Problems solved by technology

[0008] The hinge device described in the aforementioned Patent Document 1 is configured to hold the oscillating body at a predetermined angle by frictional resistance in the rotational direction applied to the second gear portion. Therefore, when the oscillating body is displaced from the second position to the first position, The oscillating body may return slightly from the first position to the second position side due to the reaction force caused by the frictional resistance applied to the second gear part
[0009] In particular, in the hinge device configured to store the swing body in the storage portion formed in the support member when the swing body is in the first position, there is a problem that the swing body displaced to the first position is moved from the first position to the second position. In the case of side return, since the swing body protrudes from the storage part, the appearance is deteriorated

[0042] Such as Figure 2 ~ Figure 6 As shown, the hinge device 6 includes a support member 20 , a swing body 60 , a first gear portion 61 , and a second gear portion 70 .

[0043] The supporting member 20 is attached to the upper surface of the housing 2 . The swing body 60 is supported by the support member 20 so as to be rotatable around the rotation axis 60a. The first gear portion 61 is provided on the swing body 60 and is configured to be rotatable integrally with the swing body 60 around the rotation axis 60 a. The second gear unit 70 is supported by the support member 20 and is configured to be able to mesh with the first gear unit 61 . The rotation axis 60a extends in the left-right direction. The first gear unit 61 is an example of a first gear.

[0044] The support member 20 has a storage portion 21 whose upper surface is open so as to accommodate the swing body 60 , and a support groove portion 22 that supports the second gear portion 70 .

[0045] The swing bo...

no. 2 approach

[0092] The hinge device 6 can also be configured as follows.

[0093] Such as Figure 8 As shown, the hinge device 106 of this embodiment is different from the hinge device 6 of the first embodiment in that the first gear part 61 is provided on the support member 120 and the second gear part 70 is provided on the swing body 160 .

[0094] The support member 120 is attached to the upper surface of the housing 2, and the swing body 160 is supported by the support member 120 so as to be rotatable around the rotation axis 160a. The swing body 160 is configured to rotate about the rotation axis 160a so that it can be at the first position ( Figure 8 The position shown in (c)) and the second position ( Figure 8 (a)), wherein the first position is a position close to the support member 120 and is accommodated in the storage portion 121, and the second position is a position away from the support member 120.

[0095] The support member 120 has a storage portion 121 whose upper su...

no. 3 approach

[0104] The hinge device 6 can also be configured as follows.

[0105] The hinge device 206 of this embodiment is mainly configured such that the second gear part 270 can be displaced in a direction in which the rotation axis 260a and the rotation axis 270a approach and move away from each other, and the disengagement part has an approach spring 224 and a cam member 262, which is different from that of the first embodiment. The hinge arrangement 6 is different.

[0106] Such as Figure 9 , Figure 10 As shown, in the hinge device 206 of this embodiment, the first gear part 261 is provided on the swing body 260 , and the second gear part 270 is provided on the support member 220 . The first gear unit 261 is an example of a first gear.

[0107] The support member 220 is attached to the upper surface of the housing 2, and the swing body 260 is supported by the support member 220 so as to be rotatable around the rotation axis 260a.

Abstract

Provided are a hinge device and an image forming device. The hinge device includes: a support member; a swing body supported by the support member so as to be rotatable around a rotation axis, and the swing body is configured to be able to move away from a first position and away from the first position. The support member swings between the second positions; the first gear is arranged on one of the support member and the swing body; the second gear is arranged on the support member and the swing body. On the other side of the oscillating body, the second gear is configured to rotate by the oscillating body in a meshed state with the first gear; and a friction member is configured to move toward the first gear. The two gears apply frictional resistance in the direction of rotation; and a disengagement part configured to disengage the first gear and the second gear when the oscillating body is in the first position.

Description

technical field [0001] The present invention provides a hinge device and an image forming apparatus capable of holding a oscillating body at an arbitrary angle, and the oscillating body is supported by a supporting member so as to be able to swing. Background technique [0002] Conventionally, a hinge device is known, which includes: a support member; and a swing body that is rotatably supported by the support member around a rotation axis and that can be supported at a first position and away from the first position. The part swings between the second positions, and the hinge device is configured as a so-called free stop hinge capable of holding the oscillating body at any angle relative to the supporting part. [0003] As such a hinge device, as shown in Patent Document 1, for example, it includes: a first gear part provided on the swing body; a second gear part provided on the support member and connected to the first gear The two gear parts are meshed with each other, a...
