Description
BACKGROUND OF THE
The slide device is a device that allows a pair of members to move relative to each other by a predetermined distance, and is widely used in electronic devices such as mobile phones and portable game machines in recent years.
In such an electronic apparatus such as a cellular phone or a portable game machine, a key input unit or the like provided with a plurality of keys is provided on any one member (first member) of the pair members, and a liquid crystal panel or the like is provided on the other member And the second member is moved on the first member by the sliding device to expose or cover the key input portion.
Further, in recent years, in order to increase the opening angle of the first member and the second member to 180 degrees or more, or to use the display more widely, it is preferable that the first member and the second member each have a rotation shaft, There has been developed a biaxial slide apparatus in which a member is opened in a state opposite to a horizontal or initial closed state, and this biaxial slide apparatus is gear-engaged to interlock the respective rotation shafts.
However, in the biaxial slide apparatus connected with the conventional gear, a noise or an impact is generated due to the rotating gear which is engaged when opening the gear, which has a disadvantage that the user feels a sense of operation. In addition, the conventional structure described above has a disadvantage in that it can not be provided in the biaxial slide device, and therefore, it needs to be provided separately in the first and second members provided with the biaxial slide device.
According to an embodiment of the present invention, there is provided a biaxial slide device capable of improving a user's operation feeling and easily adjusting an opening angle during a sliding operation, and an electronic apparatus having the same.
According to an aspect of the present invention, there is provided an electronic apparatus comprising a housing, a first rotating shaft and a second rotating shaft rotatably arranged in parallel with each other in the housing, a cam unit provided on the first rotating shaft and the second rotating shaft, A pair of link holes through which the first rotation axis and the second rotation axis respectively pass and a guide projection slidably engaged with the respective helical grooves of the first and second rotation shafts on the inner circumferential surfaces of the link holes A biaxial slide apparatus may be provided in which one of the first and second rotation shafts rotates together with the guide projection of the link bar moving along the spiral groove when one of the first and second rotation shafts rotates.
The first rotation axis and the second rotation axis may include a cylindrical rotation axis portion and a locking axis portion in which the cam unit is provided, and the helical groove may be provided in the rotation axis portion.
The cam unit further includes a fixed cam having a pair of fixed cam holes through which the first rotation shaft and the second rotation shaft respectively pass and cam protrusions for cam engagement, A rotation cam having a cam groove for cam engagement and an elastic member for resiliently urging the fixed cam toward the rotation cam.
The first rotation axis and the second rotation axis include a cylindrical rotation axis portion and a locking axis portion provided with the cam unit. The locking axis portion is provided to have a plate surface, and the fixed cam is rotated relative to the locking axis portion And the rotation cam may be provided to rotate together with the engagement shaft portion by the plate surface.
In addition, each of the helical grooves provided in the first and second rotation shafts may be provided opposite to the circumference of the rotation shaft at intervals of 180 degrees.
The helical grooves provided on the first rotation axis and the second rotation axis may be provided so that the first and second rotation axes rotate in opposite directions when the link bar is moved.
According to another aspect of the present invention, there is provided an image forming apparatus comprising: a first member and a second member which are overlapped, wherein the first member and the second member are rotatably opened, The first and second rotary shafts of the biaxial slide apparatus may be provided with the electronic devices respectively installed in the first and second members.
The biaxial slide apparatus and the electronic apparatus having the same according to the present invention can improve the operational feeling of the user due to no noise or shock generated when the conventional gear is engaged because the first rotary shaft and the second rotary shaft are linked by the link.
Further, the biaxial slide apparatus and the electronic apparatus having the same according to the present invention can easily set the opening degree of the first and second rotating shafts by changing the pitch of the helical grooves of the first and second rotating shafts on which the link is provided, When the distance between the two rotary shafts is set appropriately, the two-axis slide device can be easily designed and applied to various electronic apparatuses of different sizes.
