Abstract: A projecting system is proposed. The projecting system comprises a mini projector with at least one first building block structure, a battery pack with at least one second building block structure, and an application unit with at least one third building block structure. One of the at least one first building block structure is electrically coupled to one of the at least one second building block structure. One of the at least one first building block structure is electrically coupled to one of the at least one third building block structure.

Abstract: The present invention provides a mini-projector apparatus for combining with a portable device. The mini-projector apparatus includes a base which is a heat sink. A mini-projector is disposed on the base. A heat conduction medium is disposed between the base and the mini-projector. A top housing is capable of combining with the base such that the mini-projector and the heat conduction medium can be fixed between the base and the top housing. The portable device may be fixed on the top housing.

Abstract: A projector having a reflection device includes a projector body and a reflection device. The projector body has a first surface and a second surface. A projection lens is disposed on the first surface. A reflection device is disposed beside the projection lens for reflecting a projected image of a mobile device connected to the projector body. Due to the reflection device, the projected image of the projector is reflected and projected, thereby allowing the path of image projection to change and go in another direction and enlarging the projected image with the reflecting mirror.

Abstract: A compound optical input device provides a pen-type optical mouse an additional function of joystick, which has a pen-type optical mouse and a upholding pedestal. The pen-type optical mouse has a barrel and a head. The head has an image-sensing device mounted therein. The upholding pedestal has a covering body and a sliding part. The covering body is formed with a through hole and a concavity for making the sliding part slide on a top portion of the covering body. The sliding part is formed with a receiving cavity for holding the head of the pen-type optical mouse. The head penetrates through the through hole and movably extends into the covering body.

Abstract: A non-contact type coordinate measurement device includes a housing, a stick, an optical transmitting member and an image-sensing member. The housing has a supporting portion formed at a top thereof, and is closed and made of opaque materials. The stick is orientated to the housing via the supporting portion, and has an operation portion exposed out of the housing and a detection portion received in the housing. The optical transmitting member is arranged inside the housing. The image-sensing member is disposed on the detection portion of the stick for generating an image variation while the stick is manipulated.

Abstract: The present invention relates to a USB structure with a protection device, especially applying to a USB connector structure without traditional cap but still with protection function. The present invention adopts simple mechanism, spring and positioning structure, pivotal structure and rotational structure, to approach protection object, therefore it saves a lot on cost and manufacturing processes.

Abstract: The present invention relates to a USB structure with protection means, especially applying to a USB connector structure without traditional cap but still with protection function. The present invention adopts simple mechanism, spring and positioning structure, pivotal structure and rotational structure, to approach protection object, therefore it saves a lot on cost and manufacturing processes.

Abstract: A hidden document-covering device for a scanner, especially for a scanner built in the case of a computer in which a device is used for holding the document on a moving tray during scanning process. The document-covering device always hides itself in the case even when the tray moves out. During the scanning process, the document for scanning is firmly pressed onto the tray to prevent from curling or sliding. After scanning, i.e. when the tray moving out, the document-covering device will release the document for easy loading and unloading.

Abstract: A built-in scanner for computers includes a transport portion and a case. The case is mounted in a computer, and the transport portion is extractive. There is only one way to feed document sheets, the document sheet is thus smoothly and fed through the built-in scanner without vibration. As the transport portion is engaged into the case, the built-in scanner is completely assembled. The transport portion of the built-in scanner can transport document sheets one by one for scanning. In addition, as the document sheet is jammed, the transport portion of the built-in scanner can be extracted for repairing.

Abstract: A sheet-feed type scanner including a scanner base defining a scanning plane and having a document feed hole at one end into which document to be scanned is inserted; an image pick-up mechanism fixedly mounted in the scanner base and comprised of a light source, a reflector, a focus lens and an image sensor, and adapted to pick up image of inserted document within the scanning plane and to convert detected image signal into corresponding electrical signal; a document sheathe adapted for holding document for scanning, the document sheathe having a first flat sheet member and a second flat sheet member connected together for holding document in there between in a flat manner for scanning; and a transmission mechanism controlled to move the document sheathe along the scanning plane, for permitting document to be scanned by the image pick-up mechanism; and a document guide adapted for guiding the document sheathe through the scanning plane.

Abstract: A window arrangement including a scanning area in a scanner through which document is moved and scanned; a window mounted in the scanning area through which scanning light passes onto document to be scanned; a locating device adapted to hold the window in the scanning area; and a pick-up device fastened to one end of the window through which the window can be pulled away from the locating device out of the scanning area for a maintenance work.

Abstract: An improved document tray for scanners includes a supporting part and covering means. The supporting part is used to hold a document for scanning and the covering means is used to press and fix the document. The covering members does not need to be opened for inserting a document into the supporting part. The document tray of the invention indeed improves the drawbacks of the prior art so that the tray will not jam or be damaged when it is pushed into the scanner.
