BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a retractable operation panel device constructed so that a panel surface provided with operation switches can be protruded and retracted with respect to the surface of a housing as required. is there.

[0002]

2. Description of the Related Art In the case of, for example, an operation panel of an audio device or a television receiver, in order to avoid complication of appearance, switches which are relatively infrequently used are mounted on a panel which is built into and retracted from a main body. May be provided. As one example of such a retractable operation panel, a drawer type that slides back and forth is disclosed in
No. 3,278,81. As an operation panel having a different configuration, a movable member provided with operation switches is pivotally supported inside the housing so as to be rotatable around its lower end. 124
No. 708.

[0003]

[Problems to be solved by the invention] These conventional structures are:
In both cases, the displacement amount of the operation panel portion from the storage position to the use position is large, and therefore, a lead wire for electrically connecting a contact of a switch provided on the operation panel to a circuit incorporated in the main body, or There is a problem that the amount of deformation of the flexible substrate or the like tends to be excessive, and the connection portions thereof are easily disconnected. Further, in order to prevent the panel surface from rattling due to the operation of pressing the operation button at the time of projection, another holding means must be provided.

The present invention has been devised to solve such disadvantages of the prior art, and its main purpose is to reduce the amount of movement of the panel itself and to operate the panel without separately providing a holding member or the like. It is an object of the present invention to provide a retractable operation panel device capable of preventing a panel from closing or wobbling by force.

[0005]

According to the present invention, it is an object of the present invention to provide a retractable operation panel device which is constructed so as to be able to protrude and retract from a storage portion formed in a main body, the outer surface of which is provided in the front. And a lid 5 pivotally attached to a member on the main body side so as to be able to perform a pivoting movement including a vertical movement between a vertical position facing the main body and a horizontal position where the outer surface thereof faces downward. Formed and coaxial with the center of rotation of the lid.
A first arm 6 that pivots with the first arm,
Long and spaced horizontally from the inner surface of the lid
A second arm 8 rotatable about a pivot 7 at a certain distance from the pivot 4 of the lid, and an operation panel 9 connected to each free end of the first and second arms. This is achieved by providing the retractable operation panel device 1 having the following features.

[0006]

According to this structure, the operation panel
Move the rear end movement amount smaller than the front end movement amount.
Can be Therefore, the lead wire
, The amount of movement of the joint of the lead wire is small.
And lead wires can be shortened.
Acts on the wiring connection due to the operation of the operation panel
Stress can be reduced. Moreover, by appropriately setting the relationship between the arm angle and the operation direction when the operation panel protrudes, it is possible to prevent the panel from being unnecessarily displaced by the operation force.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction of the present invention will be described in detail below based on specific embodiments shown in the accompanying drawings.

FIG. 1 shows an operation panel device 1 according to the present invention.
Is applied to the television receiver 2. The operation panel device 1 is configured to be able to be stored in a lower part of a receiver main body.

As shown in FIGS. 2 and 3, the operation panel device 1 has a pivot 4 at a position offset inward of the housing 3 and a position in which the outer surface thereof is in a vertical state (FIG. 2). A lid 5 capable of pivoting between a pivoted and horizontal position (FIG. 3) and a first arm 6 extending from a pivot of the lid 5 in a direction away from the inner surface of the lid 5; , Extending in substantially the same direction as the first arm 6, and having its pivot 7 located on the same horizontal plane as the center of the pivot 4 of the lid 5.
And an operation panel 9 connected to the free ends of the first and second arms 6 and 8 and provided with operation switches on the upper surface thereof.

A connecting line 10 formed of a flexible printed board or the like extends from a rear end of the operation panel 9 toward a circuit board (not shown) of the main body.

Although not shown in the drawing, the operation panel device 1 has an opening direction urging mechanism using a known spring means, a viscous damper mechanism for regulating the opening direction moving speed,
And a latch mechanism for maintaining the closed state is provided around the pivot 4 of the lid 5 so that the stored state is normally maintained and the operation surface of the operation panel 9 can be exposed by a so-called one-touch operation. Has become.

When the latch mechanism (not shown) is released, the lid 5 pivots downward about the pivot 4 and moves from the vertical state shown in FIG. 2 to the horizontal state shown in FIG. Then, the first arm 6 integrated with the lid 5 rotates, and accordingly, the operation panel 9 whose rear end side movement trajectory is restricted by the second arm 8 protrudes forward with an arc movement. . As a result, the opening 1 after the lid 5 has moved downward
1 allows access to the operation surface of the operation panel 9.

As can be seen from FIGS. 2 and 3, the second arm 8 located inside the housing 3 is longer than the first arm 6, so that the The moving amount of the rear end is smaller than the moving amount of the front end. Accordingly, the amount of movement of the connection portion of the connection line 10 is also reduced, so that not only the connection line 10 can be shortened, but also the stress acting on the wiring connection portion due to the operation of the operation panel 9 being retracted. When the operation panel 9 is in a protruding state, the first and second arms 6 supporting the operation panel 9 are provided.
Since the angle 8 is inclined forward, the operation panel 9 does not move to the storage position side or rattle due to the pressing force of the push button on the operation panel 9.

[0014]

As described above, according to the present invention, it is possible to reduce the amount of movement of the connection portion of the lead wire for electrically connecting the switch contact of the operation panel and the circuit of the main body, and the same portion is disconnected. The risk of occurrence is reduced. In addition, by setting the angle of the link, the component force in the direction in which the operation panel is immersed can be prevented from acting at the time of operation, so that it is possible to prevent the occurrence of play without providing a special locking means or the like. In addition, since the operation surface of the operation panel can be configured not to move significantly up and down, it is possible to prevent the occurrence of a gap that allows the inside of the housing to be seen when the operation panel moves in and out.
