Title: Reel driving device for tape recorder
IPC: G11B15/50
Filed: 1993-01-25
Abstract: PURPOSE: To quickly change modes of a tape recorder by connecting one pair of reel tables to a driving gear via one pair of intermediate gears respectively and constituting a tension means out of a fixed gear and a drift gear. CONSTITUTION: At the time of unloading a tape cassette, a cam lever 61 is rotated counterclockwise by rotating a cam 60. The intermediate gears 40 and 50 are brought adjacent to each other by rotating links 62 to 65 in the direction of approaching each other by springs 66 and 66'. A distance between the gears 40 and 50 and the driving gear 30 becomes shorter than a space between the reel tables 10 and 20. Subsequently, the tables 10 and 20 are stably mounted with the tape cassette, and a deck 100 is loaded. Then, the cam lever 61 is rotated clockwise by the cam 60, so that driving disks 11 and 21 of the tables 10 and 20 are meshed with each other. At the time of a play F.F. mode, the gear 30 is driven clockwise, and disks 14 and 24 are also rotated clockwise. Then, the driving disk 21 and a driven disk 22 are rotated, and a felt table 27 is rotated to give constant tension to a tape.

Title: Bearing structure
Inventor: MORIKAWA FUMIHIRO
IPC: F16C17/08
Filed: 1989-01-19
Abstract: PURPOSE:To prevent the generation of minute vibrational components and reduce the noise made at the time of rotation considerably by providing a thrust force bearing seal chamber part in which one end part of an axis of rotation is rotatably inserted through sealing parts as well as a fluid is sealed hermetically. CONSTITUTION:A thrust force bearing seal chamber 5 in which one end 2 of an axis of rotation 1 is rotatably inserted through sealing parts 3 is formed. A fluid 4 is hermetically sealed into this seal chamber 5. When the axis of rotation 1 moves in the direction of an arrow D, the edge surface of one end part 2 of the axis of rotation 1 presses the fluid 4, so that the capacity of the seal chamber 5 is decreased, and thereby liquid pressure is heightened, thus supporting the axis of rotation elastically. As a result, the generation of minute vibrational components is prevented and the noise made at the rotating time of a rotor can be considerably reduced.

IPC: G06F1/24
Filed: 1987-01-21
Abstract: PURPOSE:To prevent an erroneous initializing action due to the noises without providing a noise removing circuit and also to simply and surely avoid the initialization due to a misoperation, by providing an initialization control flag and a counter into a memory. CONSTITUTION:When a timepiece IC 1 is initialized at the time of the replacement of a battery E, etc., a reset switch 2 is turned on and a reset signal containing the H-level voltage of the battery E is supplied to a reset terminal R. Then a CPU decides the set state of a reset flag in a memory and sets the flag when a 1st reset signal is inputted to the terminal R. Simultaneously, a counter is actuated. Then the initialization processing is carried out when a 2nd reset signal is supplied before a fixed count time set by the counter elapses. While the flag is cleared when the 2nd reset signal is not supplied. Thus it is possible to prevent the erroneous initializing action due to the noises without adding a noise removing circuit to the terminal R. Furthermore the initialization due to the misoperation can be simply and surely prevented.
