First Claim
1. A power supply control device comprising:
- a power supply means configured to supply power to a pointer instrument that notifies a predetermined measurement amount by a comparison between a rotating pointer and an indicator indicated by the pointer;
a first control unit operated by the power supplied from the power supply means and configured to control driving of the pointer instrument and supply of power from the power supply means to the pointer instrument; and
a second control unit capable of being electrically connected to a prescribed external device and configured to control supply of power from the power supply means to the external device,wherein the external device is operated by the power supplied from the power supply means,upon receiving a prescribed input command, the first control unit causes the power supply means to stop supplying power to the pointer instrument and, in response to the stoppage, the second control unit causes the power supply means to start supplying power to the external device that is electrically connected to the second control unit.

Abstract
Provided are a power supply control device, which is configured such that a current supplying capacity required by a power supply means can be reduced even when power is supplied to a prescribed external device, and an instrument device equipped with the power supply control device. The power supply control device is equipped with: a first power supply means (1000) for supplying power to a pointer instrument (30); a first control unit (100) that operates with power from the first power supply means (1000) and controls driving of the pointer instrument (30) and supply of power from the first power supply means (1000) to the pointer instrument (30); and a second control unit (200) for controlling supply of power from the first power supply means (1000) to an external memory (500). Upon receiving a prescribed command, the first control unit (100) causes the first power supply means (1000) to stop supplying power to the pointer instrument (30), and the second control unit (200) causes the first power supply means (1000) to start supplying power to the external memory (500) in response to the stoppage.
