Title: Full bobbin aligning recovery device
Inventor: MATSUZAKA SHIGEAKI
IPC: B65G43/08
Filed: 1991-02-21
Abstract: PURPOSE:To simplify packing of full bobbins in a recovery box by a method wherein the direction of the full bobbin conveyed by a conveyor is changed and aligned in the recovery box by means of a moving chute. CONSTITUTION:When full bobbins 20 are conveyed by a conveyor 3, the full bobbins 20 are detected by a sensor. The direction of the full bobbin 20 is changed into a direction crossing orthogonally to the conveyance direction of the conveyor 3 by a guide 21 extended from a chute 6 mounted on the side of the conveyor 3 and when the full bobbins are dropped, the full bobbins are arranged in a good order by means of a flow straightening plate 2. A chute 6 is moved in the same direction as or opposite direction to the moving direction of the conveyor 3 according to a speed at which the full bobbin 20 is detected by a sensor. The full bobbin 20 is fed to a recovery box 31 through the chute 6. When the chute 6 is detected by an approach sensor arranged to the end in a moving direction of the chute, a recovery box mounting table 30 is lowered by one stage by means of recovery elevating devices 28 and 29. This constitution moves the chute 6 in one-way and lowers the recovery box mounting table 30 each time the chute is detected by the approach sensor.

Then the zooming ratio is detected and when the zooming ratio is subject to zoom-down (up) from the telescopic (wide angle) side to the wide angle (telescopic) side based on the zooming ratio, the aspect ratio of the lateral length with respect to the longitudinal length of the video image of the picked-up pattern is decreased (increased) in response to the zooming ratio. Thus, a powerful pattern with a laterally wide sense is obtained and a monitor picture whose luminous quantity is always stable is obtained.

Abstract: PURPOSE:To omit an operation to switch a processing mode for only one character by providing respective processing means to convert the size of one character from a current input mode when inputting the character by a shift key and a character key. CONSTITUTION:A processing part 13 is composed of a CPU 13a and memory 13b equipped with an English input flag 13c, and the CPU 13a executes various processings according to data and programs for various processings stored in the memory 13b. The processing part 13 detects the English input mode designated from the keyboard of an input part 11 and judges whether the designation is the input mode of the capital or the input mode of the small letter. In the case of the capital, '1' is set to the flag 13c and in the case of the small letter, '2' is set to the flag. Afterwards, when a shift key 11a and an English character key are simultaneously pushed down, for the input character while referring the flag 13c, when the flag is '1', the small English letter is outputted and when the flag is '2', the English capital is outputted. Thus, it is not necessary to switch the processing modes for the capital and small letters only for one character.
