Abstract

A measuring apparatus (100, 200, 300, 400) is an optical measuring apparatus provided with a probe portion (20, 20a, 20b, 20c) and a main body portion (10, 10b, 10c), which are electrically connected to each other. The probe portion has: a light source (21, 26); a reference voltage generating device (24) configured to apply predetermined reference voltage to the main body portion; and a storing device (25) configured to store therein in advance current adjustment information, which is information for adjusting a drive current to be supplied to the light source. The main body portion has: a drive current supplying device (12, 12a, 12b) configured to supply the drive current to the light source, due to the applied reference voltage; and a controlling device (11) configured to control the drive current supplying device on the basis of the stored current adjustment information.

Claims

1. A measuring apparatus of an optical type comprising a probe portion and a main body portion, which are electrically connected to each other by a connecting cable,

said probe portion having:

a light source;

a reference voltage generating device configured to apply predetermined reference voltage to said main body portion; and

a storing device configured to store therein current adjustment information, which is information for adjusting a drive current to be supplied to the light source,

said main body portion having;

a drive current supplying device configured to supply the drive current to the light source, due to the applied reference voltage; and

a controlling device configured to control the drive current supplying device in such a manner that the drive current has a drive current value to be supplied to the light source, on the basis of the stored current adjustment information,

wherein said connecting cable is formed integrally with said probe portion, and has a connector at one end of said connecting cable configured to be attached to or be detached from said main body portion.

2. The measuring apparatus according to claim 1, wherein the storing device further stores therein usage time information, which is information indicating a usage time of said probe portion.

3. The measuring apparatus according to claim 2, wherein the controlling device updates the usage time information, according to an operating time of said measuring apparatus.

4. The measuring apparatus according to claim 2, wherein said main body portion further has a notifying device configured to notify a user of said measuring device if the usage time indicated by the stored usage time information is greater than a predetermined value.

5. The measuring apparatus according to claim 1, wherein said measuring apparatus is a blood flow detecting apparatus.
