Description

  The present invention relates to an indicating instrument mounted on a vehicle represented by, for example, an automobile or a motorcycle, and more particularly to an indicating instrument provided with a detecting means for detecting a base point position of a pointer.

  For example, in an indicator instrument that rotates a pointer using a motor consisting of a stepping motor as a drive source, the actual pointer position indicated by the pointer on the scale plate due to external factors such as vibration and shock, and a drive / control circuit The position of the pointer on the control due to the movement may be shifted (so-called step-out), and normal pointer instruction may not be performed.

  For this reason, a stopper is provided to stop the pointer at a predetermined base point position (for example, the zero point of the indicator plate). For example, when the power is turned on, the pointer is forcibly rotated toward the stopper, and the pointer is stopped by the stopper. It is known to perform an initialization process that matches the actual pointer position with the control base point position at the position (that is, the base point position). However, according to this process, the drive signal is supplied unconditionally regardless of the position of the pointer at startup, so the pointer may vibrate little by little on the stopper or abnormal noise may occur. There were difficulties in terms of visibility and merchantability.

In order to avoid such an inconvenience, for example, as described in Patent Document 1 below, there is known a technique in which an induced voltage generated in a coil of a stepping motor is monitored and a pointer stop by a stopper is detected based on the induced voltage. ing. However, the detection of the pointer stop based on the induced voltage has a complicated and expensive circuit configuration for detecting the induced voltage, and it is difficult to detect the pointer stop when the induced voltage is weak. there were.
JP 2001-327192 A

On the other hand, it is also known to detect a pointer stop using a dedicated detection means including a switch instead of an induced voltage. For example, in Patent Document 2 below, a pointer stop is detected using a pair of contact members, The operation of the stepping motor is stopped after performing a predetermined process. According to such a technique described in the literature, a dedicated detection means is required, but there is an advantage that a pointer stop can be detected accurately with a small number of parts and the load on the circuit can be reduced.
JP 2001-264123 A

  However, the indicator instrument described in Patent Document 2 is arranged so that the pointer stops when the pointer rotates counterclockwise (decrease indicating direction lower limit position) by disposing the detecting means near the minimum indicating position (zero position) of the pointer. In order to detect the pointer stop (pointer stop at the upper limit position of the increase instruction direction) when the pointer rotates in the reverse direction (clockwise) It is necessary to arrange another detection means (contact member). For this reason, there is a problem that the number of parts increases when the detection means is shared by the indicating instruments having different increasing / decreasing directions.

In FIG. 4, the combination meter M is connected to a control means 220 including a microcomputer 200 and a drive circuit 210. The microcomputer 200 receives an input signal from an in-vehicle sensor (not shown) (specifically, a speed signal from the speed sensor, a remaining fuel signal from the fuel sensor, a temperature signal from the water temperature sensor) through each input terminal 230, These are arithmetically processed according to a predetermined program, and a control signal for operating the hands 1 to 3 is output to the drive circuit 210 according to the input signal at that time.

By having the first and second fixed contacts 142b and 142c corresponding to the above, it becomes possible to share the detection means with the minimum necessary component configuration (two parts of the first and second contact members 141 and 142). Cost reduction can be achieved.

  Moreover, in this embodiment, since the 1st contact member 141 and the 2nd contact member 142 consist of metal board | plate materials (thin board), a process is prepared and it can achieve improvement in manufacturing and cost reduction.

  Further, in the present embodiment, a fixed side stopper portion 132 is interposed between the first movable contact 141d and the second movable contact e, and the first side between the fixed side stopper portion 132 and the movable side stopper portion 131 is the first. By pressing the movable contact 141d and the second movable contact 141e, the hands 1 to 3 can be stopped at a certain position.
