Abstract: A spectrophotometer 1 comprises a control unit 45 with a warming-up determination unit 452 that determines the completion of a warming-up based on a variation amount of a detection signal in a predetermined duration when a light detector 7 detects a light from a sample chamber without loading the sample. Specifically, the warming-up determination unit 452 calculates a difference between a signal intensity of the detection signal detected by the light detector 7 at the time when the predetermined time passes and a signal intensity of the detection signal detected by the light detector 7 at a previous time and determines that a warming-up is complete when a value of the difference is less than a first threshold value. The warming-up determination unit 452 automatically determines the completion of warming-up independently from the determination by the user.

Abstract: In the touch panel device, when a slide operation in an oblique direction by a user is performed, out of a content displayed on the display screen 11 at that time, a region surrounded by an imaginary rectangle in which a start point Pa and an end point Pb of the slide operation are opposing corners and either one side of the imaginary rectangle is parallel to either one side of the display screen is displayed in an enlarged manner so as to fill the entirety of the predetermined region 12 of the display screen 11. With this, an intuitive display enlargement operation can be performed even for a touch panel device not supporting a multi-touch operation.

Abstract: An analysis system 10 includes a plurality of spectrophotometers 1, a memory storage 11, and a control terminal 12. The spectrophotometer 1 further includes a light source 2, a light detector, and an optical element that introduces light from the light source 2 to the light detector. The memory device 11 stores the information as the control information 110 relative to the light amount of the light detected by the light detector 6 right after replacement when replacing the light source of the spectrophotometer 1. A replacement timing determination unit 125 of the control terminal 12 reads out a control information 110 in the memory device 11 and determines the replacement timing of the optical element based on the value of the light amount information of the read-out control information 110.
