DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a relatively small electronic device such as a so-called electronic organizer, and more particularly to an electronic device having a main body and a lid provided to be capable of angular displacement with respect to the main body.

[0002]

2. Description of the Related Art FIG.
It is a side view which shows the schematic structure of the connection means 4 of a shaft structure.
The electronic device 1 includes a main body 2 including an operation unit and the like, a display unit 10
And the like, and a connecting means 4. The connecting means 4 includes a main rotating shaft portion 5, a connecting portion 6, and a sub rotating shaft portion 7. The main rotation shaft portion 5 is formed in a columnar shape, and pins 8 are provided at both ends on the outer side in the axial direction. The sub rotary shaft 7 is formed in a columnar shape with a smaller diameter than the main rotary shaft 5, and pins 9 are provided at both ends on the outer side in the axial direction.

The main rotating shaft 5 and the pin 8 are provided inside the main body 2, and the pin 8 is supported by the main body 2. Therefore, the main rotation shaft portion 5 uses the pin 8 as a rotation shaft to
Angular displacements are possible within. Between the outer peripheral surface of the main rotary shaft portion 5 and the outer peripheral surface of the sub rotary shaft portion 7, a flat connecting portion 6 is provided. Accordingly, the sub-rotating shaft portion 7 is
Following the angular displacement of

[0004] The sub-rotating shaft portion 7 and the pin 9 are provided inside the lid 3, and the pin 9 is supported by the lid 3. Therefore, the lid 3 can be angularly displaced with the pin 9 as a rotation axis.

The frictional force between the pin 8 of the main rotary shaft 5 and the main body 2 is designed to be smaller than the frictional force between the pin 9 of the sub rotary shaft 7 and the lid 3. Therefore, from a so-called closed state in which the main body 2 and the lid 3 are opposed to each other, when a force is applied to angularly displace the lid 3 in the direction of the arrow R1, the lid 3 and the sub-rotation shaft 7 are fixed. The main rotation shaft 5 rotates. Thereafter, the main rotary shaft 5 is moved to the maximum angular displacement position with the pin 8 as the rotation axis, for example, the position where the main body side end 3a of the lid 3 comes into contact with a mounting surface such as a desk on which the main body 2 is mounted. Upon reaching, the main rotating shaft 5 stops. When a further force is applied in this state, the lid 3 starts angular displacement with the pin 9 as a rotation axis.

When the main rotary shaft 5 reaches the maximum angular displacement position with the pin 8 as the rotation axis, as shown in FIG.
The main body side end portion 3a and the side surface portion 2a of the main body 2 overlap. In addition, since the electronic device 1 is used with the user positioned in the direction of the arrow R2, the side portion 2a is a rear portion with respect to the user.

[0007]

As described above, in the conventional electronic device 1 including the connecting means 4 having a biaxial structure, when the main rotary shaft portion 5 is angularly displaced to the maximum angular displacement position, the lid is closed. The main body side end 3 a of the main body 3 overlaps with the rear face 2 a of the main body 2.

In some cases, a connector or the like to which a terminal wire for connecting an external device such as a printer or a floppy disk drive is attached is provided on the rear portion 2a of the main body 2. In this case, in a state where the terminal wire is attached to the connector, the end 3a is in contact with the connector, the lid 3 including the display unit 10 is held at a position that is easy for the user to see, and an external device is used. And inconvenience has arisen.

Further, as shown in FIG. 7, with the conventional connecting means 4 having a biaxial structure, the lid 3 cannot be held at an upper position with respect to the main body 2. Therefore, the display unit 10 becomes far from the user, and the angle θ1 formed between the display surface of the display unit 10 and the line of sight indicated by the two-dot chain line A is small, which causes a problem that the display unit 10 becomes difficult for the user to see. .

An object of the present invention is to provide an electronic device capable of holding a cover including a display unit at a position that is easy for a user to see.

[0011]

According to the present invention, there is provided an electronic apparatus comprising: a main body including an operation section; a lid including a display section; and connecting means for connecting the lid to the main body so as to be angularly displaceable. The connecting means is pivotally supported on the main body side, angularly displaced in a first predetermined range, and provided with a locking groove on an outer peripheral surface thereof; A connecting member including a sub-rotating shaft portion that is angularly displaced in the range of 2, and a connecting portion that connects the main rotating shaft portion and the sub-rotating shaft portion;
A control member comprising: a locking spring for locking / releasing the main rotating shaft portion to / from a locking groove of the main rotating shaft portion at a predetermined angular displacement position within the first range; and a support member for the locking spring. Wherein the frictional force between the auxiliary rotary shaft and the lid is set to be larger than the frictional force between the main rotary shaft and the main body and smaller than the locking force of the control member. Equipment.

[0012]

According to the present invention, the connecting means for connecting the main body and the lid includes a connecting member and a control member. The connection member is pivotally supported on the main body side and has a predetermined first
A main rotating shaft portion which is angularly displaced in the range of and a locking groove is provided on an outer peripheral surface thereof; a sub-rotating shaft portion which is axially supported on the lid side and is angularly displaced in a second predetermined range; And a connecting portion for connecting the sub-rotating shaft portion with the portion. In the main rotating shaft portion, a locking spring is locked / released in a locking groove at a predetermined angular displacement position within the first range by the control member. Therefore, it is possible to reliably hold the lid at the predetermined angular displacement position with respect to the main body.

For example, the lid is angularly displaced with respect to the main body from a closed state where the main body and the lid face each other. At this time, since the frictional force between the sub-rotating shaft and the lid is set to be larger than the frictional force between the main rotating shaft and the main body, the lid is stopped with respect to the sub-rotating shaft, The main rotating shaft is angularly displaced with respect to the main body.

When the main rotary shaft reaches a predetermined angular displacement position, the main rotary shaft is locked in a locking groove on the outer peripheral surface by a locking spring of a control member, and the angular displacement stops. When a further force is applied to the lid in this state, the locking force of the control member is set to be greater than the frictional force between the sub-rotating shaft and the lid, so the main rotating shaft is stopped. The body is angularly displaced with respect to the auxiliary rotation shaft.

The lid stops angularly displaced by a predetermined second range. Therefore, the second predetermined position is set such that the lid in this state is located at a position that is easy for the user to see.
And the predetermined angular displacement position may be set. When a further force is applied to the lid in this state, the locking force of the control member with respect to the locking groove by the locking spring is released, and the main rotary shaft portion is angularly displaced with respect to the main body, so that the predetermined first range Stops when the maximum position is reached. When the lid is closed, the above operations are performed in the reverse order.
