Abstract
The present invention relates to a pen type step calculating device that uses vertical vectors with assistance of horizontal vectors of a sensing microswitch. The detection of the sensing microswitch achieves a sampling effect. The successive digital signals of the OFF/ON status are in turn accumulated by the calculator, and are then indicated on the LCD display board through an I/O circuit, thereby completely excluding possibility of calculating the values erroneously, and thereby efficiently enhancing the utility of the pen type step calculating device.
Claims7
A pen type step calculating device comprising:
- a barrel (1) having an upper portion and a lower portion, an opening (10) defined in said upper portion of said barrel (1);
- a transparent outer cover (11) mounted in said opening (10) of said barrel (1);
- a battery sleeve (12) mounted in said upper portion of said barrel (1) and containing at least one battery (121) therein;
- a sensing circuit board (2) mounted in said upper portion of said barrel (1) and connected to said battery sleeve (12);
- and
- a press button switch (13) mounted in said upper portion of said barrel (1) and connected to said sensing circuit board (2);
- wherein, said sensing circuit board (2) includes:
- an LCD display board (20) for providing display of steps/distance/heat capacity;
- a sensing microswitch (21) respectively for detecting changes of vertical vectors and horizontal vectors;
- an LED (23) for providing status display;
- a calculator (24) for receiving digital signals to execute an accumulative operation;
- a comparator (25) for providing comparison of values;
- and
- a decoder (26) containing an operation unit therein.
