Description

[Detailed explanation of the idea] The present invention relates to a watch.

In conventional portable digital watches, the outer edge of the front cover that covers the time display window is fixed by a cover frame that fits into the window hole, but the back of this cover frame is held by, for example, a support plate. has been done.

However, since the cover frame and the support plate are separate members, it takes time and effort to manufacture and assemble the watch, and the watch becomes thicker by the thickness of the support plate, so there is a certain limit to how thin the watch can be made.

The present invention eliminates the above-mentioned drawbacks, and an embodiment thereof will be described below with reference to the drawings.

In Figs. 1 and 2, reference numeral 1 denotes a watch case for a portable digital watch, and this case is A type consisting of a front case 1a and a rear case 1b.

A rectangular window hole 2 for displaying the time is formed in the front case 1a.

A front cover 3 made of a transparent plate is disposed to cover the window hole 2.

The outer peripheral edge of the front cover 3 is bordered with steps, and this outer peripheral edge is clamped and fixed between a front cover presser 4a of a support 4 provided inside the watch case 1 and a display panel 5.

That is, as shown in FIGS. 2 and 3, the support body 4 is, for example, press-molded from a thin metal plate and has a U-shaped side surface, and has a rectangular hole 4b bored in the center.

A front cover presser 4a is formed on the front surface of the support body 4 and protrudes forward along the periphery of the hole 4b.
The edge of the front cover presser is formed in a layered manner so as to be inclined toward the inside of the hole.

The front cover presser 4a fits into the window hole 2 and is exposed at the front of the watch case 1, and its edge presses the outer peripheral edge of the front cover 3.

The support 4 holds therein a display panel 5 disposed on the back of the front cover 3.

The display panel 5 displays the time, and its front outer periphery holds the edge of the front cover 3 together with the front cover presser 4a.

Note that 6 is a polarizing plate and 7 is a reflecting plate.

Further, the support body 4 is provided with a plurality of (four in the drawings) leg pieces 4C projecting in one direction toward the back.

Each leg piece 4C... passes through a support hole 8a... provided transparently in the circuit board 8, and has a twisted portion 4d as an example of a fixing portion at the protruding end. Due to...
The support 4 is fixed to this circuit board.

The circuit board 8 is located on the back side of the display panel 5, and the display panel is electrically connected to the circuit board through lead rubber 9.

10 is a crown for adjusting the time, and 11 is a sound emitting groove for a buzzer sound.

To explain the assembly, first place the support 4 with the front cover presser 4a facing down on a suitable workbench, then insert the front cover 3 into the support and fit the front cover into the support hole 4b. let

Then, the display panel 5 is placed in the support body 4, stacked on the front cover 3, the lead rubber 9 is placed at a predetermined position, and the circuit board 8 is placed on top of it.

At this time, the leg piece 4C of the support body 4 is inserted into the support hole 8a...
, twist the ends of each leg piece with an appropriate tool, and fix the support body 4 to the circuit board 8 through the twisted portions 4d. It is supported by the panel 5, and at the same time, the display panel is also held in a conductive state with the circuit board 8.

With the front cover 3, support 4, display panel 5, and circuit board 8 formed into blocks in this manner, fit the front cover holder 4a into the window hole 2 of the front case 1a, and cover the rear case 1b from the back. Bye.

It goes without saying that the clock according to the present invention can also be used as a clock in a broader sense, such as a stopwatch or a timer.

As explained above, according to the present invention, since the front cover presser constitutes a part of the support body, manufacturing and assembly are easy, and the structure is also simple, and the thinness of the watch is a distant relative. can.

In addition, since the display panel etc. can be made into blocks and then incorporated into the watch case, assembly is easy and
You can check the operation of the display panel before assembly.
