Abstract

<P>PROBLEM TO BE SOLVED: To provide a two-step click type push-button which is small-sized and inexpensive and which can give a sense of click respectively at the first step and the second step. <P>SOLUTION: A skirt part 12 is installed which spreads diagonally downward from the peripheral edge of a push-down receiving part to receive a push-down operation so as to surround the push-down receiving part 11, and which gives the sense of click because the push-down receiving part 11 is deformed at a timing of being pushed down by only a prescribed first stroke. Furthermore, the outer peripheral part 13 which spreads from the peripheral edge of the skirt part in the nearly horizontal direction so as to surround the skirt part 12 is installed. By being mounted to an equipment in a deformed state in which the center part is raised while its outer peripheral part is compressed from both sides, the push-down receiving part releases float rise above the outer peripheral part at the timing of being pushed down by a shallower second stroke than a prescribed first stroke, and gives the sense of click of the first step. Furthermore, when the push-down receiving part is further pushed down, the sense of click of the second step is given by deforming the skirt part. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a two-click click button that is attached to a device and provides a click feeling in two steps when pressed, a device including the two-click button, and a camera corresponding to one of the devices.

  The price, size and performance of compact cameras are increasing. Among them, the structure of the shutter button is also cheap and must be miniaturized, but some compact cameras operate the distance measuring device in synchronization with the operation of the shutter button before the shutter is released. In such a compact camera, a two-stage click-type push button that provides a click feeling in two stages is required as a shutter button. Normally, when such a two-click type push button is incorporated into a device such as a compact camera, an elastic member in which a large number of one-step click type push buttons and two-stage click type push buttons are integrally formed is provided in order to reduce the cost. Used.

  FIG. 1 is a view showing the structure of an elastic member in which these click-type pushbuttons are integrally molded.

  A two-stage click-type push button 31 is formed on the leftmost side of the elastic member shown in FIG. 1, and a one-stage click button 32 is formed on the right side of the two-stage click-type push button 31.

  FIG. 1 shows the structure of the lower surface of the press receiving portion of the click type push buttons 31 and 32 that are pressed from the back side of the paper.

  A second switch 33a made of a boss is provided at the center of the lower surface of the press receiving portion 31a of the two-stage click type push button 31 shown in FIG. 1, and the second switch 33a is centered on the second switch 33a. A first switch composed of three bosses 34a to 34c is provided so as to surround. The height of the central boss 33a serving as the second switch is lower than the heights of the three bosses 34a to 34c serving as the first switch. When the receiving part is pressed down, the first contact point is first pressed by the first switch composed of the three higher bosses 34a to 34c, and when the pressing part is further pressed down, the height is low. The second stage contact is pushed by the second switch comprising the boss 33a. In this way, when the first switch is pressed by the first switch, the elastic member is deformed to give the user a click feeling at the first step, and when the press receiving portion is further pressed, The elastic member is further deformed at the timing when the second-stage contact is pushed by the second switch composed of the low boss 33a, and the second-stage click feeling is given. However, the press receiving portion 31 is deformed once in this way, and the first step click feeling is given by the deformation, and the press receiving portion 31 is further deformed by pushing in the same direction, and the second step is obtained by the deformation. Even if it tries to give a click feeling, it is difficult to give the user a click feeling as expected in the second stage.

  Giving the user a click feeling at both the first and second stages of such a two-stage click push button is very important for the device to which the two-stage click push button is attached. If it is not possible to give the user a click feeling separately in both the second stage, the user determines whether the first and second stage pressing operations of the two-stage click-type pushbutton have been performed properly. I can't. In particular, in a camera to which this two-stage click-type pushbutton is applied as a shutter button, if the user does not feel the second-stage click feeling, the user pushes the second-stage press operation more than necessary. Will occur and camera shake will occur.

Therefore, in order to prevent this camera shake, a structure of a two-stage click-type push button capable of obtaining a click feeling in both the first stage and the second stage has been proposed (for example, see Patent Document 1). In the two-stage click-type pushbutton described in Patent Document 1, the skirt portion has a two-stage structure, and the first and second skirts are deformed in accordance with the pressing operation by changing the first and second skirts. Each click gives a click feeling. However, if a skirt portion having a two-stage structure is provided as in this Patent Document 1, the two-stage click type push button itself is enlarged, and the equipment on the side where the enlarged two-stage click type push button is disposed. However, there is a problem that the size is increased.

It is possible to have a structure that gives a click feeling to the eyes.

  Further, a first contact point that presses a first-stage contact provided on the device at a timing when the pressing receiving portion is pressed by the second stroke on the lower surface of a portion that is compressed from both sides of the outer peripheral portion and floats upward. It is desirable to have a second switch portion that pushes a second contact provided on the device at a timing when the push receiving portion is pushed by the first stroke.

  Then, when the first contact is pressed by the first switch at the timing when the press receiving portion is pressed by the second stroke shallower than the first stroke, the floating at the center of the outer peripheral portion is eliminated. When the first stage click feeling is given to the user, and the second contact point is pushed by the second switch part when the push receiving part is pushed by the first stroke. The skirt portion is deformed to give the user a second click feeling.

  Furthermore, it has a pair of attachment parts that are provided on both sides of the outer peripheral part in a direction in which the outer peripheral part is compressed, and that can be attached to the device while the outer peripheral part is compressed from both sides. Is preferred.

  Then, it can be easily attached to the device while the outer peripheral portion is compressed by the pair of attachment portions, and the structure for compressing the elliptical portion from both sides is not provided on the device side. A structure that provides a click feeling at the stage is realized.

  Here, it is preferable that the two-stage click type push button is integrally formed of rubber.

  Since the skirt part is not composed of two stages as in the past, the structure of the two-stage click type push button is simplified. The effect of being able to be drawn out.

In addition, the device of the present invention that achieves the above-described problem is a device including a two-stage click-type push button that gives a click feeling to the second stage in response to pressing.
