Device for opening and closing of portable apparatus and portable apparatus using the device

Abstract

A device for opening and closing of a portable apparatus causes a fact that a first housing with an operation part at an upper surface and a second housing with a display part on an upper surface are superposed with each other, thereby rotatably opening and closing the second housing relatively to the first housing in a horizontal direction. The device for opening and closing comprises the following components: a star-shaped curve operation mechanism which sets the device for opening and closing between the first housing and the second housing; a point pressing stop facility which stops point pressing of the second housing to a certain rotation angle relatively to the first housing; and a rotation limiting facility which limits the rotation of the second housing relatively to the first housing to a certain rotation angle.

Description

technical field [0001] The present invention relates to an opening and closing device arranged between a first casing and a second casing constituting a portable electronic device and a portable electronic device using the opening and closing device. In further detail, it involves making the second casing and the second casing An opening and closing device of a portable electronic device in which the first casing is opened and closed through a star-shaped curve action, and a portable electronic device using the opening and closing device. Background technique [0002] In the past, as described in the following patent document 1, the opening and closing device and the portable electronic device using the opening and closing device have a first housing with an operation part such as a key on the upper surface and a second housing with a display part on the same upper surface. , from the fully overlapping state, the second housing is slid forward and backward relative to the fi...

AI Technical Summary

Problems solved by technology

[0004] The opening and closing devices described in the above-mentioned patent documents 1 and 2, no matter whether the second housing is slid relative to the first housing or opened and closed in the longitudinal direction, the second housing will be rotated; In addition, it is necessary to make the second housing have a rotating device. However, since both devices are necessary, there are problems such as complex structure and high manufacturing cost.
