There are devices that detect the displayed time by sliding the contact piece. According to this, a common electrode is required in addition to the pattern electrode, and if the contact pieces that slide on this common electrode are included, a total of five contact pieces are required.

していく。Therefore, the present invention provides a time detection device that is simple in construction and highly reliable, requiring only one contact.An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, contacts 2 and 2 are formed on a substrate 1 at positions 1 and 12 o'clock on the same circumference, and printed resistors 5 and 6 are formed between each contact. The center of this board 1 is moved by an hour hand pipe 4 which is a moving device.
is passed through, and the contact piece 5 is fixed to this. Therefore, the contact piece 5 rotates in conjunction with the rotation of the hour hand (not shown), and when the hour hand indicates 1 to 12 o'clock, the tip of the contact piece 5 is the contact point 2 - at the 1 to 12 o'clock position. It collides with 2. The contacts at the 12 o'clock and 1 o'clock positions are connected to the (+) and (-) sides of the power supply, respectively, so as the hour hand sequentially displays 1 to 12 o'clock, the voltage generated from the contact piece 5 changes in stages. will continue to increase.
この電圧を検出することによりて時針の表示位置を検出
するものである。By detecting this voltage, the display position of the hour hand is detected.

、16はアリツブフロップ回路である。FIG. 2 shows an example of this detection circuit. In the figure, 6 is an hour detection switch, 7 is a clock pulse generation circuit, and 8 is a code signal generation circuit, which sequentially generates a binary code signal of 12 to 1 every time a clock pulse is supplied. 9 is a D/A conversion circuit that converts the above code signal into a voltage, which is approximately equal to (slightly lower than) the voltage from contact piece 5 when the hour hand displays 1 to 12 o'clock for code signals 1 to 12, respectively. It is set to generate a voltage. Reference numeral 10 denotes a comparator circuit, the (+) input of which is supplied with the voltage from the contact piece 5. 11 is a latch circuit, 12 is a time signal circuit, and 16 is an arrest flop circuit.
以上の構成において、接片5は正時の所定時間前から接

ックパルス発生回路7からクロックパルスが発生する。In the above configuration, the contact piece 5 is in elastic contact with the contact point 2 for a predetermined time before the hour. When the hour comes, switch 6 in Figure 2 is turned on.
is closed, the flip-flop circuit 13 is reset, and the clock pulse generation circuit 7 generates a clock pulse.
このクロックパルスによってコード信号発生回路8から
順次12〜1のコード信号が生じ、これがD / A変
換回路9で電圧に変換されて比較回路10に供給される
。This clock pulse sequentially generates 12 to 1 code signals from the code signal generation circuit 8, which are converted into voltage by the D/A conversion circuit 9 and supplied to the comparison circuit 10.
いま、例えば2時であったとすると、接片5には、電源
電圧をEボルトとしたとき、/1.ボルトの電圧が生じ
比較回路10の(+)入力に供給されている。For example, if it is 2 o'clock, the contact piece 5 will have /1.0 when the power supply voltage is E volts. A voltage of volts is generated and applied to the (+) input of comparator circuit 10.

/11-I L(9s-e)...(6 is a minute voltage) voltage is generated, and the voltage when code signal 2 is (''/, 1-1)K
Therefore, an output is generated from the comparator circuit 10. As a result, the flip-flop circuit 13 is set, the clock pulse is stopped, and the code signal 2 is latched into the latch circuit 11. The output of the latch circuit 11 generates a time signal twice, thereby announcing the time of 2 o'clock.
以上のようにして各正時において報時が行なわれる。As described above, time reporting is carried out at each hour on the hour.

確な比較を行なうことができる。Note: By using a common power supply for the A converter circuit 9 and the power supplies at both ends of the resistors 6 to 3, accurate comparisons can always be made in the comparator circuit 10 without being affected by fluctuations in the power supply voltage. can.
また上記の実施例では基板1を固定して接片5を回転さ
せたが、逆に接片5を固定して基!1を時針に連動して
回転するようにしてもよい。Further, in the above embodiment, the base plate 1 is fixed and the contact piece 5 is rotated, but in contrast, the base plate 1 is fixed and the contact piece 5 is rotated. 1 may be rotated in conjunction with the hour hand.
なお万一接片が接触不良を起こした場合には、比較回路
10の(+)入力に入力電圧が供給されなくなるため比
較回路10から出力が発生せず報時が行なわれなくなる
。したがって従来のように間違った時刻が報時されるこ
とがなく、シかも直ちに異常に気が付くものである。In the event that a contact failure occurs in the contact piece, no input voltage is supplied to the (+) input of the comparator circuit 10, so that no output is generated from the comparator circuit 10 and no time notification is performed. Therefore, an incorrect time is not reported as in the conventional case, and abnormalities can be noticed immediately.
以上のように本発明によれば、一つの接片で時刻を検出
することができ、信頼性が向上するとともに構成が簡単
で組立が容易になる。As described above, according to the present invention, time can be detected with one contact piece, reliability is improved, and the structure is simple and assembly is easy.
