Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to display devices such as fluorescent display tube meters used in audio equipment such as cassette decks, and in particular to a mounting device for filters used for display purposes, and is directed to a reduction in the number of parts and installation work. This is intended to simplify the process.

Conventionally, this type of mounting device has generally been
As shown in FIGS. 2 and 2, a meter 1 made of a fluorescent display tube is held between a plurality of protruding pieces 2a and pressing pieces 2b integrally formed with a meter holder 2, and an elastic tongue piece 2c of the meter holder 2 is held. By engaging the engaging portion 3b through the through hole 3a formed in the housing 3, the meter receiver 2 is pressed forward by the protruding piece 3c formed integrally with the housing 3, and the elastic tongue piece is pressed forward. 2c
is pressed into contact with the engaging portion 3b, so that the meter 1 can be attached to the housing 3.

On the other hand, a filter 5 made of an elastic transparent thin plate and suitably colored is disposed on the front surface of the display section of the meter 1, and the filter 5 is disposed on the rear surface of the meter decoration 4. Projecting pieces 5a and 5b are formed integrally with a plurality of notched engagement pieces 4a and 4b.
Note that 7 is a transparent window attached to the front panel 6.

In this way, in conventional devices, the meter 1 is mounted directly using the casing 3, so there are restrictions on the placement and dimensions of the casing 3, and the number of parts required for installation is large, making the installation work complicated. It had the disadvantage of being.

The present invention is intended to improve the above-mentioned conventional drawbacks, and one embodiment of the present invention will be described below with reference to FIGS. 3 to 5.

Reference numeral 8 designates a front panel which also serves as a mounting board, and has a notch 8a formed at its upper end, and an engaging portion 8b protruding inwardly formed at its lower end. Further, a decorative plate 9 is attached to the front surface of the front panel 8. Reference numeral 10 denotes a transparent window that is fitted and fixed to the window 8c of the front panel 8, and a mounting member 11 is provided on the back side of the transparent window. The mounting member 11 is made of synthetic resin or the like, and is integrally formed with a protruding piece 11a at the upper end and an elastic piece 11b bent into a U-shape at the lower end. The mounting member 11 has a protruding piece 11a.
is inserted into the notch 8a of the front panel 8, and the elastic piece 11b is attached by being engaged with the engaging portion 8b. Further, a pair of opposing pieces 11c are integrally formed on the left and right rear surfaces of the mounting member 11,
The facing piece 11c has an abutting piece 11d on the upper side and an L-shaped position regulating piece 11e on the lower side.
are formed, and further each facing piece 11
A pressing piece 11f having key-like elasticity and protruding rearward from the opposing piece 11c is integrally formed in the central part of c. Further, on the upper rear surface of the mounting member 11, there is provided a pressing piece 11 that protrudes rearward and has key-like elasticity.
g is integrally formed.

In addition, a window hole 1 is provided in the center of the mounting member 11.
1h, a locking piece 11i is integrally formed at one end of the rear surface, and an engaging protrusion 11j is integrally formed at the other end.

12 is a display device such as a meter, and a terminal 12a of this display device 12 is connected to a printed wiring board 13 by soldering. The display device 12 is mounted from the rear of the mounting member 11 to the opposing piece 1.
When inserted between the abutting piece 11d and the position regulating piece 11e of 1c, the insertion is between the abutting piece 11d and the position regulating piece 1.
It is regulated by coming into contact with the vertical piece 1e, and its lower end is regulated by being placed on the horizontal piece of the position regulating piece 11e.
Then, it is pressed downward by the pressing piece 11g. Furthermore, it is prevented from coming off by the key-shaped portion of the pressing piece 11f protruding from the opposing piece 11c, and thereby the display device 12 is attached to the rear surface of the attachment member 11.

Reference numeral 14 designates a flexible, light-transmitting filter that is suitably colored and has a notch-shaped locking portion 14a. Further, at the base of a pair of opposing pieces 11c integrally formed on the mounting member 11, there is a notch 1 into which the filter 14 can be inserted, as shown in FIG.
1k is formed. The filter 14 is inserted into the notch 11k from the engaging protrusion 11j side of the mounting member 11, and the end of the filter 14 engages with the locking piece 11i, and the locking portion 14a of the filter 14 is inserted into the engaging protrusion. 11j by pushing the filter in while bending it.
In this case, the center portion of the filter 14 is properly regulated by the upper part of the opposing piece 11c of the mounting member 11, so that the filter 14 can be reliably attached without any lifting or the like occurring in the center portion.

As described above, the present invention is configured such that a filter configured as a part of a display device is inserted and attached from the side into a mounting member attached to a housing such as a front panel. It has a small number of parts and is easy to install, making it very practical.
