Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to an operating lever device, which is applied to, for example, a tape recorder, in which a plurality of operating levers are rotatably supported on a single shaft.

In a tape recorder, a plurality of operating levers are pivotally supported on a single shaft, and operations such as recording and playback are performed by selectively rotating the operating levers.

In this way, when assembling a control lever device in which multiple control levers are pivotally supported on one shaft, first pass the shaft through the required number of control levers, and then attach both ends of the shaft to appropriate fixing members. Fix it.

Therefore, when some of the operating levers are to be replaced due to damage or the like, the shaft must first be removed from the fixed member and then the operating levers must be replaced.

Therefore, the conventional operation lever device of this type is difficult to assemble and disassemble, and the work requires a lot of time.

This invention eliminates these conventional drawbacks, allows assembly and disassembly to be performed easily in a short time, and makes it easy to replace some operating levers without leaving any residue or other effects. The object of the present invention is to provide an operating lever device that can perform the following operations.

An embodiment of this invention will be described below with reference to the drawings.

FIG. 1 shows a board for a 1/ri tape recorder. On the surface of this board 1, a reel shaft, a capstan shaft, a head panel, etc. (not shown) are mounted.

The board 1 is arranged vertically, and an interlocking plate 2 is provided on the back side of the board 1 from its lower end so as to be vertically movable.
Both ends of ... are protruding.

Each interlocking plate 2 has a square hole 3 in a portion protruding from the lower end of the substrate 1.

Each interlocking plate 2 is biased downward by a spring (not shown), and performs recording, playback, and other window operations when moving upward.

A support plate 4 is disposed below the substrate 1.

This support plate 4 has both ends bent upward, and the respective bent portions 5 are attached to the lower end portions of both side surfaces of the substrate 1 by screws or the like.

A single pivot shaft 6 is bridged between the ends of the folded bent portion 5.5 extending toward the front of the substrate 1.

Further, on this shaft 6, operating levers 7 corresponding to the respective interlocking plates 2 are pivotally supported in close proximity to each other.

Each of the operating levers 7 has a through hole 8 between the left and right sides in the middle portion thereof, through which the pivot shaft 6 is inserted, and the through hole 8 is opened at the lower side.

Although the width of this opening 9 is slightly smaller than the diameter of the pivot shaft 6, it can be attached to and removed from the pivot shaft 6 through the opening 9 by utilizing the elastic force of the operating lever itself. It looks like this.

One end of each of the operating levers 7... is connected to each of the interlocking plates 2,
It is inserted into the square hole 3 of...

The support plate 4 has both side edges of its intermediate portion bent upward, and one of the bent portions 10 supports the intermediate portion of the pivot shaft 6 from below.

Therefore, when the other end of the operating lever 7 is now pressed downward, the operating lever 7 rotates about the pivot shaft 6 and pushes the interlocking plate 2 upward with one end thereof.

Therefore, by appropriately selecting and pressing these operating levers 7, recording, playback, and other desired operations can be performed.

Further, according to this embodiment, the operating lever 7 has a through hole 8 opened on the lower side through which the pivot shaft 6 is inserted, and can be attached to and detached from the pivot shaft 6 through the opening 9, so that when assembling,
1. After attaching the pivot shaft 6 to the support plate 4, each operating lever 7
Insert one end into the square hole 3 of the interlocking plate 2, and then insert it into the opening 9.
When the is positioned on the pivot shaft 6 and pushed down, the pivot shaft 6 passes through the opening 9 and fits into the through hole 8, and the operating lever 7 is attached to the pivot shaft 6.

Furthermore, when removing the operating lever 7 from the pivot shaft 6, the operation can be performed in the opposite manner.

Therefore, this operating lever device can be easily assembled and disassembled in a short time, and the operating lever of the unit can be replaced easily.
This can be done quickly without affecting anything else.

Further, the pressing force on each operating lever 7 acts as a bending force on the pivot shaft 6, but since the pivot shaft 6 is supported at its intermediate portion from below by the bent portion 10 of the support plate 4. In addition, it has a strong reaction force against the bending force, and has an excellent effect on strength.

As described in detail above, according to this invention, in an operating lever device in which a plurality of operating levers are rotatably supported on one shaft, the through hole of each operating lever through which the shaft is inserted is placed on the side. By opening it toward the side and allowing it to be attached to and detached from the shaft through the opening, assembly and disassembly can be easily performed in a short time, and some operations can be performed without affecting anything else. Many excellent effects can be obtained, such as the ability to easily replace the lever.
