Abstract: PURPOSE: To eliminate the need to adjust sensitivity and to perform mass-production by arranging vibrating pieces of a tuning fork type vibrator inside and outside a case sealed to a body to be detected and detecting a load directly by the vibrating piece outside the case.
CONSTITUTION: The load detecting device is constituted by fitting the earth terminal 24 of the tuning fork type vibrator 23 to a printed board 22 and arranging a vibrating piece 23a outside the case 20 and the other vibrating piece 23b inside the case 20. Consequently, when the load of toner mass is placed on the vibrating piece 23a of the tuning fork vibrator 23 which is arranged outside the case 20, this vibration circuit stops oscillating or decreases in the amplitude of an oscillation output voltage. Consequently, the presence of toner is detected from the stop of vibration or decrease in the amplitude of the vibration output voltage. In this case, there is no variation in sensitivity caused by an inclusion between the vibrating piece which detects the load and the boby to be detected, so that the device which eliminates the need for sensitivity adjustment and is easily mass-produced is obtained.

Abstract: PURPOSE: To thicken film thickness of an elastic seat by arranging a load transmitting member at a part except the neighborhood of the tip part of a vibrating reed of a tuning fork vibrator.
CONSTITUTION: The tuning fork vibrator 3 is made of a permanently elastic metal plate punched almost in specified width and bent in U-shape and the load transmitting member 5' is punched with the vibrating reed 3a of the tuning fork vibrator 3 in a body when the permanently elastic metal plate is punched and bent toward the direction of the outside of the vibrating reeds 3a, 3b from one side of the vibrating reed 3a. An earth terminal 4 is fitted to the vibrator 3 with spot welding or the like and the tip face of the load transmitting member 5' is abutted on the elastic seat 6 stuck to the opening of a load detecting part 1a of a case 1 and the earth terminal 4 is soldered to an earth electrode of a printed board 2. In this way, since the load transmitting member 5' is positioned near the base of the vibrating reed 3a, the film thickness of the elastic seat 6 can be thickened and accordingly, the situation like vibration stopping cannot take place unless considerably high film pressure is applied.

Abstract: PURPOSE:To eliminate the need for clamping of tuning fork oscillator at cutting and to automate the frequency adjustment by cutting a tip corner of an oscillating chip of a tuning fork oscillator by a rotary grinder in the broadwise direction of the oscillating chip. CONSTITUTION:The specific oscillating frequency of the tuning fork oscillator 5 finished for assembling is measured and the deviation between the measuring value of the specific oscillating frequency and the objective specific oscillating frequency is obtained. Then, whether this deviation is within the permissible value or not is discriminated and when the deviation is at the outside of the permissible range, a rotary grinder rotating in the arrow Ar2 is contacted to the tip corner 11 of oscillating chips 6, 7 of the tuning fork oscillator 5, said tip corner 11 is cut as shown in alternate long and two short dashes lines in the broadwise direction of the oscillating pieces 6, 7 and this work is continued until the tip corner reaches within the said permissible range.

Abstract: PURPOSE:To obtain a linear output for a wide-range load by paying attention to linear variation of oscillations with the load on the oscillating piece of a tuning- fork oscillator, and arranging a load detection part except at a sensitive part near the tip of the vibrating piece. CONSTITUTION:An earth terminal 4 is fitted to the tuning-fork type oscillator 3 by spot welding, etc., the front end surface of a load transmission part 5' is brought into contact with an elastic sheet 6 spread in the opening of the load detection part 1a in a case 1, and the earth terminal 4 is soldered to the earth electrode of a prined board 2. Then, the load transmission part 5' is near, so when the oscillating piece 3a oscillates, output voltage variation and frequency variation with the wide-range load are detected by the load detection part 1 almost linearly. Consequently, the permissible range of contacting pressure with the elastic sheet, etc., contacting a body to be detected directly is windened and this device is adapted to mass-production.
