The invention comprises a signalling device for reminding a person to follow certain eating habits. The device acts to sound an alarm at certain timed intervals in conjunction with the placement of a utensil upon the device to indicate to the person when he is eating too fast or without suitable interruption. The device has a photo cell at a convenient location on top of the device to receive the utensil so that the utensil will block out the light and cause the photo cell to react, in turn causing the circuitry of the device to react. If the operator removes the utensil from the photo cell for each bite and replaces it at that location, the device acts to regulate the amount of time the operator has the utensil away from the photocell presumably to take a bite and regulate the amount of time the utensil must be left on the photo cell between each bite. The operator must replace the utensil over the photo cell within a specified period of time, timed by the device, after removing it presumably to take a bite, or the alarm will sound when that specified time has elapsed, which period of time is considered adequate for taking a bite of food. The operator, once he has replaced the utensil over the photo cell, must leave it at this location for a specified period of time, as timed and programmed by the device, before he can remove it again to presumably take another bite, or the device will also cause the alarm to sound if he removes it before that time has elapsed, indicating to the operator he has removed the utensil from the photo cell too soon for another bite, in the time estimation as programmed or timed by the device.
