Abstract
(EN)
[Problem] To secure a connection of a contact of a reference potential between an accessory and an electronic apparatus even when a static pressure or an impact is applied to the accessory. [Solution] This accessory (200) is detachably attached to an electronic apparatus (100), and a plurality of contacts (TA01-TA21) electrically connected to the accessory are arranged in a row. The plurality of contacts includes contacts (TA02, TA03, TA05-TA017, TA19, TA20) used to supply power from the electronic apparatus to the accessory or used for communication between the electronic apparatus and the accessory, first ground contacts (TA01, TA21) which are the contacts at both ends of the plurality of contacts and are connected to the ground, and second ground contacts (TA04, TA18) which when the accessory is connected to a selection of the plurality of contacts excluding the first ground contacts, are contacts at both ends of the selected plurality of contacts and are connected to the ground.

Le problème décrit par la présente invention est de sécuriser une connexion d'un contact d'un potentiel de référence entre un accessoire et un appareil électronique même lorsqu'une pression statique ou un impact est appliqué à l'accessoire. La solution selon l'invention porte sur un accessoire (200) qui est fixé de façon détachable à un appareil électronique (100), et sur une pluralité de contacts (TA01-TA21) connectés électriquement à l'accessoire qui sont agencés en une rangée. La pluralité de contacts comprend des contacts (TA02, TA03, TA05-TA017, TA19, TA20) utilisés pour fournir de l'énergie de l'appareil électronique à l'accessoire ou utilisés pour une communication entre l'appareil électronique et l'accessoire, des premiers contacts de mise à la terre (TA01, TA21) qui sont les contacts aux deux extrémités de la pluralité de contacts et qui sont reliés au sol, et des seconds contacts de mise à la terre (TA04, TA18) qui, lorsque l'accessoire est connecté à une sélection de la pluralité de contacts à l'exclusion des premiers contacts de mise à la terre, sont en contact aux deux extrémités de la pluralité sélectionnée de contacts et sont reliés au sol.
