- first and second gear shafts 61A and 61B are provided with a connecting portion 61c located on the radially outer side of the lower plate swing axis C1 and the upper plate swing axis C2 in the extending direction of the cord 7. Therefore, even when the upper plate 8 is swung with respect to the lower plate 9, it is possible to prevent the gear shafts 61A and 61B from interfering with the cord 7.
- the function of the rotation preventing means is borne only by the upper plate 8 and the lower plate 9, but instead of this, a synchro bar in which the function of the rotation preventing means is made independent of the upper plate 8 is used. You can also.
- the second embodiment will be described below.
- FIG. 12 shows a second embodiment of the present invention.
- the same reference numerals are given to the components corresponding to the components according to the first embodiment described with reference to FIGS. 1 to 11, and the description thereof is omitted.
- the cam bracket upper 1 and the gear bracket upper 3 are fixed to a resin upper case 11, and although not shown, the cam bracket The lower 2 and the gear bracket lower 4 are fixed to a resin lower case 12.
- the sync bar 13 is used for connecting the cam bracket upper 1 and the gear bracket upper 3, and for connecting the cam bracket lower 2 and the gear bracket lower 4. It is characterized by using a sync bar 14.
- the sync bars 13 and 14 are each formed of a plate-like member, and are configured such that both end portions are bent to have a U-shaped cross section from the viewpoint of increasing rigidity and improving attachment.
- the sync bars 13 and 14 are arranged so as to be erected with respect to the upper case 11.
- the sync bars 13 and 14 are both plate-like members, so that a space can be formed in the central portion between the cam unit 5 and the gear unit 6,
- the arrangement pace of a liquid crystal display device etc. can be taken widely.
- the sync bars 13 and 14 function as prevention means.
- the cam bracket upper 1 and the gear bracket upper 3 are fixed to the upper plate 8, and the cam bracket lower is fixed. 2 and the gear bracket lower 4 can be fixed to the lower plate 9, and the upper plate 8 and the lower plate 9 can also share the function as a prevention means.
- the cam unit 5 is arranged on the left side and the right gear unit 6 is arranged, but the cam unit 5 can be arranged on the right side and the gear unit 6 can be arranged on the left side.
- the left-right direction is the hinge for the electronic device S or the electronic device.
