BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for a push button switch used in an electronic lock device.

[0002]

2. Description of the Related Art Various types of electronic locks are known as locking devices for locking architectural or automotive doors. A push-switch type keyless entry device, which is usually provided with a plurality of switches for inputting a 5-digit numerical value and operates these switches on and off with a finger in a predetermined order, is currently used in passenger cars, transport vehicles, buildings or secret rooms. Widely used as a door lock device. However, the push-switch type keyless entry device is not desirable in terms of theft prevention because a plurality of switches are installed so as to be exposed outside the room. Therefore,
There has been proposed a new electronic lock which unlocks with a predetermined code by turning on / off one switch for generating a Morse code signal.

For example, Japanese Unexamined Patent Publication No. Sho 61-142268 discloses an electric lock unlocking device provided with display means. This unlocking device has one key for inputting a password,
A count means for counting a value proportional to the continuous operation time or the number of times of operation of the key as a password input by the key, a display means for displaying the value counted by the count means, and a key for setting are operated. Then, the value counted by the counting means is compared with a value set by a password setting means provided separately, and when both match, a predetermined signal is output. And unlocking means for unlocking.

A push button switch of this type of electronic lock device is not known, but is disclosed, for example, in Japanese Patent Application No. 2-150134 already filed by the present applicant. The electronic lock device according to the prior application includes a display means for displaying a symbol, a carry key, a carry key, and a sign displayed on the display means being moved up or down every time the carry key or the carry key is operated. Each time the carry-up key or the carry-down key is simultaneously operated, the symbol displayed on the display means is stored, and one or a combination of the stored symbols is compared with a pre-registered password. And an electric circuit for outputting an unlock signal when the two coincide with each other. Also, the electric circuit has a function of canceling the previously stored symbols and returning to the initial state when the carry-up key and the carry-down key are continuously operated for a longer time than a preset time. doing.

[0005]

By the way, in the conventional electronic lock device, as shown in FIG. 3, the number displayed on the display means 12 is registered by the operator pressing the carry-up key 13 and the carry-down key 14 at the same time. Is what is done. Therefore, the carry key 13 and the carry key 1
Unless 4 is pressed at the same time, the numbers are not registered, causing erroneous registration, and the operability is poor.
Further, since the carry-up key 13, the carry-down key 14, and the display means 12 are provided at different positions in the operation panel 11, a large mounting space is occupied.
Therefore, the mounting place is limited.

This invention provides a mounting structure of a push button switch in an electronic lock device which has good operability and can be mounted in a minimum space regardless of a mounting place.

[0007]

The push-button switch mounting structure of the electronic lock device according to the present invention comprises two push switches for operating the electronic lock, which are placed on the printed circuit board at an interval, and two push switches. Symbol display means mounted between the switches, two integrally formed transparent cover mounted on the push switch and the symbol display means, having a through hole of a size substantially along the outer periphery of the transparent cover, A transparent cover is arranged in the through hole, and the switch case houses a printed circuit board, a pressing switch, and a display means, and a rubber packing is fixed to a gap between the through hole of the switch case and the outer periphery of the transparent cover. Pressing the center of the transparent cover turns on two pressing switches simultaneously, and pressing the end of the transparent cover turns on one of the two pressing switches.

[0008]

The sign display means is arranged between the two push switches for operating the electronic lock and the transparent cover integrally formed thereon is mounted thereon, thereby improving the operability of the electronic lock device.
Reduce the mounting space.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

In the embodiment of the present invention, as shown in FIG. 1, symbol display means 7 is provided on the printed circuit board 4, and push switches 5 and 6 are provided on both sides of the display means 7. Usually, the symbol display means 7 is a segment diode for displaying numbers, and the push switches 5 and 6 are micro switches. A transparent cover base 2 is placed on the push switches 5 and 6 and the symbol display means 7, and a transparent cover having a convex portion 1a is provided on the cover base 2. The transparent cover base 2 and the transparent cover 1 are integrally formed of, for example, an acrylic resin, and the concave portions 1b and 1c of the transparent cover 1 are formed.
Is painted or the like. As shown in FIG. 2, the switch case 3 has a through hole 3 having a size substantially along the outer periphery of the transparent cover 1.
a, and the transparent cover 1 is disposed in the through hole 3a. As shown in FIG. 1, a printed circuit board 4, push switches 5 and 6, and symbol display means 7 are accommodated in the switch case 3. An annular rubber packing 8 is provided between the through hole 3 a of the switch case 3 and the outer periphery of the transparent cover 1. The transparent cover 1 and the transparent cover base 2 hold the inner diameter side 8a of the rubber packing 8, and the switch cover 3 and the annular rubber packing holder 9 hold the outer diameter side 8b of the rubber packing 8.

Since the projection 1d of the transparent cover 1 and the projection 3b of the switch cover 3 are pressed against the rubber packing 8, water is prevented from entering the push switches 5, 6 and the symbol display means 7. .

In the above configuration, when the concave portion 1b of the transparent cover 1 shown in FIG. 2 is pressed, a part 8d of the rubber packing shown in FIG. The number displayed in the section 1a is counted up. Also, the concave portion 1c of the transparent cover 1
When the is pressed, a part 8c of the rubber packing is bent and the pressing switch 5 is pressed to be turned on, and the number displayed on the convex portion 1a of the transparent cover 1 is counted down. When the convex portion 1a of the transparent cover 1 is further pressed, the parts 8c and 8d of the rubber packing are simultaneously bent, and the pressing switches 5 and 6 are simultaneously pressed and turned on at the same time.
The number displayed on the convex portion 1a is registered.

In the above embodiment, the annular rubber packing 8 provided separately from the outer periphery of the transparent cover 1 and the gap between the through holes 3a of the switch cover 3 is shown as a separate body. To form the rubber packing 8.

[0014]

As described above, in the present invention, the push switches are arranged on both sides of the symbol display means, and the transparent cover integrally formed thereon is placed thereon, so that the central portion of the transparent cover is pressed. Thereby, the two push switches can be pushed simultaneously, and the mounting space for the push button switch of the electronic lock device can be reduced. for that reason,
An erroneous registration due to an erroneous operation does not occur, and an installation place is not limited, and it can be easily installed even in a narrow place.
