Abstract: A flat-type input unit capable of outputting information regarding a position where a finger touches as coordinate data is provided in a casing of an input device. A main-switch unit and sub-switch units operated by the flat-type input unit are also provided in the casing. When ON output signals are simultaneously supplied from the main-switch unit and one of the sub-switch units, the flat-type input unit determines a position where the finger touches by performing a detection operation. It can be determined on the basis of the position whether the main-switch unit or the sub-switch unit is controlled. Moreover, since pressing any position of the flat-type input unit can cause the main-switch unit to supply an ON output signal, a confirmation input can be performed easily with the ON output signal supplied from the main-switch unit.

Abstract: A maximum value of the magnitude of sound detected by a microphone is detected by a peak hold circuit and is sent to a CPU. A discriminating unit is provided in the CPU. In the discriminating unit, plural thresholds are set and it is discriminated which threshold the maximum value exceeds. Any of switching means H, M and L is switched according to the discrimination and a switching signal is generated. According to a type of the switching signal, proceedings of a game program vary.

Abstract: A thermal head controller includes a central processing unit (CPU), a storage unit, an arithmetic unit, a controller, and a thermal head. The CPU reads print data stored in the storage unit. The storage unit holds print data to be printed on a stamp print face, which are transferred from a host computer. The CPU transfers the read data to the arithmetic unit, and causes the arithmetic unit to perform print-pattern processing. The arithmetic unit stores pattern data in its shift register before processing the stored pattern data. The print-pattern processing is performed so as to prevent fine print from being erased due to the deformation of the stamp print face caused by heat conduction in polyethylene foam sheet when the stamp print face is formed. The CPU uses the controller to control the thermal energy of dots positioned on the border between print dots and non-print dots on the thermal head.
