Abstract

PURPOSE:To obtain a timepiece convenient for a user while dealing with versatility of its use by optionally changing the direction of time display as the user likes with an external switch. CONSTITUTION:A display switching circuit part B is composed of a switching circuit 103 which indicates what position and what direction the contents of a time counter 12 are to be displayed at and in according to the contents of a quad counter 102 operated by a signal from an external switch 101. For example, when the contents of the counter 102 are (0.0), display is obtained as shown in the figure, and when (0.1), (infinity .01) is obtained; when (1.1), display shown in the figure B is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a digital display type electronic timepiece KIjl which allows the user to read and read the normal time in any direction desired by the user using an external switch.

Conventional electronic watches with digital displays often read the time by wearing them on the wrist or straddling them on a desk, so the viewing direction is almost constant. Therefore, it was only necessary to read the -koku from a certain direction. However, the way watches are used has diversified,
Pendants and accessories.

It is often incorporated into lighters and ballpoint pens,
The direction in which it is carried and the direction in which it is viewed are not the same, and for some users, the inner hand that shows the time does not match the bullet that the user wants to see, making it inconvenient to read the time. When looking at a watch in a box, the viewing direction will vary depending on whether you just lift it up or turn it upside down, but when you watch it vertically, you are not forced to always look at it in one direction. Ta. Also, if you look at it from a desk, etc., you are inevitably forced to put the book down.

The present invention aims to improve the above-mentioned drawbacks, and aims to improve the above-mentioned drawbacks.
1. The user can now use the bullet that displays the time in any direction they desire, responding to the diversification of how watches are used.1. #Digital f that is convenient for users! This makes the yvce electronic clock capable of TIF.

The present invention will be described below based on an embodiment shown in the accompanying drawings.

In the present invention, the display switching circuit section B and 1 switch the display section A emitted from the display element for displaying numbers and the position and direction of the # hour displayed on the display section AK by an external switch 101K.
It is composed of a display drive circuit section C that drives and displays the display section M, and a time counter circuit section P that counts time.

To explain from the display section A, this display section consists of A number of display substrates 1. On the display substrate 1, there are 4 dot display elements 2 that display numbers in four directions (up, down, left and right).
Colon display elements 3 are arranged to separate digits and hours, and these colon display elements 2 display the contents of the time counter 12 of the % time counting circuit in the display switching circuit. It will be displayed in the position and direction of B's instructed S stutter. In addition, in the current display section Ar, the contents of the time counter 12, 101108 minutes, are displayed upward in the left and right array. Each number digit is made up of 6 x 6 dots.

Next, the 1-display switching circuit section B will be explained.

This display switching circuit section B includes an external switch 101, and a quaternary counter I that operates according to a signal from the external switch 101.
Depending on Q2 and the contents of the quaternary counter, the time
It is comprised of a switching circuit 1032 that instructs where on the display section A the contents of ``are displayed'' and in the interior of the . Here, when the display on the quaternary counter 102 is shown,
If the contents of the quaternary counter 102 are ro-oJ, the display will be as shown in Figure 1, and if it is ro or IJ, the display will be the second one.
At the bottom of the figure, 〈〈〈〈〈〉〈〉〉〉〉〉〈rgo:OIJ〉, as shown in Figure 4, in ``1・rB'', as shown in Figure 4, ``1・rB'' ” Tonal.

Next, the display drive circuit section OK will be explained. This display drive circuit section C includes a dot pattern generation circuit 110 & a dot display element 2 to display the content of the time counter 12, which is instructed by the switching circuit 103K as to the display location and direction. The latch driver circuit 111 drives the element 2 for display.

Next, the hour meter #Ij circuit section DK will be explained.

This time counting circuit includes an oscillation circuit 10 that oscillates a reference signal, a frequency dividing circuit 11 that converts the signal into an IHz second signal (5+), and converts the second signal into a normal time! ! 1I7ic, and a time counter 12 counting for 1I7ic.

The signal output from the time counter 12 is then input to the switching circuit 103.

Next, the operation of the circuit according to the present invention having the above-described configuration will be described in the case where the time is displayed rotated by 180 degrees using an external switch.

First of all, the current watch display has one row on the left and right, with one on the upward hand.
0BS08 minutes is displayed. At this time, the contents of the quaternary counter 102 are "0.0". Now, when the external switch 101 is switched twice, the contents of the quaternary counter 102 are "1.0", and the switching circuit 103 changes the position to be displayed first in response to the signal of the 1 hour counter 12, and the 10 o'clock digit is 1. Indicate the minute digit c and 1m digit to the 10f+ digit, the 10 minute digit to the 1 hour digit, and the 1 minute digit to the 10 o'clock digit, and then instruct the direction of each digit by turning it 180-. L? -As a result, the display section Affr9 (T:Ol) is displayed.2. .

According to the configuration of the present invention, F),
Since the user can arbitrarily select the direction in which the @ time is displayed, it is very easy to set the time, making it possible to create a convenient digital display electronic clock *! It is something to do.
