Is taken out as a voltage, and the built-in A / D converter outputs the X-axis coordinate and the Y-axis coordinate as digital values.

The X-axis coordinates and the Y-axis coordinates output from the touch panel drive section 31 are stored in a coordinate storage section 32. The coordinate storage unit 32 stores coordinates input to the transparent touch panel 3.
The latest position information is stored with the movement of the coordinates, but when the position information is no longer input from the transparent touch panel 3, the value is cleared. The coordinate output from the coordinate storage unit 32 is supplied to a distance calculation unit 33 and an angle calculation unit 34.

The distance calculating section 33 calculates a linear distance between the coordinates at which the axis of the clock is displayed and the coordinates output from the coordinate storing section 34. The calculated distance is calculated by the distance determining section 35. It is compared with the length of the short hand stored in advance, and when the length of the short hand is longer than the length between the input coordinates and the axis, a signal 0 is output assuming that the short hand is selected, and the input coordinates and the distance between the axes are output. When the length of the short hand is shorter than the length of the long hand, the signal 1 is output assuming that the long hand has been selected.

Luo angle and calculates a, the upward direction of the coordinate axis of the watch is displayed (0 o'clock direction) is 0 degrees, as the 90-degree right direction (3 o'clock), calculated 360 degrees.

The angle judging section 36 compares and judges the angles indicated by the short hand and the long hand from the short hand angle calculating section 24 and the long hand angle calculating section 25 with the angle from the angle calculating section 34.
Position close to have not Re needle is determined whether the instructed. At this time, each of the needle when the position apart when or from each of the needles 10 degrees or more is close to within 5 ° is indicated is treated as not also instructed not Re needles are.

The angle judging section 36 also has a distance calculating section 33.
Similarly, when the vicinity of the short hand is indicated, the signal 0 is output assuming that the short hand is selected, and when the vicinity of the long hand is indicated, the signal 1 is output as the long hand is selected.
Moreover, a high impedance is outputted when not also be selected without Re needles are.

The distance judging section 35 and the angle judging section 36
Is input to the specifying unit 37. In this specifying unit 37, when none of the hands is selected by the angle determination unit 36, the output of the distance determination unit 35 is referred to. The needle selected as described above is specified.

Identifying section 37 for clarifying the identified needle
AND the 0.5 second signal of the clock unit 21 to the selected output of the short hand angle calculation unit 24 and the long hand angle calculation unit 25
Then the selected hand blinks. If the hand specified by the specifying unit 37 is a short hand, a signal 0 is output from the specifying unit 37 to the time adjustment unit 38 if the specified hand is a long hand.

In the time adjusting section 38, the specifying section 37
Calculates the time from the coordinates of the movement of the needle specified by the coordinate based on the coordinate value output from the coordinate storage unit 32,
A predetermined position in the clock unit 22 or the alarm setting time storage unit 23 specified in advance by a switch, that is, the hour position is adjusted when the short hand is selected, and the minute position is adjusted when the long hand is selected. Will be.

For the time adjustment, there is a method of calculating the time from the angle. In order to increase the response speed, the time adjustment unit 3
8 is provided with a table comparing the angle and the time, and by referring to this table, it is possible to carry out promptly.

Further, when the long hand is specified by the specifying unit 37, it is determined that the adjustment has been completed due to the absence of the coordinate designation from the transparent touch panel 3 and the second counter of the clock unit 22 selected by the real time setting key 4 For
Is assigned the time adjuster 38 yo than zero, the counter value of the clock unit 22 is cleared the seconds counter a moment the time set by the operation in a corner of the analog clock display by one-pulse generating circuit (not shown) digital By displaying, the set time can be clarified.

FIGS. 4 and 5 are operation flowcharts of the analog display clock of the present apparatus, and FIG. 6 is a view showing a display and a screen for explaining the actual clock setting of the analog display clock of the present apparatus. 6, X indicates the counter value of the clock unit 22, Y indicates the angle value calculated by the long hand angle calculation unit 22, and Z indicates the angle calculated by the short hand angle calculation unit 24.

