Disclosed is a sound generation device including a receiver which receives a sound emission instructing signal in which time data is included and a difference calculator which calculates a difference between a timing indicated in the received time data and a timing when the sound emission instructing signal is received by the receiver, when the sound emission instructing signal in which the time data is included is received. The sound generation device further includes a histogram creator which creates a histogram on the basis of the calculated difference and a difference calculated previously, when the difference is calculated and a timing controller which controls a timing for supplying the received sound emission instructing signal to a sound emission unit on the basis of the calculated difference and a most frequent difference in the created histogram, when the difference is calculated.

An electronic stringed instrumentincludes a string-pressing sensorthat detects a state of contact between each of a plurality of fretsand each of a plurality of strings. A CPUdetects that picking of any of the plurality of strings, provides a sound generation instruction to a connected sound sourceto produce musical sound of a pitch determined based on the detected state of contact, detects a vibration pitch of the stringof which picking was detected, and corrects the pitch of the musical sound generated by the connected sound sourcebased on the detected vibration pitch.

Upon an operation to full-press a shutter button being detected, a CPU detects human faces included in a picture imaged by an imaging unit, counts the number of the faces, and stores the number of the counted faces in a predetermined area of a memory unit. Thereafter, the CPU again detects faces included in an imaged picture and counts the number of the faces. When the number of the counted faces is equal to or smaller than the number of the faces stored in the predetermined area of the memory unit, the CPU repeats the process of detecting faces included in an imaged picture and counting the number of the faces. Meanwhile, when the number of the counted faces has increased from the number of the faces stored, the CPU records a picture that is to be imaged after a predetermined period of time passes in a recording medium.

A processor outputs a state signal representing the process state toga reset circuit. Upon reception of a reset signal from an external reset switch, the reset circuit outputs the reset signal to the reset terminal of the processor under the condition that the state signal allows a reset operation. The reset circuit also has a counter for starting a count operation upon reception of an externally input reset signal. Even when the processor is in a runaway state and cannot output the state signal for allowing the reset operation, a forced reset signal is supplied to the processor after a predetermined time is counted by the counter.

Sound information is binarized by delta modulation or adaptive delta modulation. The resulting data is subjected to pulse wide modulation and the resulting data is delivered to a reproducing device, which detects a leading edge of a received signal pulse to produce a self operation timing clock to thereby reproduce a sound. When the reproducing device detects the absence of edges for a predetermined interval after the edge detection, it turns off a power source for an analog circuit to suppress power consumption.

A compact electronic calculator having a graph display function of the invention has function keys for inputting functional formulas, a memory for storing an input functional formula, range input keys for inputting range data for variables in the formula, a memory for storing the range data, and a read-only memory (ROM) for storing a control program which sequentially calculates the values of the dependent variable for the independent variable with an ALU in accordance with the functional formula and the range data and which displays the calculated values on a display component.

In a printing control device for a thermal printer, a character read out from a character buffer for storing characters to be printed is supplied to a decoder and is then output from a character generator as a dot signal. In response to the dot signal from the character generator, an on-time preparing circuit outputs an on-time signal having a time duration determined by the number of dots associated with the dot signal or by the number of characters determined by the number of dot patterns. A voltage is applied to printing elements of a printing head for performing a printing operation for a time period determined by the duration of the on-time signal from the on-time signal preparing circuit.
