assembly hook unit formed in a hook structure in the printer main body and the second case to assemble the second case. ## Claims ### Claim 1 A printer case assembly structure comprising: a printer main body; a front case configured to be detachably attached at a front portion of the printer main body; a main case configured to surround the printer main body except for a front installation area for the front case and an upper installation area for a cover; a latching sill formed in the printer main body and in the front case to assemble the front case with the printer main body; and a hook assembly formed in the printer main body and in the main case to assemble the main case with the printer main body, wherein the main case includes a main body receiving plate extending parallel to a bottom plate of the main case, and the main body receiving plate has a plate-shaped body, and wherein a main body support protrusion part placed on a bottom portion of the printer main body is formed at a free end of the plate-shaped body. ### Claim 2 (depends on 1) The printer case assembly structure of claim 1, wherein the hook assembly includes: a support hook member including an elastic support protruding from the printer main body and a support hook formed on the elastic support; and a support hook latch formed in the main case for facing the support hook member to be latched with the support hook member. ### Claim 3 (depends on 2) The printer case assembly structure of claim 2, wherein the support hook member further includes a disassembly handle. ### Claim 4 (depends on 2) The printer case assembly structure of claim 2, wherein the main case further includes: the bottom plate having an opening; and side plates placed on both lateral sides of the bottom plate, a rear plate placed on a rear portion of the bottom plate. ### Claim 5 (depends on 4) The printer case assembly structure of claim 4, wherein the support hook latch is formed at one side of the plate-shaped body of the main body receiving plate. ### Claim 6 (depends on 1) The printer case assembly structure of claim 1, wherein the hook assembly includes: a support hook member including an elastic support protruding from the main case and a support hook formed on the elastic support; and a support hook latch formed in the printer main body for facing the support hook member to be latched with the support hook member. ### Claim 7 (depends on 6) The printer case assembly structure of claim 6, wherein the support hook member further includes a disassembly handle. ### Claim 8 (depends on 1) The printer case assembly structure of claim 1, further comprising a separation prevention assembly formed in the front and main cases to prevent the front case from being separated from the latching sill, wherein the separation prevention assembly includes: a separation prevention groove formed in the front case; and a protrusion formed at an end of the main case for facing the separation prevention groove to be inserted into the separation prevention groove. ### Claim 9 (depends on 1) The printer case assembly structure of claim 1, further comprising a shaking prevention protrusion formed on a contact portion between the printer main body and the front case to prevent the front case coupled to the printer main body from shaking. ### Claim 10 (depends on 1) The printer case assembly structure of claim 1, further comprising an opening/closing cover connected to the printer main body, the opening/closing cover being opened and closed for paper replacement, wherein the opening/closing cover includes a hinge member including a hinge shaft having a latching hook in an arc-shaped hinge guide, and wherein the printer main body includes a shaft support member having a hinge hole into which the hinge shaft is to be inserted. ### Claim 11 A printer case assembly structure comprising: a printer main body; a front case configured to be detachably attached at a front portion of the printer main body; a main case configured to surround the printer main body except for a front installation area for the front case and an upper installation area for a cover; and a hook assembly formed in the printer main body and in the main case to assemble the main case with the printer main body, wherein the hook assembly includes: a support hook member including an elastic support protruding from the printer main body and a support hook formed on the elastic support; and a support hook latch formed in the main case for facing the support hook member to be latched with the support hook member, wherein the support hook latch includes: a hook receiving protrusion forming an insertion hole into which the support hook is to be inserted; a reinforcing protrusion extending from the hook receiving protrusion; and a guide wedge formed on an upper portion of the reinforcing protrusion to guide the support hook member. ### Claim 12 A printer case assembly structure comprising: a printer main body; a front case configured to be detachably attached at a front portion of the printer main body; a main case configured to surround the printer main body except for a front installation area for the front case and an upper installation area for a cover; a latching sill formed in the printer main body and in the front case to assemble the front case with the printer main body; and a hook assembly formed in the printer main body and in the main case to assemble the main case with the printer main body, wherein the latching sill includes: a sliding protrusion formed at both lateral sides of the first case; and a sliding protrusion moving groove including a horizontal moving groove formed in the printer main body facing the sliding protrusion, and a vertical moving groove communicating with the horizontal moving groove.
