  "textContent": "A compact information device and a shortened unlatch time are enabled in an information device 10 that resumes supplying DC power to internal circuits as a result of a latch circuit unlatching when the supply of DC power to an internal circuit including a CPU is stopped. A printer has a CPU 17, tactile switch 12, smoothing capacitor 13, switch circuit 14, a switch control signal generator 15 including a latch circuit 15a, and a potential difference detection circuit 16. The latch circuit 15a and potential difference detection circuit 16 operate with voltage Vin2. The CPU 17 outputs a start latch signal VLT when the operating mode changes from a power supply mode to a power cutoff mode. When the tactile switch 12 turns off, the potential difference detection circuit 16 outputs a unlatch signal VRST. When the unlatch signal VRST is input, the latch circuit 15a unlatches.",
