Abstract: An exemplary embodiment provides a switch mechanism of which key top portion can be tilted with a simple mechanism. The switch mechanism includes a housing portion, a key top portion arranged such that a partial surface thereof is exposed at a peripheral portion of the housing portion, and a switch portion which is arranged in the inside of the housing portion and can be pressed in response to pressing of the partial surface of the key top portion. The housing portion includes a side support portion which tilts the key top portion by supporting the key top portion from a side when the partial surface of the key top portion is pressed.

Abstract: An example of peripheral device adds a predetermined function to a mobile device having an infrared communication function. The peripheral device includes an additional function unit, an infrared communication unit, and a support unit. The additional function unit has the predetermined function. The infrared communication unit is capable of performing infrared communication with the mobile device. The support unit detachably supports the mobile device so that a light emitting/receiving unit for infrared light of the mobile device is positioned so as to be capable of transmitting or receiving infrared light to or from the infrared communication unit.

Abstract: An imaging apparatus includes a flash light emitting portion moving between a housed position and a light emitting position, a biasing means for biasing the flash light emitting portion toward the light emitting position, a member to be locked moving with a movement of the flash light emitting portion, a locking means for locking the member to be locked in a state in which the flash light emitting portion exists at the housed position and suppressing change of the position of the flash light emitting portion, opposing a biasing force by the biasing means and a lock releasing means having an electromagnet and a moving portion, for releasing a locked state of the member to be locked by moving the moving portion in a direction apart from the electromagnet by applying electric current to the electromagnet and by allowing the locking means to pivot about an axis.
