Abstract:
1. An electronic apparatus, comprising: first and second casings, rotatably connected to each other through a bearing portion; and an opening/closing device, provided on the bearing portion, and automatically opening the first and second casings, wherein the opening/closing device includes a locking member which automatically opens the first and second casings until a predetermined obtuse opening angle and locks the first and second casings at the predetermined obtuse opening angle by operating an operating button; and wherein the first and second casings are allowed to be further opened until an opening angle greater than the predetermined opening angle by applying opening force to the first and second casings in a state that the first and second casings are opened at the predetermined obtuse opening angle, and further wherein the opening/closing device includes: a first cam member, which is mounted in the first casing so as to be nonrotatable; a second cam member, which is mounted in the second casing so as to be nonrotatable and slidable; a spring member, which comes into elastic contact with the first and second cam members and applies rotational force to the first and second cam members in a direction for opening the first and second casings to each other; a blocking member, which blocks the first and second casings from being opened by the action of the spring member; and a releasing member, which releases the preventing operation of the blocking member; and wherein the first and second cam members are provided with a fixing portion which temporarily holds an opened state of the first and second casings so as to block further opening of the first and second casings when the first and second casings are opened until the predetermined obtuse opening angle.
