Abstract: A cash counting apparatus for cashbox comprises a case arranged within the cashbox, a sliding block movably arranged at an upper side of the case, a swing arm pivotally arranged in the case, and a circuit board with a plurality of contacts. The swing arm has one end pivotally driven by the sliding block and a probe on another end. The sliding block is moved laterally by an inserted coin, and the probe is swung due to the lever action of the swing arm. The probe is selectively in contact with one of the contacts according to the sizes of the inserted coin.

Abstract: A dancing doll is controlled by acoustic or optical signals. The doll has sensor for detecting acoustic or optical signal and has an IC controller activated by the sensing result of the sensor and then controlling the body motion and singing of the doll.

Abstract: A candle stand detects the candlelight from a candle and provides audio and visual effect according to the detected candlelight. The candle stand has a through hole thereon and a light detector corresponding to the through hole. The light detector detects light from the candle through the through hole and triggers a controller to provide audio and visual effect.

Abstract: An essential oil evaporator has timing control by a controller for audio and visual effect. The controller controls a loud speaker and an LED lamp in a progressive and synchronous way. Moreover, the controller also activates a heater through a trigger unit. Therefore, the user can aware the turn on and turn off of the heater with the help of audio and visual effect.

Abstract: The present invention provides a dynamic searching device for toys, having at least two optical sensors to sense a target and a control circuit to compare the sensed signals of the two sensors and control a driver to move the toy, thus giving the toy dynamic movement.
