Description
- The present invention relates to an operating device configuring an operating unit provided in an electronic apparatus.
- In recent years, an operating button structure independent of an operating unit is widely used in an operating panel of an electronic apparatus such as an audio equipment, a video equipment, and home electric appliances such as a microwave oven.
- As a generally known independent operating button structure, there is a structure in which a plurality of buttons are disposed in separated positions from one another, or a structure in which a plurality of buttons are arranged laterally and in parallel with one another without gaps (for example, see Patent Document 1). In the button structure in which the buttons are disposed in the separated positions, the use of an integral molded resin for the buttons can comparatively easily solve a problem in an external appearance, for example, a parallelism of the button.

In a lowermost stage, only two operatingbuttons 11 are laterally arranged, and the protrudingportions 16 are formed close to a center of the two operatingbuttons 11. - Referring to the operating device having the structure described above, attachment thereof will be described below.
- As shown in
Fig. 4 , the integrally-formedoperating buttons 11 are inserted into the operating button inserting openingportions 18 from a rear side to a front side of the operatingunit 12. At this time, the protrudingportions 16 formed integrally with the operatingbuttons 11 butt theperipheral edge portion 17 of the operating button inserting opening portion 18 (the protrudingportions 16 contact the peripheral edge portion 17). - The operating
buttons 11 having the hinge mechanisms formed thereon are necessarily moved rearward (a right direction inFig. 4 ) (the operatingbuttons 11 are pushed rearward by the peripheral edge portion 17). As described above, the operatingbuttons 11 are separately movable, respectively. Therefore, the center side of theoperating button 11 is moved (rotated) rearward around an end side of theoperating button 11. - In a view showing a state in which the
operating buttons 11 are laterally arranged, theoperating button 11 in the vicinity of the rib-shaped protrudingportion 16 provided in a line with the operatingbuttons 11 is moved (rotated) rearward by a height of the protrudingportion 16. Consequently, the gap between the operatingbuttons 11 laterally arranged is reduced as compared with that in the molding. - Moreover, the heights of the protruding
portion 16 and theperipheral edge portion 17 are set such that frontward protrusion heights of the operatingbuttons 11 are almost equal to one another. Consequently, the protrusion heights of surfaces of the operatingbuttons 11 are coincident with one another, and unevenness is eliminated, whereby beauty of an external appearance can be enhanced. - The
operating button 11 and theperipheral edge portion 17 of the operatingunit 12 are close to each other so that the gap is reduced, whereby water hardly enters into the operatingboard 14 from the operating button insertingopening portion 18. Consequently, it is possible to prevent a malfunction. - Referring to the operating device having the structure described above, an operation and effect thereof will be described below.
- When the
operating button 11 supported on the operatingunit 12 is pressed down, the operatingswitch 13 using the tactile switch provided on an opposing surface is turned ON. The operatingsubstrate board 14 provided with the operatingswitch 13 transmits the signal to the IC (not shown) by the operatingboard 14, and control is performed. - As described above, according to the embodiment, in the
operating panel 30 including theintegral operating buttons 11 laterally arranged without a gap, the protrudingportions 16 formed integrally with the operatingbuttons 11 butt theperipheral edge portion 17 of the operating button insertingopening portion 18 of the operatingunit 12. Therefore, one end of theoperating button 11 can move rearward, whereby it is possible to reduce the gap between theadjacent operating buttons 11. Consequently, the operatingbuttons 11 laterally arranged do not need to be independent buttons, whereby it is possible to reduce the number of components and to enhance an assembling property. - Although the embodiment has describes an example in which the operating device according to the invention is applied to a microwave oven as an electronic apparatus, the invention is not limited to the microwave oven and may be applied to uses in the field possessing an operating device which performs electronic control.
- Although the invention has been described in detail with reference to the specific embodiment, it is apparent to the skilled in the art that various changes or modifications may be made within the scope of the invention as defined by the claims.
- It is referred to Japanese Patent Application (No.
2011-181239) filed on August 23, 2011 - The operating device according to the invention relates to an optimum shape of the operating buttons as described above, and is applicable to uses in the field possessing an operating device having the similar button layout.

Claims (3)
- An operating device comprising:an operating board (14) for controlling an electronic apparatus;an operating unit (12) disposed on an operation side of the operating board (14) for supporting the operating board (14);a plurality of operating buttons (11) supported on the operating unit (12) and connected linearly;operating switches (13) provided on a surface of the operating board (14) opposing the operating buttons (11);an opening portion (18) formed on the operating unit (12) for placing the operating buttons (11) ;characterized in thatit further comprisesa peripheral edge portion (17) which protrudes toward the operating buttons (11) around the opening portion (18), and in thatbuttons at ends of the plurality of linearly connected operating buttons (11) comprise protruding portions (16) having tips which contact the peripheral edge portion (17) to intentionally bend the plurality of linearly connected operating buttons (11) into a bow shape, thereby reducing a gap between adjacent buttons of the operating buttons (11).
- The operating device according to claim 1,
wherein the plurality of linearly connected operating buttons (11) are previously formed to be uneven in conformity with a shape of the plurality of linearly connected operation buttons (11) bent into the bow shape such that the protrusion heights of surfaces of the operating buttons (11) are coincident with one another in a state in which the adjacent protruding portions (16) of the buttons are bent into the bow shape. - The operating device according to claim 1 or 2,
wherein a plurality of combinations of linearly connected operating buttons (11) each comprising at least two operating buttons laterally arranged are integrally formed in a longitudinal direction.
