Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a mounting structure for a switch board.

[Conventional technology]

Conventionally, for various electrical devices, especially instruments that process information using computers, etc., it has been common for a large number of operation switches to be disposed on the surface of the casing, and in addition to these switches, for example, Floppy disk decks, data printout devices, etc. are often arranged in parallel.

By the way, while there is a strong demand for miniaturization of the above-mentioned instruments due to restrictions on installation space, as the functions of the above-mentioned instruments have improved, the number of operation switches has also increased, and the area occupied by these switch boards has become larger. However, there was a problem in that the overall volume of these instruments could not be easily miniaturized.

In order to solve this problem, proposals have been made in which the switch board is housed in a casing so that it can be retracted from the casing, or it can be folded onto the surface of the instrument, thereby reducing the size of the switch board (for example, the 167628, 60-62138, etc.).

[Problems with conventional technology]

However, in the structure in which the switch board is stored or folded in the instrument body, the means for fixing the switch board in the stored or drawn out state are different structures, or the switch board does not have any fixing means in the drawn out state. In most cases, the posture of the board in the storage drawer state or intermediate position cannot be reliably controlled, resulting in a drawback that operation and handling become troublesome.

[Problems solved by invention]

In view of the above-mentioned problems, this idea was developed to make it possible to easily downsize the casing as a whole even if there are a large number of operation switches, and to create a switch board that is easy to operate, as it can be fixed in the storage drawer state or moved between them. This was done for the purpose of obtaining a mounting structure.

[Technology to solve problems]

That is, in the mounting structure of the switch board of this invention, one end 3A of the base plate 3 on which various switches 2 are disposed is slidably fitted into the slide groove 4 provided in the casing 1 so as to be freely rotatable about the sliding portion 5 as the rotation axis. A link 7 is connected between the surface 3B of the substrate 3 parallel to the sliding direction and the casing 1 via pivot points 6, 6, and the substrate 3 is connected to the upper end of the slide groove 4. A locking pawl 8 that releasably engages with the base plate 3 at a position corresponding to the lower end is pivotally supported on the casing 1.

〔Example〕

This invention will be explained below using examples.

The drawings are a sectional view taken along the line -- in FIG. 1, FIG. 3 is a sectional view in the expanded state, and FIG. 4 is a front view of the main parts of the embodiment in the expanded state.

The switch board mounting structure 1 of this invention is arranged, for example, on the front surface of the casing 1, and one end 3A of the board 3 on which various switches 2...2 are arranged slides into the slide groove 4 provided in the casing 1. 5 is the rotation axis (Fig. 2, 3).
(see figure), pivot points 6, 6 between the surface 3B parallel to the sliding direction (arrow X) of the substrate 3 and the casing 1.
The link 7 is connected to the casing through the link 7, and a locking pawl 8 that releasably engages the board 3 at a position where the board 3 corresponds to the upper and lower ends of the slide groove 4 is pivotally supported on the casing. ing.

In the above embodiment, only various switches 2...2 are provided on the board 3, and electronic circuits, etc. (not shown) operated or driven by these switches are provided inside the casing 1A, and a flexible cable is connected between them. Alternatively, the connection may be made by a cableless method using ultrasonic waves or optical signals.

In FIGS. 3 and 4, 2A indicates a signal transmitter in the case of a cableless method, and 2B indicates a receiver provided in the casing 1A.

Furthermore, the casing 1A at the back of the board 3 can be provided with a floppy disk deck 2C, a printout device 2D, etc., as shown in FIG.

[Function] In this invention, in the normal state, the substrate 3 is connected to the casing 1A as shown in FIG. 1 or 2.
It is supported upright so as to be flush with the front surface, and is fixed by a locking pawl 8 that engages with the back surface of the circuit board 3 of the switch board.

If necessary, the locking pawl 8 is rotated by an appropriate means to separate it from the back surface of the substrate 3, and the substrate 3 is slid along the slide groove 4 as shown in FIG. At this time, together with the restraint by the link 7, the board 3 protrudes toward the front of the casing 1 with the switch 2 side facing upward, as shown by arrow M, and in the fully protruding state, it is locked in the locking part at the upper end of the board 3. The claws 8 are fitted to fix the substrate 3 again.

Since the board 3 and the inside of the casing 1 are electrically connected as described above, it is possible to operate the switch in this state.

Further, at this time, other devices 2C and 2D located on the back side of the board 3 are exposed, and these instruments can also be used.

When it is not necessary, the locking pawl 8 is rotated again using an appropriate means to release the fitting, and the board 3 is slid along the slide groove 4 and raised to its original state.

When the substrate 3 moves upward along the slide groove 4, it is hooked and fixed again by the locking claw 8 at its lower end.

〔effect〕

As explained above, this idea allows electronic devices with various functions to be moved in a sliding manner, making them foldable, so they can be used three-dimensionally. It is now possible to stack devices on top of each other, allowing devices to be significantly downsized without compromising functionality.
The vertical movement of the switch board is restrained by links, so it can be moved reliably, and it is locked and fixed by the same locking pawl 8 at each position at the top and bottom ends, so it has a simple structure and can be fixed securely. It has various practical effects such as making it possible to
