Additionally, an alternative easy-load mechanism and its associated method for installing a printer cartridge comprises a moveable cartridge bay for holding the printer cartridge, a lever device for accepting an external force, a first engagement device, a second engagement device, and a third engagement device for transferring force from the lever device to the moveable cartridge bay, wherein the lever device is able to move the movable cartridge from an initial position to a target position via the engagement devices.

Abstract: A screw cap for covering a head of a screw in a screw hole (20) of a housing (2) of a portable electronic device. The screw hole includes a wide upper portion (202) and a narrow lower portion (204). The screw cap includes a main body (12) and an elastic ring (14). The main body includes a wide head (122) and an adjoining narrow cylindrical body (124). An upper first groove (1242) and a lower second groove (1243) are defined in the cylindrical body. The first groove is deeper than the second groove. When the elastic ring is engaged in the second groove, the screw cap can be interferentially engaged in the screw hole. When the screw cap is pushed so that the elastic ring is engaged in the first groove, the screw cap can be easily removed from the screw hole.

Abstract: A photo printer includes a housing, a circuit board having a first set of female conducting terminals and a control circuit for controlling the operation of the printer, a connection module having a connector that contains both a first set of male conducting terminals for engaging with the first set of female conducting terminals and a second set of female conducting terminals, and an external card for storing data having a second set of female conducting terminals for engaging with the first set of female conducting terminals.

Abstract: A screw cover (100) includes a cap (10) made of stretchable material, and a post (20) covered by the cap. The cap includes an end (12) having a round opening (122). A diameter of the end is slightly less than or the same as a diameter of a screw hole (32). The post includes a top column (22). A diameter of the top column is slightly greater than a diameter of the opening, so that the post is engaged in the opening. The diameter of the end is thus expanded to be slightly greater than the diameter of the screw hole, so that the screw cover can be secured in the screw hole. In disassembly, the top column is pushed so that the post moves down, and the diameter of the end returns to its original size. The screw cover can then be easily dropped out from the screw hole.

Abstract: A hinge (300) includes a cam (32), a cam follower (30), a torsional spring (31), and a can (33). The cam includes a round flange (321), with a notch (321b) defined therein. The cam follower connects with the cam, and includes an engaging ring (301) around an open end thereof and a projection (303) on an inner wall thereof. The projection is removably engaged in the notch of the cam. The spring is twisted and attached in the cam follower, with one end fixed on the cam follower and the other end fixed on the cam. The can defines a groove (334) rotatably receiving the engaging ring of the cam follower, and a guiding hole (335) movably receiving the cam. The hinge has a relatively simple and stable unified structure.

Abstract: A replaceable panel device (1) includes a panel (20) with a mounting portion (24), a locking subassembly (30), and a top cover (40) with a block (45). The mounting portion has at least one slideway (241), a recess (242), and two locating grooves (243). The locking subassembly is accommodated in the mounting portion of the panel. The locking subassembly has a button (31), an elastic rod (32), and a slider (33). The button has at least one rail (312), a hole (313) defined at top of the rail. The slider has at least one slot (331) and a rabbet (332). The slider is received in the recess. The rail is received through the slideway and the slot. The elastic rod is received through the hole. Ends of the elastic rod are located in the locating grooves. The rabbet engagingly receives the block of the top cover.

Abstract: The present invention relates to an image scanning apparatus and more particularly to a dual transmissive/reflective image scanning apparatus with protective apparatus. The present invention includes a housing, an original cover, a tray of a first type, and a tray of a second type. The housing provides a slot, within which the tray of the first type or the tray of the second type may be selectively inserted. The tray of the first type is inserted within the slot for reflective scanning, while on the other hand, the tray of the second type is selectively inserted within the slot for transmissive scanning. In addition, a first device is provided within the housing, and the tray of the first type has a second device for selectively coupling with the first device. The original cover has a third device for selectively coupling with the first device.

Abstract: A vehicle wide-angle rearview mirror frame has a storage box pivotally connected at a lower front edge to a lower rear edge of the rearview mirror frame, so that the storage box could be opened or closed by turning the rearview mirror frame away from or toward a front opening of the storage box. The storage box is then clamped onto a mounting plate of the rearview mirror frame of the vehicle. Miscellaneous items may be conveniently positioned in the storage box behind the wide-angle rearview mirror frame for easy access of these items without affecting the original function of the rearview mirror.

Abstract: The present invention provides a dual transmissive/reflective image scanning apparatus for improving the scanning quality of reflective originals. The present invention includes a slot for selectively accommodating a tray of a first type or a tray of a second type. For reflective scanning, the tray of the first type, which includes a means of transparent material such as glass, is inserted within the slot. For transmissive scanning, the tray of the second type without a means of transparent material may be selectively inserted within the slot. As scanning transparent originals, a light source from the original cover passes directly thought the transparent originals and thus it reduces obstruction that may be caused by a transparent material. Furthermore, either the tray of the first type or the tray of the second type is allowed to be withdrawn from the housing for cleaning greasy dirt or dust deposited on the glass or installing various holders for transparent originals.

Abstract: Disclosed is an automatic chalk ash cleaner including an elongated casing horizontally fastened to a blackboard at the bottom and covered with a wire netting cover, a brush assembly driven by a power drive through a transmission mechanism to sweep chalk ash away from the erasers placed on the wire netting cover and to sweep out fallen chalk ash.
