Abstract: A belt driving apparatus has a motor for generating the driving force, a toothed driving pulley rotating by the driving force, an endless toothed belt wound on the pulley, wherein a first surface of the toothed belt has teeth corresponding to teeth of the pulley and a second surface of the toothed belt is substantially smooth, an auxiliary roller for holding the toothed belt in a gap defined by the pulley and the auxiliary roller, a roller holding unit for holding the pulley and the auxiliary roller to be able to respectively rotate on axes of the pulley and the auxiliary roller and maintaining the gap between the pulley and the auxiliary roller and an urging member for urging the roller holding unit in a direction to the toothed belt around the pulley in order for the auxiliary roller hold by the roller holding unit to provide a tension to the toothed belt.

Abstract: A unit supporting device supports a unit that can be inserted into an accommodating position and pulled out to an operable position while defining a position of the unit with respect to a member opposite to the unit. A configuration for setting a positional relationship between the unit and the member in a process in which the unit is inserted toward the accommodating position is provided on the unit and the member.

Abstract: An image forming apparatus includes an optical writing device. The optical writing device includes an optical writing unit that emits laser light beams toward image carriers, an outer case that accommodates the optical writing unit, and air supplying devices that supply air into the outer case. The outer case includes openings through which the laser light beams pass. Another image forming apparatus includes an optical writing device that emits laser light beams toward image carriers to form latent images thereon, partition members that are interposed between the image carriers and the optical writing device and that have openings elongating along a scanning direction of the optical writing device, and shutter mechanisms including shutter members to open and close the openings. The laser light beams are emitted from the optical writing device toward the image carriers through the openings.

Abstract: The present invention provides a box sealer for attaching adhesive tape in an L-shape on corners of a box for medical drugs, cosmetics, etc. The box is first received at a rectangular corner furnished on a top surface of the box sealer, and adhesive tape of a predetermined dimensions is sent out from below and is cut. By sliding attachment plates at the corner of one side and at the bottom of the box, the adhesive tape is attached in the L-shaped form. Knurled rollers for sending out the adhesive tape are furnished in tandem, and one of the rollers is rotated by twice as many revolutions as the other roller. Further, a microswitch for detecting the box and rotating a motor is mounted near the rectangular window of the housing, and a pair of operating pins of the microswitch are provided in parallel.

Abstract: A member for a car body in which concave and convex beads can be positioned appropriately regardless of a complexity of a shape of the member, and the efficiency of energy absorption can be improved. The member includes side faces having concave beads provided on the side faces at positions corresponding to dip portions of a buckling waveform produced by an initial buckling load applied to the member in a state of having no bead; convex beads provided on the side faces at positions corresponding to peak portions of the buckling waveform; and flat portions without any bead, formed between each adjacent concave bead and convex bead. The side faces may also have edge beads provided on edges of the side faces at positions corresponding to a dip portion of the buckling waveform which is closest to a front end to be subjected to a crushing load.

Abstract: A method of determining the positions of beads, capable of determining appropriate positions easily. The method includes the steps of obtaining a buckling waveform on the member without any bead; analyzing the obtained buckling waveform to determine concave portions and convex portions of the buckling waveform; and determining the positions of the beads in accordance with the concave portions and the convex portions of the buckling waveform.

Abstract: An adhesive tape applicator for applying a fraudulent-opening preventive adhesive tape in an "L" form on the corners of a package of medical articles or the like. For easy peeling of the adhesive tape, the apparatus according to the present invention is so arranged that the adhesive tape has superposed on the adhesive side thereof a separate paint foil tape, the adhesive tape and paint foil tape are supplied from their respective sources, the paint foil tape thus superposed on the adhesive tape is stuck by a hammer to transfer a portion thus stuck of the paint foil to the adhesive side of the adhesive tape, thereby forming a non-adhesive lug piece, the adhesive tape having the non-adhesive lug pieces thus formed thereon is fed toward the package carrying path from under the path, the adhesive tape is cut along the boundary between the transferred paint foil and the adhesive area and attached by being pressed by an application roller against the corner of the package.

Abstract: A binding apparatus for sealing bags containing any cakes, bread or the like by twisting a ribbon-like plastic-made binding cord or tie on the gathered open end or neck of the bag, with a tag placed under the tie and on the gathered bag neck. This apparatus comprises a bag carrying/gathering means which is a pair of intermittently rotating chains extending parallelly to a bag carrying conveyor; a tie delivering means consisting of a drum having provided on the outer circumference thereof stationary gather receivers and moving tie keep pins, and a pair of swing levers to bend the tie into a reversed U-shape for easy mounting on the gathered neck of the bag; a pushing member to move the swing levers downward and a tie cutter to cut the tie in place to a predetermined length; a tie twisting means to catch and twist the tie on the gathered bag neck and the tag placed in position on the gathers of the bag neck.

Abstract: The present invention relates to an apparatus for adhering straws, each being packed in a plastic film, to external surfaces of beverage vessels for milk, juice, etc. which are sold by vendor machines. Specifically, a straw adhering apparatus for beverage vessels wherein a continuous laminated plastic film strip which incorporates straws separately and individually and is provided with an array of punched feed holes at upper and lower end parts of the strip is cut into individual straw packs by a cutter on the way of the strip feed passage. Upper and lower edges of each straw pack are delivered respectively by a pair of seizing feed belts to the main carrying conveyor path for a beverage vessel to which the straw pack is adhered to an external surface of the beverage vessel onto which an adhesive agent is applied in advance. An adhesion retaining belt which maintains a state of adhesion of the straw pack to the beverage vessel is provided at a side of the main carrying conveyor.
