Abstract

<P>PROBLEM TO BE SOLVED: To provide a tilt mechanism which is simplified in structure and therefore is easy to assemble and which never has decline in rotary body holding force over time. <P>SOLUTION: A magnet 32A is attached to a rotary shaft 31A of a display portion 26, and a metal piece 33A is arranged at a position opposite to an end face F of the rotary shaft 31A. A little movement in the axis line direction is allowed for the rotary shaft 31A, and the magnet 32A attached to the end of the rotary shaft 31A is attracted to the metal piece 33A by its magnetic force and stuck to it. As a result, frictional force between the magnet 32A and the metal piece 33A becomes frictional torque and the display portion 26 is held in any posture. Thus, since the posture of the display portion 26 is held via magnetic force, there is extremely low risk that frictional torque for maintaining the posture of the display portion 26 decreases over time. Moreover, the device can be simplified in structure, which allows the device to be assembled easily. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to an attitude holding device for a rotating body that holds an attitude of a rotating body, such as a liquid crystal monitor, provided rotatably with respect to an apparatus body such as an electronic device with respect to the apparatus body. The present invention also relates to a recording apparatus typified by a facsimile or a printer, which includes the rotary body posture holding apparatus.

  There are various types of electronic devices in which a display device such as a liquid crystal monitor is provided so as to be rotatable with respect to the apparatus main body. For example, in a notebook computer, a word processor, or in recent years, an image or print to be recorded in an inkjet printer. A small liquid crystal monitor that displays setting information and the like is provided to be rotatable with respect to the printer main body.

Such a display device is attached to the main body via a so-called tilt mechanism, and can maintain a posture (angle) with respect to the device main body in a desired state. Such conventional tilt mechanisms are described in, for example, Patent Documents 1 to 5.

  One of the technical principles of holding the display device, that is, the rotating body in the conventional tilt mechanism in the conventional tilt mechanism is to apply a torque (friction torque) to the rotating shaft of the rotating body by using a frictional force. Is held in an arbitrary posture (friction mechanism: see, for example, Patent Documents 2, 4, and 5).

  However, since the conventional friction mechanism is configured to apply a friction torque to the rotating shaft of the rotating body using a spring force, the configuration is easily complicated and the assembly of the apparatus is not easy. In addition, when it is configured to obtain the spring force by elastic deformation of the resin material, thereby avoiding complication of the configuration, it is difficult to obtain a desired magnitude of friction torque, and with temperature change and time change There was a drawback that the friction torque would change.

And assembly of the device can be facilitated. Further, since the friction surface is located at a position away from the rotation center of the rotation shaft 31D, a larger friction torque can be generated, and a large area of the friction surface can be efficiently secured in a small space.

Although only pivotally supported, it may be configured such that friction torque is applied to either of the two rotating shafts by disposing the posture maintaining means 30D on the other rotating shaft. The same applies to the first to third embodiments.

  Further, in this embodiment, the pedestal 37 is formed of a metal material, but the pedestal 37 may be formed of a magnet having a polarity different from that of the magnet 32D. Thereby, an even stronger friction torque can be obtained. The same applies to the first to third embodiments, and an even stronger friction torque can be obtained by the attractive force between the magnets.

  The magnet 32D does not directly contact the concave surface 37a of the pedestal 37. For example, when the magnet 32D is provided integrally with the rotary shaft 31D by insert molding, a resin layer is formed on the surface of the magnet 32D, and the pedestal is interposed via the resin layer. 37 may be in contact with the concave surface 37a. Thereby, wear of magnet 32D can be prevented. The same applies to the first to third embodiments.

  The friction torque can be controlled by using the friction member as used in the second embodiment, and selecting the material (that is, the friction coefficient), and the friction coefficient adjusting material such as oil on the friction surface. It can also be performed by interposing.
