    摘要: The present invention provides a printing drum for a rotary stencil printing device, comprising: a clamp for clamping a leading edge of a stencil master plate sheet along a line extending axially on an outer circumferential surface of the printing drum; and cutting device mounted on the printing drum for cutting the stencil master plate sheet to define a trailing edge of the stencil master plate sheet mounted on the printing drum. By thus providing the cutting device on the printing drum, the stencil master plate can be accurately cut because the cut length of the stencil master plate can be determined in relation with the circumferential length on the printing drum, and the cut edge of the stencil master plate can be made always exactly parallel to the axial line of the printing drum because there is no relative movement in the feeding direction between the stencil master plate sheet and the cutting device.

    摘要: Disclosed is a chronograph timepiece in which it is possible to prevent the chronograph drive timing and the magnetic field detection timing from overlapping each other to unnecessarily effect driving with correction drive pulses. A processing unit controls drive circuits so as to drive a time indication motor and a chronograph indication motor with a predetermined timing based respectively on timekeeping information obtained and chronograph measurement information obtained, and effects control such that a magnetic field detecting unit detects a magnetic field with a predetermined timing; when the drive timing for the chronograph indication motor and the magnetic field detection timing for the magnetic field detecting unit overlap each other, the processing unit changes the magnetic field detection timing for the magnetic field detecting unit so that the drive timing for the chronograph indication motor and the magnetic field detection timing for the magnetic field detecting unit may not overlap each other.

    摘要: A stepping motor control circuit includes a rotation detecting means for detecting an induced signal generated by rotation of a rotor of a stepping motor, and detecting a rotation state of the stepping motor according to whether the induced signal exceeds a predetermined reference threshold voltage in a predetermined detection section, and a control means for controlling driving of the stepping motor by using any one of a plurality of main driving pulses having energy different from each other or a correction driving pulse having energy higher than energy of each main driving pulse according to a detection result of the rotation detecting means. The detection section is divided into a first section immediately after driving with the main driving pulse, a second section after the first section, a third section after the second section, and a fourth section after the third section, and the control means lengthens the third section subsequent to the second section when the rotation detecting means has detected an induced signal exceeding the reference threshold voltage in the second section, and controls the driving of the stepping motor by selecting a driving pulse based on a pattern of an induced signal in the first to fourth sections.
