摘要： The present invention aims to prevent a nonrotation state from being brought about even when a drive allowance is changed by variations in a stepping motor or the like. A pulse down counter circuit outputs pulse down control signal for subjecting main drive pulse to control pulse down when time is counted for a predetermined time period. When a detecting signal exceeding a reference threshold voltage detected by a rotation detecting circuit is detected at a first detection section at start of a rotation detecting time period, a control circuit resets the pulse down counter circuit. Thereby, a main drive pulse generating circuit is not subjected to control pulse down by the pulse down counter circuit, and therefore, it is prevented that the main drive pulse is subjected to pulse down unnecessarily.

摘要： An electronic timepiece can reduce a burden imposed on a user who performs a manipulation for correcting the positional displacement of a pointer when a position of the pointer is displaced due to the demonstration of the pointer movement. The electronic timepiece includes: a pointer which is rotated in a first direction based on a manipulation signal corresponding to a manipulation from the outside; and a control part which performs the demonstration of the pointer movement in which the pointer is rotated in a second direction opposite to the first direction and the first direction, wherein the pointer is positioned at a position where a rotational angle in the first direction from a preset reference position is smaller than a rotational angle in a second direction from the reference position.

摘要： The invention is intended to detect whether or not a stepping motor is rotated when being driven immediately after a pulse-down control accurately. A control unit drives the stepping motor with a first main drive pulse after the pulse-down control, and then drives the same with a correction drive pulse. A second detection circuit detects a state of rotation on the basis of a current flowing through the stepping motor when being driven with the correction drive pulse. The control circuit controls a drive pulse selection circuit so as to select the main drive pulse to be used for the next time on the basis of a result of detection of the second detection circuit. The drive pulse selection circuit rotates the stepping motor with the main drive pulse corresponding to a control signal.

摘要： When a stepping motor is driven to rotate by a main driving pulse, if an induced signal exceeding a reference threshold voltage is detected only in a third segment, a pulse down operation is performed, and the main driving pulse is not changed when the same is detected in at least a first and the third segments. When it is detected only in a second and the third segments, a rank-up is performed without performing the driving by a correction drive pulse and, when it is not detected in at least the third segment, the rank up operation is performed after the driving by the correction driving pulse.

摘要： In response to an instruction to start time measurement given by a start/stop button, an in-phase drive control unit outputs an in-phase control signal of a predetermined time width to a drive pulse generation circuit such that a stepping motor is driven, instead of by a first drive pulse, by an initial drive pulse of a longer drive time than the drive pulse. The drive pulse generation circuit rotates the stepping motor by a motor drive signal including a plurality of in-phase main drive pulses. The stepping motor is rotated by one of the main drive pulses included by the motor drive signal to rotate the chronograph hands.

摘要： In response to a system reset signal inputted into a system reset port, a control circuit sets a general-purpose port to a high level first. Then, when a mode A is set in an integrated circuit for electronic timepiece, the control circuit sets the general-purpose output port to a low level after an elapse of a first time and when a mode B is set, it sets the general-purpose output port to a low level after an elapse of a second time. In this manner, a mode information signal having a pulse width corresponding to the mode is outputted from the general-purpose output port. It thus becomes possible to reduce the size without adding a special configuration for mode confirmation and to perform a confirmation in a short time.
