Title: Film unit with lens
Inventor: YOKOO HIROKAZU
IPC: G03B17/04
Filed: 1994-09-22
Abstract: PURPOSE: To improve the durability of a drive transmitting system by preventing the skipping and chipping off of a tooth, even if the driving torque of a motor is suddenly changed. CONSTITUTION: A row of teeth 37 having an involute tooth form and a row of teeth 38 having a triangular horizontal cross-section are integrally fanned in a winding knob. When a film unit with a lens is attached to a film winding device 3, the row of teeth 37 is engaged with the row of teeth 64c of the connecting gear 64 of the film winding device 3. When the motor is driven, the driven force is transmitted to the connecting gear 64 through a gear and a clutch gear 63 to rotate the winding knob in the winding direction of the film. When the winding of a frame of the film is completed, the pawl of a locking lever is engaged with the low of teeth 38, to inhibit the rotation of the winding knob. At this time, a load is applied to the engaged part, but the skipping and chipping off of the tooth can be prevented because the involute tooth form is a row of teeth.

Title: Base device of saber saw
Inventor: TACHIBANA TOSHIHIKO
IPC: B23D51/02
Filed: 1999-08-11
Abstract: PROBLEM TO BE SOLVED: To absorb a cutting reaction by mounting a base to be pressed against a material to be cut, in a freely rotatable manner, at the tip of a base fixing member fitted to a saber saw body, in a freely movable fashion, in the shuttle moving direction of a blade and energizing the upper part of the base toward the saber saw body by means of a spring. SOLUTION: In the saber saw which shuttle drives a plunger with a straight line saw blade 5 by means of an electric motor, as a cutting tool, a base fixing member 2 is mounted, in a freely movable manner, on a saber saw body 1 in the shuttle-moving direction of the blade 5. Further, a base 3 is pivotally fitted to the base fixing member 2 by means of a pin 6, and is energized in a direction where the base 3 is pressed against a material 10 to be cut with the help of a spring 4 wound around the pin 6. Thus the spring 4 absorbs a collision impact which happens to repeatedly occur between the base 3 and the material 10 when the impact is caused by a cutting reaction. Consequently it is possible to restrain the vibration during cutting and thereby prevent the working efficiency from being deteriorated.
