Description

[Detailed explanation of the idea] (b) Industrial application fields The present invention relates to an opening/closing mechanism for an operating part of an electronic device.

(B) Prior Art A video tape recorder prevents erroneous operation by exposing frequently used operation buttons on the front panel and covering less frequently used operation buttons with an opening/closing lid that forms part of the front panel. ing. The operation panel with operation buttons disposed inside the opening/closing lid is normally arranged upright below the front panel, and the operating method is displayed on the back side of the opening/closing lid. However, it is difficult to operate the operation buttons on the operation panel, which is arranged below the front panel and set back from the opening/closing lid.

Therefore, the 83rd to
As disclosed on page 84, the operation panel is integrated into the opening/closing lid, and when the opening/closing lid is opened, the operation surface is positioned diagonally, and the operation method is displayed on the narrow operation panel. A mechanism is disclosed. However, in this conventional example, since the operation panel is built into the opening/closing lid, the operation panel penetrates deep when the lid is closed, which not only requires sufficient space for opening and closing, but also the width of the operation section is narrow, limiting display space. It was done.

(c) Purpose of the invention Therefore, in view of the above-mentioned points, the present invention proposes an operation part opening/closing mechanism that positions the operation panel diagonally when the opening/closing lid is opened and also compactly stores the operation panel by opening and closing the opening/closing lid. It is something to do.

(d) Structure of the invention The present invention has an operating unit whose upper end is pivotally supported on a base, and which guides the lower end of the operation unit forward in conjunction with the opening of the opening/closing lid, and has one end pivotally supported on the end of the opening/closing lid. The present invention is characterized in that the display panel is urged into contact with the lower end of the operation section.

(E) Embodiment The present invention will be described below with reference to an illustrative embodiment.

The figures all show this embodiment, with Fig. 1 showing a side sectional view when the lid is closed, Fig. 2 a side sectional view when the lid is open, and Fig. 3 an overall perspective view when the lid is open. Was.

As is clear from both figures, the operating part 2 on which the push buttons 1 and 1 are arranged has shaft parts 3 formed on both sides of the rear part of the upper end fitted into the through holes of the chassis (base) 4, and The shaft portions 5 formed on both sides of the opening/closing door 6 are loosely fitted into the long holes 8 of the side walls 7 of the opening/closing door 6.

Further, the opening/closing lid 6 has a front panel 9 on the front side.
A pair of projections 10 formed on a front panel 9 fixed to the chassis 4 are fitted into through holes 11 on both sides, respectively.
Therefore, the opening/closing door is supported so as to be rotatable about the protrusion 10 in two positions: the closed position shown in FIG. 1 and the opened position shown in FIG. Moreover, this opening/closing lid 6 also has a first pivot 12 and a second pivot 13 formed at its upper end.
The first pivot 12 pivotally supports one end of the display panel 14, and the second pivot 13 is provided with a spring 15 that urges the display panel 14 to rotate in the counterclockwise direction in the figure.

Therefore, when the opening/closing lid 6 is in the closed state, the display panel 14 comes into contact with the protruding sides 16 formed higher than the operation buttons 1 on both sides of the operation section 2, and the springs 1
It is forced to rotate clockwise against the bias of 5. Therefore, the operation buttons 1, 1 do not come into contact with the display panel 14 due to the opening/closing operation of the opening/closing lid 6.

Furthermore, when the opening/closing lid 14 is opened from the closed state shown in FIG. 1, the shaft portion 5 loosely fitted in the long hole 8 rotates clockwise, causing The part 2 is rotationally guided forward. Also,
The display panel 14 is rotated by the urging force of the spring 15, and its rotation in the counterclockwise direction is restricted by a regulating protrusion 17 formed on the inside of the side wall 7 of the opening/closing lid 14. Clockwise rotation is also restricted by a restricting side 18 formed protruding from the lower end of the portion 2. Therefore, the display panel 14 is fixed in position in the open state shown in FIG.

The display panel 14 is for displaying the operation procedure of a large number of push buttons necessary for making timer recording reservations and setting the real time. In addition, the opening/closing lid 6
has a moderation mechanism (not shown) disposed on the outside of the side wall 7, and is selectively locked in the closed position and the open position, respectively.

(f) Effects of the invention Therefore, according to the present invention, compared to the conventional example in which the operating section is incorporated into the opening/closing lid, not only can a sufficient display space be secured, but also less storage space is required, which has great effects.
