Abstract:
A printing system includes a portable communication device, a printing device and plural transmission channels. The printing device is used for receiving a to-be-printed data from the portable communication device, thereby performing a printing task. The plural transmission channels are selectively in communication with the portable communication device and the printing device for transferring the to-be-printed data to the printing device. The portable communication device includes a controlling unit for judging and setting priority values of the transmission channels and selecting one of the transmission channels as a priority transmission channel according to the priority values of the transmission channels, so that the to-be-printed data is transmitted from the portable communication device to the printing device through the priority transmission channel.
Abstract:
A hinge device is used in an office machine including a main body and an upper cover. The hinge device includes a base, a rotating shaft and an elastic structure. The base includes a connecting part and a shaft sleeve part. The connecting part is fixed on the main body. The shaft sleeve part has a channel and a baffle. The baffle is arranged at an external surface of the shaft sleeve part. The rotating shaft is penetrated through the channel. The elastic structure includes a fixing part and a bending part. The bending part is correspondingly moved on the external surface of the shaft sleeve part during a process of opening or closing the upper cover. When the bending part is sustained against the baffle, the upper cover is positioned in an open status to define an included angle between the upper cover and the main body.
Abstract:
A calibrating and positioning structure of a scanning apparatus is provided. The scanning apparatus includes a scanning platform and a scanning window. The scanning window has a wide edge. The calibrating and positioning structure includes a calibrating part and at least one positioning part. The calibrating part is disposed on the scanning platform, and aligned with the wide edge of the scanning window. The at least one positioning part is partially overlapped with the calibrating part, wherein the positioning part is not aligned with the wide edge of the scanning window.
Abstract:
A multifunction peripheral includes a scanning platform, a scanning module, a recording unit and a controlling unit. The scanning platform includes a standby position, a position-calibrating structure and a datum line. The scanning platform is divided into a first zone and a second zone by the datum line. The position-calibrating structure is included in the second zone. The scanning module is movable with respect to the scanning platform for performing a scanning operation. The recording unit is used for recording a parameter associated with a position of the scanning module with respect to the scanning platform. The controlling unit is used for controlling movement of the scanning module according to the parameter recorded in the recording unit, so that the scanning module is moved through the position-calibrating structure to perform a position-calibrating operation. After the position-calibrating operation is completed, the scanning module is moved to the standby position.

Abstract:
A light projecting apparatus of a scanner module and a method for arranging the light sources thereof are provided. The light projecting module includes a substrate with a first end, a second end and a middle section. The first end and the second end are respectively positioned at both sides of the middle section. The light projecting module also includes multiple light emitting diodes (LEDs) positioned on the substrate. An arrangement spacing interval is formed between every two adjacent light emitting diodes; the arrangement spacing intervals are respectively decreased gradually from the middle section toward both the first end and the second end.
Abstract:
A sheet stopping mechanism includes a guiding element, a sheet stopping element and a guiding slot. The guiding element includes a sheathing part and an extension arm. The sheathing part is sheathed around an axle of the sheet pick-up roller. The sheet stopping element includes a stopping part, a protrusion part and a contact part. The extension arm of the guiding element is upwardly sustained against at the contact part of the sheet stopping element. The protrusion part of the sheet stopping element is accommodated within the guiding slot. When the sheet pick-up roller is moved toward a sheet input tray, the guiding element is uplifted. As a result, the protrusion part of the sheet stopping element is shifted and rotated in the guiding slot, and a front edge of the paper sheet is no longer hindered by the stopping part of the sheet stopping element.
Abstract:
A paper output mechanism for an automatic document feeder, including: a seat; a connecting shaft, passed through the seat; and a paper feeding roller, placed around the connecting shaft, and including: a shaft portion; a roller portion, placed around the shaft portion; and adapted to convey a document, and an elastic element, placed around the shaft portion, and one end thereof being connected to the seat.
Abstract:
The present invention relates to a belt tension adjustment mechanism for use with a device including a main body and a belt pulley set. The belt pulley set includes a belt. The belt tension adjustment mechanism includes a slab, at least two tension pulleys and a fixing element. A tight tension force and a slack tension force are exerted on the opposite sides of the belt to define a tight side and a slack side of the belt when the belt pulley set runs. A counterforce is generated from the tight side of the belt to exert on the tension pulley contacting with the tight side, the slab is moved in response to the counterforce. The slack side of the belt is suppressed by the tension pulley contacting with the slack side such that the slack tension force is adjustable.
Abstract:
An image reading apparatus for use in an office machine includes a first image sensor and a second image sensor. The first image sensor is disposed in an automatic document feeder of the office machine for sensing and reading a first side of a document. The first image sensor includes a first optical module, a first correction element and an elastic sustaining element. The first optical module includes a first light source, a first light-sensing element and a glass surface. The first correction element is arranged at an opposite side of the first optical module. The elastic sustaining element has a free end sustained against the glass surface of the first optical module, thereby facilitating a close contact between the document and the glass surface. The second image sensor is disposed in an office machine main body for sensing and reading a second side of the document.
