Embodiment Construction

[0034] will refer to Figure 1 to Figure 7 A rotatable operating device according to a first embodiment of the present invention will be described.

[0035] Figure 1 to Figure 3 The illustrated rotatable operating device is arranged in a place inside an automobile or the like, and, when it is subjected to a rotational operation, outputs a detection signal corresponding to the rotational direction and the rotational amount of the rotation. This rotatable operating device is provided with: a rotatable operating member 10 that performs rotation; a pawl mechanism 12 ( figure 2 with image 3 ); and a rotation detection switch 14 that detects the rotation direction and the rotation amount of the rotatable operation member 10 .

[0036] The rotatable operating member 10 is provided with a rotary knob 16 , a click generating portion 18 and a plurality of switch driving portions 20 . Such as figure 1 As shown, the rotatable operating member 10 is supported by a panel 22 or by a...

Abstract

Disclosed is a rotating-manipulation device provided with a rotating-manipulation member (10), and a rotation detection switch (14) that detects the direction and amount of the rotating-manipulation, wherein the rotation detection pitch of the rotation detection switch (14) can be reduced while assuring normal operation thereof. The rotating-manipulation member (10) comprises a plurality of switch driving sections (20) arranged in the circumference direction thereof. The rotation detection switch (14) comprises a detector (30); and a switch body (32) that holds the detector (30) movable in a first moving direction and a second moving direction, which are opposite directions of each other with respect to a prescribed origin position, and outputs a detection signal each time the detector (30) moves. The rotation detection switch (14) is arranged so as to take a posture that makes the moving direction of the detector (30) nearer to an orthogonal direction with respect to the rotating circumference direction of the rotating-manipulation member (10), rather than the rotating circumference direction thereof. Each of the switch driving sections (20) has a shape that moves the detector (30) for a prescribed distance or more in the first moving direction or the second moving direction, in accordance with the rotation of the rotating-manipulation member (10), and then releases the detector (30).

Description

technical field [0001] The present invention relates to a rotatable operating device arranged on a panel or the like inside an automobile. Background technique [0002] Generally, a rotatable operating device arranged at a position inside an automobile or the like includes: a rotatable operating member capable of rotating while being gripped by fingers, for example; The detection signal corresponding to the direction of rotation and the amount of rotation. Although it is possible to use a rotary encoder as the detection means, such rotary encoders are usually expensive and therefore, the possibility of using other means, such as cheap switches, to detect the rotation is being investigated. [0003] Traditionally, known as Figure 14 A rotatable operating device using a switch is shown (Patent Document 1). This device includes: a rotatable operation member 80 that performs rotation; and a rotation detection switch 84 for detecting the rotation. [0004] The rotatable opera...
