Abstract:
The present invention relates to an image scanning apparatus having a scanning module, a transmission belt, a speed-change gear module, and a driving device. The driving device drives the transmission belt by using the speed-change gear module so as to drive the scanning module positioned on the transmission belt to scan an image. The speed-change gear module provides various speed-change ratios so that the driving device may drive the transmission belt at different speeds under the same speed of the driving device. In the embodiment, the speed-change gear module has a switching platform for accommodating the speed-change gear module. The stepping motor serving as the driving device is connected with the speed-change gear module by the motor gear. The transmission belt is connected with the speed-change gear module by the belt wheel. When moving or rotating the switching platform to switch between the deceleration ratios, a first set of deceleration gear and a second set of deceleration gear selectively engages with a motor gear.
Abstract:
A device for enhancing and shielding the light emitted from a rod-shaped light source. The device includes a plate strip made of light-reflecting material or provided with light-reflecting means disposed between the rod-shaped light source and a holder for holding the rod-shaped light source along the longitudinal axis direction thereof. The plate strip has an inwardly curved edge extending from the two ends thereof to the center. The width of the plate strip is gradually tapered from the two ends to the center.
Abstract:
A data storage device includes a storage module, a casing, a sliding member, and an elastic member. The storage module has a plurality of pins and memory units electrically interconnected. The casing includes a base, three sidewall members, a support member, a first abutting portion, and an accommodating region defined cooperatively by the sidewall members. At least one guide block is disposed on each of the oppositely arranged sidewall members. The first abutting portion is formed on one side of the support member. The sliding member has a second abutting portion and at least one guide rail corresponding to its respective guide block. The support member is arranged between the sliding member and the base. The elastic member is held by the first and second abutting portions on opposite ends thereof The compression and restoration of the elastic member allows the sliding member to selectively conceal the pins.
Abstract:
A hinge structure, an electronic device, and a cover utilizing the same. The hinge structure for supporting a cover comprises an elastic member, a connecting portion, and a pivot. The elastic member comprises two ends. The connecting portion is disposed on an end of the elastic member. The pivot is disposed on the other end of the elastic member and rotatably connected to the cover. A gap is formed between the pivot and the connecting portion. When the cover rotates from a first position to a second position, the cover applies a force on the pivot such that the width of the gap is changed via elasticity of the elastic member.
Abstract:
A scanner includes a platen, a scanning device and a supporting structure. The scanning device is movably disposed under the platen. The supporting structure is disposed in the scanning device comprising a contacting member and a resilient member connected to the contacting member. When the platen abuts the contacting member, the resilient member deforms to move the scanning device contacting the contacting member, such that a predetermined distance is maintained between the platen and the scanning device.
Abstract:
A film scanner includes a cold cathode lamp for producing visible light to scan a film containing a plurality of photographic images, an infrared source for producing infrared light to scan the film, and a detector or light sensor for sensing the visible light. The infrared light transmits the film to produce corresponding image signals. The cold cathode lamp is disposed between the infrared source and the film and the cold cathode lamp is in contact with the infrared source. In this way, before arriving at the film the infrared light is substantially uniformized by passing through the cold cathode lamp.