The processing shown in FIGS. 4 and 5 is as follows. In step S1 (hereinafter, step will be abbreviated, and expressed by S and a number), it is determined whether the setting of the real time has been selected by the key switch, and in S2, it is determined whether the setting of the alarm time has been selected. If it is determined in S1 that the real time has been selected, 0 is substituted for the variable A in S3, and if it is determined in S2 that the alarm time has been selected, 1 is substituted for the variable A in S4. In FIG. 6A, it is assumed that the real time is selected and 0 is substituted for the variable A. Next, in S5, the process waits for coordinate input on the transparent touch panel 3. If it is confirmed in S5 that the input of the coordinates on the transparent touch panel 3 has been performed, then in S6, the angle with respect to the axis coordinates is calculated from the input coordinate position.

In S7, the distance between the input coordinates and the axis coordinates is calculated. In S8, S is set based on the variable A.
The angles from the axes of the short hand and the long hand selected in S1 and S2 are held.

In S9, it is determined whether or not the angles of the short hand and the long hand held in S8 from the axis have a difference of 15 degrees or more. This is because it is difficult to determine the selection of the needle based on the angle when the short hand and the long hand are approaching each other.
In S10, processing for switching to needle selection based on the distance from the axis is performed. As shown in FIG. 6B, when the short hand (1 degree) and the long hand (12 degrees) are close to each other, for example, within 15 degrees, the hand is switched to the needle selection based on the distance.

If it is determined in step S9 that the short hand and the long hand are separated by 5 degrees or more, then in step S11, it is determined whether the angle calculated in step S6 is within 10 degrees of the short hand angle.
However, similarly, it is determined whether it is within 10 degrees of the long hand.

When selecting a long hand as shown in FIG. 6 (a), if an instruction within 10 degrees from the hand is designated as at point A, coordinate input is used as the choice of the needle. When it is more than 10 degrees away from the needle, the coordinate input is ignored.

If it is determined in S11 that it is within 10 degrees of the short hand, 0 is substituted into a variable B indicating that the short hand has been selected in S13, and it is determined in S12 that it is within 10 degrees of the long hand. If so, in S14, 1 is substituted for a variable B indicating that the long hand has been selected. If it is determined in S11 and S12 that the hands are separated from the respective hands by 10 degrees or more, the coordinate input is invalidated.

In S10, the distance of the short hand stored in advance is compared with the distance calculated in S7. This is Figure 6
As shown by the dashed line in (b), when an input is made within coordinates whose radius is the length of the short hand, the short hand is processed as if the long hand was selected.

If it is determined in S10 that the short hand is shorter than the short hand distance, a variable B indicating that the short hand has been selected is used in S15.
Is substituted into the variable B, and if it is determined that it is longer than the short hand distance, in S16, 1 is set to a variable B indicating that the long hand has been selected.
Is substituted. In S17, a 0.5 second signal for blinking the hand selected by the variable B is transmitted, and the blinking of the hand is instructed. In S18, the coordinates instructed on the transparent touch panel 3 are converted into an angle from the reading axis.

In step S19, the angle is converted to time in the coordinate-time conversion table stored in advance for the needle stored as the variable B. For example, when the long hand is selected by the variable B, the angle 90 degrees is converted into 15 minutes, and 180 degrees is converted into 30 minutes, and the clock unit that measures the actual time selected by the variable A, the alarm time storage. It is set to the unit of the selected needle by have not Re of variables B of part.

In S20, it is determined whether or not the transparent touch panel 3 is instructed, and the end of the setting is detected. In S21, the variable A determines whether the setting target is real time or an alarm.
To judge.

In S22, it is determined from the variable B whether the long hand has been selected. If the long hand has been selected, S
At 23, the second is cleared by substituting 0 into the second counter of the clock unit 22, and at S24, the contents of the clock unit 22 or the alarm set time storage unit 23 selected by the variable A at the lower right of the liquid crystal display unit 2. Is digitally displayed.

In FIG. 6C, the display time 1 shown in FIG.
This shows an operation for changing the time from 1:20 to 11:40. Point A in FIG. 6A is designated, and the long hand is selected. The display of the long hand changes from lighting to blinking according to the selection.

Next, the coordinate is moved by the coordinate instruction until the time when the instruction is set (40 minutes in this example), the time is calculated from the coordinate angle (240 degrees) of the point where the instruction input is lost, and this time is set. The second of the time is set to 0 second, and the time is displayed on the digital display near the analog clock for a specific time.
