The tilt holder provided on the tilt shaft can rotate the camera holder about the camera holder rotation axis as a pivot through the camera holder tilt bar fitted slidably.
[0009]
In the tilt structure of the camera-equipped entrance hall according to the present invention, the tilt shaft is provided with a tilt adjustment concave portion on the outer peripheral portion of the tilt shaft bending portion, and the case is provided with a tilt adjustment convex portion engaged with the tilt adjustment concave portion. When the tilt shaft rotates, the tilt shaft deflecting portion bends and meshes with the next tilt adjusting recess, thereby enabling the tilt adjustment in a stepwise manner. By having these, when the tilt knob is slid in either the upper or lower direction and the tilt shaft is rotated about the tilt shaft rotation axis, the tilt adjustment convex portion deflects the tilt shaft flexure portion, A continuous operation of meshing with the tilt adjustment recess can be performed.
[0010]
Further, in the tilt structure of the entrance unit with a camera according to the present invention, the rotation radius of the tilt shaft rotating rod that is directly tilted by the tilt knob is made larger than the rotation radius of the tilt rod holder of the tilt shaft holding the camera holder. Thus, the tilt operation can be easily performed with a small force and the camera holder can be held. Further, the rotation radius of the tilt shaft rotary rod is increased by a factor of 2 to 3 compared to the rotation radius of the tilt rod receiver of the tilt shaft. By forming in this way, when the tilt knob is slid in either the upper or lower direction and the tilt shaft is rotated about the tilt shaft rotation axis, the tilt shaft is compared with the rotation radius of the tilt rod holder of the tilt shaft. Since the rotation radius of the rotary rod is larger, the tilt operation can be easily performed with a small force, and the camera holder can be held with a small force. It has been confirmed by the present inventor that when the tilt operation is performed with a small force, the rotation radius of the tilt shaft rotary rod is 2 to 3 times the rotation radius of the tilt rod receiver.
[0011]
[Form of the present invention]
Hereinafter, preferred embodiments of the tilt structure of the camera-equipped entrance machine according to the present invention will be described in detail with reference to the drawings.
[0012]
As shown in FIGS. 2A and 2B, the tilt structure of the entrance apparatus with a camera of the present invention pivots the camera holder 4 holding the camera 9 to the case 2 so that it can be tilted. In order to protect the camera 9 that can be tilted in the case 2, the camera holder 4 is swung by the tilt knob 3 that is slid up and down and can be tilted on the front side surface 2 a of the case. The camera cover 6 is fixed to the case 2, and the panel 10 is fitted to the case 2 in which these are incorporated so as to cover the case 2.

The camera holder tilt bar 42 is slidably fitted to the tilt bar receiver 52 and swings the camera holder 4 with the camera holder rotation shaft 41 as a pivot shaft.
[0014]
Further, the tilt shaft 5 is provided with a tilt adjustment concave portion 55 on the outer peripheral portion of the tilt shaft bending portion 53, and the case 2 is provided with a tilt adjustment convex portion 21 that meshes with the tilt adjustment concave portion 55, and when the tilt shaft 5 rotates. Tilt adjustment can be performed in stages by tilting the tilt shaft flexure 53 and meshing with the next tilt adjustment recess 55.
[0015]
Further, the rotation radius 5b of the tilt shaft rotary rod 54 that is directly tilted by the tilt knob 3 is increased with a small force as compared with the rotation radius 5a of the tilt rod receiver 52 of the tilt shaft 5 that holds the camera holder 4. Can be tilted and the camera holder 4 can be held. It should be noted that the rotation radius of the tilt shaft rotating rod 54 is preferably increased to 2 to 3 times the rotation radius of the tilt rod receiving 52 of the tilt shaft 5. This is because the present inventor has confirmed that the most suitable when the tilt operation is performed with a small force is when the rotation radius of the tilt shaft rotary rod is 2 to 3 times the rotation radius of the tilt rod receiver. It is.
[0016]
The tilting operation by the tilt structure of the camera-equipped entrance machine will be described.
[0017]
When the tilt knob 3 is slid in any of the upper and lower directions to tilt the camera 9 of the camera-equipped entrance machine, the rotary rod receiver 31 moves the tilt shaft 5 through the tilt shaft rotary rod 54 of the tilt shaft 5. For example, as shown in FIGS. 3 (a) and 3 (b), since it is rotated clockwise around the tilt shaft rotating shaft 51, the tilt bar receiver 52 provided on the tilt shaft 5 is slidable. The camera holder 4 can be rotated in the counterclockwise direction with the camera holder rotation shaft 41 as a pivot shaft via the fitted camera holder tilt bar 42. Further, as shown in FIGS. 3A and 3C, when the tilt knob 3 is rotated counterclockwise around the tilt shaft rotation shaft 51, the camera holder 4 can be rotated clockwise.
