Title: Reel locking mechanism of tape cassette
Inventor: HASHIZUME KENJI
IPC: G11B23/087
Filed: 1994-03-29
Abstract: PURPOSE:To realize a secure locking operation even after a tape cassette is left under a high temperature for a long time by a method wherein an opener which opens a pair of claws is provided at a center between a pair of release parts. CONSTITUTION:When a cassette is loaded on a recorder, an operation pin is inserted into an insertion hole 20 and draws the hole 20 to the right (backward) against a spring 25. A sliding part 8 retreats and locking claws 10 and 12 are pushed by locking release parts 26 and 28 and the distance between the claws 10 and 12 is narrowed and the claws 10 and 12 are removed from the circumference of a reel. When the cassette is unloaded from the recorder, the locking member 6 advances by itself. Immediately before the locking member 6 advances to the locking position, the bent parts 22 and 24 of the claws 10 and 12 are brought into contact with a locking opener 30. The clwas 10 and 12 are forcibly opened by the tapered or widening guide plane of the locking opener 30 and brought into contact with the locking release parts 26 and 28. With this constitution, an idle movement is not produced while the claws 10 and 12 are moved between the two positions, so that the smooth movement can be achieved with a small stress and the secure locking can be realized even after the tape cassette is left under a high temperature for a long time.

Title: Continuous paper folding device and printing device
Inventor: ASADA HIROYOSHI
IPC: B65H45/107
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To surely prevent the failure in folding of the continuous paper by contacting a point part of a swing guide feed-out part with a continuous paper surface when a swing guide is positioned at a left or right maximum swing position. SOLUTION: A swing guide 1 starts its swinging to right after it reaches a maximum swing position. It is important to keep the application of the optimum tension to the continuous paper 40 by the time when the swing guide 1 passes through a neutral position, and further reaches the maximum swing position at right. That is, a point of the continuous paper 40 is gripped by a claw belt, a paper tray 11 and a positioning stopper, and a state that the continuous paper 40 is contacted with a point 30a of a swing guide point member, is realized at least near the maximum swing position. Whereby the force is efficiently acted on the perforation when the perforation passes through the point 30a of the swing guide point member, the folded line is restored, and a mountain-like fold part is formed.

IPC: B60T8/175
Filed: 1993-03-16
Abstract: PURPOSE:To make the pressure control actuator of a brake control device low-priced and high in reliability. CONSTITUTION:The chamber 13 of a control cylinder partitioned by a piston 11 is connected to a wheel cylinder 27 and also to a master cylinder 30 through a cutoff valve 2. At the time of moving in the chamber volume enlarging direction from the neutral position, the piston 11 comes in contact with a return spring 17 with powerful initial spring force set thereto. ABS-traction control is performed by closing the cutoff valve 2 to motor-drive the piston 11. Accordingly, when the thrust by an electric motor 20 is made zero after the pressure reduction of ABS control, the piston 11 is reset rapidly and positively into the neutral position and returned to neutral with light braking force also after the pressure intensification of traction control by making motor thrust zero. Only one cutoff valve is thereby needed, and seal parts are few.
