Embodiment Construction

[0033] Hereinafter, preferred embodiments of a printer to which the present invention is applied will be described with reference to the drawings.

[0034] figure 1 It is a perspective view showing the appearance of the printer according to this embodiment. The printer 1 according to this embodiment is, for example, a printer used as a receipt printer in a POS system.

[0035] In the printer 1 , components described later are provided inside a resin exterior case 4 composed of an upper case 2 and a lower case 3 . The upper surface of the upper case 2 is an inclined surface inclined so that the front side becomes lower, and a discharge port 6 for the recording paper 5 is formed on the front side of the upper surface. An opening and closing cover 7 is provided on the upper surface portion on the rear side relative to the discharge port 6 . The access cover 7 can be opened and closed centering on the rear end side, and can be opened by pressing an open button 8 (manual operatio...

Abstract

To propose a cover lock mechanism for a printer, by which a cover frame can be securely locked to a printer frame, even if the position of the cover frame in a closed condition moves up and down. The cover frame 13 of the printer 1 is mounted to the printer frame 12 so as to be openable and closable at its rear edge acting as the center. The cover frame 13 is locked to the printer frame 12 by a lock mechanism 40. The lock mechanism 40 has a lock lever 44 and a hook 42. The lock lever 44 is arranged on the left edge of a lock plate 41, which is mounted slidably from side to side on the front edge of the cover frame 13. The hook 42 is arranged on the printer frame 12. When the cover frame 13 is closed, after the lock lever 44 hits the hook 42, the lock lever 44 goes over the hook 42 while the lock plate 41 slides to the left side, and then the lock lever 44 slides to the right side. Thereby, a securing surface 51c of the lock lever 44 is secured to the lock lever securing surface 42c of the hook 42 from the bottom, and a locking state is formed. (C)2004,JPO&NCIPI.

Description

technical field [0001] The present invention relates to a printer for POS systems, cash registers and the like. More specifically, the present invention relates to a cover lock mechanism for locking the cover frame to the body frame of a printer in which a cover frame is openably and closably attached to the body frame of the printer. Background technique [0002] Thermal printers that print on roll paper are widely used in POS systems and the like. In this type of printer, a cover frame is openably and closably attached to the main body frame of the printer. When the cover frame is opened, the roll paper loading part is fully opened, and printers with a structure that can easily perform roll paper replacement operations are widely known. . In addition, a platen roller is attached to the front end of the cover frame, and when the cover frame is opened, the platen roller can be separated from the thermal head, and the structure that can easily perform the operation of setti...
