An electronic apparatus that is capable of reducing occurrence of malfunction when an accessory is attached without enlarging an accessory shoe device. The electronic apparatus includes an accessory shoe device and a controller. The accessory shoe device is electrically connectable with an accessory and has terminals that are arranged in a line in a first direction that intersects perpendicularly with an attaching direction of the accessory. The controller is electrically connected to the terminals. At least one of the terminals differs from the other terminals in a length of an externally exposed part in a second direction that intersects perpendicularly with both the attaching direction and the first direction.

A connecting device of an accessory by which improvement in mechanical strength is compatible with arrangements of many connection terminals. The connecting device is detachably attachable to an accessory shoe device of an electronic apparatus. An engagement member is attachable to the accessory shoe device by sliding in a first direction. A holding member is fixed to the engagement member by fastening members. A connecting plug has connection terminals and is arranged at a front part in the first direction of the holding member. The fastening members are arranged at positions that are spaced apart from each other in a second direction that perpendicularly intersects with the first direction. A width of the holding member is shorter than a width of the engagement member in the second direction, and the connection terminals are arranged in an area between the positions of the fastening members.

A multi-function portable lighting apparatus is provided, including a lighting device, a carrier unit and a support unit. The carrier unit has two ends, with one end disposed with lighting device and the other coupled with support unit. The support unit includes a battery set, supplying power to lighting device. The carrier unit includes a clamping assembly, and the clamping assembly has a clamping opening, with direction perpendicular to light projection axis of lighting device. The clamping assembly includes a clamping base, a clamping element and a rotation element. The rotation element matches the clamping element in a means of screw. When the rotation element rotates, the clamping element moves in clamping base linearly to open or close clamping opening. The apparatus can be used as a flashlight or clamping onto a smart phone to provide lighting when the ambient light is insufficient for photography.

An accessory shoe device enabling multi-polarization of a connector for connection to an accessory without degrading the versatility thereof. The accessory is attached to an engagement member. A signal terminal connector has contacts arranged in a lateral direction orthogonal to an attaching direction. A pair of first engagement portions in the engagement member are spaced by a first width in the lateral direction, and a pair of second engagement portions in the engagement member are spaced by a second width larger than the first width. The signal terminal connector is disposed forward of the first engagement portions in the attaching direction. A length of the signal terminal connector in the lateral direction is larger than the first width and smaller than the second width. The second engagement portions are formed rearward of the first engagement portions in the attaching direction.

The present invention relates to a light emitting accessory for a portable terminal and an accessory light emitting system for a portable terminal, and to a light emitting accessory for a portable terminal, which is detachably coupled to the portable terminal to emit light using light of a flash of the portable terminal based on an external signal, a location of the portable terminal, and the like, and an accessory light emitting system for a portable terminal. A light emitting accessory for a portable terminal according to the present invention includes: a fixing unit that is detachably coupled to a portable terminal to cover a flash that is formed on a rear surface of the portable terminal; and a light emitting unit that receives light of the flash from the fixing unit to emit light.

A photography lighting device that provides a lighting source to a mobile electronic device. The mobile electronic device includes a front facing camera and a rearward facing camera. The lighting device includes a first light source movable from a first position to a second position. The first light source is rearward facing in the first position to provide illumination for the rearward facing camera. The first light source is forward facing in the second position to provide illumination for the forward facing camera. The lighting device further includes a second light source movable from a first position to a second position. The second light source is rearward facing in the first position to provide illumination for the rearward facing camera. The second light source is forward facing in the second position to provide illumination for the forward facing camera.

A system and method for synchronizing a remote lighting device to a camera using a hot shoe connection and an external device connected via the hot shoe connector. The external device receives TTL data and a synchronization signal from the camera via the hot shoe connector. The external device wirelessly communicates using a radio frequency transmitter a synchronization signal from the external device to a remote lighting device. The external device also wirelessly communicates a TTL information to the remote lighting device for use in synchronizing the remote lighting device to image acquisition by the camera.

A lamp for use with a computer, including cell phones and pads, comprises a body having a slot formed along its length for engaging the computer, by slipping over the edge of the computer's screen. The lamp includes a translucent cylinder, rotatably supported on the lamp body and supporting a parallel string of LEDs. A portion of the cylinder has an opaque cover so that the direction and intensity of the light cast by the lamp may be adjusted by rotating the cylinder.

An optical device includes a clamp seat and a light tuning assembly. The clamp seat includes a base, a curved potion extending from the base, and a pressing portion extending from the curved portion. The light tuning assembly includes a support frame disposed at the base, an optical lens restrained by the support frame, and an adjusting member coordinating with the optical lens. In an application of the optical device, a user may clamp a multimedia mobile communication device by the base and the pressing portion to allow the optical lens to align with a light projecting assembly of the multimedia mobile communication device. The adjusting member is rotated to adjust a distance between the optical lens and the light projecting assembly. Light from the light projecting assembly is then focused or dispersed through the optical lens to solve an issue of unadjustable light of a conventional solution.

An accessory shoe apparatus on an electronic apparatus includes an engagement member and a communication. A shoe apparatus on an accessory apparatus is detachably attachable to the accessory shoe apparatus. The engagement member engages with the shoe apparatus and including an opening portion that faces the engaged shoe apparatus. The communication element performs wireless communication with the shoe apparatus via an inside of the opening portion.
