  As shown in FIGS. 10A and 10B, the cursor key 8 (first operation unit) includes an operation unit 8a (first operation unit), support units 8b and 8h, openings 8c, 8d and 8f, The frames 8m and 8n (first frame) and the button 10 are integrated. The cursor key 8 is configured by plating the surface of a base material made of ABS resin or the like. The plating process is applied to at least a part of the surface of the cursor key 8 in order to decorate the base material and prevent corrosion.

  The operation portion 8a is a portion exposed to the outside through the opening 21p of the back unit 21, and characters and marks indicating a predetermined function are written on the surface (pressing portion). In the present embodiment, a triangular mark indicating the up / down / left / right direction is described. However, a character or mark (such as a self-timer mark) indicating a specific function may be described. The cursor key 8 built in the imaging device is provided with a switch 27 (see FIG. 4) below the operation unit 8a. When the operation unit 8a is operated by a user, the cursor key 8 is switched by the back surface of the operation unit 8a. 27 is pressed.

  The pins 8x and 8y are erected on the back surface of the cursor key 8 as shown in FIG. 10B. Further, the long holes 9b and 9c of the button 9 are engaged with the pins 8x and 8y. The engagement holes 8v and 8w are engaged with the protrusions 9v and 9w of the button 9. Thereby, the button 9 can be held by the cursor key 8.

  The openings 8c and 8f are formed at positions facing each other with the operation portion 8a interposed therebetween, and are engaged with pins 21s and 21t formed on the rear unit 21, thereby determining the positions.

  The opening 8d is for exposing the button 9 to the outside, and has a size that allows at least the operation portion 9a of the button 9 to be operated with a user's finger.

In FIG. 10B, the part which has attached | subjected area | region hatching is a part which is not plated and the base material is exposed. The portion that has not been plated is less rigid than the portion that has been plated because there is no plating film. In this way, by forming portions that are not plated on the frames 8m and 8n that are elastically deformed when the cursor key 8 is pressed, the rigidity of the frames 8m and 8n is reduced, so that the frames 8m and 8n are easily elastically deformed. The operability of the key 8 can be improved. In addition, since the plating process is omitted as described above to facilitate elastic deformation, the entire length of the frames 8m and 8n can be shortened while ensuring operability. By forming the frames 8m and 8n short, the cursor key 8 can be miniaturized and the imaging device can be miniaturized.

  Further, the frames 8m and 8n are not arranged in the radial direction of a portion (for example, a triangular mark in FIG. 10A) to be operated by the user in the operation unit 8a. That is, the frames 8m and 8n may be arranged at positions that do not overlap with a straight line passing through two opposing triangle marks among the four triangle marks shown in FIG. 10A. In the present embodiment, the frame 8m is arranged between a part that can be operated in the upward direction and a part that can be operated in the right direction in the operation unit 8a. In addition, the frame 8n is disposed between a part that can be operated in the left direction and a part that can be operated in the downward direction in the operation unit 8a. That is, when the operation unit 8a is pressed by the user, the operation unit 8a is mainly displaced with the frames 8m and 8n as axes, so a line connecting the frames 8m and 8n is a displacement axis of the operation unit 8a.

  The pins 8p are erected at four positions on the back surface of the operation portion 8a. The pin 8p is formed at a position facing each of the plurality of buttons constituting the switch 27 (see FIG. 4). Accordingly, when the operation portion 8 a is pressed, the pin 8 a formed on the back surface of the pressed portion presses at least one button of the switch 27. Even if the pin 8a is not formed, the switch 8 can be pressed on the back surface of the operation portion 8a, and therefore the pin 8p is not essential.

  The cursor key 8 having the above configuration is positioned on the back surface of the back unit 21 by positioning the pins 21s and 21t formed on the back unit 21 in the openings 8c and 8f. At this time, the surfaces of the frame 8m and the rib 8g are in contact with the back surface of the back unit 21, and the cursor key 8 in an unused state is held substantially horizontally. The operation unit 8a is exposed to the outside through the opening 21p, and the button 10 is exposed to the outside through the opening 21q.

  Next, as shown in FIG. 11, the button 9 (second operation unit) includes an operation unit 9a (second operation unit), long holes 9b and 9c, and frames 9d and 9e (second frame). And.

  The operation unit 9a can move in the vertical direction, and the user can operate the switch 27 (see FIG. 4) disposed at the lower part of the operation unit 9a by pressing the upper surface by the user.

  The frames 9d and 9e are arranged at opposite positions in the operation unit 9a and extend in opposite directions. That is, when the operation part 9a is pressed by the user, it is mainly supported by the frames 9d and 9e and displaced. The positions where the frames 9d and 9e are arranged on the operation unit 9a are as follows. The cursor key 8 and the button 9 are assembled to the rear unit 21 as shown in FIG. And the line segment connecting 9e are substantially orthogonal to each other. That is, in the state where the cursor key 8 and the button 9 are assembled as shown in FIG. 15, the frames 8m, 8n, 9d and 9e are symmetrical with respect to the center axis of the button 9 in a rotation direction of about 180 °. It is arranged at the position.

  The long holes 9b and 9c are formed near the tips of the frames 9d and 9e. The long holes 9b and 9c are held (temporarily fixed) by the cursor key 8 when the pins 8x and 8y formed on the cursor key 8 are engaged. When the button 9 is held by the cursor key 8, the operation unit 9a is disposed in the opening 8d, and the operation surface is exposed to the outside. The long holes 9b and 9c and the pins 8x and 8y can be connected by a method of engaging both as in the present embodiment or by heating both or one of the long holes and the pins to weld them together. There are a method, a method of adhering both by an adhesive, and the like.

  When combining the cursor key 8 and the button 9, first, the button 9 is arranged on the back surface of the cursor key 8 so that the operation unit 9a is exposed through the opening 8d. Next, the engagement hole 8v and the protrusion 9v are engaged, and the engagement hole 8w and the protrusion 9w are engaged. Next, the pin 8x is engaged with the long hole 9b, and the pin 8y is engaged with the long hole 9c. Thereby, the unit of the operation unit is completed.

  In the above configuration, when the operation unit 8a of the cursor key 8 is pressed by the user, the frame 8m and 8n are displaced in the twisting direction. And the switch 27 (refer FIG. 4) arrange | positioned under the cursor key 8 is pressed by the pin 8p currently formed in the back surface of the operation part 8a.

  When the operation unit 9a of the button 9 is pressed, the button 9 is displaced in the pressing direction, and the switch 27 (see FIG. 4) is pressed by the back surface of the operation unit 9a.

  Here, the cursor key 8 and the button 9 are arranged so that the displacement axis of the operation unit 8a and the displacement axis of the operation unit 9a are substantially orthogonal to each other, and do not overlap with the triangular mark of the operation unit 8a. Therefore, even if the operation unit 8a is operated in any of the upper, lower, left and right directions, the operation unit 9a is not displaced and no erroneous operation occurs. Further, even if the operation unit 9a is pressed, the operation unit 8a is not displaced and no erroneous operation occurs.

  Further, since the two buttons 10 are independently and integrally arranged on the frame 8n, they can be operated independently.
